This master thesis continues the master thesis Výroba vodíku z biomasy. In that work were performed first experiments of hydrogen production from beer less by dark fermentation. Further experiments will continue based on previous experiments. For the energy balance were used results from [1] and data obtained from literature searches, because the results of the experiments were not entirely satisfactory. Energy balance was calculated for a laboratory fermenter to evaluate the efficiency of energy obtainable from the hydrogen produced by fermentation in a dark laboratory conditions. It was compared the yield given in [1] and yield derived from a literature review. The conclusion presents recommendations for further research.

The presented thesis deals with the issue of mycotoxins in brewing materials and beer. Attention was devoted mainly to the selected fusarium mycotoxins (deoxynivalenol, zearalenol, T-2 toxin, and HT-2 toxin) ochratoxin A and aflatoxins B1, B2, G1, and G2. The aim of the thesis was to optimize and validate analytical methods for the determination of the above mentioned mycotoxins in the brewing materials and beer. Analytes were separated using high-performance liquid chromatography with mass – spectrometric detection (HPLC-MS/MS) and ultra-performance liquid chromatography with fluorescence detection (UPLC/FLR). These analytical methods were then applied for mapping the occurrence of fusarium mycotoxins in malting barley crops in the Czech Republic and monitoring the level of contamination with mycotoxins in malting and brewing industries. In addition, experiments studying over-foaming of beer were conducted as primary gushing – over-foaming of beer – is connected, similarly as mycotoxins, with the presence of microscopic filamentous fungi in the raw materials for beer production. Studies describing in detail these methods are part of this thesis (Annex I – V). From all published results, it is evident that the occurrence of mycotoxins in cereals including barley is natural and cannot be completely prevented, not even if all conditions of correct agricultural practice are observed. It is known that some mycotoxins present in contaminated malting barley pass to the final product – beer due to their chemical and physical properties. However, the mycotoxin concentrations found do not mean any significant health risk for consumers.

The thesis has focused on the separation of proanthocyanidins (Pas) in beer, raw beer material and beer intermediates (wort, hopped wort, green beer) by using high performance liquid chromatography coupled to high resolution mass spectrometric detection. A chromatographic column XSELECT HSS T3 was used for separation of individual proanthocyanidins. Mobile phase was formed by a mixture of 0,1% formic acid in water (A) and 0,1% formic acid in acetonitril (B), separation was conducted in gradient mode. Calibration range for catechin and procyanidin B1 a B2 was linear in the range from 10 µg.l-1 to 200 µg.l-1 and for epicatechin from 5 µg.l-1 to 200 µg.l-1 . Limit of quantitation (LOQ) was set to the lowest point of calibration curve, hence for catechin, procyanidin B1 and B2 was LOQ = 10 µg.l-1 and for epicatechin was LOQ = µg.l-1 . Yield of method of the observed Pas was very good, where yield oscillated around 100%. The method also had excellent repeatability, where the relative standard deviation (RSD) was lower then 20%. After optimization of this method it was used for observation of profile changes during brewery process in catechin, epicatechin, procyanidin B1, B2 and B3. It was discovered, that catechin, epicatechin, procyanidin B1 and B2 originate mainly from hops and procyaniding B3 is...

In this thesis the optical changes of beers and model beer solutions during their photodegradation were studied. The optical changes - change of absorbance - were measured on the prototype of apparatus COLORTURB and were correlated with sensory tested intensity of the lightstruck flavour of beer and with riboflavin content in samples. High correlation between the lightstruck flavour intensity, the loss of absorbance at the wavelength of 450 nm and the riboflavin content loss was found. The partial recovery of the absorbance for both beers and model beer solutions was found and was attributed to the riboflavin photoproducts transformation. Powered by TCPDF (www.tcpdf.org)

Master thesis Hitler's Beer Hall Putsch in 1923 in the Czech period press focuses on the reception of the Hitler's putch atempt on 9th and 10th of November 1923 in czech and slovak written political press of the 1920's. The preliminary part of the thesis is dedicated to the political and the economical developmnet in the postwar Germany between 1918 and 1923. The following two chapters are dedicated to the Hitler's youth and early polical career and the München putsch. The second half of the thesis evaluate the reaction of the press to the Hitler's putch. It focuses on to the reaction of legitimate bavarian goveremnt and the legitimate german goverment. The press also follows the overlapt of the Münich revolution ant its suppor between some of German nationals in Czechoslovakia. In the analysis will be used daily party's newspapers as well as small regional newspapers. Keywords Adolf Hitler, Beer Hall Putsch, Germany, 1923, Czechoslovakia

El objetivo de la presente investigación es determinar la relación entre las variables marketing experiencial y la recompra de cervezas artesanales en los bares por parte de hombres y mujeres entre los 20 a 35 años. De esta manera, poder identificar qué variable tiene mayor correlación con la intención de compra. Esta investigación es de alcance correlacional, ya que busca describir y relacionar los motivos de intención de compra en base a las variables y dimensiones puestas en estudio. Asimismo, se decidió investigar antecedentes, entrevistar a tres expertos en el rubro y realizar dos focus group con el público objetivo. Se halló que las variables y dimensiones de mayor relación con la recompra son la experiencia, el producto, los precios y estilo de vida. Por último, a partir de la investigación, se ha conocido de forma más profunda al público objetivo. Los resultados con mayor relevancia son que el marketing experiencial junto a las acciones de actuaciones, son fundamentales para que el target recompre cervezas artesanales en los bares y que definitivamente, el precio influye en la decisión de compra. / The objective of this research is to determine the relationship between the variables experiential marketing and the repurchase of craft beers in breweries by men and women between the ages of 20 and 35. In this way, to identify which variable has the greatest correlation with the purchase intention. This research is based on a scope of correlational, since it seeks to describe and relate the reasons for purchase intention based on the variables and dimensions put into study. Likewise, it was decided to investigate the background, interviewed three experts in the field and conducted two focus groups with the target audience.
