Tube bending
 Richter, Tomáš ; Peterková, Eva (referee) ; Žák, Ladislav (advisor)
The bachelor thesis deals with the theoretical analysis technologies of bending circular cross-sections. In the first part are said formulas for the calculation of the processes occurring in the blank material and formulas to refine the viability of the operation (or for the assessment of defects). The second part describes the current technologies used for bending pipes of circular (and other) cross-sections.

Hodnocení jakosti bílých jogurtů v závislosti na obsahu tuku vstupní suroviny
 Šťastná, Magdaléna
The thesis aimed to evaluate the quality of plain yoghurt depending on the fat content of the input raw material. The literature part is focused on the legislative requirements and classification of fermented dairy products and plain yoghurt, the raw materials from which plain yoghurt is produced and the basic technological operations of the production process. In addition, mention is made of vegetable fats and their use in the manufacture of alternative dairy products. The practical part deals with the production of yoghurts with different fat contents and different raw materials (animal and vegetable fat). Experimentally produced samples were subjected to Physico-chemical and microbiological analysis. A sensory questionnaire was developed and the yoghurts were sensorially evaluated. Finally, it was assessed whether the use of vegetable fats as a fat additive in the manufacture yoghurts is possible. The result showed that the use of vegetable fats to produce yoghurts of lower fat content would be possible without negative effects on quality, provided that this was allowed by legislation. According to Czech legislation, only a product containing a dairy raw materiál may be called yoghurt. Therefore, this product could not be called yoghurt, but an alternative dairy product.
