PYRENE; DNA
AB Dibenzo[a,l]pyrene (DB[a,l]P) is the most potent carcinogen known among aromatic hydrocarbons. DB[a,l]P-11,12-dihydrodiol, precursor to the bay-region diol epoxide, is slightly less carcinogenic than the parent compound. DB[a,l]P and its 11,12-dihydrodiol were covalently bound to DNA by cytochrome P-450 in 3-methylcholanthrene-induced rat liver microsomes, and DB[a,l]P was also bound to DNA by horseradish peroxidase. The ''stable'' (remaining intact in DN4 under normal conditions of purification) and ''depurinating'' (released from DNA by cleavage of the glycosidic link between the purine base and deoxyribose) adducts were identified and quantified. Stable adducts were analyzed by the P-32-postlabeling technique. Depurinating adducts were identified by comparison of their retention times with those of standard adducts on HPLC in two solvent systems. Confirmation of their identity was obtained by means of fluorescence line-narrowing spectroscopy. When DB[a,l] was activated by horseradish peroxidase, the depurinating adducts 3-(DB[a,l]P-10-yl)adenine (DB[a,l]P-10-N3Ade, 33%), 7-(DB[a,l]P-10-yl)adenine (DB[a,l]P-10-N7Ade, 27%), and 7-DB[a,l]P-10-yl)guanine (DB[a,l]P-10-N7Gua, 5%) were formed. Unidentified stable adducts comprised the remaining 35% of the detected adducts. When DB[a,l]P was activated by microsomes, the one-electron oxidation depurinating adducts DB[a,l]P-10-N3Ade (28%), DB[a,l]P-10-N7Ade (14%), DB[a,l]P-10-N7Gua (2%), and DB[a,l]P-10-C8Gua (6%), as well as the diol epoxide depurinating adducts (+/-)-syn-DB[a,l]P-diol epoxide (DE)-14-N7Ade (31%) and (+/-)-anti-DB[a,l]PDE-14-N7Gua (3%), were formed. Stable adducts predominantly formed via the DB[a,l]PDE pathway represented 16% of the adducts detected. When DB[a,l]P-11,12-dihydrodiol was activated by microsomes, the same two depurinating adducts arising from DB[a,l]PDE were found, but they constituted only 19% of the adducts because the amount of stable adducts was much higher than with DB[a,l]P. Analysis of stable DNA adducts by the P-32-postlabeling method indicates that the profiles formed from DB[a,l]P and its 11,12-dihydrodiol were qualitatively similar. These results demonstrate that the major depurinating adducts formed by both DB[a,l]P and its 11,12-dihydrodiol are at the N-3 and N-7 of adenine, resulting in apurinic sites in the DNA.

AB A 64-kDa protein was purified from an octyl glucoside/cholate extract of spinach thylakoids. N-Terminal analysis yielded 23 residues of sequence, of which the first 15 were identical to a sequence reported [Gal, A., Hermann, R. G., Lottspeich, F., & Ohad, I. (1999) FEES Lett. 298,; 33-35] for a protein kinase with specificity toward the photosystem II light-harvesting complex (LHC-P). We report the complete sequence of this 64-kDa protein, deduced from cDNA clones. The transit peptide has a chloroplast import signal at the N-terminus and a C-terminal hydrophobic span bounded by basic amino acids that predicts localization of the protein to the thylakoid lumen. The mature protein sequence is about 50% identical to several polyphenol oxidases (PPOs). Canonical protein kinase motifs are absent, as are sequences characteristic of ATP-binding sites. The mature protein resembles arthropodan hemocyanin (Hc), possessing three major domains. The N-terminal domain is rich in cysteine residues and predicted alpha-helices. The central domain has a conserved motif, N-terminal to a presumptive Cu-A site; that is not found in tyrosinases or Hc and is proposed as the provider of a third imidazole ligand to Cu-A. An unusual 13-residue, glutamine-rich link begins a C-terminal domain containing 7 predicted beta-strands which, by analogy with Hc, may form an antiparallel beta-barrel. We conclude that this 64-kDa polypeptide is a lumenal PPO and the precursor of a 42.5-kDa PPO form described previously [Golbeck, J. H., & Cammarata, K. V. (1981) Plant Physiol. 67, 977-984]. In view of its lumenal location and primary sequence, it is unlikely to be a serine/threonine protein kinase.

AB A tritium labeled Manduca sexta adipokinetic hormone (M-AKH) was synthesized (pE-L-T-[p(3)H]F-T-S-S-W-G-NH2) (specific activity 27 Ci/mmol) which was fully active in a bioassay. It was used in a filtration based binding assay to characterize the M-AKH receptor from the fat body of M. sexta. Membrane fractions were prepared from fat body and optimal binding conditions were determined. A K-d of 7 . 10(-10) M was determined and the receptor concentration estimated to be 0.5 pmol/mg membrane protein. No receptor binding was found when membranes were prepared from brain, heart or Right muscle of M. sexta or from fat body of the cockroach Blaberus discoidalis. However, specific binding was found with membrane preparations from the pterothoracic ganglion of M. sexta. The membranes from the ganglion had a much smaller number of binding sites than the fat body membranes, however, the binding was specific and observed in each experiment.

ID TRANSPORT; PLASMA
AB Previous representations of toroidal eigenmodes in the presence of shear flows are pointed out to give rise to a secular time behaviour for perturbations with sufficiently small perpendicular wavelengths. The purpose of this paper is to present an extended ballooning representation, properly accounting for the effects of strong toroidal rotation as well as of differential rotation and correcting such a deficiency. The basic feature of the perturbation is that it exactly satisfies all the dynamical constraints and, in particular, it is periodic in time with a global period (i.e., independent of position).

TI A NEW MODEL TO DETERMINE DYNAMIC SURFACE-TENSION AND ELONGATIONAL
VISCOSITY USING OSCILLATING JET MEASUREMENTS
SO JOURNAL OF FLUID MECHANICS
LA English
DT Article
ID AIR WATER INTERFACE; ADSORPTION-KINETICS; DROPS; BREAKUP
AB We present an integro-differential equation model which, combined with experimental measurements of an oscillating free surface jet, calculates dynamic surface tension and elongational viscosity of a fluid. Our model builds upon previous models due to Rayleigh and Bohr in that it self-consistently incorporates the effects of viscosity and gravity. Further, surface tension and viscosity are allowed to be non-constant. The principal result of this paper is a technique for the measurement of surface tension of newly forming surfaces on the millisecond timescale relevant for agricultural spray mixtures. Coincidentally, our model independently yields the elongational viscosity of the fluid, although our present experimental apparatus limits the accuracy of measurement of this material property.
In this paper we take measurements from physical jet experiments and implement our inverse model to deduce these material properties. The model is first benchmarked against standard techniques on a well-characterized fluid with constant surface tension and Newtonian viscosity. We then apply our method to an agricultural spray mixture, with non-constant surface tension and non-Newtonian theology. We measure (i) the rapid decay of surface tension from the newly formed surface (aged less than a millisecond) to the much lower equilibrium value, and (ii) the rate dependence of elongational viscosity.

AB The human genome contains multiple copies of sequences related to the HERV-K family of endogenous retroviruses, homologous to the B-type mouse mammary tumour virus. A DNA fragment closely resembling an HERV-K long tandem repeat (LTR) was detected in a library of hncDNA clones enriched for sequences from human chromosome 19. Sites showing homology to the sequence of this fragment have been identified on human chromosome 19 by hybridization to previously mapped chromosome 19 cosmids. Thus the distribution of LTR sequences on a specific human chromosome has been mapped for the first time. We estimate the total number of such sites on human chromosome 19 to be at least 110. Many of these sites are located in the vicinity of known genes. The precise localizations (to specific cosmids) of LTR-homologous sequences on chromosome 19 can serve as a reference source and will automatically provide further insight into LTR-gene relationships as new genes are mapped onto the chromosome.

AB The zinc contents of fragments of Escherichia coli glutamyl-tRNA synthetase, as well as the conservation of the CYC sequence only in zinc-containing glutamyl-tRNA synthetases, suggested that the (98)CYCX(24),,CRHSHEHHADDEPC(138) includes some or all residues involved in binding its zinc atom (Liu, J., Lin, S.-X., Blochet, J.-E., Pezolet, M., and Lapointe, J. (1993) Biochemistry 32, 11390-11396). Extended x-ray absorption fine structure (EXAFS) shows that this zinc atom has a four-coordinate non-planar coordination environment with 3 sulfur and 1 nitrogen atoms with bond lengths, respectively, 2.37 +/- 0.02 Angstrom and 2.01 +/- 0.02 Angstrom, presumably belonging to and cysteine residues and 1 histidine residue. Conservative replacement of each histidine and cysteine residue of the C-98-C-138 segment, respectively, with glutamine (Q) and serine (S), yields variants H129Q, H131Q, H132Q, and C138S (which sustain the growth at 42 degrees C of E. coli JP1449, whose glutamyl-tRNA synthetase is thermosensitive) and C98S, C100S, C125S, and H127Q (which do not). The amount of this enzyme in these mutants is at least 1 order of magnitude larger than that in a wild type strain; however, no glutamyl-tRNA synthetase activity is detectable in extracts of the variants C100S and C125S, whereas its specific activity in those of C98S and H127Q is about 10-fold lower than in cells overproducing the wild type enzyme or the variants H129Q, H131Q, H132Q, and C138S. These results indicate that the zinc atom present in E. coli glutamyl-tRNA synthetase is bound by the 2 evolutionarily conserved cysteines at positions 98 and 100, and by Cys(125) and His(127). Molecular modeling of the N-terminal half of this enzyme, using the known structure of E. coli glutaminyl-tRNA synthetase, supports this conclusion and suggests that the C-98-H-127 segment does not have the characteristics of the classical zinc fingers.

AB Monoclonal human light chains, i.e. Pence Jones proteins, and their recombinant variable fragments (V-L) were screened for proteolytic activity using peptide-methylcoumarinamide (peptide-MCA) conjugates and vasoactive intestinal polypeptide (VIP) as substrates. Sixteen of 21 Pence Jones proteins and one of three V-L fragments were capable of detectable cleavage of one or more substrates. The magnitude and kinetic characteristics of the activity varied with different substrates. Among the peptide-MCA substrates, the presence of tripeptide or tetrapeptide moieties with a basic residue at the scissile bond generally favored expression of the activity. The influence of N-terminal flanking residue recognition was evident from differing values of K-m and k(cat) (turnover number) observed using different Arg-containing peptide-MCA substrates. Different light chains displayed different kinetic parameters for the same substrate, suggesting unique catalytic sites. Hydrolysis of VIP was characterized by nanomolar Michaelis-Menten constants (K-m), suggesting comparatively high affinity recognition of this peptide, The 25-kDa monomer and the 50-kDa dimer forms of one light chain preparation were resolved by gel filtration in 6 M guanidine hydrochloride, Following renaturation, the monomer displayed 51-fold greater peptide-MCA-hydrolyzing activity than the dimer. A renatured V-L domain prepared by gel filtration in 6 M guanidine hydrochloride displayed VIP-hydrolyzing activity in the 12.5-kDa peak fractions. These results provide evidence for the proteolytic activity of certain human light chains and imply that this phenomenon may have a pathophysiological significance.

AB A method that combines thin film deposition and physical masking techniques has been used for the parallel synthesis of spatially addressable libraries of solid-state materials. Arrays containing different combinations, stoichiometries, and deposition sequences of BaCO3, Bi2O3, CaO, CuO, PbO, SrCO3, and Y2O3 were generated with a series of binary masks. The arrays were sintered and BiSrCaCuO and YBaCuO superconducting films were identified. Samples as small as 200 micrometers by 200 micrometers in size were generated, corresponding to library densities of 10,000 sites per square inch. The ability to generate and screen combinatorial libraries of solid-state compounds, when coupled with theory and empirical observations, may significantly increase the rate at which novel electronic, magnetic, and optical materials are discovered and theoretical predictions tested.

AB We report on the preparation of quantum-sized CdS particles capped with three bifunctional mercaptocarboxylic acids (HS-(CH2)(n)-CO2H, n = 1-3). The absorption spectra of all three colloid preparations exhibit a new band at 365 nm, assigned to a charge transfer to particle transition, probably f;om the free carboxylate head - group. Among these, mercaptobutyric acid was the most efficient acid at controlling the size of the CdS particles. TiO2 particles were attached to the CdS particles through the carboxylic end of the bifunctional caps. Bridging TiO2 to CdS through these acids leads to quenching of the blue and,enhancement of the red edges of the emission spectra of CdS. This is attributed to selective electron transfer from shallow traps, but not from deeper-traps, to the TiO2 particle. The efficiency of the quenching decreases upon increasing the alkyl chain length of the acid Presumably because of the distance dependence of the electron transfer process.

AB Structural changes accompanying the reduction of (mu-oxo)bis[(meso-tetrakis(methoxyphenyl)porphyrinato)-iron], [Fe(TMPP)]O-2, irreversibly adsorbed on Black Pearls 2000 (BP) high area carbon in aqueous electrolytes have been examined in situ by X-ray absorption fine structure (XAFS). In the pH range 5-10.8, the average iron-to-porphinato nitrogen distance, d(Fe-N-p), for the ferric species, using theoretical phases and amplitudes calculated from FEFF 3.28 (2.09 +/- 0.01 Angstrom), was found to be, within experimental error, the same as that reported for the closely related [Fe(TPP)]O-2 in crystalline form (2.087 Angstrom). At extreme pH values d(Fe-N-p) was smaller (2.04 +/- 0.02 Angstrom for pH 1.2 and 3.1 and 2.05; +/- 0.02 Angstrom for pH = 13) than those observed in the intermediate PH range. The values in strong acid are consistent with those reported for the diaquo axially coordinated complex [Fe(TPP)(OH2)(2)](+) (d(Fe-N-p) = 2.045 +/- 0.005 Angstrom), whereas that at pH 13, d(Fe-N-p) = 2.05 +/- 0.02, strongly suggests an axially coordinated dihydroxy complex as the predominant species. :The latter assignment is in agreement with information derived from other Spectroscopic methods for closely related ferric porphyrins in solution phase. In contrast, the corresponding ferrous counterparts displayed values for d(Fe-N-p) (2.02 +/- 0.02 Angstrom) consistent with the iron center placed in the plane of the ring throughout the whole range of pH values. Insight into the possible axial ligation of the ferrous derivatives was: obtained from the dependence of the potential associated with the voltammetric peaks on the solution PH. Spin-state/ stereochemical relationships derived from X-ray crystallography and magnetic measurements of well-characterized iron porphyrins indicate that the adsorbed ferric species are all high spin, whereas the ferrous counterparts are either high or intermediate spin.

AB Total and differential cross sections for the process e(+)e(-) --> gamma gamma(gamma), and the total cross section for the process e(+)e(-) --> gamma gamma gamma, are measured at energies around 91 GeV using the data collected with the L3 detector from 1991 to 1993. We set lower limits, at 95% CL, on a contact interaction energy scale parameter Lambda > 602 GeV, on the mass of an excited electron m(c)* > 146 GeV and on the QED cut-off parameters Lambda(+) > 149 GeV and Lambda(-) > 143 GeV. Upper limits are also set on the branching fractions of Z decaying into gamma gamma, pi degrees gamma and eta gamma of 5.2 x 10(-5), 5.2 x 10(-5) and 7.6 x 10(-5) respectively. The reactions e(+)e(-) --> rho(+)rho(-)n gamma (rho = e, mu, tau) are studied using the data collected from 1990 to 1994. The data are consistent with the QED expectations.

AB We present evidence for soft gluon interference, as required by QCD. This interference is expected to manifest itself in an angular ordering of the gluons radiated within a jet. Using hadronic decays of the Z boson in the L3 detector at LEP, we compare variables sensitive to such an angular ordering, namely the energy-energy correlation asymmetry and the newly introduced particle-particle correlation asymmetry, with the predictions of various parton shower models. Only those models which incorporate the expected interference agree with the data.

AB Addition of 0.5 equiv of water in tetrahydrofuran to Cp(3)Ti in tetrahydrofuran yields the known bridging oxo derivative of Ti(III), (Cp(2)Ti)(2)(mu-O), in high yield. Use of labeled water gives (Cp(2)Ti)(2)(mu-O-18). The EPR spectrum of a toluene glass at 2 K gives a spectrum due to a triplet ground state with g(parallel to) = 1.979, g(perpendicular to) = 1.981, and \D\ = 0.0249 cm(-1). The variable-temperature magnetic susceptibility above 20 K shows intramolecular ferromagnetic coupling and weak intermolecular ferromagnetic coupling; the intramolecular coupling constant is 8.3 cm(-1). Below 20 K, the susceptibility is field dependent. An orbital diagram is presented which accounts for the magnetic behavior in this d(1)d(1) dinuclear metallocene.

AB The line phases in the title are obtained in high yields after fusion of the elements in stoichiometric proportions in Ta containers followed by slow cooling or annealing. The structures were established by single-crystal X-ray means [Na(4)A(6)Tl(13), A = K, Rb, Cs: Im(3) over bar, Z = 2, a 11.5075(7) Angstrom, 11.6648(5) Angstrom, 11.8332(4) Angstrom, R(w)(F) = 2.9, 4.9, 4.2%, respectively; Na3K8Tl13: R(3) over barm$, Z = 3, a 11.0890(6) Angstrom, c = 23.154(2) Angstrom, R(w) = 4.9%]. The structure of cubic Na4K6Tl13 is practically identical with that reported for NaK9Tl13, a composition that cannot be achieved in this structure. The two structure types contain isolated, centered icosahedra of Tl-13(10-) (T-h) and Tl-13(11-)(D-3d) in bcc and ccp arrangements, respectively. All cations bridge between cluster faces or vertices, and their mixed sizes appear critical to the formation of the two structures containing these clusters; which do not occur in the binary systems. The phases exhibit Curie-Weiss (1.7, 1.9 mu(B)) (cubic Rb, Cs) and temperature-independent (chi(M) similar to 1.9 x 10(-3) emu/mol) (rhombohedral K) paramagnetism and poor metal-like resistivities (rho(293) = 310, 625, 69 mu Omega cm), respectively. The novel one-electron-deficient Tl-13(10-) is a result of cation packing limitations, while Tl-13(11-) fulfills (Wade's rule) predictions for a centered icosahedron. Centering of the clusters by thallium contributes markedly to the bonding in both. Theoretical calculations at the extended Huckel and relativistic Huckel (REX) levels for the clusters and at the LMTO (self-consistent band) level for Na4Rb6Tl13 are all consistent with the experimental finding. Mixing of 6p(1/2) and 6p(3/2) levels in the clusters reduces relativistic separations substantially (to similar to 0.2 eV) relative to that in the free Tl atom. Electron localization within the clusters appears dominant.

AB The evaluation of cleaning processes can be performed in real time using the quartz resonator (QR) cleaning monitor as an in situ probe to monitor surface contamination. Viscous properties of thin films are modeled to determine the QR's limitation to film thickness in contact with liquids of varying properties. The demonstrated ability to provide submonolayer mass detection during a cleaning process allows this monitor to be used to probe the kinetics and effectiveness of a cleaning process. This capability can rapidly evaluate the total effectiveness of environmentally friendly alternative cleaning processes needed to replace cleaners such as chlorofluorocarbons (CFCs) and chlorinated hydrocarbons. These monitors could also be used to verify cleaning bath integrity so that bath cleaning solution changes are optimized. This condition would maintain high product quality and yield while minimizing waste from disposal.

We present and discuss our experiments on the applications of our recently developed technique of single-molecule detection to the analysis of molecules of biological interest. These newly developed methods are capable of detecting and identifying biomolecules at the single-molecule level of sensitivity. In one case, identification is based on measuring fluorescence brightness from single molecules. In another, molecules are classified by determining their electrophoretic velocities.

AB Highly sensitive detection of neutral Kr atoms was accomplished by the use of laser-induced fluorescence. In one experiment, Kr at 40 parts per 10(12) in He was detected at a signal-to-noise ratio of 500 by time-resolved fluorescence measurements. The Kr metastable Iss level was populated by cascade after two-photon excitation to the 2p(6) level by the frequency-tripled output of a pulsed single-longitudinal-mode dye laser. After a delay, when scattered laser light and cascade resonance fluorescence became negligible, trace quantities of Kr were detected by the use of a pulsed-laser pumping scheme. In a related experiment, Kr-78/Kr-86 isotope ratios ranging from 1 to 0.1 were measured with a resonant isotopic depletion technique first proposed by Makarov [Sov. J. Quantum Electron. 13, 722 (1983)]. The Kr-86 metastable population was selectively depleted by optical pumping to a higher-lying state that relaxed to the ground state by means of radiative cascade. After the Kr-78/Kr-86 ratio of metastables had been enriched by a factor of 10, the Kr-78 population was probed by pulsed excitation. Premixed Kr-78/Kr-86 ratios were measured to within an accuracy of 10%, even for unresolved, Doppler-broadened transitions.

AB Long, open-path, outdoor interferometric measurement of the index of refraction as a function of wavelength (spectral refractivity) requires a number of innovations. These include active compensation for vibration and turbulence. The use of electronic compensation produces an electronic signal that is ideal for extracting data. This allows the appropriate interpretation of those data and the systematic and fast scanning of the spectrum by the use of bandwidths that are intermediate between lasers (narrow bandwidth) and white light (broad bandwidth). An Environmental Interferometer that incorporates these features should be extremely valuable in both pollutant detection and pollutant identification. Spectral refractivity measurements complement the information available from spectral absorption instruments (e.g., a Fourier-transform infrared spectrometer). The Environmental Interferometer currently uses an electronic compensating device with a 1-kHz response time, and therefore rapid spectral scans are feasible so that it is possible to monitor the time evolution of pollutant events.

AB The degenerate four-wave-mixing spectral profile of the R(1)(9) transition in the A (2) Sigma(+) --> X2 Pi(0, 0) band of OH has been measured for various combinations of saturating pump beams. With increasing pump-beam intensity the degenerate four-wave-mixing line shape changes dramatically near line center. In phase-conjugate geometry, three distinct spectral line shapes were observed for the cases of (1) equally intense pump beams, (2) a strong forward pump and a weak backward pump, and (3) a weak forward pump and an intense backward pump. A significant saturation dip appears in the spectrum near line center for case (3). The measured spectra have been modeled by the use of nonperturbative numerical solutions of the density matrix equations, and agreement between the calculations and the experimental results is excellent. The differences in the saturated line shapes for cases (2) and(3) are explored theoretically, and the calculated results are compared with previous theoretical work [Bloch and Ducloy, J. Opt. Sec. Am. 73, 635 (1985)] in which the line shapes were calculated in the limit of infinite Doppler broadening.

AB A krypton fluoride (KrF) excimer-pumped, nitrogen Raman shifter has been studied for use in a wavelength-optimized solar-blind Raman lidar. First Stokes conversion efficiencies (248 --> 263 nm) as high as 12% have been observed in N-2:He gas mixtures. Both oscillator-amplifier and self-seeded configurations were investigated. Wavelength-dependent effects were investigated with a Nd:YAG laser operating at 532 and 266 nm. A comparison of KrF- and Nd:YAG-pumped Raman shifting has shown that the beam quality of the excimer laser was a major factor in limiting the maximum first Stokes conversion efficiency.

AB Target-of-opportunity observations of the dwarf nova SS Cygni were made by the Extreme Ultraviolet Explorer (EUVE) satellite between 1993 August 17.1 and 23.6 UT (MJD 9216.6 and 9223.1). The observations cover the rise and plateau phases of an anomalous outburst which began on August 15.5 and which reached maximum at V similar to 8.3 on August 20.5. During the observations, the brightness of the source as measured by the Deep Survey instrument rose from similar to 0.015 counts s(-1) to similar to 5 counts s(-1). A delay of similar to 3 days was initially observed between the EUV and optical light curves, but this delay decreased to zero as the light curves approached maximum.
During the interval August 17.3 to 23.6 UT, the 72-130 Angstrom flux as measured by the Short Wavelength Spectrometer rose from similar to 6 x 10(-13) to similar to 6.7 x 10(-11) ergs cm(-2) s(-1), while the 72-90 Angstrom to 90-130 Angstrom count ratio remained constant at 1.39 +/- 0.05. Parameterizing the EUV spectrum with a blackbody absorbed by a column of cold neutral material, we derive the luminosity L(bl) and fractional emitting area f = L(bl)/4 pi R(wd)(2) sigma T-4 of the boundary layer as a function of temperature kT. For kT = 30 eV, N-H similar to 4.4 x 10(19) cm(-2), L(bl) similar to 5 x 10(32) ergs s(-1) and f similar to 1 x 10(-4). For kT = 20 eV, N-H similar to 7.0 x 10(19) cm(-2), L(bl) similar to 2 x 10(33) ergs s(-1), and f similar to 3 x 10(-3). The optical through far-UV luminosity of the accretion disk in outburst is L(disk) similar to 3 x 10(34) ergs s(-1). Therefore, while simple theory predicts that the luminosities of the boundary layer and accretion disk should be comparable unless the white dwarf is rotating very rapidly, zeta = L(bl)/L(disk) similar to 1, we find that zeta less than or similar to 0.07. The most interesting and enigmatic aspect of these observations is the EUV spectrum, which evolved homologously over roughly two orders of magnitude in luminosity. The constancy of the EUV spectrum over such a wide range of brightness seems impossible to reconcile with the standard picture of boundary layer emission.

ID OXYGEN; COEFFICIENTS; SI(111); PLANE
AB We have used the STM to study surface diffusion from the time dependence of the tunneling current. Results were obtained for the power spectrum, W(f), of oxygen adsorbed on stepped Si(111). The measured W(f) for clean Si(111) shows no temperature dependence and it is smaller by at least two orders of magnitude than the spectrum for oxygen-covered Si(111) which broadens with temperature. W(f) can be fitted to the expected theoretical form for a single-diffusion process and thus rules out simultaneous diffusion on the surface and on the tip. We have extracted an activation energy of E(a) = (0.92 +/- 0.15) eV which is lower than expected for such strongly bound system, possibly because of inhomogeneity in the binding sites.

ID TEMPERATURE; PROFILE; AEROSOL
AB During the past several years, several authors have published results of the annual and seasonal trends depicted in the total ozone data from both satellite and ground-based observations. The examination of the vertical profile data available from the balloon ozonesonde and Umkehr observations, however, has been generally restricted to limited periods and to nonseasonal trend calculations. Within this study, we have examined the nonseasonal and the seasonal trend behavior of the ozone profile data from both ozonesonde and Umkehr measurements in a consistent manner, covering the same extended time period, 1968-1991, thus providing the first overall comparison of results. Our results reaffirm the observation of significant negative ozone trends in both the lower stratosphere (15-20 km), about -6% per decade, and upper stratosphere (35-50 km), about -6% per decade, separated by a nodal point in the region of 25-30 km. The upper stratosphere decrease is, apparently, associated with the classic gas phase chemical effect of the chlorofluorocarbons, whereas the cause of the lower stratospheric decline is still under investigation, but may well be associated with the chlorine and bromine chemistry in this region.

AB Ozone measurements taken between 0.90 and 2.5 km above the surface and extending over an 800-km radius from Halifax, Nova Scotia, are presented from aircraft flights between August 21 and September 14, 1992. The mean ozone mixing ratio was found generally to be greater above the top of the mixed layer than near the sea surface. Eleven of the 32 vertical profiles displayed an abrupt transition at the top of the boundary layer, with surface ozone mixing ratios having values of approximate to 15-20 ppb and values above the boundary layer increasing to approximate to 50-60 ppb. This transition between low and high mixing ratios was observed to occur over a vertical scale of less than 0.5 km in soundings taken within 4 hours of each other over horizontal distances of the order of several hundred kilometers. There was a well-mixed boundary layer in all cases where these sudden transitions in the ozone profiles were observed. These profiles are associated with subsidence over land, followed by dry deposition within a hydrocarbon-poor, well-mixed continental boundary layer. Ozone loss through surface deposition exceeded ozone production by the time the air masses arrived at the maritime coastal waters. Two other broad categories of profiles are described, the most common having the ozone mixing ratio increasing linearly with height to the top of the sampling domain at 2.5 km. A third category had only a local maximum in ozone with much smaller values higher and lower in the atmosphere.

The original purpose of these experiments was to obtain the absolute instrumental efficiency for our time-of-flight mass spectrometer. We have discovered, as a by-product, that useful information about the absolute cross section for neutral dissociation can also be obtained from such studies.

AB Benzene is a ubitiquous human environmental carcinogen, One of the major metabolites is hydroquinone, which is oxidized in vivo to give p-benzoquinone (p-BQ), Both metabolites are toxic to human cells, B-BQ reacts with DNA to form benzetheno adducts with deoxycytidine, deoxyadenosine, and deoxyguanosine. In this study we have synthesized the exocyclic compounds 3-hydroxy-3,N-4-benzetheno-2'-deoxycytidine (p-BQ-dCyd) and 9-hydroxy-1,N-6-benzetheno-2'-deoxyadenosine (p-BQ-dAdo), respectively, by reacting deoxycytidine and deoxyadenosine with p-BQ. These were converted to the phosphoamidites, which were then used to prepare site-specific oligonucleotides with either the p-BQ-dCyd or p-BQ-dAdo adduct (pbqC or pbqA in sequences) at two different defined positions, These oligonucleotides were efficiently nicked 5' to the adduct by partially purified HeLa cell extracts-the pbqC-containing oligomer more rapidly than the pbqA-containing oligomer, In contrast to the enzyme binding to derivatives produced by the vinyl chloride metabolite chloroacetaldehyde, the oligonucleotides up to 60-mer containing p-BQ adducts did not bind measurably to the same enzyme preparation in a gel retardation assay, Furthermore, there was no competition for the binding observed between oligonucleotides containing 1,N-6-etheno A deoxyadenosine (1,N-6-etheno-dAdo; epsilon A in sequences) and these oligomers containing either of the p-BQ adducts, even at 120-fold excess, When highly purified fast protein liquid chromatography (FPLC) enzyme fractions were obtained, there appeared to be two closely eluting nicking activities. One of these enzymes bound and cleaved the EA-containing deoxyoligonucleotide. The other enzyme cleaved the pbqA- and pbqC-containing deoxyolrgonucleotides. One additional unexpected fact was that bulk p-BQ-treated salmon sperm DNA did compete effectively with the epsilon A-containing oligonucleotide for protein binding, This raises the possibility that such DNA contains other, as-yet-uncharacterized adducts that are recognized by the same enzyme that recognizes the etheno adducts, In summary, we describe a previously undescribed human DNA repair activity, possibly a glycosylase, that excises from DNA pbqC and pbqA, exocyclic adducts resulting from reaction of deoxycytidine and deoxyadenosine with the benzene metabolite, p-BQ. This glycosylase activity is not identical to the one previously reported from this laboratory as excising the Pour etheno bases from DNA.

With this motivation, we examine the consequences of the change in effective radiative recombination reaction rate coefficients produced by intense stimulated emission. The proton-electron recombination is considered as a natural laser, leading to the Formation of spatially nonuniform distributions of neutral matter earlier than the recombination epoch.

AB Given a specific physical mechanism for instabilities during cosmological recombination discussed in an earlier paper, we examine the nonlinear growth of density structures to form fractal-like structural patterns out to the horizon scale at that epoch (similar to 200 Mpc today), A model for such fractal patterns is presented. Such effects could explain observed large-scale structure patterns and the formation of objects at high z, while keeping microwave background anisotropies at the observed minimal levels. We also discuss possible microwave background implications of such a transition and note a potentially observable spectral signature at lambda similar to 0.18 mm as well as a weak line near the peak in the microwave background.

AB Knowing how motile bacteria move near and along a solid surface is crucial to understanding such diverse phenomena as the migration of infectious bacteria along a catheter, biofilm growth, and the movement of bacteria through the pore spaces of saturated soil, a critical step in the in situ bioremediation of contaminated aquifers, In this study, a tracking microscope is used to record the three dimensional motion of Escherichia coli near a planar glass surface, Data from the tracking microscope are analyzed to quantify the effects of bacteria-surface interactions on the swimming behavior of bacteria, The speed of cells approaching the surface is found to decrease in agreement with the mathematical model of Ramia et al, [Ramia, M., Tullock, D. L, & Phan-Tien, N. (1993) Biophys J. 65,755-778], which represents the bacteria as spheres with a single polar flagellum rotating at a constant rate, The tendency of cells to swim adjacent to the surface is shown in computer-generated reproductions of cell traces, The attractive interaction potential between the cells and the solid surface is offered as one of several possible explanations for this tendency.

DE INDIUM; SURFACE TENSION; URANIUM
AB The sessile-drop method is used to measure the surface tension and density of liquid indium and uranium under high vacuum. Measurements are made over the temperature range 156-500 degrees C for In and at the melting point for U. Surface oxides are efficiently removed with a glow discharge system. Drop profiles are captured by photograph and processed using nonlinear regression to yield the surface tension and density. In this regression procedure, normal distances from calculated profiles to data points are minimized. For indium, the density and surface tension measurements yield p(mp) = 7.05 X 10(3) kg/m(3), dp/dT = -0.776 kg/m(3) .degrees C, and gamma(mp) = 0.568 N/m, d gamma/dT = -9.45 x 10(-5) N/m .degrees C. The results for uranium at the melting point are p(mp) = 17.47 x 10(3) kg/m(3) and gamma(mp) = 1.653 N/m.

AB Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal-dominant disorder which has been mapped to the 4q35 region, In order to saturate this distal 4q region with DNA markers, a laser-based chromosomal microdissection and microcloning procedure was used to construct a genomic library from the distal 20% of chromosome 4, derived from a single human metaphase spread.
Of the 100 microclones analyzed from this library, 94 clones contained inserts sized from 80-800 bp, with an average size of 340 bp. Less than 20% of these clones hybridized to human repeat sequences, Seventy-two single-copy clones were further characterized by Southern blot hybridization against a DNA panel of somatic cell hybrids, containing various regions of chromosome 4, Forty-two clones mapped to chromosome 4, of which 8 clones mapped into the relevant 4q35 region, Twenty of these chromosome 4-specific clones were screened against ''zoo-blots''; 11 clones, of which 3 mapped to 4q35, identified conserved sequences.
This is the first report to describe the isolation of potential expressed sequences derived from the FSHD region, These chromosome region-specific microclones will be useful in the construction of the physical map of the region, the positional cloning of potential disease-associated genes, and the identification of additional polymorphic markers from within the distal 4q region.

ID METALLIC-GLASS; DISPERSION
AB Inelastic neutron scattering measurements have been made with momentum transfers within the first pseudo-Brillouin zone of a magnesium/zinc glass at 100 K and 297 K. We describe the application of a new spectrometer (PHAROS) for these studies. Because the longitudinal velocity of sound is about 4300 m s(-1), a high incident neutron energy (0.187 eV) was required. Data have been obtained down to Q similar or equal to 8 nm(-1) and HBAR omega = 25 meV well inside the first pseudo-Brillouin zone of the glass. Evidence for two predominantly longitudinal excitations in the Mg70Zn30 glass is presented. Their positions agree approximately with theoretical predictions.

AB The heat capacities of some liquid alkali-lead and alkali-tin alloys exhibit anomalous behaviour as a function of both composition and temperature. The equiatomic composition is characterized by a large excess heat capacity which depends strongly upon temperature. Taking into account the thermodynamic properties and structural measurements, we propose a model for these alloys based on a dissociation scheme of polyvalently charged anions into either free atoms, ions or some other small entities.

AB The local molecular structure of amorphous polyaniline (PANI) film in the emeraldine oxidation state has been studied using radial distribution function analysis of X-ray scattering data in combination with model calculations. As-cast emeraldine base (EB) films exhibit an interchain ordering that is significantly poorer than that for the intrachain structure. Protonic acid (HBr or HCl) doping of these films, to yield the electrically conductive emeraldine salt (ES) form of PANI, leads to significant changes in both the intrachain and interchain structure of the polymer chains. Structural changes in the intrachain ordering are found to be essentially reversible on undoping since, after all of the dopant is removed from ES films by immersion in a strong base solution, the original as-cast EB intrachain features become more pronounced. In contrast, evidence of irreversible changes in the interchain. packing is observed during this doping/undoping process following the treatment with base. These changes in the EB local molecular ordering may be intimately coupled to the electronic properties intrinsic to conducting polymers and they occur in such a way that subsequent exposure to protonic acids initiates a highly site-specific redoping of the polymer host. These findings shed light on the doping-induced variations of the physical properties in conducting polymers such as charge and mass transport through polyaniline films.

AB This analysis, based on a sample of 170000 hadronic Z(0) decays, provides a measurement of the K-+/- and p/($) over bar p differential cross sections which is compared to string- and cluster fragmentation models. The total multiplicities for K-+/- and pip per hadronic event were found to be: N-K = 2.26 +/- 0.18 and N-p = 1.07 +/- 0.14. The positions xi* of the maxima of the differential cross sections as a function of xi = In(1/x(p)) for K-+/- and p/($) over bar p were determined to be 2.63 +/- 0.07 and 2.96 +/- 0.16 respectively. A comparison of the xi* values for various identified particles measured at LEP with the prediction of the Modified Leading Logarithm Approximation with Local Parton Hadron Duality model has been performed. The measured xi* position as a function of the hadron mass, after corrections due to particle decays, is in agreement with the model calculation.

AB Applying a technique developed in a recent work [L.H. Yu and C.P. Sun, Phys. Rev. A 49 (1994) 592] to calculate wavefunction evolution in a dissipative system with Ohmic friction, we show that the wavelength of the wavefunction decays exponentially, while the Brownian motion width gradually increases. In an interference experiment, when these two parameters become equal, the Brownian motion erases the fringes and the system thus approaches the classical limit. We show that the wavelength decay is an observable phenomenon.

AB Calculations up to the MP2/6-31G*//HF/3-21G level have been carried out to study the thermal cycloreversion of 2,2,6-trimethyl-4H-1,3-dioxin-4-one (1) and 2,2,4-trimethyl-6H-1,3-oxazin-6-one (3). At this level of calculation, the enthalpy of activation for the thermal cycloreversion of dioxinone 1 was found to be 31.3 kcal/mol with zero-point vibrational energy correction. The experimental value for the reaction in solution is 30.4 kcal/mol. The enthalpy of activation for the as of yet unsynthesized oxazinone 3 was found to be 44.2 kcal/mol with zero-point correction. Contrasting with the standard view that the thermal cycloreversion of dioxinone 1 is a retro-Diels-Alder reaction is the structural information from the HF/3-21G-optimized transition state 5 which shows the plane of the acetone dienophile tilted roughly 90 degrees to the plane of the acylketene diene.

ID MAMMARY EPITHELIAL-CELLS; LINES; AMPLIFICATION
AB We have used culture conditions which simulate the microenvironment of breast tumors for the isolation and propagation of primary breast tumor cells in vitro. In this monolayer setup, the mixture of cells dissociated from primary breast tumors is subjected to self-created gradients of oxygen and nutrients as well as metabolic waste and extracellular pH. The tumor populations isolated under these novel conditions have displayed phenotypic properties characteristic of breast carcinomas, including homogeneous expression of cytokeratin 19, and increased mitochondrial retention of the cationic dye rhodamine 123. Nonmalignant cultures from reduction mammoplasty were unable to survive these conditions. One tumor population which reached passage 10 was aneuploid for chromosomes 15 and 17, and displayed a p53 mutation in exon 8. These studies strongly suggest that the culture conditions described here can suppress the growth of normal breast cells, thereby allowing selective isolation of some populations of slow-growing primary tumor cells in vitro.

ID CESN3
AB The intermetallic compound YbAl3 (cubic AuCu3 structure type) has been usually classified as an intermediate valence system. As many rare earth intermetallics it might be in general described by the Anderson model for the f-electron hybridization with the conduction electrons. To understand in detail the electron hybridization, the magnetization of a flux-grown YbAl3 single crystal was investigated with a SQUID-magnetometer at different temperatures in applied fief ds up to B=5T. Measurements along the crystallographic axes [100] and [110] show no anisotropy. We used the same single crystal for determining the magnetic susceptibility in the temperature range between T=2 K and T=300 K. We have observed the well-known maximum at T=130 K in agreement with earlier measurements on polycrystals. This maximum as well as a Curie-Weiss-temperature dependence at higher temperatures are typical features of many Ce- and Yb-compounds. For T<6 K the magnetic susceptibility increases rapidly when temperature is decreased. This increase might be explained with a magnetic impurity contamination of less than 100 ppm. Due to this high purity of the sample we could directly measure a small maximum of (chi)(T) at T=15 K, that was earlier only separated by subtracting the larger impurity contribution. This maximum has to be taken into account when describing the hybridization process in detail.

AB Recent investigations have considered whether it is possible to achieve early detection of greenhouse-gas-induced climate change by observing changes in ocean variables. In this study we use model data to assess some of the uncertainties involved in estimating when we could expect to detect ocean greenhouse warming signals. We distinguish between detection periods and detection times. As defined here, detection period is the length of a climate time series required in order to detect, at some prescribed significance level, a given linear trend in the presence of the natural climate variability. Detection period is defined in model years and is independent of reference time and the real time evolution of the signal. Detection time is computed for an actual time-evolving signal from a greenhouse warming experiment and depends on the experiment's start date. Two sources of uncertainty are considered: those associated with the level of natural variability or noise, and those associated with the time-evolving signals. We analyze the ocean signal and noise for spatially averaged ocean circulation indices such as heat and fresh water fluxes, rate of deep water formation, salinity, temperature, transport of mass, and ice volume. The signals for these quantities are taken from recent time-dependent greenhouse warming experiments performed by the Max Planck Institute for Meteorology in Hamburg with a coupled ocean-atmosphere general circulation model. The time-dependent greenhouse gas increase in these experiments was specified in accordance with scenario A of the Intergovernmental Panel on Climate Change. The natural variability noise is derived from a 300-year control run performed with the same coupled atmosphere-ocean model and from two long (>3000 years) stochastic forcing experiments in which an uncoupled ocean model was forced by white noise surface flux variations. In the first experiment the stochastic forcing was restricted to the fresh water fluxes, while in the second experiment the ocean model was additionally forced by variations in wind stress and heat fluxes. The mean states and ocean variability are very different in the three natural variability integrations. A suite of greenhouse warming simulations with identical forcing but different initial conditions reveals that the signal estimated from these experiments may evolve in noticeably different ways for some ocean variables. The combined signal and noise uncertainties translate into large uncertainties in estimates of detection time. Nevertheless, we find that ocean variables that are highly sensitive indicators of surface conditions, such as convective overturning in the North Atlantic, have shorter signal detection times (35-65 years)than deep-ocean indicators (greater than or equal to 100 years). We investigate also whether the use of a multivariate detection vector increases the probability of early detection. We find that this can yield detection times of 35-60 years (relative to a 1985 reference date) if signal and noise are projected onto a common ''fingerprint'' which describes the expected signal direction. Optimization of the signal-to-noise ratio by (spatial) rotation of the fingerprint in the direction of low-noise components of the stochastic forcing experiments noticeably reduces the detection time (to 10-45 years). However, rotation in space alone does not guarantee an improvement of the signal-to-noise ratio for a time-dependent signal. This requires an ''optimal fingerprint'' strategy in which the detection pattern (fingerprint) is rotated in both space and time.

ID YBA2CU3O6+X; POWDER
AB Post-sintering treatments, such as zone melting under a thermal gradient, have been conducted on sintered YBCO tape cast films. YBCO precursor powder was derived through decomposition of a mixture of nitrates of cations in a microwave oven for similar to 4 min. The resulting powder was characterized and made into thin sheets by tape casting and then sintered at 945 degrees C for 5 h. The sintered tapes were subjected to repeated zone refining operations at the relatively high speed of similar to 30 mm h(-1). A microstructure having uniformly orientated grains in the a-b plane throughout the bulk of the sample was obtained by three repeated zone refining operations. Details of precursor preparation, microwave processing and its advantages, zone refining conditions and microstructural features are presented in this paper.

ID ALCL3-NACL MELTS; EQUILIBRIA
AB The solubility of CoCl2 in molten NaCl-AlCl3 was determined by aliquot sampling at 255 degrees C for acidic and basic solvent compositions. There was a pronounced compositional dependence of the solubility with a minimum at approximately the equimolar solvent composition. The solubility minimum was 1.04 x 10(-4) mol fraction of CoCl2. The solubility in the highly ordered NaCl-AlCl3 solutions was described in chemical terms. The true solubility product for CoCl2 was calculated as 1.50 x 10(-15) In basic and in somewhat acidic melts, the solubility was primarily related to the formation of the associated ionic species CoCl+, CoCl2, CoCl3-, and CoCl42-. The calculated formation constant of CoCl+ was 9.48 x 10(6), Furthermore, the specific bond free energy for the associated complex, CoCl+, was -64.43 kJ mol(-1) for a coordination number of four.

AB The texture study of two-phase materials requires a previous knowledge of the distribution of strains among both phases. The way they rotate around one another is of special interest. The texture is a phenomenon that manifests itself at medium and high deformations. Therefore the study cannot usually be performed experimentally, particularly when we are dealing with high volume fraction contents. Sharing of strains is also very important in many technological applications such as forming. This paper presents a study, by the finite element technique, of those quantities as a function of volume fraction, geometry, distribution, strain hardening and yield stress ratio between the two phases. Both phases are assumed to be elasto-plastic and isotropic materials. It is shown that strains and internal rotations are highly influenced by the topology of the phase distribution, yield stress ratio and volume fraction. For high yield stress ratio the hardening seems to be of less importance. It is shown that the strain is highly inhomogeneous and that averages of appropriate quantities can give a macroscopic insight on strain and rotation sharing. Among the many strain definitions the equivalent von Mises deformation will be particularly addressed for its importance in hardening, damage and texture. The local variations are not less important, but the focus will be on the calculation of average quantities able to guide to macroscopic constitutive equation development.

AB The measured linear thermal expansion coefficients alpha of hot-pressed SiC-whisker-reinforced aluminas decrease as the SiC whisker content is increased from 1 to 60 vol.%. However, owing to the preferred orientation of the whiskers, the alpha value for each SiC whisker content is greater in the direction parallel compared with the direction perpendicular, to the hot-pressing axis. The observed behavior is generally consistent with that predicted by a model based on the effects of internal thermal mechanical mismatch strains in composites with oriented reinforcements.

AB ONE Of the long-standing mysteries associated with the high-temperature copper oxide superconductors concerns the anomalous suppression(1) of superconductivity in La2-xBaxCuO4 (and certain related compounds) when the hole concentration x is near 1/8. Here we examine the possibility that this effect is related to dynamical two-dimensional spin correlations, incommensurate with the crystal lattice, that have been observed in La2-xSrxCuO4 by neutron scattering(2-4). A possible explanation for the incommensurability involves a coupled, dynamical modulation of spin and charge in which antiferromagnetic 'stripes' of copper spins are separated by periodically spaced domain walls to which the holes segregate(5-9). An ordered stripe phase of this type has recently been observed in hole-doped La2NiO4 (refs 10-12). We present evidence from neutron diffraction that in the copper oxide material La1.6-xNd0.4SrxCuO4, with x=0.12, a static analogue of the dynamical stripe phase is present, and is associated with an anomalous suppression of superconductivity(13,14). Our results thus provide an explanation of the '1/8' conundrum, and also support the suggestion(15) that spatial modulations of spin and charge density are related to superconductivity in the copper oxides.

AB The Fermilab Linac has been upgraded by the replacement of four 201.25 MHz drift tube linac tanks with seven 805 MHz side-coupled cavity modules. The reduction in physical aperture of the side-coupled modules has made control of the transverse beam position a more important consideration. An algorithm has been implemented to achieve a global least-squares minimization of beam position errors. Under typical operating conditions the RMS error in the horizontal plane is reduced by a factor of 8 (from 0.54 mm to 0.07 mm) and in the vertical plane by a factor of 4 (from 0.59 mm to 0.14 mm).

The first is the calculation of the dose to the magnet coil insulation from synchrotron radiation escaping the stainless steel vacuum chamber in the straight sections of the Nigh Energy Ring. Emphasis is given on the spectral sampling and the normalization of the Monte Carlo dose results.

ID GRATINGS
AB We have fabricated subwavelength diffractive optical elements with binary phase profiles for operation at 975 nm. The individual surface-relief features of the elements are smaller than the wavelength of light in the material. By modulating the size and spacing of the features we form artificial, gradient, effective index-of-refraction surfaces. The blazed transmission gratings were designed with rigorous coupled-wave analysis and fabricated by direct-write electron-beam lithography and reactive ion-beam etching in GaAs. The gratings have minimum features 63 nm wide. Transmission measurements show 85% diffraction efficiency into the first order.

AB We investigate the spatial behavior of the electric field for optical bistability in the good cavity limit. We show that stable spatially localized solutions exist in one and two dimensions. In addition we find that stable one-dimensional hole solutions also arise in this driven non-eqilibrium system with dissipation and dispersion thus demonstrating that stable holes are not restricted to dispersive systems, but can emerge in strongly dissipative systems as well. A critical comparison with the properties of stable localized solutions in other driven dissipative systems is also included.

AB Experiments at the LHC are sensitive to the presence or absence of matter quanta at mass scales far beyond the scales they can probe directly. The production of Z boson pairs by gluon-gluon fusion is greatly enhanced if there are ultraheavy quanta that carry SU(3)(Color) and get their mass from electroweak symmetry breaking. For example, a fourth generation quark doublet with an arbitrarily heavy mass would induce a large excess in the ZZ yield that could be detected at the LHC with only similar or equal to 10% of the design luminosity.

AB We construct a prototype of topcolor-assisted technicolor in which, although both top and bottom quarks acquire some mass from extended technicolor, strong U(1) couplings of technifermions are isospin symmetric and all gauge anomalies vanish. There is a mechanism for mixing between the light and heavy generations and there need be no very light pseudo-Goldstone bosons.

AB We have analyzed one-prong tau decays with neutral kaons using the information from a fine-grained hadron calorimeter. The data sample consists of 43 500 Z --> tau(+) tau(-) (gamma) events collected by the L3 detector at LEP in 1991, 1992 and 1993. The following branching fractions are measured: Beta(tau(-) --> upsilon(tau)pi(-)($) over bar K-0) = 0.0095 +/- 0.0015(stat) +/- 0.0006(syst); Beta(tau(-) --> nu(tau)pi(-)pi(0) ($) over bar K-0) = 0.0041 +/- 0.0012(stat) +/- 0.0003(syst) and Beta(tau(-) -->nu(tau)pi(-)($) over bar K-0 ($) over bar K-0) = 0.0031 +/- 0.0012(stat) +/- 0.0004( syst).

DE CHEMICAL VAPOR DEPOSITION; COPPER; DEPOSITION PROCESS; POLYMERS
ID POLY(TETRAFLUOROETHYLENE); ADHESION
AB A new process has been developed to produce patterned copper films with small feature sizes on polytetrafluoroethylene (PTFE). In the first step a sodium naphthalenide etching solution was used to chemically modify PTFE and also create a rough surface which provided good adhesion characteristics. In the second step a KrF excimer laser irradiated the substrate through a mask, ablating the etched layer and leaving a pattern. The typical total absorbed laser energy required to ablate the etched layer was 575 mJ cm(-2) and X-ray photoelectron spectroscopy (XPS) analysis showed that the ablated region had a composition similar to that of unmodified PTFE. In the third step, high purity copper was deposited selectively on the unablated regions in a cold wall reactor using (hfac)Cu(VTMS) (hfac = hexafluoroacetylacetonate; VTMS = vinyltrimethylsilane) at deposition rates up to 1 mu m min(-1) at 180 degrees C and 10 mTorr partial pressure of (hfac)Cu(VTMS) to give films 15-20 mu m thick of high purity copper on PTFE. Film resistivities were near bulk values. There are several advantages to this procedure compared with conventional approaches: (1) wet etching and liquid wastes are avoided; (2) conducting paths with dimensions less than 20 mu m can be produced; (3) excellent adhesion is obtained; (4) owing to the high energy density available from an excimer laser, rapid throughput is possible.

AB Techniques for improved copper chemical vapour deposition (CVD) processing by the addition of trimethylvinylsilane (tmvs) and hexafluoroacetylacetone (Hhfac) during copper deposition from the volatile liquid precursor Cu(hfac)(tmvs) are described. The tmvs enables stable high vaporization rates of precursor by direct liquid injection and the Hhfac permits higher deposition rates of smoother copper films. The resistivity of the copper films averages approximately 1.8 mu Omega cm as deposited. Combined together, these results mark an important advance toward a manufacturable copper CVD process.

AB Electroless or chemical vapor deposition of copper onto commercial samples of skived poly(tetrafluoroethylene) (PTFE) that have been chemically etched with sodium naphthalenide results in Cu films sufficiently adherent that attempts to remove the Cu cause near-cohesive failure in the PTFE. Such strong Cu adhesion forms the basis for several approaches to the production of high-resolution PTFE-based printed-circuit boards. Similarly strong adhesion does not occur to melt-processed fluorocarbon polymers (Teflon-AF, FEP, Teflon-PFA, etc.) nor to samples of PTFE annealed by hot pressing or mechanical polishing, nor to radiation-crosslinked PTFE. Adhesion to etched, skived PTFE is dominated by mechanical interlocking due to penetration of Cu into the highly-crazed, porous surface produced by etching of the stressed surface caused by skiving. Patterned irradiation (electrons, X-rays, etc.) at low dose levels results in crosslinking of virgin PTFE, preventing appreciable chemical etching and subsequent metal adhesion in the irradiated areas, and resulting in a three-step process (irradiation, chemical etching, and metal deposition) with a non-optimized lateral resolution of 35 mu m. Optical power absorption by an etched PTFE layer is a factor of 300 greater than for underlying (virgin) PTFE, allowing a second three-step approach to patterned metallization: chemical etching, patterned excimer-laser ablation, and metal deposition. A third approach combines chemical etching and uniform thin-metal-film deposition with standard photolithographic processing techniques, resulting in a patterned metallization process where adhesion is controlled by the initial etching step and resolution is controlled by standard lithographic technology. A non-optimized feature resolution of 17 mu m for 4-mu m thick Au conductors has been demonstrated with this technique.

AB Reactively sputtered from a W2B target, amorphous W-B-N thin films are investigated. The physical properties of the films, namely density, resistivity, crystallization behavior and reaction temperature with silicon, are given as functions of composition. Additionally, the films are assessed as diffusion barriers between silicon substrates and copper overlays. By I(V) measurements of shallow-junction diodes, a 100 nm W64B20N16 barrier prevents copper from reaching the silicon during an 800 degrees C, 30 min heat treatment in vacuum. W79B21 films are able to prevent diffusion into the diodes only up to 500 degrees C. High resolution transmission electron microscopy shows that W64B20N16 and W79B21 films are both marginally amorphous with local ordering of less than 1.5 nm.

AB Quadrupole and octupole correlations in Pb-194 are investigated by means of the generator coordinate method, Static microscopic wave functions are obtained by constrained Hartree-Fock+BCS calculations using the effective interaction SkM*. Quadrupole deformations from ground state to hyperdeformation region are included. Superdeformed band heads of both parities are predicted. The depopulation of the even superdeformed band is calculated. The odd-parity superdeformed band slowly decays to the ground even-parity superdeformed band over many E1 transitions.

AB The realizable Markovian closure (RMC) developed by Bowman et al. [Phys. Fluids B 5 (1993) 3558] is employed to study the Hasegawa-Wakatani model, a paradigm for resistive drift-wave turbulence. Turbulent transport, spectral properties, and energy-transfer directions are discussed. For second-order statistics, the closure predictions are in excellent agreement with direct numerical simulations. A marked depression of the hydrodynamic flux from its quasilinear value is well predicted by the RMC and is explained without reference to ''coherent structures''.

AB In the macronucleus of the ciliate Oxytricha nova, telomeres end with single-stranded (T(4)G(4))(2) DNA bound to a heterodimeric telomere protein (alpha beta) Both the alpha and beta subunits (alpha-TP and beta-TP) were phosphorylated in asynchronously growing Oxytricha; beta-TP was phosphorylated to a much higher degree, In vitro, mouse cyclin-dependent kinases (Cdks) phosphorylated beta-TP in a lysine-rich domain that is not required for specific DNA binding but is implicated in higher order structure formation of telomeres, Therefore, phosphorylation of beta-TP could modulate a function of the telomere protein that is separate from specific DNA binding. Phosphoamino acid analysis revealed that the mouse Cdks modify predominantly threonine residues in beta-TP, consistent with the observation that beta-TP contains two consensus Cdk recognition sequences containing threonine residues, In Xenopus egg extracts that undergo cell cycling, beta-TP was phosphorylated in M phase and dephosphorylated in interphase. This work provides the first direct evidence of phosphorylation at telomeres in any organism, as well as indirect evidence for cell cycle regulation of telomere phosphorylation. The Cdc2/cyclin A and Cdc2/cyclin B kinases are required for major mitotic events. An attractive model is that phosphorylation of beta-TP by these kinases is required for the breakdown of telomere associations with each other and/or with nuclear structures prior to nuclear division.

TI LIGATION OF HEXAMERS ON HEXAMER TEMPLATES TO PRODUCE PRIMERS FOR CYCLE
SEQUENCING OR THE POLYMERASE CHAIN-REACTION
SO ANALYTICAL BIOCHEMISTRY
LA English
DT Article
ID DNA; LIBRARY; WALKING; STRINGS
AB A method is described for the ordered ligation of hexanucleotides (hexamers) in solution to produce unique longer oligonucleotides. To form an 18-mer, for example, six different hexamers are selected that can base pair unambiguously to form a double-stranded complex of indefinite length. In the most efficient arrangement, each hexamer forms three complementary base pairs with two other hexamers, generating complementary chains of contiguous hexamers with strand breaks staggered by three bases. Two adjacent hexamers in one chain contain 5' phosphate groups and the others are unphosphorylated. Both T4 and T7 DNA ligase can ligate the phosphorylated hexamers to their neighbors in such a complex at hexamer concentrations in the 50-100 mM range, producing an 18-mer and leaving three unphosphorylated hexamers. Twenty-nine of 34 complexes that satisfied the requirements for unambiguous ligation generated the desired 18-mers, which could be used directly for cycle sequencing or, after removal of the unreacted hexamers, for polymerase chain reactions (PCR). Comparable ligation reactions also produced 12-, 24-, and 30-mers. With a library of all 4096 possible hexamers, unambiguous ligation has the potential to produce more than 82% of ah possible 18-mers and could readily supply the oligonucleotides needed for DNA sequencing by primer walking, for PCR, or for gene synthesis.

We have expanded this strategy using overlapping YACs and P1s from human 21q22.2 (the Down syndrome region) to create a panel of transgenic mice containing DNA that encompasses this region of the human genome. Together the members of the in vivo library, each with a unique transgene (four YACs and four P1s), contain approximately 2 Mb of contiguous DNA. The integrity, stable inheritance, and expression of a coding sequence for each member of the YAC panel are demonstrated, and the uses of the panel are described. (C) 1995 Academic Press, Inc.

AB In the mouse, the embryonic ectoderm development (eed) region is defined by deletions encompassing the albino (c) locus of chromosome 7. The region is located 1-2 cM distal to the c locus and was of undetermined size. Embryos homozygous for deletions removing eed display defects in axial organization during gastrulation. Two loci, identified by chemical mutagenesis, are known to map within the eed interval. One, l7Rn5, probably represents the gene required for gastrulation. The second, l7Rn6, is required for survival after birth. fit1, a third locus identified by chemical mutagenesis, maps distal to the eed interval and is also required for survival after birth. A 900-kb YAC contig has been constructed, and deletion breakpoints defining the limits of the regions containing these loci have been localized, Their positions place the eed region within a maximum 150-kb interval at the proximal end of the contig, while fit1 maps to a 360-kb interval within the middle of the contig. Several clusters of rare-cutting restriction sites map within these regions and represent potential locations of candidate genes. (C) 1995 Academic Press, Inc.

TI THE MOTION OF LONG BUBBLES IN POLYGONAL CAPILLARIES .1. THIN-FILMS
SO JOURNAL OF FLUID MECHANICS
LA English
DT Article
ID MENISCI
AB Foam in porous media exhibits an unusually high apparent viscosity, making it useful in many industrial processes. The rheology of foam, however, is complex and not well understood. Previous pore-level models of foam are based primarily on studies of bubble flow in circular capillaries. A circular capillary, however, lacks the corners that characterize the geometry of the pores. We study the pressure-velocity relation of bubble flow in polygonal capillaries. A long bubble in a polygonal capillary acts as a leaky piston. The 'piston' is reluctant to move because of a large drag exerted by the capillary sidewalls. The liquid in the capillary therefore bypasses the bubble through the leaky corners at a speed an order higher than that of the bubble. Consequently, the pressure work is dissipated predominantly by the motion of the fluid and not by the motion of the bubble. This is opposite to the conclusion based on bubble flow in circular capillaries. The discovery of this new flow regime reconciles two groups of contradictory foam-flow experiments.
Part 1 of this work studies the fluid films deposited on capillary walls in the limit Ca-->0 (Ca = mu U/sigma, where mu is the fluid viscosity, U the bubble velocity, and sigma the surface tension). Part 2 (Wong et al. 1995) uses the film profile at the back end to calculate the drag of the bubble. Since the bubble length is arbitrary, the film profile is determined here as a general function of the dimensionless downstream distance x. For 1 much less than x much less than Ca-1, the film profile is frozen with a thickness of order Ca-2/3 at the centre and order Ca at the sides. For x similar to Ca-1, surface tension rearranges the film at the centre into a parabolic shape while the film at the sides thins to order Ca-4/3. For x much greater than Ca-1, the film is still parabolic, but the height decreases as film fluid leaks through the side constrictions. For x similar to Ca--5/3, the height of the parabola is order Ca-2/3. Finally, for x much greater than Ca--5/3, the height decreases as Ca(1/4)x(-1/4).

PRESSURE AND FLUID-FLOW
SO JOURNAL OF FLUID MECHANICS
LA English
DT Article
AB This work determines the pressure-velocity relation of bubble flow in polygonal capillaries. The liquid pressure drop needed to drive a long bubble at a given velocity U is solved by an integral method. In this method, the pressure drop is shown to balance the drag of the bubble, which is determined by the films at the two ends of the bubble. Using the liquid-film results of Part 1 (Wong, Radke and Morris 1995), we find that the drag scales as Ca-2/3 in the limit Ca-->0 (Ca = mu U/sigma, where mu is the liquid viscosity and sigma the surface tension). Thus, the pressure drop also scales as Ca-2/3. The proportionality constant for six different polygonal capillaries is roughly the same and is about a third that for the circular capillary.
The liquid in a polygonal capillary flows by pushing the bubble (plug flow) and by bypassing the bubble through corner channels (corner flow). The resistance to the plug flow comes mainly from the drag of the bubble. Thus, the plug flow obeys the nonlinear pressure-velocity relation of the bubble. Corner flow, however, is chiefly unidirectional because the bubble is long. The ratio of plug to corner flow varies with liquid flow rate Q (made dimensionless by sigma a(2)/mu, where alpha is the radius of the largest inscribed sphere). The two flows are equal at a critical flow rate Q(c), whose value depends strongly on capillary geometry and bubble length. For the six polygonal capillaries studied, Q(c) much less than 10(-6). For Q(c) much less than 1, the plug flow dominates, and the gradient in liquid pressure varies with Q(2/3). For Q much less than Q(c), the corner flow dominates, and the pressure gradient varies linearly with Q. A transition at such low flow rates is unexpected and partly explains the complex rheology of foam flow in porous media.

AB Electrical conductivity of a water-saturated quartz-mica-garnet-schist, collected from a surface outcrop near the Denali Fault Zone in the Yukon-Tanana terrane of east central Alaska, increases slightly with pressure to about 200 MPa, This behavior is unlike that exhibited by other Yukon-Tanana samples or by most rocks from other locations, Detailed petrographic examination of the sample revealed the presence of a stringer of carbonaceous material generally less than 10 mu m thick enclosed in and intergrown with one of the muscovite layers and extending for about 2 cm along the foliation, The stringer is probably responsible for the anomalous conductivity change with pressure, making the sample the first for which anomalous electrical conductivity behavior can be attributed to carbon associated with a specific feature, The carbonaceous stringer together with its host muscovite layer are deformed and broken around a rotated garnet porphyroclast, The deformation was accommodated by plastic deformation of quartz and therefore occurred in the ductile regime under conditions at least equivalent to greenschist facies metamorphism, We interpret the textural relations to indicate that the carbonaceous material was formed by fluid deposition in a fracture formed within the muscovite layer, possibly during the main phase of metamorphism and deformation, and that the mica and carbon stringer were then deformed by the noncoaxial deformation responsible for rotation of the garnet porphyroclasts. Together the facts that the deformation resulting in garnet rotation was ductile and that the garnet rotation disrupted the stringer demonstrate that the carbonaceous stringer was present at depth (i,e,, > 10 km). Brittle deformation on the microscopic scale is observed to have broken the connectivity of the carbon stringer, explaining in part why the rock does not exhibit anomalously high conductivity at 0.1 MPa (1 atm) pressure, The brittle deformation is interpreted to have been caused by unloading due to uplift. The observations indicate that carbonaceous material may exert a primary control on crustal electrical conductivity because it may be present as interconnected arrays in grain boundaries or microfractures or in megascopic, throughgoing fractures.

A sharp onset of noise occurring at T-on < T-c2(H) is a new feature. A separate noise peak shows striking correlation to hysteresis previously observed in single crystals and is interpreted as melting. The temperature of both features did not change over two decades in the applied current, indicating that they may be signatures of thermodynamic transitions within the vortex state.

AB We take the single-crystalline (La1-xSrx)(2)CuO4 system (x = 0.068) as an example to study flux dynamics in the mixed state of high-T-c superconductors by systematically measuring its c-axis resistivity, rho(c), as a function of temperature, magnetic-field intensity and magnetic-field orientation with respect to the ab-plane. We firstly show the experimental evidence that excludes the contribution of Lorentz force driven flux motion to the c-axis resistive dissipation. Furthermore, we argue that neither the vortex dynamics for conventional anisotropic superconductors nor the two-dimensional pancake vortices model is appropriate for the present system. We then demonstrate the difficulty of the previously considered Lorentz force free dissipation models in explaining the present experimental observations. Finally, a phenomenological model is introduced, in which the phase slippage model developed by Ambegaokar and Halperin is extended to the case of the c-axis resistivity by taking into account the following two main features: (1) the intrinsic layered structures along the c-axis, and (2) the irreversibility line, T-irr(H), corresponding to a vortex glass-liquid transition. To show the advantages of the present model, we compare the model with the experimental rho(c)(T, H) data for H parallel to c, which gives excellent agreement in almost the whole transition region (five decades).

AB We report our observations on and identification of an intermediate phase, (Bi,Pb)(4)Sr4Ca3Cu5O18 (+) (delta) (denoted as Bi/4435), during the phase transformation of (Bi,Pb)(2)Sr2CaCu2O8+delta (Bi/2212) to (Bi,Pb)(2)Sr2Ca2Cu3O10+delta (Bi/2223) in powder-in-tube processed tapes. The unit cell of the phase consists of one half each of the Bi/2212 and the Bi/2223 cell, with lattice parameters of a approximate to b = 5.4 Angstrom and c = 33.9 Angstrom. The space group of the new phase was determined to be Pbmn using the extinction rule of the selected-area electron diffraction, as well as convergent beam electron diffraction and high-resolution electron microscopy. The presence of the Bi/4435 phase and the abundance of its local structure during the early stage of the transformation suggests that the Bi/2223 phase is formed by the rapid insertion of two extra Ca/CuO bi-layers, one at a time, into the two identical CuO/Ca/CuO building blocks of the Bi/2212 matrix. This finding may shed light on the mechanism of structural phase transformation in layered cuprate superconductors.

AB The reactions of dichlorosilane (SiCl2H2) with Ge(100) and Ge(111) are investigated with soft X-ray photoelectron spectroscopy excited by synchrotron radiation. SiCl2H2 is found to dissociatively chemisorb at all temperatures. At room temperature, the adsorbed layer is composed of multiple silicon chlorides and hydrides. At exposure temperatures between 200 and 400-degrees-C, the surfaces are covered primarily by SiCl with some higher chlorides and unchlorinated Si also present. The specific distributions of these species are slightly different on Ge(100) and Ge(111), with greater concentrations of higher silicon chlorides on Ge(111). For exposures in the range of 500 to 600-degrees-C, pure Si is deposited onto the surfaces, likely in the form of islands. For exposures at 700-degrees-C, Si is also interdiffused into the Ge substrate.

AB The interaction of atomic deuterium with diamond (100) has been studied by X-ray photoelectron spectroscopy (XPS). Reproducible cleaning and conditioning procedures have been developed using atomic hydrogen exposure and heating to 1450 K in ultrahigh vacuum. As the clean diamond surface is exposed to atomic deuterium, the FWHM of the C 1s transition initially broadens for low atomic deuterium exposures. Increasing the atomic deuterium exposure results in a sharpening of the C 1s transition. This is essentially reversible by stepwise heating to desorb the deuterium. The C 1s broadening/sharpening phenomenon may be due to the electronic inhomogeneity caused by partial deuteration of the surface region sampled by XPS. Complete deuteration leads to a more homogeneous chemical environment and thus the C 1s line sharpens. These results suggest that deep deuteration of diamond (100) may take place upon exposure to atomic deuterium. The inhomogeneity of the surface region caused by Ar+ ion bombardment has a similar broadening effect on the C 1s line. Charging effects were found to be insignificant. Deuteration of the diamond (100) surface by atomic deuterium results in apparent shifts of the C 1s binding energy, dependent (in sign) upon n-type or p-type doping in the diamond. This is consistent with band bending effects in the surface region caused by the removal of the surface state by deuterium adsorption. It is demonstrated that graphite overlayers on diamond cannot be removed with atomic D or molecular oxygen at high temperatures.

ID ELECTRON PHOTODETACHMENT; DETACHMENT; SELECTIVITY; ATTACHMENT
AB The photodetachment cross section for SF6- and the photodetachment threshold for this process have been accurately measured using a newly developed technique. The photodetachment cross section has a threshold at 3.16 eV which is about three times larger than the electron affinity of the SF, molecule. The magnitude of the photodetachment cross section increases monotonically from the threshold to 1.0 X 10(-18)cm(2) at a photon energy of 3.46 eV. The small size of the measured cross section is attributed to the large relaxation in the equilibrium internuclear positions of SF6- compared to SF6; the analysis of the data indicates that the photoejected electron has an angular momentum quantum number l = 1.

AB A basis expansion of a quantum state of a molecule in a small orthogonal set of dynamically motivated, active bright states is presented and tested. The active bright states are derived from wavepackets (in a discrete variable representation) corresponding to different times in the time evolution of the molecule in a specified external laser field. Time evolution using the active bright-state representation is computationally less intensive and contains the essential dynamics in the quasiharmonic, quasicontinuum, and continuum regimes. Knowledge of the exact molecular spectroscopy is not needed. The active bright-state representation is thus well suited for optimal-control calculations which require a large number of wavepacket propagations.

AB Packing materials do consolidate progressively inside chromatographic columns. The process is slow. The literature on the phenomenon of soil consolidation is critically reviewed and the concepts relevant to the behavior of sands are applied to conventional packing materials. Preliminary experimental results obtained with irregular-shaped particles are presented to illustrate the concepts introduced by and the conclusions of the literature survey. These results show that the consolidation of packing material in chromatographic columns is a slow process which may sometimes appear to take place as a series of ''catastrophic'' events. It involves changes in the apparent packing density of the bed which are large enough to account for the formation of large voids at the column inlet, as has been frequently reported by operators of analytical as well as large-size preparative columns.

ID MOLECULES; HYDROLYSIS; CHEMISTRY; KINETICS
AB The alkylating agent isophosphoramide mustard (IPM) spontaneously forms a relatively stable aziridine derivative which can be directly observed using NMR spectroscopy. The protonations of LPM and its aziridine were probed using H-1, P-31, N-15, and O-17 NMR spectroscopy. The positions of the P-31, N-15, and O-17 resonances of IPM between pH 2 and 10 each exhibit a single monobasic titration curve with the same pK(a) of 4.31 +/- 0.02. On the basis of a comparison with other compounds and our earlier work with phosphoramide mustard, the NMR results for IPM indicate that protonation occurs at nitrogen and not oxygen. Over this same pH range, each of the H-1, P-31, and N-15 resonances of IPM-aziridine also show a single monobasic titration with a pK(a) of 5.30 +/- 0.09. The magnitude of the change in chemical shifts suggests that the protonation of the IPM-aziridine occurs at the ring nitrogen. Theoretical gas-phase calculations of PM, IPM, and IPM-aziridine suggest O-protonation to be more likely; however, aqueous phase calculations predict the N-protonated forms to be most stable. Furthermore, for PM and IPM-aziridine, which contain nonequivalent nitrogens, the theoretical calculations and experimental data both agree as to which nitrogen undergoes protonation. These results suggest that the IPM-aziridine remains unprotonated under physiological conditions and may, in part, explain the lower alkylating activity of IPM as compared to PM.

AB Small-angle scattering and electron microscopy studies of fd gene 5 protein (g5p) and reconstituted g5p . nucleic acid complexes have been used to test models for the complexes and evaluate their uniqueness. In addition, we have obtained new information on the dependence of nucleotide type and protein/nucleotide (P/N) ratio on the structure of the complexes. Reconstituted complexes were made with single-stranded fd viral DNA (fd ssDNA), poly[d(A)] and poly[r(A)]. All complexes form similar left-handed, flexible superhelices having approximately the same diameter, but the pitch differs among these complexes. The g5p protein is a dimer in solution and the dimers associate to form a superhelical framework to which the polynucleotide is attached. The combined X-ray and neutron scattering data confirm the nucleic acid is inside the protein superhelix. A Monte Carlo integration modeling procedure applied to the scattering data was used to systematically test large numbers of possible models for each complex, and previously proposed models based on parameters obtained from electron microscopy were found to be essentially correct and unique.

AB Experiments were designed to examine the effects of radiation dose-rate and cycloheximide on expression of cytoskeletal and matrix elements in Syrian hamster embryo cells. Results here demonstrated little effect of dose-rate for fission-spectrum neutrons when comparing expression of alpha-tubulin or fibronectin genes. Effects of cycloheximide, however, revealed several findings: (a) Cycloheximide repressed accumulation of alpha-tubulin following exposure to high dose-rate neutrons or gamma-rays. (b) Cycloheximide did not affect accumulation of mRNA for actin genes. (c) Cycloheximide abrogated the moderate induction of fibronectin-mRNA which occurred following exposure to gamma-rays and high dose-rate neutrons. These results suggest a role for labile proteins in the maintenance of alpha-tubulin and fibronectin mRNA accumulation following exposure to ionizing radiation.

AB Colloidal films of gold and silver were prepared on glass or quartz slides. The slides were derivatized with (3-mercaptopropyl)trimethoxysilane and subsequently reacted with aqueous metal colloids for variable time periods. The formation of the sulfur-metal bond provides a stable colloidal film on the surface. Because of the electrostatic interaction between individual particles, a semiregular structure is produced, as can be seen from electron micrographs. The unique property of the colloidal film is that they possess the optical properties of colloidal metals and the convenience of solid substrates. The effect of the dielectric constant of solvents on the optical frequencies, as well as the specific interaction of the solvent molecules with the metal on the plasmon resonances, was examined in detail. The colloidal films exhibit strong enhancement of Raman scattering and fluorescence emission from molecules adsorbed on the surface. Enhancement of fluorescence was observed for fluorescein-labeled molecules spaced 0-200 Angstrom away from the surface. These substrates can be used in a number of analytical applications, such as surface-enhanced spectroscopies as well as for fundamental studies of plasmon resonances in small metal particles.

AB TDS, XPS, and XAES were used to examine the reaction of S-2 gas with NM/Mo(110) (NM = Cu or Ag). On these surfaces S-2 dissociates into atomic S at 300 K. At submonolayer coverages (theta(s) + theta(NM) < 1 ML), S and Cu or Ag do not react to form noble-metal sulfides on top of Mo(110). Instead, the S and noble-metal adatoms compete for making bonds with the Mo(110) substrate. On the average, each S adatom diminishes the ability for bimetallic bonding of a minimum of three Mo surface atoms. At 0.4 < theta(s) < 0.8 ML, the weakening of the Mo-Cu and Mo-Ag bonds is very significant (>5 kcal/mol), and the noble-metal adatoms form 3D clusters on the Mo(110) surface. The exposure of NM/Mo(110) surfaces to large amounts of S-2 gas (theta(s) > 1 ML) at 300 K produces noble-metal sulfides (CuSx or AgSy) and chemisorbed sulfur, without forming molybdenum sulfides. The sulfidation of molybdenum occurs after exposing NM/Mo(110) surfaces to S-2 at 600-700 K. Cu and Ag promote (or catalyze) the formation of molybdenum sulfides. By comparing the results for the S-2/NM/Mo(110) systems with those reported for S-2/NM/Pt(111) systems, it is found that the ''promotional effect'' of a noble metal on the rate of sulfidation of a transition metal depends on (a) the ability of the noble metal to dissociate S-2, (b) the thermochemical stability of the transition-metal sulfide (which makes the process ''downhill''), and (c) the atom-atom attractive interactions within the lattice of the transition metal (which make the process ''uphill'').

AB Small-angle neutron scattering from D2O solutions of a series of organic salts, ranging from sodium toluenesulfonate to sodium triisopropylbenzenesulfonate, has been measured. Evidence of aggregation was found, at least at high concentrations, in all cases. The patterns were interpreted by the mean spherical approximation, and estimates of the size of the species are presented. Aggregate sizes increase with increase in equivalent weight. Addition of toluene increases aggregation number. A few measurements on solutions of sodium cyclohexylane carboxylates indicate that aggregates are somewhat smaller than those of aromatic salts of about the same number of carbons.

ID LANTHANIDE
AB The synthesis and characterization of the Eu-encrypted heteropolyanion [EuP5W30O110](12-) are presented. X-ray absorption near-edge structure experiments were used to determine that Eu is trivalent in the anion. Optical spectra confirm this finding. The unusual cyclic voltammogram obtained for the Eu heteropolyanion is discussed in terms of the stability of Eu-II under reducing conditions. Time delayed optical fluorescence data are only consistent with two structurally inequivalent Eu ions, both inside the heteropoly cavity. Lifetime measurements of the D-5(o) State indicate that the two structurally different Eu sites are not occupied in the same anion. In addition, from complementary measurements on samples made in D2O, it is determined that there are three waters coordinated to Eu in one site and only two waters coordinated to Eu in the second site. P-31 NMR and cyclic voltammetry data, obtained from samples with either one or two sites occupied, are indistinguishable. Possible models to explain the presence of two sites are discussed.

AB We report a detailed polarized single-crystal X-ray absorption spectroscopic study of CuCl2 . 2H(2)O, with measurements at both the copper K-edge and the chlorine K-edge. The angular dependence of both dipole-allowed and quadrupole-allowed transitions is determined in detail for the copper K-edge. The formally dipole-forbidden, quadrupole-allowed Cu K-edge 1s --> 3d transition behaves as a pure quadrupole transition, with no significant dipole contribution. The 1s --> 3d transition is found to have predominantly 3d(x2-y2) character, as expected, but evidence is also given for vacancies in a lower lying d orbital, possibly 3d(x), arising from the presence of d pi-d pi bonding with the chloride ligands. The chlorine K-edge data show a strongly polarized pre-edge resonance at similar to 2821 eV, which can be interpreted in terms of a transition from the chlorine Is orbital to an antibonding orbital with significant contributions from both chlorine 3p and the half-filled copper 3d(x2-y2) orbital.

AB Horse-heart (hh) cytochrome c, modified at His-33, and Candida krusei (Ck) cytochrome c, modified at His-39, with a series of cis- and trans-[L(NH3)(4)Ru(III)cyt c] derivatives, where L is isonicotinamide (isn) or pyridine (py), have been prepared and characterized. Rate constants for intramolecular electron transfer from the heme(II) to Ru(III) in the [L(NH3)(4)Ru(III)cyt c(II)] intermediates generated by oxidative pulse radiolysis of the fully reduced modified protein species were as follows (k (s(-1)), Delta H-double dagger (kcal mol(-1)), Delta S-double dagger (cal deg(-1)mol(-1)), -Delta G degrees (eV)): 440, 7.3, -22, 0.18 for L = trans-isn (hh); 440, 6.2, -26, 0.18 for L = cis-isn (hh); 126, 8.8, -19, 0.11 for L = trans-py (hh); 220, 6.4, -27, 0.13 for L = trans-isn (Ck); 154, 2.3, -41, 0.18 for L = NH3 (Ck). Relative differences in the rates are accounted for by variations in the driving force and reorganization energies in these ruthenium-modified proteins resulting from the nature of the ligands around the ruthenium center and from the different sites of modification on the cytochrome. The fully oxidized [L(NH3)(4)Ru(III)cyt c(III)] species undergo slow redox disproportionation reactions (k = 35 M(-1) s(-1), pH 7.0) which have been studied by optical and electrochemical methods. The Ru(IV) species thus created subsequently rearranges in an irreversible manner. In the presence of excess oxidant, all of the bound ruthenium is converted to the rearranged form. To avoid this problem, the [L(NH3)(4)Ru(III)cyt c(II)] intermediates for intramolecular electron-transfer studies were generated from the stable [L(NH3)(4)Ru(II)cyt c(II)] form.

AB The synthesis and coordination chemistry of a new asymmetric multidentate ligand designed for modeling coordination number asymmetry at metal sites in binuclear metalloproteins are described., A binuclear copper complex of this ligand demonstrates proof-of-concept for inducing coordinative unsaturation at one metal of the binuclear pair, and subsequent reaction with azide illustrates site-directed reactivity. The ligand N,N,N'-tris((N-methyl-2-benzimidazolyl)methyl)-N'-methyl- 1,3-diamino-2-propanol (HBMDP) was prepared in good yield by a five-step procedure. HBMDP reacts with the copper(II) ion in methanol to produce a mononuclear copper complex, [CuHBMDP](ClO4)(2) . CH2CN, that crystallizes in the triclinic space group with unit cell dimensions a = 10.833(3) Angstrom, b = 12.457(3) Angstrom, c = 15.214(3) Angstrom, alpha = 78.28(2)degrees, beta = 79.26(2)degrees, and gamma = 68.10(2)degrees. A single-crystal X-ray structure shows that the copper ion is coordinated to the five nitrogen donor atoms in a distorted trigonal bipyramid. The hydroxo oxygen of the ligand does not participate in metal coordination. On the other hand, the reaction of HBMDP with 2 equiv each of copper(II) ion and acetate in methanol produces the binuclear copper complex [Cu(2)BMDP(OAc)](ClO4)(2) . 2H(2)O, which crystallizes in the monoclinic space group C2/m with unit cell dimensions a = 19.934(4) Angstrom, b = 23.460(9) Angstrom, c = 20.039(4) Angstrom, and beta = 110.65(2)degrees. A single-crystal X-ray structure reveals that the two copper ions are coordinated to the aromatic and aliphatic nitrogens as well as being bridged by the acetate anion and the alkoxide oxygen of the ligand. As a result of the inherent asymmetry of the ligand, one copper ion is five-coordinate (distorted trigonal bipyramidal) while the other copper ion is four-coordinate (distorted square planar). The crystal structure also reveals that in the solid state an oxygen from one of the perchlorate counterions is weakly bound to the four-coordinate copper (similar to 2.6 Angstrom), suggesting that a vacant coordination site exists at this formally four-coordinate copper center. The potential for site-directed reactivity at this lower coordinated copper center was demonstrated by adding 0.5 equiv of azide ion to the binuclear copper complex in acetonitrile. The resulting azido-bridged complex, {[Cu(2)BMDP(OAc)]N-2(3)}(ClO4)(3) . 8.5H(2)O, crystallizes in the orthorhombic space group Cmca with unit cell dimensions a = 22.603(3) Angstrom, b = 19.565(3) Angstrom, and c = 36.965(3) Angstrom. A single-crystal X-ray structure shows that the two copper ions within the binuclear unit; are still coordinated by the ligand nitrogens, the acetate, and the ligand alkoxy oxygen. In addition, the copper ion that was four-coordinate in the binuclear complex is now bridged by azide to its companion four-coordinate copper in a separate binuclear unit. As a result, both coppers within the binuclear unit are now five-coordinate, one remaining distorted trigonal bipyramidal while the other adopts square pyramidal geometry. In this reaction, azide specifically fills the vacant coordination site of the four-coordinate copper ion in the binuclear complex. Although these two binuclear paramagnetic copper(II) complexes are magnetically weakly coupled, their H-1 NMR spectra show relatively sharp lines that provide solution assignments consistent with the solid state structures.
To our knowledge this is the first example of a binuclear copper complex to exhibit both coordination number asymmetry and directed reactivity at one metal center by virtue of ligand design.

AB The interactions formed in solution between the bent lanthanide metallocene Cp*Yb-2 (1) and cis-P(2)PtX(2) complexes (P-2 = a chelating phosphine; X = H, CH3) have been investigated using NMR spectroscopy. 1 has been found to form a significant interaction with the cis dihydride complexes [(Cy)(2)P(CH2),P(Cy)(2)]PtH2 (n = 2, dcype, 4; n = 3, dcypp, 6). Intermolecular exchange is slow on the NMR time scale for a 1:1 sample of 1 and 4, and there are significant perturbations in the spectral values from those of free 4. Additionally, (1)J(YbH) Of 180 HZ and J(PtYb) of 2260 Hz are present. A sample of 1 and 6 gives almost identical spectra values. Fast intermolecular exchange (NMR) occurs for samples containing an excess of the dihydride complexes but not for samples containing an excess of 1. The NMR values of a 1:1 sample of the dimethyl complex (dippe)Pt(CH3)2 (dippe = (Pr-i)(2)P(CH2)2P(Pr-i)2) (8) and 1 are perturbed from the analogous values for free 8, but fast intermolecular exchange is present on the NMR time scale down to -90 degrees C. The solid-state structure of this adduct, 9, shows a rare mode of an agostic bridging methyl interaction; however, (1)J(CH3) is unchanged from that of 8. Crystal data for 9: monoclinic, space group C2/c, with a = 33.90(2) Angstrom, b = 11.255(6) Angstrom, c = 20.535(6) Angstrom, beta = 98.41(4)degrees, V = 7750(7) Angstrom(3), Z = 8, final R = 0.029 for 361 variables, and 3300 data with I > 3 sigma(I). A 1:1 sample of 1 and a methyl hydride complex, (dippe)Pt(CH3)-(H)(10) undergoes slow exchange in solution, with (1)J(ybH) of 168 Hz and J(PtYb) of 960 Hz. Again (I)J(CH3) is unchanged from that of free 10. The Yb-CH3 interaction likely arises from geometrical constraints, the Yb-hydride interaction holding the Yb center near the methyl group. The solid-state structure of this adduct, 11, shows an asymmetric (u-CH3)(u-H) bridge. Cystal data for 11: monoclinic, space group P2(1)/c, with a = 18.778(5) Angstrom, b = 10.903(4) Angstrom, c = 20.255(5) Angstrom, beta = 114.74(2)degrees, V = 3766(2) Angstrom(3), Z = 4, final R = 0.069 for 327 variables, and 4694 data with I > 3 sigma(I). The NMR perturbations and coupling constants resulting from the interactions of 1 with the P(2)PtX(2) complexes are discussed in detail and correlated with the solid-state structures. The Pt-195 and Yb-171 chemical shifts of 1, the Pt(II) complexes, and the 1:1 adducts are also reported.

AB The synthesis and characterization of p-HS(CH2)(11)OC6H4N=NC6H5, compound 1d, is reported. Compound 1d self-assembles onto Au(111) substrates into highly ordered monolayer films. Self-assembled monolayer films (SAMs) of 1d on Au(111)/mica have been characterized by ellipsometry, surface-enhanced Raman spectroscopy (SERS), and atomic force microscopy (AFM). We also report the characterization of SAMs of 1d on bulk single crystal Au(111) by synchrotron in-plane X-ray diffraction (XRD) measurements. AFM and in-plane XRD suggest that a SAM of 1d is comprised of domains of 1d which form a hexagonal lattice (4.50 +/- 0.06 Angstrom nearest neighbor spacing) that is incommensurate with the underlying Au(111) lattice. A model is proposed to describe the SAM structure. In such a model, small bundles (similar to 80 molecules) of ordered azobenzene moieties that rest over a set of inward tilting alkyl surface tethering groups make up the individual domains. The ''bundle model'' for a SAM of 1d on Au(111) is a new one and provides insight into the way adsorbate molecules may arrange themselves in these novel materials. Thermal annealing of the as-deposited SAM of 1d results in a modest increase in domain size from similar to 45 to similar to 55 Angstrom and a change in azobenzene tilt angle from 20-30 degrees to approximately 0 degrees with no change in nearest neighbor spacing. The redox activity of the azobenzene group is significantly affected by monolayer film structure. Only 2% of the azobenzene groups within a SAM of 1d are electrochemically accessible through cyclic voltammetry in a THF/0.1 M n-Bu(4)NPF(6) electrolyte. The monolayer structure impedes the incorporation of charge compensating ions into the film, thereby regulating the electrochemical accessibility of the azobenzene redox centers within the film. Submonolayer films of 1d and films prepared by the coadsorption of 1d with ethanethiol on Au(111)/mica have greater electrochemical accessibilities with regard to the azobenzene groups that do pure SAMs of 1d. Interfacial capacitance measurements and film penetration studies with Fe(CN)(6)(3-) show that SAMs of 1d are densely packed structures which form impenetrable barriers to Fe(CN)(6)(3-).

AB Epidemiological evidence indicates that avoidance of smoking, increased consumption of fruits and vegetables, and control of infections will have a major effect on reducing rates of cancer, Other factors include avoidance of intense sun exposure, increases in physical activity, and reduction of alcohol consumption and possibly red meat, A substantial reduction in breast cancer is likely to require modification of ses hormone levels, and development of practical methods for doing so is a high research priority, Resolution of the potential protective roles of specific antioxidants and other constituents of fruits and vegetables deserves major attention, Mechanistic studies of carcinogenesis indicate an important role of endogenous oxidative damage to DNA that is balanced by elaborate defense and repair processes, Also key is the rate of cell division, which is influenced by hormones, growth, cytotoxicity, and inflammation, as this determines the probability of converting DNA lesions to mutations, These mechanisms may underlie many epidemiologic observations.

AB CLN3 has been mapped genetically to 16p12, to the interval between D16S288 and D16S383, a sex-averaged genetic distance of 2.1 cM, Analysis of disease haplotypes for four microsatellite markers in this interval, D16S288, D16S299, D16S298, and SPN, has shown significant allelic association between one allele at each of these loci and CLN3. Ah four of the associated markers were used as nucleation sites in the isolation of genomic clones (YACs), A contig was assembled which contains 3 of the 4 associated markers and which confirmed the relative order of these markers, Marker D16S272 has been located on the physical map between D16S288 and D16S299. Restriction mapping has demonstrated the location of possible CpG islands. One gene, STP, has been localised on the YAC contig proximal to D16S298 and is therefore a candidate for CLN3, Other genes, including IL4R, SGLT2, and UQCRC2, have been excluded from this region.

AB In order to identify genes originating from the Batten disease candidate region, we have used the technique of exon amplification to identify transcribed sequences, This procedure produces trapped exon clones, which can represent single exons or multiple exons spliced together and is an efficient method for obtaining probes for physical mapping and for screening cDNA libraries, The source of DNA for these experiments was a collection of chromosome 16 cosmid contigs isolated by the direct subcloning of region-specific yeast artificial chromosomes (YACs) and hybridization of inter-alu PCR products from these YACs to the flow-sorted Los Alamos chromosome 16 cosmid library. We are now using the resulting exon probes to screen retina and brain cDNA libraries for candidate JNCL genes. (C) 1995 Wiley-Liss, Inc.

AB Batten disease (juvenile-onset neuronal ceroid lipofuscinosis; JNCL) is an autosomal recessive neurodegenerative disorder, characterized by the cytosomal accumulation of autofluorescent proteolipopigments in neurons and other cell types, The Batten disease gene (CLN3) has not yet been identified, but has been mapped to a small region of human chromosome area 16p12.1-p11.2. We recently reported the fortuitous discovery that the cytosolic phenol sulfotransferase gene (STP) is located within this same interval of chromosome 16p, Since phenol sulfotransferase is expressed in neurons, can sulfate lipophilic phenolic compounds, and is mapped near CLN3, STP is considered as a candidate gene for Batten disease, YAC and cosmid cloning results have further substantiated the close proximity of STP and a highly related sulfotransferase (STM), encoding the catecholamine-preferring enzyme, to the CLN3 region of chromosome 16p, In this report, we summarize some of the recent progress in the identification of two phenol sulfotransferase genes (STP and STM) as positional candidate genes for Batten disease.

AB A new approach to quantum dynamics is presented which addresses the fundamental difficulty of exponential growth of computational complexity with the dimensionality of the system. A general recursive polynomial treatment of the time-independent full Green operator, the average-case complexity approach to multi-dimensional integration, and the continuous distributed approximating functional representation of the Hamiltonian are the three ingredients of the approach. Calculations for collinear H + H-2 reactive scattering are presented to illustrate the method.

AB A procedure is presented for accelerating the convergence of the polynomial-expanded spectral density method for calculating eigenvalues and eigenvectors of a Hamiltonian. After a relatively small number of terms in the expansion, one calculates the scalar spectral function, whose plot gives information on the distribution of the eigenvalues contained in the initial wavepacket. The vectors produced by H acting on the initial vector, combined with the energy-dependent coefficients, are used to construct 'purified' and 'neighborhood basis vectors', which are used to restart the expansion and to diagonalize the Hamiltonian.

AB Because proteases free in the body are damaging to the tissues, animals have evolved various agents for their inactivation and clearance. Mammals, for instance, have a diverse array of active site protease inhibitors in the plasma, in addition, mammals have alpha(2)-macroglobulin (alpha(2)M), which binds active proteases, and the alpha(2)M-protease complex is then cleared from the plasma by a receptor-mediated endocytotic process. (alpha(2)M is also present in the plasma of many invertebrates, and in the American horseshoe crab, Limulus polyphemus, it is the only protease inhibitor in the plasma. To search for a clearance process for proteases in Limulus, fluerescein isothiocyanate (FITC)-labeled proteins were injected into the blood, and the fluorescence in the plasma and associated with the blood cells was determined. FITC-labeled trypsin was cleared with an initial mixing period (0-10 min) and a rapid clearance period (10-30 min), followed by the reappearance of FITC in the plasma (45-90 min). Before and during the clearance process, the labeled trypsin was associated with a complex having a molecular mass identical to that of Limubus alpha(2)M, and that was precipitated by antibodies directed against Limubus alpha(2)M. The fluoresceinated material that reappeared in the plasma after 45 min was of low molecular mass (<10 kDa) and thus appears to have experienced degradation. The clearance of trypsin requires its protease activity, since phenylmethylsulfonyl fluoride-inactivated, FITC-labeled trypsin was cleared only very slowly if at all (t1/2 > 180 min). FITC-labeled, trypsin-reacted Limubus alpha(2)M was cleared rapidly from the plasma of Limubus, whereas FITC-labeled, native Limubus alpha(2)M persisted undiminished in excess of 400 min. The blood cells of Limubus bound FITC-labeled trypsin-reacted Limubus alpha(2)M, and the peak of recovery from the blood cells coincided with the minimum concentration of FITC-labeled protein in the plasma, suggesting that the blood cells participate in the clearance of alpha(2)M-protease complex from the plasma. Thus, we have demonstrated the existence of a clearance pathway in Limubus that operates selectively on enzymatically active proteases and have shown that Limulus alpha(2)M is the probable agent for protease clearance. This is the first documentation of a protease clearance pathway in invertebrates and represents the first identified physiological function for alpha(2)M in invertebrates.

Both intermediates are distinct from the enzyme-substrate and enzyme-product complexes. Mutation of key catalytic residues changed the rate determining steps so that protein and substrate intermediates within the overall reaction pathway could be visualized.

AB Accurate terrestrial glacial chronologies are needed for comparison with the marine record to establish the dynamics of global climate change during transitions from glacial to interglacial regimes. Cosmogenic beryllium-10 measurements in the Wind River Range indicate that the last glacial maximum (marine oxygen isotope stage 2) was achieved there by 21,700 +/- 700 beryllium-10 years and lasted 5900 years. Ages of a sequence of recessional moraines and striated bedrock surfaces show that the initial deglaciation was rapid and that the entire glacial system retreated 33 kilometers to the cirque basin by 12,100 +/- 500 beryllium-10 years.

ID PARTIAL DISLOCATIONS; SILICON; SLIP
AB A step-wise nucleation and growth mechanism based on the coincidence site lattice (CSL) theory is proposed for deformation twinning in h.c.p. structures. Lattice transformation during twinning is accomplished by a coordinated movement of a large number of atoms between two lattice match planes from the matrix to twin positions rather than a layer by layer movement through twinning dislocations as proposed for twinning dislocation theories. The sidewise propagation and thickening of a twin lamella proceeds in a step-wise manner with lattice match planes being the coherent boundaries between the matrix and twins. This model predicts that twinning in h.c.p. lattices can occur at a high velocity close to the sound speed, which is impossible according to twinning dislocation theories. The proposed mechanism is also consistent with other observations such as lack of critical-resolved-shear-stress for twinning, emissary dislocations, and insensitivity to temperature. Dislocation reactions may be involved in twinning although they are, at high stresses, not required.

AB A TEM study of mechanical twinning in Ti and Zr was performed. A large number of [0001]-dislocations which are rarely seen in the matrix, and a new type of stacking fault were found within deformation twins in both materials. Matrix dislocations were observed to actively interact with the tips of twin embryos and step ledges of growing twin lamellae. Twin embryos bounded by straight coherent and inclined semi-coherent boundaries were observed. These results as well as the morphological variation of twin lamellae during deformation do not agree with twinning dislocation theories but support a step-wise nucleation and growth mechanism proposed for deformation twinning in h.c.p. structures. Extended discussions are provided to address unanswered questions in the literature concerning deformation twinning.

AB Steady-state creep experiments have been performed on polycrystalline YBa2Cu3Ox in the temperature range of 850-970 degrees C, as a function of oxygen partial pressure (P-O2). The results, when combined with a reanalysis of previous deformation studies, indicate that contrary to the previous conclusion that the activation energy was a function of P-O2, there are two different temperature regimes characterized by P-O2-independent activation energies of 675 and 1100 kJ/mol for low and high temperatures, respectively. This is interpreted in terms of two independently operating rate-controlling mechanisms: grain-boundary diffusion and lattice diffusion. Diffusion coefficients have been derived by comparing experimental data and theoretical models.

AB We examined the effects of replacing dietary fat with carbohydrates on high-density-lipoprotein (HDL) subclasses as measured by nondenaturing polyacrylamide-gradient-gel electrophoresis. One hundred five men received a 6-wk low-fat diet (24% of total energy) and a 6-wk high-fat diet (46% of energy) in a crossover design. Absorbency of protein stain was measured within five HDL subclasses: HDL(3c) (7.2-7.8 nm), HDL(3b) (7.8-8.2 nm), HDL(3a) (8.2-8.9 nm), HDL(2a) (8.8-9.7 nm), and HDL(2b) (9.7-12 nm). The low-density-lipoprotein-(LDL) subclass pattern was determined by gradient-gel electrophoresis, with pattern B men defined as having an LDL-predominant peak diameter less than or equal to 25.5 mn and an LDL distribution skewed toward larger size particles. On the high-fat diet, 18 men exhibited LDL-subclass pattern B and 87 men exhibited the alternative LDL pattern A. Twelve men had the apolipoprotein (apo) epsilon 2. allele. Replacing dietary fat with carbohydrates 1) significantly decreased HDL(3a), HDL(2a), and HDL(2b); 2) reduced HDL(2b) significantly more in pattern A than in pattern B men; and 3) increased plasma HDL(3b), concentrations significantly more in those men with the epsilon 2 allele. Our results suggest that unfavorable HDL changes were significantly more Likely to occur in men who had LDL-subclass pattern A or the apo epsilon 2 allele than in men who had pattern B or lacked the epsilon 2 allele.

AB Population-rate equations are analytically solved for constant pump rates. Conditions for population inversions are developed for this simplified case. Numbers appropriate for inner-shell photo-ionization of magnesium and neon are used. These allow back-of-the envelope calculations for predicting lasing duration. Pump-rate thresholds are also given which permit lasing for the duration of the pumping. Blackbody-source temperatures associated with such pump rates are calculated. A method of using the solution of the small-signal population-rate equations to determine the saturated intensity when the lower lasing level has a decay channel is given. This method is applied to the case of constant pump rates. An analytic expression for the saturated intensity is developed for this case.

AB A procedure that uses extended X-ray absorption fine structure (EXAFS) spectroscopy for quantitative chromium(III) speciation in neat solid mixtures is described. The procedure uses the full, filtered EXAFS, e.g., 4 less than or equal to k less than or equal to 12 Angstrom(-1), rather than the smaller k-range associated with a single coordination sphere. Concentration is determined by a simple correlation of full, filtered EXAFS of standards with full, filtered EXAFS of mixtures. Under optimized conditions, calibration curves for mixtures of Cr2O3 and Cr(NO3)(3) . 9H(2)O have slopes of 1.002, respective intercepts of -0.7% and 0.5%, and correlation coefficients of 0.9991. Fluorescence EXAFS from mixtures must be compared to fluorescence EXAFS from standards, and the matrices and thicknesses of standards and mixtures must be closely matched. Transmission EXAFS of standards must be obtained to correct for self-absorption effects.

AB Despite the rapid growth in the use of imaging detectors in spectroscopy, the charge-injection device (CID) has unique features that have not been fully exploited. The advantages of the CID as a two-dimensional array detector for laser-induced fluorescence detection in highly multiplexed capillary electrophoresis are evaluated. In such a system, the CID maintains both high sensitivity and high sampling rate, which are usually difficult to achieve simultaneously with other array detectors. Applying the electronic windowing function significantly improves the scan rate and greatly reduces the volume of data generated. With 1-s exposure time and 488-nm excitation, the detection limit of the system is 10(-12) M fluorescein with the device cryogenically cooled and 10(-11) M fluorescein at ambient temperature. The low dark current of the CID imager allows operation at room temperature without significantly affecting sensitivity when combined with moderate laser powers. We demonstrate that the CID is well suited for high-speed, high-throughput DNA sequencing based on multiplexed capillary electrophoresis with on-column laser-induced fluorescence detection.

DT Article
ID SUPERCONDUCTORS
AB Two assemblies of Pb-BSCCO 2223 superconductor bars were produced for use in ac connections between utility system lines at room temperature and a fault-current limiter operating at 4 K. Each assembly consisting of four parallel bars arranged within a IDD mm-diameter boundary, delivered 1500 A (peak), 50-60 Hz ac through the 77-4 K range of the temperature gradient while dissipating < 0.3 W. The sinter-forged bars displayed dc critical current densities of 950-1300 A cm(-2) at 77 K and > 5000 A cm(-2) at 4 K; magnetic field sensitivity was relatively small. Although thermal conductivity tests showed values much higher than those found in the literature for polycrystalline Pb-BSCCO 2223 made by other processes, this undesirable result was counterbalanced by the relatively high values of critical current, which enabled the use of bars with smaller cross-sectional areas. Typical 50-Hz ac power losses at 77 K in each bar (with a cross-sectional area of 0.54 cm(2)) were 1 mW cm(-1) of length at 310 A and 1.75 mW cm(-1) at 375 A. Losses were much smaller at 4 K. Bars were 25 cm long, including ends that carried silver contacts sinter forged to the ceramic, with a 21 cm silver-free length in the thermal gradient between the fixed-temperature terminals. Thermal efficiency of the assemblies was assessed by helium boiloff tests.

DT Article
AB The preparation and surface science study of a magnesium chloride/titanium chloride system, grown in the form of a thin film on an inert substrate under ultra-high vacuum conditions is reported. The aim of the authors is to build a model catalyst for the Ziegler-Natta polymerization of ethylene and propylene. Magnesium chloride and titanium chloride are deposited on a gold polycrystalline foil from the gas phase. The deposited films are characterized by AES, TPD of n-C6H14 and film sublimation. Auger uptake experiments show that the MgCl2 film grows by a layer-by-layer mechanism on the polycrystalline substrate. The deposition of MgCl2 on the Au substrate can be followed by TPD of n-C6H14 up to the completion of the first monolayer. It is not possible to grow TiCl4 films on a MgCl2 film at room temperature, because of its high vapor pressure. The chemical interaction of TiCl4 with an ordered MgCl2 surface is too weak to allow the growth of a TiCl4 monolayer around 300 K. The bombardment of the MgCl2 thin film with Ar ions did not produce a surface capable to adsorb TiCl4 at room temperature.

AB Background: The purposes of this study were to investigate the pharmacokinetics of methylphenidate hydrochloride (Ritalin) in the human brain, to compare them with those of cocaine, and to evaluate whether cocaine and methylphenidate compete for the same binding sites.
Methods: We used positron emission tomography to measure the temporal and spatial distribution of carbon 11 (C-11)-labeled methylphenidate. These results were compared with those obtained previously for [C-11]cocaine. Eight healthy male subjects, 20 to 51 years of age, were scanned with [C-11]methylphenidate. Three were tested twice to assess test-retest variability, four were tested at baseline and after administration of methylphenidate, and one was tested with [C-11]methylphenidate and [C-11]cocaine. Two baboons were scanned to evaluate whether there was competition between cocaine and methylphenidate for the same binding sites in the brain.
Results: The uptake of [C-11] methylphenidate in the brain was high (mean+/-SD, 7.5%+/-1.5%), and the maximal concentration occurred in striatum. Pretreatment with methylphenidate decreased binding only in striatum (40%). Although the regional distribution of [C-11]methylphenidate was identical to that of [C-11] cocaine and they competed with each other for the same binding sites, these two drugs differed markedly in their pharmacokinetics, Clearance of [C-11]methylphenidate from striatum (90 minutes) was significantly slower than that of [C-11]cocaine (20 minutes). For both drugs, their fast uptake in striatum paralleled the experience of the ''high.'' For methylphenidate, the high decreased very rapidly despite significant binding of the drug in the brain. In contrast, for cocaine, the decline in the high paralleled its fast rate of clearance from the brain.
Conclusion: We speculate that because the experience of the high is associated with the fast uptake of cocaine and methylphenidate in the brain, the slow clearance of methylphenidate from the brain may serve as a limiting factor in promoting its frequent self-administration.

AB We study the effects of peculiar velocities on statistical measures of galaxy clustering. These effects occur when distances to the galaxies are estimated from their redshifts. It is assumed that the clustering pattern results from the gravitational instability of initially Gaussian, small-amplitude perturbations of a Friedman-Lemaitre cosmological model. Explicit expressions are given for an arbitrary density parameter Omega of the model, both when the cosmological constant, Lambda, is zero, and when the model is spatially flat, Omega + Lambda/3H(2) = 1.
Kaiser (1987) had analyzed the redshift distortion of the two-point correlation function. This function determines the variance of the density field distribution function and can be computed using linear perturbation theory. We show here how to compute higher order moments in redshift space, paying special attention to the skewness, or third moment of the density field, and its Fourier space counterpart, the bispectrum. This calls for a weakly non-linear analysis.
We rely on a perturbative expansion of particle trajectories in Lagrangian coordinates, using the formalism introduced by Moutarde et al. (1991) and further developed by Bouchet et al. (1992, 1994). This formalism extends to higher orders the Zel'dovich first order (i.e, linear) solution (1970). The lowest non-vanishing contribution to the skewness comes from the first and second-order terms in perturbation theory. Therefore, using Zel'dovich approximation would not be self-consistent and would yield inaccurate results. We show that a physically consistent and quantitatively accurate analysis of the growth skewness in redshift space can be obtained from second-order Lagrangian theory.
With practical applications to redshift surveys in mind, we also study the effects of spatial smoothing of the evolved density field. The necessary formalism was developed by Juszkiewicz and Bouchet (1991) and Juszkiewicz et al. (1993a). Here we give the first complete account of these calculations; we also extend the formalism by explicitly taking redshift distortions into account. We give analytic expressions for the gravitationally induced skewness as a function of the power spectrum and of Omega, for a spherical top-hat and a Gaussian smoothing filter.
We compare our analytical predictions with measurements performed in numerical simulations, and find good agreement. These results should then prove useful in analyzing large scale redshift surveys. In particular, our results, in conjunction with the recent suggestion of Fry (1994), may solve a well known problem which always arises in conventional dynamical determinations of the mean density of the universe. Such studies produce estimates of Omega which are coupled with the parameters describing the bias in the galaxy distribution. As a result, a biased Omega = 1 model is dynamically indistinguishable from an open, unbiased, one. For the first time, it may become possible to break this degeneracy, and decouple the estimates of linear and non-linear bias from the estimates of Omega and Lambda.

AB We have imaged the edge-on starburst galaxy NGC 2146 with the Position Sensitive Proportional Counter (PSPC) and the High Resolution Imager (HRI) on board ROSAT and have compared these data to optical images and long-slit spectra. NGC 2146 possesses a very large X-ray nebula with a half-light radius of 1' (4 kpc) and a maximum diameter of similar to 4', or 17 kpc. The X-ray emission is resolved by the PSPC and preferentially oriented along the minor axis, with a total flux of 1.1 x 10(-12) ergs cm(-2) s(-1) over 0.2-2.4 keV and a luminosity of similar to 3 x 10(40) ergs s(-1). The inner X-ray nebula is reserved by the HRI into at least four bright knots together with strong diffuse emission responsible for at least 50% of the flux within a radius of 0'.5 (similar to 2 kpc). The brightest knot has a luminosity of (2-3) x 10(39) ergs s(-1). The X-ray nebula has a spatial extent much larger than the starburst ridge seen at centimeter wavelengths by Kronberg and Biermann (1981) and is oriented in a ''X-like'' pattern along the galaxy minor axis at a position angle of similar to 30 degrees. This minor-axis X-ray emission is associated with a region of Ha and dust filaments seen in optical images. Optical spectra show that the emission-line gas along the minor axis is characterized by relatively broad lines (similar to 250 km s(-1) FWHM) and by ''shocklike'' emission-line flux ratios. Together with the blue-asymmetric nuclear emission-line and NaD interstellar absorption-line profiles, these optical data strongly suggest the presence of a starburst-driven superwind. The X-ray spectrum extracted from the central 5' contains a strong Fe L emission-line complex at 0.6-1.0 keV and a hard excess above 1.0 keV. The spectrum is best described with a two-component model, containing a soft (kT similar to 400-500 eV) Raymond-Smith thermal plasma together with either a Gamma = 1.7 power-law or a kT > 2.2 keV bremsstrahlung component. The soft thermal component provides similar to 30% of the total luminosity over 0.2-2.4 keV, or similar to 10(40) ergs s(-1). The pressure derived from the soft component of the X-ray spectrum is consistent with that predicted from a starburst-driven superwind if the filling factor of the warm gas is similar to 1%-10%. If the hard X-ray component is thermal gas associated with the galactic outflow, the filling factor must be close to unity. Predictions of the luminosity, temperature, and size of an adiabatic starburst-generated windblown bubble are consistent with those measured for the soft thermal X-ray emission in NGC 2146. The hard X-ray component, however, has a luminosity much larger than predicted by the superwind model if this component is thermal emission from gas heated by an internal shock in the expanding bubble. We briefly review various possibilities as to the nature of the hard X-ray component in NGC 2146.

AB We report the detection of an unusual high-energy transient by the gamma-ray burst detectors onboard the satellite Ginga. This event was much softer than classical gamma-ray bursts, with a spectrum that peaks between 16 and 18 keV and decreases both above and below the peak. A thermal bremsstrahlung fit to the 20-400 keV emission gives a characteristic temperature of approximate to 24 keV; much softer (cooler) than the greater than 100 keV temperatures characteristic of the classical gamma-ray bursts, but similar to that of the soft gamma-ray repeaters (SGRs). The spectrum above the peak is similar to that of type I X-ray bursts; however, the peak energy is higher by about a factor of 5, well above the Eddington limit. We have established with high confidence that the spectrum rolls over below 15 keV. Spectral models which include photoelectric absorption from neutral matter with column densities of approximate to 10(24) cm(-2) give acceptable fits to the low-energy rollover, as does a power-law fit with an index alpha approximate to -2.5. power-law models with indices greater than -1.5 are strongly rejected by the data (a Rayleigh-Jeans spectrum has index -1.0). The time history of the event is simple, with a rise time of approximate to 0.7 s followed by an exponential decay with a 3 s timescale, similar to those seen from type I X-ray bursts as well as some classical gamma-ray bursts, but somewhat unusual for a SGR.

TI EFFECTS OF HEAVY-METALS ON ASTROPHYSICAL OPACITIES
SO ASTROPHYSICAL JOURNAL
LA English
DT Article
DE ATOMIC PROCESSES; STARS, INTERIOR
AB Recent reexaminations of astrophysical opacities resulted in large opacity increases. The increases were mostly due to improvements in the atomic physics used in the calculations; in particular, the treatment of bound-bound transitions of partially ionized Fe. The new opacities were also found to depend on other Fe group elements even though in typical stars these elements have a combined abundance that is more than an order of magnitude lower than Fe. It is, therefore, important to examine the contributions from even heavier elements. These elements are much lower in abundance still, but have many more bound electrons and could, in principle, impact astrophysical opacities. It is shown that although the heavy elements are stronger photon absorbers their small abundance leads to a marginal effect on the Rosseland mean opacities of stars with solar metal distributions.

AB The unusual variable star AM CVn has puzzled astronomers for over 40 years. This object, both a photometric and spectroscopic variable, is believed to contain a pair of hydrogen-deficient white dwarfs of extreme mass ratio, transferring material via an accretion disk. We examine the photometric properties of AM CVn, analyzing 289 hours of high-speed photometric data spanning 1976 to 1992. The power spectrum displays significant peaks at 988.7, 1248.8, 1902.5, 2853.8, 3805.2, 4756.5, and 5707.8 mu Hz (1011.4, 800.8, 525.6, 350.4, 262.8, 210.2, and 175.2 s). We find no detectable power at 951.3 mu Hz (1051 s), the previously reported main frequency. The 1902.5, 2853.9, and 3805.2 mu Hz peaks are multiplets, with frequency splitting in each case of 20.77 +/- 0.05 mu Hz. The 1902.5 mu Hz seasonal pulse shapes are identical, within measurement noise, and maintain the same amplitude and phase as a function of color. We have determined the dominant frequency to be 1902.509802 +/- 0.00001 mu Hz, with P = +1.71 (+/-0.04) x 10(-11) s s(-1). We discuss the implications of these findings on a model for AM CVn.

We intend to provide a theoretical scenario to be compared with the new homogeneous, accurate, and large photometric databases on light and temperature curves of radial pulsators (MACHO, EROS, and OGLE) which are becoming available.
The nonlinear and convective models investigated in this survey present five different types of instability. The location of the transition lines which separate regions of different modal stability inside the instability strip (IS) were thoroughly evaluated. An observational test on the appearance of first-overtone pulsators among BL Herculis stars based on the topology of the instability regions outlined in the present investigation was also suggested.

AB Using the output from a grid of 60 Type II supernova models (Woosley and Weaver 1995) of varying mass (11 less than or equal to M/M. less than or equal to 40) and metallicity (0, 10(-4), 0.01, 0.1, and 1 Z.), the chemical evolution of 76 stable isotopes, from hydrogen to zinc, is calculated. The chemical evolution calculation employs a simple dynamical model for the Galaxy (infall with a 4 Gyr e-folding timescale onto an exponential disk and 1/r(2) bulge), and standard evolution parameters, such as a Salpeter initial mass function and a quadratic Schmidt star formation rate. The theoretical results are compared in detail with observed stellar abundances in stars with metallicities in the range -3.0 less than or equal to [Fe/K] less than or equal to 0.0 dex. While our discussion focuses on the solar neighborhood where there are the most observations, the supernova rates, an intrinsically Galactic quantity, are also discussed.
Sampling 4.6 Gyr ago at a distance of 8.5 kpc, we find a composition at the solar circle that is in excellent agreement with the solar abundances from hydrogen to zinc. Type Ia supernovae provide about one-third of solar iron abundance in this distribution. Oxygen comes from the massive stars, but carbon and nitrogen come chiefly from stars with M less than or equal to 8 M.. The light metal and iron group elements, with the exception of titanium, are in generally good agreement with the stellar abundance data. We also find an age-metallicity relation, a G dwarf distribution, and present-day supernova rates that are in satisfactory agreement with observations. The neutrino process provides a good explanation for the origin of B-11 and F-19 and the increase in Li-7 over its canonical homogeneous big bang value. In order to explain the observed helium-to-metal enrichment (Delta Y/Delta Z similar or equal to 4), we find a favored cutoff in the mass of supernovae that eject all material external to the iron core of about 30 M., but this limit may be increased by considering the effects of mass loss. The robustness of the results to variations in the iron yields of the Type II supernova models are examined.

AB A pilot network of three U.S. sites was initiated to test the feasibility of quantitating arsenic, cadmium copper, manganese, lead, and zinc in wet deposition, and to make recommendations for a subnetwork at site and training levels compatible with other wet deposition networks, specifically National Atmospheric Deposition Program (NADP). Modifications were made to Aerochem Metric samplers, including use of Teflon(R) surfaces, an insulated enclosure, and a thermostat controlled cooling fan and heater. Inductively coupled plasma mass spectrometry (ICP-MS) is well suited for the routine determination of the targeted metals at the low mu g l(-1) concentrations. Relatively simple cleaning and handling protocols are suitable for measuring metal concentrations at continental levels in precipitation without introducing significant contamination.

AB A number of actions have been undertaken within the National Atmospheric Deposition Program (NADP) to implement a regional mercury deposition network. This paper describes a field test designed to evaluate a collector design and protocol for implementation within a new Hg network. The collector chosen for evaluation is a ''dual-orifice'' collector, designed to sample precipitation for mercury and other metals simultaneously. The method chosen for Hg analysis was cold vapour atomic fluorescence spectroscopy (CVAFS). The weekly precipitation Hg concentrations range between 4.29 and 17.88 ng l(-1), with a volume-weighted mean of 10 ng l(-1) comparable to those reported in other ongoing studies in North America and Europe. Calculated deposition flux ranges from 43 to 358 ng m(-2) week(-1), with a mean of 186 ng m(-2) week(-1).

AB Light-dependent reduction of cystine disulfide bonds results in activation of several of the enzymes of photosynthetic carbon metabolism within the chloroplast. We have modeled the tertiary structure of four of these light-activated enzymes, namely NADP-linked malate dehydrogenase, glyceraldehyde-3-P dehydrogenase, fructosebisphosphatase, and sedoheptulosebisphosphatase, and identified cysteines in each enzyme that might be expected to form inactivating disulfide bonds (Li, D., F. J. Stevens, M. Schiffer, and L. E. Anderson, 1994. Biophys. J. 67:29-35). We have now converted two residues in the Escherichia coli NAD-linked malate dehydrogenase to cysteines and produced a redox-sensitive enzyme. Oxidation of domain-locking cysteine residues in the mutant enzyme clearly mimics dark inactivation of the redox-sensitive chloroplast dehydrogenase. This result is completely consistent with our proposed mechanism.

AB We introduce the use of microfabrication techniques to construct on a silicon wafer a synthetic capillary bed with 2.5- to 4-micron (mu)-wide channels. Establishment of a fluid pressure gradient allowed us to observe simultaneously using optical microscopy hundreds of cells flowing through the bed at physiological speeds. We find a large distribution of mobilities among red cells flowing through the structure; smaller channels provide a greater impedance to flow than larger ones, indicating that kinetic drag variations provide the origin of the distribution. The mobility of a particular cell is not correlated with the cell diameter but appears to be inversely correlated with intracellular calcium concentration of the cell, as determined by fluorescence of the calcium-binding dye fluo-3 AM. Also, we are able to use the parallel processing nature of our arrays to observe isolated events where the rigidity of the red cell seems to change suddenly over several orders of magnitude as it blocks a channel in the array.

ID PERIOD
AB We show that electromagnetic (em) seismometers may be easily and accurately calibrated by removing a step of current from their signal coil, and simultaneously switching the signal coil to a recorder to capture the response. A theory is developed that obtains the damped generator constant, resonant frequency, and damping ratio from the output of a system identifier used to analyze the response. Only the seismometer mass (from the manufacturer) and the applied current (measured) need be known for a complete calibration. The coil and damping resistances are not required. The method is confirmed by comparing this signal-coil method with weight-lift and calibration-coil calibrations. For a GS-13 V seismometer, these results were within 1.3% of each other. The undamped generator constant computed from the damped generator constant obtained by the signal-coil method matched the generator constant given by the manufacturer to better than 1%. Calibration of nine new L-4C components resulted in undamped generator constants all within 3% of the values given by the manufacturer. The circuit used in the signal-coil method is shown and explained.

AB Quantitative analysis of chlorophyll fluorescence transients and quenching has evolved rapidly in the last decade. Instrumentation capable of fluorescence detection in bright actinic light has been used in conjunction with gas exchange analysis to build an empirical foundation relating quenching parameters to photosynthetic electron transport, the state of the photoapparatus, and carbon fixation. We have developed several instruments that collect video images of chlorophyll fluorescence. Digitized versions of these images can be manipulated as numerical data arrays, supporting generation of quenching maps that represent the spatial distribution of photosynthetic activity in leaves. We have applied this technology to analysis of fluorescence quenching during application of stress hormones, herbicides, and physical stresses, including drought and sudden changes in humidity of the atmosphere surrounding leaves, and during stomatal oscillations in high CO2 We describe a recently completed portable fluorescence imaging system utilizing LED illumination and a consumer-grade camcorder, that will be used in long-term, nondestructive field studies of plant virus infections.

AB Mallards (Anas platyrhynchos, n = 289) wintering in the Southern High Plains of Texas were collected from 15 October 1988 to 7 February 1989 and electrophoretically surveyed for genetic variation at 30 biochemical loci. Genetic data were used to detect mixtures of breeding populations in the wintering aggregation of mallards that migrate into the Southern High Plains and to estimate the proportion of total genetic variation partitioned among breeding populations represented on the study area there. Wintering mallards represented mixtures of genetically heterogeneous breeding populations with a minimum of 10.4-11.7% of the genetic variation partitioned among populations represented. Genetic information may be useful in detecting mixtures of breeding populations in specific wintering areas within and among flyways.

AB The recent development of the lattice gas automata method and its extension to the lattice Boltzmann method have provided new computational schemes for solving a variety of partial differential equations and modeling chemically reacting systems. The lattice gas method, regarded as the simplest microscopic and kinetic approach which generates meaningful macroscopic dynamics, is fully parallel and can, as a result, be easily programmed on parallel machines. In this paper, we introduce the basic principles of the lattice gas method and the lattice Boltzmann method, their numerical implementations and applications to chemically reacting systems. Comparisons of the lattice Boltzmann method with the lattice gas technique and other traditional numerical schemes, including the finite difference scheme and the pseudo-spectral method, for solving the Navier-Stokes hydrodynamic fluid flows will be discussed. Recent developments of the lattice gas and the lattice Boltzmann method and their applications to pattern formation in chemical reaction-diffusion systems, multiphase fluid flows and polymeric dynamics will be presented.

AB The isolation of habitat patches is often cited as having a major impact on the dynamics of small populations occupying patches in a complex landscape. Few studies, however, have provided field data demonstrating that isolation has an identifiable effect on specific populations independent of other factors such as local habitat quality or that landscape factors such as corridors can alleviate such effects. We conducted field surveys of Bachman's Sparrow (Aimophila aestivalis) populations in regions, which we call linear landscapes where suitable habitat patches were isolated to varying degrees from potential sources of dispersing birds. In these linear landscapes isolated patches of habitat were less likely to be colonized than were nonisolated patches. We also found that corridor configuration; of habitat patches improved the ability of sparrows to find and settle in newly created patches. These results suggest that for species that do not disperse easily through inhospitable landscapes, habitat occupancy at a regional scale can be enhanced by careful landscape design and planning.

AB Stress corrosion cracking (SCC) test specimens of Al-Li-Cu alloy that were subjected to fixed-displacement loading and exposed to aerated 3.5 wt% sodium chloride (NaCl) solution for I week failed < 24 h after removal into ambient atmospheres. Anodic dissolution-based mechanisms proposed previously for this phenomenon were amended based upon further characterization of the rapid cracking process. Amendments were based on studies of the relative electrochemical behavior of the microstructural elements in the subgrain boundary (SGB) region, time-to-failure SCC testing in a simulated crack solution, evolution of crack potential and pH with time, fractographic examination of failed samples, and x-ray diffraction (XRD) of films passivating crack walls. Results suggested an active path existed along SGB that was composed of the highly reactive T-1 (Al(2)CuL(i)) precipitate phase and a solute-depleted zone that did not passivate readily when exposed to the crack environment. The matrix phase along crack walls appeared to passivate in the crack environment, thereby confining attack to the SGB region. This active path was enabled when cracks were isolated from a bulk environment, but it was disabled otherwise. Potential and pH conditions required for cracking were reviewed, along with the formation of a hydrotalcite, Li-2[Al-2(OH)(6)](2) . CO3 . 3H(2)O, film that appeared to be responsible for passivating crack walls.

AB Electrochemical potential measurements of materials in radioactive waste environments will be important in determining if the materials have a propensity for stress corrosion cracking (SCC) and pitting. Potential measurements require a reference electrode (RE), but the effect of ionizing radiation on the potential generated by the RE has been uncertain. Two common types of RE were evaluated under Co-60 gamma radiation at room temperature. The silver-silver chloride (Ag-AgCl) and mercury-calomel (Hg-Hg2Cl2) RE showed essentially no radiation effects up to a dose rate of 2.1E6 rad/h and dose of 9.4E8 rad, indicating these RE would be useful for in-lank studies. The long-lived design of the Ag-AgCl RE showed serious potential deviations at doses of 2.E8 rad but would be the electrode of choice in many situations because it is simple to maintain. The mixed-potential theory was used to explain the radiation effects.

AB On the basis of recent laboratory and field experiments, recombinant baculoviruses expressing insect-specific neurotoxin genes show an increased speed of insect killing compared with natural baculoviruses. They can also induce symptoms similar to those induced by chemical insecticides and have the potential for widespread use in agriculture. Current studies of the ecology and molecular biology of baculoviruses should further improve efficacy and better define safety.

Likewise, occultation by our planet's core-mantle structure can help constrain the locations of extragalactic neutrino sources. Neutrino observations from the Earth's surface thus motivate new levels of collaboration between astrophysics and geophysics.

AB Long-term use of a constructed wetland to treat landfill leachate requires that the saturated hydraulic conductivity be maintained and clogging avoided to prevent overland now, which bypasses the treatment process. This paper describes the application of an equation developed for prediction of cumulative drainage volume from hillslopes to measure the saturated hydraulic conductivity (K-s) of substrates used in rock-reed filters. Outflow was measured at five intervals during the first 26 months of operation. The values of K-s obtained by the drainage equation compared favorably with values calculated from a more difficult method based on Darcy's law. Results indicate that the finest substrate (a sand-and-gravel mixture) became almost completely clogged, and that the presence of reeds (Phragmites australis) did not maintain or increase the conductivity. Hydraulic conductivity of pea-gravel (0.5-cm diameter) and coarse-gravel (3-cm diameter) substrates with reeds did decrease in the 26-month period.

AB Heavy shade presents serious challenges for primary producers and food-limited herbivores in forest streams. In this study, we examined the response of periphyton and grazing snails (Elimia clavaeformis) to summer shade in White Oak Creek (WOC), a second-order stream in a Tennessee deciduous forest. Three experiments were performed: (1) in situ manipulation of light and snail density to test the effects of light limitation and grazing; (2) construction of photosynthesis-irradiance (P-I) curves to test for shade adaptation by periphyton; and (3) measurements of snail growth vs. irradiance, to quantify the indirect relationship between grazers and an abiotic constraint on photosynthesis. In the first experiment, light and snail densities were manipulated in a 2 x 2 factorial design: two light treatments were created by removing streamside vegetation from four sites in WOC and by pairing each of these sites with an adjacent, shaded site; two snail density treatments at each site were created by adding snails at normal (970 individuals/m(2)) and low (50 individuals/m(2)) density to the two sides of Plexiglas channels. Snails at normal densities cropped periphyton biomass to low levels regardless of light regime, but periphyton productivity was higher at the open sites where snails grew faster and accumulated more lipid. Snail growth and lipid accumulation were strongly affected by intraspecific competition in both light regimes. In the second experiment, photosynthesis-irradiance curves for periphyton from shaded and open sites illustrated considerable shade adaptation: shaded periphyton was 2 times more efficient at low irradiance than was periphyton from open sites. Despite the greater efficiency of shaded periphyton at low irradiance, integrated primary production estimated with photosynthetic models was 4 times greater in the open because shade adaptation provided only partial compensation for the very low irradiances in the shade. In the third experiment, in situ snail growth again increased with decreasing shade. The growth vs. irradiance response resembled a P-I curve: snail growth increased almost linearly with increased light and then leveled off at a photon flux density of approximate to 7 mol m(-2). d(-1). If this curve primarily reflects rates of food supply, then periphyton production and grazer growth in WOC and similar streams is light-limited at a photon flux density <7 mol m(-2). d(-1). Bottom-up effects of light limitation were propagated very strongly in WOC, where the invertebrate fauna is dominated by a grazer that appears to escape top-down control.

AB Deep saline aquifers were investigated as potential disposal sites for CO2. The capacity of deep aquifers for CO2 disposal in the U.S. is highly uncertain. A rough estimate, derived from global estimates, is 5-500 Gt of CO2. Saline aquifers underlie the regions in the U.S. where most utility power plants are situated. Therefore, approximately 65 percent of CO2, from power plants could possibly be injected directly into deep saline aquifers below these plants, without the need for long pipelines.

AB Photoreduction of CO2 using p-terphenyl as a photosensitizer and a tertiary amine as a sacrificial electron donor is efficiently catalyzed by cobalt macrocycles in methanolic acetonitrile solutions. Studies of the mechanism of CO2 reduction in the catalytic system using Co(II)HMD(2+) (HMD = 5,7,7,12, 14,14-hexamethyl-1,4,8,11-tetraazacyclot-4,11-diene) have been carried out using continuous and flash photolysis techniques. The transient spectra reveal the formation of p-terphenyl radical anion, the Co(I)HMD(+) complex, the 5-coordinate [Co(I)HMD-CO2](+) complex, and the six coordinate [S-Co(III)HMD-(CO22-)](+) complex (S = solvent) in the catalytic system. The importance of changes in the Co-II/I reduction potential and the geometry around the Co center was studied by the use of several different complexes.

AB The accumulation of carbon dioxide in the atmosphere, primarily as a result of the combustion of fossil fuels, has been linked to potential global climate change. Capture and utilization of the carbon dioxide by microalgae has emerged as a promising technology to help reduce emissions from fossil fuel-fired power plants. Microalgae are of particular interest because of their rapid growth rates and tolerance to varying environmental conditions. We are currently conducting experiments on the growth of microalgae exposed to simulated flue gas. This technology is envisioned for open raceway cultivation ponds as a low cost implementation strategy. Coupling the production of fuel or commodity chemicals with the use of flue gas carbon dioxide as a microalgal nutrient is envisioned to be a cost-effective method of reducing the amount of carbon dioxide contributed to the atmosphere by fossil fuel-fired power plants.

AB The abundance of natural gas as a natural resource and its high hydrogen content make it a prime feedstock candidate for a low cost supply of hydrogen. The thermal decomposition of natural gas by methane decomposition produces carbon and hydrogen. Conventional steam reforming of natural gas produces CO2 and hydrogen and requires more process energy. Methane decomposition produces the least amount of greenhouse gas CO2 emissions per unit of hydrogen and can be totally eliminated when the carbon produced is sequestered or sold as a material.

AB A common thread joining many engineered materials used dominantly under compressive loading is the presence of a high modulus secondary phase, either fiber or particulate, embedded within a lower modulus matrix phase. To improve their toughness, a frictional or a less-than-coherent interface is strived for in the manufacture of these composite materials. To form a better understanding of the complex behavior of these materials, numerical and experimental models were developed by the U.S. Bureau of Mines that allowed a wide range of micromechanical and fracture behavior to be investigated under compressive loading. Finite element modeling illustrates the effects of interfacial friction and elastic moduli mismatch between the reinforcement and the matrix. Additional results show that packing density or non-dilute concentration of reinforcements have little effect upon the micromechanical behavior under uniaxial compressive loading. These numerical results were then substantiated:by crack initiation experiments on model composite materials.

The sensor measured absorption in the spectral region of 230.0-300.0 nm, allowing direct detection of benzene and its derivatives (including toluene, xylenes, and ethylbenzene). The spectra of these compounds contain considerable fine structure, and deconvolution of the mixture spectra allowed a quantitative determination of the concentration of benzene to be made. Relative levels of total aromatic hydrocarbons were also determined. The trends measured by the on-line sensor were in agreement with standard off-line laboratory analyses and were obtained continuously in realtime. Continuous monitoring allowed transient events as well as mid- to long-term trends in the extraction process to be measured.

AB Studies of phase distributions and emission factors for polycyclic aromatic hydrocarbons (PAH) in environmental tobacco smoke (ETS) require collection and analysis of very small samples. To achieve the necessary selectivity and sensitivity, a method has been devised and tested for extraction and cleanup of gas- and particulate-phase ETS samples. Gas-phase species were trapped by polymeric sorbents, and particles were trapped on filters. The samples were extracted with hot cyclohexane, concentrated, and passed through silica solid-phase extraction columns for cleanup. After solvent change, the PAH were determined by high-performance liquid chromatography with two programmed fluorescence detectors. PAH concentrations in 15-mg aliquots of National Institute of Standards and Technology Standard Reference Material (SRM) 1649 (urban dust/organics) agreed well with published values. Relative precision at the 95% confidence level was 8% for SRM 1649 and 20% for replicate samples (5 mg) of ETS particles. Emission factors have been measured for a range of gas- and particulate-phase polycyclic aromatic hydrocarbons in ETS. The emission factors per cigarette were 13.0 +/- 0.5 mg of particulate matter, 11.2 +/- 0.9 mu g for gas-phase naphthalene, and 74 +/- 10 ng for particulate benzo[a]pyrene.

AB Radiation synovectomy has been shown to be an effective treatment for the rheumatoid arthritic knee. In this study, we evaluated the suitability of rhenium-188 as a radiation synovectomy agent. In addition, we were successful in labelling sulphur colloid with Re-188. In vitro stability tests revealed that more than 95% of the Re-188 remained in colloid form over a 3-day period. Intra-articular injection of Re-188 sulphur colloid into arthritic rabbit joints was followed by gamma camera imaging to quantify the leakage. The mean retention percentages of Re-188 colloid in arthritic knees were 93.7% (+/-1.4%), 90.8% (+/-1.7%) and 87.2% (+/-0.6%) at 1 h, 1 day and 2 days, respectively. A biodistribution study of the arthritic rabbits revealed that the highest activity outside the knees was in the liver and the kidneys. Our preliminary results indicate that Re-188 sulphur colloid may be an effective radiopharmaceutical for radiation synovectomy.

It is found that the nu1 --> 2 transition is 110 cm-1 lower than the nu0 --> 1 fundamental. Theoretical calculations show good agreement with the experimental observations and predict the existence of a strongly bound two-phonon bound state. A vibrational lifetime of 19 ps and a similar ground-state recovery time are measured.

AB The vertical density profiles of medium density fiberboard, particleboard, and oriented strandboard were measured by a drill resistance technique and were compared with the vertical density profiles of the same specimens measured with a scanning gamma ray method. The drill resistance technique as applied to composite panel products uses a linear relationship between the panel density and the drill resistance values. The drill resistance technique was found to be a good measure of the vertical density profile of composite panel materials, especially for medium density fiberboard. The technique is inexpensive, safe, portable and has the potential to be adopted as an on-line density profile method.

ID LASER-INDUCED FLUORESCENCE; TISSUE; LUNG; DYSPLASIA; BREAST
AB Laser-induced fluorescence spectroscopy was used to measure fluorescence emission of normal and malignant tissue during endoscopy in patients with esophageal cancer and volunteers with normal esophagus. The spectroscopy system consisted of a nitrogen-pumped dye-laser tuned at 410 nm for excitation source, an optical multichannel analyzer for spectrum analysis, and a fiberoptic probe designed for both the delivery of excitation light and the collection of fluorescence emission from tissue. The fluorescence lineshape of each spectrum was determined and sampled at 15-nm intervals from 430 to 716 nm. A calibration set of spectra from normal and malignant spectra was selected. Using stepwise discriminate analysis, significant wavelengths that separated normal from malignant spectra were selected. The intensities at these wavelengths were used to formulate a classification model using linear discriminate analysis. The model was then used to classify additional tissue spectra from 26 malignant and 108 normal sites into either normal or malignant spectra. A sensitivity of 100% and specificity of 98% were obtained.

MODEL
AB A numerical model which describes oxygen isotope exchange during burial and recrystallization of deep-sea carbonate is used to obtain information on how sea surface temperatures have varied in the past by correcting measured delta(18)O values of bulk carbonate for diagenetic overprinting. Comparison of bulk carbonate and planktonic foraminiferal delta(18)O records from ODP site 677A indicates that the oxygen isotopic composition of bulk carbonate does reflect changes in sea surface temperature and delta(18)O. At ODP Site 690, we calculate that diagenetic effects are small, and that both bulk carbonate and planktonic foraminiferal delta(18)O records accurately reflect Paleogene warming of high latitude surface oceans, biased from diagenesis by no more than 1 degrees C. The same is likely to be true for other high latitude sites where sedimentation rates are low. At DSDP sites 516 and 525, the effects of diagenesis are more significant. Measured delta(18)O values of Eocene bulk carbonates are more than 2 parts per thousand lower at deeply buried site 516 than at site 525, consistent with the model prediction that the effects of diagenesis should be proportional to sedimentation rate. Model-corrections reconcile the differences in the data between the two sites; the resulting paleotemperature reconstruction indicates a 4 degrees C cooling of mid-latitude surface oceans since the Eocene. At low latitudes, the contrast in temperature between the ocean surface and bottom makes the carbonate delta(18)O values particularly sensitive to diagenetic effects; most of the observed variations in measured delta(18)O values are accounted for by diagenetic effects rather than by sea surface temperature variations. We show that the data are consistent with constant equatorial sea surface temperatures through most of the Cenozoic, with the possible exception of the early Eocene, when slightly higher temperatures are indicated. We suggest that the lower equatorial sea surface temperatures for the Eocene and Oligocene reported in other oxygen isotope studies are artifacts of diagenetic recrystallization, and that it is impossible to reconstruct accurately equatorial sea surface temperatures without explicitly accounting for diagenetic overprinting.

AB An experimental approach was developed to measure the mutual solubilities of organic fluids and water over a wide range in temperature and pressure. By using a gold bag, rocking autoclave, and a precision high pressure liquid chromatography pump, samples of both equilibrated fluids may be obtained. Using this technique the solubility of liquid p-xylene in water was measured as a function of temperature and pressure from 298 to 423 K (at constant pressure) and from 0.1 to 50 MPa (at constant temperature). The results were used to calculate the partial molal thermodynamic quantities: Delta (G) over bar(soln), Delta (H) over bar(soln), Delta (S) over bar(soln), Delta (C) over bar(psoln), and Delta (V) over bar(soln). Calculated values for these quantities at 298 K are: Delta (G) over bar(soln) = 15.92 (+/-.13) kJ/mol,Delta (H) over bar(soln) = 1.643 (+/-.214) kJ/mol, Delta (S) over bar(soln) = -47.90 (+/-.72) J/mol-K, Delta (C) over bar(psoln) = 214.7 (+/-3.8) J/mol-K, and Delta (V) over bar(soln) = 31.08 (+/-3.80) cm(3)/mol.

AB Mineral-bound humic substances modify inorganic surfaces in subsurface sediments, changing the nature and number of complexation sites for contaminants. Because of adsorptive enrichment, the reactive surface area or site concentration contributed by mineral-bound humic substances can exceed that of dissolved or colloidal humic substances by two orders of magnitude. Mineral-bound humic materials may, therefore, provide a major sink for the removal of contaminants in groundwater. The reactivity of the humic substance is primarily determined by the structural and bulk chemical properties of the humic substance and the aqueous solution chemistry.
Organic and inorganic contaminants sorb readily to mineral-bound humic substances. The sorption of hydrophobic organic compounds increases as ionic strength decreases, is enhanced by divalent cations, and displays non-linear isotherms and competitive adsorption behavior. Collectively, these results suggest that hydrophobic adsorption, rather than phase partitioning, is the primary sorption mechanism for neutral organic molecules on these particle coatings. Mineral-bound humic substances augment, rather than change, the intrinsic complexation properties of mineral surfaces for metal cations. The degree of sorption enhancement promoted by mineral-bound organic material varies strongly with pH and depends on the magnitude of the stability constants between the metal cation and the humic substance, the strength and magnitude of adsorption of the humic substance by the mineral surface, and the extent of aqueous complex formation between the non-sorbed humic substance and metal. The simplest sorption model for humate-modified surfaces is the linear additivity model (LAM). Sorption data for certain hydrophobic organic compounds and metal cations appear to conform to this model.

AB Decontamination efforts during weapons production has historically involved the generation of mixed waste that was composed of organically chelated radionuclides. Waste disposal has traditionally involved shallow land burial, and not until recently has the subsurface migration of the organically complexed contaminants (co-contaminants) become a significant concern. The objective of this study was to provide an improved understanding of the geochemical processes that control the fate and transport of ethylenediaminetetraacetate (EDTA) chelated contaminants in heterogeneous subsurface environments. A batch technique was utilized to investigate the kinetics and mechanisms of Co(II)EDTA2- and Sr(II)EDTA2- interaction with naturally heterogeneous saprolites and laboratory prepared pyrolusite (beta-MnO2) coated SiO2. The interaction of Co(II)EDTA2- with the subsurface media was characterized by a Mn-oxide induced oxidation of the co-contaminant to form Co(III)EDTA-. The Co(III)EDTA- complex exhibited time-dependent adsorption on the subsurface material, and this adsorption process was unaffected by differences in ionic strength. The oxidation reaction of Co(II)EDTA2- to Co(III)EDTA- by subsurface Mn-oxides was catalytic such that significantly more Co(II)EDTA2- was oxidized relative to the net Mn(IV) reduced. The interaction of SrEDTA2- with the subsurface media was characterized by a solid phase induced dissociation of the co-contaminant. Subsurface Fe and Al sources effectively dissociated the SrEDTA2- complex, and Fe(III)EDTA- and Al(III)EDTA- were formed. Competition of Al and Fe for complex formation with EDTA was time-dependent and controlled by the availability of the Al and Fe sources and the stability of the metal-EDTA complexes. The contaminant Sr remained unchelated and existed as a reactive, divalent cation. The implications of the EDTA chelate on the fate and transport of contaminants in subsurface environments are discussed.

AB Predicting fluid flow and transport behavior in unsaturated, fractured rock is greatly simplified where matrix imbibition can be modeled as a linear function of the square root of time (t(1/2)); however, such treatment implicitly assumes homogenous matrix properties. To investigate matrix heterogeneity effects, we perform a simple experiment in which xray imaging is used to measure the imbibition of water from a flowing fracture into a slab of volcanic tuff. Experimental results show matrix imbibition to follow a linear t(1/2) relationship even though the saturated hydraulic conductivity of the tuff varies by over four orders of magnitude.

TI QUANTITATIVE VISUALIZATION OF ENTRAPPED PHASE DISSOLUTION WITHIN A

SO GEOPHYSICAL RESEARCH LETTERS
LA English
DT Article
AB An experiment was conducted to demonstrate the utility of quantitative fracture flow visualization techniques in the study of entrapped fluid phase (air) dissolution into a flowing phase (water) within a horizontal, transparent, analog rough-walled fracture. The fracture aperture field and phase occupancy were measured using light transmission techniques and then combined to calculate bulk water-phase saturation within the fracture as a function of time. Fracture relative permeability as a function of water-phase saturation showed a smooth power law behavior during dissolution. Periodic step pulses of clear water within the dyed water inflow yielded dye concentration fields that demonstrate channeling induced by the entrapped air phase. Clusters of the entrapped air-phase exhibited three types of dissolution behavior: general shrinkage, interfacial recession along cluster appendages, and cluster splitting. Locations for the advance of the wetting phase (water) into a nonwetting entrapped air cluster on its dissolution are not always correlated with either zones of high mass transfer rate (as inferred from gradients in the pulsed dye concentration fields) or with narrow apertures where the wetting phase has been thought to most easily invade. These results suggest that within an individual cluster of the entrapped phase, fluid pressure is at equilibrium and that the path of cluster shrinkage may be controlled primarily by capillary forces resulting from the full three-dimensional curvature that minimizes surface energy of the phase interface.
