Development and application of a new passive sampling device : the lipid-free tube (LFT) sampler

Creator:: Quarles, Lucas W.
Abstract:: Contaminants can exist in a wide range of states in aqueous environments, especially in surface waters. They can be freely dissolved or associated with dissolved or particulate organic matter depending on their chemical and physical characteristics. The freely dissolved fraction represents the most bioavailable fraction to an organism. These freely...

A comparative study of the isozymic proteins and the effect of metachemogenesis in the tissues of Periplaneta americana (L.)

Creator:: Beckendorf, Gerald Walter
Abstract:: An attempt was made to demonstrate isozymic forms of esterase, MDH, LDH and GPDH and the variation in enzyme pattern with increasing age in the thoracic muscle, appendage muscle and hemolymph of the American cockroach, Periplaneta americana. Sampled specimens of both sexes were aged one through seven days, two weeks...

Investigation of Nematocyst Discharge in Parasitic Cnidarians (Myxozoa)

Creator:: Americus, Benjamin E.
Abstract:: Myxozoans are an enigmatic group of obligately parasitic, microscopic cnidarians. They diverged from their free-living relatives over 600 million years ago and have highly reduced genomes. However, they have retained nematocyst stinging cells which characterize the phylum Cnidaria. Free-living cnidarians utilize this cellular weaponry for defense and predation whereas the...

Analog integrated circuit design using GaAs C-HFETs

Creator:: Gupta, Rakhee
Abstract:: Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...

Estimates of heterosis in winter/winter, winter/spring, and spring/spring crosses of barley (Hordeum vulgare L.)

Creator:: Oakley, Stephen Roland
Abstract:: Previous work indicated a substantial heterotic expression for grain yield existed within winter/spring hybrids of barley, This research was a continuation for the comparison of the expression of heterosis within winter/spring hybrids to the heterotic effect produced among the winter and among the spring parents. The F₁ and F₂ progenies...

Disturbances in a marine bacterioplankton system drive community assembly towards niche-based processes

Creator:: Vergin, Kevin L.
Abstract:: Over 100 monthly bacterioplankton DNA samples, from each of the surface and 200 m depths at the Bermuda Atlantic Time-series Study (BATS) site, were analyzed for community assembly processes. Correlation networks, filtered for potential autocorrelation artifacts, were constructed for each depth. Network characteristics for the two depths were remarkably similar...

Measuring sediment transport rates using tracer gravel and RFID technology

Creator:: Lewis, Logan L.
Abstract:: Rates of sediment transport were determined using tracer gravel and a RFID antenna array at Oak Creek (Oregon) to compare a new method with an existing transport relation created from data previously collected in the same study reach. Close to 3,000 tracers were deployed throughout the study reach and were...

Monte Carlo uncertainty reliability and isotope production calculations for a fast reactor

Creator:: Miles, Todd L.
Abstract:: With the advent of more powerful, less expensive computing resources, more and more attention is being given to Monte Carlo techniques in design application. In many circles, stochastic solutions are considered the next best thing to experimental data. Statistical uncertainties in Monte Carlo calculations are typically determined by the first...

Growth rate of wheat (Triticum aestivm L., var. Gaines) as a function of moisture stress and nitrogen supply

Creator:: Amujo, Stephen Jimo
Abstract:: The effect of moisture stress and nutrients on the rate of growth of wheat (Triticum aestivum L. Var. Gaines) seedlings was studied. A special apparatus in which the moisture stress of several perlite cells could be maintained constant by osmotic solutions was used. Predetermined amounts of nitrogen were added to...
