Woman´s Clothing Factory
Kovářová, Hana ; Štikar, Jaroslav (referee) ; Nový, Alois (advisor) ; Donaťáková, Dagmar (advisor)
The women´s clothing factory is situated in the city part Brno-Židenice in the area of one so called „brownfields“. Currently there are rusty storages and old garages standing in the building ground. The site is bordered by several streets – it is Rokytova street, Komprdova street and Údolíček street – and the fourth side is closed by boundaries of a cemetery. The area can be entered from the north-west street Údolíček. According to the ground plan, its location is temporary, so we changed it a little to better match the needs of the company. The entrance for pedestrians is situated at the north-west too. And there are also parking places and other necessary manipulation space situated on the grounds. The clothing factory is aimed at production of Giorgio Armani´s women confection so the architectural solution is based on the basic philosophy of the company. Their models are famous for their simple design with a patterned fabric that make them special. So the basic mass of the object is a simple block, which is sensitively placed at the surrounding landscape and which is made special by the parts of ovals that are embedded or comming out of the basic mass. These parts of ovals create both – resting and functional spaces. The strong horizontal character is broken by a cylindrical body stucked into the basic shape that surmounts the block by one floor. A big part of the production hall is glassed-in so we can get enough light into the interier and the employees can be in touch with the surrounding. There is a facade net strunged in front of the glass facade. The net limits overheating and also plays the role of the unifying element. The building integrates a producion hall, storages, sanitary rooms, administrative space, canteen with affilated spaces and energy traffic necessary for running the factory. The wing cell is a steel skeleton combined with reinforced concrete circumferential wall and tie brick walls.

Ivanova, Nadezda ; Navrátil,, Aleš (referee) ; Nový, Alois (advisor)
The object consists of 3 volumes: two 6-storey academic buildings, interconnected with public space. Simple geometry of complex is formed by the existing urban development. Repeating street directions and continuing visual contact with the housing of the Law Faculty, the building in terms of shape represents letter V and forms enclosed courtyards. In the lower part of the building of the Faculty of Fine Arts there are workrooms, library and repository that are loaded from the north facade. The first three floors are connected by a corridor with a recreational area of public space created for a comfortable communicating and solitary classes. On the other floors there are workshops, studios and studio offices of ceramics, sculpture, metal, photography, printing and 3D-graphics, cabinets of deanery and classrooms. On the top floor, that is 6 m height, there are art studios, additionaly lightened by lanterns on the roof. The housing is designed in that way that it has the open airy atrium, which, along with half-transparent facades, provides natural light in most interiors. Facade structure is highlighted with the shell of the vertical and horizontal aluminum fins and shelves, which gives to a compex an interesting and constantly changing pattern. Unified composition is also highlighted with shades of warm and cold colors of the spectrum. Four underground floors are used for car parking, and the ground flloor of them is given for the operation of the university. In the future, the project also envisages planting of greenery of building facades and of the surrounding area.

Analysis and modeling of the structure and development of mixed forest stands in the Sudety mountains
Vacek, Zdeněk ; Remeš, Jiří (advisor) ; Hlásny, Tomáš (referee)
The thesis deals with analysis and modeling of the structure and development of selected mixed forests in protected areas of the Sudeten system, especially in the Giant Mountains national parks, Protected Landscape Area Broumovsko and Orlické Mountains, but also in other areas of the Czech Republic. This study is composed of a set of six published manuscripts that are covering three thematic ranges: structure of forest stands, regeneration of forest stands and forest modeling. The main objective of this work was to evaluate a vertical, horizontal and species structure, total diversity and development of mixed forest stands in central Sudetes. The partial aim was to analyse production parameters of forest stands, effect of microrelief and game on natural regeneration and assessment of dead wood in the area of interest. Further, the objective of the study was to develop explicit and non-explicit crown width and slenderness quotient models for Norway spruce (Picea abies L.) and European beech (Fagus sylvatica L.) and to predict the development of mixed forest ecosystem using growth simulations and to evaluate parameters and interactions among stand structure, climatic factors and natural regeneration, using especially analysis of variance, correlation matrix, spatial statistic and multivariate analysis. For this purpose a system of permanent research plots was used, which are regularly monitored since 1980 or were newly established. Using mapping technology FieldMap, selected parameters were measured for tree layer, natural regeneration individuals and dead wood. The results showed that the spatial distribution of beech stands in optimum stadium changes with the altitude from the regular pattern through random to aggregated spatial pattern of beech forests near the timberline. The spatial distribution of natural regeneration is highly aggregated, distribution of stumps is random and horizontal structure of the centroids of the crowns is always more regularly distributed than stems due to crown plasticity. Browsing damage of the leading shoot by game is an important limiting factor for height growth of natural regeneration, especially for silver fir (Abies alba Mill.), rowan (Sorbus aucuparia L.) and sycamore maple (Acer pseudoplatanus L.). The study of the influence of microrelief on the growth of beech regeneration showed that the highest average height was found on slope and pits, while the lowest on the mounds. From the effect of climatic factors on the radial growth of trees, it was found that temperature is a limiting factor for growth in mountain areas, respectively that positive effect of temperature decreases with decreasing altitude and conversely the influence of precipitation increases. Finally, spatially explicit models (as opposed to non-explicit) described a larger part of the crown width variations for spruce and beech and of the slenderness quotient for spruce. The largest contribution to the models after breast diameter was dominant height.

Þorr's voyage to Geirrøðr
Kozák, Jan ; Antalík, Dalibor (referee) ; Starý, Jiří (advisor)
The thesis analyzes eight versions of a narrative of thórr's journey to the dwelling place of thurs (giant) Geirrodr. These variant versions are preserved in several distinct genres and come down from different ages - the oldest is a scaldic poem from the time before the christianization of Scandinavia (10th century) whereas the other versions are written down by Christian Icelander Snorri Sturluson and Danish chronicler Saxo Grammaticus (both 13th c.). The youngest version is a fairy-tale short story from 15th c. The fact of diachronic and genre variation is used to track and analyze the changes of an originally religious narrative after the christianization, i.e. after the dissolution of the original pagan symbolic universe into the medieval (or even post-medieval) one. Although the basic pattern of the story and the names of the protagonists are preserved quite well (in respect to the time span and indirect transmission), the meaning and genre setting of the story is significantly altered: in the case of Saxo Grammaticus into euhemerized pseudohistory and in the case of 15th century short story into fairy-tale loosely connected to historical king Ólafr Tryggvason. This observation illustrate and confirm the process of demythization of pagan myths and show two genres where those myths are to be "stored"...

Unintended impoliteness of Czech speakers in English. A Czech-English contrastive study
Vokurková, Iva ; Klégr, Aleš (advisor) ; Šaldová, Pavlína (referee)
In the world of today, cross-cultural interaction takes place every day at many levels of our lives, be it a study stay abroad, work, migration or simply a holiday. The world is getting more and more interconnected, the term "global village" is today more true than ever and with globalisation and European Union integration people from various parts of the world and with various cultural backgrounds are brought together and interact in one way or another. However, communication, although having a number of universally applicable features, is culturally (as well as socially, etc.) determined and therefore it is of great importance to the interactants from culturally different backgrounds to keep this fact in mind and be constantly aware that in different cultures people can be accustomed to achieving the same ends by using different linguistic (and other) means. The field that studies the differences as well as similarities between linguistic means and communicative patterns of different languages is called cross-cultural pragmatics. Its outputs and conclusions help to detect the pragmatic sources of miscommunications as well as bring a new perspective on the languages and cultures in question. This knowledge proves useful not only in foreign language classrooms but in all sorts of situations to all kinds of...

Plazmochemická příprava olovnato-wolframové bronzi
Brožek, Vlastimil ; Janča, J. ; Eliáš, M.
Tungsten bronzes are materials based on tungsten oxide that exhibit different colours, excellent chemical resistivity, metallic appearance and good conductivity. The doped tungsten bronzes may by used as anodic catalyst in fuel cells. The tungsten bronzes are prepared by reduction of tungstates. The reduction process is known for very long time, but the correlation between their stoichiometry, conductivity and colour are not yet completely understood. The published results about colour of products are very often misleading. In this paper, we study chemical reactions between lead-tungstate and hydrogen plasma. The reduction was performed in an inductively coupled r.f. discharge. The r.f. generator operated at the frequency of 27 MHz with the power output of 1 kW. The PbWO4 was heated by the discharge to the temperature of 900°C. The resulting samples were analysed by SEM, XRD and three point L*a*b* method. The XRD spectra of our plasmachemical product show diffraction patterns of metal tungsten and lead-tungstate bronze with a cubic phase similar to Pb0,261WO3 (P4/mbm). The diffraction peaks of original lead-tungstate bronze are higher for the sample reduced only 60 min than for 120 min. To obtain data for process kinetics observation, further experiments were performed with ground lead-tungstate powder at two size fractions. Analytical balance, after determining the W and Pb content, showed the bronze composition to be most likely close to Pb 1-X = 0,225.

Research between students of selected high schools inside and outside the emergency planning zone of the Dukovany nuclear power plant in field of population protection
KOLÁŘOVÁ, Helena
Spectrum of threat types and their combination is very extensive. The essence remained for chiliads unchanged, but during the development of mankind some patterns extinct or changed their shape, other reappear. Efficient managing of emergency situations requires beside this competent specialists, organizations, systems and legislative regulations and also ready and well-informed population. Principal part of knowledge and skills in the field of inhabitants protection and behavior in the emergency situation acquire the kids on the primary and secondary level of education. This object is included in the education on the primary and secondary schools according to Instruction of Ministry of Education, Youth and Sport about the integration of the subject of protection of man in a emergency situation into the education program, r. n. 13 586/03-22, and the related appendix to the educational documents "Protection of man in emergency situations", r. n. 13 586/03-22 of the 4. march 2003. Education proceeds to the extent of at least 6 lessons in every class, most often cross-sectional within the selected school subjects. Very important role in the education of inhabitants plays Fire Rescue Service of the Czech Republic. This master thesis focuses as one of its main goals on the inquiry of the knowledge and opinions of the selected age group of 15 to 20 years old related to the behavior in the emergency situation and to the knowledge of the integrated rescue system. Another goal was to find out, if the results of the inquiry are influenced by the fact, that the school and permanent home of the student is situated within or outside the emergency planning zone of the Dukovany nuclear power plant (EPZ Dukovany NPP). The theoretical part focuses mainly on the development of the education of children and youth in the field of protection of population after 1991 and on the contemporary system of education in the field of protection of man in emergency accident on professional and grammar schools. In the experimental part of the thesis two hypothesis were set. According to H1 should at least 75 % of the students correctly answer more than half of the questions. H2 was divided into two partial hypothesis, whereas it was supposed, that between the informedness of the students of grammar schools resident and studying within EPZ Dukovany NPP or outside EPZ Dukovany NPP and the students of the professional schools resident or studying in EPZ Dukovany NPP and outside EPZ Dukovany NPP these is no statistically significant difference. Presented data were acquired on the chosen schools within and outside the EPZ Dukovany NPP in the form of questionnaire survey. Questionnaire was set together from four questions of qualitative nature and 16 questions of quantitative nature. On the grounds of the measure data it was necessary to reject the hypothesis H1, since only 21,5 % of the students answered correctly more than a half of the answers. The average achievement in the questionnaire was 41,3 % of correct answers. In the testing of parametric hypothesis was by means of comparison of the selective statistical sets proved, that the informedness of the students of both types of secondary schools is on the same level and further that there is no significant statistical difference between the informedness of grammar school students living in and outside the EPZ Dukovany NPP. The hypothesis H2 was thereafter confirmed. The results imply, that the informedness of students in the field of the protection of population is insufficient. As a suitable solution of this problem appears the education of these topic within a separate subject focused on the protection of man.

Dubroková, Jitka ; Mihaljevič, Martin (advisor) ; Strnad, Ladislav (referee) ; Chrastný, Vladislav (referee)
110 Summary The study of biogeochemical cycle of rare earth elements (REE) carried out in the Lesní potok catchment and its vicinity (located in the Nature State Reserve, Voděradské bučiny, 30 km SE of Prague) was focused on the monitoring of REE concentrations and distribution patterns in natural environment, their relationship with other analysed elements and compounds such as Al, Ca, Fe, K, Mg, Mn, Na, P, S, Si, F- , Cl- , NO3 - SO4 2- , HCO3 - and organic carbon, and its response to physicochemical conditions in various investigated ecosystem compartments. The samples of soil, stream sediment, stream and ground water, rainwater and throughfall in beech and spruce forest, samples of tree assimilatory organs, bark and stem wood of Norway spruce (Picea abies) and European beech (Fagus sylvatica) and lichens (Hypogymnia physodes) were collected in the catchment and its vicinity. Liquid samples were acidified with dilute nitric acid to prevent losses by adsorption, and filtered using a 0.45 µm membrane filter. Stream water samples sampled in months characterized by low and high discharge were processed by ion exchange chromatography and membrane dialyses. Solid samples were dried to constant weight (and sieved and homogenized in case of soil stream sediment samples) and decomposed in the microwave oven with...
