The gas hydrate formation is a non-stoichiometric process, which may be affected by a great number of variables, rather than thermodynamic conditions. Several chemical additives were found to act as inhibitors or promoters (or both together under specific situations) for gas hydrate. The most known chemical inhibitor is sodium chloride, whose effects needs to be widely investigated, due to its presence in about 97% of discovered hydrate reservoirs. However, other elements may intervene on the formation process and...

Methanotrophic bacteria are an essential component of Arctic ecosystems in terms of methane emission regulation. They act like a natural sink of methane and are able to oxidize up to 80% of methane emitted from permafrost soils. In Arctic regions, methanotrophy is related to methane oxidizing activity of bacteria, associated with mosses or lichens [1]. This cooperation provides protection and habitat to bacteria, while mosses and lichens obtain CO2 as a carbon source, which emit during methane oxidation as by-prod...

Zooplankton organisms are widely used as indicators of ecosystem changes (Adrian et al., 2009, Nigamatzyanova G., Frolova L., 2017). Both zooplankton and nutrients play an important role in monitoring and assessing water quality by greatly contributing to biological productivity (Vinberg,1960). In the current study, we examined water quality of different types of water bodies of Ob and Erkuta river basins, based on the analysis of zooplankton communities and the concentration of nutrients. 72 species of zooplankto...

Hydropower plants still hold globally the first position among the renewable resources in the production of electricity. They are one of the most environment-friendly way to generate electricity and thus waterpower is considered as a renewable resource with good prospects. A disadvantage of producing electricity from renewable resources is its problematic storage. Nevertheless, the water sources have a way to store electricity by water accumulation in the reservoir. This principle is used especially by the pumped ...

A responsible approach both to the environment and the principles of sustainable development in recent years not only concerns the corporate ecology itself, but it also overlaps into the field of design and construction of buildings. The concept of sustainable construction of buildings, which is based on three main pillars of sustainability, including the quality of the environment, social and cultural aspects as well as economic efficiency, is closely related to it. The main tasks of sustainable construction incl...

On the Lower Danube, including the Romanian-Bulgarian common sector (between chainage km 845.5 to km 375), the width of the fairway is generally sufficient to accommodate multiple ships. However, in low water conditions (below 3000 mc/s) the depths are insufficient to ensure the efficient transport of goods. Very often, vessels sailing in the critical navigation areas (bottlenecks) can only be loaded at half of their capacity. This situation can cause significant losses for river transport operators and lead to la...

By building artificial landscape elements, significant changes occur in the spatial structure of the city. The intensification of the formation of paved surface changes the hydrological characteristics of the area. Impermeable surface prevents the penetration of atmospheric waters into the soil horizon, which causes an increase in the volume of runoff, flood peak, and pollution loads in urban stormwater. As a consequence of this phenomenon, during heavy rains, a critical part of the city may be flooded. To reduce ...
