Popular Abstract in Swedish Vissa E. coli bakterier kan vara utrustad med arvsanlag (gener) som kodar för vidhäftningsfaktorer, som gör att den kan binda till tarmslemhinnan, eller toxiner som kan orsaka olika typer av tarmsjukdom som diarré. En annan faktorer som kan bidra till att en bakterie kan orsaka infektion är genkassetter, som kodar för en rad av olika gener, som t.ex för upptag av järn, The presence of genes in food, encoding some virulence factors, was studied by PCR, and species of Enterobacteriaceae, associated with food, were studied by the DNA-based methods of TTGE, ribotyping and sequencing. The flora of fresh and chill-stored pork were analysed by a culture-independent approach, using specific amplification of 16S rRNA genes followed by cloning and sequencing. No evidence

This paper presents and discusses hitherto unexplored primary sources from the Spanish Civil War archive in Salamanca on the relations between the two largest anarcho-syndicalist organizations in the 1930s, namely Swedish SAC and Spanish CNT. The study shows how these organizations understanding and solidarity with each other,and discusses the traces the ideological contradictions of contemporary

Bioethical government advisory committees have profound influence on political decision-making on gene technology issues, concerning not only patients with genetically related diseases, but also, potentially, the whole society. • Decision-making on issues concerning all society should be democratically legitimate in all aspects, including the work of government advisory committees. • Democratic le

This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). The study in this thesis is restricted to a parallel hybrid vehicle equipped with a diesel engine, two electric machines

We present a pipelined implementation of an iterative threshold detector, which makes the same decisions as a maximum likelihood sequence detector (MLSD) on some, but not necessarily all, bits. We apply this as a first stage detector in a direct sequence code division multiple access (DS-CDMA) interference-limited multiuser system. In combination with the single-user matched filter (MF) detector w

Different aspects of cantilevers to be used as sensors have been studied. Silicon cantilevers have been fabricated and integrated on CMOS chips using low-energy electron beam lithography in order to reduce the irradiation damage to the circuits. The released and integrated cantilevers have been tested and used as mass sensors in air. The resonance frequency of the cantilever was measured before an
