Best Available Technologies for Intensive Livestock Production: Analysis of Present State in the Czech Republic
HAVELKA, Zbyněk
The thesis deals with the issue of the use of the best available technologies (BAT) in poultry and pig farms falling under the IPPC regime in the Czech Republic. The thesis presents an overview of the legislative framework of IPPC in the Czech Republic, an overview of the most important BATs. From the point of view of intensive poultry and pig farms, an overview of the number of facilities and their location in the Czech Republic, reported annual ammonia emissions and BAT used by these facilities is presented.

The Usage of Plasma Technologies to Improve the Quality of Feedstuffs
HAVELKA, Zbyněk
The dissertation thesis deals with the problems of the use of plasma technologies in agriculture for the purpose of improving the quality of feedstuffs for agricultural animals. The attention is focused above all on the use of low-temperature gliding arc plasma discharge generated by the atmospheric pressure for the elimination of model fungal pathogens (T. virens) and for the testing of the possibility of the use of plasma for the decreasing of mycotoxin load (DON and D3G). The professional orientation of the dissertation thesis is strongly interdisciplinary with the overlap to the area of the physics of plasma, microbiology, zootechnics and the proposal and construction of technical facilities. With that corresponds also the division of thesis into individual chapters. In the research part, there is a summary of actual pieces of knowledge from the area of fungal microorganisms and mycotoxins produced by these with the view on their presence in feedstuffs. There follows a research of pieces of knowledge of low-temperature plasma and its applications in the food industry and feeding. In the chapter Material and Methodology, the applicated methods of work, employed instruments and biological material are described. The resulting part is, for its clear arrangement, divided into five subchapters ? stating of selected parameters of plasma device, influence of plasma on nutritional parameters, influence of plasma on the model fungus Trichoderma virens and possibilities of the use of plasma discharge for the decreasing of concentration of mycotoxins in feedstuffs. The final part is dedicated to the description of system which enables the treatment of samples in continuous regime. The treatment of mycelial discs by plasma discharge lead to the decrease of germination capacity of spores of fungi, while there was experimentally proven the synergic effect of the influence of individual mechanisms by which the plasma interacts with the surface of biological material. At the same time, there was not observed a more significant change in the composition of feedstuffs, more significant is only the change of humidity of sample. In the laboratory conditions, the decreasing of concentration of mycotoxins spread on laboratory glass was proven. At the samples of feedstuffs contaminated by natural way, it was not successful to reliably provedecreasing of concentration of mycotoxins in a sample as a result of plasma activity.

Cereals treatment by using of GA atmospheric plasma source
HAVELKA, Zbyněk
This thesis contains a brief summary of the theoretical applications of plasma discharges, and a description of the principle Gliding Arc plasma source. The practical part is focused on the research of the influence ofcereal seed treatment using plasma discharge on their nutritional value (dry matter, ash, protein and fiber). In the conclusion of this thesis is evaluation of the whole experiment.

Blended learning course to teach word processing
HAVELKA, Zbyněk
This bachelor thesis deals with the problem of teaching computer science and various approaches to the teaching of the application environment. The work provides a comparison of available textbooks on the issue. Furthermore, in the theoretical part of the bachelor work is design a modern approach to teaching of the application environment. As a practical output of this work is, as its name suggests, the blended learning course to teach word processing, which is designed as a modern approach proposed in the theoretical part of the work. As most have already developed courses designed to teach only one word processor, this course is to teach whatever the word processor. The course includes teaching materials, divided into five chapters. Each chapter also includes a set of problems for practicing the subject.
