Grammar's Response. The choice of open/opened depends on what we're talking about. Yes, we can say (and often do) that the store is open, but if we're talking about the actual process of someone opening the doors, we'd say The store is opened every morning at 8 o'clock..
Ethanolamine (C2H7NO) is used in the pharmaceutical industry as a pH adjuster and buffering agent. It is a colorless to yellow clear liquid. There is evidence that it can be a human skin toxicant or allergen, and it should not be left on the skin. It has certain restrictions for use in the cosmetics industry. Ethanolamine oleate, a prescription drug, is a sclerosing agent. It works by creating scar tissue inside a swollen or dilated (wider than normal) vein to prevent bleeding.
Ethanol is a 2-carbon alcohol, responsible for the behavior-altering effects of Alcoholic Beverages, and for the devastation of the social and physical well being of alcoholics and their communities. This alcohol is a simple molecule, a carbohydrate, which is burned as a fuel supplying energy to cells. Ethanol in its disguise as a fuel can be considered a non-essential nutrient. But before it is metabolized as a fuel, it is an active brain-drug and an all-purpose cellular toxin. As a brain drug, ethanol acts to depress brain function from the top down, very much in the style of an anaesthetic. With low blood concentration, the cortical depression of ethanol seems to release behaviors that are otherwise inhibited. At this low level of mind intoxication, ethanol is useful and possibly pleasant.
