A new system called sequential/parallel matrix grammars
for two-dimensional pattern processing is introduced and studied.
Miscellaneous language operations such as union, catenation (row
and column), Kleene's closure (row and column) and substitutions
are investigated. The equivalence of sequential/parallel matrix
languages and finite-turn repetitive checking automata is established.

Albumin, as a percent of total proteins in both the coelomic
serum and the blood serum, was determined for four groups of
developing Rana catesbeiana tadpoles by cellulose acetate electrophoresis.
Also, using Folin phenol reagent, the total protein of
each the blood serum of metamorphosing tadpoles and the coelomic
serum...
Chromosome maps were made of Drosophila gibberosa salivary gland
and fat body chromosomes, and the puffing patterns were compared in
the two tissues for selected times in development. The times were
early third instar (E), late third instar (0, at pupariation
(0 hr), at two hours (2 hr), four hours...
