Analysis of the operation of exothermic-endothermic generators

Conclusions To ensure high-quality chemicothermal treatment of parts and to increase the service life of generators we recommend continuous furnaces with an independent supply of controlled atmosphere, a constant technological process, weekly burnout of the endothermic gas generator and furnace, and maintenance of constant pressure and temperature of the cooling water.Volga Automobile Factory.

Transformation of Magnetic State under the Influence of Superconductivity in Epitaxial V/Pd1−x Fe x Bilayers

We have performed ferromagnetic resonance (FMR) studies of epitaxial V/Pd_1−x Fe _x (001) bilayers with a V thickness of the order of 40 nm and with a Pd_1−x Fe _x thickness in the range from 0.8 to 4.4 nm. For a bilayer with a Pd_1−x Fe _x thickness of 1.2 nm and x = 0.03, the FMR measurements revealed a decrease in the effective magnetization 4πM _eff of the ferromagnetic layer below the superconducting transition temperature of vanadium. As a possible explanation for this decrease, we suggest a spatial modulation of the ferromagnetic order in the Pd_1−x Fe _x layer due to modifications of the indirect exchange interaction of magnetic ions via conduction electrons in the superconducting state. A comparison with a recent theoretical investigation supports this possibility.     

Luminescence and energy transfer in uranium-containing aqueous solutions of dysprosium decatungstate

Samples of uranium-containing liquid luminophores activated with Dy³⁺ were prepared, and their properties were studied experimentally. Optical excitation of aqueous DyW₁₀O₃₆^9– solutions leads to the transfer of the excitation energy from the decatungstate ligand to Dy³⁺, followed by sensitized luminescence of Dy³⁺.     

A Charged-Particle Detector Based on Proportional Tubes with a Segmented Cathode and Cathode Readout

A charged-particle detector based on proportional tubes with cathode readout is described. The cathode is sectionalized into 2.2 × 2.2-cm pads. The detector was tested on high-energy particle beams. At an anode-to-cathode distance of 1.1 cm, the spatial resolution was 1.25 mm along the anode wire. A simulation model of the detector on the basis of the measured pad-response function was proposed, compared to the experimental data, and used to calculate the two-track resolution. The detector can be used in various experiments as a large-area multiparticle two-coordinate detector.     

Analysis of the human immune response to vaccinia by use of a novel protein microarray suggests that antibodies recognize less than 10% of the total viral proteome

Control of smallpox by mass vaccination was one of the most effective public health measures ever employed for eradicating a devastating infectious disease. However, new methods are needed for monitoring smallpox immunity within current vulnerable populations, and for the development of replacement vaccines for use by immunocompromized or low-responding individuals. As a measure for achieving this goal, we developed a protein microarray of the vaccinia virus proteome by using high-throughput baculovirus expression and purification of individual elements. The array was validated with therapeutic-grade, human hyperimmune sera, and these data were compared to results obtained from individuals vaccinated against smallpox using Dryvax. A high level of reproducibility with a very low background were apparent in repetitive assays that confirmed previously reported antigens and identified new proteins that may be important for neutralizing viral infection. Our results suggest that proteins recognized by antibodies from all vaccinees constituted <10% of the total vaccinia proteome.     

Physicochemical properties of nanocrystalline composites based on ZrO<Subscript>2</Subscript>, Al<Subscript>2</Subscript>O<Subscript>3</Subscript>, and rare-earth oxides

Powder precursors have been prepared by means of the sol-gel technique and codeposition, and nanoceramics in the ZrO₂-Al₂O₃-rare-earth (RE) oxide system (RE = Ce, Sc, or Y) based on them have been obtained. Physicochemical properties of the resulting ceramic composites have been investigated. The energy model for oxygen-ionic transport processes in a solid solution based on ZrO₂, which relies on computer simulation procedure, has been proposed, and the structural, strength, and electrophysical characteristics of the solid solution have been calculated. The obtained materials are promising as high-melting electrochemical sensors in molten oxides.     

Complete metric on mixing actions of general groups

In this paper the metric on the set of mixing actions of a countable infinite group is introduced so that the corresponding space is complete and separable.
