Abstract	The study aimed to provide quantitative data on air pollution on people living in an industrial area of middle India. The twenty-four monitoring of nitrogen dioxide concentrations, sulfur dioxide, PM2.5 and PM10 was used to investigate people's exposure and health effects in the surrounding study area from January 2016 to December 2017. The particulate matter concentrations and associated elements in particulate matter were analyzed by gravimetric analysis and DBAAS, ICP-OES, Ion-Chromatography, Mercury analyzer, and CHNS analyzer.A risk level of metals in human health was occurring in the following decreasing order as Pb > Zn > Mn > Co > Cr > Ni > Hg > Cd > As, and risk level of metals in human health of carcinogenic and non-carcinogenic metals were observed to be lower than USEPA standard risk level of metals under acceptable level (10−6 year−1). The strongest association of metals areareare found for PM2.5 followed by PM10, with no indication of a threshold value for the health effects.

Abstract	Symbiotic interactions play a vital role in maintaining the phosphate (Pi) nutrient status of host plants and providing resilience during biotic and abiotic stresses. Serendipita indica, a mycorrhiza-like fungus, supports plant growth by transporting Pi to the plant. Despite the competitive behaviour of arsenate (AsV) with Pi, the association with S. indica promotes plant growth under arsenic (As) stress by reducing As bioavailability through adsorption, accumulation, and precipitation within the fungus. However, the capacity of S. indica to enhance Pi accumulation and utilization under As stress remains unexplored. Axenic studies revealed that As supply significantly reduces intracellular ACPase activity in S. indica, while extracellular ACPase remains unaffected. Further investigations using Native PAGE and gene expression studies confirmed that intracellular ACPase (isoform2) is sensitive to As, whereas extracellular ACPase (isoform1) is As-insensitive. Biochemical analysis showed that ACPase (isoform1) has a Km of 0.5977 µM and Vmax of 0.1945 Unit/min. In hydroponically cultured tomato seedlings, simultaneous inoculation of S. indica with As on the 14thday after seed germination led to hyper-colonization, increased root/shoot length, biomass, and induction of ACPase expression and secretion under As stress. Arsenic-treated S. indica colonized groups (13.33 µM As+Si and 26.67 µM As+Si) exhibited 8.28–19.14 and 1.71–3.45-fold activation of ACPase in both rhizospheric media and root samples, respectively, thereby enhancing Pi availability in the surrounding medium under As stress. Moreover, S. indica (13.33 µM As+Si and 26.67 µM As+Si) significantly improved Pi accumulation in roots by 7.26 and 9.46 times and in shoots by 4.36 and 8.85 times compared to the control. Additionally, S. indica induced the expression of SiPT under As stress, further improving Pi mobilization. Notably, fungal colonization also restricted As mobilization from the hydroponic medium to the shoot, with a higher amount of As (191.01 ppm ...

Abstract	The acid mine water body has naturally occurred in the abandoned coal mine. An acid mine water body is the major problem of high sulfur coal mining areas that generate acidic water. The acidic mine water generated contains hazardous toxic elements in varying concentrations. Water samples have been collected from an abandoned mine (Gorbi). Flyash samples have been collected from the various thermal power plants of Singrauli Coalfield. The experiment has done at the laboratory scale. The water sample has been analyzed by analytical techniques, which are pH multiparameter equipment and ICP-ES. The Morphological, geochemical and mineralogical characterization of flyash has been done using available standard techniques SEM, XRF and XRD. The laboratory investigation of the pH value of flyash indicates this has appreciable neutralization potential and may effectively be used to neutralize acid water. This research has tried to develop a treatment method of acid mine water using flyash at a laboratory scale. This paper has suggested mitigation measures and how to control the pollutants so that the ecosystem of the area gets least disturbed by the associated mining activity. The purpose of studying is to assess their suitability for dumping in pit suffering from acid mine drainage.

Abstract	Acid mine drainage (AMD) occurs naturally in abandoned coal mines, and it contains hazardous toxic elements in varying concentrations. In the present research, AMD samples collected from an abandoned mine were treated with fly ash samples from four thermal power plants in Singrauli Coalfield in the proximate area, at optimized concentrations. The AMD samples were analyzed for physicochemical parameters and metal content before and after fly ash treatment. Morphological, geochemical and mineralogical characterization of the fly ash was performed using SEM, XRF and XRD. This laboratory-scale investigation indicated that fly ash had appreciable neutralization potential, increasing AMD pH and decreasing elemental and sulfate concentrations. Therefore, fly ash may be effectively used for AMD neutralization, and its suitability for the management of coalfield AMD pits should be assessed further.

Abstract	Contamination of arsenic (As) in groundwater has increased across the world with prominence in the middle- and low-income countries. The United Nations ‘Sustainable Development Goals’ (SDG's)- ‘good health and well-being’ (SDG 3) and ‘safe and clean water and sanitation for all’ (SDG 6), cannot be achieved without monitoring and remediating ‘As’ pollution in groundwater. Over 230 million people worldwide are affected due to arsenic-contaminated drinking water. More than 200 articles discussing the ‘As’ contamination, toxicity and cost effective technology were reviewed in this study focusing on economic status of the affected nation as per World bank report. Cost budget analysis suggested that chemical oxidation followed by precipitation (0. 043-0. 076 US$/m3), low cost adsorbent (0. 1 US$/m3), hybrid treatment technologies (0. 15-0. 17 US$/m3) and biological oxidation (0. 2 US$/m3) can be applied in low income countries through community based models to mitigate the health problem related to As contamination in order to achieve SDG 3 and SDG 6 targets. This study recommends further research on budget friendly ‘As’ remediation systems and policy level interventions in the affected nations to cater safe drinking water to all.

Abstract	Optical packet switching is one of promising technology for the next generation high speed data transfer. In OPS contention among the packets is a major problem, to counteract the problem deflection and buffering of contending packets is proposed. In this paper, a six node network is considered and usability of both deflection routing and buffering of packets is discussed. The results are obtained through simulations, in terms of packet loss probability and average delay. This has been found that in general buffering of contending packets is better option in comparison to deflection. However, in case of load balancing, deflection routing is desirable as some packets take alternative routes to reach its destination. Load balancing scheme reduces the packet loss rate at contending node but it increases the total delay.

Abstract	Regression testing is used to ensure that bugs are fixed and new functionality introduce in a new version of a software that don’t adversely affect the original functionality inherited from the previous version.Regression testing is one of the most complaining activities of software development and maintenance.Unluckily, It may have feeble resources to allow for the re-execution of all test cases during regression testing. In this situation the use of test case prioritization is profitable because the best appropriate test cases are executed first. In this paper we are proposing an algorithm to prioritize test cases based on rate of fault detection and impact of fault.The proposed algorithm recognises the exhausting fault at earlier stage of the testing process.We are using an Average Percentage of Faults Detected (APFD) metric to determine the effectiveness of the new test case arrangements.

Abstract	Visibility of Ramganga river course change detection was made using Remote Sensing and GIS in study area among period of forty-one years from 1972 to 2013. Landsat MSS, TM, ETM+, LISS-III satellite images from 1972, 1989, 2000, 2006, and 2013 respectively were used to delineate the historical changes of the river course. This study shows that for a long time this area has been suffering due to erosion problem and shifting characteristics of the Ramganga River. The Ramganga river course has been shifting and the overall shifting is towards the south-west direction in different places which leads to the village erosion. The area has remained undeveloped due to infrastructure damaged by flood, changing course. This study may be helpful for the overall river management and planning for future prevention of food, changing coursing, loss of properties.
