Field Pea Grain for Beef Cattle
Price will dictate inclusion rates, but increasing availability of this grain legume is resulting in pricing that is competitive with other feeds. In creep feeds, 30 percent to 50 percent field peas appears to be optimum for animal performance. Commercial feed manufacturers are including peas in a number of commercial products for their nutrient density, palatability and competitive price, and ...
متن کاملField-dependent AC susceptibility of itinerant ferromagnets
Whereas dc measurements of magnetic susceptibility, χ, fail to distinguish between local and weak itinerant ferromagnets, radio-frequency (rf) measurements of χ in the ferromagnetic state show dramatic differences between the two. We present sensitive tunnel-diode resonator measurements of χ in the weak itinerant ferromagnet ZrZn2 at a frequency of 23 MHz. Below Curie temperature, TC ≈ 26 K, th...
متن کاملER effects in an ac applied field
The electric field used in most electrorheological (ER) experiments is usually quite high, and nonlinear ER effects have been theoretically predicted and experimentally measured recently. A direct method of measuring the nonlinear ER effects is to examine the frequency dependence of the same effects. For a sinusoidal applied field, we calculate the ac response which generally includes higher ha...
متن کاملThe Effect of Orobanche crenata Infection Severity in Faba Bean, Field Pea, and Grass Pea Productivity
Broomrape weeds (Orobanche and Phelipanche spp.) are root holoparasites that feed off a wide range of important crops. Among them, Orobanche crenata attacks legumes complicating their inclusion in cropping systems along the Mediterranean area and West Asia. The detrimental effect of broomrape parasitism in crop yield can reach up to 100% depending on infection severity and the broomrape-crop as...
متن کاملDirect field oriented control scheme for space vector modulated AC/DC/AC converter fed induction motor
Abstract This paper investigates a Luenberger flux observer with speed adaptation for a direct field oriented control of an induction motor. An improved method of speed estimation that operates on the principle of speed adaptive flux and current observer has been proposed. An observer is basically an estimator that uses a plant model and a feedback loop with measured stator voltage and current....
