The macromolecular configuration of humic acid sample obtained from Farm Yard Manure was investigated by viscometric measurements at varying sample concentrations and in presence of a neutral electrolyte. The humic acid molecule behaved like a linear flexible colloid at lower sample concentrations and rigid rod like or sphereo-colloid polyelectrolyte at(More)
Clinical distinction between superficial and deep burns is problematic. The authors determined whether an infrared thermal imaging (IRTI) camera could predict burn depth. Burn depth was assessed by an experienced surgeon, and the burns were imaged with a portable, lightweight IRTI camera that measures heat emission from the skin using long infrared(More)
Burn therapies should focus on achieving outcomes that are most important to patients. The authors wanted to discover which outcomes newly burned patients would anticipate as most important to them and explored the association between demographic/burn characteristics and patient preferences. The authors surveyed 753 of 776 patients seen by our burn service(More)
OBJECTIVES The purpose of this study was to assess surgical availability and readiness in 8 African countries using the WHO's Service Availability and Readiness Assessment (SARA) tool. SETTING We analysed data for surgical services, including basic and comprehensive surgery, comprehensive obstetric care, blood transfusion, and infection prevention,(More)
Hepatobiliary radionuclide imaging is typically performed to detect cholecystitis. Infrequently, imaging reveals an obstructive pattern. Although delayed hepatobiliary imaging is commonly used to differentiate between intrahepatic (IH) and extrahepatic (EH) obstruction in the newborn; there is room to clarify the use of delayed imaging in the adult(More)
