چکیده
The present study was conducted to evaluate the role of age in effectiveness intravaginal progestin-impregnated sponges (IPIS) along with equine chorionic gonadotropin (eCG) on multiple birth rates Awassi ewes. One hundred mature ewes (live weight 35–40 kg and 2–5 years) were allocated three groups according their ages (n = 29, 2-3 years;n 34, 3-4 years; n 37, 4-5 years). All impregnated IPIS, injected 20 mg cronolone, for 14 days, eCG (400 IU, i.m.) at withdrawal. treated came estrus (100%); highest twining rate recorded aged years, while triple found those years. A negative correlation coefficient between births. In conclusion, best synchronization programs outcomes using IPIS is 2–4

abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
