Water retention capacity of humic substances
Cihlář, Zdeněk ; Šmejkalová, Daniela (referee) ; Kučerík, Jiří (advisor)
Humic acids were extracted from South Moravian lignit. That humic sample was oxidized by either H2O2 or HNO3. In next step, oxidized humic acids were polymerized by formaldehyde in order to obtain cross-linked structures with improved water retention capacity. Affinity to water and water retention capacity of obtained products were studied by thermal analysis (DSC – differential scanning calorimetry and TGA – thermogravimetric analysis). In order to study above-mentioned parameters two different methods were used. First approach represented sorption of water to humic acids from three controlled humidities, for description of those processes TGA measurement was used. Second study was based on the DSC monitoring of water excess sorption. Results obtained from TGA measurements showed an increasing sorption ability with increasing relative humidity of the environment. DSC measurerents in hermetically sealed containers resulted in an increasing content of water bound by humic acids structures. All the modified samples of humic acids (oxidized as well as oxidized and modified by formaldehyde) gave higher retention capacity in comparion with the parental humic sample.

Questions about the usage of the preposition "po" in Russian literature
Hlaváčková, Martina ; Liptáková, Zuzana (advisor) ; Nazarenko, Liliya (referee)
"The questions about the meaning of the preposition "no" in Russian literature" The tendered diploma work is focused on issues of the relations sense mediated by the preposition no in fiction and on the options of its translation. It is my intention to compare the occurance frequence of the separate meanings in constructions with no in fiction of 19. and 20. century. The theoretical part deals with the information from the scientific literature related to prepositions and and typical qualities of no itself. Special attention is dedicated to its mening. What concerns the practical part, there is a suggested process for gaining and processing of the material exempted of the texts on the first place. On its base the picked pieces of fiction are analysed. The gained results are evaluated, compared and completed by a comment. According to the analyzed stuff it is clear that the meaning of the preposition no depends on the text character. Also the options of the translation are linked with that.

Firm culture and its influence on motivation of firm's workers.
Zika, Jiří ; Kuchař, Pavel (advisor) ; Tuček, Milan (referee)
Bc. Jiří Zika Abstract The Diploma Thesis deals with the subject of firm culture and its influence on the motivation. It is focused especially on the analysis of firm culture and on the influence of firm culture on motivation. In this time is firm culture relatively well established field, and so this work is trying to point out the major approaches of firm culture. It analyses the known theories of motivation and then it deals with the links of firm culture and motivation. The influence of firm culture on motivation of workers working on business license is examined in the company, which deals with selling of real estates. This influence is being described especially by the influence of the elements of firm culture on the complete motivation and on different aspects of motivation as well. This work in its final form brings the reader an integrated view on firm culture, motivation and their interrelationship. It is focused especially on the influence of firm culture on motivation. The results of this work bring the information, that even under the conditions which are not favourable for firm culture it is possible to work relatively well on firm culture and its enforcement across the firm. These results go out from the combination of quantitative and qualitative methods. The research was based on the...

The quality of furniture in the context of the brand Czech quality furniture
NOVÁK, Tomáš
The diploma thesis deals with the analysis of the qualitative level of furniture available on the Czech market in the context of quality labels. The most important mark of quality for the section of furniture is a brand of Czech quality, furniture, which is a central issue for this work. Introduction of thesis is dedicated to the theoretical analysis to ensure a closer acquaintance with the true issue. Continuing practical part of the thesis is devoted to the analysis of the quality of the furniture present on the Czech market, which was carried out by means of questionnaires. Addressed were primarily manufacturers of furniture, who do not possess the marks, and consumers. For obtaining the third were referred to research supplemented by the investigation carried out by the technical services of accredited for the testing of furniture. The outputs obtained from the questionnaires were linked in the form of a synthesis of the data which describes the current situation in the section of furniture on the Czech market. After analytic-synthetic part followed the discussion, which was created with the use of study Furniture 2010 published by INCOMA GfK. The last part of the work is result, which was primarily intended to confirm or refute the hypothesis set out, where applicable, to the summary of the most important knowledge related to the quality of the furniture on the Czech market.

The role of radiological assistant during the examination of thyroid gland by methods of nuclear medicine
Ujhelyiová, Alena ; Vlček, Petr (advisor) ; Táborská, Kateřina (referee)
The topic of this paper is the examination of the thyroid gland by utilizing the methods of nuclear medicine. Its primary focus is on activities of the radiologist assistant in the course of such examination. In the introductory chapter, the paper explains the scope of nuclear medicine. The second chapter addresses the fundamental anatomy of the thyroid gland. Specifically, it describes the common form, placement, size and mass of the thyroid gland, its elemental parts, structure, function and basic physiological processes. The chapter on clinical picture describes the most common diseases linked to the thyroid gland. The frequency, incidence and causes of such diseases are addressed. The fourth chapter addresses the application of nuclear medicine methods in thyroidology. It describes how the application of nuclear medicine has evolved in time and how nuclear medicine and its methods are applied at present. The opening section of the fifth chapter describes the requirements of the basic legislative document governing peaceful applications of the nuclear energy, the socalled Atomic Law. Further, scintillation camera and its parts are described in this chapter as the most common visualization apparatus. The chapter on examination addresses the basic classification of examination procedures. The thyroid gland...

Lexical bundles in academic lectures
Leško, Marek ; Klégr, Aleš (referee) ; Malá, Markéta (advisor)
Lexical Bundles in Academic Lectures (BA thesis abstract by Marek Leško) The work attempts to briefly outline the current state of knowledge on the subject of lexical bundles and investigate their functions and use in two sets of academic lectures, British and American. For this purpose, it uses lecture transcripts from BASE (British Academic Spoken English) and MICASE (Michigan Corpus of Academic Spoken English) corpora. In the theoretical part, lexical bundles are defined as recurrent expressions of three and more words that are identified by statistical means (at least 20 occurrences per million words, for instance) only with no regard for structural completeness or perceptual salience. The work presents general characteristics of lexical bundles as typically non-idiomatic, structurally incomplete units and sorts them into several structural categories typical of conversation or academic prose. Three main functions of lexical bundles are identified: stance expressions, discourse organizers and references. Finally, the study discusses lexical bundles in terms of cohesion, i.e. how these recurrent expressions are used as surface links within the discourse to signal mostly intrasentential relations that fulfill the role of linking adverbials. In the practical (research) part, the thesis presents data...
