The seroprevalence and risk factors for exposure to Neospora caninum and Neospora hughesi in Ontario broodmares.

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.

Student Veterinarian Perceptions of Community-Based Primary Care Veterinary Clinics in Indigenous Communities in Southern Ontario, Canada.

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.

Is electromagnetic field momentum due to the flow of field energy?

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.

Understanding fuel magnetization and mix using secondary nuclear reactions in magneto-inertial fusion.

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.

Experimental demonstration of fusion-relevant conditions in magnetized liner inertial fusion.

This Letter presents results from the first fully integrated experiments testing the magnetized liner inertial fusion concept [S. A. Slutz et al.

Architecture, implementation, and testing of a multiple-shell gas injection system for high current implosions on the Z accelerator.

Tests are ongoing to conduct ~20 MA z-pinch implosions on the Z accelerator at Sandia National Laboratory using Ar, Kr, and D2 gas puffs as the imploding loads. The relatively high cost of operations on a machine of this scale imposes stringent requirements on the functionality, reliability, and safety of gas puff hardware. Here we describe the development of a prototype gas puff system including the multiple-shell nozzles, electromagnetic drivers for each nozzle's valve, a UV pre-ionizer, and an inductive isolator to isolate the ~2.

Is tubuloglomerular feedback a tool to prevent nephron oxygen deficiency?

The purpose of the study was to analyze whether rhythmic oscillations of proximal tubular pressure and distal fluid conductivity at the renal surface are induced by oxygen deficiency of thick ascending limb (TAL) segments. Oxygen pressure was measured in halothane anesthetized Munich-Wistar rats by a multi-wire micro-gold electrode at the kidney surface. Signals from wires placed upon glomeruli and tubuli exhibited pO2 oscillations with exactly the same frequency (in mean 30 mHz) as have been described for proximal tubular pressures or distal fluid conductivities.

Use of the umbilical area for placement of a urinary stoma.

Children with myelodysplasia are best managed in medical centers by a team consisting of a urologist, an orthopedist, a neurosurgeon, a pediatrician, a social worker, an orthotic technician and physical therapists. A co-operative approach aids in the selection of a urinary diversion stoma site which will not interfere with the multiple orthopedic procedures these children must undergo. The urologic and orthopedic complications and benefits of 24 patients with umbilical stoma are compared with 24 patients with matched right lower quadrant stoma.
