Continuous extradural analgesia by means of repeated doses of local analgesic drugs through a catheter placed in the extradural space is now widely used in this country, both for the production of surgical analgesia and for the relief of pain. Using the caudal route, labour can be conducted painlessly, and by simply increasing the dosage the analgesia can be extended to cover a Caesarean sectio...

Definitions may be made up of one or more components, which correspond to strategic predicates. The selection of which components to use in giving a definition in a task-oriented dialogue depends heavily on the needs of the user. The selection strategy we present involves weighting possible strategic predicates and the propositiomL used to fill them at multiple points throughout an ongoing dial...

Recent development of Google Map, Yahoo! Map and MapQuest APIs have pushed map mashups almost to the top among other types of mashups such as news mashups, search and shopping mashups, and video and photo mashups. However, map mashups should not reply on these open data sources and services only. Developing a mashup in general faces a number of challenges. These include: 1) the difficulties in ...

New health technologies require development and evaluation ahead of being incorporated into the patient care pathway. In light of the recent publication by Lehoux et al who discuss the role of entrepreneurs, investors and regulators in providing value to new health technologies, we summarise the processes involved in making new health technologies available for use in the United Kingdom.

in our country, school bus routes are determined by experiments of driver without considering the scientific optimum route and location. traversing additional routes will always result an increase in vehicle movements and fuel consumption and enormous costs. hence, this paper will study the school bus routing in tehran considering special students and a model will be presented to minimize trave...

We present results from ChandraX-ray and Spitzer mid-infrared observations of the interacting galaxy pair NGC 6872/IC 4970 in the Pavo galaxy group and show that the smaller companion galaxy IC 4970 hosts a highly obscured active galactic nucleus (AGN). The 0.5Y10 keVX-ray luminosity of the nucleus is variable, increasing by a factor 2.9 to a luminosity of 1:7 ; 10 erg s 1 (bright state) on 100...

We demonstrate that generically an accretion disk around a compact object could have a new type of instability in that the accretion flow need not be symmetric with respect to the equatorial plane even when matter is supplied symmetrically farther out. We find that this behaviour is mainly due to interaction of outgoing matter bounced off the centrifugal barrier and the incoming accretion. We b...

This paper explores the practical application of life cycle assessment (LCA) to product system development. While life cycle assessment methods have been studied and demonstrated extensively over the last two decades, their application to product design and development has not been critically addressed. Many organizational and operational factors limit the integration of the three LCA component...
