Mitchell Marsh, a tidal salt marsh in the Salmon River Estuary, was diked in the
early 1960s. Restoration of the marsh, which began in late 1978, consisted of partial dike
removal. Several studies have been conducted in the marsh, addressing the status of the
developing salt marsh plant communities. Species...
Surface disinfection of fertilized fish eggs is widely used in aquaculture to reduce
extraovum pathogens that may be released from brood fish during spawning, and this is routinely
used in zebrafish (Danio rerio) research laboratories. Most laboratories use approximately 25-50 ppm unbuffered chlorine solution for 5-10 min. Treatment of embryos...
The subcellular fractions of liver and kidney from three bearded
seals (Erignathus barbatus nauticus) and three walrus (Odobenus
rosmarus divergens) were analyzed for cadmium and mercury content,
and the results were compared with the results of subcellular
fractionation of the same organs from two sea lions (Zalophus callfornianus
californianus) obtained...
The enzymes and pathways involved in the catabolism of
glucose by several strains of Streptococcus diacetilactis, Streptococcus
cremoris, and Streptococcus lactis, commonly called the
lactic streptococci, were studied. The presence of aldolase,
triosephosphate isomerase and alcohol dehydrogenase in these
organisms provided evidence for the operation of the Embden-Meyerhof-Parnas (EMP) pathway...
Anthocyanin degradation in freeze-dried strawberry puree was studied under various relative humidity conditions at 37°C. Moisture was found to be the determining factor in the rate of pigment degradation. Storage at relative humidities below 11% provided good pigment retention in this low-moisture product. Enzymatic degradation of the anthocyanin pigment did...
An effort was made to determine what factors are responsible for differences in color quality between preserves commercially manufactured from Hood and Tioga strawberry varieties. Color analyses made on Hood and Tioga preserves, during a 26 week storage period, included spectral measurements of aqueous extracts from the preserve samples. In...
Polybenzimidazoles were synthesized from 3,3'-diaminobenzidine (DAB) and dicarboxylic acids. The polymerizations using the dicarboxylic acid monomers were carried out in polyphosphoric acid (PPA) and phosphorus pentoxide/methansulfonic acid (PPMA) which acted as the solvent and condensing agent. The resulting polybenzimidazoles had inherent viscosities in the range of 0.12 to 0.84 dL/g....
