The master thesis is focused on the bound sulfur dioxide, especially on its first dosage into the wine after the alcohol fermentation. The first part describes the properties of sulfur dioxide, its effects, bounds and dosing. Next it includes the theoretical background of sur-lie wine aging process in conjuction with the sulfur dioxide. The second part of the thesis was an experiment with the sulfur dioxide dosing into the wines right after the alcohol fermentation in comparison with sur-lie aged wines. The free sulfur dioxide was examined in the resulting wines. It was found out that sur-lie aged wines have a positive effect on redox potential and therefore on keeping higher free sulfur dioxide amounts which results in lower sulfiting dosages needed.

The main aim of the diploma thesis "Quality of fine pastry influenced by fiber" was to design a recipe containing 2%, 4% and 6% of bamboo pulp, wheat fiber and apple fiber. Further, the aim was to assess the effect of fiber addition on the quality of fine pastry. In the practical part, bakery experiment, sensory analysis, universal tension / pressure test, nutritional value and color of surface and surface were determined by spectrophotometric measurement. The results were processed in Statistica 12 and MS Excel. Ten samples were baked. Maximum weight after baking was sample no. 4, with the addition of 6% bamboo fiber BAF 200. The lowest values of density of the samples reached with addition of 3% bamboo fiber was most favorable overall sample containing 4% bamboo fiber BAF 200. The highest strength was measured for the sample 5, to which 2% bamboo fiber BAF 400 was added. The lowest energy value had sample 4, ie with the addition of 6% bamboo fiber BAF 200.

Final thesis deals with research of exploitation of "sur lie" method in production of white wine. The focus is given on stability of wine, especially, stability against crystallization of tartrate salt acid in bottle, proteins stability and antioxidative nature of fine lees. First part of the thesis describes process of wine production by method of aging on fine lees. Composition of lees and cells of Sacharomyces cerevisiae together with its risks and benefits are illustrated in theoretical part. Experimental work monitored development of the wine stability in micro samples. The wine used for research purposes was variety of Silvánske zelené. Antioxidative capacity was monitored by FRAP method in the time of 16 weeks. Stability of proteins was measured by heat protein test and by turbidity meter. Content of tartrate salt was measured by filtration of samples and then weigh on laboratory scales. Sensory analysis was made by blind wine tasting degustation of professional commission. The results confirm higher protein stability which is about 30% more than in control sample. Risk of tartrate salt crystallization was reduced about 80 % in comparison with initial state. Antioxidative capacity of wine demonstrates slight decrease, but real required dose of SO2 added into wine was reduced. Key words: sur lie, bâtonnage, tartrate salt stabilty, antioxidative capacity, fine lees, mannoproteins, yeast cell, protein stability

This work deals kinetics of grinding Portland cement clinker which is influenced by addition of grinding inlays surfactants. In an experiment, attritor-type stirred mill was used and surface active grinding additives such as polyethylenglykol (PEG), triethylamin (TEA) and acetate of ammonium were utilized. Granulometric distribution graph obtained from laser diffraction analysis provides data for plotting development diagrams for milling process.

The focus of this master’s thesis is the issue of fine dust particles suspended in the air and their measurement. The thesis explains the basic characteristics of fine particles and the rules, which they follow. The section then examines the health risks of inhaled particles. Next is explained the influence of particles in the air on the environment, the historical development of the air pollution in the Czech Republic and the most important pollutants. After that is described the legislation, which frames the limits for pollutants suspended in the air. In the practical part is described the methods for calculation the geometry of cascade impactor, the design of three-stage impactor and finally the comparison with professional impactor. The designed impactor was then constructed and tested with wood burning stove as a source of particles.

This diploma thesis is devoted to the issues of the formation of fine particles in dependents on the combustion parameters. The first part of thesis is review, which summarized the information about combustion process and about formation of the gaseous products and fine particles inside them which created during combustion process. The main content of thesis is realization of measurements of fine particles from combustion, in several types of the tested combustion devices. Next part is a description of used measurement devices, which used for measurement. Last chapters are focused on evaluation of results from the measurements, comparison of the measurements between themselves and the finding the existence of the dependence of the formation of fine particles on operational parameters of boiler. And all results are evaluated in the conclusion.

This diploma thesis deals with issues of fine and ultrafine particles formation during thermal decomposition and combustion of biomass. An introduction is devoted to a utilization of biomass as fuel. A following part describes the gas products emerging generally during combustion process. A current emission and air pollution situation in the Czech Republic as well as the health impacts of solid pollutants on human are also mentioned. Within an experimental measurement three basic factors that have impact on fine particles formation during combustion of beech wood (i. e. oxygen content in combustion atmosphere, type of the sample and size of the sample) were thoroughly analyzed. Attention was paid to a progress of thermal decomposition and combustion of sample with respect to the particles formation. Finally, a measurement of fine particles amount was accomplished in a real boiler successively with four different biomass pellet types.

The diploma thesis is divided into three parts, analysis of the topic and the chosen method of solutions, application to specified building and experimental solutions and data processing The first part is theoretical. It is about air filtration in terms of normative and legal requirements and variants of technical solutions for air filtration. In the second part there are two technical solutions for HVAC systems for plastic surgery. The third part is experimental. It is the measurement of the number of particles in the air in the operating room and the evaluation of the measurement.

This thesis is focused on nanoparticles produced by internal combustion engines utilized in vehicles. It deals with spatial distribution of nanoparticles within urban areas, impact of alternative fuels usage on particle production and toxicity, and a particle toxicological testing methodology. Monitoring of airborne nanoparticles identified traffic as the main source of airborne nanoparticles in places with heavy traffic load (Prague), as well as in a small city with only local traffic (Čelákovice). Most particles were likely emitted during short episodes of high emissions (e.g. uphill acceleration). During the measurements, high-emission vehicles responsible for a large fraction of the air pollution were also identified. On the other hand, small non-road internal combustion engines, which are not subject to any limit on particle emissions, such as a lawn mower, were operated during the measurement and generated a large number of nanoparticles. The amount and characteristics of the particles produced by combustion depend on the combustion technology and the fuel composition. A large part of the thesis deals with alternative fuels and their effects on the quantity of produced particles and toxicity of organic matter adsorbed on the particles. Hydrotreated vegetable oil (HVO) exhibited the lowest...
