Procedures of the use and application of the biochemical preparations to the aquatic environment quality and water elements sediment state adjustment in the frame of cultural heritage management
Rozkošný, Miloš ; Hudcová, Hana ; Kratina, Josef ; Sedláček, Pavel ; Dzuráková, Miriam
The monument procedure contains knowledge and instructions, which, according to the experience gained, should contribute to solving the unsatisfactory state of the aquatic environment in terms of water quality, excessive algae growth, increased turbidity, odor, and worsening conditions for fish life. This is usually associated with fluctuations in oxygen content and pH of water, the occurrence of toxic forms of metals, ammonia, etc. One of the parts is devoted to the possibility of the application of biological and biochemical preparations to reduce the organic component of sediments and reduce their volume. Recommendations are given for the survey of sediments, analysis of their composition, and determination of a suitable procedure for the application of preparations. Part of the monument procedure is documentation for the design and production of cultivation equipment for biological preparations (bioreactor), including description of its operation and maintenance.

Sustainability principles of fish stock of cultural monuments and historical settlements water elements
Adámek, Zdeněk ; Rozkošný, Miloš ; Hudcová, Hana ; Kratina, Josef ; Sedláček, Pavel
The object of the monuments procedure is to put into practice suitable and verified principles of composition of fish stocks of cultural monuments water elements, for production ponds and reservoirs, and for ornamental reservoirs, basins and pools. At the same time, it brings information about methods of fish stock management, principles of introduction of predatory fish, use of fish for biomelioration of aquatic environment. It also provides recommendations for the maintenance and care of farmed fish. To achieve this, it also includes a section aimed at identifying and describing an appropriate approach to solutions to improve water status, including water quality, and ensure the sustainability of fish stocks. Part of the monuments procedure is also a brief analysis of the issue of degradation of the reservoirs and ponds environment from the perspective of fish survival, due to pollution and water eutrophication. It also describes the individual causes of the unsuitable state of the aquatic environment.

Possibility of using VIS - NIR spectroscopy for predicting the properties of forest soils
Kratina, Josef ; Borůvka, Luboš (advisor) ; Lucie, Lucie (referee)
The aim of this PhD thesis was an objective assessment of application of VNIR spectroscopy for predicting properties of forest soils. For each soil property were found the most appropriate combination of statistical methods for pre-processing (continuum removal, 1. derivation, 2. derivation) and processing (PLSR, PCR, SVM) of certain spectral bands. As generally successful shows a combination of methods 1. derivation and support vector machine throughout the VNIR spectral range (400-2500 nm). In some cases, however, they proved to other models. Among the best predictable features include pH, content of oxidizable carbon, aluminum, iron, silicon, or calcium (at higher concentrations). Not very high success rate prediction was found in indicators that take low values (sodium, manganese, aluminum or ferrous complexes). The results show that VNIR spectroscopy method is applicable for predicting properties of forest soils. It can not completely replace traditional analysis, but it can very well complement, especially in practice. For example, when the soil mapping can help thicken network data and refine the information better than other methods of spatial estimation. It is applicable in cases where it is required large amounts of data in a short timeframe and at minimal cost. It is suitable for monitoring trends over time, or for a quick survey of an area.
