Popular Abstract in Swedish Helicobacter pylori är en spiralformad Gramnegativ human-specifik patogen, som kan penetrera magsäckens slemlager och kolonisera epitelskiktet. H. pylori infektion är en högriskfaktor för utvecklandet av kronisk gastrit, magsår och ventrikelcancer. Både aktivt växande spiralformer av H. pylori och dess runda viloformer framkallar kronisk magkatarr (gastrit) i BALB/cA möHelicobacter pylori is a human pathogen strongly associated with chronic type B gastritis, peptic ulcer disease, gastric cancer and MALT lymphoma. Our aims were to establish a mouse model of H. pylori infection, to study pathogenesis of gastritis and gastric cancer and to investigate new treatment strategies in this model. Both spiral and coccoid forms of H. pylori strains 17874, 25 and 553/93 cau

Popular Abstract in Swedish I denna avhandling presenteras tillämpningar av separationsmetoden asymmetrisk flödes fältflödesfraktionering (AsFlFFF) på biologiska makromolekyler. Många svåra ord redan i den första meningen? Nedan följer en populärvetenskaplig sammanfattning, avsedd att ge ”hobby-vetenskapsmannen” en inblick i avhandlings-området. Här beskrivs kortfattat, den i avhandlingen utnyttjaAsymmetrical flow field-flow fractionation (AsFlFFF) is especially useful in the application to biological macromolecules due to the absence of a stationary phase in the separation channel. As a result no upper exclusion limit occurs and low shear forces affect the sample components. In addition, native condition, most suitable for the samples analysed, can be used since no consideration has to be

This paper consists of two, somewhat disparate parts. In the first part, some experiences of two years of fieldwork are summarized, concentrating, as the subtitle suggests, on the very heart of phonetic fieldwork: the encounters and interviews with the informants. As a result of the fieldwork, the project now has access to recordings from approximately 1300 speakers of more than 100 dialects of Sw

This paper contributes to an on-going conversation among scholars engaged in the critical peacebuilding research regarding the issue of agency by highlighting the central yet often neglected role of women agency in transitional justice processes. It takes as its point of departure the critical questions repeatedly posed: whose peace, what justice and for whom? Thus, the aim is to critically examin

New and innovative production equipment can be developed by introducing lightweight materials in modern day automotive industry production lines. The properties of these new materials are expected to result in improved ergonomics, energy savings, increased flexibility and more robust equipment, which in the end will result in enhanced productivity. Carbon composite materials are one such alternati

A new idea for generation of quadrature signals on chip is presented. The topology is based on a passive RC polyphase filter, where the resistive parts are made active by using inverters. The active filter combines quadrature generation, isolation, and gain without losing quadrature performance compared to a regular RC polyphase filter. The filter technique is demonstrated in a 10GHz front-end app

Popular Abstract in Swedish Många av de föreningar som utvecklas i den farmaceutiska industrin idag har sina rötter i naturprodukter. Paclitaxel, den aktiva substansen i läkemedlet Taxol, återfinns bland annat i idegranens bark. Detta upptäcktes i början av 1960-talet då ett nationellt sökprogram för att finna nya naturprodukter för användning mot cancer organiserades i Amerika. Den låga halten avMany of the drugs that are developed in the pharmaceutical industry have their origin in natural products. Paclitaxel, the active substance of the medicine Taxol, was found in the bark of the Pacific yew tree (Taxus brevifolia). This was discovered in the early 1960's when a screening program was initiated by the National Cancer Institute (NCI) in the US, with the aim to find new natural products

Future historians might remember the period 2009-2012 as a turning point in the political response to global warming and climate change. The 1980s were a time of agenda-setting in which climate change became accepted as a political problem; the 1990s saw the first institutionalization through adoption of the United Nations Framework Convention on Climate Change in 1992 and its Kyoto Protocol in 19
