Marine Octocoral Phyllogorgia dilatata: Identification of Sesquiterpenes and Activity as a Natural and Renewable Corrosion Inhibitor

In the context of highly efficient, non-toxic and natural organic corrosion inhibitors, Phyllogorgia dilatata was studied as an anticorrosive for mild steel in acid medium. The marine octocoral crude extract (PDCE) was characterized and analyzed by LC-HRMS, revealing the presence of 16 different organic molecules. The corrosion inhibition was evaluated via weight loss study and electrochemical ...

Case Report: A 10-year-old girl presented moderate pain, recession in the mandibular right incisor and finger sucking habit. The performed treatment was: oral hygiene instruction, use of palatal...

An Efficiency Studying of an Ion Chamber Simulation Using Vriance Reduction Techniques with EGSnrc

Background: Radiotherapy is an important technique of cancer treatment using ionizing radiation. The determination of total dose in reference conditions is an important contribution to uncertainty that could achieve 2%. The source of this uncertainty comes from cavity theory that relates the in-air cavity dose and the dose to water. These correction factors are determined from Monte Carlo calcu...
