New learned compound elements in French
DAŇKOVÁ, Ivana
The topic of this thesis is "New confixes in French". This thesis is divided into two main parts: theoretical and analytical. The first part is theoretical and describes the historical development of "confixation" (learned compounding) as well as different theories and approaches to the word formation process. This part also defines "confixation" to other word formation processes (derivation and composition) and the structural component of "confixation" - a "confix". The second part is analytical and deals with specific learned stems (confixes) and learned compounding. The study material for this part of the thesis has been gained by the data excerption from the corpus Sketch Engine. The sample excerpted from the corpus is the subject of the analysis. The analysis focuses on the classic and modern confixes and their typology: classification of confixes according to the position in the learned compounding, or according to the origin, etc. The analysis also treats the morphological categories of learned compounding and their internal structure. The main focus is drawn to modern confixes that were created mostly by the change of meaning of the classic confix. This part deals with the newly created confixes in French that do not have the direct Greek or Latin base. These are mostly loanwords from English. The main aim of present thesis is to identify newly created confix compounds in comtemporary French.

Characterization of bacterial genes encoding DbtC-like extradiol dioxygenase with bioremediation potential for aromatic compounds in locality Hradčany
Šnajdrová, Renata ; Bořek Dohalská, Lucie (advisor) ; Nešvera, Jan (referee)
Aromatic pollutants pose a serious environmental problem. Petroleum and its derivates belong to the most abundant contaminants in the Czech Republic and their sanation is a priority objective for improving the life quality of the population. Bioremediation is a technology taking advantage of the natural capacity of soil and water microbial community to degrade environmental pollutants. Deeper understanding and detailed knowledge on specialized bacterial species, pathways and genes is required for selection, optimization and application of targeted bioremediation approach and for monitoring of its results. Recent analysis of a metagenomic library constructed from highly contaminated soil of the former military air-base Hradčany has identified a novel group of catabolic genes encoding extradiol dioxygenase similar to DbtC of Burkholderia sp. DBT1. The DbtC-like enzymes are among the three priority groups of extradiol dioxygenases with biodegradation relevance for the locality. The present study of soil bacterial isolates and metagenomic fosmid clones harboring the genes of interest gained evidence about the dbtC-like genes as a part of highly mobile gene cassette. Transposon insertion mutagenesis identified the genes joined with the expression of the extradiol dioxygenase activity. The dbtC-like genes were...

Thin-film geopolymeric plasters for exterior application
Ručková, Jana ; Opravil, Tomáš (referee) ; Šoukal, František (advisor)
This thesis is dealing with preparation of exterior thin-layer geopolymer plaster where the effect of supplement of various types of superplasticizers in their different amounts on the quality of geopolymer plaster is studied. The objective of this work is to determine suitable type of superplasticizer which would improve rheological quality of fresh plaster mix, its adhesion to the surface and last but not least would preserve good mechanical qualities of geopolymer binder. In the experimental part initially test subject were prepared from meta-kaolin, water, water-glass, sand and with supplement of various types of superplasticizers in various amounts. These test subjects were tested for compressive and flexural strength. Further workability and adhesion to the surface of these plaster pastes was observed. Geopolymer pastes were also subjected to calorimetric comparison of kinetic processes occurring during solidification and hardening. In order to identify the exact composition of superplasticizers used as rheological modifiers, the infra-red spectrometry of these substances was performed. There was a need to specify the water-glass in more detail as well, elemental analysis was performed on it on radiographic fluorescent spectrometry. To closer identify the structure and distribution of superplasticizer in geopolymer paste the pictures of the mix which was the most suitable for use for exterior thin-layer geopolymer plasters were made on scanning electron microscope. On the same mix radiographic diffraction on the powder samples was also performed which served for phase analysis.

Magnetic properties of Ce compounds studied by specific heat
Čermák, Petr ; Javorský, Pavel (advisor) ; Havela, Ladislav (referee)
Materials containing the 4f (rare earth) or 5f (actinides) exhibit a large variety of interesting physical properties. The Ce-based compounds have a special place among the rare-earth compounds. The Ce atom contains only a single f-electron that is responsible for the magnetic behavior. The 4f states in compounds with the heavy rare earths have a well localized character, whereas many Ce-based compounds are on the borderline between the localized and itinerant behavior. These compounds show large variety of the magnetic ground states what is a result of the competition between the long-range order of the RKKY type and the screening of the localized moments by conduction electrons. We observe nonmagnetic states with a mixed valence (between Ce3+ and Ce4+), metallic systems with a long-range order of the Ce moments (ferromagnetic, antiferromagnetic or more complex structures). To analyze the electronic properties, the heat capacity data, and namely their low-temperature part, play an indispensable role. This diploma work comprise the sample preparation of selected cerium compounds, their phase characteristics and the heat capacity measurements at low temperatures (0.4 - 300 K). The main part is focused on the data analysis and comparison with theoretical models.

Interconnection between labor market and monetary policy: NAIRU, unemployment hysteresis and monetary policy responses
Slaný, Martin ; Tomšík, Vladimír (advisor) ; Mandel, Martin (referee) ; Žák, Milan (referee)
This dissertation thesis deals with relation between labour market and monetary policy referring to two fundamental theoretical concepts -- natural rate hypothesis (or NAIRU) and unemployment hysteresis hypothesis. The first chapter outlines the most frequent values of the Phillips curve, the fundamental model of macroeconomics theory in the relation between the labour market and the monetary policy. The following chapter deals with the exogenous NAIRU concept which works as natural unemployment rate approximation. The unemployment hysteresis deals with the NAIRU as endogenous variable which is dependent on preceding imbalanced situations on labour market. The thesis outlines the main causes of the hysteresis: capital scrapping effect, role of the long-term unemployment and the insider-outsider hypothesis. The third chapter also comprises simple econometric tests of both particular mechanisms and the hysteresis itself based on usual unit roots tests. The results show the hysteresis using data from both the Czech Republic and Central and Eastern Europe countries (CEEC). The fourth chapter deals with monetary-political implications of the unemployment hysteresis. The practical part of the thesis is based on two hypotheses of the relation between inflation (policy interest rate) and NAIRU. The last chapter based on the VAR model outlines short-term relations between the labour market and monetary policy variables. Long-term relations are tested by both the co-integration analysis and vector error correction model (VECM). These models are examined on the data from the Czech Republic and Poland (2000-2013). The thesis also applies pooled regression estimate for ten CEEC. The results show that the monetary policy does have impact on the labour market not only in the short-term but also in the long-term period and thus they confirm the hysteresis hypothesis

Alcohol-free beers with herbal extracts
Vyskočilová, Terezie ; Lichnová, Andrea (referee) ; Márová, Ivana (advisor)
This bachelor thesis deals with alcohol-free beers and herbal extracts, which are the beers flavoured with. In the theoretical part the methods of non-alcoholic beer production and the representation of the active ingredients in herbs are described. A total of 7 herbal extracts were prepared and added into 3 non-alcoholic Czech beers. Each variant was examined in order to detect changes of the content of active substances before and after the addition of the herbal extract. The content of polyphenols, flavonoids, bitter substances and iso-bitter acids as well as antioxidant activity were analyzed spectrophotometrically. Using HPLC/UV-VIS analysis a content of catechins was assayed. The two selected flavours were encapsulated into liposome; the particles were tested of size and stability. Sensory analysis of all herbal extracts including the encapsulated ones was performed to determine the response of consumers and flavour preferences.

Bokrová, Jitka ; Skoumalová, Petra (referee) ; Márová, Ivana (advisor)
The aim of this bachelor thesis was to study physiological effect of various kinds of lager beer and to compare these effects in Czech beer and several beers produced in foreign countries. In theoretical part Czech beer characteristics and biologically active compounds in beer are described. Quantification of total phenolics, total flavonoids, antioxidant activity and bitter substances was performed photometrically. The quantity of vitamin C was determined by high performance liquid chromatography with spectrophotometrical detection. Beer buffering capacity was analyzed by pH measurement in artificial stomach and intestinal liquid, respectively. Analysis of physiological effect was accomplished by analysis of proteolytic enzyme activity. The total of 22 samples (16 Czech and 6 foreign lager beers) was studied. In these samples levels of basic technological characteristics and buffering capacity were compared. Alcoholic and non-alcoholic beers were compared too. According to experimental data it was confirmed that consumption of Czech beer (mainly lager beer) positively influences digestion process and activity of digestive proteolytic enzymes.

The specifics of CT and MR examination in children
NOSKOVÁ, Kateřina
The bachelor's work deals with specifics of examining children by mean of computed tomography (CT) and magnetic resonance imaging (MRI). Radiological imaging methods CT and MRI are irreplaceable for exact diagnostics of all kinds of diseases and form an integral part of modern paediatric radiology. What is important is not only technological equipment of high quality and specific procedures, but also a professional approach of the medical staff that carry out an intervention. The goal of the work is the provision of basic information about CT and MRI methods, the accent being on child patients, and the description of the course of the above-mentioned examinations in children. Another goal is to analyze specifics of individual examinations. The staff should act professionally as working with children requires a fair amount of patience and understanding. The capability to explain, as easily and effectively as possible, to the parents and the child how the examination will go on is no less important. The examination must be carried out as quickly as possible and the chosen examining method must bring a result of sufficient quality. While being examined, the patient is required to stay at rest in bed, which is a frequent problem in little patients. The theoretical part is divided into a few chapters. Individual chapters describe individual imaging methods and their advantages and disadvantages. Furthermore, there is an overview of contrast agents there, their classification and possible undesirable effects. A chapter on paediatric anaesthesiology is not missing either the knowledge of this area is often very important, especially when examining children under 5 years of age, claustrophobic patients or very restive children. The aim of the practical part of the work was to evaluate the information the parents have on the examination that was indicated to their child (CT/MRI). To that end, a questionnaire was developed, which was available at the Clinic of Paediatrics of the Motol Teaching Hospital (Clinic of Imaging Methods) and in the Brno Teaching Hospital (Clinic of Paediatric Radiology) and contained 25 questions in all. Answers to the questions could have been marked with a cross, elsewhere free answers were possible. Furthermore, data on the number of children examined by means of CT and MRI methods at clinics of paediatrics existing with hospitals having special paediatric radiodiagnostic departments (Motol Teaching Hospital Clinic of Imaging Methods and Brno Teaching Hospital Clinic of Paediatric Radiology) between 2010 and June 2015 was analysed. The data analysed was divided into a few age categories, as per specific needs of the child. The analysis of the data should have helped answer research questions to what extent the parents were informed of the course of the examination of their child and whether the number of children examined by means of CT and MRI methods was increasing. In order to answer the research questions, data from the clinics of paediatrics having special paediatric radiological departments (Motol Teaching Hospital Clinic of Imaging Methods and Brno Teaching Hospital Clinic of Paediatric Radiology) was utilized, as well as the completed questionnaires. The chapter "Results" shows, with the help of graphs, answers to the questions from the questionnaire investigation and the data acquired in the Motol Teaching Hospital (Clinic of Imaging Methods) and the Brno Teaching Hospital (Clinic of Paediatric Radiology). In the chapter "Discussion", the results of the questionnaire investigation and the data acquired are evaluated. The work and its results can be utilized by other radiodiagnostic departments, or they can serve as supplementary material or material of advice for parents and students.

Dynamic modification of proteins for fluorometric detection in CZE
Horká, Marie ; Šlais, Karel
The separation techniques employing fluorescence detection are sensitive and selective so they have been often applied for the trace analysis of biological samples. The commonly used derivatization of proteins can lower the detection limits; however, they can change the acido-basic properties and mobilities when compared to the native species. Recently, we have used the colored tenside as a buffer additive for the photometric detection of proteins in the UV region. The selectivity, efficiency and resolution of CZE separation using this dye were found to be similar to the CZE with SDS as the additive. In this study, the ampiphilic fluorescent compound is suggested as a buffer additive in CZE for dynamic modification of the sample of several proteins. Using the deuterium lamp for the excitation in the UV region for the on column fluorometric detection, the amol minimum detectable amounts of the proteins sampled on the CZE capillary were achieved.
