Radiation-induced cancer in the population of villages around MAPE Mydlovary
KREJČÍ, Klára
In 1959, the building of chemical preparation plant of uranium ore MAPE Mydlovary was initiated in a small village Mydlovary, near České Budějovice. In October 1962, the operation and processing of the uranium ore started. During operation, about 17 million tons of uranium ore were processed and the material from processed uranium ores was stored into the contiguous sludge lagoons. The operation of this plant was terminated in November 1991. The premises of MAPE Mydlovary were partially liquidated, decontaminated and handed over for privatization, nowadays there are recovery and reclamation works in process. Even though, MAPE Mydlovary is nowadays one of the most dangerous strains for environment, which emerged after mining and processing of uranium ores in the Czech Republic. The projection is to liquidate the consequences of this process for many more years from now. In immediate closeness to the premises of MAPE Mydlovary there lie the villages Mydlovary, Olešník and Zahájí. It can be assumed that during the processing of uranium ores and subsequent storing of waste into the contiguous sludge lagoons there could have been some impact on the inhabitants of these villages by radio nuclides. The possibility that there are still some sources of contamination and effect on the inhabitants of the three neighboring villages cannot be excluded nowadays, even after almost 23 years after the shutdown of the plant. For this reason this diploma thesis is dealing with the effects of the preparation plant MAPE Mydlovary on the inhabitants of Mydlovary, Olešník and Zahájí, specifically on the amount of deaths due to cancer diseases of inhabitants of these villages. Data was collected from October 2013 till April 2014 and it includes figures from the period 1971-2010. It was collected using non-standardized interviews and was provided by practicing physicians of the investigated villages; furthermore, data was collected from websites of the Czech Statistical Office. Aim of this thesis was to analyze and compare the deaths due to cancer diseases of the inhabitants in the surroundings of MAPE Mydlovary and of inhabitants in the whole Czech Republic (whole republic´s cancer disease mortality) and evaluate the possible influence of the radiation load on the number of deaths due to cancer diseases of inhabitants in the surroundings of MAPE Mydlovary. The analysis and comparison of the number of deaths was carried out using statistical research. Non parametric testing was used for the statistical research and the so called Fisher exact test was used, which is carried out by means of statistical software www.ncss.com. For this test the level of significance - = 0, 2 was used. The influence of the radiation load on the number of deaths due to cancer diseases is statistically significant only in the village Mydlovary, where it is possible to prove statistically an increased number of deaths due to cancer diseases in comparison to the number of deaths due to cancer diseases in the whole Czech Republic. Based on the evaluation of the obtained data we can state that the chemical preparation plant of uranium ore MAPE Mydlovary most likely had and still may have a negative impact on the inhabitants of the neighboring villages, especially on the inhabitants of the village Mydlovary. For this reason it is very important to continue with the recovery and reclamation works in the premises of the chemical preparation plant of uranium ore MAPE Mydlovary and their main objective is to protect the inhabitants of surrounding villages against possible exposure to the radio nuclides. Nevertheless, the impacts of processing the former chemical preparation plant of uranium ore MAPE Mydlovary will be eliminated for many more years.

Origin, degeneration and detection of sex chromosomes
Jílková, Klára ; Král, Jiří (advisor) ; Kratochvíl, Lukáš (referee)
Sex chromosomes evolved from a pair of autosomes and they are differentiated as a result of supression of recombination. This process leads to a successive degradation of odd sex chromosome (alosome), which is becoming genetically inert finally or even excluded. Fundamental processes taking part in degeneration of alosome are Muller's ratchet, genetic hitchhiking, background selection, accumulation of transposable elements and constitutive heterochromatin. Indeed, these processes take part in either degeneration of both Y or W chromosomes. Remarkably, these alosomes show different rates of degeneration, most probably due to 1) different structure of male and female gonads as well as 2) different course of gametogenesis in both sexes. Furthermore, rate of alosome degeneration is usually lower in plants because they are haploid during the major part of life cycle. Other mechanisms of sex chromosome evolution involve rearrangements between autosomes and gonosomes, nondisjunctions and fissions of original sex chromosomes, transformation of B chromosomes into sex chromosomes or non-random segregation of autosomes with sex chromosomes. Other phenomenon that appears in sex chromosome evolution is transition between XY/XX and ZW/ZZ systems or transition between chromosomal sex determination and epigamy. Actually,...

Implementation of methods of critical thinking in teaching photosynthesis
Beránková, Tereza ; Čížková, Věra (advisor) ; Novotný, Petr (referee)
This study discuss two phenomenones. The first phenomenon is photosynthesis; this process played a key role in the emergence of life and is necessary to maintain a various life on our Earth. Photosynthesis enables plants to use a bottomless supply of solar energy to produce organic substance and release oxygen. The second phenomenon is critical thinking; the ability to sort and evaluate new information and form "your" own opinion indispensable ability for modern human. In a theoretical part of the study is dealt with term critical thinking, teaching methods of critical thinking and photosynthesis of biological and didactic point of view. In a practical part of the study is dealt with compilation and verification materials for thematic unit of photosynthesis, which would lead to the development of critical thinking of high school pupils (students). Furthermore in the practical part is a questionnaire survey, which is evaluated existing using of methods of critical thinking at biology teachers at high schools and is analyzed their teaching methods to the topic of photosynthesis. In the study is dealt with processing the topic of photosynthesis in selected high school textbooks.
