Effect of time of artificial insemination after oestrus detection on non-return rate of lactating dairy cows on pasture

New Zealand Veterinary Journal, 2016
To determine the difference in reproductive performance between cows detected in oestrus during morning or afternoon milking when artificial insemination (AI) was carried out once daily, either after the morning or afternoon milking.The study used 20,816 records for cows in 30 spring calving dairy herds that used a camera-based system for oestrus ...

Experimental Bit Error rate penalty evaluation of ring resonators filters on non return to zero transmission systems

2004
The paper discusses an experimental investigation of the impact of a single ring resonator and a double ring resonator filter on the performance of an optical communication Non Return to Zero system at 2.5 and 10 Gbit/s. Bit Error Rate curves are reported and discussed.
