The effect of oviposition on egg quality at the beginning and end of the laying cycle
Greglová, Ellen ; Tůmová, Eva (advisor) ; Michaela, Michaela (referee)
The egg quality is affected by many factors, among which various interactions may occur. The aim of the diploma thesis was to assess changes in the quality of eggs laid in the morning, midday, and in the evening at the beginning and the end of the laying cycle in six laying hybrids: Bovans Brown, Bovans Sperwer, Isa Sussex, Moravia Barred, Moravia BSL and Dekalb White, each individually housed in cages. The experiment was realized at the beginning of lay, between 19 and 26 weeks of age and at the end of lay betwen 64 and 70 weeks of age. During the experiment, were conected eggs at 6 a.m., 9 a.m., 12 p.m. and 5 p.m. and were recorded daily. In total, 300 eggs from each genotype and of each period were evaluated. At the beginning of the laying cycle, the interactions of oviposition time and genotype (P 0.03), were observed in the yolk weight (P 0.004) and the color of the yolk. The highest weight yolk had the eggs laid by white-egg hybrid Dekalb White early in the morning (13.79 g at 6 a.m.) and during the day the weight of yolk decreased. However, the yolk weight of brown-egg Bovan Brown hens increased until 9 a.m. and then decreased again. The darkest yolk was laid by genotype Bovans Brown at 12 p.m. (8.0 g), while the lightest yolk was laid by Dekalb White at 12 p. m. (3.00). At the end of the laying cycle, interactions of oviposition time and genotype (P 0.028) were observed in the albumen percentage. The highest values had hybrid Moravia BSL with eggs laid in 12 a.m., 5 p.m. 64.23 %, 63.33 %), and the lowest percentage had hens of Bovans Sperwer at 9 a.m. (58.19 %). Oviposition time significantly (P 0.003) affected only the strength of the shell. At the beginning of the laying cycle, we recorded higher strength at 9.00 a.m. (54.89 g.cm-2) compared to the eggs collected at 6 a.m. and later (41.39 a 24.58 g.cm-2). The genotype (P 0.005) affected most of the parameters of quality.

Creating a microclimate of an industrial building with high demands on its uniformity
Tůmová, Eliška ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
This diploma thesis deals with the optimization of microclimate of an industrial building. There is required constant temperature with minimal fluctuations during manufacturing process in the building. Due to insufficient cooling power of air-conditioning system was objective to design a solution that ensures stability of internal temperature during production especially in summer and simultaneously should be the solution economically acceptable. Simulation shows original state defined problems. Some new or unusual materials for solar shading are reviewed in the thesis by the experimental measurements and by the comparative method. To each material is assigned shading coefficient according to Czech standards, thereby is achieved universality for calculations of heat gains resulting from solar radiation. By one part of the experiments and their evaluation is determined thickness of the standard single glass glazing. It is also determined proportional transmittance of solar radiation for certain multiwall polycarbonates, which are currently used as fillers of industrial skylights and production hall‘s window openings. From experiments resulting design is subjected to the simulation. Comparison of temperatures is shown for the time before the installation of designed solar shading and after the installation of the solar shading.

Sanitation installation and gas installation in multifunctional house
Tůmová, Eliška ; Bárta,, Ladislav (referee) ; Vrána, Jakub (advisor)
Bachelor's work deals with sanitation instalations and gas piping. The teoretical part deals with design and implementation of retention tanks and infiltration facilities according to current technical regulations and their funcionability. Calculation and project part contain design of water installations, drainage, gas piping in building and their connection to present technical networks. Building is threefloor multifuctional house which has partial basement. Every floor differs in placing of sanitary rooms. Project was done according to current czech and europe regulations.

The classroom climate
TŮMOVÁ, Eva
This work deals with the classroom climate. The aim is to measure and compare the classroom climate at chosen South Bohemian primary and secondary schools. The work consists of two parts. The first part is theoretical and deals with the basic concepts related to the classroom climate. It deals with the school class as a social group, the position of students in the group, key players and climate determinants as well as with the developmental stages of adolescence, also with the differences between elementary and secondary grammar schools and the possibilities of measuring classroom climate. The second part, which is the fundamental for this work, defines the objectives, assumptions and research methods. In conclusion, the measurement results, their interpretation and verification of assumptions are set.

Psychological and analytic novel in the period of 30th and 40th of 20th centrury.
TŮMOVÁ, Eva
The thesis is orientated on psychological and analytical prose of 30s and 40s years of the 20th century. It describes its tendency in these years and then it detailed deals with Jaroslav Havlíček?s prose. The thesis is focused on three books where we can find the stard and the end of Havlíček?s work. It is concentrated on the most important elements that can be found in Havlíček?s prose. There are especially disease and death. The element?s of death and disease are showed a little bit differently each of these three books. So they are compared in the end of this thesis. Main character?s psychological movements are also not forgotten.

Financial analysis of the travel agency EXIM Tours, a. s.
Tůmová, Eva ; Holečková, Jaroslava (advisor)
The bachelor thesis deals with the financial analysis of the travel agency EXIM Tours, a. s. The thesis is divided into two parts. The first part is theoretical. It includes the description of the basic methodology of the financial analysis and the definitions of the indicators used in the financial analysis. In the second part, the company EXIM Tours is introduced and its financial situation is evaluated using the financial indicators described in the theoretical part. The figures have been monitored for the last four financial years (from 2007 to 2010) and they are compared with the recommended figures. In some cases, they are compared also with the figures achieved by its competitors.
