The durability of the targets and entrance window foils of the Dubna gas-filled recoil separator working at high intensive heavy ion beams was considered. The temperature, as a factor determining their durability, was calculated as a function of time in the conditions of their pulsed heating by heavy ion beam, followed by radiative cooling by radiation emitted from their ...

Самый распространенный тип рака в структуре онкологических заболеваний – рак легкого, который представляет собой серьезную проблему не только в Республике Казахстан, но и по всему миру. Воздействие радона классифицируется как вторая причина развития онкологии легкого. По оценкам экспертов, естественный радиационный фон составляет 80 % от среднегодовой дозы облучения населения ...

We study a class of shear-free, homogeneous but anisotropic cosmological models with imperfect matter sources in the context of f (R) gravity. We show that the anisotropic stresses are related to the electric part of the Weyl tensor in such a way that they balance each other. We also show that within the class of orthogonal f (R) models, small perturbations of shear are damped, ...

This article considers the gnoseological aspect of cross-cultural communication. The terms “linguistic consciousness" and “intension” are detailed in the article. Knowledge about education science and psychology of cross-cultural communication are considered, which assume learning of information about cross-cultural communication as psychocognitive and sociocultural pragmatic ...

The aim of the study is to investigate gender and absolute ‘I’ of a person as scope of contraposition and new contexts of identity. The methodological basis of the study of the philosophy of gender is the idea of the Absolute ‘I’ of a person, scope of contraposition of gender and sex, new contexts of gender identification. Person is inseparable from his essence, which ...

In modern construction, glued wood is used mainly by Scandinavian countries, Canada, the USA and Russia. It is rational to use glued wood not only in low-rise housing construction, but also as supporting and protecting structures of large-span public buildings. Large-span glued wooden structures have become popular in modern construction and are widely used for public ...

The purpose of the current study is to develop a reliable scale to be used to determine the scientific inquiry competency perception of post-graduate students engaged in post-graduate studies in the field of educational sciences and teacher education in Kazakhstan. The study employed the descriptive method. Within the context of the study, a scale was developed to determine ...

This article presents the preparation and study of the wetting properties of porous alumina membranes (PAMs) with a thickness of 25 to 75 μm and with a different pore sizes. The fabrication process features, scanning electron microscopy and atomic force microscopy characterization results are presented. The comparative analysis of PAM surfaces (outer and inner) and the effect ...

The need to improve the content of education disciplines at secondary and higher educational institutions and to create more favorable methodological conditions for curricula implementation in Kazakhstan have been gaining importance in recent years. Analyses of practical activity specified that the Kazakh, Russian and foreign languages in Kazakhstan should be primarily studied ...
