In this study, palm oil mill effluent (POME) was solubilized by batch thermo-alkaline pre-treatments. A three-factor central composite design (CCD) was applied to identify the optimum COD solubilization condition. The individual and interactive effects of three factors, temperature, NaOH concentration and reaction time, on solubilization of POME were(More)
Classification of wood images has always fascinated researchers and is a hot area of research as it brings automation in wood industry. Wood comes in different types and for a given wood; it can have some good part and some bad part like cracks, water affected and sapwood. The objective of this paper is to classify the sapwood region and the non-sapwood(More)
A series of previously unreported (2Z)-2-(1H-indol-1-yl)-3-(4-substituted phenyl)-1-phenylprop-2-en-1-one (5a–d) have been synthesized from easily accessible 2-(1H-indol-1-yl)-1-phenylethanone (3), which was obtained via a reaction of indole (1) with chloromethylphenyl ketone (2). The structures of the synthesized products have been elucidated using IR, 1H(More)
