The supercritical carbon dioxide extraction (SC-CO2) of fish oil was studied using the viscera and skin of African catfish as a raw material and the CO2 as supercritical fluid solvent. A central composite design of response surface methodology (RSM) was employed to optimize the SC-CO2 extraction variables. The response variable (Y) oil yield was ex

Contact-impact problems are a class of problems that exist in almost all machinery, automotive, aerospace, and structural applications. The contact-impact phenomena is inherently nonlinear and numerous approaches were used to solve such problems. In this paper, we exploit the linear Finite Element formulation within an incremental approach to solve

Objective : To determine the proliferative activity of cervical intraepithelial lesions to assist in the diagnosis and treatment of these lesions through the use of silver stained nucleolar organizer region (Ag +– NOR). Nucleolar organizer regions (NOR) are loops of ribosomal DNA (rDNA) occurring in the nuclei of cells.Cell proliferation under no

Humans have been struggling from the very dawn of civilization to establish an ‘order’ wherein they can fulfil their aspirations, and live with their brethren in peace and harmony with dignity and honour. They have made serious and rigorous efforts in this direction but it still remained only a dream. They thought it could be possible if they c

Knowledge, as a matter of fact, should be universal, applicable, at least, to the most situations but it is seldom possible in case of knowledge about human and social world. It is said that knowledge is, to a great extent, conditioned by existential conditions. This is apparent when the relevance and applicability of social sciences to the rest is

Numerous activities in construction and demolition (C&D) projects are generally considered as complex and distant that may affect surrounding environment and public health. Construction, remodelling, repairing, refurbishing or demotion works of buildings and other infrastructures such as roads generate huge amounts of hazardous and non-hazardou

The original, novel idea behind Tabung Haji’s establishment was to help Malaysian Muslims save for hajj. However, throughout the years, the subsidy amount for hajj pilgrims has proven to be ever-increasing. As a case in point, for the 2020 hajj season, a first-time hajj pilgrim needs only pay RM9980 out of RM22,900 of the original costs. Stated d

Diffusion-reaction problem in a porous solid catalyst is important in the design and analysis of heterogeneous phase reactors and has been extensively studies. However, the effect of intraparticle convection on the substrate transport inside the solid has been scantly reported in the literature, though intraparticle convection plays significant rol

INTRODUCTION: COVID-19 pandemic has caused a major impact to global public health including one of the high risk groups which is the medical students. This study was intended to assess knowledge, attitudes and practices (KAP) towards COVID-19 among medical students in International Islamic University Malaysia (IIUM). MATERIAL AND METHOD: An online
