Last year, China distributed a draft policy to foreign executives that called for barring the export of some of the rare earth elements that are in the shortest supply, and happen to be mined mainly in southeastern China using some of the most environmentally damaging techniques.
So is working with the fishermen it licenses to control overfishing by expanding closed areas and converting trawlers — boats that drag weighted nets across the ocean floor — to engage in more gentle and less ecologically damaging techniques like using traps, hooks and line, and seine netting.
By sparing the surface epithelium, less crusting and synechiae formation occur postoperatively than with cautery or surface-damaging techniques.
A wrong technique can damage your knees.
Experimental observation showed that the effectiveness of finding of damaged zone is dependent on the damage observation techniques.
The development of various damage detection techniques is discussed from a historical perspective, and the ability of these techniques to detect damage in helicopter transmissions is reviewed.
Once such levels are present, damage identification techniques can be applied effectively to locate damage.
Then three damage quantification techniques are studied to identify damages more precisely.
Vibration-based damage detection techniques have been used to detect damage in bridge beams.
Comprehensive reviews of damage modeling techniques can be found in Williams and Sexsmith (1995) and Heo (2009).
