INTRODUCTION Previous work suggests that patients with isolated penetrating trauma rarely require spinal immobilisation. This study aimed to identify the incidence of mechanically unstable, or potentially mechanically unstable, spinal column injuries in penetrating trauma patients. The study also aimed to identify the incidence of spinal cord injury as a result of penetrating trauma in Scotland...

In this paper we consider a family of active scalars with velocity field given by u = ? ? 1 + ? ? ? ? , for ? ( 0 ) . This equations is more singular version the two-dimensional Surface Quasi-Geostrophic (SQG) equation, which would correspond to We evolution sharp fronts studying families almost-sharp fronts. These are smooth solutions simple geometry in transition solution occurs tubular neigh...

To examine factors associated with blood exposure and percutaneous injury among health care workers, we assessed occupational risk factors, compliance with standard precautions, frequency of exposure, and reporting in a stratified random sample of 5123 physicians, nurses, and medical technologists working in Iowa community hospitals. Of these, 3223 (63%) participated. Mean rates of hand washing...

The Kolmogorov Zero-One law states that for tail events on infinite-dimensional probability spaces, the probability must be either zero or one. Behavior analogous in a natural sense to this exists on finite-dimensional spaces as well. Events exhibiting this behavior are said to have a sharp threshold. Let Qn = {0, 1}n be the discrete hypercube with the probability measure Pp defined by Pp(ω1, ω...

“Whiplash Injury” describes those injury deriving from the sharp whipping movement of both head andneck, produced at moment a traffic accident, particularly following collision behind, head-on orside collisions. The use safety belts has led to reduction in deaths front-end collisions, butalso an increase cases typical whiplash. There are two types forces that cause whiplash injuries inrear-end ...
