The objective of the study is to develop GIS based noise simulation software for heterogeneous traffic conditions in metropolitan cities. In the present study traffic noise simulation software has been developed for sound level calculation. The software covers the following five input variables i.e., noise sources (point and mobile), vehicle speed, distance, honking and noise attenuation while noise Leq is the output of the software. The software is implemented for traffic noise level prediction at eight selected locations of Nagpur city. The field data is collected for a period of 15-minutes during the morning and evening rush hours. The correlation coefficient between measured and predicted noise Leq found to be 0.84. Results s

Friedel–Crafts green alkylation of xylenes with tert-butanol over mesoporous superacid UDCaT-5 (Chemical Engineering Research and Design)
(G. D. Yadav and S. B. Kamble,909:,,1322–1334, Year: 2012)

Friedel–Crafts green alkylation of xylenes with tert-butanol was investigated in the presence of mesoporous superacidic catalysts named as UDCaT-4, UDCaT-5 and UDCaT-6. The catalysts are modified versions of zirconia showing high catalytic activity, stability and reusability. The catalytic activity is in the order: UDCaT-5 (most active) > UDCaT-6 > UDCaT-4 > sulfated zirconia (least active). Synergistic effect of very high sulfur content present (9% (w/w) S) and preservation of tetragonal phase in UDCaT-5, in comparison with sulfated zirconia (4% (w/w) S), were responsible for higher catalytic activity. The performance of UDCaT-5 in alkylation of xylenes was studied with tert-butanol with reference to selectivity and stability. Alkylation of m-xylene over UDCaT-5 gives 96% conversion of tert-butanol with 82% selectivity towards 5-tert-butyl-m-xylene (5-TBMX) under optimum reaction conditions. The formation of products is correlated with the acidity of the catalyst. The reactions were conducted in liquid phase at relatively low reaction temperatures (130–160 °C). A systematic investigation of the effects of various operating parameters was done to describe the reaction pathway. The reaction was carried out without any solvent in order to make the process cleaner and greener. An overall second order kinetic equation was used to fit the experimental data, under the assumption that both xylene and tert-butanol are weakly adsorbed. An independent study of dehydration of tert-butanol (TBA) was also done. Alkylation of o-xylene and p-xylene with tert-butanol was also studied. The overall process is green and clean.

Atom efficient Friedel–Crafts acylation of toluene with propionic anhydride over solid mesoporous superacid UDCaT-5 (Applied Catalysis A: General)
(G. D. Yadav and S. B. Kamble , 433–434,,265-274, Year: 2012)

Friedel–Crafts acylation is ubiquitous in industry and is typically carried out by using more than stoichiometric quantities of homogeneous catalysts. This creates pollution. In this work, acylation of toluene was studied in liquid phase with propionic anhydride with a variety of solid superacids to produce 4?-methylpropiophenone (4?-MPP). The solid superacids were modified versions of zirconia, namely, UDCaT-4, UDCaT-5 and UDCaT-6 developed in our laboratory; amongst which UDCaT-5 was the most active, selective and robust catalyst. The effects of various reaction parameters on the rate of reaction and selectivity were investigated to deduce the intrinsic kinetics of the reaction. The reaction is free from any external mass transfer as well as intraparticle diffusion limitations and is intrinsically kinetically controlled. The acylation conditions were: temperature 180 °C, toluene to propionic anhydride molar ratio 5:1, catalyst loading 0.06 g cm?3, speed of agitation 1000 rpm, under autogenous pressure in a stainless steel autoclave reactor. Propionic acid generated in situ also reacts sequentially with toluene to give 4?-MPP. A conversion of 62% of priopionic anyhydride is obtained after 3 h, with 100% mono-acylated product containing 67% 4?-MPP. Water is the only co-product of the overall reaction. A suitable kinetic model was developed. The reactions were carried out without using any solvent in order to make the process cleaner and greener.

Chemical Speciation and Source Assignment of Particulate (PM10) Phase Molecular Markers in Mumbai. ( Aerosol and Air Quality Research)
(Mihir Herlekar, Abba Elizabeth Joseph,Vol. 12,,1247-1260, Year: 2012)

Particulate matter (PM10) has emerged as the single most important pollutant across Indian cities, as its levels exceed the regulated standards at most places. PM10 was collected and analyzed at seven sites representing different land use patterns in Mumbai during 2007-08 for organic carbon (OC) and elemental carbon (EC). OC was further speciated for organic markers, which are useful for identifying sources. Average PAH concentration ranged from 47.84 ± 14.07 to 247.70 ± 163.19 ng/m^3. n-alkanes concentration varied from 157.20 ± 35.28 to 759.13 ± 451.65 ng/m^3. Hopanes and steranes showed the highest concentrations of 94.14 ± 28.66 and 32.64 ± 11.79 ng/m^3 and lowest concentrations of 7.81 ± 2.00 ng/m^3 and 2.83 ± 0.73 ng/m^3, respectively. The values for levoglucosan varied from 0.69 ± 0.46 to 3.23 ± 2.07 ?g/m^3. The percentage contribution of the sum of the concentrations of these compounds to the total organic carbon varied from 1.7-5.1%. The sources contributing to particulate PAHs were identified using diagnostic ratios. Indicators like the Carbon Preference Index (CPI), Cmax and Plant Wax Number (%WNA) were used to identify the relative contributions to n-alkanes from anthropogenic and biogenic emissions. The source apportionment results and also the concentration trends for these molecular markers indicate that anthropogenic sources, especially vehicular exhaust, wood combustion and coal combustion, are mainly responsible for the organic fraction of particulate matter in Mumbai city. The sources identified qualitatively in this work can help in selecting the appropriate source profiles for estimating the quantitative contribution of these sources.

Methane emission potential and increased efficiency of a phytoremediation system bioaugmented with bacillus firmus xjsl 1-10 (International Journal of Phytoremdiation )
(Prachi A. Nimkar, Niranjan Kolekar,Vol.14(9):,,845-53, Year: 2012)

Horizontal subsurface flow constructed wetland mesocosms (HSSCW) designed to treat municipal waste water were bioaugmented with Bacillus firmus XJSL 1-10. The efficiencies of the three HSSCW mesocosms (non-vegetated HSSCW, Schoenoplectus validus HSSCW and Bambusa vulgaris HSSCW) were assessed. Bioaugmentation not only enhanced the efficiency of the phytoremediation system but also reduced methane emission from an average of 51.3 mg/m2/d to 21.6 mg/m2/d in Schoenoplectus validus HSSCW and from an average of 1708 mg/m2/d to 1473 mg/m2/d in Bambusa vulgaris HSSCW. Each of the three types of bioaugmented HSSCWs showed higher purification efficiency with respect to the removal of BOD and NH4-N than the non-bioaugmented HSSCWs. The performance enhancement was most significant in bioaugmented Schoenoplectus validus HSSCW mesocosm with 48.8 and 44.8% lower BOD, and NH4-N, respectively than the non-bioaugmented HSSCW.
