Following the intravenous injection of live Yersinia enterocolitica O:8, 50-69% of SHR rats developed arthritis; these rats were antibody free against all rat pathogens tested. In contrast, only 20-25% of SHR rats which had serum antibodies against Bacillus piliformis, Kilham rat virus, and Toolan H-1 virus developed arthritis. The results indicate that the microbial load of the host has a prof...

A significant step in the design of Heating, Ventilating, Air Conditioning, and Refrigeration (HVAC-R) systems is to calculate the room thermal loads which often vary dynamically. A self-adjusting method is proposed for real-time calculation of heating/cooling loads in HVAC-R applications. In this method, the heat balance calculations are improved by realtime temperature data to achieve more ac...
