The aim of this study is analyzed nexus between energy intensity, CO2 emissions with food security in Kazakhstan. As dependent Food security indicator food production index and for energy intensity indicator Energy intensity level of primary energy were taken. As socio-economic indicators GDP per capita and population growth are taken. Data cover 2000-2021 years and extracted ...

The paper presents the results of a study of topological algorithms for the formation of a steady state of a complex electrical network, on the convergence of the iterative process. For a power transmission with distributed parameters, consisting of 5 nodes with a voltage of 500 kV, operating on a system of unlimited power, it is shown that there are two solutions and the ...

The article analyzes the state of the environment in the East Kazakhstan region. The authors, having analyzed official sources, showed that as a result of the restoration of production volumes at non-ferrous metallurgy and thermal power enterprises, there is an increase in emissions of hazardous waste by individual enterprises in this industry into the environment. In ...

The object of this study is the analysis of questionnaire data using ontological modeling. The task relates to the fact that conventional methods for processing questionnaire data are often insufficiently effective when working with large volumes of information and do not make it possible to automate many analysis processes. As a result of the study, an ontology ...

Water quality in rural areas of developing countries is a notable problem. In this article, drinking water quality from eleven villages in the Pavlodar and the Akmola region of Kazakhstan was analyzed. Questionnaires of village respondents and chemical components of drinking water were analyzed to identify the quality of drinking water. In each of the villages, the chemical ...

Geographical education in the post-Soviet countries after independence is oriented to the Western model of teaching disciplines. What positive and negative results have been obtained to date are discussed in this article. In the last four years, the educational process in schools has been focused on an updated program. As a result, an interesting question arises: how do we ...

The relevance of this study stems from the desire to develop efficient and sustainable methods of energy extraction from low-temperature geothermal resources, which is of key importance in the context of finding alternative energy sources and reducing dependence on conventional, often nonrenewable sources. The purpose of this study was to analyze the organic Rankine cycle ...

This paper presents the results of a study on radio-absorbing materials in the ultra-high frequency range of 78-118 GHz. Crystalline graphite powder (particle size 0.1 mm) was considered as the main radioabsorbing material. Epoxy resin was used as a substrate and a binder. The samples were prepared by dispersing the graphite powder across the surface of the epoxy resin ...

The article presents the nature of regional conflicts as one of the types of social conflicts in the context of traditional (naturalistic) and activity approaches. The authors reveal a number of conditions that determined the reasons for use of social conflicts in the second half of the 20th century, as well as the features of the increased demand for them in terms of solving ...

In the production of reinforcing ropes, the patenting of wire rods is carried out under the technical production regulations. Patenting is a consequence of isothermal treatment, in which the decomposition of supercooled austenite is carried out in the lower part of the temperature range of diffusion transformation. In the microstructure of patented steel, there should be ...
