Abstract in UndeterminedThis article discusses the background to the erection of the huge church tower in Bjälbo, Östergötland, Sweden. Bjälbo, today a small rural village,was once the seat of one of the most powerful families in medieval Sweden. The erection of a church tower in Bjälbo probably served several purposes; shelter, dwelling, belfry and storehouse. The tall tower was also a grand symb
Platelet-derived growth factors (PDGFs) belong to the PDGF/VEGF (vascular endothelial growth factor) family of growth factors. Members of this family share a common structural feature, a conserved PDGF/VEGF homology domain, containing eight invariant cysteine residues. PDGFs form disulphidelinked dimers and exert their biological functions by binding to, and activating two receptor tyrosine kinase
Länge har teknikfrågorna uppmärksammats när det gäller energieffektivisering. Beteendefrågorna har kommit i skymundan, eftersom effektiviseringspotentialerna bedömts mycket stora med mera energieffektiv teknik. De senaste årens forskning kring människors energibeteende har visat på mycket stora variationer i energibeteende mellan olika typer av hushåll och olika individer. Samtidigt kan man konsta
In this grounded theory study, the authors interviewed caregivers andpatients in end-of-life cancer care and found Balancing to be a fundamentalprocess explaining the problem-solving strategies of most participants and offering a comprehensive perspective on both health care in general and end-of-life cancer care in particular. Balancing stages wereWeighing— sensing needs and wishes signaled by pa
The dissertation outlines the ideas behind Torsten Fogelqvist's (1880-1941) ambitions as a publicist for Dagens Nyheter and as a public educator. The study also seeks to do justice to a forgotten, or at least not exhaustively analysed, discussion, during the first four decades of the last century, and deals with education, humanism, modernity, cultural heritage, the role of the press and anti-Nazi
A complex picture was shown to 12 subjects, and each subject was asked to describe it from memory. Their spoken descriptions were recorded, transcribed and segmented into intonation units (Chafe 1994). The transcripts were then qualitatively analyzed with respect to how the picture had been conceptualized. As a result, two different styles of description could be identified. Perceiving space was d
This paper considers a class of control problems where there is a need to find switching-sequences between different linear systems, as well as linear control laws, to minimize some quadratic cost function. An algorithm to optimize the switching sequences for a class of switched linear problems is presented. The algorithm searches for solutions which are arbitrarily close to optimal finding the op
The history of the Royal Physiographic Society in Lund during the years 1772-2006 is described.
Description and assessment of attitudes among young women--all living in villages near Shiraz, Iran--toward family, education, employment, marriage, gender relations, religion, politics, and US-Iran relations. Data derived from author's interviews in period 2001-2005.
This paper will address the effects of mixing low-calorific fuel in to a natural gas fuelled large size combined cycle plant. Three different biofuels are tested namely; air blown gasification gas, indirect gasification gas and digestion gas. Simulations have been performed from 0-100% biofuel natural gas mixtures. The biofuel impacts on the full cycle performance are discussed. Some more in-depth
In 1637 the Swedish Crown, encouraged by Dutch merchants, developed a plan to establish a colonial outpost in America to tap into profitable tobacco and beaver pelt trade. The same year the first cargo ships left Sweden and sailed westwards to claim their piece of America along the Delaware River. Although in many ways unsuccessful and short-lived (the colony collapsed in 1656), New Sweden became
