At the 13 AIDS Conference in Durban new data from the following randomized clinical trials on the use of antiretrovirals (ARVs) to prevent mother to child transmission were presented: • PETRA Trial (South Africa, Tanzania and Uganda) • Perinatal HIV Prevention Trial (Thailand) • ANRS/CDC pooled analysis West Africa (Côte d’Ivoire and Burkina Faso) • SAINT Study (South Africa) • HIVNET012 trial ...

In 2015, there were an estimated 729 517 people living with HIV in Ethiopia, including 95 094 children (aged 0–14 years), according to the 2015 Estimation and Projection Package/Spectrum modelling. HIV prevalence at the national level is 4.2% among urban populations and 0.6% rural populations; by gender, HIV prevalence is 1.52% among women and 1.0% among men.1 The HIV epidemic in Ethiopia is pr...

We have discovered nine presolar silicate grains from the carbonaceous chondrite Acfer 094. Their anomalous oxygen isotopic compositions indicate formation in the atmospheres of evolved stars. Two grains are identified as pyroxene, two as olivine, one as a glass with embedded metal and sulfides (GEMS), and one as an Al-rich silicate. One grain is enriched in 26Mg, which is attributed to the rad...

This paper deals with the automation of academic processes using workflow management systems. Current available workflows create lot of network traffic which leads to increase in network latency. The solution to this problem is to integrate mobile agents with workflow systems. Many researchers proposed and developed such systems but none of them consider the scenario of academic institution whi...

We revise and update SNO-STR-92-094 to identify and quantify sources of systematic uncertainty in determining the efficiency for detecting neutrons resulting from the neutralcurrent neutrino disintegration of deuterium. We conclude that aUowing for two standardized neutron sources (one strong, one weak) that can be moved vertically within the cylinder defined by projecting the vessel neck downw...

Introduction: Presolar silicate grains have been abundantly identified since their first discovery less than a decade ago [1,2,3]. The O isotopic compositions of both silicate and oxide stardust indicate the vast majority (>90%) condensed around O-rich asymptotic giant branch (AGB) stars. Though both presolar phases have average sizes of ~300 nm, grains larger than 1 μm are extremely uncommon f...

BACKGROUND AND PURPOSE We aimed to investigate the associations of dietary and total potassium, magnesium, and calcium intakes with stroke occurrence. METHODS A prospective cohort study was conducted among 36 094 participants aged 21 to 70 years. Dietary intake was assessed with a food frequency questionnaire. RESULTS During 12 years of follow-up, 631 strokes occurred. After adjustment for ...
