  2. 1. Central pain in multiple sclerosis : clinical characteristics, sensory abnormalities and treatment

    Author : Anders Österberg; Per Hansson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : In the present research programme the occurrence of pain in MS was investigated, with special emphasis on central pain (CP). Questionnaires were sent to all 429 patients with definite MS in the patient register at our neurology department. READ MORE

  4. 2. Microwave-assisted transformations of lignin for value-added material applications

    Author : Jenevieve G. Yao; Minna Hakkarainen; Karin Odelius; Monika Österberg; KTH; []
    Keywords : lignin; microwave-assisted processes; organosolv fractionation; esterification; fused filament fabrication; digital light processing; lignin; mikrovågsassisterade strategier; organosolv-fraktionering; förestring; additiv tillverkning; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The chemical diversity and structural complexity of lignin, an abundant biopolymer found in vascular plants, present a multitude of opportunities for the modification and fine-tuning of its properties to suit downstream demands. In this thesis, microwave-assisted strategies were explored as efficient and environment-friendly pathways for lignin valorization towards value-added material applications. READ MORE

  5. 3. Searches for Massive Highly Ionising Particles at the ATLAS Experiment and in Polar Volcanic Rocks, and Performance Studies of the First Level ATLAS Trigger System

    Author : Katarina Bendtz; David Milstead; Kenneth Österberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetiska monopoler; Trigger; fysik; Physics;

    Abstract : The Standard Model (SM) of particle physics describes the elementary particles and their interactions. Despite passing a number of high precision falsification tests, it is argued that the SM suffers from a number of shortcomings. Many Beyond the Standard Model (BSM) theories have therefore been postulated. READ MORE

  6. 4. Enabling Time- and Mission-Critical Applications in Industrial Wireless Sensor Networks

    Author : Hossam Farag; Mikael Gidlund; Patrik Österberg; Shaofang Gong; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Nowadays, Wireless Sensor Networks (WSNs) have gained importance as aflexible, easier deployment/maintenance and cost-effective alternative to wired networks,e.g., Fieldbus and Wired-HART, in a wide-range of applications. READ MORE

  7. 5. Backward and Forward Nonlinear Optical Processes in Potassium Titanyl Phosphate

    Author : Kjell Martin Mølster; Fredrik Laurell; Valdas Pasiskevicius; Ulf L. Österberg; Stefano Taccheo; KTH; []

    Abstract : Second-order nonlinear optical processes generate radiation across a broad spectrum, including UV and the far-infrared. In this thesis, new light sources in the near(NIR) and mid infrared (MIR) using three-wave mixing geometries in periodically poled potassium titanyl phosphate (PPKTP) is studied. READ MORE
