基于iRODS的分布式文件管理共享系统GDOCUment

随着科学数据库中的资源迅速增加,对这些资源的共享使用和管理提出了新的要求。iRODS(i RuleOriented Data Systems)是美国圣地亚哥超算中心(SDSC)开发的一个数据网格中间件及其相关的工具系统,介绍了iRODS的体系结构和主要特点,并基于iRODS设计开发了一个分布式文件管理与共享系统GDocument,它能有效管理分布式异构数据,并提供统一的访问和集成共享。

Morphological and Phylogenetic Studies of a Copepod Species, Irodes parupenei Ho and Lin (2007), Infecting Parupeneus rubescens in Saudi Arabia

Dammam City is one of the gorgeous coastal areas in the Arabian Gulf of Saudi Arabia.The present study aimed to ex-amine one of the copepod species infecting the rosy goatfish that represents a highly consumed fish species by the local population in the Arabian Gulf.The copepod species isolated from the infected fish specimens belong to the family Taeniacanthidae and was iden-tified as Irodes parupenei Ho and Lin(2007),primarily based on its morphological,morphometric,and ultrastructural characteris-tics,especially the structures of the dorsal cephalic area,segmentation of the first antenna,the absence of the maxilliped claw in the fe-male specimens,and the setation and spinulation of the legs 2-4 for the adult females are of great significance in the taxonomic iden-tification.The 18S rRNA gene sequence was analyzed to ensure the precise identity and exact taxonomic status of the copepod species.The result showed that this copepod species belong to Taenicanthidae and closely related to Irodes sauridi(gb|JF781550.1)in the same taxon.More details on the specificity of the goatfish for Irodes species and identifying these parasitic taxa using molecular analysis are given in the present study.

iPod nano 3rd

史上最受欢迎的MP3随身听，也是最为成功的iRod——nano，我们终于等到了它的第三代升级版。这款nano以一副酷似“小胖”的可爱模样出现，苹果加强了它的视频播放能力，2英寸的显示屏虽不算大，但锐利度与对比度仍是令人非常满意。与Classic一样，它也加入了苹果最新的CoverFlow浏览界面，这个被史蒂夫乔布斯（Steve Jobs）称为最佳的界面相信不会让人失望。
