The accelerated evolution of the anthropogenic land use together with the involved dynamics of the land use changes has deepen its environmental impact and increased the population demands. The usage of satellite images became in the last decades a complementary method for obtaining structural information on the urban land use due to major developments in domains such as remote sensing, geographic information systems and photogrammetry. Accurate information on urban built-up area is essential for multiple key area...

If the place hydrogeological conditions are uniform (invariable aquifer transmissivity, no impact of hydrogeological network) then the quarry depression cone and the pumping rate for the quarry draining can be obtained by using analytical methods. The dolomite aquifer at the Iecava district in Latvia included large impervious areas. Due to this fact, appliance of analytical methods cannot give the right depression cone. The local hydrogeological model (HM) was applied for obtaining the depression cone of the dolom...

Based on the analysis of literary and cartographic material, zonal-landscape characteristics of the development of a producing economy and the emergence of the first environmental challenges in the territory of Russia are assessed. The first environmental problems were caused by a change in the climatic conditions of the life of the earliest settlers and by the peculiarities of the emergence and development of their producing economy. The emergence of the first centers of producing economy in the territory of Russ...

To date, certain experience in paleolandscape research has been accumulated in various regions of the country. The research is based on the central principles of classical paleogeography. Large-scale paleolandscape mapping was carried out by the authors on the basis of combined landscape and archaeological studies in the key areas of the forest zone of the European territory of Russia. Paleolandscape mapping is based on the combined use of the results of paleolandscape reconstructions, detailed palynological analy...

Currently, the degradation of the structure of chernozems in agricultural activities is taking place. At the same time, there is a natural diversity of chernozems that are located in different environmental conditions, so the degree of degradation can vary significantly. From these positions, the comparison of the structural-aggregate composition and waterproofness of the structure of arable chernozems, widespread in the Belgorod oblast and the Krasnodar territory, was carried out. The low quality of the structure...

Conceptual models of the decision-making theory under conditions of deep uncertainty formed the basis for an empirical analysis of practical reality deviations from theoretical developments and justification of the need for the formation of appropriate competencies and behavioral patterns among the students of technical universities. The analysis of annual companies' reports in the section of risk assessment and management was carried out. The analysis is based on a text analysis methodology implemented in an open...

The present research (landscape, landscape-historical and landscape-ecological) was carried out to determine the landscape-ecological potential of Moscow for the purpose of territorial planning and with a view to developing proposals for the balanced and effective urban development, for ensuring the comfort of living for the city’s population, and protection of the environment and objects of cultural heritage. The research included: a detailed analysis of the natural, cultural and historical features, an assessmen...

Building of a shopping center was planed in Riga city, Latvia. Unfortunately, the center was located in the former dump site place where the about eight meters thick waste body contained an irregular mixture of oil products, Phenols, Detergents and metals: Copper, Lead and Chromium. It was presumed that these dissolved in groundwater contaminants should enter the nearby lake and dich. It was found out that cleaning of the place was not time and cost effective. It was necessary to reduce the concentration of these ...

The purpose of this study is to develop approaches for the monitoring the environmental and reputational risks of building industry’s companies; to confirm the hypothesis that it is possible to use audited financial and environmental reports as sources for monitoring. The basis of the author's idea is the conceptual approaches of the international standards on auditing and true view tasks, as tools to guarantee the reliability of the results of monitoring environmental indicators in conjunction with key audit issu...

Buildings consume a large quantity of energy owing to their constant operation and long lifespan. Building-energy simulations are an important element of the decision-making process because they allow designers to examine the energy and comfort effects of various building design alternatives. In hot and arid climate conditions, cooling tends to dominate building thermal energy use. Cooling loads can be reduced through the adoption of efficient building envelope materials. This study investigates the optimal thickn...

The electronic historical-geographical atlas of cultural and historical landscapes of ancient waterways is a combination of a traditional atlas and a geographic information system (GIS). The atlas intends to include electronic, accessible via the Internet, integrated maps of historical waterways, interactive three-dimensional models of their most important sections, with identified natural and hydraulic monuments, historical and cultural objects, historic monuments and sites, including descriptions of the topograp...

The aim of this work is to optimize the growth parameters of D. salina by altering nutritional factors, in order to maximize production of antioxidants and lipid fraction by the microalgae strain. For this purpose, the concentrations of different salts in the growth medium were varied. The biomass obtained was analyzed quantitatively and qualitatively in order to determine biomass concentration and bioactive compounds concentrations in respect to the growth medium composition. Pigments were extracted from the drie...

The forests of south-western part of Zemgale Plain in Latvia are characterized by Scots pine (Pinus sylvestris L.) stands on fertile, nutrient rich soils. The existing information about these sites suggests of the calcium carbonate rich loamy sand soils formed by moraine. The Scots pine stands in area of Tervete National Park reach age of 260 years. The oldest and biggest trees reach considerable dimensions – up to 70 cm in diameter and height of 47 m, thus exceeding the country's average indices. These are the ol...

The effectiveness of rhizobia-legume symbiotic interaction is under the genetic control of macro- and microsymbionts. Both symbionts exhibit high level of genome/genome specificity interaction which is reflected by symbiotrophic indices vary significantly. Virulence and plant dry mass increasing are indices widely used in order to reveal well matched rhizobia strain and variety of legume host plant for practice demand. The aim of the research was to study how allelic polymorphism of symbiotically significant genes...

The article deals with the issues of domestic tourism. It is proposed to use the ideas of synergetics to assess the development opportunities of the tourism business in three regions of the Arctic zone of the Russian Federation, taking into account their physical, geographical and economic position. Tourism resources, types of tourism and accommodation facilities were discussed, as well as types of recreational activities in these areas. It is shown that the tourism business is an interdisciplinary science, as it ...

The global problems of the functioning of the economy, industry and energy are among the most important areas of scientific interest and knowledge. Renewable energy sources play a significant role in the global energy sector. The potential applications of these sources are almost limitless, which makes it possible to expand the list of energy resources used. With the economic growth of the forest, woodworking and pulp and paper industries, waste from the wood used in processing-bark and branches, wood chips, scrap...
