Effect of evening primrose oil om selected physiological parameters of thoroughbred horses under training conditions
Mikešová, Kateřina ; Hučko, Boris (advisor) ; Václav, Václav (referee)
Physical exercise increases tissue demand for oxygen and cell respiration, resulting in the generation of free radicals and reactive oxygen species. Overproduction of oxidants exceeding the cellular antioxidant capacity results in oxidative stress. Oxidative stress leads to tissue damage of a wide range of biomolecules and causes metabolic changes that consequently influence performance. To protect against oxidative stress, the body has an effective antioxidant defence system, including non-enzymatic and enzymatic components. The antioxidative effect of evening primrose oil (EPO) administration on the oxidative stress of race horses during their regular training period was determined. The eight-week experiment was performed on ten clinically healthy thoroughbred horses. All the horses were enrolled in a regular training program. Eight weeks before the experiment, the horses were fed a diet which remained the same for the following eight weeks, only supplemented with 150 ml EPO (blood samplings 3 times). Total antioxidant reactivity, thiobarbituric acid reacting substances, uric acid, levels, activities of muscle enzymes, eg. aspartate aminotransferase, creatine kinase, and parameters of fatty acid metabolism such as triacylglycerols and nonesterified fatty acids were determined. Average values of TAS after supplementation with EPO rose gradually and were detected at significantly higher levels in the sixth week in comparison with the control. The concentration of malondialdehyde, measured as TBARS, decreased significantly compared with the untreated control. The activities of AST and CK fluctuated, but no disturbance was demonstrated in muscle homeostasis. The present results indicate that the total antioxidant activity of the thoroughbred horses fed a diet supplemented with EPO was higher, and it helped stabilize the permeability of the muscle cell membranes in the horses at full workload.

Factors affecting the nitrogen compounds removal process in specific types of wastewater
Radechovský, Josef ; Balík, Jiří (advisor)
Abstract:
This work summarizes the current knowledge about removing of nitrogen compounds from wastewater using non-traditional biological methods. They include for example process of nitritation/denitritation and a process of deammonification. Special innovative biological methods are economically advantageous because of savings of oxygen for the oxidation of N-ammon and organic substrate for the formation of N2.
Achieving of accumulation of nitrites (achieving of shortcut nitrification) due to suppression of nitrite oxidising bacteria (NOB) is the basis of methods mentioned above. Stable shortcut nitrification is influenced by many factors and achieving of this process in a low-strength wastewater is still problematic, so some new procedures how to optimize it are investigated. This was also the main aim of research that was realized at the Department of Agroenvironmental Chemistry and Plant Nutrition of the Czech university of Life Sciences in Prague.

Education and gender - causes, relationship and possible solutions to the issue of gender inequality
Kubištová, Markéta ; Sycha, Martin (referee) ; Beneš, Milan (advisor)
The subject matter of this paper is searching for relations established between one's biological sex, gender (the social construction of sex) and position in the society. It discovers the causes and correlations of unequal attitude towards men and women, as well as it attempts at finding possible solutions of the issue by means of education. The first chapter explains the basic terms and relations between them, the creation of human biological sex and establishment of gender. The term is explained as socially conditioned cultural differences between men and women. The chapter also states certain theoretical standpoints clarifying gender construction, in particular the process of socialization of an individual, during which the person's gender is created. The aim of the second chapter is to describe the role of educational institutions and the system of education in establishing and maintaining social inequalities. It explains the mechanisms of schools contributing to socialization of a person, with a special emphasis on creating, or supporting gender identity of a child. The work of teachers and their attitude to pupils is an important aspect supporting the traditional perception of gender roles. The purpose of the third chapter is to define the scope of education of adults, its basic principles, goals and...

The effect of the stockperson on the behaviour of cattle
Janská, Jaroslava ; Chaloupková, Helena (advisor) ; Valníčková, Barbora (referee)
The thesis is focused on influence of keepers on cattle and it is pointing out the importance of cattles welfare that has also influence on economy of cattle breeding which is for keeper very important.
The concept of animals welfare is explained in the first part of thesis, because we can consider this concept to be the key concept and it occurs in every part of this thesis.
Following part is devoted to changes that cattle breeding have been facing recently. The changes are thanks to the shift in performance and thanks to modification of keepers, carers and customers ways of thinking. Doležal and Staněk (2015) point out so called breeding complex:
1. Breed (choice of breed, breeding itself)
2. Keeper (technological, nursing and veterinary care, working conditions and knowledge of employees)
3. Nutrition (quality production of top feed, compilation of rations)
4. Environment (quality requirements, ethology and welfare).
It is not possible to say that for the successful breeding we need only perfect race (genetics). It is impossible either to claim that the decisive factor is nutrition. Also the conviction that perfect stable and parlour makes the milk is mistaken. The perfect carers cannot create higher than average herd only by formidable care. The keeper has to see all of these aspects complexly and respect them.
At this point the thesis starts to focus on carers. It is obvious that quality of carers is rather neglected factor. This thesis describes analyses of carers nature and their approach towards their job in relation to behaviour dairy cows and their production pointers. In my thesis mentioned studies state that after designed and applied intervention of stereotyped behaviour of carers, that means treatment of dairy cows and approach to their work in farms - we can see increasing production of milk. The carers said that the dairy caws were calmer, it was easier to manipulate with them and that they are convinced that positive approach towards the animals has a huge positive effect.
The last part of the thesis shows how to apply found information into practice and how to proceed. Training of employees is one of the possibilities that start to be more and more important - not only abroad but in The Czech republic as well. Training is focused on
correct way of milking, taking care of cattle and hygiene in breeding, so that the health condition of dairy cows is good and the production is quality and harmless.

Comparison of Selected Parameters of Technologies Utilizing Renewable Energy Sources with Technologies Utilizing Non-renewable Energy Sources
Špot, Marek ; Havránek, Miroslav (advisor) ; Hák, Tomáš (referee)
The bachelor thesis "Comparison of selected parameters of technologies utilizing renewable energy sources with technologies utilizing non-renewable energy sources" compares from several points of view nine specific Czech power stations of various technologic types. The evaluation comes from three different graphical data representations (based on so-called three pillars of sustainability) and proceeds primarily in compliance with technologic types and secondarily by renewable/non-renewable sources distinction. However, attained results aren't considered final but are subjected to questioning and description of eventual distortions from data-graph conversion. Individual parameters are not to be considered as equal, nevertheless precise parameter value identification and thereby results improvement exceeds frame of this paper.

Analysis of the pyrolysis process of plant biomass
Jičínská, Karolína ; Ivanova, Tatiana (advisor) ; Kolaříková, Michel (referee)
Nowadays, there is an increasing consumption of fossil fuels however their combustion is associated with release of great amount of harmful substances into the atmosphere. Polluted environment and the rapid depletion of fossil fuels lead to increasing utilization of renewable energy sources. Biomass, one of these sources, can be transformed by thermochemical and biochemical processes into material/product with a higher energy value. The promising thermochemical process is pyrolysis. It is a process where the temperature heats material without access of media containing oxygen.
This Bachelor Thesis entitled "Analysis of the pyrolysis process of plant biomass" was written as a literary review based on search and analysis of information for scientific articles from the well-known databases. The present Thesis summarized basics of pyrolysis as well as analyzed and compared various pyrolysis processes. The main processes are represented by slow and fast pyrolysis and also torrefaction. These processes are reviewed and evaluated, including technologies (reactors) that are nowadays applied. By pyrolysis process various kinds of carbon-based materials can be treated, however biomass is most commonly used for these purposes. Specific examples of scientific studies of plant biomass, which tested a potential use and output products, are also presented. The output of pyrolysis process consists of three products, namely liquid, solid and gaseous substances. The most desired output of pyrolysis is a liquid product, called as biooil, which has a wide range of utilization. In the last part of the Thesis advantages and disadvantages of the pyrolysis process and its energy and economic evaluation are presented.

Interactions of Hydrogen Sulfide Releasing Enzymes in Porcine Oocytes during Meiotic Maturation
Jiříček Hasalová, Simona ; Hošková, Kristýna (advisor) ; Tomáš, Tomáš (referee)
The reproductive biotechnologies currently represent a major scientific discipline based on a sufficient quantity of wholesome oocytes matured in vitro conditions to acquire permits for their effectiveness. The meiotic maturation is a complex process where a wide range of factors is involved in the regulation. One of these factors are small gaseous molecules, so-called gasotransmitters. These gases demonstrate number of physiological functions in the organism and the latest discovered gasotransmitter is hydrogen sulfide (H2S).
The aim of this thesis was to test the hypothesis according to which there are enzymes present in porcine oocytes that produce H2S (CBS, CTH, 3-MPST), their distribution is in interaction and their joint actions influence the process of the meiotic maturation. The resulting data were obtained on the basis of immunocytochemical staining and colocalization analysis.
The results proofed the presence of H2S-releasing enzymes in porcine oocytes. It was also confirmed the function of these enzymes in relation to the regulation of the meiotic maturation when oocytes cultured with triple inhibitors of H2S-releasing enzymes matured more slowly. The results also showed medium correlation dependence of enzymes CBS, CTH and 3-MPST. The combination of CBS and 3-MPST resulted in high correlation dependence which confirmed their interaction both in immature oocytes and in vitro matured oocytes.
It is evident that so far studied effects of H2S are only a fraction of skills which this signal molecule possesses. There exists a need for future experiments to help us describe and explain the acting mechanisms of H2S.
