High rise building AZ Tower - construction technological project
Hrubá, Denisa ; Valenta, Michal (referee) ; Biely, Boris (advisor)
This master´s thesis is dealing with selected part of the construction technology project of the high-rise building AZ Tower. The main content becomes the realization of supporting gross upper structure. It compiles in detail the most optimal proposal of technological processes, working machines, schedule, control and test plan, occupational safety, environment protection, construction site equipment and last but not least, the coordination of four tower cranes. Apart from the architectural and technically impressive draft of the Czech Republic tallest building it will be interesting to deal with progress of the whole construction. New technologies and elementary construction activities adapting to work at extreme altitudes will be used.

Povrchové úprava dřevěného obložení dřevostavby
Šindler, Miroslav
This diploma thesis shall address the surface treatment of wood paneling of log homes. Samples representing wooden paneling were painted and exposed at two different locations in different climate conditions. The first set of samples was exposed on the premises of the Mendel University in Brno and the other one in Berkhamsted in UK. The placement of individual samples sample took place on the premises of the university where we were provided with iron racks on which samples remained for two years. Over the years, the above-mentioned measurement was performed on the roughness, lightfastness and gloss of coating material using respective devices. Samples, which were exposed in the UK, were inserted into the pre-formed racks made of oak wood and they were measured at the start of their exposure and after the completion of the experiment. That experiment shall show the changes of aesthetic and physical and mechanical properties which can be observed in individual plank lining. In our work we deal primarily with the change of the color and roughness of thematerial. As we know that wood exposed to external weather conditions is stressed by various factors, biotic as well as abiotic factors, the structure and appearance under these conditions are changing over time. These changes are also affected by the exposure of a product or the place where the test set of samples is exposed. Consequently, we will discuss the changes in color and surface roughness before and after the exposure.

Porovnání klasických a současných povrchových úprav stavebně-truhlářských výrobků v exteriéru
Luňáček, Martin
This thesis compares the differences between the use of classical and contemporary treatment practices of woodwork surfaces in carpentry, focusing on wood products made of acacia, oak, and spruce. Ox blood and used automotive oil were used for classical surface treatment whereas water-soluable pigment paints were used for contemporary treatment practices; choices were based on various conditions, such as weather, wind, or cardinal directions. Changes of the surface conditions were monitored and form the basis of this thesis; experimental measurement of samples, which were exposed to exterior conditions for ten months, form the basis of research data. A set of samples which were kept under constant environmental conditions with no access to light were stored in a laboratory in order to provide a set of contrasting samples to samples exposed to exterior conditions.

Porovnání klonů odrůdy Tramín po stránce kvalitativní a kvantitativní
Hub, Pavel
The aim of this work was to evaluate the qualitative and quantitative parameters of the clones of the Tramín variety. The introduction describes the Tramín variety, its origin, distribution, mutations and clones, and also deals with habitat requirements, variety resistance, cultivating properties And climatic conditions in the area of the experimental vineyard. In the experiment, the facts about individual clone analyzes are described, with methodology, site description, On which grapes were harvested and evaluated. Given the results of the comparison of the individual clones from the same site, it would be advisable not to focus on just one clone, but at least three clones to support each other. Not only in production technology, but also in sensory properties where one clone supports the second or third clone in one clone. It will also be appropriate to focus on the dependence of micro climatic conditions, soil conditions, The main objective was to recommend the suitability of a combination of Tramín clones with different properties for the production of quality wine according to the obtained data. Based on the results I would suggest focusing on the cultivation of French clones, Clones 47 and 1077, which provide a spice and a clone 46-106, which gives the wines of floral tones, fruity and delicate aroma. As they complement each other very well both in terms of yields and in terms of quality and aroma of the produced wines.

Srovnání tenkovrstvých lazur, silnovrstvých lazur a krémových lazur pro dokončování venkovního nábytku
Vrabček, Tomáš
In this bachelor thesis is solved the application of suitable surface finish of outdoor furniture made from solid oak and larch. There are compared three kinds of solvent-born semi-transparent wood stain with various characteristics. There were used low-build semi-transparent stain, high-build semi-transparent stain and semi-transparent stain of cream consistency. Physical-mechanical properties of the surface are evaluated depending on weathering (humidity, sunlight, temperature). There are give comparison of changes by the world side and changes of unexposed samples that were saved in a box and packed in the black foil without access of air and sunlight. This thesis is supported by laboratory measurements during the exposure period which was 4 months.

Povrchová úprava výrobku ze dřeva trvale umístěných v exteriéru
Lesák, Josef
In this work there is solved appropriate use surface finishing on wood products which were made from larch and acacia and were placed in the outdoor environment. There are compared three kinds of varnishes, namely water-soluble, synthetic and oil varnishes. Emphasis is put on changes in their aesthetic and physical - mechanical properties, depending on weather conditions, such as humidity, sunlight and temperature fluctuation. Then there is compared the extent of these changes depending on the orientation to the cardinal points. The work is supported by laboratory measurements on test samples laboratory measurement that have been exposed to weather conditions for a period of ten months outdoors. As opposed to these exposed samples were created reference samples that were throughout wrapped in black foil without air access.
