Lignin is an important constitute of the wood and thus the organism like fungi and insects growing on wood produce some extracellular lignolytic enzymes. In fungi these enzymes include different oxidases and peroxidases. Lignin peroxidases, manganese peroxidases, versatile peroxidases and laccases have been characterised from fungi and their roles

In the present research, cryogenic cooling was applied in refining the weld microstructure and the dimension. The investigation was conducted by producing weld melts on a 1.5 mm thick FSS plate using TIG torch with different energy inputs in a pure argon environment. A Box- Behnken experimental design was adopted with current, traversing speed and

Surface alloying with ceramic powder uses a high energy input to create composite coating that provides protection against wear and corrosion. In this work TiC incorporated composite coating was created by melting single tracks in 1.0 mg/mm2 TiC powder preplaced on alloy steel surfaces using a conventional TIG welding torch produced at 80 ampere cu

Surface cladding utilizes a high energy input to deposit a layer on substrate surfaces providing protection against wear and corrosion. In this work, TiC particulates were incorporated by melting single tracks in powder preplaced onto AISI 4340 low alloy steel surfaces using a Tungsten Inert Gas (TIG) torch with a range of processing conditions. Th

This paper discusses the uses of non-precious metals in catalytic converters to bring down the cost without sacrificing the performance capability. Copper powder and nickel catalyst were chosen as the alternative catalysts to reduce the use of precious group metals (PGMs) platinum, palladium, and rhodium. Simulation by COMSOL has shown that Nickel

This paper studies the effect of impact damage on carbon/epoxy laminates which have undergone hygrothermal ageing. Three stratifications have been chosen whereby the first layup is the classical type used in the industry and the other two are of quasi-isotropic/quasi-homogeneous properties consisting fibres orientated at ±45°and ±60°. The speci

The main objective of the study is to examine the extent Malaysian government-linked companies (GLCs) report on the environment. The government has strongly emphasised social and environmental responsibility amongst GLCs through the introduction of the 'Silver Book' and other "green" initiatives. Given this and the fact that GLCs ar

This article uses the Quranic philosophy of history, al-I‘tibar, in understanding what’s, why’s and how’s, which brought about the fall of the Umayyads. Based on this and the fact that history may, as Jeffrey Bartholet observes, “feed on itself,” the factors that caused the downfall of the Umayyads were on the one hand, explicatorily ev

Long Term Evolution-Advanced (LTE-A) is a new radio access technology that is expected to provide better experience among the mobile cellular users. It delivers multimedia services using packet switching technology. Therefore, intelligent design of packet scheduling for the LTE-A to provide Quality of Service (QoS) comparable to fixed line services
