The finite-element method is used to perform an accurate numerical study of the normal indentation of an elastic-plastic half-space by a rigid sphere. The effects of elasticity and strain-hardening rate of the half-space are explored, and the role of friction is assessed by analysing the limiting cases of frictionless contact and sticking friction. Indentation maps are constructed with axes of ...

In this study we develop a gradient theory of small-deformation single-crystal plasticity that accounts for geometrically necessary dislocations (GNDs). The resulting framework is used to discuss grain boundaries. The grains are allowed to slip along the interface, but growth phenomenona and phase transitions are neglected. The bulk theory is based on the introduction of a microforce balance fo...

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...

BACKGROUND Plastic surgery is the most competitive specialty in medicine. We sought to identify factors associated with the successful match of generation Y applicants into integrated plastic surgery residency. METHODS We utilized the most recent data from the Charting Outcomes in the Match published by the National Resident Matching Program in 2011. We had data on US senior or independent ap...

BACKGROUND The plastic surgery literature is vast, consisting of a plethora of diverse articles written by a myriad of illustrious authors. Despite this considerable archive of published material, it remains nebulous as to which precise papers have had the greatest impact on our specialty. The aim of this study was to identify the most cited papers in the plastic surgery literature and perform ...

Introduction. "See and treat" one-stop clinics (OSCs) are an advocated NHS initiative to modernise care, reducing cancer treatment waiting times. Little studied in plastic surgery, the existing evidence suggests that though they improve care, they are rarely implemented. We present our experience setting up a plastic surgery OSC for minor skin surgery and survey their use across the UK. Methods...

Cloud-based applications including Box, Dropbox, Google Drive, Evernote, Notability, and Zotero are available for smartphones, tablets, and laptops and have revolutionized the manner in which medical students and surgeons read and utilize plastic surgery literature. Here we provide an overview of the use of Cloud computing in practice and propose an algorithm for organizing the vast amount of p...

Although there have been cases of plastic surgery that date back to 2600 years ago, there has been a relatively recent upsurge in plastic surgery operations due to improved sterilization techniques and the advent of anesthesia [1]. Since plastic surgery operations were so rare until recently, teshuvos did not appear on the subject until about 60 years ago [1]. The topic of plastic surgery raise...

Over the last two decades, virtual reality, haptics, simulators, robotics, and other "advanced technologies" have emerged as important innovations in medical learning and practice. Reports on simulator applications in medicine now appear regularly in the medical, computer science, engineering, and popular literature. The goal of this article is to review the emerging intersection between advanc...

BACKGROUND Knowledge, perception, and acceptance of plastic surgery among any population are influenced by channel of presentation. A good understanding of the public awareness will define the way plastic surgery services will be provided. AIM To assess the knowledge, awareness of availability, and acceptance of plastic surgery practice in Enugu, South East Nigeria. MATERIALS AND METHODS A ...
