Dependence of derived fibrinogen on values of DH from APTT and QUICK(PT) methods
Klus, Michal ; Zapletal,, Ondřej (referee) ; Škutková, Helena (advisor)
Hemocoagulation, blood coagulation, is an important indicator of hemostatic balance in the human body. There are many ways how to investigate blood clotting. In practice, next to the tests investigating time of coagulation cascade from view of internal way (APTT – activated partial tromboplastin time) and external way (PT – prothrombin time) is often used determining of fibrinogen concentration by Clauss method. Derived fibrinogen method determined fibrinogen concentration, too, by subtracting form the clotting curve in PT test. The reaction for Clauss method is not necessary here. Derived fibrinogen is not used much in practice. This is the reason, why the thesis related to this project will try to find relationship between concentration of fibrinogen and standard tests APTT and PT. Clinical data will be used for this.

Aplication of SPM in study and modification of ultrathin films Pt, Co and graphene
Lišková, Zuzana ; Červenka,, Jiří (referee) ; Bartošík, Miroslav (advisor)
This diploma thesis deals with the preparation of the very thin films and their investigation by scanning probe microscopy methods. The ultrathin films of Pt on Pt(111) were created by pulsed laser deposition and the ultrathin films of Co on Pt(111) were deposited by thermal evaporation. The coverage of the substrate was much smaller than one monolayer (in order of hundredths of monolayer). The nucleation theory was verified by these experiments using so-called Onset method. Further graphene sheets were prepared on layer of Si/SiO2 by the mechanical exfoliation from the graphite crystal. The fabricated graphene sheets were studied by micro-Raman spectroscopy, microreflectometry, atomic force microscopy and similar techniques. These methods proved the thinnest graphite layers were consisted of two graphene monolayers.

3D tomography of thin film catalysts by means of FIB/SEM techniques
Dinhová, Thu Ngan ; Matolínová, Iva (advisor) ; Khalakhan, Ivan (referee)
One of the actual problems of today society are decreasing sources of fossil fuels. They are raw minerals and by their burning is energy produced. Regarding to the importance of energy in todays world, it's necessary to find an alternative way how to generate energy. A possible solution to this problem are fuel cells, which work on the principle of converting chemical energy into electric energy. At this moment, the development of fuel cells is in progress. In this bachelor thesis, we are concerned with morphology of catalytic layers Pt/CeO2 deposed on a polymer membrane for hydrogen fuel cells. By using of tomography method with focused ion beam system (FIB) we are creating three-dimensional models of their surface structures. 1

Changing Autonomy in times of PT: Explaining the rise and fall of the Southern Giant
Stipic, Igor ; Gotz Betancourt, Shirley (advisor) ; Zajíček, Miroslav (referee)
The objective of this thesis is to analyze the concept of autonomy, taking as the case study Brazil under the Workers Party Government (2003-2016). Approach that will be taken aims at combining perspectives of Latin-American structuralism with those of realism and interdependency. Thesis essentially concentrates on two specific issue areas: global economy and international politics. By constructing a theoretical framework, I aspire to identify and analyze various factors considered to have a direct impact on the study matter. In doing so, I consider the behavior of distinct variables and their effect on the degree of autonomy. Finally, thesis addresses problems of international insertion for peripheral countries, considering possibilities and limits of truly autonomous action.
