The purpose of the work was to conduct biotesting for the presence of antibiotics in several lakes of the Akmola region, located in the zone of possible ingress of antimicrobial drugs into them. The adopted research method was the modified disk diffusion method, employed to determine the microorganisms’ sensitivity to the used antibiotics. As a result of the study, sensitivity ...

The installation of piles at construction sites produces vibrations that may extend for hundreds of meters from the location of the pile. Depending on their proximity to this activity, these vibrations can induce damage to nearby structures. The results of a vibration monitoring study that was performed at a water treatment plant in the Republic of Kazakhstan are presented. ...

The work assessed the bioecological characteristics of the rare species Juniperus sabina in Kazakhstan. The significance of the research is that it provides knowledge about the morphological and adaptive characteristics of juniper. The purpose of the research is to study the morphoanatomical features of the vegetative organs of Cossack juniper in the Karaganda and Ulytau ...

Nitro-substituted neonicotinoid insecticides have been widely used until recently to control a range of important agricultural pests. Growing concerns about thiamethoxam’s toxicity to pollinators have led to its use being restricted or to it even being banned in some countries. Nevertheless, in Asia, Africa, Southeast Europe, and South America thiamethoxam is still used. ...

The paper presents the results of the study of the proposed type of variable profile piles. The proposed type of piles is reinforced concrete driven piles segmented in length. Each subsequent section has a ra-dial displacement along the axis of symmetry relative to the previous section. The positive effect of the performance of the proposed pile is to change the nature of the ...

Introduction. A thorough evaluation of the calculations used to determine the boundaries of urban planning projects enables a comprehensive understanding of the socio-economic, cultural, and labor connections between cities and settlements. The significance of developing agglomerations in resource-limited environments lies in their potential to achieve a synergistic effect, where ...

Euonymus koopmannii is a rare and protected species in Kazakhstan, valued for its ecological role in soil stabilization and its ornamental properties. This study presents the first use of micropropagation and phylogenetic analysis for the endemic plant E. koopmannii. Seedlings of E. koopmannii proved to be more effective than internodes as primary explants for plant micropropagation ...

Saiga antelope (Saiga tatarica) is a protected species in Kazakhstan. Little is known about the parasitofauna of these mammals. Therefore, the focus of this study was to evaluate the prevalence and species diversity of Eimeria spp. infection in the Volga-Ural Saiga antelope population. In June 2023, 104 Saiga antelope fecal samples collected from the district of Zhanibek, ...

Wild apples and their hybrids are valued as a source of genetic resistance to biotic and abiotic stress. Malus niedzwetzkyana is an endangered ornamental apple species endemic to Southeast Kazakhstan, the center of Malus domestication. To test the fire blight resistance of M. niedzwetzkyana, eight plant genotypes were inoculated with a local strain of Erwinia amylovora. The ...
