The properties of surface waters affected by coal mining.
FAFÍLKOVÁ, Veronika
I watched the chemical characteristics of wetlands and surface waters in the vicinity of Lake Medard. This lake is a residual hole (after brown coal mining activities) which is now being filled with water. It is situated in Sokolov cadastre. I used physical, chemical and biological characteristics of water to characterize the surface water. The values have been compared with indicators of other surface water ecosystems. They were compared with Eger river water and with water from the south Bohemian fishponds. Results of comparing showed that all parameters of observed waters are very different. Surveyed parameters of the average concentrations are several times higher or on the contrary lower at individual sites of interest. Sites of interest are characterized by high levels of dissolved substances in water. Particularly problematic are sulphate anion concentrations and concentrations of Na, Ca, Mg, Zn, Mn and Fe cations.

Do women with children have lower wage rate than childless women?
Lukášová, Nikola ; Brožová, Dagmar (advisor) ; Čermáková, Klára (referee)
The aim of the thesis is to demonstrate if women with children in the Czech Republic have a lower wage rate than childless women. The data from WageIndicator Foundation was processed by using the the least squares method. The conclusion is that motherhood has a negative impact on salaries. I also found that the depreciation of human capital influences only women with two or more children. It can be caused by the lenght of maternity leave. The main finding is that the wage penalty for motherhood actually exists. And the society and politicians should give the motherhood penalty more attention in the future.

According to this suggestion compile a model of marriage contract. The draft of rec-ommendation is compiled with the help of comparison with the Austrian statutory of matrimonial property relations and through questionnaire survey among students of University of Economics who have experiences with the adjustment of community property.

Interspecific hybridization in Acrocephalus warblers.
Majerová, Veronika ; Reifová, Radka (advisor) ; Kotlík, Petr (referee)
Acrocephalus warblers have gone through the adaptive radiation during last severalmillion years, which gave rise to thirty one species occupying mainly Eurasia,Africa and Australia. The majority of species are morphologically very similar,however, they differ in ecological requirements, migration strategy, and song.Interspecific hybridization seems to be quite common among Acrocephaluswarblers, not only between sister species, but also between more distantly relatedtaxa. The main goal of this study was to determine whether this hybridization leadsto gene flow between species and which factors affect the rate of interspecific geneflow. For this purpose we conducted population-genetic analysis in three Europeanspecies of the Acrocephalus warblers of the subgenus Notiocichla: reed warbler (A.scirpaceus), marsh warbler (A. palustris), and blyth's reed warbler (A. dumetorum).Our results based on the analysis of sequence data from eight nuclear loci indicate,that gene flow between the studied species occurs, but only in one direction. Thegene flow is higher between genetically more related species than betweenecologically more similar species. We also estimated that the reed warbler and themarsh warbler diverged approximately 1,1 million years ago. The blyth's warblerand ancestor of the reed and marsh warbler...

Differences between men and women in the Czech labour market
Stroukal, Dominik ; Kadeřábková, Božena (advisor) ; Pavelka, Tomáš (referee) ; Němec, Otakar (referee)
This thesis consists of five articles that apply current world research on labor economics at the Czech Republic and confirms the significant differences between men and women in this market. It shows that gender has a significant influence on the preference on the labor market and, consequently, on employment and health. First, the thesis shows that preferences are relevant determinant of career and then we study the difference in preference of salary for men and women. Subsequently it shows that gender plays a significant role in explaining the relationship between homeownership, and unemployment, as well as unemployment and health. The first chapter was able to demonstrate that the preference for a career has a positive influence on the choice of career. The influence of higher education on prioritizing career proved to be positive and significant. Probability of a career choice is reduced by the presence of children, however, is not dependent on their number, which is contrary to the theory of preferences. The second chapter shows that Czech women prefer more non-monetary rewards than men. It has also been shown that people with university education are same in the preferences of non-monetary rewards regardless of the gender of the respondents, however, compared to the world's research, the Czech higher education increases this preference. It turned out that women prefer risk less than men. The third chapter demonstrates that although the housing market undermines labor mobility and employment in the Czech Republic at the regional level, therefore, that in regions with a higher rate of home ownership is higher unemployment, at the individual level, the owners of housing are unemployed are less likely. The estimates are significantly different for men and women. Men living in owner-occupied housing have a higher likelihood of employment than women. At regional level, however, this thesis shows that the high rate of home ownership increases unemployment for both men and women, in the long run only to women. The fourth chapter showed that men transition to homeownership reduces the likelihood of unemployment next year. For women, this relationship has proved to be insignificant. In addition, as insignificant showed the opposite relationship, the transition from unemployment to the newly acquired home ownership. The last chapter shows that the change in the working status to unemployment will increase in the future probability of worse health. Influence in less than two years, however, proved to be significant. An important conclusion is that men have a significantly stronger relationship between health and unemployment than women.

Multicriteria games
Tichá, Michaela ; Dlouhý, Martin (advisor) ; Lachout, Petr (referee) ; Čičková, Zuzana (referee)
Theory of multicriteria games is a special field of game theory, when one or more players have at least two payoff functions and want to maximize simultaneously. The work introduces a number of new findings. It examined the concept of finding equilibria in pure strategies in noncooperative multicriteria game. It is possible to find all the equilibria in pure strategies by full search and solving two linear programs for each point. Furthermore, two linear programs are formulated for verifying that a selected point is the equilibrium of the game or not. In the noncooperative games is also introduced the concept that with knowledge of the equilibrium of bimatrix game determines preferences of the players. Although finding the equilibrium point of the bimatrix game is nonlinear problem, finding the preferences is linear problem. The latest findings in the noncooperative games is a generalization of the concept that solves multicriteria game by assigning weights to each criterion of each player. The work demonstrates that it may not be necessarily linear weights, but it can be more general function that describes the player's preference. The remaining part is devoted to knowledge in cooperative games. There is considered that the players know their preferences and are able to express them by weights. The game with known preferences is defined and solved with the use of bargaining theory. Then it is generalized to a case where players have more payoff functions, from which they can choose. Finally, the multicriteria case of voting game is defined. It is designed completely new concept, which selects the winning coalition in the voting game. This concept is then applied to the real situation after the elections to the Chamber of Deputies in 2013.

Růst Mycobacterium smegmatis na agarovém médiu a agarovém médiu pokrytém celofánovou folií - morfologická a proteomová studie
Ramaniuk, Volha ; Weiser, Jaroslav (advisor) ; Beranová, Jana (referee)
Biofilm formation is one of the most common bacterial survival strategies. Majority of bacterial species are able to form these three-dimensional structures, including pathogens like Mycobacterium tuberculosis. Representatives of Mycobacterium genus widely occur in the nature, although they can cause serious problems when they appear in medical equipment and artificial replacements of the human body. Non-pathogenic Mycobacterium smegmatis mc2 155 was used as a model organism in our experiments. We investigated morphology of the three- and six-day-old colonies (in fact biofilms) on agar and agar covered with cellophane using Stereo microscope and Scanning Electron Microscope. We found that a type of surface as well as a carbon source has a great influence on the morphology of the M. smegmatis colonies. We isolated proteomes from the agar and cellophane cultures and from planktonic culture. Two-dimensional electrophoresis was used as the main proteomic method. Proteomic data were analyzed using PDQuest software. Then the sets of proteins detected by qualitative and quantitative analyses were compared using Venn diagrams. As a result, we recognized 7 unique proteins that might be specific for recognition and adhesion of bacteria to the cellophane, no unique protein in agar proteome and 46 unique...

Chosen natural resources: focuses of conflicts nad its economic consequences
Sytný, Patrik ; Vošta, Milan (advisor) ; Sankot, Ondřej (referee)
The bachelor´s thesis aims to three chosen natural resources, which are petroleum, natural gas and water, and conflicts based on disputes over them. The aim of the thesis was to valorize nature of the conflicts, define their main focus and draw prospective economic consequences. Professional literature that deals with this kind of issue, was used in order to find out the true nature of the conflicts. The result is an evaluation, which has proven, that the most influental conflicts are rising over disputes over petroleum. Their economic and political impacts are very perceptible and economically measurable in the way of GDP, the total product and other economic indicators. In the thesis has been also proven that the conflicts on the basis of natural gas have similiar nature and extent as it is in the case of petroleum, even thought in a smaller amount. The least important conflicts in a meaning of economic impacts are those over water, by those has been proven, that they do not poses such an impact on economic and political situation as petroleum or natural gas nowdays.
