Analysis of the labor market and employment, unemployment of the population in Pavlodar region
Annotation:

Unemployment appears as a clearly negative phenomenon. It is unprofitable to all – both employers, and employees, and the state. Unemployment – is primarily a loss of income of a person, deprivation of the usual way of life. The urgency of this problem is due primarily to the fact that it is one of the important factors affecting economic and socio-political security. The vital interests of society, the state and the individual are closely intertwined in it. In our society, unemployment becomes a chronic disease, the state is not able to overcome it, and people demand respect for their rights to work, free choice of their activities and professions, improvement of living and working conditions, and social protection from unemployment. The article studied both the labor market in the Pavlodar region, as a whole and its individual segments in the context of the regions, its place in the market infrastructure, the main causes of unemployment, the qualitative composition of the unemployed

Extraction of non-ferrous metals from dusts of converter steel-melting production
Annotation:

In the article presents the results of studies on the effect of temperature and pressure on the chloride sublimation of zinc and lead from converter dusts of steel production. Currently, an objective necessity is the development of dust utilization technologies for converter steel production, with its further use in production and production of by-products. The use of dust allows not only to save natural raw materials, but also increases production efficiency and improves the environmental situation. The content of non-ferrous metals in dusts makes it difficult to process and use them in agglomeration or in blast furnace production, while the iron content in converter dusts (sludges) makes it possible to use them as promising metallurgical raw materials. Therefore, for a more complete processing of dusts, extraction of non-ferrous metals from them is proposed. The purpose of this work was to determine the possibility of extracting zinc and lead from sludges of the converter production by the method of chloride sublimation. We used dust containing: 86,3 % Fe2O3, 3,5 % FeO, 0,9 % Al2O3, 1,6 % CaO, 0,9 % MgO, 1,1 % MnO, 0,8 % SiO2, 4,4 % ZnO, 0,5 % PbO. The study was conducted in the temperature range 200-1600 degrees C and pressures of 0,01; 0,1 and 1 bar based on a complete thermodynamic analysis using the HSC – 5.1 software package. Finnish metallurgical company Outokumpu, based on the principle of minimum Gibbs energy. According to the results of the studies, it was found that, at normal pressure, lead chloride sublimationbegins at a temperature of 600 degrees С, and zinc - at 900 degrees С: a decrease in pressure to 0,01 bar reduces the temperature to 500 degrees С and 700 degrees С, respectively; lead chloride sublimation under equal conditions is more complete than zinc; To achieve zinc chloride distillation at the level of 90-96 %, the process must be carried out at 1145-1200 degrees С and pressure from logP = -2 to 1,2 bar, while the degree of lead chloride distillation is 99,8-100 %.

Influence of ultrasonic treatment on the efficiency of biogas production
Annotation:

This paper presents the results of the influence of ultrasonic treatment in the cofermentation of the cattle manure mixture (cattle) with the leaven from the rumen of ruminants on the process of biogas production. Anaerobic digestion was carried out in matinence periodic operation at the mesophilic temperature of 38 C ̊. As a substrate, a mixture with a content of 70 % cattle manure and 10 % leaven from rumen of ruminants was used. Treatment with ultrasound of the mixture was carried out at an intensity of 10 W/cm2 and an amount of input energy of 9350 kJ/kg of dry matter (DM), which completely eliminated the processes of stratification and sedimentation. Decomposition of organic matter (OM) in the periodic regime with the enzyme and ultrasound treatment occurred within 8 days, the usual substrate during this time OM decomposed 3.0 times less (only 14 %). The process of fermentation of methane in continuous and periodic modes treated with ultrasound, as at other temperatures, was stable, as can be judged by the values of volatile fatty acids (VFA) Volatile fatty acids (VFAs), alkalinity, pH, and biogas. The energetical efficiency of methane fermentation is estimated by comparing the volume of fuel (biogas) and heat consumption for technological needs. As shown by the comparison of efficiency of different regime, the largest amount of commercial energy in the form of biogas was obtained in the mode of joint fermentation of a mixture of cattle manure (cattle) with a ferment from the rumen of ruminants treated with ultrasound – 3 times more than without treatment (space).

Factors of economic space and business network in improving the economic security of business
Annotation:

In the conditions of modern economy, factors that affect the security of the business, but relate to external resources in relation to the company or opportunities, become significant. These resources and opportunities in economics have traditionally been identified with macro-economic (economic growth, inflation, exchange rates, government support) and institutional parameters (regulatory framework, transaction costs). The influence of the quality of economic space on economic security of business through the evaluation of opportunities that are tied to the specifics of the economic space is the least researched, including in our country. In this case, according to the latest research in the field of economic geography, economic space acts as a structure-forming platform that can form local markets, with intensive interaction of business agents. The purpose of this study is ensuring of economic security by building business networks in a single economic space. The research area focuses on indicators that characterize economic space, which are successfully used in international practice to determine the quality of economic space. The realization of this approach requires the use of traditional methods of scientific research, such as analysis, comparison, graphical method for visualizing obtained results, which allows determining the agglomeration zone and the space of business networks in it. When considering economic space in relation to building a business network in improving business security, main focus is on the quality of economic space that the region has. The proposed methods of evaluating the quality of economic space are actively used to determine the possibility of building business networks in this space. The authors conclude that business networks play a crucial role in improving the economic security of business in a particular economic space. The set of proposed measures provides additional opportunities and increases the influence of economic space on business security and creates the zone of maximum external security

Creating an intelligent management environment for a powerful load node on the example of the Pavlodar region
Annotation:

The present stage of development of power systems is characterized by the need to increase their intelligence, that is, the formation of an environment capable of solving the problems of effective management of all components included in the power system. One of the features of modern energy systems is an active consumer, that is, a consumer who has the opportunity to optimize the schedule of loading their capacities, planning energy consumption, intellectualization of energy consumption. In addition to the fact that there are digital systems for collecting, processing and presenting information, as well as transmitting this information via the Internet, to solve the most difficult task of managing power systems, it is necessary to develop a large number of models adequate to real processes that can describe the processes taking place in the power system under consideration. The purpose is to develop models capable of adequately describing the interrelated processes occurring in the considered elements of the power system, as well as in the aggregate of related elements; development of methods that allow solving problems of effective control of elements of energy systems on the basis of the proposed intelligent models. To solve the problem of increasing the intelligence of the power system, nonlinear adaptive models of electrical complexes of an energy-intensive enterprise included in the power system were developed on the basis of balance equations and artificial intelligence methods. The production of alumina with the properties of inertia, nonlinearity and closure is chosen as the production under consideration. This type of production was chosen as the most difficult to predict due to the unpredictability of changes in energy consumption during the transition to other modes of its operation, associated, for example, with the receipt of raw materials with a different chemical composition for processing. Static and dynamic models of energy consumption of electrotechnical complexes with continuous inertial nonlinear closed production based on artificial intelligence methods have been developed, which makes it possible to eliminate the need to use long time series of retrospective data. For the considered type of continuous energy-intensive production, dynamic characteristics of energy consumption and technological processes are obtained from the main controlled parameters, which make it possible to predict emergency situations and partly man-made disasters. On the basis of a genetic algorithm, a multiparametric optimization problem of energy management of continuous production has been solved, taking into account technological parameters and cost factors.
