Integration in higher-order finite element method in 3D
Kůs, Pavel
Integration of higher-order basis functions is an important issue, that is not as straightforward as it may seem. In traditional low-order FEM codes, the bulk of computational time is a solution of resulting system of linear equations. In the case of higher-order elements the situation is different. Especially in three dimensions the time of integration may represent significant part of the computation.

Orienteering club support system
Buk, Jindřich ; Vojíř, Stanislav (advisor) ; Sklenák, Vilém (referee)
Nowadays, an increasing number of processes and life situations is getting IT support. Often the use of the Internet aims to accelerate and simplify existing processes. In addition, there is a big area of social networking that can be complementary. This thesis deals with the possibilities of using web technologies to support the running of a club and its subsequent development. Indeed, the club has the potential to simplify and automate many processes which previously have been carried out by someone in person. It has also a potential to use social networks for its publicity and development. The aim is to first determine what areas of the clubs operations are the most appropriate to be supported by any information system. Another objective is to find out how other clubs already integrate any information systems. The final objective is to design and create a specific application. The first two objectives are addressed through a survey among the leaders of the biggest Czech clubs. Indeed in these clubs, the use of automation and simplification of existing processes could have a great potential. The proposal for a specific application is then based on the previous survey and the field experience of the author. While serving many existing processes in running the club, the proposed application adds many elements of social networking.

The use of biomass ash
Ochecová, Pavla ; Tlustoš, Pavel (advisor) ; Radim, Radim (referee)
One of the most frequently used sources of renewable energy is biomass, mainly wood biomass. Incineration is the most common technology utilizing the energy from biomass to produce heat. A byproduct of these technologies is ash, whose composition depends on the feedstock composition and the incineration technologies. Due to the high content of valuable nutrients in ash, one of the suitable option for ash utilization seems to be application into agricultural or forestry land. Therefore, it is necessary to test response of soils and plants and look for the most suitable combination of soil additive (biomass ash), and plants. Experimental part of PhD thesis was divided into the incubation experiment and the vegetation pot experiments. The incubation experiment: The efficiency of ash addition at two application rates was tested for nutrients enrichment in different soils within period of 56 days. The vegetation pot experiments: The two plants Triticum aestivum L: (three-year experiment) and Lolium perenne L. (one-year experiment) were planted in the 5L pots. Soils were treated with ash or ash combinated by superphoshate and flue gas desulfurization gypsum. For both plants, we evaluated the plant growth, biomass production and content of macro, micro and toxic elements in the biomass and in the soils.

Is the fur good predictor of intoxification of European beaver (Castor fiber) populations?
Faltová, Karolína ; Vorel, Aleš (advisor) ; Korbelová, Jana (referee)
This thesis deals with the burden of European beaver (Castor fiber) populations with risk elements in three areas of the Czech Republic and one area in Slovakia. There were investigated concentrations of heavy metals (Cd, Zn, Fe, Cu, Pb and As) in the kidneys, livers, lungs, hearts, muscles and fur of 19 found dead beaver individuals. Furthermore, their food was analysed to determine the contamination of their areas of origin and discover, which organ reflects the observed concentrations of Cd the best. The main aim of the study was to determine whether the analysis of hair could be used as a non-invasive method to reflect the concentrations of heavy metals in beaver populations in future. The results were conclusive only for As, whose concentrations in the hair was the second highest and correlated with the content of As in the lungs, which contained the highest concentrations of arsenic. Cadmium in the fur showed a reverse structure compared to the content of Cd in kidney and liver. There were found significant differences in the contamination with heavy metals between beaver populations and their environments. Analysis of the fur is not proved for most of the elements and it is necessary to investigate further non-invasive methods to determine the load of toxic elements on beaver populations.

Testing of bioeffectors on phosphorus mobility in soils
Holečková, Zlata ; Balík, Jiří (advisor)
Crave for increase in agricultural production over the past sixty years reflects in widespread use of mineral fertilizers. Due to the growth of the world population an increase of overall demand for feed and food is expected. Limited availability of cultivatable soil and increasing dependance on mineral fertilizers can be also anticipated. It is therefore important to find alternative strategies for plant nutrition. In 2012, the project of cooperation between several universities in Europe was revealed. This project examines the use of bioeffectors in crop production. Use of these substances should help to reduce the input of mineral fertilizers used in agriculture and improve land usage. Thesis will perform testing in real conditions of different geographic locations. The main objective is to develop new approaches to the use of so-called bioeffectors based on the mechanism of action of living microorganisms and active natural substances. Bioeffectors may be, depending on soil and climatic conditions, a key factor for overcoming limitations in the availability of nutrients. They can contain microorganisms (bacteria, fungi) and active natural compounds (digest from soil or compost, microbial residues, plant extracts, metabolites from biological processes, dried herb material or seaweed). These substances are developed for a wide variety of crops (e.g. corn, wheat and tomatoes). Their effectiveness consists in nutrients mobilization from less accessible forms in the soil. The thesis is mainly focused on the impact of bioeffectors on various forms of phosphorus in the soil. Phosphorus in the soil belongs to essential elements necessary for the growth and development of plants. Despite its necessity in plant metabolism is its content in the soil relatively low. A higher phosphorus content is in most samples of soil mainly in the surface area because an increased biological activity occurs there causing the accumulation of organic material. Some influence can be also observed in connection with application of organic and mineral fertilizers. Amount of phosphorus in soil may vary depending on parental rock type, texture and land management (the ratio of P supplied and type and method of land cultivation). Above mentioned influences even have an effect on relative amount of organic and inorganic forms of phosphorus. Three basic groups of phosphorus contained in the soil can be described: inorganic phosphorus compounds, organically bound phosphorus and exchangeable absorbed phosphorus. The amount of phosphorus bound in the fractions depends mainly on the time of fertilizer application, including the impact of earlier interventions. For these reasons, it is necessary to execute detailed analysis of the various forms of phosphorus in the soil after application of mineral fertilizers together with bioeffectors. In this dissertation variety of pot and field experiments will be set up, where samples from each variation of soil and plant will be separated and researched. Samples will be analyzed and amounts of phosphorus will be measured.
