Accident statistics show a relatively low level of traffic safety in Jordan compared to developed countries producing large socio-economic losses. The number of accidents has increased five old-fold between 1995 and 2009 reaching 122,793 in 2009 with an estimated cost of JOD 336 million ( equivalent to about $504 million). This study investigates the present and future magnitude of road traffic...

Ischemic tracheal complications due to the ETT cuff occur in approximately 10 percent of mechanically ventilated critically ill patients despite the use of high-volume, low-pressure ETT cuffs. Using a laboratory model, we studied the effects of airway pressure on three different ETT cuff designs, including two "low pressure" designs. Positive airway pressure acted on the "low pressure" cuffs to...

Real-time operator workload assessment and state classification may be useful for decisions about when and how to dynamically apply automation to information processing functions in aviation systems. This research examined multiple cognitive workload measures, including secondary task performance and physiological (cardiac) measures, as inputs to a neural network for operator functional state c...

Pavement rehabilitation could affect the accident severity index (ASI) since restoration measures means more safety for road users. No research or project has been carried out to identify hazard points to build a linear model based on crash severity index. One of the very popular accident severity index models used in all countries is based on linear models to rehabilitate pavements and this pa...

We investigate the relationship between low-level political violence and communication patterns. Using network traffic from all Orange Côte d’Ivoire cell towers and 400 million calls from 500,000 randomly sampled cell phone subscribers, we show that in the days preceding small violent incidents, call volumes increase, driven by more active subscribers. Average call length decreases and calls be...

background: unlike industrially production, iranian traditional doogh are not pasteurized after production. hence, possible contamination with different pathogenic bacteria may occur during production or post-production of traditional doogh. the aim of the present study was to monitor the behavior of escherichia coli o157:h7 and listeria monocytogenes in traditional iranian doogh at different t...
