Brick Dust Arising During Grinding of Burnt Brickwork and Possibilities of its Utilization
Kocmánek, Tomáš ; Sokolář, Radomír (referee) ; Nevřivová, Lenka (advisor)
The diploma thesis focuses on the brick dust arising during grinding of burnt brickwork and the possibilities of its utilization. In the theoretical part origin and basic properties of brick dust is described. Some published results of research on the potential utilization of brick dust in various industries are presented here. Also proposal of utilization of brick dust in the ceramic industry is presented. In the practical part two ceramic raw materials and the two brick dust with different granulometry arising during grinding of burnt brickwork (made from these two ceramic raw materials) were selected. The effect of the addition of brick dust to the ceramic raw materials on the physical - mechanical properties of ceramic body after sintering was investigated.

Utilization of biomas in power plants in Czech Republic
Červinka, Petr ; Mastný, Petr (referee) ; Macháček, Jan (advisor)
The main idea of this project is get to know a distribution of biomass .We will serve out biomass acording to its types and using of it, we are going to compare biomass between the Czech republic and Europian Union. In this project we will inform you about a technology of burning with the fosill cooler.We will write about energic and economic classification too. Actual europian trend faces to more frequently using of a renewable recources energy, where the biomass is the most important part.

Thermophilic microorganisms
Sůkalová, Kateřina ; Vránová, Dana (referee) ; Babák, Libor (advisor)
This bachelor’s thesis is focused on distribution thermophilic species from among microorganisms, characteristic important genera, in which these microorganisms we can find and detailed description choice species. There is described origin of thermal environment and locations of habitation thermophilic microorganisms with intention on geothermal areas, where is found the biggest number of these species. In consequence of thermal stability of enzymes these microorganisms are used in food industry, in waste treatment, in medicine and for their production of thermostabile enzymes.

Possibilities of utilizing waste from the production of cement-bonded particleboards in building materials
Bartoň, Andrej ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
This bachelor thesis deals with possible applications of waste created during cement-bonded particleboard in building materials production. The theoretical part of the thesis analyzes the individual components and processes in the production of cement-bonded particleboard, production processes during which the waste is produced, and the form and quantity the waste can be found in. The theoretical part focuses on the treatment of the various waste forms and their further use in modified or untreated form. In the practical part, the influence of the binder parts substitution on the cement matrix properties is verified. Fine loose waste from the cement-bonded particleboard was used for the sample production.

Analysis of Sharing Networks
Blažek, Libor ; Mašek, Pavel (referee) ; Horváth, Tomáš (advisor)
The aim of the thesis is the design and implementation of the protocol in OPNET Modeler. In this work will be developed all the elements have been used no default settings. In the first chapters, making simulation are defined packets. Another chapter consists of a block diagram of workstations, which are assigned to function blocks. The central process is created by the process model, also for the router. The individual elements are inserted into a variety of elements and subsequently used in the simulation. Connection is a new service that has been defined separately. One of the simulations will be created on a smaller scale and the other on a global scale with more features.

Sewage sludge - the present and the future
Žerava, Zdeněk ; Houdková, Lucie (referee) ; Boráň, Jaroslav (advisor)
Possibilities of sewage sludge utilization are synoptically described in this bachelor thesis. Main types of sludge utilization in Czech Republic are mentioned as well. This work is focused especially on factors influencing the choice of methods of sludge disposing and on comparison of sludge disposing in Czech Republic and another EU countries.

Influence of humidity changes to properties of building materials with organic filler
Vasas, Silvestr ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
The bachelor's thesis deals with the issue of dimensional changes of building materials containing organic filler, in connection with changes in the humidity of the environment in which the material is located. Searches of knowledge, especially from the scientific literature showed a significant effect of moisture on volume and weight changes of both wood itself and wood of cement composites. In this respect, the treatment of wood (thermal, chemical, etc.) ort he surface treatment of the final wood of the cement composite (coating systém, impregnation, etc.) is essential to reduce the rate of change due to ambient humidity. Experimental laboratory assessment of dimensional and mass changes proved compliance with theoretical knowledge and extended them by specifying the effect on individual dimensions. The different behavior of cement-bonded particleboards in terms of their hygroskopicity was demonstrated on the changes of the boards surface threatment with the coating system and on the boards without surface threatment.

Use of family house rainwater for irrigation and soaking
Sirůčková, Renáta ; Kameníčková, Ivana (referee) ; Hyánková, Eva (advisor)
This bachelor thesis is focused on problems of rainwater and their use. The thesis is divided on two parts, theoretical and practical. The first part of the thesis deals with the general distribution of rainwater, from the creation of individual precipitation, their composition and quality, up to their surface runoff. Further, the individual possibilities of their cleaning and subsequent accumulation and soaking are analyzed. Part of the work is also the use of rainwater from the household to the garden. In the second part the specific location for the use of rainwater around a family house is solved. The specific location is situated in the village Voleč in the Pardubice Region. Here is a complete solution accumulation of rainwater, irrigation and soaking.

Extremophilic microorganisms
Procházková, Lenka ; Vítová, Eva (referee) ; Babák, Libor (advisor)
This bachelor’s thesis deals with the extremophilic microorganisms. There is described extreme environment in which these microorganisms occur, as well as several structural and chemical adaptations to the environment. In most cases, adaptation to extreme environment requires changes in the composition of membrane lipids, nucleic acids and proteins. Enzymes with stability in extreme environment are used in chemical, food, pharmaceutical and textile industry. There is also mentioned the application of extremophiles in the biodegradation of organic materials. This bachelor’s thesis is mainly focused on hyperthermophilic microorganisms, which have been most researched.
