Drilling to investigate extreme environmental changes

Drilling resistance: A method to investigate bone quality.

PURPOSE Bone drilling is a major part of orthopaedic surgery performed during the internal fixation of fractured bones. At present, information related to drilling force, drilling torque, rate of drill-bit penetration and drill-bit rotational speed is not available to orthopaedic surgeons, clinicians and researchers as bone drilling is performed manually. METHODS This study demonstrates that ...

To Investigate Environmental effects of HVDC versus HVAC Transmission Systems

Alternating current (AC) has few drawbacks which have increased the demand of Direct current (DC) Transmission. The normal HVAC range is between 220-800 kV .This high voltage has to pass different types of terrains including settled area, mountains and water. It is quite clear that human beings and environment will be effected from this huge voltage. The common effects of these huge voltages ar...

Extreme sensitivity of graphene photoconductivity to environmental gases

Graphene is a single layer of covalently bonded carbon atoms, which was discovered only 8 years ago and yet has already attracted intense research and commercial interest. Initial research focused on its remarkable electronic properties, such as the observation of massless Dirac fermions and the half-integer quantum Hall effect. Now graphene is finding application in touch-screen displays, as c...
