Applications of spectrally and spatially resolved NMR: induced anisotropy and phase transition in hydrogels; new relaxation probes for imaging
Bernášek, Karel ; Lang, Jan (advisor) ; Hanyková, Lenka (referee) ; Janisova, Larysa (referee)
Nuclear magnetic resonance is a non-invasive way to observe material properties on a molecular level. Magnetic resonance imaging is an important diagnostic tool in medicine. Molecules of several metabolites in muscle tissue show similar interactions as molecules partially oriented in orienting media. These interactions could provide new information about processes in vivo, this can serve for diagnostics of metabolism. New insight into the function is gained by observation of metabolites in orienting media. Observable anisotropic interactions in muscle tissue in vivo could be used for diagnostic purposes. Anisotropic NMR interaction of solvent as a new method for observation of phase transition of hydrogel with temperature change or change of solvent composition. Use of magnetic resonance imaging in slices to observe the collapse of polyacrylamide in water-acetone mixtures. Use of diffusion-weighted magnetic resonance imaging to observe phase transition of PNIPAM-based semi-interpenetrating polymer.
Performance development in decathlon

Title: Individual evolutions of performance in decathlon Objectives: The main aim of the thesis is to evaluate the dynamic and the evolution of performance six selected decathletes. We assessed few young decathletes, which competed in nonathlon because of their age, and the rest of the decathletes in decathlon during their athletic careers. Methods: This thesis occupies with qualitative research. Based on the analysis of selected documents we used the method of prediction and comparison. The main aim was to study athletic results of all selected decathletes. All of the performances were scored by IAAF scoring tables for combined events. We chose a few decathletes of different ages, the age range of our selected decathletes varies from 18 to 27 years old. Results: We found out that the biggest increase performance of decathlon results were when all our selected decathletes were beginning of their athletic careers. The only exception is Marek Lukáš, he did not achieved an increase until later. When they were adults, their increase slowed down. We found out that the contemporary decathletes have similar growth rate performance. Keywords: decathlon, track and field, efficiency, analysis
