Production and elimination of superoxide radical in relation to the compatibility of snails and trematodes
Cibulková, Lucie ; Skála, Vladimír (advisor) ; Nývltová, Eva (referee)
Almost all trematodes use snails as the intermediate host in their life cycles. To survive within the host, they have to efficiently avoid defense reactions of its immune system. The most important effector cells, haemocytes, produce reactive oxygen species with the first molecule known as superoxide radical. Various snail species produce different levels of these radicals in relation to the compatibility with the invasive trematode species. The parasite decreases the levels of toxic radicals by using antioxidant enzymes including superoxide dismutase which catalyzes transformation of superoxide radical into hydrogen peroxide. This dismutation reaction is the first step during the oxidative burst and likely influences survival of trematodes within the host. Based on the current knowledge the production and elimination of superoxide radical in relation to the compatibility between snails and trematodes have been described thoroughly for a few models such as for example Biomphalaria glabrata-Schistosoma mansoni. However, this interaction appears to play a key role and, therefore, it deserves more attention in another models as well. Key words: trematodes, snails, compatibility, haemocytes, oxidative burst, antioxidant enzymes, superoxide dismutase, superoxide radical

The methodology for the selection of appropriate restoration work
Machačko, Luboš ; Gláser, Petr ; Bartoš, L. ; Bayer, K. ; Ďoubal, J. ; Justa, P. ; Vojtěchovský, J. ; Krhánková, K. ; Vácha, Z. ; Wichterlová, Z.
The aim of this methodology is to present a recommended procedure which leads to selection of optimal restoration intervention. Selection of the appropriate procedure and method of restoration and reconstruction is the primary prerequisite for the quality and efficiency of future work.

Vzájemná kompatibilita entomopatogenní houby \kur{Isaria fumosorosea} s dalšími druhy entomopatogenních hub
OUŠKOVÁ, Šárka
This thesis is focused on evaluation of the compatibility of entomopathogenic fungus Isaria fumosorosea with different species of entomopathogenic fungi and mycoparasitic fungi at different temperatures. The strains of species Beauveria bassiana, Metarhizium anisopliae, Lecanicillium muscarium, Coniothyrium minitans and Clonostachys rosea f. catenulata were selected for experiments base on compatibility. The results showed that combination of I. fumosorosea with species L. muscarium is compatible. The species do not limit to each other in the environment at all temperatures (15, 23 and 25 °C). On the other side, fungus I. fumosorosea in combination with other species have affected their growth and spore production. The efficacy of entomopathogenic fungi against larvae Tenebrio molitor was evaluated. The most effective species against larvae were species I. fumosorosea, B. bassiana and M. anisopliae. On the contrary, the smallest effective was observed after infection larvae by L. muscarium. Mycoparasitic fungus C. rosea f. catenulata was not able to directly infect larvae of T. molitor. This species did not infect healthy larvae. However it is able to infect weakened individuals or is growing as saprotrophs on the cadavers.

Parameters of BGA-type interconnection joints ceramic Al2O3 substrates
Somer, Jakub ; Švecová, Olga (referee) ; Nicák, Michal (advisor)
This project deals with questions related to parameters of solder balls, used on BGA packages, on ceramic substrates. First part of this project contains general characteristic of solder balls, their properties and usage. In the following part there are described technologies and methods used during the experiment including the design of test substrate. The last part is dedicated to practical examination of compatibility of selected conductive pastes, solder pastes and fluxes during vapor reflow soldering. At the end of this work the selection of materials, assembly, soldering and microsections are described.

Development and testing of high performance concrete for subtle structures
Myšičková, Lucie ; Cikrle, Petr (referee) ; Bílek, Vlastimil (advisor)
Thesis describes properties of HPC compared to concretes of normal and high strength. It further describes the input materials and the procedure for designing the composition of the mixture. It gives examples of already completed structures made of HPC. The experimental part describes the optimization of concrete mix and production of specimens. In the end results of testing the properties of the developed mixes from tests of dynamic and static modulus of elasticity, compressive strength and tensile strength by bending are described.

Octave and Matlab comparison in terms of basic mathematics
Zahradník, Radek ; Grepl, Robert (referee) ; Krejčí, Petr (advisor)
How is mankind grow older, its knowledge about nature, which in it lives, is getting deeper. Unfortunately human brain in itself became short for solving modern problems and we have to help ourselves with computers and modern computerised methods. But computers themselves can not solve the problems. We need to equip them with adequate software. Goal of this work is to compare Octave and Matlab systems in part of compatibility and in the solvings of practical problems.

Repair formulations for fine-grained stone arte-facts
Tišlová, R. ; Novotná, Adéla
Stone restoration practice continuously deals with the problem of the selection of suitable repair materials. In establishing the requirements that guide their specification, the fundamental aim should always be to achieve the best compatibility between the substrate and the repair. When dealing with the restoration of stone, several aspects must be taken into consideration: not only the way in which compatibility influences the durability and structural and environmental resistance of the repair, but also the properties of the stone substrate itself must be considered. Compatibility is a highly complex problem but when considering the above mentioned aspects, functional compatibility – the compliance between physical and mechanical characteristics of the materials – is the most critical in prolonging the sustainability of the repair.
