  1. 1. Multiple sclerosis in Västerbotten county, northern Sweden

    Author : Peter Sundström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiple sclerosis; epidemiology; prevalence; incidence; onset symptoms; disability; sick leave; professional assistance; Epstein-Barr virus; and HHV-6;

    Abstract : One out of several distinguishing features of multiple sclerosis (MS) is the epidemiological variation of geographic distribution. Population-based studies on the prevalence and incidence of MS in Sweden have previously been performed only in Göteborg. Another feature of MS is the clinical variation between individuals.

  2. 2. Numerical optimization of pacing strategies in locomotive endurance sports

    Author : David Sundström; Mats Tinnsten; Peter Carlsson; Mikael Bäckström; Erik Bruun Simonsen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pacing strategy; optimization; numerical simulation; equations of motion; method of moving asymptotes; cross-country skiing; cycling; Farthållningsstrategi; optimering; numerisk simulering; rörelseekvationer; method of moving asymptotes; längdskidåkning; cykling;

    Abstract : This thesis is devoted to the optimization of pacing strategies in two locomotive endurance sports; cross-country skiing and road cycling. It has been established that constant pace and variable power distributions are optimal if purely mechanical aspects of locomotion are considered in these sports. READ MORE

  3. 3. Optimized Pacing Strategies in Cross-Country Skiing and Time-Trial Road Cycling

    Author : David Sundström; Mats Tinnsten; Peter Carlsson; John Rasmussen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; numerical simulation; equations of motion; MMA; cross-country skiing; cycling; Optimering; numerisk simulering; rörelseekvationer; MMA; längdskidåkning; cykling;

    Abstract : This thesis is devoted to the analysis and optimization of pacing strategies in cross-country skiing and time-trial road cycling. In locomotive sports, it is well known that variable pacing strategies using changes in the distribution of power output are beneficial when external forces vary along the way. READ MORE

  4. 4. Licence to drive : the importance of reliability for the validity of the Swedish driving licence test

    Author : Susanne Alger; Hanna Eklöf; Anna Sundström; Peter Nyström; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Driving licence tests; driver s licence; driving test; theory test; licensing test; interrater reliability; classification consistency; examiner agreement; classification accuracy; förarprov; körprov; kunskapsprov; reliabilitet; validitet; bedömare; didactics of educational measurement; beteendevetenskapliga mätningar;

    Abstract : Background: The Swedish driving licence test is a criterion-referenced test resulting in a pass or fail. It currently consists of two parts - a theory test with 65 multiple-choice items and a practical driving test where at least 25 minutes are spent driving in traffic. READ MORE

  5. 5. Environmental risk factors for the occurrence of multiple sclerosis

    Author : Martin Biström; Peter Sundström; Johan Hultdin; Jonatan Salzer; Kjell-Morten Myhr; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Multiple sclerosis; risk factors; epidemiology; case-control study; Human herpesvirus 6A; Human herpesvirus 6B; leptin; insulin; Epstein-Barr virus; vitamin D; Neurology; neurologi;

    Abstract : Background. Multiple sclerosis (MS) is an inflammatory and degenerative disease of the central nervous system that typically debuts around age 30. About 2.3 million people are affected in the world today, and besides trauma it is the most common cause of neurological disability among young adults in the western world. READ MORE
