We find that the interference between E1 and E2 amplitudes produces large asymmetries in the angular and momentum distributions of the emitted protons and Be-7 fragments. By measuring these asymmetries one may be able to put constraints on the E2 component and thereby improve the accuracy of the E1 strength that can be extracted from Coulomb dissociation experiments. We also investigate the effect of higher-order dynamical processes and find that they reduce the asymmetries in reactions on high-Z targets. They also reduce the effect of E2 transitions on the dissociation probability and on the peak height of the decay energy spectrum compared to predictions of first-order perturbation theory.

It focuses on (Ij the nuclear community, specifically the technical experts who perform accident analyses, and the regulators who use these analyses in making risk assessments or policy decisions; and (2) the general public. This article summarizes these groups' approaches to nuclear risk and explores the effects of cognition and cultural conditioning in creating these differences.

In response to these concerns, out-of-pile experimental projects were initiated by the U.S. Nuclear Regulatory Commission and the French Nuclear Protection and Safety Institute, at Oak Ridge National Laboratory (ORNL) and the Commissariat a l'Energie Atomique (CEA), respectively. Both experimental efforts were designed for source term characterization of the fission products (FPs) released from LWR fuel samples under test conditions representative of severe accidents, i.e., in oxidizing or reducing atmospheres at temperatures up to 2700K (at ORNL) and 2570K (at CEA). The experimental devices, procedures, and parameters are described. The combined database of available results is summarized and related to experimental conditions. Using Booth diffusion theory, diffusion coefficients of the FPs were calculated, and their evolution with temperatures in the 1070 to Z700 K range were plotted. The results show the good agreement between the independently determined ORNL and CEA FP diffusion coefficient values. By plotting the data in Arrhenius fashion, if has been possible to do the following: 1. quantify the thermal activation coefficients for both volatile and low volatile FPs 2. identify classes of FPs whose release behavior does not follow a purely diffusional mechanism, but rather depends on chemical interactions with the environment; i.e., they exhibit mixed diffusional and transport-dependent mechanisms. A model supported by these experimental results and based on the CORSOR-Booth code is proposed and compared with CORSOR calculations. To facilitate the comparison, a model based on FP diffusion mechanisms that was developed at ORNL and adapted with CEA experimental data is proposed. This CEA model, as well as CORSOR-Booth calculations are compared with the ORNL experimental data in a blind test. Additional experimental work is in progress to determine the releases of nonvolatile FPs and transuranics at temperatures up to fuel melting as well as FP deposition mechanisms under both oxidizing and reducing conditions. An effort is made to quantify the dependence of the temperature transient delta T/delta t as well as the oxygen potential effects on the release kinetics. Those data will allow further verification and extension of the field of application for our model. C1 OAK RIDGE NATL LAB,DIV CHEM TECHNOL,OAK RIDGE,TN 37831.

More than 100 simulations have been performed using the RELAPS/MOD2.5 computer program. The RELAP5 input model used for the simulations is quite detailed, including 17 parallel channels in the core region, the three active heat exchanger cells, the pressurizing system, and the secondary cooling system. Special models are developed to represent the effects of shrinkage in the primary coolant pressure boundary and cavitation of the primary coolant pumps. Six locations in the primary coolant system are selected as pipe break sites to determine the worst-case scenario. At each of the locations, simulations are completed for a range of break diameters. The reactor is assumed to survive the transient as long as the hot-spot heat flux remains below the flow excursion limit. In addition to the baseline simulations, extensive parametric simulations are conducted to ensure that the modeling assumptions used are conservative. For a break diameter of 5.1 cm at any of the six locations in the system, the hot-spot heat flux remains beneath this limit, and furthermore, no boiling occurs in the fuel region. A summary fable for all results is presented, and results are discussed in detail for the worst-case 5.1-cm break scenario. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

U.S.-designed PWRs similar to the V213 are used for reference and comparison. This V213 risk assessment is based on comparison analyses of the following aspects: accident progression event free success paths for typical PWR accident initiating events, safety aspects in reactor design, and perceived performance of reactor safety systems. The four initiating events considered here were taken from a U.S. Nuclear Regulatory Commission summary report on severe accident risk: loss of offsite power with station blackout, large-break loss-of-coolant accident (LOCA), medium-break LOCA, and small-break LOCA. The success probabilities for the V213 reaching a non-core-damage state after the onset of the selected initiating events are calculated for two scenarios: (a) using actual component reliability data from U.S. PWRs and (b) assuming common component reliability data. U.S. PWR component reliability data are used because of the unavailability of such data for the V213 at the rime ofthe analyses. While the use of U.S. PWR data in this risk assessment ofthe V213 does strongly infer V213 comparability to U.S. plants, the risk assessment using common component reliability does not have such a stringent limitation and is thus a separate scoping assessment of the V213 engineered safety systems. The results of the analyses suggest that the V213 has certain design feature's that significantly improve the reactor's safety margin for the selected initiating events and that the V213 design has a relative risk of core damage for selected initiating events that is at least comparable to U.S. PWRs. It is important to realize that these analyses are of a scoping nature and may be significantly influenced by important risk factors such as V213 operator training, quality control, and maintenance procedures. Additionally, the analyses make no implications as to the effects of the selected initiating events on the health and safety of the public.

Our theory requires no assumption on the substructures that constitute the whole domain, so the substructures can be of arbitrary shape and of different size, The global coarse mesh is allowed to be non-nested to the fine grid on which the discrete problem is to be solved, and neither the coarse mesh nor the fine mesh need be quasi-uniform, In addition, the domains defined by the fine and coarse grid need not be identical, The one important constraint is that the closure of the coarse grid must cover any portion of the fine grid boundary for which Neumann boundary conditions are given. In this general setting, our algorithms have the same optimal convergence rate as the usual two level overlapping domain decomposition methods on structured meshes, The condition number of the preconditioned system depends only on the (possibly small) overlap of the substructures and the size of the coarse grid, but is independent of the sizes of the subdomains.

The analysis leads to a simple analytic expression for the slope error, which enables the distortion performance to be estimated in practical situations. It also provides an understanding of the effect of the various parameters on the goodness of the cooling process and an insight into the underlying physics. The analysis is applied to determining the design steps needed to achieve low slope errors and/or high-heat-removal rates with this type of mirror. The slope-error performance of various materials in a specific design are compared and the best performance is obtained from (in order) invar, silicon, and silicon carbide.

Simulations performed with different forms of P(theta) with the same value of(cos theta) result in the collection of significantly different fractions of the incident photons, particularly when small-numerical-aperture delivery and collection fibers are employed.

On the basis of a theoretical analysis, it is predicted that the stress marking this transition varies not only with the grain size and the stress exponent n for power-law creep, as concluded before, but also with the Peierls stress tau(p) of the material if n > 3 such that, the higher tau(p), the higher is sigma(t), under otherwise identical conditions. It is demonstrated that there is a reasonable agreement between this theoretical prediction and experimental observations for a wide range of materials.

In this approach, classical statistical mechanics are combined with the local-harmonic method in order to obtain thermodynamic and mechanical properties of solids, including the free energy. Specifically, we present results for a general Mie (Lennard-Jones m, n) potential. The dependence of these properties on potential parameters is examined and a number of results are summarized, We find that the analytical theory yields remarkably accurate results for such thermodynamic quantities as volume, energy, free energy and bulk modulus to temperatures approaching the melting point.

It is shown that the appearance of double-well-related features is extremely sensitive to the time scale and that fluctuating polarization domains separated by domain walls have different freezing temperatures than their walls. The domain walls have kink or pulse exiton-type character and may decay into a dynamic or static charge transfer process for decreasing velocities.

Onset of amorphization was detected after the lowest ion doses, reflecting amorphization by individual ions. The ion dose required for complete amorphization increased nearly linearly with ion energy over the range 0.5-3.5 MeV for all ions. Amorphization cross-sections have been determined for all the ions and energies used. The amount of damage, expressed as the number of displacements per atom, required for complete amorphization decreased with increasing ion energy or ion mass. The decrease with increasing ion energy or ion mass is due to a decrease in irradiation-enhanced annealing of amorphous volumes as a result of a decrease in the fraction of low-energy atomic displacements to Ge. Increasing the fraction of low-energy atomic displacements to Ge atoms during Kr irradiation by simultaneous 1 MeV electron irradiation increased the Kr ion dose required for complete amorphization. Radiation annealing is believed to be due to freely migrating defects produced by low-energy atomic displacements to Ge atoms.

The model equation (G. Kaniadakis, P, Quarati, Phys. Rev, E 49 (1994) 5103) includes a nonlinear term due to the Pauli exclusion principle which has been disregarded up to now. A new numerical method to study the time evolution of the distribution function is presented, The method can be applied to any potential and allows us to describe accurately and efficiently a Fermi gas. In this work we focus on the differences between the results of the linear case, in which the effects of the exclusion principle are not considered, and the nonlinear case, in which these effects are taken into account.

Diffuse scattering experiments within the region of total external reflection were carried out to investigate the mesoscopic roughness of the interfaces. The data are explained quantitatively using the distorted wave Born approximation (DWBA) for correlated layer systems with self-affine interfaces. Because all samples were grown under identical conditions the interface parameters of the simpler systems were used for the more complex samples in order to reduce the number of free parameters in the refinement. The resulting trends for the roughness amplitude and the in-plane correlation lengths are compared to predictions from different growth models.

Consequently, the bulk (110) planes contain equal amounts of Fe and Al distributed as interlocking rectangles. Unlike the NiAl(110) surface, which retains the (1 x 1) in-plane symmetry of the bulk, FeAl(110) reconstructs to form an ordered, incommensurate overlayer. The reconstructed layer is discerned from x-ray diffraction rods at half-order positions along the [1(1) over bar0$] direction, and displaced +/-0.2905 from integer positions along the [001] direction. Peak widths reveal excellent long-range order. Specular reflectivity measurements above and below the Fe K alpha edge can be reproduced using a model containing a single reconstructed overlayer with an Fe:Al ratio of 1:2, consistent with FeAl2.

The CaF2 overlayer exhibits an incommensurately modulated structure parallel to the heterointerface, consisting of a triangular network of discommensurations, which separate domains with two different Ca site occupations H3 and T4. The 2D spatial modulation of the overlayer is induced by the competition between the strong covalent-like Ca-Si bonding at the interface and the ionic Ca-F bonding in the film. Remarkably, the in-plane periodic lattice distortion generated at the interface propagates many atomic layers through the CaF2 film. Specular reflectivity and standing wave measurements suggest that the CaF2-Si interface is unstable towards the formation of an intermediate CaSi2 layer. In situ temperature-dependent strain measurements revealed that the strong interfacial Ca-Si bending prevents a complete in-plane lattice relaxation up to 700 degrees C while the overlayer expands considerably normal to the interface.

With bromide in solution, we observe an in-plane diffraction pattern that is consistent with a hexagonal, close-packed, bromide monolayer. The monolayer is incommensurate, but aligned with the underlying platinum lattice, and is present over a wide potential range. The in-plane diffraction measurements are correlated with X-ray specular reflectivity results, to confirm the surface coverages and give information about the surface normal structure. The initial adsorption of copper in the presence of bromide or chloride anions also results in an ordered structure with an incommensurate hexagonal unit cell. Changes in the in-plane scattering intensities at X-ray energies close to the Cu K-edge indicate that the adsorbed layer must include both copper and the halide. The data are described by a bilayer structure very similar to the (1 1 1) planes of CuCl (or CuBr).

The morphology and growth dynamics of the localized corrosion sites or pits were studied as the applied potential was varied from the cathodic region where the Cu surface is relatively free of oxide films to the anodic region where surface roughening occurs by general corrosion with concomitant formation of an oxide film. Quantitative analysis of the experimental results indicates that early pitting proceeds in favor of nucleation of pit clusters over individual pit growth. It was found that the lateral distribution of the pits is not random but exhibits a short-range order as evidenced by the appearance of a side peak in the transverse off-specular reflectivity. The position, height, and width of the peak was modeled to yield the average size, nearest-neighbor distance (within any one of the clusters), and over-all density of the pits averaged over the entire illuminated surface. In addition, measurements of the longitudinal off-specular reflectivity indicate a bimodal depth distribution for the pits, suggesting a ''film breaking'' type of pitting mechanism.

A crystalline monolayer is formed at the surface a few degrees above the bulk freezing temperature. The structure of the monolayer has been determined on an angstrom scale. Two widely different patterns of behavior emerge, which depend on the length difference of the two components, Delta n. For small Delta n the surface properties and structure vary continuously with concentration. For large Delta n, however, the variation is discontinuous, exhibiting surface segregation. Furthermore, a new surface crystalline structure appears for a well-defined range of compositions and temperatures, and surface freezing is completely suppressed for another range. A Flory-Huggins theory based on competition between entropic mixing and a repulsive interaction due to chain length mismatch accounts well for the observed phenomena.

The Neel transition is suppressed for Cr layer thickness < 42 Angstrom. For > 42 Angstrom of Cr, the Neel temperature T-N initially increases rapidly and then asymptotically approaches its bulk value with a three-dimensional transition-temperature shirt exponent value of lambda = 1.4 +/- 0.3. Neutron diffraction confirms both the Cr antiferromagnetic order and the existence of the incommensurate, transverse spin density wave whose nesting wave vector is the same as that of bulk Cr. The ordering of the Cr dramatically alters the coupling of the Fe layers. The biquadratic Fe interlayer coupling observed for T > T-N vanishes below T-N as confirmed by polarized neutron reflectivity. The behavior can be understood in terms of finite-size and spin frustration effects at rough Fe-er interfaces. C1 OAK RIDGE NATL LAB,DIV SOLID STATE,OAK RIDGE,TN.

The bottom layer of Ni had the same thickness for all samples (140 Angstrom) while the top layer of Fe varied from sample to sample (16-90 Angstrom). The magnetic moment of iron was found to be dependent on the layer's thickness. For Fe layers of 32 Angstrom or less, the Fe magnetization was an order of magnitude smaller than that of bulk BCC Fe, indicating that Fe is either in a non-magnetic state or that its ordering is antiferromagnetic. For Fe layers of 60 Angstrom or more, the Fe moment was found to be in the plane of the film, constant throughout its entire layer, and with a value (2.0 mu(B)/atom) approaching that of bulk iron.

The scattering profile is well described by a broad Lorentzian plus a narrow Lorentzian-squared lineshape with widths that, for temperatures sufficiently close to T-N, differ by a factor of ten or more.

We observe scattering associated with the (010) magnetic truncation rod. The scattering exhibits the expected resonance as a function of incident photon energy, and is observed to vanish at T-N On heating. The L-dependence of the observed scattering exhibits the characteristic Vineyard profile as the angle of incidence is swept through the critical angle. Based on the refractive index, we estimate the penetration depth of the grazing-incidence measurements reported here to be approximately 50 Angstrom. C1 BROOKHAVEN NATL LAB,DEPT PHYS,UPTON,NY 11973.

Resonant reflectivity measurements were carried out by tuning the X-ray energy around the respective K-edge of Fe and Cr. We were able to obtain excellent fits to the data and get consistent geometry and composition parameters from the reflectivity measurements at six different X-ray energies. We obtained valuable information on the interface composition of the superlattice and observed also a slight variation in composition at the bottom and top interfaces. The information obtained using this method allows a determination of not only the electron density but also the composition profiles of the multilayers. This non-destructive technique is a promising tool for the determination of the chemical composition of thin film. C1 ARGONNE NATL LAB,DIV MAT SCI,ARGONNE,IL 60439. CUNY BROOKLYN COLL,NEW YORK,NY.

Using the (004) Bragg reflection, we find that the center of the Bi ad-dimers lies 1.72 Angstrom above the bulk-like Si(004) surface atomic plane. Using the (008) Bragg reflection, we find that the room temperature root-mean-square vibrational amplitude of the Bi adatoms normal to the surface plane is 0.13 Angstrom. This direct determination of the adsorbate vibrational dynamics verifies earlier assumptions regarding the magnitude of adsorbate surface vibrations on Si surfaces, and suggests that the vibrational amplitude of dimerized group V/Si(001)-(1 x 2) structures is independent of the mass of the adsorbate.

Reflectivities of 75-95% in the theta(c)-2 theta(c) range are currently obtained from the Ni/C-Ti system. The Ti-Be multilayer system is presented here as a possible alternative to the Ni/C-Ti system. Titanium is one of the few elements which has a negative neutron scattering length, while beryllium has a relatively large positive scattering length. This makes for bilayer structures which have excellent neutron contrast, a necessary requirement of supermirror devices. Single-bilayer-spacing Ti-Be multilayers were prepared by magnetron sputtering onto 2 mm thick silicon (001) substrates. Depositions were made with 10-80 bilayers at two different bilayer thicknesses of approximately 90 and 110 Angstrom. Bulk layers of Ti and Be were also prepared to determine the scattering length density of each deposition component. The samples were measured at the Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory on the POSYII reflectometer. First order Bragg peak reflectivities of up to 64% were observed. Data from the two bulk depositions and one multilayer deposition have been fitted using a genetic algorithm developed at IPNS. For the bulk depositions, the scattering length densities of Ti and Be depositions are - 2.2 x 10(-6) and 10.3 x 10(-6) Angstrom(-2), respectively. In addition, results clearly indicate the presence of a 50 Angstrom thick oxide layer on the bulk Ti deposition. The neutron scattering length density profile obtained from the neutron reflectivity measurements are in good agreement with XPS analysis of the oxide him which showed a mixture of TiO2 and Ti2O3.

Three independent reflectivities are obtained by taking measurements with the sample magnetized in a magnetic field perpendicular to the surface and subsequently parallel to it, and using in the latter geometry neutrons polarized either in the direction of the field or opposite to it. The procedure consists of tyro steps. First, from the three reflectivities both the real and imaginary parts of the reflection coefficient of the unknown film are extracted within the framework of the rigorous dynamical theory. Second, the neutron scattering-length density (and consequently the chemical depth profile) is obtained by a suitable numerical technique for the conventional Schrodinger inverse scattering problem. Computer experiments were conducted for selected cases: starting from the profiles the reflectivities were calculated in a limited range of q and then the original profiles were successfully recovered. The influence on the accuracy of the recovered depth profile of the counting statistics and the cutoffs at low and high q are discussed.

We report here on X-ray reflectivity studies from the surfaces of liquid mercury to q(z) greater than or similar to 2.8 Angstrom(-1), and gallium to q(z) greater than or similar to 3.0 Angstrom(-1), that show peaks which clearly demonstrate atomic layering with spacing on the order of the atomic diameter. The exponential decay of layer penetration into the bulk for Ga (6.5 Angstrom) is larger than for Hg (3-3.5 Angstrom). The prominent features of the layering remain unchanged under self-assembled monolayers of thiols. The Ga layering shows an unexpected strong temperature dependence. Differences between the reflectivity from Ga and Hg at small q(z) indicate fundamental differences in the surface structure for these two liquid metals.

We present new data using a non-equilibrium Raman technique studying the temperature dependence of photoinduced carrier relaxation which points to the existence of polaronic states in the metallic phase, i.e. in the normal state of superconducting YBa2Cu3O6.9 and La1.85Sr0.15CuO4. From the symmetry of the phonons coupled to them, we deduce a predominantly A(g) symmetry for the Cu-O-2 plane electronic states in the CT gap. As a result, it is argued that both itinerant and localized (and polaronic) states are present at the same time in the normal phase of high-T-c cuprate superconductors and it is suggested that a number of apparently conflicting experimental results can be understood using this hypothesis.

We summarize the experimental evidence for the significant role of non-equilibrium phonons in their observed behavior. However, the difficulties of forming a high transparency interface and the lack of inelastic channels appear to limit their effectiveness as non-equilibrium phonon sensors.

The superconducting tape is usually produced by co-deforming a ductile silver sheath containing a superconducting oxide. Since the conventional thermomechanical process has failed to yield sufficient J(c) values for most liquid-nitrogen temperature applications, new approaches are needed to improve the critical current density, J(c). This study investigated the feasibility of improving J(c) by increasing the shear and compressive stresses in the silver-sheathed Bi2Sr2Ca2Cu3O10+x (BSCCO-2223) tapes during the rolling. To investigate the effects on the J(c) of the stress state during rolling, specific stress states were imposed by rolling the BSCCO tapes embedded at different locations within thick steel blocks. mire compression loading was achieved in the center plane of the blocks, while a combined compression-shear loading state was produced away from the center plane. Higher compressive hydrostatic stress at the tape edge was obtained by confining the tape width. Tapes deformed with a shear stress component exhibited higher J(c) values than tapes subjected to pure compression. In addition, the compressive hydrostatic stress reduced the porosity in the oxide near the tape edge and, as a consequence, increased the J(c) value.

Some results on the decay processes of these hollow atoms, mainly formed below the surface, for argon, iron, and krypton ions are presented. By measuring the changes of the number of electrons in the L and M shells of the ions, compared to the lifetime of the K shell, it has been possible to evaluate the mean time for the filling of the L and M shells. These measurements are compared with a model of interaction of the ions with the surface. C1 LAWRENCE LIVERMORE NATL LAB,LIVERMORE,CA 94550.

A storage ring equipped with an electron cooler was used for the measurements. Methods employed to reduce the electron energy distribution and improve the accuracy of resonance energy measurements have yielded an energy resolution of 30 meV full width at half maximum at low energies, and an energy uncertainty better than 30 meV. The high energy resolution results from the use of an adiabatic expansion technique to reduce the transverse electron energy distribution. The improved accuracy in energy determinations is achieved through the inclusion of variations in the ion velocity, which occur during scans of the electron velocity, in the relative velocity transformations. Calculations of the resonance strengths and energies were made using two different methods, multiconfiguration Dirac-Fock and multiconfiguration Breit-Pauli approximations. A comparison of the experimental data to the calculations shows fair agreement in both the spectral features and integrated intensities above 3 eV. However, poor agreement is found below 3 eV.

Analysis of the experimental data on the basis of the adiabatic theory of direct ionization has been made and parameters of the quasimolecule, namely, the energy of the initial 2p sigma state coupled with the continuum, the effective charge, and the real and imaginary parts of the internuclear distance at which the ''superpromoted'' diabatic term crosses boundary of continuum, have been determined. The values of the initial-state energy and the effective charge agree well with the corresponding parameters of the Li united atom, whereas the dynamical characteristics ReR(E) and ImR(E) reveal considerable influence of electron correlations. The possibility for the development of an alternative method of quantitative spectroscopy of quasimolecules based on the analysis of experimental data on differential cross sections for direct ionization is discussed.

Rev. A 51, 2122 (1995)] for single-quantum annihilation of positrons with bound electrons. Fully relativistic calculations of total cross sections for the production and the annihilation of positrons involving an electron bound in the K or L shells of atoms have been performed in screened atomic potentials, for a number of elements ranging from germanium (Z=32) to thorium (Z=90) and for positron kinetic energies up to 4 MeV above threshold. Very good agreement with earlier calculations, that had been performed over a more restricted range of elements and energies, is obtained, also confirming that the Z and shell dependence previously seen continues at higher energies. The results presented here extend theory to energies where recent experiments have been performed, at forward angle, which were assumed to characterize the Z and shell dependence of the corresponding total cross sections. Our new theoretical predictions are not consistent with the strong dependence of the K- and L-shell bound-pair-annihilation cross sections on the nuclear charge of the target reported in those experiments. An explanation of these discrepancies is proposed, namely, that it is not correct to assume the same ratios for total cross sections as for forward distributions. This is demonstrated using existing data for the related photoeffect process, and it is seen that such forward data are indeed consistent with the pair-annihilation experiments.

The chainlike structure proposed for the polymerized material is confirmed. Lattice constants extracted from the HRTEM images are consistent with those determined earlier by x-ray diffraction. The fine structure in the EELS spectrum of KC60 shows the sp(2) nature of the carbon bonds along with features which distinguish the bonding in this alkali fulleride from that of other fullerenes. Both the HRTEM and EELS studies show that polymerized KC60 is exceedingly resilient against damage induced by a 200-keV electron beam, in sharp contrast to the behavior of pristine C-60.

In the doping range studied (0.05 less than or equal to x less than or equal to 0.25) the electronic properties of the material exhibit a crossover from semiconducting to metallic behavior. The magnetoresistance is highest in the semiconducting state. A correlation was found between the energy gap determined from the de conductivity and the energy scale identified from neutron scattering data. The results are interpreted in terms of a double-exchange model. C1 BROOKHAVEN NATL LAB,DEPT APPL SCI,UPTON,NY 11973.

Superconductivity appears at pressures above about 9 kbar, near the critical pressure required to suppress antiferromagnetic order [T-N(P=0)=36 K]. Onset of superconductivity occurs at a temperature of approximate to 350 mK. Resistivity measurements as a function of held at constant temperature allow us to build an H*-T phase diagram for the onset of superconductivity. A Ginzburg-Landau analysis of the initial slope of the critical field leads to an effective mass of m*/m(0) approximate to 200, supporting the heavy-fermion nature of superconductivity in CeRh,Si,. Magnetic ac susceptibility (chi(ac)) shows a diamagnetic response corresponding to about 1% of perfect diamagnetism. The size of the feature in chi(ac) also is strongly peaked at a pressure of approximate to 9 kbar. C1 FLORIDA STATE UNIV,DEPT PHYS,TALLAHASSEE,FL 32306.

In particular, we study the dependence of the localization length on the frequency, the dielectric function ratio between the scatterer and the background, and the filling ratio of the scatterer. We find that the gaps of the a-polarized waves can sustain a higher amount of disorder than those of the p-polarized waves, due to the fact that the gaps of the a-polarized waves are wider than those of the p-polarized waves. For high frequencies, the gaps of both types of waves easily disappear, the localization length is constant and it can take very small values. The optimum conditions for obtaining localization of EM waves in 2D systems will be discussed. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT PHYS & ASTRON,AMES,IA 50011.

The consequences of an initial excitation corresponding to low-energy dynamics are investigated. A number of features are found including the sensitive role of the polarization angle of incident light in determining the regimes of validity. Our earlier finding that the semi-classical approximation improves in validity in a well defined ''massive oscillator'' limit involving small phonon frequency is borne out. In the opposite Limit of large phonon frequency, the semiclassical approximation and the discrete nonlinear Schrodinger equation are found to coincide with each other but to differ significantly from the exact evolution.

In low field (H less than or equal to 100 G) TbNi2B2C orders antiferromagnetically at Neel temperature T-N=(14.9 +/- 0.1) K. Weak ferromagnetic (WF) behavior is found for T less than or equal to 8 K and H less than or equal to 10 kc. Both phase transitions are also detected in zero-field in-plane resistivity rho(ab)(T) measurements. In contrast, previous low-field M(T,H) data showed antiferromagnetic ground states for (Gd,Dy,Ho,Er,Tm)Ni2B2C crystals. The origin of the WF ordering, given the point symmetry (4/mmm) of the Tb+3 ions, is addressed together with the observed in-plane anisotropy in the high-field magnetization. Possible reasons for the absence of superconductivity above 2 K in TbNi2B2C are also discussed. Finally, a partial H-T magnetic phase diagram of TbNi2B2C is presented for H parallel to[110] and aspects of the similar H-T diagram for H parallel to[100] are discussed.

The magnitude of the wave vector is close to that obtained in the Ho, Er, and Gd compounds. This observation provides additional evidence that there are common Fermi-surface nesting features along a* in the rare-earth nickel boride carbides which cause the magnetic ordering of the rare-earth moments via the Ruderman-Kittel-Kasuya-Yosida mechanism. Below approximately 8 K, the experimental results indicate the development of a small ferromagnetic component. C1 IOWA STATE UNIV SCI & TECHNOL,DEPT PHYS & ASTRON,AMES,IA 50011.

The impurity scattering is modeled by short-range potential scattering with arbitrary phase shift, while scattering due to spin fluctuations is calculated within a weak-coupling Hubbard model picture, The conductivity is characterized by a low-temperature residual Drude feature whose height and weight are controlled by impurity scattering, as well as a broad peak centered at 4 Delta(0) arising from clean-limit inelastic processes. Results are in qualitative agreement with experiment despite missing spectral weight at high energies. C1 UNIV TENNESSEE,DEPT PHYS & ASTRON,KNOXVILLE,TN 37996.

With. one exception, Ni on Cu(001), the calculated spin moments are considerably enhanced at the surface, which is in agreement with previous theoretical and experimental work for some of the presently studied systems. We argue that the Ni-d-Cu-d hybridization is responsible for the reduced Ni spin moment in the case of a Ni monolayer on a Cu(001) substrate. The orbital moment is enhanced at the surface for ail of the studied cases, sometimes by as much as a factor of 2 relative to the value found in the bulk. Based on our theoretical calculations we propose that an experimental confirmation of an enhanced orbital magnetic moment on a surface is most likely to be found for a monolayer of Co on a Cu(001) substrate or for the Fe(001) surface layer. Experimental work on Co on Cu(001) confirm this behavior. C1 LOS ALAMOS NATL LAB,DIV THEORET,LOS ALAMOS,NM 87545.

A. Abrikosov, Phys. Rev. B 52, R15 738 (1995)] under conditions when the odd (d symmetry) order parameter is favorable for a clean substance. The critical temperature decreases rapidly with increasing impurity concentration according to the general pair-braking formula and tends to zero at a critical concentration. Since, however, the critical temperature for the phase with an even order parameter is only weakly influenced by impurities, it eventually exceeds the T-c of the odd phase, and this means a phase transition to the even phase. The T-c curve is expected to have a kink and a long tail. RP Abrikosov, AA (reprint author), ARGONNE NATL LAB,DIV MAT SCI,9700 S CASS AVE,ARGONNE,IL 60439, USA.

The valence-band spectra are quite different for films with and without antiferromagnetic interlayer exchange coupling, demonstrating that these multilayers have different silicide phases in their spacer layers. Comparison with previously published fluorescence data on bulk iron silicides shows that the Fe concentration in the silicide spacer layers is substantial. Near-edge x-ray-absorption data on antiferromagnetically coupled multilayers in combination with the fluorescence data demonstrate unambiguously that the silicide spacer layer in these films is metallic. These results on the electronic structure of buried layers in a multilayer film exemplify the wide range of experiments made possible by high-brightness synchrotron sources.

A yield point for plastic deformation of the flux-line lattice is linked to the onset of a dissipation anomaly previously associated with a flux-line lattice melting transition. The resonance (10 kHz range) of radiation-damaged samples bifurcates into patterned sidebands at high drives, with additional nonlinear response emerging above 200 kHz, which may signal the onset of chaos.

The cross sections for elastic/quasielastic scattering, deeply inelastic, and fissionlike processes were measured at beam energies of E(lab) = 166, 177, 222, 260 MeV for S-32+W-182, E(lab) = 220, 240, 270, 298 MeV for Ti-48+ Er-166, and E(lab) = 339, 390, 421 MeV for Ni-60 + Sm-154, respectively. The maximum contribution of complete-fusion fission processes to the fissionlike cross section is estimated on the basis of expected angle-mass correlations for such reactions. The results show a strong entrance-channel dependence as predicted by the extra-push model. RP Back, BB (reprint author), ARGONNE NATL LAB,DIV PHYS,ARGONNE,IL 60439, USA.

These ''stretched'' states, at excitation energies of 17.79 MeV, 19.80 MeV (both mainly T = 0), and 18.98 MeV (mainly T = 1), have well known nuclear structure and are used as a nuclear filter to examine the tensor and spin-orbit components of the effective nucleon-nucleus interaction at 350 MeV. A complete set of spin observables was obtained at an angle of 22 degrees in the laboratory frame, whereas the D-ss' and D-sl' observables were measured at laboratory angles of 17, 22, 27, and 32 degrees. The data are compared with distorted-wave impulse approximation calculations from several theoretical models. C1 OHIO UNIV,ATHENS,OH 45701. TRIUMF,VANCOUVER,BC V6T 2A3,CANADA.

First, we show that the present approach can reproduce the measured (p,xp') and (p,xn) angular distributions leading to continuous final states without adjusting any parameters. Second, we show results of a detailed study of the preequilibrium reaction processes, the stepwise contributions to the angular distribution, comparisons with the quantum-mechanical Feshbach-Kerman-Koonin theory, and the effects of momentum distribution and surface refraction/reflection to the quasifree scattering. Finally, the present method was used to assess the importance of multiple preequilibrium particle emission as a function of projectile energy up to 1 GeV.

In the relaxation time approximation we determine the criteria under which a time-dependent relaxation time leads to thermalization of the partons. We calculate the entropy production due to collisions for the general time-dependent relaxation time. In a perturbative QCD approach on the other hand, we can, given the initial conditions, estimate the effective relaxation time due to elastic collisions; this will be an upper limit only since radiative processes will also contribute to thermalization. We find that the parton gas does thermalize eventually but only after having undergone a phase of free streaming and gradual equilibration where considerable entropy is produced (''after burning''). The final entropy and thus particle density depends on the collision time as well as the initial conditions (a ''memory effect''). Results for entropy production are presented based upon various model estimates of early parton production. C1 UNIV CALIF BERKELEY,LAWRENCE BERKELEY LAB,DIV NUCL SCI,BERKELEY,CA 94720.

The strong absorption limit of the Serber model reproduces both data sets quite accurately. The transparent limit, on the other hand, can reproduce the width of the Be-11 data reasonably well but it fails dramatically for the B-8 data. The reason is that the absorption of the projectilelike fragment has a much larger effect on the width when the orbital angular momentum of the valence nucleon is nonzero.

mass of the B-s(0) meson SO PHYSICAL REVIEW D LA English DT Article ID COLLISIONS AB We measure the mass of the B-s(0) meson by reconstructing the decay chain B-s(0)-->J/psi phi, J/psi-->mu(+)mu(-), and phi-->K+K-. The data are obtained from 19.3 pb(-1) of integrated luminosity of <(p) over bar p> collisions at root s=1.8 TeV using the Collider Detector at Fermilab. A sample of 80 000 inclusive J/psi-->mu(+)mu(-) events is used to study systematic biases in track reconstruction and to calibrate the momentum scale. We reconstruct the kinematically similar decays B+-->J/mu K+ and B-0-->J/psi K*(0) to study the mass measurement technique used for the B-s(0) meson. Based on the observation of 32 +/- 6 candidates, the mass of the B-s(0) meson is measured to be 5369.9 +/- 2.3 +/- 1.3 MeV/c(2) and the mass difference between B-s(0) and the average mass of B+ and B-0 is determined to be 89.7 +/- 2.7 +/- 1.2 MeV/c(2).

These data were obtained with a free polarized neutron beam, a polarized proton target, and a large magnetic spectrometer for the outgoing proton. The neutron beam kinetic energies were 484, 567, 634, 720, and 788 MeV Combining these results with earlier measurements allows the determination of the pure spin observables C-SS, C-LS, and C-LL at 384, 634, and 788 MeV for c.m. angles 25 degrees less than or equal to theta(c.m.)less than or equal to 180 degrees and at 720 MeV for 35 degrees less than or equal to theta(c.m.)less than or equal to 80 degrees. These data make a significant contribution to the knowledge of the isospin-0 nucleon-nucleon scattering amplitudes. C1 ARGONNE NATL LAB, ARGONNE, IL 60439 USA.

They are fitted to data on inclusive K-0 production in e(+)e(-) annihilation taken by Mark II at SLAG PEP (root s=29 GeV) and by ALEPH at CERN LEP. Our fragmentation functions lead to a good description of other e(+)e(-) data on inclusive K-0 production at various energies. They also nicely agree with the K-S(0), transverse-momentum spectra measured by H1 at the DESY ep collider HERA, by UA5 at the CERN collider, and by CDF at the Fermilab Tevatron.

The 1 sigma lower limit on the lifetime against such decays is 3.5 x 10(26) yr. This result can be used to establish a 1 sigma upper limit on the ratio of the charge-nonconserving to the normal weak interaction decay width of the neutron, Gamma(n-->p + v(e) + <(v)over bar (e)>)/Gamma(n-->p + e(-) + <(v)over bar (e)>)less than or equal to 8 X 10(-27).

The signature was exclusive Lambda(0) Lambda(0) production from diffractive dissociation of H's striking a plastic scintillator. We observed 40 Lambda(0) Lambda(0) events with a background of 3.2 events, but see no evidence of H dissociation. Using our additional observation of 187+/-39 Lambda(0)K(S)(0) events produced by coherent diffractive dissociation of neutrons from carbon for normalization, we place an upper limit of 1 mb/sr on the production of H's with lifetimes greater than or similar to 10(-8) s.

The mean-squared displacement is found to grow as a linear function of time during chaotic motion, indicating deterministic diffusion. The diffusion coefficient can be significantly influenced by the proximity of a window containing a periodic solution. We find that diffusion associated with intermittent chaos can be described in terms of an interleaving of the diffusion properties of the separate modes taking part in the intermittency.

Here it arises from a doubling of the number of effectively classical degrees of freedom, which ark nonlinearly coupled in a Gaussian variational approximation (TDHF) to full quantum mechanics. The resulting first-order nondissipative autonomous flow system shows energy dependent transitions between regular behavior and semiquantum chaos, which we monitor by Poincare sections and a suitable frequency correlation function related to the density matrix. We discuss the general importance of this form of deterministic chaos and point out the necessity to study open (dissipative) quantum systems, in order to observe it experimentally.

Here D is the differential operator d/dy, rho(y) is the density profile of the fluid, W(y) is the perturbed fluid velocity, k is the wave number of the perturbation, and Gamma(2)=gamma(2)/g, where gamma is the growth rate of the instability and g is the strength of the gravitational field. The connection between the Rayleigh and the Schrodinger equations is made by defining a potential V(y) associated with rho(y), a wave function Psi(y) associated with W(y), and an energy E associated with k. We consider several examples of the Rayleigh equation and show that they correspond to well-known problems in quantum mechanics such as a particle in a box, the harmonic oscillator, the Coulomb potential, etc. We illustrate the inversion symmetry of the Rayleigh equation under rho(y)-->1/rho(-y), and in an appendix we give and illustrate the more general potential V(g), which includes surface tension and shear flow, the latter associated with the Kelvin-Helmholtz instability.

This method significantly simplifies the derivation of the IST perturbation results. We also present a specific example for which the adiabatic IST perturbation results and the collective coordinate method results exactly coincide. This is achieved by establishing a correct Lagrangian formalism for soliton parameters via transforming dynamical variables that obey a deformed Poisson structure to ones that possess a canonical Poisson structure.

A pure shake-off behavior is observed, with a smooth and monotonic intensity rise from zero to saturation, confirming theoretical predictions. Different onset energies are observed for the spectral features, but the shape of the spectrum is found to be invariant for energies higher than 50 eV above threshold. Full-spectrum fits based on ab initio Dirac-Fock calculations and measured onset energies conclusively show the satellites to result from 2p spectator transitions only, as predicted.

The largest J is obtained for a planar distribution P-pl(Theta), with a splay angle Theta(opt) = +/-5 degrees. A comparison of P-pl(Theta) and a Gaussian distribution P-G(Theta) suggests that pinning by the latter is controlled by large-angle tails of the Gaussian which appear to enhance thermal creep rate. Numerical simulations confirm the existence of the regimes where vortex motion is promoted rather than suppressed by splay. C1 OHIO STATE UNIV,COLUMBUS,OH 43210. ARGONNE NATL LAB,ARGONNE,IL 60439.

Yamada et al., Bull. Am. Phys. Sec. 40, 1877 (1995)] in order to understand the basic physics of the experiment, including the effect of the external driving force, and the difference between co-and counterhelicity cases of the experiment. The problem is reduced to a one-dimensional (1-D) resistive magnetohydrodynamic (MHD) model. A special class of holonomic boundary conditions is defined, under which a unique sequence of global equilibria can be obtained, independent of the rate of reconnection. This enables one to break the whole problem into two parts: a global problem for the ideal region, and a local problem for the resistive reconnection layer. The calculations are then carried out and the global solution for the ideal region is obtained in one particular case of holonomic constraints, the so called ''constant force'' regime, for both the co- and counterhelicity cases. After the sequence of equilibria in the ideal region is found, the problem of the rate of reconnection in the resistive reconnection region is considered. This rate tells how fast the plasma proceeds through the sequence of global equilibria but does not affect the sequence itself. Based on a modified Sweet-Parker model for the reconnection layer, the reconnection rate is calculated, and the difference between the co- and counterhelicity cases, as well as the role of the external forces is demonstrated. The results from the present analysis are qualitatively consistent with the experimental data, predicting faster reconnection rate for the counterhelicity merging and yielding a positive correlation with external forcing.

The rate nu at which the temperatures parallel and perpendicular to the applied magnetic field relax to a common value has been measured over the temperature range 28 to 3.8 x 10(5) K and the magnetic field range 20 to 60 kG. This rate nu is closely related to the plasma collision frequency. When the cyclotron radius r(c) is large compared to the classical distance of closest approach b (r(c)/b much greater than 1), the measured values of nu are in agreement with conventional collision theory. When the cyclotron radius is small compared to the classical distance of closest approach (r(c)/b much less than 1), nu drops precipitously as r(c)/b is decreased, in agreement with the many-electron adiabatic invariant theory of O'Neil and Hjorth.

Controlled Nucl. Fusion Res. 1, 51 (1987)]. First, helium was puffed into the beam-heated phase of a supershot discharge, which induced a degradation from supershot to L-mode confinement in about 100 ms, far less than the current relaxation time. The q and shear profiles measured by a motional Stark effect polarimeter showed little change during the confinement degradation. Second, rapid current ramps in supershot plasmas altered the q profile, but were observed not to change significantly the energy confinement. Thus, enhanced confinement in supershot plasmas is not due to a particular q profile, which has enhanced stability or transport properties. The discharges making a continuous transition between supershot and L-mode confinement were also used to test the critical-electron-temperature-gradient transport model. It was found that this model could not reproduce the large changes in electron and ion temperature caused by the change in confinement. (C) 1996 American Institute of Physics.

A set of coupled differential equations is derived which describes the spatial-temporal growth of forward and near forward Raman scattering for plane wave pumps. An exact solution for direct forward scattering is obtained for physically relevant initial/boundary conditions. Furthermore, the asymptotic behavior at near forward angles is compared to finite width analyses in which the paraxial ray approximation is made. Noise sources for Raman forward scattering are examined. The consequences of these results to present and near term experiments are discussed. (C) 1996 American Institute of Physics.

This acronym was chosen in analogy with FACE (Free Air CO2 Enrichment), a technique which produces elevated CO2 concentrations [CO2] in open field conditions. The FATI system simulates global warming in small ecosystems of limited height, using infrared heaters from which all radiation below 800 nm is removed by selective cut-off filters to avoid undesirable photomorphogenetic effects. An electronic control circuit tracks the ambient canopy temperature in an unheated reference plot with thermocouples, and modulates the radiant energy from the lamps to produce a 2 5 degrees C increment in the canopy temperature of an associated heated plot (continuously day and night). This pre-set target differential is relatively constant over time due to the fast response of the lamps and the use of a proportional action controller (the standard deviation of this increment was <1 degrees C in a 3 week field study with 1007 measurements). Furthermore, the increase in leaf temperature does not depend on the vertical position within the canopy or on the height of the stand. Possible applications and alternative designs are discussed.

Biological induction of SAR usually follows plant cell death resulting from the plant hypersensitive response (HR) elicited by an avirulent pathogen or from disease necrosis caused by a virulent pathogen. The elicitation of the HR and disease necroses by pathogenic bacteria is controlled by hrp genes. Previously, it was shown that the Pseudomonas syringae 61 (Pss61) HrpZ(Pss) protein (formally harpin(Pss)) elicited the HR in plants. In this study, it is shown that HrpZ(Pss) induced SAR in cucumber to diverse pathogens, including the anthracnose fungus (Colletotrichum lagenarium), tobacco necrosis virus and the bacterial angular leaf spot bacterium (P. s. pv. lachrymans). A hrpH mutant of Pss61, which is defective in the secretion of HrpZ(Pss) and, possibly, other protein elicitors, failed to elicit SAR. Pathogenesis-related (PR) proteins, including peroxidase, beta-glucanase and chitinases, were induced in cucumber plants inoculated with Pss61, C. lagenarium or HrpZ(Pss). The induction patterns of PR proteins by HrpZ(Pss) and Pss61 were the same, but were different from that induced by C. lagenarium. Interestingly, the hrpH mutant induced two of the three identified PR proteins, despite its failure to induce SAR. These results suggest that proteinaceous elicitors, such as HrpZ(Pss) that traverse the bacterial Hrp secretion pathway are involved in the biological induction of SAR and that at least some PR proteins can be induced by bacterial factors that are not controlled by hrp genes.

Extensins also occur in muro as a small pool of soluble monomeric precursors to network extensin. These precursors were prepared in milligram quantities by salt elution from the surface of intact cells grown as tomato suspension cultures. Based on an FPLC (Superose-6) gel filtration assay of cross-linked extensin oligomers, a pl 4.6 extensin crosslinking peroxidase isozyme was partially purified from the culture growth medium. Purification involved: volume reduction, ultracentrifugation to remove pectin and co-adsorbed cationic peroxidase, followed by chromatography of anionic extensin peroxidase (pl 4.6) on DEAE-Trisacryl and TSK-gel DEAE-5PW columns. With tomato P1 extensin as substrate and 60 mu M H2O2 as co-substrate, at 23 degrees pl 4.6 extensin peroxidase gave a K-m of 0.22 mM P1 and a V-max of 70 mu mol P1 cross-linked min(-1) mg(-1) enzyme, at the optimum pH 5.5. Assayed with 12 different extensins from representative monocots, dicots, and gymnosperms, the pl 4.6 isozyme cross-linked highly selectively, indicating two natural groups: cross-linking or CL-extensins and non-cross-linking or NCL-extensins. CL-extensins contained the X-Hyp-Val-Tyr-Lys motif and were also highly glycosylated. However, the simplest motif common to CL-extensins but absent from NCL-extensins was Val-Tyr-Lys. Thus, peroxidative coupling of extensin monomers and resistance of the resultant oligomers to depolymerization by anhydrous HF suggests that the intermolecular cross-link involves tyrosine or lysine.

A remained unchanged under the current CO2 concentration but decreased during the day under the doubled CO2 concentration, resulting in a 46% enhancement in the early morning, 26% at midday, and 15% in the late afternoon by the elevated CO2. The decrease during the day under the doubled CO2 concentration may represent end-product inhibition, because the sucrose and the starch contents increased during the day proportionally more than under the current CO2 concentration. The (CO2)-C-14 activity in sink leaves was maximal 3 h after labeling under the doubled and at 5 h under the current CO2 concentration, indicating faster movement of photosynthate out of source leaves and into sink tissues under the doubled CO2 concentration, which may have been responsible for the sustained enhancement in A under the doubled CO2 concentration.

N-methyl-N,N'-diphenylurea) were determined ill combustible cartridge case (CCC) wall specimens from 120 mm M829 rounds which had been exposed to elevated temperatures in environmental chamber,,; or which were returned from deployment in Southwest Asia. The results suggest that the migration of these components from the propellant is uniform about the circumference of the adhesive joint between the CCC body and adapter but not longitudinally above and below the joint. The accumulation appears to be linear with time of exposure, with both nitroesters migrating at approximately the same rate with similar energies of activation. The conventional sampling and analysis method is compared with it new micro-sampling and analytical method which reduces solvent waste and extraction time, and considerably reduces damage to the rounds from removal of the analytical specimen.

Insertion of the cDNA behind a cytomegalovirus promoter and selection by aminoglycoside resistance in transfected HEK cells yielded clones secreting large quantities of mAChE into the medium. The enzyme sediments as a soluble monomer at 4.8 S. High levels of expression coupled with a one-step purification by affinity chromatography have allowed us to undertake a crystallographic study of the fasciculin-mAChE complex. Complexes of two distinct fasciculins, Fas1-mAChE and Fas2-mAChE, were formed prior to the crystallization and were characterized thoroughly. Single hexagonal crystals, up to 0.6 mm x 0.5 mm x 0.5 mm, grew spontaneously from ammonium sulfate solutions buffered in the pH 7.0 range. They were found by electrophoretic migration to consist entirely of the complex and diffracted to 2.8 Angstrom resolution. Analysis of initial X-ray data collected on Fas2-mAChE crystals identified the space group as P6(1)22 or P6(5)22 with unit cell dimensions a = b = 75.5 Angstrom, c = 556 Angstrom, giving a V-m value of 3.1 Angstrom(3)/Da (or 60% of solvent), consistent with a single molecule of Fas2-AChE complex (72 kDa) per asymmetric unit. The complex Fas1-mAChE crystallizes in the same space group with identical cell dimensions. C1 UNIV CALIF SAN DIEGO, DEPT PHARMACOL, LA JOLLA, CA 92093 USA.

The developmentally expressed 84-kDa myosin heavy chain kinase (MHCK) from Dictyostelium (Ravid S, Spudich JA, 1992, Proc Natl Acad Sci USA 89(13):5877-5881) is known to be a member of the protein kinase C (PKC) family. We have observed a rather striking homology between the large central domain of MHCK and the catalytic domain of diacylglycerol kinase (DGK), indicating that MHCK is in fact a gene fusion between a DGK and a PKC, possessing two separate kinase domains. The combined diacylglycerol kinase/myosin heavy-chain kinase (DGK/MHCK) may therefore have dual Functionality, possessing the ability to phosphorylate both protein and lipid. We present a hypothesis that DGK/MHCK can antagonize both actin and myosin assembly, as well as other cellular processes, by coordinated down regulation of signaling via myosin heavy-chain kinase activity and diacylglycerol kinase activity.

In contrast, up to 10-fold increases in frequencies of preneoplastic transformants, above control levels, were observed after exposure of rat tracheal epithelial cells to similar a-particle fluences on Pu-238 and Am-241 sources, Two alternative hypotheses are evaluated as an explanation for this apparent difference in the biological effect of ex particles emitted from different sources: (a) possible interactions between effects produced by ex particles and by low-energy photons, which occur with Pu-238, and Am-241 but not with Po-210; and (b) the influence of spatial relationships between exposed cells and the surface of the planar source, The data suggest that cell-to-source spatial relationships affect both survival and transformation markedly.

A total of 39-63% of gamma-ray-induced and 31-57% of alpha-particle-induced mutants had partial or total deletions of the HPRT gene. The proportion of these deletion events was dependent on radiation dose, and at the resolution limits employed there were no significant differences between the spectra induced by equitoxic doses of ex particles (0.2-0.4 Gy) and gamma rays (3 Gy). The molecular nature of the deletions was analyzed by the use of sequence tagged site (STS) primers and PCR amplification as a ''probe'' for specific regions of the human X chromosome within the Xq26 region. These STSs were closely linked and spanned regions approximately 1.7 Mbp from the telomeric side and 1.7 Mbp from the centromeric side of the HPRT gene. These markers include: DXS53, 299R, DXS79, yH3L, 3/19, PR1, PR25, H2, yH3R, 1/44, 1/67, 1/1, DXS86, D8C6, DXS10 and DXS144. STS analyses indicated that the maximum size of total deletions in radiation-induced HPRT mutants can be greater than 2.7 Mbp and deletion size appears to be dependent on radiation dose. There were no apparent differences in the sizes of the deletions induced by alpha particles or gamma rays. On the other hand, deletions containing portions of the HPRT gene were observed to be 800 kbp or less, and the pattern of the partial deletion induced by alpha particles appeared to be different from that induced by gamma rays.

In order to aid in the calibration of the instrument and to help minimize fabrication costs, we have applied simulation models to the ion beam spectrometer for the NASA/ESA Cassini mission to Saturn. In our previous article we studied the effects of misalignment and simple irregularities of the hemispherical surfaces on the performance of an electrostatic analyzer. We have considered a hemispherical electrostatic analyzer equipped with an aperture plate to collimate the stray electric field at the entrance apertures. The influence of a curved entrance aperture has also been added to the simulation model, and its effects have been studied in detail. A cylindrical three-dimensional simultaneous overrelaxation algorithm has been introduced to solve for the stray electric field. The maximum loss of transmitted particles with respect to the transmission of an ideal instrument has been set at 10%. We demonstrate that the deviation in the distributions of the energies is less than 0.2% and that the deviation in the distributions of entrance angles of transmitted particles is less than 0.1 degrees. It has been found that the energy resolution of an electrostatic analyzer can be improved from Delta E/E=(1.6+/-0.2)% to Delta E/E=(1.3+/-0.2)% by the introduction of front aperture plates. Through the introduction of curved entrance slits, the azimuthal angle resolution has changed from beta=(1.4+/-0.1)degrees for the simplified geometry simulation results of our previous article to beta=(2.3+/-0.1)degrees. We have confirmed that an accuracy of 25 mu m in the alignment of the two hemispherical surfaces is sufficient to give the instrument the desired resolutions. (C) 1996 American Institute of Physics.

In our experiments, optical fibers guided light of the GaAs samples from a laser diode source and from the samples to an optical detector, as might be the case in a practical application of such a device. Compressive and tensile strains were developed in the samples by flexing a cantilevered beam to which they were bonded. An important understanding of this strain distribution was obtained with the help of a finite-element calculation. The effects of sample width and the input optical energy distribution on the strain-induced change in optical transmission were measured. In the case of the distribution with the shortest median wavelength, over 80% change in transmission was observed for a compressive strain of only 0.05%. In addition, we calculated the strain sensitivity of this device, assuming only a rigid, strain-induced shift in its absorption edge. A comparison between experiment and calculation suggests that strain also caused the band edge of these samples to steepen in compression and broaden in tension. Another calculation suggests that this phenomenon is not intrinsic to the material. (C) 1996 American Institute of Physics.

The time required to produce a charge state has been measured by observing the arrival time of the ions at a Faraday cup after the source analyzing magnet. The results of these measurements have been compared to a simple sequential ionization model and are found to be in good agreement with the data. The data can be used to characterize the plasma electron density, electron temperature, and neutral atom density, since these are the only three adjustable parameters in the model and are sufficient to achieve good agreement for the time evolution of all observed charge states.

This fragmentation process leads to dilution of the intensity of the species of interest for radioactive ion beam (RIB) applications where beam intensity is at a premium. We have conceived an ion source that combines the excellent molecular dissociation properties of a thermal dissociator and the high ionization efficiency characteristics of an electron impact ionization source that will, in principle, overcome this handicap. The source concept will be evaluated as a potential candidate for use for RIB generation at the Holifield Radioactive Ion Beam Facility, now under construction at the Oak Ridge National Laboratory. The design features and principles of operation of the source are described in this article. (C) 1996 American Institute of Physics.

The source utilizes a highly permeable, high-work-function Ir ionizer (phi = 5.29 eV) for ionizing highly electropositive atoms/molecules; while for negative-surface ionization, the work function is lowered to phi = 1.43 eV by continually feeding cesium vapor through the ionizer matrix. The use of this technique for negative ion beam generation has the potential of overcoming the chronic poisoning effects experienced with LaB6 while enhancing considerably the efficiency for negative surface ionization of atoms and molecules with intermediate electron affinities. The flexibility of operation in either mode makes it especially attractive for radioactive ion beam applications and, therefore, the source will be used as a complementary replacement for the high-temperature electron impact ionization sources presently in use at the Holifield radioactive beam facility. The design features and operational principles of the source will be described in this report. (C) 1996 American Institute of Physics.

The source can produce similar to 1 mA of low energy (3 kV) singly charged ion current in the 10(-4) Torr pressure range. The source can also be operated in a more efficient low-pressure mode at an order of magnitude lower pressure. In this latter range, for example, the ionization efficiency of Ar is estimated to be 1% with charge states up to Ar8+ present. Operation in the low-pressure mode requires low power input (similar to 20 W). These features make the source especially suited for use with small accelerator systems for a number of applications including ion implantation, mass spectrometry, and atomic collision experiments where multiply charged ions are desirable. Design details and performance characteristics of the source are presented. (C) 1996 American Institute of Physics. C1 GEORGIA INST TECHNOL,SCH CHEM,ATLANTA,GA 30332.

We employ a magnetically confined microwave driven source, though the technique is not source specific and can probably be applied equally effectively to other plasma sources such as Penning and multicusp types. Specifically, we dope the plasma with about 1% H2O, which increases the proton fraction of a 45 keV 45 mA beam from 75% to 90% with 375 W 2.45 GHz power to the source and from 84% to 92% for 500 W when the source is operated under nonresonant conditions. Much of the remaining fraction of the beam comprises a heavy mass ion we believe to be N+ impurity ions resulting from the conditions under which the experiments were performed. If so, this impurity can easily be removed and much higher proton fractions could be expected. Preliminary measurements show the additive has no adverse effect on the emittance of the extracted beam, and source stability is greatly improved.

Ion sources consist of the plasma generator and the extraction system. Both parts can, due to high ion temperature or various aberrations, contribute to a degrading of the beam quality. Though the beam quality is determined by many more factors, the transverse motion of the particles certainly is one of the important parameters. Knowledge of it can be obtained by an emittance measurement. This is best done in a four-dimensional phase space, yielding a density distribution as function of the transverse spatial and momentum coordinates. Often, however, due to practical considerations, only two dimensions of the four-dimensional ''trace space'' are being measured. This two-dimensional data can be obtained as a section or as a projection of the four-dimensional trace space, where both methods have their merits. Projectional emittance measurements can usually be performed much easier and quicker, but by the projection of the four-dimensional space onto a two-dimensional plane information is lost. And although not all the particles of the beam are represented in a section of trace space, here aberrative distortions of the emittance can be seen most clearly and allow an easier comparison to numerically obtained data. The advantages and disadvantages of both methods are discussed. Numerical and experimental examples are presented. (C) 1996 American Institute of Physics.

For this application, any time delays that are excessively long with respect to the half-life of the radioactive species of interest can result in significant losses of the RIB intensity; therefore the times for effusive flow through the ion source are of fundamental importance since they set limits on the minimum half-life of radioactive species that can be processed in the source. Complementary experimental and computational techniques have been developed which can be used to determine the characteristic delay times for gaseous species in low-pressure ion source assemblies. These techniques are used to characterize the effusive delay times for the stable counterparts of various atomic and molecular radioactive species in the ORNL-rf source: He, Ne, Ar, Kr, Xe, H-2, CO, CO2, N-2, N2O, and O-2.

Rigorous survey research has shown that the public holds intense, negative images of ''nuclear'' and ''radioactive'' technologies, activities, and facilities. Potential host states and opponents claim that these negative images, coupled with an amplification of negative risk events, will potentially stigmatize the area surrounding such facilities and result in significant economic losses. At issue is whether a supporting social amplification of risk model is applicable to communities hosting facilities that are part of the U.S. Department of Energy Nuclear Weapons Complex. An initial assessment of high-profile discrete and cumulative key negative risk events at such nuclear facilities does not validate that there has been stigmatization or substantial social and economic consequences in the host areas. Before any changes to major national policy are implemented, additional research is required to determine if the nearby public's ''pragmatic logic,'' based on practical knowledge and experience, attenuates the link between public opinion and demographic and economic behaviors.

One technique used in ERAs involves estimating contaminant exposure to individual animals of selected species, which is then compared to a reference dose derived from the literature. Exposure estimates are conducted on those species which are representative of the different trophic levels found at the site. In many terrestrial systems, fossorial (burrowing) vertebrates are found in both lower and upper trophic levels. As part of the ERA conducted for Site 300, Lawrence Livermore National Laboratory's high-explosive test facility, contaminant exposures were estimated for fossorial and nonfossorial vertebrates spanning two trophic levels. The results of the evaluation revealed that a significant pathway by which fossorial vertebrates could be exposed to trichloroethylene in soil was through the inhalation of contaminated subsurface burrow air. This was the first time that the importance of this ecological exposure pathway has been recognized. The results of this analysis suggest that further research into the ecological significance of subsurface burrow air contaminated with volatile organic compounds is warranted.

These results provide limits within which a decision-maker can judge the importance of individual transport and fate processes, and the likely outcome of alternative cleanup strategies. The transport of hazardous materials may occur predominately through one particular pathway but, more often, actual or potential transport must be evaluated across several pathways and media. Multimedia models are designed to simulate the transport of contaminants from a source to a receptor through more than one environmental pathway. Three such multimedia models are reviewed here: MEPAS, MMSOILS, and PRESTO-EPA-CPG. The reviews are based on documentation provided with the software, on published reviews, on personal interviews with the model developers, and on model summaries extracted from computer databases and expert systems. The three models are reviewed within the context of specific media components: air, surface water, ground water, and food chain. Additional sections evaluate the way that these three models calculate human exposure and dose and how they report uncertainty. Special emphasis is placed on how each model handles radionuclide transport within specific media. For the purpose of simulating the transport, fate and effects of radioactive contaminants through more than one pathway, both MEPAS and PRESTO-EPA-CPG are adequate for screening studies; MMSOILS only handles nonradioactive substances and must be modified before it can be used in these same applications. Of the three models, MEPAS is the most versatile, especially if the user needs to model the transport, fate, and effects of hazardous and radioactive contaminants. C1 US EPA,WASHINGTON,DC 20460.

Substitution mutations were made in conserved regions of the DST element containing the sequences ATAGAT and GTA, which are invariant among several SAUR genes. The mutant DST elements were inserted into the 3' UTR of a beta-globin reporter gene and then assessed for their ability to destabilize the reporter transcript in stably transformed BY-2 tobacco cells. Their effect on reporter mRNA accumulation in both intact transgenic tobacco plants and stably transformed BY-2 cells was also measured. Five- and six-base substitutions in the ATAGAT and GTA regions of DSI, respectively, resulted in inactivation of the element as an instability determinant in ail systems tested. Smaller, two-base substitution mutations within the ATAGAT and GTA regions had varying effects on DST function in BY-2 cells, ranging from little or no effect to significant increases in reporter mRNA half-life and accumulation. In contrast, all two-base substitution mutations tested resulted In inactivation of DST in intact tobacco leaves. Together, these results indicate that bases within both the ATAGAT and GTA regions of DST are required for its function as an mRNA instability determinant in both BY-2 cells and leaves of transgenic plants, and that the sequence requirements for DST to function in leaves are more stringent.

Methods The behavioral and cognitive functions of 248 automotive workers were measured by a neurobehavioral test performance. Overtime, defined as number of hours worked greater than 8 h a day or greater than 5 d a week, was calculated from company payroll records for the week before the test day. The number of consecutive days worked before the test day was also determined. Results Cross-sectional data analysis by multiple linear regression, after adjustment for the effects of age, education, gender, alcohol intake, repeated grade in school, acute petroleum naphtha exposure, shift worked, job type, number of consecutive days worked before the test day, and number of hours worked an the test day before the testing, demonstrated that increased overtime was significantly associated with impaired performance on several tests of attention and executive function. Increased feelings of depression, fatigue, and confusion were also associated with increased overtime work. In addition significant interaction effects were observed for job type but not for naphtha exposure. Conclusions The findings support the hypothesis that overtime work results in impaired cognitive performance in the areas of attention and executive function and that both overtime hours and the number of consecutive days worked prior to a test day affect mood.

Bright luminescent fibrous cement has elevated Mn (>1000 p.p.m.), negative delta(13)C and intermediate delta(18)O values relative to other types of fibrous calcite. This cement reflects fibrous calcite that interacted with reducing Mn-rich fluids. Dully luminescent fibrous cement has elevated Fe (>400 p.p.m., positive delta(13)C and negative delta(18)O values relative to other fibrous cements. This cement was stabilized by burial fluids. Nonluminescent fibrous cement has low Mn and Fe (generally below 400.p.p.m.) and positive delta(13)C and delta(18)O values relative to other types of fibrous calcite. The latter cement is interpreted to be the best material for determining the isotopic composition of calcite precipitated in equilibrium with early to middle Caradoc seawater, which is delta(13)C=1 parts per thousand PDB and delta(18)O=-4 to -5 parts per thousand PDB. Results from this study and Ashgillian brachiopods indicate that the average delta(18)O composition of the Ordovician ocean, during nonglacial periods, was probably never more negative than -3 parts per thousand SMOW. Assuming an Ordovician seawater parts per thousand(18)O value of -1 parts per thousand SMOW, Holston Formation fibrous cements would have precipitated at temperatures between 27 and 36 degrees C, which is near the upper temperature limit for metazoans. A seawater delta(18)O value of -2 parts per thousand SMOW yields temperatures ranging from 23 to 31 degrees C, while a -3 parts per thousand SMOW value yields temperatures of 18-26 degrees C.

Procedures, based on their use as radiotracers for nuclear medicine imaging and for radiotherapy of cancer and other pathology, have become firmly established as important clinical modalities. It is estimated that on an annual basis in the United States alone, radionuclides are used medically in over 13 million imaging procedures, in over 100 million laboratory tests, and in an ever increasing number (>100,000) for therapeutic administrations. One out of every four hospital patients undergoes a procedure that involves the use of radionuclides. Diagnostic imaging methods using planar/single-photon emission computed tomography and positron-emission tomography (PET) imaging, as well as the measurement of in vivo organ function, physiology, or biochemistry, have become indispensable tools in patient workup and management. More than 80% of all imaging studies (mostly anatomic) currently use technetium 99m ((99)mTc), because it has turned out to be the ideal isotope from various considerations. However, over the past few years, nuclear medicine has experienced a slow but steady evolution towards functional studies, quantitative PET imaging, and novel therapeutic approaches. New radionuclides are required for these applications, and their development has attracted considerable interest. This article reviews the current status and future prospects for the development of many new potential isotopes. Practical issues, such as the feasibility of large-scale production and widespread availability in a continuous reliable fashion, are addressed. To date, the data are not sufficient to answer the question as to whether any of these radionuclides (or their applications, for that matter) will eventually assume as broad-based a role as that of (99)mTc. Nonetheless, there are a number of promising radionuclides that could assume an important place in the future practice of nuclear medicine. Copyright (C) 1996 by W.B. Saunders Company.

Previous studies have focused on the separation and removal of (TcO4-)-Tc-99 from high-level waste streams; however, little information is available for (TcO4-)-Tc-99 removal from only slightly contaminated groundwater. This paper describes treatment of (TcO4-)-Tc-99-contaminated groundwater with both batch and column flowthrough experiments. Synthetic resins and sponges, and zero-valence iron filings were used to evaluate their capacities and the rates of (TcO4-)-Tc-99 removal. The toxicity characteristic leaching procedure (TCLP) was applied to evaluate the leachability of Tc-99 adsorbed or co-precipitated on iron. Results suggest that both iron and synthetic resins remove (TcO4-)-Tc-99 from groundwater and that at a high flow rate (with residence time of less than 1 min), (TcO4-)-Tc-99 removal capacity is greater for iron filings than for the synthetic resins on a volume basis. Additionally, the rate of (TcO4-)-Tc-99 sorption on the sponge is slow (approximately 3 days), and the capacity is relatively low. No appreciable amount of Tc-99 can be leached out from the spent iron filings by the TCLP test. Overall, zero-valence iron filings provide fast reaction and high removal capacity for (TcO4-)-Tc-99 in groundwater. The high removal efficiency, low cost, and the small waste production of zero-valence iron are attractive for remediation of (TcO4-)-Tc-99-contaminated groundwater.

Activated carbon was used in both batch adsorption and column leaching studies. The adsorption experiments indicated that activated carbon adsorbs TcO4- selectively and effectively over a wide range of pH values and from various dilute electrolyte solutions (< 0.01 M). The partitioning coefficient (K-d) of TcO4- exceeded 27 000 ml/g when actual groundwater was used, and exceeded 12 000 ml/g when background solutions of 0.01 M CaCl2 and Na2SO4 were used. TcO4- removal efficiency was > 99% under these conditions, except in a 0.01 M NaNO3 background solution. Column studies confirmed a high adsorption capacity and selectivity of activated carbon for TcO4-. Within the detection limit, no Tc breakthrough was observed when more than 14 000 pore volumes of contaminated groundwater (containing similar to 3000 pCi Tc/l) were passed through a small column (6.6 x 30 mm) with 0.5 g activated carbon. Recovery of TcO4- from activated carbon was studied using various chemical reagents such as salicylate, phthalate, NaNO3, NaCl, and Na2SO4. Salicylate was found to be the most effective in desorbing and recovering the adsorbed TcO4- (as high as 100%). Therefore, the spent carbon can be disposed as low-level radioactive wastes or may be regenerated. Results of this work suggest that the use of activated carbon to remediate Tc-contaminated groundwater can be a promising technology - it is cost-effective and requires minimal installation and maintenance during the pump-and-treat processes.

The effectiveness of this technique at a particular site is dependent upon achieving and maintaining sufficient oxygen levels in the contaminated soil zones to support aerobic biodegradation. This paper uses analytic and numerical models of the gas flow in soil surrounding vents with simplified biodegradation relationships to predict the oxygen profiles in the soil under given site properties and operating conditions. The results may be used to decide whether bioventing is a feasible remediation technique at a particular site and to investigate the effects of vent placement and flow rate upon performance.

When the sparsity of A is to be exploited, the factorization is often preceded by a symbolic factorization step, which computes a data structure in which the nonzero entries of W and R are computed and stored. This is achieved by computing an upper bound on the nonzero structure of these factors, based solely on the nonzero structure of A. In this paper we use a well-known upper bound on the nonzero structure of W to obtain an upper bound on the nonzero structure of Q. Let U be the matrix consisting of the first n columns of Q. One interesting feature of the new bound is that the bound on W's structure is identical to the lower trapezoidal part of the bound on U's structure. We show that if A is strong Hall and has no zero entry on its main diagonal, then the bounds on the nonzero structures of W and U are the smallest possible based solely on the nonzero structure of A. We then use this result to obtain corresponding smallest upper bounds in the case where A is weak Hall, is in block upper triangular form, and has no zero entry on its main diagonal. Finally, we show that one can always reorder a weak Hall matrix into block upper triangular form so that there is no increase in the fill incurred by the QR factorization.

A chronosequence of restored tallgrass prairie was used to investigate the relationships between the formation of stable macroaggregates (> 212 mu m dial and the accrual of particulate and mineral-associated organic matter. Changes in the percentage of macroaggregates and in the accumulation of whole-soil organic C across the chronosequence were both described with a simple exponential model. The rate constant (k) for change in aggregation was more than 35 times the k for total organic C accumulation. Thus, the time required to reach 99% of equilibrium was 10.5 y for macroaggregates and 384 y for whole-soil organic C, providing evidence for the existence of a phased relationship between macroaggregate formation and C accrual. The input rate for whole-soil organic C to a IO-cm depth was estimated at 1.16 g kg(-1) y(-1) or 0.133 kg m(-2) y(-1) (assuming an average bulk density of 1150 kg m(-3) for previously cultivated soils in the chronosequence). An increase in macroaggregate-associated C-to-N ratios with time since cultivation suggested that the accumulating organic matter was not ''highly processed'', but less than 20% of the accrued C occurred in the form of particulate organic matter (density less than or equal to 1.85 g cm(-3)). Rather, most of the accumulated C occurred in the mineral-associated fraction of macroaggregates, suggesting that inputs of organic debris were rendered relatively rapidly into particles or colloids that are associated with mineral matter and thus are physically protected, slowing decomposition and promoting the development of stable microaggregates within macroaggregates.

We observed a very large anisotropy of the critical field B* extracted from ac-susceptibility data in accord with the enhanced ET-layer separation due to the large anions. The strong frequency dependence of B* reveals the weak pinning forces in the material. Magnetization and specific-heat, C, measurements prove the bulk effect of superconductivity. The linear coefficient of C is gamma approximate to 50 mJ/molK(2) which is a factor 9 larger than expected from a free-electron picture. Indications for strong coupling are found.

Milanovich, S.B. Brown, B.W. Colston, Jr., P.F. Daley and K. Langry, Talanta, 41 (1994) 2189], was used to provide analyses of TCE in laboratory tests of retardation of TCE in ground water. The sensor enabled inexpensive real time analyses of TCE in retardation tests conducted in a sand-filled flow-through column. The simultaneous data analysis of TCE, O-18 and Cl- breakthrough curves enabled the calculation of an estimated retardation coefficient which was found to be in good agreement with that predicted by the octanol/water partitioning K-d method. The fiber-optic sensor was demonstrated to be a fast and reliable method for conducting on-line laboratory analyses of TCE at the parts per billion level in a small volume of contaminated water, thus providing excellent temporal resolution of the data as well as minimizing volatile losses during sample collection and analysis.

A paradigm of multiple addition has appeared: as the number of H-2 addends increases, 1,4 addition becomes competitive with 1,2-addition. A significant chemical difference between singly-(buckytube) and doubly-(C-60) curved carbon is revealed by the energetics of Hz addition to the sidewalls vs. end-caps of a buckytube model. Remarkably, :CH2 insertion into either sidewalls or endcaps of buckytubes yields structures with similar heats of formation.

The derivation of the 'cubic law' is given as the solution to the Navier-Stokes equations for flow between smooth, parallel plates - the only fracture geometry that is amenable to exact treatment. The various geometric and kinematic conditions that are necessary in order for the Navier-Stokes equations to be replaced by the more tractable lubrication or Hele-Shaw equations are studied and quantified. In general, this requires a sufficiently low flow rate, and some restrictions on the spatial rate of change of the aperture profile. Various analytical and numerical results are reviewed pertaining to the problem of relating the effective hydraulic aperture to the statistics of the aperture distribution. These studies all lead to the conclusion that the effective hydraulic aperture is less than the mean aperture, by a factor that depends on the ratio of the mean value of the aperture to its standard deviation. The tortuosity effect caused by regions where the rock walls are in contact with each other is studied using the Hele-Shaw equations, leading to a simple correction factor that depends on the area fraction occupied by the contact regions. Finally, the predicted hydraulic apertures are compared to measured values for eight data sets from the literature for which aperture and conductivity data were available on the same fracture. It is found that reasonably accurate predictions of hydraulic conductivity can be made based solely on the first two moments of the aperture distribution function, and the proportion of contact area.

A subset of the trees was remeasured during 1994. Diameter increments, stem temperatures and soil water were also monitored. Respiration rates in the spring and summer of 1993 tracked growth rate increments, except during a drought when growth dropped to zero and respiration increased to its highest rate. During the dormant season, rates of total stem respiration (R(t)) tended to be greater in large trees with thick sapwood but no such trend was observed during the growing season. Before and after the growing season, respiration rates correlated well with stem temperatures. Estimated values of Q(10) were 2.4 for the two oak species and 1.7 for red maple. The Q(10) values were used along with baseline respiration measurements and stem temperatures to predict seasonal changes in maintenance respiration (R(m)). in red maple, annual total R(m) accounted for 56 and 60% of R(t) in 1993 and 1994, respectively. In chestnut oak, R(m) accounted for 65 and 58% of R(t) in 1993 and 1994, respectively. In white oak, R(m) accounted for 47 and 53% of R(t) in 1993 and 1994, respectively. Extrapolating these data to the stand level showed that woody tissue respiration accounted for 149 and 204 g C m(-2) soil surface year(-1) in 1993 and 1994, respectively.

However, the resulting surface flaws degrade strength-a serious concern component designers. An in situ reinforced silicon nitride, GS-44, was eroded in a slinger apparatus. Both transient (extremely low level) and steady-state erosion regimes were investigated. Alumina particles with effective average diameters of 140 mu m and 63 mu m were used at velocities of 50, 100, and 138 m/s. The biaxial tensile strength of the eroded specimens was measured. The strength decreased by about 15 percent after a very small erodent dosage and then remained virtually constant with further erosion. C1 ALLIED SIGNAL INC,MORRISTOWN,NJ 07962.

P. & R.] that form significant components of coastal ecosystems in the Pacific Northwest. Short-term (i.e., 2-hr) experiments showed that doubling CO2 resulted in up to a 2.5-fold increase in Zostera net apparent productivity (NAP). Nereocystis NAP was increased 2.2 - 2.8 fold. In experiments involving seven enrichment treatments, NAP increased with increasing CO2 between ambient (1.0x) and 2.5x CO2 in both Zostera and Nereocystis. Nereocystis acid Zostera NAP was lowest at highest (i.e., 5x) CO2 concentrations. In growth experiments, mean growth rate of Zostera increased with increasing CO2 during one of the two trials. I conclude that increasing CO2 in the surface waters of the coastal ocean would predictably result in increased NAP of these two species. These results supplement limited published data showing that shallow estuarine and marine systems are vulnerable to increased carbon dioxide.

The study seeks to identify the more important impacts of medium heterogeneity, as embodied in spatially variable physical and chemical properties, on the migration and dilution rates of a model cocontaminant mixture, as well as on the overall partitioning among the aqueous and solid species formed from complexation and sorption reactions. Solid phase reactions are considered to occur on hydrous-ferric oxide (goethite) coatings on the sand and are controlled by the abundance of the oxide as a function of the specific sand surface area and larger-scale patterns of oxide deposition. The simulations involve calculation of fluid flow and chemical migration within highly resolved, two- and three-dimensional regions with synthetic material properties that approximate observed conditions in a sandy coastal aquifer. Model simulations in this system indicate that (1) the impact of correlation between reactive surface area and hydraulic conductivity, although evident, seems much less significant than the overall abundance and distribution of the reactive area, such as the kind of banded goethite patterns observed in a coastal sand body; (2) strong multicomponent interactions clearly reinforce the need to treat the mixture as a coupled system, as opposed to a series of independently reactive compounds; (3) simplifications can be made in extremely dilute problems that allow retardation effects to become concentration independent; and (4) for nonlinear reaction problems, three-dimensional models will be more appropriate than two-dimensional models to the extent that dispersion in the added dimension accelerates chemical dilution rates.

The LNAPL pool is located in a capillary fringe, and the bottom of the pool is in direct contact with the aquifer. In the LNAPL pool, SWSCs are assumed to move by liquid diffusion, and within the aquifer by mass flow under the influence of steady horizontal groundwater flow. The dissolution process along the LNAPL/water interface assumed a local phase equilibrium relation. A formal analytical solution to the mathematical model was first derived in the Laplace transform domain and inverted numerically by means of the Bellman algorithm. This solution was used to calculate the dissolution of a SWSC from an LNAPL pool to groundwater and to identify physicochemical factors that could significantly affect this transient mass transfer process. Results show that within the range of parameters we used in the study, the SWSC flux, which is represented by the modified Damkohler number <(Da(t))over bar>, can be related to the Fourier number F-o the transverse hydrodynamic Peclet number Pe(T), and the ratio of nonaqueous diffusion Peclet number Pe(N) to Pe(T) (or D-T/D-N) through a simple power law relationship.

CHARGED-PARTICLE MULTIPLICITY; E+E ANNIHILATION; ROOT-S; 3-JET EVENTS; ALPHA-S; LEP; DISTRIBUTIONS; ALGORITHMS; COLLIDER; QCD AB Three jet events arising from decays of the Z beson, collected by the DELPHI detector, were used to measure differences in quark and gluon fragmentation. Gluon jets were anti-tagged by identifying b quark jets. Unbiased quark jets came from events with two jets plus one photon. Quark and gluon jet properties in different energy ranges were compared for the first time within the same detector. Quark and gluon jets of nearly the same energy in symmetric three jet event topologies were also compared. Using three independent methods, the average value of the ratio of the mean charged multiplicities of gluon and quark jets is [ r ] = 1.241 +/- 0.015 (stat.) +/- 0.025 (syst.). Gluon jets are broader and produce fragments with a softer energy spectrum than quark jets of equivalent energy. The string effect has been observed in fully symmetric three jet events. The measured ratio R(gamma) of the charged particle flow in the inter-jet region of the and < q (q) over bar gamma> samples agrees with the perturbative QCD expectation. The dependence of the mean charged multiplicity on the hadronic center-of-mass energy was analysed in photon plus n-jet events. The value for alpha(s)(M(z)) determined from these data using a QCD prediction with corrections at leading and next-to-leading order is alpha(s)(M(z)) = 0.116 +/- 0.003 (stat.) +/- 0.009 (syst.).

We show that the algebra of functions and the differential calculus on the sphere are covariant under the coaction of fractional transformations with SUq(2) coefficients as well as under the action of SUq(2) vector fields. Going to the classical limit we obtain the Poisson sphere. Finally, we study the invariant integration of functions on the sphere and find its relation with the translationally invariant integration on the complex quantum plane.

Sigma(0) and Omega(-) in Z decays SO ZEITSCHRIFT FUR PHYSIK C-PARTICLES AND FIELDS LA English DT Article ID E+E AB Reconstructed ii baryon decays and photon conversions in DELPHI are used to measure the Sigma(0) production rate from hadronic Z(0) decays at LEP. The number of Sigma(0) decays per hadronic Z decay is found to be: > = 0.070 +/- 0.010 (stat.) +/- 0.010 (syst.). The Omega(-) production rate is similarly measured to be: = 0.0014 +/- 0.0002 (stat.) +/- 0.0004 (syst.) by a combination of methods using constrained fits to the whole decay chain and particle identification.

We find no measurable difference between R(p) and R(d). Our results are consistent with, and more precise than, previous SLAG data. At high x, R is somewhat larger than order alpha(s)(2) pQCD predictions, even when target mass effects are included. C1 CONTINUOUS ELECTRON BEAM ACCELERATOR FACIL CTR,NEWPORT NEWS,VA 23606.

the diffractive cross section in deep inelastic scattering SO ZEITSCHRIFT FUR PHYSIK C-PARTICLES AND FIELDS LA English DT Article ID LUND MONTE-CARLO; JET FRAGMENTATION; POMERON STRUCTURE; EP SCATTERING; E+E-PHYSICS; CALORIMETER; HERA; ZEUS; DISTRIBUTIONS; SINGULARITY AB Diffractive scattering of gamma*p --> X + N, where N is either a proton or a nucleonic system with M(N) < 4 GeV has been measured in deep inelastic scattering (DIS) at HERA. The cross section was determined by a novel method as a function of the gamma*p c.m, energy W between 60 and 245 GeV and of the mass M(X) of the system X up to 15 GeV at average Q(2) values of 14 and 31 GeV2. The diffractive cross section d sigma(diff)/dM(X) is, within errors, found to rise linearly with W. Parameterizing the W dependence by the form d sigma(diff)/dM(X) proportional to (W-2)((2<(alpha?(IP))over bar>-2)) the DIS data yield for the pomeron trajectory <(alpha(IP))over bar> = 1.23 +/- 0.02(stat) +/- 0.04(syst) averaged over t in the measured kinematic range assuming the longitudinal photon contribution to be zero. This value for the pomeron trajectory is substantially larger than <(alpha(IP))over bar> extracted from soft interactions. The value of measured in this analysis suggests that a substantial part of the diffractive DIS cross section originates from processes which can be described by perturbative QCD. From the measured diffractive cross sections the diffractive structure function of the proton F-2(D(3))(beta,Q(2),x(IP)) has been deterz mined, where beta is the momentum fraction of the struck quark in the pomeron. The form F-2(D(3)) = constant .(1/x(IP))(a) gives a good fit to the data in all beta and Q(2) intervals with a = 1.46 +/- 0.04(stat) +/- 0.08(syst). C1 ANDREWS UNIV, BERRIEN SPRINGS, MI 49104 USA.

The PHSC equation of state uses a hard-sphere-chain reference system plus a van der Waals attractive perturbation. Three pure-component parameters are obtained from readily available thermodynamic properties. Mixture parameters are obtained using pure-component parameters, conventional combining rules, and one or two binary constants. Theoretical and experimental coexistence curves and miscibility maps show good agreement for selected blends containing polymers and copolymers. For LLE of dilute or semi-dilute solvent/polymer solutions, it is necessary to decrease the pure-component polymer chain length in the perturbation term, probably because the mean-field approximation is not suitable for such solutions.

Some copolymer+polymer mixtures are miscible although their corresponding homopolymers are not miscible; for example, over a range of acrylonitrile content, styrene/acrylonitrile copolymers are miscible with poly(methyl methacrylate) but neither polystyrene nor polyacrylonitrile is miscible with poly(methyl methacrylate). Similarly, over a composition range, butadiene/acrylonitrile copolymers are miscible with poly(vinyl chloride) while none of the binary combinations of the homopolymers [polybutadiene, polyacrylonitrile, and poly(vinyl chloride)] are miscible. This behavior has been attributed to ''intramolecular repulsion'' between unlike copolymer segments. We have observed similar behavior in vapor-liquid equilibria (VLE) of copolymer+solvent systems. We find that acrylonitrile/butadiene copolymers have higher affinity for acetonitrile solvent than do polyacrylonitrile or polybutadiene. We attribute this non-intuitive behavior to ''intramolecular repulsion'' between unlike segments of the copolymer. This repulsive interaction is weakened when acetonitrile molecules are in the vicinity of unlike copolymer segments, favoring copolymer+solvent miscibility. We find similar behavior when acetonitrile is replaced by methyl ethyl ketone. To our best knowledge, this effect has not been reported previously for VLE. We have obtained VLE data for mixtures containing a solvent and a copolymer as a function of copolymer composition. It appears that, at a given solvent partial pressure, there may be copolymer composition that yields maximum absorption of the solvent. This highly non-ideal VLE phase behavior may be useful for optimum design of a membrane for a separation process. C1 UNIV CALIF BERKELEY,DEPT CHEM ENGN,BERKELEY,CA.

The evolution of the structure was studied by various techniques, including slip line studies, global texture measurements, backscattered electron Kikuchi patterns and TEM. Intense shear banding was observed at large strains and is related to the texture evolution. The mechanical behaviour was interpreted in terms of work hardening rate vs. stress plots (or theta/tau plots). Increasing the temperature leads to a decrease of the initial slope of the theta/tau plot as well as an increase in its concavity. At large strains all materials exhibited a stage of constant work hardening at low rate, or stage IV. The addition of solute was shown to result in an increase of the work hardening rate, which could be represented by a translation of the theta/tau plot on the stress axis. Phenomenological models are proposed for the prediction of the influence of temperature and solute content on work hardening.

Nitrogen has greater solid-solubility than carbon, is a strong austenite stabilizer, potent interstitial solid-solution strengthener, and improves pitting corrosion resistance. Although the solubility of nitrogen in liquid iron is very low, 0.045 wt.% at 1600 degrees C and atmospheric pressure: nitrogen levels above 1 wt.% can be obtained through alloying and specialized high-pressure melting techniques. An austenitic stainless steel should be considered ''high-nitrogen'' if it contains more nitrogen than can be retained in the material by processing at atmospheric pressure; for most alloys, this limit is approximately 0.4 wt.%. This article describes melting and processing technologies applicable to high-nitrogen steels and the effects of interstitial nitrogen on a variety of material properties. Thermal stability, nitride precipitation kinetics, and the effects of nitride formation on mechanical properties and corrosion resistance are discussed.

This study explores the effect of varying the alloy composition on yield strength and tries to separate the interstitial nitrogen strengthening contributions from the substitutional solution strengthening. Statistical analysis was conducted on the yield strength of stainless steel compositions with significantly different chromium, nickel, and manganese concentrations as a function of nitrogen concentration and temperature. Two different nitrogen strengthening mechanisms have previously been reported: (i) matrix strengthening due to the presence of interstitial nitrogen; (ii) dislocation drag resulting from nitrogen being carried along with the dislocation as it moves through the lattice. Both strengthening mechanisms were found to be a strong function of nitrogen concentration but were essentially independent of the character and the amount of metallic elements in the alloy. The principal effect of varying the chromium, manganese, and nickel concentration in the stainless steel compositions was to increase the nitrogen solubility. Varying the composition did little to improve strength. C1 CLEMSON UNIV,DEPT MECH ENGN,CLEMSON,SC 29634. RP Rawers, J (reprint author), US BUR MINES,ALBANY RES CTR,ALBANY,OR 97321, USA.

With the development of instrumental techniques with low detection limits, such as inductively coupled plasma-mass spectrometry (ICP-MS), attention is shifting toward achieving faster and more elegant ways of oxidizing the organic material inherent in environmental samples. Closed-vessel microwave dissolution was compared with conventional methods for the determination of concentrations of cerium, samarium, europium, terbium, uranium, and thorium in a series of samples from the National Institute of Standards and Technology and from fields in Idaho. The ICP-MS technique exhibited detection limits in parts-per-trillion and linear calibration plots over three orders of magnitude for the elements under study. The results obtained by using nitric acid and hydrogen peroxide in a microwave digestion system for the analysis of reference materials showed close agreement with the accepted values. These values were compared with results obtained from dry- and wet-ashing procedures. The findings from an experiment comparing radiometric techniques for the determination of actinide elements to ICP-MS are reported. C1 ARGONNE NATL LAB,DIV CHEM TECHNOL,ARGONNE,IL 60439.

The properties of this feature, unusual in chromatography, are discussed. An analytical solution for the profile of this boundary is derived. It is valid in the case of fast mass transfer kinetics. It explains clearly the formation and stability of this steady-state concentration profile and the influence on its width of axial dispersion and the mass transfer kinetics. Numerical calculations of this steady-state profile were also carried out for the sake of comparison. The results of this study suggest that a similar phenomenon may take place in simulated moving bed operation. They improve our understanding of the counter-current moving bed and simulated moving bed processes in chromatography. C1 UNIV TENNESSEE,DEPT CHEM,KNOXVILLE,TN 37996.

The presence of these additives in organic-water mixtures greatly improves the separation of alkylbenzenes, polycyclic aromatic hydrocarbons, alkylphenols, and some other aromatic compounds. Compared with separations obtained without additives, shorter retention times and sharper peaks are obtained. The reason for the improvement appears to be a stronger interaction between the analyte molecules and the mobile phase due to the presence of long hydrocarbon chain(s) or polyoxypropylene segments in the additive molecules. The retention times of late-eluting compounds are reduced by a larger percentage than the retention times of earlier peaks. This effect is similar to that obtained with gradient elution but here only isocratic elution with an organic-water eluent containing an appropriate additive is used. Solvent strength and selectivity can be varied by controlling the type and concentration of the additive. Binding constants between solute and surfactant additives were calculated by relating capacity factor to surfactant concentration. C1 IOWA STATE UNIV SCI & TECHNOL,US DOE,AMES LAB,AMES,IA 50011.

The relative ability of several solvents to elute polynuclear aromatic hydrocarbons in solid-phase extraction was determined.

To test this hypothesis, we synthesized a B-10-enriched nitroimidazole, 1-[2-[(undecahydro-close-dodecaborato)thio]ethyl]-2-methyl-5-nitroimidazole (imidocaptate), by coupling the Cs salt of BSH (Cs-2-(B12H11SH)-B-10) with 1-(2-bromoethyl)-2-methyl-5-nitroimidazole followed by purification of the adduct. Imidocaptate was taken up by V-79 cells in culture and showed no inherent toxicity under euoxic conditions up to 1.05 mM (126 mu g of B-10/mL of culture medium). Imidocaptate showed a dose-dependent decrease in Do when the treated cells were irradiated with a thermal neutron beam. At the highest dose tested (126 mu g of B-10/mL of culture medium), the ratio of control to sample D-0 values was 2.6 for both linear quadratic and single-hit multitarget models. At 33 mu g of B-10/mL, imidocaptate showed a control/treated D-0 ratio (1.5) equal to that observed with the disulfide form of BSH at 28 mu g of B-10/mL, Compared to BSH and its disulfide, the reduced toxicity and equipotency of imidocaptate suggest that this agent may be useful for boron neutron capture therapy of cancer.

These data were compared with measures obtained from nine previously studied normal men who had received no drug intervention. Although a previously published study had demonstrated significantly decreased metabolism in whole brain, neocortex, limbic cortex, thalamus, and caudate nucleus 12 h after a 5-mg dose of haloperidol, the present 2-h study did not show significant metabolic changes despite the fact that significant extrapyramidal effects occurred. Taken together, these studies demonstrate differences in the temporal organization of behavioral and metabolic responses to haloperidol challenge. C1 NYU,MED CTR,DEPT PSYCHIAT,NEW YORK,NY 10016.

We used logistic regression to determine the relationship of cocaine usage to neuropsychological test performance. We compared 38 patients with an average of 3.6 (SD = 2.5) years of crack cocaine use and 24.5 (SD = 28.1) days of abstinence to 54 normal volunteers on a battery of neuropsychological tests. Statistical. adjustments were made for the effects of age, education, socioeconomic class, and level of depression. Our findings were mixed with regard to purported measures of executive/frontal functioning, with worse performance associated with cocaine usage on the Booklet Categories Test, but better performance associated on others (number of categories on the Wisconsin Card Sorting Test, Controlled Oral Word Association). Cocaine usage was associated with impairment on measures of spatial, but not verbal memory, confrontation naming, and Trail-making Test, Part B, a measure of perceptual-motor speed and cognitive flexibility. In summary, it appears that continuous crack cocaine use produces a dissociative pattern in neuropsychological test performance with improvement on some measures, but deterioration on others. The permanence of these effects remains to be determined with longitudinal studies. C1 SUNY STONY BROOK,DEPT PSYCHIAT,HSC,STONY BROOK,NY 11794. DARTMOUTH COLL SCH MED,DEPT PSYCHIAT,HANOVER,NH 03758.

When hyperpolarized xenon-129 is dissolved in liquids, a time-dependent departure of the proton spin polarization from its thermal equilibrium is observed, The variation of the magnetization is an unexpected manifestation of the nuclear Overhauser effect, a consequence of cross-relaxation between the spins of solution protons and dissolved xenon-129. Time-resolved magnetic resonance images of both nuclei in solution show that the proton magnetization is selectively perturbed in regions containing spin-polarized xenon-129. This effect could find use in nuclear magnetic resonance spectroscopy of surfaces and proteins and in magnetic resonance imaging. C1 UNIV CALIF BERKELEY,DEPT CHEM,BERKELEY,CA 94720.

By variation of the concentration of the colloidal suspensions, slides with different interparticle distances were obtained, and their extinction spectra were measured in water. A blue shift (up to 90 nm) and sharpening of the peak corresponding to the plasmon resonance was observed as the distance between particles decreased to a value comparable to, or less than, their diameter. The angular dependence of the extinction spectra was studied for s- and p-polarized light. The data are interpreted to result from coherent coupling of the plasmon resonances in closely spaced silver particles upon irradiation with light.

This method employs an axial quadrupolar dc pulse (1 mu s) to force all ions into coherent radial motion; ions of the same mass-to-charge ratio are either in phase or phase-shifted by exactly 180 degrees. After this activating pulse, the ions continue to oscillate at their secular frequency in a coherent fashion so that ions of the same mass-to-charge ratio simultaneously cross the z-axis (r = 0) twice per secular cycle. At this specific moment, a single-pulse, (15 ns) laser beam, aligned collinear with the z-axis, can be used to improve the photodissociation efficiency by irradiating these ions that are radially focused along the z-axis and within the confines of the laser beam. The length of the delay time between the dc pulse and the laser pulse is critical, as it controls the phase, and hence the spatial position, of the ions when the laser is fired. Under the given operating conditions, this method improves the photodissociation efficiency from 9% to 35%. The photodissociation efficiency steadily decreases with longer delay times as the oscillating ions undergo increasing numbers of collisions with the helium buffer gas and lose coherence. Since the secular frequencies of trapped ions are mass-dependent at a fixed rf amplitude, ions of different mass-to-charge ratios will cross the z-axis at different times. Mass-selective photodissociation is illustrated for a mixture of benzoyl-h(5) and -d(5) cations by appropriately adjusting the delay time between the dc pulse and the laser pulse. Simulations using the program ITSIM were used to design this experiment, and the data which describe the ion motion are provided. C1 PURDUE UNIV,W LAFAYETTE,IN 47907.

Low-power, laser desorption Fourier transform mass spectrometry (LD-FTMS) of the product yielded two ions at m/z = 1539 and 1556, which correspond to [C-60(cyclohexane)(10)-xH](+) for x = 23 and 6, respectively. Higher power laser desorption conditions as well as collision-induced dissociation experiments of selected ions show the sequential loss of cyclohexene (C6H10) units. Small-angle X-ray scattering (SAXS) of the dissolved material supports the mass spectrometry results of cyclohexane additions to the sphere. Taken together, the mass spectrometry and SAXS data indicate that the identity of the gamma-radiolysis products of C-60 in cyclohexane most likely are cyclohexyl adducts of C-60, primarily Cao(cyclohexane)(10). The SAXS data further indicate that some of the C-60(C6H12)(x) entities aggregate into dimers in solution. A model is proposed in which cyclohexyl and hydrogen atom radiolysis products attach to C-60 across double bonds. These double bonds are possibly those associated with the two top and bottom 5-fold symmetry positions around two opposing pentagons. C1 OAK RIDGE NATL LAB,OAK RIDGE,TN 37831.

Both techniques show the existence of a hexagonal close-packed adlayer phase above a critical potential and are in good quantitative agreement on the adlayer structural parameters. The bromide-bromide spacing changes continuously between 4.24 Angstrom at the critical potential and 4.03 Angstrom at a potential 300 mV more positive. The adlayer is rotated relative to the substrate by an angle dependent on potential and bromide concentration. The potential-dependent adlayer density corresponding to these structural results agrees well with Br surface excess densities from published electrochemical measurements. At very positive potentials a bromide-induced step-flow etching of the Au substrate is observed. The results are used to compare the different techniques and to discuss the adlayer structure, the phase behavior, and the halide-gold chemical interaction.

The beats were studied as a function of (n) over bar, the mean principal quantum number passed by the Rydberg analyser.

A physical model for capture/excitation to high Rydberg states is presented which is consistent with these results. C1 INST PHYS & CHEM RES,ATOM PHYS LAB,WAKO,SAITAMA 35101,JAPAN.

A complementary DNA clone encoding a part of the human type II cGMP-dependent protein kinase was isolated from a cerebellum library. Based on sequence information from this complementary DNA, the 5'-end of the type II cGMP-dependent protein kinase was amplified from human brain messenger RNA using polymerase chain reaction. The composite complementary DNA encoded a 762 amino acid protein with a calculated molecular mass of 87.4 kDa. Messenger RNAs encoding the type II cGMP-dependent protein kinase were detected in small intestine, colon and prostate. By using polymerase chain reaction and Southern blotting on somatic cell hybrids, the gene encoding the type II cGMP-dependent protein kinase was mapped to human chromosome 4 q13.1-q21.1.

We have used this apparatus to follow the reaction of dioxygen with bovine cytochrome c oxidase following photolysis of the fully reduced CO ligated enzyme up to a dioxygen concentration of 16 mM. The observed rate dependence on [O-2] follows saturation kinetics and was fit to a limiting rate of 1.0 x 10(6) s(-1).

In contrast to other known mu-oxo systems of technetium or ruthenium, the cyclic voltammetric data of [(N5Tc)(2)O](4+) suggests a relatively weak metal-metal interaction, however the visible absorption spectrum and the apparent magnetic properties suggests that this interaction cannot be completely dismissed.

Mild chemical oxidation of Tc2Cl4(PMe(2)Ph)(4) with ferrocenium hexafluorophosphate in acetonitrile produces [Tc2Cl4(PMe(2)Ph)(4)][PF6] (1) in 82% yield. One-electron oxidation of Tc2Cl4(PMe(2)Ph)(4) by ferrocenium hexafluorophosphate in the presence of ppnCl (ppn = bis(triphenylphosphine)iminium) yielded the neutral compound Tc2Cl5(PMe(2)Ph)(3) (2) in 89% yield. Both species are paramagnetic, as evidenced by EPR spectroscopy, and possess a sigma(2) pi(4) delta(2) delta* ground state electronic configuration on the basis of structural and spectroscopic data. The solid state structures of three forms of 1 have been investigated by X-ray crystallography together with the structure of 2. The crystallographic parameters for these structures are as follows: [Tc2Cl4(PMe(2)Ph)(4)][PF6] (1a, orthorhombic form), C222(1) with a = 9.448(1) Angstrom, b = 24.299(1) Angstrom, c = 18.231(1) Angstrom, V = 4185.4(6) Angstrom(3), and Z = 4; [Tc2Cl4(PMe(2)Ph)(4)][PF6] (1b, monoclinic form), P2(1)/n with a = 12.799(4) Angstrom, b = 18.254(2) Angstrom, c = 17.945(5) Angstrom, beta = 96.39(1)degrees, V = 4166(2) Angstrom(3), and Z = 4; [Tc2Cl4(PMe(2)Ph)(4)][PF6]. 1/2THF (1 . 1/2THF), P2(1)/c with a = 10.580(3) Angstrom, b = 33.327(3) Angstrom, c = 13.861(5) Angstrom, beta = 111.04(2)degrees, V = 4562(1) Angstrom(3), and Z = 4; Tc2Cl5(PMe(2)Ph)(3) (2), P2(1)/c with a = 11.134(1) Angstrom, b = 14.406(1) Angstrom, c = 19.501(5) Angstrom, beta = 98.144(6)degrees, V = 3096.3(7) Angstrom(3), and Z = 4. The cation in 1 is the 1,3,6,8-isomer, and the molecule in 2 is the 1,3,6-isomer. The Tc-Tc bond lengths for 1a, 1b, 1 . 1/2THF, and 2 (2.1092(9), 2.106(1), 2.1073(8), and 2.1092(4) Angstrom, respectively) are slightly shorter than those of the corresponding Tc2Cl4(PR(3))(4) complexes, consistent with the removal of one electron from a delta* orbital. Electrochemical studies reveal that both compounds are capable of undergoing a one-electron oxidation and a one-electron reduction to yield the respective Tc-2(6+) and Tc-2(4+) dinuclear cores.

Between 1 bar and 1.5 kbar, the crystal structure changes to one almost identical to that of the corresponding hydrogenous compound at 1 bar. The structural change involves a 90 degrees switch in the direction of the long bonds of the Cu(D2O)(6)(2+) ion, accompanied by a change in the hydrogen-bonding interactions of the ammonium cations. Comparison of these two structures with those at similar to 15 K shows that at room temperature, for both the high (H) and low (L) pressure phases, the Cu complexes are in thermal equilibrium with the other structural isomer. Though one of these is energetically preferred in the H and the other in the L phase, the variation of the powder EPR spectrum with pressure indicates a continuous transition between both within similar to 1 kbar and suggests that at similar to 0.5 kbar the two orientations of the copper complex are similar in energy. However, the underlying thermally induced equilibrium is little affected by pressure, and this is also the case for the Cu(H2O)(6)(2+) ion in Cu2+-doped K-2[Zn(H2O)(6)](SO4)(2). The crystal structure of K-2[Cu(H2O)(6)](SO4)(2) at 15 K and 1.4 kbar, determined by time-of-flight neutron diffraction, is similar to that at 295 K and 1 bar, except for indications that here also a thermal population of the higher energy form in which the directions of the long and intermediate Cu-O bonds interchange occurs at 295 K. The powder EPR spectrum of the potassium salt at 295 K shows little change between 1 bar and 11 kbar. C1 UNIV TASMANIA,DEPT CHEM,HOBART,TAS 7001,AUSTRALIA.

Calculation of pM values (pM = -log [M]) show that L has the highest reported binding affinity for cadmium relative to other [2.2.2] polyoxa-polyaza cryptates. Two cadmium cryplate complexes, [CdL](BF4)(2) (1a) and [CdL](OAc)(2) . 2H(2)O (1b), were synthesized by metalation of the free cryptand. The molecular structures of compounds 1a and 1b were determined by X-ray diffraction. Crystallographic data for 1a: trigonal, , Z = 2, a = 9.581(2) Angstrom, c = 17.003(4) Angstrom, V = 1351.2(5) Angstrom(3). Crystallographic data for 1b: monoclinic, C2/c, Z = 4, a = 10.500(2) Angstrom, b = 14.782(3) Angstrom, c = 19.395(4) Angstrom, beta = 99.30(2)degrees, V = 2971(1) Angstrom(3). The cadmium ions in both complexes are eight-coordinate and display similar coordination geometries but different ligand conformations, designated as parallel and oblique. The cadmium coordination sphere is best described as a bicapped octahedron. Through 2D NMR experiments we have found that the Cd is in a symmetric environment and the conformation of the ligand in solution is consistent with the parallel conformation observed in one of the solid state structures. The Cd-113 NMR shift of this eight-coordinate amine complex is 75 ppm relative to 0.1 M aqueous Cd(ClO4)(2), which correlates with shifts observed for other [2.2.2] cadmium polyoxa-polyaza cryptates.

Measurements were made near 1 atm of total pressure of ethylene and hydrogen and at 295 K. Kinetic information was obtained simultaneously with the surface vibrational spectroscopy by monitoring the reaction rate with gas chromatography. The macroscopic turnover rate and surface adsorbate concentration could then be correlated. During the reaction ethylidyne, di-sigma-bonded ethylene, ethyl, and pi-bonded ethylene were observed on the surface in various amounts depending on conditions. Ethylidyne, a spectator species during hydrogenation, competed directly for sites with di-sigma-bonded ethylene and its surface concentration could be shown to be completely uncorrelated with the rate of hydrogenation. In contrast, pi-bonded ethylene did not compete for sites with the ethylidyne overlayer and was observed on the surface regardless of the surface concentration of ethylidyne. Evidence points to the pi-bonded species as being the primary intermediate in ethylene hydrogenation on Pt(111). The surface concentration of this species is about 0.04 ML (ML = monolayer) during reaction. Thus, the turnover rate per reaction intermediate is 25 times faster than the turnover rate if measured per surface platinum atom. C1 UNIV CALIF BERKELEY,DEPT CHEM,BERKELEY,CA 94720.

The ordering in these SAMs arises from the competition of bonding to the surface and mutual steric effects that force alignment of the dipolar chromophores.

The radiosensitivity and defective repair phenotype are complemented by the 80-kDa subunit of the Ku protein. We determined the nature of the mutations that develop spontaneously at the hprt locus in this cell line using both multiplex PCR deletion screening and DNA sequencing. Ninety-two independent spontaneous mutants were analyzed and the results were compared to the mutation spectrum of 64 previously analyzed hprt spontaneous mutants isolated from the parental CHO-K1 cell line. More than 50% of the spontaneous xrs-5 mutants had lost one or more exons while less than 25% of spontaneous CHO-K1 mutants had lost one or more exons. Most of the deletions in xrs-5 cells involved the loss of multiple exons while single exon deletions predominated in CHO-K1. There was also a nonrandom distribution of breakpoints in both CHO-K1 and xrs-5. Most of the deletion breakpoints were 3' to exon 9, around exons 4-6, or near exon 1. Although the frequency of base substitutions was lower in xrs-5, the spectrum of base substitutions was qualitatively similar to that of CHO-K1. There was no significant difference in the spontaneous mutant frequency in xrs-5 and CHO-K1. The results suggest that in certain regions of the hprt gene, base alterations can be converted to large deletions, and that alterations in the Ku protein complex can influence this process.

Deformations of the drop and the flow fields are determined by solving the nonlinear free-boundary problem composed of the Navier-Stokes system governing the flow field and Laplace's system governing the electric field. The solutions are obtained by using the Galerkin finite-element method with an elliptic mesh generation scheme. Under conditions of creeping flow and vanishingly small drop deformations, the results of finite-element computations recover the asymptotic results. When drop deformations become noticeable, the asymptotic results are often found to underestimate both the flow intensity and drop deformation. By tracking solution branches in parameter space with an are-length continuation method, curves in parameter space of the drop deformation parameter D versus the square of the dimensionless field strength E usually exhibit a turning point when E reaches a critical value E(c). Along such a family of drop shapes, steady solutions do not exist for E > E(c). The nonlinear relationship revealed computationally between D and E(2) appears to be capable of providing insight into discrepancies reported in the literature between experiments and predictions based on the asymptotic theory. In some special cases with fluid conductivities closely matched, however, drop deformations are found to grow with E(2) indefinitely and no critical value E(c) is encountered by the corresponding solution branches. For most cases with realistic values of physical properties, the overall electrohydrodynamic behaviour is relatively insensitive to effects of finite;Reynolds-number flow. However, under extreme conditions when fluids of very low viscosities are involved, computational results illustrate a remarkable shape turnaround phenomenon: a drop with oblate deformation at low field strength can evolve into a prolate-like drop shape as the field strength is increased.

An undeformed Kelvin cell has six planar quadrilateral faces with curved edges and eight non-planar hexagonal faces with zero mean curvature. The elastic-plastic response of the foam is modelled by determining the bubble shape that minimizes total surface area at each value of strain. Computer simulations were performed with the Surface Evolver program developed by Brakke. The foam structure and macroscopic stress are piecewise continuous functions of strain. Each discontinuity corresponds to a topological change (T1) that occurs when the film network is unstable. These instabilities involve shrinking films, but the surface area and edge lengths of a shrinking film do not necessarily vanish smoothly with strain. Each T1 reduces surface energy, results in cell-neighbour switching, and provides a film-level mechanism for plastic yield behaviour during foam flow. The foam structure is determined for all strains by choosing initial foam orientations that lead to strain-periodic behaviour. The average shear stress varies by an order of magnitude for different orientations. A Kelvin foam has cubic symmetry and exhibits anisotropic linear elastic behaviour; the two shear moduli and their average over all orientations are G(min) = 0.5706, G(max) = 0.9646, and (G) over bar = 0.8070, where stress is scaled by T/V-1/3, T is surface tension, and V is bubble volume. An approximate solution for the microrheology is also determined by minimizing the total surface area of a Kelvin foam with flat films. C1 SANDIA NATL LABS,ENGN SCI CTR,ALBUQUERQUE,NM 87185.

HoNiBC exhibits antiferromagnetic ordering of the Ho moments with a simple commensurate magnetic structure below T-N = 10 K. The magnetic unit cell, doubled along the c-direction with respect to the chemical unit cell, consists of ferromagnetic planes antiferromagnetically coupled along the c-axis. On the other hand, the Er moments in ErNiBC show ferromagnetic ordering with a Curie temperature of 4.5 K. In contrast to the case for the structurally related superconducting counterparts (HoNi2B2C and ErNi2B2C) no modulated magnetic structures were observed for any temperatures above 1.4 K.

The Q(t) values from the data decrease sharply over the rotational frequency range 0.3 to 0.5 MeV (I = 20 to 32 (h) over bar). At the same rotational frequencies the kinematic moment of inertia is nearly constant, increasing slightly at the higher frequencies <(h)over bar omega> = 0.40 to 0.55 MeV. These observations can be understood qualitatively as a rotationally-induced deoccupation of strongly shape polarizing anti-aligned high-j, low-Omega orbitals i.e., those in which the nucleons are moving in the opposite direction to the rotation. A summary of the Q(t) values extracted from the lifetime data for the yrast decay sequences of the even-A nuclei Yb-160-168 are compared with the deformations from self-consistent cranking TRS calculations. The TRS calculations show the expected neutron number dependence, i.e., Delta beta(2)/beta(2)(<(h)over bar omega> = 0) is smaller with increasing N and the corresponding loss of collectivity, Q(t) vs <(h)over bar omega>, has a smaller slope at the larger <(h)over bar omega> with increasing N. For Yb-164,Yb-166,Yb-168 the loss of collectivity from the DBLS measurements occurs at higher <(h)over bar omega> than predicted and the slope of Q(t) vs <(h)over bar omega> is much larger than predicted, The enhanced E1/E2 branching ratios and the large transition dipole moments for decay of the states in the (-, 1) band to the ground band and the (+, 0) band in Yb-164 suggest an octupole instability for Yb-164.

Nevertheless, a macroscopic normal conductor can experience no Aharonov-Bohm (AB) effect. That is proved by assuming only that a normal conductor lacks off-diagonal long-range order (ODLRO), which means that the electrons lack long-range phase coherence. Then by restricting the Hilbert space to density matrices which lack ODLRO, one can introduce a restricted gauge transformation that removes the interaction of the conductor with the vector potential. Consequently, the AB effect on a beam particle is not shielded by the conductor. RP Peshkin, M (reprint author), ARGONNE NATL LAB,DIV PHYS,ARGONNE,IL 60439, USA.

Energy released by bond breaking accumulates in a local phonon field that moves with the crack tip and promotes the emission of dislocations. Branching follows dislocation emission along a slip plane. The branching instability requires the crack to achieve a critical velocity, as well as an induction time for energy buildup at the crack tip.

This approach probes a close to ideal random walk problem, free from perturbations such as electric fields, mechanical stresses, or chemical potentials. The Ga self-diffusion coefficient in intrinsic GaAs can be well described with D = (43 +/- 25) exp[(-4.24 +/- 0.06 eV)/k(B)T] over 6 orders of magnitude between 800 and 1225 degrees C under As-rich condition. No significant doping effects are observed in samples with their substrates doped with Te up to 4 x 10(17) cm(-3) or Zn up to 1 x 10(19) cm(-3).

This result follows from the fact that a unitary impurity produces a marginally bound state at zero energy which decays as a power law along the nodes of the d-wave energy gap. Consequently, for finite density of impurities, the impurity-induced states are coupled by long-range overlaps yielding extended quasiparticle states below a characteristic energy scale omega(c). Simple scaling arguments suggest that omega(c) proportional to e(-c/nimp), with n(imp) the impurity density and c a positive constant. C1 LD LANDAU THEORET PHYS INST,MOSCOW,RUSSIA.

The Goldstone modes evolving from the magnetic satellites consist of transverse spin-wave modes and longitudinal phason modes, which are associated with the rotational and translational symmetries of the SDW state, respectively. The phason modes bend toward the zone boundary H between the satellites and produce the recently observed 60 meV peak in the longitudinal cross section at H. We also report a new class of collective excitation which is associated with oscillations of the SDW wave vector. C1 UNIV CALIF SAN DIEGO,DEPT PHYS,LA JOLLA,CA 92093.

The wavelength dependence of the anisotropy is closely correlated with that of the electron-spin polarization. Based on a theoretical analysis, we show that the QE anisotropy is caused by an in-plane strain anisotropy arising from anisotropic strain relaxation. The QE anisotropy calculated from the in-plane strain anisotropy measured with X-ray diffraction and the measured QE anisotropy are in good agreement.
