Utilization of advanced rheological techniques for the study of biological systems
Krňávková, Šárka ; Kráčalík, Milan (referee) ; Smilek, Jiří (advisor)
A new method for determining viscoelastic properties on the interfacial interface called interfacial rheology was intoduced and investigated. Measured data were compared with data from tanziometer for model system of surfactant. Three concentration renge of surfactant, namely SDS (anionic), TTAB (cationic) and Tween (nonionic), were measured. From the measured data the influence of structure, critical micellar concentration and charge on the viscoelastic properties of the interfacial interface was determined. Furthermore, this new method was used for biological systems and specifically for biofilms of two bacterial strains. First, the viscoelastic properties of biofilms on the agar were determined, and the viscoelastic properties dependence on temperature

Design of manufacturing technology for plastic hung
Popelka, Jan ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
The aim of my graduation theses is to work up the literature search of polymer processing. To give a short summary of their structure, characteristic and fabrication technique. Then to make a structural design of injection mold for producing the scheduled aim and motivate this design with requisite calculation for construction of the tool, a choice of injection machine and rundown of injection cycle. At the end of my work is this aim economically reviewed and compared with alternative form of structural design.
