Naturally fauna-free crossbred rams approximately 5 mo old, 49.3 +/- 1.88 kg live weight, were allotted to four groups. Two groups remained fauna-free, whereas the other two groups were faunated. A diet based on corn silage-soybean meal containing either a low or a high Cu concentration (7 or 15 micrograms/g dry matter) was fed ad libitum to the two groups for 197 d. The rams were killed at the...
The pyridine-coordinated Cu(II) atom in the title Schiff base complex, [Cu(C(15)H(11)N(3)O(5))(C(5)H(5)N)], is O,N,O'-chelated by the doubly deprotonated Schiff base ligand. The metal centre is in a square-planar coordination geometry.
Surface functionalization of SBA-15 followed by its reaction with Cu(OAc)(2) has been carried out to develop a new Cu-grafted functionalized mesoporous material, which catalyzes one-pot three component coupling of different aryl halides with thiourea and benzyl bromide in aqueous medium to produce aryl thioethers in very good yields (80-88%).
the 2-(methylamino) pyridine, l, reacts with cucl in thf to give hexameric copper (i) complex, [cucl(l)]6. the molecular structure has been determined by using single-crystal x-ray diffraction method. the complex crustallizes in the monoclinic space group p21/n with four molecules per unit cell. the unit cell dimensions are a = 8.3495 (15), b = 15.622 (6), and c = 17.030(4) å with b= 98.55 (2)°...
یکنواختی توزیع آب (cu) یک پارامتر مهم فنی در طراحی سیستم های آبیاری می باشد و مقدار آن تاثیر مهمی بر کیفیت و بازده سرمایه گذاری در پروژه های آبیاری دارد. اندازه گیری cu در آبیاری بارانی ثابت از روی نتایج یک آبپاش منفرد با توجه به در نظر گرفتن هم پوشانی آبپاش های مجاور و در مقادیر مختلف فشار کارکرد آبپاش (p)، ارتفاع پایه آبپاش (hr)، فاصله آبپاش ها روی لوله های جانبی (sl) و فاصله لوله های جانبی ا...
Yue X., Hu L., Fu X., Lv M., Han X. (2017): Dietary chitosan-Cu chelate affects growth performance and small intestinal morphology and apoptosis in weaned piglets. Czech J. Anim. Sci., 62, 15–21. The effects of dietary chitosan-copper chelate (CS-Cu) on growth performance, diarrhea, intestinal morphology and epithelial cell apoptosis in weaned piglets was investigated. One hundred and sixty Dur...
