Rapport. Fornsaker med landskapsarkeologiska perspektiv på Kullen

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

Genetic factors contribute more to hip than knee surgery due to osteoarthritis - a population-based twin registry study of joint arthroplasty

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

Diabetes is associated with increased hand pain in erosive hand osteoarthritis : data from a population-based study

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

Individual and joint effects of risk factors for onset widespread pain and obesity - a population-based prospective cohort study

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

Increased lignocellulosic inhibitor tolerance of Saccharomyces cerevisiae cell populations in early stationary phase

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

Sustainable Water Quality Monitoring for Developing Countries in the Context of Mining : Monitoring systems and modelling

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

The Anabolic - Anti-catabolic Paradigm of Augmenting Skeletal Regeneration: A Bone Quality Perspective

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 non-circular microchannels : Comparison of two aspect ratios and three junction structures

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

Salicylic acid-dependent plant stress signaling via mitochondrial succinate dehydrogenase

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

The transcription factor MYB29 is a regulator of alternative oxidase1a

Plants sense and integrate a variety of signals from the environment through different interacting signal transduction pathways that involve hormones and signaling molecules. Using ALTERNATIVE OXIDASE1a (AOX1a) gene expression as a model system of retrograde or stress signaling between mitochondria and the nucleus, MYB DOMAIN PROTEIN29 (MYB29) was identified as a negative regulator (regulator of a

Estimation of vertical displacement during ascending evacuation

This paper describes an ascending evacuation model based on physical work capacity, when exhaustion may play a key role during evacuation. The experiment was carried out on a stair machine (StairMaster, SM5, USA) which involved 13 male and 12 female subjects. Individual climbing speeds at 50 and 70 % of their maximal aerobic capacity (% VO2max) level (L1 and L2) were selected for 3 minutes, and 90

Perceived home is associated with psychological well-being in a cohort aged 67–70 years

Research on very old people has shown that perceived aspects of home are important for health, but research on such associations in younger cohorts of older people is lacking. The aim of this study was to investigate whether perceived aspects of home were associated with psychological well-being among community-living people aged 67–70. Interview data were collected with 371 individuals living in

Investigation of transient ignition process in a cavity based scramjet combustor using combined ethylene injectors

Large Eddy Simulation (LES) and experiment were employed to investigate the transient ignition and flame propagation process in a rearwall-expansion cavity scramjet combustor using combined fuel injection schemes. The compressible supersonic solver and three ethylene combustion mechanisms were first validated against experimental data and results show in reasonably good agreement. Fuel injection s

Concentration of perfluorinated compounds and cotinine in human foetal organs, placenta, and maternal plasma

Background Perfluoroalkyl substances (PFASs) are bio-accumulative pollutants, and prenatal exposure to PFASs is believed to impact human foetal development and may have long-term adverse health effects later in life. Additionally, maternal cigarette smoking may be associated with PFAS levels. Foetal exposure has previously been estimated from umbilical cord plasma, but the actual concentration in
