Ventilation in the sports facility
Sedlařík, Jakub ; Bernard, Jiří (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with air conditioning sport object. The building is located in Znojmo. The aim was to design three air conditioning equipment for bowling, gym and sanitation. This is the air conditioning and mechanical ventilation. In the first part of the theory is mainly focused on selected objects sports facilities and sports centers microclimate. The theoretical part explain the issue halls air heating, radiant heating and air conditioning, and finally its use. After the theoretical part of the calculation follows that addresses the design of the equipment for each room.

Air gymnasium with facilities
Silbernágl, Petr ; Bernard, Jiří (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with air conditioning gyms. The aim was to design a two to three air conditioning equipment for the sports hall. The first part introduces the various types of buildings that have spaces greater than 4 meters and air-solving, basic information on the distribution of terminal elements of type nozzles and diffusers. The theoretical part is followed by the calculation of a project.

Project and problem teaching thematic area Diversity of Nature in the 1st Degree of Elementary School
ČECHOVÁ, Lenka
The aim of this thesis is to develop its own concept of learning material dedicated to teaching diversity of nature at first level of primary schools using principles of project teaching and teaching opportunities beyond elementary school. The proposed educational material is created in the form of a methodological manual that contains worksheets for proposed projects in the field of diversity of nature. That means a guidebook for teachers that is designed as an assistant for work with the proposed projects. There is also available an instructional text so that it corresponds with principles defined by the applicable educational documents. The theoretical part of this thesis focuses on evaluation of the importance of this work in the context of FEP and SEP monitored schools. Other chapters are devoted to a functional analysis of textbooks and workbooks for the first level of basic evaluation that emphasises the importance of project teaching during teaching elementary science, natural science and geography.

Optimization and using mercury determination in air.
POSPÍCHAL, Aleš
In this master thesis, during 2009, 2010 and 2011, has been done measurement of total content of mercury in ambient air and soil air in urban and rural locations agglomeration of České Budějovice. The goal was to develop suitable method in order to provide sampling of air to evaluate rate of contamination from chosen locations. The aquaristic compressor was used for admission of air, thus collected air could pass through external amalgamator, which secured pre-concentration of mercury from air. Consecutively, captured mercury has been determined in laboratory by atomic absorption spectrometer AMA-254. In urban background locations has been found total average concentration of mercury in rate 4,01 +/- 3,5 ng.m-3 and urban locations influenced by traffic in rate 29,5 +/- 50,07 ng.m-3. The concentration of mercury in soil air taken from filter bed of constructed wetland (CW) was 16 +/- 9,44 ng.m-3 with average mercury flux 14,5 +/- 8,3 ng.m-2.h-1. In rural compared location has been concentration of mercury in rate 15,4 +/- 7,83 ng.m-3 and mercury flux in soil air was 16 +/- 9,3 ng.m-2.h-1 at this location. Significant differences in contamination of mercury among partial locations have not been ascertained to the exception. The statutory limit for amount of mercury in atmosphere is 50 ng.m-3, whose value has not been mostly reached in any of measured locations. Thus, it has been proved that air contamination is low at selected locations.

Factors influencing the escape and spread of harmful substances
TESAŘ, Martin
Currently, harmful substances are released to the air more often and they threaten the safety of people because of their increasing amount being operated, stored and transported in the Czech Republic. The present thread is that the disasters in which harmful substances are released do not occur sporadically. Unintentional release may appear during their treatment, storage or transportation for many reasons, especially due to a natural disaster, technical cause or human failure. New causes of release have occurred recently {--} malicious intent and terrorist attack.This thesis creates a complex view of the branches of science and other areas dealing with the spread of harmful substances in the air. Emission of harmful substances is influenced by many factors which are very difficult or sometimes impossible to model mathematically. There exist a lot of mathematical models which differ according to the factor they treat. They concern models of outflow, dispersion and evaporation.The fire brigade in České Budějovice uses only one calculation model for estimating the emission of harmful substances - model ROZEX 2001.The result of this thesis may be used as a model for analysis and assessment of harmful substance release.
