The highest levels of arsenic (in all forms) in foods can be found in seafood, rice, rice cereal (and other rice products), mushrooms, and poultry, although many other foods can contain low levels of arsenic. Rice is of particular concern because it is a major part of the diet in many parts of the world.
Ergine, also known as d-lysergic acid amide (LSA) and d-lysergamide, is an alkaloid of the ergoline family that occurs in various species of vines of the Convolvulaceae and some species of fungi.
LSA is the Lobe Separation Angle or the number of degrees between the intake and exhaust lobe centerlines. The LSA has a direct relationship to amount of overlap on a cam. Cams with identical duration and lift specifications can have very different LSAs. Generally speaking, a wide LSA will produce greater low end torque and a narrow separation angle will produce better top end power.
