The seroprevalence and risk factors for exposure to Neospora caninum and Neospora hughesi in broodmares in Ontario were investigated. Sixty of the 219 (27.4%) study broodmares were seropositive for N.

Community-based primary care veterinary clinics represent an opportunity to benefit multiple populations. Student veterinarians are afforded the opportunity to build technical and non-technical professional skills, while underserved communities are provided with access to companion animal care. The Ontario Veterinary College (OVC), as with many other veterinary colleges across Canada and the United States, has hosted community-based primary care veterinary clinics, including in local Indigenous communities.

Momentum and energy conservation require electromagnetic field momentum and energy to be treated as physically real, even in static fields. This motivates the conjecture that field momentum might be due to the flow of a relativistic mass density (defined as energy density divided by the square of the speed of light). This article investigates the velocity of such a mass flow and finds a conflict between two different definitions of it, both of which originally seem plausible if the flow is to be taken as real.

Magnetizing the fuel in inertial confinement fusion relaxes ignition requirements by reducing thermal conductivity and changing the physics of burn product confinement. Diagnosing the level of fuel magnetization during burn is critical to understanding target performance in magneto-inertial fusion (MIF) implosions. In pure deuterium fusion plasma, 1.
