Item Terrestrial chemical spill information system through remote sensing, GIS and V.B. 6.0(2008) Dwarakish, G.S.; Angel, J.S.; Srinikethan, G.; Natesan, U.India has made remarkable progress in creating a modern and diversified industrial base, since its independence. Most of the refineries, petrochemical and fertilizer industries are located in the coastal zone and catered by 12 major ports along the 7500 km length of Indian coastline. Since, transportation of crude oil and POL products from ports to refineries are mostly by pipelines, rail/road, besides some quantity by barge/ships along the coast, there will be chances of oil spill/leakage. Managing these events before and during their occurrence is imperative to the protection of people and natural resources. The present study was carried out with a view to develop Terrestrial Chemical Spill Information System [TCSIS], using Remote Sensing [RS], GIS and VB 6.0., for the Mangalore coastal zone industrial area of Dakshina Kannada district, Karnataka state, along West Coast of India. The study area lies between 74°45′00″ to 74°52′30″E longitude and 12°52′30″ to 13°00′00″N latitude. The database of TCSIS consists of both conventional data and RS data, and analysed using ERDAS Imagine 9.0 and ArcGIS 8.3 software. Different thematic maps prepared include LU/LC map, drainage map, road and pipeline network map, slope map, Digital Elevation Model, relative risk maps and pipeline route for the transportation of hazardous chemicals from port to refinery. The TCSIS module developed using RS, GIS and V.B. 6.0, characterizes the ability of a spilled chemical to immediately impact human health, natural resources, and incorporates these into an overall measure of terrestrial chemical risk and aids in planning, preventing and responding to a terrestrial chemical spill. © 2008 SPIE.Item Extraction and characterisation of cellulose microfibrils from pongamia pinnata seed shell(International Committee on Composite Materials M.Wisnom@bristol.ac.uk, 2015) Manjula, P.; Srinikethan, G.; Shetty K, K.Biodiesel is a renewable resource of energy and has gained its importance in India due to soaring oil price and largely enhanced environmental awareness. Biodiesel and other biofuels are produced from agricultural plant and plant products. Pongamia Pinnata seeds have been identified as a superior and more sustainable source of biodiesel. The process generates large amount of unused Pongamia Pinnata seed shell. The present paper reports isolation of cellulose microfibrils from Pongamia Pinnata seed shell using chlorination and alkaline extraction process. The morphology of the cellulose microfibrils was investigated by Scanning Electron Microscopy. The cellulose microfibrils had diameter in the range of 0.8-2.6 μm. The crystallinity index obtained from X-ray diffraction and spectrums from Fourier transform infrared and Nuclear magnetic resonance spectroscopy for seed shell and extracted cellulose microfibrils, showed that the chemical treatments removed most of the hemicellulose and lignin from the seed shell fibers. The thermal stability of the fibers was analysed using thermogravimetric analysis, which demonstrated that thermal stability was enhanced noticeably for cellulose microfibrils. This work provides a new approach for more effective utilisation of Pongamia Pinnata seed shell to examine their potential use as reinforcement fibres in biocomposites. © 2015 International Committee on Composite Materials.
