Graphite has attracted both academia and researchers due to its outstanding properties such as having strength 200 times stronger than steel, great efficiency of heat and electricity conduction, low cost and also facile fabrication. In this study, two facile approaches of producing nanosize graphite were performed; thermal expansion and sonication. Graphite that was produced are used as reinforcement in epoxy composite for adhesive applications. In order to determine the mechanical properties of the composite, tensile test was performed using Dumbbell shape of sample. The outcome of the test shows that 1 wt% of expanded graphite produce the highest value of Young Modulus which is 18 MPa. It was also found that adding more expanded graphite increased the ductility of composite by lowering epoxy brittleness. As for adhesive testing, double cantilever beam was used using Universal Testing Machine where the result shows that 1 wt% of expanded graphite demonstrates the highest value of adhesive toughness which is 9398 J/m2. The result of porosity-density indicates that porosity of composites will affect the mechanical properties. From the overall results, it is conclude that smaller weight percentage of expanded graphite produces better composite while for sonication process shows no difference at all. Thus demonstrates that time of dispersion does not give significant effect on the maximum load and stress of the composites.
Science, Technology, Engineering and Mathematics (STEM) subjects have always been complex subjects for school children as many experienced difficulty and complexity in grasping the basic conceptual knowledge. Therefore, Centre for Diploma Studies (CeDS) of Universiti Tun Hussein Onn Malaysia (UTHM) is moving forward to achieve sustainable development for society by pursuing Corporate Social Responsibility (CSR) through National Blue Ocean Strategy 4 (NBOS 4) initiatives. As a member of the society, CeDS try to ensure that the society will acquire the benefit of CeDS business activities as a whole.. ScienceXplorer programme had been implemented to attract primary school students in learning science. ScienceXplorer is a programme that basically implementing the concept of learning by doing. This study was performed to assess participant perception towards the implementation of ScienceXplorer. A self-completion questionnaire had been designed with a series of Likert scale questions that organized to gather participants’ perceptions of participating ScienceXplorer. The questionnaire had been designed using Kirk Patrick Evaluation Model. There were 148 participants from three primary schools took part in this study. In this scope of study, ScienceXplorer participants rated very high in terms of reflection, knowledge and skill, changes in behaviour and aspiration.
eXtreme Programming (XP) is one of new discipline of software development methodology on values of simplicity, communication, feedback and also courage. XP is an explorative and agile development method that seeks to satisfy the customer through early and continuous delivery of valuable software. XP software development process starts with planning, and all iterations consist of four basic phases in its life cycle: designing, coding, testing, and listening. This paper tends to report the experience in adapting XP in developing electronic document online system for the use of Centre for Diploma Studies, Universiti Tun Hussein Onn Malaysia (eDoc). The project under study is a system that is use to store office documents such as letter in an online database. The objective of this paper is to discuss the XP practices that had been choosed and also the lesson learnt by practising XP in developing eDoc.
Most people agreed that Google Maps set the standard for ease of use when it comes to a free online web mapping services. In addition, different map views are available which user can choose from the options of a terrain view, normal map view, or satellite image view based on their needs. Embedding a Google Maps on a website will not only make it more user-friendly but also enable people to access certain location with more ease. This paper intends to introduce the use of this geoinformatics services from Google along with Grails services in creating a simple interactive map for highway construction sites. A discussion will cover up the use of programming interface provided by Google and Grails (open source web application framework) and also the advantages of embedding the map to the website.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
