The barium overabundances observed at the surface of barium stars originate from accretion long ago from the wind of a companion AGB star. However, this scenario cannot explain their high eccentricities and short orbital periods that have remained a mystery for decades. We investigate how kicks imparted to the white-dwarf at its birth or the presence of a circumbinary disk can solve this problem.
In this article we report on a systematic comparison of presentational sentencesin Icelandic and Swedish, looking in particular at possible thematicroles of the pivot and how they correlate with positional options. Despitesome well-known differences between the languages (only Icelandic allows‘high’ IP-pivots and pivots with transitive verbs), it turns out that the restrictionson VP-pivots are sim
HD 61396 has been identified as an X-ray and radio source and has shown Hα emission and photometric variability which have marked it out as an RS CVn star. Although it has been termed an RS CVn binary, hard evidence of its duplicity has been lacking. It is now shown to be a double-lined binary consisting of two giant stars, probably of almost equal size and luminosity but with a mass ratio of more
Paper on the film 'Chekovian Motifs' by Kira Muratova with the philosopher Michael Marder.
Intestinal mononuclear phagocytes, comprising macrophages (Mφs) and dendritic cells (DCs), play important roles in the generation and the regulation of immune responses to intestinal antigens, and alterations in the development and/or the function of these cells are thought to contribute to the pathogenesis of inflammatory bowel disease. In this review, we discuss the role of tumor necrosis factor
The typical acoustical treatment in ordinary rooms such as classrooms, offices, conference rooms etc is an absorbing suspended ceiling. Due to the non-uniform distribution of the absorbing material the sound field at steady-state and during sound decay is far from the ideal conditions assumed in the diffuse field theory. Especially during the sound decay, the degeneration of the sound field emphas

BACKGROUND: Temporal patterns of brain interstitial amino acids after subarachnoid haemorrhage (SAH) were studied in relation to energy metabolite levels and to the severity of the initial global ischaemia as reflected by the level of consciousness at admission.METHOD: Intracerebral microdialysis was used to measure brain interstitial amino acids and the energy metabolites glucose, lactate, and py
OBJECT: The aim of this study was to explore the relationship between hemodynamics (intracranial and systemic) and brain tissue energy metabolism, and between hemodynamics and glutamate (Glt)-glutamine (Gln) cycle activity.METHODS: Brain interstitial levels of lactate, pyruvate, Glt, and Gln were prospectively monitored in the neurointensive care unit for more than 3600 hours using intracerebral m
This randomized double-blind placebo controlled study assessed the vaginal colonization of lactic acid bacteria and clinical outcome. Vaginal capsules containing L gasseri LN40, Lactobacillus fermentum LN99, L. casei subsp. rhamnosus LN113 and P. acidilactici LN23, or placebos were administered for five days to 95 women after conventional treatment of bacterial vaginosis and/or vulvovaginal candid
