Is subvention program supporting production of electricity in photovoltaic plants in the Czech Republic efficient?
Vaniš, Miloš ; Mičúch, Marek (advisor) ; Zajíček, Miroslav (referee)
As a consequence of recent generous subvention program, supporting electricity production from renewable resources, number and size of installed capacity of the photovoltaic plants in the Czech Republic skyrocketed. Strikingly, using photovoltaic plants to reduce CO2 is the most expansive but paradoxically the most supported way to reduce emissions compared to alternative electricity production in the Czech Republic. Guaranteed producers' purchase price increases electricity prices for households and firms. Production of electricity in photovoltaic plants also encumber power transfer network. Purchase prices of electricity from photovoltaic plants were introduced to increase the share of electricity produced in photovoltaic plants on the overall consumption and to reduce CO2 emissions. Reducing CO2 emissions to stop climate change was the main reason for introducing photovoltaic subvention. Analysing the relationship between amount of CO2, number of photovoltaic plants and GDP on the data of selected countries showed that the production of electricity in a photovoltaic plants contributes nothing to CO2 reduction in short-term.

Stabilita vitamínů ve směsích pro parenterální výživu
Khýnová, Lucie ; Solich, Petr (advisor) ; Nováková, Lucie (referee)
Parenteral Nutrition (PN) is an alternative method of providing nutritional support for patients via the intravenous route. Patients selected for PN are malnourished patients or patients who have the potential to become malnourished. PN admixtures consist of fats, carbohydrates, proteins, vitamins, trace elements, electrolytes and fluids. Vitamins are believed to be among the least stable ingredients in PN mixtures and should be added immediately before commencing infusion. The purpose of this thesis is to obtain information on stability of the vitamins in PN admixtures depending on different storage conditions and different time. Water-soluble vitamins and fat-soluble vitamins were investigated in the mixture of Kabiven® Bag (Fresenius Kabi) with Vitlipid® N (fat-soluble vitamins) and Solvitio® N water-soluble vitamins) Adult Injections. There were prepared 6 Bags altogether, three with addition of trace elements contained in Additrace® concentrate and three Bags without trace elements. Assessing the chemical and physical stability was carried out after: zero time, 7, 14 and 29 days in a refrigerator followed by 24 hours and 48 hours storage at ambient temperature and day-light protected. Physical tests include pH, osmolality, microscopy and particle size determination by laser diffraction....

Vliv intensity míchání na filtrační cykly při úpravě vody
Pivokonský, Martin ; Pivokonská, Lenka ; Švec, Martin
The aim of this contribution is to investigate aggregation efficiencies when high (G= 260 s-1) and low (G= 60 s-1) intensity agitation is applied for a treatment of surface water with high content of humic substances in a pilot size operation. It was established that high intensity agitation represented by a fluid layer of granular material (FLGM) can be more effective for an aggregation agitation than low intensity agitation with the help of the perforated baffles (PB). The FLGM improves performance of the filters because the filtration runs in the technological arrangement with FLGM took longer periods compared with low intensity agitation.

Private sector in public health care systems
Matějusová, Lenka ; Durdisová, Jaroslava (advisor) ; Běláčková, Vendula (referee)
This master thesis is trying to describe the situation of private sector in public health care systems. As a private sector we understand patients, private health insurance companies and private health care providers. The focus is placed on private health care providers, especially in ambulatory treatment. At first there is a definition of health as a main determinant of a health care systems, definition of public and private sectors in health care systems and the difficulties at the market of health care, including externalities, inperfect information and elasticity of supply and demand at this market. There is also the problem of financing health care as a mix of public and private payments, which is different in every health care system. The main focus is laid on the situation in the Czech republic. As a comparison there are described situations in Denmark, Germany, Great Britain and United States. The size of private sector in every health care system is different and it depends on different circumstances in particular state, including social-economic development, regulation of health care market from the state and the attitude of patients to private health care.

Effect of incubation temperature on phenotype in mallard
Cílková, Martina ; Hořák, David (advisor) ; Krist, Miloš (referee)
The influence of incubation temperature on bird neonate phenotype is widely studied. In waterfowl (Anatidae), maternal effect can be divided to two main parts: clutch formation and its incubation. Therefore, waterfowl are a good model for this type of study. The egg temperature can strongly influence embryo development and survival of the hatchlings. The goal of this work was to examine the effect of incubation temperature on hatchability, incubation length, sex ratio and phenotype of European Mallard ducklings immediately after hatching. Eggs were randomly placed in one of six incubation temperatures, which ranged from 35 to 39 řC. This range corresponds with temperature range in natural mallard nests in the Czech Republic. Eggs were then artificially incubated. Newborn hatchlings were weighted and their structural size was measured, then they were killed. Some hatchlings from incubation temperatures 35.5, 36 and 37 řC were used to examine residual yolk sac mass and basic chemical composition of the yolk-free body. Hatchability was markedly lower in both extreme temperatures (35 and 39 řC). Incubation length significantly decreased with increasing incubation temperature. I failed to prove the influence of incubation temperature on hatchling body mass, but I found temperature-dependent changes of...

The first land reform 1919
Korolus, Václav ; Jakubec, Ivan (advisor) ; Szobi, Pavel (referee)
The interwar Czechoslovak agrarian reform was put in motion to improve national agriculture production by way of the redistribution of the estates. The second goal was to eliminate the unwanted influence of the foreign (German and Hungarian) landlords. This huge project was held from 1919 untill it was officialy ended in 1935, but the idea of the land reform was significant in Czechoslovakia for a much longer period (mostly after World War II. and during the restitution processes). The interwar landreform changed more than 29% of Czechoslovakia (more than 4 million hectares were confiscated). Approximately one half of this amount was assigned to the alienees, the second half remained in the hands of the former owners. Both of the main goals were accomplished by this huge transfer of property. The smallest homesteads were extended using the land from the largest estates and became more effective. The properties of the landlords were decreased in size by one half and their influence on the national economy was reduced. Despite some imperfections in the reform laws and how they were carried out, the main targets were accomplished and I assume this project was successful. Better outcomes could be reached only with different conditions, like a longer period of time. In a comparison of other similar reforms, the Czechoslovak land reform was the third largest (after Russian and Romanian).

Hatching synchrony in birds
Tippeltová, Zuzana ; Hořák, David (advisor) ; Riegert, Jan (referee)
This bachelor thesis is about hatching synchrony in birds. Generally, among birds there are two types of hatching - asynchronous and synchronous- and the type of hatching is primarily determined by the time of the onset of incubation. In many bird species, including most precocial ones, incubation does not begin until the last egg has been laid, which results in hatching of all the eggs within a few hours. In synchronously-hatched broods, all the chicks are about the same age. Thus no single individual has an advantage in size or strength over any of its siblings in the nest. The survival probability is then similar for all chicks which maximizes number of fledglings under favourable condition. In contrast many species of birds begin to incubate as soon as the first eggs is laid and hatch their eggs asynchronously over a period of days or weeks, handicapping last-hatched chicks with an age and size disadvantage. Many hypotheses have been proposed to explain why female birds start to incubate before clutch completion and some of those suggest that asynchronous hatching is a parental strategy for raising the largest number of offspring that food resources will allow when the abundance of food for the chicks cannot be predicted at the time that eggs are laid. The selective pressures leading to the evolution of...
