Study of geographical authenticity of Moravian white wines
Horáková, Kristýna ; Křikala, Jakub (referee) ; Diviš, Pavel (advisor)
The aim of this bachelor thesis was to verify geographical autenticity of Moravian white wines based on elemental analysis. This data were completed with the analysis of organic acids, fenolic compounds and atioxidants in wines. There were used two spektrometric methods for the elemental analysis (ICP-MS and ICP-OES). The concentration of organic acids was mesured by Ion chromatography. To determine the concentration of phenolic compounds in wines there was used the high performance liquid chromatography (HPLC-DAD), the content of antioxidants and the total content of phenols was measured on spectrophotometer. In total there were 33 samples of wine from 4 Moravian subregions. For the purpose of determination the samples in groups the dataset was firstly corrected by Grubbs test for remote results. From those data the box plots were created which represents the minimal, maximal and mean concentrations of each measured component. Furthermore the analysis of variance was applied, which picked up 12 statisticly valuable parameters from the whole 47. By appliyng the multidimensional statistical methods (Pearson correlation analysis (PCA) and discriminant analysis (DA)) were compiled mathematical models for the division of Moravian wines according to geographical origin. The success rate of the discrimination test was 96,97%. The cross-validation test showed an 81,82% success rate for classifying unknown samples.

Analysis of substances potentially dangerous to humans found in lipsticks
Horáková, Kristýna ; Kučerová, Simona (referee) ; Diviš, Pavel (advisor)
The diploma thesis deals with the determination of the content of risk elements and parabens in lipsticks and the assessment of possible negative effects on human health associated with the use of lipsticks. Parabens were analyzed by high performance liquid chromatography with diode array detection (HPLC-DAD). Aluminum, cadmium and lead were analyzed on an inductively coupled plasma mass spectrometer (ICP-MS). The mercury content was determined using an atomic absorption spectrometer with an UV detector (AAS-UV). A total of 36 lipstick samples from 22 cosmetic brands were selected for analysis, with a savings price in the range of CZK 50–1500. Based on the measured metal concentrations, the hazard quotients (HQ) for individual metals as well as the total hazard index (HI) for the sum of all metals were calculated. Metal concentrations in lipsticks were further processed using Kruskall-Wallis Anova to divide samples according to price categories. The relationship between the content of individual metals and the purchase price has not been proven. Furthermore, a Kolmogór-Smirnov test was performed on these data to compare groups with vegan and not vegan composition. The content of aluminum, which was about 2.5 times lower in vegan cosmetics, proved to be statistically significant for this distribution. Parabens were detected in the minimum number of lipsticks examined, but in some cases information on the content of parabens was missing on the product packaging.

Construction Order Preparation and Management
Horáková, Kateřina ; Jeřábek, Petr (referee) ; Waldhans, Miloš (advisor)
This thesis explains a theme of construction order preparation and management. The theoretical section describes common definition the term of project and then this section explains process of the project management. This is followed by a practical section where a construction company is introduced, this construction company provided a particular contruction order. This construction order is valued, then its processed an organizational structure, costs plan, time schedule and site accommodation for this construction order. The last part is the evaluation of the results and comparing with the results of construction company.

Natural alternatives to commonly used cosmetic bases
Horáková, Karolína ; Doležalová Weissmannová, Helena (referee) ; Zemanová, Jana (advisor)
This bachelor in terms of literature review thesis deals with cosmetic vehicles, certification of natural cosmetics and stability of cosmetic products. The aim of the experimental part is to evaluate if cosmetic product SOFTIGEN®PURA consisting of a mixture of triglycerides would be a good alternative to common Vaseline. Theoretical part describes selected groups of cosmetic vehicles, their properties and examples of use. Next the requirements that a cosmetic product must meet in order to receive the COSMOS, Ecocert or CPK certificate are briefly described. The last part of the theoretical part describes the conditions for conducting stability studies and methods by which stability can be monitored. In the experimental part, the stability of SOFTIGEN®PURA under different temperature conditions is monitored using fat characteristics and sensory analysis. The results of a comparison of the sensory properties of SOFTIGEN®PURA and common Vaseline are also presented. The results show that SOFTIGEN®PURA shows similar stability as Vaseline and similar sensory properties and can be recommended as a possible natural alternative to conventional Vaseline.

Lyophilized fruits - chemical properties and processing possibilities
Horáková, Klára ; Vítová, Eva (referee) ; Vespalcová, Milena (advisor)
This diploma thesis deals with chemical analysis of selected frozen, dried and lyophilized fruit, specifically Mirabelle de Nancy, Aronia Nero and blackcurrant varieties Gairn Ben and Ben Lomond. In the theoretical part taxonomy and botanical characteristics of selected fruit are given. Subsequently the utilization of fruit in food industry is described. In common the theoretical part focuses on lyophilisation and drying of fruit and raw food. Further in this part the methods of phenolic substances, anthocyanins, antioxidant capacity and finally ascorbic acid and carbohydrates value measurements are specified. In the experimental part the value were determined measurements of biologically active substances: total phenols, total anthocyanins, antioxidant capacity, ascorbic acid and carbohydrates. For all value measurements were compared the frozen, dried and lyophilised samples of every single fruit. Further, the every sort of fruit were compared to each other. Following the raw food preparaon a product of lyophilised fruit was made.
