ABSTRACT Water as an essential commodity plays a major role in national development, the availability of water through pipe borne to individual, communities, and the country at large will help in achieving the New Millennium Development Goal (MDG7), hence the constant study, analysis and forecast for supply of water using past water supplied. The supply of pipe borne water from 2009 to 2015 was examined with the aim of developing a working model to forecast future supply of pipe borne water...
ABSTRACT Stillbirth remains a public health problem with an estimate of 2.6 million stillbirths in 2015 of which 98% occurred in low- and middle-income countries and over three-quarters of these occurring in Sub-Saharan Africa (SSA) and south Asia. Further, only ten countries carry the burden of over 65% of total stillbirths in the world including Nigeria in the second position. The objective of this analysis is to estimate stillbirth rates and identify the determinants of stillbirth in Haji...
ABSTRACT Qualitative Petrophysical Analysis of Wabi 10 well, located in the Wabi Oil Field in the Niger Delta was carried out. The wire-line log comprising of gamma rays, resistivity and neutron – density logs provided by Total Exploration and Production Nigeria Limited (TEPNL) was used. The properties considered include Lithofacies, the Permeable and Impermeable beds with their b...
ABSTRACT The primary aim of this project is to estimate the long run relationship between economic growth and currency devaluation. This project investigated the impact of currency devaluation on economic growth of Nigeria. This was achieved through a review of literature. In order to generate the necessary data for this research, the Central Bank of Nigeria Statistical Bulletin of and publications of the National Bureau of Statistics were used for the period of 2008 to 2017. The error co...
The effects of infestation by Callosobruchus maculatus on the chemical, nutritional and sensory properties of three cowpea varieties were investigated. Proximate analysis showed that infestation led to an increase in moisture content by 28.6% on the average. Decreases of 10.6%, 46.5% and 11.4% in crude protein, ash and soluble carbohydrate content respectively were observed. For the three cowpea varieties, the minerals sodium, calcium and magnesium decreased by 6.7%, 10% and 1.3% respectively...
Raw and boiled water yam tubers (Dioscorea alata) were analyzed for proximate contents such as ash,crude protein, carbohydrate, crude fibre, crude lipid, energy and anti-nutrients using standardprocedures and methods. The crude protein contents (10.27%), ash (2.93%) and lipid (0.15%) weresignificantly (p
Abstract— Raw Azdirachta indica seed oil is gradually adopted by local farmers as a protector of stored grains and legumes against the common insects, but with some reservations on its safety. The study investigated the safety A. indica on mammalian objects using haematological and antioxidant indices. A. indica seed was obtained from the trees in the same location in Utu Ikot Ukpong, Essien Udim Local Government Area, Nigeria. The Albino rats were obtained from the Animal House of Bioch...

AbstractGums were extracted and purified from Colocasia esculenta and Detarium microcarpum.Rheological properties ofthese gums in comparism with a standard,Gum Arabic were determined.Result showed that gums from D.microcarpum(0.0113cps) and C.esculenta (0.0110cps) exhibited Newtonian characteristics and had higher apparent viscosity than GumArabic (0.0109cps).These gums exhibited shear thickening characteristics when apparent viscosity was plotted against shearrate.Density values for extracte...
AbstractNutritional quality and hematological indices of rats fed biscuits made from wheat flour fortified with casein,soybean and Bambara groundnut flours were investigated. Wheat flour (WF) was blended in each case with cooked,blanched and cooked/blanched soybean (SF) and Bambara groundnut (BGF) flours in the ratios of 70:30 (WF:SF) and 70:30(WF:BGF), respectively and used for the production of short soft dough biscuits. The resulting biscuit flours were used forthe formulation of test diet...
Identification and quantification of carotenoids from yam and cocoyam were evaluated after different processing methods. Seven carotenoids were identified by HPLC-DAD both in the raw and processed tubers. The mean carotenoids in yam, D. cayenensis was α-carotene (0.78 µg/g), 9-cis-β-carotene (0.71 µg/g), all-trans-β-carotene (1.28 µ g/g); in D. bulbifera was lutein (1.53 µg/g), 9-cis-β-carotene (0.39 µg/g), all-trans-β-carotene (0.19 µg/g). Cocoyam, X. maffa (Scoth) had lutein (0.9...
Yam is an important crop in Nigeria, where it is produced both as food and cash crop. Fusariumrots of yam are among the most important postharvest pathogens of yam worldwide, causing a lotof postharvest losses in stored yam tubers. Lactic acid bacteria (LAB) lower the pH and create anenvironment that is unfavorable to pathogens and spoilage organisms. In vitro inhibition offusarium spp by LAB was investigated; mono-culture and multi-culture were used. The inhibitiontests were carried out with...
ABSTRACTThis research was conducted to evaluate the changes in β-carotene (the major pro-vitamin A) associated with processing of sweet potatoes, Total β-carotene of a sweet potato cultivar (Ex-Igbariam) was quantified using High Performance Liquid Chromatography (HPLC). The level of retention (%R) of β-carotene was calculated. The all-trans and cis isomers of β-carotene were also quantified. Processing methods used were boiling, roasting, deep fat-frying and oven drying. β-carotene rete...
The aim of this study was to investigate the effects of ambient temperature storage (29±2°C) and domestic processing on the carotenoids, chlorophylls, vitamins and minerals in Pterocarpus mildbraedii leaves. Total β–carotene was determined spectrophotometrically while HPLC was used for detailed analysis of carotenoids. The results indicated that P. mildbraedii was rich in lutein (261.96µg/gdwt) and Total –β – carotene (83.53µg/gdwt). Cooking and storage significantly (P>0.05) in...
Abstract The functional, chemical and sensory properties of pasta produced from two varieties of cassava NR8082 flours and TMS 419 enriched with African yam bean was studied. The soybean flour was mixed with cassava flour for pasta production in the following ratio for the two varieties: 20:80, 40:60, 50:50 and 0:100.Variety TMS 419 gave a higher water absorption capacity. The emulsion capacity, foam capacity, pH, absorption capacity, swelling index, wettability, percentage carbohydrate, fa...
