Estrogen Curbs Appetite In Same Way As The Hormone Leptin. FULL STORY. Estrogen regulates the brain's energy metabolism in the same way as the hormone leptin, leading the way to a viable approach to tackling obesity in people resistant to leptin, researchers at Yale School of Medicine report in the December 31 online issue of Nature Medicine.
1. smokeless powder-an explosive (trade name Ballistite) that burns with relatively little smoke; contains pyrocellulose and is used as a propellant. Ballistite. explosive-a chemical substance that undergoes a rapid chemical change (with the production of gas) on being heated or struck.
Burnt black powder leaves a thick, heavy fouling that is hygroscopic and causes rusting of the barrel. The fouling left by smokeless powder exhibits none of these properties (though some primer compounds can leave hygroscopic salts that have a similar effect; non-corrosive primer compounds were introduced in the 1920s).his article focuses on nitrocellulose formulations, but the term smokeless powder was also used to describe various picrate mixtures with nitrate, chlorate, or dichromate oxidizers during the late 19th century, before the advantages of nitrocellulose became evident.
