Modern upwelling conditions and corresponding oceanographic properties are investigated and reconstructed for the Late Quaternary. The oceanographic conditions considered influence diatom ecology and the record of fossil diatom frustules in the sediments.
Diatoms from modern sediments are evaluated as paleoceanographic proxies and transfer functions (TFs) are calibrated using the Imbrie...
Sediments on the inner portion of the Oregon continental shelf
consist of clean, well-sorted, detrital sand. This sand has an average
median diameter of 2.53Φ (. 173 mm) and is both positively and
negatively skewed. Deposits with median diameters in the coarse
sand and gravel classes occur at depths of...
Since the late 1880's western juniper has expanded in range and
increased in density in sagebrush-bunchgrass, riparian, and forested plant
communities of the Pacific Northwest. Succession to western juniper
woodland has been shown to reduce the productivity and diversity of the
understory component, result in concentration of soil nutrients beneath...
The conflict over water resources exploitation and sharing in the Aral Sea Basin is one of the most pressing environmental issues yet to be resolved in Central Asia. The fall of the Soviet Union in 1991 and establishment of the New Independent States (NIS) within the Aral Sea Bain led...
The methodology to perform bioequivalence studies for prodrug products has not been finalized by FDA leaving the investigators to speculate over the proper approach. This study innovatively utilized the bootstrap methods for testing in vivo bioequivalence on both parent drug and metabolite of four prodrug products: Clopidogrel, Prednisone, Allopurinol, and...
The purpose of this study was to provide information
pertaining to performance levels of Dvorak keyboard operators
through retraining. More specifically, the purposes of
this study were:
1. To compare operator performance rates on the
Dvorak keyboard with operator performance
rates on the Qwerty keyboard.
2. To determine whether keyboard...
