We have generated attosecond pulse trains in an ensemble of randomly aligned nitrogen molecules. Measurements of the high-order harmonic relative phases and amplitudes allow us to reconstruct the temporal profile of the attosecond pulses. We show that in the considered spectral range, the latter is very similar to the pulse train generated in argon under the same conditions. We discuss the possibl
A pool of heparan sulphate-binding proteins (HSBPs) from Helicobacter pylori culture supernates was obtained by sequential ammonium sulphate precipitation and affinity chromatography on heparin-Sepharose, The chromatographic procedure yielded one major fraction that contained proteins with heparan sulphate affinity as revealed by inhibition studies of heparan sulphate binding to H. pylori cells. P
Two novel human papillomaviruses (HPVs), HPV93 and HPV96, with genomes of 7450 and 7438 bp, respectively, are described. The Ll open reading frame of HPV93 showed highest identity to HPV24 (79%) and that of HPV96 had highest identity to HPV92 (71 %). Real-time PCR for HPV92, 93 and 96 on stripped biopsies from tumours and healthy skin from 269 immunocompetent patients found HPV DNA in 2.6 % of tum
Popular Abstract in Swedish Den kontinent Skandinavien idag tillhör kallas Eurasia, men den kontinent vi ser idag har inte alltid funnits. Kontinenterna var inte bara sammanfogade på andra sätt, de har också rört sig över jordens yta (de långsamma med samma hastighet som naglar växer!), i platt-tektoniska processer. Innan uppkomsten av Eurasia har Skandinavien i omgångar tillhört andra konstellatiIn an attempt to reconstruct the pre-Caledonian cratonic margin of Fennoscandia, U-Pb geochronological and geochemical investigations have been performed on allochthonous orthogneisses in the northern Swedish Caledonides. The crystalline basement of the nappes have also been examined to further constrain the continuation of various chronologically defined orogenic belts. To constrain the global pa
Angiogenesis is a prognostic indicator in primary breast cancer regulated by specific angiogenic factors and their receptors. Vascular endothelial growth factor-A (VEGF-A), so far considered the most important, acts through dimerization of the receptor VEGFR2/KDR within the receptor tyrosine kinase family of VEGF receptors. In order to study the interplay between VEGF-A and VEGFR2/KDR in breast ca
I rapporten beskrivs byggnadsfysikaliska mätningar i ett provhus med olika skalmurskonstruktioner. Mätningar har pågått under en 3-årsperiod och främst varit inriktade på fukt- och temperaturbetingelser i murverket, luftspalten, isoleringen och träreglarna.
Essä om författarens arbete med att restaurera och rekonstruera G W Pabsts stumfilmsklassiker Den glädjelösa gatan (Die Freudluse Gasse, 1925) och hur det påverkat synen på filmens historia och utveckling av berättartekniken.
The first results from the stopped beam RISING experimental campaign performed at the GSI laboratory in Darmstadt, Germany, are presented. RISING (Rare ISotope Investigations at GSI) constitutes a major new experimental program in European nuclear structure physics research aimed at using relativistic energy (typically around 1 GeV per nucleon) projectile fragmentation reactions to populate nuclei
OBJECTIVES: To analyse survival rates and the causes of death in a systemic sclerosis (SSc) population, and to evaluate the occurrence of fatal malignant neoplasms and their possible association with oral cyclophosphamide (CYC) treatment. METHODS: Survival was calculated for 249 SSc patients followed up for up to 13 years. Mean (SD) follow up was 5.8 (4.2) years. The 49 decreased patients were sub
Pancreatic islets have a central role in blood glucose homeostasis. In addition to insulin-producing beta-cells and glucagon-secreting alpha-cells, the islets contain somatostatin-releasing delta-cells(1). Somatostatin is a powerful inhibitor of insulin and glucagon secretion(2). It is normally secreted in response to glucose(3) and there is evidence suggesting its release becomes perturbed in dia
The thesis concerns risk and safety in manufacturing companies in a developing country. Risk and safety is viewed as integral to the social relations between management and labour. The Malaysian case presents a historical conjuncture of this conflict theme, which is very different from that of its Western genesis. On this basis, the primary objective of the thesis is defined as an effort to escape
The pheromone-mediated upwind flight of male turnip moths was observed in a flight tunnel at different times of day under conditions of a light-dark (LD) cycle, constant darkness (DD), and a shifted photoperiod. Under both LD and DD conditions, a significantly larger number of males flew to the pheromone during both the scotophase and the subjective scotophase than during the photophase and the su
