1Liver transplantation:Fifty years of experience显示文摘Since 1963,when the first human liver transplantation(LT)was performed by Thomas Starzl,the world has witnessed 50 years of development in surgical techniques,immunosuppression,organ allocation,donor selection,and the indications and contraindications for LT.This has led to the mainstream,wellestablished procedure that has saved innumerable lives worldwide.Today,there are hundreds of liver transplant centres in over 80 countries.This review aims to describe the main aspects of LT regarding the progressive changes that have occurred over the years.We herein review historical aspects since the first experimental studies and the first attempts at human transplantation.We also provide an overview of immunosuppressive agents and their potential side effects,the evolution of the indications and contraindications of LT,the evolution of survival according to different time periods,and the evolution of methods of organ allocation.Alice Tung Wan Song Vivian Iida Avelino-Silva Rafael Antonio Arruda Pecora Vincenzo Pugliese Luiz Augusto Carneiro D'Albuquerque Edson Abdala 2014World Journal of Gastroenterology2014,20,18:8
2Morphing wing flaps for large civil aircraft:Evolution of a smart technology across the Clean Sky program显示文摘Abstract Morphing wing structures are widely considered among the most promising technologies for the improvement of aerodynamic performances in large civil aircraft.The controlled adaptation of the wing shape to external operative conditions naturally enables the maximization of aircraft aerodynamic efficiency,with positive fallouts on the amount of fuel burned and pollutant emissions.The benefits brought by morphing wings at aircraft level are accompanied by the criticalities of the enabling technologies,mainly involving weight penalties,overconsumption of electrical power,and safety issues.The attempt to solve such criticalities passes through the development of novel design approaches,ensuring the consolidation of reliable structural solutions that are adequately mature for certification and in-flight operations.In this work,the development phases of a multimodal camber morphing wing flap,tailored for large civil aircraft applications,are outlined with specific reference to the activities addressed by the author in the framework of the Clean Sky program.The flap is morphed according to target shapes depending on aircraft flight conditions and defined to enhance high-lift performances during takeoff and landing,as well as wing aerodynamic efficiency during cruise.An innovative system based on finger-like robotic ribs driven by electromechanical actuators is proposed as morphing-enabling technology;the maturation process of the device is then traced from the proof of concept to the consolidation of a true-scale demonstrator for pre-flight ground validation tests.A step-by-step approach involving the design and testing of intermediate demonstrators is then carried out to show the compliance of the adaptive system with industrial standards and safety requirements.The technical issues encountered during the development of each intermediate demonstrator are critically analyzed,and justifications are provided for all the adopted engineering solutions.Finally,the layout of the true-scale demonstrator is presented,with emphasis on the architectural strengths,enabling the forthcoming validation in real operative conditions.Rosario Pecora 2021Chinese Journal of Aeronautics2021,34,7:5
