SHARPENING TOOTHED CUTTING TOOLS DESIGN

Molecular Informatics: Sharpening Drug Design’s Cutting Edge

The word ‘drug’, which derives from the Middle English word ‘drogge’, first appears in the English language during the 14th century and it has, at least during the last century, become, arguably, one of the most used, and misused, of words, becoming tainted by connotations of misuse and abuse. The dictionary definition of a drug is: ‘a substance used medicinally or in the preparation of a medic...

Sharpening Skills in Using Presentation Tools: Students' Experiences

Making use of Information and Communication Technology resources is deemed necessary for students. With this, they need to demonstrate their competence in using various technologies such as Prezi and PowerPoint to communicate effectively and efficiently. Hence, their experiences in using these presentation tools is important to assist them in their needs. In this study, all the fourth year Bach...

Comparison of Cutting Ceramics with Hard Metal Cutting Tools

Cutting ceramic tools are used especially at high cutting speeds in the machining process. The highly brittle type of structure and the tendency for cleavage (crack formation) are the infavorable properties of these materials, which keep their hardness at high temperatures. The hard metals are produced by sintering of the carbides such as whisker WC, TiC and TaC with the presence of Co as a bin...

Innovative Design and Performance Evaluation of Bionic Imprinting Toothed Wheel

A highly efficient soil-burrowing dung beetle possesses an intricate outer contour curve on its foreleg end-tooth. This study was carried out based on evidence that this special outer contour curve has the potential of reducing soil penetration resistance and could enhance soil-burrowing efficiency. A toothed wheel is a typical agricultural implement for soil imprinting, to increase its working...
