Objective: To test the effects of dietary mannan oligosaccharides (MOS) on clownfish Amphiprion ocellaris (A. ocellaris). Methods: Six levels (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 g/kg diet) of MOS were added to the basal diet (used as control diet) and fed clownfish A. ocellaris [total length (24.21 ± 0.16) mm] for 70 days. Growth performance and tissue protein were measured. Results: The result showed that growth rate was enhanced significantly in fish fed 0.10% and 0.15% MOS in diets compared to fish fed other MOS levels or control (P < 0.05). Survival rate significantly increased in fish fed diets with 0.20% and 0.25% MOS, compared to control. Fraction rates of protein growth were significantly higher in fish fed diets with 0.15%, 0.20%and 0.25% MOS supplementation than those fish fed other MOS inclusion levels and the control (P < 0.04). Dietary MOS concentrations and clownfish growth rates were significantly correlated. Optimal MOS concentration was predicted to be 0.185%, 0.173% and 0.171% at Days 14, 42 and 70, respectively. Conclusions: In conclusion, MOS-supplemented diet benefits for boosting growth, survival and body composition of the clownfish, A. ocellaris.

越南革新开放以来,国家走上了外向型的经济战略发展道路,在借鉴社会主义发展中国家发展的经验基础上大力发展本国的经济,采取了一系列的措施以推进越南经济的发展。越南正在积极建设和完善法律体系,从而逐步适应国际惯例。因此,在全球经济一体化进程中不断改善投资环境,完善相关法律,积极发掘经济增长潜力,推动经济多元化发展,增强经济政策的开放度和透明度,是保持越南社会经济可持续发展的重要保障。在外国对越投资方面,诸多中国企业对越南进行了投资,从投资规模上.来自中国企业的投资进入了越南外来投资排行榜的前十名,但从中国投资越南的现状来看,中国投资越南多是质量一般,规模不大,这与中国的国际地位以及经济发展规模不相匹配。为发掘中国对越南投资的潜力,加大越南对外招商引资的力度,需要中越两国探索新的路径。中国企业到越南投资过程中的投资风险不可忽视,尤其是跨境投资,面临的风险更加复杂。越南建设规模迅速扩张,中国企业对越投资项目面临着来自不断增加的东盟和其他国家投资的竞争,无论是对越南还是包括中国在内的其他国家,构筑有效的投资风险防范体系都具有迫切性。本论文全文共分五个部分,第一部分是对本文的研究的一些研究现状和理论的概述,第二部分分析了国际投资的发展现状与问题,从行业分布、区位选择等几个方面加以分析,分析了越南利用外资存在的问题,包括:资金支付率、投资回报率低、技术转移效率不高、投资区域不平衡等诸多方面。第三部分是定性地分析中国大陆投资对越南经济发展影响,从资本贡献,技术贡献以及对经济发展的产业结构调整等正负影响两个方面来说明;第四部分是定量地分析中国投资对越南经济发展影响,分别从中国投资与越南经济增长的关系及与产业结构的关系两个方面来分析,最后一部分是在前文分析的基础上,得出研究结论并提出相关建议。

目的：对单独补充维生素D与结合补充维生素D和钙与安慰剂和钙剂对比预防中老年骨质疏松性骨折的疗效进行系统评价。方法：计算机检索Cochrane协作网数据库(1992-2014年12月份),MEDLINE(1992-2014年12月份),EMBASE(1992-2014年12月份)、中国生物医学文献数据库(CBM,1992-2014年12月份)、中文期刊全文数据库(CNKI,1992-2014年12月份)。手工检索国内期刊已发表的论文和会议资料,收集所有相关随机对照试验,并评价纳入研究的方法学质量。统计软件使用Cochrane协作网提供的RevMan5.3结果：计算机检索到相关文献81篇,最终纳入24个随机对照试验(RCT),包括141047例患者。Meta分析结果：1、关于死亡率治疗组与对照组对比的死亡率无统计学意义,其中维生素D结合钙组与对照组分析结果：RR=1.24(95%CI=0.91-1.70,P=0.18);维生素D组与对照组分析结果：RR=1.05(95%CI=0.97-1.13,P=0.27);2、关于骨折发生率单纯维生素D组与对照组的发生率无明显优势：RR=0.97(95%CI=0.89-1.04,P=0.38);维生素D结合钙组与对照组的发生率有统计学差异：RR=0.90(95%CI=0.82-0.98,P=0.02);3、关于血清25羟基维生素D浓度治疗组的血清25羟基维生素D浓度明显比对照组提高。结论：单独补充维生素D和结合维生素D和钙与对照组对比的死亡率没有区别;血清25羟基维生素D浓度通过治疗虽然改善但还没达到骨健康状态;单独补充维生素D预防骨质疏松性骨折无明显优势;维生素D结合钙可降低骨质疏松性骨折的发生率。

Sustainable construction in the future will be influenced significantly by the beliefs and actions of civil engineering students studying at university today. A comparative investigation of the appreciation and attitudes regarding sustainable construction of civil engineering students at The NUCE （National University of Civil Engineering） in Vietnam, and the Universities of Loughborough and Liverpool in the UK were therefore conducted. Results indicate that students at all three universities appreciate the importance of the development of sustainable construction and have positive attitudes with regards to sustainability. Construction design and appropriate use of materials were two issues generally considered the most important with regards to sustainability, but were also thought to be adequately covered on the courses in all three institutions.

本文是基于考古发掘获取的人骨遗存在内的89组古代及现代的人群样本而做的颅骨形态测量研究,侧重说明解剖学意义上的现代人(anatomically modern humans)在欧亚大陆东部演化分布的“二层”模式。距今6.5万~5万年以前,“第一层”现代人经东南亚大陆向东、向南扩散,他们与现今安达曼人、澳大利亚人、巴布亚人的祖先以及日本绳纹时代人群最为接近。距今约九千年前,拥有东北亚血统的“第二层”现代人出现在中国中部地区,并于距今四千年前后向南扩张至东南亚地区,这些人群在颅骨形态上与西伯利亚人具有密切的亲缘关系。上述两大人群最初交流有限,在农业能够支撑增加人口密度的情境下,“第二层”现代人增长速度较快,人口数量较多。这两层人群显著的二重结构特征,表明了现代人在欧亚大陆南、北不同迁移路线间的历时性差异。
