Of 109 aquatic birnaviruses (AB) belonging to 9 serogroup A, all replicated and produced rapid and extensive cytopathology in CHSE-214 and RTG-2 cells, whereas only half produced significant levels of cytopathological effect (CPE) in two nonsalmonid cell lines tested (EPC and FHM). In many instances it was found that although...
Blackberry pomace (BBP), a byproduct from juice processing, is often disposed of in landfills. We propose BBP as an antioxidant-rich feed supplement for transition dairy cows. To explore the effects of BBP on antioxidant status, 24 multiparous dairy cows (5 Holstein and 19 Jersey) were assigned randomly to one of...
Cognitive radio technology emerges as a promising solution for overcoming shortage and inefficient use of spectrum resources. In cognitive radio networks, secondary users, which are users equipped with cognitive radios, can opportunistically access spectrum assigned to primary users, the spectrum license holders. Although it improves spectrum utilization efficiency, this opportunistic...
This report examines environmental factors influencing the die-off and transport of fecal coliform bacteria present in wastes applied to the land surface. These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers the...
One hundred seventy-eight Agrobacterium isolates, 120 United
States (U.S.), 26 Australian and 32 of miscellaneous origin, were
characterized for their reactions to 20 biochemical and physiological
tests. Isolate pathogenicity and degree of host specificity, utilization
of nopaline and octopine, and sensitivity to agrocin-84 also were
determined. The U.S. isolates were...
The Willamette Valley of Oregon has high rates of winter precipitation that cause
leaching losses of residual fertilizer nitrogen (N) as nitrate (NO₃). Cover crops may have
potential to mitigate N loss. Shallow groundwater was sampled for 11 years from plots
planted in summer vegetables with and without winter cover...
