ABSTRACT Micronutrient deficiency of zinc and iron is a major problem worldwide, especially in the developing countries that heavily rely on cereal rich diets for sustenance. Wheat is a popular staple cereal crop containing substantial levels of micronutrients and could be used as a tool for alleviating their deficiencies. The study reported herein focused on determining the concentration of zinc, iron, resistant starch (RS) and phytic acid in 9 newly released wheat varieties and their effec...
ABSTRACT Consensus of opinion in literature regarding tobacco use has shown that cigarette smoking can cause irreparable damage to the genetic material, cell injury, and the general respiratory landscape. The alkaloid family of tobacco has been implicated in a series of ailments including addiction, mental illnesses, psychological disorders, and mental deficits. Accordingly, this study describes the kinetic and molecular modelling of the major tobacco alkaloids in mainstream cigarette smoke;...
ABSTRACT Suusa is spontaneously fermented raw camel milk prepared by pastoral women and informally marketed in Kenya. Processors, traders and consumers of suusa rely on organoleptic testing for quality and safety along the suusa value chain. Handling practices in raw milk and suusa products potentially exposes the product to microbial contamination which is associated with reduced shelf life and risk of infections to consumers with milk borne and zoonotic diseases such as brucellosis and tub...
ABSTRACT The emergence of multi-drug resistant strains is a formidable threat to the fight against skin diseases and hence effective alternative regimes must be sought. Although many studies have been done on antimicrobial activities of Syzygium aromaticum and Eucalyptus citriodora oils, no information is available on their antimicrobial interaction and hence the purpose of this study. Bioactivity testing of Syzygium aromaticum and Eucalyptus citriodora oils was done using disc diffusion tec...
Abstract This study employs 3D Post-Stack Time-Migrated seismic data from the DN-Field, within the Coastal Swamp depobelt of the Niger Delta in predicting lithofacies and fluvial facies of OVK-1 sand bodies in the Agbada Formation, as a tool to identify new drillable prospects. A lithofacies model for OVK-1 reservoir sand body was generated after upscaling using Most Of, as the averaging method. Calibrated by fluvio-facies at the well locations, channel sands were identified in OVK1 reservoi...
ABSTRACT Ficus plant components have application in traditional medicine because of the myriad uses they have been subjected to. The ease of application is based on the secondary metabolites this plant contains. The challenges faced by modern medicine especially in the complete cure of microbially-associated diseases through abrupt and unpredictable genetic mutations in the presence of conventional drugs informed the investigation of the microbial inhibitory activities of the stem, root and l...
Abstract The Akinbo Formation comprises a sequence of mostly dark, pale-greenish grey, laminated shale, slightly glauconitic shale, sandy shale with subordinate claystone lenses. Selected subsurface samples of the shaly facies as penetrated by Akinside 1582 well in eastern Dahomey basin, were investigated by sedimentological, mineralogical and geochemical parameters to ascertain the hydrocarbon potential and deduce the influence of variations of clay mineral indicators on the prospect. Values...
Abstract Tithonia diversifolia is found growing abundantly within the forest zone of Nigeria. The evaluation of the pulp and paper making properties of T. diverisifolia showed average fibre length, width, wall thickness and lumen of 827.66 186.40m, 20.29 3.92 m, 3.96 0.28 m and 12.16 3.96 m respectively. This short fibre length and small wall thickness of T. diversifolia made it unsuitable for making strong papers. However, it is good material for mak...
Abstract: A geophysical investigation has been performed using Vertical Electrical Sounding (VES) at a site behind Sammy Guest House in Ikere-Ekiti, Ekiti-State to examine the geophysical parameters that can be used to evaluate the structural competence of the shallow section of the subsurface for construction purposes and building development. The schlumberger configuration was used for the data acquisition. The half- currents electrode (AB/2) was used and the quantitative interpretation of...
Abstract The production of acha and cowpea are the complementary food and are produced in large quantities in Nigeria, which are the major sources of protein and carbohydrate respectively. The study was proposed on developed high protein energy complementary foods from the blends of cowpea and acha using extrusion cooking. Cultivars of cowpea (IT90K-277-2) and acha (cream colour) were selected and milled into flours. Using the response surface methodology, the blends of acha and cowpea flours...
ABSTRACT Polyamide-6 (also known as nylon-6) is one of the biodegradation-resistant synthetic polymers used in the manufacturing of commodity plastic materials. The environmental effects of the persistence of this material in landfill and on surface water bodies pose global problems that endanger public health. Knowledge of the microbial distribution and pattern of their interaction with these plastics will provide the biological resources and scientific basis for the development of sustaina...
ABSTRACT The development of resistance to insecticides by Anopheles mosquitoes continues to threaten the success of malaria control programmes in West Africa. Local data on mechanisms and factors causing resistance in the region are scanty. This study was designed to investigate the environmental factors and mechanisms implicated in resistance to pyrethroids by Anopheles gambiae in southwestern Nigeria and southern Benin Republic. Larvae of Anopheles mosquito were collected in 2007 from 19...
ABSTRACT Fermented cassava products like fufu and usi (edible starch) are important staple foods in many African homes. Natural fermentation time is usually long resulting in slower acidification process and inconsistent nutritional composition of products which could be overcome with the use of starter culture. However, most available starter cultures are used for single food fermentation and are uneconomical. This necessitates the development of a starter culture for multiple related food ...
Abstract This paper examined the impact of petroleum exploitation on the environment of the Niger Delta oil producing communities in Nigeria. This is in furtherance of the understanding that human beings are at the centre of concerns for sustainable development. The paper observed that there was need for the adoption of measures that would provide a reasonable degree of protection of ecological and human environment from the activities of the oil industry in Nigeria.
ABSTRACT There has been an increased incidence of hearing -related difficulty due to consistent use of mobile phones, particularly those with multiplicity of functions for continued calls and music playing functions. Thus, this study investigated the incidence and patterns of hearing loss associated with the consistent use of mobile telephone among adolescents in Ibadan Metropolis. The study adopted an ex-post facto research design, sampling 500 adolescents through the use of Hearing and Mob...
