Annotation The properties of the atomic nucleus were studied, in particular the weight of quarks and the energy of gluons were calculated. The nuclear potential and quark mass were calculated from the kinetic energy and momentum. This is determined using integers on which the mass of quarks and the energy of gluons depend. The mass of quarks is approximately known, and a dependence on integer numbers of the quark mass is selected that is close to the experimental value. This allows us to more accurately determine the mass of quarks that satisfy the kinetic energy of the quarks and their momentum. The energy of the atomic nucleus and the energy of the atom are determined using STR formulas at imaginary speed.

This article brings together previously published evidence of the unified nature of physical processes and phenomena in terms of changes in the energy of a substance molecule. The unified physical nature of all these physical phenomena has been proven, as a single multistage process of energetic unpacking of molecules of a substance, which is logical to call the molecular-energy concept of unpacking a substance. The considered processes include the following processes. Surface rupture, characterized by the surface tension coefficient. The melting process of a substance characterized by its melting point. A boiling process characterized by the boiling point. Evaporation (and condensation) process characterized by internal energy and enthalpy as well as critical point. The conclusions of the theory are confirmed by well-known empirical dependences and by reference books of the physical properties of simple substances: internal energy, enthalpy, surface tension, melting point, boiling point and critical point.

The paper provides solutions for energy supply to agricultural consumers remote from energy sources due to non-traditional types of energy, based on patents of the Russian Federation. A scheme of a thermodynamic installation operating according to the Rankine cycle on a low boiling liquid is considered. The circuit uses a capacitor that increases the temperature of the condensate, leading to an increase in the efficiency of the thermodynamic installation. A series of graphs is given, confirming the required amount of heat received for the operation of the installation and a graph of the dependence of the efficiency of the installation on temperature conditions. A graph of solar energy is shown, which feeds per unit of horizontal surface and its integral value for one day. Options for improving the installation using concentrating receivers of solar energy are given. Test schedules for the solar collector module are provided.

In the article, the authors’ concept is presented, according to which all planets rotate about their axis due to their satellites. The planet and its satellite are interconnected by a shared gravity, which moves along the surface of the planet as the result of the satellite moving in an orbit. The discussed movement of gravity applies to all planets and the Sun. The shared gravity is at its maximum on the Earth and Sun surface. Particular celestial bodies have their beginning, evolution and end. On the whole, the Universe has always existed and will always exist, and such major formations as galaxies and stars will never cease to exist.

Trends in the development of relations between the two countries are formulated. Finally, it is concluded that the partnership between Russia and China is united by a common goal to resist the international system, which is dominated by the West. Their relationship is tactical and opportunistic, but increasingly compatible with economic, political and security interests.

For the purpose of learning multidimensional models, difficult for perception, representations and technology (device) of the description and measurement of volume and amount of the substance filling the volume of multidimensional objects are considered. Alternative options of multidimensional set of one-dimensional models and unified multidimensional model of three-dimensional objects are compared. The technology of measurement of multidimensional volume and amount of the substance that fills volume is shown. The authors came to the conclusion when transferring from a set of coordinate vectors of material points in complete spatial angle 4π steradian to multidimensional model of in pairs orthogonal vectors, calculation of volume of a multidimensional object significantly becomes simpler. The conclusion is that potentially infinite-dimensional model of an object represents the sphere in which balk of volume, the quantity and energy of the substance filling volume are entirely concentrated on its surface.

In this paper, the authors propose a new approach to the consideration of the friction phenomenon in HEAs and, in particular, dry friction.

Проектирование энергоэффективного дома – это комплексная работа, учитывающая рациональный выбор теплозащиты ограждающих конструкций, выбор инженерного оборудования и эффективность использования источников энергии. Энергоэффективность имеет два аспекта. Первый аспект – это характеристики ограждающих конструкций, т.е. чем лучше характеристики у теплоизоляционного материала, тем меньше энергии необходимо на отопление дома в холодный период года и на его кондиционирование в течение теплого периода. Второй аспект – это обеспечение дома недорогой энергией, а также их рациональное использование. Рациональным и экономически целесообразным способом повышения энергоэффективности здания является сочетание конструктивных и инженерных мероприятий, при одновременном использовании современных энергосберегающих технологий. Автор статьи отмечет, что проектирование энергоэффективных зданий – одно из самых приоритетных направлений в современной архитектуре. Энергоэффективное строительство – это забота о будущем нашей планеты, о будущих поколениях.
