  2. 1. Theoretical Investigations of C–O Activation in Biomass

    Author : Pemikar Srifa; Joseph Samec; Supa Hannongbua; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DFT calculations; global minima hopping; reactive force field; lignin; palladium; nucleophilic substitution; organisk kemi; Organic Chemistry;

    Abstract : This thesis focuses on using computational chemistry approaches to study how biobased molecules interact with both homo- and heterogeneous catalysts. The reaction mechanisms of such transformations have also been studied. READ MORE

  4. 2. Asymmetric lateral loading of the human trunk

    Author : Qiang-Min Huang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Eccentric; concentric; isokinetic; electromyography; co-activation; trunk; spinal biomechanics; contraction patterns; lateral bending; lifting and lowering; balance; kinematics; postural control; IAP; support translation.;

    Abstract : The overall aim of this thesis was to characterize the biomechanics and neuromuscular control of the human trunk in response to asymmetric lateral loading. The pulling force and strength capacities as well as muscle activation patterns, trunk kinematics and postural balance in relation to lateral trunk flexion and loading were given special consideration.

  5. 3. Pain related aspects of neck muscle performance, functioning and psychosocial factors in individuals with cervical radiculopathy

    Author : Marie Halvorsen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : activity limitations;

    Abstract : Aim: The overall aim of the work presented in this thesis was to describe and explore pain-related aspects of neck muscle performance, functioning and psychosocial factors in individuals with cervical radiculopathy (CR). Methods: Participants were 157 patients with CR. Also Study II included 33 asymptomatic age-and gender-matched controls. READ MORE

  6. 4. Triggering and mechanisms of natural killer cell mediated cytotoxicity

    Author : Yenan Bryceson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Natural killer cells; antibody dependent cellular cytotoxicity; natural cytotoxicity; immunodeficiency; hemophagocytic lymphohistiocytosis;

    Abstract : Natural killer (NK) cells are innate immune cells that contribute to defense against infected and transformed cells by target cell killing and cytokine release. In addition, data suggest that NK cells contribute to immune homeostasis and reproduction. READ MORE

  7. 5. Sagittal plane knee motion during activity in the anterior cruciate ligament deficient knee

    Author : Joanna Kvist; Alf Thorstensson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : A complete rupture of the anterior cruciate ligament (ACL) results in static and often in functional instability. After an ACL-injury, most patients have to decrease their activity level, while some can cope with their injury and manage to keep a high activity level. READ MORE
