Analyzing the impact of competitiveness factors on increasing grain production in Kazakhstan and Russia.

The main research objective of this study is to conduct a detailed econometric analysis of the factors affecting the competitiveness of cereal production in Northern Kazakhstan and the Volga region of Russia, focusing on climatic conditions, irrigation systems, and soil cultivation technologies. The assessment of grain production competitiveness was considered for the period 2018-2020 in the context of the following indicators: grain yield, grain sown area, and gross grain harvest. The data analysis also included indicators of annual domestic grain consumption and total grain production in Kazakhstan and Russia.

Density Functional Theory-Based Indicators to Estimate the Corrosion Potentials of Zinc Alloys in Chlorine-, Oxidizing-, and Sulfur-Harsh Environments.

Nowadays, biodegradable metals and alloys, as well as their corrosion behavior, are of particular interest. The corrosion process of metals and alloys under various harsh conditions can be studied via the investigation of corrosion atom adsorption on metal surfaces. This can be performed using density functional theory-based simulations.

The Effects of Heat Treatment on the Oxidation Resistance and Fatty Acid Composition of the Vegetable Oil Blend.

The purpose is to elucidate the effects of the duration of heat treatment on the resistance of vegetable oils to oxidative processes. Iodine and acid values were analyzed before and after heat exposure. Rapeseed oil, sunflower oil, and a blend of rapeseed and sunflower oils (ratio 55:45) were used as samples.

Study of vegetable oils and their blends using infrared reflectance spectroscopy and refractometry.

The present study aims to perform a comparative analysis of vegetable oils and their two-component blends using infrared spectroscopy and refractometry. The study was conducted in Almaty (Kazakhstan) in 2020. Three samples of 44 vegetable oils and their blends made from two components were examined.
