We demonstrate growth of epitaxial (100)SmN thin films directly on (100)Si surfaces. By using physical vapor deposition Sm metal in an ${\mathrm{N}}_{2}$ atmosphere we show that careful control substrate temperature, pressure, and postannealing steps leads to SmN without the formation samarium silicide impurity phases. While rare-earth competes with is favored over nitride at high temperatures,...

Since the 1980s cowpea has become an alternative cash crop in northern Senegal. However, in 1997, surveys showed that farmers often sold their crop at unprofi table prices. The hypothesis was that farmers could improve selling prices if they produced cowpea with the characteristics demanded by consumers. To identify those characteristics, data were collected in six markets from January 1998 to ...

lif, mg and ti cubical tld chips (known as tld-100) are widely used for dosimetry purposes. the repeatability of tl dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mgy) with 662kev photons of cs-137. a group of 40 cubical tld chips was randomly selected from a batch and the values of element correction coefficient (ecc) were obtained 4 times by irradiating them to doses...

This research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. To this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. Main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

In the West African sub-region, intercropping is a critical element in cowpea product profiles. This study aimed to investigate impact of with pearl millet on genetic correlations, heritability, and response selection. Thirty-five genotypes one variety were used create three cropping patterns: sole cowpea, 1:1 (one row cowpea), 2:4 (two rows four cowpea). Split-plot experiments conducted for tw...

The objective of this study was to examine the relationship between fluorescence emissions of corn kernels inoculated with Aspergillus flavus and aflatoxin contamination levels within the kernels. Aflatoxin contamination in corn has been a long-standing problem plaguing the grain industry with potentially devastating consequences to corn growers. In this study, aflatoxin-contaminated corn kerne...
