Soukupová, Lenka ; Drahota, Petr (referee) ; Mihaljevič, Martin (advisor)
Lenka Soukupová, Zvětrávání arsenopyritu v lesních půdách v acidifikovaném prostředí SUMMARY The weathering of arsenopyrite (FeAsS) has been studied at the experimental site Načetín in the Ore Mountains, Czech Republic. There were chosen three areas with different vegetation (beech, spruce a unforested areas) at this site. The arsenopyrite samples were placed in all soil horizons (litter, horizons A, B and C for forest areas; horizons A, B and C for unforested area), where they were exposed to ambient conditions for one year. After one-year weathering, the newly formed secondary minerals were identified and the rate of surface oxidation was determined, both depending on the environment of oxidation. Although physical-chemical parameters and content of main and trace elements of the studied soils varied, the only detected crystalline secondary mineral of arsenic was scorodite (FeAsO4∙2H2O). Nevertheless, this differences affected amount of formed scorodite. The highest concentrations were determined on the surface of the arsenopyrite grains that oxidized in the beech stand, conversely the lowest concentrations were determined on the arsenopyrite grains from the unforested area.

Osmolality of parenteral preparations. Saccharides.
Mališová, Lenka ; Šklubalová, Zdeňka (advisor) ; Adámek, Roman (referee)
Solutes concentration is described by molarity in parenteral infusions. The knowledge of the osmotic concentration is also important from the therapeutic point of view. According to the Pharmacopoeia, each infusion has to be characterised by a value of its osmolarity. However, osmolarity cannot be measured. Measurement using osmometer gives osmolality, which relates to molality. The solution density is needed to perform conversion of molality to molarity and vice versa. To convert molarity to molality, the conversion factor f is needed to be defined. In case of the conversion of molality to molarity, measurement of the solution volume is needed. In this thesis, density of the solutions of glucose and fructose were measured in temperature range of 15- 40řC, both were prepared in molal concentration and molar concentration in range 0,1 - 1,0 mol/kg and/or mol/l, respectively. The equations for mutual conversion between molality and molarity were generated. The measured osmolality values were compared with the values of osmolarity estimated using three recommended methodes. Equation (8), which uses the water content in the solution, gave the most accurate estimation of osmolarity.

Possibilities of Using Some Elements of Project-based Learning in German Lessons in Secondary Schools in the Czech Republic
Zapletalová, Pavla
The project method is not an unknown method. Since the time of Jan Amos Komenský, in whose work some of its universal principles also appeared, it has occupied its rightful place among other methods. From the latest scientific points of view it ranks among activity-based methods and approaches. They particularly emphasize the importance of emotionally charged activities, the multi-sensory approach to the subject matter, and the close connection to the real world and real-life situations. A model formulated by the German pedagogue Herbert Gudjons, which significance lies primarily in the complexity of its conception, seems to be one of the most appropriate models of the project nowadays. The project method itself has its positive aspects but also certain difficulties and risks which we have to take into consideration when deciding what teaching method to use Moreover, as far as the foreign language teaching is concerned, some features of the general model of the project method are not applied in foreign language teaching at all or just partially.

The comparison of legal provisions setting down monetary remedies in intellectual property infringement cases
Sedláček, Václav ; Boháček, Martin (advisor) ; Macek, Jiří (referee)
The thesis deals with monetary remedies in intellectual property infringement suits, focusing on industrial property rights. On the background of enacting of the czech Act number 221/2006 Sb. which implements the directive 2004/48/EC of the European parliament and of the Council, the thesis compares these two texts with each other and also with the proposal for the directive KOM(2003) 46 final in their relevant parts. By doing this, it evaluates the directive and the czech act as the directive's implementation. This evaluation represents the secondary aims of the thesis. Comparison, analysis of factual articles and interviews with relevant experts practicising in the area show that by setting the damages as double the "customary" royalties, the czech Act in his § 5 ods. 2 represents a sanction, which confirms the hypothesis of the prevailance of an analogy between the czech provison and the punitive damages in american law. This fact creates scope for the hypothesis of existance of further analogies, the verification of which is the central aim of the thesis. Therefore, the second part of the thesis analyzes american provisions of the United States Code concerning copyright, trademark and patent law, and related caselaw. This is compared both to the directive and the proposal for it, moreover to the czech copyright Act number 121/2000 Sb. and in particular to the czech Act number 221/2006 Sb. The third part supplements the analysis of relevant czech court decisions. The second and third part identify similar and distinct elements of the provisions and reveal analogies in seemingly different institutes. Differences are spotted in the construct used to achieve the punitive function, furthermore between the terms "customary royalty" and "reasonable royalty" and also between the terms "bezdôvodné obohatenie", "infringer's profits" and "unjust enrichment". Conversely, an analogy is identified between the discretionary power of american courts to increase proven damages or determine statutory damages and the czech institute of "primerané zadosťučinenie" (appropriate satisfaction). The prevailance of prohibition of double recovery is another existing analogy between the american and czech law.

Spatial survey of cost of european companies in 2006
Chrástek, Michal ; Marek, Petr (advisor) ; Makovec, Martin (referee)
The content of this thesis is an investigation of selected companies from the European Union, with an emphasis on the Czech Republic in terms of indicators of incremental costs, total costs, labor productivity and average passenger load per worker. Thesis is focused exclusively on the company's primary and secondary sector. Data on individual companies, I draw from the Amadeus database. Ratios are calculated from data in 2006. The highest total cost, I noticed in Italy, Germany and Portugal. In contrast, the smallest recorded in Estonia, the Netherlands and Denmark. For labor productivity and average passenger load per worker based on the maximum value for the Netherlands, Denmark and Belgium. In contrast, with values not too proud in Bulgaria, Romania and Estonia. Czech Republic in most indicators fluctuated slightly below average among the selected European countries.

Possibilities of Karstification in the Transitional Facies of the Bohemian Cretatious Basin
Balák, František ; Bruthans, Jiří (advisor) ; Knížek, Martin (referee)
In the region of Bohemian Cretaceous Basin can be found some springs with specific yield over 100 l/s. The doyen of Czech hydrogeology Prof. Hynie described some of those springs to be of karst origin and as the most permeable area he described the so-called transitional facies between shallow-water sandstones and deep-water marlstones. Possibilities of karstification have not yet been studied for rocks in the BCB, so the origin of well-permeable pathways in the BCB is a subject of speculations. This thesis deals with the question of which sedimentary rocks potentially allow the generation of karst permeability in the BCB. To do so, rock samples drilled from outcrops in the BCB were subjected to a fast dissolution simulation by leaching in hydrochloric acid. Carbonate content is measured by a standard and one's own method. Mineral composition, grain size and microscopic structure of rocks are studied with SEM. As is shown, the border of rock karstification is not defined just by the carbonate content, but also the grain size, rock structure and by the occurrence of fine secondary silicate content. Concerning the amount of dissolvable compounds, the border of total disintegration can be at 30 % of carbonate content for some rocks, but the most resistant rocks (mostly fine rocks with SiO2 matrix) stay intact...

Adjusting the television picture and sound in newscast to make it more difficult to identify people (newscast of Česká televize, TV Nova and FTV Prima)
Sváček, Martin ; Lokšík, Martin (advisor) ; Štoll, Martin (referee)
The Diploma Thesis deals - within its theoretical part - with situations in TV news, which require conversion of audiovisual content to achieve involved person's anonymity. Ethics codes of analysed television stations are major factor in this part, also included as secondary support relavant studies, reference books, laws and edicts. Conversion of audiovisual content is necessary - speaking of victims of crime (mainly violent or sexual offense) and theirs relatives, children, suspects and theirs relatives, anonymous sources, some criminalists or other vulnerable persons. Practical part of the thesis applies gained informations to analyse audio-visual recordings - broadcasted by Czech TV (Česká televize), TV Nova and FTV Prima. Study reflected diffrences between conversion of same situations and same persons. Study also reflected some ethically controversial moments. Several reporters gived an interview to comment selected news.

Subsidy importance in rural development (Chanovice, Pačejov, Myslív and Velký Bor)
Koláříková, Markéta ; Kocmánková Menšíková, Lucie (advisor) ; Pavel, Pavel (referee)
The main goal of the study was to find out and compare the significance of the received subsidies in the development of Chanovice, Pačejov, Myslív and Velký Bor villages. My work in the first place dealt with subsidies as an important part of a village income and as a tool for their development.
The theoretical part is based on the study of special literature and other relevant sources relating to the examined issues. Attention is given to regional development, within which the two programming periods (2007 2013 and 2014 2020) are compared and also the financing of villages.
The knowledge gained in the theoretical part are followed by secondary data analysis, in which it was found that the received subsidies hold an important position in the structure of Chanovice and Pačejov village incomes in the two other villages that position is not so important. Thanks to received subsidies in the period 2007 2013 the villages implemented a lot of developing projects, either infrastructural (most Pačejov village) or other (especially Chanovice village) character. In the framework of the infrastructure based projects all municipalities used the subsidies to build and repaire their water and transport infrastructures. Another field where the municipalities aimed the subsidies was field of education.
Based on semi-structured interviews with mayors of selected villages the empirical part of my work was worked out afterward. The mayors share the opinion that the village development especially the development connected with infrastructure, the subsidies are necessary, but the way to obtain them is very difficult and costly for the small villages
