PURPOSE To define the variations of the courses of the cranial nerves and the inferior petrosal sinuses as they enter and traverse the jugular foramen. METHODS Thirty-nine cadaveric specimens containing the jugular foramen were scanned with 1-mm contiguous axial and coronal CT sections. Each specimen was dissected to evaluate the position of the cranial nerves and inferior petrosal sinus as t...

The finding that drivers may react to safety interventions in a way that is contrary to what was intended is the phenomenon of behavioural adaptation. This phenomenon has been demonstrated across various safety interventions and has serious implications for road safety programs the world over. The present research used a driving simulator to assess behavioural adaptation in drivers' speed and l...

In constructing a time histogram of the event sequences derived from a nonstationary point process, we wish to determine the bin width such that the mean squared error of the histogram from the underlying rate of occurrence is minimized. We find that the optimal bin widths obtained for a doubly stochastic Poisson process and a sinusoidally regulated Poisson process exhibit different scaling rel...

the aim of this project is to fabricated an aluminium-copper bimetal through the fusion method and examine its performance. an aluminium-copper-aluminium bimetal was built by the laser cladding method. the laser power as well as the annealing time effects on its interfacial properties of the bonding’s formed through the laser cladding were investigated. to fabricate the multilayer bimetal, the ...

conclusions noninvasive assessment of the patient hydration condition using the ultrasound is a simple and practicable measure in emergency. with regard to the considerations, it is possible to estimate cvp via diameter measurement and cross-section of the central veins. results twenty patients with the mean age of 60.3 were studied. the main reason for cardiac catheterization was shock. there ...
