Natural flooding in Lužnice floodplain - an holistic approach
Pithart, David ; Montagová, Martina ; Hartvich, P. ; Černý, R. ; Prach, K.
Natural flooding was analysed in the Lužnice River floodplain in a holistic approach. Benefits of natural flooding can be summarised as folows: 1. Water retention is increased due to the soil absorption, evapotranspiration, filling of oxbows, pools and natural depressions and finally the space between the river terreces. Real flood event are analysed here in terms of water distribution among these processes. 2. Natural flooding reduces the loss of ionts from the watershed by flowing the river outflouw and loss of carbon loss by slowing the decomposition processes. 3. Flooding creates and maintains floodplain geobiodiversity by re-forming of floodplain subsystems and differentation of its impact on these subsystems. For these reasons, maintaining and enchenging of natural flooding seems to be a prerequisite of sustainable management of riverine landscape.

Šára, Ondřej ; Jiránková, Martina (advisor) ; Sejkora, Jiří (referee)
Building relations with China is a topic of broad and current interest, when it comes to establishing and deepening new economic cooperation between Sub-Saharan Africa and other regions. This thesis analyses current economic cooperation between these two regions with the prevailing emphasis on the African partner. The thesis is formally divided into five chapters. The first two chapters focus on selected theoretical and factual starting points related to the main topic of the thesis, which create a foundation stone for the other chapters. In the third chapter of the thesis, selected statistical data about current trade and investment cooperation between both partners are introduced. The main goal of the following fourth chapter is to analyze real impact of mutual cooperation on the selected country of Sub-Saharan region. The last chapter of the thesis analyses a relatively problematic and widely discussed issue: the classification and allocation of financial flows from China in the Sub-Saharan Africa.

World Trade in Crude Oil
Benešová, Nela ; Čajka, Radek (advisor) ; Bolotov, Ilya (referee)
This master´s thesis deals with trade with crude oil and its impact on the world economy. Everyone, who wants to start to trade with crude oil, should find out basic terminology and information about crude oil that is characterized in the first chapter. The hunt for oil started many years ago, therefore the history is also mentioned in this master´s thesis. The second chapter focuses on the world trade with crude oil. Territorial structure and trade flows are described in this part of the master´s thesis. Nevertheless, the crude oil also has an impact on the world economy and economies of single states. The third chapter analyses states, where the inhabitants live beyond means of people from other countries but these states are so depended on crude oil that if this trade stopped, these countries would go bankrupt. However, there are also exceptions. Even though, there are states that have huge sources of crude oil, they still have to deal with financial problems. The forth chapter characterizes the trade with crude oil of the Czech Republic because it is a net importer of crude oil and the last chapter focuses on new trends in crude oil such as shale oil and trading at a crude oil market.

Art culture as a segment of the cultural life of nations
Čermák, Martin ; Patočka, Jiří (advisor) ; Hanzlík, Jan (referee)
The principal aim of this thesis is to undertake a historical analysis of cinematography in Czech Republic and France, respectively. In more detail, this analysis will concentrate on financing that flows towards film-making in said countries, while at the same time focusing on the artistic aspect of movies that are created thanks to this financing. This paper tests two hypotheses, which will be either confirmed or rejected after the analysis. First concerns the impact of political regimes on funding available to national film-making, and what effect does this have on the quality of film. The second one assesses the film quality from the perspective of special art tendencies.

The Impact of the Crisis on Sino-US Trade
Krňoulová, Aneta ; Bolotov, Ilya (advisor) ; Čajka, Radek (referee)
This bachelor thesis focuses on the economic impacts of the global financial crisis on the cooperation between the United States and the People's Republic of China. Its aim is to show how the financial crisis which was created as a local crisis at the mortgage market in the United States, affected Sino-US economic cooperation, foreign direct investment flows, trade in goods and services. The first chapter focuses on the United States and describes the formation of the financial crisis, as well as their current position in the world economy, their foreign trade and international investment position. The second chapter is dedicated to the People's Republic of China from its foundation in 1949, through the partial liberalization, up to the current economic situation. It describes the development based on the inflow of foreign direct investment and export of goods. The third chapter describes the mutual trade cooperation between the USA and China, the commodity structure of their exports and imports, the balance of services and foreign direct investment flows. The fourth and final chapter of this thesis is devoted to an overall assessment of the economic impact of the crisis on their close cooperation, and also to prediction of the future development in the next five years.

Gas trade
Andrsová, Nicola ; Čajka, Radek (advisor) ; Bolotov, Ilya (referee)
The bachelor work deals with the natural gas as a commodity, transport and storage potions, world gas market and its development since 80s of the last century. It also extends the possibility of using gas in the future for a variety of purposes. The main theme is the Czech Republic's position in the global gas business, especially in terms of relations with the European Union, Ukraine, and Russia. The analysis in this part is based on data on gas reserves in the world, the volume of production and consumption of gas and gas flows throughout Europe from the major exporters, especially the gas flows from Russia via Ukraine. For the Czech Republic, it focuses on the possibilities of enhancing energy self-sufficiency, especially the construction of the gas tank in a premises of Rožná gas storage and Mozart pipeline, which would mean the Czech and Austrian gas system hook-up. Consideration must also be given the ongoing Russian-Ukrainian gas crisis and its impact on gas supplies to Europe and/or the Czech Republic. The aim of this work is to outline the development of gas trade, the possibility of its further use, otuline the basic principles of the European legislation and the options for enhancing energy self-sufficiency of the Czech Republic and also to evaluate the Russian-Ukrainian gas crisis.

Selection of suitable fluid flow directions in laminar flow tubular cooler
Krobot, David ; Kohoutek, Josef (referee) ; Jegla, Zdeněk (advisor)
This master’s thesis is devoted to problematic of selection of suitable flow directions in double pipe heat exchanger. First chapter is oriented to the construction of tube heat exchangers. It is also discussed impact of construction solution to the flow character and changing of his process parameters. The difference between parallel and countercurrent flow is also occurred in this parts. The next chapter is focused to the basics of heat-hydraulic calculations of heat exchanger. This also means explanation of ways of heat transfer and heat exchanger function. There are told about specific access to the solving problem of fluid laminar flow. The third chapter is detailed focused to the calculating of heat exchanger. At first is discussed factors, which have impact to the flow character. Next are detailed descriptions of design and controlling calculations, including more alternative ways to solve it. Next chapter exploit those results for deciding, which flow arrangement will be better for given case. Last chapter contain realization and reformulating of process heat exchanger calculating to the program code in Maple. There is also description of used algorithms and operating with them, so any user could be able to work with it. In this master’s thesis are used many examples from attached programs on different parts.

Free Riding as a Possible Source of Conflict in Group Work
Iten, Naomi ; Hiršová, Miloslava (advisor) ; Syrovátka, Oldřich (referee)
Theme of this bachelor's thesis is problem of free riding (freeloading on work of others) in a group work, the evolution of its effect and impact on the group and its members. I analyze the phenomenon and background in which it is happening in and its possible causes and manifestations with regard to free rider and other members of the group. Also I examine this phenomenon in background of selected students of the Faculty of Management at the University of Economics in Prague. The result is a predominantly negative attitude to free riding and even less or more radical concept of solution. Based on acquired data, opinions of students and theoretical knowledge, I offer recommendations which could help to prevent free riding or partially removed it. Obtain the data to formulate the recomandations via questionnaire and to present them I use a descriptive statistical analysis.
