This characterization procedure has been validated by comparing the measured M(n)BAR of several different polymers and polymer mixtures with expected values. The M(n)BAR of these samples ranged from 1000 to 1,000,000. The major advantage of this method is that it is not necessary either to utilize the Mark-Houwink constants or to determine the weight fraction of the eluting sample with a concentration detector. A convenient means is thus provided to determine the true M(n)BAR of copolymers, polymer mixtures, and samples of unknown structure.

NMR imaging offers special advantages for following chemical changes, even though techniques for imaging solids are still under rapid development. Herein, we report the application of a recently developed NMR pulse sequence that enables the efficient observation of organic solids in spite of the large proton dipolar coupling in the solid. The reactions of substituted benzoic acid crystals and powders with ammonia gas have been monitored. The reactions are inherently (crystal) or by design (powder) spatially anisotropic.

Much of its development has been expressed in probabilistic language, although image enhancement has been somewhat more physical or geometric in description. Here phasing and entropy maximization are embedded in the quantum mechanical problem of reconstructing an electronic one-matrix under experimental constraints. Entropy on an N-representable one-particle density matrix is well defined. The entropy is the expected form, and it is a simple function of the one-matrix eigenvalues which all must be non-negative. Certain other properties are pertinent to phasing which is implicit in one-matrix reconstruction governed by entropy maximization. Throughout this work reference is made to informational entropy, not the entropy of thermodynamics. C1 GEOCENTERS INC, FT WASHINGTON, MD 20744 USA.

In the case of polyimides, the effects of test temperature, thermal history, strain rate, type of filler, and filler volume fraction on structure-property relations will be discussed. For BMIs we report systematic Fourier transform infrared spectroscopy and differential scanning calorimetry studies of the cure reactions as a function of chemical composition and time-temperature cure conditions and then describe the resultant cross-linked network structure based on our understanding of the cure reactions. The optimization of the BMI matrix toughness will be considered in terms of network structure and process-induced matrix microcracking. We also describe optimization of composite prepreg, lamination and postcure conditions based on cure kinetics, and their relationship to the BMI viscosity-time-temperature profiles. The critical processing-performance limitations of high-temperature polymer matrices will be critically discussed, and toughening approaches to address these limitations, such as toughness over a wide temperature range, will be presented.

Input parameters include volumetric flow rates of exhaust and makeup air, solvent threshold limit values and evaporation rates, and a set of exchange coefficients that characterize air circulation inside the vessel. This technique enables engineers to rate quantitatively the anticipated health risks of applying a combination of coatings. The technique also provides engineering managers a predictive tool to organize work schedules so that health and safety can become input parameters to an engineering enterprise.

The methods of collecting, transporting, cultivating, and identifying aerobic bacteria in bone and joint infections have improved markedly since the early 1980s. In addition, many of the anaerobes have been reclassified and renamed. The purpose of this study was to provide more current information regarding the incidence of recovery of anaerobic bacteria from clinical specimens of infected bone and joint. MATERIALS AND METHODS: Specimens from 73 infected bone specimens and 65 infected joints inoculated on media supportive for aerobic and anaerobic bacteria showed bacterial growth. RESULTS: One hundred fifty-seven organisms (2.2 isolates/specimen), consisting of 122 anaerobic bacteria (1.7 isolates/specimen) and 35 facultative or aerobic bacteria (0.5 isolate/specimen), were recovered from the 73 bone specimens. Anaerobic bacteria were recovered with aerobe or facultative bacteria in 24 (33%) instances. The predominant anaerobes were Bacteroides species (49 isolates), anaerobic cocci (45), Fusobacterium species (11), Propionibacterium acnes (7), and Clostridium species (6). Conditions predisposing to bone infections were vascular disease, bites, contiguous infection, peripheral neuropathy, hematogenous spread, and trauma. Pigmented Prevotella and Porphyromonas species were mostly isolated in skull and bite infections (7 of 19), members of the Bacteroides fragtilis group in hand and feet infection (12 of 16), and Fusobacterium species in skull, bite, and hematogenous long bone infections. Seventy-four organisms (1.1 isolates/specimen), consisting of 67 anaerobic bacteria (1.0 isolate/specimen) and 7 facultative or aerobic bacteria (0.1 isolate/specimen), were isolated from 65 joint specimens. The predominant anaerobes were P. acnes (24 isolates), anaerobic cocci (17), Bacteroides species (10), and Clostridium species (5). Predisposing conditions to joint infection were trauma, prior surgery, presence of a prosthetic joint, and contiguous infection. P. acnes isolates were associated with prosthetic joints, members of the B. fragilis group with hematogenous spread, and Clostridium species with trauma. The clinical presentation of these cases is discussed. CONCLUSION: These data highlight the importance of anaerobic bacteria in bone and joint infection.

The etiology was Neisseria meningitidis (mostly group A) in 27.3% of the patients, Mycobacterium tuberculosis in 19.7%, Streptococcus pneumoniae in 7.3%, and Haemophilus influenzae in 4. 1%. Almost 27% of the cases had purulent meningitis but without detectable etiology; however, the epidemiologic data suggest that most of these had meningococcal meningitis. Encephalitis was suspected in 12.5% of the patients, Most of the meningococcal, pneumococcal, and Haemophilus cases occurred during the winter months. The number of meningococcal and culture-negative purulent cases per year reached a maximum three times during the 22.5 years of this study. There were more males than females in all etiologic groups, with the ratio for the total patient population being 1.6:1. The average age ranged between 11.7 and 16.5 years for all groups except for Haemophilus patients, who had a mean age of 2.5 years. The mortality rate was almost 55% for tuberculous patients and was approximately 40% for both pneumococcal and Haemophilus patients; it was 8.5% in patients with meningococcal disease.

CASE SUMMARY: A 31-year-old woman who had been on long-term warfarin therapy for atrial fibrillation was admitted to the hospital with hemoptysis. Following reversal of her anticoagulation, she had a tonic-clonic seizure nine days after admission. An emergency computed tomography scan revealed cerebral edema, which was initially treated with hyperventilation and steroids. Two days later, a repeat scan showed progression of the cerebral edema with midline shift. Mannitol 550 g was infused over the next 28 hours, precipitating ARF. Despite prompt hemodialysis to reverse the renal failure, the patient died. This case of apparent mannitol-induced ARF illustrates several pathophysiologic effects of this agent. DISCUSSION: Case reports in the literature discussing mannitol-induced ARF are reviewed and compared. A relationship between dose and ARF and its reversal with hemodialysis is postulated. CONCLUSIONS: It is likely that sufficient doses of mannitol may lead to ARF. Limitation of dose may prevent and treatment with hemodialysis may reverse ARF in these instances.

Waves generated at one end of a 116-meter wave tank are observed for breaking at a section of the tank approximately 30 meters from the wavemaker and in regions spanning three and six meters about the section. Emphasis is on the relative number of breaking waves observed at the section and in the regions about it, and on the relative number of crest amplitudes exceeding specified levels at the section. Measurements at the section are shown to be in good agreement with predictions formed using idealized assumptions about the breaking waves and a modified Rayleigh distribution of crest amplitudes that accounts approximately for nonlinear effects in seas with narrow-banded wave frequencies. Results indicate that the average downward crest acceleration of breaking waves in these sea states is equal approximately to one-third the acceleration of gravity. Experimental measurements of breaking in regions about the section are shown to be in good agreement with theoretical predictions relating breaking events over a region to those at a fixed location.

Because of their contactless nature, they can also serve as in-situ, as well as ex-situ diagnostics of processing effects during various stages of optoelectronic device formation. In this paper, we will focus on the applications of photoreflectance to study the effects of various processing procedures such as dry etching, surface passivation and metallization on the electrical properties of GaAs. We will show how certain information, such as barrier heights and densities of surface states can be obtained in a contactless fashion. C1 NATL INST STAND & TECHNOL,GAITHERSBURG,MD 20899.

RADIO OBSERVATIONS SO ASTRONOMICAL JOURNAL LA English DT Article ID STAR FORMATION; CONTINUUM EMISSION; SPIRAL GALAXIES AB As the second part of an ongoing investigation into the triggering of nuclear radio emission in interacting galaxies, we present the results of a Very Large Array snapshot survey of southern interacting galaxies at 6 and 20 cm. The purpose of the survey was to search for and classify the nature of radio emission in a set of advanced-interaction disk galaxies which we had previously imaged optically. There were 42 interacting systems in our sample as well as 10 control systems, none of which had been previously detected by the Parkes surveys. Maps of the radio emission are presented and discussed. The radio properties of the galaxies are compared with their optical and infrared properties to determine the nature of the radio emission. We find that the radio emission in all our interacting galaxies can be attributed to processes associated with a burst of star formation caused by the galaxy interaction. In a specific case (0558-33), we quantitatively confirm earlier models of a starburst, but using radio observations to estimate the number of supernova remnants rather than optical spectra and broadband observations. In no case did we find clear evidence for a buried active nucleus. Further high resolution observations are needed however to better assess the contribution from any compact, weak active nuclei. Despite the obvious interaction these galaxies have undergone, none have developed into powerful radio sources, even though many of the most powerful radio sources are themselves the likely products of galaxy-galaxy interactions. We briefly discuss the implications for the triggering of nuclear activity. C1 USN,RES LAB,CTR ADV SPACE SENSING,WASHINGTON,DC 20375.

Using these data and photometric data from the literature we have modeled and subtracted the foreground dust contribution in the color excess E(B-V) and the visual polarization. The resulting intracluster dust component is found to have a polarization efficiency less than the maximum observed for the interstellar medium. The intracluster dust is also characterized by a ratio of E(V-K)/E(B-V) to lambda(max) higher than the canonical value for the interstellar medium.

For all these sources, the standard spherically symmetric expanding shell model fails to fit the water maser data as well as it fits 1612 MHz OH maser data. A component of radial outflow appears to be present in the H2O shells of three stars (RT Vir, IK Tau, VX Sgr). This and the comparable velocity ranges of H2O and OH masers for each star indicate that at least some parcels of gas are accelerated nearly to the terminal outflow velocity at or inside the radius of the H2O shell. The maser distributions generally are quite asymmetric relative to the estimated stellar positions. The absolute positions of the water masers toward these stars have been determined with a rms accuracy of about 0.1'' and the estimated stellar positions agree with astrometric optical positions at this level of accuracy. For IK Tau and W Hya, the maps of H2O maser features have been compared with other observations of similar angular and spectral resolution at similar phases of their light curves. These are the first such detailed comparisons of water maser maps for circumstellar envelopes. In the case of IK Tau, the agreement of positions and velocities in the maps obtained from these data and data taken a year earlier is quite good. On the other hand, although the similarity of the spectra is striking, maps of water masers for W Hya presented here show little correspondence with data taken five years later, indicating that significant changes in the angular distributions of H2O Masers Can occur over time scales larger than a few years.

Spectra have been obtained from 215 solar flares and 177 gamma-ray bursts. Although lines are common in flares, no narrow or moderately broadened lines were observed in any of the bursts. The rate of bursts is consistent with a constant over the mission but is weakly correlated with solar activity (approximately 95% confidence level). No evidence was found for bursts of 511 keV line emission, unaccompanied by a strong continuum, at levels greater-than-or-equal-to 5 X 10(-2) gamma cm-2 s-1 for bursts lasting less-than-or-equal-to 16 s. No evidence was found for broad features near 1 MeV from Cyg X-1, the Galactic Center, or the Crab in 12-day integrations at levels greater-than-or-equal-to 6 x 10(-3) gamma cm-2 s-1.

The position agrees with previous HCN results. This clump is about 0.8'' west of the center of the group of H2O masers; the virial mass is 18 M.. From the virial mass and estimated radius, 0.006 pc, the average density is 4 x 10(8) cm-3. From the peak H-2 column density, 10(25) Cm-2, and the NH3 column density, 10(17) cm(-2), the NH3/H2 ratio is 10(-8). As found previously, there is prominent absorption toward the high surface brightness, compact H II region W3(OH). However, toward W3(OH), there is no emission counterpart to the NH3 absorption. There are weak, extended emission features more than 15'' SE and SW of W3(OH). This emission is not found to the north of W3(OH). This asymmetrically distributed emission would seem to provide an argument against a toroidal belt of molecular gas surrounding W3(OH). The largest scale feature is a remarkable, 1.5' long, less than 20'' wide filament which extends from N of the H II region-H2O maser complex to the NE. Within this filament there are at least five maxima. The T(k) in this region is of order 20-30 K, and the FWHP line width is less than 2.4 km s-1. From virial estimates, the molecular mass In our map is less than 200 M.. C1 USN,RES LAB,CTR ADV SPACE SENSING,WASHINGTON,DC 20375.

The binaries selected for this study are very likely physical pairs. Dating of the B-type stars with respect to the zero-age main sequence, as well as spectroscopic observations of the late-type stars, provides evidence for the extreme youth of these systems with ages typically near or below 10(8) yr. Surprisingly, the late-B component was in many cases detected as an X-ray source, in contrast to previous findings that X-ray emission among late-B field stars is rather uncommon.

It is very common, however, in practice that we only monitor subjects periodically and, therefore, we know only whether responses occur or not during an interval. This paper includes a quantitative discussion of the effect resulting from data grouping or interval censoring on the required sample size when we have two treatment groups. Furthermore, with the goal of exploring the optimum in the number of subjects, the number of examinations per subject for test responses, and the total length of a study time period, this paper also provides a general guideline about how to determine these to minimize the total cost of a study for a desired power at a given alpha-level. A specified linear cost function that incorporates the costs of obtaining subjects, periodic examinations for test responses of subjects, and the total length of a study period, is assumed, primarily for illustrative purpose.

We compare channel conductance in the presence of nonpenetrating water-soluble polymers with that obtained for polymer-free electrolyte solution. The contribution of the access resistance to the total alamethicin channel resistance is approximately 10% for first three open channel levels. The open alamethicin channel radii inferred for these first three levels from the access resistance are 6.3, 10.3, and 11.4 angstrom. The dependence of channel conductance on polymer molecular weight also allows evaluation of the channel dimensions from polymer exclusion. Despite varying conductance, it was shown that steric radii of the alamethicin channel at different conductance levels remain approximately unchanged. These results support a model of the alamethicin channel as an array of closely packed parallel pores of nearly uniform diameter. C1 OFF NAVAL RES,800 N QUINCY ST,ARLINGTON,VA 22217.

The initial fibers tested exhibited poor sensitivity, primarily due to loss of fluorescent signal which was collected by the sensing region but which failed to propagate back in the clad fiber due to V-number mismatch. Earlier work has shown that tapering of the sensing region improves coupling of the fluorescence signal. While sensitivity was increased, there was a lack of reproducibility of signal magnitude from fiber to fiber. To produce a more consistent fiber probe which maintained sensitivity, signal return along the length of the probe was investigated. An effective design, termed a combination taper, was found which provided an even signal return along the fiber's length. The fiber tapers down to the V-number matching radius over 1 cm, maintaining total internal reflection, then continues to taper gently along the following 9 cm to near the distal end. The combination taper fiber provides not only the desired sensitivity, but also improved reproducibility. C1 USN,RES LAB,CTR BIOMOLEC SCI & ENGN,CODE 6900,WASHINGTON,DC 20375.

Cooperative interactions among cytoskeletal protein subunit conformational states have been used to model signal transmission and information processing. In the present work we present a theoretical model for molecular computing in which Boolean logic is implemented in parallel networks of individual MTs interconnected by MAPs. Conformational signals propagate on MTs as in data buses and in the model MAPs are considered as Boolean operators, either as bit-lines (like MTs) where a signal can be transported unchanged between MTs ('BUS-MAP'), or as bit-lines where a Boolean operation is performed in one of the two MAP-MT attachments ('LOGIC-MAP'). Three logic MAPs have been defined ('NOT-MAP', 'AND-MAP', 'XOR-MAP') and used to demonstrate addition, subtraction and other arithmetic operations. Although our choice of Boolean logic is arbitrary, the simulations demonstrate symbolic manipulation in a connectionist system and suggest that MT-MAP networks can perform computation in living cells and are candidates for future molecular computing devices.

Patients with extensive-stage SCLC and hyponatremia had shorter survival than patients with extensive stage SCLC and normal serum sodium values (P = 0.012). Of the 11 hyponatremic patients with SCLC and tumor cell lines available for study, 9 produced ANF mRNA, 7 of 11 produced AVP mRNA, and 5 of 11 produced both ANF mRNA and AVP mRNA. All 11 cell lines produced either ANF mRNA and ANF peptide or AVP mRNA and AVP peptide, or both. The quantity of AVP peptide in the tumor cell lines was more closely associated with hyponatremia in the patients (P = 0.0026, r2 = 0.28) than was the production of ANF peptide (P = 0.066, r2 = 0.12), although neither association was strong. All tumor cell lines studied from SCLC patients with hyponatremia produce ANF and/or AVP mRNA and peptides. C1 USN,NATL MED CTR,NCI,MED ONCOL BRANCH,BLDG 8,RM 5105,BETHESDA,MD 20889.

Both resins are easily processed into shaped and void-free components. The polymers and corresponding pyrolysates exhibit outstanding thermal properties. As the heat treatment is progressively increased, a carbonaceous mass is produced yielding a high char yield. As the pyrolysis temperature was raised to 700-degrees-C, the density increased and remained at a fairly constant value to 1200-degrees-C. Further heat treatment to 2700-degrees-C resulted in a reduction in the density. Shrinkage appears to occur at about the same rate as free volume is being produced within the developing pyrolysates causing collapse to essentially microporous systems.

Following a subpicosecond rise, each frequency-specific trace in ethylene glycol exhibits either a slower increase or a slower decrease in transmission; an additional long-term decay is seen in methanol solution. The data are generally consistent with recent solvation dynamics studies that employed different probe molecules, but the solvation time we measure for ethylene glycol is an order of magnitude shorter than previously reported.

Enhancement of adrenergic action has been implicated as a physiological path by which naloxone effects changes in cardiac function during endotoxin shock, but the mechanism for changes in various splanchnic vascular beds has not been examined. In this study, we examined the role of beta-adrenergic actions in cardiovascular performance and the splanchnic perfusion changes caused by naloxone during endotoxin shock. Rats were instrumented with catheters in the tail artery, left cardiac ventricle, and jugular vein. Twenty-four hours later, rats received saline or endotoxin (2 mg/kg) challenge intravenously over 30 min, followed at 40 min by iv naloxone (or saline) treatment (4 mg/kg + 2 mg/kg . hr) in the presence or absence of propranolol (1 mg/kg + 1 mg/kg . hr). Radiolabelled microspheres were used to determine cardiac outputs and blood flows at 0, 30, 60, and 120 min after beginning endotoxin infusion. Blood pressure was not affected by endotoxin challenge, but cardiac output and most organ blood flows fell over time. Beta-adrenergic blockade did not alter this response. Naloxone improved cardiac output and blood flow to the stomach, small intestine, colon, and spleen but not to other splanchnic organs. Naloxone also increased renal and coronary blood flows. The improvements in cardiac output with naloxone were ablated in the presence of propranolol, as were the increases in gastric, colonic, splenic, coronary, and renal blood flows. However, the beneficial effect of naloxone on small bowel blood flow was not diminished by blockage of beta receptors. These results suggest that the effects of opioid antagonism are mediated, in part, by enhancing endogenous beta-adrenergic actions in vivo. Improvements in the splanchnic circulation are selectively altered by naloxone during endotoxin shock, some independent of beta-adrenergic actions. Understanding this phenomenon can lead to the appropriate use of opioid antagonism, should it prove clinically useful in the treatment of septic shock.

Levels of methylmethacrylate monomer in systemic blood were measured at intervals after insertion of the prosthesis. Levels of methylmethacrylate monomer in shed blood were measured at intervals after insertion of the drain. Levels of fat in systemic blood were measured preoperatively and 30 minutes after insertion of the prosthesis. Levels of fat in shed blood were measured 60 minutes after insertion of the drain. No significant fat or methylmethacrylate monomer was noted in systemic blood. Levels of methylmethacrylate monomer in shed blood were highest five minutes after insertion of the drain. Levels of methylmethacrylate monomer in shed blood collected from the hip were significantly lower than levels in shed blood from the knee. Levels of shed blood from the hip and knee were undetectable six hours after insertion of the drain. Shed blood from the hips and knees contained fat particles of three diameters: fat particles less than 9 mum, 9-40 mum, and greater than 40 mum. The diameter of most of the fat particles in the shed blood was less than 9 mum. Fat particles less than 40 mum in diameter will not be removed by microaggregate screen filters 40 mum in diameter.

They define the notion of a good split, and first prove that G has a unique minimal decomposition into graphs, none of which has a good split, and second prove that the graphs that do not have a good split are precisely 3-connected graphs, bonds and polygons. This paper provides an analogue of the first result above for 3-connected graphs, and an analogue of the second for minimally 3-connected graphs. Following the basic strategy of Cunningham and Edmonds, an appropriate notion of good split is defined. The first main result is that if G is a 3-connected graph, then G has a unique minimal decomposition into graphs, none of which has a good split. The second main result is that the minimally 3-connected graphs that do not have a good split are precisely cyclically 4-connected graphs, twirls (K3,n for some n greater-than-or-equal-to 3) and wheels. From this it is shown that if G is a minimally 3-connected graph, then G has a unique minimal decomposition into graphs, each of which is either cyclically 4-connected, a twirl or a wheel.

The theoretical model includes the elliptic type of momentum, energy and species equations with a second-order single-step chemical reaction model of the Arrhenius type. The discrete ordinates method is employed to solve the radiative transfer equation. Numerical calculations are performed for a wide range of mass absorption coefficients and wall emissivities to characterize the flame behavior. When the gas radiation is stronger, the radiative heat loss causes the flame to retreat downstream, causes shrinkage of the flame size, and causes a decrease in the maximum flame temperature. The flame configuration is thus strongly affected by the gas radiation process. C1 KOREA ADV INST SCI & TECHNOL,DEPT AEROSP ENGN,SEOUL 131,SOUTH KOREA.

Self-excited combustion oscillations occur when the flame interacts with the large-scale vortices which are excited in the shear layer by the acoustic forcing at the duct resonance modes. The periodic heat release produced by the combustion inside the vortices further excite the duct acoustics. The fuel to air mixture ratio is shown to have an important effect on the interaction between the flame and vortices. The effect on the flame structure of pressure and CH control systems is described. The transition from controlled conditions to uncontrolled and vice versa is visualized. The roll-up of coherent structures dominating the flame in the self-excited conditions is disrupted by the controller; the shear layer is forced at the exact phase necessary to cancel the perturbation due to the duct acoustic pressure. This is done more effectively with the pressure controller rather than the CH controller such that the flame structure lacks any organized structure. The Rayleigh integral was forced to be zeroed in the controlled state. It is shown that the suppression is effective when the system operates at a certain range of time delay, gain and filtration. Outside this range vortex roll-up in the shear layer can occur at smaller wavelength, subsequently exciting a high frequency combustion instability. C1 USN,CTR WEAP,RES DEPT,CHINA LAKE,CA 93555.

Even in the most basic scenario, where the underlying system lifetimes are assumed to be independent and identically distributed (iid), the problem of updating maintenance policies using past maintenance history has not been adequately solved. In this paper, Monte-Carlo methods are used to study a particular nonparametric procedure of Aras and Whitaker (1991) which updates an optimal age replacement policy after each replacement. In particular, we will focus on finding conditions under which this sequential procedure does well. C1 UNIV CALIF SANTA BARBARA, DEPT STAT & APPL PROBABIL, SANTA BARBARA, CA 93106 USA.

The model can calculate elastic or nonelastic effective moduli of composites depending on their constituents' behavior. Furthermore, micro-mechanical damage can also be considered in the present model to determine effective moduli. Predicted effective moduli from the present model compared very well with experimental data available elsewhere for both undamaged and damaged composites.

The panels are modeled using the Donnell-Mushtari-Vlasov shell relationships. An approximate solution to the resulting nonlinear equations is constructed using the Galerkin procedure in the spatial domain and the Lindstedt-Poincare perturbation technique in the temporal domain. The combination of these procedures is implemented using the symbolic manipulator Mathematica. The analysis shows that although the transverse displacement may be assumed to have a single mode, the compatibility condition forces the in-plane stress resultants to be multi-modal. It is shown that the type of nonlinearity that the panel exhibits is strictly cubic if either of the axial or circumferential modes is asymmetric. On the other hand, the nonlinearity is both quadratic and cubic for axisymmetric modes. Numerical simulations using various geometric and material properties show that the reponse of the first modes of the panel could be either hardening or softening depending on the geometric and material properties of the panel. On the other hand, the response of the higher modes for the studies cases is always hardening. Numerical results also suggest that it is possible to tailor the dynaMiC response of some panels to produce softening or hardening behaviors.

The tests selected for evaluation were the single-fibre pull-out test, the microdebond test, the fragmentation test and the micro-indentation test. Twelve laboratories were invited to participate in this programme. Each laboratory was supplied with Caurtaulds XA fibre in the untreated condition and with a standard surface treatment, and a quantity of epoxy resin, hardener and catalyst, all from the same batch. Some laboratories were supplied with composite bars made with the same materials. A common cure cycle was chosen for sample preparation. Each laboratory conducted the tests to its own procedures. The results showed that the scatter within each laboratory was acceptable but the scatter between laboratories for a particular test was high. The results are discussed and possible explanations are presented for these observations. The indications are that the fundamental procedures used in each laboratory are sound. The results also suggest that there is great potential for achieving standard procedures and reducing the inter-laboratory scatter. A further round-robin programme is proposed to generate test protocols. C1 OFF NATL ETUD & RECH AEROSP,PARIS,FRANCE. TEXT RES INST,PRINCETON,NJ 08542. DOW CHEM CO USA,MIDLAND,MI 48674.

These include traditional, user-selected passwords, system-generated passwords, passphrases, cognitive passwords and associative passwords. While the mechanisms employed in primary passwords are determined by the operating systems' manufacturers, system designers can select any password mechanism for secondary passwords, to further protect sensitive applications and data files. This paper reports on the results of an empirically based study of passwords characteristics. It provides a comparative evaluation on the memorability and users' subjective preferences of the various passwords mechanisms, and suggests that cognitive passwords and associative passwords seem the most appropriate for secondary passwords.

Rapid prototyping of embedded systems can be accomplished using a Computer Aided Prototyping System (CAPS) and its associated Prototyping Language (PSDL) to aid the designer in handling hard real-time constraints. The language models time critical operations with maximum execution times, maximum response times and minimum periods. The mechanisms for expressing timing constraints in PSDL are described along with their meanings relative to a series of hardware models which include multi-processor configurations. We also describe a language construct for specifying the policies governing real-time behavior under overload conditions. RP USN, POSTGRAD SCH, DEPT COMP SCI, MONTEREY, CA 93943 USA.

A ''simple'' world lends itself to blasting all the polygons through the workstation's existing graphics pipeline. However, a ''simple'' world is not very realistic and/or does not operate in real-time. For complex worlds, such as that modeled in NPSNET, providing high fidelity in real-time requires the use of hierarchical data structures.

We found that when the applied field was below a critical shielding field, H(s), the magnetic field in the interior of the cylinders was zero to within the resolution of the probe. At intermediate fields, between H(s) and several hundred gauss, the Hall probe registered an attenuated response. At much larger fields, the interior field approached the external field. Using a simple equation for J(c) as a function of H(c), we were able to estimate the former for these materials and found good agreement with transport measurements of Jc made on the same samples. In a second set of measurements, we used a SQUID to measure the noise inside these cylinders to assess their merit as electromagnetic shields for SQUID applications. We found that the spectral power density measured for these shields at a temperature of 4 K was no larger than than of a low T(c) (lead) shield and, in fact, was no larger than the spectral power density of the SQUID itself.

These were cut into a rectangular shape with typical dimensions 4.0 cm x 0.5 cm x 0.25 cm. The large physical size of these samples and their ability to carry high currents particularly in zero magnetic field required low resistance contacts to avoid Joule heating at the sample current-electrode interface. Accordingly, low resistance metal contact pads for current and voltage electrodes were applied at NIST Boulder, using a sputter etch, sputter deposition, thermal evaporation and oxygen anneal procedure. Transport critical current density measurements at 77 K, and in magnetic fields up to 6 T were performed at NRL. A holder was designed to hold the samples securely in such a way that would allow for contraction during cool-down and to support them against the anticipated large Lorentz forces. The highest critical current measured with no external field was 393 A. This corresponds to a critical current density of 1871 A cm-2. At 1 T, these values decreased to 229 A or 1090 A cm-2. These critical current values, found in material that was fabricated using a technique capable of being scaled up for larger sizes, demonstrate a potential usefulness in large scale applications.

This invariably leads to comparisons with database theory. Model integration is viewed from four perspectives: Organizational, definitional, procedural, and implementational. Strategic modeling is discussed as the organizational motivation for model integration. Schema and process integration are examined as the logical and manipulation counterparts of model integration corresponding to data definition and manipulation, respectively. A model manipulation language based on structured modeling and communicating structured models is suggested which incorporates schema and process integration. The use of object-oriented concepts for designing and implementing integrated modeling environments is discussed. Model integration is projected as the springboard for building a theory of models equivalent in power to relational theory in the database community.

The construction of complex models can be a challenging task even for expert modelers. The aim of computer-aided model construction systems is to simplify this task. We view model construction as a state transformation process, and suggest that the process can be facilitated by supporting the creation of certain representations or by transforming an existing representation to another. For example, declarative modeling languages facilitate the specification of an executable statement of the mathematical model, while knowledge-based model construction systems assist the creation of the mathematical formulation. Knowledge-based model construction systems are the focus of our review of existing systems. To facilitate a comparison of several such systems, we characterize them in terms of their cognitive bases, the representations developed in them, and the methods for transformation of these representations.

In contrast, only a few factors (most notably retirement benefits) exert a significant influence on women's retention in this part-time job. After accounting for race, gender differences remain important in explaining retention in the reserves. RP THOMAS, GW (reprint author), USN,POSTGRAD SCH,DEPT ADM SCI,MONTEREY,CA 93943, USA.

Forty four of the patients were infected with strains of S. typhi resistant to multiple antibiotics including chloramphenicol, ampicillin and trimethoprim-sulfamethoxazole. All patients responded rapidly to treatment and were cured clinically and bacteriologically. Fever subsided within a mean of 5.3 days (range 3 - 8 days). Only two of the 50 patients treated relapsed during the 8 week follow-up period. No serious adverse reactions attributable to the drug were observed. Cefixime proved to be an effective oral drug in this open treatment trial and was associated with minimal side effects. It may provide a therapeutic alternative to the treatment of Salmonella infection with organisms multi-resistant to the standard drug regimens. Its oral formulation may provide an efficient alternative to parenteral therapy in less severely ill patients who can tolerate oral feeding. C1 ABBASSIA FEVER HOSP,CAIRO,EGYPT.

Within each session, local error rate, defined as the fraction of targets detected in a 33 sec moving window, fluctuated widely, Mean coherence between slow mean variations in EEG power and in local error rate was computed for each EEG frequency and performance cycle length, and was shown by a Monte Carlo procedure to be significant for many EEG frequencies and performance cycle lengths, particularly in 4 well-defined EEG frequency bands, near 3, 10, 13, and 19 Hz, and at higher frequencies in two cycle length ranges, one longer than 4 min and the other near 90 sec/cycle. The coherence phase plane contained a prominent phase reversal near 6 Hz. Sorting individual spectra by local error rate confirmed the close relation between performance and EEG power and its relative within-subject stability. These results show that attempts to maintain alertness in an auditory detection task result in concurrent minute and multi-minute scale fluctuations in performance and the EEG power spectrum.

The latter procedure included testing at three conditions: 43-degrees-C/3 weeks, 65-degrees-C/4 days, and 90-degrees-C/16 h. The yields of total insolubles in these various tests were reasonably consistent. The blends were doped with 0.001 M dodecylbenzenesulfonic acid and with 0.01 M p-tert-butylthiophenol. Deposits formed rapidly from the sulfonic acid doped blends, and the total insolubles were consistent for the various test regimes. One blend containing the thiophenol exhibited a predictable pattern for instability, but the second blend formed more insolubles at high temperatures than expected. On balance, the 90-degrees-C/16 h/OOP stress regime affords good predictability for ambient storage conditions. This conclusion is supported by the data for the two undoped fuels and most of the information from the doped fuels. The insolubles, both adherent (AI) and filterable (FI), were characterized by several chemical analysis techniques. Field ionization mass spectrometry (FIMS) and X-ray photoelectron spectroscopy (XPS) showed that sulfonic acid was incorporated into the insolubles from the fuel doped with sulfonic acid. Nonaqueous titrations also demonstrated that strong acid was present in the sediments. Titration of the blends containing a substituted thiophenol found evidence for partial conversion to strong acid. FIMS analysis demonstrated that p-tert-butylbenzenesulfonic acid was present in the insoluble material thus showing that the multistep oxidation of a thiophenol can proceed under accelerated storage conditions. The thiophenol oxidation to sulfonic acid was a small fraction of overall thiophenol disappearance, and even this fraction was significantly smaller at low stress temperatures. The thiophenol appears to stimulate insolubles by two processes: acting as an acid catalyst after conversion to sulfonic acid and by a free-radical mechanism, possibly by addition of the thiyl radical to olefins.

A molecular model of Zrv-IIB channels is presented. The structure of monomeric Zrv-IIB is based upon the crystal structure of Zervamicin-Leu. The helical backbone is kinked by a hydroxyproline residue at position 10. Zrv-IIB channels are modelled as helix bundles of from 4 to 8 parallel helices surrounding a central pore. The monomers are packed with their C-terminal helical segments in close contact, and the bundles are stabilized by hydrogen bonds between glutamine 11 and hydroxyproline 10 of adjacent helices. Interaction energy profiles for movement of three different probes species (K +, Cl - and water) through the central pore are analyzed. The conformations of: (a) the sidechain of glutamine 3; (b) the hydroxyl group of hydroxyproline 10; and (c) the C-terminal hydroxyl group are ''optimized'' in order to maximize favourable interactions between the channel and the probes, resulting in favourable interaction energy profiles for all three. This suggests that conformational flexibility of polar sidechains enables the channel lining to mimic an aqueous environment. C1 INDIAN INST SCI,MOLEC BIOPHYS UNIT,BANGALORE 560012,KARNATAKA,INDIA.

Transition was determined using a Laser Doppler Velocimeter (LDV). A smooth reference surface was compared to five riblet surfaces for a range of Reynolds numbers. Smooth surface transition Reynolds number was about 2.75 x 10(6). All of the five tested riblet surfaces had lower transition Reynolds numbers. A critical roughness Reynolds number of about 6 was determined for one of the riblet surfaces. This is much lower than the generally accepted value of 25, considered safe for distributed roughness.

Recent work on the interfacial structure of Au single-crystal electrodes has shown the need to merge appropriate electrochemical cell designs to work on standard four-cycle diffractometers. In this report, an electrochemical-based methodology for use of in situ X-ray diffraction from the electrode/electrolyte interface is applied to electrodeposition of Pb on Au(100). The cell in this experiment, unlike traditional reflection cells, provides the necessary electrochemical control of the electrode surface, as determined by the cyclic voltammagram, in conjunction with the X-ray studies. Growth of the Pb monolayer begins with diffusion of Pb+2 ions to the surface at potentials below the Au(00)-(5 x 20) p.z.c. Electrodeposition causes a lifting of the (5 x 20) reconstruction. Pb atoms are deposited on the (1 x 1) surface in a c(2 x 2) structure. Domain sizes are small due to constriction by Au islands formed when the (5 x 20) is lifted. Irreversible surface defects are observed at -0.32 V vs. SCE. Potentials at which Pb on Pb deposition occurs result in a roughened surface and alloy formation.

In the lowest order expression of the overlap potential the ions are spherical. In this simplest form, polarization can result either from ion displacements or from transfer of charge from one ion to another. Calculations for BaTiO3 and KNbO3 show charge transfer from the O(2p) to the transition metal d states, beginning near the equilibrium volume and increasing with increasing volume. Results are obtained which indicate the transfer effect will be greatly enhanced for transition metal ions on a surface. C1 [Boyer, L. L.; Mehl, M.

We find large static displacements of all atomic species from their ideal cubic perovskite sites producing a long-range average structure consistent with a crystallographic disorder model, however local correlations of these displacements are significant. Two distinctly different B cation environments are found, as are two unique environments for Pb. The model suggests the formation of structurally ordered regions in which the two types of B cation environments are 1:1 ordered. Details of this model for the local atomic structure of PMN and how it was obtained are described. C1 Univ Penn, Dept Mat Sci & Engn, Philadelphia, PA 19104 USA.

We consider the existence of weight-balanced measures and large deviation properties of the Free-Energy of the Jacobian of measures. We show that a weight-balanced measure exists under the hypotheses that the map is piecewise-homeomorphic and the weights piecewise constant. We consider also a certain class of measures with the property that the Free-Energy of the Jacobian is differentiable by parts. For measures in this class we show that a certain measure is the maximal entropy measure if and only if the Free-Energy of the Jacobian is linear. The result follows from general properties of Large-Deviation Theory and does not use the more classical approach of Thermodynamic Formalism. C1 USN ACAD,DEPT MATH,ANNAPOLIS,MD 21402.

Slump scars, evident as amphitheater headwalls, are a good morphological indicator where a landslide has occurred. Radical changes in the lower flank slope angles are also good indicators. Debris flows can be surmised by hummocky topography, with the larger blocks being nearer the main edifice. A cursory inspection of the Pacific plate from younger to older shows: (1) the Hawaiian-Emperor Ridge from Loihi to Suiko at 65 Ma, where the lower flank slopes increase with age, (2) Mammerickx seamount in the Mapmakers on 140 Ma crust, out of the fractured region, still showing moats and having no sign of landslides, (3) Castor and Pollux guyots of the Michelson Ridge on 150 Ma crust, where the debris field size is added to or overprinted by later volcanics, to (4) Hunk, Jennings, and Jaybee guyots in the Marcus-Wake seamounts on 160 Ma crust, where later fracture zone formation may have helped form landslides. None of the older seamounts have been dated. Three-dimensional views aid in the location and description of landslides.

The mathematical description of this behavior is complicated by the interruption of the cycle for 75 years starting around 1650. Similar previous intermissions of this kind are implied by the available data. We explore the possibility of modeling such temporal variations of the sunspot number with a deterministic dynamical system of relatively low order. The system we propose manifests on/off intermittency in which the cyclic variations of the solar activity switch off almost completely for extended periods. We also offer an explanation of the variation of the fluctuating part of the sunspot number over the cycle. C1 COLUMBIA UNIV,DEPT ASTRON,NEW YORK,NY 10027.

Peripheral blood mononuclear cells (PBMC) from sexually inexperienced and experienced women that were antisperm antibody (ASA) negative gave rise to a plaque-forming cell (PFC) response of similar magnitude (1,362 and 1,254 PFC/culture, respectively). PBMC from women that were ASA positive had lower PFC responses if cervical mucous antibodies were detected along with circulating antibodies (876 PFC/culture) than if they were not detected (1,512 PFC/culture). Limit dilution analysis was used to demonstrate that the level of the anticipated antibody response is regulated by T helper cell activity.

The difficulties associated with the use of acoustics in the ocean, however, are aggravated in shallow water. Multipath propagation and extensive boundary interactions, especially with the sea bottom, conspire, along with a host of other phenomena, to produce a highly variable and often unpredictable acoustic field. The responsible mechanisms, and hence the acoustic effects, cover a wide range of temporal and spatial scales. The mechanisms are classified as either deterministic or random, although the two types often act in concert. The sea bottom plays a dual role in shallow-water acoustics. Because of extensive interactions with the sound field, the bottom can severely degrade waterborne propagation. On the other hand, the sea bottom (and subbottom) can provide a seismic path that not only is relatively stable, but exists even under environmental conditions that preclude an effective waterborne path. Propagation in the bottom is particularly significant at very low frequencies, often being more efficient than high-frequency waterborne propagation. The preceding aspects of shallow-water acoustics-viz., variability and the dual role of the sea bottom-are illustrated using the results of experiments conducted in diverse geographic areas by the Naval Research Laboratory/SSC and by the SACLANT Undersea Research Centre.

The OPO is based on intracavity pumping of a KTiOP04 (KTP) crystal in a colliding pulse mode-locked dye laser, and produces femtosecond pulses at a 90 MHz repetition rate at average powers of 22 mW at 620 nm and 1-2 mW in the infrared. A model is synthesized from existing laser and parametric oscillator theories, and numerical simulations reproduce some qualitative aspects of the parametric oscillator's behavior. The theory accurately predicts the renormalization properties of the pump pulses in the presence of a nonlinear intracavity loss, and the existence of megahertz intensity oscillations on the output power envelope for excessively self-phase modulated pump pulses.

This exact expression requires computer assistance in order to be evaluated. Here, a ''rule of thumb'' expression is derived which is a good approximation to the exact expression. Furthermore, this same approximation can be used to derive a good approximation for the canceler noise power level which is induced by having a desired signal present in the canceler weight calculation. An expression for the number of independent samples necessary to equalize the signal-induced power with the quiescent interference level is derived.

The end-to-end model is comprised of a component that models the power supply, a component that models the plasma injector, and a component that models the interior ballistics processes. Appropriate coupling conditions are applied at the interfaces between the component models in order to make the end-to-end model self consistent. The component models are made modular so that models with varying degrees of complexity can be interchanged as needed for resolution. After describing the development of the end-to-end model we illustrate its use to analyze experimental results using two different levels of interior ballistics models. First, we use a control volume model of the interior ballistics process to simulate a test firing. Then, we illustrate the resolution that can be achieved with a two-dimensional model of the interior ballistics. C1 USN,DIV SYST,FMC,MINNEAPOLIS,MN 55421.

The solutions to these problems will come from existing industrial specifications, tailored to the unique demands of the military environment. This paper reviews shipboard practices and philosophy for low voltage systems and projects how this philosophy will lead to the selection of a grounding architecture for an electric gun system. The shipboard standards for routing dedicated, redundant, and survivable distribution systems are also reviewed.

In some cases, a dedicated and properly sized power supply may be feasible to provide adequate electric gun system performance. However, in many cases the prime power source must be shared with the ship's propulsion system due to limits in available ship space, allowable weight, and cost. In both of these instances, the dynamics of the propulsion power supply may have significant effect on the performance of the EM or ETC gun. This paper examines the dynamic simulation of an ETC gun system utilizing capacitor based energy storage and gas turbine prime power. A comparison of system response for both dedicated and shared prime power source configurations confirms that both modes are feasible.

Gas turbine mechanical and gas turbine Integrated Electric Drive (IED) propulsion trains are considered as prime power sources. Focus is on the energy path between the ship's prime power and the pulsed load, comparing system candidates on a size, weight and component cost basis. A capacitor-based Pulse Forming Network (PFN) supplying an Electro-Thermal Chemical (ETC) Gun is utilized as the common load for all configurations. Results indicate that dedicated auxiliary generators driven from propulsion gas turbine engines is the preferred method of powering electric gun PFNs from ship drivetrain equipment. Auxiliary generator-based systems are compact and lightweight over a wide power range, are equally attractive with both electric and mechanical drive trains and demonstrate retrofit potential to the current fleet.

It is shown that by appropriate grouping of terms, feedforward neural networks with sigmoidal activation functions can be viewed as architectures which implement affine wavelet decompositions of mappings. This result follows simply from the observation that standard feedforward network architectures possess an inherent translation-dilation structure and every node implements the same activation function. It is shown that the wavelet transform formalism provides a mathematical framework within which it is possible to perform both analysis and synthesis of feedforward networks. For the purpose of analysis, the wavelet formulation characterizes a class (L2)of mappings which can be implemented by feedforward networks as well as reveals an exact implementation of a given mapping in this class. Spatio-spectral localization properties of wavelets can be exploited in synthesizing a feedforward network to perform a given approximation task. Synthesis procedures based on spatio-spectral localization result in reducing the training problem to one of convex optimization. We outline two such synthesis schemes.

In this correspondence, we point out that, in general, especially with correlated data, the unconstrained algorithm may have a significant performance advantage in steady state if block mean square error is the criterion. Furthermore, we point out here that, in the constrained algorithms, the choice of different step sizes in different frequency bins (as is commonly done) will very likely result in a deterioration of steady state performance. This does not happen in the unconstrained algorithm. C1 USN,POSTGRAD SCH,DEPT ELECT & COMP ENGN,MONTEREY,CA 93943.

Using the critical tracking (CT) task, five subjects were tested at 10-degrees, 20-degrees, 40-degrees, 80-degrees, and 120-degrees FOV. The measured ''effective'' time delay (tau(e)) declined exponentially as the FOV increased with two of five subjects nearly reaching their minimum tau(e) with a FOV as small as 40-degrees and three subjects reaching or nearly reaching their minimum tau(e) with a FOV as small as 20-degrees. The corresponding root-mean-squared (RMS) error followed a U-shaped curve with the majority of the RMS reduction at 40-degrees FOV followed by an increase at 120-degrees. This increase in RMS error was accompanied by the subjects' reports of increased task difficulty at 120-degrees FOV. We hvpothesize this increased RMS error was due to the episodic vection, reported only at this FOV, that briefly disoriented the subjects and thereby distracted them from the tracking task. A second experiment, where two subjects were tested at 10-degrees, 40-degrees, and 120-degrees FOV, used a time-invariant plant to allow the measurement of human describing function parameters. The crossover frequency increased at least 5% and the RMS error dropped by at least 20% at a FOV of 40-degrees or 120-degrees compared to 10-degrees. The results from these two experiments show that a FOV as small as 40-degrees can produce performance improvements of the same magnitude as a FOV as large as 120-degrees. The final experiment was identical to the CT experiment, described previously, except that only the central 10-degrees of the scene rotated. Unexpectedly, performance was best at 10-degrees and poorest at 40-degrees and 80-degrees, just the opposite of the previous two experiments. These results may be due to a ''contrast motion vection'' effect first reported during circularvection experiments. C1 USN,OCEANA NAVAL AIR STN,VIRGINIA BEACH,VA 23451.

The model is valid when the lateral spatial scale of the composite is sufficiently fine that the composite can be treated as an effective homogeneous medium. Expressions are derived for the composite's material parameters in terms of the volume fraction of piezoelectric ceramic and the properties of the constituent piezoelectric ceramic and passive polymer. The results are similar to those derived by Haun and Newnham using a parallel-series connectivity model. The model is illustrated by analyzing composites made from conventional PZT5 and anisotropic modified lead titanate piezoelectric ceramics. For PZT5, the composite structure enhances its hydrostatic charge coefficient, d(h)BAR, hydrostatic voltage coefficient, g(h)BAR, hydrophone figure of merit, d(h)g(h)BAR, and hydrostatic coupling coefficient, k(h)BAR, while three of these quantities fall short of their pure ceramic values in the modified lead titanate composites. The shortfall is due to an enhanced composite d31BAR that arises from lateral stress on the polymer being transferred to a longitudinal stress along the ceramic rods by the Poisson effect in the polymer, thus producing a charge through the ceramic's d33.

In this paper we show how such locks can be used for concurrency control, without introducing covert channels. C1 USN,RES LAB,WASHINGTON,DC 20375.

A kinematic model is developed for the manipulator, its relationship to the world coordinate frame and the tool. The derivation of the tool pose from experimental measurements is discussed, as is the identification methodology. A complete simulation of the experiment is performed, allowing the observation strategy to be defined. The experimental work is described together with the parameter identification and accuracy verification. The principal conclusion is that the method is able to calibrate the robot successfully, with a resulting accuracy approaching that of its repeatability.

In fact, however, while it is true that values of large measure games will, under certain reasonable circumstances, converge to the value of a non-atomic game, it is also true that this convergence is quite slow. Using the multi-linear extension and the central limit theorem, we obtain an approximation which (because it is based on the normal distribution) we call the normal approximation. We show that, for two examples with several hundred and several thousand players respectively, the normal approximation is much better than the non-atomic approximation.

Earlier work with this model showed that a ''bubble'' of propellant debris forms in the air gap between energetic material layers (bore region) as a result of projectile penetration of one of the layers. Ignition of the bubble occurs upon impact with the second layer, followed by a reaction ranging from mild burning to delayed detonation, depending on the width of the air gap, properties of the energetic material, and degree of confinement. The present paper presents the results of experimental and hydrocode studies to characterize the latter (delayed detonation) reaction. Results show that reaction initiates in the frontal portion of the bubble wall through mechanical (impact) shock. It then propagates backward through the bubble wall towards the first layer which then detonates. Detonation of the second layer occurs sympathetically. The reaction is bounded by a lower velocity limit and confined within a range of air gaps that increases with impact velocity. The upper-air-gap limit roughly coincides with the maximum expansion distance for the bubble before breakup, while the lower limit represents the minimum (threshold) damage level for detonation.

The projectiles were strong rods, length to diameter ratio of 6 to 10, prepared from aluminum (10 tests) or steel (5 tests), launched at velocities of 4.2 to 4.8 km/s, and impacted into like material targets. The rods had little or no initial yaw (the average yaw was 1.8-degrees). The residual projectile properties of length, tumbling rate and radial velocity were measured and evaluated in a simple model for rod tumbling. The model is based on the observation that plastic shear continues at the nose of the rod for a finite time after target perforation. Based on the observed tumbling rate, duration of plastic flow and the inertia of the residual rod an implicit determination of the shear strength of the rod was obtained. The calculated shear strength was in fair agreement with static shear values. C1 POTOMAC RES INC,ALEXANDRIA,VA 22312. RP PERSECHINO, MA (reprint author), USN,RES LAB,WASHINGTON,DC 20375, USA.

The experimental study involved the impacts of three compact projectiles, L/d = 1, of two materials (Graphite epoxy, and aluminum) at 3 and 6 km/s with three thicknesses of aluminum plate. The test matrix was tailored to explore the effects of such impact variables as plate thickness, impact speed and projectile properties on characteristics of the debris cloud. A few tests were dedicated to scaling. While most of the results were expected, some were interesting and unexpected. C1 POTOMAC RES INC, ALEXANDRIA, VA 22312 USA.

The experiments involved single steel spheres fired at a steel shatter plate at speeds near 1.5 and 2.0 km/sec to generate the debris clouds. In each series of tests, the impact velocity was controlled, and a witness plate was placed at increasing distances behind the shatter plate to observe the effects of debris particle dispersion on plate damage. This paper focuses on the variations, with plate spacing, in the size of the central region removed from the witness plates. The central hole size model compares the post impact kinetic energy distribution in a witness plate impacted by a debris cloud to the free impact residual kinetic energy in an equivalent plate impacted by an L/D=l steel cylinder, at the ballistic limit velocity. This approach permits extension of the model to other plate materials through utilization of existing ballistic limit velocity data. C1 USN,CTR SURFACE WARFARE,DAHLGREN,VA 22448.

The analysis assumes polycrystalline materials which usually contain microvoids with an average density of the order of 10(6) per cm3 that are dispersed homogeneously throughout. It is shown that for dynamically imposed loading that produce nominal strain rates ranging between 5 X 10(2)-5 X 10(3) sec-1, the inhomogeneous fields of stress and deformation caused by wave propagation and wave reflection induce necking at different locations along the gauge section, depending upon the strain-rate imposed. This occurs without imposition of any geometrical or material irregularity to preposition the location of the necking. The imposed rate of strain is also shown to affect the magnitude of the strain at which necking initiates, as well as the strain required for fracture.

Specifically attempts to determine which Public services were most likely to be responsive to increases in the foreign population. Were these services provided to both Arab and Asian workers alike or were the patterns of supply somewhat different by nationality? Did public services adjust quickly to increases in the foreign population or were the increased provisions spread out gradually over time? Mainly finds that, despite the early post-liberation statements of Kuwaiti officials, it will not be possible to dispense entirely with foreign workers. There is a good chance, however, that the Government's political policy of replacing Palestinian workers with those from Asia will provide the unintended benefit of considerable budgetary savings.

The base dopant levels ranged from 3 X 10(15) to 2 X 10(17) cm-3, and the effect of the dopant concentration on the radiation response is presented and analyzed. The radiation-induced degradation of the solar cells was measured through both dark and 1 sun air mass zero current-voltage measurements and through spectral response measurements. The radiation-induced defects in the solar-cell junction were monitored by deep-level transient spectroscopy. Thermal and photoinjection annealing experiments were performed on the irradiated cells. The highest postirradiation efficiencies measured after a fluence of 10(16), 1 MeV electrons cm-2 were 11.6% which is higher than has been reported for any other solar-cell material. Although all of the cells showed high radiation resistance, the cells with a lightly doped base (essentially an n-i-p structure after irradiation) degraded more in the open-circuit voltage and less in the short-circuit current than the more heavily doped cells. Modeling indicates that the thickness of the junction and base layers is very important in determining the end of life efficiency of the cell. Using the measured data, efficiencies up to 14.1% are predicted with a thin base and a back surface reflector, following irradiation with 10(16) 1 MeV electrons cm-2.

Controlled continuous removal of silicon does not result in a continuous PL blueshift, which would be expected in the quantum confinement model. Also, high temperature (1200-degrees-C) anneals of porous silicon lead to a material consisting of 100-200 nm silicon spheres, with very low dangling bond densities, similar to crystalline silicon. This material does not exhibit noticeable PL in the visible range but when dipped in hydrofluoric acid (HF) for 1 s, strong visible PL appears with no structural changes noted. Polysilane/hydride complexes appear with the HF treatment, leading to the conclusion that the visible PL may be the result of a surface phenomenon related to the polysilane/hydride complexes, and not to a bulk Si quantum confinement effect. Anneals of porous silicon to 690-degrees-C also show a significant redshifting of the PL, exhibiting identical behavior to measurements of shrinking of the optical bandgap of hydrogenated amorphous silicon (a-Si:H). With these results in mind, a surface related polysilane luminescence mechanism in porous silicon will be discussed, in which the PL energy is a function of H content and the PL intensity is a function of total surface area.

Films were prepared independently from four amidoamines containing increasing proportions of imidazoline, under dry conditions, and in the presence of water. The intensity of fluorescence increased during curing, and the reaction rate and maximum fluorescence intensity were found to be inversely proportional to the imidazoline content of the amidoamine. FTIR measurements showed that hydrolysis of epoxy and imidazoline rings is slow compared to reaction between the amine and epoxy groups. Fluorescence properties of the cured films were studied as a function of temperature over the range -8 to 75-degrees-C. Two temperature-dependent radiationless processes from the singlet state were observed, with activation energies which depend on the imidazoline content of the amidoamine. Arrhenius plots of fluorescence intensity showed a distinct discontinuity near 32-degrees-C which is not affected by imidazoline content. The discontinuity correlates with the dynamic mechanically observed glass transition and is due to increased radiationless thermal deactivation of the singlet excited state, possibly by motion of alkyl chains in the polymer.

The analysis was performed to determine if the reduction in strength was an intrinsic thickness material effect or if it could be attributed to through-thickness restraint on the specimen caused by the test fixture. The analysis was based on closed form solutions for the formation of kink-band failures in the presence of fibers misaligned with the principal axis of compression loading. The fiber misalignment was determined by a finite element analysis that accounted for the displacement of the laminate outer plies where the laminate exited the compression test fixture. The correlation between the experimental results and the theoretical analysis showed the compression strength of the AS4/3501-6 and S2/3501-6 laminates to be independent of thickness and directly proportional to the through-thickness fixture restraint on through-thickness Poisson expansion. This theoretical and experimental comparison also demonstrated a strong correlation between fiber misalignment, its resulting shear stress state and the kink-band compression failure mechanism.

Relationships are observed between the degree of non-uniformity and fiber spatial information which may be measured via image analysis or derived from Dirichlet cell tessellations. For artifical patterns containing chain-like clustering which simulate composite microstructures: (a) the nearest-neighbor distances of random and clustered patterns are smaller than those normally estimated by square or hexagonal arrays, (b) increased clustering may be associated with increased mean cell volume fraction, cell volume fraction distribution standard deviation, number of cell sides, distribution standard deviation, nearest-neighbor distance distribution skewness, and decreased nearest-neighbor distances and (c) accounting for non-uniform fiber diameters is generally unnecessary, except possibly at low fiber volume fraction or with patterns exhibiting a high degree of chaining. For Nicalon SiC/zirconia titanate composite samples with microstructures which exhibit clustering, the maximum value of skewness, determined from sub-regions of the sample, correlates with the flexure strength of that sample.

Calculations of the thermal stresses for various fiber coatings reveal certain relationships between the coating stresses that make it possible to solve for the plastic flow of the coating. In the case of a high expansivity coating, the elastic solution indicates that the radial and hoop stresses are the extreme stresses which satisfy the conditions for Tresca flow in the r-theta plane. However, as the temperature changes, plastic flow is shown to relax the hoop stress to the extent that it becomes less than the axial stress which violates the condition for Tresca flow. In order to obtain solutions for plastic flow in the coating it is then necessary to consider plastic flow in more than a single plane. The Prandtl-Reuss flow rule can be used to solve for flow in three planes but because of the mathematical complexity it is necessary to use numerical techniques for the calculations. As an alternative, analytical solutions are developed for flow in two planes using an approximation for the Prandtl-Reuss flow. Three different solutions are obtained to include flow in the r-theta r-z, z-r z-theta, and theta-r theta-z planes. Each of these is applied for a different expansivity value of the fiber coating with various linear work hardening coefficients of the coating.

This assumption has to be evaluated or validated. The objective of this article is to address the subject of vibration characteristics and the related force transmissibility properties of composite structures. For a given composite beam made of Hercules AS4/3501-6 graphite/epoxy with a layered structure sequence of (0,0,30, - 30)6S, resonance frequencies, structural damping, responses, impedances, and force transmissibility properties are determined, discussed, and compared with those of a steel beam. This article proposes a procedure to evaluate the vibration properties of individual composites. The criterion defined for performance comparison between composite materials and conventional materials is also discussed.

However, TMIn suffers from several problems. First, it is well known that the effective vapor pressure of solid TMIn changes with time because of changes in the surface area. Secondly, TMIn decomposes slowly for temperatures lower than 400-degrees-C in an atmospheric pressure OMVPE reaCtor; it is too stable for some low-temperature applications. In addition, it causes carbon contamination, especially at low temperatures, due to the CH3 radicals. Thus, there is a need for new In precursors that are liquids at room temperature and do not contain CH3 radicals. This work reports the first decomposition and OMVPE growth studies for a newly developed indium source, triisopropylindium (TIPIn). The decomposition study was carried out in an isothermal flow tube reactor with the reaction products analyzed using a mass spectrometer. The temperature for 50% decomposition is approximately 110-degrees-C for TIPIn in a He ambient. This is about 200-degrees-C lower than that for TMIn under SiMilar conditions. The mass spectroscopic peaks occur at m / e = 39, 42, 43, 71, and 86. The relative intensities indicate that the major product for TIPIn decomposition is C6H14. This suggests that TIPIn decomposes by homolysis, producing C3H7 radicals that mainly recombine to produce C6H14. The OMVPE growth study was carried out in an atmospheric pressure OMVPE reactor in H-2 with AsH3 as the As source. InAs epilayers with good surface morphologies were obtained for temperatures as low as 300-degrees-C at a V/III ratio of 460. The necessary V/III ratio increases as the growth temperature is decreased, due to the incomplete decomposition of AsH3 at low temperatures. The less reactive C3H7 radicals from TIPIn pyrolysis produce far less carbon in the solid than the more reactive CH3 radicals produced by TMIn pyrolysis. A disadvantage of TIPIn is the low growth efficiency, due to parasitic reactions. Thus, it appears that TIPIn may be best suited for low pressure OMVPE or, particularly, for chemical beam epitaxy.

The guidance condition requires that the eigenfunction of a mode is independent of these two different computation procedures. This requirement can be used for checking the accuracy of numerical computation. When significant discrepancies between these two procedures were observed during a recent revision of a waveguide mode based tropospheric propagation program, it was found that one of the two procedures converged to the mode eigenfunction much faster. This consistency condition has been utilized successfully to relax the requirement on eigenvalue accuracy by identifying the procedure which converges to the correct mode eigenfunction faster.

Three kev theories have been proposed to explain the phenomenon: hydrodynamic instability, conjugate states and flow stagnation. Despite a considerable amount of theoretical and experimental investigation, there is still nothing approaching a completely satisfactory theory of vortex breakdown. In addition, there is no agreement on a complete physical description of the structure of vortex breakdown. The present experimental investigation may substantiate a few earlier conjectures. We discuss an experimental finding that might help clarify the phenomenon through the use of flow visualization and laser-Doppler velocimetry. Experimental measurements substantiate earlier measurements and theoretical calculations of the velocity field. The evidence suggests that there is a connection between criticality and instability.

An earlier paper showed that particle motion in a class of x-dependent Harris-like equilibrium models can be significantly different from the motion in x-independent magnetotail field models. In the present paper, it is shown that these Harris-like equilibrium models have ''bulb-shaped'' field lines and that this property leads to the reported differences. Furthermore, it is shown that the scale length of variation of the Harris-like models in the x direction, L(x), is comparable to the typical excursion distance, DELTA, of particles in the x direction and to rho(n) which is the gyroradius based on the magnetic field component B(n) normal to the plane of the current sheet. It is argued that neither bulb-shaped field lines nor scale lengths L(x) comparable to DELTA or rho(n) apply to the Earth's magnetotail. It is suggested that a key criterion for applicability of x-dependent models to the terrestrial magnetotail is DELTA, rho(n) much less than L(x).

It is only required to solve a single linear program to test whether the sufficient conditions are satisfied. This test has been incorporated into an earlier algorithm to give improved performance. Computational results presented show that these sufficient conditions are satisfied for certain types of problems and may substantially reduce the effort needed to find and recognize a global minimum.

The isoelectric points of these isoforms differ by 0.01 to 0.03 pH units. In this study we show that these isoforms can be resolved by capillary zone electrophoresis (CZE) using non-treated capillaries. CZE analyses can be performed on as little as 5ng of protein. Needle-like crystals of natural fibrolase were harvested and their composition analyzed by CZE which revealed the same ratio of isoforms in the crystals as was found in the sample of natural enzyme. Recombinant fibrolase was shown to contain at least two isoforms which could be resolved by cation-exchange HPLC. Analysis by CZE revealed that the early eluting fraction from cation-exchange HPLC contained only one isoform and this isoform corresponded to one of the isoforms of natural fibrolase. The late eluting fraction contained two components when analyzed by CZE. CZE and enzymatic activity measurements were used to assess the effects of metal replacement on fibrolase following EDTA titration. To stabilize the enzyme, 4M urea was added to the buffers used for electrophoresis. This minimized intermolecular interactions which appeared to occur after removal of zinc. It was shown that a 30 minute incubation in 10mM EDTA completely removed zinc from the enzyme. CZE has been shown to be a powerful tool for the analysis of protein isoforms and is useful in assessing the interactions between proteins and metal ions. C1 BECKMAN INSTRUMENTS INC,COLUMBIA,MD.

These coatings exhibit excellent wear and corrosion resistance; however, the significance of microstructure on properties has not been reported. This study relates the structure of the sprayed coatings to the processing conditions. X-ray diffraction results indicate phase separation in air plasma sprayed deposits, while low pressure plasma sprayed deposits exhibit a single supersaturated solid solution. Annealing of the air plasma sprayed coating shows dissolution of the bcc chromium phase, confirming its metastable nature. These results were confirmed using Extended X-ray Absorption Fine Structure (EXAFS) analysis, which further suggests a highly disordered structure, with partial oxidation of selected alloying elements, such as chromium. Transmission electron microscopy indicates a wide variety of microstructures in the air plasma sprayed deposit. In the case of low pressure sprayed deposit, the microstructures are homogeneous and uniform. C1 USN,RES LAB,WASHINGTON,DC 20375. SANDIA NATL LABS,ALBUQUERQUE,NM 87185. SFA INC,LANDOVER,MD 20785.

The method uses a stereo pair of photomicrographs taken in a scanning electron microscope and digitized for computer analysis. The computer can automatically compare the offset at many places in the two images and calculate their height on the basis of the parallax angle. The sum of the area of all planes formed by an array of three-dimensional points is an approximation of the true surface area. The scale can be varied both in the microscope and in the computer; therefore, a fractal dimension can be calculated. Unlike previous methods, this one is direct and gave results intermediate between two prior indirect measurements. C1 USN,RES LAB,WASHINGTON,DC 20375.

Previous studies in immunocompetent hosts and normal adults have demonstrated the value of intravenous acyclovir in the treatment of varicella-zoster virus infections. Oral acyclovir has also shown efficacy in both normal adults with zoster (shingles) and immunocompetent children with varicella. A recently completed double-blind placebo-controlled study of oral acyclovir in immunocompetent adults with uncomplicated varicella also demonstrated efficacy. Therapy within the first day reduced the time to 100% crusting of skin lesions from 7.4 to 5.6 days, and reduced the duration of fever by one-half day. Symptoms were also diminished. These benefits were observed only when therapy was initiated within 24 hours of the appearance of the rash. Adults with complicated varicella (usually symptomatic varicella pneumonia) should receive intravenous acyclovir. Several new agents for varicella-zoster therapy are being evaluated; brovavir is a new agent currently being compared to placebo in the treatment of adult varicella.

In addition, we examined the relationship of hip flexion contractures to development of spondylolisthesis and low back pain. Three patients who had undergone previous spine operation were eliminated from the study group. Of the remaining 47 patients, one patient (2%) demonstrated an asymptomatic grade I spondylolisthesis. Another patient (2%) demonstrated spondylolysis without spondylolisthesis. Only six patients reported occasional low back pain. Pain did not correlate with increasing age, increasing hip flexion contracture, or decreasing sacrofemoral angle. The incidence of spondylolisthesis in this group of ambulatory CP patients with hip flexion contractures is similar to that in in the general population. Hip flexion contractures did not predispose the group to spondylolisthesis or low back pain. Periodic screening of asymptomatic ambulatory CP patients for spondylolisthesis is not recommended.

The study group consisted of 10 patients. Prior to treatment, the palato-gingival groove on maxillary lateral incisors was measured with calibrated periodontal probe from the cemento-enamel junction (CEJ) to the free gingival margin (FGM) and from the FGM to the base of the pocket (BP). Probing depth (PD) was calculated and bleeding on probing indicated. Surgical procedures consisted of flap reflection, removal of granulation tissue, and scaling and root planing of the groove. An expanded polytetrafluoroethylene membrane was sutured over the palato-gingival groove. Six months postsurgery, all measurements were repeated. Statistical analysis compared results using means, standard deviations, and paired t tests. Results showed an improvement in clinical attachment gain, probing depth reduction, and decreased bleeding on probing. This study demonstrates the potential of guided tissue regeneration in the treatment of palato-gingival groove defects. A random blinded clinical trial is necessary, however, to fully assess the potential of this procedure in treatment of palato-gingival groove defects.

These new methods include an improved shock-expansion theory, an improved modified Newtonian theory, and an improved method for angle-of-attack effects. Comparison of these approximate engineering techniques to inviscid computations using a full Euler code showed that these new methods gave very good agreement of inviscid surface temperature and pressures as well as forces and moments. Incorporation of this new technology into the Naval Surface Warfare Center Dahlgren Division aeroprediction code will allow the code to be used for engineering estimates of inviscid surface temperature at high Mach numbers. These approximate temperatures can then be used as inputs to perform heat transfer analysis. C1 N CAROLINA STATE UNIV,DEPT AEROSP,RALEIGH,NC 27695.

The dynamic strain response of the magnetostrictive oscillator was observed with a high-resolution fiber optic interferometer. The effects of low-frequency modulation and band-limited stochastic fluctuations on such a bifurcation are investigated. Power spectral density measurements show that for an optimal value of externally injected noise the signal-to-noise ratio of a low-frequency modulation signal is enhanced by greater than 14 dB, thus indicating the first experimental observation of stochastic resonance near a bistable period-doubling bifurcation.

The formulas do not require any side computations such as numerical zero finding or numerical integrations. The simplest result obtained provides a good estimate of the Green's function for a very broad range of frequencies, being degraded only near the coincidence frequency. A somewhat more complicated formula, almost uniformly valid in frequency, and yielding reasonable accuracy even at coincidence, is also presented. Numerical results comparing the asymptotic approximations to the ''exact'' Green's function are presented, and show significant improvement over a basic steepest descents based approximation. For large values of x, very high accuracy can be achieved with relative errors of less than 0.1 %. For other less stringent applications the approximations are accurate to within 10% at fairly small distances from the source, requiring only k(f)x > 1 and k(o)x > 0.5.

The boundary-element method is applied to compute an operator relating the pressure on a small measurement surface located near the structure to the normal velocity at all points on the structure surface. Since the inverse problem of the reconstruction of the surface field is ill posed, singular value decomposition is applied to invert the operator. It is demonstrated that the surface field may be reconstructed over the portion of the structure surface located under the measurement surface.

Using an approximate theoretical model in which shell membrane waves are explicitly represented, it is shown that the high levels of backscattering are due to supersonic membrane waves that are established on the shell. The loci of peaks are associated with combinations of frequency and angle at which a plane wave incident upon a similar infinite shell generates a resonant membrane mode of the infinite shell. The locations of the discrete high level spots along the loci correspond to those axial wave numbers that, together with the corresponding circumferential wave number, define resonant modes of the finite shell. The level of backscattered pressure is high at these locations because, at these frequency-angle combinations, the particular resonant mode is driven by a trace-matched incident wave. The analysis is given for a simply supported shell, but the nature of the approximations make the approach applicable to other homogeneous end conditions.

The Kirchhoff and the Keller approximations are used in various different combinations to produce plots of the target strength (TS) versus incidence angle for purposes of comparison. The angular scattering patterns which result from the combination of methods considered here, agree fairly well away from the broadside incidence where the strongest differences appear. It is felt that some of the predictions of these combinations of methods represent good estimates for the numerical solution corresponding to an elastic cylindrical shell with flat ends and N internal ribs. This paper derives all the formulas used and compares the predictions they yield in various graphs. C1 USN,CTR SURFACE WARFARE,DAHLGREN DIV,RES DEPT,SILVER SPRING,MD 20903.

Matched-field/mode processing could in principle be used to localize the surface and bottom scatterers separately except that these methods assume pointlike sources whereas in reality the scatterers are extended objects. To develop an appropriate processing method for scattered returns from extended objects, one needs a closed form expression for the scattered field (the replica field). Such an expression in terms of normal mode amplitudes was recently derived by Ingenito [J. Acoust. Soc. Am. 82, 2051-2059 (1987) ] for a rigid sphere in an iso-velocity fluid medium. This expression is generalized to more general cases and also to treat scattering from boundary protuberances in this paper. Based on the normal mode expressions of the scattered field, matched-mode processing is extended to localize the boundary scatterers. The effectiveness of this method is evaluated using simulated data. It is indicated how this method could be used to acoustically image/map the surface and bottom features in a basin-wide ocean.

Using Lie brackets, the singular control is derived and expressed in a state feedback form. The totality of extremals indicates that a forced Keplerian motion obtained by thrust-drag cancellation is not optimal for any Mayer performance criterion. In addition, this paper proves two theorems establishing limits on the optimality of bang-bang control for such a system, and develops a heuristic for the sufficiency of bang-bang optimal control. A sample problem of optimal orbital maintenance indicates the importance of thrust-vectoring for greater propellant efficiency. C1 PENN STATE UNIV,DEPT AEROSP ENGN,UNIV PK,PA 16802.

The main idea is to establish a stabilizing control law using a Lyapunov approach and introduce some optimality condition for a particular control objective, and then optimize over the stable region of the free parameters in the control law. Our approach for designing the optimal control law consists of two stages. The first stage is to find a stabilizing form for the control law as a function of design parameters which are usually feedback gains. In the second stage, the control law is reshaped with the design parameters to satisfy an optimality criteria. Two kinds of control schemes, constant gain feedback and tracking type control laws, are discussed to establish different perspectives on the optimization. The optimization scheme used in this work is a sequential nonlinear programming algorithm which uses a homotopy method to sweep through a sequence of minimum norm design parameter changes. Our results show how our controlled performance is improved by optimizing the parameters appearing in the reference trajectory as well as the associated tracking feedback control law.

It is found that each of the four distinct electric field pulses which the transmitting dipole radiates, induces four distinct (although overlapping) voltage pulses at the discontinuities of the receiving dipole antenna. Although the exciting voltage is single-cycle, the time duration of the incident electric field and the induced received voltage is lengthened by 1.5 cycles and up to 2 cycles, respectively. The receiving antenna behaves like an integrating circuit. The spectra of the short-pulse radiated field and the received voltage have peak values at frequencies higher than the carrier frequency f0 of the exciting single-cycle sinusoidal voltage.

These plasmas were generated at 1.33 Pa using selected ratios of CO:H2 and CH4:O2:H2 that produced the highest quality films (i.e., high degree of faceting and an intense Raman peak at 1332 cm-1). Electron temperature, ion density, plasma potential and B-field profiles obtained at optimum growth conditions are presented. The best diamond films were produced on silicon (100) substrates biased to +40 V dc and maintained at a constant temperature of 500-degrees-C. These substrates were placed downstream of an electron cyclotron resonance (ECR) layer (the region of high plasma density created by resonant microwave absorption at the 87.5 mT B-field contour), characterized by a T(e) near 1 eV and ion densities near 4 x 10(12) cm-3. Actinometry was used to quantify the optical emission spectra. In the CO:H2 system, quality films were obtained for line intensity ratios of H(gamma)/Ar = 4.0, H(gamma)/C2 = 1.1, CH/C2 = 1.9, CO/C2 = 0.73, and O/C2 = 0.89. Nearly identical films were produced in the CH4:O2:H2 system, with line intensity ratios of H(gamma)/Ar = 4:2, H(gamma)/C2 = 1.2, CH/C2 = 1.5, CO/C2 = 0.78, O/C2 = 0.99. These results indicate that feedgas composition is less important than the critical ratios of C/O/H2 in an ECR plasma.

This impedance change can be produced by an electrorheological fluid. The transmission of a known vibration input along a test structure will be correlated to the impedance characteristics of the electrorheological fluid. This impedance characteristic of the fluid will be expressed in terms of the applied electric field. The attenuation characteristics of the electrorheological fluid on longitudinal vibration have been presented through experimental and numerical results. The results of this study showed an attenuation of 4 dB in the transmissibility of acceleration from the forward to the aft ends of the test structure. This level can be increased by using a fluid possessing a lower zero state viscosity. A secondary result of this investigation is understanding the physics of the damping mechanism in the test module when the electric field was increased from 1.2 kV/mm to the value of 1.6 kV/mm. During this increase in the electric field, the logarithmic decrement increased by more than a factor of three. The transmissibility data also shows that the resonant frequency decreased.

The techniques are based on the direct summation of sinusoidal components, with the number of components largely dependent on the spectral bandwidth. At the lower end of bandwidths corresponding to actual ocean waves, only five to 10 components of equal amplitude are sufficient to give values that deviate by only a few percent from theoretical criteria governing random waves. At the upper end of the bandwidth range, 15-20 components at equal frequency intervals are required to give comparable accuracy. Guidelines are given for proper choices of the upper and lower spectral energy (or frequency) cutoffs. Criteria that are not satisfied by these low-order models are identified. The significance of these criteria in actual applications and possible remedies within the framework of the present models are discussed.

We report the use of the 600 nm flash pumped dye laser for the fragile telangiectasia of the elderly in our classification of the Class 2 group. In some vessels studied, the special Teflon-insulated, intravenous electric needle of Kobayashi-Yamada was used. For the bluish vessels, the 600 nm flash pumped dye laser penetrated deeper into the vessel than the 585 nm, but multiple and repeated treatments were needed for clinical effect. Preliminary studies have also shown some initial response in port wine marks and facial telangiectasia. C1 USN HOSP,DEPT DERMATOL,SAN DIEGO,CA 92134.

No gender differences were found in an othogonalized hierarchical solution of the general factor and technical, quantitative, verbal, and spatial factors that would suggest differential problem-solving strategies as a function of spatial ability. However, a small technical factor loading (approximately .10) for Arithmetic Reasoning for both males and females (considered salient when compared to loadings for Mathematics Knowledge and Numerical Operations) suggested environmental or experiential interactions contribute to problem-solving ability. Consistent with these findings, an approximate .10 correlation between the sex variable and Arithmetic Reasoning for a combined group analysis was attributed to the technical factor.

To date, however, almost nothing is known about the link between intelligence and forgetting when subjects are exclusively drawn from the normal ability ranges. In the present study, one hundred and sixteen normal young men were asked to recall problem solutions after performing a distractor task consisting of one, two, or three speeded math items. The results indicate that longer distractor intervals result in diminished recall, but, more importantly, that high and low ability subjects forget at equal rates.

Actual experimental results are described for the Low Atmospheric Control Experiment (LACE) spacecraft. This is a low earth orbit satellite that was launched into a circular orbit. Its structure consists of a central rigid body or bus with three deployable booms. The first boom is the gravity gradient boom while the second is the retro-reflector boom. We accomplished the identification of the structural modes and damping factors of the spacecraft in orbit. A systems approach was used to analyze the experiment and present identification techniques utilizing the frequency characteristics of the Hankel operator. Frequency domain error bounds and time domain error bounds were considered. The experiment was performed on a satellite in conjunction with the Naval Research Laboratory. The experiment utilized ground based laser illumination with Doppler shifted returns and identified three of the lowest vibration modes. The accuracy of the methods was extremely good.

These images show evidence of pronounced interaction between the adjacent lateral dipoles located near the chiral centres of neighbouring molecules. The two dimensional structure at the graphite-liquid crystal interface is found to be highly ordered. Features of this crystal-like order are the pronounced dimer arrangement within a layer and a kinked conformation in which the aromatic core is tilted with respect to the chains. The core axis is tilted at 30-degrees with respect to the layer normal in the plane of the interface. This tilt is very similar to the tilt angle of the bulk material C1 GEOCENTERS INC,10903 INDIAN HEAD HIGHWAY,FT WASHINGTON,MD 20744. USN,RES LAB,CTR BIO MOLEC SCI & ENGN,WASHINGTON,DC 20375.

The 1-picryl-4,6-dinitrobenzimidazoles and their 1-methyl analogs were examined by several NMR techniques in order to confirm their structures, and assignment strategies are discussed. Nuclear Overhauser enhancement (NOE) difference spectroscopy and H-1/C-13 correlation experiments were used to make definitive assignments of the H-1 and C-13 NMR spectra. It was found that both solvent and temperature had significant effects on the chemical shifts of the benzimidazole protons. This was especially true for the 1-picryl derivatives.

Juvenile mussels 5-1O mm in length were fed suspensions of Isochrysis galbana associated with bistributyltin (TBT). The quantity of TBT ingested by mussels was monitored by measuring the clearance of algal cells from experimental aquaria during daily feeding periods. Stress-protein concentrations were determined by two methods: by metabolic labeling with S-35 methionine and by screening Western blots with a commercially available monoclonal antibody found to bind specifically to two mussel proteins of approximately 73 000 and 72 000 MW. Autoradiographs showed the appearance of a 70-kDa protein in conjunction with a linear decline of filtration rates in mussels with accumulated TBT doses of 140 and 750 ng TBT/mm accumulated over 72 h. At a dose of 1450 ng TBT/mm, filtration rates declined to nearly zero, without mortality, and incorporation of S-35 methionine was nearly undetectable. In experiments utilizing immunoblots, comparison of control and TBT-exposed mussels showed a linear increase in approximately 70 000 MW stress-protein (SP70s) concentrations. Mussels exposed to the highest doses had levels more than ten times those of controls. Increases in the SP70 levels corresponded linearly with decreases in mussel filtration rates.

This paper considers a problem in which an enemy attempts to maximize flow through a capacitated network while an interdictor tries to minimize this maximum flow by interdicting (stopping flow on) network arcs using limited resources. This problem is shown to be NP-complete even when the interdiction of an arc requires exactly one unit of resource. New flexible, integer programming models are developed for the problem and its variations and valid inequalities and a reformulation are derived to tighten the LP relaxations of some of these models. A small computational example from the literature illustrates a hybrid (partly directed and partly undirected) model and the usefulness of the valid inequalities and the reformulation.

Comparison of the confirmed positive drug rates for pre-inductees into the Navy during the MEPS program testing period with the confirmed drug-positive rates for 5 years before and 1 year after MEPS testing showed a decrease in the confirmed positive rate for THC-COOH and an apparent initial decrease for cocaine metabolite as a result of MEPS testing. The overall results for cocaine seem to be overshadowed by other demographic factors operating in the population tested.

Naval personnel who exceed standards for %BF can be separated from active duty. Currently, %BF predictions are determined by circumference measurements and a prediction equation (circumference equation = CEQ). In view of the importance these prediction results have for personnel retention, a validation study was undertaken to determine the accuracy of %BF prediction for a population determined to be overfat by the CEQ. The population for the validation study comprised men with 22 %BF or greater and women with 30%BF or greater, Values for %BF were determined for 49 men and 50 women by hydrostatic weighing (HW) and circumference measurements at the Naval Submarine Medical Research Laboratory (NSMRL) using a regression equation developed at the Naval Health Research Center (NHRC), San Diego, California. The HW and CEQ values were compared to a superset of the original NHRC population. The correlation coefficients for the NSMRL validation group were lower than those reported in the original NHRC group. The results are attributed to the restricted range of NSMRL data and greater error of prediction at extreme ranges of values. A medical diagnostic model was used to evaluate the sensitivity, specificity, and predictive value of CEQ. It shows that the Navy's current procedures produce a 6.8 to 18% false positive rate for individuals declared as having excess body fat. The data suggest that caution should be utilized when using the CEQ method for individual career decisions.

An uninterrupted miscibility is observed between the SmO phase of MHTAC and the antiferroelectric SmC phase of MHPOBC indicating thereby that these smectic modifications belong to the same phase type. In addition, the antiferroelectric properties of MHTAC have been studied. Above a threshold electric field the SmO phase is transformed into a ferroelectric switching state which exhibits a maximum spontaneous polarization of about 380 nC/cm2.

Alternative boundary conditions are developed for the scheme so that the changes to the wind at the lateral boundaries of the model are consistent with the changes in the integrated mass divergence and vorticity over the domain. The convergence of the modified scheme is shown to be rapid for two different grids. For a grid with significant topography along the lateral boundaries, use of increased diffusion in the boundary zone is shown to negatively impact the convergence of the scheme. Model integrations are performed to show the effectiveness of the scheme with improved boundary conditions in removing the gravity-wave oscillations. The results are compared with the damping of the gravity waves in the boundary zone by the time-integration scheme and by different lateral boundary treatments. The influence of noisy boundary values is also tested. C1 SCI APPLICAT INT CORP,MCLEAN,VA.

Here a parallel algorithm is developed for the solution of these equations, which is based on Arakawa and Lamb's scheme. It is shown that the efficiency of the scheme on an eight-node INTEL iPSC/2 hypercube is 81%. Forty mesh points in the x direction and 19 in the y direction were used in each subdomain.

A quality loss of zero is perfect quality. Loss functions for four types of specifications are described, two sided, two sided with one side preferable, one sided maximum, and one sided minimum. An example is given of determining the production quantity split between two sources of microwave tubes using the quality rating and the proposed cost. The supplier with the lowest quality loss earns the maximum point amount in the quality category. The other supplier earns quality points which are proportionally reduced by how the supplier's rating compares to the lowest quality loss rating. The same point award method is used for the cost category. The supplier with the highest point total is the preferred supplier. The quality rating can, also, be used to incentivize a sole source supplier. At first glance the method may be criticized for only focusing on the suppliers' output, however, this method will incentivize suppliers to focus on their processes and achieve a lower variation in output. This is a specific tool to help implement the continuous improvement aspect of the Navy's total quality management effort.

Setting accuracy requirements in this manner results in a wide and unpredictable range of false rejection and acceptance probabilities. This causes extra costs due to either: 1) over specification of measurement systems accuracy requirements; 2) time, effort, retesting, and resolution of false rejections; or 3) system degradation caused by false acceptance of out-of-specification parts. Achieving a consistent and known risk of false acceptance is only possible by considering the measured process C(pk), the process's mean in relation to the center of the specification range, and the measurement system error distribution. This paper presents a method for calculating the probabilities of false rejection and false acceptance for a normal process which is measured with, alternately, uniform and normally distributed error. It is shown that under most conditions uniform error causes 20% to 30% higher false rejection and acceptance probabilities. Thus, knowledge of measurement error distribution could provide lower total production cost.

The free-surface dynamics and the mixed-layer features are included in the model. The numerical model incorporates the realistic coastline and bottom topography. The sigma coordinate model has eighteen levels in the vertical and 0.2-degrees x 0.2-degrees horizontal resolution for the entire gulf. The study focuses on nonlinear interaction between hurricane induced currents and the Loop Current. The numerical simulations show that there is a strong nonlinear interaction between the hurricane and the Loop Current in the southern and central parts of the eastern gulf. The surface currents due to nonlinear interaction obtain a maximum of over 1 m s-1 in the southern gulf. The numerical results also show that the hurricane interaction with the Loop Current strongly affects current, mixed-layer depth, and elevation fields. There is a strong current response to Hurricane Camille in the surface layer on the shelf with a peak velocity approximately 2.2 m s-1. There is a definite right hand bias in the mixed-layer depth field with a maximum of about 90 m. C1 UNIV COLORADO,BOULDER,CO 80309.

A thorough review of spectral line intensities implies that plasmas in the different parts of the upper solar atmosphere are transiently ionizing and are consistently associated with increased electron density. A possible mechanism consistent with the observations is a current driven plasma compression. RP FELDMAN, U (reprint author), USN,RES LAB,EO HULBURT CTR SPACE RES,WASHINGTON,DC 20375, USA.

The spectra were emitted from high-density laser-produced plasmas. Plasmas were produced by irradiating thin- and thick-foil targets made of magnesium, aluminum, phosphorus, and chlorine with the OMEGA laser in a line-focus geometry. Line profiles were compared to a Stark-broadening calculation that uses the static-ion approximation and an impact approximation for the electrons. The dependence of Stark broadening on atomic number is discussed.

Samples were prepared at room temperature on mica, glass, and silicon substrates using the dc-magnetron-sputtering method. For films with the same Fe-layer thickness, it was found that the magnetic moment of Fe decreases with increasing thickness ratio of Cu to Fe. For films with a Cu to Fe thickness ratio of 3, it was found that the magnetic moment of Fe decreases with decreasing thickness of the individual Fe layers. XRD and XAFS results revealed that in the multilayered films, Cu has a well-defined fcc structure with minimal amount of structural disorder independent of the individual layer thickness or thickness ratio. On the other hand, quantitative analysis of EXAFS data revealed that the crystal structure of Fe changes with decreasing thickness of the Fe layers from distorted bcc (for 42- and 21-angstrom-thick Fe layers) to fcc (for 10.5- and 6.3-angstrom-thick Fe layers) in films with the Cu layer three times thicker than the Fe layer. The single-phase fcc Fe of the 6.3-angstrom Fe/19-angstrom Cu multilayered film was found to have a lattice constant of 3.596 angstrom and is ferromagnetic with a Curie temperature of 210 K and a spontaneous magnetization of approximately 690 emu/cm3.

Below 50 K the NSR is shown to be caused by low-frequency excitations of disorder modes, which are intrinsic to the glasslike state of beta aluminas. The data can be interpreted consistently in the framework of thermally activated excitations of modes that are represented by asymmetric double-well-potential configurations with suitably chosen densities of states. Further, the observed NSR rates are shown to be related to corresponding ac-conductivity data via the fluctuation-dissipation theorem. C1 USN,RES LAB,WASHINGTON,DC 20375.

Through the use of a supercell geometry, rigid-ion-type approximations are avoided and the full electron-phonon matrix elements are determined from finite differences of the LDA potentials corresponding to frozen-in phonon at GAMMA X, and Z. At the X point, all fully symmetric A(g) modes (i.e., having the symmetry of the oxygen planar-breathing mode) as well as three modes having B3g symmetry are examined. Small linewidths were found for the three B3g modes, and moderate linewidths for the A(g) modes, the largest corresponding to ratios gamma(q, nu)/omega(q, nu) = 0.02 for the oxygen breathing and axial modes. The axial O(z) mode at the Z point has a very large width, gamma(q, nu)/omega(q, nu) = 011. Unusual long-range Madelung-like interactions are found to yield large matrix elements, especially for modes near the zone center and are responsible for couplings of the cations (La) to the charge carriers. The linewidth of a mode also directly determines lambda(q, nu), the contribution of mode (q, nu) to the electron-phonon coupling constant, lambda, and an approximate average over the Brillouin zone yields lambda congruent-to 1.3, about the magnitude necessary to explain T(c) in La2-xMxCuO4. In spite of some very strong coupling to low-frequency modes, the mean frequency omega(log) that is important in determining T(c) is large: omega(log) = 321 cm-1 = 462 K. The calculated large electron-phonon coupling arises from a combination of weak screening and unusual nonlocal Madelung-like interactions, in concert with strong Cu-O hybridization that results in good metallic behavior within the planes. These features are common to all of the layered cuprates, indicating that the entire class should show strong electron-phonon coupling. C1 USN,RES LAB,COMPLEX SYST THEORY BRANCH,WASHINGTON,DC 20375.

A lambda-like anomaly is observed, indicative of an exceptionally short T = 0 Ginzburg-Landau coherence length in this material. If the fluctuations are assumed to be Gaussian corrections to mean-field-behavior, the data are best described by three-dimensional fluctuations of a two-component order parameter, with the underlying BCS step indicating strong-coupling behavior. However, a more complicated order parameter or a logarithmic (critical) divergence cannot be ruled out on statistical grounds. Application of a magnetic field B broadens the transition and reduces the amplitude of the anomaly with little or no apparent shift in the onset of superconductivity; the effects are more pronounced for B parallel to the c axis than for B in the ab plane. These results are not consistent with mean-field theory, but may be understood in the context of critical finite-size scaling. This approach exploits the well-known dimensional reduction for superconductors in a magnetic field. C1 UNIV ILLINOIS,DEPT PHYS,URBANA,IL 61801. UNIV ILLINOIS,MAT RES LAB,URBANA,IL 61801.

Results from this approach are shown to be in agreement with the usual solvability condition for the case of exact resonance. Away from resonance, the results are in agreement with a direct solution of the nonhomogeneous system. This approach also provides accurate results for the case of near resonance, in contrast to the approach currently in widespread use. Following this alternative approach, the Landau constants can be calculated accurately in a straightforward manner without requiring the solvability condition in some arbitrary neighborhood of resonance.

A pinch-reflex ion diode on the NRL Gamble II accelerator focuses a proton beam onto the entrance aperture of a 2.5 cm diam, 1.2 m long z-discharge transport system. The beam ions are charge and current neutralized in the discharge plasma, and execute betatronlike orbits in the magnetic field of the discharge. Ion beam diagnostics include shadowbox imaging and prompt-gamma radiation measurements from LiF targets. Under appropriate conditions, 95% particle transport and 90% energy transport are observed, with the only energy loss attributed to classical stopping in the channel gas. The transverse phase-space distribution of the beam measured by the shadowbox is consistent with full charge and current neutralization of the transported beam. C1 JAYCOR,VIENNA,VA 22182.

A closed integrodifferential equation for the beam current is obtained, assuming that the beam current is a function of time t and propagation distance z. Properties of the current and energy modulation are investigated from this integrodifferential equation for a broad range of system parameters. Magnitudes of the energy and current modulation are determined in terms of the gap voltage, the cavity frequency, geometric configuration, the beam intensity, and initial kinetic energy of the beam. The modulation amplitude increases, reaches peak, and decreases slowly, as the beam propagates through the amplifier. A simple expression of scaling law for maximum current modulation is obtained. This scaling law could be useful in the design and fabrication of a high-performance klystron. Nonlinear mode evolution in current profile is also investigated by Fourier decomposing the current modulation obtained from the integrodifferential equation. The mode evolution in a long-range propagation of an electron beam exhibits various interesting physical properties. For example, the maximum amplitude of the fundamental mode (l = 1) occurs at the propagation distance, where all other modes vanish or have a very small amplitude. This property ensures a monochromatic frequency. RP UHM, HS (reprint author), USN,CTR SURFACE WARFARE,10901 NEW HAMPSHIRE AVE,SILVER SPRING,MD 20903, USA.

Such mixing within the crystalline phase is usually associated with chain isomorphism, whereby structurally similar blend components cocrystallize. In the present case, the amorphous PVE is literally entrapped as a defect in the crystal. This is in addition to its interlamellar entrapment observed in an earlier study.

Spray forming has proved to be a viable and cost effective alternative to conventional metalworking technology for the production of material preforms with properties surpassing those of their cast and wrought counterparts. Current programmes at Carderock Division are aimed at optimisation of the process, certification of the spray formed products, and industrialisation of the technology.
