There was no regular change in the content of elements in leaves of dwarf shrubs with distance from the source of emission. The differences in the sulfur content in leaves of dwarf shrubs for 2009 and 2018 were within the error limits. No significant differences were found in the values of the mass fraction of nitrogen in blueberry and lingonberry leaves for pine stands located at different distances from the emission source. The nitrogen content in lingonberry leaves was significantly lower than that in blueberry leaves for both observation periods.

The main focus of the article is the application of tests on the Moodle platform in order to optimize the educational process and assess the performance of students of technical specialties. The study is the results of a survey of university teachers and students of Institute for Cybersecurity and Digital Technologies and Institute for Advanced Technologies and Industrial Programming of MIREA – Russian Technological University on the use of Moodle and the use of tests to assess knowledge. The work also covers various aspects of the use of Moodle in the educational process, focusing on the development of practical skills and effective assessment of learning achievement. University teachers shared their experience of using Moodle for educational purposes, identifying the advantages and features of introducing test items in the system. The students expressed their opinion about the perception of the platform as well as the level of satisfaction. The results of the survey were presented as quantitative and qualitative data and subsequently analysed statistically.

This oxbow was formed as a result of the Saratov reservoir creation and located within the Krasnoglinsky District of the Samara city. The study was conducted in 2021 and 2022. Four trial plots were established in the oxbow of the river; the control plot was a sample area allocated in the Saratov reservoir, in the immediate vicinity of the oxbow. The quantitative determination of heavy metals and metalloids content in bottom sediments was carried out using inductively coupled plasma spectrometry. The results obtained showed that specific conditions arise in each research period that affect the studied elements accumulation in the oxbow bottom sediments. These processes are influenced by the location of the sample plot in the oxbow, the flow degree, the spring flood nature, the anthropogenic transformation and the overgrowth of Typha angustifolia L. For all sample plots located in the oxbow, higher concentrations of most of nalyzed elements were detected in 2022. Heavy metals and metalloids accumulated especially actively in the bottom sediments of sample plot 4, located in the oxbow behind an artificial dam and characterized by the weakest flow. The soil cover of Samara city posesses weak and moderate effect on the quantitative characteristics of metal accumulation in the oxbow bottom sediments. Compared to the control, the studied elements accumulated more actively in the bottom sediments of all oxbow sample areas, which confirms the accumulative nature of river oxbow of varying degrees of isolation.","PeriodicalId":21482,"journal":{"name":"Samara Journal of Science","volume":"21 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141645852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This group of dipterans includes small insects that can be observed in natural biotopes from September to April.

Insects were collected in various natural communities using Barber traps installed there, as well as by route method. At the time of collection, environmental factors such as temperature, humidity, and light were recorded. The last revision of this group of dipterans for Russia was carried out in 2013 by A.V. Petrashiyunos and N.M. Paramonov. According to their data, the trichocerid fauna of Russia at that time consisted of 27 species. As a result of our research, 11 species of mosquitoes from the genus Trichocera were discovered in the European part of Russia. These are Trichocera hiemalis, Trichocera inexplorata, Trichocera major, Trichocera parva, Trichocera recondita, Trichocera regelations, Trichocera saltator, Trichocera sparsa, Trichocera brevis, Trichocera implicata, Trichocera altipons. For the first time in Russia, three species were identified: Trichocera brevis, Trichocera implicata, Trichocera altipons. Having analyzed the habitats of the studied group of trichocerid species, we found that 1 species has a circumpolyzonal type of habitat, 1 species has a sub-holarctic type of habitat, 1 species has a transpalearctic polyzonal type of habitat, 2 species have a trans-eurasian polydisjunctive type of habitat and 6 species have a European type of habitat.","PeriodicalId":21482,"journal":{"name":"Samara Journal of Science","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141644110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the course of the study, using new data from archival documents, it was possible to establish the dates and features of the election campaigns to the Soviet authorities in 1947, 1950, 1953. It was noted that regular election campaigns contributed to increasing the political knowledge of citizens, introducing them to Soviet political culture, and also formed a «positive image» of the authorities in the eyes of Soviet citizens. At the same time, election campaigns revealed that Soviet citizens had a number of critical comments about the nominated deputies, which suggests the existence of dissatisfaction with certain aspects of everyday life that did not affect the main directions of Soviet state policy.","PeriodicalId":21482,"journal":{"name":"Samara Journal of Science","volume":"20 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141646225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest biomass of benthos was noted in oxbow lakes, and its abundance was found in beaver ponds. An analysis of the ecological groups of zooplankton and benthos by type of nutrition was carried out. In autumn, the composition of zooplankton was marked by a predominance of vertical feeders and primary filter feeders in beaver ponds, primary filter feeders and predatory forms in ditches, primary filter feeders and vertical feeders in oxbow lakes, and secondary filter feeders, scrapers, detritivores and stand feeders in hollows in wetlands. The benthos of beaver ponds and oxbow lakes contains all six ecological groups of benthos based on feeding type. There are no collectors, obligate filter feeders or active predators in the ditches.
