Our modern industrialized society increasingly requires new structural materials\nfor high-temperature applications in automotive and energy-producing industrial\nsectors. Iron-aluminides are known to possess excellent oxidation and sulfidation\nresistance as well as sufficient strength at elevated temperatures. New Fe-Al-based\nmaterials will have to meet multiple casting, processing and operational criteria\nincluding high-temperature creep strength, oxidation resistance and room-temperature\nductility. Such desirable combination of materials properties can be achieved in multi-phase\nmulti-component superalloys with a specific type of microstructure (the matrix contains\ncoherent particles of a secondary phase - a superalloy microstructure). In order to design\nnew Fe-Al-based superalloys, we employ a state-ofthe-art theory-guided materials design\nconcept to identify suitable combinations of solutes.

Dental Hygiene impact on oral health guality of patients with dental implants
Pavlů, Jana ; Novotná, Jindra (advisor) ; Kulhavá, Miluše (referee)
Dental hygiene and oral health is a topic that is currently discussed.. Dental health reflects the overall health of humans and vice versa damaged teeth can significantly reduce health and quality of life. The results clearly confirm that the largest share of the poor quality of oral health is poor oral hygiene. That's why prevention is the most effective tool, provided that the patient is properly educated and motivated to take responsibility for the state of his teeth. From my experience at Dental emergency. We know, that the reality is different. Bachelor thesis is focused on demonstrating the positive impact of dental hygiene. The theoretical part deals with the anatomy and physiology of teeth, briefly describes the most important oral diseases caused by malhygiene. It introduce a possible solution of tooth loss using dental implant and prosthetics. Empirical part is divided into two parts. The first one is focused to demonstrates the positive effect of dental hygiene of patients with established dental implants. This particular group of patients was chosen on purpose, because these patients are properly and repeatedly instructed to care intensely of their implants, because the lifetime of the implant after surgery depends on their care. In a random sample of fifteen patients with dental...
