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...
Abstract The proximate, dietary fibre, mineral and antinutrient compositions of Gongronema latifolium (leaves), Gymnema sylvestre (leaves), Corchorus olitorius (leaves) and Bulchozia coriceae (seeds) were evaluated. Diabetes was induced in selected albino rats while the control groups were normal. Both groups were fed diets containing different levels of each plant product (0, 2.5, 5.0, 10.0 and 20.0% respectively) for twenty-eight days. Effects of plant products on blood glucose, sodium, pot...
ABSTRACT Electronic supported assessment or E-assessment is a field of growing importance. preparing manual test is a difficult task to handle and a time consuming process for teachers, in which they have to prepare both fair and consistent exam for each class. Besides, even is the teacher can prepare a sufficient exam, it is difficult to prevent students from cheating and if teachers cannot prevent them from doing this injustice, it will occur again and again. With this new system,...
ABSTRACT Zobo and Kunu drinks are non-alcoholic beverage that is widely produced and consumed in Nigeria.The beverage may possess health risk when contaminated due to method of preparation. Zobo and Kunu drinks were purchased from different sellers in Olabisi Onabanjo University, Ago-Iwoye Ogun State. Physical and chemical analysis of the drinks were carried out, involving pour plate were also employed to isolate bacteria from these drinks. The microbial qualities were determined using pour p...

Abstract: Phytoremediation has been identified as an effective option for the clean-up of petroleum hydrocarbon contaminated soil. The aim of this study is to assess the potential of Vigna unguiculata L. Walp (cowpea) in the remediation of used motor oil contaminated soil. The germination and growth of cowpea on soil contaminated with 5% (w/w) of used motor oil was monitored for 28 days. One of the treatments received 15% (w/w) poultry manure seven days after pollution. Result of the phys...
ABSTRACT For schools to be effective, computer literacy should be demonstrated through computer availability as well as student’s awareness and usage of library related website. The research design is a descriptive survey which comprises a sample of 383 students randomly selected from a population of YABATECH students. The research instrument is a well-designed questionnaire for students. The statistical tools employed in to analyze the data are frequency and percentage distribution; t...
Abstract: This study was aimed at determining the antibacterial effect of the leaf extract of Buchholzia coriacea (Wonderful Kola) on nasal isolates. Nasal isolates were collected from one hundred students of the Delta State Polytechnic, Ogwash-uku, Delta State. The antimicrobial activity of the methanolic extract of the leaves was assessed against nasal isolated microorganisms (E.coli, Citrobacter species, Klebsiella species, and Proteus species) using the agar well diffusion method. Inh...
Abstract Polycyclic aromatic hydrocarbons, heavy metals and physiochemical parameters were measured in water samples from zaakpon community. The results shows that most of the parameters in water were within safe limits except turbidity, potassium and Phosphate while PAHs concentrations in water were below detection limit
The author proposes to build a unique and easy to use train ticketing system with QR code for my final year project using cloud infrastructure. The system allows users to register and as soon as they register an account with unique id is created in the system. User may book or buy tickets and fare is calculated according to station distance. The cloud server allows for handling a large number of users using efficient computing power. It allows for efficient and fast computing for ticket costs...
Abstract Weight loss and Density Functional Theory (DFT) methods were used to study the corrosion inhibition of 5-methyl-2H-imidazol-4-carboxaldehyde and 1H-Indole-3-carboxaldehyde on mild steel in acid medium. The values of thermodynamic parameters such as free energy of adsorption (ΔGºads), adsorption equilibrium constant (Kads), adsorption entropy (ΔSºads), adsorption enthalpy (ΔHºads) and activation energy (Ea) were calculated and discussed. The adsorption process on mild steel surf...
Radiation exposures from mining and mineral processing industries can lead to high incidence of disease conditions like nausea, lung cancer, sterility, fatigue, and diarrhoea among mine workers. The concentration of primodial radionuclides (238U, 232Th and 40K) in some selected mining sites in Nasarawa State, Nigeria, was examined in this study. Soil and rock samples from eight different mining sites were collected and analyzed for radionuclides activity concentration by gamma ray...
