Speculative bubbles in financial markets
Roček, Jindřich ; Brada, Jaroslav (advisor) ; Kubát, Max (referee)
The bachelor thesis explores the phenomenon of speculative bubbles in financial markets. The aim is to define possible causes of speculative bubbles, and specify circumstances under which they can be prevented. The first chapter explains the essence of the examined phenomenon. In the following chapter, two theoretical approaches to the formation of asset prices in markets are explained, the efficient market theory and behavioral finance. The third chapter analyses causes, coarse and collapse of each individual bubble. The work uses twelve samples of asset price bubbles from history to meet the objectives. The final chapter examines the influence of government intervention and monetary policy on the formation of bubbles and proposes stemming recommendations for the responsible authority. The considerable complexity of the phenomenon and a large number of factors influencing price movements means that bubbles cannot be quantified ex ante. Given the current market conditions it is reasonable to expect further occurence of asset price bubbles in financial markets.

Simulated chemical accident associated with the release of phosgene
NOVÁK, Jan
The thesis entitled "Simulated Chemical Accident Associated with Phosgene Leak" focuses on the issue of disasters in general and specifically on chemical disasters associated with leakage of dangerous chemicals. The thesis consists of a theoretical and a practical part. The theoretical part of the thesis is divided into four subchapters. The first subchapter deals with accidents in general, and the classification thereof into natural and anthropogenic contingencies. The subject of the second chapter deals with specification of accidents that occur in the chemical industry. A special focus is given to causes of chemical accidents, among which there are anthropogenic (human factor) and technical causes as well as working conditions and organization of work. As regards classification, chemical accidents are divided into chemical accidents associated with leakage of dangerous chemicals, further accidents with leakage of radioactive substances and those involving oil leaks. With regard to the topic of the thesis, the third subchapter specifically focuses on characteristics of chemical accidents associated with leakage of dangerous chemicals. This is the key part of the theoretical basis of the thesis. The subchapter deals with causes, classification, development, characteristic effects and consequences of such accidents. Factors are also mentioned that affect the spread in the environment of dangerous chemicals leaked as the result of chemical accidents depending on a number of conditions. The fourth subchapter is linked to the preceding chapter in that it provides a brief characteristic of dangerous chemicals. A special focus is given to a comprehensive specification of phosgene. The core of the practical part of the thesis lies in the implementation of research consisting in simulation or modelling of a chemical accident associated with leakage of a selected chemical from a particular chemical plant. For the purpose of modelling phosgene was selected as the dangerous chemical. The company Synthesia, a. s. located in Pardubice, was chosen as the chemical plant in question. The practical part of the thesis aimed at modelling a chemical disaster associated with phosgene leak at Synthesia, a. s. The software tool TerEx, version 2.9.1. was used for simulation. Using this computer program a total of ten contingency scenarios were prepared involving phosgene leaks of different quantities as consequence of a chemical accident at Synthesia, a. s. Another aim of the practical part of the thesis was to assess risks following from the chemical accident. This assessment was made on the basis of the results of the TerEx program in the form of toxic exposure, recommended examination of toxic phosgene concentration within certain distance from the place of leakage, areas of necessary evacuation of the population, and last but not least time dependence of phosgene concentration and accumulated dose within distances of necessary evacuation of the population. The third and also the last aim of the practical part of the thesis was to assess impacts of this potential chemical accident on the health or lives of the population. The results of the modelled chemical accidents involving phosgene leak from Synthesia, a. s. showed that this contingency would especially impact health but not lives of the population. The phosgene concentrations showed only threshold levels (from 10 to 20 mg/m3) that would cause irritation of the eyes and the upper respiratory tract / nasopharynx. Even though the results of the research showed that no serious impacts on the health of the population should occur, the worst possible contingency scenario should always be considered in the event of such chemical accident.

Study of electrolytic influence on organic dye decomposition in the diaphragm discharge in liquids
Davidová, Jaroslava ; Rašková, Zuzana (referee) ; Kozáková, Zdenka (advisor)
This Bachelor thesis is focused on study of chemical and physical influences which are proceed in diaphragm discharge in water solution. These processes could be used in water treatment. If DC non-pulsed voltage is applied, a significant influence of electrolysis must be taken into account. The main goal of this thesis is the estimation of electrolytic contribution to processes in the discharge. Theoretical part describes basic theory about creation of electrical discharges in water and electrolysis with emphasis on processes leading to destruction of organic compounds. Production of reactive particles (radicals, hydrogen peroxide, ozone, etc.) and electrochemical reactions on electrodes mainly belongs among these processes. This part describes analytical method (UV-VIS spectroscopy) which was used for determination of organic dyes concentration as well. Experimental part is oriented to experiment procedure which was carried out in an apparatus with separated anode and cathode area. Separation was made by dielectric diaphragm with a pinhole in the centre. Its initial diameter was 0.25 mm. Electrolytic decomposition was carried out at constant current of 30 mA and supplied power was about 14–32 W. Two Saturn dyes (Direct Blue 106 and Direct Red 79) were selected for experiments. As the decomposition was related to decoloration of the solution, UV-VIS spectroscopy in the range of 350–700 nm was used for determination of dye concentration. Next part focused on results presents various factors which had remarkable effect on decomposition of organic dyes. These factors were: various polarities of electrodes, conductivity and pH of solution, applied power, kind of electrolyte and structure of organic dye. The electrolysis had the significant influence on decomposition of small organic molecules. Decomposition was running mainly in the anode area where so called negative discharge was created. Optimal conditions were set by NaCl electrolyte with concentration providing initial conductivity of 500 S·cm-1. By the NaNO3 electrolyte half decomposition efficiency was achieved and in Na3PO4 electrolyte, the decomposition even didn’t run. The decomposition in the anode area was stimulated by the low pH value, which was decreasing during electrolysis. Generally, higher decomposition was achieved by the discharge than by pure electrolysis but the electrolysis had higher efficiency. In pure electrolysis, high rate of removal can be achieved by the application of a relatively low power. When bigger organic molecules were decomposed, the efficiency was higher by applying the discharge.

Crisis - family break up-from a child 's view
Nevoralová, Monika ; Procházková, Jana (advisor) ; Hadj - Moussová, Zuzana (referee)
This graduation thesis topic is "Crisis- family break up- from a child's view". As the name Prompts, this paper is focused at the crisis in general, at the crisis in family and also? in detail? at the situation of family break up (or divorce) from a child's view. It is without doubt that the family plays a key role in child's development. It is the first community that a child meets in its life and from which it receives main ways of behavior which are necessary for its social existence. At the same time family is also a place, which is predisposed for getting into crises, family crisis is a period of explosive atmosphere and the family is more endangered by break up. At Present, divorce or family break up are widespread in our society. Beside divorce or partners break up a l s o informal family break up exists husbands or partners still live together but their mutual relationship is *i Very conflictful. Therefore it is possible to say that many children are endangered by disadvantageous s»uation in the family. In this work attention is aimed to children behavior during family crises, childrens' ideas about sřlving critical situations and knowledge of supportive measures. Closer attention is also given to children reactions to parents divorce, parents break up, forms of communications between children and...

The endocrine function of adipose tissue and its importance for initiation and development of insulin resistance and diabetes
Haluzík, Michal ; Schreiber, Vratislav (advisor) ; Marešová, Dana (referee) ; Šeda, Ondřej (referee)
Endocrine production of adipose tissue is a very complex process affected by numerous endogenous and exogenous stimuli. Peroxisome proliferator-activated receptors-alpha (PPAR-) are important modulators of metabolic processes which can also affect endocrine function of adipose tissue. Recently, numerous novel factors produced by adipose tissue with important metabolic effects were identified. Some of them can directly bind PPAR receptors. One of the examples of these factors is fatty acid binding protein 4 (FABP4) which can directly bind PPAR receptors and indirectly modify its activation by changing availability of endogenous PPAR ligands -free fatty acids. We hypothesized that the mechanism of action of PPAR receptors to metabolic processes may partially lie in their complex interaction with adipose tissue-derived hormones. The unraveling of these interactions may have important consequences in finding approaches to treat patients with type 2 diabetes mellitus. (...) In summary, our data show an important role for the interplay of PPAR activation and endocrine function of adipose tissue in metabolic regulations which may have important clinical consequences.
