The Fruit Beers Popularity in the Czech Republic
Balaštík, Milan ; Maier, Tomáš (advisor) ; Lukáš, Lukáš (referee)
The main topic of this thesis is the popularity of fruit beers in the Czech Republic. It describes a generic distribution of fruit beers, both abroad and in our country. Shows an overview of large and small manufacturers in this category in the domestic market. It focuses on the current situation flavored beer on domestic and foreign markets, according to the latest data. Based on the survey are analyzed consumer preferences in the domestic market. They are then formulated breweries general recommendations arising from the outcomes of the survey. Subsequently, using basic statistical methods detected significant correlation between the consumption of flavored beers and gender and between consumption and age of respondents. If so, then it determines the strength of this dependence. It was found that while significant correlation was demonstrated in sex exists between consumption and age of the respondents. The strength of this dependence was assessed as moderate. It was finally drafted forecast consumption of mixed drinks based on beer in the Czech Republic. The analyzed time series contained the actual annual data maintained by the Czech Beer and Malt Association from 2012 to 2015. The forecast was calculated for the next two years. It was found that consumption of mixed drinks based on beer in the future will continue to decline.

Impact of the troposphere on the inosphere
Koucká Knížová, Petra ; Mošna, Zbyšek ; Potužníková, Kateřina ; Boška, Josef ; Kouba, Daniel
Ionosphere represents weakly ionized plasma that reflects solar and geomagnetic activity and processes\nin the neutral atmosphere. Correlation of long time series of the ionospheric plasma critical frequencies,\nobtained by mean of vertical sounding from European stations, is analysed with respect to latitudinal and\nlongitudinal difference and surface distance of stations. Time series of critical frequencies are highly correlated\nreflecting the dominant solar influence. Correlation coefficients are high not only for raw data and subtracted\nmean courses but for fluctuations around mean as well. At the surface distance exceeding 1000 km and/ or about\n10 degrees of latitudinal difference between stations, the correlation coefficients of fluctuations decrease\nrapidly. Such effect is less visible on the latitudinal dependence, where the correlation coefficients decrease with\nincreasing distance with less pronounced threshold. We explain the existence of the ‘break point’ at 10 degrees\nin longitude and/or 1000 km by the ‘local’ influence of the neutral atmosphere and the wave activity. As a\npossible source of the common influence on scale 1000 km/10 degree we propose tropospheric systems that are\nknown to be an important source of atmospheric waves in a broad period range. Large tropospheric mesoscale\nsystems have typically up to 2000 km in size.

Detection and localization of cyanobacterial inoculum in the sediments - use knowledge of life strategies to minimize health risks
Šejnohová, Lenka ; Maršálek, Blahoslav ; Novotná, Zlatica ; Maršálková, Eliška
Water bloom (WB) is a global problem that is particularly closely linked with increased inputs of phosphorus to surface waters.. The subsequent accumulation of nutrients in the tank for the development not only of cyanobacteria in the water column, but also their survival in resting stages in the sediment. The quantity (amount) of inoculum (source) of cyanobacteria in the sediments is the primary factor, along with nutrient and climatic conditions, correlates with the resulting amount of algae in the water column during the summer season. Cyanobacterial resting stages in sediments require specific conditions for survival, which moreover genus from the genus (or species), cyanobacteria differ. Knowledge of the life cycle of cyanobacteria is therefore an essential prerequisite for starting a guide to environmentally friendly, with the current low cost of funds, limit the development of WB.

Study of diversity of weed communities in wide row crops in Podkrkonoší Region
Kocour, David ; Kolářová, Michaela (advisor) ; Václav, Václav (referee)
The main aim of the master's thesis was an assessment of weed communities in Podkrkonosi Region (the area underneath the Giant Mountains) (Pokrkonosi). The effect of the crop (maize, potatoes) and altitude with a particular focus on thermophilic weed specieshas been investigated. The theoretical part outlines weed species referring to their significance, classification, harmfulness as well as benefits. The effect of climate changes, invasive plants, biodiversity and effect of temperature are discussed. Last part of the literary review is a brief description of model crops. In the practical part of the thesis, soil and climate conditions of the locality are described. Furthermore, a term phytocoenology is introduced and the methodology of recording relevés and the data conversion are explained. Totally, 99 weed species out of 25 families were found (69 in maize, 85 in potatoes). Chenopodium album agg., Echinochloa crus-galli and Fallopia convolvulus were the most frequent species in maize. The species with the highest cover were Fallopia convolvulus, Chenopodium album agg. and Echinochloa crus-galli. Chenopodium album agg., Echinochloa crus-galli and Viola arvensis were the most frequent in potatoes. Chenopodium album agg., Fallopia convolvulus, Echinochloa crus-galli and Galinsoga quadriradiata can be classified as the weeds with the highest cover. Euphorbia helioscopia and Sonchus arvensis were positively correlated with increasing altitude, while Amaranthus retroflexus, Solanum nigrum and Galinsoga quadriradiata were negatively correlated. Thlaspi arvense and Echinochloa crus-galli were characteristic species in maize, and Veronica persica, Galinsoga quadriradiata and Sonchus arvensis in potatoes. It can be concluded that potatoes fields showed higher species richness than maize, especially in higher altitudes. Maize was characterized by narrow weed spectrum with few predominating species. The tested hypothesis was confirmed and a statistically significant effect of altitude on the occurrence of thermophilic weed species has been found.

Analysis of financial results of Czech companies and their relation to the macroeconomic development
Kuna, Petr ; Marek, Petr (advisor) ; Dufková, Eva (referee)
The foundation stone of this thesis is to perform a financial analysis of Czech non-financial companies for the years from 2007 to 2009 in order to evaluate development of the basic groups of financial analysis ratios before and after the outbreak of the financial crisis. Based on this analysis, I analyze the changes of the selected ratios in relation with the macroeconomic development. This is carried out by means of the description in words and for some significant changes using correlation analysis with GDP. The analysis results in the findings that the changes of ratios of return on assets and return on equity were negative in the analyzed period and for each year the factors of these changes are tracked using the pyramidal decomposition. In the statistical part of my thesis I partially succeeded in proving linear correlation between return on assets and GDP and a lower confidence level linear correlation between personnel cost to revenues ratio and GDP. Also, there were some correlations between individual ratios found to be significant.

Economic analysis of labour market disrimination
Brčák, Ondřej ; Brožová, Dagmar (advisor) ; Chytilová, Helena (referee)
The aim of this academic paper is to analyse the possible presence of discrimination against women in the job market. The analysis attempts to endogenous the discrimation section within the model. That is the essential difference in regard to other papers on this topic as these ascribe the influence of discrimination to the unexplained gender wage gap. The basic thought of this model is the idea, that if dicrimination against women is present in the job market, then it must exhibit the signs of a normal good. An examined characterisitc is the correlation of the wage gap, taken as a good, and extra variables as pensions. Investigation of possible correlation is done according to the linear regression analysis. The regression results are not satisfactory over long time periods as there are many variables that affect the outcome that the model does not consider. More precise results were achieved by means of testing individual workplaces, where especially the regression conducted with available data from analytic management occupations suggests that discrimination against women may be present

Political and Rabindranath Tagore
Wolf, Jakub ; Hrubec, Marek (advisor) ; Petříček, Miroslav (referee)
The thesis deals with actuality of the texts by Rabindranath Tagore in relation to the concept of the political as presented by Michel Foucault. It identifies formative rules of the discourse presented by the referred texts and at the same time it reveals relation of Foucault's Archaeology of Knowledge to the immaterial and it presents the possibilities of ethics in relation to this concept due to correlation of the Archaeology of Knowledge and Tagore's concept of the ethics of withdrawal. The thesis' basic instrument is identification of the centripetal and centrifugal forces and actualization of their relations as fundamental rules of the formation of Tagore's text by means of constituting system formations connotated by its discoursive formations.

Structural-Functional Correlations of Hydroxymethylbilane synthase
Douděrová, Dana
Acute intermittent porphyria (AIP) is an autosomal dominantly inherited disorder, classified as acute hepatic porphyria. It is characterized by a deficiency of hydroxymethylbilane synthase (HMBS, EC 4.3.1.8), the third enzyme in heme biosynthesis. Clinical features include gastrointestinal, neurologic and cardiovascular symptoms, but the most common clinical presentation is abdominal pain caused by neurovisceral crises. The purpose of this study was first to perform molecular analysis of the AIP patients. Once a mutation is detected in a patient, molecular testing is offered to family members. In each affected family, this becomes an important tool for individualised medicine, allowing for careful drug prescription; in addition, it is very important for the asymptomatic carriers to be warned of precipitating factors, thus avoiding an acute attack. The proper DNA diagnostics can be achieved by a combination of a robust and effective pre-screening method and a confirmatory DNA sequencing step. We decided to establish a new generation pre-screening method, which will be highly sensitive and relatively time- and cost-effective. Our method of choice was high-resolution melting (HRM) analysis using the LightScanner instrument. Another important aspect of this project was to study the molecular...

Optimization of the Determination of Septonex in Pharmaceutical Preparations by Capillary Zone Electrophoresis with Use of Organic Solvents as Additives in the Background Electrolyte
Šindelková, Martina ; Pospíšilová, Marie (referee) ; Polášek, Miroslav (advisor)
OPTIMIZATION OF THE DETERMINATION OF SEPTONEX IN PHARMACEUTICAL PREPARATIONS BY CAPILLARY ZONE ELECTROPHORESIS WITH USE OF ORGANIC SOLVENTS AS ADDITIVES IN THE BACKGROUND ELECTROLYTE A new method of capillary zone electrophoresis with contactless conductivity detection for the determination of septonex in pharmaceutical preparations was devised. Optimal conditions for the separation and determination of septonex were: background electrolyte 30mM MES of pH 7.0 (adjusted with 200mM TRIS) containing 12.5mg/ml of (2- hydroxypropyl)-β-cyclodextrin and 20% (volume), voltage 25kV, temperature 25řC and sample injection for 6 seconds under the pressure of 50mbar. Arginin (200µg/ml) was used as internal standard. The peak of septonex was satisfactorily separated from the peak of internal standard as well as from the EOF. The analysis was carried out in a fused-silica capillary (internal diameter 50μm, total length 75cm and the length to the detector 45cm). The separation took less than 5 minutes and the overall analysis time involving appropriate rinsing of the capillary was less than 13 minutes. The calibration curve was linear in the range 75µg/ml - 400µg/ml of septonex, correlation coefficient r = 0.9997. The LOD was 13,5μg/ml and LOQ was 45μg/ml of septonex. The method is applicable for qualitative as...
