Background & Aims: Traffic accidents are a major cause of disability and mortality around the world and a major public health problem in developing and developed countries. The aim of this study was to assess the burden of road traffic accidents in Isfahan, Iran. Methods: This cross-sectional study was conducted in Isfahan in 2010. Data were collected from death registration system to calculate...

Modern elevator systems in high-rise buildings consist of groups of elevators with centralized control. The group control allocates hall calls to the most suitable elevators by optimizing a cost function. This problem can be viewed as a combination of online scheduling, resource allocation, and stochastic control. The usual performance criterion to be optimized when scheduling passenger pick-up...

In the locust flight system, afferents of a wing hinge mechanoreceptor, the hindwing tegula, make monosynaptic excitatory connections with motoneurons of the elevator muscles. During flight motor activity, the excitatory postsynaptic potentials (EPSPs) produced by these connections changed in amplitude with the phase of the wingbeat cycle. The largest changes occurred around the phase where ele...

The latest elevator systems have structural differences from traditional systems, such as the use of destination calls, or multiple cars in the same hoistway. This requires the development of new elevator group control systems, which is best done by adopting modern soft-computing methods. We review some of these systems and the results of research so far, and suggest further directions of resea...

The purpose of this study was to extend previous examinations of commercial multi-crew airplane accidents and incidents to evaluate the Crew Resource Management (CRM) application as it relates to error management during the final approach and landing phase of flight. With data obtained from the Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB), a x test o...

This is a cross-sectional study of work-related accidents among traditional fishermen in the Medium Araguaia River region of Tocantins, Brazil. From June to August 2002, fishermen from the Municipality of Araguacema were interviewed about the organization of their work activities and work-related accidents during the previous six months. Of the 92 participating fishermen, 56 reported having suf...

Background and study aims: Endoscopic retrograde cholangiopancreatography-related infections are of increasing global concern due to the emergence of multidrug-resistant bacteria such as carbapenem-resistant enterobacteriaceae (CRE), with bacterial biofilm production postulated as one cause of persistent infection from such virulent organisms. Because N-acetylcysteine (NAC) has been shown to po...
