Global concerns on quality and environmentally sustainable products are giving extensive pressure on the competitiveness of Malaysian palm oil industry. As part of palm oil supply chain, the fresh fruit bunch (FFB) dealers play an important role in the development of the industry a...
Investigating the Possibility to Reduce the Residual Stress Level in 2.5D Cutting Using Titanium Coated Carbide Ball End Mill
End milling is a multipoint cutting process in which material is removed from a workpiece by a rotating tool. It is widely used in cutting 2.5D profiles such as point-to-point, contouring, and pocketing operations. 2.5D machining possesses the capability to translate in all 3 ...
Effect of Phosphoric Acid Concentration on the Optical Properties of Partially Phosphorylated PVA Complexes
Partially phosphorylated polyvinyl alcohol (PPVA) films were prepared at five mole ratios of phosphoric acid (PA) using solution casting technique. The optical properties of the PPVA films were examined using UV-visible (UV) and photoluminescence (PL) spectroscopy. The UV absorption spectra revea...
Are virtues national, supranational, or universal?
Many studies investigated cultural differences in values, most notably by Hofstede and Schwarz. Relatively few have focused on virtues, a related and important concept in contemporary social science. The present paper examines the similarities and differences between nations, or blocks of -&...
