The Davies transformation is a method to transform the steering vector of a uniform circular array (UCA) to a vector with Vandermonde form. As this form is similar to that of the steering vector of a uniform linear array (ULA), we can apply to UCAs the many tools that have been developed for ULAs. However, the Davies transformation can be highly sensitive to perturbations of the underlying ideal a

Popular Abstract in Swedish Vad arbetar en analytisk kemist med? Exempel på kemiska analyser är att en idrottsman ska dopingtestas eller att eventuella föroreningar i vattnet från en bäck ska bestämmas. Den analytiska kemistens problemställning är vanligtvis att identifiera (kvalitativ analys) och mäta upp (kvantitativ analys) innehållet i ett prov. Ofta är de intressanta ämneshalterna mycket lågaCapillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.

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
