ABSTRACT Nano titanium dioxide (TiO2) has been found to possess enhanced antibacterial properties and has thus been employed in various photocatalytic applications. Studies have confirmed higher photocatalytic activity when the TiO2 photocatalyst is doped with silver (Ag). The reported enhancement is due to valence band electrons being excited at longer wavelengths, hence extending absorbance further into the visible light region. For nano catalysts that interact in such a region, they are te...
ABSTRACT The genus Synsepalum is represented by three species in Nigeria. It is confined to the lowland rainforest region of the country.
Version:0.9 StartHTML:0000000105 EndHTML:0000004603 StartFragment:0000000141 EndFragment:0000004563 The microbial and chemical compositions of some indigenous foods of Southeastern Nigeria (Imo and Anambra States) were investigated. The total aerobic plate count (TAPC) for Ogiri ranged from 1.2 x 1010 to 2.4 x1011 cfu/g, the coliform count ranged from 2.1 x101 to 9.8 x102 cfu/g, and fungal count ranged from 1.0x108 to 3.3x1011 cfu/g. Aniga had a mean TAPC of 1.4x1011 cfu/g, coliform count...
ABSTRACT A sociological and techno-economic survey of komi processing was carried out in the Accra-Tema metropolis. The results indicated that the Komi industry is essentially controlled by women in their prime of life having very little or no formal education. Men play a supportive role. Production is on small-scale and profit margin generally increases with increase in quantity of maize used per batch of komi. The industry is heavily dependent on household hands and locally fabricated and m...
ABSTRACT The movement of contaminated fluid from a solid waste landfill into a portable water aquifier located beneath is an example of underground flow.
ABSTRACT The potentials of large scale solar photovoltaic power generation in Sokoto State, North-Western Nigeria and Port Harcourt, Southern Nigeria were evaluated through the application of solar PV Sys computer software. Daily average solar radiation in both locations and average relative humidity from 2001 to 2010 was obtained from Nigerian Metrological Weather Forecast Centre, Abuja. The data together with recorded Minimum/Maximum Temperatures were applied as simulation input param...
ABSTRACT Diabetes Mellitus (DM) and Thyroid Dysfunction (TD) are the two most common endocrinopathies seen in general population. Type 2 diabetes mellitus(T2DM) is commonly associated with altered thyroid function. The aim of the research is to evaluate TD in patients with T2DM attending Endocrinology Clinic of UsmanuDanfodiyo University Teaching Hospital, Sokoto. Blood samples were collected from 80 Type 2 diabetic patients and 80 non-diabetics (control) and analyze for fasting blood s...
ABSTRACT This study deals with the reliability and availability characteristics of two different systems, the second system differs from the first system due to the additional feature of preventive maintenance. Reliability and Availability analysis of system having one active unit and one warm standby unit with self-reset function and one maintenance facility. The failure unit is repaired through self-reset or maintenance according to different failure model.( Mean Time to System Failure...
ABSTRACT Premix was formulated from cowpea flour, pepper powder and onion powder by mixing the ingredients together by mixing this was then packed.
ABSTRACT One of the major problems of multiple linear regression analysis is multicollinearity of the independent variables. The existence of multicollineariity on climate variables such as relative humidity, solar radiation, rainfall, sunshine and temperature on the response of agricultural output may lead to inflation of standard error of the regression coefficients or false non-significant p-value. In this study, monthly data spanning from 1980-2012 obtained from the Nigeria Institute...
Subsurfaces samples of predominantly carbonate Ewekoro Formation, obtained from the Ibese core hole, in the eastern Dahomey Basin, were examined based on petrography and geochemistry indices.
ABSTRACT The study was carried out to determine the effect of drying methods on the nutrient contents of Moringa oleifera at the Agric. Chemical Laboratory (Usmanu Danfodiyo University Sokoto) and The Energy Research Field of Sokoto Energy Center, Sokoto. Fresh leaves were collected and cleaned then dried using different drying methods viz. shade drying, solar drying, oven drying and sun drying. The treatments were analyzed for proximate and mineral contents using standard methods. Sta...
ABSTRACT The Black-winged Stilt (Himantopus himantopus) is one of few waterbird species that breeds in wetlands on the coast of Ghana. In recent times, its population has seen an increase on Ghana’s coast while other species are declining. The overall aim of the study was to investigate and document the breeding and foraging ecology of the Black winged Stilt in Ghana. The breeding ecology, diurnal time-activity budget and foraging behaviour of Black-winged Stilts were studied at the Densu D...
ABSTRACT In steady ows, the notion of boundaries separating dynamically distinct regions is not ambiguous. This is because the invariant manifolds of time-independent ows and the critical points of time-periodic ows provide adequate information to determine the behaviour of the solutions of these systems. However, for time dependent systems, it is strenuous to determine the nature of their solutions due to their dependence on time. Nevertheless, it was observed that just like steady ows, most...
ABSTRACT Background: Influenza B viruses are receiving attention lately perhaps due to the degree of haemagglutinin (HA) antigen mismatching between vaccine composition strains and circulating strains. Neuraminidase inhibitor (NI) antiviral has also been implicated in prophylaxis and treatment of severe cases of influenza diseases. However, mutations in the two major surface glycoproteins, HA and nueraminidase (NA) could cause the virus to escape host defence mechanisms leading to failure of ...
