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.

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
