Changes in structure and phase composition in the surface of tram rail
Švábenská, Eva ; Roupcová, Pavla ; Schneeweiss, Oldřich
We have investigated structure and phase composition of surface layer of tram rails after long time running and the results were compared with those obtained on the original part of material. Changes due to effects of severe plastic deformation together with thermal shocks by friction process were expected. The information about structure and phase composition was obtained by optical and scanning electron microscopy, X-Ray Powder Diffraction, Mössbauer Spectroscopy and Glow Discharge Emission Spectroscopy (GDOES) and this was completed by microhardness measurements. The results show that the surface layer in comparison with the original material exhibits important changes in grain structure, an increase in microhardness and high content of iron oxide and hydrooxides. According to the depth profile of the chemical composition measured by GDOES there is an increase in carbon content in the surface layer which can be effect of up-hill diffusion.

Organization of the protest action against Hus's burning at the stake
Novotný, Robert
Based on a prosopographical analysis, the study attempts to capture the organizational context of the origin of the protest letter against Hus's burning at the stake from 2 September 1415. One of the main conclusions is that the majority of the signatories from the ranks of the lower nobility added their seals to the protest action rather from loyalty to their powerful neighbours than expressing their own confessional position.

Schizophrenia: Impact on quality of life
Konopásková, Veronika ; Ondrušová, Jiřina (advisor) ; Nová, Monika (referee)
Veronika Konopásková Schizophrenia: Impact on quality of life Annotation The goal of the thesis is to understand the impact of schizophrenia on quality of life of the patient. Schizophrenia is defined and its most common forms and symptoms are presented. I describe the origin, course and prognosis of the disease. I focus on the concept of relapse and suicide risk in patients with schizophrenia. Treatise on the treatment is divided into psychosocial and biological methods. I deal with the concept of Quality of life in general and in connection with schizophrenia. I discuss the problem of stigmatization of the mentally ill patients. The example of three selected organizations (Baobab, ESET-HELP, DPS "Ondřejov") illustrates the wide range of psychosocial rehabilitation programs offered for mentally ill. To capture authentically all aspects of life with schizophrenia, I conducted three in-depth interviews with persons diagnosed with schizophrenia. Key words: In-Depth interview, Mentally ill, Psychosocial rehabilitation, Quality of life, Relapse, Schizophrenia, Stigmatization, Suicide Summary My thesis deals with the impact of schizophrenia on quality of life. The concept of schizophrenia, its forms, symptoms, origin, course and prognosis were presented. I focused on the concept of relapse and suicide risk in...

Scream and Silence
Štefaňák, Ondřej ; NEBESKÝ, Jan (advisor) ; KORČÁK, Jakub (referee)
The work aims to examine the artistic expressionist tendency, manifested in expressionist drama and theater practice. In the first part, the author focuses on the origin and the direction of its general manifestations in arts and the historical context of expressionism. The author also attempts to highlight the features of expressionism in drama and contemplates the methods of expressionist artists in theater. In the second part, the author reflects his own experience of the production of an early expressionist text ''Spring’s Awakening''. He analyzes the text's dramaturgical potential and creates the basis for the theatrical production. He describes the creation of the staging as an audio-visual and scenic solution, where the particular focus is on the stylization of actors. Finally, the author tries to capture the essence of expressionism in a broader sense, as a peculiar way of expression for the artist.

Determination of content substances for selected species and varieties of roses.
Slavíková, Eva ; Sus, Josef (advisor) ; Súkeníková, Tereza (referee)
This bachelor's work is focused on comparing the most significant content substance, vitamin C, in fruits of chosen rose kinds species and varieties. Herbal products are often seen by people as products of "second choice", when failure of allopathic treatment occurs, which is focused especially on suppressing symptoms of illness, but it ignores health of the human body as whole. That's why are herbal products often alternative for therapy of chronic diseases. The base of this work is extensive literary research and results of laboratory measurings. Literary part of this work includes description of botanical classification of rose plants. There is stated basic characteristic of individual rose species and their morphological features. In following chapters is composed overview of effective substances in rose fruits and their effect on human health. In practical part of this work are included results of laboratory tests for determining ascorbic acid content for chosen samples of rose species and it also includes results of weighing and measuring of fruit samples of chosen rose species. There are also stated chosen rose species and shortly their origin and description, in the beginning of practical part. For practical part were chosen samples of species. Results of practical part are compiled into statistic tables and graphs and it confirms high content of ascorbic acid in rose fruits. This content is in range of cca 300 - 900 mg.100 g-1. Due to growing interest in alternative treatment options and "clean" natural product, it can be assumed, that many plants of Rosaceae family will keep its place in treatment practice. Those plants will be used not only for treatment of acute and chronic diseases, but also for cosmetic products production, thanks to its large effects and process options.

Population genetic analysis of Old Kladruber horse
Vostrá Vydrová, Hana ; Majzlík, Ivan (advisor) ; Karel, Karel (referee)
The Old Kladruber horse, along with the Lipizzaner horse, Andalusian horse and Lusitano horse, is of the original Italo-Spanish type. The Old Kladruber horse is kept in two colour varieties (grey and black). Because the population is closed, there is a concern about the loss of genetic variation. The genetic diversity and population structure were analysed in the Old Kladruber horse breed based on the pedigree information of animals that were registered in the Studbook to identify factors that may have affected the genetic variability of the breed. Pedigree records collected from 1729 to 2013 contained information on 7971 animals that were used in the analyses. The pedigree depth was up to 33 generations, with an average of 15.1 complete generations. The effective number of founders and ancestors contributing to the current genetic pool was 92.69 and 17.16, respectively. The average values of the inbreeding coefficient were as follows: 13% (with a maximum value of 29%) for the reference population (individuals that can currently take part in reproduction, n=612), 11% for the grey variety (with a maximum value of 25%) and 15% for the black variety (with a maximum value of 29%). The proportion of inbred animals was high (99%). The average rate of inbreeding in the reference population was 1%: 0.8% for the grey variety and 1.1% for the black variety, and the respective estimates of the effective population sizes were 52 for the reference population, 62 for the grey variety and 45 for the black variety. The estimated percentage of genetic diversity lost due to non-random mating within subpopulations and the reference population was 1.0, 1.0 and 1.2%, respectively. The total loss of genetic diversity in the reference population, in the grey variety and in the black variety was 11%, 13% and 17%, respectively.

Microbiota of the digestive tract of bees and related insect and the influencing facftors
Hroncová, Zuzana ; Havlík, Jaroslav (advisor) ; Kalous, Lukáš (referee)
This thesis consists of six research chapters, out of which, five have already been published in research journals, 1 is in the process of submission and the last chapter presents original unpublished confidential data in the process of manuscript preparation.
The research presented in this thesis concerns the complex mechanisms of bees and wasps immune system focused on microbiota as component of immunity. As shown in the introduction, highly social and managed species of bees like honey bees and bumble bees, play key roles in natural and agricultural ecosystems worldwide. Recent losses of bees have been attributed to pesticide exposure, poor nutrition, increased parasite loads and habitat degradation. Over the past several years, governments, beekeepers, and the general public worldwide have become concerned by increased losses of honey bee colonies, calling for more research on how to keep colonies healthy. Our main aim was to explore the complex mechanisms of bees and related species gut bacterial populations, their links to insect immunity and investigate the opportunities for an intervention. Part of our aim was to characterise the bumble bee and wasp gut microbiota using 16S RNA sequencing in a search for potentially novel bacterial species.
We have tried to explain how microbiome interacts with the host and showed that major members of these communities appear to benefit the host. The simple gut communities of social bees present ideal model systems to investigate the underlying evolutionary and genetic processes of such interactions. Information based on our results may help in the design of proper probiotic supplementation strategies with respect to physiological conditions in the honey bee gut.
