Hajiyev, Shahmar ; Horák, Slavomír (advisor) ; Žídková, Markéta (referee)
This thesis will focus on Azerbaijan's oil and gas industry; how the country uses its energy revenues within its economy; how it avoids economic pathologies such as the "Dutch Disease"; Azerbaijan's role within the Caspian Basin, and finally, the European Union's energy security and how Azerbaijan's energy resources can impact it. The Republic of Azerbaijan is a natural resource-rich country, and uses its energy resources as a means of socio-economic advancement and stability. Recent developments within the country's natural gas sector have allowed Azerbaijan to become a net gas exporter. The EU's growing demand for energy resources illustrates how important it is for states to have access to secure, stable, and diverse sources of energy. Energy resource exploration and the subsequent export of these products to international markets play a crucial role for the Republic of Azerbaijan's economy. Therefore, this thesis will first provide a brief evaluation of the history of Azerbaijan's energy sector; an overview of the current situation and recent developments; and explore how energy revenues are being distributed in the economy. It will define the interests of other important actors such as Russia, Turkey and the USA; and finally, it will assess the EU energy security, the role of Azerbaijan as the...

Geopolitical aspects of Russian energy policy toward the European Union
Seidlová, Alexandra ; Jelen, Libor (advisor) ; Vogt, David (referee)
The capacity of natural gas which is imported from Russia has a major part in the European energy mix. The over-dependency on Russian supplies invokes fears from potential dangerous geopolitical influence of Russia on states of the European Union (EU). The objective of this work is, by the method of critical recherché, to analyze principal geopolitical aspects than geoeconomical aspects of the Russian energy policy in stance to the EU and even to states in the region of Caspian Sea on the examples of the chosen European and Russian pipeline projects. The attention is also devoted on outer actors in the form of energetic companies, which enter in to Russian-European energy chess field. In the end of this work the possible diversification bases and the guess of the future development of energy policy is being discussed.

Czech Republic and its connection to new LNG terminals - strengthening of the gas security
Prouza, Petr ; Kučerová, Irah (advisor) ; Binhack, Petr (referee)
Master thesis "Czech Republic and its connection to new LNG terminals - strengthening of the gas security" examines the level of gas security in the Czech Republic. Dependency of the Czech Republic on gas supplies from foreign countries is almost 100 %. Russian federation is dominant supplier with roughly 75 % of the supplies. High dependency on one exporter is considered hazardous from energy security perspective. The Czech government should strive to change and improve this situation. The diversification is considered as a useful tool to improve the gas security. Currently there are new gas projects built in neighboring countries, which may influence energy security of the Czech Republic. The study researches the impact of these new projects on the Czech Republic. Namely we focused on gas pipeline Nord Stream and its Czech connection Gazelle, which will connect North Germany and Bavaria through the Czech Republic. Second project is gas network called "the North - South Corridor" connecting Baltic and Adriatic Sea. The North - South corridor may be potentially linked up to the new LNG terminals Świnoujście in Poland or Adria in Croatia. Furthermore, there are long-lasting plans to open new "South" gas route from Caspian region to Europe. The main goal of this thesis is to explore real...

How to prevent the proliferation of Legionella pneumophylis in hot water in the hospital Czech Krumlov
TUREK, Jan
This diploma thesis deals with microbiological quality of hot water in a hospital in Cesky Krumlov as well as hot water piping condition with respect to Legionella. It also deals with arrangements for improving the quality of hot water in this hospital. The subject and target of this thesis are the findings of the mentioned parameters based on own observations, technical documentation and analysis of warm water performed by an accredited laboratory. The hospital in Cesky Krumlov, the construction of which began in 1909, was built in 1911 as the 'Nemocnice Císaře Františka Josefa I.' As the time went by, new buildings were built up. The hospital was renamed to 'Všeobecná veřejná nemocnice' in 1942. In the following years the hospital expanded until the current condition. Water quality and presence of Legionella is a world-wide issue, which we must fight against. The thesis is divided into two parts. First, theoretical part, which includes both general and specific knowledge about Legionella, its health risks, the environment in which it occurs, possibilities of eliminating, suitability of the material for hot water pipes, gained in professional literature and a part of the Czech legislation dealing with public health protection, the law 'No. 258/2004 Coll.' in actual version and quality of drinking water and hot water. In the second, empirical part, I focus on the situation of the hospital in Cesky Krumlov from 2009 till 2015, concerning newly built boiler room and the whole distribution system of hot water regarding Legionella. Particularly I focused on materials used for ecologisation of the gas boiler room and materials used for hot water pipes and actual state of water distribution in individual buildings of this health care facility. I mentioned the analysis of the water samples performed by an accredited laboratory with corresponding technical documentation, which concerns the water distribution system, provided by the medical facility. I used secondary data analysis to evaluate these documents. Regarding the results from 2009 to 2015 the microbiological quality of warm water doesn't meet the limits defined in the Attachment No. 3 of the above mentioned law Order 252/2004 Coll. Limit value for colony forming units of Legionella is set to maximum of 100 CFU. In most of the samples this limit was exceeded by series of units up to hundred thousands of units. The last results in 2015 prove improvement of the unfavorable situation. In that year the analysis was tested three times. First in February, where the CFU units were 'only' in hundreds, with the top value of 550 CFU in the Postacute Care ward. Second analysis was performed in June that same year. Results were acceptable. The highest value was 64 CFU. Last analysis in the hospital was performed in December. Increased concentration of Legionella was again in the Surgery building. There were established of 1400 colony forming units. There were 300 CFU in the Postacute Care ward and the limit value of 100 CFU was in the ward of Internal medicine. The answers to research questions 'How to prevent reproduction of Legionella peumophylis in the water distribution system of the hospital in Cesky Krumlov?' and 'How to ensure a sufficient amount of quality hot water in the medical facility?' are included at the end of the stated recommendations. A risk factor causing the fast reproduction of Legionella is the old water distribution system in most of the buildings and low water temperature of water leaving the boiler, which is 55°C. All mentioned results and evaluations are included in this thesis as well as attached pictures, which show the environment and situation within the Health Care Institutions.
