The thermodynamic minimum energy for desalination (the energy required for separating an infinitely small amount of fresh water from salt water) is the same for all processes. Energy differences between processes are due to the difference in efficiency of the process.
June 25, 2003 -- Daily prednisone for 10 days reduces the relapse rate for patients with chronic obstructive pulmonary disease (COPD) treated and discharged from the emergency room, according to the results of a randomized controlled trial published in the June 26 issue of the New England Journal of Medicine.
Prednisone is prescribed to treat many different types of inflammatory conditions, everything from skin rashes to inflammatory bowel disease (IBD). 1  Prednisone may be given for only a short time, such as over a few days to much longer periods. Some people who take prednisone for chronic conditions have trouble stopping the drug because the symptoms return every time the dose is lowered. This is called steroid-dependent, and most physicians agree it's not an optimal form of treatment.
