Enhancing concrete properties with the use of coconut (coir) fibers and admixture

AbstractIn countries where industrialization is on the rise there is a corresponding increase in wasteproduction resulting from industries which eventually upsetsthe environment and communityfor which they provide. While most of these waste generated are hazardous and should bemanaged, others could be put to appropriate use either directly or after been recycled. Mostagro-waste can be recycled and be used asraw materialsfor manufacturing various products.This research is designed to investiga...

STABILIZATION OF SILTY CLAY SOIL USING CEMENT AND SAW DUST ASH samson et al

ABSTRACT Soils containing large quantities of clay and silt are the most burdensome to the engineer. These soils exhibit marked changes in volume with changes in water content and consequently affect the function of any layer lain upon it due to its shrink and up heave behavior when used as a subgrade or a layer built of it. The test assesses the geotechnical characteristics of silty clay soil in order to increase the shear strength and decrease the compressibility of the soil, so t...

PRODUCTION OF BIOGAS USING COW DUND, GRASS CUTTINGS, PIG WASTE

ABSTRACTThis study comparatively analysed biogas production from three waste materials: Grass - Axonopus compressus, cow dung and pig waste slurry, with respect to the effects of carbon/nitrogen (C:N) ratio on biogas yield. A mixing ratio of 1:10 (one (1) part of substrate to ten (10) parts of water) was used. Nine 2L plastic digesters, were used for the study. Digestion was carried out in triplicates, 3 digesters for each substrate. The C:N ratios of the substrates were as follows:  Axonopu...

The impact of noise from a polythene nylon production and recycling factory

Creating a friendly workplace which is devoid of pollution is a top priority globally. This study assesses the impact of noise from a polythene nylon production and recycling factory. The HD600 Datalogging Sound Level Meter was used for the assessment of noise within the factory and at twenty-three sampling points outside the factory. A World Health Organization standard questionnaire was also administered to selected respondents within and outside the factory to obtain information on su...

Air pollution

The spread of pollutant in an area is partly a function of wood burning in local kitchens by the population of the area. This pollution generated through combustion of wood  fuels presents difficult environmental challenges to societies as it could degrade the environment and affect human health and quality of life. Wood burning emissions are major contributors to air pollution in rural areas as they contain harmful gases. The level of carbon monoxide in the air in two location in oleh town ...

Optimal Under-Frequency Load Curtailment via Continuous Load Control in a Single Area Power System Using Fuzzy Logic, PIDFuzzy and Neuro-Fuzzy (ANFIS) Controllers

Abstract —  In  situations  where maximum  load  demand  exceeds  power  generation  capacity,  frequency  would drop during  cases  of  overload;  and if  appropriate  under-frequency  load curtailment  scheme  is  not  put  in  place,  it  could cause permanent  turbine  damage or  affect  the expected  working  operation  of  electric equipment.  Various  existing works  on load  curtailment  in  power  systems  have been  done to  great  effe...

Future SCADA System for Smart Grid

ABSTRACTTraditional power grids are now transformed into Smart Grids (SGs) in order to solve the problems of energy wastage, energy control, uni-directional flow of information, growing energy demand, reliability, measurement and security. Smart grids increase the automation, coordination and connectivity between these electricity suppliers, electricity users and networks used in local distribution tasks and long distance transmission. Smart Grids offer bi-directional energy flow between elec...

Design and Construction of a Four Way Traffic Light Control

ABSTRACTA traffic light also known as a traffic signal,  stop light and go light, robot or semaphore is a signally device positioned at four (cross) junction, pedestrian crossing or other locations in other to indicate when it is safe to drive or walk using a universal color code ( and in precise sequence for those that are color blind).Traffic light system operate on a turning mechanism that changes the light after a given interval of 7-120 seconds depending on the traffic congestion on...

PHYSICOCHEMICAL PARAMETERS & LEVEL OF SOME TOXIC METALS IN STREET DUST

ABSTRACT This research study the concentration of certain toxic metals in street dust along road construction site and relate the finding to the standard control measure to determine the extent to which environmental uncontrolled process can pollute the environment. This study therefore investigate the Physicochemical parameters of street dust and concentration of three toxic metals; Nickel (Ni), Copper (Cu) and Cadmium (Cd) in Arakale – NEPA Road in Akure City of Ondo State. ...

Effect of Electromagnetic Treatment of Water on Growth, Germination and Yield of Maize Crop

The effect of magnetic treatment of water on the growth, yield and germination of maize seed has a positive impact in Agricultural crop production

Design of Next Generation Civil and Military Aircraft with Ultra-High Bypass Engine using Composites, Advanced Materials and Technology

AbstractIndirect combustion noise had not been attracting research in the past, but recent indication seems to prove that it could be a threat in the future if not addressed. Means of reducing this type of noise to a low decibel value was also included. Noise is due to the ingestion of distorted atmospheric turbulence, as the two set of blades rotate in different direction. Open rotor noise is higher since the rotors are fully exposed to oncoming turbulence and lack ducting or a nacelle to at...

Comparative Study On The Strength Of Lightweight Foamed Concrete Using Different Reagents (Lithofoam & Sodium Lauryl Sulphate)

ABSTRACTThis project presents the results of the investigation conducted on a lightweight foamed concrete using different reagents; Sodium Lauryl Sulphate (SLS) and Lithofoam, with a view to determining its potential as a construction material in Nigeria. The properties investigated on the foamed concrete having target density of 1800kg/m3 were: workability, bulk density and compressive strength. The foamed concretes produced using SLS were developed using a w/c ratio of 0.5 and a mix r...

Contactless Power Transfer System Using Inductive Coupling-based Wireless power transfer (WPT) Principle

Wireless power transfer (WPT) technologies have been widely used in many areas, e.g., the charging of electric toothbrush, mobile phones, and electric vehicles. This project introduces fundamental principles of three WPT technologies, i.e., inductive coupling-based WPT, magnetic resonant coupling-based WPT, and electromagnetic radiation-based WPT, together with discussions of their strengths and weaknesses. Several WPT applications are described. Open research challenges are then presented wi...
