In recent decades, the ecological status of the freshwater crayfish has changed drastically from a sensitive indicator of an aquatic environment to a tolerant species that can survive in a wide range of unfavourable conditions. Despite all controversies on being or not being proper bioindicators, crayfish are a key species that plays a crucial role in the freshwater ecosystem. Regardless of whether certain crayfish possess a particular environmental sensitivity or not, all species can be used in biomonitoring investigations. The main objectives of the present thesis were development and implementation of system for continuous monitoring of water quality using crayfish as the bioindicator. Being less complex than vertebrates (e.g., fish), but being sufficiently complex compared to some other hard-shell freshwater invertebrates (e.g., mussels), crayfish present a useful biomonitoring object, which is easy to manipulate with, and which provides experimental data which is easy to obtain, analyse and interpret. The first part of this thesis is devoted to an evaluation of crayfish as suitable bioindicators. We showed that, when conducting the biomonitoring of metals in aquatic biota, crayfish have sufficient tissues for a bioaccumulation survey. For this purpose, we examined the gills, muscles and hepatopancreas. We confirmed that the hepatopancreas was the primary target for accumulation of most of the examined elements (i.e., cadmium, chromium, copper, nickel, zinc). For higher relevance, crayfish surveys were compared to fish samples collected from the same locations. The second part of this work particularly focused on water quality biomonitoring based on the evaluation of crayfish ethophysiological characteristics. We examined crayfish reactions to both chemical (i.e. chloramine, chlorides, nitrites) and natural odours (i.e., food, heterosexual conspecifics, predator, etc). This approach was shown to be simple yet at the same time, complex and efficient. Such monitoring technique is easily implemented and does not demand long, complicated analyses, since monitored parameters, locomotor and cardiac activity, are evaluated immediately in real time. However, one complication is related to the unpredictability of an animal's reactions. Because studied characteristics may often affect each other, they need to be carefully traced and interaction between measured characteristics needs to be eliminated. The usefulness of such biomonitoring is conditioned by a reliable combination of behaviour and physiology, which enables detection of complex animal responses to environmental changes. As reported in the third part, we submitted an application for a patent of the developed system, and described in the patent sensor will be protected as utility model. Moreover, other crustaceans with sufficient carapace size (e.g., shrimps, crabs, molluscs) can be successfully investigated using presented system. The only challenge is that living organism can clearly indicate disruption of ambient conditions, but cannot detect what it has caused. However, there are powerful analytical techniques now, developed exactly for accurate determination of various compounds. The heart rate is species- and conditions-specific, so it cannot be applied as unified measure for all crayfish species, while visual analysis of heartbeat primary curves can be useful for establishment of referent crayfish heart rate values at their different functional states. The final part of the thesis is devoted to this issue. In conclusion, the developed biomonitoring system was shown to be highly practical unit using noninvasive technique for investigation of crayfish reactions under model conditions, with the potential of further application at broader research and industrial arenas.

The thesis deals with rules for right reporting of revenues, which result from International accounting standard IAS 18 -- Revenue. There is briefly characterized the harmonization of financial reporting in the introduction. After that follows the development and the history of IFRS. The third part contains the analysis of the standard IAS 18 -- Revenue and standard IAS 11 -- Construction contracts, including three according interpretations. The final section is focused on the research of ten annual reports with a view to explain the observance of IFRS standards in pracitice.

Planned obsolescence is the term used to describe incentives of companies to make durable goods faster obsolete. The aim of the study is to make a big picture and real situation about planned obsolescence practising and consumer disposal behaviour. First part addresses the theoretical background and provides comprehensive overview through different aspects of the good's durability issue and planned obsolescence characteristics and influences. Second part in further reference to the information provided in theoretical part examines the situation of specific durable products - laptops. From survey's results on consumer attitudes towards durability of laptops and real case study on Apple Inc. and its reliance to planned obsolescence, recommendations to the more sustainable consumption of consumer electronics are presented.

The aim of the thesis called: Long-term sustainability of state debt financing and the impact on development activities of the Czech government, is to evaluate the long-term sustainability. To achieve this aim the analysis of the development of the Czech state debt and identification of factors working for the deepening of fiscal imbalance was conducted. The work also explores the relationship between state debt and state budget expenditures on development activities of the government. Spending on research, development and innovation were chosen to identify that relationship. On the basis of the analysis there are suggested possible changes in fiscal policy which could contribute to improving the current situation and rebalance.

This diploma thesis is about long-term rehabilitation planning of water distribution system. First part is about legislative demands on rehabilitation planning in Czech Republic and about methods used abroad to do long-term reahabilitation planning. Second part of thesis is about own created method based on TEA Water (application about condtition assessment of water supply infrastructure). This method is tested on fictional water network and on real water network of Babice nad Svitavou.

This master´s thesis deals with evaluation of an investment plan of technological company KOVOLIT a.s., that considers replacement of currently used handling equipment in it´s operations. Feasibility of the investment is evaluated by using chosen tools for evaluating of investment effectiveness in order to decide whether the investment is suitable for the company.

My thesis deals with the influence of reconstruction of the long-lasting elements on the market price of the property, specifically on the family house. For a case study, I chose reconstruction of the roof, and its load-bearing part, because the reconstruction of this long-lasting element can be found in most cases. A case study is solved in the form of valuation of house before and after reconstruction, and it is done by two methods: according to the decree,by the comparison method and market valuation and also comparative method.

The thesis deals with the high-temperature embrittlement of 14%Cr ODS ferritic steel in liquid lead environment. The 14%Cr ferritic ODS steel ODM401 manufactured by powder metallurgy technology was used as an experimental material. The effect of the long-term annealing, surface corrosion attack in the melt Pb and Pb-Bi on the microstructure and mechanical properties was described. The subsequent microstructural changes were evaluated by means of scanning electron microscopy and transmission electron microscopy The mechanical behaviour of the experimental material was proven by means of microhardness test, impact test and static tensile test. The fractographical evaluation of fracture surfaces were performed on all samples. The surface attack and outstanding microstructural ganges were found after the long-time exposition of the steel in Pb/Pb-Bi melts at temperature 550°C/1000h and 500°C/1000h respectively. The embrittlement of the steel after exposition in Pb/Pb-Bi melts was comparable to the embrittlement after high-temperature annealing of the steel at temperature 650°C/1000h.
