HUBAČ, Tomáš
The aim of this thesis was to compare several biogas plants in the South and Central Bohemia in several respects. Overall, it was also beneficial to see how these biogas plants solve or not solve the pretreatment of the substrate, as well as the use of ancillary benefits, such as the use of heat or residual digestate. Part of this thesis is a literature search, mapping the possibilities of increasing the efficiency of agricultural biogas plants.

Biomass as a base material for the production of fuels and energy
HUBAČ, Tomáš
Nowadays, with the dwindling fossil fuels there is need to find a new source of energy. One of interesting possibilities is to use biomass. The energy from biomass can be obtained in many ways. There are three main directions. Thermochemical conversion which involves incineration, gasification and pyrolysis. The biochemical conversion which comprises of anaerobic fermentation, aerobic fermentation and alcoholic fermentation. Last option is physical-chemical conversion comprising of esterification. Subsequently gained biofuel is divided into I, II, and III generation according to the method of production and resources. Alternatively derived biofuel equals, and sometimes surpasses the fossil ones. Biofuel has basic division into liquid (bioethanol, bio-oil, etc.), solid (wood pellets, briquettes, etc.) and gases (biogas, etc.). We should mention the need to improve the efficiency of existing technologies and to invent new economical and environment-friendly techniques.

FOREIGN POP MUSIC CONCERTS IN THE CZECH REPUBLIC
Málková, Gabriela ; Srstka, Jiří (advisor) ; Hubač, Tomáš (referee)
Abstract
Organization of concerts with the uninformed observer may seem to be relatively simple productions where the entrepreneur will also appreciate meeting with the music celebrities, unaffordable for the average mortal.
In fact, it is a very risky business, where the loss of organized events are not unusual. That is the perspective visitors know the concerts from. For organizers, however, moment when the singer or band enters the stage, is just the icing on the cake and ending of the long-term effort. What precedes the moment of the applauding crowds?
That should cover my work with the title: FOREIGN POP MUSIC CONCERTS IN THE CZECH REPUBLIC
