Ruby:一个基于移动设备的个人信息管理系统

为满足移动环境对非结构化个人信息管理的自然性和高效性的需求,提出一个基于移动设备的个人信息管理系统Ruby.首先分析了移动环境对个人信息管理的需求,描述了系统框架,接着介绍了系统界面和交互过程,并阐述了支持该系统的2个主要技术:非结构化笔记编辑技术和基于笔迹标签的检索技术.对2个技术和整个系统的评估结果表明,该系统能够满足移动环境对自然交互、非结构化信息采集加工及个人信息自然检索的需求.

Purification and characterization of L-amino acid oxidase from Agkistrodon blomhoffii ussurensis snake venom of Changbai Mountains

The L-a. a, oxidase of Agkistrodon blomhof fii ussurensis of Changbai Mountains in northeast of China has been separated by using ion-exchange and gel filtration techniques, This enzyme is composed of two subunits, the molecular weight of one subunit is about 36 000, the another is about 57 000, determined by sodium dodecyl sulfate-polyacryamide gel electrophoresis and matrix assisted laser desorption ion/time of flight mass spectrometry, The activity of L-a, a. oxidase determined using L-Leu as substrate. The optimal pH of the enzyme is 4. 5 similar to 5. 5 and 8 similar to 9. The UV-Visible absorption spectrum of L-a, a. oxidase shows the characteristics of flavor-proteins.
