To estimate the reliability of ultrasound for the detection of colonic wall pathology induced by the intestinal parasitic helminth O. bifurcum, three studies to assess the intraand inter-observer variation of the technique were performed. In the endemic area of northern Ghana, 181 people from a low prevalence village and 62 people from a high prevalence village were examined twice by the same o...

Bovine infectious keratoconjunctivitis (BIK, pinkeye) is an economically important illness affecting growth of calves. The primary objective of this study was to estimate genetic parameters for BIK in beef calves prior to weaning. Health records of 47,880 calves born at the Meat Animal Research Center, Clay Center, NE from 1983 through 2001 were evaluated. Cows and calves were monitored daily f...

Work fluctuations and work probability distributions are fundamentally different in systems with shortranged versus long-ranged correlations. Specifically, in systems with long-ranged correlations the work distribution is extraordinarily broad compared to systems with shortranged correlations. This difference profoundly affects the possible applicability of fluctuation theorems like the Jarzyns...

The new antibiotic sarubicin A [red crystals, mp. 194 approximately 195 degrees C, C18H14N2O6 (I)] was isolated from fermentations of a Streptomyces strain. The compound is moderately active in vitro against Micrococcus luteus.

We report the observation of proximity effect in measurements performed on highly oriented pyrolitic graphite (HOPG) samples when electrical current is injected through superconducting electrodes placed sample surface few millimeters apart from each other. Such anomalously large surprising, as proximity-induced features normal conductors hardly surpass micrometers. The obtained results can be c...
