Top. A horizontal asymptote is a y-value which a function approaches. The asymptote is parallel to x axis, so is of the form y = a, for all real values of a. Thus if f(x) = y is a function, then y = a, becomes undefined for the function, then the line y = a, is called the asymptote for the function y = f(x).
The African armyworm (Spodoptera exempta) also called okalombo, kommandowurm, or nutgrass armyworm, is an African moth. It is a very deleterious pest, capable of destroying entire crops in a matter of weeks.
Army manuals also included a number of so-called enemy manuals. They are manuals -- which are official US Army publications -- concerning enemy equipment or forces. The letter E in the manual number indicates that a particular manual is an enemy manual. For example, Technical Manual TM E9-803 on the German Volkswagen appears just after Technical Manual TM 9-803 on the Jeep.. A number of enemy manuals about foreign forces are included, like TM E30-420, Handbook of the Italian Military Forces.
