Ice Jam modelling of the Lower Red River

Journal of Water Resource and Protection 2012年第1期4卷 1-11页

作者： Karl-erich Lindenschmidt maurice Sydor Rick Carson Robert Harrison 不详

The lower reach of the Red River between Winnipeg and Lake Winnipeg is very prone to ice jam flooding. The one- dimensional ice jam model RIVICE was implemented for this reach to better understand the processes leading to such events and to provide a tool to evaluate strategies for ice jam mitigation. The most downstream portion of this river stretch flows through a delta and marsh system which poses challenges in modelling ice jams in such an area of low-lying topography and river banks. Solutions to overcome these challenges are discussed in this paper and results of one such solution using water abstractions from the main channel are also presented. Abstractions are inserted in the model to represent under-ice leakage from the main channel to side channel storage and diversions (up to 65% in the Red River delta) and spillage into the delta floodplain.

为研究小型化、微型化天线在现代无线应用中的集成趋势,对当前工艺水平下的毫米波段片上天线(AoC)设计进行了总结。从集成角度,对单片集成和混合集成的概念分别进行了优劣比较和讨论。作为一个单片集成技术方案的可靠候选,对硅基单片毫米波集成电路(SImmWIC)技术进行了介绍,并给出了利用该技术实现的整流天线例子。通过单片集成的雪崩二极管发射机展示了如何利用三维电磁仿真工具设计及证明片上天线的性能,利用仿真和实际验证探讨了硅基毫米波片上天线的挑战和方法,为小型化雷达系统方案提供了一个稳固的基础。

Introduction mycotoxins are toxic secondary metabolites of various fungi, mainly those belonging to the genera Fusarium, Aspergillus and Penicillium. The major classes of mycotoxins in animal feed industry are aflatoxins, zearalenone, trichothecenes (e.g. deoxynivalenol,1-2 toxin, DAS), ochratoxin A, fumonisins and the ergot alkaloids. Their global occurrence is considered to be a major risk factor, as according to the Food and Agriculture Organization (FAO) as much as 25% of the world’s crops are affected annually despite increased efforts of prevention (Cortyl and Heidler, 2001).

Searching Clue of the Relationship between the Alteration of Bioactive Ingredients and the Herbal “Property” Transformation from Raw Rehmanniae Radix (<i>Sheng-Di-Huang</i>) to Steam-Heating-Processed Rehmanniae Radix (<i>Shu-Di-Huang</i>) by Chromatographic Fingerprint Analysis

“Di-Huang” (Rehmanniae Radix) is a peculiar Chinese herbal drug, the fresh root named “Xian-Di-Huang” (“Xian” means fresh;the commerce is now rarely available), mild-baking-dried raw roots “Sheng-Di-Huang” (“Sheng” means raw) and steam-processed “Shu-Di-Huang” (“Shu” implies steam-processed). The both kinds of herbal drug exert different efficiencies with different property according to the traditional clinical theory. It would be of interest that searching the clue of why the therapeutic functions of the same drug differ between the pre- and post-processing. To disclose the comprehensive alteration of the iridoids, saccharides and phenylethanoids occurred between the raw and steam-processed “Di-Huang”, the HPTLC and HPLC chromatographic fingerprint analysis has been carried out. The results showed that in the raw crude drug, the iridoids like catalpol is the major bioactive components, and the oligosaccharides composition kept rather consistent;however, in the steam-processed Di-Huang, iridoids was almost disappeared and the oligosaccharides were hydrolyzed gradually through the repeated steam-heating process. The worst case showed only fructose was detected with other minor residual components in the root tuber. It is due to presumably the uncontrollable steaming process in folk workshops. Defining reasonably the boundary between the “Sheng-Di-Huang” (mild-baking-dried Rehmanniae radix) and “Shu-Di-Huang” (steaming processed Rehmanniae radix) set up by chromatographic fingerprint pattern and standardizing the process would be necessary for assuring the consistent quality of the commercial herbal drugs.
