At the submerged margins of the North Atlantic, andesitic to dacitic and basaltic volcanic rocks occur together. The silicic rocks were derived by processes requiring the presence of continental crust (crustal anatexis and/or contamination of mafic magmas) while the majority of the basaltic lavas had little or no contact with...
Death of flower parts near bloom due to inflorescence necrosis (IN) is associated with high ammonium (NH₄⁺) concentration in flower clusters, shade, cool wet weather preceding bloom, and excessive vigor. Faults in NH₄⁺ assimilation are suspected to cause a rise in NH₄⁺ concentration to toxic levels in flower cluster but...
The closed insulated pallet system (CIPS) was evaluated for growth, yield, and
fruit quality of tomato genotypes with determinate growth habit. Plants were irrigated
with several levels of sodium chloride (NaCl) salinized water. Tomato growth and yield
were significantly greater in CIPS than in conventional surface-irrigated containers,
regardless of irrigation...
A numerical model is developed to estimate wave forces on A-Jacks armor units. The forces include drag, inertia, buoyancy, and slamming as the unit penetrates the free surface. The wave force model is used to determine the rigid body motions of the units. Bulk forces on a matrix of units...
Determination of the source and fate of natural (higher plant lipids, marine
lipids, etc.) and anthropogenically (e.g., petroleum, coal emissions) derived
hydrocarbons and oxygenated compounds in the environment was accomplished
using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS)
to characterize or identify molecular biomarkers to be utilized as tracers....

A novel type of model substrates, i.e. immobilized p-aminophenyl-β-D-cellooligosaccharides,
was developed and used in the study of exocellulases. The
two major cellobiohydrolases from Trichoderma reesei, CBH I and CBH II were
used as representative enzymes. p-Aminophenyl derivatives of cellobiose (PAPG₂),
cellotriose (PAPG₃), and cellotetraose (PAPG₄) were synthesized from the reaction...
