At present, great cities try to prevent from high levels of pollution and traffic jam by restricting the access of vehicles to centric zones. They are also known as Low-Emission Zones (LEZ). Some of the most important issues of LEZs are the risk of losing privacy of the citizen who drives through the LEZ and a significant error percentage on detection of fraudulent drivers. In this article, an ...

OBJECTIVE To identify risk factors for recurrence of tuberculosis. METHODS We studied a cohort of 610 patients with active pulmonary tuberculosis who were enrolled for treatment between 1989 and 1994 and cured using a three-drug treatment regimen of rifampin, isoniazid and pyrazinamide (RHZ).

The U.S. Department of Transportation (DOT) Office of Hazardous Materials Safety estimates that an average of over 800,000 shipments of hazardous materials (HAZMAT) are made each day in the United States [27]. The DOT also reports that approximately 1.5 billion tons of hazardous materials are shipped each year [26]. The majority of the hazardous material shipped is classified as flammable liqui...

Roadworks are essential to a safe and efficient road network, yet somewhat paradoxically the necessary work is often associated with increased risk to motorists and workers, as well as with traffic flow disruptions. A major source of increased crash risk at roadwork sites (work zones) is poor speed limit compliance. Speeding in work zones is examined in existing literature to the extent that ma...
