Although intensive research and prevention measures have been carried out for decades to control bovine mastitis, it continues to cause the biggest economic impact to the dairy industry worldwide. Severe economic losses, which are estimated to be approximately $200/cow/yr in the United States, are due to reduced milk production, discarded milk, replacement costs, extra labor, treatment, and vet...

A simple inviscid model to predict the onset of breakdown in an axisymmetric vortex is proposed. Three problems are considered: the shock-induced breakdown of a compressible vortex, the breakdown of a free compressible vortex, and the breakdown of a free incompressible vortex. The same physical reasoning is used in all three problems to predict the onset of breakdown. It is hypothesized that br...

In the last decades, a large focus is being placed on sustainability and safety of power transformer spectrum. Ester liquids, which have interesting properties such as high fire point biodegradability, are gaining needed attraction. Since in-service condition, thermal aging deteriorates physicochemical electrical liquid dielectrics, it important to study their long-term behavior. this contribut...
