Presuppositions are very important in our understanding of how background and context determine the interpretation of a sentence. However, if we study some of the things that have been claimed to be presuppositions, we find that it is a very miscellaneous collection of things. Here are some examples: (1) Harry saw the man kiss her presupposes that Harry and the man denote uniquely existing, for...

introduction: gutta-percha (gp), is a neutral and non-toxic material. the aim of this animal study was to compare the biocompatibility of nanosilver coated gp (ns-gp) with conventional gp in subcutaneous tissues in a rat model. methods and materials: conventional gp and ns-gp were subcutaneously implanted in the backs of 20 male wistar rats ( n =10). a control animal was assigned for each trial...

We introduce a fractional version of the illumination problem of Gohberg, Markus, Boltyanski and Hadwiger, according to which every convex body in R is illuminated by at most 2 directions. We say that a weighted set of points on Sd−1 illuminates a convex body K if for each boundary point of K, the total weight of those directions that illuminate K at that point is at least one. We define the fr...

Given r > 1, we search for the convex body of minimal volume in E3 that contains a unit ball, and whose extreme points are of distance at least r from the centre of the unit ball. It is known that the extremal body is the regular octahedron and icosahedron for suitable values of r. In this paper we prove that if r is close to one then the typical faces of the extremal body are asymptotically re...

AIM  The aim of this study was to systematically review the literature on the influence of enhanced recovery after surgery (ERAS) protocols and health related quality of life (HQoL) and patient satisfaction. METHOD A systematic review of the literature from January 1990 to February 2009 was undertaken. Studies were included if they compared HQoL and/or patient satisfaction after ERAS and conv...

Knowledge about low flow statistics is essential for effective water resource planning and management in ungauged orpoorly gauged catchment areas, especially in arid and semi-arid regions such as Iran. We employed a data set of 20 riverflow time-series from the Iranian Central Plateau River Basin, Iran to evaluate the low-flow series using several frequencyanalysis methods and compared the resu...

OBJECTIVE Successful endodontic therapy depends on adequate mechanical and chemical debridement of the canal which requires knowledge of the canal morphology. Conventional radiography has been used to evaluate the canal type; however, direct digital radiography has recently been practiced for this purpose due to the shortcomings of conventional radiography. The aim of the present study was to c...

BACKGROUND AND PURPOSE Robotic-assisted walking training after stroke aims to enhance the odd of regaining independent gait. Recent studies have suggested that this approach is more effective than conventional therapy alone only in severely affected patients. We determined whether these results persist at long-term follow-up. METHODS Forty-eight nonambulant participants after subacute stroke ...
