Application of microwave synthesized Ag-Rh nanoparticles in cyclohexane dehydrogenation for enhanced H2 delivery(International journal of hydrogen energy)
(Jayshri V Pande, Ankush B Bindwal, Yogesh B Pakade, Rajesh B Biniwale,43:,,7411-7423,Year : 2018)

The catalytic dehydrogenation of liquid organic hydrides (LOH) is a promising route to deliver H2 for various mobile and stationary applications. However, an efficient and low-cost dehydrogenation catalyst, as an alternative to Pt, is a key for the success of LOH-based H2 supply. In a quest for such catalysts, we synthesized stable Ag-Rh bimetallic nanoparticles (BNP) supported on activated carbon cloth (ACC) and Y2O3 using the microwave-assisted polyol technique. The performance of these catalysts during dehydrogenation of LOH viz., cyclohexane, was evaluated at 300 ?C using an advanced spray-pulse reactor system. The Ag:Rh ratio was optimized to maximize the cyclohexane conversion and H2 evolution. The effect of Ag:Rh ratio, catalyst support, and synthesis method was investigated, too. The most stable H2 evolution performance was exhibited by microwave-synthesized 1:4 Ag-Rh/Y2O3 catalyst with the cyclohexane conversion, dehydrogenation rate and H2 evolution rate of 35.8%, 17.2 mmol/gMet/min and 400 mmol/gMet/min, respectively. Finally, the performance of catalysts used in this study was compared with the Pt-based catalysts.

Thunderstorms are well-known severe weather phenomena of the Gangetic West Bengal (GWB) region of India. The objective of the present study is to identify the ranges of Max_Z parameters of Doppler Weather Radar (DWR) associated with precipitating clouds that eventually grow into thunderstorms and to obtain a model to assess the predictability of thunderstorm and non-thunderstorm events with maximum possible accuracy during the pre-monsoon season (April–May) over the metropolis Kolkata (22.6°N; 88.4°E) enclosed within GWB (20–26°N, 85–91°E), India. The DWR imageries are analyzed to identify the stages of thunderstorm development. The survival of the fittest principle of genetic algorithm (GA) is implemented to find a suitable combination of the DWR Max_Z parameters; the reflectivity, distance of the first detected echo from Kolkata where the DWR is installed and the echo top height for the genesis of thunderstorms. The problem is posed as an optimization problem and the values of the parameters are converted into binary strings. The result reveals that the echoes with reflectivity between 44 and 48 dBZ at a distance of 250–300 km from Kolkata with echo top height between 13 and 15 km have the maximum possibility to grow into a thunderstorm. The artificial neural network (ANN) model is developed with the values of the Max_Z parameters optimized by GA as the inputs. The target of the ANN model is to forecast the type of the echo cells leading either to thunderstorm or non-thunderstorm events. The result further reveals that the ANN model with three hidden layers and one node in each layer is the most suitable model for estimating the likelihood of thunderstorm/non-thunderstorm events with mean absolute error (MAE) of 0.71/2.81. The result of the study is validated with the observation of India Meteorological Department.

An impact of sewage pumping failure on coastal water quality of Mumbai, India. (Indian Journal of Geo-marine Sciences)
(Trupti Mardikar,Vol. 46(8),,1528-1538,Year : 2017)
|
A model was conceptualised to emulate the behaviour of coastal water during high and low tides and the impact of the pump failure in present and projected future scenarios was estimated on it. The model was validated before being used for failure scenario simulation. The study indicates that potential adverse effects on water quality are imminent in case of sewage pumping station failure and warrants better planning and management in terms of diversionary and evacuation routes and preparedness plans.

Development of Irrigation Potential in Malikhedi Sericulture Farm of Ujjain District, M.P(" Technologies for Sustainable Rural Development having Potential of socio-economic upliftment")
(Raghuvanshi Ram, J. P. Shukla, C. Padmakar and R. N. Yadava,377-381,,,Year : 2014)
|
"sericulture, particularly mulberry sericulture has attained industry status by involving the landless poor women living in rural india. This activity has been in practice in traditional rearing areas throughout the state of Madhya Pradesh. The existing irrigation potential of the farm has been utilised upto the optimal extent, still there exists a huge gap between supply and demand. On an average it has been estimated that the present irrigation potential should be doubled to meet the crop water requirement. In this regard, an attempt has been made in the present study to understand the aquifer geometry and the development of irrigation potential of mulberry plantation in one of the sericulture farms of Ujjain district using extensive field visits through geological mapping and geo-electrical surveys. After detailed study, the present farm status could be brought to the good category from moderate irrigation potential farm."

Heavy metal concentrations in suspended particulate matter (SPM) were investigated for their distribution and source in the atmosphere of coastal industrial town, Mithapur, Gujarat, India. SPM, at 10 locations covering three seasons, were trapped on glass fibre filters using high volume samplers and quantification of metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) was done using Atomic Absorption Spectrometry employing HNO3 based wet digestion. Results show relatively low concentrations of SPM (211.3 to 375.2 ?g/m3) compared to National Ambient Air Quality Standard (NAAQS), specified By Central Pollution Control Board (CPCB, India), however, they were 2–3 times higher as compared to reference site. Among the heavy metals Cr, Mn and Pb levels were low, while Ni and Cd found to be exceeding the USEPA standards. The metal levels were also compared with those reported for other rural, coastal, industrial and urban parts around the world. Enrichment Factor analysis indicated that Cd, Zn, Cu, Pb and Ni were highly enriched relative to their crustal ratios (to Fe) and correspond to substantial contribution of anthropogenic source of these metals. The source identification was carried out by principal component analysis by applying a Varimax Rotated Component Matrix.

Isolation of bacteriophages from air using vacuum filtration technique: an improved and novel method.(Journal of applied microbiology)
(Magare B, Nair A,
,Volume 123,, Issue 4 ,Page 896–902,Year : 2017)
|
"AIM: Development of a simple and economical air sampler for isolation and enrichment of bacteriophages from air samples. METHODS AND RESULTS: A vacuum filtration unit with simple modifications was used for isolation of bacteriophages from air sampled in the lavatory. Air was sampled at the rate of 62 l min-1 by bubbling into Mcllvaine buffer for 30 min, which was used as bacteriophage solution for enrichment and plaque assessment against individual hosts. Alternatively, the aforementioned phage solution was enriched using a host consortium before plaque assessment. Phages were isolated in the range of 1-12 PFU per ml by the first method, whereas enrichment with host consortium gave phages around 10- to 1000-folds higher in number. Combining with established enrichment method, an improvement of about 10 times in phage isolation efficiency was attained. CONCLUSIONS: The method is very useful for studying the natural bacteriophages of air, requiring only a basic microbiological laboratory setup making it simple and economical. SIGNIFICANCE AND IMPACT OF THE STUDY: This study brings out a simple, economical air sampler for assessing air bacteriophages that can be employed by any microbial laboratory. Although various methods are available for studying bacteriophages in water and soil, very limited are available for air. To the best of our knowledge, the method developed in this study is unique in its design and concept for studying bacteriophages in air. The sampler is sterilizable by autoclaving and maintains a healthy rate of airflow provided by conventional vacuum pumps. The use of a nonspecific 'trapping solution' allows for the qualitative and quantitative study of air bacteriophages."

Waste Management in India: E-waste recycling & Bio-methanation -Case studies(Journal of Solid Waste Technology & Management )
(Roychoudhuri, Reshma, Debnath, Biswajit, Jayakumar, Sandhya, Maloo, Ajay ,Vol. 42,1,748-759,Year : 2016)

Waste management system in India at present is taking a significant change. Majority of the problems are associated with the management of municipal solid waste, E-waste and CD waste. Though the MSW rules 2000 were implemented long back, the rules pertaining to e-waste management has been implemented in 2012. All the rules related to waste management are undergoing revision at present which is expected to lead to a sea change in effectiveness in addition to some new rules in the country. The traditional system of landfilling or dumping is now being replaced by different waste treatment processes. This paper deals with two case studies, of a E-waste recycling plant and a Bio-methanation plant in India, which were studied by a visiting team from the recently held IconSWM 2015 in Bangalore. It has been observed that both the plants are running effectively to curb the disposal of wastes into dumping grounds as well as recover materials and energy. This study will present the materials and energy recovery processes adopted in both the plants and proposed methodologies to make the systems more effective. This study will also highlight the general and specific issues and challenges related to E-waste recycling and biomethanation plants and elaborate on how to overcome those. The results of the study will help the researchers and implementers for further actions.

Introduction: In open-cast mines, noise pollution has become a serious concern due to the extreme use of heavy earth moving machinery (HEMM). Materials and Methods: This study is focused to measure and assess the effects of the existing noise levels of major operational mines in the Keonjhar, Sundergadh, and Mayurbhanj districts of Odisha, India. The transportation noise levels were also considered in this study, which was predicted using the modified Federal Highway Administration (FHWA) model. Result and Discussion: It was observed that noise induced by HEMM such as rock breakers, jackhammers, dumpers, and excavators, blasting noise in the mining terrain, as well as associated transportation noise became a major source of annoyance to the habitants living in proximity to the mines. The noise produced by mechanized mining operations was observed between 74.3 and 115.2 dB(A), and its impact on residential areas was observed between 49.4 and 58.9 dB(A). In addition, the noise contour maps of sound level dispersion were demonstrated with the utilization of advanced noise prediction software tools for better understanding. Conclusion: Finally, the predicted values at residential zone and traffic noise are correlated with observed values, and the coefficient of determination, R2, was calculated to be 0.6891 and 0.5967, respectively.
