the study investigates consumers’ preference for cowpea reflected in the nigerian markets through price discounts and premiums that consumers pay for different cowpea characteristics. the price data used for this study were obtained through a market survey. a common data collection protocol was employed. every month, between october 2009 to december 2010, five cowpea samples per seller were bou...

Corn and cowpea from Kisar Island have been reported to nutritional content. With its content, it will be very useful if is combined into a cookies product that can developed especially for diabetics. In order used in the manufacture of cookies, necessary know correct formulation between corn flour flour, local varieties South West Maluku District, also organoleptic value corn-cowpea products. ...

The purpose of the study was to determine proximate composition and acceptability prepared pizza made with wheat, maize, cowpea flour blends. Five types were wheat flour, maize as main ingredients. sensory properties samples varied formulas, such 100:0:0, 90:6:4, 80:13:7, 70:18:12, 60:25:15%. As a control, entirely used. protein content composite ranged from 12.14 12.92%, moisture 12.59 12.82%,...

Combinations of winter and fall cover crops were evalu­ ated for the management of plant-parasitic nematodes. The winter cover crops examined were rye (Secale cereale) and narrow-leafed lupin (Lupinus angustifolius) and the fall cover crops were soybean (Glycine max), cowpea (Vigna unguiculata), sorghum-sudangrass (Sor­ ghum bicolor x S. sudanense), sun hemp (Crotalaria juncea), and corn (Zea m...

Using electron energy loss spectroscopy, we have probed the spin waves of fcc(100) cobalt after capping with 1–3 atom layers of pseudomorphic nickel or up to 12 atom layers of copper. The intensity decay of the spin wave signal is quantitatively described by the mean-free path of the incident and the scattered electron within the capping layer. The observed spin waves are therefore localized at...

A high-current, wide-band transconductance amplifier is described that provides an unprecedented level of output current at high frequencies with exceptional stability. It is capable of converting a signal voltage applied to its input into a groundreferenced output rms current up to 100 A over a frequency range from dc to 100 kHz with a useable frequency extending to 1 MHz. The amplifier has a ...
