Comparative Study of Chemical Coagulation and Electrocoagulation for the Treatment of Real Textile Wastewater: Optimization and Operating Cost Estimation.

Pollutants derived from real textile wastewater present a high environmental risk. This work involves the study of the removal of chemical oxygen demand (COD), color, and turbidity from Tunisian real textile wastewater by two different water treatment technologies: chemical coagulation (CC) and electrocoagulation (EC). A comparative study between these two methods was conducted based on the separation performance and operating cost (OC).

Atrial septal defect closure in adults: A ten-year experience.

Introduction: Atrial septal defects (ASD) constitute the most frequent congenital heart disease in adults and ostium secundum (OS) the most common type. Benefit of its closure in adulthood has long been controversial.

Aim: To evaluate outcomes of OS-ASD closure in adults.

Root verbascoside and oleuropein are potential indicators of drought resistance in olive trees (Olea europaea L.).

Polyphenols are constituents of all higher plants. However, their biosynthesis is often induced when plants are exposed to abiotic stresses, such as drought. The aim of the present work was to determine the phenolic status in the roots of olive trees grown under water deficit conditions.

[Left ventricular non-compaction: What should be known!].

Isolated non-compaction of the left ventricle (NCVG) is a rare congenital cardiomyopathy resulting from the shutdown of normal embryogenesis of the myocardium. Its main feature is the existence of many deep heart-related ventricular trabeculations, generally located at the level of the apex of the left ventricle. Diagnosis is based on echocardiography and magnetic resonance imaging (MRI), and may be difficult in the atypical forms.
