Acidic Hydrolysis of Waste Feather Biomass - Processes Scale-Up.
Hanika, Jiří ; Rousková, Milena ; Šolcová, Olga ; Šabata, Stanislav ; Jírů, M. ; Hůrková, K.
The paper present novel data on acidic hydrolysis of waste chicken feathersin presence of water solution containing carboxylic acid catalyst with the pKa value lower than 4, instirred batch reactors, in the temperature range from 114°Cto 150°C and at the pertinent vapour pressure of reaction mixture.The process was scaled-up from laboratory bench scale to pilot plant dimensions using batch high pressure autoclaves. Process conditions were applied according to patent application1. Knowledge of kinetic aspects of the featherhydrolysis and process parameters operation window are inevitable for asuccessful process scale up2,3.

Simultaneous Hydrolysis of Proteins and Fats fro Waste Chicken Feathers.
Rousková, Milena ; Šolcová, Olga ; Šabata, Stanislav ; Jírů, M. ; Hůrková, K. ; Hanika, Jiří
The kinetics of the simultaneous hydrolysis of macromolecular proteins (keratin) and lipids (fat) from waste chicken feathers was investigated in this study. The perspective option pressure hydrolysis at elevated temperature was designed as one of the primary tasks within the research program in frame of the Competence Centre BIORAF, supported by the Technology Agency of the CR. The process development of simultaneous hydrolysis of proteins and lipids contained in the waste is focused on this potential alternative raw material for the preparation of valuable amino acids1 and proteins of low molecular weight. In this study, the acidic hydrolysis kinetics of the waste biomass was performed using a batch stirred bench scale autoclave at elevated temperature and pressure of inert atmosphere from 0.9 to 2.3 MPa. Produced hydrolysate was filtrated and subsequently analyzed using HPLC/MS method at the UCT Prague.

Extraction of Antioxidants from Fresh Wine Grapes Marc.
Rousková, Milena ; Jírů, M. ; Krmela, A. ; Hanika, Jiří ; Šolcová, Olga
The study is focused on concentration of a lipid content and determination of the extractable part oriented on included fatty acids in separated phases of centrifuged wet biomass. The main attention was focused on the DHA concentration from the upper lipid layer, containing obviously concentrated proportion of fatty acids. Water fungi suspension was submitted to centrifugation with subsequent separation of individual liquid/solid fractions and extracted by two solvent systems. Dichloromethane/methanol 1/1 and 1-hexane/ethanol 2/3 was applied. Both solvent systems afforded comparable fatty acids profiles. Dominant acids C16:0 (in the range of 43-47%) and DHA C22:6n3 (43-47%) were detected. Biomass residue can be applied e. g. as an animal food supplement due to high protein content. Also level of pigments with antioxidant effect, particularly carotenoids, can be dietary significant.

Knowledge management, self-learning organisation and educating company
Jírů, Marie ; Hálek, Vítězslav (referee) ; Mužík, Jaroslav (referee)
The work consists of five chapters, three of them focus on theoretical basis about knowledge management, learning organisation and strategic human resource management. The fourth chapter deals with managing and transformation procesess being in education enterprises. The last chapter focuses on marketing in development of futher education. The nature of market relations in the field of education creates presuppositions and preconditions under which marketing is exerted in this field.

The effect of Spinalstabilization method according to the 1A course for changing defective deportment of 10 to 15 years old children
JÍRŮ, Markéta
This bachelor thesis is focused on poor body posture among children between the age of 10 and 15 and possibility to influence this instability with the help of Spiral stabilization method according to 1A course. This is a stabilization exercises of muscle spiral chains with elastic cords. Poor posture problems arise on the basis of imbalance between muscle groups. In case of children today, this is caused mostly due to lack of physical activities and too much time spent by sitting at televisions or computers. It is the lack of physical activity which leads to atrophy of muscles which are important for correct body posture. Another risk factors which cause poor body posture are wrong stereotyp movements, overloading muscle groups, long standing, incorrect sitting, taking an unnatural position for too long, wrong furniture (wrong chair, mattress etc.), unilaterally focused movement activities etc. Even wrong regimen can influence the emergence of poor posture. For example lack of sleep or bad eating habbits which can cause obesity. Spine, shoulder girdle and lower limps anatomy and kinesiology is desctribed in theoretical part. In the next part, muscle imbalance concept, poor body posture and posture term in general are explained. The third chapter is specifically focused on Spiral stabilization method, on its general regularities, principles, main spiral strings etc. The last section of theoretical part belongs to other methods which can be also applied during poor body posture treatment. The first goal of the work was to map physiotherapy options among children between the age of 10 and 15. The second goal was to find out if and what influence the regular exercising using Spiral stabilization method according to 1A course would have among these children. For the practical part, quality research method was chosen. Data were collected along with anamnesis from both parents and children by interview. Furthermore, initial and exit kinesiological examinations were carried out. Respondent´s parents were also asked for filling in informed consent. The bachelor thesis can be used for both professional and general public as informative and educational material about poor body posture and Spiral stabilization of the spine and its practical use.

Possibilities of image comparison in mobile applications
Jírů, Michaela ; Pavlíčková, Jarmila (advisor) ; Šedivá, Zuzana (referee)
This thesis is about methods of image comparison. Goal is to create a mobile app that allows user to compare images in real time. In the first part there is a theoretical basis, in particular image similarity algorithms. The practical part contains the app implementation including use case analysis, user interface design and functional requirements. It is followed by source code samples a description of frameworks used. Last part is made of testing the implemented algorithms regarding speed and precision.
