Long-term browsing impact around diversionary feeding stations for moose in Southern Norway
Forest Ecology and Management, 2010 Diversionary winter feeding of browsing ungulates is an increasingly common management practice although evidence for its efficacy to reduce excessive browsing remains ambiguous. Moreover, comparative estimates on changes in browsing pressure (proportion

Feeding order of sows at an individual electronic feed station in a dynamic group-housing system
Applied Animal Behaviour Science, 1993Abstract Patterns, in the use of a feed station, by sows, in a dynamic group-housing situation, were studied because deviations from such patterns might indicate disease, oestrus, reproductive or other problems. Groups of ten sows of various parities were transported to our experimental farm on the day their piglets were weaned.

Multifrequency band earth station feed design
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990The authors present a dual-polarized frequency reuse feed that not only operates in the C-, X-, and Ku-bands but also has significantly extended bandwidths, >800 MHz in C-band and >1.5 GHz in Ku-band. Design issues are discussed, and measurement results are presented. The feed was retrofitted on a 13-m Cassegrain antenna.
