A composition is a vector of positive components summing to a constant, usually taken to be 1. Hitherto the research on compositional correlation has mainly focused on the correlation between the components of composition. This thesis is concerned with modelling the correlation between two compositions. We introduce a generalization of the Dirichlet distribution to simultaneously describe two co

OBJECTIVE: The initiating events in the onset of pancreatitis are poorly understood. Possible candidates may be endogenous ligands, acting on receptors within ductal, acinar or stellate cells, which have previously been shown to cause a systemic inflammatory response syndrome. The aim of this study was to investigate whether acute pancreatitis could be induced by heparan sulphate (HS)infused into

Fermentation of dietary fibers by colonic microbiota generates short-chain fatty acids (SCFAs), e.g., propionic acid and butyric acid, which have been described to have "anti-obesity properties" by ameliorating fasting glycaemia, body weight and insulin tolerance in animal models. In the present study, we therefore investigate if propionic acid and butyric acid have effects on lipolysis, de novo l

Archaeology, philosophy and rhetoric: A review and faculty opposition of Asgeir Svestads doctoral dissertation “Finn din egen filosof” (“Find your own philosopher”) presented at the University of Tromsø, Norway, February 2004. The dissertation critically examines an article by Lise Nordenborg Myhre and the doctoral dissertations by Johan Hegardt, Håkan Karlsson and Michel Notelid.

Konstnären, slöjdläraren och fornforskaren Nils Månsson Mandelgren (1813-1899) vars samlingar förvaras på Folklivsarkivet dokumenterade en mängd olika föremål med teckningar och akvareller. Artikeln handlar om milstolpar och vägvisare ur denna samling.

In this paper, new physical limitations on the extinction cross section and broadband scattering are investigated. A measure of broadband scattering in terms of the integrated extinction is derived for a large class of scatterers based on the holomorphic properties of the forward scattering dyadic. Closed-form expressions of the integrated extinction are given for the homogeneous ellipsoids, and t

INTRODUCTION: Complications after lumbar anaesthesia and epidural blood patch have been described in patients with congenital small spinal canal and increased epidural fat or epidural lipomatosis. These conditions, whether occurring separately or in combination, require magnetic resonance imaging for diagnosis and grading, but their clinical significance is still unclear.
