Sediment deposition in reservoir of Nové Heřminovy dam
Kammermayer, Jan ; Šedivý, Jiří (referee) ; Zachoval, Zbyněk (advisor)
The thesis deals with silting of water reservoir Nové Heřminovy. There's describe design of artificial traffic and evaluate its effectiveness. To determine the flow of sediment into the reservoir with use a partially calibrated one-dimensional numerical model of sediment transport with deformation of bed is made in software HEC-RAS. Silting reservoirs is assessment with two methods, the results are compared and describes their limitations. Reservoirs silting evaluates through volume changes in reservoir storage in time.

Laboratory diagnosis of Clostridium difficile
JANDOVÁ, Romana
Clostridium difficile toxin with production is the most common cause of nosocomial enteric infections. It causes inflammatory bowel disease called Clostridium difficile infection (CDI) of varying severity - from trivial diarrhea to life-threatening conditions such as paralytic ileus and toxic megacolon. C.difficile still escapes the attention of the general public and is in the background of other bacteria, such as MRSA. Clostridium difficile is a strictly anaerobic bacterium. It is a gram-positive rod forming an oval subterminal spores. C. difficile can produce two types of toxins - and toxin A (enterotoxin) and toxin B (a cytotoxin). Due to the toxin causes damage of the intestinal epithelium and deeper layers of the bowel wall. Into inflammatory ulceration that cover of the pseudomembrane. Some strains produce more binary toxin, whose exact function is not underwood yet. It is assumed that potentiates the effect of toxins A and B to increase their concentration. To demonstrate the CDI must remove the stool sample into a sterile tube. In the bacteriology workplace in Czech Budweis Hospital is being made direct conclusiveness of antigen and toxin by immuncgromatography method. It is a membrane-enzyme immunoanalysis for the detection of antigen - glutamate dehydrogenase (GDH) and toxin A / B. Negative result excludes GDH with high reliability clostridial infection. For confirmed CDI is considered proof toxigenic strain of C. difficile. This is evident from the result of either immunochromatography which is demonstrated both the antigen and the toxin, or identity of the gene for toxin B by PCR. If you find out in direct detection only positive antigen, the sample is sent for PCR testing to the Laboratory of Molecular Biology and Genetics. Regardless of the outcome of the immunochromatography, the microscopic specimen stained by Gram are being produce from reces. In the case of proven C. difficile toxin is carried anaerobic culture test that takes two days. For identification of accrued bacteria is used latex agglutination. This is a method in which IgG antibodies bound to latex particles specifically bind to the antigens of the cell wall. To identify the bacteria can be also used the VITEK - MS machine that uses a laser ionization method in the presence of the matrix, followed by mass spectrometry. In case of a positive culture findings Clostridium difficile is being from grown culture set sensitivity to antibiotics by E-test and disk diffusion methods For the year 2011 the Department of Bacteriology examined 291 samples of feces. 13,4 % of these samples had positive antigen and toxin in an imunochromatographyc examination; 15,1 % had a positive antigen and negative toxin and 71,5 % were negative. 74 samples was positive in C. difficile toxin. These samples were subsequently conducted to culture examination - 62,2 % were positive. Most positive samples were sent from the infectious department. It has been examined 53,6 % of women and 46.4 % of mens. Percentage of toxigenic strains of both sexes were virtually identical - 25 %. All strains were susceptible to vancomycin and only one strain was resistant to metronidazole.

Analysis of Rail Freight Transport in Europe
Jindrová, Veronika ; Novák, Radek (advisor) ; Zelený, Lubomír (referee)
The aim of the thesis is to analyse the status of the rail freight transport in Europe in the sense of its competitiveness on the transport market. The analysis is based on the identification of main barriers that characterise European rail freight and the extent of technological and legislative harmonisation across Europe. The status of the rail freight transport is also explored on the basis of the volume of goods transported by rail in European countries as well as on the comparison with road transport. In order to get the realistic idea about this issue the thesis focuses also on the main Czech rail carrier, ČD Cargo, a.s. and their realized transportations.

Measurement of Economic Effectiveness of IS/ICT
Čelikovský, Filip ; Maryška, Miloš (advisor) ; Faina, Michal (referee)
The main goal of this thesis is to measure the economic effectiveness of the specific real IS/ICT based on real data, which were provide by the owner of the system. Next goal is to describe how to measure economic effectiveness of IS/ICT, especially based on costs and effects analysis. Complex information about economic effectiveness of IS/ICT issue and also costs and effects analysis of enterprise informatics are made up of knowledge gained by studying professional publications aimed to this and relative topics. Necessary data to measure the economic effectiveness of the chosen IS/ICT was gained by its owner. To reach the main goal, author chose a few commonly used financial indicators and proposed two other metrics. Based on calculations of these indicators and metrics, author estimated that the rated system is economically effective. Author forwarded the results of measurement to the owner of rated system, along with the comment of author. The contribution of this thesis is that shows the universal procedure of economic effectiveness measurement of IS/ITC in clear and complex structure. The thesis can be divided into two logical parts -- the theoretical one and practical one. In the theoretical part, author describes in standalone chapter possibilities in dividing of costs and its identification, severity of this act and also possible ways of the cost evidence. The next chapter speaks about effects of IS/ICT, where author also mention possibilities in dividing of effects, ways of their identification and measurement. This capture also put the accent especially on the hardness of their assignment. The last theoretical chapter imaginarily joins the antecedent chapters because describes a few financial indicators and metrics, suitable for measurement of economic effectiveness of IC/ICT. In that case, this capture speaks about usage data about costs and effects in measurement of economic effectiveness. One whole chapter is devoted to practical part of this thesis, in which author used all defined indicators and metrics from theoretical part and measured the economic effectiveness based on real data. Thus, author used the knowledge from theoretical part in the practical one. The part of measurement is also a discussion of the results.

Calibration and Exact Characterization of Aerosol Deposit colected by SDI Impactor
Havránek, Vladimír
Ion beam analytical methods as PIXE (Particle induced X-ray emission), PIGE (Particle induced gamma-ray emission) and RBS (Rutherford backscattering spectrometry) are frequently used for elemental analysis of different types of atmospheric aerosol samples in a form of aerosol deposits on thin plastic filters or foils (Alfassi and Peisach, 1991, Johansson and Campbell, 1988). An ideal sample for analysis is thin homogeneous aerosol deposit with known deposit area. However in practice such samples are rare. They are often thick (more than limit for thin target approximation i.e. larger then few hundred micrograms per square centimetres), of irregular shape and unknown deposit area. In such conditions all obtained elemental mass results should be corrected for apparent deposit thickness, deposit homogeneity and effective deposit area.
