The purpose of the study is to examine the impact of the covid 19 coronavirus crisis on the oil industry system by analyzing the reports of oil companies on interim revenues and expenditures, as well as their future plans for programs to improve their condition after the crisis. The main countries chosen for the study were the United States, Russia, China, Mexico, Italy, Norway, great Britain and Spain. The largest companies in each of these countries were selected for data analysis. The analysis revealed the loss...

The overlapping of the Yenisey River by Dam of Krasnoyarsk hydroelectric power station noticeably altered abiotic conditions of habitats of river ichthyokoinos in the zone of an artificial pond - Krasnoyarsk reservoir. Its mode of operation for the past 50 years is defined in foremost tasks of hydropower and practically does not take into account the criteria of conservation of homeostasis of aquatic ecosystem and fisheries interests. Change of rheofeeling complex on limnofeeling in the process of forming reservoi...

The article is devoted to the study of the formation of industrial clusters on the territory of the Southern Federal District (SFD) of the Russian Federation, as well as the rationale for the feasibility of this management activity, taking into account the industrial-industrial complex formed in the macroregion, represented in the sectors of the agro-industrial complex, chemistry and petrochemistry, metallurgy and engineering, food industry, etc. A statistical analysis of the main indicators of the development of ...

A precise line that can be called a coastline cannot be determined due to the coastline paradox. However in general terms, coastline or seashore is an area where land meets the sea or ocean, or a line that forms the boundary between the land and the ocean or a lake. In port areas, where port berth is a stable structure, determining the coastline is easy given that the coast structure is defined by vertical bank. Other examples of stable port structures include: slipways, cliffs and solid borders between water and ...

Accuracy requirements in hydrographic surveys inspire drive to seek improvement in measurement devices and systems used to, amongst others, determine coordinates of the position of sounding vessel and ideally sea bed reflection points of acoustic wave. Limitation to requirements included in international rules, especially included within IHO S-44, does not fulfil expectations of principals. It is however possible to execute using modern measurement (geodesy) devices and systems. Measurements and soundings historic...

This article is devoted to the study of the main stages of modernization of the sphere of housing and communal services in the Russian economy, the main trends in the modernization of the country's economy as a whole and, in particular, the sphere of housing and communal services. The structure of modernization of Russian scientists is divided into three sectors. The first one is export, which is competitive in nature, as it includes the production of materials from oil, oil products and natural gas that prevail i...

The work is devoted to the search for approaches to reducing the ecological risks of the urban population with the goal of preserving human health. It is assumed that a well-formed urban ecological framework will most compensate for negative environmental factors affecting human health. A methodology is proposed for constructing an urban ecological framework based on predicting the level of environmental risks in an industrial city. At the same time, the link between the quality of the urban environment and human ...

The problem of upper atmosphere and lower ionosphere response to anthropogenic greenhouse gases global increase is considered on the basis of the Institute of Numerical Mathematics of the Russian Academy of Sciences coupled atmosphere-ionosphere general circulation model (for altitudes 0-90 km). This model is a high-level numerically complex three-dimensional atmospheric circulation model (AGCM) and a part of the INM RAS climate model (INMCM), which has been developed in INM for more than 40 years and has taken pa...

As numerous studies show, changes in the environment at the end of the 20th century have become global ones. This means that the buffer capacity of the Earth, and the planetary boundaries have been subjected to a massive impact of the different human activities for several decades. Achievement of the Sustainable Development Goals, adopted by the UN, is becoming more difficult to fulfill. Chemical pollution directly or indirectly affects the quality of natural resources, including water. Providing the population wi...
