1	Synthesis and characterization of micro- and mesoporous materials for low temperature selective catalytic reduction of nitrogen oxides Kasongo Wa Kasongo, Jean B. January 2011 (has links) Doctor Educationis / In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different oxidation number. Only a single metallic phase catalyst could be prepared successfully by using ion exchange. / South Africa Catalysis NOx DeNOx Microporous Mesoporous MCM-41 H-Beta-25 Wet impregnation Ion exchange Theoretical loading Calculated loading Physicochemical
2	Experimentální stanovení zatížení letounu / Experimental load definition Dratva, Jakub January 2018 (has links) The thesis is focused on experimental load definition of an aircraft. Especially is measured bending moment is measured on wing during the flight. The thesis includes theoretical basis for strain gauge measurements and procedure of statistic evaluation. For each of flight maneuvers, there are theoretical wing loads calculated and then the values are compared. The end of the thesis shows proposals for improvement of used method of flight possible repeated measurement.
