The phthalic anhydride (3 eq) is added portion-wise as a solid to maintain the temperature in the reactor below 45° C. After completion of phthalic anhydride addition, the mixture is heated to 45° C. After stirring for an additional 4 hours, the heat is turned off 10% w/w aqueous ...
encompass over half of extant vertebrate species and possess an evolutionary history of at least 415 myr [2,3]. This extant diversity is unevenly distributed among three major clades: Cladistia (bichirs and the reedfish), Chondrostei (sturgeons and paddlefishes), and Neopterygii, the latter ...
Arcuate deltas are the commonest form of delta. They are fan-shaped, with the wide portion of the fan farthest from the mainland. Crossed by many short, well-defined distributaries, these types of deltas are composed of relatively coarse sediments. Wave and river activity are fairly well ...

This is the first demonstration that O proteins with internal deletions can complement for O activity, and that expression of the N-terminal portion of gene P can completely prevent O complementation. We show that O-P co-expression can limit the lethal effect of P on cell growth. We explore...
