High-extensible scene graph framework based on component techniques

INTRODUCTION With the tremendous growth of the digital en- tertainment industry in the past decades, the scale of game scene is becoming more gigantic. To effectively manage and organize the massive data, game engine usually uses hierarchical scene graph. Many popular 3D modelling tools, such as Maya, 3D Studio Max, use scene graph to manage the scene content (Sowizral, 2000). 3D modelling software—Houdini directly edits scene graph to create and modify the virtual environment. Most v…     

浅谈我院图书馆阅览室的管理创新

论培养选拔党外干部对党的建设的促进作用

培养选拔党外干部是党的建设中的一项十分重要的工作。深入开展培养选拔党外干部工作，将促进我们党扩大执政的社会基础，促进我们党进一步健全自身体制和完善民主制度，促进我们党的干部队伍知识化、专业化建设，提高整体素质和整体水平，促进我们党进一步改进思想政治工作方法。     

高职院校人事分配制度改革的实践与研究

在高等教育大众化进程中，高职院校赢得了发展的新机遇，但高职院校现有的办学力量不强，师资结构不尽合理。因此，高职院校内部人事分配制度的改革已成为备受关注的实践性课题。在这改革中，把握形势、深入剖析、明确改革与发展的关系是前提。定编定岗、全员聘任、建立科学用人机制是关键，效率优先、兼顾公平、强化科学分配机制是核心。     

Application of derivative ratio spectrophotometry for determination of β-carotene and astaxanthin from Phaffia rhodozyma extract

INTRODUCTION Carotenoids are a class of natural fat-solublepigments generally found in plants, algae, and pho-tosynthetic bacteria, where they play a critical role inthe photosynthetic process. Carotenoids also exist insome non-photo-synthetic bacteria, yeasts, and moldswhere they may carry out a protective functionagainst damages by light and oxygen. Although ani-mals can not synthesize carotenoids within theirbodies, they can intake carotenoids from their dietsleading to bright meat col…

DNA: From Carrier of Genetic Information to Polymeric Materials

Research has shown that the DNA molecule can not only store genetic information but also serve as a polymeric biomolecule for the fabrication of functional materials. The unique precise molecular recognition capability and sequence programmability, combined with its good biocompatibility and biodegradability, impart the DNA molecule considerable potential for use in the construction of multifunctional materials. Depending on the composition, DNA-based materials have been generally categorized into pure DNA materials that are entirely composed of DNA and hybrid DNA materials that are composed of DNA and other functional compositions. Recently, we have developed a series of DNA-based materials that can be applied in diagnosis and therapy, and this review summarizes the relative work. Although challenges still exist regarding the real applications of DNA-based materials such as the high cost of DNA, the difficulty in scale-up, and the low resistance to nuclease, we believe that these drawbacks will be overcome with the development of technology, and new opportunities will emerge in the field of diagnosis and treatment.     

远程教学中"课堂搬家"两种技术实现方式的比较与分析

随着教育需求的不断增长，对学习资源特别是录制好的“课堂”电子类学习课件的需求也日益增加。近年，“网视宝”录制软件在课堂的现场录制、网上直播方面发挥着较大作用，提高了录制课堂、传播课堂的效率．有救解决了学习资源的供需矛盾；现在PowerPoint的联机广播功能也能够以一台计算机完成以前要靠网视宝、摄像机、计算机协同才能完成的任务，进一步降低了课堂录制、直播的成本，提高了效率，增加了课堂录制时间、地点上的灵活性，本文从经济性，操作性与技术性三个方面对这两种实现技术进行详细的比较与分析。     

浅淡思想政治教育对大学生科技创新的作用

当前科学技术发展日新月异,科技创新已成为国家发展与进步的重要基础。因此,高等教育必须培养大学生的科技创新能力,以利于他们面对今后竞争日益激烈的社会,高校要不断提高大学生的科技创新素质。高校的思想政治教育也可以推动大学生科技创新能力培养,可以培养高素质的社会主义建设者。所以,在培养大学生科技创新精神与创新能力的同时,我们要格外注重思想政治教育的促进作用。
