  1. 21. Evolution of Plants : a mathematical perspective

    Författare :Magnus Lindh; Åke Brännström; Jacob Johansson; Mats G Larson; Lennart Persson; Claus Rüffler; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; plants; mathematics; optimization; optimal control; adaptive dynamics; flowering; seasons; tree crown; drought; taproot; trade-off; strategy; trait; ESS; NPP; LAI; Red Queen; Mathematics; matematik;

    Sammanfattning : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. LÄS MER

  3. 22. Electroencephalography for neurological prognostication after cardiac arrest

    Författare :Erik Westhall; Klinisk neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EEG; Interrater variability; Brain injury; Cardiac arrest; Hypothermia; Prognosis; Outcome;

    Sammanfattning : This thesis focuses on the prognostic value of electroencephalography(EEG) in comatose patients resuscitated after cardiac arrest (CA), using both simplified continuous EEG monitoring (cEEG) and routine EEG. Background: Comatose survivors are admitted to an intensive care unit (ICU) to support vital functions. LÄS MER

  4. 23. Radiotherapy in Early Breast Cancer

    Författare :Fredrika Killander; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pentoxifylline; cyclophosphamide; tamoxifen; side effects; randomised trial; Breast cancer; radiotherapy;

    Sammanfattning : Radiotherapy (RT) after mastectomy has been part of the treatment for early breast cancer since the 1940s. The treatment reduces the risk of loco-regional recurrences, but implies risk of late side effects that can begin decades after RT. LÄS MER

  5. 24. Twisted Loops and Models for Form-factors and the Muon g-2

    Författare :Johan Relefors; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chiral perturbation theory; Twisted boundary conditions; Phenomenological models; Muon g-2; Fysicumarkivet A:2016:Relefors;

    Sammanfattning : In this thesis we use effective field thory methods and models for low energy QCD in two different contexts. One is direct calculation of contributions to the anomalous magnetic moment of the muon, muon g-2. The other is estimates of systematic sources of uncertainty in lattice QCD simulations. The work is presented in five papers. LÄS MER

  7. 25. L68Q cystatin C: Expression, cellular transport and turnover of the cystatin C variant forming amyloid in patients with Hereditary Cystatin C Amyloid Angiopaty (HCCAA)

    Författare :María Bjarnadóttir; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cysteine proteinase inhibitor; brain haemorrhage; amyloid; cystatin C; HCCAA; Clinical chemistry; Klinisk kemi;

    Sammanfattning : Hereditary cystatin C amyloid angiopathy (HCCAA) is a disorder characterised by multiple strokes in young adults, resulting in paralysis and dementia. The disease is caused by a mutation in the gene coding for the peptidase inhibitor cystatin C. LÄS MER
