The potential of magnesium alloys as bioabsorbable / biodegradable implants for biomedical applications has been extensively studied as emerging direction. This paper gives a review of current topics in this field. Research activities related to biomedical magnesium alloys have been pursued in two main directions, orthopedic and cardiovascular implants, by investigating different aspects of all...

National Thermal Power Corporation (NTPC) has signed an MoU with Bhabha Atomic Research Centre (BARC) for design and development of automated boiler tube inspection system for vertical water wall tubes. A vertical climbing robot has been developed for this purpose at Division of Remote Handling & Robotics (DRHR), BARC. Recently, an Electromagnetic Acoustic Transducer (EMAT) has been integrated ...

We report the first case of a fracture of the standard C-stem in combination with a large metal-on-metal articulation. This occurred at the head-neck junction. Analysis of the fractured stem showed evidence of fatigue failure with possible corrosion. The use of large femoral heads with neck adaptors and narrow tapers should be used with caution, especially in heavy, active patients.

In June of this year, the FAA sponsored a meeting of representatives of the aviation industry to review problems associated with aging aircraft. While much of this meeting addressed issues of hardware, metal fatigue, and corrosion, there was a discussion of human factors in maintenance. Today's meeting reflects a growing interest in human factors and its potential contribution to continuing avi...

From the earliest attempts to successfully design and place dental implants, immediate loading and function have been hallmarks of treatment. Abundant failures in the early developmental stages of implants were commonplace and often occurred immediately or after a short period of functional loading. In many cases, patients were left with clinical problems more severe than their original edentul...
