The local crystallization in nanoscale diamond-like carbon films during annealing

The local crystallization during annealing at 600° C in nanoscale diamond-like carbon coatings films grown by pulsed vacuum-arc deposition method was observed using modern techniques of high-resolution transmission electron microscopy. The crystallites formed by annealing have a face-centred cubic crystal structure and grow in the direction [011] as a normal to the film surface. The number and size of the crystallites depend on the initial values of the intrinsic stresses before annealing, which in turn depend on the conditions of film growth. The sizes of crystallites are 10 nm for films with initial compressive stresses of 3 GPa and 17 nm for films with initial compres- sive stresses of 12 GPa. Areas of local crystallization arising during annealing have a structure dif- ferent from the graphit

Nanometer-sized carbon coatings on a silicon wafer: the effect that nitrogen doping level has on specific conductivity and morphology

yesThe dependences that the specific conductivity has on nitrogen pressure and thickness show nonlinear behavior; correlations between the coating morphology, specific conductivity, and plasmon energy are revealed. An explanation for the results is proposedBelgorod State Universit

Medical-Environmental Assessment and Forecasting of Socially Significant Pathology of the Population of the Republic of Dagestan

Aim. The environmental-epidemiological monitoring of socially significant pathology and its forecasting for the development of effective preventive measures and environmental quality management methods in the Republic of Dagestan.Material and Methods. An epidemiological analysis of public health indicators was carried out in 41 municipalities and 10 urban districts of the Republic of Dagestan. This was carried out through current and retrospective analysis of regional health indicators, medical-geographical and mathematical statistical analysis. The data sources for the main indicators reflect the epidemiological situation in the Republic of Dagestan from 1997 to 2016.Results. An understanding of the status of the main epidemiological indicators of the condition of public health of the region's rural and urban population was obtained and future dynamics predicted. An integrated assessment of the well-being of the territory of the republic revealed areas and cities with adverse trends in public health in the main groups of socially significant and environmentally-related pathologies.Conclusions. An integrated assessment of the state of well-being in the Republic of Dagestan by groups of epidemiological indicators of general morbidity, general morbidity of various age groups of the population, socially significant and environmentally-caused morbidity, as well as a forecast of their dynamics, revealed adverse trends in public health in rural populations of Tsuntinskiy, Akhtynskiy, Gunibskiy, Kulinskiy, Tabasaranskiy, Nogayskiy, Novolakskiy, Suleiman-Stalskiy, Khasavyurtskiy, Tarumovskiy districts and of the cities of Kaspiysk, Dagestanskie Ogni, Makhachkala and Kizilyurt. An analysis of the sources of supplies of drinking water revealed a positive correlation between heavy metals content and adverse trends in socially significant pathology in the regions of Northern Dagestan
