The chemical substances were impregnated on the resin + ethyl cellulose blend coated cellulose strips of 8x3 cm²made of Whatman filter paper 42. The metals and salts (adsorbents) have been impregnated separately on cellulose strip. The dried melamine methylurea formaldehyde polymer resin was blended with ethyl cellulose powder (1:0.05) for higher porosity. The vacant forces of adsorbent develop interaction with gases, as they happen to be the polar and form coordination bond. Thereby weight gain was observed and confirmation was made with IR, SEM and XRF techniques. <br/> <br/>Page(s): 205-225 Sat, 26 Feb 2005 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/5032 Title: Studies on ignition of TPE based RDX propellants by laser impulse <br/> <br/>Authors: Sanghavi, R R; Sundaram, S G; Kulkarni, M W; Asthana, S N; Bohra, B M <br/> <br/>Abstract: Laser light exhibits specific characteristics in the energy transfer to high-energy materials (HEMs) leading to subsequent decomposition process. A set-up was established for laser ignition. Induction time is one of the critical parameters of the HEMs used for various applications. During this study, it was experimentally determined for TPE based RDX-propellants, which are potential candidates for low vulnerability ammunition. Laser beam from a solid state pulsed Nd-YAG operating at 1.06 mm wavelength was used as energy source. An interesting observation was, increase in ignition delay on incorporation of glycidyl azide prepolymer and decrease in ignition delay on addition of ballistic modifier. <br/> <br/>Page(s): 175-180 Sat, 26 Feb 2005 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/5031 Title: Application of nitrogen as preventive and controlling subsurface fire – Indian context <br/> <br/>Authors: Mohalik, N K; Singh, R V K; Pandey, J; Singh, V K <br/> <br/>Abstract: The application of liquid/gaseous nitrogen, which inhibits combustion for preventing, controlling and extinguishing mine fires, is now universally accepted for last 50 y. This paper presents the scientific relevance and selective criteria for use of N₂ in subsurface fire and reviews experiences of N₂use in Indian coalmines for more than 20 y. The different techniques of N₂ production, its advantages and disadvantages are described briefly. A case study of using N₂as a preventive material, in goaf area of working panels of blasting gallery (BG) method of mining is also highlighted. <br/> <br/>Page(s): 273-280 Sat, 26 Feb 2005 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/5030 Title: Decision support system for regional domestic energy planning <br/> <br/>Authors: Ramachandra, T V; Krishna, S Vamsee; Shruthi, B V <br/> <br/>Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="country-region"> Rural energy planning depends solely on the existing levels of energy consumption in domestic sector. In India, energy requirements for cooking and water heating depend predominantly on biomass fuels, which are often burnt in traditional stoves (efficiency < 10%), while kerosene and electricity are used for lighting. A sound environmental development of a region needs promotion of conservation activities among local communities and application of traditional environmentally sound technologies. Environmental research activities in recent years have generated large data on energy processes, mainly on commercial sources of energy such as, coal, oil, natural gas, and electricity are generally available, a lot of effort is still required to quantify traditional sources of energy. In this regard, Decision Support System (DSS) with relevant data help the decision makers to take appropriate timelier decisions and assist in the evaluation of reliability and the generation of alternatives. DSS incorporates simulation and optimization models with interactive graphics capabilities to encourage the acceptance of analyzing techniques in practice. This paper presents a conceptual framework for analyzing energy consumption at domestic sector via DSS. The framework is based on material flux, comparative analyses of village level domestic energy consumption patterns across various zones considering regional and seasonal variations. It also differentiates between household activities like cooking, water heating, and space heating which are the major end use activities. The system with a synergistic integration of software tools will assist decision makers in understanding the process status better and also aid in providing timelier decisions and efficient outputs. DSS is validated with the data pertaining to energy situation of Kolar district. Stratified random survey covering 2500 households distributed uniformly over the district shows that most households still use traditional stoves for cooking (97.9%) and water heating (98.3%). Energy analysis shows that the consumption ranges as follows: fuel wood for cooking, 0.69±0.34-1.42±0.27 kg/capita/d; electricity for lighting, 5.17±2.16-6.57±4.07 kWh/capita/month; kerosene for cooking, 0.44 ±0.16-1±0.76 l/capita/month; LPG for cooking, 0.18 ±0.05-1.03 ±1.35 kg/capita/month; and, biogas for lighting, 0.6 ±0.29-0.76 ±0.28 m³/capita/d. </smarttagtype></smarttagtype> <br/> <br/>Page(s): 163-174 Sat, 26 Feb 2005 22:58:59 GMT
