School, the Foundation of Life – a Complex of Educational Buildings in Ostrava, Cerna louka
Slavíková, Barbora ; Halfar, Jiří (referee) ; Mikulášek, David (advisor)
The location of Černá louka is situated between the city-centre of Moravská Ostrava and an area of Slezská Ostrava next to the confluence of two rivers – Ostravice and Lučina. The development at the building site of Černá louka is a result from an international competition 2010, which winner was the project Culture Meadow from studio Maxwan. The main idea of the project is to concentrate cultural and educational buildings around a culture meadow. This design has been used as a default situation for the master´s thesis. The complex of schools is situated at the parcel of existing Miniuni-site between cultural cluster Černá louka and the residential quarter Nová Karolina. The volume of the school with its front-spaces reacts to the surrounding structures. In the middle of the complex arises a half-public open space, where are located the internal entrances. Because of the placing of the school next to the city-centre the multifunctional pitch is situated on the roof of the gym. The design of the school respects principles of the age differentiation just as the horizontal integration. That´s why the substance makes up a symbiosis of 5 parts - common space, gym, first and second level, gymnasium. These parts are connected together and at the same time enable to use individual parts separately. The building of kindergarten with its garden is separated from the school because of differential needs of the smallest children.

Microstructure and properties of YSZ thermal barier coatings deposited onto CoNiCrAlY bond coats remelted by electron beam
Slavíková, Barbora ; Jan, Vít (referee) ; Dlouhý, Ivo (advisor)
The master thesis is dealing with characterization of the structure and properties of the YSZ thermal barrier coating deposited by water hybrid plasma spray technology on the CoNiCrAlY bond coats modified by using electron beam and vacuum annealing. Deposition of the bond coats was performed via high velocity oxy-fuel technology and cold spray. In case of experimental evaluation, the microstructure and chemical composition of the ceramic top coat deposited with powder and suspension feedstock was analyzed. The same analysis procedure was used also for bond coats after electron beam remelting by using two sets of parameters. Furthermore, the changes in microstructure and chemical composition of the remelted and annealed bond coats was evaluated. Eventually, the micromechanical properties of the top coats and the bond coats were measured. The ceramic top coats deposited with powder feedstock exhibited the structure composed by splats, while the top coats deposited in form of suspension showed fine structure with columnar grains. The dendritic structure was observed on remelted bond coats. The annealing process had an influence on the structure in form of coarsened phases and the chemical composition was changed due to diffusion of the elements.

Analysis of the influence of temperature cycles on the elimination of recast layer on materials used in aerospace
Slavíková, Barbora ; Martin,, Grepl (referee) ; Horník, Vít (advisor)
This bachelor thesis is dealing with the analysis of the influence of temperature cycles on the elimination of recast layer on materials used in aerospace. This thesis was created in cooperation with Honeywell Aerospace Company in Olomouc. The aim of this work was to prepare the study about influence of the brazing heat cycle on recast layer removing which was caused by laser cutting process. In first part of this bachelor thesis the unconventional machining methods, materials and related brazing processes used in Honeywell Aerospace Olomouc were described. Second part of the thesis consists of experimental measurement of the recast layer provided on a test specimens including their evaluation and interpretation of the results. The conclusions of this bachelor thesis will be used as future reference for next technological research in Honeywell Aerospace Company in Olomouc.

Analysis of novel members of FAHFA lipid class derived from omega 3-PUFA by LC-MS/MS and LC-MS/MS/MS

White adipose tissue (WAT) is a complex organ with both metabolic and endocrine functions. Dysregulation of all of these functions of WAT, together with low-grade inflammation of the tissue in obesity, contributes to the development of insulin resistance and type 2 diabetes. Omega-3 polyunsaturated fatty acids (PUFA) of marine origin play an important role in resolution of inflammation and exert beneficial metabolic effects. Using LC-MS/MS method, we elucidated the structures of novel members of fatty acid esters of hydroxy fatty acids (FAHFA), which were present in murine and human serum and WAT after omega-3 PUFA supplementation in diet. These compounds contained DHA esterified to 9- and 13-hydroxyoctadecadienoic acid (HLA) termed 9-DHAHLA and 13-DHAHLA, and were synthesized in WAT. Our results document the existence of novel lipid mediators, which are involved in the beneficial anti-inflammatory effects attributed toomega-3 PUFA, in both miceandhumans.

Vliv intravitálních vlivů na kvalitu mléka
Slavíková, Barbora
ABSTRACT This bachelor thesis describes issues of intravital effects that considerably affect production of milk in quality and quantity way. It's necessary for breeder to understand fundamental requirements and lifestyle of dairy cows. Cattle productivity and milk composition are affected by many factors, which can be divided into external and internal factors. External factors are for example nutrition and technology of breeding and milking. Internal factors are for example genetic potential, individuality of dairy cow and its health. Important part of keeping high quality is raw milk primary production. It's mandatory, in this part, to provide maximal hygiene during the breeding, milking and manipulation with raw milk. Compliance with hygienic rules affects quantity, quality, health safety and economics of production.
