Process Optimization Project to implement an Integrated Management System
Moravcová, Gabriela ; Milichovský, Miloš (referee) ; Videcká, Zdeňka (advisor)
First part is an introduction into this thema, followed with second part, which clarifies (describes) the whole process from receiving the demand through part development till serial production approval. Third part describes the claim procedure, including all methods, used for solving the problems and followed with short analyse of production centres activities and sorting the claims by causer. All claims are given factors, which may cause claim occurence. Every factor is given by specific importance (weight) and the achieved data are evaluated. In final part I suggest the corrective actions.

Effects of nitrogen supply and drought on wheat grain quality under the ambient and elevated concentrations of carbon dioxide
Moravcová, Gabriela ; Vránová, Dana (referee) ; Hrstka, Miroslav (advisor)
This diploma thesis deals with effects of nitrogen supply, drought and UV radiation on wheat grain quality under the ambient and elevated concentrations of carbon dioxide. The theoretical part deals with the global climate changes, greenhouse gases and especially with effects of elevated concentrations of carbon dioxide on plants. Also, it is dealt with effects of elevated concentrations of carbon dioxide on the wheat grain quality. In the experimental part nitrogen content by the Kjeldahl method, contents of dry and wet gluten, Zeleny test, falling number and content of starch in the wheat samples were determined. The results of this study confirmed affecting the quality of the wheat grain from the elevated concentrations of CO2, nitrogen fertilization, drought and UV radiation. The most evident was the influence of nitrogen nutrition, fertilization positively affected the quality of grain, there was an increase in content of crude protein, gluten content, value of Zeleny sedimentation test, and falling number. As a result of the increase in protein content was also a decrease in starch content. Due to increased levels of carbon dioxide protein content and gluten, Zeleny sedimentation test values and falling number decreased and conversely starch content increased. The decrease of Zeleny sedimentation test by the influence of elevated CO2 concentration was fully compensated by nitrogen fertilization.

Spectrophotometric determination of ascorbic acid in coloured samples
Moravcová, Gabriela ; Vespalcová, Milena (referee) ; Hrstka, Miroslav (advisor)
This bachelor’s thesis deals with spectrophotometric determination of ascorbic acid after the xylen extraction in coloured samples. The theoretical part deals with reactions, biochemistry and occurrence of ascorbic acid in foodstuffs. Also, it is dealt with various methods of determination of ascorbic acid, such as HPLC methods, electrochemical methods, titrimetric determinations, spectrophotometric determinations or polarographic method. In the experimental part of this method were first determined the concentration of ascorbic acid in the standards, then in real samples (vitamin tablets, orange juice and the juice of cultivated varieties of elderberry). Some validation parameters of the method were also determined. Sensitivity of the method was determined to 1,6772, linearity to 0,9990, limit of detection was set at 0,0466 mg/ml and the detection limit at 0,1552 mg/ml. Accuracy of the method was expressed as relative standard deviation, which gained 3,00% in value.

Digital communication of the Czech olympic team at The 2018 Winter Olympics
Moravcová, Gabriela ; Halada, Jan (advisor) ; Turková, Kateřina (referee)
This diploma thesis named Digital Communication of the Czech Olympic Team at the 2018 Winter Olympics deals with the communication of the Czech Olympic Committee, focusing on social media profiles - the Czech Olympic Team, which the Czech Olympic Committee manages and communicates through them to the target audience. The diploma thesis analyzes communication specifically during the XXIII. Winter Olympic Games in PyeongChang, South Korea and focuses on communication on Instagram and YouTube. The theoretical part outlines the history of the Olympic Games, explains the basic concepts of marketing and PR and the connection of these disciplines to sports and social networks. The analytical part explains the functioning of the Czech Olympic Committee and analyzes the communication on Instagram and YouTube during the Olympics. The analysis was partly based on data from the Czech Olympic production and partly my own research and analysis of posts from the period under review. To the analysis are added findings from a structured interview with the head of digital communication and is followed up with recommendations for future communication of this association.

Minerální látky a vitaminy v kozím mléce
Moravcová, Gabriela
My Bachelor's composition is related to Mineral substances and vitamins contained in goat's milk. I'm evaluating goat farming situation not only in the Czech Republic, but also in Europe and worldwide based on available literary sources. Sources of individual vitamins and mineral substances in other food, their daily recommended allowances and their importance for human being are described in there. Bachelor's composition is aiming to familiarize readers with ingredient proportional representation issues in goat's milk depending on several factors, whose contains may vary. Vitamin B12 is representing the smallest amount, the other way around niacin and vitamin B6 concentration represents the highest amount in goat's milk. From the point of view of Mineral substances, goat's milk is rich in Calcium and Potassium and low in Jodine and Selenium concentration.
