The pervasive presence and detrimental impact of microplastics in the environment pose a multifaceted and urgent challenge requiring innovative solutions and comprehensive mitigation strategies. This study investigated the efficacy of biofilm-enhanced coconut coir in removing microplastics from wastewater, addressing the pressing issue of microplastic pollution. Through ...

Understanding the effects of various superplasticizer (SP) types on the rheological characteristics of foamed cement pastes, as well as on the physical and mechanical characteristics of environmentally friendly porous lightweight aggregate concretes, is crucial. Differently extending the setting time of Portland cement (PC) pastes are three tested superplasticizers, ...

Pharmaceuticals are crucial for human health, but their release into the environment through various means can contaminate groundwater, surface waters, soil, and microorganisms. The contamination of water by pharmaceuticals in Kazakhstan is not well-studied. Understanding the influence of pharmaceutical ingredients on the ecosystem and public health is a key area of ...

Objective: The aim of this research is to analyze the feasibility and impact of the Tri N-based E-PBL STEM learning model on students' critical thinking skills and verbal representation in science learning. Theoretical framework: The competencies students must have in the 4.0 era are not just hard skills but more soft skills such as critical thinking and verbal representation. ...

The purpose of the study was to analyze the state of natural resources in the West Kazakhstan region during the 1990s to the early 2000s. The ecological condition of the region’s natural resources remains one of its most pressing issues, necessitating regular monitoring. Analysis of official data sources revealed that the socio-economic development of the region coincided ...

The global diversity of approximately 25,000 lichen species (e.g., from the genera Usnea, Cladonia, and Peltigera), including rare and endangered ones, highlights the importance of preserving their population in the State National Nature Park “Burabay”. The objective of this study was to investigate the distribution of rare lichen species in the territory of the State National ...

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 ...

It is shown that the predicted energy crisis in Kazakhstan makes the issue of small-scale energy and complementary civil society institutions more than relevant. This crisis, caused by the deterioration of heating networks built during the former USSR, can be more than large-scale, as evidenced by the events in the city of Ekibastuz, where a significant proportion of the ...

This paper investigates the effect of two-step sintering on the mechanical properties and microstructure of Sm2Zr2O7 ceramics obtained from submicron powders after high-energy milling. Two key parameters of the twostep sintering process are analyzed: temperature and duration, as both can significantly influence grain growth processes in ceramics. It was found that extending ...

Ferrimagnetic nanoparticles, which are compounds of iron oxide with other types of metal oxides, are one of the promising types of nanoparticles among a wide variety. Interest in this type of nanostructures is primarily due to the great prospects for their use in biomedical applications, targeted drug delivery, alongside hyperthermia and magnetic resonance therapy. The ...
