The use of assistive devices for patients with Bechterev disease
KULHÁNKOVÁ, Barbora
The theoretical part of the thesis describes the actual disease. It is a rheumatic disease which includes inflammatory processes located in the spinal area. The disease is also called Ankylosing spondylitis. Typical symptom of the Bechterew's disease is stiffness and consequent back pain. Successful treatment must include use of nonsteroidal antirheumatic drugs and pain-relievers. However, the most crucial element is regular physical training, which must not be avoided otherwise the client may become permanently disabled and need assistance. The successful treatment also in cludes repeated spa stays. The thesis also deals with the role of a nurse, who together with a professional team, including physiotherapists, ergotherapists and social workers, care for the client's needs as well as for his/her education and his/her family members' education. The nurse should emphasize the importance of regular physiotherapies and use of prescribed drugs to the patients with such diagnosis. The most crucial part of the thesis deals with compensation aids which allow the clients relieving pain when moving and which get the patients back in their common lives. The patients start to use the compensation aids, such as walking sticks, wheeled walkers, and hygienic aids with long handle, in advanced stages of the disease, when common movements are difficult and painful for them. Furthermore, I am writing about the possibility of renting or purchasing such aids. There are compensation-aid rental companies and shops which offer such aids. Another part of the thesis deals with compensation allowance, which the clients may receive from their insurance companies.It also describes changes in the patient's life and environment, which may occur after receiving the compensation aids. The major goal of the thesis is to describe the possibilities of usage of compensation aids by the Bechterew's patients. To reach that I have chosen two survey questions. The first one reveals the type of compensation aids the clients prefer using and the way how they get these. The latter question explores influence of the compensation aids to the clients' lives. The survey was done by qualitative research method. For this purpose, semistructured in-depth interview was conducted with clients who suffer from the Bechterew's disease and who use compensation aids for their everyday routines. The obtained information shows that the most used aids are those which we are typical for people with movement disorders. Mostly, the clients pay for their aids by themselves. Vouchers prescribed by doctors are only used to get the forearm crutches. The Bechterew's disease is still an incurable disease. It may have very serious consequences for the patients unless they execute regular physiothe rapy, repeated spa curative stays and use the medicaments. The thesis may be used as a source material for special brochures created for mobility-impaired clients.

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.

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.

Properties of Aerosol, Produced by Laser Ablation of Standard Materials for ICP-MS Analysis.
Holá, M. ; Nováková, H. ; Ondráček, Jakub ; Vojtíšek, M. ; Kanický, V.
Laser ablation (LA), together with inductively coupled plasma mass spectrometry (ICP-MS) as a detection system, has become a routine method for the direct analysis of various solid samples. The product of laser ablation contains a mixture of vapour, droplets and solid particles. All components are finally transported to a plasma by a carrier gas as a dry aerosol including mainly agglomerates of primary nanoparticles. In general, characterisation of aerosols by their particle size distribution (PSD) represents indispensable tool for fundamental studies of the interaction of laser radiation with various materials. The particle size distribution of dry aerosol originating from laser ablation of standard material was monitored by two aerosol spectrometers – Fast Mobility Particle Sizer (EEPS) and Scanning Mobility Particle Sizer (SMPS) simultaneously with laser ablation - ICP-MS analysis.\n

FRACTURE MECHANICS ASSESSMENT OF CRACKED WELDED POLYOLEFIN PIPES
Mikula, Jakub ; Ševčík, Martin ; Hutař, Pavel ; Náhlík, Luboš
The aim of this paper is to present methodology for estimation of fracture mechanics parameters in polyolefin pipes with an axially oriented crack using three dimensional numerical analyses. Linear elastic fracture mechanics is used for description of fracture behavior. In the paper, three different variants of pipe weld with an internal axial semi-elliptical crack are studied. Numerical models correspond to a cracked pipe containing material nonhomogeneity in the welding area caused by welding process. A critical locations of the crack initiated along the pipe wall is found and the stress intensity factor for such cracks with real crack shape are numerically estimated in these critical locations. The methodology presented here can be used for estimation of residual lifetime of welded polymer pipes containing crack.

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.

Generace vířivosti rychlostního pole gradientem entropie
Novák, Martin ; Maršík, František (advisor) ; Grmela, Miroslav (referee)
The master thesis studies the impact of the entropy gradient on the vorticity of ve- locity field, particularly by applying the linear momentum balances. These balances are formulated for Thermo-viscous fluids (later fluids) and Thermo-viscous-elastic ma- terial (later solids) with the other balances (energy, mass, etc.). In order to derive these balances, the Classical continuum mechanics approach is used along with the respec- tive Variational principles. The thesis emphasizes the Variational principles applica- tion representing the modification of the Bateman principle [Bat29] and its comparison with the Classical approach, linked to the L. Crocco work [Cro37], particularly in the case of vorticity generation. It is pointed that by the definition of the dissipative en- tropy sdis a harmony of both approaches can be achieved and that, in the case of an appropriate limit, the direct effect of the entropy gradient on the vorticity of velocity field can be demonstrated. By applying this conclusion the relationship between the change of circulation among a closed curve and released heat on the given geometry is indicated.
