Comparative performance of late stream inoculants in grey cast iron using thermal analysis
Chyla, Ondrej ; Bouška, Ondřej (referee) ; Roučka, Jaromír (advisor)
This diploma thesis in the theoretical part deals with classification of cast iron, problems of gray cast iron production, methods of inoculation and valuation of the gray iron quality by means of thermal analysis. The aim of practical part was to investigate effectiveness of inoculation of two different inoculants using thermal analysis. In terms of mechanical properties, hardness and ultimate tensile strength were measured. Metallographic specimen were evaluating by means of image analysis software.

Alternative nitrogen nutrition of plants
Mikanová, Olga ; Šimon, Tomáš
The methodology provides the basic information about the usability of nitrogenfixating bacteria. The methodology describes procedures of the isolation and screening of beneficial soil bacteria Azotobacter spp. and Rhizobium spp. It also provides recommendations to promote biological nitrogen fixation. The methodology also represents the use of inoculants as a necessary part of modern farming practices.
