Povrchová aktivita osmi běžných druhů chvostoskoků ve smrkových lesích a na pasekách po kůrovcové kalamitě v Národním parku Šumava, Česká republika
Brůhová, Jindřiška ; Rusek, Josef
Surface activity of eight common epigeic species of Collembola were studied in spruce forests, dead spruce forests and clearings in the Šumava National Park, South Bohemia, Czech Republic: .i.Lepidocyrtus lignorum, Leidocyrus cyaneus, Pogonognathellus longicornis, Tomocerus minutus, Tetracanthella stachi, Allacma fusca, Entomobrya nivalis, Dicyrtomina minuta./i.. Five pitfall traps were exposed at each of the 9 sites in the summer and autumn periods to study the impact of spruce forest die-off after bark beetle attack (dead forests) and on clearings. Material comprising 79435 specimens was evaluated in this study using the non-parametric Kruskal-Wallis test for comparing Collembola activity between the sites and seasons. Complete linkage (Euclidean distances) cluster analysis was used for comparing the collembolan activity in all nine sites.

Chren, Tibor ; Hlinka, Jiří (referee) ; Píštěk, Antonín (advisor)
This diploma thesis deals with design of retractable landing gear for Rapid 600 aircraft. The main purpose of this thesis is to analyze different retraction options for front and main landing gear and resulting selection of suitable variants. The thesis is consequently concerned with design of selected options including proposal of automatic landing gear control system and specifying the features and characteristics of this system. In the thesis there is also included the analysis of critical flight conditions which could be detected by this system.

The Horn of Africa food crisis
Viazanková, Zuzana ; Kuna, Zbyněk (advisor) ; Petr, Petr (referee)
This work focuses on the Horn of Africa food crisis. The food problem is one of the largest and oldest problems of mankind. This problem is closely related to the problem of hunger and poverty. Lack of access to food, raw materials and water is reflected in higher tension and violence, which then results in various conflicts. The work provides a theoretical basis for this problem. The following section describes the causes of the food problem, such as population growth, lack of education, land degradation, climate change, natural disasters and the like. The practical part is focused on the analysis of statistical data on demographics, economics, poverty, foreign aid, foreign trade and agriculture of the Horn of Africa. In the last part of the thesis, there are outlined possible solutions of undesirable situation in which the Somali peninsula is located, among them an increase in the population's education, stabilization of population, the development of agriculture, change of ownership of the soil, economic growth, integration groupings and food programs.

Behavior analysis of unskilled negotiators during negotiation
Szabó, Tomáš ; Jarošová, Eva (advisor) ; Jusko, Roman (referee)
This thesis attempts to map out the negotiation strategies used by unskilled negotiators and among these, to identify those strategies which prevent such negotiators from achieving the most effective outcome. In highlighting such incorrect negotiating strategies, the thesis aims to steer academics away from using such strategies as part of their future teaching material on negotiation strategies. The theoretical aspect of this work describes the theory behind negotiating strategies and maps the features, styles and negotiation procedures which are used during negotiation. The practical part of the thesis interprets results gained from the research which was carried out. This research, which was conducted in the winter semester of the 2013/2014 academic year, involved the staging of bargaining games that were held over five separate sessions as part of the subject "Introductory training of social and management skills".

Utilize of instrumentality PSE (Pressurized Solvent Extraction) in food analysis
Grulichová, Hana ; Vítová, Eva (referee) ; Vespalcová, Milena (advisor)
This bachelor thesis is engaged in the modern method of extraction PSE (pressurized solvent extraction). There have been two types of this apparatus, One PSE and Fast PSE. In this thesis, the apparatus and its behavior is described. Extraction of anthraquinones, strychnine, berberine, glycyrrhizin, ligustilides from medical plants is presented below. These substancies are used mainly in treatment for various diseases. In this work is noticed trace elements, tocopherols, alkylbenzene sulphonate, isoflavone, dionine, betacarotene, vitamin E, polyphenol extracted from biological samples. Utilization of the substancies from biological samples is very different. Some one decreased risk of osteoporosis, cardiovascular disease, cancer and other is by contrast deleterious toxin. High attention is devoted to substancies presented in food such as polychlorinated biphenyls, various pesticides, lipids, oxysterols. These substancies are in food rather undesirable than is why their amount is determinated to the food isn´t deleterious.

Criminal activity releated to the use of illegal drugs
NOVÁK, Martin
In my thesis I deal with illegal drug use leading to criminality. Drug abuse has been a debated issue recently because drugs are omnipresent in our society. Illegal drug use has been a serious problem worldwide. Due to its geographical location, shortly after 1989 and after the fall of the Iron Curtain the Czech Republic has become both a transit and a destination country for all sorts of drugs within a short time. The objective of my thesis is to examine, describe and analyse the overall criminality in the Prague area in 2005 {--} 2007. The other concern of my research was to determine the drug addicts´ contribution in proportion to the overall criminality. I set three hypotheses: H I : The most common drug addicts´criminal activity is theft. H II : Most drug addicted criminal offenders are male. H III : The most common drug being abused is pervitin. The thesis is divided into two parts {--} theoretical and practical. In the theoretical part the development of the drug scene in the Czech Republic and crimes committed by drug addicts are described. I also give information on detection, investigation and criminal sanctions in criminality caused by drug addicts. I gathered the data from specialist literature. In the practical part I used the technique of the secondary statistical data analysis. I analysed the statistical data from 2005 {--} 2007 obtained from the Police of the Czech Republic Headquarters. The research was conducted by the quantitative questionnaire method and the data obtained were analysed. The data were put into charts and diagrams. All the hypotheses suggested were confirmed. The objective of my thesis was accomplished.

Men's antifeminist identity - critical analysis of men's critique of feminist men.
Pavlas, Tomáš ; Havelková, Hana (advisor) ; Matonoha, Jan (referee)
The general question of this diploma thesis is the compatibility of present ideas of masculinity with democracy. The thesis narrows down the field of study onto men's antifeminist identity and maps out the variety within men's antifeminist movement. The methodology of the presented research is based on semantic and discursive analyses. The identity of antifeminist men is not studied independently, but by the means of a critical analysis of the antifeminist men's construction of their relationship to feminist men. The analyzed material consists of texts in which men are critical of feminist men. The thesis shows in what ways antifeminist men use diverse discursive techniques to construct various images of feminist men, images of themselves, and images of their mutual relationships. Great attention is also paid to a critical analysis of such constructions delivered from the perspective of gender studies and men's studies; the position of the author of this thesis is also explicitly acknowledged as a departure point for a critical reflection of the discussed images, their relationships and mechanisms of their construction. Further, a collection of social practices by means of which antifeminist men contribute to the construction of "reality" are introduced. The studied case of antifeminist identity is put...
