Mining is a strongly impacting anthropogenic activity, affecting to a greater or lesser extent the natural components. Thus, it is consensual that should be established a common practice that aims at the recovery of degraded mine sites. Otherwise, environmental balances can be irreversibly destroyed, with serious negative consequences for surrounding ecosystems, including humans. Therefore, the environmental reclamation of a mine site can be defined as the general process of repairing disturbed, damaged, degraded,...

The skin is covered with a hydrolipid film that, depending on the area of the body, comprises secretions from sebaceous glands and from apocrine and eccrine sweat glands. Decomposition products from corneocytes and cornification (cellular debris and stratum corneum lipids) in the process of being shed are also present. This film provides a natural defense against pathogenic organisms but also attracts dirt and pollutants from the environment. Thus, periodic cleansing to remove debris, dirt, and odor is essential t...

The urban sprawl has an important impact on the socio-economic evolution of a city as well as on its environment. A defining characteristic of the western European capitalist city, the urban sprawl was not often observed in the urban areas of the Eastern Europe. However, it has become more and more relevant after the 90s because the transition to the post-socialist era determined an increasing development of the sub-urban areas of the cities from the ex-communist bloc. This paper studies the case of the post-socia...

Coal mining causes undesirable terrain subsidence due to caving in of the overlying rocks into the already excavated space. Subsidence deforms the terrain, damages structures on the surface and water flows, which results in the formation of inaccessible wetlands and swamps, and these areas need to be reclaimed. The problem of large flooded areas as a result of mining activities also concerns an area known as ?Kozinec?, which is located between Karvin? and Doubrava in the Czech Republic. That territory has long bee...

Pile driving technology remains the most widespread method in Arkhangelsk where the presence of soft soils is an engineering-geological feature. There are situations when pile driving by hammer can be safe for existing buildings. Using two hammers allows to accelerate foundation works but it can damage the adjoining buildings. The monitoring of pile driving by two diesel impact hammers was carried out at one of the sites in the city. Vibration parameters were measured with triaxial accelerometer CMG-5 with continu...

Social housing management is an area of asset management within local government which is strongly dependent on legal and socio-economic system as well as public housing policy. In many countries housing systems are in transition towards privatization, deregulation and decentralization of public tasks. The transformations in institutional and economic context have lead to more market-oriented social housing management. They have not been an isolated process but a part of broader one termed New Public Management (N...

In this paper, the authors discussed one of the Hume-Rothery conditions for occurring substitutional solid solutions in the context of binary relations. The analyzed condition says that substitutional solid solutions may form if the ionic radius of the solute and solvent ions differ by no more than 15%. Because the problem concerns a mathematical connection between two objects, the authors suggested describing this problem using the set-theoretic notion of binary relation. In this context, the possibility of formi...

For the analysis of various characteristics of natural objects distributions cluster analysis, principal component analysis and regression analysis are often used. There is a large number of distributions of the parameters of natural objects (e.g. spectral characteristics of soil), where the function is unknown, and discreteness is not visible, and contrary to the basic properties of described object. The soil cover is continuous in space and has no clear boundaries between spectral characteristics, such as soil l...
