A system for sharing computer data between two or more sharing partners. A raw data value for a monitored characteristic of a network device or link is obtained by the management system and compared with a predetermined threshold value for the monitored characteristic. The light from the LEDs can then be combined to produce a desired illumination pattern. The pixels may be operated in linear and log modes sequentially, with the linear output being selected for low light signals and the log output being selected for high light signals. The apparatus also includes a supply device that supplies a pro-oxidant to the adsorption member. The present invention also relates to methods for increasing piglet weight gain and intestinal lactase activity.
