This study investigated the relationships between selected
perceptual-motor behaviors and the following: achievement in reading,
achievement in mathematics, academic self-concept, academic
motivation and classroom behavior. This investigation was designed
to explore the suggestion of Newell Kephart that there is a relationship
between perceptual-motor behavior and school success, and to
provide...
Management factors used for studies on potato scab
control were evaluated for their effect on tuber russeting
and related biochemical and anatomical parameters
during 1971 and 1972.
Russet Burbank potatoes were irrigated in 1971 to
maintain high available soil moisture (between 90% and
field capacity) for 0, 3, 6 and...
Pre-harvest foliar desiccation of Yellow Globe Danvers onions was
investigated as a means to improve harvest procedure and to reduce
storage losses. Foliar desiccation tended to increase storage disease
and sprouting incidence versus the untreated controls. Paraquat
approximately doubled storage disease in both years. Stoddard solvent
and ethephon increased disease...
The tosylhydrazones of exo-3-deuteriocamphor and 2- deuterio-2,4-dimethy1-3-pentanone were treated with Nbromosuccinimide (NBS) and pyruvic acid to regenerate the parent ketones. The ketones from the pyruvic acid cleavage show a significant loss of deuterium. The ketones from the NBS cleavage show no loss of deuterium, indicating that stereochemical integrity at. C[subscript...
Bacillus subtilis α-amylase was used to hydrolyze
starch from peeled and whole potatoes (Solanum tuberosum).
Effect of gelatinization temperature, pH, enzyme concentration,
temperature of hydrolysis and presence of calcium
ions were investigated. Optimum conditions for hydrolysis
were when α-amylase levels were 0.3 percent of the starch
concentration in the presence...
