两个中国留学生在澳大利亚

多年以来，因为在澳大利亚生活、教书的缘故，我跟许多在这里学习的留学生交上了朋友，他们当中的许多人来自中国。现在，一些中国学生已经回国了，也有许多人仍然在澳大利亚生活着。留在澳大利亚的中国人出于不同的考虑:一些人为了事业机会，一些人因为喜欢当地的生活节奏，一些人为了在学业方面继续深造，一些人是因为自己跟当地人坠入爱河，结成家庭。这个群体在变化着，因为他们喜欢澳大利亚的生活。他们当中的一些人已经逐步融入澳大利亚式的生活、语言和文化。也有一些人与他们不同，一些留学生思乡心切，怀恋故乡的文化、故乡的语言…     

同是英语却不同

什么是英语？英语是怎样产生的？荚语为什么成为国际语言？人们以不同的方式写着英语、说着英语。英语是世界上词汇最多的一种语言。英语是多种语言交汇而成的语言。在过去的１０００年当中，英语融汇了上至古代拉丁语、希腊语，下至法语、德语和意大利语在内的多种语言。英语里面甚至还有来自汉语和日语的词汇，总之，英语一直在不断地变化着，它的词汇一直在增加。     

A rational approach to career change

Recently, the number of physicians who have been interested in alternative careers has vastly increased. Many physicians express dissatisfaction with clinical practice, but they are uncertain about which nonclinical options are appropriate for them. Pursuing a different career after many years of studying and practicing medicine can seem like an overwhelming task. In this article, the author briefly outlines a decision-making process that can be used in analyzing career options and suggests some careers that have provided challenging opportunities for physicians.     

私有化对电信服务商技术能力提高的影响

提出一个技术能力的评估框架,即4种与主要增值活动相关的技术能力(创新能力、设计与工程技术能力、市场营销与销售能力、服务能力)和4种与辅助增值活动相关的技术能力(获取资源能力、人力资源开发能力、战略计划能力、信息技术能力),并将其应用于斯里兰卡电信公司私有化前后的考察,得出私有化带来了技术能力显著提高的结论.

A comprehensive literature review of the pelvis and the lower extremity FE human models under quasi-static conditions

Finite Element Modeling (FEM) has become a vital tool in the automotive design and development processes. FEM of the human body is a technique capable of estimating parameters that are difficult to measure in experimental studies with the human body segments being modeled as complex and dynamic entities. Several studies have been dedicated to attain close-to-real FEMs of the human body (Pankoke and Siefert 2007; Amann, Huschenbeth et al. 2009; ESI 2010). The aim of this paper is to identify and appraise the state-of-the art models of the human body which incorporate detailed pelvis and/or lower extremity models. Six databases and search engines were used to obtain literature, and the search was limited to studies published in English since 2000. The initial search results identified 636 pelvis-related papers, 834 buttocks-related papers, 505 thigh-related papers, 927 femur-related papers, 2039 knee-related papers, 655 shank-related papers, 292 tibia-related papers, 110 fibula-related papers, 644 ankle-related papers, and 5660 foot-related papers. A refined search returned 100 pelvis-related papers, 45 buttocks-related papers, 65 thigh-related papers, 162 femur-related papers, 195 knee-related papers, 37 shank-related papers, 80 tibia-related papers, 30 fibula-related papers and 102 ankle-related papers and 246 foot-related papers. The refined literature list was further restricted by appraisal against a modified LOW appraisal criteria. Studies with unclear methodologies, with a focus on populations with pathology or with sport related dynamic motion modeling were excluded. The final literature list included fifteen models and each was assessed against the percentile the model represents, the gender the model was based on, the human body segment/segments included in the model, the sample size used to develop the model, the source of geometric/anthropometric values used to develop the model, the posture the model represents and the finite element solver used for the model. The results of this literature review provide indication of bias in the available models towards 50th percentile male modeling with a notable concentration on the pelvis, femur and buttocks segments.     

细胞培养-Taqman PCR分析法——评估小隐孢子虫消毒

小隐孢子虫(Cryptosporidium parvum)污染是对水工程的一个挑战也威胁到公众健康。在此项研究中,我们开发了一种细胞培养-定量PCR分析法来评估消毒后小隐孢子虫的活性。我们用这种方法对水工程中多种消毒法包括低压紫外光(LP-UV),臭氧,混合氧化剂(MIOX),氯气进行评估。证实该检测方法是可信和敏感的,最低能检测到一个感染卵囊。有效的卵囊消毒(灭活率>2 log10 units)是采用LP-UV(20 mJ/cm2)或2 mg臭氧/公升(10分钟)。MIOX和氯气消毒卵囊效果最差(灭活率<0.1 log10 unit)。这些结果证实了MIOX对小隐孢子虫消毒的无效性。该检测方法是对饮用水和循环水消毒系统有效的评估方法。
