Application of agriculture residue especially in biochar form seems to be effective in the removal of contaminants such as nitrate pollution. The effectiveness of biochar produced from palm leaf residues (pyrolyzed at 600 ˚C) in the removal of nitrate from aqueous solution was studied at different pH. The pH value at the point of zero charges (pHpzc) and surface functional groups...

Palm leaf manuscripts were one of the earliest forms of written media and were used in Southeast Asia to store early written knowledge about subjects such as medicine, Buddhist doctrine and astrology. Therefore, historical handwritten palm leaf manuscripts are important for people who like to learn about historical documents, because we can learn more experience from them. This paper presents a...

The objective of the study was to analyze chemical structure of date palm (Phoenix dactylifera L.) by employing ultimate, proximate and thermo-gravimetric techniques. Samples from different anatomical parts of date palm, namely trunk, frond base, frond midrib, leaflets, coir, fruit stem, date stone, and fruit empty bunches were considered for the experiments. Based on the findings in this work ...

The research objective was to produce activated carbon from palm-oil shells by one step pyrolysis and steam activation in a fixed bed reactor with the diameter of 100 mm. The studied variables were activation temperature, activation time, palm-oil shell sizes and flow rate of air. The results showed that the optimum condition was 1.18-2.36 mm of palm-oil shells at 750C for 2 hr with air flow ra...

Anthropogenic land-cover change is driving biodiversity loss worldwide. At the epicenter of this crisis lies Southeast Asia, where biodiversity-rich forests are being converted to oil-palm monocultures. As demand for palm oil increases, there is an urgent need to find strategies that maintain biodiversity in plantations. Previous studies found that retaining forest patches within plantations be...

The proportion of the leaf blade, leaf sheath and stem fractions in six rice straw varieties averaged 30, 40 and 30%, respectively. In vitro dry matter digestibility (IVD) of these fractions, estimated by the cellulase-neutral detergent solution procedure, was 503, 513 and 610 g/kg, respectively. The lower IVD of the blade and sheath was due to lower degradation parameters estimated by a simple...

Abstract—This work reports the potential of using Palm Kernel (PK) ash and shell as a partial substitute for Portland Cement (PC) and coarse aggregate in the development of mortar and concrete. PK ash and shell are agro-waste materials from palm oil mills, the disposal of PK ash and shell is an environmental problem of concern. The PK ash has pozzolanic properties that enables it as a partial r...

Tamil is one of the oldest languages in the world with rich literature. In the ancient days, the writers, especially in Tamilnadu, used palm leaves to encrypt their writing. A very good example of the usage of Palm leaf manuscripts to store the history is Tamil grammar book named Tolkappiyam which was written during 4th B.C. The ancient literature includes many palm leaf manuscripts that contai...

The relationships between foliar weight/leaf area and four stem dimensions (dbh, total stem cross-sectional area, total sapwood area, and current sapwood area at breast height) were investigated in two important bottomland tree species of the southern United States, cherrybark oak (Quercus falcata var. pagodifolia EN.) and green ash (fraxinus pennsylvanica Marsh.). In all models tested and for ...
