TL;DR: In this paper, the composition, structure, and morphology of the films have been studied and data of X-ray diffraction and Xray photoelectron spectroscopy showed that copper in the solid solution occurs in a single-valence state (Cu+).
Abstract: Films of substitutional solid solutions of the Cu2Se-In2Se3 system containing up to 7.5 at. % In have been obtained by chemical deposition from aqueous media. The composition, structure, and morphology of the films have been studied. Data of X-ray diffraction and X-ray photoelectron spectroscopy showed that copper in the solid solution occurs in a single-valence state (Cu+). The deposited layers possess a globular morphology and are nanostructured.

TL;DR: The diagnostic sensitivity of non-invasive immunocytochemical Helicobacter pylori test in rectal smears was 90%, specificity 76%, and efficiency of the test 84%.
Abstract: We present the results of bacterioscopic and immunocytochemical study of Helicobacter pylori in biopsy specimens from the gastric antrum and smears from the rectum Predominance of spiral-shaped vegetative form of Helicobacter pylori in the antrum and the presence of cocci with Helicobacter pylori antigens in smears from the rectum were demonstrated in patients infected with Helicobacter pylori The diagnostic sensitivity of non-invasive immunocytochemical Helicobacter pylori test in rectal smears was 90%, specificity 76%, and efficiency of the test 84%

TL;DR: In this article, the process of temperature field formation in a layer of a weakly conducting medium with the example of wood and green moss under irradiation of one side with an energy flux and contact heat removal through the opposite back surface of the material onto an asbestos-cement support was investigated.
Abstract: We have investigated the process of temperature field formation in a layer of a weakly conducting medium with the example of wood and green moss under irradiation of one side with an energy flux and contact heat removal through the opposite back surface of the material onto an asbestos-cement support. The experimental results were compared with the data calculated on the basis of the relations of nonstationary heat transfer in the approximations of closeness and openness of the system. The conditions for heat removal suppression have been concretized and the role of the energy exchange under the prolonged action of radiant energy for estimating the thermal stability parameters of related materials has been elucidated. The obtained data can be used to control radiant fluxes in treating wood, for effective heating of living and industrial premises, improving the methods for opposing high energy fluxes, and preventing the propagation of fire in inhabited localities and in park and forest zones.
