Open Journal of Anesthesiology 2012年第3期2卷 59-61页

作者： samuel n. Blacker Tiffany E. Angelo Department of Anesthesiology Walter Reed National Military Medical Center Bethesda MD USA. Department of Anesthesiology Womack Army Medical Center Fort Bragg NC USA

The teratogenicity of thalidomide has been known since the early 1960s [1]. Thalidomide is currently used world wide, including the United States, to treat erythema nodosum leprosum, multiple myeloma, refractory Crohn’s disease, aphthous stomatitis and HIV wasting syndrome. new cases of thalidomide phocomelia are being reported as well. We report a case of the anesthetic challenges of a 23 year-old parturient with thalidomide phocomelia and review the important anesthetic challenges it presents. Spontaneous vaginal delivery under continuous lumbar epidural was achieved in this challenging patient. However, it required careful planning for reliable intravenous access and the use of magnetic resonance imaging (MRI) of her pelvis and lumbar spine.

伊博语是尼日利亚国内重要的一种语言,使用人口很多。随着尼日利亚伊语母语的汉语学习者的增加,越来越多的人注意到其母语语音系统与汉语语音系统的差异。但目前为止,还没有人对这两种语言的语音系统进行专门的对比研究。因此,对这两种语言进行语音系统的对比研究,有开拓性意义。同时,从对外汉语教学视角进行这两种语言的语音系统的对比研究,一方面可以发现伊语母语的汉语学习者汉语发音中的偏误问题,另一方面可以用于解释、指导对这些学习者的汉语语音教学。本论文基于作者伊博语母语者的感知,结合语音学理论、比较语言学理论以及运用praat软件的实验语音学研究方法,对伊博语和汉语的语音系统进行了对比研究以期能帮助伊语母语的汉语学习者更有效地习得汉语语音,同时也帮助汉语教师更好地了解伊博语语音系统,并帮助他们设计更好的教学方法。论文共分五章:第一章,绪论。介绍本论文的研究对象和范围、研究的意义与价值、文献综述、研究方法以及材料来源。第二章,伊博语概述及伊汉语语音系统的总体差异。对伊博语这一语言所属的语系、文字系统、语音系统及与汉语语系系统总体上的差异。第三章,具体对比了伊汉元音系统的相同和不同之处。伊博语有8个元音,汉语有10个基本元音,但汉语与伊语的元音,只有3个是相同的,其他几个是不同的。本章用praat软件做出了两种语言的元音图,展示其区别。第四章,具体对比了伊汉语辅音系统的不同。汉语有22个辅音,伊博语有28个辅音,两种语言的语音系统在发音部分和发音方法上都有差异。汉语的舌尖-齿龈后发音部分,伊博语没有;伊博语的齿龈后音发音部位,汉语没有。汉语的送气发音方法,伊博语没有;伊博语大量使用浊音,汉语则很少;伊博语的喉音、软腭音等,汉语也没有。本章用praat做了伊汉语语的辅音图,以展示其区别。第五章,对比了汉伊博语的声调和它的功能。伊博语有三个声调,汉语有四个声调,伊博语声调的调值与汉语声调不一样。本章用praat软件绘出了伊语声调的发音特点图。本章还描写了伊博语声调的几大功能。第六章,重点介绍了伊博语的成音节辅音,元音和谐和元音同化现象。这些都是伊博语特有的语音现象,汉语中都没有。第七章,结语。简要分析了伊语语音系统与汉语语音系统的差异所导致的伊语母语学生在学习汉语时,语音偏误的几类主要表现,伊博语学习者在初级阶段比较难学的汉语辅音是z[?]、c[?]、、zh[?]、z[?]、q[?]、x[?]。尤其是发送气音c[?]、q[?],因为伊博语没有送气与不送气的区别。

对地球陆地的卫星遥感大大增进了人们对全球植被型的了解.综合可见光与近红外波段的反射率观测值可以大致反映植被枝叶的存在,状况及数量.在气候研究中,这种资料相当有价值,因为气候变量与植被枝叶有关.植被枝叶的存在主要由局地热量与水分状况的结合决定.反过来,枝叶的存在又决定了局地光合率,影响表面反射率,影响局地蒸散率以及地面能量和质量平衡的其它要素.这些遥感资料的应用第一次为直接研究气候与植被之间的相互作用提供了连贯的全球性资料.这些进展正在被气候学研究接收,将会促进大尺度生物气候学的发展.预计在不久的将来,遥感技术以及人们对这些技术的了解将继续迅速发展,并且会推动卫星气候学这一新领域的重大进展.

China Foundry 2017年第6期14卷 525-533页

Dry sliding wear is one of the predominant factors to be considered while selecting material for automotive and aerospace applications. Researchers have been exploring novel aluminium matrix composites(AMC), which offer minimum wear rate for various tribological applications. In this present work, an attempt has been made to reinforce LM13 aluminium alloy with copper coated steel fibers(10 wt.%) using squeeze casting process and to perform dry sliding wear test using pin-on-disc tribometer. Microstructure of cast samples was examined using image analysis system to investigate the dispersion of reinforcement in matrix. Dry sliding wear test was performed by considering factors such as load(10–50 n), sliding velocity(1–5 m·s(-1)) and sliding distance(500–2,500 m). Wear test was performed according to the experimental design at room temperature. Three factors and five levels central composite design were used to design the experiments using response surface methodology. Based on the results of the experiments, a regression model was developed to predict the wear rate of composites and checked for its adequacy using significance tests, analyses of variance and confirmation tests. Worn surface of samples was investigated using field emission scanning electron microscope and reported with its mechanisms. Microstructure of cast samples revealed uniform dispersion of reinforcement throughout the matrix. Response surface plots revealed that wear rate of composites increases with increasing load up to 50 n with the velocity 1–5 m·s(-1) and a sliding distance up to 2,500 m. However wear rate decreasesd with increasing velocity at lower loads(up to 20 n) and increased after reaching transition velocity of 2 m·s(-1). Dry sliding wear process parameters were optimised for obtaining minimum wear rate and they were found to be a load of 18.46 n, velocity of 4.11 m·s(-1), sliding distance of 923 m. Worn surface of samples revealed a mild wear at lower loads(up to 30 n), and severe w

Open Journal of Orthopedics 2015年第10期5卷 305-310页

作者： L. Senthil n. Jambu B. samuel Chittranjan Department of Orthopaedics Sri Ramachandra University Chennai India

Plate osteosynthesis of humeral shaft fractures is an established surgical procedure. Iatrogenic radial nerve palsy appears to be common complication in treating these fractures. A case series of 20 fracture shafts of humerus were treated with anteromedial plating through anterolateral approach. There was no radial nerve palsy in any of the cases and all achieved fracture union.
