Development of Extruded Complementary Foods from Blends of Acha . land Cowpea Flours

ABSTRACT Despite the fact that a variety of improved traditional African complementary foods have been developed from cereal-legume blends (1,2), the traditional products that are a leading cause of protein-energy malnutrition, still remain the primary weaning foods, especially in rural communities, largely because of the high cost of improved complementary foods, The ingredients for low-cost complementary foods must be derived from dietary staples available and affordable in the region of in...

Candidaemia or Candidasis: Controversy of Staphylococcus Sexually Transmitted Infection?

ABSTRACT Herbal medications are becoming increasingly popular but a most-extraordinary claim by traditional/herbal medical practitioners relates to a Gram-positive bacterium, Staphylococcus, which has been depicted as a deadly sexually transmitted disease that manifest in the form of worms and other symptoms; with contributory roles including infertility, sexual dysfunction and impotency. They further boasted that they are the only ones that possessed the remedy (herbal) for the Staphylococc...

FLORISTICS AND STRUCTURE OF THE REMNANT FORESTS OF THE OBAFEMI AWOLOWO UNIVERSITY CAMPUS, ILE-IFE NIGERIA AND THEIR POTENTIAL FOR CONSERVATION

ABSTRACT The floristic composition and the girth sizes of the woody plants in seventeen sample forest plots at the Obafemi Awolowo University, Ile-Ife, Nigeria were studied with a view to making recommendation on the conservation of the forest. The 120 species found are those typical of drier lowland forest of south Nigeria. Twenty-six species occurred in 8 of the 17 plots while 28 occurred in one plot and could be regarded as rare. About 70% of the stems are less than 30 cm girth at breast h...

ISOLATION AND CHARACTERIZATION OF BIOOXIDIZING BACTERIA FROM THE OBUASI GOLD MINING SITE

ABSTRACT Processing o f gold arsenopyrite and sulphide ores is currently done with biooxidizing bacteria. This procedure is preferred because of its environmental friendliness and efficiency o f gold recovery from ores, compared to the conventional methods. The efficiency of biomining is, however, largely influenced by the origin o f biooxidizing bacteria used and local organisms have been found to be better adapted to extracting gold from the ore from which they were isolated. The work repor...

HUMAN METAPNEUMOVIRUS AND RESPIRATORY SYNCYTIAL VIRUSES IN GHANAIAN CHILDREN BELOW FIVE YEARS WITH ACUTE LOWER RESPIRATORY TRACT INFECTIONS IN ACCRA, GHANA

ABSTRACT Acute lower respiratory tract infection (ALRTI) in children under five years is predominantly cause by Respiratory syncytial virus (RSV) but in recent times Human Metapneumovirus (HMPV) has also been implicated in ALRTI. In Ghana, the few studies on ALRTI have focused on the prevalence of RSV and the viral etiological agents causing acute bronchiolitis, bronchopneumonia and pneumonia. This cross sectional study sought to detect, characterize and genotype respiratory syncytial virus ...

STABILISATION AND CHARACTERISATION OF A PEANUT BASED READY-TO-USE SUPPLEMENTARY FOOD (RUSF)

ABSTRACT The prevalence of under nutrition in many communities requires the need for the availability of nutrient dense affordable food supplements such as Ready-to-use supplementary foods. An energy dense, drinkable ready to use supplementary food produced by enzyme hydrolysis of cooked mixture of peanuts, cowpeas and rice with added vitamin mineral mix was both acceptable to consumers and showed promise of efficacy in improving the nutritional status of women of child bearing age through ...

WAVELENGTH MODULATION ABSORPTION SPECTROSCOPY WITH 2f SIGNAL DETECTION: APPLICATION TO MOLECULAR OXYGEN DETECTION

ABSTRACT Wavelength modulation spectroscopy using second harmonic (2f) signals is one of the modulation techniques in absorption spectroscopy used to improve the absorption signal by noise reduction. This second harmonic (2f) signal has been simulated using MATLAB, a new approach based on numerical integration, to investigate the influence of normalized modulation amplitude, m and the optimal 2f signal was found to occur at m = 2.1. Experimentally, free molecular oxygen gas was measured at th...
