Surgically speaking, history is likely to dub the 1990s as 'the laparoscopic years', as changes in surgical practice cause one of the biggest revolutions in our hospitals since the arrival of general anaesthesia. As a result, surgeons are having to re-examine their skills and training, while managers need to update their infrastructure for budgets and ...

Metallurgical and Materials Transactions B, 1995
The size and temperatures of the keyhole have been calculated through the thickness of the plate being welded. The temperature calculations are based on a critical intensity and the power loss resulting from vaporization. The evaporative power loss is set equal to the Gaussian power density, which is used to represent the laser beam.
