Osteonecrosis of the femoral head is an uncommon complication following hip arthroscopy, generally due to an excessive traction of the limb and high intracapsular pressures of the hip. This complication entails catastrophic outcomes for the femoral head with collapse and degeneration, resulting in another surgical procedure. We present a case of a 21 year-old soccer player that underwent arthro...

background: fire and explosion hazards are extremely important in processing units. this study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. materials and methods: the present qualitative case study was conducted using dow’s index in 2015. the fire and explosion hazard index and leve...

Artificial Neural Network (ANN) is a valuable and well-established inversion technique for the estimation of geophysical parameters from satellite images. After training, ANNs are able to generate very fast products for several types of applications. Satellite remote sensing is an efficient way to detect and map strong earthquake damage for contributing to post-disaster activities during emerge...

The DNA damage response kinase ataxia telangiectasia and Rad3-related (ATR) coordinates much of the cellular response to replication stress. The exact mechanisms by which ATR regulates DNA synthesis in conditions of replication stress are largely unknown, but this activity is critical for the viability and proliferation of cancer cells, making ATR a potential therapeutic target. Here we use sel...

This work applies 64,765 simulated seismic ground motions to four models each of 6or 20-story, steel special moment-resisting frame buildings. We consider two vector intensity measures and categorize the building response as “collapsed,” “unrepairable,” or “repairable.” We then propose regression models to predict the building responses from the intensity measures. The best models for “collapse...

Progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. Both General Services Administration (GSA) and United States Department of D...

When arteries are excised, they collapse and shorten spontaneously, which can result in damage to the endothelium. To determine if an intact endothelial cell layer could be preserved in excised vessels, we isolated and cannulated rat carotid artery segments (in situ length, Lis, 10-20 mm) at both ends while maintaining both transmural pressure (70 mm Hg) and Lis, while either transmural pressur...

Real-time building damage detection effectively improves the timeliness of post-earthquake assessments. In recent years, terrestrial images from smartphones or cameras have become a rich source disaster information that may be useful in assessing at lower cost. this study, we present an efficient method based on combination with improved YOLOv5. We compiled Ground-level Detection Building Damag...
