Upper and lower bounds for the pressure error in the rectilinear flow along a slot with a pressure gradient
(Steinkopff-Verlag; Dr. Dietrich Steinkopff Verlag ; Springer Science+Business Media, 1979-07)
The rectilinear flow of a second-order fluid is considered between two infinitely wide and long parallel plates. The bottom plate is at rest and has a longitudinal slot in the direction of the flow, while the top plate ...
Fluctuations of macrovariables in nonlinear systems: Langevin equation approach
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1977-01)
Fluctuations in nonlinear Markovian systems are studied by the Langevin equation method using system-size expansion. Langevin equations with different random sources are constructed for the description of fluctuations to ...
Electrical Conductivity and Hyperfine Interactions in MxFe3−xO4MxFe3−xO4, above and below TN
(The American Institute of Physics, 1973-01-01)
For T<TNT<TN the results of the present study of the 57Fe Mössbauer spectra of Zn‐ and Ni‐substituted Fe3O4Fe3O4 are in qualitative agreement with those of recent investigations, supporting a band model for the conduction ...
Random‐Coil Dimensions and Dipole Moments of p‐Chlorostyrene Chains
(The American Institute of Physics, 1972-01-01)
Mean‐square dimensions and dipole moments of p‐chlorostyrene chains CH3�[CH(p‐C6H4Cl)�CH2�]xHCH3�[CH(p‐C6H4Cl)�CH2�]xH have been calculated as a function of their stereochemical structure, degree of polymerization x, and ...
Model networks of end‐linked polydimethylsiloxane chains. II. Viscoelastic losses

Vibrational exciton cluster states, percolation and pairwise interactions: Benzene A2u band
(Elsevier, 1978-04-01)
Infrared spectra of isotopic mixed benzene crystals (C6H6/C6D6) were obtained at about boiling nitrogen temperature, with, emphasis on the umbrella mode (at about 700 cm-1). These are interpreted in terms of guest cluster ...
Structure of the Combinatorial Generalization of Hypergeometric Functions for SU(n) States
(The American Institute of Physics, 1971-03)
The combinatorics of the boson operator formalism in the construction of the SU(n) states provides a natural scheme for the appearance of certain generalized hypergeometric functions. It is shown that, while special cases ...
The electron-hole liquid in a polar semiconductor: Cubic SiC
(Elsevier, 1979-01)
The binding energy EB = (17 +/- 3) meV and density n = (9.2 +/- 1.7) x 1018 cm-3 of the EHL in cubic SiC are determined from excitation-dependent spectra. Comparing these values with ground state properties calculated ...
Neutron scattering study of the phase transitions in a doped polycrystalline Fe3O4: Zn0.005Fe2.995O4
(Elsevier, 1977-02)
Temperature dependent neutron elastic scattering and resistivity measurements have been made on a polycrystalline sample of Zn0.005Fe2.995O4, which displayed a well-separated, bifurcated, heat-capacity anomaly. The ...
Electron-positron annihilation: Statistical and thermodynamic considerations
(Elsevier, 1975-06-09)
Lightcone considerations suggest that, in e+e- annihilation, the hadronic matter is initially created within a spatial volume in the c.m. frame of the order of E-3, where E/2 is the colliding beam energy. Its implications, ...
