Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Sludge thickening in a wastewater treatment plant using a modified hydrocyclone

Carbon Resources Conversion, 2021
The main application of hydrocyclones in most industry sectors is the separation of particles from liquids. For thickening, however, the separation properties of the cyclone should be adjustable, which requires a different operating mode.
