New matrices for MALDI-MS analysis of lipids
Macháčková, Petra ; Cvačka, Josef (advisor) ; Volný, Michael (referee)
In this work focused on research of new matrices for MALDI-MS analysis of lipids several organic salts were tested as potential matrices for hydrocarbons and wax esters. It was shown previously that the effective ionization of lipids occurs in conjuction with a lithium cation to form adducts [M + Li] + . Therefore, lithium salts of aromatic acids were synthesized. Matrices were evaluated according to their MALDI properties and compared with lithium 2,5-dihydroxybenzoate, which is proven matrix for MALDI analysis of lipids. It was found that effectiveness of matrix depends on presence of hydroxyl group in matrix molecule. The best results were achieved with lithium vannilate, even in comparison with lithium 2,5-dihydroxybenzoate.

Design of Table Fan
Macháčková, Petra ; Rubínová, Dana (referee) ; Křenek, Ladislav (advisor)
The topic of my Bachelor's project is to draft a design of table fan. The main idea is to be innovative while meeting the technical, esthetic and ergonomic requirements and fulfilling psychological and economic functions. The drafted table fan should take advantage of the innovative technology of bladeless fans. The table fan should function as an appropriate addition to a modern interior. The objective is to combine the original design with modernization of the machine while fulfilling the general requirements of industrial design.

Area of ethics in Egon Bondy's philosophy
Macháčková, Petra ; Zika, Richard (advisor) ; Holeček, Tomáš (referee)
Area of ethics in Egon Bondy's philosophy is a kind of treatise and interpretation mainly of Bondy's nonsubstance ontology apart from philosophical antropology and the ethics. In this thesis comes out that nonsubstance ontology as a presentation of reality without any transcendent principle determining the view and continuity of reality is very important for each human. Human has an opened perspective of independent behaviour and can find the real sense of own human being. According to Bondy's meaning the human makes a part of ontological reality which has spontaneously developed to the reality with present rationality. Nevertheless the human is not a wholy rational being yet but neither only a biological being. Human is in advanced stage leading to the future type of human called posthuman. Posthuman needs to live in such reality where he can self-realized and which can reflect his specifics to the others spaces. All these conditions are possible and enabled in one area, the ethics. The kind and range of the ethics area is the key aspect of this thesis.

Choroby jehlic borovice lesní Pinus sylvestris v NPR Toulovcovy Maštale, LS Choceň
Macháčková, Petra
The main objective of this bachelor thesis is to process literature review on knowledge of pathogens on a Scots pine (Pinus sylvestris). Three selected areas in NR Toulovcovy Maštale, represented (A) artificial and (B) natural regeneration, and (C) young growth were observed during the year 2018. In the first area, there was a place with 72 individua of which 12 were seriously damaged or killed by frying Lophodermium pinastri (Schrad.) Chevall. were observed as a saprophyte. The second area was invaded by Lophodermium pinastri as a saprophyte as well. The other pathogen was Cyclaneusma minus (Butin) DiCosmo. In the third area insect feeding was found, not resulting to death of another individua. Drought has impact to all three areasand it shows in changes in color of needles, mortality of seedling or weak individuals with insufficient root system.
