Environmental concerns are being intensified in composite manufacturing ventures, using agricultural fillers as strategic materials to improve environmentally-conscious performance. In this investigation, which is the first ...

In this attempt, which is a second part of discussions on tapped density optimisationfor four agricultural wastes (particles of coconut, periwinkle, palm kernel and egg), performance analysis for comparative basis is made. ...

According to the United Nation Development Programme, access to modern low-cost energy systems in developing countries is important in the realization of the globally agreed developmental goals, as well as the Millennium ...

The majority of the street lighting systems in Nigeria are predominantly composed of inefficient lighting fixtures powered either by the grid or diesel generators. Due to the epileptic nature of the grid and the fluctuations ...

The study presents the dependence of the effective moisture diffusivity of yam slices on temperature. A laboratory-scale Refractance WindowTM dryer was used in the investigation. Moisture content measurements of 4.5 mm ...

Three-dimensional numerical studies were carried out to investigate forced convection heat transfer and fluid flow in a solid substrate cooled using different types of micro heat sinks. The objective of this study is to ...

In this work, mathematical models were developed to simulate the thermal behaviour of a cutting tool insert in three-dimensional dry machining. Models to determine the temperature rise at the shear plane and tool insert ...

This paper evaluates some basic functional properties of iron-millscale-reinforced ceramic matrix composites (CMCs) as potential material for automobiles and aircraft brake pads’ application. The particulate CMCs were ...

Thermal characteristics of processed macro-fibres from five agricultural wastes have been studied. Cellulosic fibres for composite applications are extracted from groundnut shell, coconut shell, rice husk, palm bunch and ...

Power inverters operate under dynamic loads; the varying loads cause thermal expansion and contraction, which stress the internal boundaries between the material layers in the semiconductor. Eventually, the stress wears ...

In this study, thermal performance analysis of a natural convection porous fin with temperature dependent thermal conductivity and internal heat generation is carried out using Galerkin’s method of weighted residual. The ...

This article reports a successful removal of CaCO3 from snail and periwinkle shells for the purpose of producing high quality chitin for possible application as bio-fillers in bone fixation materials. Experiment was designed ...

This study investigates the effects of coconut shell (CS) and snail shell (SS) volume fractions on the thermal and mechanical properties of Unsaturated Polyester Resin (UPR) composite. Varying percentages of the fillers ...

Crude oils are generally very complex chemical systems consisting predominantly of hundreds to thousands of hydrocarbon compounds from simple lowmolecular-weight paraffins to high-molecular-weight waxes. At low temperatures ...

The need for water level monitoring has increased over the years. Water level monitoring is among other things useful for oil and gas exploration and exploitation activities, and construction of ports and harbour works. ...

In oil and gas production system, slugging is frequently encountered when gas-liquid mixtures are transported through a common pipeline-riser system. This phenomenon usually manifests in significant fluctuation of flow and ...

The conditions influencing the phenomenon of heat affected zone (HAZ) cracking during tungsten inert gas (TIG) welding of a gamma-prime (γ’) precipitation strengthened nickel-base superalloy, IN 738, is discussed here. ...

In this study, microhardness variation as well as macro and micro structural examination of the heat affected zone (HAZ) of a girth welded API 5L X46 pipeline material were conducted as a means of tracking local brittle ...
