The property of acidic sites onMoO3-ZrO2 was studied for n-heptane isomerization.A2,6-lutidine IRstudy showed that the introduction of MoO3 on ZrO2 partially eliminated the absorbance band at 1605 cm−1 ascribed to Lewis acid sites corresponding to the presence of the monoclinic phase of ZrO2 and developed several Brönsted and Lewis acid sites wi

Media components such as wheat flour, MgSO4 and particle size were screened by Placket Burman design (PBD) while the operating range was fixed by one-factor-at-a-time method (OFAT), primarily for the enrichment of cassava peels as animal feed. Optimization of the selected media components was carried out using Face–Centered Central Composite Desi

The possible biotechnological application of ligninolytic enzyme in a range of different fields has stimulated isolation and screening of potential microorganisms from local sources. Twelve white rot fungi (WRF) were isolated from around Gombak area (Malaysia) and sub cultured few times in order to obtain pure cultures. These strains were first scr

The upgrading of cassava peel into a nutritionally enriched animal feed by the white rot fungus Panus tigrinus M609RQY was investigated. Positive contributing media components were determined by Plackett- Burman design (PBD) and optimized by one-factor-at-a-time (OFAT) method. In the screening of media constituents, protein and lignin content were

Based on an inexpensive popular precision timing chip 555 timer, a resistance to time converter is proposed in this paper it is indeed capable of converting resistive and capacitive changes into pulse widths of proportional durations. This converter exhibits a compatibility of wider conversion range with a reasonable level of sensitivity required f

Artificial seagrass plays an important role for the distribution of benthic organisms and fishes. Based on this perspective a study was conducted in the Sepanggar Bay located in the Northern part of Kota Kinabalu, Malaysia from November 2006 to February 2007 to determine the potentiality of artificial seagrass as an alternative habitat for marine f

In this work, it was shown by calculations that crude-oil’s extinction is definite, and oil air-pollution is increasing significantly as a function of time (civilization). Hence, a parabloidal reflector antenna is suggested here to extract solar energy as a concentrated solar-induced heat. This heat could be used for industry, electricity generat

Mammalian cell lines, in particular CHO-K1 is vital for the multibillion dollar biotechnology industry. The majority of large scale bioprocessing of commercially aluable protein biopharmaceuticals is produced using this type of cell. An ideal mammalian cell system as host for biologics production should retain efficient use of energy sources in ord

Present study was conducted to determine the propagation and biodiversity of corals on artificial reefs at Teluk Kalong and Pasir Akar, Malaysia to check the feasibility of artificial reef to rehabilitate natural reef ecosystems and to provide artificial habitat for marine organisms. Two types of artificial reef deployed in these areas were Dome Re

Micro-electro discharge machining (micro-EDM) technique, an advanced noncontact machining process, is used for structuring of nonconductive ZrO2 ceramic. In this study copper foil as a conductive layer is adhered on the workpiece surface to initiate the sparks and kerosene is used as dielectric for creation of continuous conductive pyrolytic carbon
