Answer to Question 1

The thin copper coating is easily damaged by overheating if the oxyacetylene torch flame is an oxidizing flame or if too much time is taken during brazing.

Answer to Question 2

All the system capacity does not go into changing the air temperature; some capacity is used to condense water on the evaporator coil. The system capacity and the amount of latent cooling versus sensible cooling varies depending upon the system operating conditions, making temperature drop calculations inaccurate.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
