Řezník, Jindřich ; Duchan, David (referee) ; Špano, Miroslav (advisor)
The subject of this thesis is the enumeration and analysis methods applicable to the calculation of loads on bridges from water and water-borne objects. It involves a hydrodynamics loads, loads from captured debris and from impacts of the individual water-borne objects and their clusters. It includes an assessment of the current situation, the teoretical analysis and model calculations on the concrete bridge with the evaluation of usable methods.

Ryzová, Leona ; Pourová, Jana (advisor) ; Vopršalová, Marie (referee)
1 ABSTRACT Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Leona Ryzová Supervisor: PharmDr. Jana Pourová, Ph.D. Title of diploma thesis: Cardiovascular effects of silymarin Aim: The aim of the diploma thesis is to summarize the existing knowledge about the mixture of natural plant substances collectively referred to as silymarin and to map the results of the latest studies focusing on the cardiovascular effects of silymarin. Main findings: Available data suggest that silymarin has positive effects on the human body, including hepatoprotective, choleretic and cholagogic, neuroprotective, anticancer and antiviral, anti-inflammatory and positive effects on diabetes mellitus. Positive effects on the cardiovascular system include protective effects on the vascular endothelium, antioxidant effects, beneficial effects on blood lipids, regulation of blood aggregation and antidiabetic effects. Although the conclusions from cardiovascular studies are not always the same, most confirm the positive effect of silymarin on the cardiovascular system. A necessary part of future research will be the search for new dosage forms in order to increase the bioavailability of silymarin, which so far limits its clinical application. Conclusion: Silymarin is a mixture of...

Legal responsibility for marine pollution
Pekařová, Markéta ; Žákovská, Karolina (advisor) ; Sobotka, Michal (referee)
This diploma thesis deals with the problem of oil pollution of the marine environment caused by vessels. At the beginning of the thesis, the most important international agreements dealing with the protection of the marine environment and conventions regulating the cooperation of states in the elimination of the consequences of oil pollution are introduced. The thesis focuses mainly on the international conventions governing liability of an individual entity due to oil pollution of the oceans, but also briefly deals with the question of the state liability. The work analyses relevant US legislation, and compares this with an examination into the stance of the European Union and the Czech Republic with regards to this problem. In conclusion, some provisions of the international conventions are subjected to criticism and possible changes to the legislation are proposed.
