Focal intestinal metaplasia is the potentially reversible change from a fully differentiated stomach cell type to an intestinal cell type. It is associated with significantly increased risk of cancer. . Proper diagnosis and treatment can reduce the risk of gastric cancer. slide 1 of 6.
The ozone depletion potential (ODP) of a compound is a simple measure of. its ability to destroy stratospheric ozone. It is a relative measure: the ODP of CFC-11 is defined to be 1.0, and the ODP's of other compounds. are calculated with respect to this reference point. Thus a compound with.
Causes. The main cause of Ozone Depletion are CFCs. CFC's drift in the environment until they reach the stratosphere. The UV radiation splits the chlorine from CFC's which attracts one of the three ozone atoms and destroys the ozone into ordinary oxygen.CFC's were ordinarilly used to replace the ammonia and its effects.he UV radiation splits the chlorine from CFC's which attracts one of the three ozone atoms and destroys the ozone into ordinary oxygen.
