Modeling spatial interactions on the example of the regional cities
Zelenka, Jaroslav ; Marada, Miroslav (advisor) ; Chmelík, Jakub (referee)
Management and planning of transportation is becoming more important in terms of continuously growing intensity of spatial interactions, which are still mostly realized through transport networks. That's why we can deal with this specific problem of transportation geography using for example spatial interactions modeling. The general aim of the thesis is modeling of spatial interactions and their subsequent comparison with real flows by using calibration in order to predicate the future value of flows taking the planned changes in the transport network in consideration. The main tool used to achieve the goal of the thesis is the gravity model which was applied on the example of regional capitals in the Czech Republic. Based on accomplishments we may say, that centers with lower significance of monitored relations are characterized by further location towards most centers, small number of inhabitants, low intensity of model interactions and lower values of transport intensities with neighboring centers. With the center growth itself, its range of interactions with other centers grows as well. Key Words: spatial interactions modeling, gravity model, model interaction, transport intensity, regional capitals

Enterohepatic circulation of bilirubin
Zelenka, Jaroslav ; Vítek, Libor (advisor) ; Entlicher, Gustav (referee) ; Červinková, Zuzana (referee)
Bilirubin is a main physiological product of heme degradation possessing important antioxidant and antiinflammatory properties. On the other hand, it could be neurotoxic during severe unconjugated hyperbilirubinemia combined with insufficiency of blood-brain barrier (neonatal jaundice). It is secreted from the body via bile and is further metabolized in the intestine. Part of the substance is reduced to urobilinoids, part is adsorbed to the intestinal content and some part could be reabsorbed back to the systemic circulation. This enterohepatically and enterosystemically circulating fraction varies in size depending on the rate of bilirubin secretion, solubility in the intestine and intensity of its intestinal metabolism. Under specific circumstances, EHC and ESC may significantly increase serum and bile bilirubin levels and influence physiological as well as pathological processes occuring in the body. Among the most important is the protective elevation of UCB levels in Gilbert syndrome subjects and dangerous increase in severity of neonatal jaundice. In the presented thesis, the mechanisms affecting EHC and ESC of bilirubin and tools for further research in BP metabolism were investigated. The solubility of intestinal UCB is strongly decreased by addition of divalent cations. However, such approach to...

Czech prince and Saxon duke in 12th century. Comparison of the Czech principate and Saxon duchy of Henry the Lion
Zelenka, Jan ; Žemlička, Josef (advisor) ; Bláhová, Marie (referee)
If we resume the results of our comparison, we can see that the basic difference between the duchy of Saxony, territorial domain of Henry the Lion and Bohemian principality is represented by inner political structure of these domains. In consequent this inner political structure were also the chances ofthe emperor encroach diverged. The Saxonian duchy was a conglomerate of major number of aristocratic domains. The holders of these domains (bishops, earls ..... etc.) did not subordinate to fiats of the duke, they did not grant his authority. His power and support from emperor Frederick I. Barbarossa gave him a factual dominance over the other princes of Saxony however it did not let him to beared rule over them. His effort to enlarge his own principality threatened other princes's political positions and that is why they were in constant opposition

Struggle for Šwidnica-Jawor duchy under the reign of the Luxembourg dynasty
Zelenka, Jaroslav ; Vorel, Petr (referee) ; Bobková, Lenka (advisor)
Shire of successors of Boleslav I. of Svídnice (Schweidni tz, Swidnica) represents an anomaly in the history of Silesia. Dukes of this branch of Silesian house of Piasts were thoroughly refusing to became vassals of czech king by profi ting of their rel a tionship wi th Wi ttelsbachs, Habsbourgs, Anj ous, as well as wi th polish king Casimir III of Poland. Bolek II of Svidnice was the most powerfull adversary of Luxembourgs. Even by using a military force, John of Luxembourg couldn't break his opposition. Situation had radically changed by the Treaty of Namyslov (Namslau, Namyslów) between Charles IV and Casimir III of Poland in 1348. By this treaty, polish king officially renounced to support his nephew. Charles IV was aware of quali ties of Bolek II and he didn't want to loose him by blessing his ego. So he didn't choose the way of violence, but he gave him a lot of privileges to "buy" his support. Czech king offered to Bolek II the alliance that he couldn't refuse. By this alliance he allowed Bolek to fulfill his power ambi tions what should have never been done, if he had remained adversary of Luxembourg's. Bolek I I of Svidnice was capable to profit from this extraordinary favor until his death. He succeeded to j oin to his shire numerous territories and assure some important economic privileges for...

Czech prince and Saxon duke in 12th century. Comparison of the Czech principate and Saxon duchy of Henry the Lion
Zelenka, Jan ; Bláhová, Marie (referee) ; Žemlička, Josef (advisor)
During the reign of Henry the Lion was Saxony divided into number of "principalities". Holders (bishops, earls etc.) of these domains didn't stay under the command of the duke. They didn't grant his authority. Henry the Lion reigned only over his own principality. His power and support of Emperor Frederick Barbarossa gaye him factual dominance over the other princes of Saxony, but not the rule over them. Consequently was his primary interest not the rule over entire duchy, but the enlargement of his own property. He ruled in his own principality like superior suzerain. Problem of his principality was inner "disunion" .The domain was put together from allod and fiefs. Because of his fiefs was Henry in fact only one part in network of feudal relationships - on one hand the suzerein, on the other the fief. His suzerain position meant not, that he could ruled over his vassals like absolute monarcho His extreme requirements on his vassals activated their oposition. This inner conflict culminated in the time of clash.with emperor and caused animosity of his own vassals. The struggle with princes and the emperor has shown lirnits of his power and also incompact structure of his principality. Even his vassals came over emperor. His duke honour was taken from him. The duchy was divided and invested on other princes....

Interactive board in physics education
ZELENKA, Jakub
The thesis discusses using an interactive board in teaching science (physics) in the second stage of primary school. The thesis is divided into different parts dealing with technical principles of different interactive boards and the implementation of these boards into teaching science at primary schools. Using special software, the author created a set of teaching materials that was tested in practice. The test results were discussed with a qualified teacher and with the supervisor of the thesis. After that, the materials were adjusted so that their use would comply with targets of the thesis and their further use would be comfortable for teachers. To use the materials in a comfortable way, a comprehensive guide on their use was prepared.
