conclusions continuous portal triade clamping (the pringle maneuver) during liver ischemia (30 and 45 minutes) in rabbits resulted in no ischemic change. increasing time of clamping to 30 minutes was safe in intermittent pringle maneuver. materials and methods in an experimental study, 20 new-zealand white rabbits were selected. in laparotomy, a blunt dissector was passed through the foramen of...

Nine-hundred and seventy-three police road-accident files describing overtaking accidents were sampled from the headquarters of Nottinghamshire Constabulary, England, for the years 1989–1993. Salient facts were extracted from each case, including the exact manoeuvre involved, the principle explanatory factors, the driver(s) most at fault, and the drivers’ ages. Two kinds of reliability measure ...

Injury Prevention recently published a commentary critical of epidemiological approaches to cycling safety. The author, Kary, suggests that our paper, which reanalysed Walker’s study of motor vehicle overtaking distance for cyclists, made false claims about type I errors and confused statistical significance and clinical significance. Kary supports this critique, along with other points in the ...

Nowadays, the importance of the vehicles and its dramatic effects on human life is no secret. The use of trailers with multiple axels for transporting bulky and heavy equipment is essential. Increase in trailers axles which results increment of wheels, needs considerations in order to increase in transporting speed, maneuverability, safety, better control and path following accurately.  Therefo...

Two-way two-lane roads have a significant impact on road transportation infrastructure. Platoon formation is one of the factors that affect quality traffic flow roads. More specifically, creation platoon increases density vehicles and number overtaking maneuvers decreases performance The present study made an effort to investigate effect characteristics Moreover, it strived develop nonlinear re...

VEST is a set of four stream cipher families targeted to semiconductor applications. All VEST family members support efficient encryption, single pass authenticated encryption, and collision resistant hashing in the one low area module. VEST was submitted by Synaptic Laboratories Ltd. to the ECRYPT NoE eSTREAM project in 2005. Recently, a single digit typographical error was identified in the V...

Overtaking is one of the most dangerous operations in driving. The rear-view mirror is sometimes not consulted by the driver or is momentarily useless because of the blind spot. This paper describes a simple FPGA system based on motion detectors of the fly and rigid-body detection that is able to efficiently segment overtaking cars using a sparse map of features from the visual field of the rea...
