Petr, Martin ; Maršáková, Kateřina (advisor) ; Nováková, Tereza (referee)
Author: Martin Petr Supervisor: Mgr. Kateřina Maršáková Title: The case study of physiotherapeutic treatment of a patient after total hip arthroplasty Objectives: The aim of this bachelor thesis is to summarize in the general part information concerning osteoarthritis and total hip arthroplasty and in the special part to elaborate a case study of physiotherapeutic treatment of a patient with this diagnosis. Methods: This thesis is divided into two main parts. The first is the general part, which contains information about osteoarthritis and hip alloplasty. The manifestations of osteoarthritis, its diagnostics, distribution, causes and treatment options are mentioned. For alloplasty, surgical approaches, complications associated with surgery, types of joint replacements and possible rehabilitation procedures are listed. The second part of this work is a special section, which includes a case study of a patient after total hip arthroplasty. It consists of medical history, initial kinesiological analysis, short- and long- term therapeutic plan, course of individual therapeutic units, output kinesiological analysis and therapy effect evaluation. Results: The stated goals of the short-term therapeutic plan were met. The patient left the rehabilitation clinic fully self-sufficient and, compared to the...
Ultrathin films deposited by means of magnetron sputtering and their characterization
Petr, Martin ; Kylián, Ondřej (advisor) ; Straňák, Vítězslav (referee) ; Tichý, Milan (referee)
Presented work is focused on the deposition and characterization of thin and ultrathin plasma polymer films, then also on the preparation of nanocomposites metal/plasma polymer. The characterization of plasma polymer films was partly done in-situ without exposing the samples to the atmosphere. The thickness of prepared films was measured by spectral ellipsometry, the chemical composition was measured by XPS. The morphology and optical properties of deposited films were measured ex-situ. It is shown that during the initial stages of growth the properties of plasma polymer films depend on their thickness and also on the material of the substrate. Many interesting applications were explored for prepared nanocomposites metal/plasma polymer. They can be used as superhydrophobic coatings, gradient coatings, substrates for Raman spectroscopy or as antibacterial coatings. Moreover, special optical properties of prepared nanocomposites were studied in detail. Presented work has an experimental character.
Handwriting recognition using neural network

Title: Handwriting recognition using neural network Author: Martin Petr Department: Department of Theoretical Computer Science and Mathematical Logic Supervisor: RNDr. Pavel Surynek, PhD. Supervisor's e-mail address: pavel.surynek@mff.cuni.cz Abstract: Pattern recognition finds its use in many fields whose development has been affected by computer science and computer technology. Among these, the conversion of handwritten or printed text into computer-encoded text has a particularly prominent position. In the presented work we propose a method for recognizing handwritten characters in real-time using feedforward neural network as the basic classification mechanism. Dealing with differences among individual instances of each handwritten character we thoroughly explored the possibility of suppressing these while emphasizing characteristics that are essential for successful recognition. For these purposes we employed discrete cosine transform, whose time-proven application in audio and video signal processing or even directly in the field of pattern recognition provided a convincing argument for us to use it in our work as well. As a means of suppressing variations among various writing instruments we proposed preprocessing of input images using binarization and skeletonization. The designed method was...
Depozition of hydrophobic fluorocarbon coatings by plasma polymerization methods
Petr, Martin
In this work we study the deposition of hydrophobic fluorocarbon coatings by magnetron sputtering of polymeric PTFE target. We show what is the influence of the conditions of the deposition process - the pressure in the chamber, the RF power - on the properties of the resulting CFx thin films (their chemical composition, morphology, wettability, barrier and optical properties, stability and possible bio-aplications). In this work we use a novel way to control the morphology and the chemical composition of the surface of thin films independently by using nano-particles, both metal (Pt, Cu, Al) and polymeric (C:H, Nylon). With nano-particles we can control the hydrophobicity of thin films and we can prepare super-hydrophobic films. Work has an experimental character.
Exhibition gallery in Brno
Petr, Martin ; Herman, Adolf (referee) ; Bantová, Sylva (advisor)
The subject of this diploma thesis is the design of exhibition gallery in the city center of Brno. The exhibition gallery consist of exhibition rooms, depositories, lecture hall, café, VIP room, entrance and communication spaces, hygienic facilities for visitors and employees, administrative premises of the gallery, air-conditioning and heating machinery. The SO01 object is processed in detail, the object SO02 is processed in the form of a study. Design of the exhibition gallery is based on the requirements of the student competition, the sponsor is Xella CZ, s.r.o. SO01 is designed as a four-storey building with three above-ground and one underground floors. The building has an exhibition area, a lecture hall, a café, a VIP room, entrance and communicative spaces, hygienic facilities for visitors and employees, air-conditioning machinery. The supporting structure of the building is designed as an assembled, prefabricated, reinforced concrete skeleton. Ceiling structures are designed as SPIROLL 250 mm pre-stressed ceiling panels. The facade is designed as two-layer ventilated. The exhibition gallery is designed with a single-layer flat vegetation roof.

Nuclear myosin 1 and its role in the regulation of plasma membrane tension
Petr, Martin ; Hozák, Pavel (advisor) ; Malínský, Jan (referee)
Myosin 1c (Myo1c) is a molecular motor involved in regulation of tension-gated ion channels, exocytosis, endocytosis, motility and other membrane-related events. Moreover, it acts as a dynamic linker between the cell membrane and cortical actin network, contributing to the maintenance of plasma membrane tension. In contrast, nuclear myosin 1 (NM1), an isoform of Myo1c, has been described only in the nucleus where it participates in various nuclear processes, including transcription or chromatin remodeling. However, although traditionally regarded as exclusively cytoplasmic or nuclear, all myosin 1c isoforms participate in nuclear functions and they are present in the cytoplasm as well. The main focus of this study was to characterize the functional significance of NM1 in the cytoplasm. We have found that NM1 localizes to plasma membrane and shows a uniform punctuated distribution with a high concentration at the cell periphery. Moreover, atomic force microscopy measurements of mouse NM1 KO fibroblasts revealed a significant increase in an overall plasma membrane elasticity in comparison to WT cells, indicating a disruption in the regulation of plasma membrane tension caused by the loss of NM1. Since a higher membrane elasticity and deformability is a characteristic marker of cancer cells,...

Promoter-terminator interactions in eukaryotic RNA polymerase II transcription
Petr, Martin ; Hozák, Pavel (advisor) ; Vaňková Hausnerová, Viola (referee)
Gene loops are chromatin structures formed by juxtaposition of distal genomic regions. Since these regions are often involved in transcription cycle control, gene loops therefore provide another mechanism of regulation of gene expression. This thesis summarizes recent findings about gene loops, focusing specifically on loops formed by interactions between promoter and terminator regions of genes transcribed by the eukaryotic RNA polymerase II. Different cases of gene loops discovered in several yeast genes, the mammalian BRCA1 tumor suppressor and the HIV-1 integrated provirus are described, including mechanisms that possibly lead to the formation of these structures. Since gene loops and interactions between promoter and terminator in yeast have been linked to the transcriptional memory, their involvement in this phenomenon is discussed. Finally, as BRCA1 and HIV-1 are directly linked to serious human diseases, the potential significance of alterations of gene loops in the development of various pathological conditions is presented. Keywords: gene loops, chromatin loops, chromatin conformation, transcriptional memory, transcription, gene expression, regulation
