This paper presents an experimental program on rapid chloride permeability test on lightweight concrete produced from oil palm clinker aggregates. Oil palm clinker is obtained from by-product of palm oil milling. Utilising oil palm clinker in concrete production not only solves the problem of disposing this solid waste but also help to converse natural resources. The parameter of investigation ...

Abstract. Most plant-available Si in strongly desilicated soils is provided through litter decomposition and subsequent phytolith dissolution. The importance of silicon (Si) cycling tropical soil–plant systems raised the question whether oil-palm (Elaeis guineensis Jacq.) cultivation alters cycling. As oil palms are considered hyper-accumulators, we hypothesized that much stored above-ground bi...

Windmill palm (Trachycarpus fortunei) fibre was obtained from different parts of windmill-palm trunk sheath and then treated by sodium hydroxide solution and hydrogen peroxide to obtain the treated palm fibril. The appearance of raw windmill palm fibre and treated palm fibril, morphological characteristics, and statistical analysis of fibril length, diameter, and degree of hollowness were studi...

Biometrics is playing an important role for person recognition. The Biometrics identification of an individual is can be done by physiological or behavioral characteristics; where the palm print of an individual can be captured by using sensors and is one of among physiological characteristics of an individual. Palm print is a unique and reliable biometric characteristic with high usability. A ...

Expansion of oil palm plantations has led to extensive wildlife habitat conversion in Southeast Asia [1]. This expansion is driven by a global demand for palm oil for products ranging from foods to detergents [2], and more recently for biofuels [3]. The negative impacts of oil palm development on biodiversity [1, 4, 5], and on orangutans (Pongo spp.) in particular, have been well documented [6,...

The palm vein is one of the most reliable physiological characteristics that can be used to distinguish between individuals. Palm vein technology works by identifying the vein patterns in an individual's palm. The key techniques of palm vein recognition can systematically described in five parts extracting region of interest (ROI), preprocessing to image, extracting palm vein pattern, extractin...

Transesterification of palm olein with glycerol can increase the functionality by introducing additional hydroxyl groups to the triglyceride structure, an advantage compared to using palm olein directly as feedstock for producing palm-based polyol. The objective of this study was to synthesize transesterified palm olein-based polyol via a three-step reaction: (1) transesterification of palm ole...

Microsatellite markers containing simple sequence repeats (SSRs) are a valuable tool for genetic analysis. Our objective was to identify microsatellite markers that could be used to differentiate between male and female date palm (Phoenix dactylifera). The date palm is a dioecious plant whose sex cannot be determined until it reaches a reproductive age between 5 and 10 years. An early selection...
