LAMPENFLORA OF NOVOAFONSKAYA CAVE
DescriptionNovoafonskaya cave is located in Abkhazia. It is equipped for visits in 1975. The cave has permanently installed lighting. In caves with artificial lighting, a vegetation of cyanobacteria and algae, bryophytes and ferns can be found around lamps. The development of lampenflora is a typical problem for cave management. We have identified 69 species of phototrophs in Novoafonskaya cave: Magnoliophyta 2 species, Pteridophyta 6 species, Bryophyta 11 species, Cyanobacteria 34 species, Bacillariophyta 9 species, Ochrophyta 2 species, Chlorophyta 5 species. The article considers main habitat of lampenflora and gives their characteristics. We have also revealed predominance of cyanobacteria in the cave

EXPERIMENTAL RESEARCH AND MODELING OF PACLOBUTRAZOL MIGRATION IN SOIL
04.00.00 Geological-mineralogical sciences
DescriptionIn this study, we have investigated the migration of paclobutrazol in the sod-podzolics soils. The migration of pesticide was restricted with 5 cm in the field study. Paclobutrazol was found in 11 days after application in the lysimeter’s water samples, though the pesticide is moderately mobile. The lysimeter study showed that the risk of ground water contamination would exist if application of paclobutrazol was on the sod-podzolics medium loamy soils. The modeling by PEARL 4.4.4 and MACRO 5.2 simulated the migration of paclobutrazol until 18 cm in the soil. MACRO was able to predict the leaching of pesticide. The simulated paclobutrazol losses by leaching were consistently lower than the observed

Description
Considered in the study, there are specific features and stratigraphy of the snow cover in the region of the mountain claster of Sochi (Krasnaya Polyana) during winter of 2016-2017. We have analyzed patterns of snow thickness distribution, its dependence on the absolute elevation, slope exposition and landscape type. Conclusions were made about the necessity of the regular study of the structure and quality of the snow cover for the purpose of mountain skiing development

Description
In the article, we consider climatic conditions during the cold period of the year in the mountain claster of Sochi. We have analyzed variability of time series of air temperature and precipitation sums at meteostation Krasnaya Polyana. We have established, that average daily temperature in the cold period was growing during the last thirty years. This process was accompanied by decreasing of daily temperature amplitides. Winter of the year 2016/17 is characterized by early beginning of snow accumulation because of comparatively low temperatures in December 2016. This was the reason in general for comparatively more dense snow cover and to more frequent avalanches

Description
An analysis of the provisions of the Criminal Procedure Code and other regulatory legal acts relating to the investigation and operational investigation team activity shows that the head of the investigative and operational group exercises, among others, the organizational and managerial function. Consequently, these powers are not limited to procedural functions alone. In the proposed article, the author examines what these functions are and how they influence the procedure for investigating crimes

MATRIX ORGANIZATION OF SOILS OF RICE AGROLANDSCAPES
06.00.00 Agricultural sciences
DescriptionAcidic properties of the mineral matrix of meadow chernozem and meadow-boggy soils of Krasnodar region are characterized by a total adsorption capacity of ammonia in the range of 32-61 µmol / g. The lowest acidity of the matrix was observed under conditions of permanent rice cultivation for 80 years (32- 33 µmol NH3/g). The mineral matrix of rice soils depends on the meliorative state and the granulometric composition of these soils. At low fields of meadowboggy soils, heavier in granulometric composition, the total acidity of the mineral matrix is 51- 53 µmol NH3/g on high checks of lighter meadow chernozem soils – 34-45 µmol NH3/g. In the upper soil, with a less acidic matrix, the Fe3+ content increases and the amount of Fe2+ decreases. The reverse pattern is found in the lower soil with more pronounced acidic properties of the matrix. A proportional relationship between the humus content and the acidic properties of the mineral matrix is found. The highest yield of rice is formed on meadow chernozem soils with a less acidic mineral matrix
