Highly-evolved stars

The ways in which the IUE has proved useful in studying highly evolved stars are reviewed. The importance of high dispersion spectra for abundance analyses of the sd0 stars and for studies of the wind from the central star of NGC 6543 and the wind from the 0 type component of Vela X-1 is shown. Low dispersion spectra are used for absolute spectrophotometry of the dwarf nova, Ex Hya. Angular resolution is important for detecting and locating UV sources in globular clusters

Search for colliding stellar winds in Plaskett's star (HD 47129)

High dispersion spectra of Plaskett's star (HD 47129) were obtained with the short wavelength spectrograph on IUE at five phases of the binary cycle. The unsaturated wind profiles, particularly those of Si IV lambda 1400, show complex phase dependent structure. Two interpretations for the structure are suggested, neither of which is entirely satisfactory: (1) the structure is a consequence of directed streams, and (2) the structure is a consequence of colliding winds from the primary and secondary

Discovery of the molecular hydrogen ion (h2(+)) in the planetary nebulae

Low-dispersion spectra of fifteen planetaries and hot subdwarfs were obtained with the short wavelength prime camera on IUE and continuous flux distributions corrected for interstellar extinction were derived. Several planetaries, particularly the young planetaries of high surface brightness, show anomalous flux distributions. The most anomalous case is NGC 6210. These anomalies may be explained as absorption by H2+ H2(+) in the nebula

Geometric estimation of strains in car body panels

The thesis focuses on the manufacture of car body panels at Austin Rover and in particular the phenomenon of spring-back. After pressing of a shallow drawn panel its shape is often flatter than required. This loss of shape control corresponds to areas of small strains. The aim of the thesis is to describe the generation of a database of small strain information at discrete points on a drawn panel, which could be used in the numerical modelling of the drawing process.

OAO-2 observations of LY Aur

The eclipsing binary, LY Aur (09.5 III) was observed over a period of four days in March 1972 with the Wisconsin instrumentation on OAO-2. Complete light curves were obtained at the following wavelengths: 4250, 3320, 2980, 2460, 1910, and 1550 A. The phase resolution is usually 0.017. A solution of each light curve was attempted according to the Russell-Merrill method, but no solution was found

Canada, the G8 and the G20: A Canadian Approach to Shaping Global Governance in a Shifting International Environment

This paper reviews the history of the Group of Eight (G8) and the subsequent establishment of the Group of Twenty (G20).  It summarizes and analyzes the outcome of the most recent G8 and G20 Summits held in 2010 at Huntsville and Toronto respectively.  It takes stock of the G8/G20 summit processes, noting the emerging trends with respect to the role of Government Leaders, summit management and summit effectiveness. The paper concludes with a series of recommendations for a Canadian approach to influencing the rapid changes in international decision-making manifested by recent G8 and G20 experience. Chief among these suggestions is that Canada should lead work on resolving the relationship between the G8 and the G20 with a view to consolidating the G20 as a fully functioning instrument of global governance
