BACKGROUND Concerns about duty hour and resident safety have fostered discussion about postshift fatigue and driving impairment. OBJECTIVE We assessed how converting to a night float schedule for overnight coverage affected driving safety for trainees. METHODS Brake reaction times were measured for internal medicine and orthopaedic surgery resident volunteers after a traditional 28-hour cal...

Background: Iran is a country with a high rate of natural disasters like earthquake. The environmental conditions slow down the delivery of health services, especially in the event of disasters. The modern technologies such as telemedicine are appropriate for facilitating disaster relief operations after an earthquake. This study aimed to develop a model for the implementation of telemedicine i...

The Longmen Shan is the steepest topographic front at the India-Asia collision zone and the site of the Mw 7.9 Wenchuan earthquake. Here to explain the interseismic GPS velocities across the greater Longmen Shan region, we develop a boundary element model including earthquake cycle effects, topography, the westward dipping Beichuan Fault and a ∼20 km deep, shallowly dipping, detachment, inferre...

In this study we determined neural network weights and biases by Imperialist Competitive Algorithm (ICA) in order to train network for predicting earthquake intensity in Richter. For this reason, we used dependent parameters like earthquake occurrence time, epicenter’s latitude and longitude in degree, focal depth in kilometer, and the seismological center distance from epicenter and earthquake...

Aim of the study was the assessment of coping strategies, specifically substance use and post-traumatic growth (PTG), in 411 college students two years after 2009 L'Aquila earthquake. Post-Traumatic Growth Inventory (PTGI) was used to assess PTG and one question about substance use (alcohol, tobacco, cannabis) was asked to verify if students had modified their use in the post-earthquake compare...

The moment magnitude (Mw) 7.9 Fort Tejon earthquake of 1857, with a approximately 350-kilometer-long surface rupture, was the most recent major earthquake along the south-central San Andreas Fault, California. Based on previous measurements of its surface slip distribution, rupture along the approximately 60-kilometer-long Carrizo segment was thought to control the recurrence of 1857-like earth...

On March 11, 2011, Japan was consecutively hit by three unprecedented disasters caused by The Great East Japan (Tohoku) Earthquake: an earthquake of magnitude 9.0, an incredibly powerful tsunami, and a nuclear power plant breakdown. As Japan had experienced The Great HanshinAwaji Earthquake in 1995, we were prepared to provide the victims with appropriate medical care to some extent. Neverthele...

An extremely large earthquake (with magnitude of 8.2) happened on 8 August 1993 near the Guam island, and ultra-low-frequency (ULF) (frequency less than 1 Hz) electromagnetic fields were measured by 3-axis induction magnetometers at an observing station (with the epicentral distance of 65 km) with sampling frequency of 1 Hz. In order to study electromagnetic signature of prefracture criticality...
