Skinhead subculture within post-industrial era and its possible development through the eyes of its own members
Jakubčanin, Petr ; Maslowski, Nicolas (advisor) ; Urban, Lukáš (referee)
This diploma thesis is based on the essence of the subculture anchored in the post- industrial era. Through the relevant literature, I theoretically analyze the relationship of the skinhead subculture to the dominant culture and uncover its characteristics formed mainly by the influences of globalization, actual capitalist system and mutual interaction of various social factors. I also focus on the specific signs and internal differentiation of the subculture, which are related to its politicization. In the empirical part, I focus on answering research questions through qualitative research, which aims to reveal the emic perception of subculture in the post-industrial era through the eyes of its members themselves. The testimonies of skinheads about the current state of their subculture and its possible future development are then thoroughly analyzed and interpreted.

Interactive architecture
Müller, Tomáš ; Stavric, Milena (referee) ; Kaftan, Martin (advisor)
Interactive architecture The world today is constantly dynamically changing. Along with the world, the environment in which people live is changing as well. Architecture, which has been focused on improving and enhancing the surrounding environment for the benefit of mankind since the beginning of humanity, now has the opportunity to come to life and become interactive thanks to technological advancements. Interactive architecture, which dynamically adapts to changing conditions and human needs, can lay the foundation for a robust and adaptable solution that could contribute to more resilient and sustainable architecture in the future. In this work, the use of contemporary digital design techniques will allow the potential of the ancient art of origami - the art of folding paper - to be combined with today’s technology. Thanks to this connection, it is possible to create architecture that will be able to change and adapt to various human needs. This thesis focuses on the digitisation of origami, the development of structures inspired by the Miura origami pattern, the transition from paper shells to kinetic movable shells, and the development of a digital tool capable of designing and controlling the behaviour of interactive shells. The behaviour of the interactive components will be tested through digital simulations.

Canistherapy
HOLEMÁ, Hana
The bachelor thesis deals with the topic of canistherapy. The theoretical part defines the concept of canistherapy, the subject of its research, target groups and users of this treatment. The thesis defines the aims, forms and methods, as well as its risks. It briefly describes the abilities, skills and suitability of the canistherapy dog and deals with the prevention of its abuse. The practical part also advocates a survey. The main aim was to find out what kind of relationship the dog and its owner, as handler, have with each other. It also looks at which dogs are suitable for canistherapy and their mental and physical health. Last but not least, what effect the contact with the dog has on the client and what are the possibilities to prevent abuse of the therapy dog.

The influence of humic acids methylation on the interaction of surface active agents
Bělušová, Anna ; Weidlich, Tomáš (referee) ; Smilek, Jiří (advisor)
The presented diploma thesis deals with the study of interactions between humic acids as the main component of soil organic matter with a model organic pollutant presented by cationic surfactant Septonex (which was expected to interact positively with humic acids due to its charge) through unconventional combination of dialysis and diffusion techniques realized in diffusion cells together with isothermal titration calorimetry capable of elucidating the nature of ongoing reactions from a thermodynamic point of view. The experiments were performed with a humic acid isolated by standard isolation procedure from Leonardite (1S104H) purchased from the International Society for Humic Substances, with humic acids isolated from lignite as well as modal chernozem. The aim of the submited diploma thesis is to assess the influence of carboxyl functional groups in the structure of humic acids to interactions with Septonex. For this reason, said samples of humic acids have been modified by selective methylation of their carboxyl functional groups, which can no longer participate in interactions with ionic substances. Results from diffusion cells and isothermal titration calorimetry confirmed the assumption that Septonex interacted with all types of unmodified humic acids more than with their methylated derivatives. Despite the available literature, it was surprising that the differences in the interaction of humic acids with Septonex were not diametrically different when comparing unmodified humic acids with their methylated derivatives. The extent of these interactions was assessed through the apparent equilibrium constant Kapp determined in the diffusion (dialysis) experiments and from the course of enthalpy curves from isothermal titration calorimetry. After the experiments and their evaluation, it can be concluded that humic acids and Septonex in their interactions, due to their structures, probably apply not only electrostatic interactions, especially through available carboxyl functional groups of humic acids and positively charged hydrophilic parts of Septonex molecules, but also a significant role have a hydrophobic effect, hydrogen bonds and Van der Waals forces.

Viscosimetry of hyaluronan-amphiphile systems
Trojan, Martin ; Běťák, Jiří (referee) ; Chytil, Martin (advisor)
This bachelor thesis investigates the interaction between the polysaccharide sodium hyaluronate (HA) and some amphiphilic molecules. As amphiphilic molecules the aminoacids lysine and 6 – aminocaproic acids were chosen. The presence of the carboxylic group on HA and the aminogroup on the aminoacids suggests electrostatic interaction between these two compounds. This supposal offers the possibility to modificate HA and uses it as a new type of a carrier of bioactive compounds, for example medicals. The HA of two molecular weights (1.75MDa and 70kDa) were chosen for the study of the interactions with the aminoacids. Solutions of HA and stock solutions of the aminoacids were prepared for their mutual mixing in the various volume ratios. The solutions and the mixtures were measured in three types of environment: pure water, 0.15M solution of NaCl and in phosphate buffer (PBS) of pH 6. The interactions were investigated by means of reometry. Our results show, the presence of interactions between HA and the aminoacids mainly in the system consisting the 1.75 MDa HA and lysine in water. As a result of the interactions, a decrease in the viscosity of the mixtures comparing to the HA solutions was observed.

Preparation, characterization of trimethylchitosan and verification of its interaction ability with regards to variable charged ionic compounds
Bayerová, Zuzana ; Pekař, Miloslav (referee) ; Smilek, Jiří (advisor)
The aim of this thesis is to study the interactions of trimethylchitosan with oppositely charged substances with regard to its potential biomedical use. A substantial step before the study of interactions was a successful synthesis of trimethylchitosan, which was subsequently confirmed by characterization of the final synthesis product using physico-chemical methods (infrared spectroscopy, elemental analysis, nuclear magnetic resonance). The result product was subjected to negatively charged interactions such as sodium dodecyl sulphate as a representative of the ionic surfactant, alginate as a natural polysaccharide representative and Chicago Blue as a representative of the anionic dye. The ability to interact with sodium dodecyl sulfate and alginate was demonstrated by the formation of hydrogels, which were subsequently characterized by mechanical viscosity tests using rheometric properties. The positive affinity of trimethylchitosan for organic dyes has been investigated in agarose-based support hydrogel matrices for changes in transport and barrier properties.

Artificial Vocal Folds for Source Voice Generation
Vašek, Martin ; Vampola, Tomáš (referee) ; Kamenický, Ján (referee) ; Mišun, Vojtěch (advisor)
The first part of this work focuses on ways to replace missing source voice in case of patients after total laryngectomy. The commonly used methods of voice rehabilitation are mentioned. Simple computational models are used to explore several principles of generating artificial source voice. Based on the knowledge of how a healthy human voice is generated, one of the ways to generate artificial source voice was chosen – a reed-based element in the configuration (-, +). The function of the reed-based element is based on a periodic bending of the reed and in the airflow cutoff created by this motion. The (-,+) configuration of the reed-based element causes a different behaviour, when compared to healthy vocal folds, important is, however, whether the generated acoustic signal has the right spectral characteristics, which enable the generation of voiced vowels of the human speech. Both experimental and computational models are used to study the behaviour of the reed-based element. The design of the experimental model is based on the preliminary experiments with simple reed-based elements, which were carried out at the beginning of my studies. The new experimental model is designed in such a way, that it enables changes to the reed geometry and its position towards the reed stop. The measurements carried out on the experimental model are mainly acoustical (measurements of the generated acoustical signal), but optical measurements of the reed´s movement and position are possible and used as well. Because of the nature of the reed-based element´s behavior, the fluid structure interaction must be taken into consideration in the computational model. A two-way model of fluid structure interaction is used between the fluid part of the computational model and the structural one. A partitioned solution is used to solve the fluid-structure interaction. The effect of specific input parameters on the function of both models (experimental and computational) is monitored. The influences of input parameters on the basic frequency of the generated signal (source voice), on the stability of the function and on other important characteristics are evaluated. The final chapters focus on the design of voice prosthesis in general. Some specific issues, which need to be solved when designing voice prosthesis, are highlighted.
