The decision-making trial and evaluation laboratory (DEMATEL) technique is then used to discover the interrelationships between the barriers, which are then prioritised, based on three criteria (time, cost and relative importance) using complex proportional assessment (COPRAS) and multi-objective optimisation method by ratio analysis (MOORA). The Delphi method is used to obtain and analyse data from 10 petroleum experts who work at various petroleum facilities in India.FindingsThe findings provide practical insights for management and accident data analysts to use ML tech...

Environmental problems such as air pollution, water pollution and excessive consumption of natural resources are some of the formidable challenges faced by the communities globally. Application of nanotechnology is receiving more attention on environmental protection and is being applied in the areas of water treatment, wastewater treatment, groundwater remediation, soil remediation and waste management, etc. The volume of nanomaterials and nanoproducts has been anticipated to grow dramatically in the near future and the effective management of nano-waste is of great concern. "This paper reviews the application of nanomaterials for addressing environmental problems." It also highlights the challenges and priorities for responsible management of nano-waste. From the literature analysis, it can be inferred th...

Both were estimated using two separate computer programs; written in C language based on the eleven water quality parameters such as; pH, DO, BOD5, TDS, TSS, Cl-, NO3--N, SO42-, total hardness (THARD), total alkalinity (T-alkalinity) and total coliform (T-coliform). The WQI gives information about spatial and seasonal variations of pollution load and to classify river water into five classes (C1-C5) i.e. Excellent, Acceptable, Slightly Polluted, Polluted and Heavily Polluted respectively for drinking purposes. Whereas, SI gives an idea about whether quality of water is increasing or decreasing at same point during subsequent monitoring. This approach was used to classify water quality of Damodar river basin, India.

This paper demonstrates the reliability of the use of multi-criteria decision-making (MCDM) framework for the purpose of selecting the best MSW treatment and disposal alternatives. In this paper, a modified fuzzy Delphi-AHP-TOPSIS methodology is developed for the selection of the most appropriate MSW treatment and disposal technology. The study provides a systematic three-stage methodology towards technology selection. In the first stage, experts' opinions were sought to select the relevant criteria and the fuzzy Delphi Method (FDM) was used to obtain the critical factors for the evaluation of alternatives. In the second stage, the criteria weights and their importance degree were calculated by using AHP. Finally, the TOPSIS technique was used for ranking the alternatives to determine the most appropriate option. The study identifies a minimal relevant set ...

Providing an answer to this question investigating PEB has implications for planners and policymakers. The currents study attempts to identify and analyse the drivers that contribute to PEB significantly. To achieve this, an in-depth literature review and qualitative analysis were carried out. A questionnaire was developed to measure the PEB construct and its determinants. Next, the reliability of the questionnaire was assessed followed by Pearson’s correlational analysis. Results indicate that PEB comprises of nine dimensions viz., behavioural intention, attitude, personal moral norms, subjective norms, situational factors, perceived behavioural control, community concern, internal attribution and perceived consequences. The study results provide significant insights to help more people act in pro-environmental ways. From the theoretical perspective, the study resul...

Solution to this research question investigating PEB has significant implications for researchers, strategic planners and public policymakers. Multidisciplinary research seems necessary to answer this complex question identifying variables that influence PEB at the individual level. In the light of recent work on environmental paradigms, the currents study attempts to explore and identify the relevant factors that contribute to PEB significantly. To achieve the stated objective, an in-depth literature review and qualitative analysis were carried out. A questionnaire was developed to measure the PEB construct and its determinants. Next, the reliability of the questionnaire was assessed using pilot study. Following this, exploratory factor analysis was conducted to identify the major determinants. The validation of constructs using exploratory factor an...

In the analysis, FDCs were drawn for (i) 1 day, moving-day averages such as 3-, 7-, 30-, 60-day using daily discharge data of each sampling sites for the complete 30 years period-of-record 1981-2010 and (ii) 7-day mean 1-, 2-, 5-, 10-, 20-, 50- and 100-year return period from same data sets. Annual FDCs (AFDCs) were also constructed for each calendar year of 30 record period and discharge values were extracted at every 5% probability of exceedance for stochastic evaluation, then plotted for calculating annual minimum discharge on Weilbull probability paper were found to be usually straight line for each sampling sites except Tilaya site that enables confidence intervals and return periods to be associated with the FDC. The results indicate that for high probabili...
