Improving the efficiency of the road transport power supply system
Annotation:

The article discusses a way to increase the efficiency of automobile operation by improving methods for ensuring the operability of electrical equipment based on the diagnosis of generators by output voltage. As a diagnosis, it is proposed to perform a spectral analysis of the generated voltage in idle mode and to determine the state of various generator elements from the results. The effectiveness of the proposed solutions is determined by the non-separable diagnostics of the generator, which, based on a thorough examination, can determine the state of various elements of the generator. This method does not require taking the generator out of operation, does not depend on its design and can be used in difficult operating conditions to obtain preliminary information about the state of the generator at the initial stage of maintenance.

Research of fungal diseases of herbaceous plants exposed from Aksu Ferroalloy Plant
Annotation:

Main problem: Technogenic "metamorphosis" of vegetation near such large industrial facilities as Pavlodar is considered to be the result of various active chemical and mechanical factors provoked by economic activities associated with the influence of emissions from industrial companies. The effect of anthropogenic impacts on vegetation in all regions of Kazakhstan varies and is largely dependent on the economic development of the territory, but in any case, the end result of this impact is the change in the vegetation, causing violations of with structure, reduced vodorazdelnaya flora and productivity of communities. This, in turn, can cause infection of herbaceous plants with pathogenic fungi, which then carry with them: a decrease in the intensity of plant growth, a deterioration in their decorative qualities, a decrease in the survival of the biological species. Purpose: to study the types of fungi-pathogens of phytopathogenic diseases and to determine the degree of modification of the plant component, which is under intense negative technogenic influence from the Aksu Ferroalloy Plant (AFР). Мethods: For the experimental study, species of plants such as: Artemisia dracunculus L; Artemesia vulgaris L; Atriplex fera L; Atriplex patula L; Artemisia annua L were selected for the content of fungipathogens of phytopathogenic diseases. Results and their significance: This experimental study was aimed at the presence of fungi-pathogens of herbaceous plants as a result of human impact, occurring near the industrial zone "AFР". The composition of fungi-pathogens of herbaceous plants collected in this industrial zone was considered and studied. According to the results of an experimental laboratory study, phytopathogenic fungi of herbaceous plants belonging to 1 ordo, 1 familia, and 4 species were found.

The possibility of using correlation and regression analysis in ecological and economic research at oil refineries
Annotation:

It is known that an increase in the volume of production in any sphere of production as a consequence increases the intensity of anthropogenic impact on the environment, including the atmosphere. This problem is especially typical for oil refineries. On the one hand, this is due to the complexity of oil refining processes and the release of various hydrocarbon compounds into the atmosphere during processing. Therefore, when implementing sustainable ecological and economic development in the Azerbaijani regions that are associated with oil refining, an increase in the volume of products should not create an increase in environmental impact. This problem is considered one of the factors directly affecting the economic situation of the enterprise, as well as creating certain environmental, social and economic problems for society as a whole. The purpose is to study the possibility of using the correlation-regression method in solving the problem of determining the presence of the decapling effect. The relationship between the volume of petroleum products produced and the amount of pollutants released into the atmosphere is random and is characterized by stochastic and statistical dependence. At the same time, on the basis of a mutual comparison of the methods of correlation and regression analysis and the method of production function, the effectiveness of correlation and regression analysis is determined. The methodological basis of the work was the scientific works of scientists-economists, mathematicians providing the definition of the decoupling effect at industrial enterprises. In the presented methodology, the obtained estimates of the performed in real time vary depending on the values of the set parameter. When developing the presented methodology, the STATISTIKA software package was used. This program was developed by StatSoft. Based on the obtained and experimentally verified data, the equation of linear regression dependence is determined. During the research, it was found that in some cases it is not possible to evaluate the statistical characteristics of a random variable or it is accompanied by serious errors. Therefore, when processing data, instead of mathematical expectations and variances, we used selective mathematical expectations and variances. The analysis of the ecological and economic situation of oil refineries based on correlation and regression analysis allows us to determine the presence of the decapling effect. The obtained correlation coefficient between the volume of production oil products and the volume of emissions into the atmosphere shows that there is no statistically significant relationship between these parameters. Thus, there is an achievement of the decoupling effect between the production of petroleum products and the volume of emissions of pollutants into the atmosphere.

Annotation:

Main problem: in Kazakhstan, the Government is reviewing its environmental and health management system to identify opportunities for improvement. Kazakhstan suffers from a high level of emissions into the environment and related health problems of the population. The link between environmental pollution and public health has been established for a long time. In Kazakhstan, air pollution, water pollution and soil and groundwater pollution are the main causes of widespread health problems and diseases, including, but not limited to, lung diseases and certain cancers. Recognizing these problems, the Kazakh Government is trying to strengthen environmental protection and environmental management system. Purpose: the purpose of the study was to analyze international models, practices, application of management systems for the legal protection of the environment and the health of citizens with application in Kazakhstan. Methods: the article discusses and explores a number of principles and methods of environmental management. Since these principles and practices contribute to the establishment of rational and effective environmental policy and management, it is proposed to take them into account when rethinking the current system in Kazakhstan. The article analyzes models and methods of legal protection of the environment and response to damage to the health of citizens, these tools can be part of an integrated system. Results and their significance: based on the study, it was found that in order for environmental management to reach its full potential, Kazakhstan also needs to undertake political reforms and involve ordinary citizens in the formation of policies and protection mechanisms. The studied strategies for collecting and taking into account the opinions of people when making managerial decisions on environmental protection can be used in Kazakhstani society.
