This thesis investigates the influence of weather conditions on the properties of the film.There was selected six kinds of tree species, which are used for the manufacturing of the outdoor furniture the most. There was a request for possibility to grow this kinds of trees in the Czech Republic. There was used five shades of color on the each tree species. Samples were tested at the laboratory before putting to the exposure and when the summer season was over, samples were tested as before. In discussion there is statistical comparison of changes which occurred on the surfaces of the samples. In the end of the diploma thesis is evaluation which are the best tree species and the best color shades for the manufacturing of the garden furniture.

The aim of this thesis was to compare the wheat flour quality of Czech and foreign producers. Soft wheat flour was evaluated from 14 producers from the Czech Republic and 21 foreign producers (from Austria, Slovakia, Romania, Ukraine, Australia and New Zealand). The basic technological analysis of these flour samples was made and farinograph properties of doughs were carried out on farinograph device. The baking experiment with the quality parameters evaluation and sensory analysis of baked products were made, the flour and crust colour was determined and the baked products compactness was carried out as well. The Czech flour quality didn´t differ from foreign flour significantly (level of importance = 0,05). Only Zeleny sedimentation test and drop dough consistency were different, where the Czech flour was evaluated better.

Internal and external factors affect the quality of meat, however ageing affects final product. Main objective of this work was to determine the effects of ageing on selected physical factors (pH, colour, water holding capacity and texture shear force) which affect meat quality from consumer and further meat processing perspective. Measuring of those factors was performed in periodical time sequences (one day post-mortem and 14 days of ageing) and factors of raw and heat-modified meat were measured. There were two hundred and fifty-eight samples from Czech pied cattle used in research. Musculus longissimus lumborum et thoracis (sirloin) was analyzed. Statistically high shear force difference (P=0.001) was identified at heat-modified and aged samples (decrease from 22.574 kg to 14.885 kg). Decrease of shear force during ageing of raw meat samples was observed at normal pH (pH < 5.8) beef ? from 6.403 kg to 5.982 kg. Correlations between pH and water holding capacity was found at samples which undergone ageing (r = 0.879 ***) and also at one day post-mortem samples (r = 0.872 ***). Middle correlation was observed between colour and pH at all colour parameters ? L* (r = -0.479 ***), a* (r = -0.478 ***) and b* (r = -0.581 ***). Water holding capacity and pH have influence on shear force of raw beef and also heat-modified beef; this was confirmed by correlation analysis. Lightness (L*) and water holding capacity affect heat-modified samples texture which was confirmed with multi-regression linear analysis (R2 = 0.565). As shown above the influence of meat ageing on quality parameters is high and properly aged meat from young bulls has better texture values. If the aged beef will be sold regularly it could be expected that consumer demand will increase especially due to remove the inconsistency of the quality of beef.

The theoretical part includes sections on various theories light and colors concepts in relation to the historical context. It also deals with topics that are directly related to light, such as shading, lighting, etc., and their symptoms in art, painting, glass, mosaic and glass windows. The practical part is trying to capitalize on the knowledge gained in the file author's books as light objects. For those is attention focused mainly on specific features of various materials and their effect on humans in conjunction with the light.

This theses focused on the topic of silence and sound is divided in two section. Theoretical part contains information and knowledge from fields of physical phenomena, theory opf colors, psychology and theory of art (mainly based on work of W. Kandinski), that establish theorethical baseline for practical part, in this case realized graphic intent. Realization of practical part is an authorial construction of plastic interpretation of silence and sound. It tries to graphically express these two constructs with combination of pottery and glass in colorful compositions.

The aim of this thesis is to suggest a methodics for using colors in marketing and this methodics demonstrate in practice on the specific products of graphic design. To obtain information is used questionnaire investigation. For further determine behaviour of people, their opinions and attitudes is with the part of the respon-dents completed the questionnaire personally with the space for discussion. The results are statistically and graphically analyzed. The attention of the work itself is devoted to the presentation of the marketing research results and to the proposals of methodics for using colors. This methodics is applied to specific products of graphic design.

The investigated subject for this diploma thesis is getting know properties of the vanadium redox battery (VRB), especially electrolyte. Specialization is applied to the state of charge of this cell and its measurements using the optical methods. Upon different state of charge is changed oxidation number of vanadium and resultant color of the electrolyte. Using spectrofotometry method that characteristic property is undergone measurement. The basic thing was learning to handle a measurement system. The first practical measurement was executed on example foils. Upon measurement of vanadium cell there was obtained the values of absorbation, which they were used for determination of state of charge.

The object of this thesis is to focus on the major influences of vehicle saleability in Czech Republic in terms of the most important criteria, such as price, fuel consumption, colour etc. Part of the work will be arranged questionnaires. The survey indicates desirability of cars back for the last five years. This creates sales trend with a hint of future development.

This thesis describes summarizing and comparsion of advanced dithering techniques used to reduce the image color space on n-dimensional palette. The goal is to create a set of basic methods including theirs enhancements and modifications focusing on the output image quality and maximum visual fidelity to the original image. Another part of this thesis is to analyze this methods using own comparsing method and design new dithering algorithm combining their advantages.

A feed test was carried out on male “Vistar” rats. Four groups of rats, feed with mixtures with 70 % of wheat, differing in grain colour, were compared. For feed trials, near-isogenic lines of derived or recipient varieties of “Novosibirskaya 67” (N67) were selected. These were the N67 grains with white grains, “ANK-28A” with purple grains (Pp1 and Pp2 genes), “ANK-28B” (Pp1 and Pp3) and “Aoi Yu” (unfinished near-isogenic line) with blue aleurone (Ba1 gene). Feed mixtures were standardized to the same nutrient content. The feed trial lasted 72 days. Time increments and biochemical parameters of the blood were evaluated. Statistical differences in glucose (GLU), triglycerol (TG) and total protein (CB) levels were noted in biochemical parameters, with a higher GLU content in N67 and “Aoi Yu”. Higher TG content was recorded in “ANK-28B” and lower in “ANK-28A”. The higher CB content in rat blood was recorded in “Aoi Yu” and lower for all remaining wheat. No statistically significant differences were found in other biochemical parameters of blood (P<0.05). Interestingly, a higher feed consumption per pound was observed in the wheat mix with white grain (N67) and the lowest in “Aoi Yu” with the highest content of anthocyanins. This result is in line with the results of some other authors who have shown a relation between the high anthocyanin content in the feed and the reduced weight additions of laboratory animals.
