Ethnomedical Survey of Aborigines Medicinal Plants in Gua Musang, Kelantan, Malaysia

The practice of herbal medicine had been diminishing, which may lead to the loss of valuable information about healing herbs. Therefore, an ethnomedical analysis was carried out in order to document the traditional medicinal uses of plants, which are commonly used among the Kelantanese Aborigines. A detailed systematic exploration of traditional ethnobotanical knowledge of medicinal plants of rural area in Kelantan was carried out mainly through interviews among aboriginal households (house-to-house interviews) and traditional healers. A total of 46 species was identified as having potential medicinal efficacy in curing different diseases and illnesses. Findings from this study can be used as a pharmacological basis in selecting plants for further phytochemical and pharmaceutical-nutrition studies

Design of a five-axis ultra-precision micro-milling machine—UltraMill. Part 1: Holistic design approach, design considerations and specifications

High-accuracy three-dimensional miniature components and microstructures are increasingly in demand in the sector of electro-optics, automotive, biotechnology, aerospace and information-technology industries. A rational approach to mechanical micro machining is to develop ultra-precision machines with small footprints. In part 1 of this two-part paper, the-state-of-the-art of ultra-precision machines with micro-machining capability is critically reviewed. The design considerations and specifications of a five-axis ultra-precision micro-milling machine—UltraMill—are discussed. Three prioritised design issues: motion accuracy, dynamic stiffness and thermal stability, formulate the holistic design approach for UltraMill. This approach has been applied to the development of key machine components and their integration so as to achieve high accuracy and nanometer surface finish
