Teaching and learning in microsystems engineering

Whereas research in MicroSystems Technology (MST) has grown rapidly over the last twenty years, the education of engineers at postgraduate level is still in its infancy. The number of dedicated MST research institutions, companies and university laboratories worldwide has grown at a dramatic rate and all require trained individuals who can be immediately operational in the workplace. With the possible exceptions of Germany and Switzerland, the authors of this article believe that the training requirements for such scientists, engineers and technicians have not been satisfactorily addressed as yet. Realising the need for adequate training in MST, the British funding agency for research in science and engineering, the EPSRC (Engineering and Physical Sciences Research Council) awarded a substantial grant to Heriot-Watt University in order to set up a Masters Training Package (MTP). The context of this grant, the syllabus developed for this Master of Science as well as its implementation are presented in this article. Advantages and drawbacks of block-based delivery of the course are presented from a pedagogical point of view for the different categories of students (full-time students, part-time students and company delegates).

A methodology for the identification of glass panes of different origin in a single stained glass window: Application on two 13th century windows

The chemical composition of 11 glass panes originating from two 13th century non-figurative windows were analyzed by means of Scanning Electron Microscopy–Energy Dispersive X-ray system (SEM-EDX). The windows were discovered in the back-wall of the triforium during the restoration of the choir of the cathedral St. Michael and St. Gudule in Brussels (Belgium). In order to determine if these windows were fabricated with glass of different origin or not, the compositional difference between the panes were compared with the variation in composition as a result of the following causes: (1) compositional fluctuation between panes cut from the same sheet of glass, (2) compositional fluctuation caused when panes are cut from different sheets that were made with the same batch, (3) compositional fluctuation caused when the glass is made from different batches at the same production center, and (4) compositional fluctuation as a result of glass produced at different fabrication centers.     

温控炭焙对武夷岩茶生化品质的影响

温控炭焙结合传统炭焙的优点,并结合现代温度控制技术,对于保持茶叶品质的稳定和高效利用能源具有重要作用。采用武夷岩茶为材料,在130℃、120℃和110℃温度下分别烘焙6h,分析不同炭焙温度对武夷岩茶水仙感官品质、主要理化成分的影响。结果表明：以温控炭焙130℃6h处理的茶样感官审评得分最高。氨基酸、茶多酚、咖啡碱含量呈下降趋势,水浸出物含量差异不显著。汤色RGB值CK处理最大,A3处理最小。
