Popular Abstract in Swedish Populärvetenskaplig svensk sammanfattning Symptom från mag- och tarmkanalen som smärtor , diarrè, illamåande och blödningar är vanliga hos personer som missbrukar alkohol. Orsaken till denna typ av besvär är emellertid något oklart. Alkohol tas upp i blodet från magsäcken och övre delen av tunntarmen. Således kan alkohol ha effekter på slemhinnan i mag- och tarmkanalen.Background: Gastrointestinal symptoms such as dyspepsia, diarrhoea, and nausea are often seen in alcoholics. The causes are not clear. The stomach and upper small intestine are exposed to high alcohol concentrations. Yet, the majority of alcohol abusers do not exhibit macroscopic abnormalities at upper gastrointestinal endoscopy, although histological and electron microscopic (SEM) changes have be

Popular Abstract in Swedish Lunds strängfragmenteringsmodell beskriver hur färgade partiklar (kvarkar och gluoner, tillsammans kallade partoner) som produceras vid högenergetisk partikelkollisioner omvandlas till färgneutrala hadroner. Denna avhandling utvecklar och utforskar ett alternativt tillvägagångssätt till modellen. Den nya infallsvinkeln förbättrar modellen för system som består av många The Lund string fagmentation model was reformulated as a process along the boundary curve of the string called the directrix, in order to treat multigluon strings according to the Lund model area law. It was found that the hadrons in the final state could be collected into several groups, in such a way that the energy-momenta of the hadrons in a group lie in a plane in the Minkowski space within s

The chapter traces the development of the international response to the pandemic of HIV/AIDS from the designation of the World Health Organization (WHO) as “lead agency” in the late 1980s to the emergence of a variety of public-private partnerships from the 1990s onwards. This trajectory is related to general trends in global public health governance. Existing partnerships in the field of HIV/AIDS

In research on Birka strong focus has since long been directed towards long-distance contacts with Western as well with and Northeastern Europe (todays Russia, Belarus and Ukraine). The great attention paid to west- and east European contacts has likely contributed to that contacts with Finland have fallen out of the discussions. However as seen from studies of the pottery in Birka the Baltic Finn

Otoliths, or earstones, are small, biogenic concretions of aragonitic calcium carbonate precipitated on a protein matrix. Otoliths form part of the hearing and balance system in teleost fishes, and grow as the fish grow, providing a continuous biochronology of growth. Various elements are entrained in minor and trace quantities. In particular, strontium is a useful scalar of habitat use when varia

Lattice decoders for MIMO systems, including the sphere decoder (SD) and the Schnorr-Euchner (SE) decoder, have been shown to approach the performance of Maximum-likelihood decoder with low complexity. There are three kinds of lattice decoder, sequential SD, K-best SD and sequential SE, which are popular in the literature. As a modification to the K-best SD, a lower complexity K-best SE is propose
