Report is dedicated to aspects of conceiving the number of scientific magazine Acta Montanistica Slovaca, which purpose was to publish specific key reports from the sixth year of international science conference RESpect 2011. The main aspect in the decision process was to cover the conference agenda, complexity of the global problematic understanding, the subject of examination actuality and the results achievement level. The choice at the same time points on the technological, evaluative, environmental, economical and application aspects of the RES usage, with accent on the Middle Europe region conditions.


Effective usage of people's knowledge, abilities and creativity of people is becoming the key for successful performance in competitive environment of the global economy. Creation of a new discipline - the knowledge management is a reaction to this trend. It includes all progress trends of the recent years and furthermore, it tries to develop a systematic method how to identify, obtain, maintain, and use the intellectual capital. Nowadays, nobody doubts that success of every company on the global market in great extent, depends on how fast it can adjust to quick changes of the business environment. This is also one of the reasons why human capital is becoming a crucial and more valuable factor. Currently, during the era of globalization, the changes are extremely fast therefore it is necessary that companies to reassess instruments and procedures that have been used so far. A proper way is to activate the whole system, think about organizational development and through that change acquire such a system that will be suitable for rapid change in business.

This report is concerned with comparison of amount of power produced by photovoltaic power-station determined before construction by simulation of the given system with actually measured values during the full operation of the power-station. Our objective was to compare and evaluate the results of prediction against actual situation. The solution result is the justification of deviations measured.

The use of renewable sources in the production of electricity and heat is currently rather common practice than something unusual. Nevertheless, while projecting such a source of energy, it is necessary to take into account certain particularities, risks as well as possibilities. With the production and usage of biogas it is the use of local energy and working sources, which has a positive impact on the development of the region. In this article, technical and economic operation parameters of the biogas plant in Rozhanovce are analysed.


Dynamic stall, caused by flow separation, will take place on any profile or other surfaces that are exposed to time-dependent motion in the flow, such as change in angle of attack, wing flapping respectively or another vertical movement. The study comparer results of simulations of flow around airfoil FX 63-137.
