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

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

Mercury is a heavy metal and is used widely in the industry, making it a global problem. It accounts for approximately 70% of man-made emissions. Activated carbon was found to be efficient for the adsorption of Hg(ll) in aqueous solution. The characterization of Hg(ll) uptake showed that the mercury binding is dependent on initial pH, agitation spe

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 article presented the results of an attempt made to utilize patterns of change in carbon, nitrog

This chapter investigates about the contribution ofIbn-Sina in pharmaceutical sciences. Ibn-Sina was the most famous physician, philosopher, encyclopaedist, mathematician and astronomer at his time. The objective of this chapter is to investigate the contribution of Ibn-Sina in pharmaceutical sciences through his book; The Canon of Medicine. Ibn-Si

An effort was made to assess the utility of 650 bp partial Cytochrome C oxidase subunit I (DNA barcode) gene in delineating the members of taxonomically ambiguous marine fin fishes (Family: Mugilidae). To address the issue we used all the 95 barcode sequences of Mugilidae family available at NCBI (National Centre for Biotechnological Information) a

There are at least four large-scale, global, environmental parameters that, spatially and temporally, set limits on the distribution of horseshoe crabs. Of these, continental geomorphology and temperature regimes are two major constraints on the wide spread distribution of horseshoe crabs. Basically, the continental shelves define the areas availab

In this paper a new approach that generates a general algorithm for n-link hyper-redundant robot is presented. This method uses repetitively the basic inverse kinematics solution of a 2- link robot on some virtual links,where the virtual links are defined following some geometric proposition. Thus, it eliminates the mathematical complexity in compu

"Mus'ab 'bmay~, The Great Martqr of the Muslim Nation" as developed by using tu o-dimensional animation n hich focuses on Islamic History. This story as most detailed and fascinated about one of the companions of prophet Rasulullah (S.A.W) and his contribution and sacrifice tonards Islam. It is an edutainment that targeted audience

Psychophysical studies are elemental ways to describe sound perception which includes the identification of perceptual differences in children, young and older adults. This study summarizes various psychophysical abilities with aims to provide better understanding in the perceptual development of normal hearing subjects. This study investigated fre
