Impact of low oil and natural gas prices on the economy of Qatar since 2014
Šamánek, Ondřej ; Stuchlíková, Zuzana (advisor) ; Hasík, Gabriel (referee)
The bachelor thesis examines the impact of the oil and gas prices slump, which befell the world in 2014, on the economy of Qatar. The main objective of the thesis is to evaluate if and to what extend the price collapse influenced the relevant economic indicators and behaviour of the state and companies active in the affected field. The selected objective is examined using the method of data comparison, namely before and after the price slump, and with the help of the case study, in which the qatari company operating in the oil and gas is examined. From the conducted analysis it is possible to conclude that Qatar was directly influenced by the oil and gas prices collapse: its GDP slumped, fiscal deficit increased. The analysed company also experienced troubles caused by low prices: one year after the price slump, total amount of assigned tenders to company decreased substantially and historically high number of tenders was cancelled. Conclusions deriving from the thesis might be applied to other oil and gas export economies in the Persian Gulf, for fundamental traits of such economies are shared with the economy of Qatar.

The nutritional importance of polyphenols in berries
MARTANOVÁ, Anna
People's nutrition is inseparable part of our lives. We could include substances, that we know are healtful, to our food. If we don't have enough of the substances, we can see negative effects on human organism. The substances are named micronutrients and vitamins. We could enrich a diet with substances that we think are healthy, but their deficit doesn't case pathological symptoms. Food which we put to this category is possible to name as function food. Function food contains substances which have positive effect on our health. One of the substances are polyphenols. This issue is very interesting for me, because polyphenols are compounds that are among others particulary found in berries, especially in blueberries. Blueberries are berries that are widespread throughout the world. One of the best sources of blueberries is also Sumava, where I come from and where blueberries are well connected. The first part of my thesis is about the functional foods and ingredients that make these foods Functional foods. Ordering: probiotics, prebiotics, synobiotiks, micronutrients, fytochemiks and polyphenols. Farther the first part deals with berries, specializing in blueberry and its properties and composition, which can have a positive impact on human health.In the second part there were two objectives of the work. The first aim of my study was to determine the diet, which includes foods that contain the optimum intake of polyphenols, equivalent to 120 ml of fetal native blueberries. Polyphenols are that part of blueberries, which make them so special. In the diet were preferentially embedded short dishes that have undergone heat treatment. Analyses of polyphenols in foods and beverages I got with the program GEOMED hospital Ceske Budejovice, Inc., Department of Clinical Pharmacology. Results polyphenol content were performed by HPLC. The content of polyphenols in native blueberries was laid as equal to 1 and the contents examined further product was then expressed as a multiple or ratio of the native blueberries. I take into account all these factors when drawing up the model menu. Another aim I have set is to map products in which the content of polyphenol is beneficial. There is a high number of products with blueberry flavour on the market. The content of blueberries, however, is often negligible. The surprising result was the polyphenol content in lemonade Toma, whose relative value ug / ml is 2.59 when compared with the native blueberry, which is placed as equal to 1. After the development work, in which I obtained information from the literature search, the sales network and the Department of Clinical Pharmacology, Hospital Ceske Budejovice, I would like to say that blueberries are an important source of polyphenols and that a diet which will include daily equivalent of receiving polyphenols, may not in any way differ from a regular rational diet. Not even cooking the dish precludes putting together this diet because blueberries are relatively stable against temperature changes. Inclusion of such a diet in the catering equipment could bring a positive impact in the future, especially for older people by improving memory function and balance.

Creation of the Enterprise Architecture model according to the TOGAF framework
Čapek, Jan ; Doucek, Petr (advisor) ; Zeman, Petr (referee)
The present diploma thesis aims at introducing the Enterprise Architecture and creating an abstract model of a company. The primary focus is on application and process layers as defined in the architecture framework TOGAF. The thesis is divided into theoretical and practical part. The theoretical chapter starts with a business model analysis which means to describe mission vision and companys values as a part of the strategy framework. Furthermore the business processes are described in the latter part of this section. This chapter attempts to explain how to map a business process and to categorize it by nature and maturity level. Penultimate chapter introduces the Enterprise Architecture in general. This section includes arguments as to why the companies should be concerned with the Enterprise Architecture advantages of the Enterprise Architecture implementation into the companys documentation relationship of companys core business and IT and examples of the Enterprise Architecture frameworks. The last chapter deals with the TOGAF framework where Architecture Development Method is described. This means how Enterprise Architecture model is created and how to implement changes into the layers according to the TOGAF framework. Simultaneously the last section of this chapter describes the reference models which provide graphical overview of all abstractions layers. The practical part of the thesis elaborates on the theoretical part using the Architecture Development Method process in order to create the Enterprise Architecture model according to TOGAF framework. Same as the theoretical part it only focuses on the application and process layer. Firstly the business model is decomposed into vision mission and companys values to the companys strategy and business goals in order to grasp further understanding of business processes detailed description. Subsequently the abovementioned aspects are recomposed to create process map which provides the management overview. The application layer undergoes the same process; nonetheless the process map is replaced by information system description and reference model creation. Once the models are created the thesis compares them with the business and strategic goals. The benefit brought by this thesis is critical evaluation of current status to propose changes to achieve target architacture according business and strategic goals established by management.

Homestead with accommodation
Staňová, Monika ; Papranec, Michal (referee) ; Petříček, Tomáš (advisor)
Annotation The aim of this bachelor thesis is a project of a new building of a family farmhouse with accommodation situated in the cadastral area of Lezník. The farmhouse is sitting on the suburb of the village and is surrounded by old original barns. This house is designed for a family of 5 members. A part of the farmhouse is used as a Bed and Breakfast for up to 12 people. Each part of the house (living and accommodation) has got its own entrance. The building is covered with a double pitched roof in an L shape. The roof above the living kitchen is designed as a shed (lean to) roof. For the main wall structural system we have used Porotherm system, apart from the gables which are constructed as a wooden structure due to the size and unusual shapes of windows. The facade is designed as a combination of direct external insulation and ventilated facade. Documentation has been prepared for this building construction. The graphical part of this documentation has been processed in the AUTOCAD software.

STRAIN ENGINEERING OF THE ELECTRONIC STRUCTURE OF 2D MATERIALS
del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.

The Liberation of Pilsen 1945 in Photography
Křenová, Tereza ; SILVERIO, Robert (advisor) ; JANOŠČÍK, Václav (referee)
This bachelor thesis deals with liberation of Pilsen in May 1945 by american army in photography. The aim of this thesis is finding and collecting archival materials and placing them in a historical-political context. Communist regime changed the portrayal of historical events and directly influenced the amount of exisiting photographs, documents and lives of those who created them. Important part of this bachelor thesis is working with those archival materials – particularly with photographs capturing arrival of Americans and their stay in Czechoslovakia at the end of WW2. Both professional and amateur photographers created valuable photographs as they witnessed the liberation of Pilsen. These photographs became in spite of communist propaganda a clear evidence that Pilsen was liberated by american army.

San Minn (or) An Artist who prefer creating and paintings than his life
Zeya, Pyin Nyar ; JANEČEK, Vít (advisor) ; VOJTĚCHOVSKÝ, Miloš (referee)
No one can control a painter artist’s freely thoughts and ideas and although his paintings were under the high pressure and banned by force, the artistic value of his materials never go down. So that I am writing this paper.
He, San Minn has broken out the mainstream of Burmese painting field, he never made business paintings as well. He keeps his belief on the art of paints and he is always finding for the new way to make his paintings. His materials are very different from other Burmese painter artists’ materials. His style is unique in Burmese paintings. So I can get a chance to study of his style, ideas, ways of thinking and his determination on the art works.
My paper can show a painter artist’s life who grew up under the military rule for 50 years and the situation and history of Burmese painting field. Then not only people who are studying the painting subject, but also other people can know about the subject of Burmese painting and field of artists. I dare say that my paper must be colorful and fruitful.
As a painter artist, it seems that he wants his audience to feel his materials but he rare to show his real life behind the pictures. For me, I can get a chance to know about his real life for my thesis paper.
xxxxxxxxxx
Thesis Statement
My thesis can be useful for everybody who is interested in Burmese contemporary art field.
This is the biggest chance to read about one of the most famous, important and significant artists and art movements of Burma. His paintings are reflecting his journey through over 40 years of censorship, but he was not afraid to tackle political and social issues.
Many of San Minn's art works are based on autobiographical, making sharp social commentary on the popular culture, social values and scenario circumstances where he has lived in.

Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.

Plasma spraying from liquids: plasma liquid interaction and coating build up
Tesař, Tomáš ; Mušálek, Radek ; Medřický, Jan ; Lukáč, František
Plasma spraying from liquid feedstocks is a rapidly developing field of thermal spraying since the coatings prepared from liquids exhibit some unique features, such as high hardness, thermal shock resistance or low thermal and electric conductivity. The key factor influencing the final coating character and properties is the input material which may be in the form of a suspension or a solution. Parameters of the selected suspension (solids concentration, viscosity, surface tension, chemical composition, etc.) or solution (concentration, etc.) determine its interaction with the plasma jet which strongly influences the coating buildup. This proceeding introduces the problematics of the interaction between the liquid feedstock material with the plasma jet and presents the way of evaluation of the coating buildup.
