EFFECT OF DRYING METHODS AND PRETREATMENTS ON FUNCTIONAL PROPERTIES OF SWEET POTATO FLOUR Ogunlakin, G. O., *Olajire, A. S., Ajiboye, T. S. and Fagbohun, M. A. Department of Food Engineering, Ladoke Akintola University of Technology, Ogbomoso, Oyo State Nigeria.

The deployment of solar energy system is necessary to meet the energy demands of the rural areas in Nigeria. The investment for the system components is capital intensive and therefore, a techno- economic model which can be used to rapidly design the system is imperative. This paper presents the development of a novel and unique solar PV energy system model (SPVSM) which can be used to accurately size PV system components.

ABSTRACT Zeolite Y was developed from Bambu clay using two steps of preparation: seed gel and feed gel methods for production of the zeolite. Bambu clay was used as a source of aluminium hydroxide and sodium silicate after undergoing splitting techniques. The clay, meta-kaolin, Synthesis Zeolite Y (SZY), and Commercial Zeolite Y (CZY) were characterised using X-ray Fluorescence (XRF), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), Scanning Electron Microscope (SEM), and Fourier Transform Infrared (FTIR) spectroscopy.

The Paper determined the capacity and level of operational performance of Ojoo Roundabout and New Garage Roundabout traffic intersections in Ibadan, Oyo State, Nigeria. These Roundabouts were gridlock intersections, where roundabout was introduced to control traffic flow and reduce congestion. As traffic volume increases in Ibadan metropolis, the unsignalised road intersections having roundabouts as control measures also exhibit traffic congestion especially at peak periods. This study analysed the traffic operation and evaluated the capacity for the two selected roundabouts.

The dearth of effective and indigenous manpower is a critical challenge facing the solar power industry in Nigeria. Several solar power training conducted lack well-structured hands-on practical scheme due to lack of appropriate equipment for the trainees. Therefore, this research work reports the design and development of a Hybrid Solar Power Trainer (HSPT) equipment using locally sourced materials. Double Diamond model was adopted where related research works were reviewed and then analyzed to have a well-defined goal leading to the design, development and implementation processes. The constructed HSPT equipment is detachable for ease of mobility. It also has the capability of simulating a typical household electrical wiring that is powered either by the grid supply/generator/solar power system or in their hybrid configuration for the purpose of teaching practical. The developed trainer was tested both on

In order to reduce the carbon footing of the cement industry in concrete production, this research investigated the possibility of using a ternary blended cement composed of ordinary portland cement, palm kernel shell ash and coconut shell ash in concrete. The experimental procedure involves employing a mix ratio of 1:2:4 at constant water to binder ratio of 0.63 in casting ternary concrete cubes with varying OPC: PS: CS ash ratios of 100:0:0, 97.5:1.25:1.25, 95:2.5:2.5, 92.5:3.25:3.25, 90:5:5 and 85:7.5:7.5 under research laboratory conditions. Test results show that the workability of the fresh ternary blended concrete diminishes with increase in percent substituted pozzolanic ash using the slump test. At day 7, all the pozzolana containing

A process model for the operation of rotary kiln in the cement production process was developed using Aspen Plus to study the effect of alternative fuels from used tyre, municipal waste (MSW) and sugarcane bagasse on clinker quality, emissions and thermal stability by introducing 5%, 10%, 15%, 20%, 25% and 30% of the alternative fuel mix with coal. The three fuels increased the Lime Saturated Factor (LSF) compared to 100% coal, but the observed values were within acceptable limits. Sugarcane bagasse had the best silica ratio (SR between 2.49458 to 2.49405), with Used Tyre and MSW having a low silica ratio below 1.6. However, the low SRs were complemented by their alumina ratios (ARS). Used Tyre and Sugarcane bagasse can maintain the

The aim of this study is to represent coexistence of harmonics in the power system through an extensive comparison among the different electric bulbs. The Harmonics in the electrical distribution system are the by-products of modern electronics. They are especially prevalent where there are large numbers of nonlinear loads such as compact fluorescent lamp, light emitting diode lamp, personal computers, printers, copiers, hospital equipment, fluorescent lighting and adjustable speed drives. Harmonics do no useful contributions; they degrade the power quality and efficiency in a commercial building or industrial facility. Most people do not comprehend those harmonics have been around for more than 100 years ago.

Globally, for energy sufficiency, incentives are put in place to drive more sustainable alternative energy sources that are renewable and eco- friendly. Biodiesels production from varied feedstocks and application in engines are encouraged due to the fuel higher lubrication quality, excellent combustion properties and low greenhouse gas emission. Khaya senegalensis seeds, a nonedible, readily available feedstock was used to extract its bio-oil. This research explored the seeds oil feasibility as biodiesel, so the crude oil was pretreated by esterification and trans-esterified to biodiesel. The specific objectives of this research were to establish the specific chemical characteristics - compositions, the essential components, the percentiles, and the quantitative transformation of desired components from the crude oil to the biodiesel as processed from Khaya senegalensis seeds.

Corrosion inhibition behaviour of metallic and semiconductor of Zinc Oxide Nanoparticles ZnONPs synthesized through biological means has been extensively reported. This work focuses on the synthesis of zinc oxide nanoparticles from cassava leaf (CL-ZnONPs) and has investigated its efficiency as corrosion inhibitor on mild steel in 1M HCl. The optical and structural properties of the resulting zinc oxide nanoparticles were studied using; UV-visible spectroscopy, Tauc's plot and Fourier transform Infrared spectroscopy (FTIR). The UV-Vis spectra of the zinc oxide nanoparticles showed typical absorption peaks around 371nm due to its large excitation binding energy at room temperature.

COREN mix design method for Nigeria and ACI method are both based on the basic principles and empirical relations, developed after substantial experiments of locally available materials. However, some minor differences are seen in the quantities of the material used for mix proportion, which includes the cement, aggregate (fine and coarse) and water content which attributes to the variation in strength of concrete. In ACI method, the quantities of fine aggregates were calculated, while the reverse is the case in COREN mix design method. The results indicate that the COREN method of mix design requires higher cement content than ACI method, and the water/cement ratio is higher in ACI method compare to COREN mix method. Although, the coarse aggregate content in COREN mix method is higher than the ACI mix method, from correlation and deviation between design and actual strength, it shows that COREN mix method is reliable and its meet the 25Mpa strength requirements than the ACI mix method.
