Comparison of production and conditions of use of liquid biofuels in different countries
Semerák, Adam ; Pecen, Josef (advisor) ; Krepl, Vladimír (referee)
Biofuels production has experienced rapid growth in recent years. Many countries initiated legislative measures to promote their development, production and use in the transport sector. However, there are also growing concerns about the economic, environmental and social sustainability of biofuels, as well as their ability to truly meet the expectations of energy security.
This paper attempted to point out the complexity and diversity of the production and use of liquid biofuels in the transport sector while using available information resources. More specifically, bioethanol and biodiesel which are most commonly used biofuels. Furthermore, he also tried to point out the diversity of characteristics and impacts in production and use of liquid biofuels, as well as the importance of consideration of the specific local conditions. That was examined from four perspectives of sustainability: technological, economical, socioinstitutional, and environmental. To illustrate the diversity and interdependence of the impacts of this whole issue two countries with very different human development indexes were selected. The Malaysia and India.
At the basis of this paper the author concluded that for successful and sustainable production of liquid biofuels there must be taken into account all the factors examined equally. He also emphasized the importance of further research of this renewable energy source in terms of ensuring future energy security.

Analysis of Basic Mechanization Means for East African Countries
Špaček, Marcel ; Krepl, Vladimír (advisor)
The goal of this thesis is to create a survey of the most widely used means of mechanization for plant and livestock production with use of the available sources in the East Africa countries. It would be a survey of agricultural machinery and implements used for tillage, sowing and planting, plant protection, harvesting machines and post harvest technology. There would be a necessary mechanization and technology for livestock production. The basic division of this study would be on hand tools, animal drawn implements and tractor implements. Part of analysis would be a review of equipment and tools development from the past to the present.

Torrefaction of biomass for energy use
Sverkunová, Kristina ; Ivanova, Tatiana (advisor) ; Krepl, Vladimír (referee)
The Bachelor thesis is focused on torefaction of biomass for an energy use. It describes the technology including basic reactors, compares wet and dry torefaction and used materials that can be used for an agricultural waste. In the thesis I compared advantages and disadvantages of torefaction considering all hydrophobic, grindability and emission of greenhouse gasses.
Second and the important part of the thesis is the recent commercial use of biomass. Data are mainly taken from the SECTOR study, which was made in March 2016. So it can be considered as a recent data. This part is also concentrated on possibilities of faster development of this technology thanks to the commercial use. It is also explaining the importance of norms, which have not been regulated yet.
The conclusion refers to the main assets of this technology, when the usage of fossil fuels and its more ecological substitutes are discussed. I mentioned the problem of a carbon footprint is connected to a possible raise of wood materials import, that will be unavoidable in order to satisfy expected demand for year 2020.

Czech-Iraqi relationship and nowdays Iraq
Khalid, Ahmed Mohamed ; Jeníček, Vladimír (advisor) ; Voráček, Emil (referee) ; Gombár, Eduard (referee) ; Krepl, Vladimír (referee)
This work cover the topic of bilateral cooperation between two countries with different political-economic and cultural-historical characteristics, that is the Republic of Iraq as developing country and the Czech republic on the other side ,which is classified by the OECD as advanced ,industrialized country. It focuses on the often debated issue, namely how to consolidate and streamline both an economic and political cooperation of the Czech Republic with the newly formed society in the Republic of Iraq. Despite a long tradition of joint relations, nowadays the Czech Republic is not a major player in the development of Iraq, but it has its potential to thrive in partial aspects of the transformation of Iraqi society such as agriculture and the environment, energy, transport, but also active in the field of counseling institutional transformation of the country such as government and regional institutions, human rights, etc. serves as a type of connecting link in this effort. This can be presented as an international development cooperation, which may very well continue to the long tradition of Czech-,resp. Czechoslovakian -- Iraqi relations. The scope of development assistance is both Czech and world-level expectations, particularly in terms of volume, but you can talk about it as a precursor of a deeper economic cooperation The total amount of development funds arising from the Czech Republic in Iraq represents a considerable amount, for example, between 2003 and 2005 it was 78 million USD. In the same period, the trade exchange was only 17 million USD. It should be noted that much of the development funds can be described as a humanitarian (building hospitals). In addition, it must be pointed out that the solving of development and humanitarian projects in Iraq is very problematic. It is necessary to use local co-workers, who often choose between work and cooperation with international organizations for which they can get a wage, thereby they face the pressure from the local environs that suspect them of cooperating with those who destroyed the country and who occupy it. These attitudes of local people slow down many development objectives and overall reduce the sustainability of development activities. That is why international organizations are focusing on the supply of capital equipment, in which they may engage private capital and thus open the way to Iraq to companies, which would be financially beneficial to both parties, i.e. the Iraqi citizens. To penetrate the Iraqi market with a new product or service, however, means not only to face competition from local products, but also the recently mentioned increasing activity of the neighboring Islamic countries, especially Turkey and Iran, but other producers of cheap goods from South and Southeast Asia. In this respect there is rather a chance for the Czech Republic to approach wealthier clientele, which will be (with economic growth and wealth of the Iraqi people) looking for higher quality goods for which it would be willing to pay.
