Trends in the balance and material flows of phosphorus in the Czech Republic.
Hejzlar, Josef
In developed countries, many voices call for increasing the recycling of phosphorus (P) that is a strategic raw material for agriculture and other production sector; phosphorus is also causing environmental problems, for example. eutrophication. Using the methodology of material flow analysis, van Dijk et al. (Sci. Total Environ. 2016, 552: 1078-1093) quantified the main flows and stocks of P in 27 states of the European Union. The contribution presents and discusses data from that publication for the material flows P in the Czech Republic (CR) and compared with the EU. The P balance of CR shows the dependence on imported P through mineral fertilizers (1 kg/ca/yr), food and feed (1.5 kg/ca/yr) and also draws attention to significant environment losses and unused recycling potential. For example, municipal sludge (0.4 kg/ca/yr) and bone meal (0.25 kg/ca/yr) could replace 70% of the P amount in applied mineral fertilizers. P recycling rate in CR in comparison with EU-27 is below average (68% in livestock production, 21% in food production, 10% for human consumption). Agricultural production in CR still uses P reserves in the soil of mineral fertilizers in the past.

Factors affecting unemployment in selected groups in region Ústí nad Labem
Pešek, Václav ; Maitah, Mansoor (advisor) ; Anna, Anna (referee)
This thesis examines the factors that affect unemployment in the Usti region in selected groups. The document is divided into two main parts, the theoretical part and analytical part. The issue of unemployment is one of the most essential macroeconomic indicators of each country, therefore require closer observation and analysis.
The theoretical part (theoretical background) is theoretically and generally focused on unemployment as such. There is further characterized by the concept of unemployment and theoretically explain all aspects that bind to this issue (the types and causes of unemployment, consequences and impacts, the unemployment rate and the method of measurement, labor supply and demand, labor market and human capital).
The practical part of this work (analytical part) deals with the detailed analysis of certain factors that affect the overall unemployment rate in the Usti region in pre-selected populations. It is therefore a finding of dependency between certain factors and the overall unemployment rate in terms of both quantitative statistical survey data and qualitative theory, the author of this work.

Dynamics and spatial extension of recent landslides at the foot of Krušné Hory Mts.
Burda, Jan ; Vilímek, Vít (advisor) ; Kirchner, Karel (referee) ; Šilhán, Karel (referee)
Dynamika a rozšíření recentních svahových pohybů na úpatí Krušných hor | Abstrackt 1 ABSTRACT Recent mass movements currently comprise one of the main morphogenetic processes in the extensive anthropogenic relief of the foreground of the Krušné Hory Mountains in the Czech Republic. These mass movements result in several types of deep- seated slope failures, depending on the type of movement, lithological, structural, and geotechnical conditions and the water saturation of the landslide material. This thesis presents broad set of various methods of geomorphology, geophysics, engineering geology, dendrogeomorphology and geodesy in an attempt to fully understand the problem of slope failures in the Jezeří area located at the boundary between the Krušné Hory Mountains and the Most Basin (Czech Republic). An interdisciplinary approach has enabled an in-depth review of both the dynamics and development of recent slope failures as well as morphology and structure of slope failures. There are two sectors - Southeast and Southwest - with different types of slope failures. In the Southwest sector, mass movements occur in thick colluvial mantle and weathered Tertiary claystones. The main factors influencing their development include rainfall culminations, groundwater flowing from the valley of Šramnický Brook and...

Statistical analysis of resocialization care after prison release
Dlouhá, Šárka ; Hlavsa, Tomáš (advisor) ; Michal, Michal (referee)
The level of crime has to be regulated in order to prevent the crime to cause major damage to society. Therefore it is profitable to address criminal recidivism as well. Recidivism is caused by a complicated process of reintegration of people with criminal records back to society. The main goal of this thesis was to find the main factors affecting reintegration process of people after incarceration. The thesis is trying to reach the results by quantitative research, specifically examining the frequencies and dependence of categorical variables. The main factors which influence the reintegration process of people with criminal past are unemployment and indebtedness. These elements are affected by certain demographic factors. These factors also influence the type of criminal activity and the probability of criminal recidivism.

The Support for Children with Developmental Dysphasia in a Preschool Educational Institution
ČERMÁKOVÁ, Irena
The aim of this bachelor´s thesis is to contribute to the improvement of the support for children suffering from their developmental dysphasia in the pre-school education establishment. The theoretical part is based on the development trends of children?s speech, then I characterized the aspects of the impaired speech developments and finally I focused on developmental dysphasia issues from the diagnostic and therapeutic viewpoints, as well as on the issues of the education and support for children with developmental dysphasia. The practical part contains case studies concerning three children in order to reveal positive as well as risk factors of the education held in a special kindergarten logopaedic class. The special attention was paid to their educational progress depending on pedagogical activity, mutual co-operation among kindergarten, the family and advisory centres. The interviews with the child?s mother form the part of the progress - evaluating research.

Vliv odvodnění a vegetace na množství a diverzitu metanogenů v rašeliništích
LÍSALOVÁ, Olga
This work deals with attribute of microbial communities, especially methanogenic Archaea in pristine and drained peatlands. Methanogens are strictly anaerobic microorganism thus they live in deeper anoxic layers of peatlands. Therefore, the aim of this study was to determine how the drainage affects the amount and diversity of methanogens depending on different depths, types of peatlands and litter type.

Význam sialovaných glykoproteinů pro klíště \kur{Ixodes ricinus}
ONDRUŠ, Jaroslav
Sialic acid is a highly abundant and a common component of vertebrate glycans, where it can be found in the terminal positions of the cell surface glycoconjugates. The amount of sialylated glycoconjugates as well as their complexity vary between both different species and different tissue types within one individual. Considering the vertebrates, these well studied structures are know to be important for cell-cell interactions, cell adhesion and immunity. In contrary, sialic acid in arthropod glycans has been identified only in a limited number of species. In obligatory blood feeding parasites such as ticks, distinguishing between sialylated glycoproteins of tick and host origin is challenging due to huge volumes of ingested blood containing heavily sialylated structures of host origin. In the tick Ixodes ricinus, the presence of minor amount of tick´s sialylated structures has been shown previously in the ovaries and salivary glands, however, their role remains completely unknown. In this thesis, we study the importance and role of both the tick-originating and the host sialylated glycoproteins for I. ricinus, the tick commonly found in Czech Republic. We show that the tick-originating sialylated glycoproteins are present in I. ricinus eggs, and that their amount changes over time after laying the eggs. Furthermore, these molecules were localized in cryosections of 14 days old eggs and in the larvae using confocal microscopy. In addition, we shed some further light on the role of sialic acid for ticks in the tick blood meal. According to our results, the glycan part of glycoproteins is the key in recognition of these molecules by tick cells.
