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...

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...

The development of transportation plays an important role in the development of nation. With flexible pavements being widely used in India, steps must be taken to increase the life of the bituminous pavements. Flexible pavements are often plagued with problems of cracking and rutting due to repeated traffic loads. Hence one needs to address these problems in order to improve the performance of ...

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 ...

BACKGROUND Production of medicinal plants in controlled environments, particularly hydroponic technology, provides opportunities for high quality biomass accumulation and optimizes production of secondary metabolites. Applying special watering regimes in combination with efficient soil draining is an encouraging new tool for the production of pharmaceutical relevant plants. The purpose of this ...

Cultivation of strawberries in greenhouses and polytunnels is increasing, new sustainable growing media are needed to replace peat coconut coir. This study investigated the effect wood fiber compost as on hydroponically cultivated strawberries. Two experiments were conducted, where everbearing cultivar ‘Murano’ was grown mixtures (Experiment 1) seasonal flowering ‘Malling Centenary’ 2). Additio...

Ground vibrations can be caused by various sources such as traffic, construction activities, and industrial machinery. These propagate through the ground into adjacent structures or environment. Predicting controlling are essential in fields, transportation, construction, activities. Regulations guidelines have been developed many countries to manage impact of on people structures. Open In-fill...

india has large resources of natural fibres such as banana, khus, sisal, korai grass,talipot, palm leaf, coconut, pineapple, screwpine, golden grass, jute and sabaiamong others. in the past, trade of the village folk depended on harvesting fibresgrown in their villages. natural fibers have recently gaining attraction of researchersdue to their low cost eco-friendly and biodegradability characte...
