normal 0 false false false en-us x-none ar-sa background: we aimed to compare peak systolic velocity of central retinal artery (psv.cra) and peak systolic velocity of ophthalmic artery (psv.oa) between patients with retinal detachment who were treated with segmental scleral bucking and scleral buckling with encircling procedure. materials and methods: this study was a descriptive-analytic cross...

conclusions according to our results, by omitting probable risk factors of incidence of sore throat and evaluation of role of hormonal changes in women represented in menstrual cycles, there was no significant association between menstrual cycle and sore throat incidence. results of 100 patients, in the first six hours, 51 patients had sore throat and 49 had no pain. during the first 6 hours, 3...

BACKGROUND Whereas taxation on alcohol is becoming an increasingly common practice in many countries as part of overall public health measures, the Hong Kong Special Administrative Region Government is bucking the trend and lowered its duties on wine and beer by 50 percent in 2007. In 2008, Hong Kong removed all duties on alcohol except for spirits. The aim of this paper is to examine the case ...

B ronchofiberoscopy for examination of the tracheobronchial tree has considerable advantages over conventional rigid bronchoscopy, not the least of which is ease of insertion into a lightly sedated patient. Introduction of the bronchofiber-scope via a sterile nasopharyngeal airway facilitates its passage, prevents its contamination by nasal secretions and protects the nasal mucosa from trauma (...

The Blake Fire burned about 730 ha of mature timber on the west slope of South Fork Mountain in northwestern California. Many steep innergorge and landslide headwall areas burned very hot, killing most large trees and consuming much of the large organic debris in unstable drainages. This created a potential for adverse effects on downstream fisheries from landsliding and the release of sediment...

The objective of this work was to study maritime pine (Pinus pinaster Ait.) wood characteristics and their impact on the sawing yield using virtual stem models and sawing simulation procedures. In the first part of the work, a characterisation of maritime pine as raw material for the wood industry was performed. The stem shape, distribution of knots, and heartwood/sapwood contents were studied....

BOOK REVIEW I do anatomize and cut up these poor beasts, he said to Hippocrates, to see the cause of these distempers, vanities, and follies, which are the burden of all creatures.-Democritus (1) Dualism, a belief in a fundamental opposition in all things like the body and the mind, good and evil, right and wrong, is found throughout ancient civilization. Dualism was expanded by John Cottingham...

Drs Cadamy and Booth condemn the use of rocuronium at rapid sequence induction (RSI) and advocate a propo-fol/alfentanil regimen as an alternative to thiopentone/suxamethonium (Anaesthesia 1999; 54: 817). Although a number of studies involving healthy subjects have shown that tracheal intubation can indeed be performed without neuromuscular block, there is no evidence that such propofol/opioid ...

Enormous quantities of geoelectrical dataare produced daily and often used for large scale res-ervoir modelling. To interpret these data requiresreliable and efficient inversion methods which ade-quately incorporate prior information and use realisti-cally complex modelling structures. We use modelsbased on random coloured polygonal graphs as a pow-erful and flexible...
