Physical Properties of Cookies Produced from Cassava – Groundnut-Corn Starch Blend- A Response Surface Analysis

ABSTRACT Cookie bars were produced from mixtures of cassava and groundnut flours with cornstarch as binder. Box-Behnken response surface design for k=3 was used to study the effects of experimental variables for cassava flour (25- 75%), groundnut flour (25-75%) and corn starch (5-15%). Effects of the experimental variables on physical properties of the cookie bars were assessed. Experimental variables had significant effect on the thickness and spread factor of the cookie bars.Keywo...

QUALITY, SENSORY AND STORAGE ATTRIBUTES OF CHEESE PRODUCED FROM COWMILK SUPPLEMENTED WITH TIGERNUT AND COCONUT MILK

ABSTRACTCheese is a concentrated dairy product produced by acid or rennet curdling of milk, stirring and heating the curd, draining off the whey, collecting and pressing the curd. In this study, Cheese was made from cow milk supplemented with tigernut milk and coconut milk in the percentage ratio of 25:25:50; 25:50:25; 50:25:25; 75:25:0; 75:0:25% cow- tigernut milk-coconut milk (v/v). The unsupplemented cow milk cheese was used as control. The quality, shelf life and sensory attributes of the...

CHARACTERISATION OF MICROWAVED AND OVEN DRIED AERIAL YAM (Dioscorea bulbifera) STARCH

ABSTRACTNative Starch was extracted from Aerial yam (Dioscorea bulbifera). The starch extracted wasdried using oven (at 300C for 24 hours) and microwaved for (30, 45, 60 seconds). Starch obtainedusing different drying methods and conditions were analysed for their physicochemical, functionalproperties and pasting characteristics. Results obtained showed that amylose, amylopectin, colour,pH, bulk density, swelling power, least gelation capacity, oil absorption capacity, water absorptioncapacit...

DELINEATION OF SALTWATER INTRUSION ZONE IN PARTS EASTERN OF NIGER DELTA USING RESISTIVITY AND GEOCHEMICAL DATA

ABSTRACT Detailed hydro -geophysical and hydro-geochemical studies were carried out in part of the Niger Delta Basin Nigeria. The objectives were to map and provide evidences that the coastal aquifers in the study area have been intruded by saltwater and to establish analytical/empirical relationships between resistivity and geochemical parameters. Twenty three vertical electrical sounding (VES) data employing the Schlumberger electrode configurati...

Data Mining Model for Decision Making in Telecommunication Industry: Case Study of Emerging Market Telecommunication Services (EMTs)

ABSTRACT This work present a data mining model for decision making in telecommunication industry. Nowadays, most sales and marketing organization, around the world face escalating competition which is forcing them not only to aggressively market special pricing programs aimed at retaining existing customers and attracting new ones but also for effective management and allocation of resources, goods and services. In this project work, several litera...

A Model of Tertiary Institutions Resource Management Platform Using Cloud Computing (TIRMP)

ABSTRACT In Cloud Computing, users connect to the ’Cloud’, appearing as a single entity as opposed to multiple servers. This work seeks to solve resource managerial problems ranging from server maintenance cost, risk of loss of data, internal security issues, and availability of data for proper decision making. This work presents to tertiary institutions a model for designing a scalable and cost effective platform for insti...

Controllability Results for Non-Linear Neutral Functional Differential Equations

ABSTRACT In this work, necessary and sufficient conditions are investigated and proved for the controllability of nonlinear functional neutral differential equations. The existence, form, and uniqueness of the optimal control of the linear systems are also derived. Global uniform asymptotic stability for nonlinear infinite neutral differential systems are investigated and proved and ultimately, the Shaefers’ fixed point theor...

Enhanced Admission Enquiries System Using Chatbot Technology

ABSTRACT In this research work, a chatbot that will act as a virtual admission officer and make possible student – officer interaction is designed. A knowledge database (KDB) and pattern matching algorithm is used. The algorithm searches through the set of data to find a potential answer to the user’s enquiry and then replies the user or provides a relevant web link if the user is not satisfied with the answer. This reduces the burden on the hea...

Antimicrobial Activities of Oil Extracts of Piper Guineense and Xylopia Aethiopica on Some Microbial Pathogens of Food

ABSTRACT Oils extracted from the fruits of two Africa spices- Piper guineense and Xylopia aethiopica were evaluated for their antimicrobial activities using Escherichia coli, Salmonella sp, Aspergillus sp, Bacillus cereus, Penicillum commune and Rhizopus stolonifer as test isolates. Well-in-agar, disc diffusion and dilution susceptibility testing methods were used to assay for their antimicrobial properties. For the bacterial isolates the antimicro...

Novel Quantitative Analysis of Gas Dynamics Equations using Physics Informed Neural Network (PINN) Raj Rashmi and Kojiro Suzuki (Univ. of Tokyo)

The discovery of governing equations using the Physics Informed Neural Network (PINN) based on spatial-temporal data is revolutionizing the field of statistical physics. This study combines neural network technology with deterministic model equations and molecular simulation to find an appropriate description of stochastic phenomena. Conventional stochastic solvers rely on molecular interactions and enforce basic conservation laws on a microscopic level. Data-driven algorithms like PINN, ...

Comparative study on the Effect of Temperature and Concentration on Waste Agricultural Cellulose Biomass Degradation

Bioconversion of agricultural waste products to produce value-added food products like simple sugar; fuels and chemicals offers potential economic, environmental and strategic advantages over traditional fossil-based products. A comparative study on the effect of temperature and concentration on waste cellulose biomass degradation to glucose was studied at temperature range of 80 – 1300C and concentration range of 2, 4, 4.5, 5.0, 5.5 and 6Mol/dm3 for a period of 48hours. The ...

Comparative Of Production And Proximate Analysis Of Cake, Bread And Cookies Using Plantain Flour

Background of the studyThere is increased advocacy on the consumption of functional foods by World human nutrition due to different health problems related with food consumption such as diabetes and coronary heart diseases (WHO/FAO, 2003). Food professional/industries might face challenges of producing food products containing functional ingredients in order to meet the nutritional requirements of individuals with health challenges. This is because of the effect of added sugar and lipids...
