An experiment was conducted with 24 Arabi lambs to investigate the possibility to increase the utilization of wheat straw by ensiling with urea at rate of 1.5 % as a nitrogen source and to get the advantage of the additional digestion caused by the released ammonia, and molasses at rate of 10 % to encourage the fermentation responsible for silage making.(More)
This article presents a design of a printed antenna with simply shaped radiator element for multi-operating bands of the wireless communication systems. With a simple design configuration including different U shapes on a printed FR4 substrate, the proposed antennas covering the GPS (1575 MHz), Mobile-WiMAX (3400–3600 MHz) and 5 GHz WLAN(More)
An experiment was conducted with 20 Arabi lambs to study the effect of ensiling time on the nutritive value of wheat straw. Two silages containing 3% urea and 10% molasses, made at early and late summer, were compared in this experiment. Both silages were fed to lambs supplemented with two levels of concentrates. Results showed that ensiling straw at late(More)
