This research study measures the support for learners through the use of a Virtual Learning Environment project website. The website prepares, assists and supports the learners through their Mechanical Engineering Projects in an accredited academic programme. The research question answered was "Is the VLE website helpful to learners in the final years of mechanical engineering projects?" The research focuses on the learners' experiences of using the project website and explores their views regarding the website. The literature relating to the study indicates that similar programmes have had positive results in relation to the adoption of VLEs to support *** data collection process involved an initial questionnaire about the website for the quantitative analysis. Thirty-nine project learners from the third and fourth years of the Mechanical Engineering programme participated in the questionnaires. The analysis of the questionnaire results indicated that the project website VLE was very helpful to learners completing their Mechanical Engineering projects. They all used the website for different aspects of the project but they still wanted a lecturer or lecturers to consult with for problems during the course of the project. The kinesthetic learning achieved in the project modules cannot be replicated or replaced by any virtual learning environment. The website afforded the learner to be better prepared for the project start in September. It gives the learner another resource to refer to when they were working at home, during the holidays or when they come to a particular part of the project. The website also teaches the learner to use the internet, videos, screencasts, tutorials, etc. to help them to complete the *** website has enhanced student learning, motivation, earlier starts to project, peer learning and has improved the quality of projects.

Forty-eight interviews were undertaken with residents in Timaru, Wanganui and Napier, New Zealand, in 2008 to explore how people understand and use information about earthquake hazards and preparedness, and how this process affects actual preparedness. Three main types of information were identified as being utilized by people： passive information （e.g., newspapers, brochures, TV, radio, websites）, interactive information （e.g., community activities, school activities~ and workplace activities）, and experiential information （e.g., experiencing a hazardous event, responding to an event, and working in an organization that deals with hazards）. People tended to either contextualize hazard and preparedness information around any prevailing beliefs they had or form new beliefs on exposure to information. A number of core beliefs were identified as crucial for helping people consider that preparing is important and motivating actual adjustment adoption. Society also has an influence on how people interpret information and form intentions to prepare. People are often influenced by the opinions of others, and as preparing for disasters is not seen as a societal norm, this can cause people not to prepare. Feeling a responsibility for others （e.g., children） appears to be a major driver of preparedness. Other societal factors such as trust, leadership and sense of community also influence interpretation, dissemination and use of hazards and preparedness information. Finally, a number of resource issues can help or hinder preparedness.

为了降低Ⅲ族氮化物材料和器件的成本 ,必须开发大尺寸的Ⅲ族氮化物MOVPE生长的反应器。本文报道了EMCORE公司的一种带有旋转盘的立式反应器 ,其中的衬底片载盘直径为 32 5mm。每次沉积过程中 ,载盘上可以放置 2 1片 2英寸直径的衬底片。反应器的内壁通过水冷 ,其温度可保持在 5 0～ 6 0℃之间。衬底片可用电热丝加热 ,沉积中衬底载盘的旋转速度可达 1 0 0 0～ 1 5 0 0rpm。本文给出了用这种 32 5mmGaN生长系统生长的未掺杂GaN ,InGaN和 p GaN外延层的相关结果。这些结果表明 ,这种旋转盘的反应器是一种很适合大尺寸载盘的系统 ,完全满足Ⅲ族氮化物材料体系生长的要求。与在小反应器中生长的材料相比 ,用这种大反应器生长的材料具有相同的质量。这种 32 5mm的GaN反应器将使制备蓝光和绿光LED所用的Ⅲ族氮化外延材料的生产成本得到显著的降低。

We report here how a heterotopic penetrating peptic ulcer progressed to cause small bowel obstruction in a pa- tient with multiple previous negative investigations. The clinical presentation, radiographic features and patho- logical findings of this case are described, along with the salient lessons learnt. The added value of wireless cap- sule endoscopy （WCE） in such circumstances is debated.
