Popular Abstract in Swedish Många sjöar i Sverige och i andra delar av den norra hemisfären blir allt brunare. Detta beror på att mer färgat organiskt material (humösa ämnen) sköljs ut från den omkring liggande marken och transporteras sen in i sjöarna. I min avhandling har jag undersökt om detta leder till att det blir mörkare i sjöarna, och hur detta i så fall påverkar växtplankton, dvs. små mikWater colour is currently increasing in thousands of lakes in the northern hemisphere due to an increased input of terrestrial dissolved organic carbon (DOC), and more specifically coloured disscolved humic matter (DHM). I studied how water colour affects the light climate in the epilimnion and, as a consequence, phytoplankton biomass, species composition and production in lakes in southern Sweden

I analyze the relation between rules of thumb and the actual corrrect language use. The idea is that a rule of thumb would be too complicated to be of any pactical value if it should really describe corect language. The examples are from Swedish language cultivation.

In the indoor environment there are a number of materials with potential to act as moisture buffers including both building materials and furnishing materials. For daily moisture variations in the indoor air furniture with upholstery can play an important role as moisture buffers. Material properties and calculation models describing the response to moisture variations in the ambient climate for t

We have characterized 2 distinct mechanisms through which infectious agents may promote platelet adhesion and thrombus formation in flowing blood, thus contributing to the progression of disease. In one case, the process initiates when the integrin alpha(IIb)beta(3) mediates platelet arrest onto immobilized bacterial constituents that have bound plasma fibrinogen. If blood contains antibodies agai

Worries about sleep, negative expectations of sleep, and frustration about sleep loss are assumed to play an important role in the development of insomnia. Eight items designed to measure aspects of vicious cycles of sleeplessness (VCS), on which insomnia patients and controls were found to differ in an earlier study, were used to form a new VCS scale. A sleep questionnaire including the VCS scale
