Effect from used biomass for economic traffic of biogas station
KMOCH, Vít
In this bachelor thesis are processed information and notions, associated with production of biogas and biogas station. Literary review is focused on the process of creation biogas, using biogas, the basic information about biomass and biogas stations, stability of process biogas station and the basic information about digestate. In the practical part of my bachelor thesis I introduced information about farm and biogas station, which is owned including technical solutions and a description of the most important components by biogas stations. Then I was following up with the measuring of the optimal daily feed biomass feedstock, gas potential and economic evaluation of biomass, depending on the quantity of biomass and produced electrical energy.

Proposal for measures to increase the efficiency of biogas station "Agroplyn Mileč - Maňovice s.r.o."
TOMKOVÁ, Michala
The bachelor´s thesis deald in particular with distibution of heat produced in the biogas station in Mileč on Pilsen region. In addition, here describes the factors that affect efficiency of the biogas station, pre treatment of substrates, high quality technology, economic and technical part of heat distribution from a central supply of heat. Based on these findings can improve efficiency of the biogas station. Which will have a positive impact not only the environmnet but also on financial page of the biogas station Mileč.

The influence of selected parameters on the quality of meat products
ROUŠAL, Jiří
This Mater´s Degree Thesis focuses on the sensory analysis of the chosen products of the non-perishable meat products in the dependence on the production technology. Its aim is to compare what kind of the products is prefered by the consuments using the sensory analysis and then statistic evaluation. The theoretical part summarizes the findings of the sensory analysis of the products, it also includes the conditions of the analysis and the statistic evaluation, sense perception in general and the production technology of meat products. In the practical part is described the method and the results of the hedonic test performed. In the thesis were used for evaluation the samples of the non-perishable meat products of the leading Czech producers of non-perishable meat products distributed and available in the shops in the Czech Republic.

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.

Mechanization intensive composting technology
HLAVINKA, Pavel
This bachelor thesis is focused on the intensive compost technology and the biogas production of the biologically decomposable waste. The theoretical part describes the technology of compost production in the tracked piles as well as in the loose areas, followed by the description of the biogas technology and biogas stations with all the related equipment. The biogas is the main product of the anaerobic digestion. Subsequently, we describe the conditions necessary for the biogas production, e.g. the constant temperature, pH, and the nutrients? presence. In the field part of the thesis there we describe the AGRO?Otročín plc. biogas station, as well as the technology hereby in use and its individual parts with the concrete values and figures followed by the basic characteristics of the cogeneration aggregate and the noise level measurements of the technology presented.

Design of technological set of device for production of bioethanol with a yearly capacity up to 500 000 litres.
SLANINKA, Milan
This bachelor thesis deals with the production of bioethanol for the use as fuel. The first theoretical part describes the process of the bioethanol production from the commonly grown cereals, then it focuses on the sources and characteristics of materials that can be used for the bioethanol production, it also follows the legal burden put on such production. The other part of the thesis contains the design of the technological set of devices for the bioethanol production with a given capacity of the yearly production.

Factors influencing quality and nutritive value of grass silages
NOVOTNÝ, Jaroslav
The paper analyzes the factors affecting the quality and nutritive value of wilted grasssilage. Grass silage sample were collected in the operating conditions for the firstmowing. Three groups were formed after 12 samples. The first group was the controlwithout using preservatives. The sekond group were included in the silage treated withbacterial agents. The third group included the bacterial-enzymetreated silage additives. There were no statistically signifiant differences in lactic acid kontent (P < 0.05) andvalues of thedegree of proteolysis (P < 0.05) between the kontrol group without the useof silage additives and the group, which was used for bacterial and bacterial-enzyme additives.

Sensoric assessment of the durable meat product depending on the production technology.
TÁBOR, Rudolf
This diploma thesis deals with sensoric analysis of the selected types of durable meat products depending on the production technology. By sensoric assessment and subsequent statistic analysis, this diploma thesis pursues to compare fermented durable meat products, made without added starting cultures, with fermented durable meat products, made with added starting cultures, and to determine which of these kinds of products are preferred by the evaluators as well as the consumers. The theoretical part of this thesis summarises the conclusions arising from the sensoric analysis of the food, including its conditions and statistical evaluation, sense perception generally and the technology of the production of fermented durable meat products. In the practical part, the applied method and results of the performed twin preference test are described. Samples of the durable meat products of the major domestic producer of the durable meat products, commonly distributed and accessible in the trade network of the Czech Republic, were used for the purpose of evaluation.
