Icelandic declarative V1 : a brief overview

This squib is a brief state of the art overview of declarative V1 in Icelandic, old and modern. Three(relevant) types of such clauses are discussed: Narrative Inversion, with an overt topical subjectdirectly after the verb, Presentational V1, with an overt non-topical subject, and Null-subject V1.Narrative Inversion is a robust main clause phenomenon, whereas Presentational V1 and Null-subjectV1 a

Thermohaline mixing and the variation of [C/Fe] with magnitude in M3

We use observations of M3 to constrain thermohaline mixing. This is done by matching [C/Fe] and [N/Fe] along the RGB of M3. We find our models can explain observations if it is assumed there is a spread of ∼ 0.3 - 0.4 dex in [C/Fe] in the stars in M3 from their birth. We reproduce the full spread in [C/Fe] at the tip of the RGB. Thermohaline mixing can produce a significant change in [N/Fe] as a f

Barium stars revisited

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.

Presentational sentences in Icelandic and Swedish : Roles and positions

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 : An unusual mass-transfer RS CVn binary

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

Physiological Role of TNF in Mucosal Immunology : Regulation of Macrophage/Dendritic Cell Function

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

Optimization of sound absorbing ceilings

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

Temporal patterns of interstitial pyruvate and amino acids after subarachnoid haemorrhage are related to the level of consciousness--a clinical microdialysis study

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
