The paper deals with a mathematical model and results of numerical experiments for studying the process of "oil-gas-water" mixture filtration in a porous medium to make concrete practical recommendations and administrative decisions. The developed mathematical support allows to define duration of reservoir operation time, depending on its length and capacity, number of wells and their production rates. Numerical calculations defined important parameters of the process their ranges. Results of numerical experiments were presented as graphics. On the basis of material balance equation there was shown suitability of the developed mathematical and software for calculation of pressure fields and saturation, as well as for calculating field development indicators in the "oil-gas", "oil-water" and "oil-gas-water" systems.

The article "Armenian separatism is an integral part of international terrorism" – describes the evil, from which has been suffered not by Azerbaijanis, Turks, Georgians, but also by many other innocent people around the world for hundreds of years. Armenian terrorist groups, distinguished by their cruelty, destroyed all those who prevented the realization of the pan-Armenian myth "Great Armenia - from sea to sea".

Methods of halogenation of cyclohexen involving glycidol were developed. During the reaction two isomers were formed: 1-(2-halogencyclohexoloxy)-2-bromine-3-hydroxypropane(I) and 1-(2- halogencyclohexoloxy)-2-hydroxy-3-brominepropane(II). It was found that the compound (I) forms an ethoxy compound, but the (II) compound doesn’t. During the reaction of ethoxy compund with hydrogen halide two products were derived that differed by the position of the halogen atom. When the mixture of cyclohexene and glycidol is chlorinated a similar course of reaction is observed which proves that the nature of halogen does not affect the joint halogenation reaction. In connection with the preparation of hard-to-divisible compounds, we have developed a method for the production of chloro-ethers by the reaction of the interaction of chloroamide of sulfonic acids with olefins in the presence of alcohols.

The study of parametric bifurcations of vector fields is an important problem in the theory of dynamical systems. The present work is devoted to the computer interpretation of qualitative behavior of solutions of a system of singularly perturbed nonlinear autonomous differential equations obtained from the Van der Pol oscillator. The system under consideration has a unique singular point which is of the hyperbolic type. Moreover, that point can be either nodes or foci only. The aim of the present work is to confirm these well-known results on computer.

The paper considers the integral equation of radiation transfer. Considered the problem of efficient modeling of propagation radiation in layered-homogeneous medium. Under these assumptions have been obtained approximate calculation formulas to estimate the values of functionals, having a physical means of the intensity of radiation and it’s derivative by dispersion coefficient. Further on is used the traditional method of addressing backward problems, based on the Newton-Kantorovich method.

The range of the products developed from goat milk, isn't so great now. Goat milk as raw materials is mastered only partially. However prospects of processing of goat milk are very wide that is connected with increase of the consumer demand, essential deficiency of cow milk and possibility of use of the available equipment. Development of the production technology of fermented milk beverages on the basis of goat milk will allow to expand the range of dairy products of dietary purpose of a domestic production. The technology of receiving fermented-milk beverages from goat milk with the saffron, having the general biological effect on an organism, on the intestines function, positively influencing its microbiocenosis and possessing immunomodulating action is developed that positively solves a problem of receiving drinks of treatment-and-prophylactic appointment.

A modern approach to the solution of problems of discrete mathematics due to the necessity of introducing and using known methods of solving problems. Existing programs and algorithms are not implemented to the extent necessary at the present time. The article is devoted to modeling and programming for Delphi and Maple for solving problems in discrete mathematics. The basis of research are well known and tested algorithms for the tasks of kommivojazhera – Greedy algorithm allows to find the optimal route.

The comparative analysis of a wide range of the modern medicines giving antiseptic properties to cotton fabrics is carried out. Primary benefits of silver nanoparticles, such as ecological safety, non-volatility and indifference in relation to resident microflora of the person are provided. Results of cotton fabrics processing by silver hydrosols with the subsequent fixing of a tanidama are shown. It is fixed that the developed technology allows to give to fabrics resistant antiseptic the effect which is remaining after several wet thermal treatments.
