Opis:: In this study, the methodological foundations of the technology for the local reduction of chemical pollution from vehicles were improved through the use of twolevel suction units and guide plates of various lengths installed on the nozzles of the suction devices. A program has been developed for the numerical calculation of the carbon monoxide concentration field for evaluating the efficiency of using two-level exhaust systems with different lengths of guide plates on the gas flow selection pipes. The solution of the equations of hydrodynamics and mass transfer is carried out on the basis of finite-difference methods. A number of physical and computational experiments have been carried out; it has been established that the concentration of carbon monoxide in the zone of two-level suctions location decreases by 46-68%.

Opis:: In this study, a mathematical method is proposed for calculating the concentration field of air ions of different polarities and dust levels in the passenger compartment, taking into account the geometry of the passenger compartment and seats, shelves, and other internal elements of the passenger compartment. The method also takes into account changes in the rate of the air flow ventilation, the location and number of ionizers, and sources of positive ions and dust, taking into account their different intensities and locations. On the basis of a numerical model for this method, software has been developed that allows users to carry out computational experiments without requiring much time for calculation. Based on the results, the optimal location of the ionizer in the passenger compartment of the car was determined to ensure comfortable conditions for the stay of passengers, which favorably affects their health. It has been found that the presence of two ionizers is optimal for creating comfort in the car with an ionization intensity of Qn= 0.47 ×1010 ions/s located at the top of the car. If there is one ionizer located on the dashboard or at the top of the car with a higher ionization rate than ions/s, it is not possible to simultaneously provide optimal ionization parameters for passengers in the front and rear seats of the car.

Opis:: This article assesses the impact of the development of logistics systems (LS) on the efficiency of the economy. A multi-level methodology for assessing the impact of LS on the economy consisting of six stages (transport, investment, economic, information, material and technical, labor and infrastructure) is proposed using a dynamic structural model for a group of macroeconomic logistical factors for the period 2009-2020 for the republic and the regions of Kazakhstan. Their close relationship with economic growth has been established. Based on the results of factorial and index methods of analysis, mechanisms of differentiation in the management of the regional economy are proposed based on the level of development of logistics and their impact on the growth of the regional economy. Four groups of regions are identified according to the level of development of logistics and their impact on the economy, and directions for their further development are proposed. The forecast is based on the studied factors up to 2030. In particular, it has been established that for the long-term development of the economy of Kazakhstan, the development of agriculture and industry, investment in fixed assets, freight turnover, the availability of vehicles, wages, communication services, and the density of the railway network are important factors.

Opis:: In this study, a numerical model is proposed for calculating pollution zones near the road, taking into account the geometry of the automobile transport meteorological conditions, the location of the barriers and their height, and the chemical transformation of nitrogen oxides in the atmospheric air. The numerical solution is based on the integration of the mass transfer equations using the finite-difference method. To determine the components of the air flow velocity vector, a two-dimensional model of the potential flow is used, where the Laplace equation for the velocity potential is the modeling equation. Based on this numerical model, a software package has been developed that allows computational experiments and does not require large expenditures of computer time. Based on the results obtained, an assessment was made of the effectiveness of the use of barriers to reduce the level of air pollution near highways. It has been established that the use of barriers of different heights reduces the level of pollution behind the road by approximately 20-50%.
