This thesis deals with the radial forces acting on the impeller of a centrifugal pump. It focuses on the centrifugal pump type BETA 26. It addresses forces acting on the pump shaft. These forces are converted into the impeller. The most extensive part of this thesis is devoted to the experimental measurement and evaluation. The results are summarized and processed graphically.

This thesis deals with the surface of a gecko in relation to its adhesion ability. Understanding the mechanism of movement and adhesion principle is important for the design and manufacture of nanostructured material. Likewise, knowledge of the origin of the self-cleaning ability allows the description of the influence of surface structure on movement and forces acting at the contact. The work describes the process of making nanostructured surface, which was modified in order to obtain maximum adhesion forces. The material properties were determined by the values of wettability and by force spectrum measurement. Their results were compared with the theoretical assumption of capillary forces and other possibilities to increase adhesion.

The concern of this thesis is the intervention to protect nationals from the perspective of international law, which is part of a broader issue of the use of force in international relations. Although this type of intervention was already a part of the international community before the Napoleonic era - even in the 20th century it was not a minor feature - it is still controversial, and subject to many different interpretations. There are not only big differences between the opinions of particular states of the international system, but also among the international law scholars. The main goal of this Master's thesis is to answer the research question: Is the intervention to protect nationals legal according to the rules of international public law? Besides the Introduction and Conclusion this thesis is divided into four chapters. The first is devoted to the definition of the given phenomenon. It is an integral part of my thesis, because there is no legal definition of the term intervention to protect nationals or of the term intervention. The second chapter deals with the rules of use of force within international relations - above all with Article 2(4) of the UN Charter (which prohibits the use of force) and its exceptions. The interpretative controversies are also included in this chapter. The...

The diploma thesis aims to verify the validity of neorealism, institutional neoliberalism, and critical geopolitics about consequences of the economic globalization for the structure of Finnish and Swedish defence forces. For this purporse, the author primary used the method of congruence. The next step led to the comparison of congruence between observance implications and theories predictions. Based on the results of the Finnish defence forces, the theory of neorealism was confirmed because there is no significant shift in the scope/structure of defence forces in the favor of expeditionary/reconnaissance units. Moreover, there is no evidence to waive the balance of power reasoning even in the geopolitically-low-intesive region. Last but not least, it was shown that difference between the Finnish and Swedish geografic location is one of the key factor for its distinct approach towards potentional threats and instruments how to resolve them. Key words: economic globalization, security, defence forces, Finland, Sweden

The main subject of this project is the international migration of the labour force. There are two questions which it responds to. The first one: Is it necessary for the Czech labour market to use the foreigners (immigrants) labour force? The second one: Is there a risk of abnormal work emigration and shortage of the Czech national labour force as a result of it? The first part of this project describes current situation at the Czech labour market, potential impacts of the shortage of the labour force and the main factors that are able to improve the situation at the labour market. There are particular analysis in the second part of this project. The object of them are the migration differences among EU countries as same as the imigration and emigration flows of the labour force. One marginalized but very important migration factor is mentioned in the part 8. This is related to differences in child benefits in EU countries. In the part 9 I realized my own empirical survey. It is concentrated on the work migration and migration motives in three various regions in the Czech republic. The result of this dissertation is: 1) The work imigration to the Czech republic is necessary and adequate. 2) The work emigration of the Czech labour force is marginal and not dangerous for the Czech firms and Czech labour market.

The aim of this thesis is to evaluate the lawfulness of the use of force by the United States of America against the so-called Islamic State in the territory of Syria, in terms of Ius ad bellum. For this purpose, the thesis is divided into three parts. The first part focuses on assessing the subjectivity of the Islamic State. In particular, the subjectivity is examined with regard to the criteria arising from the Montevideo Convention on the Rights and Duties of States and from professional experience. The Islamic State is assessed in terms of defined territory, permanent population, effective government, capacity to enter into relations with other states, independence and legitimacy. The second part deals with the legal regulation of the use of force in international relations. After the presentation of the historical development, the attention is paid especially to the UN Charter and the ensuing prohibition of the threat or use of force in international relations. In the context of the use of force against the Islamic State, legal exceptions to this prohibition, which could be used in the fight against the Islamic State, are presented. First, attention is paid to the exceptions resulting from the UN Charter, which are self-defense under Article 51 and actions under Chapter VII. Two types of...

Diploma thesis is dealing with proposal of suitable farm implements and technologies for tractors of over 250 kW according to chosen methodologies at agricultural business AGRO Slatiny a.s. The introduction specifies a brief characteristic of selected agricultural business which is followed by a description of soil processing methods and comparison of wheeled and crawler tractors. In the next section there is a characteristic of 3 powerful tractors of over 250 kW and implements which are used by those tractors for soil preparation. Furthermore there is a specification of main objective and applied methods. The main goal was calculation of original implement's parameters in regards to work efficiency and economic evaluation. In case of unsatisfactory results the objective is to propose new implements in order to work more efficiently and have better economic results.

The theoretical part of the diploma thesis deals with soil qualities which influence the soil processing. The soil processing itself is described in the theoretical part as well as advantages and disadvantages of the specific processing, a choice of technology for effective soil processing and economic aspects of the processing. In this part there is an extract describing a test of a tractor pulling and reasons for making the test of pulling in laboratory and field conditions. The practical part of the thesis deals compares two methods of a tractor pulling power during field tests. A belt tractor John Deere 8320 RT and a wheel tractor New Holland T7050 were tested. The target of a pulling test in ter-rain was to define which resistance makes a soil in specific conditions and which pulling power is needed for a certain working output on a given land. The results were pro-cessed and evaluated with computer technology. The whole measurement took place with support of a BEDNAR FMT company.
