effect of bataine and sulphate supplement on wool and milk characteristics and lambs performance in naine ewes
تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولTHE EFFECT OF HEAT TREATMENT ON ABRASIVE WEAR RESISTANCE OF Fe-34Cr-4.5C%WT HARDFACING ALLOY
Abstract: Hardfacing is one of the most useful and economical ways to increase the service life of components subjected to abrasive wear. Iron based hardfacing alloys have long been considered as candidate coatings for wear-resistant applications in industry. In the present work two layer of Fe-34Cr-4.5C%wt hardfacing alloy was deposited on ASTM A36 carbon steel plates by SMAW method. The m...
متن کاملEffects of microstructure on native oxide scale development and electrical characteristics of eutectic Cu–Cu6La alloys
A combination of electron microscopy, focused ion beam and conductive atomic force microscopy techniques have been used to study the microstructure, oxide scale development, and electrical behavior of a Cu–9 at.% La alloy. The as-cast alloy exhibits a eutectic microstructure comprising 30 vol.% Cu rods in a Cu6La matrix. The eutectic colonies exhibit a singular orientation relationship with [01...
متن کاملWeld Procedural Effect on the Performance of Ferrous Based Hardfacing Deposit on Mild Steel Substrate
-Hardfacing is one of the most useful and economic ways to improve the performance of components submitted to severe wear conditions. A study was made to compare the microstructure and abrasion resistance of hardfacing alloys reinforced with primary chromium carbides, the hardfacing alloys were deposited onto M.S. plate by SMAW process. Two different commercial hardfacing electrodes were employ...
متن کاملRevealing heterogeneous nucleation of primary Si and eutectic Si by AlP in hypereutectic Al-Si alloys.
The heterogeneous nucleation of primary Si and eutectic Si can be attributed to the presence of AlP. Although P, in the form of AlP particles, is usually observed in the centre of primary Si, there is still a lack of detailed investigations on the distribution of P within primary Si and eutectic Si in hypereutectic Al-Si alloys at the atomic scale. Here, we report an atomic-scale experimental i...
