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.

Redox processes provide the entire metabolic complex of warm-blooded organisms, while producing a significant amount of free radicals. Free radicals, despite their huge positive role in the body, are capable of forming conditions for the development of various pathogenetic conditions in the event of malfunctioning of the antioxidant defense. The state of homeostasis is indirectly monitored by the hematological characteristics of the blood, which makes it possible to use this aspect to analyze the physiological activity of the body's defense systems. The aim of the study was to study the reactive changes in the morphological composition of rat blood under the influence of quercetin, as a highly effective antioxidant.

Blood, as the internal environment of the body, is highly reactive and instantly reacts to the effects of various factors. As a system, blood is not only a self-regulating structure, but also a complex complex of components that are included in the system and dropped out of it as “requests” from tissues and organs. The level of functional activity of the blood system can sharply increase with deviations of physiological functions from the level optimal for metabolism. The aim of the study was to study the reactive changes in the morphological composition of rat blood under the influence of black chokeberry meal as a potential source of biologically active substances.

Based on the physical model of «unpacking» a fluid, published in 1983 to explain the physical nature of surface tension, an explanation of capillary phenomena was proposed. The unified physical nature of the condensation process and the processes in the capillaries expressed in terms of the surface tension of the liquid is proved. To prove the applicability of the «unpacking» model for capillary phenomena, an empirical Borelli-Jurin formula for determining the height of fluid lifting in capillaries was theoretically derived depending on the magnitude of the surface tension. The assumptions under which the formula is obtained are indicated. In addition, the article proposes a new formula for determining the maximum height of liquid lift in the capillaries, depending on the critical temperature of the liquid and the molecular weight of the liquid.

According to the properties of melting points and boiling points of the elements of the periodic table of D.I. Mendeleyev the application of the unpacking hypothesis of the substance was verified. The article contains the results of the verification. In general, according to the data for 98 substances taken from the information in Internet, convergence of results with an error of up to 40% for 73 substances was obtained. The effect of periodicity on the result is found. An exception to the calculated dependences was obtained for ten substances: noble gas and most halogens. A large discrepancy between the theoretical formulas and the reference data was also caused by the 14 elements of the middle groups.

The article proposes a method for calculating the taxonomic formula for the geoecological hazard of the cadastral district. The engineering-geological zoning map uses for calculating the balance of the territory by the hazard index – the basis of the taxonomic formula. The taxonomic formula as an open data set makes it possible to characterize the geoecological hazards of the territory of a district. The geoenvironmental hazard map of cadastral districts is necessary for regional model of spatial planning at the municipal level.

The article provides the research relating to the reaction of a new wheat variety “Ekaterina” to the application of chemical and biological plant protection agents and growth stimulants. The high ecological and climatic adaptability of Ekaterina wheat variety has been revealed and this is reflected in an insignificant decrease in crop yields (12–14%) under unfavorable conditions of cultivation in comparison with favorable conditions. The Ekaterina wheat variety have been processed with Grandsil Ultra, Zircon, Izagri Fors, Novosil preparations. This seed processing showed high efficiency during cold wet weather and hot dry-growing season. The effective seed processing of Ekaterina wheat variety with the Rostock, Fitolavin and Strekar preparations has been revealed only during extreme weather conditions.

The article contains a strict description of a situation in which the conditional probability of one event relative to another can be calculated as the probability of the first, provided that the second occurred. This gives a theoretical justification for the solutions of probabilistic problems using the concept of conditional probability.

This article describes some techniques that allow student to solve complex (seemingly) the task of science is not only without using a calculator, but even without performing complex mathematical calculations, allowing several times to reduce the time devoted to the solution of similar problems in the Unified State Exam.

We received theoretical formulas of the interconnection between melting, boiling and critical temperatures. Uniform physical representation of melting, boiling and evaporation processes was the basis for deriving the formula of interconnection between them. We use the concept of the material substance internal energy in terms of the molecules “unpacking” idea. The reference manual data on 85 substances from 13 to 855 degrees Kelvin confirms the theoretically derived formulas. We carried out the comparison of theoretical formulas and experimental data by their mean values. A simple ideal substance model with spherical molecules was considered as a model of substance molecule. The melting point is 1/3, and the boiling point ranges from 1/2 to 2/3 of the critical point for this model.
