Psychological aspects of identification and its use in forensic context
Molnárová, Monika ; Gillernová, Ilona (advisor) ; Urbanová, Miluše (referee) ; Netík, Karel (referee)
This dissertation thesis is an overview study of recognition of human individuals and its role in forensic identification. It begins with basic structures of identification, meaning and usage of mug books, facial composite identification, and for the most part, recognition. We discuss suitability and feasibility of these methods and base the reasoning on the results of research from other countries. Such methods are undoubtedly affected by eyewitness's identification accuracy and therefore we also focus on factors influencing this. We group the factors by the ones which can and the ones which cannot by affected by law enforcement while we pay a special attention to the variables which are objects of scientific research, such as sequential lineups versus simultaneous lineups, foil selection, age, race, and confidence of the eyewitnesses who are performing the identification. Finally, we include a practical administrator's manual which describes the identification procedure step by step in a greater detail: how to create photo arrays, live lineups, facial composite recognition, and mug books, how to instruct eyewitnesses, and how to supervise the entire lineup procedure up to documenting it. The guide is based on many U.S. manuals and contains standalone recommendations as well as explanations why some...

Czech compositions for string orchestra 1945-1968
Popelka, Jan ; Douša, Eduard (referee) ; Slavický, Milan (advisor)
Tvorbě pro smyčcový orchestr dosud muzikologická literatura nevěnovala přílišnou pozornost. Nejenže neexistuje žádná práce sledující námi vymezený časový výsek, ba nepodařilo se najít žádnou studii, která by se věnovala jakémukoli historickému úseku tvorby pro toto obsazení, a to jak u nás, tak v zahraničí. Ani slovníková hesla neuvádí smyčcový orchestr jako specifický druh souboru, ačkoli takové soubory existují. Faktem ovšem je, že řada skladatelů zanechala ve svém odkazu dílo určené smyčcovému orchestru, jen málokterý autor se však tomuto druhu tvorby věnoval soustavněji. Historii tvorby pro smyčcový orchestr lze přitom sledovat hluboko do minulosti nejen po linii serenády až k Mozartově Malé noční hudbě, v pozadí lze tušit také renesanční zálibu v jednotné barvě nástrojových rodin. Kromě Mozartovy serenády patří k často hraným skladbám určeným pouze pro smyčce Bachův třetí Braniborský koncert či Corelliho Vánoční Concerto grosso, nicméně nás zajímá smyčcový orchestr spíše v době, kdy je již konstituován orchestr symfonický. Tedy v době, kdy skladatelova rozhodnutí pro užití smyčcového orchestru je vědomou volbou založenou na požadavku jednotné barvy a zvukově kompaktního tělesa či komornějšího zvuku a nebo na objednávce konkrétního tělesa. Ke klasickým dílům 19. století patří zejména Čajkovského...

Legal issues of protection of sound recordings of musical compositions
Grishina, Marina ; Boháček, Martin (advisor) ; Votava, Tomáš (referee)
In my diploma thesis i deal with legal aspects of the protection of sound recordings of musical compositions in the Czech Republic and the Russian Federation. In connection with the development of modern technoligies that facilitate access to copyright works, for example the internet, protection of copyright and rights related to copyright is becoming a very important and should be corresponding. The first chapter deals with the definition of the basic concepts of copyright. The second chapter focuses on the issue of copyright infringement and infringement of related rights in the Czech Republic and Russia. In the following section copyright's international treaties (TRIPS, ACTA and others) are analyzed and liabilities, which arise from them. The fourth chapter deals with the issue of enforcement of copyright. In the last chapter, I compare effectiveness of Czech and Russian legal norms for the protection of copyright, based on anonymous sociological research among university students relatively to the origin of audio recordings of musical compositions.

Financial analysis of selected business entities
Jícha, Štěpán ; Homolka, Jaroslav (advisor) ; Michal, Michal (referee)
The thesis deals with the financial analysis of the Bernard Family Brewery and comparison with the Svijany Brewery. Methods, which are used to compare, are indicators of financial analysis represented by: absolute, differential, ratio and composite indices, spider graphs, bankruptcy and credibility models and indicator of economic value added. There are mentioned the specifics in the production of beer in the Czech Republic and the basic characteristics of the company. Indicators are calculated for the years 2010 to 2014. The results are compared with rival Svijany Brewery and with average in manufacture of beverages industry (where possible). In the conclusion, there is given an overall evaluation of results and formulation of possible recommendations for improving the financial situation of the Bernard Family Brewery.

Influence of seasons on the pollution of selected water bodies in the Příbram region
Vaňková, Petra ; Vach, Marek (advisor) ; Heřmanovský, Martin (referee)
The objective of this Diploma Thesis is to evaluate the impact of water quality factors and year-seasons factors on the development of pollution levels in three ponds located in the Příbram area.
The theoretical part of the Thesis focuses on different aspects related to the study of surface water. It elaborates on the types of water, their chemical analysis, the classification of surface water, measuring methods, and the theories of anthropogenic pollution. The sources for the theoretical part were selected from relevant scientific literature focusing on surface waters and their chemical composition.
The practical part of the Thesis contains detailed description of the focus location and the three specific ponds, the methods of sample collection and analysis applied, and of the processing, assessment, evaluation and interpretation of results. The pollution concentration indicators were measured through laboratory analysis of the collected samples. The Thesis contains measurement results for the levels of ammonium nitrogen, nitrates, nitrites, phosphates, chromium, lead, cadmium, copper and nickel.
The collected evidence revealed significant pollution levels in the measured ponds. The pollution was found to be of anthropogenic origin, and caused predominantly by agricultural activity and contamination by waste water. Research data indicates that all water objects under examination show comparable levels of pollution. A strong correlation between the values of pollution indicators and the season of the year was established for nitrates and phosphates. On the other hand, levels of ammonium nitrogen show merely a slight correlation with the season of the year.

Microbiological quality of milk for cheese production
Korous, Jan ; Legarová, Veronika (advisor) ; Vladimír, Vladimír (referee)
This bachelor thesis is focused on microbiological quality of milk for cheese production. Besides that, it informs about the composition of milk and the processes in cheese production.
The composition of milk differs between animal species. Lactose is the main sugar of milk, with content about 4-8 %. The majority of fat found in milk is triacylglycerol type. Casein is the most important protein, which occurs in three fractions (alpha, beta a kappa). Milk also contains various minerals and vitamins. The most important mineral is calcium, which plays an important role in cheese production. The milk composition is a suitable environment for the growth of microorganisms (Pseudomonas, Enterobacter, etc.), that can contaminate raw milk. Despite this risk, the raw milk is commonly used for cheese production, because it gives the cheese better structure and taste compared with the treated milk. However, the majority of cheeses are manufactured from the treated milk. In most cases, the milk is treated by heat, especially by pasteurization and ultrahigh temperature. These procedures kill microorganisms in milk. In some cases, milk can be contaminated again after the treatment or by inactive spores that survived the treatment. They can become active under favourable conditions, for example during cheese making.
Cheeses can be divided into groups by several criteria (type of coagulation, water content or fat content in dry matter). Starting cultures are used during cheese making from treated milk. Thermophilic starting culture Lactobacillus casei is used for manufacturing of soft cheeses and cheeses with high-heated curd. Cheeses with holes are made by fermentation (Propionibacterium freudenreichii). Mesophilic bacteria Lactobacillus lactis are used for production of cheeses with low-heated curd. There are many other cultures used in cheese making. Another important process during a cheese making is coagulation. During this process, the milk fat is coagulated by enzymes (chymosin, pepsin). After the coagulation, the curd is cut and forms soft grains, which exude whey. The grains are often heated for the better whey secretion. Salt is used during the cheese production to slow the activity of microorganisms and enzymes and it also gives better taste to the final product. Cheese is then let to age, during this period of time, biochemical processes occur and unique characteristics of the cheese are gained.
