The Low Energy Neutron Source (LENS) at Indiana University produced its first neutrons in late 2004, and has been engaged in a series of facility upgrades since that time. Among the important developments over the past two years have been the commissioning of klystron-based RF systems, the demonstration of beam peak proton beam currents of more than 20mA, and the low-power operation of a methan...

BACKGROUND Maternal death reviews is a tool widely recommended to improve the quality of obstetric care and reduce maternal mortality. Our aim was to explore the challenges encountered in the process of facility-based maternal death review in Malawi, and to suggest sustainable and logically sound solutions to these challenges. METHODS SWOT (strengths, weaknesses, opportunities and threats) an...

A facility has to be located within a given region taking two criteria of equity and efficiency into account. Equity is sought by minimizing the inequality in the inhabitant-facility distances, as measured by the sum of the absolute differences between all pairs of squared Euclidean distances from inhabitants to the facility. This measure meets the Pigou-Dalton condition of transfers, and can e...

OBJECTIVE Rural north-central Liberia has one of the world's highest maternal mortality ratios. We studied health facility birthing service utilisation and the motives of women seeking or not seeking facility-based care in north-central Liberia. DESIGN Cross-sectional community-based structured interviews and health facility medical record review. SETTING A regional hospital and the surroun...

During a 2-week period in August 2011, two patients in a long-term care facility in Miami-Dade County, Florida, had gastrointestinal symptoms; microscopic examination of stool specimens showed that both harbored Strongyloides stercoralis, an intestinal nematode. A subsequent chart review revealed an additional case within the facility 1 year earlier. Concerned about the possibility of an outbre...
