Does .i.Histoplasma capsulatum./i. occur in caves of middle Europe?
Nováková, Alena ; Chroňáková, Alica
During studies of micromycetes in several caves (Slovakia - NP Slovak Karst, Czech Republic), white-yellow to yellow coloured microfungal colonies on bat droppings are observed. Tuberculate conidia were estimated in microscopic slides prepared from these colonies. These conidia reminded with their size, shape, surface structures and type of conidiogenesis pathogenous micromycete fungus .i.Histoplasma capsulatum./i.. This micromycete species occurs on bat guano in warmer regions of the world. In Europe, this fungus was recorded from Italian caves and soils and it was also reported from Romania, but without the evidence of thermal dimorphism. After repeteadly isolations, two strains of this fungus were isolated from Slovak caves (Domica Cave and Jasovská Cave). Tests of pathogenity (intranasal and intraperitoneal application to SCID mouses) and of the evidence of thermal dimorphism were negative.

Čukat, Stanislav ; Kolbábek, Antonín (referee) ; Charvát, Pavel (advisor)
The master’s thesis deals with the design of solar assisted space heating and domestic hot water (DHW) heating in a detached single family dwelling. The thesis contains the heating load calculations as well as the calculation of the energy consumption for space and DHW heating. The thesis also contains the actual design and sizing of the heating system including the drawings. A simulation of solar heating was carried out with the use of the TRNSYS simulation tool in order to assess the yield of the solar heating system.

Morphometric analysis of sex differences of chameleon \kur{Rhampholeon brevicaudatus}
VIK, Daniel
In recent years, it is becoming a very popular breed of so-called dwarf chameleons ( Brookesia genera , Rhampholeon and Rieppeleon ), especially for their size and also very interesting look that is the exact opposite of big colorful chameleons ( genus Furcifer ) . The most common species from these dwarfs chameleons is Rhampholeon brevicaudatus A major challenge for most breeders , however, the sex determination in these dwarf chameleons . This work aims to bring the issue of sexual dimorphism in these dwarf chameleons. Sexual dimorphism in these chameleon show to a longer and wider tail males due reproduction organs in hemipenes pockets. These hemipenes pockets are clearly visible. Among other differences identified are longer, wider and taller head of males and long bones of the limbs, as humerus and femur of males.

Sexual size dimorphism in medieval period in Bohemia.
Kaupová, Sylva ; Brůžek, Jaroslav (advisor) ; Dobisíková, Miluše (referee)
Differences in height among human populations or changes in height over time may be associated with different degrees of sexual dimorphism in this feature. This thesis compared the height and sexual size dimorphism (SSD) between two groups of the population of Medieval Bohemia - rural residents and inhabitants of Prague. A sample of 179 adult skeletons from five Prague sites and 175 individuals from four rural sites, dating from the 11th to 14th century, was used. Sex was determined following the principle of primary and secondary sex diagnosis, which enabled the derivation of population-specific discriminant functions using the dimensions of the humerus, femur, tibia and talus. A subsequent analysis of body height did not show statistically significant differences either in height or in SSD between the Prague and the rural part of the population of Medieval Bohemia, despite the major changes which Czech Medieval society went through in the 13th century. Comparing our results with previously published data on the height of the Czech population during the early modern period indicates a statistically significant reduction in the magnitude of sexual size dimorphism in the population of the17th century, particularly associated with a decrease in the height of men. A significantly higher stature of...

Health and social risks in children predisposed to metabolic syndrome
SLADKÁ, Alena
Metabolic syndrome was defined for the first time in 1988 by Reaven, who defined it as a hormonal-metabolic syndrome - with symptoms of resistance to insulin , hyperinzulinismus, hypertension and with laboratory-proven higher level of lipoproteid VLDL and lower level of HDL and LDL cholesterol. Obese children have big troubles concerning social relationships. Overweight children are often an object of ridicule, teasing, verbal bullying, physical bullying, cyberbullying and sexual abuse. First goal of this thesis is to find out, whether obesity (mainly of android type) in children and adolescents (aged 10-18) having BMI higher than 28 and waist size for boys over 103 and for girls over 93, overall cholesterol level over 6,5, blood pressure higher than 130/70 are predispositions of manifestation of MS in adulthood and to find out what are the social and health impacts of the obesity in the childhood. Second goal of this thesis is to find out, whether patients with metabolic syndrome (MS) had predispositions for obesity or were obese in the childhood and what are the health and social impacts of MS in their life. The first research group consisted of ten children aged 10-18 with predispositions to manifestation of MS. Methods of accomplishing goals of this thesis: Survey of health and family anamnesis. All ten children aged 10-18 were repeatedly checked during six mounths for their body weight, waist size, blood pressure and cholesterol. Surveyed values are shown in the table. I Used a structured interview to survey relationships of obese ones with same-age children, whether they are an object of ridicule and bullying and what are other troubles caused by the disease. At the same time I gave questionnaires to parents to ascertain the eating habits and life style of the family. Health and social impacts for life of people with diagnosed MS, when they were diagnosed MS and their childhood condition were examined using structured interviews in the metabolic advice centre. The research group consisted of ten patiensts of metabolic advice centre. After analysis of data and health anamnesis it was proven that 60% of researched children suffer from higher morbidity (breathing issues, upper respiratory tract infection, and easier fatigue during physical exertion). 60% of children have serious issues to establish relationships and suffer from verbal and physical bullying. 40% of adult patients of metabolic advice centre had troubles with obesity already in their childhood. All of them suffer from type 1 diabetes. Two of them recieve disability pension due to MS. 90% of them told, that they regulary go see a doctor und regulary take cures. These facts cause worse financial situation (lower income, expenses for cures and travel to a doctor). Two respondents mentioned discriminating behaviour of medical staff, however they didn't mention the type of discrimination. According to the questionaries only one person considers the MS is caused by his lifestyle. Research group consisted all the time of ten children and ten adults with MS, because 'Snowball sampling' research methods didn't survey any new facts, which would be needed to verify.

Analysis of the factors leading households in Mělník area to use environmentally thrifty type of heating
Mužíková, Hana ; Louda, Jiří (advisor) ; Malý, Vítězslav (referee)
The aim of this thesis is to indentify the determinants which influence households in selection of type of heating. The survey realized as a structured personal interview with the representatives of 70 households in Mělník -- Chloumek area, provides the information about the factors influencing respondents in selection of type of heating. Through multiple regression analysis was proved that the main factors are age, level of education, household income in total and size of dwelling. However these predictors are statistically quite insignificant. For more significant results it should be analyzed larger dataset.

The effect of nest quality for breeding success in Great Reed Warbler
Jelínek, Václav ; Procházka, Petr (advisor) ; Fuchs, Roman (referee)
Nests are key structures for the reproduction of majority of avian species and as such they should be subject to natural selection. Six hypotheses have been suggested to explain variance in avian nest size. In my master thesis I evaluate their validity in the Great Reed Warbler (Acrocephalus arundinaceus). First two hypotheses describe responses of nest size to predation and brood parasitism. These two selection pressures may lead to the reduction of nest size, but no evidence of their impact on nest dimensions was obtained. However, I found a significant but negative relationship between the probability of nest predation and soft nest height. No such relationship was found between the probability of brood parasitism and nest size characteristics. The incidence of brood parasitism was affected only by nest visibility from the nearest cuckoo perch site and distance from open water. More visible nests suffered heavier parasitism while those located deeper in reed beds were better protected from cuckoo parasitism. Another four hypotheses describe selection pressures which favour large nests or some of their functional parts. The thermoregulatory hypothesis, the sexual display hypothesis and the nest support hypothesis did not explain nest size variation. I found support for the clutch size hypothesis,...

Study of sintering of advanced ceramic materials
Stromský, Tomáš ; Hadraba, Hynek (referee) ; Maca, Karel (advisor)
The influence of various pressure-less heating schedules (CRH - Constant Rate of Heating, TSS - Two Step Sintering, RCS – Rate Controlled Sintering) on the final microstructure of cubic zirconia ceramics was studied in this master´s thesis. There were used nanopowders ZrO2 (stabilized with 8 mol.% Y2O3) with initial particle size 80 nm (TZ-8Y) and 140 nm (TZ-8YSB). Powders were cold isostatically pressed and pressure-less sintered in air by different heating regimes. It was found that for both studied materials the modification of conventional sintering (CRH) using lower sintering temperatures and longer sintering dwell times can result in samples with finer microstructure. For example, the sintering of TZ-8YSB ceramics at a relatively low temperature (1270 °C) but for very long time (60 h) led to ceramics with the same final density (99,25 % of theoretical density) and almost identical grains (1,31 m vs. 1,27 m) in compare with TSS (1440 °C/ 1290 °C/ 15 h). On the other hand, RCS method showed no positive effect on the microstructure of both materials in comparison with CRH method. The obtained results indicate that the microstructure of c-ZrO2 ceramics can be influenced rather in its third sintering stage (by CRH and TSS methods) than in the second sintering stage (by RCS method).
