This article discusses the questions of agroecology, its role and significance in the modern economy. It emphasizes the impact of agroecology on food production, country food security ensuring, as well as contribution to the sustainable agriculture. The authors also accentuate the relationship of agroecology with sectoral clusters, which are one of the modern forms of economic activity organization in agro-industrial sphere of Russian Federation economy. The article describes preconditions of the clusters formatio...

This paper presents an assessment of power generation losses of a hydropower plant (HPP) due to an imposed reservoir management plan and comparisons in terms of monetary value with the existing management plan but with an eutrophic reservoir. The study case is represented by Gole?ti reservoir, which is a shallow reservoir in Romania, and the associated HPP. Gole?ti reservoir is an artificial lake of medium size, which has a 55пїЅ106 m3 volume and a maximum depth of 32 m. Its use is complex: it allows flood control...

The study was conducted to explore the phyto- and zooplankton composition and abundance in ponds located at Komsomolsk tailing dump, Kuznetski Alatau, Russia. Four ponds and one lake were sampled in detail: the pond in the northern part of the tailing dump (sample KP-1), the watered trench near the pond (sample KP-8), the red pond formed on the shifted Berikul tailings (sample KP-9), the settling pond (sample KP-10) and the natural lake Bolshoy Berchikul (sample KP-11) located 10 km away from the tailing dump as t...

The modern society is focused on the main recommendations of the TEEB - The Economics of Ecosystems and Biodiversity. One of the document directions is "Business can save biodiversity and improve the exploitation of ecosystems". The task is to strengthen those economic development strategies that are environmentally sound, socially just and profitable for business. Such measures are an integral part of the resources rational use policy in modern industrial enterprise. The object of this study was the process of pr...

The purpose of the study was to develop an electrochemical method for detection of lead at low level of contamination in water samples using a carbon glassy electrode modified with the functionalized azulene: (2E)-2-(azulen-1-ylmethylidene) hydrazine carbothioamide (L) as a complexing polymer film. The modified electrodes were prepared in L solutions (1mM) in acetonitrile (CH3CN) containing tetra n-butyl ammonium perchlorate (0.1 M TBAP) as supporting electrolyte. The analyses were performed on Autolab PGSTAT 12 P...

The buildings contribute largely to emissions of greenhouse gases. By bringing about changes in this sector, we can achieve significant reductions in these emissions, with an important role in achieving the EU objectives on Near Zero Energy Building (NZEB). According to the European Council, the energy consumption of buildings represents 40% of total energy consumption, contributes to 36% of the emission of greenhouse gases. Worldwide population growth, especially in urban areas, causes an increased consumption of...

Nowadays the renewable sources of energy are gaining more and more in importance to meet the society requirements of energy in a sustainable way. Biomass is among the renewable sources of energy which is known and used since ancient times and it is of great importance for present as well as for the future. One source of biomass are agricultural crops through their residues but also as agricultural crops specially designed to produce biomass and known as energy crops. Although the biomass was traditionally used to ...

Innovative aerobic granular sludge (AGS) technology has proved its ability to remove organic pollutants and nutrients from wastewater treatment at the same efficiency, but at a lower costs than conventional biological process. This technology has been successfully applied in sequencing batch reactor (SBR) configuration. An experimental model bioreactor was designed for adapting the AGS technology to continuous flow conditions. This paper presents numerical results for hydrodynamics and air dispersion into bioreact...

This article proposes a software tool, based on artificial intelligence technics, to grid operators and energy companies, to optimize the power system. Precisely, it uses pattern recognition capabilities of neural networks, in order to enable a higher share of renewable energy to consumers. The applied analysis on PV power and other related electrical grid data, such as smart energy meter readings, are based on pattern recognition technics. The neural networks used for this approach will identify days of the week ...

The brownfields regeneration is very expensive process however it has important socio-economic effects. Many brownfields were revitalized also in the Southeast Cohesion Region in the Czech Republic, which is selected as the studied area. The research sample contents data from 28 CBA projects located in this area. The aim of this paper is to evaluate contribution of socio-economic effects to total efficiency of these projects based on benefit-cost ratio (BCR). The paper also deals with the classification of brownfi...

The analytical review was conducted of modern scientific-technical, regulatory, and methodological literature in the area of existing experience in assessing the sustainability of coastal systems and coastal infrastructure, as applied to marine spatial planning. The analysis showed that currently there is no uniform approach to the assessment of sustainability of coastal systems and coastal infrastructure, as well as various impacts on the environment. The existing global and regional concepts of assessment of coa...

Urbanization is a global process most widely spread in the second half of the 20th century. In 2009, the urban population was equal to the size of the rural population and its importance is growing now. City conditions are so specific that at present some scientists note the excistance of processes that form a new adaptive type of man at the phenotypic level пїЅ urban type in addition to already existing high-mountainous, arctic, temperate latitudes and tropical types. The main groups of factors that affect the st...

Preservation and liquidation of selected mines is a serious problem of mineral resources sector. It is acknowledged that пїЅdisturbedпїЅ lands lose their value due to such activity, and land reclamation appears to be the most efficient solution for this problem. Not all the sites of mines are subject to unconditional liquidation given the academic and historic-cultural potential what allows considering these territories in a different capacity. The practice of industrial space revitalization by museumification and...

Tatarstan is one of the richest regions of Russia in terms of oil deposits. There are more than 100 oilfields with more than 3 000 000 000 tons of oil extracted up to day. The main deposits concentrated in in Devonian and Carbonic deposits, controlled by different genesis traps. Tatarstan is divided into 3 parts by the main rivers пїЅ Volga and Kama. The main oil deposits concentrated in the South-East part (South Tatar arc), while there are almost no oil in the North (North Tatar arc). To understand the structure...
