An adaptive neuro-fuzzy interface system model for traffic classification and noise prediction(Soft Computing)
(A Sharma, R Vijay, GL Bodhe, LG Malik,,,,Year : 2018)
|
In present study, two adaptive neuro-fuzzy models have been developed for traffic classification and noise prediction, respectively. The traffic classification model (ANFIS-TC) classifies extracted sound features of different categories of vehicles based on their acoustic signatures. The model also compute total number of vehicles passes through a particular sampling point. The results have been used for the estimation of the equivalent traffic flow (QE). The noise prediction model (ANFIS-TNP) has three inputs, namely equivalent traffic flow (QE), equivalent vehicle speed (SE) and honking. The equivalent traffic flow (QE) is the output of ANFIS-TC model, while equivalent vehicle speed (SE) and honking are computed from observed averaged speed of different categories of vehicles and number of recorded horns blow per minute. The model assumes that the distance between sound level meter and road centerline is fixed for particular sampling point. The performance of both the models has been validated by field observations. The results show that traffic classification is 100% accurate, while correlation coefficients between observed and predicted traffic noise range from 0.75 to 0.96. Both the models are validated with random samples of data, and it is observed that both the models are generalized and could be employed for traffic classification and traffic noise prediction in small urban heterogeneous traffic environment for noise pollution assessment and control.

Study of temporal variations in aerosol optical depth over central India(I. J. Environmental Protection)
(A. B. Chelani
,5(1),,25-31,Year : 2015)
|
Monthly aerosol optical depth (AOD) data over central India during 2001-2010 obtained from Moderate Resolution Imaging Spectroradiometer are analyzed for trend and periodicity. For this purpose, spectral analysis and linear trend analysis are performed. High AOD during monsoon followed by summer months are observed. Spatial analysis did not show any significant spatial variations in AOD levels. Spectral analysis suggested two dominant periods; 12 months and 6 months consistent with the annual and seasonal patterns. Trend analysis showed an insignificant trend at all the locations. Decadal change in AOD is the highest in Nagpur, which is an urban agglomeration station. Less developed and nonurban areas, however show decreasing or insignificant trend in AOD levels. Correlation with change in population over the last decade at different locations showed significant positive relationship with percentage change in AOD levels suggesting the effect of urban agglomeration on AOD in central India

Wetland Treatment (HSSP) of wastewater from a Milk-Processing Unit using Bambusa vulgaris, Typha latifolia and Cyperus rotundus.(Journal of Environmental Sciences & Engineering)
(Mangesh Inarkar,52 (1),,23-26,Year : 2010)
|
Studies were conducted in soil-less horizontal sub-surface flow wetland (HSSF) embedded with graded gravels using Golden bamboo, Bambusa vulgaris (a non-wetland species), Typha latifolia and Cyperus rotundus (wetland species) for the treatment of wastewater from a milk processing unit. The wastewater was treated with a dilution ratio of 3:1. Removal efficiencies of BOD and COD were studied at one, two and three days hydraulic retention time (HRT). At one day HRT, the removal efficiency (%) of these parameters was lower in comparison to when the wastewater was subjected to two and three days HRT. The increase in removal efficiency with increase in HRT was marginal when it was increased from 2 days to 3 days. The percentage removal of COD and BOD at two days retention time followed the order: Golden bamboo (93, 88) > Cyperus rotundus (91, 90) > Typha latifolia (85, 87).

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.

Causes and Remedies For Filamentous Foaming In Activated Sludge Treatment Plant.(Global NEST Journal)
(Khairnar K, Pal P, Paunikar W,Vol 16,,,p 762-772,Year : 2014)
|
"This paper reviews the problem of foaming associated with the activated sludge process and its control using various physical, chemical and biological methods. Activated sludge process is widely used for treatment of every type of wastewater like industrial, domestic and municipal wastewater. This process is driven by a complex microbial population, among which some mycolic acid containing bacteria leads to the stable foam formation which ultimately results in poor efficiency of the plants and leading to major environmental, operational, and health problems. A number of researches provide the evidences of foaming in wastewater treatment plants and its control using physical, chemical and biological methods. Current approaches for controlling foam includes operational adjustments, additional structures, controlling dissolved oxygen levels, water sprays, steam application, polymer addition, chlorination and a novel and ecofriendly approach that is treatment of filamentous bacteria with the specific phages. A detailed study of all methods is presented and collectively described in this review paper for a better understanding of the foam controlling strategies. "

Recycling E-Waste for Sustainable Management of Natural Resources. In: Monitoring and Assessment of Natural Resources for Sustainable Management(National Conference MANRSM-2017, School of Environmental Earth Sciences, North Maharashtra University, Jalgaon)
(,,,,Year : 2017)
|
Electronic waste (E-waste) which consists of old, end-of life, discarded electrical and electronic equipment’s (EEE), is the most rapidly growing MSW stream worldwide. The toxic and hazardous materials present in it can lead to severe environmental and occupational hazards, if not handled properly. However, presence of significant quantity of valuable recoverable material makes it a potential secondary resource for metal extraction. Composition of E-waste is complex with 38% ferrous material, 28% non-ferrous material, 19% plastic, 4% glass, 11% other (wood, rubber, ceramic, etc.). Although the precious materials are only 1% by weight, it accounts to nearly 80% of the total intrinsic value. Around $ 21 billion of Au and Ag are used in various EEE per annum.Along with precious metals it also contains various rare earth metals such as Platinum, Gallium, Indium, Lithium, etc. Primary metal extraction from mining has significant negative environmental impact due to substantial natural resources consumed and low recovery efficiency; comparatively extraction from E-waste is 50 times greater which is much more economical with lesser ecological foot printand the energy savings are considerable: aluminium 95%, copper 85%, iron and steel 74%, plastics 80%. This is the reason why E-waste recycling which is also called as “Urban Mining” can facilitate in sustainable management and conservation of rapidly depleting natural resources.

(Nishant Dafale, Uttam Semwal, Piyush Agarwal, Pradip Sharma, G. N. Singh ,51,,18-26,Year : 2015)
|
The aim of this study was to develop and validate a simple, sensitive, precise and cost-effective one-level agar diffusion (5+1) bioassay for estimation of potency and bioactivity of Levofloxacin in pharmaceutical preparation which has not yet been reported in any pharmacopoeia. Among 16 microbial strains, Bacillus pumilus ATCC-14884 was selected as the most significant strain against Levofloxacin. Bioassay was optimized by investigating several factors such as buffer pH, inoculums concentration and reference standard concentration. Identification of Levofloxacin in commercial sample Levoflox tablet was done by FTIR spectroscopy. Mean potency recovery value for Levofloxacin in Levoflox tablet was estimated as 100.90%. A validated bioassay method showed linearity (r2=0.988), precision (Interday RSD=1.05%, between analyst RSD=1.02%) and accuracy (101.23%, RSD=0.72%). Bioassay was correlated with HPLC using same sample and estimated potencies were 100.90% and 99.37%, respectively. Results show that bioassay is a suitable method for estimation of potency and bioactivity of Levofloxacin pharmaceutical preparations.

"Titania Gold Composite: Effect of Illumination on Size of Gold Nanoparticles with Consequent Implication on Photocatalytic Water Splitting"(Russian Journal of Physical Chemistry)
(Girivyankatesh Hippargi, Pratap Reddy Maddigapu, Nitin Labhsetwar, and Sadhana Rayalu, Vol. 11, No. 6,p. 1002–1011. ,Year : 2016)
|
"This work deals with the study of photodeposition (PD) of gold nanoparticles (AuNPs) on TiO2 by using different illumination sources, Medium pressure Mercury lamp (ML), Solar Simulator equipped with AM 1.5 (SL) and Tungsten lamp (WL). Different particle size of AuNPs on TiO2 were obtained by photodeposition method under different illumination sources, which clearly proves the influence of light source on the synthesis of Au–TiO2. The plasmonic activity of Au–TiO2 photocatalyst for water splitting reaction was observed to be strongly influenced by the particle size of Au as well as illumination source. Amongst the three different illumination sources used, smallest particle size for AuNP–TiO2 were observed under ML followed by SL and WL, as revealed by TEM analysis. Different illumination sources were also investigated to evaluate the activity of Au–TiO2 samples thus prepared under different illumination conditions. The order of hydrogen evolution rate (HER) observed for Au–TiO2 with different source of illuminations is ML > SL > WL. The highest HER of 1709 μmol/h was observed for Au–TiO2, which was synthesized and evaluated under ML irradiation. This may be explained on the basis of reduced catalytic activity and photothermal effect of Au nanoparticles with increasing particle size."
