Topsoil application in reclamation practice advantages and pitfalls
Čížková, Barbora ; Frouz, Jan (advisor) ; Bartuška, Martin (referee)
This paper deals with spreading the topsoil to the dumps after brown coal mining as reclamation measure. Here I describe its advantages and disadvantages for soils and ecosystems restoring and the soil organic matter budget. Furthermore, I present here my pilot work dealing with long-term storage topsoil in stockpile and its impact on soil microbial parameters, especially microbial respiration and amount of biomass after stockpile disturbance. Soil used for the research came from different depths of excavated stockpile. The samples were measured for soil respiration by titration and amount of microbial biomass by fumigation-respiration method. The highest values were always measured in samples from greatest depths. It is due to greater making use of accumulated carbon, which becomes better accessible to microorganisms after erosion of stockpile. Keywords: brown coal, soil organic matter, reclamation, topsoil, post-minig sites

Organic dye decomposition by AOP´s methods
Olexová, Barbora ; Dzik, Petr (referee) ; Kozáková, Zdenka (advisor)
This diploma thesis is focused on the study of the influence of advanced oxidation processes on degradation of organic dyes. The field of AOP – very effective physically-chemical methods of wastewater treatment – includes application of strong oxidation agents, UV and ionizing radiation and electrical discharges. For this thesis, two of these methods were chosen – the application of oxidation agent (ozone) and UV radiation. Along with electrolysis, which is mentioned rather marginally in this thesis (it is the subject of the previous thesis), these phenomena are products of electrical discharge in water, where they participate in the processes of degradation in a different way. For all measurement series, two direct azo dyes were chosen as model substances – C.I. Direct Blue 106 and C.I. Direct Red 79. The ozonizer, in which either oxygen or synthetic or technical air were loaded as carrier gases, was used for degradation of dyes by ozone. The generated ozone was loaded into the bubbling vessel with dye solution of different initial concentration (10–130 mg.dm-3), which was followed by other bubbling vessel with KI solution for the next analytical determination of the amount of generated ozone. The other parameters changed were the gas flow (1–2 dm3.min-1), ozonizer output (minimal and maximal), type of dye, pH value of the solution (neutral or acid) and additional electrolyte (NaCl, Na2SO4 or any). The reactor for the study of the influence of UV radiation on degradation of dyes was an UV sterilizer into which the equivalent volume of dye solution was added. The possibilities of experimental settings were limited and only the type of dye, an additional electrolyte and pH value of the dye solution were adjusted (as in the case of ozone). Several series of samples were measured with various input conditions which more or less influenced the degradation of investigated dyes in this experiment. It was found that for both used methods the Direct Blue 106 dye was more degradable (with significantly better results for ozone than for UV radiation). The degradation of Direct Red 79 dye proceeded only by ozone treatment, in the case of the application of UV radiation no degradation occurred. By investigation of the influence of initial concentration of dye on its degradation, it was confirmed that with the initial concentration enhancement the final concentration rises as well, whereas in low concentrations (10–50 mg.dm-3) the initial concentration has no effect. The addition of an electrolyte had an accelerating effect on dye degradation in both methods (NaCl and also Na2SO4 showed similar results though the degradation proceeded in different ways). The addition of HCl accelerated the degradation only in the case of UV radiation; during the application of ozone the pH level of the system did not have any influence on the degradation. Oxygen and synthetic air had the strongest effect on ozone degradation (comparable results); in the case of technical air the final dye concentration was higher up to 30 %. The gas flow of 1.5 dm3.min-1 was stated as optimal with the ozonizer output 30 W (maximal). At minimal power the ozonizer produced very low amount of ozone.

Bills of exchange in the recent practice with special regard to types and admissibility of causal objections and relating decision-making
Švarc, Jan ; Horáček, Vít (advisor) ; Elek, Štefan (referee)
in English The thesis aims especially on questions concerning law of exchange which are not satisfactorily answered yet neither by academical community nor by judicial decisions made by the Czech courts and those which should be, from the point of my view, answered differently. In the first chapter, I tried to critically review various doctrinal definitions of bill of exchange and to draw up my own definition which affects bill of exchange complexly in its entireness. Second chapter is divided into three subdivisions chronologically. First subdivision refers to proofs of ancient documents congenial to contemporary bills of exchange. I have come to conclusion that the existence of bills of exchange can be proven as far as the beginning of the first millenium. Institute simmilar to the one of bill of exchange may be found in the Roman civil law. The second subdivision of second chapter assays medieval bills of exchange very thoroughly more than any other thesis on the same subject. All my ideas given are supported by quotations. The third subdivision briefly explains development of law of exchange in the modern period. The third chapter is dedicated to the general purpose of law of exchange and its modern usage with extra amount of attention paid to blank bills of exchange and collateral drafts....

ROK army participation in Vietnam War
Baboráková, Michaela ; Löwensteinová, Miriam (advisor) ; Glomb, Vladimír (referee)
This thesis addresses the participation of the Republic of Korea Army in the Vietnam War. It is a not very well known fact that the Korean Army was the second largest force allied to the United States in South Vietnam. Korean participation still carries a certain amount of controversy, especially in regards to Vietnamese/Korean relations. The Republic of Korea deployed to the Republic of Vietnam two infantry divisions and one Marine Corps brigade. The Korean Army worked closely with US Army elements and the Army of the Republic of Vietnam in a range of combat actions. This was the first overseas deployment since the Korean defense forces known as ROKA were established. Korean soldiers were trained by American army instructors and the Americans were curious they would perform in the combat arena. Chapter One is a brief history of Vietnam War. Due to special importance of allied forces presence in Vietnam for the theme I describe the Vietnam War history only until 1973. Chapter Two introduces the Korean Army participation through eyes of US Army authorities. The text is mostly based on Larsen and Collins' "Allied Participation In Vietnam". This chapter describes a way that led to official agreements about the Korean participation and a Korean Forces functioning in the South Vietnam combat arena. There are a...

Protection of intellectual property and international law
Trbušková, Jana ; Pítra, Vladimír (advisor) ; Růžička, Michal (referee)
INDUSTRIAL PROPERTY PROTECTION AND INTERNATIONAL LAW The object of the thesis is an overview of contemporary issues in a domain of industrial property and protection given by national and international law. The industrial property contains an extensive category of the industrial property rights. We can divided them into category of rights to results of creative work (patents, utility models, industrial designs) and category of rights to the sign (trademarks and geographical indications). Owing to extensive scope of industrial property the thesis is focused only on a field of the patents and trademarks. The thesis is divided into four main parts. First part deals with statutory regulation of the patents. There are defined requirements of the granting patents for new technical solutions. Furthermore there is described the proceeding of the Industrial property Office and its examination whether the invention complies all requirements of patentability. Thesis describes a system of national protection of inventions that is granted only for the area limited by the state boarder. The thesis is not focused only on protection given by national law but it determines also the present-day international systems of industrial property protection. I mention protection established by Patent Cooperation Treaty that...
