Investigation of calibration factor stability for GC-FID analysis of alcoholic products quality by internal standard methods
Čermáková, Veronika ; Čabala, Radomír (advisor) ; Coufal, Pavel (referee)
This thesis focuses on measuring calibration factors and the dependence of their stability on experimental conditions for the purpose of quality control and the safety of alcoholic beverages using gas chromatography with flame ionization detection (GC-FID). Ten volatile compounds (acetaldehyde, methanol, methyl acetate, ethyl acetate, 1-propanol, 1-butanol, 2-butanol, isobutanol, acetal, 3-methyl-1-butanol) were monitored according to the legal regulations of the European Commission. These target compounds were analysed in prepared solutions under 27 different measurement conditions. Taguchi's multifactorial statistical method was used to determine the influence of individual measurement parameters on the stability of calibration factors. The chosen variables for measurements were matrix composition, concentration of volatile compounds, GC injector temperature, sample injection volume, injection split ratio, and detector temperature. Within the experiments, each of these variable factors took one of three possible values. Relative response factors (RRF) for each analysed compound were compared using two internal standard (IS) methods. One method utilised commonly used 1-pentanol as the internal standard, while in the other, ethanol, the main component of all alcoholic beverages, was used as the...

Processing of territorial study as a basis for urban plan
ČERMÁKOVÁ, Veronika
The diploma thesis is focused on the preparation of a territorial study and the related issues of territorial planning. The chosen locality for the development of the study is the village of Myslkovice. Through the analysis, several problems were found to be solved. This is a lack of living space, a threat to the popular public space in front of the local castle and noise and dust pollution around the production areas. Each of the locations requires a different solution and all are described in detail in this thesis. In addition to the solution and description of the affected areas, the work also inc-ludes a literature search of the chosen issue and a detailed description of the area. The conclusion of the work is the recommendation of resulting strategies to improve the analyzed problems.

Vliv drenážních systémů na odtokové charakteristiky vybraného povodí
ČERMÁKOVÁ, Veronika
This bachelor thesis deals with drainage, especially drainage by drainage systems and their impact on various aspects of nature. The introductory part explains what drainage systems are, what they are used for and what they look like. Furthermore, the history and occurrence of drainage systems in the world and also in the Czech Republic are described. Subsequently, several chapters are devoted to methods of drainage and then a description of drainage systems. The following are the impacts of drainage systems on the water regime of the river basin and on the environment. After processing and analyzing data on runoff and precipitation conditions to a selected catchment area of the Jenínský stream, their behavior during the hydrological years 1984-1985, 2005-2007 and 2011-2013 was compared. In these years, the runoff coefficient was calculated, and subsequently double sum lines were constructed, which show the purpose of identifying changes in the long-term balance of precipitation and runoff.

Formulation of biodegradable nanoparticles containing terbinafine
Čermáková, Věra ; Dittrich, Milan (advisor) ; Šnejdrová, Eva (referee)
ABSTRAKT- EN The aim of the thesis was targeted towards the assimilation of preparation method of nanoparticulate systems from biodegradable aliphatic polyester carriers. The procedure based on dispersion and homogenisation of carrier solutions in chlorinated hydrocarbons in aqueous phase was proven. Gelatin hydrolysate and blend of lecithine with plolysorbate were used as komplex emulsifiers. The prepared samples were measured from the aspect of their size and zeta potential values. Reverse dialysis as novel púroposed method of nanosuspensions concentration and following spray drying with manitol carrier were tested by IA method.
