The use of authentic materials in English language lessons in Czech lower secondary school
Šišková, Veronika ; Dvořák, Bohuslav (advisor) ; Mikuláš, Martin (referee)
The diploma thesis deals with authentic materials and the use of authentic materials in English language teaching. It is divided into two main parts. The theoretical part focuses on the definitions of authentic materials and authenticity in the context of language classroom. Different views on the subject matter are compared and summarized. The link between the real- world impact and the use of authentic materials and its influence on the motivation of the pupils is briefly discussed as well. Followingly, the thesis contains a classification of the authentic materials and advantages and potential shortcomings of their use. Each material type includes a number of activities usable in English lessons. The research for the practical part was conducted at an elementary school. The practical part thus consists of two main sections, specifically designing, piloting and observing lessons where different kinds of authentic materials were employed as well as a questionnaire filled by pupils. The questionnaire inquires the learners firstly about the lessons they attended. Furthermore, it also focuses on attitudes of the pupils towards the use of authentic materials in English lessons in general, their use in pupils' free time and their preferred authentic English material kinds. The survey results are...

Identity Background
Kleinerová, Zuzana ; Kleinerová, Klára (referee) ; Klodová, Lenka (advisor)
Diploma thesis Background identity is a series of events through which I am trying to find a harmony between the magic of art and life. I decided to initiate the situation, "performance" mediating an authentic, strong feelings. I tend to performance associated with life in the self-reflective approach. Based in my own performative practice in which the strength and authenticity is reflected primarily in the exchange of energy between the audience and the performer. I started to define an ideal conditions for performance to achieve this exchange, authentic experience and mutual perception of the situation within the relationship between "performer" and "spectator". In November 2015 I planned "authentic performances " series . The mutual forming of "performing" act I have anchored in the concept of identity, which is infinitely formed in relationships and the never-ending negotiation process. In the name of authenticity I am exposing myself within the anonymity of public space and waiting for the moment of identification. Waiting for concrete spectator who is already a part of me within a certain social role. Unexpected intervention into the everyday life of concrete person make the opportunity of authentic experience. Experience which is a part of his everyday life completes the action, giving the context. During the realization I got the opportunity to exhibit in the Palais de Tokyo. Aware of the significance of this opportunity for the development of my own artistic career I have decided to accepted it as a challenge. Although the terms of institution are utter contradiction of those conditions I had defined previously for authentic experience. In the name of authenticity and my principles I decided to be present in the role of spectator. To be invisible to this prestigious gallery. Be invisible to the artistic group Delta Total through which I had the opportunity to exhibit. To be inside and outside in the same time. The starting point of the last part is a necessity with the goal to get a master's degree. The necessity of outcome for jury can also betray my ideals of living authentic event. I should mediate all the experience of past events (to date 20th of April- thirty-three events) which happened in so many different places in the space of "Malá Amerika" in Brno...

Isotopic characterization of selected fruit juices - determination of authenticity on the basis of deuterium content by SNIF-NMR
Vyčítalová, Lucie ; Kolář, Kamil (referee) ; Sečkářová,, Pavlína (advisor)
The deuterium content of sugar in fruits is influenced mainly by two factors – the botanical and also the geographical origin of the fruit. The information of the fruit origin is kept even after fermentation of the sugar, in the molecules of ethanol. The deuterium content on the methyl group of ethanol then varies depending upon the botanical origin of the fruit. SNIF-NMR (Site-specific Natural Isotope Fractionation – Nuclear Magnetic Resonance) is a specific method for determination of the deuterium isotopic ratio (D/H) in small molecules, e.g. ethanol. This isotopic technique is widely used for determination of sugar adulteration of fruit-based beverages (wines, fruit juices..). In this thesis, the authentic samples of five different fruits (apples, oranges, grapefruits, pineapples and grapes) available in the Czech market have been collected and analyzed by SNIF-NMR. The results are presented as well as the comparison to some commercially available fruit juices and nectars.

Study of geographical authenticity of moravian red wine
Bidmonová, Karolína ; Punčochářová, Lenka (referee) ; Pořízka, Jaromír (advisor)
This bachelor thesis discusses the possibility of using analytical methods to determine the elemental profile of wine and to detect phenolic substances in wine. The theoretical part describes the Czech and Moravian subregions, chemical composition of wine, authenticity and methods of assessing the authenticity of wine. The next part contains a brief description of the analytical methods that were used in the experimental part. The experimental part deals with the determination of the elemental profile of wine by mass and optical emission spectrometry, the determination of phenolic substances by high performance liquid chromatography, the determination of antioxidant activity and the total content of phenolic substances. For the purpose of classifying wine samples into groups, multidimensional statistical methods (cluster analysis, principal component analysis, analysis of variance and discriminant analysis) were used to separate the groups according to geographical origin.

Determination of honey authenticity and adulteration by anion exchange chromatography
Ždiniaková, Tereza ; Diviš, Pavel (referee) ; Vespalcová, Milena (advisor)
Cieľom tejto diplomovej práce je stanoviť kvalitu a zloženie medu, taktiež stanoviť jeho botanický pôvod na základe profilu sacharidov v mede. Med je prírodný produkt vysokej kvality a vďaka značnej spotrebe a nemalej trhovej hodnote je tiež terčom na falšovanie. S cieľom identifikovať podvody a cudzorodé látky, pochádzajúce z cukrových sirupov, boli analyzované oligosacharidy a polysacharidy na báze maltodextrínov. Teoretická časť popisuje chemické zloženie medu a hlavné princípy aplikovanej inštrumentálnej techniky. Poskytuje literárny prehľad existujúcich analytických metód na stanovenie sacharidov prítomných v mede a na odhalenie jeho falšovania. Boli definované hlavné body falšovania a autenticity, vrátane legislatívnych aspektov a opisu bežných druhov falšovania. Experimentálna časť obsahuje postupy, ktoré vedú k vývoju a optimalizácii chromatografických podmienok a parametrov elektrochemického detektora na stanovenie sacharidov a maltodextrínov (oligosacharidov a polysacharidov) vo vzorkách medu. Použitá analytická technika bola vysoko účinná aniónovo-výmenná chromatografia (HPAEC) spojená s pulzným amperometrickým detektorom (PAD). Vyvinutá a optimalizovaná chromatografická metóda bola taktiež validovaná z hľadiska linearity, dynamického rozsahu, analytických limitov, presnosti a správnosti. Na záver bola táto vypracovaná metóda úspešne zhodnotená analýzou autentických a falšovaných vzoriek medu rôzneho botanického pôvodu pochádzajúcich z členských štátov EÚ.

Application of spectral and non-spectral analytical methods for monitoring the quality of ketchups
Havlíčková, Barbora ; Vítová, Eva (referee) ; Diviš, Pavel (advisor)
The aim of the master´s thesis was to verify the applicability of elemental analysis and molecular spectrometry for examining the authenticity of ketchup. For verify of share refractometric dry matter introduced into ketchup from tomatoes was used analysis of potassium and lycopene content. Ketchups with different tomato contents were prepared and subsequently models were created, which were used to verify the proportion of refractometric dry matter introduced into tomato ketchup in ketchups from the store. The results of the work showed that the amount of lycopene is a problematic marker for verifying the authenticity of ketchup, because during the production of ketchup, lycopene is degraded.In contrast, the amount of potassium in ketchup has been shown to be a good marker for monitoring the authenticity of ketchup. The model based on the potassium content of ketchup worked reliably, the deviations obtained from the quantity of tomatoes used for the production of ketchup indicated on the packaging were less than 10%. Higher deviations were achieved in ketchups with a minimum permitted tomato content of up to 20%. The concentration of potassium in ketchup with a lower content of used tomatoes can be significantly affected by the addition of other ingredients to the ketchup (onion, garlic, carrot, apple, etc.). In addition to the ketchup production technology used, the ripeness of tomatoes also has a significant effect on the model for verifying the authenticity of ketchup.
