Sepulchral monuments in the heritage conservation practice
Roháček, Jan ; Müller, Karel ; Chlíbec, Jan ; Slavík, Jiří
The methodology book pioneers in presenting the forms and evolution of Christian sepulchral monuments dated from the Middle Ages to the 20th century, their decoration and epigraphic suit. The main part of the methodology book consists of chapters on recording, documentation, preservation and presentation of sepulchral monuments. The chapters on epigraphic and heraldic accessories are aimed to be directly used as sources for sepulchral monuments' recording. A lot of attention is paid to managing records of the monuments in the environment of the heritage conservation integrated information system.

Biological control of plant pathogens
Chudý, Michal ; Ryšlavá, Helena (advisor) ; Müller, Karel (referee)
Heat shock proteins (HSPs) play a major role in protecting cellular proteins, acting as chaperones, preventing aggregation of partially damaged molecules, and help the protein repack, repair and create its right three-dimensional structure. Their synthesis occurs mainly during the stress state of the cell or the whole plant. Biotic forms of stress induce the expression of pathogenesis-related proteins (PRs), which are often characterized by enzyme activity, such as glucanases, chitinases and peroxidases. In this work, the effect of infection with fungal pathogens Alternaria brassicicola and Verticillium longisporum on the content of HSP70, HSP90 and PR-1, PR-2, PR-3 was followed in the tomato plants (Solanum lycopersicum L. cv. Micro-Tom) and rapeseed plants (Brassica napus subsp. oleifera). The seeds were treated with isolates of oomycete Pythium oligandrum, which is one of the unique and commercially available biological control agents. HSPs and PRs proteins were detected immunochemically on a nitrocellulose membrane. Immunochemical analysis showed the interaction of primary antibodies against HSP70 and HSP90 with low relative molecular weight proteins. Infection with Alternaria brassicicola and Verticillium longisporum increased the representation of 33 kDa - 43 kDa proteins. Seed treatment with...
New insights on auxin metabolism
Helusová, Lenka ; Müller, Karel (advisor) ; Ryšlavá, Helena (referee)
Auxin is the longest known phytohormone with many functions. It participates in the development of embryo, in vegetative and generative development, plant stress reaction, and also in their senescence and death. Activity of auxin in plant cells and tissues is quite often compared to the effect of morphogens, i.e. the effect of substances, whose concentrations induce a strictly defined response in tissue and organ formation. Apart from intercellular and intracellular auxin transport, the main determinants of auxin concentration gradients are its biosynthesis and metabolism. Regardless of the long-lasting study of auxin, the complexity of metabolic pathway regulation is still not well known. The aim of this thesis is to summarize current knowledge of the metabolism of auxin in plants, i.e. its biosynthetic pathways, conjugation and oxidation, and put them into a context with older results.
The effect of rape seed treatment with oomycete Pythium oligandrum on plant metabolism
Vaverová, Kateřina ; Ryšlavá, Helena (advisor) ; Müller, Karel (referee)
Lot of attention is paid to biological control agents of plant pathogens as it will reduce the amount of pesticides used in agriculture. Pythium oligandrum oomycete is already used commercially in the form of watering and spraying. In this work the properties of other isolates were characterized, and the metabolic changes were studied in plants of oilseed rape (Brassica napus subsp. Oleifera), whose seeds were treated with preparates based on Pythium oligandrum. In the first part of the thesis the properties of compounds secreted by isolates of Pythium oligandrum were tested. The amount of phenolic substances and the activity of endoglycosidase endo-β-1,3-glucanase, cellulase, chitinase as well as proteases were measured to assess the ability of oomycete Pythium oligandrum mycoparasitically protect the plant. Substances, especially oligandrin, which during interaction with the plant are responsible for "priming", have been observed, enabling the plant to respond rapidly to pathogen infection through systemic plant resistance. Differences between individual isolates also manifested themselves in electrophoretic separation in the protein representation. In the second part of the work, the effect of rapeseed seed treatment with isolates of Pythium oligandrum on plant metabolism was monitored. While...
Dehumanization as a risk factor for the use of digital technologies in the context of social work
Brezina, Lukáš ; Vrzáček, Petr (advisor) ; Müller, Karel (referee)
The thesis deals with the threat of dehumanization when applying digital technologies and robotics into social work. The work focuses on the history and origin of digital technologies within the context of social changes. It explores the basic rules governing elementary functioning and development of digital technologies and robotics. The thesis describes and summarizes basic information about the possibilities and risks of using digital technologies and robotics within social work. Towards the end it also includes opinions of several professional and political authorities who are active in this topic. This thesis aims to trigger the debate over the possible threats connected to dehumanization of social work and the use of digital technologies and robotics, respectively make it more intensive.
Historico-Sociological Analysis of the Sharing Economy from its Early Digital Foundations to the Present
Martos Carrion, Esther ; Blaive, Muriel (advisor) ; Müller, Karel (referee) ; Maslowski, Nicolas (referee)
The main goals of this project are; (1) to explore what sort of consequential events have made possible the emergence of the sharing economy, (2) to observe how this socio- economic system has evolved over time, (3) to identify current drivers, typologies, challenges and other aspects of consumer behaviour attached to this digital phenomenon and, (4) to monitor the user traffic (2015-2017) of remarkable sharing economy platforms including the social network Facebook. Although the sharing economy still yet being a new paradigm, this dissertation aims to explore the subject from a historico-sociological perspective taking into consideration events occurred from the 80's onwards. This study addresses qualitative and quantitative data collected from the literature review, 22 personal interviews with experts on the field and web tracking systems. As a principal outcome, this dissertation will provide a theoretical approach in which the brief history of the sharing economy will be argued in detail.
