Many radioactive nuclei relevant for gamma-ray astrophysics are synthesized during explosive events, such as classical novae and supernovae. A review of recent results of explosive nucleosynthesis in these scenarios will be presented, with a special emphasis on the ensuing gamma-ray emission from individual nova and supernova explosions. The influence of the dynamic properties of the ejecta on ...

In 1996 six hospitals in Halifax, Nova Scotia, merged to become the Queen Elizabeth II Health Sciences Centre. The largest adult academic health sciences centre in Atlantic Canada, the QEII Health Sciences Centre occupies 10 buildings on two sites and provides tertiaryand quaternary-care services for patients across Nova Scotia. In 2000 it became part of the province’s Capital District Health A...

We show that dwarf nova disks in quiescence have rather low magnetic Reynolds number, of order 10. Numerical simulations of magnetized accretion disks suggest that under these conditions magnetohydrodynamic turbulence and the associated angular momentum transport is sharply reduced. This could be the physical origin of episodic accretion in dwarf nova disks. If so, the standard disk instability...

New observations of the eclipsing nova V1494 Aql were analysed in order to estimate the effect of the optical companion located 1. ′′4 southwest. R and I-band images (stellar FWHM ≈ 1. ′′2 − 1. ′′4) taken close to the primary minimum were used to determine relative magnitude differences between the nova and the companion, which were found to be ∆R ≈ 0. m20 and ∆I ≈ 0. m52 (in the sense nova min...

Ensuring reliability as the electrical grid morphs into the “smart grid” will require innovations in how we assess the state of the grid, for the purpose of proactive maintenance, rather than reactive maintenance; in the future, we will not only react to failures, but also try to anticipate and avoid them using predictive modeling (machine learning and data mining) techniques. To help in meetin...

We present a model for the high-low state transition of the X-Ray Nova GS 112468 (Nova Muscae 1991) observed by Ginga. The model consists of an advectiondominated accretion flow (ADAF) near the central black hole surrounded by a thin accretion disk. During the rise phase of the outburst, as the mass accretion rate increases, the transition radius between the thin disk and the ADAF moves closer ...

We present Hα direct imaging and shell spectroscopic observations of two classical novae: FH Ser 1970 and QU Vul 1984. The distances, reddenings, luminosities at maximum, and the mass of the shell ejected by FH Ser are derived and discussed.
