Living organisms require trace amounts of heavy metals, including cobalt, copper, manganese and zinc to survive. However, the excessive levels of the metal can be detrimental to the organism. Other heavy metals such as mercury, lead and cadmium have no vital on organisms, and their accumulation in long time period in the bodies can cause serious il

This study intends to show the effectiveness of hierarchical agglomerative cluster analysis (HACA), discriminant analysis (DA), principal component analysis (PCA), factor analysis (FA) and multiple linear regressions (MLR) for assessing the air quality data and air pollution sources pattern recognition. The data sets of air quality for 12 months (J

The Malaysian government has spent a large amount of money to keep maintaining the quality of Federal roads in Malaysia. In the face of high cost of road maintenance, increasing demands of road users, changing volume of traffic condition, in company with scarce of funds and limited budget allocated, the clients, including the government and private

Hydrogen gas production via glycerol steam reforming using nickel (Ni) loaded zeolite (HZSM-5) catalyst was focused on this research. 15 wt % Ni(HZSM-5) catalyst loading has been investigated based on the parameter of different range of catalyst weight (0.3-0.5g) and glycerol flow rate (0.2-0.4mL/min) at 600 ºC and atmospheric pressure. The produc

Consistent awareness, integration and revisiting the missions for improvement towards sustainability of higher education need attention. Mediating roles of higher education institution leaders can enhance the improvement, through awareness on sustainable education and quality integration in administrative performance. Mediating roles of leader make

We investigated the dispersion structure of the hole subbands in vicinal Si(111)4 ' 1-In surfaces directly by angle-resolved photoelectron spectroscopy. In this study, three inversion layers with different impurity concentrations and numbers of times of flash annealing (FA) were investigated. We observed wider energy separations of subbands lev

It is undoubted that we are now living in turbulent era where teaching-learning and administration of higher education institutions (HEI) are facing many difficulties. This is because everything is growing at a fast pace and the future is uncertain. Revisiting the mission of higher education and achieving sustainability in HEI are lacking attention

A study of organic loading rate (OLR) and effect of NaOH concentration on the pretreatment stage of corn husk (CH) was conducted by Face-Centered Central Composite Design (CCF) to improve the biogas production. Three levels of OLR at 25.0 g VS · L–1 · d–1 (OLR25), 35.0 g VS · L–1 · d–1 (OLR35), and 45.0 g VS · L–1 · d–1 (OLR45) we

Osteomyelitis in children has various clinical manifestations causing diagnostic and therapeutic difficulties. Inappropriate treatment of acute osteomyelitis may lead to chronic, serious and complicated condition. Chronic osteomyelitis continues to be a major cause of morbidity and disability in children living in developing countries. We present t
