Polarized (3)He spin filters are needed for a variety of experiments with slow neutrons. Their demonstrated utility for highly accurate determination of neutron polarization are critical to the next generation of betadecay correlation coefficient measurements. In addition, they are broadband devices that can polarize large area and high divergence neutron beams with little gamma-ray background,...

The InterAsterisk eXchange (IAX) protocol has been available for a few years. Meanwhile, the popularity of Real time SWitching (RSW) has increased due to its ability to easily combine voice and video services. Incidentally, these two heterogeneous clients pose considerable problems for users who have to choose between two solutions offering different advantages and disadvantages. While RSW is b...

• In managing the Exchange Fund Account (EFA),* the Bank of Canada and the Department of Finance strive to limit the risks to which the Government of Canada is exposed in financing and investment operations that involve foreign currencies. • The EFA is exposed to various types of risk: credit risk, market risk, liquidity risk, operational risk, and legal risk. The approach used to manage them c...

BACKGROUND The National Hospital of Pediatrics in Vietnam performed >200 exchange transfusions annually (2006-08), often on infants presenting encephalopathic from lower-level hospitals. As factors delaying care-seeking are not known, we sought to study care practices and traditional beliefs relating to neonatal jaundice in northern Vietnam. METHODS We conducted a prospective, cross-sectional...

The procedure used to determine the pionnucleon coupling constant g(2) from multi-energy fits to nucleon-nucleon (N-N) scattering data has been shortened without a material loss of accuracy. The g(2) presetting effect is discussed in connection with the limited accuracy of g(2) determinations in general and the possibilities of the "optimized polynomial expansions". The desirability of the Yale...

BACKGROUND Australia is at a fork in the road with the possibility of a needle-syringe exchange program (NSP) to be introduced at the new prison in the ACT. However, the current situation is characterised by non-engagement from major stakeholders. We explore why informed discussion will not be enough to convince prison officers, policy makers and the wider community of the benefits of prison-ba...

Pharmacoeconomic/outcomes research (PE/OR) fellowships have been in existence for more than 10 years in response to the rising demand for expertise in economic evaluation.1-4 The first fellowship in PE/OR began in 19891; however, finding detailed information about these programs is difficult for several reasons. First, quantifying PE/OR programs is a challenge due to their increasing number in ...

BACKGROUND Persons who inject drugs (PWID) are at an elevated risk for human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infection. In many high-income countries, needle and syringe exchange programs (NSP) have been associated with reductions in blood-borne infections. However, we do not have a good understanding of the effectiveness of NSP in low/middle-income and transitional-eco...

Needle exchange programs (NEPs) are designed to prevent human immunodeficiency virus (HIV) transmission among injection drug users. Although most studies report beneficial effects in terms of behavior modification, a direct assessment of the effectiveness of NEPs in preventing HIV infection has been lacking. A cohort study was conducted to assess the association between risk behaviors and HIV s...

BACKGROUND Estonia has experienced an HIV epidemic among intravenous drug users (IDUs) with the highest per capita HIV prevalence in Eastern Europe. We assessed the effects of expanded syringe exchange programs (SEP) in the capital city, Tallinn, which has an estimated 10,000 IDUs. METHODS SEP implementation was monitored with data from the Estonian National Institute for Health Development. ...
