abstract objective cardiac dysfunction is a major cause of death in patients with beta thalassemia. in these patients, repeated blood transfusion, ineffective erythropoiesis and increased gastrointestinal iron absorption lead to iron overload in the body and this induced heart failure. left ventricular ejection fraction was measured in major beta thalassemia (β-th) patients to detect the relati...

in this work, artificial neural network (ann) was utilized to develop a new model for the predictionof the kinematic viscosity of petroleum fractions. this model was generated as a function oftemperature (t), normal boiling point temperature (tb), and specific gravity (s). in order to developthe new model, different architectures of feed-forward type were examined. finally, the optimumstructure...

in order to know the environmental behaviour of toxic pollutants it is fundamental to understandthe role of chemical components of a material on sorption of such pollutants.in this study, the sorption of amix of polycyclic aromatic hydrocarbons (pahs) by cork fractions (i.e. raw cork (cf), free extractive cork(fef) and nonsaponifiable (desf)) has been investigated to better understand the role ...

rosa damascena has been found to act on central nervous system including the brain. several studies confirm that r. damascena inhibits the activity of the hypothalamus and pituitary systems in rat and can suppress the central nervous system. in traditional medicine hypnotic effect of rose is also suggested. in this study, the hypnotic effect of the ethanol crude extract of r. damascena and its ...
