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

Simulations of collective effects in the MAX IV 3 GeV ring were done with the tracking code mbtrack. The code is a 6D macroparticle tracking code performing transformations under the influence of various wakefields. Each bunch is presented by a number of macroparticles which are sorted into bins according to their longitudinal position. The discrepancy in the results for the microwave instability

In the near future several astronomical observatories in Chile areplanning to use sodium laser guide stars to increase the sky coverageprovided by their adaptive optics facilities. Knowledge of themesospheric sodium layer behavior is crucial to predict the performanceof future laser guide star adaptive optics systems. Whereas the sodiumlayer has been observed quite extensively at several locations

This paper describes work in progress exploring influences of product form in design practice based on interviews with five industrial designers in southern Sweden. Participants were asked to list and compare different designers, and to explain how their respective characteristics affected product form. The findings indicate designers as shaped by traditions and acting not only to serve their clie

Popular Abstract in Swedish Brosk bekläder våra leder och förser dem med en slät yta vilket förhindrar en direkt ben mot ben kontakt. Det fungerar också som stötdämpare i belastade leder och ger glidytan mycket låg friktion. Vatten hålls kvar i broskets matrix på grund av den negativt laddade proteogykanen Aggrecan vilken i sin tur hålls kvar i ett nätverk av kollagenfibrer. När en led belastas prThe cartilage matrix is made up of a fibrillar meshwork comprising type II collagen and other associated proteins. One main function of this network is to retain the large aggregating proteoglycan, aggrecan, a vital component in the regulation of fluid flux in cartilage. In disease such as osteoarthritis, the breakdown of the collagen network appears to be the final step in destruction of cartilag

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
