The modern life and industrialization with their great impact and large scale of influence generates a colossal amount of waste products. Not only that they have huge physical volume but they also cause many short and long term effects on the nature, human way of life and all processes on the planet. The waste products' concentration in specific zones leads to conditions which makes them uninhabitable. The construction of landfills for industrial solid waste follows the modern requirements for disposing, encapsula...

The purpose of this study was to create maps using a set of GIS technologies that pres...

Currently, the trend is to increase the demand for high-rise buildings roofs that would serve as a social space or as a green roof. This trend is also confirmed by the fact that due to the lack of space in the city, the buildings are being built up even higher and the social space needs to be created as a part of them. The main idea of this article was to analyze the different shapes of the roofs using computational fluid dynamics (CFD) simulation software and to demonstrate the suitability of their use.

Climate change is one of the greatest global challenges of the 21st century and has manifested itself over the past few decades through extreme weather conditions, rising sea levels, and through oscillating temperatures and precipitation regimes. While temperature and precipitation data are available on a daily basis, precipitation data are more susceptible to measurement errors, have a lower spatial representation and are asymmetrically distributed. While previous studies on precipitation changes have predominant...

In this paper we will describe a novel approach for forest management that includes remote sensing based monitoring, simulation and planning. When we think about sustainable forest management, it is important to know the vital facts about the forest, especially the annual increment of the timber volume for each forestry unit. A terrestrial census could deliver the required information, but it is too expensive to be carried out frequently. The alternative is a census based on remote sensing data. In this area we ob...

Classic models of fault related folding frequently fails to describe complicated geological structures. The combination of tectonic modelling techniques can be used to reproduce observed geometry of folds. Indirect information contained in geophysical data can provide a good quality check for proposed tectonic models. The Draganowa Anticline is the westernmost part of the Draganowa-Iwonicz Fold. This structure is characterized by existence of very steeply dipping limbs in shallow zone which turns into gentle antic...

Every infrastructure development project encroaches upon habitable space and the natural environment. Local communities? doubts concerning construction projects cannot be effectively dispersed without public debate and the dissemination of reliable information. This is a very important consideration because infrastructure development is a public service, and construction takes place on land that constitutes private property at the planning stage. Public opposition can halt construction, and developers who disregar...

The paper concerns the pores systems characterization of the Miocene mudstone samples provided by mercury injection capillary pressure (MICP) method. This analysis is the progressive intrusion of mercury into a porous structure under stringently controlled pressure. Since mercury does not wet most substances and does not spontaneously penetrate pores by capillary action, it must be forced into the pores by the application of external pressure. The required equilibrated pressure is inversely proportional to the siz...

The current demand for energy production in dissipated systems and the related need for miniaturization of power machines require the use of appropriate technical solutions. Increasingly, power generation microsystems are used to produce electricity that functions in hermetic circuits (e.g. ORC - Organic Rankine Cycle). Rotors of such type of machinery, in order to generate the expected amount of energy, must rotate at speeds up to 100,000 rpm. Rotational speeds of this order represent significant problems in the ...

Speciation of heavy metals in bottom sediments defines their ecotoxicity and mobility and therefore needs to be studied thoroughly. Usually single and sequential extraction techniques are used to determine water-soluble, exchangeable, specifically sorbed and carbonates, bound to organic matter, bound to Fe and Mn hydroxides and residual forms. Bottom sediments of the Vyshnevolotsky reservoir (the Upper Volga, the Central region of Russia) were chosen for the research. Lithological and mineral composition of sample...
