Production of non shredded empty fruit bunch semi-compost
(The Institution of Engineers, Malaysia, 2010-12)Composting of the empty fruit bunch (EFB) with the palm oil mill effluent (POME) could simultaneously treat the solid and liquid waste from palm oil mill. With the aim to reduce the composting yard area, production of ... -
Proposed strength and stiffness parameters for normally consolidated and overconsolidated Dhaka clay
(The Institution of Engineers, Malaysia (IEM), 2012-03)The undrained shear characteristics of reconstituted normally consolidated and overconsolidated samples of Dhaka clay are discussed. The disturbances on the soil structure result from sample penetration that reduces the ... -
Pulsating circular air jet impingement heat transfer
(The Institution of Engineers, Malaysia, 2006-09)The purpose of this study is to determine the effect of pulsating frequencies on the local and average heat transfer characteristics of a heated circular air jet. Pulsation of the air jet was produced by a rotating cylinder ... -
Reactions of used motor oil and residual oil using mesoporous MoAI₂O₃ catalyst
(The Institution of Engineers, Malaysia (IEM), 2013-06)In the present study, mesoporous Mo-based catalysts of different pore size ranges were synthesized and investigated for its hydrocracking activity. Catalyst pore size has been considered a property affecting the_mass ... -
Reinforced concrete strength at slab and column intersection
(The Institution of Engineers, Malaysia (IEM), 2017-12)This paper proposes a method modified from that as first suggested by Siao1 to determine the effect on column strength taking into consideration the effect of confinement by the surrounding slab. Previous test results2-4 ... -
Remediation of Heavy Metal Contaminated Soil by Using Chemical Stabilization
(The Institution of Engineers, Malaysia, 2004-03)The effectiveness of ordinary portland cement (OPC) in the immobilization of heavy-metal contaminated soil was investigated in this study. Heavy metal contaminated soil was collected from a scrap metal yard within the ... -
Removal of E.Coli and turbidity using riverbank filtration technique -RBF- for riverside alluvial soil in Malaysia
(The Institution of Engineers, Malaysia (IEM), 2016-06)Riverbank filtration (RBF) is an efficient and low-cost natural alternative filtration technology for water supply application. In this method, the surface water contaminants are removed or degraded as the infiltrating ... -
Resilient modulus of Malaysian base and subbase pavement materials
(The Institution of Engineers, Malaysia, 2008-06)Pavement design approach is shifting towards analytical or mechanistic-based procedures. Resilient modulus is a fundamental parameter used in the procedure and a study was carried out to characterise the parameter for base ... -
Review of active power filter technologies
(The Institution of Engineers, Malaysia, 2007-06)Active power filters (APF), are increasingly used to mitigate harmonics in utility power lines. Compared to the more established method such as the static var compensator or passive filtering, APF are relatively new in ... -
Review of fire-related assessment damage of steel off shore structures
(The Institution of Engineers, Malaysia (IEM), 2021)Fixed offshore structures are continuously exposed to risk of hydrocarbon fire or cellulosic fire. Hydrocarbon fire generally causes more detrimental effect than cellulosic fire because the rapid increment of temperature ... -
A review of nanoporous materials derived from Covalent Organic Frameworks
(The Institution of Engineers, Malaysia, 2010-09)The implementation of nanoporous materials is becoming increasingly more prevalent due to their unique characteristics, which make them highly applicable in a multitude of different functionalities. Covalent Organic ... -
A review of natural products from plants using carbon dioxide supercritical fluid extraction
(The Institution of Engineers, Malaysia (IEM), 2020)Supercritical fluid extraction (SFE) is the most effective and efficient way to extract valuable constituents from plants. SFE is the process of separating one component (the extractant) from another (the matrix) using ... -
