Influence of different types of slaughter lines for the incidence of pork meat (PSE)
ČERNÁ, Lenka
The main aim of the present thesis was to compare different types of slaughter lines and their influence on the occurence of meat defects with emphasis on PSE defect. The research has been concentrated mainly on the slaughter lines which use the technology of stunning the animals with electricity and concentrated CO2. The research monitors the rate of PSE defect from the slaughter to the cutting of the pig (approximately 48 hours). For considering the difference in quality of the meat the basic identification indicators of both pH1 and the draining of meat were created. Furthermore, we monitored pH24 and pH48, too. Analyzing of the above mentioned indicators shows that stunning with concentrated CO2 is more suitable with regard to the quality of the meat. The average pH1 value was 0,3 (p < 0,001) higher, pH24 value was 0,243 (p < 0,001) higher and the average value of meat juice drainage was 2,16% lower (p < 0,001). The anylysis of the PSEi and PSE quality difference based on pH1 when stunning with the use of concentrated CO2 shows lower frequency of PSEi (7,843% lower) and PSE (1,961% lower). Based on meat juice drainage, PSEi frequency was 23,810% lower and PSE 4,762 % lower.

PSE-Defect - Quality Impact During 48 Hours After Slaughtering
PUDIVÍTR, Aleš
Comparison of pig?s stunning (by electricity or CO2) at slaughterhouse and monitoring the occurrence of quality variance PSE during 48 hours post mortem was main goal of this work. Basic indicators such as pH1, drip loss of water and meat colour (lightness) were determined to assess PSE. In addition to these indicators have been also evaluated values of pH24 and pH48. The result of those indicators is that during stunning by CO2 gas value of pH1 was higher by 0,3 degree (P < 0,001), value of pH24 was higher by 0,243 (P < 0,001) and average drip loss of water was lower by 2,16 % (P < 0,001). Changes in other evaluated indicators were statistically non-significant. Occurrence of quality variance which tends to PSE (PSEi) and PSE was evaluated at slaughterhouse which is using electricity for stunning as higher by 7,843 % at PSEi and 1,961 % at PSE based on value of pH1. As higher was evaluated also drip loss of water by 23,810 % at PSEi respectively 4,762% at PSE. Difference between occurring of PSEi and PSE based on meat colour was not observed. The highest correlation dependence was found between pH1 and drip loss of water (r = 0,586, R2 = 34,315 %).

Evaluation meat quality in depading on condition of transfer
ČONDLOVÁ, Šárka
Work deals with transport of animals for slaughter and its influence on the quality of meat. Summarizes the right ways of loading, unloading and manipulating with animals. Determinates the precise requirements for the means of transport and transport equipment. Includes the most used transportation by road and marginally used transport by rail and water. Mentions the most common causes of injuries, deaths and losses during transport. Points to the influence of manipulations with animals on the quality of the meat. The result of improper treatment of animals are meat defects DFD and PSE, witch are commonly caused by stress and exhaustion of energy reserves. Describes the basic defects of meat of slaughtered animals-bovine animals and pigs. Mentions the basic laboratory techniques for the detection of these abnormalities.

Stock markets regulation - chosen regulations impact on stock market
Kecl, Michal ; Jílek, Josef (advisor) ; Munzi, Tomáš (referee)
The thesis is focused on state interventions and regulation on field of stock exchanges. On special examples I show for and against argumentation of real precautions. I repeal the questions of public konvenience of these precautions. In the first part of the thesis I begin with historical genesis of exchange especially in our area including the origin -- private or state. The first part continue with theoretical functions of stock exchange and its fulfilment in case of The Stock Exchange in Prague. In the second part I present dilemma of squeeze-out or expropriation of minority shareholders.There will be arguments of proposers, opponents and also neutral arbiter representing by The Constitutional Court of the Czech Republic. In the third part of the thesis I present an example of foreign regulation. It is Sarbanes-Oxley Act with its impact on different entities. In conclusion I propose some changes and I want to give a support to discussion about state admission to regulation of stock markets.

Cenné papíry
Minář, Jan ; Hnilica, Jiří (advisor) ; Smrčka, Luboš (referee)
The Comparison of the Czech and American Private Stock Investor predominantly by means of global part of fundamental analysis in 1994 ? 2008 period. Theoretical part compares the history of both markets, its major stock exchanges and trading-related information. Practical part provides a detailed analysis of these markets followed by discussion about returns, liquidity, risk, intermediaries and other factors influencing investment decisions.
