Rapid climate warming has resulted in shrub expansion, mainly of erect deciduous shrubs in the Low Arctic, but the more extreme, sparsely vegetated, cold and dry High Arctic is generally considered to remain resistant to such shrub expansion in the next decades. Dwarf shrub dendrochronology may reveal climatological causes of past changes in growth, but is hindered at many High Arctic sites by sho
Rapporten är ett resultat av ett forskningsprojekt ”Fornsaker med landskapsarkeologiska perspektiv på Kullen” finansierat av Gyllenstiernska Krapperupstiftelsen 2015-2016. Det övergripande syftet var att beskriva och analysera fornsakssamlingen på Krapperup med avseende på föremålstyper, fyndplatser och fyndomständigheter. Accessionen av föremål skedde på initiativ baronen Carl Gyllenstierna främs
OBJECTIVE: To explore and quantify the relative strengths of the genetic contribution vs the contribution of modifiable environmental factors to severe osteoarthritis (OA) having progressed to total joint arthroplasty.DESIGN: Incident data from the Norwegian Arthroplasty Registry were linked with the Norwegian Twin Registry on the National ID-number in 2014 in a population-based prospective cohort
OBJECTIVE: To explore factors related to hand pain in persons with radiographic hand osteoarthritis (OA).METHODS: Persons in the Musculoskeletal Pain in Ullensaker Study with radiographic hand OA (≥1 joint with Kellgren/Lawrence grade ≥2) were included (n = 530). We examined the cross-sectional association between possible explanatory variables and hand pain in the entire sample and in 2 hand OA p
BACKGROUND: Widespread musculoskeletal pain (WSP) and obesity frequently co-occur and may have shared risk factors. We aimed to investigate whether four dichotomized risk factors individually or jointly increase the risk for the onset of WSP and onset of obesity.METHODS: Persons aged 34-76 years in 2004 living in Ullensaker municipality, Norway, responded to questionnaires in 2004 and 2010 (n = 15
Background: Production of second-generation bioethanol and other bulk chemicals by yeast fermentation requirescells that tolerate inhibitory lignocellulosic compounds at low pH. Saccharomyces cerevisiae displays high plasticitywith regard to inhibitor tolerance, and adaptation of cell populations to process conditions is essential for reachingefficient and robust fermentations.Results: In this stu
Mining, seen as a source of revenue in most developing countries, threatens seriously the environment. Mining impacts the water quality and one of the main problems of mining is acid mine drainage. Low pH and high concentration of heavy metals characterize acid mine drainage. When a stream is impacted by acid mine drainage both human activities and the ecological system are seriously affected. In
Successful fracture repair is a complex series of coordinated processes leading to regeneration of new bone to bridge the fracture site, remodelling of the newly formed bone and restoration of skeletal function. Disruption of these processes occurs in approximately 10% of all fractures and leads to delayed or failed healing requiring surgical interventions, increased complication rates, prolonged
Hydrodynamics and mass transfer in liquid-liquid slug flow inside a square microchannel (MC-1, aspect ratio 1) and a rectangular microchannel (MC-2, aspect ratio 2) with identical hydraulic diameter (400 µm) were investigated experimentally. The results showed that the overall volumetric mass transfer coefficient (KLa) in MC-2 was 16.2% lower than that in MC-1 due to enlargement of the dispersed p
Mitochondria are known for their role in ATP production and generation of reactive oxygen species, but little is known about the mechanism of their early involvement in plant stress signaling. The role of mitochondrial succinate dehydrogenase (SDH) in salicylic acid (SA) signaling was analyzed using two mutants: disrupted in stress response1 (dsr1), which is a point mutation in SDH1 identified in
