Processing of coir, which is the fibre obtained from the husk of the coconut, is a dusty procedure; 779 workers in two coir processing factories in Sri Lanka were examined clincally and radiographically for evidence of respiratory disease. Respiratory symptoms were present in 20 (2-6%) of them, which is no higher than in the general population. Respiratory disease such as asthma, chronic bronch...

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 ...

This research work developed and evaluated the mechanical properties of coconut fibre reinforced low density polyethylene (LPDE) composite material. The effect loading on properties: tensile, flexural, impact material have been investigated. Also carried out was water absorptivity Sample categories were prepared by varying contents weight at 0%, 10%, 20%, 30%. aim is to reduce excessive waste d...

Abstract The research region, Kallipatti, is surrounded by coconut farms, coir pith companies, and other businesses, people report that water has become their primary concern in the last three years. Skin eye allergies, as well lung throat infections, have been on rise. Coir degrades slowly can be found soil for long periods of time. tenacious accumulates environment, generating hillocks pollut...

We consider the task of dimensionality reduction for regression (DRR) informed by realvalued multivariate labels. The problem is often treated as a regression task where the goal is to find a low dimensional representation of the input data that preserves the statistical correlation with the targets. Recently, Covariance Operator Inverse Regression (COIR) was proposed as an effective solution t...

The purpose of this study was to develop substrates with little or no peat by combining coir-based growing media municipal compost and/or acacia biochar, two locally produced renewable resources, and assess their effects on lettuce seedling emergence growth, as well content in photosynthetic pigments total phenols. Two experiments were carried out, the first six mixes using biochar blended perl...

Though data-parallelism addresses a wide variety of problems in scientiic computing, this model in inadequate for general adaptive applications. Coir is our object-oriented thread-based model for data and task parallelism 25, 22, 24]. In this paper we brieey discuss the Coir objects-thread objects for control-parallelism and groups of thread objects, called ropes, for data-parallelism. Using an...

The structure of the isolated milled "wood" lignin from coconut coir has been characterized using different analytical methods, including Py-GC/MS, 2D NMR, DFRC, and thioacidolysis. The analyses demonstrated that it is a p-hydroxyphenyl-guaiacyl-syringyl (H-G-S) lignin, with a predominance of G units (S/G ratio 0.23) and considerable amounts of associated p-hydroxybenzoates. Two-dimensional NMR...

Aspergillus niger was used for cellulase production in submerged (SmF) and solid state fermentation (SSF). The maximum production of cellulase was obtained after 72 h of incubation in SSF and 96 h in Smf. The CMCase and FPase activities recorded in SSF were 8.89 and 3.56 U per g of dry mycelial bran (DBM), respectively. Where as in Smf the CMase & FPase activities were found to be 3.29 and 2.3 ...

The objective of this work was to develop an environmental friendly method for the effective utilization of coir fibre by adopting steam pre-treatment. The retting of the coconut bunch makes strong environmental problems which can be avoided by this method. Chemical characterization of the fibre during each processing stages confirmed the increase of cellulose content from raw (40%) to final st...
