background: until now, trimodal distribution of hbs has been seen by six different studies in the world when associated with alpha-thalassemia with confirmation by corresponding alpha-genotyping studies. the rbc indices reduce as alpha-globin genes reduce in sickle cell trait (sct) patients, which decreases the extent of intra-vascular sickling and thus betters the clinical course of the patien...

Background: Until now, trimodal distribution of HbS has been seen by six different studies in the world when associated with alpha-thalassemia with confirmation by corresponding alpha-genotyping studies. The RBC indices reduce as alpha-globin genes reduce in sickle cell trait (SCT) patients, which decreases the extent of intra-vascular sickling and thus betters the clinical cou...

this paper deals with the investigation of the microstructure and hardness of steel samples cladded with satellite 6-wc composites by using gas tungsten arc welding (gtaw) process. for this purpose, steel samples were coated with unreinforced and reinforced stellite (by 20, 30 and 40 wt.% wc). the cladded samples were evaluated by metallographic studies, microhardness measurement and x-ray diff...

in this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. mechanical properties of micro and nano- composites, including tensile strength, elongation, and young’s modulus, before and after ageing, were determined and analyzed. for this purpose, micro- and nano-sized caco3 particles were used as fillers to prepare micro-composites (c...
