In this work, a statistical model which can be used to evaluate the removal of chromium from aqueous solution using chitosan as an adsorbent has been developed. The experiment was described by varying chitosan dosage (10-30 mg), pH (5-8), contact time (10-90 min) and agitation speed (50-250 rpm). The initial chromium concentration was fixed to 20 m

The universities and education face great challenges, most of them indirectly or directly related to science. Academic honesty and integrity are fundamental values in a community of scholars. The student shares with the faculty the responsibility for maintaining the integrity of scholarship, grades, and professional standards, therefore students at

Malaysia is a country with luxurious agricultural resources. However, without proper management, the waste resulted from processing activities of these agricultural process will lead to a major waste problem. This study involved the utilization of the palm kernel shell (PKS) activated carbon by performing the decolorisation of malachite green color

Elemental (metallic) mercury primarily causes health effects when it is breathed as a vapor where it can be absorbed through the lungs, at higher exposures there may be kidney effects, respiratory failure and death. This study aimed to study the performance of carbon nanotubes (CNT) grown on granular activated carbon (GAC) as an adsorbent for remov

Available composting models do not describe accurately the dynamics of composting processes. Difficulty in modeling composting processes is attributed mainly to the unpredicted change in process rate caused by change in activation energy value (E). This paper presents the results of an attempt made to utilize patterns of change in carbon, nitrogen

Digital Storytelling (DS) has been popular in education since the 1990s, however, the use of DS with Augmented Reality (AR) technology in teaching the Seerah (History of the Prophets) subject in school is scarce. AR is one of the most evolving technologies that is being implemented in various fields such as military, medical, advertising, entertain

The study is to examine the impact of HR practices on organizational commitment and turnover intention. Four hundred and fifty seven employees from various industries in a region in one of the states in Malaysia participated in the survey. HR practices were measured using employees’ perception on career management, person-job fit, compensation an

A mathematical modeling of bioconversion of domestic wastewater sludge for cellulase enzyme production was constructed based on the ideal batch mode. The mathematical models was based on the mass balance equation and focused particularly on the biomass, substrate and product rate of reaction. The biomass, substrate and product considered in this pr

The sinterability of hydroxyapatite (HA) powder synthesized through a novel wet chemical method (HAp) and a wet mechanochemical method (HAwm) was investigated over a temperature range of 1000oC to 1400oC in terms of phase stability, bulk density, hardness and fracture toughness. The results indicated that the sinterability of HAp powder were signif
