THE SHARED RESEARCH FACILITIES "GEOSPECTRUM" OF THE GEOLOGICAL INSTITUTE SB RAS

The Shared Research Facilities "Geospectrum" of the Geological Institute SB RAS (Ulan-Ude) was created based on the analytical base of the Geological Institute SB RAS (GIN SB RAS, Ulan-Ude). Its equipment is used for isotopy of light elements, U-Th-Pb geochronology of igneous, metamorphic and sedimentary rocks. In addition, a large volume of mineralogical and geochemical research is carried out to solve petrological, geochemical, lithological-geochemical and environmental basic and applied problems

Transformation of Barguzin Buryats’ traditional values in late XX – early XXI centuries

Article analyzes the process of transformation in traditional values of Barguzin Buryats in late 20th – early 21st centuries. Family values, children, and knowledge of their own history and native language and religion are considered

Rituals of worship towards Goddess Yanzhima in the Barguzinsky District of the Republic of Buryatia

Annual three days rituals of worship towards Buddhist goddess Yanzhima in the Barguzinsky and Kurumkansky districts of the Republic of Buryatia are considered in the article: the ritual of worship towards water spirits "LusuudTakhilga”, the ritual of worship towards the owner of the mountain "Barkhan-Uul”, praying and worship towards Goddess Yanzhima and the celebration of her appearance on the sacred stone

Properties of gallium oxide films obtained by HF-magnetron sputtering

The results of an analysis of structure and phase composition of gallium oxide films obtained by HF-magnetron sputtering are presented. It is shown that in the interval 290–350 K, the increase in the film conductivity with increasing temperature is due to the excitation of electrons from a local level Е t located 0.95 eV below the conduction band bottom

Atmospheric Air Pollution by Stationary Sources in Ulan-Ude (Buryatia, Russia) and Its Impact on Public Health

For the first time in the territory of the Russian Far East, a study related to the establishment of correlations between air quality and public health in Ulan-Ude (Buryatia, Russia) was carried out. This study is based on the analysis of official medical statistics on morbidity over several years, the data on the composition and volume of emissions of harmful substances into the air from various stationary sources, and laboratory measurements of air pollutants in different locations in Ulan-Ude. This study confirmed that the morbidity of the population in Ulan-Ude has been increasing every year and it is largely influenced by air pollutants, the main of which are benzo(a)pyrene, suspended solids, PM2.5, PM10, and nitrogen dioxide. It was found that the greatest contribution to the unfavorable environmental situation is made by three types of stationary sources: large heating networks, autonomous sources (enterprises and small businesses), and individual households. The main air pollutants whose concentrations exceed the limits are benzo(a)pyrene, formaldehyde, suspended particles PM2.5, PM10, and nitrogen dioxide. A comprehensive assessment of the content of various pollutants in the atmospheric air showed that levels of carcinogenic and non-carcinogenic risks to public health exceeded allowable levels. Priority pollutants in the atmosphere of Ulan-Ude whose concentrations create unacceptable levels of risk to public health are benzo(a)pyrene, suspended solids, nitrogen dioxide, PM2.5, PM10, formaldehyde, and black carbon. The levels of morbidity in Ulan-Ude were higher than the average for Buryatia by the main disease classes: respiratory organs—by 1.19 times, endocrine system—by 1.25 times, circulatory system—by 1.11 times, eye diseases—by 1.06 times, neoplasms—by 1.47 times, congenital anomalies, and deformations and chromosomal aberrations—by 1.63 times. There is an increase in the incidence of risk-related diseases of respiratory organs and the circulatory system. A strong correlation was found between this growth of morbidity and atmospheric air pollution in Ulan-Ude
