The main direction of breeding in melon farming is the creation of varieties with high potential for productivity. The research was conducted at the Bykovskaya experimental station in the Volgograd region. The aim of the research was to create a new competitive watermelon variety malachite, which has a complex of useful and economic characteristics, resistant to biotic and abiotic environmental factors. The characteristic of the initial forms used for hybridization is given. The data of evaluation of the hybrid combination in all stages of the breeding process. According to the results of the 3-year competitive variety testing, the excess of the yield of watermelon malachite over the Sinchevsky standard averaged 1.5 t/ha. The dry matter content for all years of research was at the level of the standard and ranged from 11.4 to 12.4%. The final result of breeding work is the creation of mediumgrade watermelon malachite, which is in the state variety testing.

Breeding Techniques

Global experience related to increased pork production shows that breeding work has become an integral part of the technology, since it is impossible to further improve breeding and performance traits of animals without it and therefore the greater production of better quality pork. The paper presents the results of the breeding process arrangement for creation of F1 parental pig. Substantiation of breeding techniques when creating the final parental groups of sows (F1) with a high adaptive ability was based on complex methods to evaluate breeding animals, including traditional methods of domestic breeding and breeding indices. Evaluation of combination compatibility of breed-linear hybrids with the use of breeding indices during mating of parent initial forms allows to determine efficiency of using Yorkshire sows with Landrace boars, and Landrace sows with Yorkshire boars (final parental sows (F1)), which had significantly better reproductive indicators in comparison with BLW х BM genotype sows. Particularly efficient compatibility was recorded when selecting Yorkshire sows and Landrace boars. It was determined that in modern conditions an increase in the efficiency of breeding and pedigree work in pig breeding was based on the use of genetic methods, including: individual assessment of pedigree species according to the main breeding traits, evaluation of genome of each breeding animal, and use of breeding indices allowing to identify the true genetic potential of animals and predict performance traits of their offspring. The research relevance lies in using the innovative methodology for comprehensive assessment of combination compatibility of parental pairs, unified for pig husbandries and pig farms, which will make it possible to 10% accelerate the breeding process of forming the final parental forms of sows, ensure obtaining offspring with predictable reproductive, fattening and meat traits, and good adaptive ability.

This study aims to obtain data on changes in function and initial forms of performing Lebon in the community, Pepedan Village, Parigi District, Pangandaran Regency. This study uses a qualitative descriptive approach. With the development of the current era through various factors, the Lebon art has turned into a means of entertainment that is arranged in such a way that the aim of the Lebon art remains sustainable and is accepted by the Papedan community. Lebon art in the language of the local community lebon has a meaning that is grave or buried. Lebon art performance can occur because there are two groups fighting over plantation land ownership or fighting over women to be wives, Lebon art is art that contains violence in earlier times, because in this art required as winners are surviving champions and losers must reach die and be buried in the place of the Lebon art performance. Lebon art in general Pangandaran community has become an art that was born originally from Pangandaran Regency.

The aim of the study was to investigate the prevalence of generalized periodontitis depending on age and biotype of periodontium. Materials and methods: We examined 855 males aged 20-55 years, who were divided into 2 groups: the main group – 570 surveyed with a generalized periodontitis, the comparison group – 285 dental healthy individuals.The diagnosis of generalized periodontitis was established by the classification Danilevsky M.F. (1994) and refined by using paraclinical indices. The periodontal biotype was determined using Hu-Friedy Colourvue Biotype Probe. Results: As a result of the conducted researches was establish, in the carriers of blood group O (I) and A (II), developed forms of generalized periodontitis were found, on average, 2.7 times more often than the initial forms of the disease. Instead, at the representatives of B (III) and AB (IV) groups blood the frequency of initial GP – I degree was on average, 1.2 times greater than the prevalence of developed forms of generalized periodontitis. Also as a result of our researches, we found that the cluster A1 had 39.30% patients, cluster A2 was found at 28, 77%, and cluster B – 31.93% of the total number of patients with generalized periodontitis. Conclusions: As a result of our research, it was found that in the carriers of the blood group O (I) and A (II), more advanced forms of generalized periodontitis were observed, which was confirmed by the presence of the biotype of the periodontal disease in the cluster A1 and A2.

Initial Forms

We consider fretting wear due to superimposed normal and tangential oscillations of two contacting bodies, one of which is an elastomer with a linear rheology. Similarly to the contact of elastic bodies, at small oscillation amplitudes, the wear occurs only in a circular slip zone at the border of the contact area and the wear profile tends to a limiting form, in which no further wear occurs. It is shown that under assumption of a constant coefficient of friction at the contact interface, the limiting form of the wear profile does depend neither on the particular wear criterion nor on the rheology of the elastomer and can be calculated analytically in a general form. The general calculation procedure and explicit analytic solutions for two initial forms, parabolic and conical, are presented for various combinations of frequencies and phases of normal and tangential oscillations as well as for various linear rheologies of the elastomer.

The City

The emergence of gay identities in Istanbul is often regarded as a practical result of mobilisation by minority sexual rights NGOs. Indeed, Istanbul Pride emerged in the early 2000s as a widely-referenced exemplar of the political promise of street-level activism in Turkey. Tracing how gay initially was used in the nightlife market around İstiklal Street and reconstructing the early history of agitation for an annual Pride march, I argue that street traders and small-scale entrepreneurs, not street-level campaigners, have played the critical role in prising open spaces where men could come to identify themselves and be identified as gay. Moreover, spaces afforded by particular fixed-place businesses in the nightlife market critically shaped the initial forms of political association involving gay men that were able to develop and consolidate in the city.
