  1. 1. Sagittal plane knee translation in healthy and ACL deficient subjects : a methodological study in vivo with clinical implications

    Författare :Anil Vergis; Jon Karlsson; Linköpings universitet; []
    Nyckelord :anterior cruciate ligament; electrogoniometer system; gait; knee; kinematics; motion analysis; step ascent; step descent; translation; MEDICINE; MEDICIN;

    Sammanfattning : This study on human subjects, comprises of four cross sectional and one prospective cohort study. The general purpose of this work was to develop a technique for measuring in vivo, sagittal anterior-posterior translatory motions in the knee joint using a computerized electrogoniometer (CA-4000, OS Inc., Hayward CA, USA).

  3. 2. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent

    Författare :Amitava Halder; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stair climbing evacuation; Physical work capacity; Physiological constraints; Endurance; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue; Incline gait biomechanics; Ground reaction forces; Required coefficient of friction;

    Sammanfattning : Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maximal aerobic capacity (V̇O2max).

  4. 3. Evaluation of physical work capacity and leg muscle fatigue during exhaustive stair ascending evacuation

    Författare :Amitava Halder; Ergonomi och aerosolteknologi; []
    Nyckelord :Stair climbing; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue;

    Sammanfattning : AbstractPhysical exhaustion can constrain human ascending work capacity and performance during emergency evacuation on stairs. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations during two different strategies: self-preferred pace in three different public stairways in the field, and controlled pace in a laboratory on a stair machine.

  5. 4. “Everything important is to do with passion” : Iris Murdoch’s concept of love and its Platonic origin

    Författare :Kate Larson; []
    Nyckelord :HUMANIORA; HUMANITIES; Murdoch; Weil; Plato; philosophy; art; love; eros; attention; decreation; unselfing; spiritual exercise;

    Sammanfattning : The object of this dissertation is to highlight the influence of Simone Weil and Plato on the philosopher Iris Murdoch. This is done through an investigation of her concept of love. The aim is to investigate the concept as it is portrayed in Iris Murdoch’s work with the claim to be a central, but as such neglected, concept in philosophy. LÄS MER

  7. 5. Metal film growth on weakly-interacting substrates : Stochastic simulations and analytical modelling

    Författare :Víctor Gervilla Palomar; Kostas Sarakinos; Georgios Almyras; Pär Olsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Thin films are nanoscale layers of material, with exotic properties useful in diverse areas, ranging from biomedicine to nanoelectronics and surface protection. Film properties are not only determined by their chemical composition, but also by their microstructure and roughness, features that depend crucially on the growth process due to the inherent out-of equilibrium nature of the film deposition techniques.
