The study of influence of the measurement method on static angle of repose of free-flowable excipients
Mrázková, Aneta ; Šklubalová, Zdeňka (advisor) ; Svačinová, Petra (referee)
Charles University, Faculty of Pharmacy in Hradci Králové Department of: Pharmaceutical technology Supervisor: doc. PharmDr. Zdeňka Šklubalová, Ph.D. Consultant: Mgr. Žofie Trpělková Student: Aneta Mrázková Title of Thesis: The study of influence of the measurement method on static angle of repose of free-flowable excipients. Good flow and consolidation properties of powders represent significant characteristics of pharmaceutical excipients They are important for manufacturing of powders into solid dosage forms. Flow behavior of 6 free flowing excipients was evaluated in this diploma thesis. The main target was a study of the influence of the masurement method and the orifice size of a conical hopper on static angle of repose (AOR). The automatic tester and the prototype for measuring AOR having orifice sizes in a range of 6-15 mm were used for the measurement. A significant difference between the results of these two methods (P <0.01) was observed. The decrease in AOR was detected when increased the orifice diameter, the effect was significant (P <0.01) only in automatic tester for two out of six measured powders. Surprisingly, the significant influence of the orifice size on AOR was registered for a sweetener Palatinose with protype equipment.

Fitness training in tennis
Mrázková, Aneta ; Engelthalerová, Zdeňka (advisor) ; Přibyl, Ivan (referee)
The graduation thesis deals with fitness training of children tennis players. The fitness training plan to improve fitness and skill levels of an experimental group has been designed by the author of the thesis on the basis of findings of scientific literature. The research part of the thesis was conducted by experiment. The experiment compares the differences in growth of performance between the experimental group and the control group and answers the basic question of the thesis if the designed plan is useful and fully operational for fitness training of children tennis players. In the conclusion the author presents the evaluation of her findings for further work with children.
