  1. 1. Prospective and longitudinal human studies of lead and cadmium exposure and the kidney

    Författare :Johan Nilsson Sommar; Ingvar A Bergdahl; Max Petzold; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cadmium; end-stage renal disease; kidney; lead; longitudinal; matched case-control; mixed effects; prospective; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Cadmium and lead accumulate in humans and can have toxic effects. Exposure to cadmium is well known to cause kidney damage. Cadmium binds to metallothioneins, proteins that play a role in cadmium transport. LÄS MER

  3. 2. Articulation Rate and Surprisal in Swedish Child-Directed Speech

    Författare :Johan Sjons; Mats Wirén; Robert Östling; Iris-Corinna Schwarz; Francisco Lacerda; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; articulation rate; information-theoretic surprisal; child-directed speech; final lengthening; spontaneous; longitudinal;

    Sammanfattning : Child-directed speech (CDS) differs from adult-directed speech (ADS) in several respects whose possible facilitating effects for language acquisition are still being studied. One such difference concerns articulation rate --- the number of linguistic units by the number of time units, excluding pauses --- which has been shown to be generally lower than in ADS. LÄS MER

  4. 3. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator

    Författare :Oskar Danielsson; Mats Leijon; Göran Engdahl; Uppsala universitet; []
    Nyckelord :Engineering physics; Finite element method; linear synchronous generator; longitudinal end effect; permanent magnet; point absorber; offshore testing; wave power; Teknisk fysik;

    Sammanfattning : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. LÄS MER

  5. 4. The effect of pressure afterload due to aortic coarctation on left ventricular function in children

    Författare :Haki Jashari; Michael Henein; Annika Rydberg; Katarina Hanséus; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coarctation of the aorta; congenital aortic stenosis; left ventricle; myocardial deformation imaging; speckle tracking echocardiography; longitudinal strain; aorto-septal angle; children; kardiologi; Cardiology;

    Sammanfattning : Background:Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV). Conventional treatment of native CoA is surgical repair, however potential recurrence or other related complications e.g. LÄS MER

  7. 5. Neck pain in women : effect of tailored treatment and impact of work environment

    Författare :Åsa Svedmark; Martin Björklund; Charlotte Häger; Jens Wahlström; Ottar Vasseljen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neck pain; neck disability; treatment; work exposure; stress; physiotherapy; fysioterapi;

    Sammanfattning : Introduction: Musculoskeletal pain is a common problem in the working population. In Sweden, 40% of women and 30% of men report suffering from neck and shoulder pain weekly. The underlying cause for neck pain is often not known and the treatment is commonly guided by the individual’s symptoms. LÄS MER
