Image analysis in tribodiagnostics
Machalík, Stanislav ; Stodola,, Jiří (referee) ; Tillová,, Eva (referee) ; Zemčík, Pavel (advisor)
Image analysis of wear particles is a suitable support tool for detail analysis of engine, gear, hydraulic and industrial oils. It allows to obtain information not only of basic parameters of abrasion particles but also data that would be very difficult to obtain using classical ways of evaluation. Based on the analysis of morphological or image characteristics of particles, the progress of wearing the machine parts out can be followed and, as a result, possible breakdown of the engine can be prevented or the optimum period for changing the oil can be determined. The aim of this paper is to explore the possibilities of using the image analysis combined with the method of analytical ferrography and suggest a tool for automated particle classification. Current methods of wear particle analysis are derived from the evaluation that does not offer an exact idea of processes that take place between the friction surfaces in the engine system. The work is based upon the method of analytical ferrography which allows to evaluate the state of the machine. The benefit of use of classifiers defined in this wirk is the possibility of automated evaluation of analytical ferrography outputs; the use of them eliminates the crucial disadvantage of ferrographical analysis which is its dependence on the subjective evaluation done by the expert who performs the analysis. Classifiers are defined as a result of using the methods of machine learning. Based on an extensive database of particles that was created in the first part of the work, the classifiers were trained as a result, they make the evaluation of ferrographically separated abrasion particles from oils taken from lubricated systems possible. In the next stage, experiments were carried out and optimum classifier settings were determined based on the results of the experiments.

How to prevent the proliferation of Legionella pneumophylis in hot water in the hospital Czech Krumlov
TUREK, Jan
This diploma thesis deals with microbiological quality of hot water in a hospital in Cesky Krumlov as well as hot water piping condition with respect to Legionella. It also deals with arrangements for improving the quality of hot water in this hospital. The subject and target of this thesis are the findings of the mentioned parameters based on own observations, technical documentation and analysis of warm water performed by an accredited laboratory. The hospital in Cesky Krumlov, the construction of which began in 1909, was built in 1911 as the 'Nemocnice Císaře Františka Josefa I.' As the time went by, new buildings were built up. The hospital was renamed to 'Všeobecná veřejná nemocnice' in 1942. In the following years the hospital expanded until the current condition. Water quality and presence of Legionella is a world-wide issue, which we must fight against. The thesis is divided into two parts. First, theoretical part, which includes both general and specific knowledge about Legionella, its health risks, the environment in which it occurs, possibilities of eliminating, suitability of the material for hot water pipes, gained in professional literature and a part of the Czech legislation dealing with public health protection, the law 'No. 258/2004 Coll.' in actual version and quality of drinking water and hot water. In the second, empirical part, I focus on the situation of the hospital in Cesky Krumlov from 2009 till 2015, concerning newly built boiler room and the whole distribution system of hot water regarding Legionella. Particularly I focused on materials used for ecologisation of the gas boiler room and materials used for hot water pipes and actual state of water distribution in individual buildings of this health care facility. I mentioned the analysis of the water samples performed by an accredited laboratory with corresponding technical documentation, which concerns the water distribution system, provided by the medical facility. I used secondary data analysis to evaluate these documents. Regarding the results from 2009 to 2015 the microbiological quality of warm water doesn't meet the limits defined in the Attachment No. 3 of the above mentioned law Order 252/2004 Coll. Limit value for colony forming units of Legionella is set to maximum of 100 CFU. In most of the samples this limit was exceeded by series of units up to hundred thousands of units. The last results in 2015 prove improvement of the unfavorable situation. In that year the analysis was tested three times. First in February, where the CFU units were 'only' in hundreds, with the top value of 550 CFU in the Postacute Care ward. Second analysis was performed in June that same year. Results were acceptable. The highest value was 64 CFU. Last analysis in the hospital was performed in December. Increased concentration of Legionella was again in the Surgery building. There were established of 1400 colony forming units. There were 300 CFU in the Postacute Care ward and the limit value of 100 CFU was in the ward of Internal medicine. The answers to research questions 'How to prevent reproduction of Legionella peumophylis in the water distribution system of the hospital in Cesky Krumlov?' and 'How to ensure a sufficient amount of quality hot water in the medical facility?' are included at the end of the stated recommendations. A risk factor causing the fast reproduction of Legionella is the old water distribution system in most of the buildings and low water temperature of water leaving the boiler, which is 55°C. All mentioned results and evaluations are included in this thesis as well as attached pictures, which show the environment and situation within the Health Care Institutions.

Factors affecting postmortem changes in pork meat
Seilerová, Michaela ; Čítek, Jaroslav (advisor) ; Lebedová, Nicole (referee)
The thesis focused on the summary of the quality of pork. The main indicators of the quality of pork and of meat generally together with a chemical composition and the external and internal factors dealing with the quality of meat are described in the thesis. The various histological structure, the variable chemical content, technological features are found in meat. The structure and composition depends on a way of living, the function of the parts of an animal body, on lots of intravital factors (a kind of an animal, breed, male or female, age, the way of nutrition, the state of health). Meat is a valuable source of nutrients and essential acids for a man. The human organism is not able to synthesize the essential acids itself. Lipids are the important part of meat, their main function is storing energy. They are found as a reserve tissue in the subcutaneus parts of animals or among muscular fibre. The amount of carbohydrates contained in meat is not important, meat is low in carbohydrates. They are only important for meat maturation. Meat is high in minerals and vitamins. It is necesary for a man and should be a part of our diet. The important factor for a meat quality is described as a formation of muscular fibres. There are the thin fibres in the meat of a high quality and the thick and fat fibres in the meat of a low quality. The meat quality depends on a number and charactes of animal fibres. The meat of a high quality is for example loin - it is the meat with fine fibres. The next factor which has influence on a meat quality is course of post mortem changes.We can differentiate four stages in these processes: prae rigor, rigor mortis, aging of the meat and deep autolysis. Post mortem aiging processes can deviate from teh standard from variety of reasons and as concequences we can see quality deviation of the meat for example PSE, DFD, RSE, Hampshire efect and cold shortening.Also the breed has the influance on the quality of the meat namely sensitivity to stress,growth characteristic and parameters of slaughter value, other internal factors are age and sex. External factors which has the influance on the quality of the meat are transport of the animals to the slaughterhouse, attitude of the employees during chasing after the animals, the rest before slaughter, stunning itself,bleeding thereafter and cooling down after slaughtery.
