1Enamel microabrasion: An overview of clinical and scientific considerations显示文摘Superficial stains and irregularities of the enamelare generally what prompt patients to seek dental intervention to improve their smile. These stains or defects may be due to hypoplasia, amelogenesis imperfecta, mineralized white spots, or fluorosis, for which enamel microabrasion is primarily indicated. Enamel microabrasion involves the use of acidic and abrasive agents, such as with 37% phosphoric acid and pumice or 6% hydrochloric acid and silica, applied to the altered enamel surface with mechanical pressure from a rubber cup coupled to a rotatory mandrel of a lowrotation micromotor. If necessary, this treatment can be safely combined with bleaching for better esthetic results. Recent studies show that microabrasion is a conservative treatment when the enamel wear is minimal and clinically imperceptible. The most important factor contributing to the success of enamel microabrasion is the depth of the defect, as deeper, opaque stains, such as those resulting from hypoplasia, cannot be resolved with microabrasion, and require a restorative approach. Surface enamel alterations that result from microabrasion, such as roughness and microhardness, are easily restored by saliva. Clinical studies support the efficacy and longevity of this safe and minimally invasive treatment. The present article presents the clinical and scientific aspects concerning the microabrasion technique, and discusses the indications for and effects of the treatment, including recent works describing microscopic and clinical evaluations.Núbia Inocencya Pavesi Pini Daniel Sundfeld-Neto Flavio Henrique Baggio Aguiar Renato Herman Sundfeld Luis Roberto Marcondes Martins José Roberto Lovadino Débora Alves Nunes Leite Lima 2015World Journal of Clinical Cases2015,3,1:6
21998年印度洋珊瑚死亡事件的生态影响和社会经济影响:是ENSO影响和未来变化的警告吗?显示文摘自大约15O年前开始有气温记录以来,1998年是所记录到的最热的一年,20世纪90年代是最热的十年。另外,1998年也是有记录以来厄尔尼诺现象最严重的一年。这一现象产生的结果是,海洋中许多地方的水温很高,尤其是位于热带的印度洋的水温常常比正常年份高3~5℃。该区域内的大量珊瑚脱色并死亡,可能是由于高的水温以及其它气象、气候因子共同作用所致。斯里兰卡、马尔代夫、印度、肯尼亚、坦桑尼亚和塞舌尔群岛的珊瑚礁中珊瑚的死亡率较高,许多浅海区甚至高达90%。在位于印度洋其它地方和距海面20米以下的珊瑚礁中,珊瑚的死亡率通常为50%。因此,1998年珊瑚的死亡情况是空前严重的。印度洋的珊瑚褪色对沿海社区的二级社会经济影响可能是长期的和严重的。除了鱼资源可能减少和对旅游造成不良影响外,侵蚀可能成为一个严重的问题,尤其是在马尔代夫和塞舌尔群岛。如果目前已经发现的全球温度升高的趋势继续下去,那么1998年印度洋珊瑚礁上发生的情况在未来一些年内极有可能加剧并在其它的热带海洋区出现。印度洋的珊瑚礁可能是反映全球气候变化潜在影响的一个重要信号,我们应当对这一警告引起注意。Clive Wilkinson OlofLindén Herman Cesar Gregor Hodgson Jaston Rubens Alan E.Strong 李岱青 1999人类环境杂志1999,28,2:4
3Review on modelling of corrosion under droplet electrolyte for predicting atmospheric corrosion rate显示文摘Atmospheric corrosion of metals is the most common type of corrosion which has a significant impact on the environment and operational safety in various situations of everyday life.Some of the common examples can be observed in land,water and air transportation systems,electronic circuit boards,urban and offshore infrastructures.The dew drops formed on metal surface due to condensation of atmospheric moisture facilitates corrosion as an electrolyte.The corrosion mechanisms under these droplets are different from classically known bulk electrolyte corrosion.Due to thin and non-uniform geometric thickness of the droplet electrolyte,the atmospheric oxygen requires a shorter diffusion path to reach the metal surface.The corrosion under a droplet is driven by the depletion of oxygen in the center of the droplet compared to the edge,known as differential aeration.In case of a larger droplet,differential aeration leads to preferential cathodic activity at the edge and is controlled by the droplet geometry.Whereas,for a smaller droplet,the oxygen concentration remains uniform and hence cathodic activity is not controlled by droplet geometry.The geometry of condensed droplets varies dynamically with changing environmental parameters,influencing corrosion mechanisms as the droplets evolve in size.In this review,various modelling approaches used to simulate the corrosion under droplet electrolytes are presented.In the efforts of developing a comprehensive model to estimate corrosion rates,it has been noted from this review that the influence of geometric evolution of the droplet due to condensation/evaporation processes on corrosion mechanisms are yet to be modelled.Dynamically varying external factors like environmental temperature,relative humidity,presence of hygroscopic salts and pollutants influence the evolution of droplet electrolyte,making it a complex phenomenon to investigate.Therefore,an overview of available dropwise condensation and evaporation models which describes the formation and the evolution of droplet geometry are also presented from an atmo s pheric corrosion viewpoint.Bangalore Gangadharacharya Koushik Nils Van den Steen Mesfin Haile Mamme Yves Van Ingelgem Herman Terryn 2021Journal of Materials Science & Technology2021,,3:3
