Mečíř, Václav ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The bachelor's thesis describes the design process of a small wood lathe. The proposal itself is preceded by acquaintance with the issues and technical possibilities of this time. This is related to market research and comparison of individual lathe variants, with respect to the required machine parameters. The subsequent design contains a calculation report in which the transmission system and the spindle design, on which the greatest emphasis is placed, are solved, as it is the most important part of the lathe. Based on the calculation report, a 3D model and drawing documentation is created in Inventor 2021.

Diagnostics of the construction and technical condition of the granary building
Velát, Matěj ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
The bachelor's thesis deals with the diagnostics of the historic granary building and the conceptual design of the reconstruction for further use. The thesis focuses on the history of similar buildings especially in the Czech lands and on the historical development of the building. The practical part of the thesis denies the course and results of the preliminary inspection of the structure and the failures found which are further addressed in more detail in terms of their nature. The presumed reason for the occurrence of failures the state of failures their influence on the construction and an outline of the risk analysis resulting from the failures are determined. Furthermore, a proposal for a methodology of detailed object diagnostics is based on the results of a preliminary inspection. According to the information about the object found during the diagnostics two ideological proposals for further possible use of the object are processed, including the necessary construction modifications.

Possibility of using EMW radiation for killing biotic pests
Gintar, Jan ; Klečka,, Tomáš (referee) ; Pěnčík, Jan (referee) ; Šuhajda, Karel (advisor)
The remediation of building elements and structures in terms of moisture and sterilization (inactivation) of biotic pests is dealt with quite often in construction practice and in the construction industry itself, and is thus a topical issue. The issue is dealt with by specialized companies that know the use of available technology on the market, or are themselves involved in the development and improvement of these devices. Several methods are known for the removal of moisture and sterilization of biotic pests, with sufficiently high-quality data on the technology used, the suitability of the equipment used, a more detailed description of the application of the methods themselves and the results themselves. The methods themselves, for removing moisture and eliminating (inactivating) biotic pests, must be chosen according to individual requirements, as some methods will be more appropriate (more effective) and some less suitable. For the practice itself, however, it is important that the methods are sufficiently effective and at the same time available to the wider public (their economic side). In my dissertation thesis I focus on the potential of EMW radiation utilization not only for liquidation of biotic pests (fungi, fungi, wood decaying insects), but also elimination or reduction of necessary conditions for survival or development of these biotic pests. Therefore, my work also focuses on the presence of moisture, because moisture is a common factor in the vast majority of problems associated with the occurrence of biotic pests. Due to its intensity, it is one of the less time-consuming method and therefore a more cost-effective (economically) method. The research I conducted at VUT FAST focused on the use of microwave radiation in the control of biotic pests, under conditions that are close to those on real constructions. The use of a microwave method to eliminate biotic pests and at the same time to remove moisture has proved to be advantageous.

Furniture, design, function and fine arts
Grocholová, Magdaléna ; Šmíd, Jan (advisor) ; Grendelová, Erika (referee)
My work analyses the matters of furnituring, from first ancient creations to present days. I focus on characteristic features of historical periodes their development among variously levelled societies. I also reffer about restauration and repairs, and I think about the use of antique furniture in our times. I also mention the modern flow of designers or the Feng Shui, a method of setting the furniture in the household. Part of my work is commited to the display of furniture in the graphic art from 16th to 19th century. Didactic par of my work is focused on Arts, as a subject taught at the first level of basic school. I also conceived my own draft of an Arts lesson. The goal of my work is to create a summary of general knowledge about the topic with focus on it's history as well as to provide an insight to the core of furnituring, given the aspect of graphic art. Key words: Furniture, historici styles, interior, design, wood, fine arts, Art Education

Anthracological and xylotomy analysis from prehistoric archaeological sites and its relationship to vegetation conditions
Prach, Martin ; Novák, Jan (advisor) ; Beneš, Jaromír (referee)
Xylotomy and anthracological analysis belong to fundamental paleoecological methods used mostly for reconstructing evolution of past wood vegetation. The point of this analysis is utilizing either charred or uncharred ancient wood material in the form of taxonomical determination of particular fragments, resulting in conclusions pointing towards reconstruction of species composition of past vegetation. In its first part, this work deals with brief introduction of the method, containing its short history, different methodological approaches and possible complications with final conclusions. The literature review part contains geographically sorted analysis of studies from continental Europe from Spain to Sweden, published mostly in english. Keywords: charcoal, wood, reconstruction of vegetation, archeology, anthracology

Fungi associated with decomposing wood in temperate forests
Štercová, Lucie ; Baldrian, Petr (advisor) ; Zikánová, Blanka (referee)
Wood decaying fungi are an essential part of all forest ecosystems. On their functioning depends a number of other organisms which use substances produced during decay of wood. Enzymes that degrade wood represent indispensable tool for fungi in converting structural compounds of wood to water and carbon dioxide. That makes them an essential part of the carbon cycle in nature. The dynamic of fungal communities on decaying wood is determined by a range of abiotic and biotic factors. The variability of microclimatic conditions, differences in the wood humidity and a gaseous mode are identifying stress factors which define the presence of species adapted to those conditions. An important factor, with which we can partially predict community composition, is the degree of decomposition of wood and the history of a species on the substrate. Another indicator, which may partly explain the composition of the community is a way of dying of a tree and a type of decaying substrate. Often, the development of a community follows from the primary colonizers, with high tolerance to unfavorable conditions, through the secondary colonizers, which have the ability to obtain the substrate over primary colonizers, but require more stable microclimatic conditions, to late colonizers, who are adapted to stress factors as...

Mortality of small animals on singletrails in Marianské údolí valley (Brno, Czech Republic)
Homolka, Miloslav ; Mikulka, O. ; Kamler, J. ; Drimaj, J. ; Plhal, R.
Singletrail areas became a part of tourist business all over the world. Cycling routes usually go through the natural environment, they are used especially in the summer and therefore are quite evident that small animals are killed on them. The submitted contribution indicates what effects have the traffic on the singletrail on small animals in the deciduous forest environment (Brno, Czech Republic). During singletrail traffic insects and small vertebrates were killed. The number of cadavers of individual species was relatively small on the trails (3800 individuals of insect and 51 of vertebrates one during 3 months on the 11 km of the route) and traffic most probably does not endanger the existence of any animal species at the local population level. Mostly the common species were perished on the trails, but individuals of specially protected and endangered species were also killed there (Calosoma sycophanta, Bombus spp., Anguis fragilis, Bufo bufo) so this fact should not be overlooked and underestimated. For ethical and educational reasons, the construction of new singletrail areas should be preceded by careful research of particular area in order to map the distribution of small animals and choose the route with regard to minimizing mortality, especially endangered species of fauna.
