This article presents the results of a study on the influence of one component of a newly developed modifying additive (specifically, granite dust) on the strength properties of concrete. The comprehensive study included standardized tests of beam samples for flexural and compressive strength. The research was conducted with varying concentrations of granite in the ...

A simulation of the Stirling engine was carried out, where the temperature variability in the cooler and heater is taken into account, and the engine itself generates electric current. The study was carried out in the temperature range when the piston and displacer move synchronously. The possibility of increasing engine power by reducing hydraulic resistance in the regenerator ...

The following paper explores an impact green economic growth, renewable energy consumption, and industrialization have on food security in Central Asian countries, namely Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. We used a POLS model to analyze relationships between selected factors and food security based on panel data for the period between 2001 and ...

In the work on the example of barium magnesium fluoride activated by tungsten system the existence of possibility of introduction of activators, modifiers into the formed ceramics are shown. Using unique properties of radiation synthesis of high synthesis rate is happened. The possibility of synthesis of magnesium fluoride activated by tungsten, barium fluoride activated ...

The present study developed a novel approach for transforming red mud (RM) into soft magnetic materials (SMMs) for applications in advanced electrical devices in the form of Fe-Si and Fe-Si-Al alloys. A total of ten blends were prepared based on two RMs, three iron oxide additives (Fe2O3, black and red mill scales), alumina and carbonaceous reductants in a range of proportions. ...

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 ...

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 ...

Актуальность исследования обусловлена необходимостью очистки водных ресурсов от катионов Me(II). Получение действенных и дешевых сорбентов, позволяющих обнаруживать и адсорбировать катионы тяжелых металлов в питьевой или водопроводной воде и параллельно осуществлять систематический мониторинг качества воды в окружающей среде, является одним из приоритетных направлений для очистки ...

Current models for evaluating sustainable transport corridors often lack a comprehensive framework capturing the multifaceted performance measures vital for holistic assessment especially at the early stages of operation, when detailed information on the performance indicators of these transport corridors is not available. This gap motivates a Petri net-based modeling approach ...

This study aimed to elucidate the formation mechanisms of micro-macrostructural heterogeneities in the ingot's cortical zone and their transformation into surface defects during heating, plastic deformation, and rolling processes. The methodology and results of studying the macro- and microstructural and chemical heterogeneities of ingots and finished rolled sheets are ...
