The objective of work was focused to investigate microstructure of polyurethane foam and cyclic crushing strength of its sandwich structure which made of sisal / coir / bamboo / glass fabrics as reinforcement with polyester resin to form composites skin. The tested sandwich panels were constructed four type of FRP faceplates made of sisal / coir / bamboo / glass fiber reinforcements impregnated...

Rose plants (Rosa x hybrida L. CV. Kardinal, grafted on Natal Brier) were grown in UC mix and in coconut coir. Water release curves and hydraulic conductivity of the media were measured. Water tensions in the media were maintained within a predetermined narrow range by tension-actuated irrigation, using high-flow electronic tensiometers. Transpiration rate of plants sitting on load cells was me...

Physical, mechanical and dynamic properties of composites produced from coconut fibres using pure water sachet (LDPE) as matrix were evaluated in this study order to assess its suitability for use particleboards. The LDPE (waste sachets) coir/fibre collected, shredded milled into pellets. Five compositions with fibre loading 5, 10, 15, 20, 25%, corresponding 95, 90, 85, 80 75%. A sixth sample 1...

Cellulose nanofibers were isolated from coconut coir fibers by chemical treatment using alkaline, mineral acids and inorganic salts, followed by mechanical treatment and disintegration methods like sonication, cryo crushing and dissolution. The size and morphology of cellulose nanofibers were investigated by using the Field Emission Scanning Electron Microscope (FESEM). The width of synthesized...

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...

The coconut mite, Aceria guerreronis Keifer, has emerged as a common menace to most of the coconut plantations in India. After its first upsurge in Kerala at the end of the 1990 ́s, the mite has spread to many states in southern and northern India, causing considerable damage. Coconut provides one third of the agricultural income in the regions in which it is grown and more than 10 million peopl...
