Factors influencing the quality of red wine
Zechmeisterová, Lucie ; Vránová, Dana (referee) ; Omelková, Jiřina (advisor)
In my thesis, I focused on monitoring of microorganisms in the sample of red grape juice and on the interactions between yeasts, bacteria and filamentous fungi. Three different media were applied for the cultivation of microorganisms; firstly for monitoring of total volume of microorganisms, secondly for yeasts and third time for lactic acid bacteria. The indirect method was used for the determination of the amount of viable cells. This method consists in enumerating of visible macroscopic colonies grown up on agar plates. When the cells grew up, the forms of colonies were analyzed visually and the morphology of microorganisms was detected microscopically. The operating time of enzymes in grape juice in the production of red wine was monitored after application of commercial enzymatic preparation. The enzym action in grape juice was observed on the basis of the process of degradation of high – molecular substrate by enzymes through the use of Ubbelohd´s viscometer. The research findings provided a lot of knowledge about the occurance of microflora in the process of production of red wine. The commercial preparations added to grape juice played a significant role.

Small Electrical Machines Optimization
Koutný, Ondřej ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Elektrické stroje se používají v mnoha oblastech života spo¬lečnosti a vyrábí se ve velkém množství a sortimentu. Jedním z nejvíce používaných druhů jsou elektrické stroje malého výkonu na malé a nízké napětí. V širším smyslu názvem malé elektrické stroje označujeme takové stroje, které mají výkon menší než 1 kW (1000 W). Z hlediska užití můžeme rozdělit malé elektrické stroje na stroje pro obecnou potřebu a pro automatizační zařízení. Jedním z nejvíce frekventovaných druhů malých elektrických strojů jsou elektrické stroje na malé napětí, t.zn. na jmenovité napětí do 50 V.

Planning and Management of Metalworking in a Business Corporation
NEPIVODOVÁ, Lenka
The main object of this work is to elaborate a production and financial plan. This plan focuses on metalworking in a business corporation. All of this is created with re-gard to supply-demand relationships linked to production and its economy. On the basis of professional literature, materials corresponding to the subject are used in the work. These are mainly literature on production, production process, production management, production planning, etc.

Planning and managing of production in small and medium sized enterprises
DRNOVÁ, Markéta
The name of this bachelor work is "Planning and managing of production in small and medium sized enterprises". This work deals analysis of planning and managing of production in the two factories with proposal to improve their process of production. Theoretical concepts on these issues are summarize in the review of literature. The practical part of this work deals about production, process of production, products and processing of requisition. Part of CENTES factory complements list of daily work activity of one employee, summary list of daily work activity and work list of product. From identified facts in factory Moravia Lacto were designed solution in area of propagation and advertising. It was recommended to expansion of the range in milk products for children and establishment the new sales place in centre of Jihlava. In factory of CENTES was designed appropriate solutions for inconvenient storage place and recommendation for improve working condition and motivation of employees. The bachelor work can bring a new feedbacks and suggestions to improve production in these factories.
