The inhibitive action of 2-mercaptobenzothiazole on the porosity of corrosion film formed on aluminum and aluminum-titanium alloys in hydrochloric acid solution.

2-Mercaptobenzothiazole (2-MBT) in a solution of 0.5 M HCl is an effective corrosion inhibitor for aluminum and aluminum-titanium alloys. Tafel polarization and electrochemical impedance spectroscopy (EIS) were employed to assess this heterocyclic compound's anticorrosive potential and complementary by scanning electron microscope (SEM) and calculating porosity percentage in the absence and presence of various inhibitor concentrations.

Laparoscopic supracervical hysterectomy compared with total abdominal hysterectomy.

Objective: To assess if laparoscopic supracervical hysterectomy (LSH) had any advantage over traditional total abdominal hysterectomy (TAH) carried out for benign conditions.

Methods: This prospective case control study was carried out between June 2005 and October 2006 in the Obstetrics and Gynecology Department of Zagazig University Hospitals, Zagazig, Egypt. Twenty-eight women operated upon by LSH were compared to 56 women who had undergone TAH.
