Crude oil and natural gas contain acid gases (H2S and CO2) and associated impurities, such as benzene, toluene and xylene (BTX) that are all harmful to human health, environment and industrial equipment. It is often required to process crude oil and gas using highly efficient desulfurization processes prior to use as a fuel. The separated acid gases (byproducts of desulfurization) are further processed in Claus process plants to recover chemical and thermal energy. Currently, BTX and other associated impurities present in acid gas cause several technical and operational problems that result...

Both HIV and Tuberculosis infections are associated with lipid peroxidation and antioxidant imbalance. Pathology of the two produce free radicals which lead to lipid peroxidation indices one of which is Malondialdehyde (MDA) and to disease progression due to CD4 cells apoptosis. The study was carried out with the objective of determining Serum MDA, Vitamin E, CD4, CD8 and lipid peroxidation index (LPI) in four different subgroups comprising of HIV, Tuberculosis and HIV/TB co-infected patients and the Controls with a view to assessing the interaction between oxidants and antioxidants in the...

Values of peak expiratory flow rate (PEF), ECG and Hematological variables in 250 females at their reproductive ages, made up of 123 pregnant subjects and 127 non-pregnant control group, living and/or working in kura local government area and its environs were obtained. Pearsons correlation coefficient between PEF and ages as well as ECG, Hematological and other anthropometric measurements were calculated in both groups.Multiple regression analyses were made to obtain the best prediction formula using the measured variables in pregnant and non-pregnant groups. Furthermore, graphs were...

This book originated from papers presented at an international Conference organised by Arewa House, Centre for Historical Documentation & Research of Ahmadu Bello University, Kaduna in collaboration with the United States Embassy in Abuja. Held on March 7th 2007 to kick start a major project on the preservation, digitization, procurement and conservation of the rich Nigerian ancient Arabic/Ajami manuscripts Heritage for the development of new knowledge. A recent survey conducted by Dr. Angel Batiste of the Library of Congress Washington DC in 2007 has proved beyond reasonable doubt of the...
