One of the biggest problems faced by the oil and gas industries is transmitting gas when there is a damaged pipeline. This damage may be a result from corrosion, crack or a burst pipe. Damaged pipelines need a safe, quick and efficient repair mechanism to prevent any further extensive damage. There are various methods and repair systems that offer

Silicon nitride is in the group of hard covalent materials (Homlberg and Matthews, 1994) and often has amorphous structures with the atomic bonding which are formed with very high cohesive forces (Grzesik, 2008) that can withstand high temperatures, higher resistance to abrasive wear and improved oxidation and chemical resistance (Kalpakjian, 2013)

Conveyor belts are used widely to carry and transport various materials ranging from fertilizers to foods items from the cargo ship to the packaging site. Spillage and carryback problems are common issues relating to transportaion of these types of materials at Malaysian ports. This leads to lots of wastage in fertilizers and food. In addition, ext

Electron state transition of deep level point defects in a semiconductor crystal was studied. Low-temperature grown GaAs produced excess antisite As (AsGa) which produces localized spin when doped with Be. A nearly abrupt decrease of 1.7% of the resistance is detected at a temperature around 4 K which is consistent with abrupt decrease of magnetiza

It is important to find new ways that are effective for the treatment of infectious diseases caused by drug-resistant bacteria such as the usage of plant extracts which have the antibacterial activity together with antibiotics which do provide synergistic effect. The objectives of this study are to evaluate synergism between different types of prop

α-Mangostin is a major compound found in mangosteen fruit hull and it has been reported to have wide range of pharmacological activities. The current study seeks to evaluate the in vitro activities of α-mangostin on adipocyte differentiation, glucose uptake and related gene expressions. The inhibitory effect of the compound on lipid accumulation

Abstract This review highlights the use of bromelain in various applications with up-to-date literature on the purification of bromelain from pineapple fruit and waste such as peel, core, crown, and leaves. Bromelain, a cysteine protease, has been exploited commercially inmany applications in the food, beverage, tenderization, cosmetic, pharmaceuti

In this paper, we investigate various theoretical frameworks of third sector (voluntary sector) economy with an aim to propose for a sustainable and inclusive socio-economic development model. An economic model that incorporates the third sector, together with the public and private sectors, is argued to be not only economically viable, but ethical

Being in the tropical region, Malaysia experience relatively high air temperature and humidity throughout the year. People are trying to avoid the sun. Improper landscape design could contribute further in the increasing outdoor air temperature. This would further affect the indoor microclimate. Nowadays people are turning to the mechanical solutio

The objective of this paper to present cytotoxic effect of jacalin, a purified protein and crude protein from A.heterophyllus seed against cancer cell, human breast cancer (MCF7) and non-small lung carcinoma (H1299). The extraction and purification were carried out by phosphate buffer precipitation and reverse miceller, respectively. MTT and trypan
