15-Deoxy-Δ12,14-prostaglandin J2 (15dPGJ2) has been recently proposed as a potent anti-inflammatory agent. However, the mechanisms by which 15dPGJ2 mediates its therapeutic effects in vivo are unclear. We demonstrate that 15dPGJ2 at micromolar (2.5–10 µM) concentrations induces the expression of heme…

The Deobandi `Ulama' of Jami`at al-`Ulum al-Islamiyya located in the largest city of Pakistan, Karachi, began publishing an Urdu, monthly journal by the name of Bayyinat in 1962 for the expressed purpose of refuting the views and arguments of their…

In this thesis, I describe how interactive journal writing was used to improve the understanding of mathematics, and to foster communication with two groups of remedial grade ten students. Mathematics is a gatekeeper course in high school, and students who…

The National Policies of Education in India have recognized the need for teacher professional development. However, science teachers continue to look for innovative methods to improve teaching. Through collaborative action research with four science teachers at a girls' school in…

This qualitative study investigates the consequences of advancing three preschoolers into kindergarten in the province of Quebec, where the derogation exemption enables younger children to start school before they reach the age of admission of five years by September 30th.…

Obtaining holographic volume gratings with high diffraction efficiencies that can be used under white light has been a serious problem for the polyvinyl alcohol-acrylamide-based photopolymers developed by other researchers. In this paper we propose to eliminate the residual monomer in…

In order to achieve a better understanding of the mechanisms of hologram formation and higher diffraction efficiencies in volume gratings stored in acrylamide based photopolymers, a crosslinker (N,N'methylene-bis-acrylamide) has been incorporated in the photopolymer to record holograms by pulsed laser…

Kogelnik's coupled-wave (CW) theory has been used for decades to predict the diffraction efficiency of volume diffraction gratings. Although this theory has been applied with success to volume diffraction gratings recorded under a great variety of experimental conditions, its predictions…

This paper analyzes the effect on the optimal value of a given linear semi-infinite programming problem of the kind of
perturbations which more frequently arise in practical applications: those which affect the objective function and the right-hand-side coefficients of the…

We describe an integrated project that includes theoretical, numerical and experimental studies designed to facilitate teaching the non-linear post-buckling of a cantilever column to undergraduate mechanical engineering students. We present the differential equation governing the behaviour of this mechanical system…
