Perovskite-based optical sensor
Frkáň, Lukáš ; Jandová, Kristýna (referee) ; Novák, Vítězslav (advisor)
The aim of this Master´s thesis is to frame the concept of perovskite-based materials, provide basic information about perovskite-based materials and scrutinize their potential in terms of optical sensors manufacturing. The thesis also deals with monitoring of the sample in terms of long-term stability. The analysis of measured characteristics and their properties is included in this semester thesis as well, along with the methodology of testing and evaluating of the results.

Risks of vegan diet
Knotek, Filip ; Chrpová, Diana (advisor) ; Pánek, Jan (referee)
Veganism, in the last few years more and more popular way of eating, is sometimes presented by non-academic articles as "the best" and without risks. However, compete omission of all animal products doesn't have to be as safe as it seems at first sight. The aim of this thesis is to find out what is the knowledge of vegans about the risks of fully vegan diet and also what are their eating habits to eliminate those risks. The theoretical part is mostly focused on risks related to deficiency of essential nutrients. The practical part was focused on research, that was made by anonymous quantitative survey method. The questionnaire was composed of sixteen questions oriented mostly towards knowledge of risks of vegan diet as well as towards eating habits of respondents. A total of 187 respondents met the criteria necessary to be included in the research. The results showed that 80,7 % of vegans know that there are some risks connected to vegan diet. Those respondents had quite good knowledge about the risks summarised in theoretical part of this thesis. Mostly they underestimated the risks of deficiency of omega 3 fatty acids, vitamin D and generally the risk of mineral's deficiency. The eating habits of most respondents often reflected their knowledge about the deficiencies in vegan diet - on average...

Application of electric resistivity tomography in assessing odl gold mines Kometa
ŠEFČÍK, David
The aim of this diploma thesis is to test the possibility of using the geoelectrical resistivity tomography in tracing mining areas within the territory of the medieval gold-mines "Na Kometě" in the Písek Mountains and subsequently, based on the measured data, to estimate the simplified characteristics of the bedrock to a depth of 16 metres. The student will get acquainted with the basic geophysical instrument ARES as well as the basic interpretation of the data. The diploma thesis deals with basic geophysical instruments as well as with the occurrence of gold in the territory of South Bohemia. The submitted thesis has 129 pages and is divided into ten chapters.

Goldmine Roudný
Babický, Jan ; Teodoridis, Vasilis (advisor) ; Hanel, Lubomír (referee)
The presented bachelor thesis deals with the age-old phenomenon of gold, which initially was characterized as an element and as a mineral focusing on its properties and current and historical occurrence and mining in the World and the Czech Republic. Furthermore, the thesis also characterizes the former goldmine Roudný with the description of the geology, gold deposits, history of mining and description of processing technology of the gold ore. The following part devoted to nature and landscape protection in the former goldmine Roudný including an analysis of the negative consequences of the re-mining in the study area. KEYWORDS: gold, mineral, ore deposit, mining, protection, nature.
