The article considers the problem of studying and preventing, and also presents the results of the authors' practical experience - an express study to identify bullying in schools in Almaty. An analysis of the experience of foreign countries in preventing bullying shows that many of their programs are aimed at attracting all members of the teaching staff. The authors ...

The article presents the results of the functional zoning of the delta of transboundary river Syr Darya, which is located in an ecological disaster zone and is the only watercourse in modern conditions that supplies the remained part of Aral Sea. Under the conditions of global climate change, the territories of river deltas in arid regions are subject to active degradation ...

The article examines the key aspects of the environmental condition of the Pavlodar region in the 1990s. It provides an analysis of the climate, the structure of industrial production, and the availability of minerals. Based on statistical materials, the state of atmospheric air characterized by the presence of harmful impurities polluting the environment has been ...

The efficiency of a wastewater treatment process may be affected by several factors including the scale at which the system is operating. This study aimed at investigating the influence of scale on a poultry slaughterhouse wastewater treatment process. The process is comprised of several units including electrolysis, membrane filtration, and ultraviolet irradiation. The results ...

Kazakhstan has large reserves of natural resources, including coal, oil, and natural gas. We hope to replace fossil fuels with renewable sources of energy—particularly renewable natural gas. Thus, Kazakhstan, like other countries, should cut its dependency on coal, oil, and natural gas so as to reach net zero carbon emissions by 2050. This study, given that Kazakhstan is an ...

This work dedicated to the investigation cosmological models based on tachyon field. It was showed that Einstein’s field equations for spatially flat, homogeneous and isotropic Friedman-Robertson-Walker space-time have form-invariance of symmetry, obtained by form-invariance of transformations. The form-invariance of transformations is specified in the general case by the ...

We report the first results of a TEM study of structural changes induced by high energy xenon and bismuth ions in Y4Al2O9 nanoparticles (10 to 100 nm grain size) in the range of electronic stopping powers 6 ÷ 35 keV/nm. It was found that swift Xe an Bi ion irradiation, starting from threshold energy loss ~ 8 keV/nm, leads to the formation of continuous amorphous latent ...

Water absorption into cement mortar with different water to cement ratio was studied using neutron radiography in order to assess the durability and stability of these mortars. While the samples absorb water, neutron radiography images were acquired regularly as the absorption time elapses. The time evolution of water front position or penetration depth and the water content ...

This paper considers the effect of adding niobium oxide (Nb2O5 ) to ferroelectric ceramics based on calcium titanate (CaTiO3 ), and establishes a connection between the observed alterations in strength and dielectric properties and the variation in the Nb2O5 dopant concentration in the ceramics’ composition. The method of mechanochemical solid-phase synthesis was used as the ...
