The kinetics of hydrogen generation by heterogeneous hydroreactive compositions with aluminum, which was preliminarily γ-irradiated in air, held in aqueous solutions at room temperature, and annealed at a high temperature, was studied. Changes in the hydrogen generation kinetics depending on the γ-radiation dose, the composition of aqueous solution, and the temperature are caused by the conversion of aluminum oxide coatings, which should be taken into account in the prediction of the corrosion resistance of structural materials under the conditions of exposures at nuclear power plants. © 2017, Pleiades Publishing, Ltd.

This article presents a postnonclassical approach to create the science of management processes organization in a developing society, the focus of which is "the man of culture", i.e. the man, not just adhering to cultural norms, but also creating new concepts and products of culture. This science is proposed to be called Evergetics. The purpose of the study is the analysis science of management processes organization in a developing aerospace engineering and other industrial areas of society. The authors describe the main aspects and procedures evergetics management in aerospace engineering. They uses the comparison method, compares classical and modern approaches and technologies of management. In evergetics management model each member of society or organization is interested in augmenting his cultural heritage he is producing, which entails a raise of stability in process of engineering actions and a raise cultural potential of the society as a whole and, as a consequence, an increase in the proportion of moral and ethical managerial decisions and corresponding to them benevolent actions in organizational life. Summarize the article's main findings, authors may in some main conclusions about necessity evergetics model and intersubjective technologies in the creation and development of aerospace engineering. © The Authors, published by EDP Sciences, 2017.

The corrosion of chromium-nickel steel 08Kh18N10T in 2 M H2SO4 has been studied in a broad temperature range, t = 0-200°C. Under these conditions, the metal corrosion is enhanced with an increase in t to reach 9.7 kg/(m2·h) at 200°C. It has been shown that a formulation of IFKhAN-92 inhibitor (a substituted triazole) with KI in a molar ratio of 1:1 protects this steel in 2 M H2SO4 at temperatures up to 140°C, inclusive. The three-component mixture of IFKhAN-92, KI and urotropine (1:1:4) is more promising in this respect, as it efficiently inhibits corrosion at temperatures up to 180°C and allows the protective effect to be maintained for at least 8 h. This formulation also reliably protects low-carbon steel 20 in 2 M H2SO4 at temperatures up to 180°C, inclusive; what is more, corrosion slows down with time in the presence of this mixture. © 2017, Russian Association of Corrosion Engineers.

Taxonomy and geographical distribution of diatom taxa from the genus Eunotia are discussed. Fourteen Eunotia species are found in aquatic ecosystems of Central and South-Eastern Vietnam: E. indosinica, E. karveerensis, E. sulcata, E. cf. vumbae, E. novaecaledonica, E. naegelii, E. paramuscicola, E. rabenhorstii, E. tropica, E. sioliopsis, E. australominor, E. mucophila. Two species which are new for science are described Eunotia skvortzovii Glushchenko & Kulikovskiy sp. nov. and Eunotia fogedii Glushchenko & Kulikovskiy sp. nov. Eunotia sulcata Hustedt ex Glushchenko & Kulikovskiy is validated. The species are illustrated by original LM and SEM microphotographs. The main qualitative and quantitative taxonomic data are given. The distribution is found species is discussed. © 2017, Pleiades Publishing, Ltd.

The solutions analytically derived by W. Glöckle, J. Golak, R. Skibiński, and H. Witala [Phys. Rev. C 79, 044003 (2009)] for the three-dimensional wave function and on-shell t matrix in the case of scattering on a sharply cut-off Coulomb potential appear to be fallacious if finite values of a cut-off radius are concerned. And the analysis carried out for an infinite cut-off radius limit is incomplete. © 2010 The American Physical Society.

Based largely on homoplastic characters of external morphology, the current systematics of the tribe Onthophagini and allied dung beetle lineages is unstable, contradictory, and thus inefficient. A number of recently proposed molecular phylogenies conflict strongly with each other and with formal classification, and none of them provides new tools for the improvement of dung beetle systematics. We explored the source of these inconsistencies by performing an independent, morphology-based phylogenetic analysis of the "Serrophorus complex", one of the most systematically confusing knots among the onthophagines, that involves 52 species from various genera of Onthophagini and allied tribes. The phylogenetic pattern revealed conflicts with existing classifications and with most of the earlier molecular phylogenies. However, it was largely congruent with the molecular phylogeny (Evolution 2005, 59, 1060), using the largest gene sampling thus far. All current competing phylogenetic hypotheses were evaluated against each other, and the degree of their biogeographic plausibility was used as an additional evaluative criterion. Of the 91 morphological characters involved in our analyses, traits belonging to the endophallic sclerites of the aedeagus had a very strong phylogenetic signal. Terminology of these endophallic characters was established and their morphology was studied in detail, illustrated, and presented as a tool for further practical use. The enormous variety of shapes of the lamella copulatrix within the Onthophagini and allies present a methodological problem in character coding for phylogenetic analyses. Based on the performance of alternative coding approaches, it is argued that a seemingly less informative absence/presence coding scheme would be a better choice. The phylogenetic structure of the Serrophorus complex has been largely resolved, and some taxonomic changes improving its systematics are recommended. © The Willi Hennig Society 2011.

The results from using a new distribution function for the depth of characteristic X-ray radiation to calculate the allowance for absorption f(x) in quantitative electron-probe microanalysis are pre- sented. The integral (z) over z in the region of generation is proportional to the normalized absorbed energy value of the electron beam in a sample. This is used to calculate the backscattering factor R. © Allerton Press, Inc., 2012.

This article considers the peculiarities of cognitive functions in elderly mentally ill people and types of aging. Relationships between cognitive and personal functions, features of world outlook, and the quality of life in elderly people are analyzed. The paper provides data on features of cognitive processes in elderly patients of a psychiatric clinic, as well as of data on features of cognitive processes and personality in contemporary elderly persons in general. Characteristics (resources) supporting and inhibiting development in old age are discussed. © 2015, Pleiades Publishing, Ltd.

Examination of the type material of the Oriental representatives of the genus Onthophagus Latreille, 1802 (Coleoptera: Scarabaeidae: Scarabaeinae: Onthophagini) deposited at the Natural History Museum in London, National Museum of Natural History in Paris, Museum of Natural History in Basel and National Museum in Prague revealed seven new synonyms. The names synonymized herein were described as separate species mainly for two reasons. The first reason owes to the insufficient knowledge of entire Onthophagus diversity from Oriental Region and the fact that authors describing new species did not check the type material or even original descriptions for already described taxa. The following synonymized species were likely described due to this oversight: O. anamalaiensis Balthasar, 1974; O. chulapornus Masumoto, Ochi & Hanboonong, 2008; O. demaak Masumoto, 1989; O. jucundus Arrow, 1931; O. laosensis Frey, 1971; and O. parvidens Frey, 1971. The second reason is the great range of intraspecific variation of such allometric characters as shape of head, horns and pronotum in Onthophagus. Therefore, detailed examination of the external characters for the large series of specimens, and careful study of male genitalia are required for reliable species identification. Unfortunately, this was not the case for many new species descriptions. In particular, O. perroti Paulian, 1978, was described as a species but actually only represents the minor form of O. orientalis Harold, 1868. The lectotype of O. gracilipes is designated in order to preserve the stability of zoological nomenclature. Copyright © 2010.
