The demand for energy efficient heating solutions can be met by a new concept technology of induction heating. The concept technology relies on inductors built on litz wires moulded in soft magnetic composite. The aim of this article is to present and verify a hypothesis for greatly improved induction heating efficiency when modifying a traditional inductor design. The verification performed using

The maritime expansion of Scandinavian populations during the Viking Age (about ad 750–1050) was a far-flung transformation in world history1,2. Here we sequenced the genomes of 442 humans from archaeological sites across Europe and Greenland (to a median depth of about 1×) to understand the global influence of this expansion. We find the Viking period involved gene flow into Scandinavia from the The maritime expansion of Scandinavian populations during the Viking Age (about ad 750–1050) was a far-flung transformation in world history1,2.

The paper presents the results of a comparative analysis of machinability and dynamic stability when turning a nickel-based superalloy with WRA tools in a conventional and prototype toolholders. The use of the prototype toolholder with a spatial structure is shown to significantly suppress vibrations during the machining and stabilize the process within the cutting speed range between 200 and 400

During the last decades, the distribution and abundance of many European species of birds, plants and insects in agricultural landscapes have declined due to agricultural intensification. To be able to mitigate these declines, it is essential to know the relative importance on local and regional ecological processes on population persistence and patterns of species richness. I have studied the ef

The purpose of this thesis is to study how fairy tales can change when they are removed from one set of surroundings to another. This movement can occur on several levels; from an orally spoken to a written text, from a rural proletariat to an urban bourgeoisie. The point of departure has been the fairy tale collector and fairy tale writer Eva Wigström (1832-1901) who in the 1880s wandered through

Self-reported annoyance from electrical equipment has been in evidence since the mid-eighties, and the first reports of illness from everyday chemicals arose already in the 1960?s. However, the extent of the problem or the mechanisms behind the development of environmentally related annoyance has not yet been fully established. Increased vulnerability to stress has been suggested to be a possible

The phenomenon of stress is often illustrated by means of the demand-control-support model, a model that has inspired many research efforts in the area of psychosocial work environment. According to the model, work that is characterised by high demands, low decision latitude and low social support affects aversively health and well-being. Work control and social support may on the other hand act a

This work was aimed at improving our understanding of the course of primary Sjögren's syndrome (SS). The Malmö SS patient register and the 2002 American-European Consensus Criteria formed the basis of all studies. Helicobacter pylori (H. pylori) was not more prevalent in SS patients or associated with severe glandular or immunological dysfunction. Consequently, our results do not support screenin

The primary ambition of this doctoral thesis is to provide an empirical basis for a better understanding of reading disability among school children. The current consensus in the research community is that most disabled readers fail in the acquisition of fast, accurate and automatic word recognition. The thesis includes a number of studies where normal and disabled readers are compared on various
