This research provides an investigation to measure the rate of corrosion steel bars coated with organic inhibitor Lawsonia inermis (Henna) and inorganic Sodium Nitrite (NaNO2) embedded in concrete. Presence on reinforcement reduces bond strength between concrete over a while excessive bar can lead loss ductility, extreme cases collapse. Structures like marine structures, sewage pipes, which are...

Objectives: This study aimed to examine the effect of ethanolic extract local Basra henna leaves on Gram-positive bacteria species. Also, assess antibacterial properties crude in vitro and compare them with antibiotics. Methods: In this study, Lawsonia inermis (henna) were extracted ethanol using solvent extraction technique. The pathogens isolated from wound samples obtained hospitalized patie...
