The development of new electronic devices and design procedures
applicable to ternary switching circuits suggests that it might be desirable
to use ternary arithmetic in direct digital control systems.
The advantages of decimal, binary, and ternary arithmetic in digital
computers are discussed and a set of rules for signed -digit...
Numerous fishery researchers have attempted to preserve viable fish sperm, but only three investigations were successful in the fertilization of fresh eggs with frozen and thawed sperm: Blaxter (1953); Hoyle and Idler (1968); and Graybill and Horton (1969).

Achlys triphylla, a member of a medicinally active family
containing alkaloids, was examined phytochemically to determine its
possible value as a source of medicinal agents.
Pharmacological testing of the crude ethanol extract exhibited
a competitive inhibition of acetylcholine and histamine. Purification
of alkaloid 'A' from the crude ethanol extract and...
