SUMMARY The epidemiological, clinical and pathological features of a disease syndrome in adult cattle grazing woolly-pod vetch (Vicia villosa ssp dasycarpa) or popany vetch (V benghalensis) are reported. Outbreaks of toxlcosis occurred between midwinter and midsummer in 3 dairy and 6 beef herds on the north coast of New South Wales, between 1982 and 1992. Friesian, Angus, Murray Grey, Guernsey and Hereford breeds were affected. Mean morbidity and case fatality rates in affected herds were 7% (65 of 889) and 69%, respectively. Signs of pruritic dermatitis, illthrift and death were associated with an eosinophilic granulomatous inflammation of many organs, particularly involving the renal cortex, dermis, myocardium, adrenal glands, lymph nodes and hepatic portal triads. 相似文献

A modified version of the Ontario Ministry of the Environment Statistical Long-Range Transport (LRT) Model has been developed at the University of Waterloo. The model incorporates wind rose data at pollutant sources and receptors to reflect the percent of time that a source pollutant plume is affecting a down-wind receptor. Comparison of output to results generated by complex LRT models (i.e., the AES and MOE Lagrangian models) has demonstrated that the modified model results replicate complex model results fairly well. However, the model presented preserves the advantages of low execution costs and simple data input. This benefit permits the user to efficiently simulate a large number of LRT scenarios. 相似文献

Peridotite xenoliths from the Cascade arc in the United States and in the Japan arc have neodymium and osmium isotopic compositions that are consistent with addition of 5 to 15 percent of subducted material to the present-day depleted mantle. These observations suggest that osmium can be partitioned into oxidized and chlorine-rich slab-derived fluids or melts. These results place new constraints on the behavior of osmium (and possibly other platinum group elements) during subduction of oceanic crust by showing that osmium can be transported into the mantle wedge. 相似文献
