The motion of pre-existing edge dislocations in an infinite linear elastic body is studied. Motion is due to a quasi-statically steady-state growing crack. In the model, the dislocations glide if the force on the dislocation exceeds a critical value. Obtained results are changes in dislocation density, the shielding effect on the crack tip and residual stresses. The model is applied to an isotropi

We have measured critical supersaturations of dried single component particles of sodium caprylate (CH3(CH2)6COONa), sodium caprate (CH3(CH2)8COONa), sodium laurate (CH3(CH2)10COONa) and sodium myristate (CH3(CH2)12COONa), respectively, in the diameter range 33-140 nm at 296 K using a static thermal gradient diffusion cloud condensation nucleus counter. These fatty acid sodium salts are surface ac

Preindustrial society was characterised by vast uncertainties due to harvest failures and fluctuations in prices of basic commodities. These economic fluctuations had severe effects on the standard of living, especially for the poorer segments of the population, as shown for instance, by the increased mortality following economic crises. This article examines the extent to which migration could be

The content of this report is a Deliverable of the FP7 project RUFUS (Rural Future Networks) concerning the Swedish case studies that have been conducted within the project. Two regions in the south of Sweden – the counties of Kronoberg and Kalmar – have been studied in order to find out how social and economic development strategies are enacted in these rural regions. This report concerns Kronobe

The growing use of underground cables in distribution systems increases the capacitive coupling of the network to earth and as a consequence the capacitive earth fault current. In rural systems consisting of long cable feeders the extensive reactive current transportation gives rise to resistive losses that influence the earth fault protection. Simulations carried out in this work suggest the resi

Popular Abstract in Swedish En tredjedel av befolkningen i världens industrialiserade länder lider av allergi, t.ex. allergisk rinit (hösnuva). Trots detta vet man relativt lite om de cellulära och molekylära mekanismer som ligger till grund för det immunologiska svaret vid allergi. Genom att studera dessa mekanismer kan man hitta sätt att angripa dem, vilket förhoppningsvis kan leda till bättre lAllergic diseases currently affect a third of the population in the industrialized parts of the world. Despite this, the cellular and molecular mechanisms involved in the induction and activation of allergic diseases are not fully clarified. Dendritic cells (DCs) link the innate and adaptive immunity and play vital roles in protective immunity against pathogens, as well as in inducing tolerance t
