Forming Technology of Thin Sheets
Musil, Zbyněk ; Žák, Ladislav (referee) ; Dvořák, Milan (advisor)
This bachelor‘s thesis deals with technology of mechanical working of the sheetmetals by cutting for rotary and non-rotary single parts. The first part deal with common dissertation about surface mechanical working, mainly about cutting and meaning of cutting gap in accordance with final cutting. The second part deals with transfer of the new pieces of knowledge from foreign technical literature of surface mechanical working. In the last part there is done an aplication on the particular component.
Influence of process parameters in forward extrusion on the initiation of chevron cracks in material
Musil, Zbyněk ; Kubík, Petr (referee) ; Petruška, Jindřich (advisor)
This Master’s thesis deals with the influence of process parameters in forward extrusion on the initiation of chevron cracks in material by numerical simulation. Solution was executed by ANSYS 11 and the influence of fiction, angle of reduction, reduction and numbers of extrusion operations was solved for the 12 050.3 steel by the chosen conditions.
Synthesis and the structure-activity relationship study of photosensitizers from azaphtalocyanines group
Musil, Zbyněk ; Doležal, Martin (advisor) ; Hartl, Jiří (referee) ; Lang, Kamil (referee)
We have prepared a number of variously substituted precursors based on pyrazine-2,3- dicarbonitrile, phthalonitrile and quinoxaline-2,3-dicarbonitrile. These substances formed macrocycles and each of them was separated (if possible), purified and sufficiently characterized. In this way were prepared several series of products which were used to elucidate the influence of structural changes on physical and photodynamical properties. We found out that the zinc complexes of azaphthalocyanines which were substituted with bulky groups binding to the macrocycle core via heteroatom of sulphur were the best from the point of view of photodynamical properties. These substances were characterized by high production of singlet oxygen, sufficient photostability, maximum absorption at longer wavelenght and poor aggregation which provides a high-quality incorporation into unilamelar liposomes. Based on aforementioned results we prepared photosensitisers containing one funtional group which could be possibly used as the third generation photosensitisers. By the incorporation of four benzene cores into tetrapyrazinoporphyrazine macrocycle was the absorption maximum shifted to the range of app. 750 nm which is cinsidered as optimal from the point of view of photodynamical effect in living tissues.
Typology of the EU asylum policy in relation to asylum seekers
Musil, Zbyněk ; Janská, Eva (advisor) ; Šánová, Lucie (referee)
The aim of the thesis is an outline of the evolution of European asylum policy of asylum policies towards asylum seekers within seven EU member countries since 1990. The brief description of common trends in asylum policy in European Union and EFTA (European Free Trade Zone) member countries and outline of current policy towards asylum seekers, where current living conditions are part of it. Also the position of asylum seekers in specific spheres such as education, right to work, financial and social security, health service and accommodation is discussed. Another goal is to compare the practices in the asylum policy in the Czech Republic with the policies towards the asylum seekers of other six EU member countries - Denmark, France, Germany, Republic of Ireland, the Netherlands and the United Kingdom. There is also an introduction of governmental steps which deal with the immigration law or asylum law and therefore regulate the living conditions of asylum seekers in their country.
