Temporary dwelling of migrants-reception and residential center
Vondráková, Kateřina ; Dvořák, Miloš (referee) ; Nový, Alois (advisor)
The theme of diploma thesis is design of reception center and residential center in Brno city. These asylum facilities are first two steps to proceeding for granting international protection. Both of these facilities provide accomodation and other services, such as provide of meals, social and psychological services, legal help or clients can take part in wide range of free-time activites. Designed complex is located at Červený kopec in Brno-Štýřice and it consists of 6 building divided into three parts - reception center, residential center and central structures used by the both facilities, such as administration, kitchen and maintenance services.

Temporary dwelling of migrants-reception and residential center
Bosák, Martin ; Dvořák, Miloš (referee) ; Nový, Alois (advisor)
The content of the thesis is an architectural study of the temporary accommodation of migrants and finding a suitable location on the territory of the city of Brno. The choice of land suitable for construction must meet not only the technical requirements but also take into account the sensitive public relation to this type of equipment. The location of the Malměřice-Obřany district in Brno, currently managed as a brownfield, meets all the requirements and contributes to the reclamation of urban space.

Study on pretreatment and hydrolysis of selected lignocellulose materials
Kovářová, Markéta ; Dvořák, Miloš (referee) ; Obruča, Stanislav (advisor)
This diploma thesis is focused on study of chemical and enzymatical hydrolysis of raw wood material. The aim of this work was to find the suitable method for pretreatment of selected lignocellulose materials. The theoretical part deals with characterization of lignocellulosic material and its components. There are also subscribed various pretreatment methods and their effect on hydrolysis of sawdust. In experimental part of the work the most appropriate approach of pretreatment and hydrolysis of sawdust was studied. Criteria for the selection of suitable method was concentration of saccharides as desired product of hydrolysis and also concentration of the most important microbial inhibitors - polyphenols. Application of 96% ethanol or 5% H2O2 were identified as the most promising pretreatment methods which enhanced yields of fermentable sugars about 30 %. Further, we also performed cultivation of bacteria Burkholderia cepacia and bacteria Burkholderia sacchari using solution obtained by hydrolysis of lignocellulose material.

Portable and Miniaturized Separation Techniques Applicable for Food and Biotechnology Analysis
Dvořák, Miloš ; Pospíchal, Jan (referee) ; Bednář,, Petr (referee) ; Rittich, Bohuslav (advisor)
Capillary electrophoresis was used for determination of 6 fractions of caseins. Those fractions were measured in 144 samples of cow’s milk originated from the feeding experiment focused on explanation the influence of the feeding onto casein productions. In this work were separated 6 fraction of caseins first time with total resolution of the peaks. Capillary electrophoresis was applied for determination of short-chain organic acids during fermentation of wine must. It was compared the fermentation of must fermented by different yeast. The difference of profile short-chain organic acids during fermentation were not statistically significant. The once difference was in the utilisation of the malic acid and production of the lactic acid. A portable miniaturized system for medium pressure liquid chromatography was developed. The components were tested and system was used for the isocratic and gradient elution of various analytes (food dyes, parabens). New line of electroluminescent diodes (LEDs) for deep-UV areas of wavelength based on a different materials substrate was characterised. The new line was compared with old line LEDs. The new line LEDs was incorporated in deep-UV absorbance detectors. Detectors were characterised and tested for a detection various analytes in modes flow injection analysis and chromatography separation. First time was characterised this new line of the LEDs and the origin of the parasitic emission band produced by deep-UV LEDs light sources was explained. This origin is given by disturbances of a materials substrates. This work is a contribution for an advance of low-cost and portable systems and detection devices in the field of analytical chemistry.

Evaluation of applicability of indirect photometric detection for chiral separations of selected carboxylic acids in dairy products
Dvořák, Miloš ; Zemanová, Jana (referee) ; Vespalcová, Milena (advisor)
In this diploma work is check possibility application indirect photometric detection for enantiomers separation lactic acids and beta-hydroxybutyric acid with capillary electrophoresis. As chiral selector is used vankomycin. Verifyed his ability partial separation lactic acid on antipode with using picric acid as vizualition anion in background electrolyte. Used was coated capillary. Application indirect photometric detection succeed. Chiral separation beta-hydroxybutyric acid wasn't successful. Hip roll by selection fit vizualization anions for purposes indirect photometric detection. Are measured their electrophoretic and spectrophotometric characteristics, for inquest compatibility use in capillary electrophoresis in relation to indirect photometric detection. From timed datums were to be you - nap optimal vizualizatin anions for others experimentation. According to ascertained and measured feature reflect be optimal eosine soluble in alcohol and bromophenol blue.

Probiotics and probiotic microorganisms
Kostková, Lucie ; Dvořák, Miloš (referee) ; Babák, Libor (advisor)
Probiotics and their positive influence on human health are presently very discussed theme. Nevertheless is informedness of public about probiotics benign influence insufficient, as well as their practical usage. This thesis summarizes present scientific knowledge about probiotic effects on human organismus. Fisrt chapter deals with determination of concept probiotics, their history, meaning, qualities, effects on human health and hazard connected with probiotic usage. Second chapter includes description of probiotic products, their forms and foodstuff containing probiotics. Chapter three discuss probiotic microorganisms, their main characteristics and examples of commercial starting cultures. Fourth chapter takes in informations about viability of probiotic microorganisms. And last chapter researches methods of integration of probiotics into products.

The content of allergenic aromatic compounds in chosen food types
Fidrichová, Ivana ; Dvořák, Miloš (referee) ; Vítová, Eva (advisor)
This thesis describes properties, origin, usage and methods of obtaining fragrances of vegetable origin, which are common part of food products. Although the aroma substances are not classified as the main group of allergens, in many cases there is a warning of their allergic potential. 26 crucial fragrance allergens and related restrictions are set by the European Cosmetic Regulations. There is no coincident regulation for food processing industry so far. The practical part dealt with identification of potential allergenic fragrances in randomly selected food products.
