1Review of magnesium-based biomaterials and their applications显示文摘In biomedical applications,the conventionally used metallic materials,including stainless steel,Co-based alloys and Ti alloys,often times exhibit unsatisfactory results such as stress shielding and metal ion releases.Secondary surgical operation(s)usually become inevitable to prevent long term exposure of body with the toxic implant contents.The metallic biomaterials are being revolutionized with the development of biodegradable materials including several metals,alloys,and metallic glasses.As such,the nature of metallic biomaterials are transformed from the bioinert to bioactive and multi-biofunctional(anti-bacterial,anti-proliferation,anti-cancer,etc.).Magnesium-based biomaterials are candidates to be used as new generation biodegradable metals.Magnesium(Mg)can dissolve in body fluid that means the implanted Mg can degrade during healing process,and if the degradation is controlled it would leave no debris after the completion of healing.Hence,the need for secondary surgical operation(s)for the implant removal could be eliminated.Besides its biocompatibility,the inherent mechanical properties of Mg are very similar to those of human bone.Researchers have been working on synthesis and characterization of Mg-based biomaterials with a variety of composition in order to control the degradation rate of Mg since uncontrolled degradation could result in loss of mechanical integrity,metal contamination in the body and intolerable hydrogen evolution by tissue.It was observed that the applied methods of synthesis and the choice of components affect the characteristics and performance of the Mg-based biomaterials.Researchers have synthesized many Mg-based materials through several synthesis routes and investigated their mechanical properties,biocompatibility and degradation behavior through in vitro,in vivo and in silico studies.This paper is a comprehensive review that compiles,analyses and critically discusses the recent literature on the important aspects of Mg-based biomaterials.Nurettin Sezer Zafer Evis Said Murat Kayhan Aydin Tahmasebifar Muammer Koça 2018Journal of Magnesium and Alloys2018,6,1:38
2德国北部挪威云杉林可持续经营中期计划的实例分析显示文摘可持续森林经营理论为中期林业计划和收获调整提供了丰富的模型选择,其不同的方法可应用于各种特定的场合和不同经营类型。本文简要回顾了传统的森林计划方法,一种称为“多林分发展”的概念可以用于任意的经营系统,这个概念把森林看作由一系列林分组成,在每一个林分中可以预先制定多种经营措施的选项,每种选项都可以通过木材或其它产品以及消耗的资源计算出一个目标值。这种简单的概念可以应用到大量的不同森林经营场合,它为森林经营者制定切实可行的森林措施和评价森林经营计划提供方法。在本研究中,以德国北部一片包括21个小班的挪威云杉林班的一个中期计划为例,说明“多林分发展”这一经营系统在实际生产中的应用。每个小班具有不同的初始状态,每个小班预设了若干经营选项,根据小班的初始状态、生长模型为各种选项计算各时期的木材产出。在林班的水平上,经营目标方程包括两个组成部分:净现值和均衡木材收获值。用模拟退火的方法来优化总体目标方程值。优化的总体解决方案在为每个小班选定合适的经营选项的同时,在全林的水平上获得最优的经济和均衡产出组合。陈伯望 Klaus.von Gadow Frantiek Vilko Sofía Sánchez Orois 2006林业科学研究2006,19,5:4
3Effect of water matrices on removal of veterinary pharmaceuticals by nanofiltration and reverse osmosis membranes显示文摘This study explored the removal of five veterinary pharmaceuticals (VPs) (sulfamethoxazole (SMETOX), trimethoprim (TMP), ciprofloxacin (CIPRO), dexamethasone (DEXA) and febantel (FEBA)) from different water matrices (Milli-Q water, model water, tap water and real pharmaceutical wastewater using four types of nanofiltration (NF) membranes (NF90, NF270, NF and HL) and two reverse osmosis (RO) membranes (LFC-1 and XLE). All VPs were added to different water matrices at a concentration of 10 mg/L. Rejections of VPs and water flux were measured. The rejection increased with increase of molecular weight. The highest rejections were obtained with RO membranes (LFC-1, XLE) and tight NF (NF90) membrane. In general, the rejection of VPs was higher in model water and tap water than in Milli-Q water, but the water flux was lower. This was mainly explained by ion adsorption inside the membranes pores. Narrower pore size counteracted the effect of presence of low concentration of natural organic matter (NOM) in tap water. The NOM was assumed to enhance the adsorption of VPs onto membrane surface, increased the size exclusion and electrostatic repulsion also appeared during the transport. Investigated water matrices had influence on water flux decline due to their complexity.Davor Dolar Ana Vukovi Danijela Aperger Kreimir Kouti 2011Journal of Environmental Sciences2011,23,8:4
