We aimed at identifying the microbial response and associated release of CO2 and CH4 in/from thawing soil that has been permanently frozen. For that we performed an in situ field-based incubation experiment in a rim of ice-wedge polygon on Samoylov island, Lena Delta, Russia (72пїЅ22пїЅN, 126пїЅ28пїЅE). Frozen "buried' organic matter were taken from eroded Lena river bank and transferred to the soil surface in a rim of ice-wedge polygon. The principle includes that formerly frozen soil is moved to the active layer...

One of the general problems of all lines of research is the exhibition of various micro- and macroscopic effects. Considering complexity and heterogeneity of oil composition oil systems can be put down for as complex systems. Research related to the in-depth studying of the various complexity level oil systems chemical composition are highly topical for establishing causes of complications, arising in various processes. For the last decades, stability studies are developing intensively. The emphasis is upon method...

Increasing competition in the domestic and global markets causes companies to be more and more active in taking steps to obtain an advantage over competitors. The area, which is particularly important in building this advantage, is knowledge. Knowledge is the basic resource for every company, which if used properly, ensures development, growth and economic success. It very often happens that the companies are not fully aware of the knowledge potential they possess. Therefore, it is justified to take activities tha...

The aim of the research is to return the disturbed lands of mining landscapes to the biosphere foundation in the light of modern knowledge of the role of Earth's soil shell in maintaining the stable state of the biosphere. The methodology has been substantiated and the technology of restoration of disturbed lands (ecological restoration) has been developed in accordance with the concept of natural soil-formation, which is based on the principle of self-organization of natural systems. The data of the long-term mon...

Economic gentrification means bringing more material value to a specific area by increasing its attractiveness and upgrading it. In the case of small deposits with permanently discontinued exploitation (only historical significance) and scarce resources, it is more socially and economically efficient to withdraw the deposits from the balance of mineral resources and enable changes in the management of the area. As a result, it is more possible to introduce different post mining deposit developments, such as using ...

At present, there is a lot of interest in finding new energy sources because energy consumption is much above energy production. Geo-thermal energy is part of the category of renewable energies and a non-polluting green energy. Humans have used hot water springs from times immemorial for different purposes. Statistics show that Romania has an outstanding potential in geo-thermal water resources: it ranks third in Europe after Greece and Italy. However, geo-thermal waters are underestimated. The authors of this pap...

Gullies (ravines) have been identified on an area of 33 km2 (11.79% of the depression). Morphometric assessment of the conditions of gullies spreading wa...

Periodic thermal processes and periodic temperature fields are well represented in nature and technology. In nature, they occur largely due to periodic processes such as one year Earth's orbital motion, day and night cycle of the Earth's rotation around its own axis, etc. With conductive heat transfer mechanism daily temperature fluctuations almost damp in a layer thickness of about 1 m, annual temperatures do it in layer of 18 to 21 m thick. In the case where periodic heating by the Sun coincides with the mass tr...

The geophysical surveys methods have not been extensively used in gold exploration in Northern Portugal. This is based on the fact that most mineralized zones contain low and erratic sulphide contents. In this work were tested three different types of geophysical surveys combined with geochemical surveys, in order to define anomalies that are closely correlated with the locations of known mineralized zones. The aim of the work is to study some gold deposits in Northern Portugal (Lagoa Negra and Castromil) with the...

Protection of groundwater against pollution is an important part of maintaining sustainable development. In addition to the impact of the anthropogenic activity, groundwater resources may be exposed to many different kinds of pollution e.g. during floods. In such areas, knowledge about spreading mechanism of pollutants can contribute to choose appropriate preventive protection e.g. hydrogeological, hydraulic, geotechnical or other different measures. The presented problem can be solved by finite element method in ...

Disposal of increasing waste production in mining is currently a serious problem of civilization. The most common way to dispose of mining waste is storing them on impoundments. The hydraulic transport is advantageous from the standpoint of service and perhaps economy too, but the geotechnical properties of the resulting sediment are poor especially when saturated. For the design and construction of safe dumps with minimum impact on the environment the knowledge of the geotechnical properties of sedimented mining ...

Stage of construction works is responsible for the most part of risks, emerging during construction project. Violation of technologies of construction works, unsatisfactory quality of construction materials leads to additional costs of an amount equal to the cost of alteration of works. Each violation on the construction site on itself leads to insignificant damage, however, their frequency and complication at further stages entails a much larger aggregate damage. ThatпїЅs why qualified construction management per...

Hungary is well known for its geothermal potential, used mostly for spas. Where geothermal is used for energy production, it is mostly in the form of a direct heat supply for heating housing projects and businesses. Currently, no geothermal power-plant is operating in Hungary. Neither is the ground-source heat-pump market very strong, maybe because of HungaryпїЅs depressed economy, which still hasnпїЅt recovered from the global recession. All the same, a few large-scale projects are underway. Their realization is ...

A concept of Geographical Information System (GIS) refers to a special system developed to collect, store, analyse and visualise geographical spatial data and related attribute data.
