    CYCLIC CRACK RESISTANCE OF WELDED JOINTS WITH NON-UNIFORM FIELDS OF RESIDUAL WELDING STRESSES (1996)

    Notes: Abstract— The use of linear elastic fracture mechanics to describe the kinetics of fatigue fracture of welded joints with high welding residual stresses (WRS) is experimentally evaluated in this paper. A correction analysis is used to show that the crack propagation rate of cracks in joints, as a function of the applied stress intensity factor, is linear on a log-log scale in the Paris regime when non-uniform fields of WRS are superimposed on the applied cyclic loading. It is shown that crack growth rates in joints with high WRS do not depend on the characteristics of the loading cycle. The parameters of the Paris exponential equation are determined by the initial WRS distribution, by the range of cyclic stresses and by the load ratio. A method for calculating the cyclic crack resistance of joints is proposed which explicitly allows for a non-uniform field of WRS that influences the fatigue crack growth rate.

    Notes: Lactate dehydrogenase (LDH) was adsorbed on low-(γ, η) and high -(θ, α) temperature forms of alumina. θ-Al2O3 exhibited the greatest adsorption ability. The maximum adsorption value was 30 mg LDH/g of a carrier. The conditions for irreversible adsorption have been determined. An adsorption isotherm on θ-Al2O3 for pH 6.0 has been obtained; the LDHads surface area and the carrier surface portion accessible to the enzyme molecules have been calculated. The reaction kinetic parameter were determined by taking into account the reaction proceeding in the intradiffusional region. The specific catalytic activity (Aspec) of LDHads at small surface coverage of θ-Al2O3 is five times less than Aspec of the native enzyme and KMimm with respect to NADH exceeds KMnat by two orders or magnitude. The is evidence for a strong LDH-Al2O3 interaction and a considerable deformation of the enzyme globule. Aspec and KM decrease as the amount of the enzyme attached to the carrier increases. Due to adsorption. LDH becomes thermostable and durable. The LDHads samples conserve 20-40% of their activity at room temperature during a year.

    Notes: Immobilization of gas-utilizing microorganism strains (Mycobacteria, Rhodococcus, methane-utilizers) on inorganic supports based on alumina, silicates, and carbon was carried out to develop heterogeneous biocatalysts for the biotechnologic processes, including the process of propene epoxidation. Adsorption ability of these microorganisms, biocatalytic properties of resting and immobilized bacterial cells, and effect of immobilization tehniques on biocatalysis were studied. An approach of double immobilization using inorganic materials (supports and gel) was proposed as simple, universal, and available methopd to immobilize bacterial cells, resulting in a higher retention (up to 100%) of cells' enzymatic activity and enhanced stability.

    Description / Table of Contents: Physical-chemical investigations into the protective layers formed on steel in sodium nitrite solutionsUsing a spectral analysis, metallography, X-ray spectral microanalysis and cross-section analysis the layer formed on the surface of carbon steel in aqueous sodium nitrite solutions has been studied. It has been found that the layer formed under these conditions on the steel surface is not a passive layer but a protective layer containing complex compounds of the type Fe(NH3)x(NO3)3 · yH2O. The thickness of the layer is 8 to 18 μm depending on the nitrite concentration in the neighbourhood.

Es wurde festgestellt, daß sich unter diesen Bedingungen auf der Stahloberfläche keine passive Schicht, sondern eine Schutzschicht bildet, welche komplizierte Komplexverbindungen des Typs Fe(NH3)x(NO3)3 · yH2O enthält. Die Stärke der Schicht beträgt 8-18 μm in Abhängigkeit der Nitritkonzentration in der Umgebung.

    Extended states of a shallow donor located near a semiconductor-insulator interface (1998)

    Notes: Scattering of a conduction electron by a charged shallow donor located near a semiconductor-insulator interface in the semiconductor or by a charged center embedded in the insulator is considered within the model of a hydrogenlike atom in a semi-infinite space. The interface influence is allowed for by spatial confinement of the electron envelope wave function. The impurity electrostatic image at the interface is taken into account. The problem is separable in prolate spheroidal coordinates and thus is solvable exactly. A rapidly convergent expansion is proposed for the angular eigenfunctions. The radial eigenfunctions are calculated directly by numerical integration of the radial boundary value problem. Expansions of the scattering wave function and the scattering amplitude in terms of the eigenfunctions of the problem are obtained. Using the extended and localized state wave functions, the photoionization cross section of a shallow donor near a semiconductor-insulator interface is calculated. It is presented as a superposition of the oscillator strengths of transitions to the partial extended eigenstates that constitute the scattering wave function. Near the interface, the cross section is enhanced significantly and redistributed over the direction of photoionized electron escape. The photoionization threshold follows the localized state energy varying with the donor-interface distance.   © 1998 John Wiley & Sons, Inc. Int J Quant Chem 66: 435-456, 1998

    On the quantum properties of adsorbed particles within the model of a hydrogen atom near a hard wall (1992)

    Notes: A hydrogen molecule near a hard wall was considered within the Heiteler-London method using the atomic orbits in the presence of the wall. Rapidly converging expansions of the atomic wave functions were proposed. The asymptotics were obtained and studied. The atomic dipole moment induced by the surface gave rise to a long-range interatomic interaction. The covalent bond length increased near the wall. Depending on the orientation relative to the wall, the potential well can vanish. It is interpreted as an interaction between the atomic dipole moments. An approximation of the interatomic potential was proposed.
