Bob Krčil
Douša, Jan ; MOUCHA, Josef (advisor) ; Buddeus, Hana (referee)
The life and work of Bob Krčil have so far been known from fragments and unsubstantiated legends. The aim of this essayistic piece is to lay out the deeper motives of his personal trajectory, photographic oeuvre, and activities for the Czech exile community. Krčil’s photographic body of work is inseparably connected with his eventful life. The writing of the thesis was preceded by tracking down and putting together Krčil’s fragmented estate, sorting out his correspondence and writings, and interviewing people who knew him personally. By drawing on these materials, the thesis aims to provide insight into the life and motivations of this important figure of Czech exile culture.

San Minn (or) An Artist who prefer creating and paintings than his life
Zeya, Pyin Nyar ; JANEČEK, Vít (advisor) ; VOJTĚCHOVSKÝ, Miloš (referee)
No one can control a painter artist’s freely thoughts and ideas and although his paintings were under the high pressure and banned by force, the artistic value of his materials never go down. So that I am writing this paper.
He, San Minn has broken out the mainstream of Burmese painting field, he never made business paintings as well. He keeps his belief on the art of paints and he is always finding for the new way to make his paintings. His materials are very different from other Burmese painter artists’ materials. His style is unique in Burmese paintings. So I can get a chance to study of his style, ideas, ways of thinking and his determination on the art works.
My paper can show a painter artist’s life who grew up under the military rule for 50 years and the situation and history of Burmese painting field. Then not only people who are studying the painting subject, but also other people can know about the subject of Burmese painting and field of artists. I dare say that my paper must be colorful and fruitful.
As a painter artist, it seems that he wants his audience to feel his materials but he rare to show his real life behind the pictures. For me, I can get a chance to know about his real life for my thesis paper.
xxxxxxxxxx
Thesis Statement
My thesis can be useful for everybody who is interested in Burmese contemporary art field.
This is the biggest chance to read about one of the most famous, important and significant artists and art movements of Burma. His paintings are reflecting his journey through over 40 years of censorship, but he was not afraid to tackle political and social issues.
Many of San Minn's art works are based on autobiographical, making sharp social commentary on the popular culture, social values and scenario circumstances where he has lived in.

Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.

Plasma spraying from liquids: plasma liquid interaction and coating build up
Tesař, Tomáš ; Mušálek, Radek ; Medřický, Jan ; Lukáč, František
Plasma spraying from liquid feedstocks is a rapidly developing field of thermal spraying since the coatings prepared from liquids exhibit some unique features, such as high hardness, thermal shock resistance or low thermal and electric conductivity. The key factor influencing the final coating character and properties is the input material which may be in the form of a suspension or a solution. Parameters of the selected suspension (solids concentration, viscosity, surface tension, chemical composition, etc.) or solution (concentration, etc.) determine its interaction with the plasma jet which strongly influences the coating buildup. This proceeding introduces the problematics of the interaction between the liquid feedstock material with the plasma jet and presents the way of evaluation of the coating buildup.

Natural houses in gardens
Formánková, Kristýna ; Kunt, Miroslav (advisor)
Thesis discusses natural houses which are supposed to be part of our lives in the future. These houses may be for someone and they might prefer smarter building with non-recyclable materials when choosing a new housing. But it is necessary to think about our future and sustainable development. We also need to tell ourselves what is really a priority for our planet. There comes a time when they will prefer building materials which can be used somehow after some time or be recycled. This is related to the design of the garden. It is designed to fulfil an ornamental, economic and social function. The garden is an integral part of each house, therefore it is important for each element used to be creating the garden as a linked harmonious whole. The study deals with the concept of a natural houses home in accordance with the maximum use of the garden.

Erosion protection of slopes from assignment to implementation
Konopecká, Vladislava ; Janeček, Miloslav (advisor) ; Kalibová, Jana (referee)
The thesis is following up on the findings to the issues presented in the Bachelor's thesis, where they were described mainly the methods and materials used to secure the slopes of pipeline, will address not only the final solution method of protection against erosion of the slopes, but in particular all conditioning influences such as the topography, the type and quality of rock and soil in the area of the building, surrounding buildings, and last but not least property relations that can significantly affect the design solution in terms of difficulty of implementation, durability, aesthetics and economic performance of the resulting construction works. Alpha-Omega of the initial phase is the analysis and the interdependence of the issues just for land consolidation, anti-erosion measures, construction procedures in accordance with the geology of the chosen territory and the intended realization of the construction project. The evaluation of the risks associated with this issue on the basis of field investigation, examination with a valid legal legislation, SWOT analysis will be ended.

Time lapse tomography of fracture progress in silicate-based composite subjected to the loading a combination with acoustic emission scanning
Kumpová, Ivana ; Kytýř, Daniel ; Fíla, Tomáš ; Veselý, V. ; Trčka, T. ; Vopálenský, Michal ; Vavřík, Daniel
The initiation and propagation of a fracture in quasi-brittle materials (such as silicatebased composite) is an increasingly discussed topic for which various methods of research have been developed/applied. As the quasi-brittle silicate-based composite compounds are very non-homogenous, the mechanism of the crack initiation and propagation can be very different even for samples with the\nidentical geometry. One possible approach to study the fracture mechanism in quasi-brittle materials is to use several different experimental techniques in a single experiment and perform detail analysis to identify generally valid fracture process phenomena. In this work, a simultaneous monitoring of fracture\nprocess zone formation and propagation by three different methods is presented and discussed. A three point bending test was performed on a notched silicate composite specimen. During the loading process, a highly accurate force displacement dependence was recorded accompanied with X-ray radiography,\nX-ray computed tomogra-phy and acoustic emission scanning.

Possibilities in monitoring of laser welding process
Horník, Petr ; Mrňa, Libor
With increasing demands on the quality of the welds, it is usual to apply automated machine welding with monitoring of the welding process. The resulting quality of the weld is largely affected by the behavior of keyhole. However, its direct observation during the welding process is practically impossible and it is necessary to use indirect methods. At ISI we develop optical methods of monitoring the process based on analysis of radiation of laser-induced plasma using Fourier and autocorrelation analysis. Observation of keyhole inlet opening is partially possible through a coaxial camera mounted on the welding head and the subsequent image processing. A high-speed rear camera to understand the dynamics of the plasma plume. Through optical spectroscopy of the plume, we can study the excitation of elements in a material. Shielding gas flow can be visualized using schlieren method.
