Mechanical Characterization of Earth-Based Composites Materials Reinforced with Treated Bamboo Fibres for Affordable Housing

Abstract This paper presents the characterization of laterite-cement-based matrix composites, reinforced with chemically modified bamboo fibers. Fiber extraction and chemical modification were first explored by soaking slabs of bamboos in NaOH solution (5 wt.% of NaOH in distilled water) for 14 days. Fiber characterization, as well as the flexural and compressive strength of reinforced composites, were carried out with MTS universal mechanical testing machine. Comparative results on the compr...

Recycling of Plastic Waste Material: Mechanical Properties and Implications for Road Construction

AbstractThe main purpose of the project is to convert polyethylenetetraphylate (PET), a known plastic waste material in Ghana, to wealth. Composite samples were produced by heating aggregates together with shredded PET plastic waste material, while bitumen was added to the plasticcoated aggregates. The composites produced were of 4.5 wt%, 9.0 wt%, 13.6 wt% and 18.0 wt% concentrations of PET. Mechanical and optical characterisation of the fabricated composite samples were studied for optimizat...

Fabrication of 3D Printed Scaffolds for Tissue Engineering: Understanding the Mechanical Stability, Degradation Mechanisms and Biocompatibility.

Abstract Diabetes mellitus, also known as diabetes has on major effect on its patients. This is the effect of impaired wound healing. Patients thus get minor wounds such as small cuts which become non-healing and are liable to get infected. Severe cases of such occasions lead to amputations. A solution to this problem is tissue regeneration with the help of scaffolds. These scaffolds are made of biopolymers and promote cell adhesion, regeneration and minimal diffusional constraints. Computer ...

DESIGN AND FABRICATION OF A SOLAR-POWERED ELECTRIC STOVE FOR RURAL AND URBAN COMMUNITIES OF GHANA

Abstract This report presents the optimisation of a ceramic-matrix composite (anthill sand and cement), reinforced with treated coir fibres for applications in the construction of a low costsolar powered cooking stove to solve the current trends in the depletion of forest spaces in Ghana due to excessive destruction as a result of using firewood for cooking by a higher percentage of rural communities. The reinforced coir fibres reduce undesirable traits in ceramics including, low fracture tou...

Performance of a Parallel Hybrid Electric vehicle with Liquefied Natural Gas

Abstract Fossil Fuels are currently classified as some of the leading producers of greenhouse gases which are major agents of Global warming. This study establishes the benefits Liquified Natural Gas (LNG) would have when used as a fuel in a hybrid-electric vehicle. The study establishes a Parallel-Hybrid vehicle model equipped with a control system to determine the mode of operation of the vehicle. Simulations using the vehicle models developed were performed in AVL Cruise. The results gener...

DESIGN OF A BIOMASS POWER PLANT FOR MAJOR COMMERCIAL CLUSTER IN IBADAN, NIGERIA

ABSTRACT The Nigerian Electricity Supply Industry is currently under reforms due to inadequate power supply to meet basic needs.

A model for tracking temperature variation in cold and hot metal working conditions during machining operations

ABSTRACT This paper presents a mathematical model that could assist in measuring, monitoring and controlling temperature variation in cold and 'red-hot" metal working conditions or machining. 

Comparative Analysis of Simulation Time in Nonlinear and Harmonically Excited Pendulum and Duffing Oscillators

ABSTRACT The motivation for the present study is derived from the fact that time management is an integral pan of good engineering practice. 

Energy-Exergy Analysis and Carbon Emission of Nigerian Cement Manufacturing Industry

ABSTRACT Two of the largest manufacturing plants in Nigeria named plant A and plant B were studied and the data collected from the 10year period 1995-2005 from them enabled an analysis of their energy consumption, energy cost per tone, efficiency of energy use from exergy analysis and carbon dioxide emission rate

VEHICLE SPEED CONTROL USING ROAD BUMPS

ABSTRACT Road bumps play a crucial role in enforcing speed limits, thereby preventing over speeding of vehicle.

THE CONSTRAINTS AND PROSPECTS OF SMALL SCALE BUSINESS ENTERPRISES IN NIGERIA

ABSTRACT Small businesses play a vital role in the economic development of any nation.

STRESS LOOP EFFECTS IN DUCTILE FAILURE OF MILD STEEL

ABSTRACT A simulation study of effect of stress on mild steel microstructure has revealed stress loop at areas of stress application which are believed to be the root cause of ductile failure morphology in ductile alloys under plane strain conditions.

SIMULATION AND OPTIMISATION OF A SOLAR-POWERED ADSORPTION ,REFRIGERATION MODULE

ABSTRACT Adsorption refrigeration technology has been intensively investigated in many countries of the world because of its potential for competing with conventional vapour compression refrigeration and its environmental friendliness.

REHABILITATION OF PUMPS: CASE STUDY OF UNIVERSAL PUMP SET

ABSTRACT Laboratory equipment  is meant to impart some modules of knowledge unto students of engineering and applied science.

PROSPECTS FOR SOFTWARE DEVELOPMENT FOR INDIGENOUS DESIGNS
