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.
The breaking up action releases Chlorine atoms. Chlorine atoms react with Ozone, starting a chemical cycle that destroys the good ozone in that area. One chlorine atom can break apart more than 100,000 ozone molecules. Ozone layer depletion is best illustrated or explained with the Ozone Bucket Analogy.
