Characterization of proteins, soluble gums and phenolic compounds isolated from flaxseed (Linum usitatissimum L.)
JAROŠOVÁ, Markéta
Flax (Linum usitatissimum L.) is one of the oldest domesticated crops. Its cultivation for fibre, oil or medicinal purposes was already widespread in ancient times. Nowadays, the growing of flax for the production of high-quality flaxseed oil prevails compared to fibres. However, using flaxseed as a functional food in the food industry and dietary applications has become more popular recently. Flaxseed contains bioactive components, including polyunsaturated fatty acids representing the major proportion of flaxseed oil, as well as functional proteins and peptides, lignans and dietary fibre in the forms of soluble mucilaginous polysaccharides and insoluble lignocellulose. This dissertation presents the results focused on characterisation of three significant constituents of flaxseed - proteins, polysaccharides and lignans. These groups of compounds exhibit interesting functional properties and biological activities that may be useful in a wide range of food or medical applications. This work highlights the importance and potential use of flaxseed oil cake, which is an important source of these components. In addition to the results, this thesis also provides a comprehensive literature review of previous and current research on flaxseed proteins, mucilages and lignans. The results of this work can be primarily applied to breeding new oilseed flax cultivars or in the food and processing industries. However, due to the important nutritional aspects and biological activities of the mentioned components, the obtained findings can also be used in dietary applications and medicine. In general, this work aims to expands the spectrum of knowledge on the subject and to open up the scope for further research. Two review articles represent the first part of the results. The first publication focused on the hydrocolloids of flaxseed in the form of flaxseed mucilage representing 4-15% of the flaxseed content and protein representing 20% of its weight. In this manuscript, the structure, extraction methods, functional and biological properties and possible applications of both types of hydrocolloids for the fortification of various foods or other food applications are described in detail. This manuscript is followed by a short review article summarising current trends in food and dietary applications of flaxseed mucilage. The first publication describes more likely the traditional use of flaxseed mucilage for food fortification to enhance the technological, nutritional or sensory quality of foods or to provide health benefits. The second review paper focuses exclusively on the potential use of flaxseed mucilage in recent and innovative food industry and nutrition areas. In modern applications, flaxseed mucilage can be applied, for instance for preparing films, for food protection, as a structural component in oleogels, cryogels or aerogels, and it may modify the functional properties of proteins within composites. From the point of nutrition, flaxseed mucilage can serve as an encapsulating agent for probiotics or biologically active compounds. Flaxseed mucilage has the characteristics of a prebiotic and may increase the proportion of beneficial probiotic microorganisms. As a result, both review articles highlight the significant potential of flaxseed proteins and flaxseed mucilage for various recent and future applications. The second part of this thesis represents a first-authorship original manuscript focused on researching the influence of variety and growing conditions on yield parameters, chemical composition, lignan content and antioxidant potential of flaxseeds.

Heinrich Schliemann: autobiography
Murzina, Daria ; Čechura, Jaroslav (advisor) ; Jarošová, Markéta (referee)
On January 6, 2022, is 200 years have passed since the birth of Heinrich Schliemann. He is called the Founder of Mycenaean archeology, archaeologist-amateur, gold digger, impostor, and even a charlatan. Schliemann was born in a small Prussian township but lived an extraordinarily bright life, the ultimate success of which was the excavations of ancient Troy and Mycenae. Heinrich Schliemann considered himself this not only fate but he felt that he was born for this purpose. Is it so? Does the "Dream of Troy" have its roots in Heinrich's childhood? Which of what Schliemann wrote about himself can be trusted, and which is deception, exaggeration, or adoption? The thesis dedicates to the historical and philological analysis of all autobiographies of Heinrich Schliemann to bring all known biographical information to a common denominator, filtering out mystifications and obvious borrowings, separating real facts from embellishments and hyperbole as well. Keywords Heinrich Schliemann, Autobiography, Literature, traveling, Troy, Fraud

Architecture of Franciscan Observant Monasteries in Bohemia, Moravia, Silesia and Upper Lusatia in Second Half of the 15th Century
Křenková, Zuzana ; Kuthan, Jiří (advisor) ; Jakubec, Ondřej (referee) ; Jarošová, Markéta (referee)
So far the history of medieval Franciscan Observance has been considered as the history of individual monasteries, or more generally as the history of disputes concerning education, culture and nationality. The aim of the present dissertation is to describe the history in terms of cultural history, to analyze wider issues of architecture regarding monastic buildings of the last big monastic community of The Middle Ages, to describe them and evaluate. The basic structure of the dissertation consists of monographic chapters monitoring the history and building development of fifteen preserved and thirteen extinct monasteries in territory of the Czech monastic province (Bohemia, Moravia, Silesia and Upper Lusatia). The catalogue part is introduced by chapters summarizing the historical context of Franciscan Observants' activities within a short period between the second half of the 15th century and the first half of the 16th century, during which the Observants of the Czech province experienced both the stage of raise and decay. The history of the order is then followed by an essay on the rules of the process of foundation constructions of the convents, the order rules limiting artwork and mainly the character of the order architecture. Key words Franciscan Observants, Late Gothic Architecture,...

Comparison of texts and images of Visitatio Sepulchri in the region of northern Spain and southern France in the Middle Ages
Kuliešiūtė, Indrė ; Royt, Jan (advisor) ; Jarošová, Markéta (referee)
Bibliografická citace Comparison of texts and images of Visitatio Sepulchri in the region of Northern Spain and Southern France in the Middle Ages [rukopis] : diplomová práce / Indrė Kuliešiūtė; vedoucí práce: Jan Royt. -- Praha, 2023. -- 47 s. Abstract The Bible tells of an event when several women meet one or two angels by the empty Tomb of Christ. Such motive in art is called the Holy Women at the Empty Tomb or sometimes the Three Maries at the Sepulchre. The goal of this thesis is to explore the connection between the images of this motive in the Southern France and Northern Spain to the Easter dialogues and liturgical plays that tell this story. The peculiarity in this region is the gestures of the angel and sometimes of the women: they are depicted in the action of lifting the lid of the sarcophagus to look inside. To my best knowledge, such an arrangement does not occur even once outside of this region. To achieve the goal of the thesis, the artworks and the drama texts from this region were surveyed. The artwork was analyzed, focusing mostly on the gestures of the figures, while the discussion of the drama texts focused mainly on the rubrics, instructing the performers what actions and how they are to carry out. This thesis argues that the greatest variety and originality of the artworks is where...

Quality of selected meat products produced in standard and organic quality
JAROŠOVÁ, Martina
The aim of this Master thesis was to compare the presence of used preservation substances and basic ingredients in meat products made in regular and bio-quality. In practical part of the thesis, a polarization measurement was done with the aim to determine whether there is a quality difference between these two production qualities. The obtained data were subsequently processed and statistically evaluated. The statistical evaluation showed that the basic composition of meat products in regular and bio-quality is basically identical in percentage. Furthermore, the frequency of used preservation additives in different foods was statistically evaluated as well. In conclusion, food products in bio-quality showed 0.7 less additive content compared to regular food product, however, the difference was still weighed as statistically insignificant.
