INTRODUCTION: During the 2015–2016 academic year, plastic surgery residents accounted for nearly 4.2% of surgical residents and 0.8% of residents overall. While the number of residency programs and allotted residency positions in plastic surgery have been steadily increasing in recent years, little information exists regarding residents who are accepted for plastic surgery residency but never m...

INTRODUCTION The WHO Safer Surgery checklist has become an important component of perioperative safety. Our objective, was to determine the compliance of completing the checklist for paediatric emergency plastic surgery patients at our unit. METHODS An initial baseline was performed with 70 patients over two months at our unit. Following this, we raised awareness at an audit meeting and close...

Recovery of plastic waste is becoming crucial since the amount such increases continuously. The objective this study to investigate potential pyrolysis technique for recovery waste. In that frame, influence temperature (550°C or 600°C) on pure polypropylene (PP), polyethylene (PE), polystyrene (PS) and terephthalate (PET) was first studied. It shown whatever type polymer, aromatic compounds are...

Marine plastic debris has become a significant concern in ocean ecosystems worldwide. Little is known, however, about its influence on microbial community structure and function. In 2008, we surveyed microbial communities and metabolic activities in seawater and on plastic on an oceanographic expedition through the "great Pacific garbage patch." The concentration of plastic particles in surface...

The increasing amount of plastic littered into the sea may provide a new substratum for benthic organisms. These marine fouling communities on plastic have not received much scientific attention. We present, to our knowledge, the first comprehensive analysis of their macroscopic community composition, their primary production and the polymer degradation comparing conventional polyethylene (PE) ...
