A detailed description of the vaporization of an isolated droplet has been carried out in this experimental study aimed at investigating ethanol and another aliphatic alcohol, 1-propanol. The characterization of the vaporization phenomenon is necessary for this liquid fuel to develop efficient design of injection systems for propulsion and power ge

The use of green materials is a vital component in tackling problems of environmental protection. At the same time, these materials help solve problems arising from the shortage and undegradable nature of petroleum-based materials. Among the numerous green material sources in Malaysia, the sugar palm tree is a versatile plant that can produce biofi

A novel biocomposite where both natural fibre and matrix are derived from underutilized parts of sugar palm tree was successfully developed. This 100% green materials can lead to solve depletion and non degradable polymer waste disposal problems. Unfortunately, since moisture absorption is a matter of concern in biocomposites, the effect of water a

The motivation of this research is to develop a new biopolymer derived from sugar palm tree (Arenga pinnata) which can lead to solve non degradable polymer waste disposal problems. Therefore, this paper presents the development of alternative biodegradable material developed by using locally available sugar palm starch (SPS) in presence of biodegra

This paper is written in the framework of the Author's previous papers. The dynamics of quadratic stochastic Volterra operators (in short Volterra QSO) was deeply studied. However, we can still observe some chaotic behaviors of such operators. In this paper, we provide a criterion for an existence of the Li-Yorke chaos in a class of Volterra QS

Transient evoked otoacoustic emissions (TEOAE) is one of the useful objective tests to measure the integrity of outer hair cells and has been widely used clinically. Despite its successful, the TEOAE has several limitations and one of the problems that will be addressed in this study is the interaction of test time and highly background noise to th

Transportation plays an important role in achieving sustainable development. However, it has been regarded as one of the most arguable but least implemented concept in urban and transportation planning. The increasing dependence on private vehicles for various trip purposes has indeed put enormous pressure on the capacity of the road infrastructure

Jamiyah Singapore is a non-profit organization that aims to provide service to humanity by promoting missionary, education and welfare. Jamiyah Education Centre (JEC) is one of the organization’s pioneering project since 1970s. JEC provides Islamic education to all Muslims in Singapore ranging from pre-schoolers to adults. This study investigated

The sintering behavior of three different types of hydroxyapatite (HA) i.e. a commercial powder, HA(C), a synthesized powder by wet chemical precipitation method, HA(W) and a synthesized powder by mechanochemical method, HA(M) were investigated over the temperature range of 1000–1350 °C. It has been revealed that the sinterability and mechanical
