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

The dramatic increase in demand for wireless Internet access has lead to the introduction of new wireless architectures and systems including 3G, Wi-Fi and WiMAX. 3G systems such as UMTS and CDMA2000 are leaning towards an all-IP architecture for transporting IP multimedia services, mainly due to its scalability and promising capability of inter-working heterogeneous wireless access networks. Duri

This paper presents a novel application which implements a way of adding sound breadcrumbs to the environment. We report results from initial user tests which suggest that this type of design could be useful for a wide range of mobile location based applications.
