摘要： 利用双亲分离群体数量性状表型值可鉴定其主基因+多基因混合遗传模型,为数量性状遗传基础和作物育种提供参考信息。为全面总结数量性状分离分析的研究成果、添加软件包新功能和矫正以前版本的缺陷,在RStudio-1.4.1103平台和R编程语言框架下,开发了具有交互式图形用户界面的R软件包SEA v2.0。该软件可分析14种双亲分离群体类型,每种群体类型均有数据导入、数据分析、后验概率计算和分布曲线绘制4个模块。为节省计算时间,用doParallel包并行计算、data.table包读写数据和MASS包估计分布参数。用KScorrect、kolmim和shiny包简化程序。只要用户上传*.csv格式数据文件并设置相关参数,可快速显示计算结果。通过大豆结荚习性数据分析和MonteCarlo模拟研究,证实了SEAv2.0软件包的有效性。软件包可从https://cran.r-project.org/web/packages/SEA/index.html下载。

摘要： Any seafarer or mariner that uses the sea knows that navigation without correct charts is impossible and hazardous because nautical charts are the most essential and indispensable tools for vessels to sail safely at sea.For vessels to safely sail at sea,the seas and the oceans ought to be charted and this falls within the domain of hydrography.However,the seas cannot be charted effectively in the absence of the deployment of human resources and adequate tools like satellite and aerial imagery,survey boats and other equipment that will facilitate the hydrographic operations.The acquisition of data and information about the sea depths,nature of sea bed,waterways,navigational hazards and navigational objects among others,basically falls within the sphere of hydrography which is primarily known as survey at sea.The paper offers a review of geospatial technologies in hydrographic practice for enhanced safety of navigation at sea.The review is important to both the mariners,shipping industry and the government in order to explore the potentials provided by Geographic Information System,Remote Sensing,cloud GIS,big data GIS and Global Positioning System to enhance the practice of hydrography.The data and materials used for the review were obtained from literature in the internet and other published works.The paper looked at hydrography as a profession,roles of geospatial technologies in hydrographic practice,benefits of hydrography to national development and finally,the weaknesses of geospatial technologies in hydrographic practice were equally examined.

摘要： Unlike traditional transportation,container transportation is a relatively new logistics transportation mode.Shipping containers lost at sea have raised safety concerns.In this study,finite element analysis of containers subjected to hydrostatic pressure,using commercial software ANSYS APDL was performed.A computer model that can reasonably predict the state of an ISO cargo shipping container was developed.The von Mises stress distribution of the container was determined and the yield strength was adopted as the failure criterion.Numerical investigations showed that the conventional ship container cannot withstand hydrostatic pressure in deep water conditions.A strengthened container option was considered for the container to retain its structural integrity in water conditions.

摘要： 英国皮革协会负责人克里(Kerry Senior)呼吁其成员企业应当积极回应欧盟社会经济分析委员会(SEAC)制定的皮革六价铬的规定。克里称:"欧盟社会经济分析委员会(SEAC)已就拟议的皮肤敏感剂规定发表意见草案,并注意到其咨询机构的回应。好消息是,草案建议维持皮革六价中Cr含量为3mg/kg的上限,因为目前还无法准确地测量出低于3mg/kg的含量。"

摘要： An increasing number of countries of Central and Eastern Europe (CEE) have established some form of provision for strategic environmental assessment (SEA). Adoption and development in the region has been noteworthy and several countries have established legal frameworks that are relatively progressive. Some countries, notably the Czech Republic, Slovakia and Poland, also have a record of SEA practice. Their experience, particularly at policy level, is impressive even when judged by international standards and includes a number of aspects and lessons for SEA practitioners in other countries. Within CEE, this information has been shared already through regional exchanges, which themselves represent an interesting innovation in SEA capacity building and networking.

摘要： Hong Kong's roads have one of the highest vehicle densities in the world and its railways are among the most intensively utilized in the world. Associated with the existing and growing ransportation network are environmental pollution issues that require tackling at bothstrategic and local project level. Over recent decades, a series of Comprehensive Transport Studies and Railway Development Studies have formed the key blueprints for transport development in Hong Kong. This paper escribes the life-cycle of transportation projects in Hong Kong and presents how environmental inputs play a key role in the process, from Strategic Environmental Assessment (SEA) for territorial wide transport studies, through to project Environmental Impact Assessments (EIA), to Environmental Monitoring and Audit programs during project implementation. All these inputs aim to achieve a more sustainable transportation system.
