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.

Aspects of the disposal and recykling of photovoltaic panels in CR
Papírek, Jan ; Mikšík, František (referee) ; Kotlík, Josef (advisor)
This diploma thesis is focused on the assessment of the possibilities of disposal of photovoltaic panels installed in the Czech Republic. In addition to the basic theory of photovoltaic cells and panels, the theoretical parts describe legislation, subsidies in the field of photovoltaics and the development of photovoltaics in the Czech Republic. As part of recycling, their methods, work with the collective system, as well as the impact on the environment are analyzed. In the experimental part, using the data of the installed capacity and the average weights of the panels, various projections of the disposal of the panels over time are made, which take into account factors such as the life of the power plant or the capacity of the recycling line. Furthermore, according to the available literature, an analysis of the revenue from the sale of recycled materials contained in panels installed in our territory is performed. Subsequently, the needs of future implementers of proven estimates of labor and logical demands were assessed. Finally, an economic evaluation of the fundamental aspects of the FRELP recycling process was performed and the net prices of different recycling directions were determined.

Disposal of Biotic Pests by EMW Radiation
Sobotka, Jindřich ; Klečka,, Tomáš (referee) ; Myslín, Jiří (referee) ; Tomíček,, Oldřich (referee) ; Šuhajda, Karel (advisor)
The possibility of using high-frequency electromagnetic radiation in the construction sector is a common knowledge. Various experiments have been carried out to dry construction materials, or even to destroy biotic pests. However, the majority of these experiments have been executed in laboratory conditions. It means they have been carried out under exact limiting conditions, often very far off those conditions in real building practice. Therefore, this dissertation aims at exploring the possibility of utilizing microwave technology in drying and heating of construction materials, in disposing of biotic pests and sterilizing building materials under real conditions in building practice. The thesis will explain that microwaves are a term given to a part of electromagnetic radiation. Electromagnetic radiation is based on the principle that the radiated energy is absorbed by water molecules present in moist building material. In the mass of the irradiated material, the radiated energy is transformed into thermal energy, where a so-called “motion” of water molecules occurs with the energy then being transformed into kinetic energy. The microwave technology itself offers a very wide range of use, which can be easily achieved, thus making the technology available to use in the future. Part of the experiments and the necessary measurements, too, has been carried out on selected types of building materials in the premises of the Faculty of Civil Engineering of Brno University of Technology. They have been executed under conditions which most closely correspond to the conditions in real buildings. Part of the experiments and the necessary measurements were carried out on particular constructions, by the so-called in situ method. As stated in the conclusion of the dissertation, laboratory measurements and the in situ measurements differ considerably in some cases.

Life cycle of wooden structures
Pavlíková, Šárka ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
This thesis deals with comparing the costs of construction of the timber and classical walling system throughout their life cycle. The first part introduces the history of timber, wood as a building material, processing of wood for building purposes, construction of wooden buildings, durability, removal and recycling of wooden buildings. The second part evaluates the cost of building a family house from both types of material and also cost of living in both buildings since their creation until their licvidation.

Voluntary Liquidation of a Limited Liability Company from Accounting and Tax Perspective
Rymeš, Václav ; Kašpar, Jan (referee) ; Brychta, Karel (advisor)
The bachelor thesis is focused on the dissolution of a business corporation without a legal successor through liquidation with a focus on a limited liability company. The theoretical part defines the basic concepts and the course of the liquidation process. The analytical part deals with the evaluation of legislation and the progress of the liquidation process. Proposals of the thesis part consists in the creation of a framework liquidation procedure and the subsequent application of the procedure on a model example.

Economic Impacts of Winding Up a Company with Liquidation
Švandová, Kateřina ; Kramolišová, Eva (referee) ; Pernica, Martin (advisor)
The thesis deals with legislative aspects of the abolition of corporate insolvency and dealing with the expression of the economic consequences arising from the demise of the organization to key stakeholders (employees, state, creditors). The theoretical part deals with basic concepts related to corporate, legal forms of business characteristics, causes and forms of dissolution and its subsequent liquidation process. The practical part focuses on the company, joint stock company, which is in liquidation and the economic consequences arising from the termination of the business activities of this company for state employees and creditors of the organization.
