Mesophilous grassland butterflies of European interest under climate changes (Lycaena dispar, Lycaena helle, Phengaris nausithous, Phengaris teleius, Euphydryas aurinia)
Vrba, Pavel ; Faltýnek Fric, Zdeněk ; Rindoš, Michal ; Hájková, K. ; Konvička, Martin
Methodological material summarizing variants of the habitat conservation principles for butterflies inhabitting mesophilic and humid grasslands under various scenarios of climate change. The species of interest, protected by the EU Habitats Directive, are Euphydryas aurinia, Phengaris nausithous, Phengaris teleius, Lycaena dispar and Lycaena helle. It includes the predictions of suitable locations for spontaneous or assisted colonization.
Dry grassland butterflies of European interest under climate changes (Colias myrmidone, Parnassius apollo, Phengaris arion)
Faltýnek Fric, Zdeněk ; Konvička, Martin ; Rindoš, Michal ; Sucháčková Bartoňová, Alena ; Spitzer, Lukáš ; Vrba, Pavel
The methodology summarizes the principles of the habitat conservation of several butterflies - Phengaris arion, Parnassius apollo and Colias myrmidone, species specialized to dry grasslands, rock screes and similar habitats, under different scenarios of climate change. Maps of future climatically suitable habitats are included, together with an analysis of the possibilities of assisted colonization.
Endangered butterflies of lowland forests under climate change
Konvička, Martin ; Beneš, Jiří ; Číp, D. ; Sobík, D. ; Spitzer, L. ; Faltýnek Fric, Zdeněk ; Rindoš, Michal ; Vrba, Pavel
The material compiles conservation measures and methods for the care of endangered butterflies of open forests, protected by the EU Habitat Directive in the Czech Republic and under climate changes. These species are Euphydryas maturna, Lopinga achine, Parnassius mnemosyne, Coenonympha hero, and partially also Zerynthia polyxena. It results from predictions of vegetational and climatic changes of forest habitats, and outlooks of forest and water management conditions.
Immunological features of esophageal carcinoma in prognosis and therapy
Šnajdauf, Martin ; Lischke, Robert (advisor) ; Vrba, Radek (referee) ; Stříž, Ilja (referee)
Esophageal cancer belongs to the gastrointestinal malignancies with the worst prognosis. Current treatment options, including surgical resection, chemotherapy, radiotherapy, or a combination of these methods, have low efficacy and the five-year survival rate for patients with esophageal cancer is approximately 10 to 15 %. In the last decade, immunotherapy has become the leading treatment modality for metastatic tumors. However, the success of immunotherapeutic approaches does not only depend on the infiltration of the tumor microenvironment with immune cells but also on the phenotype of these infiltrating cells. The aim of this project was to evaluatethe immunological features of tumor-infiltrating lymphocytes obtained from different tissue compartments (tumor, peritumoral tissue, adjacent healthy tissue, and lymph node) of patients during surgical resection and to compare them with clinical and histopathological data of patients. We observed that the distribution of NK (natural killer) cells, CD8 and CD4 positive T cells was different in each tissue compartment. While the lymph nodes had the highest percentage of T cells, the opposite was seen in NK cells. The proportion of NK cells was the lowest in the lymph nodes. The expression of death receptors FasR and DR3 (death receptor 3) was the lowest...
Medieval Mural Painting in the Doupov Region. Churches of st. Nicolas and st.Wolfgang in Doupov.
Vrba, Martin ; Royt, Jan (advisor) ; Ottová, Michaela (referee)
Středověká nástěnná malba na Doupovsku Abstract This thesis focuses on medieval mural paintings in the area of the Doupov Mountains on two examples, church of St. Nicholas in Nepomyšl and destroyed cemetery church of St. Wolfgang in Doupov. Description of both churches contains historical background of its origin and decoration, including donors. Other parts of thesis deal with present condition of paintings, iconographical and iconological analysis as well as inspiration and analogy. In both cases the largest part takes the Christological cycle in the naves. The medieval paintings from two periods were recently uncovered in the church of St. Nicholas in Nepomyšl. The older of them are dated to the second half of 14th century. Remains of them are in the presbytary of the church. The younger are from the beginning of 16th century. They are in the nave and they are influenced by Cranach's graphics of Passion Cycle. The church of St. Wolfgang in Doupov was built at the end of the 14th century; nevertheless the donor of the paintings was Jan Mašťovský of Kolovraty, who died ca. 1527. After the World War II the German inhabitants were moved away and the military area was founded here. The church was not maintained and perished through the time. The paintings are preserved in the form of transfers, which were...
Inhomogeneous cosmological models
Vrba, David ; Svítek, Otakar (advisor) ; Pravda, Vojtěch (referee) ; Žofka, Martin (referee)
In this work we study inhomogeneous cosmological models. After a brief review of applications of inhomogeneous solutions to Einstein equations in cosmology, we give a short description of the most widely used inhomogeneous cosmological models. In the second chapter we study in detail geometrical prop- erties of the Szekeres spacetime and we are concerned with the interpretation of the metric functions in different types of geometries. In the last chapter we model inhomogeneity in Szekeres spacetime. We derive formula for the density contrast and investigate its behaviour. We also derive conditions for the density extremes that are necessary for avoiding the shell crossing singularity in Szekeres spacetime. 1
Multi-Objective Optimization of EM Structures With Variable Number of Dimensions
Marek, Martin ; Vrba,, Jan (referee) ; Šenkeřík,, Roman (referee) ; Kadlec, Petr (advisor)
Tato dizertační práce pojednává o více-kriteriálních optimalizačních algoritmech s proměnným počtem dimenzí. Takový algoritmus umožňuje řešit optimalizační úlohy, které jsou jinak řešitelné jen s použitím nepřirozených zjednodušení. Výzkum optimalizačních method s proměnnou dimenzí si vyžádal vytvoření nového optimalizačního frameworku, který obsahuje vedle zmíněných vícekriteriálních metod s proměnnou dimenzí – VND-GDE3 a VND-MOPSO – i další optimalizační metody různých tříd. Optimalizační framework obsahuje také knihovnu rozličných testovacích problémů. Mezi nimi je také sada více-kriteriálních testovacích problémů s proměnnou dimenzí, které byly navrženy pro nastavení a ověření nových metod s proměnnou dimenzí. Nové metody jsou dále použity k optimalizaci několika různorodých optimalizačních úloh z reálného světa.
Conceptual design of a heat switch installation into a structure of satellite
Vrba, Martin ; Horák, Marek (referee) ; Mašek, Jakub (advisor)
Tato diplomová práce je zaměřena na sestavení přehledu konstrukcí a teplených cest kosmických lodí a kosmických vozidel, které se v současné době používají. Na základě specifických požadavků a standardů jsou vypracovány koncepční návrhy zástavby tepelného spínače do konstrukce družice. V jednotlivých kapitolách jsou popsány určité členy, které se na vedení tepla podílí a jsou důležité pro navrhované koncepty z pohledu konstrukce. Diplomová práce popisuje postupy výpočtu tepelných vodivostí a rozložení působící tíhové síly do míst uchycení pro jednotlivé koncepty. Na závěr provádí hodnocení a výběr potenciálně nejvhodnějšího návrhu.
The realisation procedure for flood control measures in the selected section of river Oslava
Kopuletý, Martin ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
The thesis is focused on the comprehensive solution of the flood protection measures of the town Oslava on the river Oslava. The territory was subjected to a risk analysis with a graphical representation of risk in the area and potential damage to the property was calculated. In continuity has been proposed appropriate flood protection measure to reduce damage. The economic effectiveness of the measures was carried out and other documentation required for the underlimit tender of the project was elaborated. In the conclusion of the diploma thesis there is another possible use of the diploma thesis.
