چکیده
rhage (SAH) due to rupture of a cerebral aneurysm is 10 per 100,000 per year. About 15% of patients who suffer a SAH will die before reaching hospital. Of the remainder, 25% will die in hospital and only 50% will make a full recovery. The risk of dying is highest during the first 24 h after haemorrhage, but remains significant for a further 2 months. Rupture can occur at any age but is most common in 50–60-year-olds. This is the age group where other co-morbid conditions may make anaesthesia more complex. The commonest co-morbid condition is essential hypertension which may be present in as many as 40% of patients prior to rupture. Polycystic kidney disease and coarctation of the aorta are also associated with cerebral aneurysm.

On the Rovibrational Levels of the H3 ÷ and H2d ÷ Molecules
Variationally exact rovibrational levels for the H3 + and H2D ÷ molecules are calculated using a recently published accurate potential. Vibrational fundamentals are va1=3191 cm-1 and vE=2494 (2521.6) cm-1 for H3 + and vl=3000cm-1, v~=2184cm-x and v3=2310cm-1 for H~D +. For H3 + calculated ground state rotational constants are B0 = 43.51 (43-57) cm-1, Co = 20.59 (20-71) cm-1, Dj ° = 0.04 (0.05) ...

We show that Skyrmions with massless pions in hyperbolic space provide a good approximation to Skyrmions with massive pions in Euclidean space, for a particular relationship between the pion mass and the curvature of hyperbolic space. Using this result we describe how a Skyrmion with massive pions in Euclidean space can be approximated by the holonomy along circles of a Yang-Mills instanton. Th...

This article outlines the participation of the Documents and Linguistic Technology (DLT) Group in the Cross Language French-English Question Answering Task of the Cross Language Evaluation Forum (CLEF). Following our experiences last year (Sutcliffe, Gabbay and O'Gorman, 2003), our aim was to improve the system particularly in the early stages of processing, and to make further refinements to o...
