BACKGROUND: Preterm birth remains the major risk factor for the development of intraventricular hemorrhage, an injury that occurs in 25% of very low birth weight infants. Intraventricular hemorrhage is thought to be venous in origin and intrinsic thromboses in the germinal matrix are likely to play a triggering role. Antithrombin, a glycoprotein synthesized in the liver, is the major plasma inhibi

We study inhomogeneous random graphs in the subcritical case. Among other results, we derive an exact formula for the size of the largest connected component scaled by logn, with n being the size of the graph. This generalizes a result for the "rank-1 case". We also investigate branching processes associated with these graphs. In particular, we discover that the same well-known equation for the su

Relict spinel grains (similar to 25-250 mu m in diameter) from decomposed extraterrestrial material in Archean to Recent sediments can be used to reconstruct variations in the flux of different types of meteorites to Earth through the ages. Meteorite falls are rare and meteorites weather and decay rapidly on the Earth surface, making it a challenge to reconstruct ancient fluxes. Almost all meteori

In modern standard Swedish genitive is marked by -s, which, according to the standard analyses, is a phrasal clitic, viz. [mannen på gatan]s åsikt (man on street-s opinion). In dialects in parts of Småland, Halland, and Västergötland a variant on -a or -e, here called a-genitive, is used, primarily on proper names, viz. Erik-a bil (Erik-gen car) ‘Erik’s car’, a form that should be compared to the

Popular Abstract in Swedish Östersjön är idag ett av världens största innanhav med endast marginellt utbyte av vatten med Kattegatt via Öresund samt Lilla och Stora Bält. Saltrika inflöden från Kattegatt orsakar två salthaltsgradienter, en horisontell med mer saltrikt vatten i sydväst och mer färskt i Bottenhavet, samt en vertikal saltgradient (haloklin) med mer saltrikt bottenvatten och mer färskThe Baltic Sea is one of the world’s largest brackish water environments and is today suffering from, for example, eutrophication, spreading hypoxia, accumulations of contaminants and invasive organisms. These problems exist due to a combination of natural features that makes the Baltic Sea a sensitive ecosystem (such as long water residence time, limited water exchange, large catchment area), and

Popular Abstract in Swedish En god näringstillförsel är viktigt för att ett barn ska växa och utvecklas tillfredställande. De första 2-3 åren innebär en kraftig tillväxt och optimalt kostintag är därför extra viktigt under denna perioden. Barnets vikt tredubblas först året och längden ökar med 50 %. Hjärnan har en kraftig tillväxt de första 3 åren. Således är näringsbehoven relativt sett störst deThe overall aim of this thesis was to describe the prevalence of iron deficiency (ID) and factors influencing iron status and iron intake among otherwise healthy children. The specific aim in paper I+II was to describe the prevalence of ID among 2 ½-year-old children in relation to intake of cow's milk and follow-on formula. The design in the first two papers were cross-sectional and 367 2 ½-year-

Popular Abstract in Swedish Skogen utgör en viktig del av kolbalansen mellan mark och luft och har en potential att reducera koncentrationen av koldioxid i atmosfären. Mängden bladyta i en skog ger en indikation på skogens förmåga att binda koldioxid till marken. Den här avhandlingen utforskar möjligheterna att erhålla information om skogars mängd av bladyta med hjälp av den information som registThis thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. The results of the present studies indicate that some methods commonly used as a reference for more complicated methods could result in
