  2. 1. Effects of Ageing and Physical Activity on Regulation of Muscle Contraction

    Author : Alexander Cristea; Lars Larsson; Anna-Stina Höglund; Ingrid Lundberg; Uppsala universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; ageing; sarcopenia; sprint training; progressive resistance training; in vivo function; isokinetic dynamometer; in vitro function; single permeabilised fibre; myonuclear domain; confocal microscopy; Medicine; Medicin;

    Abstract : The aims of this study were to investigate the mechanisms underlying (1) the ageing-related motor handicap at the whole muscle, cellular, contractile protein and myonuclear levels; and (2) ageing-related differences in muscle adaptability.In vivo muscles function was studied in the knee extensors.

  4. 2. Laboratory measurements of airborne emissions from car brakes for clean air

    Author : Guido Perricone; Ulf Olofsson; Fulvio Amato; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive brake; non-exhaust emissions; inertia brake dynamometer; airborne particles; PM10; PN; isokinetic sampling; Rebrake; volatiles; real driving cycle; car brake emission factors; running-in.; Bilbroms; icke-avgasemissioner; skivbromsdynamometer; luftburna partiklar; PM10; PN; isokinetisk provtagning; Rebrake; volatiler; verkliga körcykler; emissionsfaktorer; in-körning.; Machine Design; Maskinkonstruktion;

    Abstract : Brake systems are used to safely stop vehicles. The brake pads are pressed against the brake disc, transforming the kinetic energy of the vehicle into heat to be dissipated. READ MORE

  5. 3. Pharmacodynamics of low-dose clonazepam in children with epilepsy or spasticity : neurophysiological and clinical studies

    Author : Maria Dahlin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Children; epilepsy; spasticity; AED; clonazepam; seizures; electroencephalography; magnetoencephalography; dynamometer;

    Abstract : In children with epilepsy the evaluation of the efficacy of an antiepileptic drug (AED) is usually made by recording the seizure frequency. Some seizures are subtle and difficult to detect and epileptiform activity even without clinical seizures may cause cognitive dysfunctions. READ MORE

  6. 4. Velocity controlled dynamometry and gait analysis : development of methods and applications

    Author : Lennart Gransberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Dynamometry; torque; measurement error; overshoot; isokinetic; concentric; eccentric; gait analysis; three-dimensional; electrogoniometer; electromagnetic tracking;

    Abstract : The isokinetic systems developed in the present study can measure torque in maximal voluntary and passive movements. The torque recordings may be combined with surface EMG recordings from pairs of antagonistic muscles involved in the movement. Healthy subjects and patients with spastic paresis have been examined.

  7. 5. Aging effects on commercial lean NOx trap catalysts

    Author : Jesus De Abreu Goes; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aging; thermal degradation; sulfur poisoning; characterization; commercial lean NOx traps; NOx storage and reduction;

    Abstract : As a countermeasure to global warming, vehicles with low carbon emissions are being investigated by promoting lean-burn engines and high combustion efficiencies. However, one limitation to the increasing use of these engines is the need to develop corresponding catalytic systems for controlling the nitrogen oxide (NOx) emissions in their lean exhaust.
