To The Editor: To elucidate the mechanism of granulocyte damage during FL, studies have been reported of the interaction between nylon-wool fibers and isolated granulocytes suspended in protein free media,’2 in 5% plasma,2 or in 1% human serum albumin.3 In FL, however, heparinized whole blood is passed through a nylon-wool filter, resulting in plasma protein coating of the fibers within seconds...

Limiting the generation of polymers waste and maximizing their recyclability recovery have been main focus research industry in recent years. Recycling polyamides leads to loss mechanical thermal properties, therefore, order reuse recycled nylons, an enhancement properties is desired. Enhancing by addition functionalised graphene nanoparticles (GNPs) was goal this study. Recycled PA6/PA6,6 blen...

in this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. mechanical properties of micro and nano- composites, including tensile strength, elongation, and young’s modulus, before and after ageing, were determined and analyzed. for this purpose, micro- and nano-sized caco3 particles were used as fillers to prepare micro-composites (c...

Abstract This experimental work aims at evaluating the mechanical and failure behavior of adhesive-bonded single-lap joints made a thermoplastic composite 3D-printed via Fused Filament Fabrication technology. Carbon fiber was selected as reinforcement used in form both short continuous fibers embedded Nylon-6 matrix, forming composite's hybrid structure. An approach based on progressive improve...

It is presented an optical fiber sensing system projected to operate in the demanding conditions associated with coal waste piles in combustion. Distributed temperature measurement and spot gas sensing are requirements for such a system. A field prototype has been installed and is continuously gathering data, which will input a geological model of the coal waste piles in combustion aiming to un...

The study examined the problem of waste disposal and management in Ughelli. A field survey was undertaken to determine the types, volume, effects and methods of managing solid waste in the Ughelli. The volume of waste was measured at dumpsites in the four existing quarters and from household bins. Appropriate waste characterization methods were employed in classifying the waste into various com...

The final features of natural fiber composites (NFCs) depend on the integrated characteristics of their constituents. In the industry today, natural agro waste fibers are evaluated using a limited number of criteria. In this work, a combined multi-criteria evaluation stage technique (CMCEST) is introduced as a simple efficient systematic indicator to enhance evaluation of the available natural ...
