Durian peel is among the renewable biomass wastes abundantly available in Malaysia. An implication of untreated biological materials for biosorption process was intensively reported, that prioritize our work towards sorbent modification. The biosorption potentials of hydrochloric acid (HCl) modified durian peels (HAMDP) for removal of Zn (II) from

Ripraps, land reclamation and fishing jetty renovation were perturbing Balok Beach shores between the years 2011 and 2013 and visible impacts were scaled using horseshoe crab spawning yields. Initially, placement of ripraps at Balok Beach effectively reduced erosion and created a suitable spawning ground for the horseshoe crab, Tachypleus gigas. Ho

This qualitative study aimed to diagnose the challenges facing teachers of the (A2) program for the Arabic language in developing 21st century learning skills among students of the Arabic language in Comoros high schools. The 21st century imposes an interest in acquiring students the skills that can help them solve their learning problems, prepare

To date, the Smoothed Particle Hydrodynamics (SPH) method which is mesh-less and fully Lagrangian in nature has been mainly applied in solving solid heat conduction problem and flow convection problem separately. In the current work, we have implemented the Weakly Compressible Smoothed Particle Hydrodynamics (WCSPH) method to solve internal flow pr

Biosorption of Lead Pb(II) on durian husk activated carbon (DHAC) was investigated in this study. The effects of operating variables such as pH, biosorbent dose, temperature, initial metal ion concentration and contact time were studied using response surface methodology (RSM). The experimentation was performed in two sets, namely; set 1 and set 2.

In this paper, a multiband stack series array antenna is designed in order to attain solutions for the future 28 GHz Ka-band application. Double layer substrate Technology is utilized to accomplish multiple resonant frequencies with higher data transfer capacities due to high bandwidth. The designed antenna is dependent on twofold layer consisting

Carcinoscorpius rotundicauda is mangrove horseshoe crab that inhabit in mudflats ecosystem. The values information on morphometric variability of C. rotundicauda is still limited especially along west coast of Peninsular Malaysia. A total of 148 samples of C. rotundicauda were collected randomly from Merlimau, Melaka and Pendas, Johor characterized

Lead contamination present in wastewater is one of the major problems due to its toxicity and persistence. This issue increased dramatically and led to the environmental and health concerns worldwide. Therefore, this study aims to remove lead from synthetic wastewater effluent by adsorption process. In this study, nanomaterial called graphene oxide

Herbal medication and natural products has been successfully demonstrated to have general health beneficial effects. The bioactivities of flaxseed (linum usitatissimum) extract have been reported, as previous studies have shown that l. usitatissimum extract has many health and beneficial effects such as antimicrobial, anti-oxidant and anti-inflamma
