Utilization of by-products from cement-bonded particleboards production in base layers
Dobrovolná, Martina ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
This thesis deals with the use of by–products from the production of cement–bonded particle boards as an alternative raw material for the stabilization of the subsoil or into a ground solid. The theoretical part briefly describes the current status of waste management. A set of alterantive raw materials used to hydraulically cemented mixtures is listed here as well as the recherche of the foreign research is elaborated from this area. The experimental part of the thesis firstly deals with the choice of raw materials and basic recipes. In the advanced stage the laboratory analyses are carried out on the modified formulas. Based on the results of these analyses the posibility of using by–products from the production of cement–bonded boards for the stabilization of the subsoil is evaluated here.

The technology of ceramic filters as a problem of their shaping
Dobrovolná, Martina ; Janíček, Martin (referee) ; Sokolář, Radomír (advisor)
The aim of this bachelor thesis is to evaluate possible production of ceramic filters made by dry pressing and to choose suitable granulate and its optimal moisture proper for this way of production. The theoretical part of the thesis explains the meaning of the usage of ceramic filters in a foundry industry. Further more, the technology of ceramic mixtures production and the technology of ceramic filters production made by wet pressing and dry pressing is drawn near in this thesis. The practical part describes the production process and the testing of experimental samples. The influence of different kinds of ceramic mixtures, their moisture and different modes of burning is compared to physical-mechanical features of ceramic potsherd. The output is to design a material with a set of typical features which would by suitable for dry pressing production.

The issue of punctuation in the teaching of the Czech language at the second grade of primary school
DOBROVOLNÁ, Martina
The bachelor thesis is focused on the issue of punctuation in the teaching of the Czech language at the second grade of primary school. The theoretical part deals with general rules of using punctuation in simple sentence, compound sentence and complex sentence. The second part of theory deals with comparison of interpretation and the type of exercises in chosen contemporary textbooks of Czech language for eighth and ninth grade children. The practical part is about checking a level of achieved knowledge of punctuation at the eighth and ninth grade children.

DOBROVOLNÁ, Martina
My thesis is about traditional celebrating of feasts and holidays during ecclesiastical year. It introduce us art techniques which is connected with these dates. At the start we familiarize us folklore and folk art and it shows us differences between folk art and city art. Next chapter is about ecclesiastical year and about important dates in church. At the next part we can read about time of pubescence, its characteristics and progress what the teenager has to go through, and with the typical behaving and work of these young people. The practical part leads us through the innovative art techniques and introduces us traditions and customs on our villages. We can also read here some facts about celebrating feasts in other parts of Europe and World.
