This paper extends the previous work of authors and presents a non-layered Finite Volume formulation for the elasto-plastic analysis of Mindlin-Reissner plates. The incremental algorithm of the elasto-plastic solution procedure is shown in detail. The performance of the formulation is examined by analyzing of plates with different boundary conditions and loading types. The results are illustrat...
Mechanical properties and stress-strain curves of Cu, Ag and Au single crystals are calculated using ab initio methods. Elastic and Plastic regions are scrutinized. Yield stress and slope of these curves can shed light on brittlenesss and ductility of these metals that prove Cu, despite its high ultimate tensile strength, is less ductile than Au and Ag. Analysis of topology of charge density a...
BACKGROUND This article aims to investigate current perceptions of beauty of the general public and physicians without a specialization in plastic surgery performing aesthetic procedures. METHODS A cross-sectional and interviewing questionnaire was administered to 290 people in Seoul, South Korea in September 2015. The questionnaire addressed three issues: general attitudes about plastic surg...
Commercial mushroom growth on substrate material produces a heterogeneous waste that can be used for bioenergy purposes. Hyperspectral imaging in the near-infrared (NHI) was used to experimentally study a number of spent mushroom substrate (SMS) packed samples under different conditions (wet vs. dry, open vs. plastic covering, and round or cuboid) and to explore the possibilities of direct char...
Hot solder dipping is an accepted method to mitigate whisker growth on electronic components plated with pure tin. To provide the best protection from tin whiskers, the solder coating needs to be up to the package body. The conventional wisdom for solder dipping maintains that dipping up to the package body can cause component damage. If the specific construction differences of ceramic and plas...
OBJECTIVE The undergraduate medical curriculum has been overcrowded with core learning outcomes with no formal exposure to plastic surgery. The aim of this study was to compare medical students from two educational settings for the basic understanding, preferred learning method, and factors influencing a career choice in plastic surgery. DESIGN AND SETTING A prospective cohort study based on ...
OBJECTIVE To describe the geographic and temporal trends in cosmetic facial plastic surgery procedure costs and frequency during the last decade and to evaluate factors that may influence changes in the demand for cosmetic procedures. METHODS A survey sent to every (N = 1727) active fellow, member, or associate of the American Academy of Facial Plastic and Reconstructive Surgery assessing the...
Achieving a level of technical skill and confidence in surgical operations is the main goal of plastic surgical training. Operating rooms were accepted as the practical teaching venues of the traditional apprenticeship model. However, increased patient population, time, and ethical and legal considerations made preoperation room practical work a must for plastic surgical training. There are sev...
BACKGROUND Exposure to plastic surgery during medical school is limited. Most interested applicants form their perceptions of careers in this surgical specialty during elective rotations. OBJECTIVE To investigate the perceptions of Canadian medical students considering a career in plastic surgery. The results obtained were then compared with current Canadian plastic surgery residents' percept...
