Original injection timing of engine was 14° before top dead center (BTDC), and tests were conducted at advanced three different injection timings (17°, 20°,and 23°) by changing thickness of copper shim. Experiments were carried out at a constant injection pressure (2 bar) with varying injection flow rates of both producer gas and air at different engine speeds and loads. Advancing injection timing in as uper charged engine showed that diesel fuel displacement and brake thermal efficiency increased, with a significant reduction in carbon monoxide emission and specific energy consumption compared with original injection timing of premixed producer gas diesel dual fuel. <br/> <br/>Page(s): 220-224 Sat, 26 Feb 2011 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/11093 Title: Treatment of textile effluent by fly ash and reusing of colour adsorbed fly ash <br/> <br/>Authors: Chandrasekaran, P; Malathy, R <br/> <br/>Abstract: In this study, fly ash from thermal power plant was used as adsorbent for dye effluent emitted from textile processing industries. Sludge [colour adsorbed fly ash (CAF)] from packed column was used to replace cement in different proportions inconcrete. CAF concrete was not found equal to strength of conventional concrete but it was above the standard level and comparable. Durability test gave satisfactory results. <br/> <br/>Page(s): 235-239 Sat, 26 Feb 2011 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/11092 Title: Manufacturing rigid board by packaging waste containing aluminum and polyethylene <br/> <br/>Authors: Hidalgo, M <br/> <br/>Abstract: This study presents feasibility of using recycled low density polyethylene (LDPE) and aluminum of Tetra Pak to manufacture composite rigid board using a hot press. Compounds of LDPE / Al were significantly affected by the effect of compaction pressure during processing, especially in tensile strength and water absorption. Composite presents low water absorption, and acceptable tensile strength. <br/> <br/>Page(s): 232-234 Sat, 26 Feb 2011 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/11091 Title: Evaluation of radon exhalation rate from granite stone <br/> <br/>Authors: Nassiri, P; Ebrahimi, H; Shalkouhi, P Jafari <br/> <br/>Abstract: This study evaluates radon exhalation rate from 10 different granite stones, used for building construction in Iran.Radon exhalation rate ranged from non-detectable to 0.6 Bq m^-2 h^-1. Six samples had exhalation rate above detectable level. Asignificant statistical relationship between radon exhalation rate with ²²⁶Ra and ²³²Th indicated that ²²⁶Ra and ²³²Th wereresponsible for radon exhalation from granite stones. <br/> <br/>Page(s): 230-231 Sat, 26 Feb 2011 22:58:59 GMT
