In many cases, crashes at intersections account for over 50% of all urban road accidents. The need to reduce these crashes has fostered considerable research on the development and evaluation of traffic safety at intersections. This paper introduces a micro-level behavioral method for estimating crash potential at signalized and unsignalized intersections for different traffic characteristics. ...

Safety cases are now regularly used to communicate the argument about the achievement of acceptable levels of safety for safety critical systems. Increasingly, safety standards such as Defence Standard 00-56 require the scope of the safety case to cover not only the development of the system, but also operating and maintenance through life, including decommissioning. This involves two dimension...

BACKGROUND Safety of cosmetic procedures in pregnant women has not been extensively studied. Maternal and fetal health risks are important to consider in any procedure performed. With the increasing popularity of cosmetic procedures, dermatologic surgeons will be faced with scenarios necessitating knowledge regarding the safety of such procedures during pregnancy.
