1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Present study describes the length-weight (LWR) and length-length (LLR) relationships of a freshwater catfish Eutropiichthyes vacha Hamilton from Indus River, Sindh, Pakistan. A total of 281 specimen of E. vacha were collected from fisherman?s catch from February 2005 to January 2006, are used for this study. The parameters a and b of the length-weight relationship were calculated as W= aLb are...

on the circular curve, lateral acceleration affects comfort. on the spiral, both lateral acceleration and jerk affect comfort.  the determination of maximum curving speed on the basis of lateral acceleration only is not critical because the lateral acceleration is proportional to the square of speed whereas jerk is proportional to cubic power of speed. the maximum speed on a curve is thus signi...
