Tumours caused by professional exposition of chemical, physical and biological factors
Korček, Jozef ; Kneidlová, Monika (advisor)
Tumours caused by professional exposition of chemical, physical and biological factors in Czech Republic in the timeframe from 1996 to 2008 are on a descending curve. Majority of patiens are men. Ionisation energy and radiation was the prime factor among physical factors; coke production gases and aromatic nitro or amino compounds were the leading factors among chemici factors. The influence of biological factors was insignificant. Ionisation energy and radiation and asbestos were the top two causes of tumours which arose from professional exposition to said risk factors. The most common tumour encountered int his timeframe was a tumour of bronchi or lung, followed by mesotheliomas of peritoneum and pleura. According to industrial classification, vast majority of over 70% tumours caused by professional exposition occured within the scope of mining, metallurgy and succeeding industrial processes dealing with ores and thein processing.

Self-assembly and excited energy transfer in bacteriochlorophyll aggregates
Pospíšil, Petr ; Pšenčík, Jakub (advisor) ; Vácha, František (referee)
Bacteriochlorophyll c (BChl c) belongs among photosynthetic pigments. It is found in lightharvesting complexes of green photosynthetic bacteria in the form of self-assembled aggregates. It is possible to prepare BChl c aggregates also in vitro in aqueous solutions, in the presence of certain non-polar molecules (e.g. lipids or carotenoids). In this work, artificial light-harvesting antenna was prepared composed of BChl c and selected azulene derivative. The aggregation of BChl c with azulene enhances the absorption in the near UV region compared to BChl c. Fluorescence spectroscopy was used to study an efficiency of energy transfer from azulene to BChl c. The procedure used was based on fluorencence excitation spectra measurement, and a comparison with absorption 1-T spectra. The measurements were complicated by anomalous fluorencence of azulene, which occurs from the S2 state. Furthermore, the reference diode in the fluorescence spectrometer did not correct properly the signal in the near UV region, where azulene absorbs. The problem was partially solved by preparing the new correction files using selected laser dyes. Excitation spectra demonstrate the presence of the energy transfer from azulene to BChl c, however, it was not yet possible to satisfactorily quantify its efficiency.

Passive houses - importance od certification and recovery of investment
Partlová, Zuzana ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
In the present time, when prices of energy go up continually, we can hear more and more about the topic of energy-cutting. Important role in this sphere performs low-energy development. Passive houses, which are specific type of low energy houses, cut heat demand significantly. It means marked improvement with the view of energy saving, protection of the environment, but also quality of living. There is no doubt that these constructions bring numerous advantages, as evidenced by ever-growing number of passive houses abroad. Nevertheless, in the Czech Republic are very little passive houses. Partial intention of the thesis work is to highlight the importance of certification, which is able to contribute toward expansion of passive houses. The outcome of this part is proposal of the criteria for certification of passive houses in the Czech Republic. Principal aim of my diploma work is to compare passive house to common house in light of capital expenditures and operating costs and information about pay-off period of investment in low-energy buildings. Just matter of economic return is the most important criterion in decision making about construction of house or building.

Measuring of chemical and physical factors in sports halls
Šimůnková, Dita ; Šafránek, Jiří (advisor) ; Turčová, Ivana (referee)
Title: Measuring ofchemical and physical factors in sports halls. Objective: Is comparing of chemical and physical factors in three different sports halls in south Czech, concretely light measuring dust elements (suspended elements fraction MP1o, MP2,5), than temperature measuring and relative humidity measuring and their following comparison with norms. Methods: The lightening was measured by measuring method with Minolta T - 1Omachine. Dust elementr fraction MP 1O and MP 2,5 were measured by " unstraight gravimetric method". Results: On the basics of ascertain facts and after processing results was verified the hypothesis about observing norms in lightening area in all the sports halls. After the processing results ofdust factors measuring, humidity and temperature, I found out, that there have been overlimit in gymnastic hall ZF JČU, where have been measured higher values of suspended elements and temperature. In the sports hall České Budějovice was overlimit in temperature measuring and dust measuring fraction MP 1O, but only in minimal extensity. Sports hall SLŠ doesn't keep the limits norm in dust measuring offraction MPw,MP2,s Keywords: physical factors, chemical factors, light measuring, measuring of dust elements, humidity and temperature in sport hall. 2

Effects of acute starvation and of type 2 diabetes mellitus upon insulin resistance and substrate utilization in obese subjects
Duška, František ; Anděl, Michal (advisor) ; Haluzík, Martin (referee) ; Mourek, Jindřich (referee) ; Stárka, Luboslav (referee)
Very-low calorie diet or even total short-term fasting is widely used in clinical practice in order to improve metabolic compensation of patients with type 2 diabetes mellitus. Although benefits of weight reduction are well proven in T2DM, much less is known about effects of acute starvation, during which the interruption of the afflux of energy substrates is not followed by a major change of body composition. We hypothesize the improvement of insulin effects on glucose metabolism in T2DM as these patients may lack the key metabolic responses which impair insulin sensitivity in lean, non-diabetic subjects. Moreover, we assume according to "thrifty genotype hypothesis" that protein wasting during starvation will be positively related to insulin effects on glucose disposal and negatively related to insulin antilipolytic and antiketogenic effects. In the light of this we designed an observational, prospective, in-hospital study, comparing the effects of 60 hours fast on various aspects of insulin resistance, endocrine regulation and metabolism in 10 patients with T2DM and 10 obese controls without diabetes (OB).
