Settlement system of the Kazan county in the middle of the XIX century

The urgency of the problem under investigation is caused by the fact that the system of the settlement is the basis and the indicator showing the change in the spatial characteristics, as well as a measure and the reflector of the nature of social and economic processes in a particular area, in this case - Kazan County. The purpose of the article is to familiarize with the first attempts to implement spatial and statistical analysis of data on rural settlement in the middle of the XIX century using the methods of modern computer technology. Leading techniques to the study of this problem are the methods of spatial and spatial-statistical analysis of the data. To visualize the settlement structure of the Kazan district an electronic cartographic base was used, established on the basis of the map of 1910. The localization of the settlements accounted by the Ministry of Internal Affairs in 1859, and a spatial analysis of the current settlement system revealed the areas of the greatest concentration of the settlements, relatively uniform distribution of settlements on the existing three county units of the County and uneven distribution of different their types, socio-ethnic and religious heterogeneity of the population, the direction of the main vector of economic and economic development, the beginnings of the industrial production in the county. Study materials are the most time-consuming and defining step in the creation of the historical geographic information system (GIS).The author(s)

Neotectonic factors affecting geometry of plains

© SGEM2015. The objective of this research is to expand our understanding of how endogenous processes influence development of erosion systems. Study of the East European Plain allowed the authors to collect a large amount of data, which show that the life cycle of erosion system is controlled not only by the ‘obvious’ factors (runoff volume, slope, rock type, etc.) but also by large-scale processes forming the face of the Earth. Such processes, according to the authors, first of all, involve tectonic events that are manifested by vertical movements of crustal blocks and account for formation of uplands and slopes. The authors used a complex technique to check their assumptions, including methods of qualitative and quantitative evaluation of upper crust deformations using archive aerial and satellite images (evolution or degradation of more than 200 gully systems were observed through a series of aerial and satellite images taken in 1953, 1980 and 2008) and morphometric analysis of digital elevation models to create a model of neotectonic activity in the studied territory (hilly plateau in the east of the East European Plain). The authors also found that there is a direct association between neotectonic activity and modern geodynamics: areas with stable or constantly degrading erosion systems are related to neotectonically calm territories, while areas with active dynamics are usually located in close proximity to the medium- and high-amplitude neotectonic uplifts

Employment of geoinformation technologies in historical researches experience of Kazan (Volga Region) federal university

© The author(s). Relevance of the topic is due to the prevailing in modern science trend - complex study of society, not only in time but also in space, established thanks to the convergence and integration of Arts and Sciences. The paper aims to describe our own experience of association within the framework of a single information field of full-text data sources, mainly registration, accounting and statistics data (cadastres, scribe and census books) and maps to represent in terms of spatial coordinates the social stratification of the city Sviyazhsk and its surroundings in the XVII century. The leading method in the research of this problem is that of geo-information technologies. The main results of this work were the establishment of historical sources database of the period under study, data formalization of the written sources, compiling the geographic basis of geo-information system (GIS), digitization and creation of vectorized base of geo-data (BGD), which allows to localize and identify the settlement of Sviyazhsk County. The paper materials will be useful for further research and for model development of a settlement structure, farm tenure and land use, social stratification of the population and multifaceted relationships of towns and villages (peasantry) in the Middle Volga area in the second half of the XVII century

The authors propose an complex method of estimating the deformation of the upper part of the crust

Deoxygenation affects composition of membrane-bound proteins in human erythrocytes

Background/Aims: ATP release from erythrocyte plays a key role in hypoxia-induced elevation of blood flow in systematic circulation. We have previously shown that hemolysis contributes to erythrocyte ATP release triggered by several stimuli, including hypoxia, but the molecular mechanisms of hypoxia-increased membrane fragility remain unknown. Methods: In this study, we compared the action of hypoxia on hemolysis, ATP release and the composition of membrane-bound proteins in human erythrocytes. Results: Twenty minutes incubation of human erythrocytes in the oxygen-free environment increased the content of extracellular hemoglobin by ∼1.5 fold. Paired measurements of hemoglobin and ATP content in the same samples, showed a positive correlation between hemolysis and ATP release. Comparative analysis of SDS-PAGE electrophoresis of erythrocyte ghosts obtained under control and deoxygenated conditions revealed a ∼2-fold elevation of the content of membrane-bound protein with Mr of ∼60 kDa. Conclusion: Deoxygenation of human erythrocytes affects composition of membrane-bound proteins. Additional experiments should be performed to identify the molecular origin of 60 kDa protein and its role in the attenuation of erythrocyte integrity and ATP release in hypoxic conditions

A Database of Weed Plants in the European Part of Russia

Weeds are plants that, although not specially cultivated, grow and often adapt to growing in arable lands. They form an ecological variant of flora, as a historically-formed set of species growing on cultivated soils. For the rational use of the chemical and biological crop protection products and to produce safe and high-quality food, up-to-date data on the floristic diversity of weeds and the patterns of its geographical change are required. The need for a weeds' database arises that allows many specialists to work together independently. However, the great value of any database lies not in its existence, but in the accumulation of data that can be used to analyse the factors affecting the species diversity of weeds. New information A dataset of weed species diversity and their distribution in the European part of Russia, based on the results of the authors' own research from 1999 to 2019, has been created. The dataset includes 24,284 observations of occurrences of weed plants, which were obtained on the basis of 2,049 relevés of segetal plant communities in seven regions of the European part of Russia. In total, the dataset includes information about 329 species of vascular plants growing in 65 farmlands: cereals, spring and winter crops, industrial crops, row crops and perennial grasses (Tretyakova et al. 2020). © Tretyakova A et al.

МОНИТОРИНГ РАЗВИТИЯ ЭРОЗИОННЫХ ПРОЦЕССОВ С ИСПОЛЬЗОВАНИЕМ АРХИВНЫХ ДАННЫХ ДИСТАНЦИОННОГО ЗОНДИРОВАНИЯ ЗЕМЛИ

The goal of the research is to develop components of the method aimed at output of information on relief-forming processes from archival and current remote sensing (RS) data with the use of the latest data-processing technologies, including photogrammetry and geoinformation systems (GIS). The proposed components of the methods are highly informative and economically effective. The object under study is located at the border of two active tectonic structures, the South Tatar arch and Melekesskian depression in the south-eastern part of the East European platform (Fig. 1). Based on the study results, it is confirmed that neotectonic movements in the area under study and its recent geodynamical setting are directly related (Fig. 5). It is demonstrated that the morphometric method can be efficiently applied to predict zones of high geodynamic activity and to determine locations of such zones.   Целью исследований являлась разработка элементов методики извлечения информации о рельефообразующих процессах из архивных и современных данных дистанционного зондирования (ДЗ) с использованием новейших технологий обработки данных ДЗ, в том числе фотограмметрии и геоинформационных систем (ГИС). Показана высокая информативность и экономическая выгода предложенных элементов методики. Объект исследования расположен на юго-востоке Восточно-Европейской платформы на границе двух активных тектонических структур – Южно-Татарского свода и Мелекесской впадины (рис. 1). Результаты исследования подтверждают существование непосредственной связи между неотектоническими движениями и современной геодинамической обстановкой недр исследуемой территорий (рис. 5). В статье показана информативность морфометрического метода для прогнозирования и локализации зон высокой геодинамической активности.

Сегетальная флора некоторых регионов России: характеристика таксономической структуры

The authors' data on the weed species composition in 8 geographic regions of the Russian Federation were laid at the basis of this survey. The segetal flora comprised weeds of cereals, root crops, and perennial grasses. The composition and taxonomic structure of weed species were analyzed. The total number of weedy plants encompassed 686 plant species. The level of regional weed species diversity was positively related to the area planted. Altai Territory, Udmurtia, and Rostov Province had the greatest weed species diversity, with more than 300 species, while Vologda Province had the lowest diversity (193 species). Most species-rich plant families (Asteraceae Dumort., Poaceae Barnhart, Fabaceae Lindl., Brassicaceae Burnet), genera (Potentila L., Artemisia L., Veronica L., Chenopodium L., Silene L., Trifolium L.), their subsequences, contributions of single-species families (17-39%) and genera (57-74%) were relatively stable systematic structure indicators. Only 18% of the species were common for all the regions. In each region there were region-specific groups of species. Weed species compositions in geographically close regions - the European part of Russia and the Urals - showed the greatest similarity. As for geographically distant regions (Altai Territory and Rostov Province), their weedy species compositions were distant and contained large groups of region-specific species. © 2020 All-Russian Institute of Plant Genetic Resources -Federal Research Center.
