The primary goal of this master thesis was to analyze the development of ownership of daily newspapers in the Czech Republic in the period 2008 - 2016. The development of media ownership in the monitored period was analyzed in the context of the long term structural problems of media sector, which were intensified by the economic crisis beginning in 2008. In addition to the economic context, the thesis also deals with the historical context, specifically the changes of the Czech daily newspapers market after 1989. In connection with the transfer of ownership of the Czech publishing houses to the hands of domestic businessmen, often with direct links to politics, thesis also deals with the issue of ownership concentration and the relations between media and politics. I also mention the phenomenon of emerging new, alternative media projects by the journalists in reaction to ownership changes threatening pluralism and freedom of speech. In the end, I also compare the development of ownership of the daily newspapers in the Czech Republic with the development of ownership in other countries of the CEE region, such as Slovakia, Poland, Hungary or the Baltic States.

The diploma thesis "The media landscape in Spain" aims to describe the contemporary Spanish media scene and apply the basic characteristics and particularities of the "polarized pluralist model" media system which was described by Hallin and Mancini in their book Comparing Media Systems and whose features are also allocated to other South European countries (Italy, Portugal, Greece and marginally also France) in addition to Spain. The description of the press and audiovisual media market itself is preceded by three extensive chapters dealing with press media development in Spain from its beginnings in the 17th century until today, media legislation and the concentration of media ownership. It was the development of the press (and, in the 20th century, the development of audiovisual media) which, due to its exceptionally close ties to politics, determined the shape of the contemporary Spanish media landscape, which is why the thesis focuses primarily on this topic. The historical and political development of the country and constantly changing systems of government led to frequent changes in law (press laws in particular), which makes Spain very different from other European countries in this aspect. The chapters dealing with the press and audiovisual media market refer to the weak tradition of...

The dissertation is divided into three parts. The first part deals with the origin and characteristics of modern retail chains and instruments of analysis assess the competitive forces in the industry. The second part is devoted to the parameters of business conduct and analysis of the allocation of economic surplus in favor of the retailer. The third part is devoted to the role of prices in the retail, including price wars and its impact on suppliers and consumers

The thesis deals with the study of surface-active properties, zeta potential, particle size and adhesion of surfactants (Arkopal N110, Igepal CO-520, Igepal CO-890, Dehyton PL, sodium dodecyl sulfate and dodecyltrimethylammonium bromide) selected for full notch creep test method. To determine the surface phenomena occuring in a solution due to their presence at 25, 50 and 80 °C, the Du Noüy ring method of surface tension measurement was used. The importance of factors such as concentration, ionic character and the molecular structure of the surfactants, temperature and dispersion media (pH, purity) were analysed. Dynamic light scattering measurements were performed in order to evaluate the particle size and the electrophoresis method was used to determine the zeta potential. The results were compared to the contact angle measurements, i. e. adhesion tendency between surfactant solutions and the surface of selected types of high density polyethylene. The optical analysis was used to evaluate the contact angle. The negative impact of water purity was negated. The temperature dependecy was specific for each of the examined surfactant species, however the relationship between temperature and the length of hydrophilic chain was discovered. Alkaline pH was less convenient for amphoteric surfactant than acid or neutral environment, but this might have been caused by components contained in the buffer. The character of surfactant solutions was mostly monodisperse. The only exceptions were 1mM Igepal CO-520 and 3mM Dehyton PL. Further investigation led to conclusion that the molecules tend to form agglomerates. Adhesion was in accordance with surfactant effectiveness of surface reduction and adsorption. However, this theory did not match the data obtained from testing acid and neutral Dehyton PL solutions' adhering to polyethylene species containing carbon black.

This Master’s Thesis deals with the design of ventilation and cooling of an under roof flat in a tenement building, built in the 1980s, and consists of five main parts. Within the first main part, the thesis is dedicated to the research of the current state of knowledge in the area ofventilation and cooling of residential premises, secondly, there is a detailed description of a particular flat, thirdly, the calculation for the optimal design of ventilation and cooling are made and, in the fourth part, suggested solutions are proposed with the following evaluation of them including the overall summary. The design of ventilation and cooling was carried out according to the design procedures with respect to the relevant standards and optimized to achieve the desired effect with respect to the requirements of the owner of a housing unit. As a solution, the ventilation of a flat by the Jablotron Futura´s ventilating unit and three variants of a flat cooling were proposed. After the evaluation of all cooling variants, the Sinclair´s multisplit system of cooling was chosen as the most suitable one.

In this diploma thesis, the diurnal changes of initial and total Rubisco activity and Rubisco enzyme content in beech (Fagus sylvatica) were studied under conditions of ambient (A) CO2 concentration (350 µmol.mol-1) and elevated (E) CO2 concentration (700 µmol.mol-1) during the day. Samples were taken on July 8th (from 10:00 to 21:30), on July 9th (from 04:00 to 12:00) and then on July 22th (from 04:00 to 21:30). The initial and total activity were measured spectrophotometrically and the activation level was calculated from the ratio of initial and total activities. Rubisco enzyme content was determined by SDS-PAGE method and the initial and total specific activity were calculated from the ratio of initial or total activity and Rubisco enzyme content. In our experiment no statistically significant difference was found between Rubisco activities in beeches cultivated under conditions of ambient CO2 concentration and elevated CO2 concentration, so any down-regulation of Rubisco activity did not appear under the influence of ambient CO2 concentration. Diurnal changes of Rubisco activities showed only statistically nonsignificant fluctuation. After daylight no significant increase of total Rubisco activity was observed, which demonstrates the absence or the immaterial effect of CA1P night inhibitor in beech. Intensive fluctuation of the activation level (40–90 %) proves the regulation of photosynthesis during the day via Rubisco enzyme carbamylation. Rubisco enzyme content in beech cultivated under conditions of ambient CO2 concentration was lower than that one in beech cultivated under conditions of elevated CO2 concentration. Then down-regulation of Rubisco enzyme content is presented under conditions of ambient CO2 concentration. Before daylight Rubisco enzyme content showed an indistinctive minimum on the level of statistical significance, during the day only nonrelevant fluctuation was noticed.

This diploma thesis deals with dynamic of accumulation of non-structural carbohydrates and activity of Rubisco enzyme at elevated concentration of CO2 on beech (Fagus sylvatica L.). Three years old seedlings of beech were cultivated in minisphere with ambient (385 µmol•mol-1, variant A), and with elevated concentration CO2 (700 µmol•mol-1, variant E) for four months. In every variant the first half of plants was fertilized by nitrogen (variant N+) and the second half was control (variant N-). Plants used for experiment were at first adapted for darkness for 12 hours. Subsequently tested leaves were cut off, leafstalk including short segment of branch (approximately 1 cm) was inserted into 0.7 M solution of sucrose (variant S) or water (variant V) and exposed to radiation 200 mol•m-2•s-1 for 0, 30, 60, 120, 180 minutes. Then leaf area and fresh mass of leaf blade were established, samples were fixed in liquid nitrogen and stored in deep freezer to analysis in –70 °C. Rubisco content was determined by SDS-PAGE method, Rubisco activity spectrofotometrically and content of non-structural carbohydrates by anthrone method and HPLC method. Rubisco content was significantly lower in the N- variant than in N+ variant. Rubisco content was also significantly lower in E than in A variant, which is an evidence of down-regulation. Rubisco activity is moderately stimulated at E variant with time, but differences between variant A and E are not statistically significant. Influence of sucrose feeding to Rubisco activity was not proved. Significant differences were detected by anthrone method in non-structural carbohydrates content between variants S and V, but not between variants A and E. Statistically significant increase of sucrose content with time was detected by HPLC method at variant AS, but not at variant ES.
