  1. 11. Assessment of central auditory functions : methods and applications

    Författare :Mathias Hällgren; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Central auditory processing is complex and can not be completely evaluated by a single method. This thesis focuses on assessment of some aspects of central auditory functions by the use of dichotic speech tests, cognitive tests that tax functions important for speech processing and electrophysiological tests.

  3. 12. Bygden, bruket och samhället : Om människor och organisationer i brukssamhället Böksholm 1900-1979

    Författare :Åsa Lundqvist; Sociologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; sociology of enterprise; industrialisation; Sociology of labour; Social and economic history; patriarchalism; gender division of labour; local; central; agency; organisations; social movements; rural industrial community; historical sociology; industrial society; Arbetslivssociologi; företagssociologi; Ekonomisk och social historia; Sociologi;

    Sammanfattning : The aim of this dissertation is to study some of the forces behind the transformation of the 20th century industrialised countryside. The emphasis is on changes in everyday life for women and men, and the role of organisations therein. LÄS MER

  4. 13. Cyanide and central nervous system : a study with focus on brain dopamine

    Författare :Gudrun Cassel; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CNS; cyanide; dopaminergic system; convulsions; receptor binding; tyrosine hydroxylase; monoamine oxidase; extracellular release; inositol phosphate; GABA; GAD;

    Sammanfattning : The brain is a major target site in acute cyanide intoxication, as indicated by several symptoms and signs. Cyanide inhibits the enzyme cytochrome oxidase. This inhibition causes impaired oxygen utilization in all cells affected, severe metabolic acidosis and inhibited production of energy. LÄS MER

  5. 14. Human muscle spindles : complex morphology and structural organisation

    Författare :Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
    Nyckelord :human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy;

    Sammanfattning : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. LÄS MER

  7. 15. Quantum Chemical Studies of Radical Cation Rearrangement, Radical Carbonylation, and Homolytic Substitution Reactions

    Författare :Daniel Norberg; Nessima Salhi-Benachenhou; Sten Lunell; Tim Clark; Uppsala universitet; []
    Nyckelord :Quantum chemistry; quantum chemistry; coupled-cluster; density functional theory; meta-GGA; reaction mechanism; potential energy surface; isomerization; fragmentation; dissociation; condensation; addition; SH2; hydrogen abstraction; iodine atom transfer; complex; weakly interacting system; hyperfine coupling constant; Kvantkemi;

    Sammanfattning : Quantum chemical calculations have been performed to investigate radical cation rearrangement, radical carbonylation, and homolytic substitution reactions of organic molecules. The rearrangement of the bicyclopropylidiene radical cation to the tetramethyleneethane radical cation is predicted to proceed with stepwise disrotatory opening of the two rings. LÄS MER
