    Terbuthylazine and carbofuran effects on growth and reproduction within three generations of Eisenia andrei (Oligochaeta) (1994)

    Notes: Abstract Sublethal effects of terbuthylazine and carbofuran on the growth and reproduction of Eisenia andrei were investigated over a period of three generations. Reproduction was assessed by measuring the coccon production of worms treated chronically with pesticides. Inhibition of cocoon production was found in the parental generation. Hatchlings were raised from cocoons to provide the F1 generation. During raising a more rapid growth of juveniles treated with terbuthylazine was observed, compared with the growth of untreated worms. The increase in vitality was also found in cocoon production. Groups treated with terbuthylazine produced more cocoons than controls. The F2 generation was raised from hatchlings of the F1 generation, and here, also the terbuthylazine treatments increased earthworm growth, but not cocoon production. Exposure to carbofuran decreased cocoon production in all generations. Growth of the F1 generation was not influenced by low concentrations of carbofuran.

    In situ vibrational spectroscopy of specifically adsorbed azide on silver electrodes (1988)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 89 (1988), S. 583-589

    Topics: Physics , Chemistry and Pharmacology
    Notes: In situ infrared vibrational spectra of azide ions specifically adsorbed on polycrystalline silver electrodes immersed in aqueous electrolytes of composition 1 to 30 mM azide and 0.1 M perchlorate are reported for the potential range 0.25 to 0 V vs Ag/AgCl (3 M KCl). Adsorbed azide was not detected spectroscopically between 0 and −0.9 V, a range known from differential capacitance measurements to allow adsorption onto the silver electrodes. These experimental observations have been interpreted with the help of ab initio calculations of the vibrational frequencies of [AgN3]0 and [AgN3]− for two configurations with C∞v and C2v symmetries representing simple models for azide adsorbed with its configuration axis perpendicular and parallel to the electrode surface, respectively. Besides the charge states specified, calculations are also reported for static applied fields along the symmetry axis. Taken together, the experiments and calculations support a model in which azide adsorbs oriented perpendicular to the surface at the higher surface concentrations induced by potentials more positive than OV, and is adsorbed with long axis parallel to the surface at negative potentials.

    Sensitivity of elastic gas–surface scattering to the potential: A functional sensitivity approach based on wave packet dynamics (1990)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 92 (1990), S. 3170-3178

    Notes: Functional sensitivity analysis is used to study the effect of potential structure upon the elastic scattering of He atoms from a one-dimensional surface. The calculations are implemented by computing the total scattering wave functions from a wave packet calculation by a Møller wave operator method. The functional sensitivities of the various diffraction probabilities for several angles of incidence and surface corrugation are studied. The method is extended to examine the role of potential structure for a surface with adsorbed impurities. It was observed that the various diffraction processes draw from local regions of the potential in very different ways. At high angles of incidence for back scattering and particularly for strong surface corrugation, the large protruding portions of the surface cast a "shadow'' of lower dynamical sensitivity. Results of this type should ultimately be insightful for the inversion of experimental data to obtain the interaction potential.

    Distribution functions of a one-dimensional phase equilibrium with an interface (1987)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: We calculate the exact expression of the pair distribution function in the interface of the one-dimensional lattice gas, in which the separation of phases is achieved by imposing an external field which changes sign at the middle of the lattice. The exact distribution functions of arbitrary order can then be obtained from an earlier theorem of Percus. The pair distribution function is shown to decay exponentially as a function of interparticle distance, with a decay length equal to the correlation length of the spontaneous density fluctuations in either bulk liquid or gas phases. This exact result enables us to test approximate theories of the pair distribution function of nonuniform fluids. The exact expression of the direct correlation function is obtained from recent studies of Percus, and of Robert and Widom, and it also is used to test approximate theories of the direct correlation function of nonuniform fluids. Extremely severe disagreement is found between exact results and all commonly used approximations based on local thermodynamics à la van der Waals, while excellent, nearly perfect agreement is found for the dynamic capillary wave-like approximation of Kalos, Percus, and Rao.

    On the density expansion of the pair distribution function of nonuniform fluids (1988)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The density expansion method is used to determine the pair distribution function of a nonuniform fluid in one dimension in which a two-phase interface is induced by an external field. When the fluid is modeled by the lattice gas with nearest-neighbor forces and the external field by the step function that changes sign at the middle of the chain, terms of arbitrary order in the density expansion can be determined exactly. The kernels of the first- and second-order terms are evaluated in closed form and the pair distribution function is evaluated at each order. These results are tested against the exact expression of the pair distribution function of the same model interface, which was recently obtained by the transfer matrix method. It is found, especially for strong intermolecular forces, that the first- and second-order approximations are not only unable to improve the severe disagreement between the zeroth-order approximation and the exact result, but further aggravate this disagreement, suggesting that the density expansion of the pair distribution function is at best asymptotically convergent.

    Notes: Molecular beam electric resonance spectroscopy has been used to determine the radiofrequency and microwave spectrum of H2S⋅Ar, HDS⋅Ar, and D2S⋅Ar. The electric dipole moment and nuclear hyperfine interactions reflect an angular structure in which the H2S C2 axis is nearly perpendicular to the Ar...S axis, and the H2S and argon are nearly coplanar. The effective argon–H2S center-of-mass distance is 3.977 A(ring).
