The thesis is focused on variable cabinet system , more specifically, the formation of storage furniture that is possible with the switching system to associate with each other to get the whole and storage furniture according to preference . Proposal storage furniture was conducted in cooperation with Dřevotvar team. In the first part of my thesis focuses on human habits and needs that should be taken into account when creating furniture. Also looks at the historical development of storage, when I made a brief cross-section of a gradual shift from primary storage furniture chests across the major milestones that influenced the look and function of storage space, to design furniture today. Then I summed up the storage requirements, ergonomics, anthropometry, hygiene, safety and technical regulations. The very design is based on the knowledge gained from entering a cooperating team Dřevotvar research and competitive products. The data is then used for making your own design with possible variants. The resulting design is assessed by means of an anonymous questionnaire and evaluation of the data obtained with regard to price and interest in the product .

Abstract Introduced tree species are still undoubtedly, despite the current short-term politico-economic and environmental turbulences, an object of interest of the Czech forestry sector. Worldwide the most important tree species, and thus both in the areas of its original extension and in the large regions where it was successfully introduced, is the Douglas fir (Pseudotsuga menziesii), which is considered as one of the most perspective tree species. Information about the quality of its wood from our territory is missing for the time being. That´s why the aim of this work was to evaluate the quality of Douglas fir wood from different regions of the Czech Republic through selected mechanical properties. Especially the compressive strength, impact strength, flexural modulus and flexural strength were determined by standardized procedures. As well as, the variability of the trunk features and that one of the locality were taken in consideration. The final results of the mechanical features compared with the values measured on the wood from the original extension areas are better in compression strength, similar in flexural strength and slightly worse in the flexural modulus. Comparing the resultant values of Douglas fir with the values of domestic spruce, the Douglas fir shows better values, apart from the values of flexural modulus, which are higher in case of the spruce. A statistically significant difference between the location and the measured feature is demonstrated only in the elastic modulus and density. At the variability in frame of the trunk there was found a statistically significant difference between the vertical and horizontal position of the trunk and all the measured features. At the same time, the value of the measured feature increases together with increasing position from the pulp.

This diploma thesis was created to evaluate of selected physical properties, density and shrinkage of Douglas-fir (Pseudotsuga menziesii / Mirbel / FRANCO) wood, coming from areas of Lesy města Písku, s.r.o. and the territory of School Forest Enterprise in Kostelec nad Černými lesy of Czech University of Life Sciences. The work tested density and shrinkage, their subsequent comparison with native species and the relevant data from the regions of original distribution of these species. It was also assessed if these physical properties are affected by location of growth or if they vary between individual trees and what is the effect of horizontal or vertical position in a stem on the tested values. It was shown that the density reaches higher values than our native trees. It was found that location of growth or individual trees have influence on the tested properties. The value of density is decreasing with growing height of the tree and increasing with growing distance from the center of the tree. Shrinkage in tangential direction was lower in comparison with Scotch pine, but higher in radial direction. Volumetric shrinkage reached lower values than Scotch pine.

The aim of this diploma thesis was to verify the new capabilities for mapping variability of soil using measurement platforms mounted on machines for tillage. The chapter Soil describes types of soil in the Czech Republic, the causes of soil variability and the methods of spatial interpolation. The chapter Mapping Spatial Variability of Land focuses on the method of determining the variability of soil properties through direct and indirect methods, selection of locations for collection of soil samples, methods of measuring electrical conductivity and an overview of options for mapping, mainly via on-the-go sensors. The last part of the literary research is entitled Geographic Information System where I have described the purpose and uses of this system in precise farming. The subsequent practical part of the diploma thesis focuses on evaluation of the level of variability of farm land based on measuring of soil conductivity via a galvanic contact method of measuring and its subsequent comparison during use of an EM 38 MK2 soil conductivity probe. The conclusion contains a summary of the thesis and evaluation of the level of agreement between the obtained data files.

Abstract: European beaver population in Central Europe originated from several refugial populations. Although these populations are currently well-researched, but the manifestations that may reflect genetic variability, are not known. In the Czech Republic there are beavers who spread from Saxony, from Magdeburg refugia, and other stocks that are created by beavers from Austria and Bavaria, or are the offspring of individuals coming from refuges in Poland, Russia, Norway and France. There are many indications that individuals from northern Bohemia (Elbe individuals of the population) have a considerable amount of differences. The aim of this study was to determine the exact age of mortalities beaver from the collection of the Department of Ecology FES. The most accurate estimate of the age is the closing of the basal opening of the tooth root and the sum of cement layers molars, but this method is time-consuming and technically challenging and therefore the work of trying to find another reliable criterion to determine the age of mortalities in the form of intervals of specific characteristics for each age class (juvenil, subadult, adult). Using statistical analysis, I conclude that the most cranial size determination for individuals age the length dimension is LCB (condyobasal length of the skull) and LAZ (zygomatic width of the skull). The most appropriate metristic characteristic to estimate the age appeared weight.

This thesis deals with the study of soil variability and soil properties through direct and indirect methods. The aim of this work was to verify whether the combination of data, determined by direct and indirect mapping methods, will allow to identify the variability that will be used to more accurately differentiate the cultivation measures. Within the thesis, a model of bare soil variability assessment was also developed from the RS data defined by the arable land blocks from the LPIS through the Principal Component Analysis (PCA) and Coefficient of Variation (CV). The model was verified by two sets of atmospherically corrected data and the observed values were compared with the results of Agrochemical Soil Testing (AST). Conformity was particularly evident in blocks with an area with more than 100 hectares, where a larg number of samples / pixels was evaluated. In order to verify the using of the data combination of directly and indirectly mapping variability, two plots of 53 and 38 ha were analyzed. At both sites, soil sampling, soil electrical conductivity (ECa) was measured, and the Digital Terrain Model (DTM) data and the derived Topographic Wetness Index (TWI) were obtained for optimization purposes. In total, three types of sampling designs were created for each data source of indirect mapping methods using regression analysis, variability of indirect mapping data, and a combination of ASP results from previous designs and indirect methods data. A comparison of the sampling designs has shown, that the combination of direct and indirect methods refines the variability of soil properties. However, there is a link between the input data of direct and indirect mapping methods. It is also evident, that sampling designs based on indirect measurement data provides more accurate information about the variability of the observed soil properties.
