Preparation and optical properties of scintillation oxide layers
Hanuš, Martin ; Kučera, Miroslav (advisor) ; Čuba, Václav (referee) ; Pejchal, Jan (referee)
In this work we studied properties of garnet scintillator layers (RxLu3-xAl5O12, RxY3-xAl5O12) doped by rare earth ions (Ce, Pr, Tb), orthosilicates (Y2SiO5; R = Ce, Tb) and influence of Sc codoping on Pr3+ and Tb3+ emissions. The Zr codoping on Ce3+ emission in orthosilicates was also studied. The samples were prepared by liquid phase epitaxy. The studied materials show high quantum efficiency and good chemical and mechanical stability. They represent ideal materials for 2D imaging devices. We studied optical absorption, excitation and emission spectra and scintillation properties (radiolunescence and photoelectron yield). The aim was to determine the properties of grown layers and their comparison to Czochralski grown single crystals. We looked for the impact of melt and growth conditions on measured layer properties. We also tried to determine optimal amount of dopants in layer. We used PbO - B2O3 and BaO - BaF2 - B2O3 fluxes. Using these fluxes, we succeeded in growing layers with less intrinsic defects in crystal lattice in comparison to single crystals. In grown layers of thickness from 1 to 30 µm higher dopant concentration was achieved than in single crystals.

Optical properties of thin film scintillators
Onderišinová, Zuzana ; Kučera, Miroslav (advisor) ; Mareš, Jiří A. (referee)
In the present work we studied Pr, Sc co-doped and Eu-doped Lu3Al5O12 thin epitaxial garnet layers prepared by liquid phase epitaxy (LPE) on Y3Al5O12 (YAG) and Lu3Al5O12 (LuAG) single crystalline substrates. In the process of growth BaO - BaF2 - B203 (Pr, Sc co - doped layers) and PbO - B2O3 (Eu - doped layers) fluxes were used. These materials are considered perspective scintillators with high density, fast scintillation response, high quantum e fficiency and good chemical and mechanical stability. They are used in a number of applications in which high spatial resolution is required. The absorption, emission and excitation spectra of experimental samples were measured and investigated. Our attention was focused especially on the study of infuence of Sc3+ ions on the emission properties of Pr3+ ions in epitaxial layers which mutually contain various amounts of concentrations of dopants. The Sc3+ ions do not show any radiative transitions in visible and UV spectral regions, but they increase the scintillation response of Pr3+ ions. This phenomenon is caused by overlappig of the Sc-related emission around 275 nm with the 4f-5d absorption band of Pr3+ centers. By measurement of radioluminescence this energy transfer from Sc3+ to Pr3+ activator centres was con firmed.

Zounková, Irena ; Kučera, Miroslav (advisor) ; Jandová, Dobroslava (referee) ; Mrzena, Bohuslav (referee)
Title: Timely diagnosis of motor function in children with intrauterine growth retardation and possibilities for its influencing with the aid of physiotherapeutic methods This dissertation focuses on the examination of children with locomotive coordination disorder that were born with the risk of intrauterine growth retardation (IUGR) in their case history. This work calls attention to notable postural deviations in the 5 th week of life of children that affect their motor development in the first year of life and could be a risk indicator for the emergence of postural deviations typical for children's defective posture (VDT). Aim: to confirm the methodological practice when assessing qualitative indicators of the most serious deviations of locomotive manifestations from physiological development of movement in the 5 th week of a child's life with the aid of developmental kinesiology. To confirm the effectivity of physiotherapeutic methods applied at an early age of the neonate. To emphasize the necessity of timely initiation of physiotherapy before the 3 rd month of a child's life within the framework of complex care for children with the risk of IUGR in their case history. Task: to evaluate the development of symptoms of postural deviations in the first four months of a child's life. To assess...

Škopek, Martin ; Kračmar, Bronislav (advisor) ; Kučera, Miroslav (referee) ; Jandová, Soňa (referee)
The Dissertation is concerned with monitoring of changes regarding muscle involvement in specific areas of human motion system when walking and Nordic walking (NW) with focus on adults and by means of electromyography method. Within the process of field testing there were 9 randomly selected individuals at the age of 50 - 60 tested to elicit differences in the motion system. There was an effort to find certain differences within involvement of specific muscle groups in the area of shoulder girdle, pelvic girdle and lower limbs and retrieval of similarities of coordination attributes concerning locomotion at horizontal presented by paradigm of kinesiological content of reflexive crawling according to Vojta's principle. Kinematic analyses was used to discover a difference in involvement of specific muscles between Nordic (v = 5 kph) and regular walking (v = 4, 75 kph) up to 10˚ of ascent. Muscles where their MVC was diagnosed the difference in individual muscle involvement was monitored expressed in percentage. The values found were consequently related to their referential value of MVC and tested by means of Wilcoxon test for dependent selection. Muscles where MVC value was not diagnosed the intraindividual comparative analyses of activation muscle pair similarity was carried out on the grounds of...

Praha 2012 1 MARTIN PIVEC 2012 Autoreferát disertační práce 1. Úvod Tento autoreferát k disertační práci s názvem "Hluboký stabilizační systém páteře stimulovaný Vojtovou reflexní lokomocí mění průběh klidového dýchání" podává souhrné informace především o experimentální části práce.. Teoretická východiska jsou detailně popsána v práci samotné 2.Cíle práce Utřídit poznatky o regulaci dýchání a o vlivu RL na dýchání Potvrdit, či vyvrátit vliv reflexní lokomoce na respiraci u zdravých jedinců Navrhnout možnosti objektivizace vlivu RL na dýchání 3. Teoretická východiska Zatímco lékařská věda se zabývá zejména průtokem vzduchu uvnitř dechových cest, fyzioterapeutický pohled se touto fází zabývá i z hlediska pohybového projevu. Roztažení plicních laloků je z fyzikálního principu zajištěno zvětšením objemu dutiny hrudní a ten je možno zvětšit pouze svalovou aktivitou. Jedním z prvních kdo upozornil na skutečnost, že řízení motoriky svalů je nedílnou, ba dokonce možná významnější, součástí fyziologie respiračního systému byl Plum v práci Cerebral control...
