ABSTRACT The improvement of the combustion properties of coal and biomass by blending and carbonization was investigated. Proximate and ultimate analysis of coal, sawdust, corn cob and their blends were carried out using ASTM methods. The proximate and ultimate analyses were repeated on the five blends after carbonization at 500oC for one hour. Ten mixtures of coal-sawdust and coal-corn cob blends were made into briquettes using starch binder. The calorific values of the samples were determin...
ABSTRACT Dyes from Pterocarpus osun Craib and Lawsonia inermis Linn. were extracted using ethanol and methanol respectively. The extracted dyes were subsequently purified using chromatographic methods. Purified pigments were characterized using Ultra-Violet Visible Spectrophotometer, Fourtier Transform Infrared Spectrophotometer and Lovibond Tintometer. The UV spectra of the dyes in petrol, kerosene and diesel showed presence of chromophores. The FTIR spectra of the dyes showed presence of ph...
ABSTRACT Five species of Mushroom namely Termitomyces robustus, Agaricus bisporus, Pleurotus tuber-regium, Amanita phalaoides and Amanita verosa were collected from eleven locations in Uke, Abatete, Ideani, Nnobi, Nnewi (Okpuno-egbu), Nnewi (Umudim) and Ozubulu between 2009 and 2012 in Anambra State, Nigeria. They were kept in clean collection bags and identified by a taxonomist. Some of the mushroom samples were later oven dried at 75 0 C for 4 hours and kept for chemical analysis while some...
ABSTRACT Game theory has been used to study a wide variety of human and animal behaviours. It looks for states of equilibrium, sometimes called solutions. Nash equilibrium is the central solution concept with diverse applications for most games in game theory. However some games have no Nash equilibrium, others have only one Nash equilibrium and the rest have multiple Nash equilibria. For games with multiple equilibria, dierent equilibria can have dierent rewards for the players thus causing ...
ABSTRACT The study focused on the Preventive aspects of malaria in pregnancy in Badagry Local Government Area, one of the 20 LGAs in Lagos State in Southwestern Nigeria. The objectives of the study were to determine the knowledge, attitude and practices of the community on malaria; determine the effectiveness of Intermittent Preventive Treatment in pregnancy (IPTp) using Sulfadoxine-pyremethamine (SP) [IPTp-SP] in the prevention of malaria; and ascertain the safety of SP during pregnancy by ...
ABSTRACT Selected agro-wastes found in Lagos, Nigeria (cassava peels, corncob, sawdust, and sugarcane pulp) were compared with glucose and lactose as microbial substrates for cultivating P. chrysogenum (wild strain). This study was designed to give added value to agro waste as substrates to cultivate P. chrysogenum and subsequent production of secondary metabolite with antibiotic and anticoagulant properties. In the growth studies, corn cob and cassava peels significantly (p < 0.05) produced...
ABSTRACT The potential of alkaloids from Panicum maximum floret infected with the fungus Tilletia ayresii in the control of uterine contraction in Sprague-Dawley rats was investigated using bioassay guided fractionation technique. Disease incidence study revealed that smut disease was significantly higher in Ikorodu site (95.00%) when compared with Akoka site (69.00%) and Isolo site (72.00%). The height of disease incidence was between the months of August and November. Thirteen species of f...
ABSTRACT In October 1993, Kenya adopted a floating exchange rate system where the exchange rates are determined by forces of demand and supply for the local currency. Exchange rate forecasts are necessary to evaluate the foreign denominated cash flows involved in international transactions. Therefore exchange rate forecasting is important to evaluate the benefits and risks attached to the international business environment. This study therefore sought to fit a Seasonal Autoregressive Intergra...
Abstract In this paper we study the eects of magnetohydrodynamics (MHD) uid ow on a two dimensional boundary layer ow of a steady free convection heat and mass transfer on an inclined plate in which the angle of inclination is varied. The uid is taken as viscous, incom- pressible, electrically conducting. The mathematical formulation yields a set of governing partial dierential equations (PDEs) under a set of appropriate boundary conditions. The PDEs are transformed into ordi- nary die...
ABSTRACT Malaria is the main cause of paediatric morbidity and mortality in holoendemic areas. The populations in these areas have similar transmission intensity and infection rates of Plasmodium falciparum malaria but present different malaria outcomes. The cause of the different clinical outcomes is poorly understood. Pf. has exerted selective pressure on the human genome leading to genetic variability in the host’s immune response genes mediating protection and susceptibility to Pf. mala...
Several community milk cooling plants were constructed and equipped in Western Kenya counties through joint funding of the World-Bank and the Government of Kenya between the years 2008 to 2016 to promote milk production and marketing. A recent study revealed that utilization of these milk cooling plants and farmer participation was low. Market participation in sub-Saharan Africa has been assessed mainly based on already producing households without considering decision to produce by non-produ...
ABSTRACT Chloroquine was the mainstay of antimalarial chemotherapy because of its safety profile, effectiveness and the relatively cheap cost. However, the emergence of chloroquine-resistant Plasmodium falciparum parasites has rendered this drug ineffective in most regions where malaria is endemic. Most antimalarial drugs that act through blood - stage - specific mechanism are no longer effective due to the rapid emergence of drug resistance while the costs of development of new drugs continu...
Abstract The aim of research study is to construct a web based system that enables customers to order products and services online.

The enhanced newspaper subscriptions payment platform project will provide benefits for the organisation by implementing a computerised system of the manual subscription process being used cur...
ABSTRACT Rotavirus is the most common cause of severe gastroenteritis infection in infants and young children, occurring even with very high standard of hygiene. The disease spreads by contact with infected faeces and might also be transmitted through faecally-contaminated: food, water and respiratory droplets. Rota teq and Rotarix are the two licensed oral vaccine intervention for rotavirus. However, it takes time for the development of vaccineinduced immunity to complete, hence the need to ...
