Aim: The objective of this study was to evaluate the effects of introducing Sugar Beet bulb as a cheap substitute for grains in rations formulated for sheep fattening. Materials and Methods: This trial was conducted at the Experimental unit of Rural Development and extension center, Faculty of animal production, University of Gezira. Twenty four Sudanese desert lambs (Ashgur ecotype) were purch...

in order to study the responses of grain yield of chickpea to drought stress and application methods of nitrogen fertilizer, an experiment carried out as split-plot at campus of agriculture and natural resources, razi university, kermanshah, iran, during 2009-10 and 2010-11. the supplementary irrigation at three levels (1. without irrigation, 2. one irrigation at flowering, 3. two irrigations a...

Dust grains — objects of different shapes with a size distribution from micro to nanometers — are generally considered as a part of many space as well as laboratory plasmas. Among various charging processes, electron-induced secondary emission plays an important role wherever plasma contains a noteworthy portion of hot electrons. We have developed a numerical model of charging dust grains due t...

The occurrence of grain boundary precipitates was investigated with respect to the crystallographic orientation adjacent grains in extruded AA6110, AA6063 and AA6061 alloys brought T6 temper. It found that requirement for precipitate formation is have <100>Al directions or {100}Al planes parallel plane. highest density present when this fulfilled by both grains.

Introduction The preliminary examination of Stardust samples has yielded a number of surprising findings, such as the presence of large refractory mineral grains, including materials resembling CAIs, chondrules, and AOA fragments [1-3]. Furthermore, intact organics and fine grained materials are unexpectedly rare in Stardust tracks [4,5]. The fact that intact fine grained materials are uncommon...

The unique nonuniform deformation characteristic of high-pressure torsion was used to produce nanostructures with systematically varying grain sizes in a copper disk, which allows us to study the grain-size effect on the deformation mechanisms in nanostructured copper using a single sample. The as-processed copper disk has 100–200 nm grains near its center and 10–20 nm grains at its periphery. ...

Weeds can cause serious damage during soybean development, due to allelopathy, competition for water, light and nutrients. It is necessary investigate the influence of straw, weeds Conyza spp. Digitaria insularis, in growth, production composition grains. If there allelopathic compounds at crop. The aim this study was evaluate straw maize Urochloa brizantha (A.Rich.) R.D.Webster crops spp., D. ...
