Computational Fluid Dynamic Simulation of Intracranial Aneurysms : analysis of time-depend changes of hemodynamic parameters - the road to clinical use
 Sejkorová, Alena ; Hejčl, Aleš (advisor) ; Vaverka, Miroslav (referee) ; Přibáň, Vladimír (referee)
Computational Fluid Dynamic Simulation of Intracranial Aneurysms Analysis of time-dependent changes of hemodynamic parameters - the road the clinical use Hemodynamics are involved in the genesis of intracranial aneurysms and time- dependent changes of their parameters lead to aneurysm growth, stabilization or rupture. Definition of these changes using computational fluid hemodynamics could significantly contribute to the understanding of aneurysmal development and rupture and could enable the routine use of mathematical simulations. In this study, computational fluid dynamics were performed for nine incidental aneurysms. Five aneurysms were monitored throughout time and factors leading to aneurysm rupture were analyzed. In four aneurysms the influence of the hemodynamics on the growth was defined. Major growth occurred in areas of low wall shear stress and oscillatory index. These areas increased in size during growth time. Contrary to this, neck shape remodeling occurred in areas with large wall shear stress and pressure. Throughout the follow-up of ruptured aneurysms, the minimal wall shear stress decreased, and the area of low wall shear stress increased significantly. The results indicate that decreasing values of minimal wall shear stress and increasing values of low wall shear stress area...

Awareness of the South Bohemian Region of the use of cannabis
 CAJZOVÁ, Jana
The subject matter of my bachelor thesis is Awareness of the South Bohemian Region of the use of cannabis. Work is interested in various themes related to cannabis in many ways, which is today more current than ever. The thesis refers to legislation at the begining , following chapters involve history, characteristics of cannabis as plants, the clinical use of plants, cannabis as a drug and finally the use of cannabis in different spheres, from the food to construction, textile or cosmetic industry. In the practical part four objectives have been set. The aim was to find out what is the opinion on the matter of hemp, how is awareness of cannabis and determine what experiences people have with cannabis and how they approach to marijuana as a drug. The work includes quantitative research, which is based on a method of interrogation. The questionnaire was compiled according to the research assumptions and published via the Internet so many people had access to it. Within a week I managed to reach the 185 respondents. Bachelor thesis can serve to enrich and completion of current information on issues relating to cannabis.
