Cigánek, Martin ; Imramovský, Aleš (referee) ; Vyňuchal, Jan (referee) ; Krajčovič, Jozef (advisor)
Dizertační práce pojednává o studiu, syntéze a chemické derivatizaci molekul spadajících do skupiny organických vysoce výkonných pigmentů a jejich potenciálním uplatnění v oblastech organické elektroniky. Teoretická část práce je zaměřena na nejnovější trendy v dané oblasti, a to jak z aplikačního potenciálu konkrétních derivátů, tak z pohledu syntetických možností a jejich strukturálních derivatizací. V experimentální části je pak podrobně popsána příprava pestré škály intermediátů a výsledných produktů, zahrnujících deriváty diketopyrrolopyrrolů (DPP), benzodifuranonu (BDF), epindolidionu (EP), naphthyridinedionu (NTD) a polymeru na bázi thiofenu (PT). Celkově bylo nasyntetizováno 103 molekul, přičemž 49 tvořily výsledné produkty, z nichž 27 bylo zcela nových, dosud nepublikovaných. Hlavním motivem derivatizace molekul pigmentů je zde inkorporace derivátů adamantanu do finálních struktur. V další části práce jsou blíže diskutovány jednotlivé chemické modifikace vedoucí k výsledným produktům. Na sérii N,N'-; N,O'- a O,O'-substituovaných derivátů DPP je popsána komplexní studie vlivu charakteru alkylových řetězců a také pozice jejich navázání v molekule DPP, a to nejen na selektivitu reakce, ale rovněž na optické i termické vlastnosti syntetizovaných produktů.

OPtimization od cultivation od microalgae cultures in photobioreactors
Byrtusová, Dana ; Márová, Ivana (referee) ; Kočí, Radka (advisor)
Presented diploma thesis is focused on the optimisation of Haematococcus pluvialis cultivations in different photobioreactors and on biotechnological production of astaxanthin. Theoretical part summarized the knowledge about optimal growth and production conditions of secondary metabolites. Followed research was focused on actual cultivation systems and on the possibilities of metabolite and nutrient monitoring. In experimental part the growth characteristic of the strain from Březova nad Svitavou (HMP-CCALA 375) was analyzed under optimal cultivation conditions on white and red light. During culture growth the profile and the concentration of carotenoid pigments were determined. The best yield of biomass was achieved in the cultivation on white light (0,939 g/l),carotenoids lutein and -carotene were observed as dominant pigments. In the next experiments optimal growth medium, temperature and light intensity were determined for cultivations of four chosen HMP strains from Germany, America, Africa and Switzerland. The most suitable cultivation medium was found BBM, oppositely the worst results were obtained with BG11. In previous experiments cultivation temperature 22 °C was determined as optimal value for comparative strain HMP – CCALA 375. Selected four strains were cultivated at 22 °C, as well as at 25 °C. Higher temperature was more optimal mainly for Switzerland, German and Africa strains. By analyzing of light intensity influence, it was found that the best increase of biomass was induced by the adaptation of culture on lower illumination (50 µmol photones•m^-2•s^-1) followed by higher light intensity (100 - 150 µmol photones•m^-2•s^-1). HMP from Switzerland showed the best growth results during all cultivation experiments, so this strain could be perhaps useful for industrial production of astaxanthin. In the last part of work, the influence of stress conditions on astaxanthin production by strain from Březova nad Svitavou (HMP – CCALA 375) was studied. Followed stress factors were used: high intensity of light (1 000 µmol photones•m^-2•s^-1), low nitrogen concentration (32,96 mg/l), addition of sodium chloride (0,5%), influence of sodium acetate (2,2 mM) and combination of sodium chloride and sodium acetate (0,5% NaCl, 2mM NaAc). Due to strong illumination (1 000 µmol photones•m^-2•s^-1) the best yield of astaxanthin was obtained (more than 20 mg/g). According to literature [103, 105] significant amount was also observed by addition of sodium acetate (9,2 mg/g). Oppositely minimal astaxanthin production was showed in presence of salt stress (3,8 mg/g). In followed experiments should be studied the influence of stress combinations on HMP – CCALA 375 strain as well as on other suitable strains of H. pluvialis with the aim to achieve the maximal yield of astaxanthin significant for large scale cultivation.

The house for the handicapped people in the centre of town listed reservation
Konvičný, Tomáš ; Foretníková, Ladislava (referee) ; Šindlar, Jiljí (advisor)
The subject of this diploma thesis is a project of a building for handicapped people. This building is set into the historic center of the urban conservation area in Lipník nad Bečvou. The site for the building has a rectangular plan in view and is situated on the edge of the southern row of houses on the T.G.M. square and the western row of houses of Křížkovského street. The conditions for the building of the house in a view of the conservation care: - the house has maximally two floors - the plan in view must respect the street line - the roof must be inclined - wooden windows and doors - lime plaster The mass solution is based on the concept of the ending of both present street faces, whose heights are very different. The part of the building which faces towards the square, fulfils the condition of two floors building and thus in the long distance view from the square it does not eclipse the skyline of the bell tower and St. Jacob´s church. The higher part of the house follows the currently standing house in Křížkovský street, it makes a second plan impression and it does not disturb the long distance view. The southern orientation of the taller part contributes to a good sunlit of the inner space and the taller height enables a better use of the building plot. Both masses are connected by a part with the eastern orientation which is sunk in the view of the base line and so it enables to make he space for placing the ramp and two stanby parking places. The building is partly two-floored and partly four-floored with one floor in the underground. In the grand floor there is placed six parking places, technical background and storage rooms. The vertical transport is provided by both personal and freight lifts, the inner staircase a set forth ramp and one direction ramp for cars, which is controlled by trafic lights. In the first floor there are: 2 commercially useful spaces with backgrounds, a freight ramp for materials and workshop products transport and a waste storage. In the second floor there are a workshop with backgrounds (office, storage room, daily room, cloakroom and bathroom) and a flat (103 m2). In the third floor there are two flats (79 m2) and (49 m2). In the fourth floor there is a flat (79 m2). The construction of the house is monolytic, made of steel and concrete. It is made of basal belts, footing, peripheral supporting walls, bearers and ceiling boards. The dividing walls are concrete. The concrete construction is like a view from the inner space and from the other space. It is warmed with mineral fiberglass, which is covered with a retaining hydroisolation and cement facing with a lime plaster. This everything is hung on an aluminium profiles grid. In the ground floor, the fillings of the slots are aluminium eloxed in an anthracite grey colour. In the other floors They are made of wood with a wooden facing. The roof construction is made of a wooden bond which is put on a steel and concrete construction. The roof case is ventilated and there are aluminium eloxed folded templates.
