“…The second physical explanation for the IR generation is the increase in the intensity of vibrations of GE atoms and molecules with a gradual increase in gravitational energy with depth, which changes the Debye temperature in the case of an increase in all-around compression. In this case, each GE point is a stable generator of thermal energy, which can be reduced only by reducing the geostatic bulk pressure [22].…”

The concept of energy supply is widely discussed, but there is no consensus on ways of its provision. In the current research, we have provided an analysis of available combinations of renewable sources for decentral- ized energy supply. It is important for critical facilities on territorial society and district levels. The article considers the safety of the technical component of a complex organizational and technical system by studying the functional relationship between the parameters: temperature, time, active power, hydrogen participation, etc. The idea of the work is to evaluate the ratios of generating capacities of different types of renewable sources in complex systems and select highly efficient technologies and energy means for decentralized energy supply.

This work aims to measure the total and spectral reflectance of visible radiation by various coat colors of cattle. It came to the interest of the author to determine also the reflectance by muzzle, a hairless pigmented portion of the integument. Measurement of the total and spectral reflectance of visible radiation, 400-700 nm, by cattle coat and muzzle was conducted using the integrating sphere and spectroradiometer. The total reflectance of visible radiation by black, brown and white coats were 77%, 11.68% and 65.76% respectively. Total reflectance values for muzzle were 11.5%, 34.61% and 22.l % for black, brown and brown-black muzzle respectively.

This paper presents new scientific results of experimental studies that refute the generally accepted fact that the coat solely protects animals from the effects of solar energy. The purpose of this study was to confirm the fact of the spread of optical radiation energy under the animal’s skin along individual hairs, as light guides. The authors of this study experimentally determined the optically conductive structure of an individual wool hair, the components of the transmission parameter of an individual wool hair, namely the coefficient of light transmission inside the wool hair, the coefficient of attenuation of internal light transmission by the substance of the wool hair, the coefficient of losses in the middle of the cylinder of the wool hair due to the beam scattered in the internal structure and the refractive index of its outer shell. Based on the use of methods of photometry and geometric optics, theoretically substantiated and experimentally obtained results regarding the establishment of a mathematical dependence of the total amount of optical radiation energy entering the hair cylinder on the value of the angle of incidence of the beam on the surface of the hair, the cleanliness of the inner core of the cylinder structure, the length of the light-conducting section to the surface of the skin, as well as the refractive index of its outer shell. Based on the results of experimental studies, mathematical dependencies were obtained that describe the spectral light-conducting properties of an individual hair, as well as the distribution of energy emitted in the thickness of the skin along the entire length from the point of penetration into the hair and to the follicle – the place of use of optical energy in photobiological processes. The obtained results of experimental studies of the passage of optical radiation energy along the length of a single hair into the body of an animal are of practical importance for photobiologists investigating the effect of optical radiation from the Sun on biological objects of animal origin.
