This thesis describes evaluation of a novel self-sealing chewable sustained release tablet that can maintain controlled release of drug regardless of compaction, crushing, or chewing. The new formulation contains polyethylene oxide which produces a sealant effect for cracks produced in the polymer coating during compaction. Dissolution studies were conducted and...
The numerical modeling of motions in the atmosphere's
planetary boundary layer (PBL) is a challenging task. In
general, the boundary layer interacts with both the overlying
atmosphere and the underlying land or water surface
in a complex manner. Random turbulence is also present in
the PBL which precludes exact prediction...
A satellite-derived Climatology of Global Ocean Winds (COGOW) on a 0.5° latitude by 0.5° latitude grid is presented based on 5-years (August 1999 July 2004) of measurements from the SeaWinds scatterometer that was launched on 19 June 1999 onboard the QuikSCAT satellite. SeaWinds is an active microwave radar that estimates...
The effect of concentration, vehicle and surfactant on the
absorption of benzocaine -³H across the rat's rectal mucosa was
investigated. Blood radioactivity levels were determined after the
application of benzociane -³H containing suppositories and ointments.
A wet oxidation method was used for sample digestion. Since the
radioactivity counted is the...
Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...
The forest products industry often uses intermediate-support cable logging systems to transport logs from the harvest site to a staging area. A method is presented to assist in the analysis and design of these cable systems. The method determines tensions in individual cables, forces on and stresses in the support...
Propionic acid, live Propionibacterium shermanii, and
Dimethyl Fumarate (DMF) were tested for their stimulatory or
inhibitory efects on yeast, bacteria, and molds. The amount
of propionic acid required for inhibition of molds was
strain specific and equal to or less than that required for
inhibition of the yeasts. Live P....
Improved assay methods for determination of dyphylline levels in plasma, saliva, and urine utilizing high pressure liquid chromatography have been developed. Detection of levels as low as 25 ng/ml from 0.5 ml plasma and 50 ng/ml from 0.5 ml saliva were possible. Both procedures utilized the same extraction process. A...
