Využitie kombinovaného systému na báze pyrolýzy biomasy, resp. triedeného komunálneho odpadu, v kombinácii s čistením exhalátov za pomoci elektrického výboja, poskytuje zaujímavú možnosť znižovania skleníkotvorného CO2 a súčasne rozvoja niektorých foriem obnoviteľných zdrojov energie. Testovaný pilotný systém z hľadiska veľkosti zodpovedá približne potrebám bežne stavaných rodinných domov., Marcela Morvová., and Obsahuje bibliografii
Pointfree formulas for three kinds of separating points for closed sets by maps are given. These formulas allow controlling the amount of factors of the target product space so that it does not exceed the weight of the embeddable space. In literature, the question of how many factors of the target product are needed for the embedding has only been considered for specific spaces. Our approach is algebraic in character and can thus be viewed as a contribution to Kuratowski's topological calculus.
The remarkable progress in laser technology leads also to a development of techniques of time-resolved optical spectroscopy. The ultrafast laser spectroscopy in the visible spectral region can be now used for investigation of rapid processes with the time resolution of about 10 fs. This paper reviews the experimental background and typical techniques of ultrafast laser spectroscopy. The potentional of ultrafast spectrocopy is illustrated with the results obtained by authors in the field of ultrafast relaxation processes in semiconductors and semiconductor nanostructures., Petr Malý, Petr Němec, František Trojánek., and Obsahuje bibliografii
