Tunnel safety can experience an innovative advance due to an increased awareness of dangerous goods vehicles and the monitoring of potentially dangerous overheated vehicles before the tunnel entrance. The overhead 3D vehicle classification system with laser scanners and conventional digital and infrared cameras enables the automatic generation of highly accurate and reliable data on risk bearin...

Drugs in short supply, especially those needed in oncology, can create legal and patient-safety problems for risk-bearing providers.

background: appropriate endurance exercise can change bone mass density and strength of weight-bearing bones in both animals and humans, but its effects on the microstructure are not known. this study aimed to determine skeletal changes induced by the treadmill running endurance in ovariectomized adult mice. methods: twenty-seven adult female rats were divided into experimental and control grou...

This case report describes the presentation of an obese patient with status Post Coronary Artery Bypass Surgery (CABG), severe bilateral knee osteoarthritis who was enrolled into traditional outpatient cardiac rehabilitation program including both weight bearing and non weight bearing aerobic exercise then she developed severe knee pain and effusion after 2 sessions, she stopped the exercise an...

BACKGROUND To address the long-term problems of bearing surface wear and osteolysis associated with conventional metal-polyethylene (M-PE) total hip arthroplasty (THA), metal-metal (M-M), and ceramic-ceramic (C-C) bearings have been introduced. These bearing surfaces are associated with unique risks and benefits and higher costs. However the relative risks of these three bearings in an older po...

We reviewed the literature on the currently available choices of bearing surface in total hip replacement (THR). We present a detailed description of the properties of articulating surfaces review the understanding of the advantages and disadvantages of existing bearing couples. Recent technological developments in the field of polyethylene and ceramics have altered the risk of fracture and the...
