X-ray observations of pulsar wind nebulae: The nature of pulsar winds and their environment
(2020-03-31)Pulsar wind nebulae (PWNe) are non-thermal bubbles blown by the relativistic winds of rapidly rotating neutron stars. They are formed in the cavity evacuated by the explosion of a core collapse supernova, and depending on ... -
X-ray observations of the young pulsar wind nebula G21.5–0.9 and the evolved pulsar wind nebulae CTB 87 (G74.9+1.2) and G63.7+1.1
(IOP Publishing Ltd. for The American Astronomical SocietyIOP Publishing Ltd. for The American Astronomical SocietyIOP Publishing Ltd. for The American Astronomical Society, 2010)Pulsar wind nebulae (PWNe), nebulae harbouring a rotation-powered neutron star that was born in a supernova, provide opportunities to study highly relativistic pulsar winds and their interaction with the surrounding medium. ... -
An X-ray powder examination of some pegmatite minerals from Southeastern Manitoba
(1963)This thesis describes the results of an investigation by means of X-ray diffraction powder photographs of the minerals from the pegmatites of southeastern Manitoba. These pegmatites are located in an area that is about 100 ... -
X-ray studies of highly magnetized neutron stars and their environs
(Astrophysical Journal LettersAstrophysical Journal, 2008)Supernova explosions are among the most energetic events known in the universe, leaving supernova remnants (SNRs) as their relics. The cores of massive stars collapse to form neutron stars, among the most compact and ... -

XRD Fibre Mounting Fixture Final Design
(2014-12-01)The design team was tasked by the Composites Innovation Center (CIC) to design a fixture that would improve the quality and effectiveness of the fibre sample mounting process of its X-Ray Diffractometer (XRD). Additionally, ... -
Yang-Mills flow in 1+1 dimensions coupled with a scalar field
(2015-01-07)We define a Yang-Mills model in 1+1 dimensions coupled to a real scalar field and we study the Yang-Mills flow equations for this simple model. Yang-Mills flows have not been thoroughly studied, especially in a physical ... -
YEAST PRODUCTS AS POTENTIAL SOURCES OF IMMUNOMODULATORY AND GROWTH PROMOTING ACTIVITY FOR BROILER CHICKENS
(2015)The use of antibiotic growth promoters has been limited all around the world because of the concerns about antibiotic resistant bacteria and the presence of antibiotic residues in poultry products. Yeast-derived products ... -
