Applied Sciences, Journal Year: 2023, Volume and Issue: 13(17), P. 9958 - 9958

Published: Sept. 3, 2023

Sunflower is a major agricultural oilseed crop, and the Republic of Kazakhstan has been steadily strengthening its position as producer oilseeds. In this study, an oil pressing machine with two processes, including grinding sunflower seeds obtained cake to separate oil, constructed. The experiment investigated impact different degrees (hole diameters plates 5 mm, 4 3 2 mm) screw rotation speeds (ranging from 30 rpm 250 rpm) on efficiency. study used content 45–47% moisture 7–9%. results showed that increasing degree speed led higher yield. optimal condition was mm 60 rpm, resulting in highest yield 15.6 g/s. Additionally, residual seed decreased significantly pressure increased during pressing, particularly grinding. Power consumption finer degrees, indicating influence components energy demand. density highlighting mechanisms compactness. Moreover, temperature rose presence sieves. These findings provide valuable insights into optimizing process, importance selecting appropriate maximize

Assessing Variability of Soil Quality in Western Kazakhstan: Dynamic Effects of Grazing Practices

International Journal of Design & Nature and Ecodynamics, Journal Year: 2024, Volume and Issue: 19(3), P. 875 - 885

Published: June 25, 2024

Preserving the quality of pastoral ecosystem soil is crucially important for production nutritionally complete feed livestock industry as part ensuring national food security.In Kazakhstan, such useful tools include assessment and evaluation dynamic changes in properties connection with agricultural grazing.The purpose study to assess current conditions pasture Western Kazakhstan using classical field research methods popular laboratory analysis.The conducted semi-desert zone based on Miras peasant farm demonstrates that rotational grazing more optimal maintaining preserving compared intensive without breaks.Results demonstrate maintains effectively than grazing.Specifically, under grazing, humus content significantly decreased by 0.47%, while showed minimal (decrease 0.09% 1 0.05% 2).Humus stock was also better preserved fields, only a 3.07-4.68%reduction, 27.05% decrease grazing.These findings suggest can mitigate degradation effects properties.The physical (density, structure) chemical (humus content, stock, mobile phosphorous, exchangeable sodium) were found be pastures where employed.The assessing taking measures prevent potential region.In addition, will land its economic use many countries similar management.

Abstract The article gives a geobotanical description and floristic analysis of communities with the participation rare relict species Alnus glutinosa in condition Aktobe region. aim study is to provide assessment current status rare, population, which was included Red Data Book Kazakhstan. At present, flora region not sufficiently studied. Conservation biodiversity one most topical issues. In region, due lack grazing, felling trees, using as fuel emergence uncontrolled tourism at same time natural renewal area, these consequences lead quantitative reduction species. this regard, it necessary organize protection conservation measures. results showed that plant rarely found Kazakhstan also distribution areas are reduced. Of three investigated points, plants from 24 families were identified. Plant being studied for first For conditions habitat black alder discovered. floral composition grown various ecological environments revealed, ratio life forms phytocenotic features time. addition, felt mite ground bug, damaging alder, identified 3 populations. It has been established main reason spread pest very strong moistening on sticky Alder grows. Results sequencing DNA sample under belongs fungus Alternaria alternata.

Influence of Natural, Climatic, and Industrial Factors on Air and Water Quality in The Kemerovo Region (Kuzbass, Russia)

Qubahan Academic Journal, Journal Year: 2023, Volume and Issue: 3(3), P. 1 - 10

Published: Sept. 28, 2023

Geographical and climatic features of the Kemerovo region (Kuzbass, Russia) determined modern geological geomorphological structure territory, as well a characteristic pattern in distribution mineral deposits. The purpose this work was to study hydrological region. Atmospheric circulation, relief, vegetation are climate's main factors. combination these factors forms characteristics Soils open areas (meadows, hayfields) occupy small area have high economic ecological value. Most forest is not affected by activities. exception disturbances territories logging mining enterprises, which especially affect air water quality All obtained results assessment condition should be used when planning further experiments on stages technical biological reclamation disturbed lands enterprises restore cover primary state soils.

Influence of Coal Mining Activities on Soil's Agrochemical and Biochemical Properties

Qubahan Academic Journal, Journal Year: 2023, Volume and Issue: 3(4), P. 387 - 399

Published: Dec. 1, 2023

Recultivation of technologically disturbed land is an important objective environmental protection. The study aimed to examine the impact coal mining process on agrochemical and biochemical parameters soil. Agrochemical analysis soil samples was conducted before after reclamation stage. baseline indicators mines indicated that all studied territories needed a full cycle recultivation measures. Before initial stage recultivation, content carbonate-ion, bicarbonate-ion, copper, lead, zinc, cadmium, petroleum products in from mine met norms requirements authorizing documents, part territory Sample 2 were marked by increased pH reduced humus content. All exceeded background values mobile forms manganese, nickel, chromium, cobalt. To effectively improve fertility, it recommended use biochar, compost, and/or peat apply organic inorganic fertilizers. next research will involve biological technogenically areas with cultivated wild plants.
