Description: The available up-to-date equipment allows us to perform various research tasks using modern scientific tools. The article shows examples of how data on the composition of stable isotopes can be used in biology, environmental studies, archeology, and paleoclimatology. In addition to stable isotopes, radioactive isotopes 14 C and 3 H are studied. An 1220 Quantulus spectrometer-radiometer is used to determine their specific activity. Investigations on the tritium specific activity in aqueous samples and tritium water isolated from tree ring cellulose on background and anthropogenically loaded sites are carried out. An analysis of carbon specific activity allows performing radiocarbon dating of bottom sediments, peat deposits, and archaeological samples. A qualitative elemental analysis is carried out using a Hitachi TM-1000 microscope equipped with an X-ray spectral analyzer.

Description: This article shows the potential of using δ 13 C values of pollutants in snow pack to study the human impact on the environment of Tomsk and its surroundings. We believe that it is possible to use a relation between the isotope compositions of a fuel and black carbon for establishing the origin of the latter. The main object of our investigation was dust accumulated by the snow pack in the winter of 2015-2016. The study of dust samples included the following steps: determination of the total carbon content in snow pack samples of Tomsk and its surroundings, extraction of black carbon from the dust, as well as the determination of δ 13 C values of the total and black carbon accumulated in the snow pack. A snow survey was carried out on the 26th of January and on the 18th of March. The relative carbon content in the dust samples was determined by using an EA Flash 2000 element analyzer. It varied from 3 to 24%. The maximum carbon content was in the dust samples f...

Description: Establishing the new society is accompanied by a global intellectualization of the entire economic system influencing the development of information, scientific and innovative branches of the indusry. The key factors of the society develpment are information and knowledge. An important quality of a modern employee is the ability for continuous training. Currently, the interest to education has significantly increased as well as the demand for education and the educational level of employees. Education is one of the most vital values, meeting the natural needs of humans in the knowledge of the external world and themselves. The growth of social demand for education in the evolution of social development has led to the gradual transformation of the elite educational institutions into the institutions for everyone. For most people nowadays, higher education has become not only sustainable, but one of the most significant values. The successful development of knowledge-based economy...
