Stanovení antioxidačního statusu u potkanů při zkrmování pšenice Citrus
Bendová, Kateřina
This thesis examines the influence of wheat Citrus with higher content of lutein in comparison with common wheat on antioxidant activity of the rat blood plasma and liver tissue. In the experiment, 32 male rats of Wistar strain were used. The influence of the feeding of yellow wheat varieties Citrus on antioxidant activity was measured in the blood and liver tissue. The experimental group (N = 16) was fed with dried granules of 100% wheat meal from Citrus. The control group (N = 16) was fed with similar feed prepared from two common wheat. Content of crude protein was the same in the both group. Body weight gain were followed in three-day intervals and feed consumption was followed daily. Antioxidant activity was measured by DPPH, FR, FRAP and ABTS methods. Values are expressed in gallic acid equivalent. In the blood significant differences (P < 0.05) of antioxidant activity was determined only by ABTS method between "Citrus" group (405.51 +- 7.64 mg /ml) in comparison to "Control" group (479.99 +- 22.54 mg/ml) in contrary to expectation this value of control group was of 18% higher. Values of other antioxidant methods were not significant. In the liver tissue only average value of ABTS method was little higher in Citrus group (409,439 +-13,626) in comparison with control group (389,493 +- 9,271 mg/ml). Similar situation was with DPPH method (20.711 +- 0.867 in Citrus group and 20.037 +- 1.109 mg/ml in the Control group) and difference was also not significant (P> 0.05).

The progress of wheat prices in France and in Germany between 1531 and 1785
Střeštík, Jaroslav ; Mikulecký, M. ; Mikulecký, L.
Mean annual wheat prices in Paris and in Cologne during the 16th – 18th century display a considerable similarity, which may be expected due to the small geographical distance. In the long-term scale the prices increase, later the increase becomes slower, and this course is similar in both countries. This variation is supplemented by short-time fluctuations, again similar in both countries. In the spectra of these time series a significant peak appears in the periods near 130 and 60 years, further ones near 35 and between 14-15 years, the latter being more apparent in data from Paris. The period of solar cycle (11 years) is not significant here. Correlation with mean annual air temperatures and mean annual sunspot numbers is negative, but only a little above the limit of significance (it moves between 0.14 and 0.22). In the long-term change long-term variations of mean annual air temperatures and solar activity, valid for both countries, reflect themselves. After subtraction of the parabolic trend these correlations become lower, on the other hand, correlations with precipitation totals are more distinct. All correlations are a little higher in Germany than in France.

The Exploitation of Functional Capacity of Robotic Milking Machines in System of Free Moving Animals.
REICHOVÁ, Sandra
The aim of the thesis was to assess objectively the exploitation of the functional capacity of milking machines in the system of free moving animals. There were data coming from seven agricultural companies analysed in the thesis. The data collection took place from January to November 2009. We were provided with the preliminary data by the individual farms taking part in a programme called T4C. The information on problematic dairy cows comes directly from their breeders. The average production of the dairy cows was the first assessed criterion. The highest production (28.79kg) was achieved by little private agricultural companies. The lowest production (25.22kg) was ascertained in middle-sized companies. As far as the breed of dairy cows is concerned, the Holstein dairy cows gave the highest possible amount of milk (40.43; 30.16 a 27.01 kg). The CRV Fleckvieh cattle dairy cows gave the lowest possible amount of milk (24.83; 21.04 a 22.74 kg). The assessment of the number of milking by means of the robotic milking system represents the next criterion. Little private agricultural companies showed the highest frequency of milking (140.88). Whereas the big agricultural companies showed the lowest frequency of milking (119.28). Mostly the Holstein dairy cows were milked by the robotic milking machines (130.34). On the other hand, the CRV Fleckvieh cattle dairy cows were milked least by the robotic milking machines by contrast (107.94). The middle-sized agricultural companies achieved the highest number of milking per dairy cow, per day (2.47). The little private agricultural companies proved the lowest number of milking per dairy cow (2.34). The mixed herds of the Holsteins and CRV Fleckviehs proved the rate of 2.47. The Holstein dairy cows showed the milking frequency 2.45 per day while the CRV Fleckvieh dairy cows 2.32. The dairy cows from the big agricultural companies went to be milked by the robotic milking machine most frequently from the point of view of willingness, what follows is that these dairy cows showed the highest number of refusals per one milking (2.19). The lowest values of this criterion were shown in little private agricultural companies (1.10). With reference to the breed, the values of this indicator proved the lowest number of refusals (1.85) whereas the CRV Fleckviehs showed the highest number of refusals (2.25). The exploitation of the time capacity has been proven as the most effective one - 78.61% in little private agricultural companies. Whereas the lowest time exploitation has been proven in big agricultural companies - 68.11%. As far as the cow breed is concerned, it was ascertained that the Holstein dairy cows were milked longest -73.21%. On the other hand the CRV Fleckviehs were milked shortest - 63.17%. The highest amount of the dairy cows that needed to by accompanied to the robotic milking machine was recorded in big agricultural companies - 20.1%. Remarkably lower number of problematic cows was ascertained in middle-sized agricultural companies - 9.7%. The number of problematic cows in little private agricultural companies proved to be similar to the number in middle-sized agricultural companies 9.3%. It was ascertained that the most problematic dairy cows came from the mixed herds - 18.7%. The CRV Fleckviehs were the least problematic - 8.8%.

Biology and control of catchweed
VONDRUŠKA, Jakub
A very limited range of crops provides the human nutrition. In some time there was selected a little amount of weedy species that plays an important role with respect to quantum and danger. Galium aparine belongs to these species. Therefore an herbicide experiment was carried out with Triticum aestivum catering for a chemical regulation of this weed. In particular 26 varieties of a half of a hectare there was used 21 herbicide preparations and their combinations altogether in demanding conditions of low preparation of soil. It was realised at a land with a large amount of Galium aparine. Most of the preparations had a very good effect regarding the actual control. At some of them Galium aparine nevertheless outgrew and produced seeds. Although these seeds were produced in a little amount, they supply the reserve in a soil. In the literary recherche are described biology, harmfulness and potential methods of regulation of Galium aparine.

Ambulatory social services for citizens with disabilities in the region of multicipaity with extended field of aktivity Trhové Sviny
KABELÁČOVÁ, Marie
The work engages in public awareness of ambulatory social services in the region of municipality with extended field of activity Trhové Sviny. The theoretical part characterises people with health handicaps, their families and integration of such people into society. Furthermore it describes workers and providers of social services and the situation of ambulatory social services in the region of municipality with extended field of activity Trhové Sviny. The investigative part of the work contains analysis and results of an opinion poll and analysis of people's awareness of ambulatory social services and complementary services for disabled people in the region of municipality with extended field of activity Trhové Sviny. People here are relatively insufficiently informed and also in many places of this region there is little or no accessibility of these services. As a result there is rather little use of ambulatory social services by disabled people who are citizens of this municipality.

Intergenerational opinions on dementia problematics
ŠVAŘÍČKOVÁ, Lenka
In my thesis I have focused on the issues of dementias, in particular on views and knowledge in different age groups. Dementias belong among frequent diseaes in the old age; however in my opinion this issue is very little discussed. In my thesis I have attempted to determine the knowledge and experience in three age groups (the youth until the age of 25, middle age until the age of 45 and pre-senior age, that is persons older than 50 years of age). It has been of particular concern to me if knowledge and awareness if the issue are linked to increasing age. The thesis consists of a theoretical and a practical part. In the theoretical part, I focus on the issues of dementias, from a social point of view in particular: from health field I have attempted to choose the most important information, which is necessary to understand the issue and which should also be mastered by those who care for persons suffering from the disease. In the practical part, I have included transcripts of interview with respondents who answered my questions in connection with the disease. I have chosen a qualitative surfy, method of inquiry and semi-structured interview techniques to obtain the data. Three respondents agreed that I record the interviews and transcribe them in a verbatim manner. These interviews have been transcribed word-for-word including colloquial expressions that respondents used. Other respondents did not agree to record the interviews; their answers have been noted in writing only. From the acquired interviews I have found out that most of the respondents have essential knowledge however they often do not know particular answers or are uncertain of them. I have chosen a male and a female from each generation to represent views of both sexes. I have determined that the knowledge is not linked to age: all respondents displayed basic information about the disease; however it was those respondents knowing or caring for a person with dementia who were able to explain the information better. On the basis of the information I have obtained from the interviews I consider it to be a good idea not only for physicians, organizations (especial nursing homes) but also mass-media to arrange for spreading the important information among all generations.

The representation of gender of ICT professionals mediated by Czech daily MF Dnes and monthly magazine Elle in 1996 and 2002
Vostal, Bohumil ; Jirák, Jan (advisor) ; Wolák, Radim (referee)
This thesis uses feminist theories and concepts of representation and stereotypes to examine the representation of gender of ICT professionals in two periodicals - a medium-sizes "Serious" newspaper Mladá fronta Dnes and a women's life-style magazine Elle. The main purpose of the thesis was to perform the first analysis of representation of ICT professionals in media in the Czech Republic. The gender issue in this field of media representation has never been explored before in the Czech Republic. The thesis incorporates results from the years 1996 (before the massive proliferation of the Internet in the Czech Republic) and 2002 (when the massive use of Internet has really taken off). It examines news and feature magazine texts, illustrations, photos and cartoons. Content-analysis results revealed a much greater proportion of males than females in both content and illustrations. The hypothesis that "field of ICT will be represented as a masculine domain - this the masculinities will prevail in field of ICT" was confirmed. At the same time, the research indicated that an analysis of a more diversified sample of earlier Czech and Czechoslovak media sources is necessary in order to provide a more complex view of representation of male and femal professionals in the ICT field. Further research could focus on the...

The War in North Africa - historiographical presentation
Drda, Václav ; Nigrin, Tomáš (advisor) ; Čížek, Martin (referee)
Topic of the thesis is war in North Africa. The goal is to show a quality of Czech literature (books, magazines) focused on the situation in North Africa during the Second World War. Firstly, I present the methods of my research and show a content of the thesis. Secondly, there is a historical introduction about wars in North Africa, to give some general information to the reader. The main part, as already mentioned, is about comparing the Czech writings. General possibilities of sorting the war history according to its focus have been presented. The first part, orientated to the magazines, is divided in relation with the traditional system of military history - articles are compared in its folder. The second part - comparison of publications is organized due to a time line because all the books are examples of modern military history. The beginning of the time line is the spring Rommel's offensive in 1942. The end is demonstrated by the battle at El Alamein and a withdrawal of the Africa Corps. The conclusion contains all the knowledge about the comparisons which has been achieved during this research.

The problem of waste recycling in different age groups of residents
VACKOVÁ, Jana
The aim of this bachelor thesis is to clear up the problems of separating the waste and to point out the awareness and willingness of the people to separate the waste, namely according to their individual age. The literary rewiev is concentrated on the treatment of the waste and its individual technologies. In more detail I describe individual types of separated waste and its recycling. I also follow up the influence of different characteristic of the population (gender, age, residence) in relation to their willingness to sort the waste. The thing is, that the human behavior it?s the main cause damaging our negative influence of the human society on the environment. In the practical part, I pursued the quantitative research by the method of questionnaire inquiry. Using the answers in the questionnaire, I found out which factors influence the separation of the waste with the population. The basic factors were the age and the gender. The aim of the bachelor thesis was to discover, whether the individual age categories differ in the separation of the waste. The most, the waste was always separated by inhabitants at the age between 36 ? 50 years. At least, at the age of 66 and plus: generally, younger people separated the waste more than older people, which may be caused by public education and good awareness of young people. On the contrary, old people were most often prevented from sorting out the waste by the illness, the distance of the containers or their unwillingness to separate was based on little knowledge and information.
