In this thesis, the author deals with a topic focusing on use of plasma screens and plasma technologies in contemporary news channel CT24 broadcasting. The thesis is contained of theoretical and practical part. In the theoretical part, the author summarizes existing findings of the television news field. The theoretical part includes a basic definition of television news and its subsequent changes, primarily because of digitalization process. In the connection with digitalization, the author also deals with new formats of television news, such as TV graphics. In the second half of theoretical part, the author focuses on characteristics of Czech Television and CT24 news channel. It contains of brief description of programs and studies, from which CT24 broadcasts, and which are closely related to use of plasma technologies. In the practical part, the author then focuses on the specific use of plasma technologies in the broadcast of CT24 channel. First, the author offers a basic division of what these elements are used for in broadcasting. Based on his own experience and interviews with Czech Television staff, he then describes the use of plasma technologies in individual programs and studios and offers their comparison.

Diploma thesis deals with glass fiber surface modification using plasma-enhanced chemical vapor deposition in order to prepare functional interface that enhances the properties of polymer composites. The effect of deposition conditions on shear strength was observed with respect to the chemical composition of the deposited film. Thin films were deposited on planar substrates and fibers using monomer tetravinylsilane in a mixture with oxygen at selected power of plasma discharge. Chemical composition of prepared material was analyzed by infrared spectroscopy. Planar substrate film adhesion was measured using the scratch test. The composite sample was prepared by embedding the surface modified fibers in unsaturated polyester resin, followed by the curing process. The cured composite sample underwent the short beam shear test.

aaaaaRare earth elements (Sc, Y and group 15 lanthanides) and their compounds currently have significant practical use in metallurgy, glass industry, as highly active catalysts for the production of so-called. NiMH batteries, alloys for the manufacture of permanent magnets and e.g. moderators rods in the nuclear energy, but above all they have an irreplaceable role in modern electronics for phosphors TV screens, CRT earlier today, PDP and LCD monitors and displays, tablets, mobile phones etc., which give them a high-quality picture and sound. Unlike most base and precious metals are concentrated in the conquerable ore deposits, occur in the form of compounds as part of mixed minerals in the rarely economically exploitable concentrations, a mining and processing is costly and negative impacts on the environment, paradoxically towards the title but their overall content in the crust is relatively high, the average concentration in the range of about 150 to 220 ppm. The main world producer of REE, China, in 2010, significantly reduced exports by 40 %, making prices of some REE increased up to 1500 % during the month. Demand for REE is growing, so often talks about the recycling of valuable materials back into production, as called. "Urban mining", ie "urban mining", thereby reducing the amount of...
