This study was performed with growing chicken (14 to 56 d of age) to evaluate the effects of feeding them a barley or triticale-based diet. The treatments were corn diet (1) as a control, hulless barley diet with (5) or without (2) enzyme, triticale diet with (6) or without (3) enzyme and hulled barley diet with (7) or without (4) a commercial β-glucanase enzyme. In a digestibility trial, 21 ma...

"there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...
Chern-Simons electrodynamics in 2+1-spacetimes with torsion is investigated. We start from the usual Chern-Simons (CS) electrodynamics Lagrangian and Cartan torsion is introduced in the covariant derivative and by a direct coupling of torsion vector to the CS field. Variation of the Lagrangian with respect to torsion shows that ChernSimons field is proportional to the product of the square of t...
background : one of the most prevalent side effects of hemodialysis is intradialytic hypotension and its symptoms. using sodium profiles 3 and ultra filtration profile 3 and cold dialysate are the ways to overcome this problem. since none of these methods could control this complication lonely, this study was done to investigate the effect of combination of two methods on intradialytic hypotens...
the thesis has been arranged into five chapters and mainly concerned with the baer-invariant of groups which is the generalization of the schur-multiplier with respect to the variety of groups. chapter one is devoted to collect some notation and background information which are needed in the next chapters. its also contains some important statements which will be generalized in this thesis. cha...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
Interrill erosion can change during rainfall due to change of soil conditions. This research was carried out to investigate the temporal variation of interrill erosion in different soils under different rainfall intensities. For this purpose, laboratory experiments were carried out in three soil textures consists under three simulated rainfalls under slope of 10 percent in three replications...
