The new algorithm is presented in this paper for the express estimation of the basic properties of the components of binary systems that are sources of gravitational waves, using the tools of classical mechanics, the Doppler effect, and the Hubble law. A brief overview of the chronology of the gravity theories formation is shown. The basic principles of the General Relativy theory are cosidered. The main difficulties in the registration of gravitational waves and the prospects for their future research are shown and analysed. The model of binary system are formulated in the paper. The problem of the masses, radii and distance determining to the bodies of the system is resolved according to observations. The maximum radiation power of gravitational waves, the rate of mutual incidence of bodies and the initial distance between the components are calculated. The properties of the formed body were investigated, in particular, the total energy of the emitted gravitational waves was determined in the process of merging bodies, its mass and angular velocity of rotation were determined. A numerical analysis of the results was performed for four events: GW150914, GW151226, GW170104, GW170814. The analysis showed that all the new results obtained using the new algorithm are absolutly consistent with the exact results of the predecessors works, within the error of their definition. It is obvious that is evidence of the efficiency of the algorithm. At the same time, this algorithm is only an effective estimative and operational tool. The algorithm is available for independent estimation studies, even by non professionals. It can also be an effective evaluative tool in the hands of professionals when researching new gravitational events.

Growing vegetables in suburban areas and farms provides the population with high-quality vitamin products, but a prerequisite for this is the use of quality seeds. The article presents the data obtained in the laboratory study of samples of tomato and pepper seeds supplied to the population by various firms and manufacturers. To assess the quality of seeds, we used indicators of weight of 1000 seeds, germination, dynamics of germination (percentage of sprouted seeds by day), length of roots and shoots of seedlings for 4 and 6 days - for tomato seeds and for 11 and 13 days - for pepper seeds. For the studied samples, the weight of 1000 seeds in tomato averaged 2-2,5, in pepper - 6,5 g, the germination rates for tomato seeds in different varieties ranged from 30 to 100 %, varieties with germination of more than 80 % were 11 out of 17. The germination of pepper seeds in different varieties varied from 5 to 90 %, the seeds of one variety were dissimilar.

According to the system of life forms K. Raunkiaer on the Kuznetsov Mountain dominated by hemicryptophytes (148 species, or 55,4 % of the composition of the flora). The hemicryptophytes are significantly inferior in number phanerophytes (30 species, 11,2 %), terophytes (29 species, 10,9 %), cryptophytes (25 species, 9,4 %), terophytes-hemicryptophytes (22 species, 8,2 %), chamaephytes (11 species 4,1 %), hemicryptophytes-chamaephytes (1 species, 0,4 %) and сryptophytes-hemicryptophytes (1 species, 0,4 %). The absolute majority of species (225 species, 84,3 %) growing on the upland are resistant, highly resistant and super-resistant to local adverse climatic and weather conditions. Among these species are the hemicryptophytes, сryptophytes-hemicryptophytes, cryptophytes, terophytes-hemicryptophytes and terophytes.

This paper discusses the search for the characters of F.M. Dostoevsky's «lost identity» - finding God in his soul. As the study shows, the writer of the plot «leads» the heroes to the highest value through a number of specific states: dreams, duality, and passion for passion, the idea. It is established that the characters of F. M. Dostoevsky on the way of finding authentic identity falls into the «melting pot» (dreams, duality), where miracles of social transformations and spiritual transformations, «stratification» and assimilation happen to them: the heroes as a result receive an individual experience of mystical experience - encounters with the divine essence, o what and testify. The human soul is already interconnected with divine energy. It is this connection with the mysterial that determines the individual sense of personality, its identity. Sometimes this identity conflicts with the very essence of the hero and the hero is to some degree «divided» into two entities. This is precisely the reason for the phenomenon of dualism in the work of F. M. Dostoevsky.

The article deals with the problem of understanding reality by means of some artistic strategies, such as metabola, gap poetics and visualization. The paper gives an example of how A. Dragomoshchenko studies ongoing processes and phenomena inherent to the world, trying to build the logic of writing most adequate to the depicted reality by rethinking syntactic, semantic links which are standardized in the language. As a conclusion, this article proposes the thesis that the result of such rethinking is the experience of going beyond the ordinary understanding of the world, which is acquired by the author and the reader, and also formulates the idea of poetics of tangibility in texts aimed at de-automating of this kind of existence.

This paper presents the results of using chemical, physic-chemical and spectral methods for analyzing metals in their alloys, air, water. For each of the above methods, the feasibility of its use, advantages and limitations are discussed. It is shown that despite the widespread occurrence of chemical and physico-chemical methods of analysis, they should be recommended only when determining high concentrations of metals. To determine low concentrations of metals, modern spectral analysis methods should be used, which provide greater expressivity and accuracy.

In this article, we evaluated the effectiveness of the introduction of the latest information system in a restaurant. The relevance of automated control systems, first of all, determine corporate goals, such as the growth of an enterprise, making a profit, ensuring continuous operations, and increasing the market value of a company. The article proposes the implementation of Poster Pos information system in the enterprise - a system that stores data not on the server computer in the next room, but on hundreds of remote servers. In addition, all financial transactions, statistics and warehouse movements within the institution can be easily viewed in real time from anywhere in the world. Its advantages: low-cost equipment and maintenance; it can be installed without technical staff; it has a minimum payback period.

The article examines the signs of labor relations, allowing them to be identified within the framework of the concluded civil law contracts. On examples from judicial practice conditions of application of consequences of a recognition of the labor relations arising on the basis of civil-law contracts are shown. It is shown that if the court determines that the civil law contract actually governs the employment relationship between the employee and the employer, the provisions of the labor law and other acts containing labor law norms should be applied to such relationships, that is, the civil law contract can be retrained in an employment contract.

In the given paper we present a quantitative analysis of the evolution of a binary system ¾WASP-1-WASP-1b¿ with using a Minimal Model of Tidal Interaction. The brief overview of transit method and the basic projects of search and study of exoplanets based on this method are shown. The main physical parameters of the star and exoplanet are calculated and the observabales data are systematized. The general aspects of the tidal interaction theory are considered. The Minimal Model of the Tidal Interaction of two massive gravitating bodies are formulated here. The tidal torque and the tidal force for a slightly elongated ellipsoid are calculated. The differential equatuions of the binary system evoluton are constructed with using of the basic laws of mechanics. The initial conditions are given. A dimensionless procedure and algebraic reduction of the equations are realized here. Numerical analysis of the WASP-1 system evolution are represented. It is shown that the exoplanet will inevitably fall to the surface of the star and will be destroyed. The rest of lifetime of the exoplanet is about 873 My. The dependences of the radius of the orbit, stellar period of the star and orbital period of exoplanet from time are demonstrated graphically. It is shown that its orbital period will decrease from 2.52 days to 4.4 hours as a result of the exoplanet fall. The stellar period of the star will decrease on 7 days.
