The wear of pipelines, used in slurry transport, results in high costs for maintenance and replacement. The wear mechanism involves abrasion, corrosion, impact, and the interaction among them. In this work, we study the effect of impact on the wear mechanism and wear rate. Results show that when the effect of impact is small, the wear mechanism is dominated by electrochemically induced surface ...

Introduction The clinical laboratory is regularly faced with the task of establishing the causes of non-diabetic melituria. These causes may be: physiological for neonates ], caused by hereditary defects of carbohydrate metabolism [2], brought about by congenital or acquired deficiencies of disaccharidases.[3], or an abnormal sugar excretion may be found with enteritis [4]. The necessary analys...

Corrosive ingestion is a rare but potentially devastating event and, despite the availability of effective preventive public health strategies, injuries continue to occur. Most clinicians have limited personal experience and rely on guidelines; however, uncertainty persists about best clinical practice. Ingestions range from mild cases with no injury to severe cases with full thickness necrosis...
