We are not interested in the myths and misty legends presented as truthful. For example, we consider the question of the existence of souls and spirits as a scientific problem and are not in a hurry to adopt a point of view before research in this field is progressing. As proofs of the existence and survival of a soul or the souls of a man are not convincing, instead of thinking a lot about the possibility of entering a hypothetical paradise after death and escaping the hell, we are interested in research aimed at the prolongation of human life and even in the different possibilities of attaining immortality, the problems of salvation of mankind and the more general problem of development of the Mind in the Universe.
Нас не интересуют мифы и легенды, представленные как правдивые. Например, мы рассматриваем вопрос о существовании душ и духов как научную проблему и не торопимся принимать какую-то точку зрения, пока исследования в этой области не прогрессируют. Поскольку доказательства существования и выживания души или душ человека неубедительны, вместо того, чтобы много думать о возможности попасть в гипотетический рай после смерти и избежать ада, мы заинтересованы в исследованиях, направленных на продление жизни и даже в различных возможностях достижения бессмертия, проблемах спасения человечества и более общей проблеме развития Разума во Вселенной.

The group composition of asphaltene-resin-paraffin deposits (ARPD) in the Irelyakh field and their solubility in the composite solvents on the hexane base with the additives consisting of nonionic surface-active substances (NSAS) and concentrates of aromatic hydrocarbons is determined. The results of the investigations show that the additives Neonol AF-9-10 and liquid products of pyrolysis (LPP) are most efficient. The use of these additives allows to increase the efficiency of ARPD breaking and dissolving by 1,3 – 1,6 times as compared with a base solvent. It is shown that the increase in the concentration of individual additives from 0,5 to 3 % causes a decrease in the efficiency of detergent compounds.

Riesz potentials are convolution operators with fractional powers of some distance (Euclidean, Lorentz or other) to a point. From application point of view, such potentials are tools for solving differential equations of mathematical physics and inverse problems. For example, Marsel Riesz used these operators for writing the solution to the Cauchy problem for the wave equation and theory of the Radon transform is based on Riesz potentials. In this article, we use the Riesz potentials constructed with the help of generalized convolution for solution to the wave equations with Bessel operators. First, we describe general method of Riesz potentials, give basic definitions, introduce solvable equations and write suitable potentials (Riesz hyperbolic B-potentials). Then, we show that these potentials are absolutely convergent integrals for some functions and for some values of the parameter representing fractional powers of the Lorentz distance. Next we show the connection of the Riesz hyperbolic B-potentials with d’Alembert operators in which the Bessel operators are used in place of the second derivatives. Next we continue analytically considered potentials to the required parameter values that includes zero and show that when value of the parameter is zero these operators are identity operators. Finally, we solve singular initial value hyperbolic problems and give examples.
