High Serum Ferritin Levels among Blood Transfused Thalassemic Patients Admitted to the Department of Paediatrics in a Tertiary Care Centre: A Descriptive Cross-Sectional Study.

Introduction: Raised serum ferritin levels often indicate iron overload, but they are not specific as the levels are elevated in inflammatory disorders, liver diseases, alcohol excess, or malignancy. If regular transfusions are required for the patient with thalassemia, this doubles the rate of iron accumulation leading to earlier massive iron overload and iron-related damage. The aim of this study aimed to find out the prevalence of high serum ferritin levels among blood-transfused thalassemic patients admitted to the Department of Paediatrics in a tertiary care centre.

Experimental testing of solar-based air heater roughed with discrete V-down rib and staggered element.

A rough rectangular channel of solar-based air heater (SBAH) is made and tested. The work consists of an effort to perceive the proportion of heat discharge and frictional behavior of air passing over a roughened rectangular channel. The absorber surface of SBAH is roughed with discrete V-down rib and staggered element roughness having different values of relative rib pitch (P/e) that ranged from 6 to 14.
