Evaluation of combine harvesters John Deere 670i and Claas Lexion 770
JURÁSEK, Martin
This bachelor thesis evaluates the John Deere 670i and Claas Lexion 770 combine harvesters in terms of cost, threshing quality, losses and area performance. The thesis describes the functions of the combine harvesters and their technological description and practical applications. The parameters calculated in the bachelor thesis are pre-harvest and harvest losses, area and weight performance, mass yield, travel speed, crushing quality, fuel consumption and fixed and variable costs.
Monitoring of photocatalytic activity
Jurášek, Martin ; Drbohlavová, Jana (referee) ; Veselý, Michal (advisor)
Bachelors thesis deals with kinetics of redox dye 2,6-dichloroindophenol degradation. Thanks to photo-reduced form is colourless, it’s suitable to use it for photocatalytic activity rapid assessment of the thin titanium dioxide layers. The thin layers of TiO2 were prepared using nano-crystalline titanium dioxide suspension with amorphous silica. These layers, including layers of redox dye, were deposited by material printing process. The rate of redox dye photo-reduction was monitored in dependence of number of thin titanium dioxide layers at different UV irradiance. Redox dye concentration was studied using UV-VIS spectroscopy.
