N2  - Phosphate fertilizers manufactured by the usual methods are toxic to farm animals because of their high fluorine content. Two types of phos-phate fertilizer, produced by the Tennessee Valley Authority, namely fused phosphate rock (2 samples) and calcium metaphosphate, have a low fluorine content, the former 0.05 and 0.22 per cent, and the latter 0.57 per cent., respectively, and these were tested as sources of phosphorus. In experiments with rats, fused rock phosphate was found to be an excellent source of Ca and P but rats receiving the metaphosphate stored significantly less Ca and P than controls receiving comparable amounts of Ca and P in salts of known availability. The poorer utilization of the metaphosphate was not due to any toxic property.-J. S. Thomson.

In growth tests its P was 91 per cent. as available, based on liveweight increase, and 77 per cent. as available, based on P retention, as the P in Osbome and Mendel's salt mixture when given at a minimum level, and even more available when given at higher levels. It was as effective as bonemeal for growth, reproduction and lactation when the total P level in the diet was 0.4 to 0-5 per cent. Preliminary, tests with chicks showed that, for bone development in early life, the P in limestone-ferrophosphorus was as available as that in steamed bonemeal or in defluorinated rock phosphate. The original ferrophosphorus gave unsatisfactory results with both rats and chicks. W. Godden.

N2  - Studies were conducted from July 1969 to January 1972 in an outdoor recreation and conservation area in the Tennessee Valley region to provide information on the occurrence and biology of ticks involved in the maintenance and transmission of spotted fever and tularaemia in nature. A total of 22832 ticks of seven species was collected; 61851 were taken by dragging and 5981 from 951 animal hosts. Amblyomma americanum (L.) and Dermacentor variabilis (Say) account for 95% of the total. D. variabilis and A. americanum, the two established vectors of Rickettsia rickettsi and Pasteurella (Francisella) tularensis to man in eastern and south-eastern United States, were found abundantly throughout the area and were associated with large numbers of deer and raccoons. Other species, such as Haemaphysalis leporispalustris (Pack.), D. albipictus (Pack), Ixodes dentatus Marx, I. cookei Pack. and I. texanus Banks, were also recorded but in small numbers. Data on host relationships and seasonal activities are presented.

N2  - Granular formulations containing 1% Dursban or Abate (0,0,0',0'-tetramethyl 0,0'-thiodi-p-phenylene diphosphorothioate) were evaluated for the control of Aedes canadensis (Theo.), A. sticticus (Mg.), A. vexans (Mg.) and other mosquitos breeding in naturally and artificially flooded sites in the Tennessee Valley region of the United States. Except in one test, both formulations caused 99% reduction in larval numbers 24 h after application at 0.1 lb toxicant/acre. Laboratory tests of water from the treated sites showed that Dursban remained 100% effective for at least 25 days, while Abate became almost completely ineffective after 7 days. Dursban at 0.05 lb/acre ceased to be effective after 2 days. Abate did not affect the numbers of Ostracods, Salientia, Triclads or Isopods in the treated sites, and Dursban was detrimental only to Isopods. In other tests, both granular formulations and an emulsifiable concentrate of Dursban were applied at 0.1 lb toxicant/acre to breeding sites 10-14 days before they were flooded. Abate was ineffective in preventing mosquito breeding; the granular formulation of Dursban remained 100% effective for at least 30 days, and the emulsion formulation for at least 14.

N2  - Field and laboratory studies were carried out in Tennessee to investigate tillage as a means of controlling the production of floodwater mosquitoes (primarily Aedes vexans (Mg.) and Psorophora columbiae (D. & K.)) in grassy depressions and river floodplains. Tractor ploughing followed by disking produced control of mosquitoes ranging from 73 to 100%. This method of tillage displaced mosquito eggs from the top 12 mm of the soil to depths of 126 mm or more, thereby trapping larvae in the soil and preventing their further development and emergence as adults. Laboratory studies confirmed that this action produced the control effect.

N2  - The relationship between small mammals, Amblyomma americanum and Dermacentor variabilis was studied in an oak/hickory woods and an old-field habitat in Tennessee. The small mammals captured were Peromyscus leucopus, Microtus ochrogaster [Pitymys ochrogaster], M. pinetorum [P. pinetorum], Blarina brevicauda, Cryptotis parva, Reithrodontomys humulis and Mus musculus. Only 3 subadults of A. americanum were collected from small mammals, but high densities of free-living individuals were present. Small mammals were thus not considered to be principal hosts of that tick. In the woods, 15 individuals of Peromyscus leucopus were examined for ticks, with a mean of 0.03 nymphs and 1.4 larvae of D. variabilis per mouse. In the field, 49 individuals of P. leucopus were examined, with 0.3 larvae and 0 nymphs per mouse. A total of 68 larvae and 10 nymphs of D. variabilis were collected from Pitymys ochrogaster and 1 larva from P. pinetorum. Although males of Peromyscus leucopus travelled farther and had more ticks than females, no significant difference in numbers of ticks per mouse by sex and no significant correlation in numbers of ticks per mouse by weight, total length or maximum distance travelled were found. A small percentage of the mice carried most of the ticks. It was concluded that small mammals could reinfest a control area with D. variabilis but not with A. americanum.&lt;new para&gt;ADDITIONAL ABSTRACT:&lt;new para&gt;From an examination of the relationships between 7 species of small mammals, Amblyomma americanum and Dermacentor variabilis in an oak/hickory wood and an old-field habitat in Tennessee the authors conclude that small mammals could reinfest a control area with the latter species of tick but not with the former.Carolyn A.

N2  - A project on management of lone star ticks, Amblyomma americanum (L.), at Land Between the Lakes, a Tennessee Valley Authority recreational area in Kentucky-Tennessee, during 1984-1988, demonstrated the effectiveness and economics of three control technologies. Acaricide applications (chlorpyrifos at 0.28 kg [AI]/ha), vegetative management (mowing and removal of 40% overstory and 90-100% of midstory, understory, and leaf litter), and host management (white-tailed deer exclusion from a 71-ha campground with a single-line fence) provided 75, 70, and 64% mean controls of all life stages of the lone star tick, respectively. Combinations of acaricide applications + vegetative management, acaricide applications + host management, and acaricide applications + vegetative management + host management produced 94, 89, and 96% mean control of all life stages, respectively. The costs of acaricide applications (2 per year), vegetative management (2 mowings per year), and white-tailed deer exclusion (single-line fence) were $45, $150, and $30/ha/yr, respectively.

N2  - Nymphs of a common dragonfly, E. simplicicollis, were exposed to B. thuringiensis subsp. israelensis at 1.2 ppm once a week for an entire life cycle in a controlled laboratory environment. Eight weekly applications were administered to 2 treatment groups: external contact only, and external + internal contact using prey (mostly anopheline larvae) that had fed on B. thuringiensis. Each B. thuringiensis-treated group and a control group consisted of 15 nymphs. Mortality was not affected by B. thuringiensis applications. Repeated B. thuringiensis applications did not affect development to the adult stage, morphology or maiden flight capability. Nymph size of the external contact group, measured by hind femur length and head width, was substantially smaller compared with the control group in most instars from 4-12. However, adult size, based on head width and hind wing length comparisons, did not differ among the 3 groups. Prey consumption and instar duration, which were highly correlated, did not account for the differences in size. Sex ratio (lower proportion of large females in the external group) and initial size (slightly smaller in instar 2 in the external group) appeared to be the major factors contributing to the size differences in the external group. However, these variables were not responsible for the external + internal contact group being smaller in instar 10 compared with the controls, as sex ratios and initial size were equal. If repeated B. thuringiensis applications affect size in E. simplicicollis, the effect may be insignificant in terms of reproductive success, as published studies do not show a positive relationship between size and reproductive success in dragonflies.

N2  - Scientists at the Tennessee Valley Authority, and in collaboration with the U.S. Environmental Protection Agency, are continuing to develop and refine an innovative waste water treatment system referred to as reciprocating subsurface-flow constructed wetlands. Reciprocation relates to patented improvements in the design and operation of paired subsurface-flow constructed wetlands, such that contiguous cells are filled and drained on a frequent and recurrent basis. This operating technique turns the entire wetland system into a fixed-film biological reactor, in which it is possible to control redox potential in alternating aerobic and anaerobic zones. Reciprocating systems enable manipulation of waste water treatment functions by controlling such parameters as hydraulic retention time, frequency of reciprocation, reciprocation cycle time, depth of reciprocation, and size and composition of substrate. These improved wetland technologies have been used for treating municipal/domestic waste water, high strength animal waste water, and mixed waste water streams containing acids, recalcitrant compounds, solvents, antifreeze compounds, heavy metals, explosives, and fertilizer nutrients. Results from selected treatability studies and field demonstrations will be summarized with respect to conceptual design and treatment efficacy.

N2  - Hydraulic conductivities were determined for four onsite constructed wetlands systems located in northeast Alabama. These systems have operated continuously since 1992 or 1993. Water levels were measured for relatively steady flow rates that represented potential instantaneous maximum flows. Hydraulic conductivity of the gravel in each cell was calculated using Darcy's Law. Calculated values ranged from 340 to 8,400 m/day (1,100 to 27,700 ft/day) for pea gravel (size 8-9) to slightly larger gravel (size 6-7). The low value reflects substantial clogging and the high value reflects minor clogging. Clogging varies with distance down the wetland cell in response to wastewater loading. It is greatest in the inlet area and least in the outlet. Variability between the systems was large, but representative hydraulic conductivity values for relatively long and narrow cells (length to width ratio of 4 to 1) appear to be about 900 m/day (3,000 ft/day) for the inlet area, 3,000 m/day (10,000 ft/day) near the inlet quarter point, and about 12,000 m/day (40,000 ft/day) for the outlet half of the cell. Additional studies at other sites are needed to determine whether these values are actually typical. Use of 260 m/day (850 ft/day) for design of systems based on TVA guidelines is still considered a conservative, simplified approach with significant advantages and few drawbacks. Since the design will be hydraulically conservative, the approach minimizes the difference in water levels between inlet and outlet for a cell with a flat surface and bottom. If additional flexibility is needed for adapting a system to a particular site, design values could be justified that are an order of magnitude higher (i.e. 2,600 to 3,000 m/day, 8,500 to 10,000 ft/day). Designs should also routinely specify septic tank filters to minimize suspended solids load on the inlet of the wetlands cell.

AB  - This article focuses on the social methods of the Tennessee Valley Authority. The Tennessee Valley Authority was created by the U.S. Congress at the suggestion of the U.S. President to bring about certain developments in the drainage area of the Tennessee river and in adjacent regions similarly placed. It has certain very obvious duties sale of surplus power, the building of dams, and the production of cheap fertilizer. The Tennessee Valley Authority is instructed to make studies, experiments, and demonstrations with the aim of improving social and economic conditions within the area. This is a fairly general instruction, not too well implemented. Some of this work has been of a fairly obvious nature. Soil erosion is destroying the very physical foundation of the rural culture of this region. So one have been promoting soil conservation by example and precept. Forests had been denuded, and are working out an orderly forest policy in cooperation with foresters of the adjoining States and of the National Government. Small mountain farms are not adequate for cash income, and agricultural income should be supplemented by local industries.

AB  - This article focuses on the social-economic development in the Tennessee River Valley. For many reasons the Tennessee Valley was selected as a logical area in which to try out a large-scale planning experiment. When the Tennessee Valley Authority came into existence, there were several specific tasks ahead that had to be done building Norris Dam. A beginning was made there, and, while the construction work is under way, preparations are being made to meet the problems already in existence or created by the construction program itself. Much information is necessary as the basis of intelligent planning for the social-economic development of an area so large as the Tennessee Valley region. In December in the midst of unprecedented unemployment, the Tennessee Valley Authority was able to begin needed surveys and research by use of a personnel made available by funds from the Civil Works Administration. A portion of this personnel was allocated to the compilation of basic social and economic data.

AB  - The reasons for the creation of the Tennessee Valley Authority are found in the social and economic conditions prevalent in large sections of the southeastern the U.S. Though the drainage basin of the Tennessee River has long been recognized as possessing unusual developmental possibilities, the economy of the region has been obviously unsatisfactory. Abandoned mines, depleted forests, eroded soils, and stranded populations testified to the unwise use that had been made of natural resources. The selection of the valley of the Tennessee River as the location of a national experiment in regional planning was the nation's response to a recognition of these conditions. The ultimate objective of the Tennessee Valley Authority program, as defined by Congress, is to promote the economic and social well-being of the people of the region. The methods provided for bringing about these results are stated to be the development of the Tennessee River for navigation, flood control, and the generation of electric power incidental to and consistent with flood control and navigation. Cheaper and more efficient fertilizers are to be developed, proper use is to be found for marginal land, and methods of reforestation are to be worked out.

AB  - As an abstract science, some people may think that they can isolate sociology from other aspects of human activity. In its practical applications, however, such separation never is possible. In almost every case applied sociology will be found to be only one phase of a complex of activity. The sociological component cannot be isolated and treated by itself. It must be considered in relation to the current of events and in relation to all other components. Therefore, the sociologist who pretends to be aware only of his own field in housing, labor relations, population distribution, or any other aspect of the subject, no matter how acute and scholarly he may be, is apt to be a menace rather than a help in a practical situation. Conversely, when any great social project is carried through without clear recognition and provision for the sociological components, as so often has been the case, the results in human waste may be very considerable. A discussion of sociology in the Tennessee Valley Authority, therefore, resolves itself into a discussion of the provisions which are made for analysis and treatment of those factors of the undertaking which are sociological in their nature.

AB  - This article discusses background of the class-rate investigation. The U.S. Interstate Commerce Commission has instituted an investigation of interstate class rates, both intraterritorial and inter territorial, in Official, Southern, Southwestern, and Western Trunk-Line rate territories, which rate groups comprise the area in the United States east of the Rocky Mountains. The class-rate investigation is one of the most far-reaching examinations of freight rates yet announced by the Commission and may result in setting a pattern for fundamental changes in the economy of the South and West. It is therefore worthwhile to examine the events that preceded the announcement of the investigation and the forces that influenced it. The reaction of various groups to the announcement of the investigation is also interesting. Professor Malcolm Keir has written that undue favoritism was given eastern cities by rate adjustments which encourage raw materials to be drawn from outlying regions to the East and finished goods to be returned.

AB  - The article focuses on problems of union relations in public agencies in the U.S. In this brief paper, the author attempts to describe the status of public employee unions, defines the major issues and areas of greatest confusion and suggests the basic principles that may provide a workable approach to problems of union relations in public agencies. Contrary to predictions of some observers, conditions of wartime have brought no lessening of effort on the part of public employees to clarify and advance their status. Public employees, like other groups of citizens, have felt the impact of current trends in the cost of living, the pinch of static wage levels, the unparalleled growth of employee-union participation in the war efforts of private industry, the need for training and the threat of future job insecurity as requirements of war bring new thousands into the public service. Unionism among public employees in the U.S. has increased significantly in the last decade. Much of the discussion of problems of union relations in public agencies fails to recognize this significant growth of unions among public employees.

AB  - The article focuses on the principles of democracy and efficiency embodied in Tennessee Valley Authority (TVA) and the philosophy behind its operation. There is nothing new in the idea that planning is part of the responsibility of democratic government, whether it be done by the people of a city, a state, or a nation. In general, the instrumentalities of democratic planning are of two sorts--first, official agencies functioning within the framework of the local, state, and national governments; and second, unofficial agencies representing some cross section of citizen interest and prepared to bring popular opinion to bear on the legislative and administrative branches. The Tennessee River drainage basin is a completely logical unit of planning in only one respect--the use and control of water. TVA is an instrument of democratic planning that differs in many respects from its predecessors. It is an official agency but its sphere of operations does not coincide with the territory of any unit of government. It is a national agency because only the federal government has been given authority which is broad enough to encompass the multiple problems of an interstate river basin.

AB  - A regional development program will suggest different things to different individuals, and to all it is likely to suggest not a single program but a number of related programs focusing on a common objective. To a staff member of a development agency, a regional development program implies literally scores of individual programs ranging from those involving engineering projects to those basically educational in nature carried out co-operatively with educational and other regional institutions. Since these programs are neither comparable nor amenable to uniform methods of analysis, a complete discussion of criteria for their evaluation cannot be attempted in a paper such as this. Regional development purposes will be defined as a process resulting in a secular growth of regional output or real income. This, of course, is less than a comprehensive definition of regional development as many intangible aspects of development are not susceptible of measurement by a monetary yardstick. This growth can occur autonomously. It may be influenced also by the impact of national economic expansion imparted through the private sector of the economy. A regional development program, therefore, must be distinguished as an influence exogenous to the normal functioning of the private economy. For the purpose of this discussion, a regional development program will be defined as a public undertaking, most likely a governmental undertaking, one of whose primary objectives is to influence the underlying factors affecting regional output.

AB  - "The Committee on Public Finance," a collaborative writing group consisting of sixty-six professors teaching at colleges and universities, have produced the latest in the long series of text books in public finance. Pooling their scholarship and teaching experience they have sought to meet the wants and needs of public finance instructors for a broad and comprehensive text "implicating the larger problems of freedom, justice, and the nature of individual and social well-being." The strong points of the book are its scope and organization which seek to fit the various phases of public finance into a single and unified process. The Committee deserves congratulations for its efforts to show the process of financing governments as one which involves economics, accounting, political science, administration, law, history, and sociology. The new text should help students to appreciate the complex and growing place of public finance in modern society, and instill a greater concern for the orderly administration of the public sector of the economy. It can make no greater contribution.

A sample of 'typical' articles were searched in each index, and all the indexing terms were listed for each article in each index. A comparison of these displays 'shows some surprising differences in their selection of index terms and raises questions about the validity of rules for subject indexing.'

AB  - This article discusses Tennessee Valley Authority's (TVA) approach to sub-regional development. Tributary area development is essentially an approach which utilizes local interest and initiative, both governmental and private citizen, to carry forward a comprehensive resource development effort directed at uplifting the social and economic well-being of residents of sub-regions of the Tennessee Valley. The program concentrates on areas which have lagged behind the development pace of the rest of the Tennessee Valley, and TVA's role within this framework is to provide assistance to tributary organizations by building on and learning from experiences in earlier programs that were Valley-wide in scope. The purpose of this paper is to describe TVA's tributary area development program, review a few of its accomplishments, and suggest some problem areas for further consideration and research. TVA's first effort at working in the development of a multicounty tributary area began about 1939 in the Chestuee watershed in southeastern Tennessee.

AB  - The article discusses the proper role of the U.S. Federal regulation with respect to the transportation of dry bulk commodities by water and rail. The transportation of dry bulk commodities is very important business for both rail and water carriers, and present trends are in the direction of increased proportions of this traffic. Movement in bulk saves expensive packaging and handling and new types of rail cars and barges are being developed that will bring about a greater variety and larger volumes of bulk shipments. The role of the Federal regulations in the transportation of bulk dry commodities has been a bone of contention ever since Part III, extending the regulation of water transportation, was added to the U.S. Interstate Commerce Act in 1940 and dry bulk commodities were exempted in section 303(b). There have been many efforts to repeal or modify the exemption or to extend it to other forms of transportation, none of which has resulted in any significant changes in the scheme of Federal regulation. The first session of the 90th U.S. Congress, however, saw an ingenious new move by the water carriers to modernize and rationalize the exemption and a predictable countermove by the rail carriers to obtain a similar exemption.

AB  - The author reflects on the single resource productive objectives of the educational institutions, professional organizations, and action agencies. He stresses that resource objectives were met in the past because the total resource demands were low, and the land and water base were large. He also argues that the growing frequency of works caused the resource objectives to collide and there is a need for a change in management approaches and practices to be able to produce and optimize benefits.

AB  - This article discusses the implications of Public Land Law Review Commission (PLLRC) tax tecommendations for federal hydro projects and power facilities in the U.S. The PLLRC in the U.S. was established by a special act of Congress on September 19, 1964. It was directed to make a comprehensive review of die public land laws, rules and regulations, to study the policies and practices of the federal agencies charged with administrative jurisdiction over lands, and to recommend necessary revisions. The Commission's landmark report included a discussion of the problem of revenue sharing and payments in lieu of taxes on federal property, together with three related recommendations. These recommendations are summarized as follows: Number 101: The federal government should make payments to compensate state and local governments for the tax immunity of federal lands. Number Payments in lieu of taxes should be made to state governments, but such payments should not attempt to provide full equivalency with payments that would be received if the property were in private ownership.

AB  - The metabolism of glycolate by Eurasian watermilfoil (<em>Myriophyllum spicatum</em> L.), a submersed angiosperm, was studied by feeding radioactive glycolate and glyoxylate and by analysis of glycolate and glycolic acid oxidase. Evidence for operation of the glycolate pathway is given. Glycolic acid oxidase occurs at levels comparable to amounts in species showing photorespiration. This species has a high affinity for CO2 and a possible mechanism for it is described. [ABSTRACT FROM AUTHOR]

AB  - The new Tennessee act addresses head-on a vexing problem common to most new town developments: how to provide meaningful participation for new community residents in the planning, development and administration of new towns and yet reserve to developers the planning autonomy they desire — and need if they are to risk the large sums of money required to undertake such projects. The act attempts to solve the problem of citizen participation in new community development and administration by bringing state government and potential new town developers into a cooperative relationship, which provides for the early municipal incorporation of state-approved new towns in a manner which does not unduly threaten the developer's interests. In addition to questions of local governmental control, the creation of new towns involves such area matters as economic development, population settlement and environmental protection. The New Community Development Act assigns responsibility for policy making to the state through creation of the Tennessee Community Development Board.

AB  - This article attempts to measure the success of the trade readjustment assistance (TRA) provisions by examining the effects of the benefits on displaced workers in the U.S. TRA benefits did prolong the interval of unemployment/nonparticipation, and did not promote a wage advantage in the new job. Assuming that the objective of trade readjustment benefits is to accomplish reemployment at the lowest possible cost to the individual, then the system must be judged a failure in this case. The increased interval of nonwork might be caused not by improved job search behavior but by a preference for readjustment benefits plus leisure over their best employment opportunity. This behavior was partially evident among females who combined long intervals of nonemployment with the greatest ultimate wage losses. These subjective impressions are confirmed by the fact that most persons electing trade readjustment assistance's training did so after first exhausting about 50 weeks of unemployment benefits. It is apparent that improved administrative control, coordination with other public agencies, counseling, job development, and outreach efforts could have been of economic benefit to recipients of adjustment assistance.

AB  - This article addresses the problems, difficulties, pitfalls, and drawbacks in inventory management, from teaching and research in academia to applying, installing, and successfully using inventory systems in practice. Some guidelines and suggestions are offered to students, teachers, analysts, users and managers of inventory systems. Several of these guidelines are not uniquely associated with inventory management but apply equally well to the entire OR/MS area. This article is to some extent based on the discussions of a symposium with the same title that the authors organized and participated in during the 11th National Meeting of the American Institute for Decision Sciences, New Orleans, November 1979.

AB  - The article presents the results of a cluster analysis which identified four consumer segments in the solar water heater market in the U.S. The project involves the design, installation. certification, and low-interest financing of solar water heaters to replace electrical-resistance water heaters. Four market segments emerged from cluster analysis: the Aspirants, the Established, the Comfortable, and the Affluent. Minorities were conspicuous by their absence from all four groups; each segment was at least 96% white.

AB  - Cereal yield increases have been achieved in recent solution culture studies by supplementing nitrate with limited levels of ammonium where secondary effects on factors such as pH and micronutrient availability in the solution were controlled. In these studies, ammonium rates were controlled within relatively narrow limits, of growth stimulation and excess ammonium. In contrast, NFDC greenhouse studies with spring wheat (Triticum aestivum L.) and grain sorghum [Sorghum bicolor (L.) MoenchJ indicate that a wider range of supplemental ammonium rates can be applied with a basal nitrate rate in soil without causing yield reductions, probably because ammonium movement to roots is slower in soils than in solution culture. Also, ammonium/nitrate ratios required to maximize wheat and grain sorghum yields in the greenhouse were higher than ratios typically observed in field soils during periods of primary N uptake, suggesting a potential for yield increases in the field. Limitations for achieving potential cereal yield increases with higher ammonium/nitrate ratios are (i) inadequate characterization of optimum ammonium/nitrate ratios in relation to stage of plant growth, (ii) inadequate technology and practices for simultaneously controlling ammonium/nitrate ratios throughout most of the growing season and providing adequate positional availability of ammonium to roots, and (iii) inadequate determination and exploitation of genetic variability regarding yield response to ammonium/nitrate ratios.

AB  - Reviews the book, A Guide for Therapists and Patients to Short-Term Psychotherapy by E. Lakin Phillips (1985). As the title clearly states, this is a book for patients as well as for their would-be therapists. However, rather than telling patients how they should behave in the therapeutic process--that is, how to play by therapists' rules--Phillips candidly orients them to what they should expect from the therapy enterprise. He proposes that they make a trial visit to a therapist and suggests a wide range of professionals and referral mechanisms that they can use to start their search for better living. Phillips also offers an enlightened understanding to professional therapists from all disciplines. This book should be required reading in clinical and counseling psychology internships, psychiatric residencies, schools of social work, and all of the other programs that are producing the new generation of psychotherapists. There is a superb overview of the history of both psychodynamic and behavioral psychotherapy and the evolution of the major theoretical and procedural varieties of treatment that constitute the field.

AB  - This article develops and applies a simple empirical methodology based on the location quotient to identify the existence, direction, and nature of service trade within a hierarchy of places. Our methodology rests upon the well-known foundations of central place theory set forth by Christaller (1966). It assumes a hierarchy of places in which the market area of each place is nested in the market area of the next highest order place, an extent of trade within the hierarchy that is dominated by agglomerative economies, and a flow of agglomerative services from higher to lower levels (Christaller 1966). We further presume that profit seeking entrepreneurs will seek out and find most profitable local and export activities. Unlike the models of the urban hierarchy that constrain service sector activities to some mix of residentiary production and sales in the immediate hinterland, our model of basic imports and exports allows basic service activities to arise throughout the hierarchy. Our model empirically distinguishes between those exports that originate in a higher order place and flow only to lower order places in the appropriate hinterland and those exports that cross hinterland borders.

AB  - Degradation of dicyandiamide (DCD) was assayed in laboratory studies at 8, 15, and 22 C in a Decatur silt loam and in a Norfolk loamy sand. Dicyandiamide was very short lived at 22 C, with half‐lives of 7.4 and 14.7 days in the Decatur and Norfolk soils, respectively. In the Norfolk soil at 8 C, half‐life increased to 52.2 days. In a nitrificaton study of both soils at 22 C, 80 mg (NH4)2SO4‐N kg‐1 of soil was applied with 20 mg DCD‐N kg‐1 of soil and 100 mg kg‐1 (NH4)2S04‐N was added with 5% nitrapyrin. Distinct lag phases preceded zero order nitrification with the inhibitor treatments. Lag periods were 2 and 2.6 times the half life of DCD in the degradation study for Decatur and Norfolk soils, respectively. Like most nitrification inhibitors, the effectiveness of DCD decreases with increasing temperature. In the Norfolk loamy sand, nitrification inhibition by DCD was equal to nitrapyrin for up to 42 days, but in Decatur silt loam, DCD was less potent to nitrapyrin as a nitrification inhibitor.

AB  - One-year-old half-sib loblolly pine (<em>Pinus taeda</em> L.) seedling were planted in a sandy loam soil having approximately 15 or 35 mg kg-1 of exchangeable Mg and were exposed to subambient, ambient, or twice ambient (0.02, 0.05, or 0.09 μl O3 l-1, respectively) concentrations of O3 in open-top chambers from April to October 1988. The cold hardiness of seedling was tested on October 24, January 24,and March 21 by subjecting needle samples from the first and last growth flush to temperatures of -5,-10,-15, and -20 °C and determining relative electrical conductivity of the diffusate. Seedlings exposed to twice ambient O3 levels during the growing season were less hardened in early autumn and spring than seedlings exposed to ambient or subambient levels of O3 suggesting that O3 affects the plant's hardening and dehardening processes. Ozone and soil Mg treatments had no significant effects on visible injury of shoots following freezing treatments, nor were any visible symptoms of injury due to O3 evident during the study. Water potential components of excised shoots were estimated using pressure volume analysis. Osmotic potentials became more negative over the dormant peroid, suggesting that solutes had accumulated in the cells as seedling hardened. Seedlings grown in high Mg soil had less negative osmotic potentials in January and March than those grown in Low Mg soil, suggesting that seedling in high Mg soil were more susceptible to cold temperatures,due to greater physiological activity.

Rae; see record [rid]1979-26203-001[/rid]), no gender differences remained on any of the measures after the effects of salary, age, education, and job classification had been taken into account. Findings replicated earlier results showing depressed males to have greater difficulty with concentration and motivation than depressed females. MMPI sex-based T-scores may overcorrect for sex differences in raw scores. Possible explanations for the findings include a general improvement in women's well-being associated with changes in social conditions such as employment or a self-selection bias in this sample.

AB  - Extraction efficiency for metribuzin [4‐amino‐6‐(1,1‐dimethyl‐ethy 1)‐3‐(methylthio)‐l,2,4‐triazin‐5(4H)‐one] from soil was evaluated using four solutions of methanol:water at ratios of 1:1, 7:3, 4:1, and 1:0 v/v. Two concentrations of metribuzin (O.216 and 2.44 ug/ g soil, unlabeled and I4C‐metribuzin, respectively) were added to surface and subsurface samples of a Dundee silt loam soil. Although the differences in extraction efficiencies were slight due to differences in methanol:water ratios, the metribuzin recovery varied with soil depth. Less metribuzin was recovered from surface soil extracted with 1:1 and 1:0 methanol:water solutions when compared to 7:3 and 4:1 solutions (80 and 81% vs 89 and 88% recoveries, respectively). About equal quantities, 81 to 85%, were recovered from the subsurface soil. Three extraction shaking times (0.5 h followed by another 0.5 h; 4 h:4 h; and 24 h:24 h) were also evaluated using the 4:1 extractant. No recovery differences were observed between the 0.5 h and 4 h shaking times. However, significantly higher recoveries occurred in both the surface and subsurface soil with 24 h shaking. The efficiency of this method was also determined on Eustis loamy sand, Sharkey clay, and Dorovan muck soils of diverse physical and chemical properties. The 4:1 extracting solution consistently yielded among the highest metribuzin recovery (74 to 97%) from the four soil types, and two soil depths of a Dundee soil. [ABSTRACT FROM AUTHOR]

AB  - Loblolly pine (<em>Pinus taeda</em> L.) seedlings of five half-sib families were grown for 3 yr in the field in open-top chambers. The seedlings were fumigated during the growing seasons (approximately April--October) with ozone at the following target levels: subambient (CF), ambient (AMB), and ambient +60 ppb (AMB +). At the end of the three growing seasons, no significant ozone effects on diameter, height or total biomass of the seedlings were detected, and no statistically significant ozone-family interactions were detected. Analysis of growth trends suggest that drought during the second and third growing seasons may have interacted with the ozone treatments. The importance of long-term studies under realistic field conditions is discussed. [ABSTRACT FROM AUTHOR]

N2  - Quasi-experimental techniques were developed to provide decision-making tools for documenting the impacts of developmental highways in rural areas. Regression discontinuity analysis (RDA) with limited observations was used to compare economic changes in highway counties to those in adjacent and non-adjacent control counties. The RDA models found statistically significant changes in population, per capita income, and taxable sales related to highway development. The study found that some counties benefitted from developmental highways, some were unchanged, while some experienced economic decline. RDA models with adjacent controls had better explanatory powers while those with non-adjacent controls were more sensitive to highway-related changes in economic activity. When significant non-highway activities were presented, adjacent control models may have understated highway-related impacts, while non-adjacent control models may have overstated these impacts. Arguments for using adjacent and non-adjacent experimental designs are discussed.

AB  - Two-year-old blue tilapia, <em>Oreochromis aureus</em> (Steindachner), were stocked into five replicate breeding hapas (1.2 m x 1.2 m x 2.7 m) at a density of six males and six females per hapa. At stocking, males and females averaged 415 and 225g respectively. During the 50-day trial (July-August), 62900 seed (eggs and sac-fry) representing 78 spawns, were collected from 30 females. In comparative treatments, prestocking surgical removal of the male s maxillary bone did not influence hatchery productivity. However, removal ofthe female's maxillary bone significantly reduced frequency of repeat spawning and clutch size (P < 0.05). Removal of the maxillary bone also influenced weight gain of broodstock. It is hypothesized that these significant responses were due to the surgical removal of the maxillary bone and the subsequent breakdown in dominance hierarchies. [ABSTRACT FROM AUTHOR]

AB  - Assessments of ozone sensitivity in tree species have been based primarily on studies of seedlings without any knowledge of the similarities between seedling and mature tree responses. To determine if seedlings and trees responded similarly to ozone, 2-yr-old seedlings and 30-yr-old trees of Quercus rubra L. were fumigated with subambient, ambient and twice-ambient ozone for one growing season (cumulative doses of 18, 45 and 87 ppm h[sup-1], respectively). Carboxylation efficiency, apparent quantum yield and light-saturated net photosynthesis of leaves from the lower canopy of the 30-yr-old trees were reduced by ambient and twice-ambient ozone treatment. However, physiological characteristics of leaves from the upper canopy of trees showed no signs of ozone injury. Canopy leaf dry weight of trees was reduced by the twice-ambient ozone treatment through reductions in leaf area rather than specific leaf weight, but bole diameter and branch growth of trees were unaffected by ozone treatment. In contrast, ozone did not influence leaf physiology of second Hush leaves, stem diameter, and height and biomass growth of 2-yr-old seedlings. These results indicate that for deciduous hardwood species, studies of seedlings may underestimate the ozone sensitivity of larger and more physiologically mature trees. For large trees with developed canopies, leaf position within the canopy may influence the sensitivity of physiological processes to ozone. [ABSTRACT FROM AUTHOR]

AB  - The Tennessee Valley Authority, a federal corporation established by Congress in 1933, is charged with the integrated regional development of the Tennessee Valley's resources, including flood control, navigation, reforestation and proper use of marginal lands, electricity generation, and agricultural and economic development. TVA's early leaders, especially David E. Lilienthal and Gordon R. Clapp, articulated a doctrine of "grass roots democracy" and "decentralization" that protected TAV from rival federal bureaucracies and provided greater flexibility and freedom in carrying out TAV's multi-purpose mission. This doctrine also led to innovations in the professionalization of TAV's highly skilled and diverse workforce. Clapp, a recognized leader in public administration, promoted employee initiatives, easy access to top management, multi-disciplinary teamwork, labor/management collaboration, and partnerships with states and localities that took account of local needs and values. The development of joint cooperative councils and conferences, along with other initiatives, were visible manifestations of this "democratic method of administration." [ABSTRACT FROM AUTHOR]

AB  - Evaluating the long‐term environmental effects of controlled‐availability nitrogen (N) fertilizers is best done with 15N‐labeled materials. Simple bench‐scale methods not requiring elaborate apparatus are described for synthesizing 15N‐enriched isobutylidene diurea (IBDU) and oxamide suitable for such purpose. IBDU is prepared by reacting 15N‐labeled urea with isobutyr‐aldehyde. Oxamide is made by reacting 15N‐labeled ammonia (NH3) with ethyl oxamate. No specific method but a general description is provided for synthesizing ureaform because the chemical composition of the family of polymers known as ureaform varies with reactant ratios and reaction conditions.

AB  - Chemical measurements made during an air pollution event in Atlanta, GA have been compared with results from several photochemical simulations. Measurements included O 3 , primary reactive organic gases (ROG), aldehydes, PAN, total reactive nitrogen (NO y ) and H 2 O 2 , with vertical profiles for primary ROG. Photochemical models using two different chemical representations and a range of assumptions about winds, vertical mixing and emissions were used to simulate the event. Results show that assumptions about vertical mixing can cause a variation in simulated surface concentrations of primary hydrocarbons of a factor of two or more. A tendency to underestimate isoprene was found in comparison with measured vertical profiles. The models tend to overestimate concentrations of HCHO, H202 and PAN in comparison with measurements. Peak O 3 and concurrent NO y from helicopter measurements was used as a basis for evaluating individual model scenarios. Scenarios were developed with different O3 NOx- ROG sensitivity, but only the NO x - sensitive scenarios are consistent with measured O 3 , NO y and isoprene. [ABSTRACT FROM AUTHOR]

AB  - The article evaluates the readiness of a major U.S. Southeastern hospital toward the implementation of a total quality management (TQM) process. Hospitals around the country are being challenged to implement TQM processes by the Joint Commission on Accreditation of Health Care Organizations and customers. Research and experience in quality management have identified seven key characteristics critical to organizations striving to implement excellent quality processes: influence, responsibility/autonomy, satisfaction, desire to change, common vision/benchmarking, innovativeness, and teamwork. Operational performance measures should support TQM. Labor-efficient processes which do not meet the customer's needs will not enhance quality or market share. Quality outputs such as customer satisfaction or low infection rates may be more appropriate measures. Nevertheless, with a focus on TQM many organizations have found that labor efficiency also improves. If top management does not provide sufficient support, the TQM process is likely to be impeded. As in other organizations, hospital employees must have input into the design and implementation of the TQM process. Key groups must be formed to determine the organization's approach to TQM. These core groups will lay the foundation for a successful quality initiative.

AB  - A two-component model of growth and maintenance respiration is used to study the response of northern red oak (<em>Quercus rubra</em> L.) seedlings and 32-year-old trees to sub-ambient (10/μmol h; cumulative dose based on 7 h daily mean), ambient (43 μmol h), and twice-ambient (85/μmol h) ozone. The relative growth rates (RGR) of leaves sampled from seedlings and trees were similar across treatments, as were specific leaf respiration rates (SRR). Growth coefficients estimated from the SRR versus RGR relationship averaged 25.3mol CO2 kg-1 leaf dry mass produced for seedlings and 21.5mol kg-1 for trees. Maintenance coefficients ranged from 0.89 to 1.07 mol CO2 kg-1 leaf dry mass d-1 for seedlings and from 0.64 to 0-84 mol kg-1 d-1 for trees. Neither coefficient was affected by ozone. Leaves sampled throughout the growing season also showed little response of respiration to ozone. This occurred despite a 30% reduction in net photosynthesis for trees grown at twice-ambient ozone. These results suggest that growth and maintenance respiration in young northern red oak leaves are not affected by ozone and that in older leaves injury can occur without a parallel increase in so-called 'maintenance' respiration.

AB  - Changing regulatory incentives in the electric power industry are forcing utility transmission and distribution (T&D) planners to change their approach to investment planning. To minimize the risk of over-investment, utilities need to perform an analysis of system capacity limitations which goes beyond traditional peak load and temperature planning, and routinely consider a variety of alternate incremental capacity expansion measures. Existing engineering tools are inadequate for determining the potential cost advantage of deferring an expansion, or for evaluating the net benefits of distributed resources (DR). Conversely, integrated resource planning (IRP) tools often underestimate or ignore important DR siting restrictions and operational impacts. This paper describes a process to identify T&D capacity constraints, evaluate conventional and alternative capacity additions and DR applications, and explore the risk of operating beyond limits imposed by current reliability practices. The process uses hourly load-flow information to quantify the total annual energy and customer outage costs. The same information is used to build plans incorporating and dispatching DR where they have the greatest impact on minimizing expansion needs. A detailed case study demonstrates the process by quantifying the economic benefits of deferring an expansion with a do-nothing plan. The study reveals both unforeseen advantages and impracticalities of DR use. [ABSTRACT FROM AUTHOR]

AB  - A nighttime warming experiment is proposed. Over the last four decades a significant rise in nighttime minimum temperature has been determined from analysis of meteorological records from a global distribution of locations. The experiment involves nighttime deployment of infrared (IR) reflecting curtains around four sides of a forest canopy and across the top of the forest to mimic the top-down warming effect of cloud cover. The curtains are deployed with cable and pulley systems mounted on a tower and scaffolding structure built around the selected forest site. The trunk space is not enclosed except as an optional manipulation. The curtains reflect long-wave radiation emitted from the forest and ground back into the forest warming the trees, litter, and soil. Excellent infrared reflection can be obtained with commercially available fabrics that have aluminum foil bonded to one side. A canopy warming of 3 to 5 °C is expected on cloudless nights, and on cloudy nights, a warming of 1 to 3 °C is anticipated relative to a control plot. The curtains are withdrawn by computer control during the day and also at night during periods with precipitation or excessive wind. Examples of hypothesized ecosystem responses to nighttime warming include: (1) increase in tree maintenance respiration (decreasing carbon reserves and ultimately tree growth), (2) increase in the length of the growing season (increasing growth), (3) increase in soil respiration, (4) increase in litter decomposition, (5) increase in mineralization of N and other nutrients from soil organic matter, (6) increase in nutrient uptake (increasing growth), and (7) increase in N immobilization in litter. Hypothesis 1 has the opposite consequence for tree growth to Hypotheses 2 and 6, and thus opposite consequences for the feedback regulation that vegetation has on net greenhouse gas releases to the atmosphere. If Hypothesis 1 is dominant, warming could lead to more warming from the additional CO2 emissions. Site-specific meteorological, ecophysiological, and phenological measurements are obtained in the warming treatment and in a carefully selected control plot to investigate site-specific hypotheses. Measurements made on both plots for a baseline period and during the period of curtain deployment provide data to test the hypotheses statistically by the “before-after-control-impact” method applicable to unreplicated experiments. The enclosure has a modular design that can be adapted and combined with other forest-scale manipulation experiments such as free air CO2 enrichment and throughfall displacement.

AB  - Species recovery efforts generally focus on in situ actions such as habitat protection. However, captive breeding can also provide critical life history information, as well as helping supplement existing or restoring extirpated populations. We have successfully propagated nine species in captivity, including blackside dace, spotfin chubs, bloodfin darters, and boulder darters. Threatened blackside dace, Phoxinus cumberlandensis, were induced to spawn in laboratory aquaria by exposing them to milt from a reproductively mature male stoneroller, Campostoma anomalum or river chub, Nocomis micropogon. The latter are nest-building minnows, with which Phoxinus may spawn in nature. Eggs are broadcast among gravel and pebbles. Blackside dace individuals reared in captivity were used for translocation. Threatened spotfin chubs, Cyprinella monacha, fractional crevice spawners, deposited eggs in laboratory aquaria in the spaces created between stacks of ceramic tiles. Captively produced spotfin chubs were used as part of a larger stream restoration and fish reintroduction project in the Great Smoky Mountains National Park. The bloodfin darter, Etheostoma sanguifluum, was first used as a surrogate to develop techniques for spawning a closely related species, the endangered boulder darter, E. wapiti. Both darter species mated in a wedge created between two ceramic tiles. Our efforts have had variable but generally high success, with survival rates of 50-90% of eggs deposited. Captive production of nongame fishes can aid recovery of rare species or populations, aid in watershed restoration, and can help to refine water quality standards. In addition, captive breeding allows discovery of important behavioral or life history characteristics that may constrain reproduction of rare species in altered natural habitats.

AB  - This report summarizes a PM[sub2.5]/PM[sub10] particulate matter data set consisting of 861 PM[sub2.5]/PM[sub10] sample pairs collected with dichotomous samplers by the Tennessee Valley Authority (TVA) from 1982 to 1991. Eight monitoring stations, ranging from urban-industrial to rural-background, were operated across three east-central U.S. states. Annual average PM[sub2.5] concentrations ranged from 12.6 to 21.3 micrograms per cubic meter (µg/m³), with an overall mean of 15.7 µg/m³ Likewise, annual average PM[sub10] concentrations ranged from 17.8 to 33.7 µg/m³, with an overall mean of 23.7 µg/m³ High summer-low winter seasonality was evident, particularly for PM[sub2.5], with the highest monthly PM[sub2.5] and PM[sub10] concentrations in August (26.4 and 37.5 µg/m³, respectively) and the lowest in February (9.9 and 15.3 µg/m³, respectively). A strong association (r²= 0.84) was found between PM[sub2.5] and PM[sub10] mass with PM[sub2.5] mass contributing, on average, 67% of PM[sub10] mass. Applying TVA's PM[sub2.5]/PM[sub10] ratio to recent (1993-1995) regional high-volume PM[sub10] Aerometric Information Retrieval System (AIRS) data for the east-central United States suggests that as many as 80% of monitored counties would have equaled or exceeded the level of the new annual PM[sub2.5] metric of 15 µg/m³ A decline in average PM[sub2.5] mass on the order of 3-5 µg/m³ from 1982 through 1991 is  also suggested. Daily PM[sub2.5] mass appears to be reasonably well associated (r = 0.47) with maximum hourly ozone during the warmer months (spring through fall). Sulfate compounds comprise a major portion of the measured PM[sub2.5] mass, with that fraction being highest in the summer months. Viewed collectively, these data suggest that although compliance with the annual and 24-hr PM[sub10] and 24-hr PM[sub2.5] metrics should prove readily attainable, the annual PM[sub2.5]...

AB  - Airborne measurements were made of gaseous and particulate species in the plume of a large coal-fired power plant after flue gas desulfurization (FGD) controls were installed. These measurements were compared with measurements made before the controls were installed. The light scattering and number and volume distributions of plume excess particles were determined by nephelometry and optical particle counting techniques. The plume impact based on optical techniques was much lower than that observed in earlier measurements. Indeed, plume excess volumes as a function of particle size were of the same magnitude as the variability of the background volume distribution. In situ excess plume scattering actually decreased with distance from the source, in contrast to pre-FGD conditions. The upper limit for the dry rate of SO[sub2]-to-SO[sub4]&sup2-; conversion was estimated from plume excess volume measurements to be about 4% hr[sup-14]. This is slightly greater than the upper limit, 3.5% hr[sup-1], estimated by earlier researchers, but the same as that estimated using the present technique with the earlier data. The cross-plume profile of volume suggests SO[sub2]-to-SO[sub4]&sup2-; conversion is highest at the plume edges. The greatest benefit of SO[sub2] reduction on plume excess volume and visibility appears to occur far downwind of the source. [ABSTRACT FROM AUTHOR]

AB  - Fine particles in the atmosphere have elicited new national ambient air quality standards (NAAQS) because of their potential role in health effects and visibility-reducing haze. Since April 1997, Tennessee Valley Authority (TVA) has measured fine particles (PM[sub2.5]) in the Tennessee Valley region using prototype Federal Reference Method (FRM) samplers, and results indicate that the new NAAQS annual standard will be difficult to meet in this region. The composition of many of these fine particle samples has been determined using analytical methods for elements, soluble ions, and organic and elemental carbon. The results indicate that about one-third of the measured mass is SO[sub4][sup-2], one-third is organic aerosol, and the remainder is other materials. The fraction of SO[sub4][sup-2] is highest at rural sites and during summer conditions, with greater proportions of organic aerosol in urban areas throughout the year. Additional measurements of fine particle mass and composition have been made to obtain the short-term variability of fine mass as it pertains to human exposure. Measurements to account for semi-volatile constituents of fine mass (nitrates, semi-volatile organics) indicate that the FRM may significantly under-measure organic constituents. The potentially controllable anthropogenic fraction of organic aerosols is still largely unknown. [ABSTRACT FROM AUTHOR]

AB  - Epidemiology studies relating health effects to ambient levels of ozone and fine particles have led to the modification of standards in the United States for these pollutants (substitution of an 8-h standard for ozone at 80 ppbv, and addition of 24-h and annual standards for fine particles). The interrelationships of these pollutants in the atmosphere suggest the need for an integrated, science-based strategy for their control. Secondary ozone formation has been controlled through emission controls on VOC and NOx precursors. Fine particles are secondary products largely resulting from the oxidation of precursors (SO2, NOx, and VOCs). The key intermediates in both types of secondary process are free radical species and the photochemically labile compounds that produce them in the atmosphere. However, due to the complex and nonlinear nature of the processes, reductions in precursors may lead to unexpected changes in ozone and fine particle formation rates. For example, reduction in NOx emissions may reduce ozone and nitric acid levels, but lead also to increased rates of sulfate formation in clouds and increased ammonia availability for neutralization of acidic sulfate aerosols. Reductions of SO2 may reduce aerosol sulfate levels in the summer, but have no effect in other seasons. Reductions in VOCs may reduce ozone levels in urban core areas, but not elsewhere. An integrated, regionally and seasonally specific, emission reduction strategy is needed to cost-effectively reduce both ozone and fine particle levels. [ABSTRACT FROM AUTHOR]

AB  - The rate of conversion of SO[sub2] to SO[sub4, sup2-] was re-estimated from measurements made in the plume of the Cumberland power plant, located on the Cumberland River in north-central Tennessee, after installation of flue gas desulfurization (FGD) scrubbers for SO[sub2] removal in 1994. The ratio of SO[sub2] to NO[suby] emissions into the plume has been reduced to ∼0.1, compared with a prescrubber value of ∼2. To determine whether the SO[sub2] emissions reduction has correspondingly reduced plume-generated particulate SO[sub4, sup2-] production, we have compared the rates of conversion before and after scrubber installation. The prescrubber estimates were developed from measurements made during the Tennessee Plume Study conducted in the late 1970s. The postscrubber estimates are based upon two series of research flights in the summers of 1998 and 1999. During two of these flights, the Cumberland plume did not mix with adjacent power plant plumes, enabling rate constants for conversion to be estimated from samples taken in the plume at three downwind distances. Dry deposition losses and the fact the fact that SO[sub2] is no longer in large excess compared with SO[sub4, sup2-] have been taken into account, and an upper limit for the conversion rate constant was re-estimated based on plume excess aerosol volume. The estimated upper limit values are 0.069 hr[sup-1] and 0.034 hr[sup-1] for the 1998 and 1999 data, respectively. The 1999 rate is comparable with earlier values for nonscrubbed plumes, and although the 1998 upper limit value is higher than expected, these estimates do not provide strong evidence for deviation from a linear relationship between SO[sub2] emissions and SO[sub4, sup2-] formation.

AB  - The high-volume Brigham Young University organic sampling system with a particle concentrator (PC-BOSS) has been field evaluated for the determination of airborne fine particulate matter including semivolatile chemical species during 3 intensive sampling programs in 1997: Tennessee Valley Authority (TVA), Lawrence County, TN; Riverside, CA; and Provo, UT. The PC-BOSS precision was tested using 2 collocated PC-BOSS samplers. In addition, the PC-BOSS results were compared with results from a prototype PM[sub 2.5] U.S. EPA federal reference method (FRM sampler), a filter pack sampler (quartz and charcoal sorbent filters), the BIG BOSS, an annular denuder sampler, and the ChemSpec sampler for the determination of major fine particulate species. Fine particulate mass, sulfate, nitrate, and organic carbonaceous material (OC) determined by 2 PC-BOSS samplers agreed within ±10%. Possibly due to absorption of SO[sub 2] by a quartz filter, the sulfate concentrations determined by the filter pack sampler and the BIG BOSS were higher (by 10 ± 3%) than concentrations obtained with the other samplers. No absorption of SO[sub 2](g) by the quartz filters of the PC-BOSS occurred due to the high efficiency (>99%) of its denuder. The PC-BOSS, annular denuder, and ChemSpec samplers agreed with each other (to within ±0.5 μg/m[sup 3], ±17%, with no bias) for the determination of fine particulate nitrate concentrations, including volatilization losses. The prototype PM[sub 2.5] FRM sampler collected only particle-retained nonvolatile mass. The mass concentrations determined by the PM[sub 2.5] FRM agreed with those collected by the post-denuder Teflon filters of the PC-BOSS (to within ±1.1 μg/m[sup 3], ±10%, with no bias). The overall loss of material from particles and the resultant underestimation of the particulate mass concentrations by the PM[sub 2.5] FRM depended on the fine particle composition and the ambient temperature.

AB  - Improper disposal practices of the once widely used short-chained chlorinated aliphatics have made them a major component of groundwater contamination. Historically, pump and treat technology has been implemented to remediate and contain such aquifer water. After being pumped to the surface, the water is frequently treated with stripper technology. As a result, there is a high volume, low concentration contaminated air stream to either be directly emitted or treated prior to release in an effort to meet regulatory compliance. This work studied the feasibility of using biofiltration technology to remediate trichloroethylene (TCE) contaminated air streams. Furthermore, work focused on operational schemes that influenced the TCE degradation potential within the system. The bench-scale biofilter system contained 42 l of organic packing material and was inoculated with a propane-oxidizing microbial consortium. Propane, the primary substrate, and TCE were introduced into the biofilter in two distinct modes. Initially, TCE and propane were both continuously added to the biofilter system. The maximum TCE degradation observed under this continuous feeding scheme was 25%. Secondly, the TCE and propane were alternately pulsed or cycled in a step-wise fashion into the biofilter system. Under this operating environment, greater than 98% removal of TCE from the air stream was achieved. [Copyright &y& Elsevier]

AB  - Continuous measurements were taken during a 22-day campaign held in the summer of 2000 at a site close to the Great Smoky Mountains National Park in eastern Tennessee. The campaign was conducted to investigate the relationships between ultrafine/fine particles and gaseous species observed. A varimax-rotation factor analysis was performed to explore the relationship of the fine and ultrafine particle number concentrations, the gaseous species concentration, the mean wind speed, and the solar radiation. A 6-factor model was found to best resolve 79.7% of the variability embedded in the data. The model suggests that 31.4% of the data variability could be explained by ultrafine particles (the diameters smaller than or equal to 100 nm). It was difficult to label this factor without chemistry information of the ultrafine particles. However, no gas species were loaded on Factor 1 indicating the ultrafine particles observed in this study were not associated with primary source emissions. The decoupling of the ultrafine particles from the fine particles also implies that the former ones might have been produced and transported to the site by separated mechanisms from those of fine particles. The second factor included the PM2.5 mass concentration and the number concentrations of particles in the diameter range of 101–400 nm. The loading pattern on Factor 2 led to the conclusion that this factor was contributed by regional transport. The third factor includes CO, NO2, reactive odd nitrogen (NOy), and SO2 that were contributed by primary source emissions. The mean wind speed and ozone were loaded in Factor 4 that was labeled as ozone transport. Identification of this factor led to an observation that ozone transport to the site was essentially decoupled from the regional transport factor of fine particles (i.e., Factor 2). Solar radiation was singly included in the fifth factor indicating this is a unique factor. The quality of NO data was marginal and the variable was distilled by the model into Factor 6. A multiple regression analysis further indicated that PM2.5 mass concentration was best explained by CO, O3, and number concentrations of particles in the diameter range between 0.1 and 0.4 μm. We also identified two unique events during the campaign in which the number concentrations of 31–51 nm particles dramatically increased by a factor of 10 in 30 min, reaching 40,000 cm−3 and lasting for a couple of hours. Particles in the size range just below and above those in the 31–51 nm diameter range also exhibited increases during these events, but the changes were much less dramatic. [Copyright &y& Elsevier]

AB  - A brief historical summary of developments in a select few areas of atmospheric measurements is given to illustrate how they have led to an improvement in our ability to effect meaningful, effective control strategies by improving our knowledge of the atmospheric chemistry of trace gases and particles. Conversely, some examples will also be given of how measurement deficiencies led to misleading conclusions concerning the nature and extent of environmental pollution, and permitted the development of ineffective control strategies. Measurement artifacts for prominent particulate constituents—sulfate, nitrate and organic species—are discussed, focusing on key measurement principles that were developed to overcome those artifacts. The use of tracers and source apportionment techniques to quantify the contributions of sources of pollutants and their precursors is another example of measurement science enabling effective control strategies. The intent of this paper is to illustrate how better measurement science leads to more accurate assessment of pollutant formation and transport processes, and hence to the development of more effective pollutant control strategies.

AB  - Intact migratory routes are critical for the stability of forest-dwelling, neotropical, migratory bird populations, and mortality along migratory pathways may be significant. Yet we know almost nothing about the geography of available stopovers or the possible migratory pathways that connect optimal stopovers. We undertake a spatial analysis of stopover habitat availability and then model potential migratory pathways between optimal stopovers in the eastern United States. Using models of fixed orientation and fixed nightly flight distance between stopovers during spring migration, we explore whether a simple endogenous migratory program is sufficient to ensure successful migration across the modern landscape. Our model runs suggest that the modern distribution of optimum stopovers in the eastern United States can be adequately exploited by birds following migratory pathways defined by fixed-orientation and fixed-distance nightly flights. Longer flight distances may increase the chances of success by enabling migrants to bypass locales offering little habitat. Our results also suggest that most southwest-northeast migratory pathways through the Appalachian mountains are intact. Lack of optimal habitat at key locations in the Southeast causes many modeled pathways to fail. We present a speculative view of regional migration patterns implied by predominant ideas found in stopover ecology literature, and demonstrate the need for broad-scale migration research, in the hope that our approach will foster other continental- and regional-scale projects.

AB  - The plume of Tennessee Valley Authority''s coal-fired Cumberland power plant was sampled during four different days in the summer of 1998 and 1999 from an instrumented helicopter. The extent of formation of ozone and various secondary NOy species in the plume was measured and the rates of loss processes estimated. The rates of these processes were found to be similar during three of the four sampling days. On the fourth day conversion and removal processes within the plume were significantly slower apparently due to lower ambient temperatures, and poor dispersion conditions. On the three more ‘reactive’ days ozone yield (<f>Y</f>) was found to be in the range of 1.5–2.6 molecules of O3 produced per molecule of NOx emitted. The ozone production efficiency, estimated from <f>Y</f> and the average chemical age of the farthest distance sampled, varied from 2.3 to 5.4. [Copyright &y& Elsevier]

AB  - In early 2002, the Tennessee Valley Authority (TVA) completed a revision of its Environmental Management System (EMS). The new EMS is designed to fully align with the International Organization for Standardization (ISO) 14001 EMS standards. The EMS incorporated a new Environmental Review Process as an integral component. It established clear roles and responsibilities for the agency NEPA (National Environmental Policy Act) staff and organizations across TVA, introduced process improvements and standardization measures, and made structural changes to bring about increased efficiency and effectiveness in NEPA reviews. The NEPA process was further strengthened by its integration into the revised comprehensive EMS. A new Environmental Policy and Principles was adopted that reestablished the TVA commitments to environmental protection and stewardship, to assess and minimize the effects of TVA operations on the environment, and to involve the public. An Achievement Plan was developed to assure that TVA meets its corporate environmental commitment; that plan recognized the EMS as the principal tool for achieving that goal. Corporate environmental objectives and targets were established, and new methods to measure the overall environmental performance of TVA were introduced. Significantly, the NEPA process was directly linked to other EMS processes, including those for environmental training, communication and stakeholder involvement, records management, environmental auditing, corrective and preventive action, performance monitoring and reporting, and management review. These systematic linkages work together to reinforce all aspects of NEPA performance and to provide improved environmental compliance, cost savings in environmental management programs, and measurable improvements in achievement of TVA environmental objectives. The TVA experience, which takes an agency-wide rather than a facility-based approach to EMS development, may offer insights and an alternative strategy to other agencies addressing NEPA/EMS implementation issues.

AB  - Gaseous elemental and total (elemental + oxidized) mercury (Hg) in the flue gas from a coal-fired boiler was measured by a modified ultraviolet (UV) spectrometer. Challenges to Hg measurement were the spectral interferences from other flue gas components and that UV measures only elemental Hg. To eliminate interference from flue gas components, a cartridge filled with gold-coated sand removed elemental Hg from a flue gas sample. The Hg-free flue gas was the reference gas, eliminating the spectral interferences. To measure total Hg by UV, oxidized Hg underwent a gas-phase, thermal-reduction in a quartz cell heated to 750 °C. Simultaneously, hydrogen was added to flash react with the oxygen present forming water vapor and preventing Hg re-oxidation as it exits the cell. Hg concentration results are in parts per billion by volume Hg at the flue gas oxygen concentration. The modified Hg analyzer and the Ontario Hydro method concurrently measured Hg at a field test site. Measurements were made at a 700-MW steam turbine plant with scrubber units and selective catalytic reduction. The flue gas sampled downstream of the selective catalytic reduction contained 2100 ppm SO[sub2] and 75 ppm NO[subx]. Total Hg measured by the Hg analyzer was within 20% of the Ontario Hydro results.

AB  - Organic and elemental carbonaceous material constitute significant portions of PM 10 and PM 2.5 mass on a global basis and are typically 35% and 10%, respectively, in urban areas of the southeastern United States. The organic portion of this is a complex mixture of primary compounds and secondary materials formed in situ from primary emissions. These materials derive from a variety of sources that are dynamically changing in time and space, making difficult the quantitative characterization of their sources. Results of measurements of the 14 C content of organic aerosol particles (PM 10 and TSP) sampled at Look Rock, TN are reported in this work with the aim of better estimating bounds to fossil and biogenic sources that contribute to PM mass concentrations. The fraction of fossil-derived carbon in these particles has been estimated as 1 minus the fraction of "modern" carbon, the latter by definition biologically synthesized in equilibrium with atmospheric, cosmic ray-derived 14 CO 2 . Fossil carbon fractions vary in a wide range from less than 10 to about 60% during spring, summer, and fall seasons at this ridge-top site near the Great Smoky Mountains National Park. The implications of these findings on control strategies for the organic carbon fraction of PM 2.5 mass are discussed. [ABSTRACT FROM AUTHOR]

AB  - An air quality model, URM-1ATM, was used to investigate tendencies in fine particle (PM[sub2.5]) species in response to changes in SO[sub2] and NO[subx] emissions in the eastern United States. The model employed the decoupled direct method (DOM) to estimate sensitivities without the need for multiple model runs for different emissions species and geographic regions. The baseline for sensitivities was emissions projected to 2010. Principal geographic regions investigated were east of the Mississippi River, although the contribution of a region to the immediate west of the river was also included in the study. Sensitivities to emissions changes from point sources (SO[sub2] and NO[subx]) and low-level sources (NO[subx]) were computed. PM[sub2.5] species examined were sulfate, organic carbon, and nitrate as well as total fine mass. Results for the midwest, mid-Atlantic, and southeast regions indicated that those regions affect their own aerosol levels the most Aerosols in the northeast were most strongly linked to emissions from the midwest and mid-Atlantic regions. In general, midwest emissions had the most influence of any region on other regions. In addition, the southeast was relatively isolated, having the least influence outside itself and being least affected by neighboring regions. Sulfate was the species most sensitive to emission changes. Finally, the largest potential relative sensitivities of sulfate and organic aerosols, along with PM[sub2.5] mass, to emissions changes were usually modeled to occur outside those areas computed to experience the highest aerosol levels.

AB  - The red spruce (Picea rubens Sarg.) – Fraser fir (Abies fraseri (Pursh) Poir.) forest of the southern Appalachians contains a significant amount of coarse woody debris (CWD) that may affect the nitrogen (N) export signal in streams originating from this N-saturated system. Interpretation of the N sink versus source status of CWD of red spruce and Fraser fir was dependent on the method used. Over a chronosequence of decay, (1) N concentrations suggested a N sink (i.e., a net gain of N of 923% in red spruce and 563% in Fraser fir relative to N in live trees); (2) N contents that reflected changes in density suggested a smaller N sink (i.e., a net gain of N of 218% in red spruce and 125% in Fraser fir relative to N in live trees), but the stoichiometry of N and C suggested a N source in early stages of decay and a N source in the most advanced stage of decay only; and (3) N contents that reflected changes in volume suggested a N source (i.e., a net N loss of –172% in red spruce and –122% in Fraser fir). The C/N ratios in CWD suggested that the shift from a N source to a N sink represented a shift from the mobilization of dissolved organic N to the immobilization of ammonium N and (or) nitrate N. The magnitude of the net change in N contents in both red spruce and Fraser fir was amongst the highest reported in literature, suggesting that CWD plays a particularly important role in N dynamics in N saturated forests.

AB  - La forêt d'épinette rouge (Picea rubens Sarg.) et de sapin de Fraser (Abies fraseri (Pursh) Poir.) des Appalaches méridionales contient une importante quantité de débris ligneux grossiers (DLG) qui pourraient influencer la quantité d'azote (N) exporté dans les cours d'eau en provenance de ce système saturé en N. Dépendamment de la méthode utilisée, les DLG de l'épinette rouge et du sapin de Fraser peuvent être considérés comme une source ou un puits de N. Au cours d'une chronoséquence de décomposition, (1) la concentration de N laisse croire à un puits (c.-à-d. un gain net en N de 923 % pour l'épinette rouge et de 563 % pour le sapin de Fraser relativement à la concentration de N dans les arbres vivants); (2) le contenu en N qui reflète les changements dans la densité laisse croire à un puits moins important (c.-à-d. un gain net en N de 218 % pour l'épinette rouge et de 125 % pour le sapin de Fraser relativement à la concentration de N dans les arbres vivants) mais la stœchiométrie de N et C laisse croire à une source de N seulement au stade initial et au stade le plus avancé de décomposition et (3) le contenu en N qui reflète un changement en volume laisse croire à une source de N (c.-à-d. une perte nette de 172 % pour l'épinette rouge et de 122 % pour le  sapin de Fraser). Le rapport C/N dans les DLG indique que le changement d'une source à un puits de N traduit le passage d'une mobilisation de N organique dissout à une immobilisation sous forme d'ammonium ou de nitrate. L'ampleur de la variation nette du contenu en N tant chez l'épinette rouge que chez le sapin de Fraser est parmi les plus importantes rapportées dans la littérature indiquant que les DLG jouent un rôle particulièrement important dans la dynamique de N dans les forêts saturées en N.[Traduit par la Rédaction] (French) [ABSTRACT FROM AUTHOR]

AB  - An ozone (O[sub3]) exposure study was conducted in Nashville, TN, using passive O[sub3] samplers to measure six weekly out-door, indoor, and personal O[sub3] exposure estimates for a group of 10- to 12-yr-old elementary school children. Thirty-six children from two Nashville area communities (Inglewood and Hendersonville) participated in the O[sub3] sampling program, and 99 children provided additional time-activity information by telephone interview. By design, this study coincided with the 1994 Nashville/Middle Tennessee Ozone Study conducted by the Southern Oxidants Study, which provided enhanced continuous ambient O[sub3] monitoring across the Nashville area. Passive sampling estimated weekly average outdoor O[sub3] concentrations from 0.011 to 0.030 ppm in the urban Inglewood community and from 0.015 to 0.042 ppm in suburban Hendersonville. The maximum 1- and 8-hr ambient concentrations encountered at the Hendersonville continuous monitor exceeded the levels of the 1- and 8-hr metrics for the O[sub3] National Ambient Air Quality Standard. Weekly average personal O[sub3] exposures ranged from 0.0013 to 0.0064 ppm (7-31% of outdoor levels). Personal O[sub3] exposures reflected the proportional amount of time spent in indoor and outdoor environments. Air-conditioned homes displayed very low indoor O[sub3] concentrations, and homes using open windows and fans for ventilation displayed much higher concentrations. [ABSTRACT FROM AUTHOR]

AB  - Salient features of the International Reactor Innovative and Secure (IRIS) are presented here. IRIS, an integral, modular, medium size (335 MWe) PWR, has been under development since the turn of the century by an international consortium led by Westinghouse and including over 20 organizations from nine countries. Described here are the features of the integral design which includes steam generators, pumps and pressurizer inside the vessel, together with the core, control rods, and neutron reflector/shield. A brief summary is provided of the IRIS approach to extended maintenance over a 48-month schedule. The unique IRIS safety-by-design approach is discussed, which, by eliminating accidents, at the design stage, or decreasing their consequences/probabilities when outright elimination is not possible, provides a very powerful first level of defense in depth. The safety-by-design allows a significant reduction and simplification of the passive safety systems, which are presented here, together with an assessment of the IRIS response to transients and postulated accidents.

AB  - The migration of Neotropical birds may provide a robust measure of changing environmental condition along the migratory route. I review previous work on assessing broad-scale stopover quality in the eastern United States and discuss how future research can aid regional environmental assessment. Scientists can quantify how environmental changes affect the migratory system, and then monitor for those effects on migrant abundance from year to year. The cyclical nature of migration provides a constant re-evaluation of habitat quality and spatial distribution by migrant birds. Avian monitoring programs can detect changes in migrant abundance. Migrating birds may thus provide a living sensor of environmental change, enabling broad-scale environmental assessments to detect and address habitat degradation early on, allowing local managers to prioritize restoration efforts accordingly. Understanding the environmental factors driving stopover selection, and how birds move between stopovers during migration, is an important first step. [ABSTRACT FROM AUTHOR]

AB  - Aerosol composition data, simultaneously collected from collocated samplers at an urban, a rural and a background site in the Tennessee Valley, have been compared for all seasons in 2001. Consistent with previous data, organic aerosols and sulfates are the two largest contributors to fine mass throughout the year at all three sites. Levels of major constituents were not significantly different at the rural and background sites during any season, but levels of organic and elemental carbon were higher at the urban site during fall and winter periods. Seasonal trends at all sites showed maxima in summer for sulfate and significant nitrate levels only in winter, but no significant seasonal trend was observed for organic aerosol mass at any site. Year-to-year variability in aerosol composition at the background site is small compared to day-to-day variability within seasons. The appropriate factor for converting organic carbon to organic mass (conventionally *1.4), used in calculating aerosol chemical composition, may vary with season—larger in warm seasons, smaller in cool seasons.

AB  - We compared freshwater mussel assemblages (Bivalvia: Unionidae) in a developing oxbow (old channel) and a newly-cut (new) channel of the Neosho River, Kansas, during 2001. We sampled mussels at approximately 1.5 km intervals, totaling 19 sites in the old channel and seven in the new, by groping substrate from bank to bank in a zigzag fashion along a 100 m reach. We found 1239 live individuals of 20 mussel species in the old channel and 20 live individuals of six species in the new channel. Mussel abundance, diversity and current species richness were greater in the old channel than in the new. Abundance, diversity and historic and current species richness all declined significantly from upstream to downstream in the old channel. Historic richness was greater than current richness in the old channel, but both decreased from upstream to downstream at the same rate. The loss of historic species from the old channel was no different from that in the rest of the Neosho River in Kansas; however, a further decrease in lotic species will likely occur as the channel continues to evolve into an oxbow lake. Canonical correspondence analysis illustrated a substrate compaction, substrate composition and depth gradient in the old channel, with three species in flowing waters with sand and gravel substrate and all other species in still waters with sill substrate. Information regarding habitat use by freshwater mussels is important in designing surveys and recovery plans for rare species (Strayer, 1993). [ABSTRACT FROM AUTHOR]

AB  - Little information is available on how hot water is used in schools. This paper reports field test data on hot water and water heating energy use of a high school cafeteria kitchen. Objectives were to obtain hot water and energy use information and to investigate potential energy efficiency improvements both analytically and experimentally. To achieve these objectives, a suitable test site was located and the cafeteria kitchen gas-fired hot water recirculation loop was instrumented and monitored. Performance of the system was monitored for several months in the as-found condition, with the hot water recirculation-loop pump running continuously. Subsequently, timer control of the recirculation-loop pump was implemented in order to reduce energy consumption, and monitoring was continued for the remainder of the 12-month test period. The configurations were then analyzed as if each had been operating for the entire 12 months, using the actual temperatures and amounts of hot water consumed as observed each day. Several additional improved configurations were also investigated analytically. Energy consumption, overall delivered efficiency, and energy savings were computed on a 12-month basis for the various configurations and the results presented here. Some of the results presented are believed representative of most high school kitchen operations, most notably the fact that schools are in use only about 50 % of the days of each year and normally for less than half of each day when they are in use. This has important generalized implications for appropriate school water heating system design and operation, as discussed in the paper. [ABSTRACT FROM AUTHOR]

AB  - This paper presents field-monitored performance data from a school where a heat pump water heater (HPWH) was installed with a storage tank to preheat water for a gas-fired hot water system with multiple recirculation loops. The results demonstrated the effectiveness of HPWH preheating for high water use areas in the school and confirmed the high thermal losses from the recirculation loop system. The authors discuss the implications of this work as it relates to the overall design strategy for service water heating systems in schools. [ABSTRACT FROM AUTHOR]

AB  - Concern exists as to the status of red spruce (Picea rubens Sarg.) in the Great Smoky Mountains, with evidence both for and against an unprecedented decline in radial growth during the past century. On the basis of a dendrological record from 1850 to 1998, our analyses support a decline in radial growth starting as early as the 1940s through to the 1970s; in the 1970s there was a reversal of this decline. In comparing trees near ridges (2000 m) with those in draws (1500 m), we found differences in the (a) timing of the decline, (b) rate of decline, and (c) homogeneity of the decline, with trees near ridges showing earlier, faster, and more homogeneous declines than trees in draws. We hypothesized that changes in climatic conditions and/or atmospheric pollutants, both of which changed beyond ranges of natural variability, were related to the observed decline in radial growth. In trees near ridges, up to 67.1% of changes in radial growth could be explained by a combination of climatic conditions (7.6%) and annual emissions of nitric oxides (NOx) and sulfur dioxide (SO2) (an additional 59.5%). In trees from draws, up to 38.3% of the changes in radial growth could be explained by climatic conditions only. A conceptual model is presented, where trees in naturally acidic soils with low base saturation provide a sensitive signal for the changing nature of acidic pollutants, but trees in anthropogenically acidifying soils with an initially higher baser saturation provide a signal that is confounded by a transient increase of calcium (Ca) and magnesium (Mg) in the soil that results in a transient increase in radial growth.

AB  - This project's goal was to restore populations of four rare fishes into Abrams Creek. Blount County, TN. These species, all on the US Endangered and Threatened Wildlife List, include two catfishes. the smoky madtom (Noturus bailey) and the yellowfin madlom (N.flavipinnis). the duskytail darter (Etheostoma percnurum) and the spotfin chub (Erimonax monachus). Captive propagation, reintroduction, and non-invasive monitoring techniques were used for this restoration effort, which began in 1986. By 2000, there was evidence of reproduction for all four species. As of 2003, the number of these species stocked in Abrams Creek was 3167 smoky madtoms, 1574 yellowfin madtoms, 3430 duskytail darters, and 11,367 spotfin chubs. Increasing population sizes were indicated for three of the four fishes, and smoky madtom and duskytail darter abundances were nearly comparable to native populations in Citico Creek, Monroe County, TN.

AB  - The article focuses on the education gap between customers and electric utility representatives when it comes to power quality. Despite progress made in the identification and correction of power quality problems, the concept of power quality itself remains a mystery to many engineers and most decision makers within industrial facilities. Also, decision makers are not particularly interested in technical details, but rather in the business effects of interruptions caused by power quality disturbances and in any proposed solution to a known problem for the respective facility.

AB  - Concerns about global warming and discussions of possible mitigation measures have generated a need for information on changes in soil C over time. The objective of this study was to determine if there was a change in soil C concentration in an aggrading oak forest over a 26-yr interval. Using permanently identified points on the Camp Branch Experimental Watershed, soil samples were first collected in July of 1976 and archived. During July of 2002, 11 points covering 6 of the 18 soil series present on the watershed were resampled. The series chosen represent a range in topographic positions and forest cover types. In both 1976 and 2002, a bucket auger was used to collect samples at depth intervals of 0 to 10, 10 to 30, and 30 to 50 cm. Both sample sets were analyzed in 2002 using a loss on combustion technique to determine organic C concentration. A bootstrapping data analysis indicated an increase (95% confidence interval) in the concentration of C in the 0- to 10-cm depth. No change in C concentration occurred in the 10- to 30- or 30- to 50-cm samples. Average soil C concentration in the 0- to 10-cm samples increased from a mean of 20.8 g kg -1 in 1976 to 35.9 g kg -1 in 2002. Among soil series, concentrations ranged from 9.5 to 28.9 g kg-1 in 1976 and 22.1 to 64.7 g kg-1 in 2002. Although the sample numbers are limited, results indicate that average soil C concentration in the top 10 cm of the mineral soil increased by 73% at this site over a 26-yr interval.

AB  - High Temperature Superconductor (HTS) SuperVAR dynamic synchronous condensers (DSC) developed by American Superconductor have a small foot print, are readily transportable, and are expected to be an economic option for providing peak and dynamic reactive compensation to a power system. HTS DSC machines are also inherently stable to close in faults and can provide up to twice their nominal rating for about one minute (peak rating) during depressed voltage events. Last, but not least, HTS DSC machines use less than half of the energy of a conventional synchronous condenser and about the same amount of energy as a modern flexible AC Transmission System (FACTS) device consumes. It is expected to be highly reliable. The first FITS DSC machine is being operated at an arc furnace where it is being tested for its ability to mitigate flicker and provide dynamic power factor compensation. This location also exposes the machine to a large number of transients providing an excellent accelerated age test of the device. This paper describes features and test results of the HTS DSC.

AB  - Abstract: Current fine particle NAAQS specify 24h integrated mass measurements as the compliance metric. However, the value of continuous short-time resolution sampling (1h or less) is recognized and being included in US EPA-monitoring strategies. An extensive body of fine mass concentration data has been acquired using continuous PM2.5 monitoring by TEOM at Look Rock, TN, augmented by trace gas measurements and, during enhanced monitoring periods, continuous sampling for aerosol sulfate (2 methods) and elemental (black) carbon. Continuous data are compared to the 24h-averaged values of mass and composition from integrated samplers at the site, and for fine mass and sulfate are found to be excellent (). We then report the diurnal variations in concentrations from extensive continuous monitoring during 3 summer periods (2000–2002) and for more limited periods throughout calendar year 2001. Levels of the several continuously measured gases and particulate constituents vary in magnitude diurnally according to expected patterns based on their emissions, their formation and loss processes, their lifetimes toward wet and dry deposition, the dynamics of up-slope—down-slope circulation, and solar-driven boundary layer growth and decay. Thus, concentrations of short-lifetime gases have minima at sunrise and maxima in the evening. Long-lived primary species (CO and black carbon) increase in mid-morning as the boundary layer height reaches the site and decay thereafter. Long-lived secondary species (sulfate and fine mass) show little diurnal variability. Factors controlling the observed diurnal variability thus significantly influence the extent and timing of human exposure to pollutant species, as well as affecting visibility impairment in complex terrain environments near the Great Smoky Mountains National Park.

AB  - Abstract: Continuous measurements were made of gaseous NH3, gaseous HNO3, PM2.5 sulfate, aerosol mass, air temperature, and relative humidity (RH), and 24-h filter samples of PM2.5 aerosols were analyzed to determine the effects of ambient NH3 levels on PM2.5 aerosol composition. These measurements were conducted from 2 to 15 August 2002, at Look Rock, TN, at an air monitoring station located on a mountain ridge (elevation ∼800m MSL) on the southwestern edge of the Great Smoky Mountains National Park. A strong diurnal pattern was observed for gaseous NH3 levels at this site with higher daytime and much lower NH3 during the night hours. The diurnal variability of both gaseous NH3 concentrations and RH suggests that conditions controlling aerosol nitrate formation and acidic aerosol neutralization are complex. The observations during this 2-week long sampling period showed that measurable NH4NO3 aerosol was not present under the ambient conditions encountered. However, modest perturbations from observed ambient conditions could have enabled NH4NO3 aerosol production. The extent of neutralization of sulfate aerosol collected on filters indicates that there was insufficient regional NH3 to neutralize the acidic sulfate aerosols to the degree predicted from local NH3 and RH conditions. Incomplete neutralization of acidic sulfate could also result if neutralization proceeds more slowly under field conditions compared to laboratory conditions or model predictions. Continuous measurements of aerosol ammonium and/or acidity are needed to determine if ammonia availability or kinetic limitations (or both) restrict neutralization of acidic sulfate aerosols, a key factor for modeling and exposure studies.

AB  - Data on atmospheric levels of sulfur dioxide (SO2) and sulfate were examined to quantify changes since 1989. Changes in sulfur species were adjusted to account for meteorological variability. Adjustments were made using meteorological variables expressed in terms of their principal components that were used as predictors in statistical models. Several models were tested. A generalized additive model (GAM)—based in part on nonparametric, locally smoothed predictor functions—computed the greatest association between sulfate and the meteorological predictors. Sulfate trends estimated after a GAM-based adjustment for weather-related influences were found to be primarily downward across the eastern United States by as much as 6.7% per year (average of -2.6% per year), but large spatial variability was noted. The most conspicuous characteristic in the trends was over portions of the Appalachian Mountains where very small (average = -1.6% per year) and often insignificant sulfate changes were found. The Appalachian region also experienced a tendency, after removing meteorological influences, for increases in the ratio RS of sulfate sulfur to total sulfur. Before 1991, this ratio averaged 0.33 across all sites. Appalachian increases in RS were equivalent to 0.07 during 1989–2001 (significant for most sites at the 0.05 level), or nearly 2 times the average change at the other sites. This suggests that conditions over the Appalachians became notably more efficient at oxidizing SO2 into sulfate. Alternatively, subtle changes in local deposition patterns occurred, preferentially in and near mountainous monitoring sites, that changed the SO2–sulfate balance. [ABSTRACT FROM AUTHOR]

AB  - Abstract: Ten air-quality samplings flights were performed over the San Diego metropolitan area during July 2003. One of the objectives of these flights was to assess the contribution of the offshore pollution sources (civilian and military vessels) to the air quality in the region. The flights, which took place during the mid-day hours in the lower levels of the boundary layer, originated offshore and proceeded eastwards through a series of concentric arcs covering an area of approximately 600km2. The data from the continuous gas analyzers were translated to image plots that enabled the determination of the impact of the various sources on air quality. The results revealed that the offshore sources could often be detected (at least during five of the 10 flights) from their SO2 plume. However, the area covered by these plumes and the concentrations were significantly lower than those measured over other parts of the domain due to sources south of the region. It was further observed that vehicular traffic contributed in a major source way to the formation of ozone. During most flights the pollution cloud, originating over the high traffic area in the vicinity of the downtown area, could be tracked ‘downwind’ until the completion of the photochemical processing. By then, most of the NO X had been converted to NO Z , and peak O3 levels caused by the local emissions had started to ebb. Also, during most flights boundary layer peak levels of O3 exceeded 100ppbv, and in one case were above 140ppbv. [Copyright &y& Elsevier]

AB  - Abstract: The Community Multiscale Air Quality (CMAQ) modeling system developed by the United States Environmental Protection Agency (USEPA) was used along with the PSU/NCAR mesoscale modeling system MM5 to study air quality modeling sensitivity to various planetary boundary layer (PBL) schemes implemented in MM5. Two 37-day periods, representing typical summer and winter periods, were selected for the simulations. The MM5 domain covered the continental US while the CMAQ domain covered much of the central and eastern US. There were 34 vertical layers in MM5 and 18 in CMAQ. The horizontal resolution was 36km for both. MM5 was run with five of the seven commonly used PBL schemes to generate a series of gridded meteorological fields. The data were then processed and converted by the meteorology–chemistry interface processor (MCIP) to produce meteorological input for CMAQ, in conjunction with the emissions data prepared by the Sparse Matrix Operator Kernel Emissions (SMOKE) System. The sensitivity of MM5–CMAQ modeling to the various PBL schemes was assessed and quantified by comparing model output against observations from the meteorological and the air quality monitoring networks within the CMAQ domain. The meteorological variables evaluated included surface (2-m) and 850-mb temperature, 10-meter and 850mb wind speed and direction, 2-m mixing ratio, surface pressure, and cloud fraction over 50 surface sites and 21 upper air sounding sites. The CMAQ variables included gaseous species O3, NO2, NO x , SO2 and fine particulate matter PM2.5 for over 2000 monitoring stations. A new 3-2-1 objective evaluation approach was developed to enhance the model sensitivity analysis. Results of evaluation of these variables indicate that domain-wide the performance of neither model was sensitive to the PBL schemes. Although large differences of PBL height existed across the meteorological simulations, they did not appreciably affect the CMAQ performance. On an urban scale, differences across the CMAQ simulations were large enough for the model to be considered sensitive, although no favorable PBL scheme was identified. It is suggested that domain-wide the lack of sensitivity of the MM5–CMAQ modeling system to the PBL schemes was mainly attributed to the parameterization of vertical eddy diffusivity in CMAQ and the four-dimensional data assimilation (FDDA) in MM5.

AB  - This paper presents the design and experimental demonstration of a superior high-power-device self-powered emitter turn-off thyristor (SPETO). Different from conventional high-power devices which require external power input for their gate drivers, the SPETO achieves optically controlled turn on and turn off, and all of the internal power required is self-obtained. A low-loss gate-drive circuit is implemented which allows the simple power-up operation. During a normal switching operation, the SPETO obtains a power for the gate drive during its turn-on operation. A novel switching strategy is also introduced to minimize the gate-drive power requirement. The SPETO greatly reduces costs and increases the reliability of power converters since no external power supply for device gate drive is required. Therefore, the SPETO is suitable for high-power high-frequency voltage-source-converter applications. [ABSTRACT FROM AUTHOR]

AB  - Abstract: An air quality modeling system—“Models-3/CMAQ”—is studied to determine the relationship between simulated cloud cover and atmospheric sulfur. Sulfur dioxide oxidation to sulfate occurs in the atmosphere through gas-phase reactions and reactions in clouds. The latter heterogeneous reactions can be rapid compared to gas-phase chemistry and a model must correctly simulate cloud cover to avoid serious bias. An evaluation of CMAQ revealed serious problems with diagnosed cloud cover and a bias in simulated sulfate production that was consistent with cloud biases. CMAQ modifications were tested to determine the sensitivity of the sulfur balance to cloud modeling assumptions. The model''s vertical layer structure, limits on subgrid-scale cloud base and top heights, and the ability to simulate subgrid-scale convective cloud formation were found to be important. After applying model changes, atmospheric sulfur simulations were less biased and sulfur dioxide and sulfate were in better balance. [Copyright &y& Elsevier]

AB  - Flexible AC transmission systems (FACTS) devices can control power flow in the transmission system to improve asset utilization, relieve congestion, and limit loop flows. High costs and reliability concerns have restricted their use in these applications. The concept of distributed FACTS (D-FACTS) is introduced as a way to remove these barriers. A new device, the distributed static series compensator (DSSC), attaches directly to existing HV or EHV conductors and so does not require HV insulation. It can be manufactured at low cost from conventional industrial-grade components. The DSSC modules are distributed, a few per conductor mile, to achieve the desired power flow control functionality by effectively changing the line reactance. Experimental results from a prototype module are presented, along with examples of the benefits deriving from a system of DSSC devices. [ABSTRACT FROM AUTHOR]

AB  - Critical load values are calculated to determine ecosystem responses to deposition in a given area; these values may act as a tool to identify sensitive ecosystems in further need of protection. This overview provides an introduction to nitrogen critical loads for policy makers and parties involved in managing nitrogen deposition including electric utility generators, transportation managers and automobile manufacturers, and large-scale agricultural operators in the United States. It examines the use of the critical loads concept in European nations for establishing policy guidelines, current research on nitrogen critical loads in the U.S., and the development of nitrogen critical loads modeling and mapping.

AB  - As an industry customer of electric power, an electrical arc furnace (EAF) is a major flicker source that causes major power quality problems. For a 40-MVA EAF in Tennessee, USA, a cascade-multilevel converter (CMC)-based STATic synchronous COMpensator (STATCOM) with high bandwidth is proposed for EAF flicker mitigation. In this paper, flicker mitigation techniques by using a CMC-based STATCOM are presented and verified through a transient network analyzer (TNA) system. The required STATCOM capacity is first studied through a generalized steady-state analysis. Second, the STATCOM control strategy for flicker mitigation is introduced, and simulation results are given. Finally, a TNA system of the STATCOM and an EAF system are designed and implemented. Experimental results from the TNA test show that the proposed CMC-based STATCOM and its controller can efficiently and rapidly mitigate the EAF flicker. [ABSTRACT FROM AUTHOR]

AB  - Emphasis on maintenance, repair, and operations inventory (or MRO inventory) can lead to improved inventory control, reduced operational costs, enhanced productivity, and increased cost accounting accuracy. To review the benefits of MRO inventory reduction, as well as highlight the management challenges associated with the process, a case study of the Tennessee Valley Authority (TVA) is presented. TVA is a not-for-profit electric power generation entity. TVA standardised inventory policies and procedures. Their comprehensive five-year plan included employee training, changes in organisational structure and strategy, reduced MRO inventories and the establishment of new growth drivers. Net inventory reductions of $47 million were realised. Suggestions for future MRO inventory reductions as well as replication of the management involvement and improvement process in other organisations are included. [ABSTRACT FROM AUTHOR]

AB  - Several different types of constructed wetland systems are being used as decentralized treatment systems including surface-flow, subsurface-flow, vertical-flow, and hybrid systems. Archetypical wetland systems have design strengths and weaknesses, and therefore it should be possible to design combined (integrated) systems to optimize a number of important treatment processes. This study provides comparative efficacy data for two integrated wetland treatment systems (IWTS) designed to enhance treatment of medium strength wastewater generated from a pilot-scale intensive fish farm. Results from the twenty eight months study included consistently high removal of COD (84% +) and ammonia nitrogen (93%) in both systems. Initially, phosphorus removal was also high (>90%) in both systems, but removal efficacy declined significantly over time. Nitrate removal was significantly better in the system that provided sequential aerobic and anoxic environments. Short hydraulic retention times coupled with sustained removal of COD and ammonia indicate that the ReCip components could be a least-cost wastewater treatment technology in the decentralized market sector.

AB  - Successful reproduction and development of strong year classes of fish in storage reservoirs are commonly associated with reproductive seasons of high water level and extensive flooding. Responses to flooding are likely to be less pronounced or altogether different in mainstem navigation reservoirs that experience limited water level fluctuation. In these reservoirs, water regime characteristics such as timing of flooding, instability of water level, and water retention could supersede the effects of water level. We examined existing data to identify aspects of the water regime that have detectable consequence on juveniles of selected taxa in a sequence of four reservoirs of the Tennessee River that exhibited relatively small annual rises. Empirical models relating density of selected age-0 centrarchids to water regime suggested that descriptors of spring and summer flow through the reservoirs, water level instability, and summer water level were better related to juvenile densities than was spring water level. Different water regimes had different effects on the study species, and presumably other species in the fish communities. Therefore, a diversity of water regimes rather than a rigid rule curve is likely most beneficial to the long-term permanence of the fish assemblages of the study reservoirs. Fixed rule curves produce drawdown zones devoid of vegetation consisting primarily of mudflats of limited ecological value to floodplain species, and maintenance of water levels within the rule curve force operational drops and rises that adversely affect littoral spawners. In developing water management plans, regulatory agencies should consider incorporating managed randomness into rule curves. [ABSTRACT FROM AUTHOR]

AB  - TVA, EPRI, Global Energy Partners, LLC, ClearWater Tech, LLC and Superior Catfish Products (Macon, Mississippi) partnered to conduct research and demonstrate beneficial effects of applying gaseous and aqueous ozone in catfish processing. Utilizing an HDO3-III skid mounted ozone unit manufactured by ClearWater Tech, LLC, various processing areas in the Superior Fish Products catfish processing plant were evaluated in August 2005 to determine if aqueous ozone could reduce the microbial load in the processing line and on finished product. In the offal room, gaseous ozone was introduced to determine if odors could be reduced while catfish by-products were being loaded into trucks also located in the offal room. The utilization of aqueous ozone as a final rinse for processing equipment was also tested. All tests were replicated five times and a completely randomized design was used to statistically analyze resulting data. Standard Laboratories, Inc. of Starkville, MS was contracted to conduct all microbial analyses. It was found that aqueous ozone was very effective in significantly reducing microbial loads on live catfish entering the plant. Finished catfish fillets washed in ozonated water showed significant reductions in total plate counts. Ozonation at the fillet machine could be beneficial. Utilizing aqueous ozone as a final wash after using soap and a chlorine sanitizer was of no benefit and actually removed the residual chlorine and led to increased plate counts. Gaseous ozone reduced odors in the offal room rapidly and effectively. Utilization of ozone for odor reductions will require ozone monitoring equipment that ensures employee safety.

AB  - An 8 MVAR, 13.8 kV Superconducting Dynamic Synchronous Condenser (SDSC) prototype was tested on the Tennessee Valley Authority (TVA) grid for about a year. It shared a bus with an arc furnace. The SDSC was subjected to transient currents and harmonics created by the arc furnace, which consisted of up to 50 % negative sequence and 20% zero sequence components. The SDSC operated successfully in the presence of such high transient/harmonic currents. It provided cycle by cycle correction of voltage during operation. The benefits of voltage correction were observed both at the local bus and at the generator bus of a power generation station several miles away. Currently two commercial units rated 12 MVAR, 13.8 kV, are on order by TVA and are scheduled for delivery in December 2006 and March 2007. These units will be skid-mounted for easy installation on site. This paper discusses test results of the prototype unit operation on the grid and describes its potential applications for voltage support in wind farms. [ABSTRACT FROM AUTHOR]

AB  - Abstract: Previous work with both class F and class C fly ash indicated minimal leaching from most fly ashes tested. However, the addition of NO x  removal equipment might result in higher levels of ammonia in the fly ash. We have recently been testing fly ash with a wide range of pH (3.7–12.4) originating from systems with NO x  removal equipment. Leaching experiments were done using dilute CaCl2 solutions in batch and columns and a batch nitric acid method. All methods indicated that the leaching of heavy metals was different in the highest ammonia sample tested and the high pH sample. However, toxicity testing with the Microtox© system has indicated little potential toxicity in leachates except for the fly ash at the highest pH (12.4). When the leachate from the high pH fly ash was neutralized, toxicity was eliminated. [Copyright &y& Elsevier]

AB  - A global view of power system's frequency behavior opens up a new window for analyzing system's dynamics. With the aid of global positioning system, measurements from different locations would have synchronous time; therefore a system-wide observation and analysis would be possible. As part of the US-wide power frequency monitoring network project this paper focus on simulation study results of power frequency dynamics of the Eastern U.S. system. The study assesses the frequency measurement accuracy needed to observe frequency dynamics from events such as remote generation drops. Electromechanical-wave propagation phenomena during system disturbances have been observed. The speeds of electromechanical-wave propagation in different areas of the U.S. systems were estimated and their characteristics were discussed. [ABSTRACT FROM AUTHOR]

AB  - The article describes a system evaluation tool to guide business enterprises regarding mercury compliance strategy in the U.S. Several states have mandated faster and/or deeper reductions in power plant mercury emissions than those called for by the U.S. Clean Air Mercury Rule (CAMR). Unfortunately, differences between plants make accurate evaluation of control options difficult. The modeling tool developed by the company Niksa Energy Associates called MercuRator solves that problem. Because it is based on dynamic reaction analysis (DRA), its equations account for the rates of all chemical reactions in a gas cleaning system that affect mercury emissions.

AB  - The occurrence of mercury depletion events (MDE) in the Polar Regions during the spring periods has raised global concern due to the biomagnifications of the deposited mercury into the aquatic food chain. However, it now appears that MDE is not limited to the Polar Regions and can also occur at mid-latitudes. Diurnal cycles of mercury, ozone, and BrO behavior based on short-time resolution measurements are presented for the Dead Sea, Israel, for Summer 2006. The results show that mercury depletion events occur almost daily, accompanied always by the presence of BrO and concurrent ozone destruction. The intensity of the MDE corresponded to increasing BrO levels. Mercury depletions of more than 40% were observed when BrO levels rose above 60–70 ppt. Based on the present measurements and supported by theoretical considerations, it appears that BrOs (BrO + Br) is the primary species responsible for the mercury depletion at the Dead Sea. The present study also suggests, especially at low ozone levels, that the Br atom may play a major role in conversion of the gaseous elemental mercury to the reactive species, HgBr2. The implications of the present study are that even at low BrO levels (<10 ppt), mercury depletion may well occur at other mid-latitude sites and thus needs to be taken into consideration in the global mercury cycle.

AB  - Sources of carbonaceous aerosols collected from three sites of Chattanooga, TN (CH), Muscle Shoals, AL (MS), and Look Rock, TN (LR) in the Tennessee Valley Region (TVR) were apportioned using both organic tracer-based chemical mass balance (CMB) modeling and radiocarbon (14C) measurement and the results were compared. Eight sources were resolved by CMB, among which wood combustion (averaging 0.92μgm−3) was the largest contributor to primary organic carbon (OC) concentrations, followed by gasoline exhaust (0.35μgm−3), and diesel exhaust (0.18μgm−3). The identified primary sources accounted for 43%, 71%, and 14% of measured OC at CH, MS, and LR, respectively. Contributions from the eight primary sources resolved by CMB could explain 107±10% of ambient elemental carbon (EC) concentrations, with diesel exhaust (66±32%) and wood combustion (37±33%) as the most important contributors. The fossil fractions in total carbon determined by 14C measurements were in reasonably good agreement with that in primary (OC+EC) carbon apportioned by CMB in the MS winter samples. The comparison between the 14C and CMB results revealed that contemporary sources dominated other OC in the TVR, especially in summertime (84% contemporary). [Copyright &y& Elsevier]

AB  - Wind has become one of the fastest growing sources of renewable energy worldwide, but widespread and often extensive fatalities of bats have increased concern regarding the impacts of wind energy development on bats and other wildlife. We synthesized available information on patterns of bat fatalities from a review of 21 postconstruction fatality studies conducted at 19 facilities in 5 United States regions and one Canadian province. Dominance of migratory, foliage- and tree-roosting lasiurine species (e.g., hoary bat [Lasiurus cinereus]) killed by turbines was consistent among studies. Bat fatalities, although highly variable and periodic, consistently peaked in late summer and fall, coinciding with migration of lasiurines and other species. A notable exception was documented fatalities of pregnant female Brazilian free-tailed bats (Tadarida brasiliensis) in May and June at a facility in Oklahoma, USA, and female silver-haired bats (Lasionycteris noctivagans) during spring in Tennessee, USA, and Alberta, Canada. Most studies reported that fatalities were distributed randomly across turbines at a site, although the highest number of fatalities was often found near the end of turbine strings. Two studies conducted simultaneously in the same region documented similar timing of fatalities between sites, which suggests broader patterns of collisions dictated by weather, prey abundance, or other factors. None of the studies found differences in bat fatalities between turbines equipped with lighting required by the Federal Aviation Administration and turbines that were unlit. All studies that addressed relationships between bat fatalities and weather patterns found that most bats were killed on nights with low wind speed (<6 m/sec) and that fatalities increased immediately before and after passage of storm fronts. Weather patterns may be predictors of bat activity and fatality; thus, mitigation efforts that focus on these high-risk periods could reduce bat fatality substantially. We caution that estimates of bat fatality are conditioned by length of study and search interval and that they are biased in relation to how searcher efficiency, scavenger removal, and habitat differences were or were not accounted for. Our review will assist managers, biologists, and decision-makers with understanding unifying and unique patterns of bat fatality, biases, and limitations of existing efforts, and it will aid in designing future research needed to develop mitigation strategies for minimizing or eliminating bat fatality at wind facilities.

AB  - Three mathematical models of air quality (CMAQ, CMAQ- MADRID, and REMSAD) are applied to simulate the response of atmospheric fine particulate matter (PM2.5) concentrations to reductions in the emissions of gaseous precursors for a 10 day period of the July 1999 Southern Oxidants Study (SOS) in Nashville. The models are shown to predict similar directions of the changes in PM2.5 mass and component (sulfate, nitrate, ammonium, and organic compounds) concentrations in response to changes in emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and volatile organic compounds (VOC), except for the effect of SO2 reduction on nitrate and the effect of VOC reduction on PM2.5 mass. Furthermore, in many cases where the directional changes are consistent, the magnitude of the changes are significantly different among models. Examples are the effects of SO2 and NOx reductions on nitrate and PM2.5 mass and the effects of VOC reduction on organic compounds, sulfate and nitrate. The spatial resolution significantly influences the results in some cases. Operational model performance for a PM2.5 component appears to provide some useful indication on the reliability of the relative response factors (RRFs) for a change in emissions of a direct precursor, as well as for a change in emissions of a compound that affects this component in an indirect manner, such as via oxidant formation. However, these results need to be confirmed for other conditions and caution is still needed when applying air quality models for the design of emission control strategies. It is advisable to use more than one air quality model (or more than one configuration of a single air quality model) to span the full range of plausible scientific representations of atmospheric processes when investigating future air quality scenarios.

AB  - Due to the increase in power demand and limited investment in new infrastructure, existing overhead power transmission lines often need to operate at temperatures higher than those used for the original design criteria. This has led to the accelerated aging and degradation of splice connectors, which have been manifested by the formation of hotspots that have been revealed by infrared imaging during inspection. The implications of connector aging is twofold: 1) significant increase in resistivity of the splice connector (i.e., less efficient transmission of electricity) and 2) significant reduction in the connector clamping strength, which could ultimately result in separation of the power transmission line at the joint. Therefore, the splice connector appears to be the weakest link in the electric power transmission lines. This paper presents a protocol for integrating analytical and experimental approaches to evaluate the integrity of a full tension single-stage splice connector assembly. [ABSTRACT FROM AUTHOR]

AB  - We present and compare demographic data for cerulean warblers (Dendroica cerulea) from 5 study sites across the range of the species from 1992 to 2006. We conducted field studies to collect data on daily nest survival, nest success, and young fledged per successful nest, and we used data to estimate fecundity. Daily nest survival, nest success, young fledged, and fecundity varied widely across the cerulean range and among years. Study sites in agriculture-dominated landscapes (Mississippi Alluvial Valley, IN, and MI, USA) had negative growth rates in all years monitored because measured values of nest success and young produced per successful nest were incapable of offsetting apparent mortality. Ontario (Canada) and Tennessee (USA) populations had greater nest success and fecundity but still appeared to be incapable of producing stable populations (λ = 1) under field-measured and assumed conditions. We had survival data only for one site (Ontario); thus, additional survival data are greatly needed to enable more reliable estimates of population growth. Conservation strategies for cerulean warblers in agriculture-dominated landscapes (e.g., Mississippi Alluvial Valley, IN, and MI) may require major landscape-level habitat reconfiguration to change agriculture-dominated landscapes to forest-dominated landscapes to increase fecundity. Conservation strategies in predominantly forested landscapes in the core of the range (e.g., TN) require a focus on minimizing habitat loss and developing management prescriptions capable of improving fecundity. In both cases, based on sensitivity and elasticity analyses, efforts to improve survival during the nonbreeding season would have the greatest positive effect on population growth.

AB  - Abstract: Planners in a rapidly urbanizing area must take into account trade-offs between multiple environmental issues of concern. A 15-county region, centered on Charlotte, North Carolina, is experiencing a boom in growth resulting in both air and water quality concerns. We examine changes to environmental and socio-economic factors across the region for two contrasting alternative future scenarios of land use development. We found that a “compact centers” development, with relatively high density, resulted in improved environmental quality in most counties as a result of lower land consumption. The compact centers development was associated with greater non-point source phosphorus and sediment loads in watersheds that contained urban centers. In contrast, the greater land consumption associated with the medium density development consumed high nutrient-generating agricultural lands, resulting in lower non-point source nitrogen loading to waterways. We also found that compact center development made sense economically in urban areas and reduced expenditures in rural areas. However, compact centers carried the risk of lower tax revenues in rural areas if future values of multi-unit houses were valued at current market rates. By incorporating spatial dynamics in our assessment we provided a means to evaluate future environmental and economic patterns under different alternative growth scenarios across multiple counties. In addition, we found that by conducting our analysis at two different scales (e.g., regional and local), decisions on where to target development and resources could be refined.

AB  - Twelve research fights were performed during August 2005 over the Dallas (Texas) metropolitan area. The primary objective was to estimate the relative contribution of primary emissions from large point sources, i.e., major power plants, compared with mobile sources in terms of O3 production. The distinction between the source types was derived from concurrent measurements of SO2 (tracer for point sources) and CO (tracer for mobile sources) relative to levels of O3 and NO x (the O3 precursor). The flights also examined the vertical structure of the atmosphere and its effect on the dispersion/dilution of the trace gases. During the first half of the study the O3 levels in the Dallas area were relatively low and only during the second half were significantly elevated O3 levels observed. For the latter period the relationship between maximum O3 levels, the air mass chemical age and the O3 yield are evaluated. The results also revealed that mobile sources are the main contributors to the elevated O3 levels in the Dallas area. [Copyright &y& Elsevier]

AB  - The article presents specifications in repairing low-pressure rotors with cracked blade attachments among power plants in the U.S. Stress corrosion cracking in the blade attachments of their low-pressure rotors mostly happen due to excessive work. Solutions of such problems range from redesign of the attachment and blade replacement to in-situ weld repair. Approaches can significantly restore the steam turbine performance while minimizing outage duration. However, proper installation of the system is the most efficient approach in preventing the problems to happen.

AB  - A late afternoon polluted air parcel transported from the Houston metropolitan area was monitored by an instrumented aircraft throughout the night of 21–22 July, 2005. Sampling was conducted during three flight segments over several downwind areas that were identified by a controllable meteorological balloon released from the Houston area at sundown. Samples were taken for approximately 2h over each area. Using carbon monoxide as a tracer of the urban plume, it was revealed that the dilution inside the plume was relatively small. Ozone levels of up to 120ppb were found in the plume at the furthest downwind distance, some 250km northwest of Houston, with plume transport in the direction of the Dallas metropolitan area. The data further suggest that the nighttime conversion of NO x to NO z was very rapid, with complete (∼100%) conversion by the end of the night. At two locations the urban plume mixed with fresh emissions from power plants. At these sampling points ∼50% of the NO y had already been converted to NO z , thus indicating very rapid oxidation at night. [Copyright &y& Elsevier]

AB  - Abstract-Partial discharges (PDs) generate wideband radio-frequency interference which can be used for noninvasive monitoring of discharges. This paper presents a novel method based on this principle for PD monitoring of substations. The significant advantage of this method lies in the ability to detect PD sources in energized equipment anywhere within a substation compound during normal operating conditions. The results obtained from the prototypes installed in the U.K. and U.S. substations are reported. Results include correlation with apparent charge and daily recordings obtained before, during, and after the failure of a 132-kV current transformer and 69-ky voltage transformer.

AB  - Long term protection and maintenance of ecological communities and populations must consider the effect of atmospheric pollutants in addition to stressors that occur on the ground. We describe a technique for identifying species ranges and ecosystems across the landscape where there could be potential effects from air toxics releases. We modified the ranking equations for hazardous air pollutants (HAPs) from the Chemical Scoring and Ranking Assessment Model (SCRAM) to come up with a weighted relative toxicity value. The model combines toxicity rankings from SCRAM, chemical ambient air concentration data from the Assessment System for Population Exposure Nationwide model, and species richness data from the Southeast Gap Analysis Project. The final output was a 30-m pixel grid of potential vulnerability to HAP exposures. We found that the model, in general, resulted in a circular pattern around major urban areas with vulnerability decreasing with distance from the urban center. Those areas having high acreage of federal, state, and locally protected lands were also highlighted by the models added weight for species richness. Since the final toxicity maps were in a raster format the data can be aggregated into any number of assessment units for use by multiple levels of decision makers including federal and state entities who want to compare relative toxicity exposures across a region and local groups who want to evaluate the vulnerability of lands under their management.

AB  - Erosion pins were installed on 32 banks in five tributaries of the Little River, eastern Tennessee, to quantify the contributions of streambanks to stream sediment loads and better understand the processes of streambank erosion. In the first two years of monitoring, erosional losses from streambanks were readily measurable, with a median loss of 1 cm bank-1. Streambanks lost material through subaerial erosion processes as well as by mass movements and removal of sediment by hydraulic forces. Although the highest median erosion rates occurred below the water line, erosion also occurred on the upper banks. Initial results demonstrate that channel bank instability is widespread and channel banks are potentially important sources of sediment in these tributaries. Two observations made in this study, of streambank erosion independent of hydraulic forces and of bank undercutting active during drought, call attention to gaps in knowledge that affect models of streambank processes and efforts to improve water quality in headwater streams.

AB  - Public policy, technological improvements, monetary incentives, and "green" awareness are combining to promote the deployment of electric "plug-in" vehicles over the next ten years. One of the important benefits envisioned from the transition of the automotive fleet to these new technologies is the reduction in the burning of fossil fuels by using electricity instead of gasoline. However, the production of electricity can itself involve the use of fossil fuels; for example, in the Tennessee Valley, approximately 50 percent of the power generated comes from coal. This paper examines key questions associated with this transition. It estimates the likely range of penetration possibilities for electric transportation in the Tennessee Valley and the associated impact on carbon dioxide emissions from those vehicles. In order to make these calculations, the authors consider not only issues associated with fossil fuel's share in the generation mix but also the assumption regarding how much on-peak charging occurs for the vehicle fleet. It compares emission scenarios to those from a hybrid and a regular vehicle fleet of the same size. Finally, the paper makes a range of estimates of the value of the net savings, based on a range of the opportunity costs associated with carbon emissions. [ABSTRACT FROM AUTHOR]

AB  - increases in atmospheric C have resulted in concerns about global warming and interest in finding the means to sequester atmospheric C through land management strategies. The purposes of this study were to: (i) compare changes in mineral soil C after a 30-yr interval, and (ii) examine the potential roles of soil N, soil texture, and topography in these changes. The Camp Branch watershed is a second-growth oak-dominated mixed hardwood forest on the Cumberland Plateau in central Tennessee. In July 1976, soil samples were collected at permanently identified points and archived. These points were resampled in July 2006 and both the archived and new samples of the 0- to 10-cm increment of the mineral soil were analyzed for C and N. Comparisons revealed that the changes in C and N were distinct to each of the eight soil series occurring on the site. Comparison of 2006 samples to 1976 samples indicated that changes in C concentration ranged flora - 13.1 to 12.0%. Changes in C mass ranged from -11.3 to 8.3%. Increases in C were most closely associated with increases in the C/total N ratio. The change in C was positively correlated with the change in exchangeable inorganic N (r² =0.31, P < 0.0001). An overstory inventory indicated a decline in oak domination and site- specific changes in basal area, density, and stand age. Since regression analysis revealed that the change in C was not predicted by topographic factors or soil texture, we speculate that changes in forest cover influenced the changes in mineral soil C.

AB  - Daily (24 h) and hourly air quality data at several sites are used to examine the performance of the fifth-generation Pennsylvania State University–NCAR Mesoscale Model (MM5)–Community Multiscale Air Quality Model (CMAQ) system over a 3-month period in 2003. A coarse (36 km) model grid was expected to provide relatively poor performance for ozone and comparatively better performance for fine particles, especially the more regional sulfate and carbonaceous aerosols. However, results were different from this expectation. Modeling showed significant skill for ozone at several locations but very little skill for particulate species. Modeling did poorly identifying surface wind directions associated with the highest and lowest pollutant exposures at most sites, although results varied widely by location. Model skill appeared to be better for ozone when spatial–temporal (S–T) patterns were examined, due in part to the ability of the model to reproduce much of the temporal variance associated with the diurnal photochemical cycle. At some sites the modeling even performed well in replicating the directional variability of hourly ozone despite relatively low spatial resolution. MM5–CMAQ spatial (directional) representation of 24-h-average particulate data was not good in most cases, but model skill improved somewhat when hourly data were examined. Modeling exhibited skill for sulfate at only one of nine sites using 24-h data averaged by daily resultant wind direction, at two of six sites when hourly data were averaged by direction, and at four of six sites when the combined spatial and temporal variance of sulfate was examined. Results were generally poorer for total carbon aerosol mass and total mass of particulate matter with diameter of less than 2.5 μm (PM2.5). The primary result of this study is that an S–T analysis of pollutant patterns reveals model performance insights that cannot be realized by only examining model error statistics as is typically done for regulatory applications. Use of this S–T analysis technique is recommended for better understanding model performance during longer simulation periods, especially when using grids of finer spatial resolution for applications supporting local air quality management studies. Of course, using this approach will require measuring semicontinuous fine particle data at more sites and for longer periods. [ABSTRACT FROM AUTHOR]

AB  - Abstract: The analysis of wind data collected throughout the Southern Appalachian Mountain region of the Southeastern US is presented. Data were collected at 50m above ground level on nine ridge top sites between 2002 and 2005. Monthly average wind speeds, power densities, wind sheers, and turbulence intensities, along with monthly maximum gusts, are presented. Measured annual average wind speeds are compared to AWS TrueWind predictions. Diurnal variations in wind speed are also reported. Annual wind roses for each site are presented. Annual wind speeds range from 5.5 to 7.4m/s with the highest annual average wind speeds found on ridges near the northern TN–NC border. A 20% winter and nighttime enhancement of the wind speed was observed. The prevailing wind is from the westerly directions. The estimated annual energy outputs from a small wind farm consisting of fifteen 1.5MW GE turbines range from 50 to 75MkWh, and estimated capacity factors range from 25% to 35%. This analysis suggests that ridges in the region are suitable for utility-scale wind development. [Copyright &y& Elsevier]

AB  - Abstract: Laboratory experiments suggest that strong acids promote formation of enhanced levels of secondary organic aerosol (SOA), and organic aerosols may contribute to the health impacts of fine PM. We report results from examining hourly speciated fine particle data for evidence of ambient aerosol acidity-catalyzed SOA formation, as indicated by larger increases in the concentrations of organic aerosol mass occurring on days and in locations where more acidic aerosol (lower NH4+/SO4= molar ratios) exists. Data sets from the southeastern U.S. were examined for which hourly acidity of PM2.5 aerosols could be estimated, and for which hourly organic carbon (OC) content had been measured simultaneously. Within-day organic aerosol changes during selected periods were statistically related to concurrent aerosol acidity levels estimated from nitrate-corrected ammonium-to-sulfate ratios. Data from the Look Rock, TN, TVA/IMPROVE site for mid-July to mid-August 2004 showed average compositions frequently as acidic as NH4HSO4, however, no apparent increases in OC levels with increasing aerosol acidity were observed, even when [OC] changes were compared with time-delayed aerosol acidity estimates. SEARCH network data (2003–2004) for rural Centreville, AL (CTR) and Yorkville, GA (YRK) sites were also examined. Warm-season acidity levels were higher at CTR than at YRK, and daytime levels exceeded those at night at both sites. At the YRK site no consistent positive correlations were found between changes in OC or TC levels and aerosol acidity, even with time lags up to 6 h. Aerosol acidity at this site, however, is relatively low due to nearby agricultural sources of NH3. In contrast, during selected periods from April to October 2004, at CTR, 6-h lagged OC changes were weakly correlated with daytime, nitrate-corrected NH4+/SO4= molar ratios, but distinguishing this apparent relationship from meteorological effects on measured OC levels is challenging.

AB  - Adoption of ozone technologies as Food Safety treatments in the Agri-Food Industries today is still being approached with great caution. This paper reviews selected successes in using ozone UV and advanced oxidation to enhance food safety and reduce energy costs in the Agri-Food industry. Included is a preliminary case study of utilizing ozone and chlorination in a FTNON vegetable washing system. Vegetable flotation washing systems such as the FTNON equipment produced by Noord-Oost in the Netherlands have the potential to vigorously wash sand as well as floating particulate from vegetables and fruits. With minor modifications these machines can be adapted to utilize combinations of ozone, UV and chlorination. Preliminary trials indicate plate counts are lowered with the combination treatment. Future data will need to be collected to determine the levels of chlorination required to ensure residual microbial protection without detracting from product taste and quality. When developed, these systems have the potential to enhance food safety, reduce water use and wastewater discharge amounts, reduce electrical demand and increase product shelf life.

AB  - Hemlock Woolly Adelgid ( Adelges tsugae) is spreading across forests in eastern North America, causing mortality of eastern hemlock ( Tsuga canadensis [L.] Carr.) and Carolina hemlock ( Tsuga caroliniana Engelm.). The loss of hemlock from riparian forests in Great Smoky Mountains National Park (GSMNP) may result in significant physical, chemical, and biological alterations to stream environments. To assess the influence of riparian hemlock stands on stream conditions and estimate possible impacts from hemlock loss in GSMNP, we paired hardwood- and hemlock-dominated streams to examine differences in water temperature, nitrate concentrations, pH, discharge, and available photosynthetic light. We used a Geographic Information System (GIS) to identify stream pairs that were similar in topography, geology, land use, and disturbance history in order to isolate forest type as a variable. Differences between hemlock- and hardwood-dominated streams could not be explained by dominant forest type alone as forest type yields no consistent signal on measured conditions of headwater streams in GSMNP. The variability in the results indicate that other landscape variables, such as the influence of understory Rhododendron species, may exert more control on stream conditions than canopy composition. The results of this study suggest that the replacement of hemlock overstory with hardwood species will have minimal impact on long-term stream conditions, however disturbance during the transition is likely to have significant impacts. Management of riparian forests undergoing hemlock decline should, therefore, focus on facilitating a faster transition to hardwood-dominated stands to minimize long-term effects on water quality.

AB  - Bupleurum L., with ca. 150 species, is one of the largest genera in the Apiaceae (Umbeniferae). The genus has a broad distribution in the Northern Hemisphere, and it is represented in North America by the native and possibly endemic species Bupleurum americanum I.M. Coult. & Rose, and by three introduced species: B. lancifolium Hornem., B. rotundifolium L., and B. odontites L. Here we report the occurrence of a new alien species of the genus in North America: Bupleurum gerardii All. We present a general characterization of the species and discuss the possible origin of the populations that have been found in Tennessee and Virginia. In addition, we confirm the records of B. odontites for the states of Maryland, Massachusetts and Oregon. All previous citations of B. odontites in Virginia refer to material of B. gerardii. The history of the discovery of this species in North America suggests that the treatment of sparingly naturalized taxa in floras is erratic and identifications of these species suspect.

AB  - A natural emissions inventory for the continental United States and surrounding territories is needed in order to use the US Environmental Protection Agency Community Multiscale Air Quality (CMAQ) Model for simulating natural air quality. The CMAQ air modeling system (including the Sparse Matrix Operator Kernel Emissions (SMOKE) emissions processing system) currently estimates volatile organic compound (VOC) emissions from biogenic sources, nitrogen oxide (NOx) emissions from soils, ammonia from animals, several types of particulate and reactive gas emissions from fires, as well as windblown dust and sea salt emissions. However, there are several emission categories that are not commonly treated by the standard CMAQ Model system. Most notable among these are nitrogen oxide emissions from lightning, reduced sulfur emissions from oceans, geothermal features and other continental sources, and reactive chlorine gas emissions linked with sea salt chloride. A review of past emissions modeling work and existing global emissions data bases provides information and data necessary for preparing a more complete natural emissions data base for CMAQ applications. A model-ready natural emissions data base is developed to complement the anthropogenic emissions inventory used by the VISTAS Regional Planning Organization in its work analyzing regional haze based on the year 2002. This new data base covers a modeling domain that includes the continental United States plus large portions of Canada, Mexico and surrounding oceans. Comparing July 2002 source data reveals that natural emissions account for 16% of total gaseous sulfur (sulfur dioxide, dimethylsulfide and hydrogen sulfide), 44% of total NOx, 80% of reactive carbonaceous gases (VOCs and carbon monoxide), 28% of ammonia, 96% of total chlorine (hydrochloric acid, nitryl chloride and sea salt chloride), and 84% of fine particles (i.e., those smaller than 2.5 μm in size) released into the atmosphere. The seasonality and relative importance of the various natural emissions categories are described. [ABSTRACT FROM AUTHOR]

AB  - Strickland Produce Inc., Nashville, TN, packages fresh cut salads in bags for the ready-to-eat market. Produce is sorted, cut, washed, packed in plastic bags and distributed under refrigeration. Flume water washes and transports products through the plant, and is recycled in a closed loop. Ozone was installed full-scale in 2000 for flume water treatment (200 gpm) and has provided significant improvement in plant product qualities plus savings in water, labor, and plant effluent costs for the past six years. With chlorine treatment alone, the flume water quickly became discolored, laden with organic residues, and needed to be replaced every 2-3 hours. With the ozone treatment, flume water is replaced once daily, allowing for at least a 60% flume water savings. Of even more significance are the labor savings resulting from less frequent changing of spent flume water. Costs for ozonation equipment were recovered in less than two years.

AB  - The Tennessee Valley Authority (TVA) and the Department of Energy (DOE) have partnered to pursue the use of down-blended, off-specification highly-enriched uranium (HEU) in TVA reactors. Approximately 46 MTU of off-spec HEU are being dispositioned as BLEU fuel in TVA's reactors with another 15 MTU potentially available. Participation in this agreement required a significant up-front investment by TVA and the assumption of higher risk due to the different fabrication methods required for the BLEU fuel. The potential for significant cost savings that could be shared between TVA and the US Treasury also existed. This paper describes the BLEU program and the challenges TVA and DOE have overcome via implementation through TVA's contract with AREVA and AREVA's subcontractor, Nuclear Fuel Services.

AB  - A natural emissions inventory for the continental United States and surrounding territories is needed in order to use the US Environmental Protection Agency Community Multiscale Air Quality (CMAQ) Model for simulating natural air quality. The CMAQ air modeling system (including the Sparse Matrix Operator Kernel Emissions (SMOKE) emissions processing system) currently estimates non-methane volatile organic compound (NMVOC) emissions from biogenic sources, nitrogen oxide (NOx) emissions from soils, ammonia from animals, several types of particulate and reactive gas emissions from fires, as well as sea salt emissions. However, there are several emission categories that are not commonly treated by the standard CMAQ Model system. Most notable among these are nitrogen oxide emissions from lightning, reduced sulfur emissions from oceans, geothermal features and other continental sources, windblown dust particulate, and reactive chlorine gas emissions linked with sea salt chloride. A review of past emissions modeling work and existing global emissions data bases provides information and data necessary for preparing a more complete natural emissions data base for CMAQ applications. A model-ready natural emissions data base is developed to complement the anthropogenic emissions inventory used by the VISTAS Regional Planning Organization in its work analyzing regional haze based on the year 2002. This new data base covers a modeling domain that includes the continental United States plus large portions of Canada, Mexico and surrounding oceans. Comparing July 2002 source data reveals that natural emissions account for 16% of total gaseous sulfur (sulfur dioxide, dimethylsulfide and hydrogen sulfide), 44% of total NOx, 80% of reactive carbonaceous gases (NMVOCs and carbon monoxide), 28% of ammonia, 96% of total chlorine (hydrochloric acid, nitryl chloride and sea salt chloride), and 84% of fine particles (i.e., those smaller than 2.5 μm in size) released into the atmosphere. The seasonality and relative importance of the various natural emissions categories are described. [ABSTRACT FROM AUTHOR]

AB  - A recent version (4.6) of the Community Multiscale Air Quality (CMAQ) model was used as the basis for testing model revisions for including reactions involving chlorine (HCl, ClNO2) and reduced sulfur (dimethylsulfide, or DMS, and H2S) species not normally treated in the CB05 gas chemical mechanism and cloud chemistry module. Model chemistry revisions were based on published reaction kinetic data and a recent cloud chemistry model that includes heterogeneous reactions of organic sulfur compounds. Testing of the revised model was conducted using a recently enhanced data base of natural emissions that includes ocean and continental sources of DMS, H2S, chlorinated gases and lightning NOx for the continental United States and surrounding regions. Results using 2002 meteorology and emissions indicated that most simulated chemical and aerosol species exhibit the expected seasonal variations in grid-average surface concentrations. Ozone exhibits a winter and early spring maximum - reasonably consistent with ozone data and model results produced by others - in a pattern that reflects the influences of atmospheric dynamics and pollutant background levels imposed on the CMAQ simulation by boundary conditions derived from a global model. A series of experimental model simulations reveals that the addition of gas phase organic sulfur chemistry leads to sulfate aerosol increases over most of the continental United States. Modifications to the cloud chemistry module result in widespread decreases in SO2 across the modeling domain and a mix of sulfate increases and decreases. Most cloud-mediated sulfate increases occurred over the Pacific Ocean (up to about 0.1 μgm-3) and at slightly lesser amounts over and downwind from the Gulf of Mexico (including portions of the Eastern US). Variations in the chemical response are due to the link between DMS/H2S and their byproduct SO2, the heterogeneity of cloud cover and precipitation (precipitating clouds act as net sinks for SO2 and sulfate), and the persistence of cloud cover (the largest relative sulfate increases occurred over the persistently cloudy Gulf of Mexico and western Atlantic Ocean). Overall, the addition of organic sulfur chemistry increased surface hourly sulfate levels by as much as 1-2 μgm-3 in selected grid cells. The added chemistry produced significantly less sulfate in the vicinity of high SO2 emissions (e.g., wildfires), perhaps in response to lower OH from competing reactions with DMS and its derivatives. Simulated surface levels of DMS compare favorably with published observations made in the marine boundary layer. However, DMS derivatives are lower than observed implying either less chemical reactivity in the model or a low bias in the boundary conditions for DMS derivatives such as dimethylsulfoxide. The sensitivity of sulfate to cloud cover and the aqueous sulfate radical is also explored. This revised version of CMAQ provides a tool for more realistically evaluating the influence of natural emissions on air quality. [ABSTRACT FROM AUTHOR]

AB  - This paper, prepared by the Climate Change Technology Subcommittee, a subcommittee of the Power and Energy Society Energy Development and Power Generation Committee, identifies key technical issues facing the electric power industry, related to global climate change. The technical challenges arise from: 1) impacts on system operating strategies, configuration, and expansion plans of emission-reducing technologies; 2) power infrastructure response to extreme weather events; 3) effects of government policies including an expanded use of renewable and alternative energy technologies; and 4) impacts of market rules on power system operation. Possible lessons from other industries' responses to climate change are explored. [ABSTRACT FROM AUTHOR]

AB  - Isoprene-derived epoxydiols (IEPOX) are identified in ambient aerosol samples for the first time, together with other previously identified isoprene tracers (i.e., 2-methyltetrols, 2-methylglyceric acid, C5-alkenetriols, and organosulfate derivatives of 2-methyltetrols). Fine ambient aerosol collected in downtown Atlanta, GA and rural Yorkville, GA during the 2008 August Mini-Intensive Gas and Aerosol Study (AMIGAS) was analyzed using both gas chromatography/quadrupole mass spectrometry (GC/MS) and gas chromatography/time-of-flight mass spectrometry (GC/TOFMS) with prior trimethylsilylation. Mass concentrations of IEPOX ranged from ∼1 to 24 ng m-3 in the aerosol collected from the two sites. Detection of particle-phase IEPOX in the AMIGAS samples supports recent laboratory results that gas-phase IEPOX produced from the photooxidation of isoprene under low-NOx conditions is a key precursor of ambient isoprene secondary organic aerosol (SOA) formation. On average, the sum of the mass concentrations of IEPOX and the measured isoprene SOA tracers accounted for about 3% of the organic carbon, demonstrating the significance of isoprene oxidation to the formation of ambient aerosol in this region.

AB  - Can we use lagged values of major stock market indices to provide useful predictions as a standard vector autoregressive model? Underlying this application, of course, is the question of finding a vector autoregressive model which makes accurate and efficient forecasts. In this paper, we use the Genetic Algorithm with information complexity criteria as the fitness function to drive subset selection and parameter estimation. In the testing period when the target index lost more than 15%, the identified subset VAR model gained over 17%. The prediction error bands built around the forecasts are half as wide as those obtained by the saturated model. Using both simulation and application studies, we present evidence that even when the typical regression assumptions seem to be met, the VAR model is misspecified. [ABSTRACT FROM AUTHOR]

AB  - As part of a larger effort to improve water quality in the Little River watershed, we installed and monitored 45 erosion pins on 12 banks of tributaries of this east Tennessee river. Here, we examine changes in exposure of individual erosion pins and compare measurements made after 2.5 years to those made at the end of the first year (2007). No stream bank remained the same. Changes at individual pins ranged from 32.2 cm eroded to 2 cm deposited (deeper deposits remain unmeasured), with a mean bank-averaged erosion rate of 2.4 cm/yr. First-year results illustrated trends seen later-mean losses 1 to 2 cm/yr per bank, considerable variation, greatest losses on lower banks, and active subaerial erosion-but did not predict trends for individual pins or banks. At half of the sites, rates of change measured at 2.5 years exceeded those measured after the first year. (English) [ABSTRACT FROM AUTHOR]

Aquí, examinamos cambios en exposición en puntos individuales de erosión y comparamos las medidas realizadas después de 2.5 años a las realizadas a finales del primer año (2007). Ningún banco de cuenca se mantuvo igual. Los cambios en los puntos individuales fluctuaron de 32.2 cm erosionados a 2 cm en el depósito (los depósitos más profundos se mantienen sin medir), con una media promedio en la tasa de erosión en el banco de 2.4 cm al año. Los resultados del primer año ilustraron patrones vistos más tarde—pérdidas medias ≈1 a 2 cm al año por banco, variación considerable, las pérdidas mayores en la parte inferior de los bancos, y erosión sub-aérea activa—pero no se predijeron patrones para puntos o bancos individuales. En la mitad de los lugares, las tasas de cambio medidas en 2.5 años excedieron las medidas después del primer año. (Spanish) [ABSTRACT FROM AUTHOR]

AB  - This study provides quantitative ecological targets for restoring degraded peat-based Carolina Bays in the Carolina Flatwoods Ecoregion. Cluster analysis of vegetation data from three Carolina Bay reference sites in Bladen County, North Carolina, indicated four plant communities present: pond pine (Pinus serotina) woodland, non-riverine swamp forest dominated by swamp gum (Nyssa biflora), high pocosin dominated by evergreen shrubs with scattered pond pine, and bay forest dominated by loblolly bay (Gordonia lasianthus). We classified bay soils according to surface organic layer thickness (OLT) into mineral, histic, shallow organic, and deep organic types. We monitored the water table of each soil type in one bay throughout one growing season. The soil types with corresponding water table regimes were: mineral (9.4 cm mean OLT with a rooting zone water table [RZWT] 39% of the monitoring period), histic (27.5 cm OLT and 76% RZWT), shallow organic (63.9 cm OLT and 84% RZWT), and deep organic (102.5 cm OLT and 57% RZWT). Pearson residual analysis and correspondence analysis revealed that pond pine woodland was positively associated with mineral and histic soils, non-riverine swamp forest with shallow organic soil, bay forest with deep organic soil, and high pocosin with deep organic soil. We concluded that peat-based Carolina Bay restoration in the Carolina Flatwoods Ecoregion should be gauged against reference data which suggests: 1) pond pine woodland be established on mineral and histic soils; 2) non-riverine swamp forest be established on shallow organic soils; and 3) high pocosin and bay forest be established on deep organic soils.

AB  - Approximately 390 native North American crayfish species are known, representing nearly two-thirds of the world's crayfish fauna. The majority of these species occur in the southeastern United States. North Carolina supports a substantial proportion of that diversity with 41 described indigenous crayfish species, 12 of which are endemic, and 3 introduced species, many of which are of significant conservation interest. In the late 1990s, the North Carolina Wildlife Resources Commission (NCWRC) began a focused effort to inventory and establish baselines for monitoring populations of both native stream-dwelling and burrowing crayfishes and invasive non-native species. During 2004-2005, that effort was completed for the Hiwassee, Little Tennessee, Savannah, French Broad, Watauga, New, Catawba, and Broad river basins in western North Carolina. Twenty-four stream-dwelling species and 5 burrowing species were collected from 199 stream sites and 58 burrowing sites. New records for many species, including a new river basin record for Cambarus reduncus (Sickle Crayfish), and new county records for C. howardi (Chattahoochee Crayfish), C. dubius (Upland Burrowing Crayfish), and C. nodosus (Knotty Burrowing Crayfish), were determined during these surveys. Small range expansions were documented for Orconectes virilis (Virile Crayfish; not native to North Carolina) and for Procambarus acutus (White River Crawfish; introduced outside its native range in North Carolina). We failed to detect the non-native O. rusticus (Rusty Crayfish), and P. clarkii (Red Swamp Crawfish) at or near previously reported localities. Observations of life-history traits, such as reproductive condition, fecundity, and habitat use were recorded. Specimens were also provided to crayfish taxonomists to help resolve certain taxonomic problems and to assist in the completion of new species descriptions. Data collected during this and previous NCWRC inventories, as well as data obtained from the North Carolina State Museum of Natural Sciences, North Carolina Division of Water Quality, Ohio State University, and other cooperators, were incorporated into a detailed GIS database. This database was used to identify data gaps to guide sampling efforts and to assess species and population status. In the future, this GIS database should provide a useful tool in monitoring the status of native crayfish populations and the spread of invasive species, and informing conservation and management decision making.

AB  - The relative roles of natural and anthropogenic sources in determining ozone and fine particle concentrations over the continental United States (U.S.) are investigated using an expanded emissions inventory of natural sources and an updated version of the Community Multiscale Air Quality (CMAQ) model. Various 12-month CMAQ simulations for the year 2002 using different sets of input emissions data are combined to delineate the contributions of background pollutants (i.e., model boundary conditions), natural emissions, anthropogenic emissions, as well as the specific impacts of lightning and wildfires. Results are compared with observations and previous air quality model simulations. Wildfires and lightning are both identified as contributing significantly to ozone levels with lightning NOx adding as much as 25-30 ppbV (or up to about 50%) to surface 8-h average natural O3 mixing ratios in the southeastern U.S. Simulated wildfire emissions added more than 50 ppbV (in some cases >90%) to 8-h natural O3 at several locations in the west. Modeling also indicates that natural emissions (including biogenic, oceanic, geogenic and fires) contributed ≤40% to the annual average of total simulated fine particle mass over the eastern two-thirds of the U.S. and >40% across most of the western U.S. Biogenic emissions are the dominant source of particulate mass over the entire U.S. and wildfire emissions are secondary. Averaged over the entire modeling domain, background and natural ozone are dominant with anthropogenically derived ozone contributing up to a third of the total only during summer. Background contributions to fine particle levels are relatively insignificant in comparison. Model results are also contrasted with the U.S. Environmental Protection Agency (EPA) default values for natural light scattering particle concentrations to be used for regional haze regulatory decision-making. Regional differences in EPA guidance are not supported by the modeling and EPA uncertainty estimates for default values are far smaller than the modeled variability in natural particle concentrations.

AB  - The power transmission conductor system consists of: the aluminum conductor, the steel-core supporting material, and the splice connector. The splice connector connects the aluminum conductor to form a continuing current transmission line. The splice connector region of a conductor system is more sensitive to material aging during service. This is due to the material discontinuity and the crimped connector's forming mechanism. The objective of this project is to develop a protocol to evaluate the integrity of a full tension single-stage splice connector (SSC) assembly operated at high temperature. The project focuses on thermal mechanical testing, thermal cycling simulation and the effective lifetime of the SSC system. The investigation indicates that thermal cycling temperature and frequency, conductor cable tension loading, and the compressive residual stress field within a SSC system have significant impact on SSC integrity and its associated effective lifetime. The developed governing equation and its application to assure the adequate service life of transmission lines are also discussed in the paper. <query-in-text/> [ABSTRACT FROM AUTHOR]

AB  - ndrews, Danielle M., Christopher D. Barton, Randall K. Kolka, Charles C. Rhoades, and Adam J. Dattilo, 2011. Soil and Water Characteristics in Restored Canebrake and Forest Riparian Zones. Journal of the American Water Resources Association (JAWRA) 47(4):772-784. DOI: 10.1111/j.1752-1688.2011.00555.x Abstract:  The degradation of streams has been widespread in the United States. In Kentucky, for instance, almost all of its large streams have been impounded or channelized. A restoration project was initiated in a channelized section of Wilson Creek (Nelson Co., Kentucky) to return its predisturbance meandering configuration. A goal of the project was to restore the native riparian corridor with giant cane and bottomland forest species. The objective of this study was to evaluate the use of giant cane in riparian restoration and to compare water quality and soil attributes between restored cane and forested communities. Comparison of data to replicated sites of similar size in undisturbed upstream areas (control) was also examined to evaluate restoration success. Vegetation establishment was initially hindered by frequent flooding in 2004, but mean survival was good after two growing seasons with rates of 80 and 61% for forest and cane plots, respectively. Results showed an improvement in stream water quality due to restoration activities. Significant differences between the cane and forested plots in shallow groundwater dissolved oxygen, NO3−-N, NH4+-N, and Mn concentrations suggest that soil redox conditions were not similar between the two vegetation types. Retention and transformation of carbon (C) and nitrogen (N) within the restored riparian system also differed by vegetation treatment; however, both communities appeared to be advancing toward conditions exhibited in the control section of Wilson Creek.

AB  - In this study, we evaluate several forms of both Akaike-type and Information Complexity (ICOMP)-type information criteria, in the context of selecting an optimal subset least squares ratio (LSR) regression model. Our simulation studies are designed to mimic many characteristics present in real data - heavy tails, multicollinearity, redundant variables, and completely unnecessary variables. Our findings are that LSR in conjunction with one of the ICOMP criteria is very good at selecting the true model. Finally, we apply these methods to the familiar body fat data set.

AB  - Pityopsis ruthii is an endangered herbaceous perennial species from the United States. In vitro multiplication of this species can be valuable for germplasm conservation. Flower receptacles of P. ruthii were cultured on Murashige and Skoog medium (MS) supplemented with 11.4 μM indole-3-acetic acid (IAA) in combination with 2.2, 4.4 or 8.8 μM 6-benzyladenine (BA). Shoots were visible within 14-28 days and three plants were successfully rooted on MS medium supplemented with 5.7 μM IAA. A two tailed t-test for paired-variates revealed that shoot regeneration on MS medium amended with 11.4 μM IAA and 2.2 μM BA was significantly higher ( P < 0.05) than on other treatments. Leaf explants were also cultured on MS not supplemented with growth regulators or supplemented with 11.4 μM IAA in combination with 0, 2.2, 4.4 or 8.8 μM BA. Shoots were visible within 21-35 days and one plant was successfully rooted on MS medium supplemented with 5.4 μM NAA. Shoot regeneration on MS medium augmented with 11.4 μM IAA and 2.2 μM BA was significantly higher ( P < 0.05) than the other treatments according to analysis of variance (ANOVA) with a rank transformation. Hyperhydricity and rooting of shoots was problematic for explants derived from flower receptacles and leaf tissue, but viable plants were regenerated using both explants sources indicating the potential role for micropropagation in the ex situ conservation of the species.

AB  - Abstract: We evaluate the simulations of SO2 and sulfate using the Community Multiscale Air Quality model (CMAQ) version 4.6 with the observations over the United States in 2002. MM5 was used for meteorological simulations. While the general seasonal cycles of SO2 and sulfate are simulated well by the model, we find significant systematic biases in the summer. The model low bias in sulfate is considerably more severe than the model bias in SO2. Both ACM and RADM schemes are used in the model to test the sensitivities of simulated sulfate to cloud processing. We carry out detailed modeling analysis and diagnostics for July 2002. Compared to satellite observations of cloud liquid water path, CMAQ cloud modules greatly overestimates convective (sub-grid) precipitating clouds, leading to large overestimation of sulfate wet scavenging. Limiting convective precipitating cloud fraction in the cloud modules to <10% and hence significantly reducing wet scavenging lead to much improved agreement between simulated and observed sulfate. The average lifetime of sulfate in the model increases from 1–2 days to 3–4 days for July. We show that a potential model problem of excessive wet scavenging of sulfate does not necessarily lead to apparent problems in model simulations of sulfate wet deposition rate compared to surface observations. In general, there is still a lack of direct observational constraints from air quality monitoring measurements on model simulated cloud processing of SO2 and sulfate. [Copyright &y& Elsevier]

AB  - Normality is the most frequently required assumption for statistical techniques. Thus, evaluation of the normality assumption is the first step of many statistical analyses. Although there are many normality tests in the literature, none dominate for all conditions. This paper introduces a novel normality test, and its performance is compared with some of the other normality tests via a Monte Carlo simulation study. Tests are evaluated according to the Type I error and Power. [ABSTRACT FROM AUTHOR]

AB  - Abstract: Throughfall and litterfall represent two major pathways which comprise the bulk of the mercury that reaches the forest floor. In an effort to quantify total mercury deposition to forests, throughfall and litterfall samples were collected at three elevations in the Great Smoky Mountains National Park (GSMNP) between April and November in 2008 and 2009. The mean (±standard error) volume-weighted throughfall total mercury concentration across all three sites ranged from 13.62 ng L−1 (±0.86) to 18.23 ng L−1 (±0.77) with a slight trend of higher throughfall mercury concentration at the high elevation spruce-fir sites relative to the low elevation mixed-hardwood site. The mean (±standard error) throughfall total mercury deposition across all sites ranged from 2.07 μg m−2 (±0.09) to 4.09 μg m−2 (±0.38). Mean (±standard error) mass-weighted litterfall concentration ranged from 37.2 ng g−1 (±1.36) to 62.87 ng g−1 (±1.94) and statistically higher (p = 0.02, p < 0.05) mean concentrations were observed at the higher elevation sites. The mean (±standard error) litterfall mercury deposition across all three sites ranged from 10.34 μg m−2 (±0.69) to 29.30 μg m−2 (±0.44). Although, no statistically (p = 0.05, p < 0.05) significant difference was observed between the sites for either throughfall or litterfall deposition, both increased from 2008 to 2009 at the lower elevation site. Mean litterfall deposition (17.93 μg m−2) dominated Hg input for the two years studied over mean throughfall deposition (3.20 μg m−2). Meanwhile, the mean throughfall concentration (17.8 ng L−1) dominated the mean open area precipitation input (6.03 ng L−1) at the high elevation site, suggesting evidence for a dry deposition component from the forest canopy. While the study was limited in scope, the results do provide some basic data that adds to understanding Hg inputs to the terrestrial ecosystem in general and in the GSMNP specifically.

AB  - Bluemask darters ( Etheostoma akatulo) were sampled from the four drainages where extant populations of this narrowly endemic freshwater fish are known to exist. Population genetic diversity and structure were assessed at 10 microsatellite loci. All populations exhibited low levels of genetic variation, with expected heterozygosity ranging from 0.2 to 0.35. Significant population subdivision was found among most tributaries, and genetic divergence was strongly correlated with geographic distance. Bayesian population assignment and pairwise population differentiation measures both identified a lack of differentiation between E. akatulo populations inhabiting Cane Creek and the Caney Fork. This observation reduced the number of distinct breeding populations of this species to three. We also used approximate Bayesian computation to compare three models of demographic history in this species. A constant population size model was favored over models that included historic or recent population reductions. Our results suggest that impoundment of the Caney Fork and its tributaries, by completion of Great Falls Dam in 1916, was not responsible for the reduced genetic diversity in the sampled populations. Given the low levels of genetic diversity within populations and the limited geographic distribution, future conservation efforts should seek to maximize available habitat while simultaneously limiting the influences of anthropogenic stressors in the system.

AB  - In order for habitat restoration in regulated rivers to be effective at large scales, broadly applicable frameworks are needed that provide measurable objectives and contexts for management. The Ecological Limits of Hydrologic Alteration (ELOHA) framework was created as a template to assess hydrologic alterations, develop relationships between altered streamflow and ecology, and establish environmental flow standards. We tested the utility of ELOHA in informing flow restoration applications for fish and riparian communities in regulated rivers in the Upper Tennessee River Basin (UTRB). We followed the steps of ELOHA to generate univariate relationships between altered flows and ecology within the UTRB. By comparison, we constructed multivariate models to determine improvements in predictive capacity with the addition of non-flow variables. We then determined whether those relationships could predict fish and riparian responses to flow restoration in the Cheoah River, a regulated system within the UTRB. Although ELOHA provided a robust template to construct hydrologic information and predict hydrology for ungaged locations, our results do not suggest that univariate relationships between flow and ecology (step 4, ELOHA process) can produce results sufficient to guide flow restoration in regulated rivers. After constructing multivariate models, we successfully developed predictive relationships between flow alterations and fish/riparian responses. In accordance with model predictions, riparian encroachment displayed consistent decreases with increases in flow magnitude in the Cheoah River; however, fish richness did not increase as predicted 4 years after restoration. Our results suggest that altered temperature and substrate and the current disturbance regime may have reduced opportunities for fish species colonization. Our case study highlights the need for interdisciplinary science in defining environmental flows for regulated rivers and the need for adaptive management approaches once flows are restored.

AB  - The Mississippi Silverside, Menidia audens, was first encountered in Kentucky Reservoir, the most downstream reservoir on the mainstem Tennessee River, in 1991. Over the next 19 years, it invaded all nine mainstem reservoirs, consisting of 1049 river km, and two tributary reservoirs, at an average rate of 55 km per year. This species was first encountered in Barkley Reservoir, the lowermost reservoir of the Cumberland River, in 1990, and has since established populations throughout at least 402 river km of the mainstem Cumberland River. Following the first record of M. audens in an unimpounded section of a Tennessee River tributary during 1998, 1048 sites were sampled throughout the Tennessee River system and this species was documented in only eight additional unimpounded tributaries, indicating aversion to lotic systems. Following the invasion of Tennessee River reservoirs by M. audens, mean abundance of the Brook Silverside, Labidesthes sicculus, linearly decreased with time. Electrofishing catch per unit effort (CPUE) data indicate that 14 years after sympatry with M. audens, L. sicculus were undetectable or occurred at extremely low densities in reservoirs. Reservoir populations of L. sicculus exhibited cyclic variation in abundance among years prior to the presence of M. audens. The observed range of electrofishing CPUE of L. sicculus before invasion by M. audens (n = 3865) was significantly different (P, 0.001) than the observed range following the presence of M. audens (n = 3975). After detection of M. audens, electrofishing CPUE of L. sicculus decreased and the range of variation from year to year diminished. Data from Cumberland River reservoirs showed similar patterns of displacement.5 [ABSTRACT FROM AUTHOR]

AB  - Dry fly ash disposal involves dropping ash from a truck and the movement of a heavy grader or similar vehicle across the ash surface. These operations are known to produce fugitive particulate emissions that are not readily quantifiable using standard emission measurement techniques. However, there are numerous situations--such as applying for a source air permit--that require these emissions be quantified. Engineers traditionally use emission factors (EFs) derived from measurements of related processes to estimate fly ash disposal emissions. This study near a dry fly ash disposal site using state-of-the-art particulate monitoring equipment examines for the first time fugitive emissions specific to fly ash handling at an active disposal site. The study measured hourly airborne mass concentrations for particles smaller than 2.5 μm (PM2.5) and 10 μm (PM10) along with meteorological conditions and atmospheric turbidity at high temporal resolution to characterize and quantify fugitive fly ash emissions. Fugitive fly ash transport and dispersion were computed using the on-site meteorological data and a regulatory air pollutant dispersion model (AERMOD). Model outputs coupled with ambient measurements yielded fugitive fly ash EFs that averaged 96 g Mg−1(of ash processed) for the PMcfraction (=PM10- PM2.5) and 18 g Mg−1for PM2.5. Median EFs were much lower due to the strongly skewed shape of the derived EF distributions. Fugitive EFs from nearby unpaved roads were also characterized. Our primary finding is that EFs for dry fly ash disposal are considerably less than EFs derived using US Environmental Protection Agency AP-42 Emissions Handbook formulations for generic aggregate materials. This appears to be due to a large difference (a factor of 10+) between fugitive vehicular EFs estimated using the AP-42 formulation for vehicles driving on industrial roads (in this case, heavy slow-moving grading equipment) and EFs derived by the current study.

While seasonal changes in microbial community composition were observed, the significant ( P = 0.001) changes in bacterial and archaeal communities were consistent with variations in ammonium concentration. Phylogenetic analysis of 16S rRNA gene sequences revealed an increase of potential ammonium-oxidizing bacteria (AOB), Nitrosomonas, Nitrosococcus, Planctomycetes, and OD1, in samples with elevated ammonium concentration. Other bacteria, such as Nitrospira, Nitrococcus, Nitrobacter, Thiobacillus, ε-Proteobacteria, Firmicutes, and Acidobacteria, which play roles in nitrification and denitrification, were also detected. The AOB oxidized 56 % of the ammonium with the concomitant increase in nitrite and ultimately nitrate in the trickling filters at the beginning of the treatment system. Thermoprotei within the phylum Crenarchaeota thrived in the splitter box and especially in zero-valent iron extraction trenches, where an additional 25 % of the ammonium was removed. The potential ammonium-oxidizing Archaea (AOA) ( Candidatus Nitrosocaldus) were detected towards the downstream end of the treatment system. The design of an integrated treatment system consisting of trickling filters, zero-valent iron reaction cells, settling pond, and anaerobic wetlands was efficient for the biological removal of ammonium and several other contaminants from wastewater generated at a coal burning power plant equipped with selective catalytic reducers for nitrogen oxide removal.

AB  - Etheostoma boschungi (Slackwater Darter) is a migratory fish species endemic to tributaries of the Tennessee River. Although the distribution of this species was historically disjunct and limited, current data suggest that the species is suffering a decline in both distribution and abundance, resulting in critically low population levels. Data collected over a 10-year period demonstrate an approximate 45 % distributional decline relative a previous survey. In addition, numbers of individuals collected at breeding sites has also declined during this time period. Detectability for sites with repeated sampling effort suggest that even where the species persists, it may be in numbers too low for detection with just one effort. Factors affecting persistence of Slackwater Darters may include passage barriers, such as culverts and loss of connectivity to flooded breeding sites due to channel incision, but data on the effects of these environmental factors are largely lacking.

AB  - The largest environmental release of coal ash in US history occurred in December 2008 with the failure of a retention structure at the Tennessee Valley Authority Kingston Fossil Fuel Plant in East Tennessee. A byproduct of coal-burning power plants, coal ash is enriched in metals and metalloids such as selenium and arsenic with known toxicity to fish embryonic and larval life stages. The early development of fish embryos and larvae during contact exposures to river bottom sediments containing up to 78 % coal ash from the Kingston spill was examined in 7-day laboratory tests with the fathead minnow ( Pimephales promelas). No significant effects were observed in hatching success, incidences of developmental abnormalities, or embryo-larval survival. Results suggest that direct exposures to sediment containing residual coal ash from the Kingston ash release may not present a significant risk to fish eggs and larvae in waterways affected by the coal ash spill.

AB  - Pityopsis ruthii is an endangered species endemic to the Hiwassee and Ocoee Rivers in Tennessee. As part of a recovery effort focused on P. ruthii, vegetative propagation and in vitro multiplication and seed germination techniques were developed. Plants were vegetatively propagated using greenhouse stock plants and wild-collected stems. Rooting occurred with and without auxin treatments but was greatest when 0.1% indole-3-butyric acid (IBA) talc was applied to the vegetative cuttings; rooting was lowest when flowering stems were used. Pro-Mix BX substrate provided the most consistent rooting. In vitro multiplication was accomplished by the removal of lateral shoots from in vitro-grown plants that were rooted on Murashige and Skoog (MS0) basal medium with 270 clones produced from a single individual after 4 months. Nineteen clones were transplanted and secured with bonded fiber matrix into their natural habitat and 14 survived for 1 year. To avoid genetic swamping of native populations with the introduction of large numbers of genetically identical individuals through clonal propagation, seed-based propagation efforts were explored. Open-pollinated seeds were collected, disinfested and germinated, and seedlings established on MS medium. Seeds were submersed in 70% ethanol for 1 minute and briefly flamed. Seeds were surface-sterilized in a range [10% to 50% (v/v)] Clorox® bleach solutions with vigorous shaking for 20 minutes, rinsed three times in sterile water, and germinated on MS0. Removal of pappus from seeds was required for successful disinfestations, but the bleach concentration was not critical. Successful propagation is a step toward the conservation and recovery of P. ruthii and should allow future reintroduction projects. [ABSTRACT FROM AUTHOR]

AB  - The industry standard currently accepted method for assessing the resistance of concrete to penetration of chloride ions is commonly known as the rapid chloride permeability (RCP) test. The test is time-consuming and laborious and the user must be extremely careful to ensure accuracy, making it problematic for inclusion as a performance variable in a concrete specification. A potential alternative to the RCP test is the surface resistivity (SR) test, a method that is dramatically easier, faster, and requires far less special care than the RCP test. The research reported herein was directed toward determining a correlation between RCP and SR test measurements for Tennessee bridge deck concrete (based on cylinders collected from concrete bridge decks being constructed across the state) and evaluating the appropriateness of the SR test as an alternative to the RCP test for inclusion in a specification for bridge deck concrete. Results of the testing showed a clear correlation between the two methods and identified potential limits for possible inclusion as a performance requirement in a specification.

AB  - The weathering of coal combustion products (CCPs) in a lotic environment was assessed following the Tennessee Valley Authority (Kingston, TN) fly ash release of 2008 into surrounding rivers. Sampled materials included stockpiled ash and sediment collected from 180 to 880 days following the release. Total recoverable concentrations of heavy metals and metalloids in sediment were measured, and percent ash was estimated visually or quantified by particle counts. Arsenic and selenium in sediment were positively correlated with percent ash. For samples collected 180 days after the release, total concentrations of trace elements downstream of the release were greater than reference levels but less than concentrations measured in stockpiled ash. Total concentrations of trace elements remained elevated in ash-laden sediment after almost 2.5 years. A sequential extraction procedure (SEP) was used to speciate selected fractions of arsenic, copper, lead, nickel, and selenium in decreasing order of bioavailability. Concentrations of trace elements in sequentially extracted fractions were one to two orders of magnitude lower than total recoverable trace elements. The bulk of sequentially extractable trace elements was associated with iron-manganese oxides, the least bioavailable fraction of those measured. By 780 days, trace element concentrations in the SEP fractions approached reference concentrations in the more bioavailable water soluble, ion exchangeable, and carbonate-bound fractions. For each trace element, the percentage composition of the bioavailable fractions relative to the total concentration was calculated. These SEP indices were summed and shown to significantly decrease over time. These results document the natural attenuation of leachable trace elements in CCPs in river sediment as a result of the loss of bioavailable trace elements over time. [ABSTRACT FROM AUTHOR]

AB  - ABSTRACT Ecological limit functions relating streamflow and aquatic ecosystems remain elusive despite decades of research. We investigated functional relationships between species richness and changes in streamflow characteristics at 662 fish sampling sites in the Tennessee River basin. Our approach included the following: (1) a brief summary of relevant literature on functional relations between fish and streamflow, (2) the development of ecological limit functions that describe the strongest discernible relationships between fish species richness and streamflow characteristics, (3) the evaluation of proposed definitions of hydrologic reference conditions, and (4) an investigation of the internal structures of wedge-shaped distributions underlying ecological limit functions. Twenty-one ecological limit functions were developed across three ecoregions that relate the species richness of 11 fish groups and departures from hydrologic reference conditions using multivariate and quantile regression methods. Each negatively sloped function is described using up to four streamflow characteristics expressed in terms of cumulative departure from hydrologic reference conditions. Negative slopes indicate increased departure results in decreased species richness. Sites with the highest measured fish species richness generally had near-reference hydrologic conditions for a given ecoregion. Hydrology did not generally differ between sites with the highest and lowest fish species richness, indicating that other environmental factors likely limit species richness at sites with reference hydrology. Use of ecological limit functions to make decisions regarding proposed hydrologic regime changes, although commonly presented as a management tool, is not as straightforward or informative as often assumed. We contend that statistical evaluation of the internal wedge structure below limit functions may provide a probabilistic understanding of how aquatic ecology is influenced by altered hydrology and may serve as the basis for evaluating the potential effect of proposed hydrologic changes.

AB  - In December 2008, 4.1 million cubic meters of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary rather than aqueous exposure, tissue-based toxicity thresholds for Se are currently being considered. The proposed threshold concentrations range between 4 μg/g and 9 μg/g Se (dry wt.) in whole body fish, with a proposed fillet threshold of 11.8 μg/g. In the present study, the authors examined the spatial and temporal trends in Se bioaccumulation and examined the relationship between the Se content in fillets and in whole bodies of fish collected around the Kingston spill site to determine whether Se bioaccumulation was a significant concern at the ash spill site. Whereas Se concentrations in fish (whole bodies and fillets) were elevated at sampling locations affected by the Kingston ash spill relative to reference locations, concentrations do not appear to be above risk thresholds and have not been increasing over the 5-yr period since the spill. These findings are not only relevant to guiding the human health and ecological risk assessments at the Kingston ash spill site, but because of current national discussions on appropriate guidelines for Se in fish as well for the disposal of coal combustion wastes, the results are also relevant to the general understanding of Se bioaccumulation in contaminated water bodies.

AB  - Studies related to the durability of bridge deck concrete in the state of Tennessee have been ongoing at the University of Tennessee for the past decade. The most recent phase of this research began in the fall of 2009 with a focus on developing a criteria and methodology to assess the durability of bridge deck concrete in Tennessee. The concrete's resistance to chloride ion penetration was used to evaluate durability. This resistance was measured by two test methods: the surface resistivity (SR) test and the rapid chloride ion penetration (RCP) test. Current guidelines set forth by the Tennessee Department of Transportation (TDOT) require that a Class D concrete mixture be placed on all bridge deck applications. The SR and RCP tests have been performed on Class D concrete cylinders from various bridge deck placements across the state for the past 2.5 years. The Class D mixture consists of 75% cement and 25% fly ash (generally Class F). Results indicate that the current concrete mixture fails to adequately resist chloride ion penetration at satisfactory levels. Ternary blend concrete mixtures, so defined when the mixture contains three different types of cementitious materials, have been found to offer benefits to both the strength and durability of concrete. Thus, it was decided to propose a ternary blend concrete mixture. While ternary blends are not currently prohibited by TDOT, the Class D concrete mixtures currently being placed on bridge decks are, as noted, binary mixtures. Ternary blend laboratory samples were created to compare SR and RCP values to the typical Class D mixtures. Results from the tests, as well as results reported in technical literature, indicate that ternary blend mixtures have significantly better resistance to chloride ion penetration than the typical Class D mixtures, indicating improvement in concrete durability with such a mixture.

AB  - The underfrequency load shedding (UFLS) mostly used in industry is a decentralized deterministic scheme designed to shed a prespecified amount of load after a predetermined time delay. It sheds the same amount of load from the same location irrespective of how fast the frequency drops and without consideration of the disturbance location or dip in bus voltage. Recent studies focused on adaptive UFLS, but these studies are still based on software simulation. This study presents an implementation of a real-time centralized adaptive UFLS scheme using industry-grade hardware. It estimates the amount of load to be shed based on the rate of frequency decline and distributes the load to be shed among the load buses based on the voltage dip at these buses. The UFLS in this study is implemented using a real-time digital simulator, phasor measurement units embedded in the relays, a global positioning system clock, and a synchrophasor vector processor. The load is modelled as a mixture of dynamic and static load. The implemented scheme restored the system frequency and voltage. The results emphasize its adaptability and suitability for implementation in industry. [ABSTRACT FROM AUTHOR]

AB  - The function and chronology of soapstone vessels in the Eastern Woodlands has been a contentious issue that deserves discussion at a more regional and subregional scale. We provide an overview of the Apple Barn site (40BT90) soapstone vessel assemblage, one of the largest Late Archaic/Early Woodland collections in the southern Appalachians. Results from residue analysis of pollen, starch, and phytoliths on four vessel fragments reveal the processing of various plants, correlating well with the macrobotanical results from the site. The AMS dates derived from seven sooted samples span ca. 1700 cal. B.C. to ca. 800 cal. B.C., suggesting mundane soapstone vessel use persists later in the southern Appalachians relative to other areas of the Southeast. When soapstone is no longer used at the Apple Barn site, post-750 cal. B.C., there is a significant shift in feature volume and organization, suggesting a change from seasonal group aggregations to semisedentary family tended garden plots. This shift denotes a significant change in foodways where the social and functional ties to soapstone were no longer relevant. [ABSTRACT FROM AUTHOR]

AB  - ABSTRACT Under a consent agreement among the Environmental Protection Agency (EPA) and proponents both for and against stricter regulation, EPA is to issue a new coal ash disposal rule by the end of 2014. Laboratory toxicity investigations often yield conservative estimates of toxicity because many standard test species are more sensitive than resident species, thus could provide information useful to the rule-making. However, few laboratory studies of coal ash toxicity are available; most studies reported in the literature are based solely on field investigations. This brief communication describes a broad range of toxicity studies conducted for the Tennessee Valley Authority (TVA) Kingston ash spill, results of which help provide additional perspective on the toxicity of coal ash.

AB  - ABSTRACT A baseline ecological risk assessment (BERA) was performed for residual ash in the Watts Bar Reservoir following a release of fly ash from the Tennessee Valley Authority (TVA) Kingston Fossil Plant. The site consists of parts of 3 rivers in eastern Tennessee comprising over 32 river kilometers. The purpose of the assessment was to determine if residual ash negatively impacts maintenance and reproduction of balanced communities or populations of potentially exposed ecological receptor groups in these rivers. This introductory article summarizes the site and environmental setting, assessment and measurement endpoints, risk characterization methods, and the study approach. Subsequent articles describe ecological risks to fish, benthic invertebrates, aquatic- and riparian-feeding wildlife, and aerial-feeding insectivores; and the role ecological risk characterization played in determining the most effective management of the residual ash, setting project remediation objectives and targets, and designing long-term monitoring to measure the effectiveness of the selected removal action.

AB  - ABSTRACT Benthic invertebrate communities were assessed after the December 2008 release of approximately 4.1 million m3 coal fly ash from a disposal dredge cell at the Tennessee Valley Authority (TVA) Kingston Fossil Plant on Watts Bar Reservoir in Roane County, Tennessee, USA. Released ash filled the adjacent embayments and the main channel of the Emory River, migrating into reaches of the Emory, Clinch, and Tennessee Rivers. Dredging was completed in summer 2010, and the benthic community sampling was conducted in December 2010. This study is part of a series that supported an Ecological Risk Assessment for the Kingston site. Benthic invertebrate communities were sampled at transects spread across approximately 20 miles of river that includes both riverine and reservoirlike conditions. Community composition was assessed on a grab sample and transect basis across multiple cross-channel transects to gain an understanding of the response of the benthic community to a fly ash release of this magnitude. This assessment used invertebrate community metrics, similarity analysis, geospatial statistics, and correlations with sediment chemistry and habitat. The community composition was reflective of a reservoir system, with dominant taxa being insect larva, bivalves, and aquatic worms. Most community metric results were similar for ash-impacted areas and upstream reference areas. Variation in the benthic community was correlated more with habitat than with sediment chemistry or residual ash. Other studies have reported that a benthic community can take several years to a decade to recover from ash or ash-related constituents. Although released ash undoubtedly had some initial impacts on the benthic community in this study, the severity of these effects appears to be limited to the initial smothering of the organisms followed by a rapid response and the initial start of recovery postdredging.

AB  - ABSTRACT The Tennessee Valley Authority conducted a Baseline Ecological Risk Assessment (BERA) for the Kingston Fossil Plant ash release site to evaluate potential effects of residual coal ash on biota in Watts Bar Reservoir, Tennessee. The BERA was in response to a release of 4.1 million m3 of coal ash on December 22, 2008. It used multiple lines of evidence to assess risks for 17 different ecological receptors to approximately 400 000 m3 of residual ash in the Emory and Clinch rivers. Here, we provide a brief overview of the BERA results and then focus on how the results were used to help shape risk management decisions. Those decisions included selecting monitored natural recovery for remediation of the residual ash in the Emory and Clinch rivers and designing a long-term monitoring plan that includes adaptive management principles for timely adjustment to changing conditions. This study demonstrates the importance of site-specific ecological data (e.g., tissue concentrations for food items, reproductive data, and population data) in complex ecological risk assessments. It also illustrates the value of the US Environmental Protection Agency's (USEPA) data quality objectives process in building consensus and identifying multiple uses of results. The relatively limited adverse effects of this likely worst-case scenario for ash-related exposures in a lotic environment provide important context for the USEPA's new coal combustion residue disposal rules.

AB  - ABSTRACT Extensive site-specific biological and environmental data were collected to support an evaluation of risks to the fish community in Watts Bar Reservoir from residual ash from the December 2008 Tennessee Valley Authority (TVA) Kingston ash release. This article describes the approach used and results of the risk assessment for the fish community, which consists of multiple measurement endpoints (measures of exposure and effects) for fish. The lines of evidence included 1) comparing postspill annual fish community assessments with nearby prespill data and data from other TVA reservoirs, 2) evaluating possible effects of exposures of fish eggs and larval fish to ash in controlled laboratory toxicity tests, 3) evaluating reproductive competence of field-exposed fish, 4) assessing individual fish health through physical examination, histopathology, and blood chemistry, 5) comparing fish tissue concentrations with literature-based critical body residues, and 6) comparing concentrations of ash-related contaminants in surface waters with US Environmental Protection Agency's (USEPA) Ambient Water Quality Standards for Fish and Aquatic Life. These measurement endpoints were treated as independent lines of evidence that were integrated into an overall weight-of-evidence estimate of risk to the fish community. Collectively, the data and analysis presented here indicate that ash and ash-related constituents pose negligible risks to the fish communities in Watts Bar Reservoir. This conclusion contradicts the predictions by some researchers immediately following the ash release of devastating effects on the aquatic ecology of Watts Bar Reservoir. The information presented in this article reaffirms the wisdom of carefully evaluating the evidence before predicting probable ecological effects of a major event such as the TVA Kingston ash release. This study demonstrates that a thorough and detailed investigation using multiple measurement endpoints is needed to properly evaluate ecological effects.

AB  - A study of a Powder River Basin (PRB) coal pile found that fugitive emissions from natural and human activity each produced similar levels of downwind fine + coarse (i.e., smaller than 10 µm, or PM10) particle mass concentrations. Natural impacts were statistically removed from downwind measurements to estimate emission factor Evfor bulldozers working on the pile. The Evdetermined here was similar in magnitude to emission factors (EFs) computed using a U.S. Environmental Protection Agency (EPA) formulation for unpaved surfaces at industrial sites, even though the latter was not based on data for coal piles. EF formulations from this study and those in the EPA guidance yield values of similar magnitude but differ in the variables used to compute Evvariations. EPA studies included effects of surface silt fraction and vehicle weight, while the present study captured the influence of coal moisture. Our data indicate that the relationship between PRB coal fugitive dust Ev(expressed as mass of PM10emitted per minute of bulldozer operation) and coal moisture content Mc(in percent) at the study site is best expressed as Ev=10f(Mc)where f(Mc) is a function of moisture. This function was determined by statistical regression between log10(Ev) and Mcwhere both Evand Mcare expressed as daily averages of observations based on 289 hours sampled during 44 days from late June through mid-November of 2012. A methodology is described that estimates Mcbased on available meteorological data (precipitation amount and solar radiation flux). An example is given of computed variations in daily Evfor an entire year. This illustrates the sensitivity of the daily average particulate EF to meteorological variability at one location. Finally, a method is suggested for combining the moisture-sensitive formulation for Evwith the EPA formulation to accommodate a larger number of independent variables that influence fugitive emissions. Implications: Fugitive coal dust emission factors (EFs) derived by this study contribute to the small existing knowledge base for a type of pollutant that will become increasingly important as ambient particulate standards become tighter. In areas that are not in attainment with standards, realistic EFs can be used for compliance modeling and can help identify which classes of sources are best targeted to achieve desired air quality levels. Reconciling emission factor formulations that are sensitive to different factors (i.e., those from the EPA and this study) produces a more powerful tool for estimating fugitive emissions at a broad range of sources.

AB  - In culvert-based navigation lock filling–emptying systems, inertia effects have a significant influence on the filling–emptying time and cause a (damped) oscillation of the water surface in the lock chamber around its equalization level, referred to as the overtravel phenomenon. In this paper, the derivation of analytical formulae for the lock filling–emptying time and overtravel peak of systems consisting of a number of identical culverts is revisited. In comparison to earlier publications, the underlying assumptions are made explicit and the importance of accounting for the surface area ratio of lock chamber to upper reservoir in case of filling (or lower reservoir in case of emptying) is pointed out. Additionally, it is shown how the applicability of the analytical formulae can be extended to lock filling–emptying systems with more complex lay-outs by using an “equivalent culvert” approach. The validity of the analytical formulae is thoroughly assessed, first by comparing to an accurate numerical solution of the governing non-linear second-order differential equations, and second, by means of experiments in a physical model.

AB  - A suite of offline and real-time gas- and particle-phase measurements was deployed at Look Rock, Tennessee (TN), during the 2013 Southern Oxidant and Aerosol Study (SOAS) to examine the effects of anthropogenic emissions on isoprene-derived secondary organic aerosol (SOA) formation. High- and low-time resolution PM2.5 samples were collected for analysis of known tracer compounds in isoprene-derived SOA by gas chromatography/electron ionization-mass spectrometry (GC/EI-MS) and ultra performance liquid chromatography/diode array detection-electrospray ionization-high-resolution quadrupole time-of-flight mass spectrometry (UPLC/DAD-ESI-HR-QTOFMS). Source apportionment of the organic aerosol (OA) was determined by positive matrix factorization (PMF) analysis of mass spectrometric data acquired on an Aerodyne Aerosol Chemical Speciation Monitor (ACSM). Campaign average mass concentrations of the sum of quantified isoprene-derived SOA tracers contributed to ~9% (up to 26%) of the total OA mass, with isoprene-epoxydiol (IEPOX) chemistry accounting for ~97% of the quantified tracers. PMF analysis resolved a factor with a profile similar to the IEPOX-OA factor resolved in an Atlanta study and was therefore designated IEPOX-OA. This factor was strongly correlated (r²>0.7) with 2-methyltetrols, C5-alkene triols, IEPOX-derived organosulfates, and dimers of organosulfates, confirming the role of IEPOX chemistry as the source. On average, IEPOX-derived SOA tracer mass was ~25% (up to 47%) of the IEPOX-OA factor mass, which accounted for 32% of the total OA. A low-volatility oxygenated organic aerosol (LV-OOA) and an oxidized factor with a profile similar to 91Fac observed in areas where emissions are biogenic-dominated were also resolved by PMF analysis, whereas no primary organic aerosol (POA) sources could be resolved. These findings were consistent with low levels of primary pollutants, such as nitric oxide (NO~0.03ppb), carbon monoxide (CO~116 ppb), and black carbon (BC~0.2 µg m-3). Particle-phase sulfate is fairly correlated (r²~0.3) with both MAE- and IEPOX-derived SOA tracers, and more strongly correlated (r²~0.6) with the IEPOX-OA factor, in sum suggesting an important role of sulfate in isoprene SOA formation. Moderate correlation between the methacrylic acid epoxide (MAE)-derived SOA tracer 2-methylglyceric acid with sum of reactive and reservoir nitrogen oxides (NOy; r²=0.38) and nitrate (r²=0.45) indicates the potential influence of anthropogenic emissions through long-range transport. Despite the lack of a~clear association of IEPOX-OA with locally estimated aerosol acidity and liquid water content (LWC), box model calculations of IEPOX uptake using the simple GAMMA model, accounting for the role of acidity and aerosol water, predicted the abundance of the IEPOX-derived SOA tracers 2-methyltetrols and the corresponding sulfates with good accuracy (r²~0.5 and ~0.7, respectively). The modeling and data combined suggest an anthropogenic influence on isoprene-derived SOA formation through acid-catalyzed heterogeneous chemistry of IEPOX in the southeastern US. However, it appears that this process was not limited by aerosol acidity or LWC at Look Rock during SOAS. Future studies should further explore the extent to which acidity and LWC becomes a limiting factor of IEPOX-derived SOA, and their modulation by anthropogenic emissions. [ABSTRACT FROM AUTHOR]

AB  - Air quality measurements at Look Rock, Tennessee - on the western edge of the Great Smoky Mountains National Park - were begun in 1980 and expanded during the 1980s to a National Park Service (NPS) IMPROVE network station. Measurements were expanded again by the Tennessee Valley Authority (TVA, 1999-2007) to examine the effects of electric generating unit (EGU) emission reductions of SO2 and NOx on air quality at the station. Analysis of temporal trends (1999-2013) has been conducted at the site in collaboration with activities related to the 2013 Southeast Atmosphere Study (SAS) at Look Rock and other southeastern US locations. Key findings from these trend studies include the observation that primary pollutant levels have consistently tracked emissions reductions from EGUs and other primary sources in the region but reductions in secondary pollutants such as particulate sulfate and, specifically, ozone have been smaller compared to reductions in primary emissions. Organic carbonaceous material (OM) remains a major contributor (30-40% in the period 2009-2013) to fine particulate mass at the site, as confirmed by ACSM measurements at the site in 2013. A large portion (65-85%) of carbon in OM derives from modern carbon sources based on 14C measurements. Important parameters affecting ozone levels, fine mass and visibility also include the specific diurnal meteorology at this ridge-top site, its location in a predominantly mixed-deciduous forest, and the presence of primary sources of precursors at distances of 50-500 km from the site in all directions.

AB  - During the past 100 years, most large rivers in North America have been altered for flood control, hydropower, navigation or water supply development. Although these activities clearly provide important human services, their associated environmental disturbances can profoundly affect stream-dwelling organisms. We used dynamic multi-species occupancy models combined with a trait-based approach to estimate the influence of site-level and species-level characteristics on patch dynamic rates for 15 darter species native to the Elk River, a large, flow-regulated Tennessee River tributary in Tennessee and Alabama. Dynamic occupancy modelling results indicated that for every 2.5 °C increase in stream temperature, darters were 3.94 times more likely to colonize previously unoccupied stream reaches. Additionally, large-bodied darter species were 3.72 times more likely to colonize stream reaches compared with small-bodied species, but crevice-spawning darter species were 5.24 times less likely to colonize previously unoccupied stream reaches. In contrast, darters were 2.21 times less likely to become locally extinct for every 2.5 °C increase in stream temperature, but high stream discharge conditions elevated the risk of local extinction. Lastly, the presence of populations in neighbouring upstream study reaches contributed to a lower risk of extinction, whereas the presence of populations in neighbouring downstream study reaches contributed to higher rates of colonization. Our study demonstrates the application of a trait-based approach combined with a metapopulation framework to assess the patch dynamics of darters in a regulated river. Results from our study will provide a baseline for evaluating the ecological consequences of alternative dam operations. Copyright © 2014 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

AB  - Nighttime concentrations of the gas phase nitrate radical (NO 3 ) were successfully measured during a four week field campaign in an arid urban location, Reno Nevada, using long-path Differential Optical Absorbance Spectrometry (DOAS). While typical concentrations of NO 3 ranged from 5 to 20 ppt, elevated concentrations were observed during a wildfire event. Horizontal mixing in the free troposphere was considerable because the sampling site was above the stable nocturnal boundary layer every night and this justified a box modeling approach. Process analysis of box model simulations showed NO 3 accounted for approximately half of the loss of internal olefins, 60% of the isoprene loss, and 85% of the α-pinene loss during the nighttime hours during a typical night of the field study. The NO 3 + aldehyde reactions were not as important as anticipated. On a polluted night impacted by wildfires upwind of the sampling location, NO 3 reactions were more important. Model simulations overpredicted NO 2 concentrations for both case studies and inorganic chemistry was the biggest influence on NO 3 concentrations and on nitric acid formation. The overprediction may be due to additional NO 2 loss processes that were not included in the box model, as deposition and N 2 O 5 uptake had no significant effect on NO 2 levels.

AB  - Unregulated river systems are organized in a hierarchy in which large-scale factors (i.e., landscape and segment scales) influence local habitats (i.e., reach, meso-, and microhabitat scales), and both differentially exert selective pressures on biota. Dams, however, create discontinua in these processes and change the hierarchical structure. We examined the relative roles of hydrology and other instream factors, within a hierarchical landscape context, in organizing fish communities in regulated and unregulated tributaries to the Upper Tennessee River, USA. We used multivariate regression trees to identify factors that partition fish assemblages based on trait similarities, irrespective of spatial scale. We then used classical path analysis and structural equation modeling to evaluate the most plausible hierarchical causal structure of specific trait-based community components, given the data. Both statistical approaches suggested that river regulation affects stream fishes through a variety of reach-scale variables, not always through hydrology itself. Although we observed different changes in flow, temperature, and biotic responses according to regulation types, the most predominant path in which dam regulation affected biota was via temperature alterations. Diversion dams had the strongest effects on fish assemblages. Diversion dams reduced flow magnitudes, leading to declines in fish richness but increased temperatures, leading to lower abundances in equilibrium species and nest guarders. Peaking and run-of-river dams increased flow variability, leading to lower abundances in nest-guarding fishes. Flow displayed direct relationships with biotic responses; however, results indicated that changes in temperature and substrate had equal, if not stronger, effects on fish assemblage composition. The strength and nature of relationships depended on whether flow metrics were standardized for river size. We suggest that restoration efforts in regulated rivers focus on improving flow conditions in conjunction with temperature and substrate restoration. (English) [ABSTRACT FROM AUTHOR]
AB  - Les réseaux fluviaux non régularisés sont organisés selon une hiérarchie dans laquelle des facteurs à grande échelle (c.-à-d. à l'échelle du paysage et du segment) influencent les habitats locaux (c.-à-d. à l'échelle du tronçon et des méso- et microhabitats), ces deux types de facteurs exerçant des pressions de sélection différentes sur le biote. Les barrages créent toutefois des discontinuités dans ces processus et modifient la structure hiérarchique. Nous avons examiné les rôles relatifs de l'hydrologie et d'autres facteurs du cours d'eau, dans un contexte de paysage hiérarchique, dans l'organisation des communautés de poissons dans des affluents régularisés et non régularisés de la rivière Upper Tennessee (États-Unis). Nous avons utilisé des arbres de régression multivariée pour cerner les facteurs qui divisent les assemblages de poissons selon des similitudes de caractères, quelle que soit l'échelle spatiale. Nous avons ensuite utilisé l'analyse de dépendance classique et la modélisation d'équations structurales pour évaluer la structure causale hiérarchique la plus plausible de composantes de la communauté basées sur des caractères précis, étant donné les données. Les deux approches statistiques indiqueraient que la régularisation des rivières influence les poissons des cours d'eau par l'entremise de diverses variables à l'échelle du tronçon, mais pas toujours par l'entremise de l'hydrologie comme telle. Bien que nous ayons observé différentes modifications du débit, de la température et des réactions biotiques selon le type de régularisation, la voie causale dominante par laquelle la régularisation par un barrage influençait le biote est la modification des températures. Les barrages de dérivation exerçaient les effets les plus forts sur les assemblages de poissons, en réduisant la magnitude des débits, menant du coup à la diminution de la richesse des poissons, mais ils causaient une augmentation des températures, entraînant une diminution de l'abondance chez les espèces en équilibre et les gardeurs des nids. Les barrages de pointe et au fil de l'eau accroissaient la variabilité des débits, menant à de plus faibles abondances des poissons gardeurs de nid. Si le débit présentait des relations directes avec les réactions biotiques, les résultats indiquent toutefois que les modifications de la température et du substrat avaient des effets égaux, voire plus grands sur la composition des assemblages de poissons. La force et la nature des relations dépendent de la normalisation ou non des paramètres d'écoulement en fonction de la taille de la rivière. Nous suggérons que les efforts de restauration dans les rivières régularisées devraient s'axer sur l'amélioration des conditions d'écoulement, combinée au rétablissement de la température et à la restauration du substrat.

AB  - A dike failure at the Tennessee Valley Authority Kingston Fossil Plant in East Tennessee, United States, in December 2008, released approximately 4.1 million m3 of coal ash into the Emory River. From 2009 through 2012, samples of mayfly nymphs ( Hexagenia bilineata) were collected each spring from sites in the Emory, Clinch, and Tennessee Rivers upstream and downstream of the spill. Samples were analyzed for 17 metals. Concentrations of metals were generally highest the first 2 miles downstream of the spill, and then decreased with increasing distance from the spill. Arsenic, B, Ba, Be, Mo, Sb, Se, Sr, and V appeared to have strong ash signatures, whereas Co, Cr, Cu, Ni, and Pb appeared to be associated with ash and other sources. However, the concentrations for most of these contaminants were modest and are unlikely to cause widespread negative ecological effects. Trends in Hg, Cd, and Zn suggested little (Hg) or no (Cd, Zn) association with ash. Temporal trends suggested that concentrations of ash-related contaminants began to subside after 2010, but because of the limited time period of that analysis (4 yr), further monitoring is needed to verify this trend. The present study provides important information on the magnitude of contaminant exposure to aquatic receptors from a major coal ash spill, as well as spatial and temporal trends for transport of the associated contaminants in a large open watershed.

T1  - Influence of Aridity and Weather on Breeding-Season Survival of Northern Bobwhites in South Texas, USA.

AB  - Understanding vital rates of wildlife populations is essential for developing realistic management objectives. We conducted an analysis of data from four northern bobwhite Colinus virginianus research projects conducted in South Texas to examine the extent that environmental factors (total seasonal precipitation, mean maximum seasonal temperature, growing-season length, and Keetch-Byram drought index values) influenced survival during the 5-mo (April-August) breeding season. We constructed generalized logistic mixed models and compared them using Akaike's Information Coefficient to rank their parsimony. Our selected model (cumulative breeding-season survival = bobwhite sex + growing season length [days of photosynthetic activity] + Keetch-Byram Drought Index score [averaged from April to August] + site-specific effects of each ranch) explained 35.3% of the total variation in the data set. Breeding season survival was positively related to growing season length (β = 0.01, 95% CI = 0.00-0.02), and negatively related to Keetch-Byram Drought Index score (β = −0.01, 95% CI = −0.01 to −0.01; rounded to two digits). Managers cannot control weather, but the ability to account for nearly one-third of variation in breeding season survival from weather, sex, and site-specific effects of the ranch refines our understanding of factors that influence bobwhite population dynamics in South Texas.

AB  - The world entered the Nuclear Age - as some would call it, "Day One" - on July 16, 1945, at the Trinity site in New Mexico. As author Dan Zak recounts in Almighty, the selection of the site's code name was made by the Manhattan Project's lead physicist, J. Robert Oppenheimer, "because he had both John Donne and the Bhagavad Gita on the brain": in the one case, the Father, Son and Holy Ghost, and in the other, creator, preserver and destroyer. Oppenheimer later said that as he watched the first atomic fireball and mushroom cloud soar, he recalled these words from the Bhagavad Gita: "Now I am become Death, the destroyer of worlds." Thus, from the outset of the atomic era, seeds of spirituality and doubts as to what nuclear weapons would present for humankind's fate seemed almost inextricably and equally interwoven with military and scientific concerns.
