The influence of the pavement friction coefficient evolution caused by traffic flow on the risk of motorway horizontal curves

The friction coefficient between the tire and the road is one of the key parameters affecting road traffic safety.The purpose of this paper is to quantify the risk of skidding for the vehicles due to the friction evolution caused by the traffic polishing in the horizontal curve.Based on the reliability theory, an innovative dynamic risk assessment

Reduction and fixation of comminuted fractures of the midface by using a Hoffman-type external fixator: A case report

Internal fixation using plates remains the gold standard Wooden Dollhouse for facial fracture fixation.External wound fixators are rarely used.In the present study, we successfully treated multiple comminuted facial fractures with midfacial depressions by using a Hoffman-type external fixator and achieved good functional and cosmetic results.Intern
