Traditionally, M. chitwoodi is controlled with
chemical nematicides, many of which risk
suspension for use on potatoes due to health and
environmental concerns. It is essential to develop
and refine alternative strategies for controlling
Columbia root-knot nematode now, so that
productive and profitable potato acreage will not
be lost if...
Nitrogen (N) is an important nutrient for crop growth. Winter cover crops planted after a commercial crop is harvested, or relay planted before harvest, can provide N for subsequent crops, thus saving money and improving soil quality. Furthermore, cover crops can recover N remaining in the soil following summer crops,...

Cover crop selection and management depend on many factors, among them the cover crop’s ability to accumulate dry matter (i.e., residues) and nitrogen (N). Dry matter provides energy for soil organisms, contributes to soil organic matter, improves tilth, and acts as a sink for nutrients.
Studies of δ¹⁸O held in freshwater bivalve shell carbonate are useful for reconstructing paleoclimates and environmental changes and inform interpretations about past human behavior and periods of culture change. Stable isotope analyses (δ¹⁸O) of Margaritifera falcata shells found at the Cooper's Ferry archaeological site located in the lower Salmon River...
New product development has been considered a key success factor for today's businesses. Long term survival of many manufacturing organizations depends on how successful organizations are introducing new products to compete in existing markets or in creating new markets. Despite the importance of new product development, many manufacturing organizations face...
Typical power outputs of commercially available diode lasers are on the
order of 5 milliwatts. This thesis discusses the growth, processing and
fabrication of high power (lOO's of milliwatts) diode lasers. Devices were
grown by Molecular Beam Epitaxy (MBE) and by Metal Organic Chemical
Vapor Deposition (MOCVD). The MOCVD diode...
The role of the high density lipoprotein (HDL) molecule is currently an area of great interest within the scientific community. Previously, mouse and human studies have demonstrated an inverse association between HDL cholesterol (HDL-C) levels and cardiovascular disease. Recent clinical trials, which increased HDL-C, have failed to reduce the number...
