Technologie výroby vína pomocí řízené a spontánní fermentace
Svobodová, Hana
This work deals with the comparison of spontaneous and controlled fermentation from the point of view of analytical and sensory evaluation. The results clearly demonstrate the potential of each method with a reflection on the concentration of some important substances that affect the wine in a positive or negative result. The literature section contains basic information on the conditions of controlled and spontaneous fermentation, including the influence of indigenous yeasts on the character of the wine. Reference is made to the noble yeasts Saccharomyces cerevisiae and Saccharomyces bayanus and their positive effect on wine. Furthermore, the work contains important parameters affecting the course of the whole fermentation process. The practical part of the thesis contains basic data on the processing of grapes to the pressed juice, subsequent racking and the beginnings of spontaneous and controlled fermentation. Although there were minor complications during the maturation of the wine on the lees, the resulting wine was examined in the laboratory, the values of significant substances were determined and these were compared in the context of spontaneous and controlled fermentation. In the same way, a sensory evaluation of the wines was carried out, detailing the structure and robustness of the wine and its aromatic potential.

Monitoring vodního toku Bobrůvka
Svobodová, Helena
This bachelor's work occupies with a monitoring of the river called "Bobrůvka". The river was monitored since the stream to the confluence with Svratka 63 km in length. The first part of the work processed the literary summary with the characteristic of the area and the mentioned flow itself. Here the work devotes to themes as water, the quality of water and the pollution of water. The literary search also engages of monitoring of the quality of water. In the next part of the work there is a description of the methodology of the work in a terrain and in a laboratory. The chapter "Results" catchs the acquired and processed values, which are commented in a part called "Discussion". During a monitoring of the stream in terrain were the water samples taken away and these indicators were found out: pH, temperature, conductivity, run oxygen. Following parametres were determined by analysis in laboratory: mangan, sulphates, nitrite's nitrogen, nitrate's nitrogen, chlorids, orthophosphates and the chemical cunsumption of oxygen. The reults were evaluated and compared with ČSN 75 7221 and with the provision of government n. 61/2003 in an effective version.

The expression of the accuracy of the gauge and measurement
Svobodová, Helena ; Koška, Petr (referee) ; Pernikář, Jiří (advisor)
The bachelor thesis deals with the issue of measurement, accuracy of measuring instruments and their expressing. It outlines the legislative basis of metrology in the Czech Republic and interprets the definitions of basic terms used in metrology. These definitions are listed in the new edition of International dictionary of metrology (VIM 3:2007). It specifies and exemplifies measurement errors and presents possibilities of their elimination. Further, it describes a simple way of measurement uncertainty determination. The aim of this thesis is to explain the issue in a way that it is understandable and can be applicable for the common metrology practice.

The Case
Svobodová, Hana ; Šrek Bromová, Veronika (referee) ; Gabriel, Michal (advisor)
I assume huddled topic that I put into my past work as well as in final work. Casting my body, which is covered with feathers and create a cocoon of him, husk without the interior. Sculpture has two sides, the principle of duality, femininity and counterpart. Outer packaging evokes pleasant birdlike body surface and in the inner part aggressively squeeze ends of the wicks feathers.
