  1. 1. Recurrent Headache among Swedish Adolescents : Psychosocial Factors, Coping and Effects of Relaxation Treatment

    Författare :Åsa Fichtel; Huda Huijer Abu-Saad; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nursing; headache; adolescents; coping; relaxation; Omvårdnad; Nursing; Omvårdnad; Caring Sciences; omvårdnadsforskning med samhällsvetenskaplig inriktning;

    Sammanfattning : Overall aims of the present thesis were to study the prevalence and psychosocial impact of recurrent headache within a school population in comparison with other types of pain and to examine the use and efficacy of various coping strategies. Further aims were to compare the effects of relaxation treatment among adolescents with recurrent headache to a waiting-list control group, and finally to examine the efficacy of relaxation training administered in a school setting.

    Sammanfattning : A considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. LÄS MER

  4. 3. Static and Dynamic Correlation Effects in Atoms

    Författare :Nils-Erik Dahlen; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic and optical properties; electrical; Condensed matter:electronic structure; relaxation; magnetic resonance; supraconductors; spectroscopy; Kondenserade materiens egenskaper:elektronstruktur; Atom- och molekylärfysik; Atomic and molecular physics; spektroskopi; magnetisk resonans; egenskaper elektriska; supraledare; magnetiska och optiska ; variational energies; double ionization; Electron correlation; laser-atom interaction; Fysicumarkivet A:2002:Dahlen; conserving approximations; Green s functions; GW-approximation;

    Sammanfattning : The thesis considers the effects of electron correlation by studying the two opposite limits of atoms in the ground state and atoms in strong laser pulses. Computational methods and theoretical approaches differ significantly due to the different physical processes that are studied in these two cases. LÄS MER

  5. 4. Probing Dynamics of Oligosaccharides by Interference Phenomena in NMR Relaxation

    Författare :Leila Ghalebani; Jozef Kowalewski; Norbert Mueller; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NMR; sugars; oligosaccharides; carbon-13 relaxation; cross-correlated relaxation; molecular dynamics; internal motion; random jumps; PRE; paramagnetic relaxation; Chemistry; Kemi; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Oligosaccharides (carbohydrates) are a large class of biological molecules that are important as energy sources in the human body and have enormously varied biological functions. It is generally believed that biological activities of carbohydrates are related to their internal dynamics. LÄS MER

  7. 5. Relaxation and Resonance in Brownian Motion-Coupled Resonators

    Författare :Christin Rhen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nonequilibrium dynamics; nonlinear dynamics; resonance; nanomechanics; relaxation; superconducting circuits.; resonator; dispersive coupling; noise; Brownian motion;

    Sammanfattning : In physics, there exists a number of paradigm systems – exactly solvable models that can represent a wide variety of physical realizations. My research is concerned with two of these paradigm systems: the harmonic oscillator and Brownian motion. LÄS MER
