Abrasive waterjet machining of composite materials
Chromý, Jakub ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis deals with composite materials and the possibilities of processing these materials by machining technologies. The work is divided into several main parts. The first part deals with the analysis of individual types of composite materials. The possibilities of machining composite materials and available technologies of their machining will be explored. Other parts will focus on the application of unconventional abrasive water jet technology to a specific composite material with an experiment on a sample part made of composite material. At the end of the work there will be a technical and economic evaluation of the experiment.
Ultrasonic machining technology
Chromý, Jakub ; Chladil, Josef (referee) ; Osička, Karel (advisor)
This bachelor thesis deals with a detailed analysis of the possibilities of using ultrasonic technology, introducing a basic theory of physical principle of ultrasound, using various non-destructive applications of ultrasound in engineering It also reviews ultrasonic machining technology and its possibilities at last but not the least.
The role of histone post-translational modifications in the regulation of gene expression in plants
Chromý, Jakub ; Čermák, Vojtěch (advisor) ; Holá, Dana (referee)
Chromatin structure, gene expression and consequently many important aspects of the plant development are under control of epigenetic regulation. Within epigenetic regulation, histones and their modifications play a pivotal role. The N-terminal tails of histones are dynamically modified by covalent post-translational modifications (PTMs). These modifications are key regulators modulating chromatin structure and thus regulating gene expression. In angiosperms, one of the processes finely regulated at the epigenetic level is the flowering. Flowering represents a very complex process, that is relevant for the study of epigenetic regulation as well as for practical application. In this work, I summarize current knowledge of the role of histone PTMs in the regulation of gene expression in plants, focused predominantly on two key regulators of flowering in Arabidopsis - FLC and FT.
