Transport of Dangerous Substances in the Czech Republic
VANDAS, David
The topic of the diploma written assignment is "Transport of Dangerous Substances in the Czech Republic" and it was chosen for elaboration of the wholesome view on the road, train, ship and plane transportation of the hazardous materials and mixtures. These transportations represent a possible risk of damage to life, health, property or environment for the society. Hazardous materials and mixtures nowadays are being transported in large measures and there is an assumption in the future that the volume of the transported hazardous materials and mixtures will increase. For elaboration of this written assignment three hypothesis were given: a) Legal regulations of the European Union and the Czech Republic solve the problematic of the transportation of hazardous materials and mixtures well enough. b) The public has enough information about the transportation of the hazardous chemical substances or mixtures. c) People that work in the field of the transportation of hazardous materials or mixtures are well informed about the transportation of hazardous chemical substances or mixtures. For determining whether the legal regulations solve the problematic of the transportation of hazardous materials and mixtures well enough the literary sources which deal with this issue, legal regulations of the Czech Republic and the European Union and other international agreements were used. After working through these sources it was found out that the international, the EU and Czech legal regulations or agreements solve this issue well enough and emphasis is given on convergence of legal regulations of all transportations. Implementation of international agreements and legal regulations of the European Union into the legal regulations of the Czech Republic happens in the present time very fast and without failures. For figuring out the awareness of the public and awareness of the people working in the field of the transportation of hazardous materials and mixtures for the diploma written assignment on the topic of "The Transportation of Hazardous Materials and Mixtures on the Territory of the Czech Republic" there was a quantitative research made. The quantitative research was made with the help of handed out questionnaires. The public was represented by the employees of the Regional Municipalities of the Czech Republic. Both of the groups were given the same questionnaires. The results of the questionnaire research were evaluated, expressed in percentage and statistically assessed. For the statistical assessment the double selection T-test was used to find out whether the difference between the assessed groups is statistically important. People working in the transportation of hazardous substances and mixtures have sufficient information which was confirmed by the questionnaire research. By the made statistical assessment it was found out that the difference between the groups is statistically significant and so the public does not have sufficient information related to the transportation of hazardous substances and mixtures. Due to the results of the questionnaire research and mainly that the hypothesis b) - The public has enough information about the transportation of hazardous chemical substances or mixtures was not confirmed. In the conclusion of the written assignment there are a couple of suggestions for improvement of the awareness of the public. For example as a part of education at primary and high schools and training schools where this education is already running as a part of The Protection of Human during Incidents. This education has been going on since 2003. And that is why the older people in the public are not well met with this issue and they should be introduced to it by for example a media campaign by means of short TV spots on public television channels or by means of spots that already the Independent BESIP Department of the Ministry of Transportation makes up. These spots are called Besipky.

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.

ELECTRON BEAM REMELTING OF PLASMA SPRAYED ALUMINA COATINGS
Matějíček, Jiří ; Veverka, J. ; Čížek, J. ; Kouřil, J.
Plasma sprayed alumina coatings find numerous applications in various fields, where they enhance the properties of the base material. Examples include thermal barriers, wear resistance, electrical insulation, and diffusion and corrosion barriers. A typical structure of plasma sprayed coatings, containing a multitude of voids and imperfectly bonded interfaces, gives them unique properties - particularly low thermal conductivity, high strain tolerance, etc. However, for certain applications such as permeation barriers or wear resistance, these voids may be detrimental.\nThis paper reports on the first experiments with remelting of plasma sprayed alumina coatings by electron beam technology, with the purpose of densifying the coatings and thereby eliminating the voids. Throughout the study, several parameters of the e-beam device were varied - beam current, traverse velocity and number of passes. The treated coatings were observed by light and electron microscopy and the thickness, structure and surface morphology of the remelted layer were determined and correlated with the process parameters. Based on the first series of experiments, the e-beam settings leading to dense and smooth remelted layer of sufficient thickness were obtained. In this layer, a change of phase composition and a marked increase in hardness were observed.\n

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.

Food supplements and iodine supplementation breastfeeding women
IVANOVÁ, Markéta
Iodine is a trace element that is essential for the production of thyroid hormones triiodothyronine and thyroxine. Iodine deficiency had in the past result in many serious diseases and disorders. At present is in the Czech Republic considered mastered. However, Iodine deficiency are vulnerable to specific groups of the population, including pregnant and nursing women, because of their need and the recommended daily dose of iodine is increased. Breastfeeding women should receive adequate amounts of dietary iodine for optimal saturation for themselves and their child. Otherwise, exposing themselves and their child risk of diseases and disorders of iodine deficiency. Increased supply of iodine can be replaced by eating foods rich in iodine. In the event that you cannot increase intake of iodine - rich food preferences in iodine, there are various supplements that contain iodine. The aim of this thesis was to evaluate the intake of iodine supplements and supplements in nursing women and breast-feeding women to assess the awareness for greater needs of iodine and food iodine sources. There were set up the three research questions: How many nursing women used to supply iodine supplements and supplements?, What is the awareness of breastfeeding women need more iodine? and What is the awareness of breastfeeding women about dietary sources of iodine? A quantitative research strategy was used for the implementation of the research. The method used for data collection was made by an anonymous questionnaire. A questionnaire was handed in a printed copy to pediatricians and gynecologists in the southern Bohemia. With the doctors help were invited nursing women to fulfill the questionnaire. Part of the women was invited to complete the questionnaire directly. The research sample consisted of 117 female respondents. The research shows that 62 % of breastfeeding women know why it is important to increased need for iodine during lactation. But only 9 % of women know all the risks of iodine deficiency on the mother mentioned in the questionnaire and only one new mother knows all risk of iodine deficiency for infants listed in the questionnaire. The recommended daily intake of iodine properly reported or estimated 40.2 % of women. It turned out that 46 % of respondents from the research group used food supplements and supplements containing iodine. Each of these respondents used only one preparation with iodine. The most commonly used products were: GS mamavit, a Smart baby and Femibion 400 and Gravital. 43 % of respondents had used a dietary supplement containing iodine from the beginning of pregnancy and in 57 % of the respondents were informed about food supplements through a doctor (gynecologist, pediatrician). The results showed that awareness of breastfeeding women about food sources of iodine is not good. 67 % of women know that settlement higher needs iodine during lactation is possible by eating foods rich in iodine, but all food sources of iodine in the questionnaires (sea fish, seafood and seaweed, iodized salt, and milk and dairy products) registered only one respondent. 39 % of women known as a rich source of iodine, seafood, seafood and seaweed, iodized salt , but none of them knew that the rich and a good source of iodine is also milk and dairy products. Based on the results of the work would be desirable to issue educational print disabled educational material that could be used to increase awareness of not only women who are breastfeeding, pregnant women as well as the higher of the recommended daily dose of iodine and what foods to include in your diet in order to pay the increased intake of iodine. Provide information on supplements containing iodine, which can add missing quantities of iodine, what products are available and what are the currently preferred by nursing women.

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.
