The role of renewables in the energy mix Czech Republic
Koukalová, Blanka ; Hladík, Miroslav (advisor) ; Czesaný, Slavoj (referee)
This thesis analyses the energy mix of the Czech Republic with a focus on the use and development options of individual types of renewable energy sources. It also considers economics of renewable energy especially in terms of production cost of electricity and the impact on the prices of electricity. The paper further analyses the current subsidies related of renewable energy sources in the country and forecasts such subsidies to 2030. The topic of the work is very timely as the future direction of the energy sector is the subject of intensive debate and negotiations, both at the level of the EU and the Czech Republic, namely in the State Energy Policy of the Czech Republic. The theoretical part defines the issue of renewable sources of energy and legislation related to the issue. It also deals with assessing the arguments of proponents and opponents of renewable energy sources and theoretical approaches related to renewable energy, specifically environmental and behavioral theories. Behavioral theory has a significant influence on decisions about the future direction of energy. The practical part focuses on the analysis of various types of renewable resources and subsidies related to renewable energy sources in the country. Furthermore we compare the models of energy systems and energy mixes of Czech republic and Germany, from both the current and future perspectives. We also evaluate the relationship of populations of the Czech Republic and Germany to renewable energy, which leads to the hypothesis that the development of renewable energy sources depends to some extent on political ambitions and objectives of the ruling establishment.

Hollow cone valve capacity in the restricted outflow conditions
Nehudek, Adam ; Haluza,, Miloslav (referee) ; Šulc, Jan (advisor)
The thesis aims to determine the influence partial or complete submerge of hollow cone valve by outflow on its capacity without space restrictions, by outflow into discharge chamber and by outflow into water tunnel of circular cross section. The valve capacity is for mutual comparability purposes usually characterized by discharge coefficient. Research works have been performed on a spatial hydraulic model of the valve with inlet diameter D = 67 mm and an apex angle of a cone 90°. Values of the discharge coefficient obtained from measurements were statistically analyzed. The dependence of discharge coefficient, expressed by energy head, on submerged level was approximated by an exponential function. Exponent value of this function express the dependance rate of valve capacity on downstream water level. This procedure didn’t demonstrate signifiant dependance downstream water level on hollow cone valve capacity, only on tests at outflow to water tunel showed a low increase in the discharge coefficient partly due to the influence of kinetic energy of the stream flowing out of the tunnel on the energy head and also due to underpressure. Independence of discharge coefficient value on valve head has been prooved for head greather than 232 mm. Also was defined 3 stages of interaction outflow jet from valve and downstream water, some of them may cause on real waterworks structures unfavorable situations (may affect excessive load on valve by pressure pulsations). The presented results allow better evaluation of bottom outlets capacity at higher water levels, when the valves are flooded. Significant effect of sufficient aeration (especially in long water tunnels) on valve capacity was also confirmed. Taking into account on the specifics of hollow jet valves and cone valves, it is possible to generalize some of this resultos on them as well.

Background: Energy expenditure in pregnancy of Czech women is a lowly explorer part of energy metabolism. Objektive: The purpose of this study was to estimate total energy expenditure in Czech pregnant women in gravidity and to compare our values with values presented in foreign literature. Design: Energy expenditure was estimated in 137 Czech women. Total energy expenditure was estimated from filling date each activities, which pregnant women filled to questionnaires and activities missed in guestionnaires wrote to paper. Seven days activities was estimated in a specially designed program GraphPad Prism 4. As the values of total energy expenditure were considerated program values calculated multiplication factors (1,035; 1,062; 1,177 for the first, second and third trimester of pregnancy. There is described also other energy characteristics - i.e.basal metabolit ratein the study Result: In our study there was total energy expenditure 2993 ± 599,6 kcal/day on average.There was seen a gradual increase total energy expenditure 2415 ± 533,9 kcal/day for first trimestr, 2719 ± 457,3 kcal/day, for second trimester and 3223 ± 586,5 kcal/day for third trimester. BMI group <19,9 was 2295 ± 239,3 kcal/day TEE, BMI group 20 - 26 was TEE 2800 ± 383,3 kcal/day and BMI group > 26 was TEE 3554 ± 532,6 kcal/day....
