Randomized controlled trials are the gold standard of evidence-based medicine. In the field of plastic surgery, designing these studies is much more challenging than in pharmaceutical medicine. Randomized trials in plastic surgery encompass several road blocks including problems shared with other surgical trials: equipoise, high cost, placebo issues and learning curves following the establishme...

Introduction: Ensuring maximum patient safety as well as a complete surgical experience is of utmost importance in training for plastic surgery. As plastic surgical training relies on resident participation in various procedures, we must guarantee adequate hands-on operative time while maintaining the best possible outcomes for the patient. The effect of resident involvement on the outcomes of ...

Injection molding has been the most popular method for making plastic products due to high efficiency and manufacturability. The injection molding process includes three significant stages: filling and packing stage, cooling stage, and ejection stage. Among these stages, cooling stage is very important one because it mainly affects the productivity and molding quality. Normally, 70%~80% of the ...

garlic (allium sativuml.) is one of the most important allium spice. from an economic point of view, the dried garlic slices are valuable products. in this research, garlic slices as a thin layer were dried in a laboratory scale hot-air dryer, under air flow of 1.5 m/s, air temperatures of 50, 60 and 70˚c and slice thicknesses of 2, 3 and 4 mm. the mean values of shrinkage of garlic slices obta...

BACKGROUND Many international volunteer groups provide free reconstructive plastic surgery for the poor and underserved in developing countries. An essential issue in providing this care is that it meets consistent guidelines for both quality and safety-a topic that has been addressed previously. An equally important consideration is how to provide that care in an ethical manner. No literature ...

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...

This paper presents the experimental results regarding acoustic emission signals measured during the injection molding of those standard test specimens commonly used for examining the shrinkage behaviour of various thermoplastic materials. In daily industrial production of different plastic products we often have to deal with various errors that practically occur on the mold primarily as a resu...

BACKGROUND Shrinkage of cutaneous tissue during processing is a source of controversy. This study was designed to prospectively determine tissue shrinkage at two intervals: 1 min after excision and after 24 to 48 h of formalin fixation. Secondarily, gender, age, site, prior biopsy scar and solar elastosis were evaluated with respect to shrinkage. METHODS Ninety-seven cutaneous specimens were ...

In this study, the setting and tensile strength development of ultra-high-performance concrete (UHPC) at a very early age was investigated by performing the penetration resistance test (ASTM C403), as well as the direct tensile test using the newly developed test apparatus, and taking ultrasonic pulse velocity (UPV) measurements. In order to determine the optimum surface treatment method for pr...
