To do a warm compress all you need to do is: 1  Take a clean and soft cloth and dip it in hot water. 2  Ensure the water is not too hot but a little more than warm. 3  Rinse the cloth. 4  Hold this warm cloth gently over your childâs sty for about five to ten minutes, depending on how comfortable your child is. 5  Do this a few times a day.
Rule #2: When abbreviating academic degrees and professional designations, use a period between each letter or element in the abbreviation. No internal spaces are necessary.
Over the years, however, the lack of convention in some style guides has made it difficult to determine which two-word abbreviations should be abbreviated with periods and which should not. The U.S. media tend to use periods in two-word abbreviations like United States (U.S.), but not personal computer (PC) or television (TV).
