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.

Prediction and Examination of Seasonal Variation of Ozone with Meteorological parameter Through Artificial Neural Network(Urban Climate)
(Navneet Kumar, Anirban Middey and Padma S. Rao,20,,148-167,Year : 2017)
|
The present study focused on seasonal relations and predictions of the ozone (O3) coupled with NO2 and meteorology. Monitoring of ozone concentration throughout year shows an increasing trend during summer and a decreasing trend in the winter season. A comparison between three types of ANN; multilayer perceptron trained (MLP) with back-propagation, radial basis functions (RBF) and generalized regression neural network (GRNN) for short prediction of ozone are conclusively demonstrated. The model results are validated with observations from next monsoon. Based on the model's performance, the MLP back propagation model gives the best correlation between observed and predicted ozone concentrations than other models. Performance assessment parameters considered in the study also indicates that MLP is the best-fit model for prediction of ozone concentration throughout the year

Megacities in Asia rank high in air pollution at the global scale. In many cities, ambient concentrations of fine particulate matter (PM2.5) have been exceeding both the WHO interim targets as well as respective national air quality standards. This paper presents a systems analytical perspective on management options that could efficiently improve air quality at the urban scale, having Delhi as a case study. We employ the newly developed GAINS-City policy analysis framework, consisting of a bottom up emission calculation combined with atmospheric chemistry-transport calculation, to derive innovative insights into the current sources of pollution and their impacts on ambient PM2.5, both from emissions of primary PM as well as precursors of secondary inorganic and organic aerosols. We outline the likely future development of these sources, quantify the related ambient PM2.5 concentrations and health impacts, and explore potential policy interventions that could effectively reduce environmental pollution and resulting health impacts in the coming years. The analysis demonstrates that effective improvement of Delhi's air quality requires collaboration with neighboring States and must involve sources that are less relevant in industrialized countries. At the same time, many of the policy interventions will have multiple co-benefits on development targets in Delhi and its neighboring States. Outcomes of this study, as well as the modelling tools used herein, are applicable to other urban areas and fast growing metropolitan zones in the emerging Asian regions

Particulate and Gases Pollution Control during Ldling Condition of Vehicles at Traffic Intersections: A Case Study for Nagpur City(Earth Sciences)
(Navneet Kumar, Rajendra Prasad Poluru, Padma S. Rao, Mayuri Shrirang, Ashish P. Patil,,,,Year : 2017)
|
Traffic intersections are major contributors for built-up of emissions of air pollutants like PM10, PM2.5, SO2 and NOx from automobiles. The study has been carried out for Nagpur, third largest city in the Indian state of Maharashtra. Emissions of PM10, PM2.5, SO2 and NOx quantified for one month, and control studies from motor vehicles during idling condition at a traffic signal were carried out at three foremost traffic signals of the city. The selected traffic intersections are Law College Square, Medical Square, and Shankar Nagar square. In this study selected parameters Air Metrics measured PM10 PM2.5 SO2 and NOx and followed by titrimetric gaseous impinger system and control of the same assessed by bench scale air pollution control (BAPC) system. Reduction percentages from the BAPC system were obtained as 57.68 & 47.65 for PM10 and PM2.5 respectively whereas for SO2, 70.55 and for NOx, 54.53 obtained

Study of local and Regional influence of PM2.5 Concentration during Odd-even Rule in Delhi using Causual Analysis(Aerosol & Air Quality Research)
(A. B. Chelani
,175,,1190-1203,Year : 2017)
|
PM2.5 concentration observed during odd-even rule in Delhi is analysed for assessing its effectiveness in curbing the levels. The local and regional influence is analysed by using similarity and causality analysis. Causality analysis is usually carried out by using nonlinear dynamical technique which predicts one variable using another. In this study a simple approach is presented based on nearest neighbour method. It is observed that PM2.5 in Delhi has regional influence in addition to local sources. Although the effectiveness of odd-even rule is not observed in curbing the PM2.5 levels, it is suggested that extended implementation of the rule may provide more insight to the impact. Similarity analysis suggested that PM2.5 concentrations in Delhi have somewhat similar temporal behaviour with neighbouring locations in the southeast (SE) and west (W)-southwest (SW) sector. The control policies in Delhi need to be adopted keeping in mind the local and regional influences on PM2.5 levels in the area

Isolation and enrichment of bacteriophages by membrane filtration immobilization technique.(Current protocol in cell Biology)
(Ghugare, G. S.,Nimkande, V
,e41. ,,,Year : 2017)
|
The method described here enables rapid bacteriophage isolation and enrichment of host-specific bacteriophages from an environmental sample. This is achieved by using a simple 0.45-µm Milli pore membrane where a specific host is immobilized on the membrane and a sample suspected of containing bacteriophages is exposed to the immobilized cells with the help of a membrane ltration unit. This filtration step facilitates host-specific interaction of bacteriophages with the host and maximization of this interaction using a classic membrane filtration method.Under the effect of vacuum from a vacuum pump, a filter assembly provides a chance for every bacteriophage in the sample to interact with the specific host on the membrane filter. Our technique allows retaining specific bacteriophages on the membrane along with its host cells via adsorption; these adsorbed bacteriophages (along with their hosts) on a filter disc are then enriched in regular nutritive broth, tryptone soya broth (TSB), by incubation. With help of a plaque assay method, host-specific phages of various bacterial species can be isolated, segregated, and enriched

"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."

Nanocellulose for biosorption of chlorpyrifos from water: chemometric optimization, kinetics and equilibrium(Cellulose )
(Pareshkumar G. Moradeeya , Madhava Anil Kumar , Ravikumar B. Thorat, Manali Rathod , Yasmin Khambhaty ,,,1319–1332,Year : 2017)
|
|
The study explores the biosorption potential of nanocellulose (NC) to remove an insecticide, chlorpyrifos (CP), from aqueous solutions using the batch method. Biosorption kinetics were very fast and reached equilibrium in 60 min, and the experimental kinetic data had fit well with the pseudo-second-order model. Film diffusion was the rate-limiting step for the biosorption of CP onto crystalline nanocellulose (CNC). The equilibrium sorption was well described by the Sips and Langmuir isotherm models. The values of maximum sorption capacities (7.237–5.017 mg/g for the Sips and 12.325–7.247 mg/g for the Langmuir model) decreased with an increase in temperature from 288 to 308 K, signifying biosorption of CP is an exothermic process. Based on the central composite design (CCD), two-factor interaction (2FI) and quadratic models, the correlation between the effects of variable parameters on the CP biosorption onto NC was evaluated. The chemometric analyses suggested that 1.5 g/l NC required 20 min to biosorb 5 mg/l CP to yield an efficiency of 99.3%. Overall, the results demonstrated that NCs can be a promising biosorbent for the removal of pesticides from aqueous streams.

Integrative genomic analysis identifies ancestry-related expression quantitative trait loci on DNA polymerase β and supports the association of genetic ancestry with survival disparities in head and neck squamous cell carcinoma(Cancer)
(Meganathan, P. R., Devarajan, K., Blackman, E., Gibbs, D., Luce, D., Deloumeaux, J., Duflo, S., Liu, J.C., Mehra, R., Kulathinal, R.J., Ragin, C.C,,,849-860,Year : 2017)

BACKGROUND:
African Americans with head and neck squamous cell carcinoma (HNSCC) have a lower survival rate than whites. This study investigated the functional importance of ancestry-informative single-nucleotide polymorphisms (SNPs) in HNSCC and also examined the effect of functionally important genetic elements on racial disparities in HNSCC survival.
METHODS:
Ancestry-informative SNPs, RNA sequencing, methylation, and copy number variation data for 316 oral cavity and laryngeal cancer patients were analyzed across 178 DNA repair genes. The results of expression quantitative trait locus (eQTL) analyses were also replicated with a Gene Expression Omnibus (GEO) data set. The effects of eQTLs on overall survival (OS) and disease-free survival (DFS) were evaluated. RESULTS: Five ancestry-related SNPs were identified as cis-eQTLs in the DNA polymerase (POLB) gene (false discovery rate [FDR]0.01). The homozygous/heterozygous genotypes containing the African allele showed higher POLB expression than the homozygous white allele genotype (P<.001). A replication study using a GEO data set validated all 5 eQTLs and also showed a statistically significant difference in POLB expression based on genetic ancestry (P=.002). An association was observed between these eQTLs and OS (P<.037; FDR<0.0363) as well as DFS (P=.018 to .0629; FDR 0.079) for oral cavity and laryngeal cancer patients treated with platinum-based chemotherapy and/or radiotherapy. Genotypes containing the African allele were associated with poor OS/DFS in comparison with homozygous genotypes harboring the white allele.
CONCLUSIONS:
Analyses show that ancestry-related alleles could act as eQTLs in HNSCC and support the association of ancestry-related genetic factors with survival disparities in patients diagnosed with oral cavity and laryngeal cancer. Cancer 2017;123:849-60. © 2016 American Cancer Society.

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.
