Recently, there is increase in the use of natural fiber reinforcement polymer composites due to its low production cost, ease fabrication and enhanced strength. In this study, effect NaOH treatment on tensile properties coconut fibre for polyester resin transtibial prosthetic socket was investigated. The fibres were extracted using hand pulling water retting method; used mercerize carried out 5...

Environmental concerns have resulted in the search for environmentally friendly natural oils for use as mosquito larvacide. Methylated coconut oil has been found to be toxic to mosquito larvae. However, the use of methylated coconut oil is limited by resource constraints in rural communities in Papua New Guinea and other Pacific Island countries where coconut oil is produced by traditional meth...

Coconut stand out as the foremost amongst the palms that human kind has discovered for is multifarious uses to sustain and support life. In recent years emphasis is focused on product diversification, by products utilization and development of value added coconut products to improve the coconut economy. Coconut jam is a traditional high sugar coconut food product, commonly consumed as desert, b...

The electric field of a charged particle passing through or near an optical fiber induces a transient charges and currents in the fibrer medium (1; 2). These charges and current radiates electromagnetic waves, both outside the fiber (free light) and inside (guided light). This chapter is devoted to the guided light, which will be referred to as PIGL, for Particle Induced Guided Light. If the fi...

In the present study, a theoretical model was used to examine factors affecting the filtration characteristics of filters used for respiratory protection. This work was designed to support the particulate filter test requirements established in 1996. The major operating parameters examined in this work include face velocity, fiber diameter, packing density, filter thickness, and fiber charge de...

In this paper, we present a methodology for simulating pressure drop and collection efficiency of a filter medium during instantaneous particle loading using the ANSYS–Fluent CFD code, enhanced with inhouse subroutines. The simulations are comprised of a numerical solution of the Stokes equations for obtaining the air flow field, and Lagrangian particle tracking, for determining the particle co...
