Mahendran","doi":"10.3233/ajw230069","DOIUrl":"https://doi.org/10.3233/ajw230069","url":null,"abstract":"The use of wireless sensor networks (WSNs), in several sectors, including communication, agriculture, manufacturing, smart health, monitoring and surveillance is increasing in R&D. An IoT-based WSN in agricultural production has been effective in detecting yield conditions and automating agriculture precision by using multiple sensors. To collect data on crops, plants, temperature estimates and stickiness as well as to boost yields by making smart agriculture decisions, they are deployed in rural regions. Sensors, on the other hand, are constrained by their inability to handle, store, communicate, and process large amounts of data due to a lack of available resources. Additionally, the safety and security of the IoT-based agricultural sensors against damaging competitors are crucial factors, as is their efficacy. One idea put up in this article is to employ a WSN structure based on the Internet of Things (IoT) for smart agriculture. The selection of group leaders is also based on data collected by rural sensors and multi-rules choice capacity. A transmission link’s SNR (signal-to-noise ratio) is used to gauge the intensity of signals being sent over it in order to guarantee accurate and timely data transfer. In addition, the direct congruential generator is repeated in order to enable data flow from agricultural sensors to central stations (BS). Compared with previous arrangements, smart agriculture obtained an average of 13.5 percent in the organisation throughput, 38.5 percent in the parcel drop percentage, 13.5 percent in the organisation inactivity, and 16 percent in energy usage. Comparatively speaking, this is a huge step forward.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, an advanced catalyst Pd-doped ZnO-CdS nanocomposite was prepared using the photo deposition method. The structure and morphology of the obtained material were studied by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), examining optical properties using UV-visible spectroscopy. Results of absorption show broader bands with moderated energy band gaps and improved photocatalytic properties. The photocatalytic applications show that the increase in amount of pd/ZnO-CdS nanocomposites up to 0.4 g/L increase the number of active site, but beyond 0.4 g/L there is little increase in % degradation. Therefore, the best catalyst at 0.4 g/L was used to remove BG dye. Photo catalytic activity increase was observed for Pd/ZnO-CdS nanocomposites which is about 86.6%. Photocatalytic degradation efficiency (PDE%) increases as the dye concentration decreases from 86.66% to 26.9 %. It was observed that the photo-catalytic degradation of BG dye was 86.6%–95.8% for the first four cycles. This indicates the good stability of ZnO-CdS/Pd nano-composites and could be potentially applied in the practical batch degradation.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The industry is moving towards decarbonisation and has identified various levers to achieve the goal. Fossil fuel replacement by Alternative Fuels (AFs) has been identified as one of the levers. Refused Derived Fuel (RDF), surplus biomass, industrial waste, and other societal wastes, etc., have emerged as potential AFs; however, their use comes with technical challenges like transfer chute jamming due to the wide range of variations in their properties. Jammed transfer chute leads to the breakdown of the entire transportation system and further fluctuation in AFs feeding to the kiln/calciner. Fluctuation in the feed rate of the AFs disturbs the fuel mix ratio (mix ratio of fossil fuel and AFs) and ultimately negatively impacts the process, operation, and quality of the produced cement. Transfer chute design is often overlooked, leading to build-up, blockage, and wear in chutes. Designing of transfer chute is more challenging when handling solid alternative fuels in cement plants, as the properties of these fuels have a wide range of variation where moisture may be as high up to 40%, bulk density may vary from 0.1 to 0.75 tonnes/m3, and particle size ranges from 1 to 100 mm, etc. This study covers a survey to establish which types of AFs, and their characteristics contribute to the chute jamming problem. The outcome of this study shall help the Indian cement industry to consider the appropriate inputs for transfer chute design and selection of the correct alternative fuels and their mix to avoid chute jamming.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135143159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, studying the characteristics of solid waste dumped and the subsequent emissions of methane (CH4) from a site lacking proper disposal and gas emission management facilities, as is common in developing countries, becomes more important for suggesting appropriate corrective measures. In this study, MSW samples were collected from the Bhandewadi dumping site, a prominent site in Nagpur city and subjected to proximate, ultimate, and biochemical analysis. The results showed that the waste had high moisture content due to the tropical climate of the region which, together with the greater carbon content and organic matter (OM), may be responsible for increased overall greenhouse gas emissions. Biochemical study, on the other hand, revealed lower lignin content when compared with cellulose and hemicellulose, which are key contributors to CH4 emissions. The actual on site measurements using static chamber technique at fresh dumping sites showed that the methane (CH4) flux was between 1 and 14.3 mg m-2 sec-2 and 0.9 to 7.11 g m-3 day-2 at old dumping areas. The study contributes to a better understanding of the amount and unpredictability of methane produced by solid waste in an unmanaged dumping site.","PeriodicalId":8553,"journal":{"name":"Asian Journal of Water, Environment and Pollution","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135146617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
