The article is devoted to problems of wind energy. Data growth rate of the installed capacity of wind power plants in the world are shown. The authors analyzed the technical and economic performance of wind power systems ...

Experimental investigations of a flat plate heat transfer in the presence of transition induced by wakes after still and hesitating cylinder were carried out. Analysis of distributions of local heat transfer coefficients, ...

Au nanoparticles were obtained gold target ablation in ethanol second harmonic of solid state laser 215 LQ. The concentration of nanoparticles (NPs) Au was determined to change the target weight before and after ablation ...

Starting from the middle of nineties of XX a new phenomenon became the focus of physicists’ interest – lightning electric discharge in the middle atmosphere at attitudes from 20 to 100 kilometers which are above the absolute ...

The theory of the rotation angle of the plane of polarization in dielectric media has been considered. In paper the dissipative model resonance Faraday effect in dielectric multilayer nanostructures is proposed. Found ...

It is discussed the possible mechanism of photoluminescence of such objects as carbon quantum dots, layers of amorphous hydrogenated carbon, and the natural biopolymer – native collagen. Recently in some researches were ...

This article proves the relevance of the roof fall risk assessment. It bases both in terms of predicting the possibility of their reuse and keeping the coal pillars stability, and the risk of the origin of closed unventilated ...

One of the most important problems in solid state physics is searching new patterns in the performance of the physical characteristics of metals in the external radiation on them. This research deals characteristics of ...
