Abstract:

The diploma thesis is dealt with a project of a new manufacture method of a bicycle´s part. The part is a brake drum, which is the necessary part of a free-running charge. In an intro-duction of the diploma thesis is described a nowdays manufacture technology and its deficiencies. According to the nowdays manufacture technology was designed a new one, which is based on a cold volumetric shanking. The shanked hemihedron is consequently shaped according to the current technology. After the operation of cold shaping an instrument is projected. The project of the shaping technology is filled up by the calculation of the essential parameters, including an arrangement of the instrument and the process. An economical evaluation of the new process of the brake drum is stated and its advantages and disadvantaged were selected.

Abstract:

Master`s thesis deals with unusual high-pressure-fluid forming technology – hydroforming. There are discussed factors, which are affecting forming process, and there are made conclusion of it for machine design process. There is also made an evaluation of tube hydroforming technology in nowadays. The objective of thesis is to design new forming machine for tube hydroforming and for use in bicycle frames design. The machine is to be determined for manufacturing series up to 1000 pieces. Based on calculations and discussion of hydroforming technology, the best design solution is chosen. Machine is designed as modular conception with pressure multiplication of forming fluid right in die cavity. There is no need to use high pressure pump for forming fluid, used in common machines for tube hydroforming. This leads to cost reduction and so the objective of thesis is accomplished.

Abstract:

This dissertation applies anthropology analysis to study a specie of a tree frog, living in the northern Amazonia, called Kambo. The wax-like substance, which the frog releases upon irritation, is used for its healing potential around the world. A basic conceptual framework is used to analyse the frog from the perspective of modernity, globalisation, and diffusion of cultural dimensions. The dissertation anticipates their influences on multiple parties. The geographical scope of the dissertation is limited on Amazonia and the Czech Republic. Kambo is a host of numerous biochemical interactions; in addition, it is used in socio-material context; in rituals; for gaining, or circulation of experience; or it is part of various techniques of understanding oneself, as described in later works of Michel Foucault. Due to Kambo's alleged participation on creation of human's subjective thinking, the dissertation answers the question on the extent to which Kambo could be responsible, through ethnographic lens. The results show that for those respondents who were experienced Kambo users; using the substance as a potion for treating physiological and mental issues and who were subsequently influenced by New Age movement; Kambo stands as a milestone in their life trajectories. Through the ethnographic research,...
