Polák, Miloš ; Hák, Tomáš (advisor) ; Kočí, Vladimír (referee) ; Vladík, Jaroslav (referee)
This thesis is a comprehensive study describing and quantifying material flows of waste electric and electronic equipment (WEEE) in the Czech Republic; specifically the material flow of small waste electric and electronic equipment (s-WEEE) as well as representative substances. The studied material flows were estimated regarding aspects of the environmental impact. The End-of-Life mobile phone is seen as a typical representative of s-WEEE ; therefore material flows of mobile phones are described in this thesis as well. To put it in concrete figures, approximately 124 thousand tons of WEEE from households originated in the Czech Republic in 2010, where each inhabitant got rid off 4 pieces of WEEE in average. Further, total production calculating also consumer-like WEEE from companies and institutions was around 141 thousand tons in 2010. S-WEEE present around 15% from the total amount of WEEE originating in 2010; however it is more than 80% as regards the number of pieces. Despite of that fact the recycling potential of Au for instance is slightly higher by s-WEEE than by large WEEE (63kg/year compared to the 59kg/year respectively). As regards estimation of the total production of EoL mobile phones, around 45 thousand pieces originated in the Czech Republic between the years 1990-2000 and 6,5...

The influence of energy mix on environmental impacts of waste management
Dočekalová, Veronika ; Kočí, Vladimír (advisor) ; Trecáková, Tatiana (referee)
This paper presents energy mix of Czech Republic and its effects on environmental impacts of waste management. Three technologies: landfilling without energy recovery and landfilling and incineration with energy recovery are assessed using LCA. Results for 1 t of mixed municipal waste are compared in 9 impact categories: abiotic depletion, acidification, eutrophication, global warming, ozone layer depletion, photochemical ozone creation, human toxicity, terrestrial ecotoxicity, freshwater ecotoxicity. Landfilling without energy recovery was evaluated as the most harmful technology to the environment, incineration as the most environmentally-friendly one. The use of Czech energy mix made impacts of the energy recovery technologies look lower, contrary to burdens of landfill without energy recovery that resulted higher. The influence of energy mix composition change is discussed further.

The most common knee injury in volleyball
Přádová, Kateřina ; Crhonková, Radka (advisor) ; Čech, Zdeněk (referee)
A knee is the most complicated joint in our body. It is commonly injured during volleyball, mainly resulting as a knee pain syndrome or an acute rupture of an anterior cruciate ligament. In its theoretical part this bachelor thesis gives an overview of basic anatomy and biomechanics of the knee joint, it deals with the gender differences in morfology and neurophysiology and it contains a chapter dealing with biomechanics of the knee joint in volleyball. The second part of this bachelor thesis is a research study searching for the most common knee injury in volleyball, comparing differences among men and women and comparing differences between indoor and beach volleyball. The most quoted injury of the knee joint was the injury of the ligament, but as the most serious and the most common injury players named an overuse injury. We didn't manage to compare an incidence in indoor and beach volleyball due to the lack of data. We didn't find a significant difference in the incidence and a character of injuries among men and women.

Cabejšková, Zuzana ; Kočí, Vladimír (advisor) ; Pivokonský, Martin (referee)
Charles University in Prague Faculty of Science Institute for Environmental Studies Ecology and Environmental Protection Environmental Protection Bachelor Thesis - Abstract Life Cycle Assessment of Water Treatment Technology Posuzování životního cyklu výroby pitné vody Author: Zuzana Cabejšková Supervisor: Doc. Ing. Vladimír Kočí, Ph.D. Prague, May 2012 Abstract (English) This bachelor thesis consists of a Life Cycle Assessment (LCA) of two water treatment plants (WTP) in the Czech Republic. The first WTP is situated in Hrdějovice in South Bohemia and treats underground raw water. The second WTP is in Central Bohemia and treats surface water from the Želivka reservoir. The pumping of raw water and its subsequent treatment were considered for the purposes of LCA; other phases of the life cycle of potable water such as distribution weren't taken into account. Waterworks companies provided data on consumption of energy and materials. Based on this data, the environmental impacts of 1m3 of treated water were calculated and a comparison of the two WTPs within different impact categories was performed. It was found that WTP Hrdějovice has a four-time lower overall environmental impact than WTP Želivka. Global Warming Potential, Acidification Potential and Abiotic Depletion of fossil fuels were identified as the...
