In the countries of the world, the preservation of environmental objects and atmospheric air is considered as an urgent problem. In this process, in large cities, a lot of attention is paid to the use of electric vehicles instead of cars with internal combustion engines. The article presents the possibilities for the development of electric vehicles in the Republic of Uzbekistan, the reforms carried out in this direction, and the current tasks for organizing the service. In particular, electric vehicle charging stations, the cost of an electric vehicle and a car equipped with an internal combustion engine of the appropriate class for a 100 km journey, as well as the work that needs to be performed in a scheduled service, are analyzed in detail.

The article presents information about high-temperature superconductors (UHO`O`) and their practical importance. Special attention is paid to YuHO`O`s made using solar energy. The reason for drawing attention to these YUHOs is the phase changes observed in them at high temperatures (even at room and higher temperatures). In addition, the technology of preparation of the critical temperature (Tc) of the transition to the state of superconductivity, changes under external influences, and structural changes are also of scientific and practical importance.

Different mathematical models often lead to differential equations of hyperbolic type. Such equations rarely have perfect analytical solutions. The most common are digital methods. They are widely used in solving quasi-linear gas dynamics equations (numerical methods of gas dynamics). This article deals with the comparison of different schemes for solving equations of hyperbolic type.

This article talks about economic equilibrium and its forms. Private equilibrium is the quantitative equalization of two interrelated economic indicators or aspects of the economy. Private balance is manifested in the form of a balance between production and consumption, purchasing power of the population and supply of goods, budget revenues and expenses, demand and supply for individual goods. means equal. General economic equilibrium is seen in market conditions, first of all, when aggregate demand and aggregate supply are equal.

The anatomical and physiological structure of the human body changes over time. In the elderly, it manifests itself in the destruction of bones, reducing the elasticity of muscles, covering them with fat layers. This condition manifests itself early in women and passes quickly. A group of scientists grouped the structure of the women's body, analyzing the location of fat deposits in the chest, abdomen and buttocks, the position of the head, the shape of the shoulders, how straight or bent the figure is.
