Methanotrophic bacteria are unique group of microorganisms structurally and functionally adapted to use methane as a source of carbon, which is of great interest due to their ability to oxidize atmospheric methane. Methanotrophs are known to associate with mosses, which provide bacteria by habitat and protection. Methanotrophic bacteria provide mosses with carbon dioxide resulting of methane oxidation, whose content in moss tissues can reach 32%. We studied mosses and lichens sampled in Eastern Siberia permafrost ...

The current climate change, demographic problems and unequal territorial and seasonal distribution of fresh water supplies lead to a sharp expansion of the reservoir network. Subsequently, the negatives associated with the process are increasing: flooding of lands and infrastructure, impacts on climate, change of underground water regime, activation of landslide processes and rising population security risks. During designing of water reservoirs, they were not investigated and taken into consideration. The rationa...

The active development of large cities leads to increase of wastes. And as a result, a system of interrelated problems was formed: 1) The negative impact of municipal solid waste (MSW) landfills on the population and the environment; 2) The irrational use of land adjacent to metropolises; 3) The lack of modern facilities. In Russia the MSW landfills for a long time will be used for disposal of solid wastes residues. To date, 93% of generated wastes is placed on landfills. The main objective is to reduce the number...

Due to pressures to conserve energy, many buildings have in recent times been retrofitted with additional insulation. This has resulted in the appearance of microorganisms on the surfaces of building facades more frequently than before. This does not mean, however, that these microorganisms are not also found on uninsulated buildings. In earlier years, the facades of the apartment buildings were not aesthetically distinctive, often using colors such as gray, beige, and the like. Microorganisms may not have been as...

Climatic features and biogeochemical specificity of Russia?s north have a great impact on public health. It is believed that the cumulative effect of these factors is not fully compensated by social or other methods of protection.

Mineral phases - mainly oxyhydroxides of Fe, Al and Mn - are transported by surface waters and are conseq...

Directional couplers can divide the input power between its outputs in different proportions. This is due to the ratio of wave resistances between two pairs of quarter-wave segments. Due to the fact that at frequencies of 2 GHz and lower couplers are also actively used, it is necessary to take care that their dimensions satisfy the radio system where they will be installed. Due to the fact that it is not always possible was investigated miniaturization as an opportunity to reduce the area occupied by the branch wh...

The municipal solid waste landfill in Tychy, southern Poland consists of three sites, the old one, closed in 1994, and two others still being in use. The old part of the landfill has neither any bottom liner nor any leachate collection and treatment system. Moreover, the bottom of the closed site in the northern part is continuously above the groundwater table, therefore, pollution can easily release into groundwater causing deterioration of groundwater quality and the nearby river nearby. In order to assess the i...
