Publikováno v: Theriogenology. 47:1327-1336

A copper-bearing intrauterine device (IUD), designed to cause a slight distention of the uterus, was inserted through the cervix into each uterine horn of 230 heifers; an additional 230 heifers served as the control group. Blood was drawn at 0, 1, 2,

Vibrational study and semiempirical calculation for the hexaazacyclophane copper(II) complex

Autor: M.M Campos-Vallette, R.E Clavijo C, F Mendizabal, G Diaz F, J Costamagna, J Canales, J Vargas

Publikováno v: Vibrational Spectroscopy. 14:71-78

The FTIR and Raman spectra of the hexaazacyclophane Cu(II) complex were recorded, and analyzed from a normal coordinate treatment by using an extended number of internal coordinates. The CuN force constant equal to 1.0 mdyn A −1 represents satisfac

Publikováno v: American Journal of Primatology. 34:19-28

We have investigated the role of the utero-ovarian ligament (UOL) in the alternating ovulatory performance of the ovaries in the capuchin monkey. In intact animals, the ovulation rate was near 90%, with 67.5% of ovulations occurring in the left ovary
