We demonstrated short segments of a superconducting wire that meets or exceeds performance requirements for many large-scale applications of high-temperature superconducting materials, especially those requiring a high supercurrent and/or a high engineering critical current density in applied magnetic fields. The performance requirements for these varied(More)
To circumvent drought conditions persisting during seed fill in the mid-south U.S. soybean production region, researchers have developed the early soybean (Glycine max [L.] Merr.) production system (ESPS), which entails early planting of short-season varieties. Because soybean supplies a preponderance of the world's protein and oil and consumption of(More)
High performance YBCO films have been realized through MOD approach by hybrid of Ba-TFA with TMAP (trimethylacetates with propionic). High I/sub c/ over 140 A/cm-w and high J/sub c/ up to 2.4 MA/cm/sup 2/ at 77 K for 0.6 /spl mu/m YBCO films on RABiTS have been shown on un-bridged and bridged samples. Texture characterizations performed in XRD four-circle(More)
We have developed a simplified buffer layer architecture for the rolling-assisted biaxially textured substrates (RABiTS) template approach. The overall purpose of this research is to enable potentially a low-cost, high throughput and high yield manufacturing processes for buffer fabrication and to gain fundamental understanding of the growth of buffer(More)
The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is a severe pest of soybean, Glycine max (L.) Merr., in the United States. Nematode reproduction and the seed yield losses caused by this nematode are influenced by soil texture (3,5,6). Todd and Pearson (5) recovered higher numbers of SCN females and cysts from a sandy loam soil than from silty(More)
Soybean cyst nematode (Heterodera glycines Ichinohe) (SCN) a major pest of soybean [Glycine max (L.) Merr.] in the southeastern USA. The objective of this study was to determine the effect of wet and dry silt loam and clay soils on SCN development and corresponding soybean yield response in a greenhouse study. ’Tracy-M’ soybean was grown in pots that(More)
Slot die coating and conversion of La<sub>2</sub>Zr<sub>2</sub>O<sub>7</sub>(LZO) buffer layers were performed on rolling assisted biaxially textured Ni-W with and without thin Y<sub>2</sub>O<sub>3</sub> seed layers. The slot die coating, drying and processing were all performed using reel to-reel systems. The slot die coated LZO precursor films were then(More)
The rate at which thin film YBCO precursor converts to high J/sub c/ superconductor depends on many factors including the method by which the precursor is prepared, the precursor film thickness, and the conditions during precursor deposition and conversion. Using in-situ X-ray diffraction and reduced pressures, we have examined and compared conversion rates(More)
such as weeds must be prevented within economic constraints. In previous research at Stoneville, where Management inputs that maximize economic return from the early drought was common during the reproductive period soybean [Glycine max (L.) Merr.] production system (ESPS) in the midsouthern USA have not been evaluated fully. Field studies were of soybean,(More)
Critical current densities (J<sub>c</sub>) over 2 MA/cm<sup>2</sup> have been obtained for epitaxial NdBa<sub>2</sub>Cu<sub>3</sub>O<sub>7-delta</sub> (NdBCO) films deposited via pulsed laser deposition on RABiTS having the configuration of Ni - 3at.%W /Y<sub>2</sub>O<sub>3</sub>/YSZ/CeO<sub>2</sub>.
