Abstract / Summary The market for US equity indexes has traditionally comprised floor-traded index futures contracts and the individual markets for the component stocks. This picture has been altere...

BACKGROUND Persons who use opioids have a high risk of overdose and associated mortality. In Vietnam, little is known about the characteristics of this population and the persons who are witness to those overdoses. One approach to combatting fatal overdose has been the use of peer interventions in which a friend or injecting partner administers overdose reversal medication, but availability in ...

where ∇pα denotes the radial pressure gradient, eZα the charge, nα the density and upol,α and utor,α the poloidal and toroidal rotation velocities of the species α . Bpol and Btor are the poloidal and toroidal magnetic field components determined from the magnetic equilibrium reconstruction. One of the most commonly used diagnostic to evaluate the ion quantities is active charge exchange recomb...

BACKGROUND "Knowledge exchange" (KE) refers to the interaction between knowledge users and researchers toward a goal of mutual learning and collaborative problem solving. METHODS Using a case study approach, this article describes how researchers leading a multiphase community engagement project, the Peel Cancer Screening Study (PCSS), used KE to engage a community advisory group (CAG) of kno...

The attempts to find the right (underlying) theory for the nuclear force have a long and stimulating history. Already in 1953, Hans Bethe stated that ”more man-hours have been given to this problem than to any other scientific question in the history of mankind”. In search for the nature of the nuclear force, the idea of sub-nuclear particles was created which, eventually, generated the field o...

In view of the many possible applications such as fuel cells and electrolysers, recent interest in novel anion exchange membranes (AEMs) has increased significantly. However, their low conductivity and chemical stability limits their current suitability. In this study, the synthesis and characterization of several three- and four-component anion exchange blend membranes (AEBMs) is described, wh...

The magnetic excitations of the double-exchange (DE) model are usually discussed in terms of an equivalent ferromagnetic Heisenberg model. However this equivalence is valid only at a quasi-classical level—we show that both quantum and thermal corrections to the magnetic properties of the DE model differ from any effective Heisenberg model because its spin excitations interact only indirectly, t...

During the mid-1990s, Vancouver experienced a well characterized HIV outbreak among injection drug users (IDU) and many questioned how this could occur in the presence of a high volume needle exchange program (NEP). Specific concerns were fuelled by early research demonstrating that frequent needle exchange program attendees were more likely to be HIV positive than those who attended the NEP le...

BACKGROUND A significant number of implantable cardioverter-defibrillator (ICD) patients do not experience shocks after ICD implant. Elective generator exchange (GE) has been associated with increased risk of infection and ICD lead failure. There is a paucity of contemporary data reporting on shock incidence with replacement devices. METHODS AND RESULTS Patients undergoing elective GE (n=24 2...

OBJECTIVES To determine the demographic characteristics, risk behaviours and prevalence of HIV-1 among injection drug users (IDU) attending Calgary's needle exchange program (NEP). METHODS A survey was conducted from June through September 1998 among IDU attending Calgary's NEP. Demographic and behaviour characteristics were determined by personal interview and saliva was tested for HIV antib...
