Adsorption equilibrium data could be well fitted by Freundlich model. Adsorption of pyridine on adsorbent was physical adsorption and lower temperature was favorable to exothermic physisorption process. Adsorption capacities calculated by pseudo-second-order rate model were close to the values actually measured at lower temperatures. <br/> <br/>Page(s): 73-76 Tue, 29 Dec 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/7046 Title: A new technology of marble slurry waste utilisation in roads <br/> <br/>Authors: Misra, A K; Mathur, Renu; Rao, Y V; Singh, A P; Goel, Pankaj <br/> <br/>Abstract: Marble slurry dust (MSD, a waste of marble industry, finds bulk utilization potential in roads. This study indicates that besides embankment construction with this waste, 20-30% of soil can be replaced by MSD for sub-grade preparation. Technology has been validated by taking full scale trials in the field. <br/> <br/>Page(s): 67-72 Tue, 29 Dec 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/7045 Title: Performance and emission evaluation of a diesel engine fueled with methyl ester of neem oil and filtered neem oil <br/> <br/>Authors: Ragit, S S; Mohapatra, S K; Kundu, K <br/> <br/>Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> Neem oil methyl ester (NOME) was tested in 4-stroke single cylinder water cooled diesel engine. Brake thermal efficiency of NO100 has been found 63.11% higher than that of diesel at part load whereas it reduces 11.2% with diesel fuel at full load. As NOME is concerned, HC is reduced at all load condition, whereas smoke is also reduced at full load condition. NOx has reduced slightly at all load condition, and EGT showed increasing trend at full load condition. Other emissions (CO, CO₂ and O₂) do not contribute bad effect on engine. Thus, NOME can be a substitute for diesel fuel in diesel engine. </smarttagtype></smarttagtype> <br/> <br/>Page(s): 62-66 Tue, 29 Dec 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/7044 Title: FPGA-based PWM control of hybrid single-phase active power filter for harmonic compensation <br/> <br/>Authors: Rahim, N A; Islam, Z; Raihan, S R S <br/> <br/>Abstract: This paper presents implementation of sinusoidal pulse-width-modulation (PWM) for a single-phase hybrid power filter. A series active power filter and a shunt passive filter were combined to suppress harmonic current and isolate harmonic between source and load. For active filter control, PWM was developed in an ALTERA® FLEX 10K Field Programmable Gate Array (FPGA), and modulation index was selected by calculating DC bus voltage of active filter through a digital Proportional-Integral- Derivative (PID) controller. System has been found capable of compensating load current and voltage harmonic within specification of EMC standard IEC 61000-3-2. <br/> <br/>Page(s): 55-61 Tue, 29 Dec 2009 22:58:59 GMT
