A recent rise in crab aquaculture activities has intensified the generation of waste shells. In the present study, the waste shells were utilized as a source of calcium oxide to transesterify palm olein into methyl esters (biodiesel). Characterization results revealed that the main component of the shell is calcium carbonate which transformed into

Aquaculture activity has increased the population of crab, hence increasing the generation of related wastes, particularly the shell. In addition, the number of molting process in crabs compounds further the amount of waste shell generated. As such, in the present work, the application of the waste crab shell as a source of CaO in transesterificati

In the crystal structure of the title compound, C11H16N2O3, molecules are linked by one O—H� � �N and two N—H� � �O intermolecular hydrogen bonds into a three-dimensional network, which incorporates R22(14) and R22(16) graph-set motifs.Ethyl 3-amino-4-[(2-hydroxyethyl)- amino]benzoate Natarajan Arumugam,aAisyah Saad Abdul Rahim,a‡

Bilateral vocal cord palsy is almost always caused by neck surgery, particularly surgery of the thyroid. We report a case of bilateral vocal cord palsy requiring emergency surgery to relieve the airway obstruction as the sole presentation of acquired syphilis. As the incidence of syphilis worldwide is rising, this unusual presentation may give clin

Phonophobia and hyperacusis are two separate but closely related symptoms that are often mistakenly used in clinical practice as the same entity. Here we present a case report to highlight the distinguishing features of both and discuss the steps of management in these conditions. It is vital for the attending doctors to recognise hyperacusis and p

Salam 1 Malaysia The Audiology Unit, Department of ORL-HNS, International Islamic University Malaysia in collaboration with the MMA (Pahang branch) and the Kuantan Municipal Council had successfully organized a charity event called Kuantan Biggest Morning Tea. The event was held in Taman Gelora, Kuantan on 8/8/2010. The main aim was to promote and

Introduction: This chapter confines itself to strictly legal issues arising form the cases of Aishah Azmi and Shahina Begum, with some comments on the recent use of 'X' as well as, peripherally, some related aspects......

The aim of this study is to prepare a model for the production of Newcastle disease virus (NDV) lentogenic F strain using cell culture in bioreactor for live attenuated vaccine preparation. In this study, firstly we investigated the growth of Vero cells in several culture media. The maximum cell number was yielded by culture of Vero cells in Dulbec

Oil-laden spent bleaching clay (SBC) is currently under-utilized by dumping it in landfills without any attempt to recover the oil. Therefore, effort has been made to extract the waste oil using different solvents (methanol, ethanol, petroleum ether, and hexane), and utilize the oil in transesterification reaction. Cleaner oil (free from polar comp

Studying the influence of the operating parameters on membrane fouling is important in fouling control. This paper presents the interaction effects of the sludge retention time (SRT), organic loading rate (OLR) and feed temperature (Tf) on membrane fouling. A submerged membrane bioreactor (SMBR) was operated under a constant flux (11.1 l/m2 h), wit
