With time, science and technology got advanced, and our society is slowly making its way to a cashless mode of transaction. But as India is still a developing country, a large part of our society still depends on transaction through cash. During times of pandemics, we came to understand that everything that we touch is not safe from microbial contamination. The Indian currency is also not an exception. The Indian currency is the modern-day medium of harmful bacterial as well as other microbial contaminations resulting in diseases in human bodies. Therefore, the need came to make the currency disinfectant to give our people a healthier lifestyle. The main focus of the study is to develop a solution that, when applied to the currency notes, will kill the persisting bacteria or microbes present in the notes. So various natural edible products were used in order to prepare the solution, which is highly effective against the presence of harmful bacteria such as E. coli and S. aureus. The antibacterial activity of these natural ingredients is not unknown to us, so extracts from those products were mixed together to form a solution which was made the Indian currency notes antibacterial for 20min approx. The solution was creating a layer on the surface of currency notes, therefore, making it antibacterial for a given duration of time, i.e., no bacterial growth was seen during the time period of 20 minutes, therefore, making it safe for the usage of human hands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indian%20currency" title="Indian currency">Indian currency</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20property%20of%20Indian%20currency" title=" antibacterial property of Indian currency"> antibacterial property of Indian currency</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20coating" title=" surface coating"> surface coating</a>, <a href="https://publications.waset.org/abstracts/search?q=currency%20disinfectant" title=" currency disinfectant"> currency disinfectant</a> </p> <a href="https://publications.waset.org/abstracts/148518/from-edible-products-to-disinfecting-currency-notes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148518.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">278</span> Microplastics in Two Bivalves of The Bay of Bengal Coast, Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Showmitra%20Chowdhury">Showmitra Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Shahadat%20Hossain"> M.

Samples were collected from four sites of the coast based on their availability, and gastrointestinal tracts were assessed following isolation, floatation, filtration, microscopic observation, and polymer identification by micro-Fourier Transformed Infrared Spectroscope (μ-FTIR) for microplastics determination. A total of 1527 microplastics were identified from 130 samples. The amount of microplastics varied from 0.66 to 3.10 microplastics/g and from 3.20 to 27.60 items/individual. Crassostrea madrasensiscontained on average 1.64 items/g and exhibited the highest level of microplastics by weight. Fiber was the most dominant type, accounting for 72% of total microplastics. Polyethylene, polypropylene, polystyrene, polyester, and nylon were the major polymer types. In both species, transparent/ black color and filamentous shape was dominant. The most common size ranges from 0.005 to 0.25mm and accounted for 39% to 67%. The study revealed microplastics pollution is widespread and relatively high in the bivalves of Bangladesh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microplastics" title="microplastics">microplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=bivalves" title=" bivalves"> bivalves</a>, <a href="https://publications.waset.org/abstracts/search?q=mussel" title=" mussel"> mussel</a>, <a href="https://publications.waset.org/abstracts/search?q=oyster" title=" oyster"> oyster</a>, <a href="https://publications.waset.org/abstracts/search?q=bay%20of%20bengal" title=" bay of bengal"> bay of bengal</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title=" Bangladesh"> Bangladesh</a> </p> <a href="https://publications.waset.org/abstracts/148905/microplastics-in-two-bivalves-of-the-bay-of-bengal-coast-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148905.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">111</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">277</span> Combined Treatment of PARP-1 Inhibitor and Carbon Ion or Gamma Exposure Reduces the Metastatic Potential in Cultured Human Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Chowdhury">Priyanka Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Asitikantha%20Sarma"> Asitikantha Sarma</a>, <a href="https://publications.waset.org/abstracts/search?q=Utpal%20Ghosh"> Utpal Ghosh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hadron therapy using high Linear Energy Transfer (LET) ion beam is producing promising clinical results worldwide. The major advantages are its ability to kill radio-resistant tumor and its anti-metastatic activity. Poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors have been widely used as radiosensitizer, but its role in metastasis is unknown. The purpose of our study was to investigate the effect of PARP-1 depletion in combination with either Carbon Ion Beam (CIB) or gamma irradiation on metastatic potential of cultured cancerous cells. A549 cells were irradiated with CIB (0-4Gy) or gamma (0, 2, 4, 6 and 10 Gy) with and without PARP-1 inhibition. The metastatic potential of the cells was determined by cell migratory assay, expression, and activity of MMP-2 and MMP-9, expression of Cadherin, Fibronectin, and Vimentin. CIB exposure reduced migratory property and activity of MMP-2 and MMP-9 significantly. CIB with PARP-1 inhibition reduced cell migration and Matrix Metalloproteinase (MMPs) activity in a synergistic manner. Expression of MMPs was also down-regulated in CIB and combined treatment. On the contrary, MMP- 2 and MMP-9 activity was significantly increased in gamma irradiated cells but decreased upon combined treatment of gamma and PARP-1 inhibitor. MMPs expression and migration was reduced when gamma irradiation was combined with PARP-1 inhibition. Thus, our study clearly demonstrates that PARP-1 inhibition in combination with either high or low LET can significantly suppress metastatic potential in cancer cells and thereby can be a promising tool in controlling metastatic cancers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20LET" title="high LET">high LET</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20LET" title=" low LET"> low LET</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix%20metalloproteinase%20%28MMP%29" title=" matrix metalloproteinase (MMP)"> matrix metalloproteinase (MMP)</a>, <a href="https://publications.waset.org/abstracts/search?q=PARP-1" title=" PARP-1"> PARP-1</a> </p> <a href="https://publications.waset.org/abstracts/76226/combined-treatment-of-parp-1-inhibitor-and-carbon-ion-or-gamma-exposure-reduces-the-metastatic-potential-in-cultured-human-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76226.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">214</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">276</span> High Prevalence of Multi-drug Resistant Diarrheagenic Escherichia coli among Hospitalised Diarrheal Patients in Kolkata, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debjani%20Ghosh">Debjani Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Chowdhury"> Goutam Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Prosenjit%20Samanta"> Prosenjit Samanta</a>, <a href="https://publications.waset.org/abstracts/search?q=Asish%20Kumar%20Mukhopadhyay"> Asish Kumar Mukhopadhyay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acute diarrhoea caused by diarrheagenic Escherichia coli (DEC) is one of the major public health problem in developing countries, mainly in Asia and Africa. DEC consists of six pathogroups, but the majority of the cases were associated with the three pathogropus, enterotoxigenic E. coli (ETEC), enteroaggregative E. coli (EAEC), and enteropathogenic E. coli (EPEC). Hence, we studied the prevalence and antimicrobial resistance of these three major DEC pathogroups in hospitalized diarrheal patients in Kolkata, India, during 2012-2019 with a large sample size. 8,891 stool samples were processed, and 7.8% of them was identified as DEC infection screened by multiplex PCR, in which ETEC was most common (47.7%) followed by EAEC (38.4%) and EPEC (13.9%). Clinical patient history suggested that children <5 years of age were mostly affected with ETEC and EAEC, whereas people within >5-14 years of age were significantly associated with EPEC and ETEC infections. Antibiogram profile showed a high prevalence of multidrug resistant (MDR) isolates among DEC (56.9%), in which 9% were resistant to antibiotics of six different antimicrobial classes. Screening of the antibiotic resistance conferring genes in DEC showed the presence of blaCTX-M (30.2%) in highest number followed by blaTEM (27.5%), tetB (18%), sul2 (12.6%), strA (11.8%), aadA1 (9.8%), blaOXA-1 (9%), dfrA1 (1.6%) and blaSHV (1.2%) which indicates the existence of mobile genetic elements in those isolates. Therefore, the presence of MDR DEC strains in higher number alarms the public health authorities to take preventive measures before the upsurge of the DEC caused diarrhea cases in near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diarrheagenic%20escherichia%20coli" title="diarrheagenic escherichia coli">diarrheagenic escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=ETEC" title=" ETEC"> ETEC</a>, <a href="https://publications.waset.org/abstracts/search?q=EAEC" title=" EAEC"> EAEC</a>, <a href="https://publications.waset.org/abstracts/search?q=EPEC" title=" EPEC"> EPEC</a> </p> <a href="https://publications.waset.org/abstracts/143560/high-prevalence-of-multi-drug-resistant-diarrheagenic-escherichia-coli-among-hospitalised-diarrheal-patients-in-kolkata-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143560.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">275</span> A New 3D Shape Descriptor Based on Multi-Resolution and Multi-Block CS-LBP</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihad%20Karim%20Chowdhury">Nihad Karim Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Sanaullah%20Chowdhury"> Mohammad Sanaullah Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammed%20Jamshed%20Alam%20Patwary"> Muhammed Jamshed Alam Patwary</a>, <a href="https://publications.waset.org/abstracts/search?q=Rubel%20Biswas"> Rubel Biswas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In content-based 3D shape retrieval system, achieving high search performance has become an important research problem. A challenging aspect of this problem is to find an effective shape descriptor which can discriminate similar shapes adequately. To address this problem, we propose a new shape descriptor for 3D shape models by combining multi-resolution with multi-block center-symmetric local binary pattern operator. Given an arbitrary 3D shape, we first apply pose normalization, and generate a set of multi-viewed 2D rendered images. Second, we apply Gaussian multi-resolution filter to generate several levels of images from each of 2D rendered image. Then, overlapped sub-images are computed for each image level of a multi-resolution image. Our unique multi-block CS-LBP comes next. It allows the center to be composed of m-by-n rectangular pixels, instead of a single pixel. This process is repeated for all the 2D rendered images, derived from both ‘depth-buffer’ and ‘silhouette’ rendering. Finally, we concatenate all the features vectors into one dimensional histogram as our proposed 3D shape descriptor. Through several experiments, we demonstrate that our proposed 3D shape descriptor outperform the previous methods by using a benchmark dataset. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20shape%20retrieval" title="3D shape retrieval">3D shape retrieval</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20shape%20descriptor" title=" 3D shape descriptor"> 3D shape descriptor</a>, <a href="https://publications.waset.org/abstracts/search?q=CS-LBP" title=" CS-LBP"> CS-LBP</a>, <a href="https://publications.waset.org/abstracts/search?q=overlapped%20sub-images" title=" overlapped sub-images"> overlapped sub-images</a> </p> <a href="https://publications.waset.org/abstracts/40165/a-new-3d-shape-descriptor-based-on-multi-resolution-and-multi-block-cs-lbp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40165.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">445</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">274</span> Enhancing Neural Connections through Music and tDCS: Insights from an fNIRS Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dileep%20G.">Dileep G.</a>, <a href="https://publications.waset.org/abstracts/search?q=Akash%20Singh"> Akash Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalchand%20%20Ahirwar"> Dalchand Ahirwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Arkadeep%20Ghosh"> Arkadeep Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashutosh%20Purohit"> Ashutosh Purohit</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Guleria"> Gaurav Guleria</a>, <a href="https://publications.waset.org/abstracts/search?q=Kshatriya%20Om%20Prashant"> Kshatriya Om Prashant</a>, <a href="https://publications.waset.org/abstracts/search?q=Pushkar%20Patel"> Pushkar Patel</a>, <a href="https://publications.waset.org/abstracts/search?q=Saksham%20Kumar"> Saksham Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanshaj%20Nathani"> Vanshaj Nathani</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikas%20Dangi"> Vikas Dangi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubhajit%20Roy%20Chowdhury"> Shubhajit Roy Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Varun%20Dutt"> Varun Dutt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transcranial direct current stimulation (tDCS) has shown promise as a novel approach to enhance cognitive performance and provide therapeutic benefits for various brain disorders. However, the exact underlying brain mechanisms are not fully understood. We conducted a study to examine the brain's functional changes when subjected to simultaneous tDCS and music (Indian classical raga). During the study, participants in the experimental group underwent a 20-minute session of tDCS at two mA while listening to music (raga) for a duration of seven days. In contrast, the control group received a sham stimulation for two minutes at two mA over the same seven-day period. The objective was to examine whether repetitive tDCS could lead to the formation of additional functional connections between the medial prefrontal cortex (the stimulated area) and the auditory cortex in comparison to a sham stimulation group. In this study, 26 participants (5 female) underwent pre- and post-intervention scans, where changes were compared after one week of either tDCS or sham stimulation in conjunction with music. The study revealed significant effects of tDCS on functional connectivity between the stimulated area and the auditory cortex. The combination of tDCS applied over the mPFC and music resulted in newly formed connections. Based on our findings, it can be inferred that applying anodal tDCS over the mPFC enhances functional connectivity between the stimulated area and the auditory cortex when compared to the effects observed with sham stimulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fNIRS" title="fNIRS">fNIRS</a>, <a href="https://publications.waset.org/abstracts/search?q=tDCS" title=" tDCS"> tDCS</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroplasticity" title=" neuroplasticity"> neuroplasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=music" title=" music"> music</a> </p> <a href="https://publications.waset.org/abstracts/168874/enhancing-neural-connections-through-music-and-tdcs-insights-from-an-fnirs-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168874.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">273</span> Nuancing the Indentured Migration in Amitav Ghosh's Sea of Poppies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murari%20Prasad">Murari Prasad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is motivated by the implications of indentured migration depicted in Amitav Ghosh’s critically acclaimed novel, Sea of Poppies (2008). Ghosh’s perspective on the experiences of North Indian indentured labourers moving from their homeland to a distant and unknown location across the seas suggests a radical attitudinal change among the migrants on board the Ibis, a schooner chartered to carry the recruits from Calcutta to Mauritius in the late 1830s. The novel unfolds the life-altering trauma of the bonded servants, including their efforts to maintain a sense of self while negotiating significant social and cultural transformations during the voyage which leads to the breakdown of familiar life-worlds. Equally, the migrants are introduced to an alternative network of relationships to ensure their survival away from land. They relinquish their entrenched beliefs and prejudices and commit themselves to a new brotherhood formed by ‘ship siblings.’ With the official abolition of direct slavery in 1833, the supply of cheap labour to the sugar plantation in British colonies as far-flung as Mauritius and Fiji to East Africa and the Caribbean sharply declined. Around the same time, China’s attempt to prohibit the illegal importation of opium from British India into China threatened the lucrative opium trade. To run the ever-profitable plantation colonies with cheap labour, Indian peasants, wrenched from their village economies, were indentured to plantations as girmitiyas (vernacularized from ‘agreement’) by the colonial government using the ploy of an optional form of recruitment. After the British conquest of the Isle of France in 1810, Mauritius became Britain’s premier sugar colony bringing waves of Indian immigrants to the island. In the articulations of their subjectivities one notices how the recruits cope with the alienating drudgery of indenture, mitigate the hardships of the voyage and forge new ties with pragmatic acts of cultural syncretism in a forward-looking autonomous community of ‘ship-siblings’ following the fracture of traditional identities. This paper tests the hypothesis that Ghosh envisions a kind of futuristic/utopian political collectivity in a hierarchically rigid, racially segregated and identity-obsessed world. In order to ground the claim and frame the complex representations of alliance and love across the boundaries of caste, religion, gender and nation, the essential methodology here is a close textual analysis of the novel. This methodology will be geared to explicate the utopian futurity that the novel gestures towards by underlining new regulations of life during voyage and dissolution of multiple differences among the indentured migrants on board the Ibis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indenture" title="indenture">indenture</a>, <a href="https://publications.waset.org/abstracts/search?q=colonial" title=" colonial"> colonial</a>, <a href="https://publications.waset.org/abstracts/search?q=opium" title=" opium"> opium</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar%20plantation" title=" sugar plantation"> sugar plantation</a> </p> <a href="https://publications.waset.org/abstracts/47117/nuancing-the-indentured-migration-in-amitav-ghoshs-sea-of-poppies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47117.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">272</span> Questioning the Predominant Feminism in Ahalya, a Short Film by Sujoy Ghosh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somya%20Sharma">Somya Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ahalya, the critically acclaimed short film, is known to demolish the gender constructs of the age old myth of Ahalya. The paper tries to crack the overt meaning of the short film by reading between the dialogues and deconstructing the idea of the pseudo feminism in the short film Ahalya by Sujoy Ghosh. The film, by subverting the role of male character by making it seem submissive as compared to the female character's role seems to be just a surface level reading of the text. It seems that Sujoy Ghosh has played not just with changing the paradigm, but also trying to alter the history by doing so. The age old myth of putting Ahalya as a part of the five virgins (panchkanya) of Hindu mythology is explored in the paper. God's manoeuvre cannot be questioned and the two male characters tend to again shape the deed and the life of the female character, Ahalya. It is of importance to note that even in the 21st century, progressive actors like Radhika Apte fail to acknowledge the politics of altering history, not in a progressive way. The film blinds the viewer in the first watch to fall for the female strength and ownership of her sexuality, which is reflected in the opening scene itself where she opens the gate for the police man Indra Sen (representing God Indra who seduced her) who is charmed by her white dress. White, in Hindu mythology, stands for mourning, and this can be a hint towards the prophecy of what is about to come. Ahalya, bold, strong, and confident in this scene seems to be in total ownership of her sexual identity. Further, as the film progresses, control of Ahalya over her acts becomes even more dominant. In the myth of Ahalya, Gautama Maharishi, her husband, who wins her by Brahma's courtesy, curses her for her infidelity. She is then turned into a stone because of the curse and is redeemed when Lord Rama's foot brushes the stone. In the film, it is with the help of Ahalya that Goutam Sadhu turns Indra Sen into a stone doll. Ahalya is seen as a seductress who bewitches Indra Sen, and because the latter falls for the trap laid by the husband wife duo, he is turned into a doll. The attempt made by the paper is to read Ahalya as a character of the stand in wife who is yet again a pawn in the play of Goutama's revenge from Indra (who in the myth is able to escape from any curse or punishment for the act). The paper, therefore, reverts the idea which has till now been signified by the film and attempts to study the feminism this film appropriates. It is essential to break down the structure formed by such overt transgressing films in order to provide a real outlook of how feminism is twisted and moulded according to a man’s wishes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deconstructing" title="deconstructing">deconstructing</a>, <a href="https://publications.waset.org/abstracts/search?q=Hindu%20mythology" title=" Hindu mythology"> Hindu mythology</a>, <a href="https://publications.waset.org/abstracts/search?q=Panchkanya" title=" Panchkanya"> Panchkanya</a>, <a href="https://publications.waset.org/abstracts/search?q=predominant%20feminism" title=" predominant feminism"> predominant feminism</a>, <a href="https://publications.waset.org/abstracts/search?q=seductress" title=" seductress"> seductress</a>, <a href="https://publications.waset.org/abstracts/search?q=stone%20doll" title=" stone doll"> stone doll</a> </p> <a href="https://publications.waset.org/abstracts/114519/questioning-the-predominant-feminism-in-ahalya-a-short-film-by-sujoy-ghosh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114519.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">254</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">271</span> Information in Public Domain: How Far It Measures Government's Accountability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Mitra">Sandip Mitra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies on Governance and Accountability has often stressed the need to release Data in public domain to increase transparency ,which otherwise act as an evidence of performance. However, inefficient handling, lack of capacity and the dynamics of transfers (especially fund transfers) are important issues which need appropriate attention. E-Governance alone can not serve as a measure of transparency as long as a comprehensive planning is instituted. Studies on Governance and public exposure has often triggered public opinion in favour or against any government. The root of the problem (especially in local governments) lies in the management of the governance. The participation of the people in the local government functioning, the networks within and outside the locality, synergy with various layers of Government are crucial in understanding the activities of any government. Unfortunately, data on such issues are not released in the public domain .If they are at all released , the extraction of information is often hindered for complicated designs.

In present work, the effect of sulfur content and its inclusions on the fatigue behavior of AISI 4140 steel is studied (sulfur content 0.002% and 0.016%). Metallurgical analysis, Mechanical testing and Rotating Bending Fatigue (RBF) test were carried out. With the increase in sulfur content, ductility and toughness of the material decrease significantly and large scatter is observed in UTS and impact energy values. From the results of RBF testing, it can be observed that increase in sulfur content from 0.002% to 0.016% has a negligible effect on the endurance strength of AISI 4140 for similar hardness level. Fractography analysis was carried out to study the failure modes in testing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AISI%204140" title="AISI 4140">AISI 4140</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfur%20content" title=" sulfur content"> sulfur content</a>, <a href="https://publications.waset.org/abstracts/search?q=MnS%20inclusion" title=" MnS inclusion"> MnS inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20bending%20fatigue" title=" rotating bending fatigue"> rotating bending fatigue</a> </p> <a href="https://publications.waset.org/abstracts/50032/effect-of-sulfur-content-on-fatigue-strength-of-aisi-4140-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50032.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">399</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">269</span> An Elaboration Likelihood Model to Evaluate Consumer Behavior on Facebook Marketplace: Trust on Seller as a Moderator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharmistha%20Chowdhury">Sharmistha Chowdhury</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuva%20Chowdhury"> Shuva Chowdhury</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Buying-selling new as well as second-hand goods like tools, furniture, household, electronics, clothing, baby stuff, vehicles, and hobbies through the Facebook marketplace has become a new paradigm for c2c sellers. This phenomenon encourages and empowers decentralised home-oriented sellers. This study adopts Elaboration Likelihood Model (ELM) to explain consumer behaviour on Facebook Marketplace (FM). ELM suggests that consumers process information through the central and peripheral routes, which eventually shape their attitudes towards posts. The central route focuses on information quality, and the peripheral route focuses on cues. Sellers’ FM posts usually include product features, prices, conditions, pictures, and pick-up location. This study uses information relevance and accuracy as central route factors. The post’s attractiveness represents cues and creates positive or negative associations with the product. A post with remarkable pictures increases the attractiveness of the post. So, post aesthetics is used as a peripheral route factor. People influenced via the central or peripheral route forms an attitude that includes multiple processes – response and purchase intention. People respond to FM posts through save, share and chat. Purchase intention reflects a positive image of the product and higher purchase intention. This study proposes trust on sellers as a moderator to test the strength of its influence on consumer attitudes and behaviour. Trust on sellers is assessed whether sellers have badges or not. A sample questionnaire will be developed and distributed among a group of random FM sellers who are selling vehicles on this platform to conduct the study. The chosen product of this study is the vehicle, a high-value purchase item. High-value purchase requires consumers to consider forming their attitude without any sign of impulsiveness seriously. Hence, vehicles are the perfect choice to test the strength of consumers attitudes and behaviour. The findings of the study add to the elaboration likelihood model and online second-hand marketplace literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20behaviour" title="consumer behaviour">consumer behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=elaboration%20likelihood%20model" title=" elaboration likelihood model"> elaboration likelihood model</a>, <a href="https://publications.waset.org/abstracts/search?q=facebook%20marketplace" title=" facebook marketplace"> facebook marketplace</a>, <a href="https://publications.waset.org/abstracts/search?q=c2c%20marketing" title=" c2c marketing"> c2c marketing</a> </p> <a href="https://publications.waset.org/abstracts/147186/an-elaboration-likelihood-model-to-evaluate-consumer-behavior-on-facebook-marketplace-trust-on-seller-as-a-moderator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147186.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">268</span> Decoloriation of Rhodamine-B Dye by Pseudomonas putida on Activated Carbon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20K.%20Ghosh">U.

The major concern of the study is to access spatial variation of groundwater quality and to identify the sources of groundwater chemicals and its impact on human health of the concerned area. Multivariate statistical techniques, cluster, principal component analysis, and hydrochemical fancies are been applied to measure groundwater quality data on 14 parameters from 107 sites distributed randomly throughout the Birbhum district. Five factors have been extracted using Varimax rotation with Kaiser Normalization. The first factor explains 27.61% of the total variance where high positive loading have been concentrated in TH, Ca, Mg, Cl and F (Fluoride). In the studied region, due to the presence of basaltic Rajmahal trap fluoride contamination is highly concentrated and that has an adverse impact on human health such as fluorosis. The second factor explains 24.41% of the total variance which includes Na, HCO₃, EC, and SO₄. The last factor or the fifth factor explains 8.85% of the total variance, and it includes pH which maintains the acidic and alkaline character of the groundwater. Hierarchical cluster analysis (HCA) grouped the 107 sampling station into two clusters. One cluster having high pollution and another cluster having less pollution. Moreover hydromorphological facies viz. Wilcox diagram, Doneen’s chart, and USSL diagram reveal the quality of the groundwater like the suitability of the groundwater for irrigation or water used for drinking purpose like permeability index of the groundwater, quality assessment of groundwater for irrigation.

In alignment with the World Health Organization's perspective on mental health as a basic human right and a crucial component for personal, community, and socioeconomic development; SAJIDA Foundation a value driven non-government organization in Bangladesh has introduced a Community Based Mental Health (CMHI) program to fill critical gaps in mental health care, providing accessible and affordable community-based services to protect and promote mental health, offering support for those grappling with mental health conditions. The CMHI programme is being implemented in 3 districts in Bangladesh, 2 of them are remote and most climate vulnerable areas targeting total 6,797 individual. The intervention plan involves a screening of all participants using a 10-point vulnerability assessment tool to identify vulnerable individuals. The assumption underlying this is that individuals assessed as vulnerable is primarily due to biological, psychological, social and economic factors and they are at an increased risk of developing common mental health issues. Those identified as vulnerable with high risk and emergency conditions will receive Mental Health First Aid (MHFA) and undergo further screening with GHQ-12 to be identified as cases and non-cases. The identified cases are then referred to community lay counsellors with basic training and knowledge in providing 4-6 sessions on problem solving or behavior activation. In situations where no improvement occurs post lay counselling or for individuals with severe mental health conditions, a referral process will be initiated, directing individuals to ensure appropriate mental health care. In our presentation, it will present the findings from 6-month pilot implementation focusing on the community-based screening versus outcome of the lay counseling session and barriers and facilitators of implementing community based mental health care in a resource constraint country like Bangladesh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community-based%20mental%20health" title="community-based mental health">community-based mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=lay%20counseling" title=" lay counseling"> lay counseling</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20bangladesh" title=" rural bangladesh"> rural bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment%20gap" title=" treatment gap"> treatment gap</a> </p> <a href="https://publications.waset.org/abstracts/186908/barriers-and-facilitators-of-community-based-mental-health-intervention-cmhi-in-rural-bangladesh-findings-from-a-descriptive-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186908.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">43</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">265</span> Modelling of Heat Transfer during Controlled Cooling of Thermo-Mechanically Treated Rebars Using Computational Fluid Dynamics Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rohit%20Agarwal">Rohit Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mrityunjay%20K.%20Singh"> Mrityunjay K.

Mahashabde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thermo-mechanical treatment (TMT) of rebars is a critical process to impart sufficient strength and ductility to rebar. TMT rebars are produced by the Tempcore process, involves an 'in-line' heat treatment in which hot rolled bar (temperature is around 1080°C) is passed through water boxes where it is quenched under high pressure water jets (temperature is around 25°C). The quenching rate dictates composite structure consisting (four non-homogenously distributed phases of rebar microstructure) pearlite-ferrite, bainite, and tempered martensite (from core to rim). The ferrite and pearlite phases present at core induce ductility to rebar while martensitic rim induces appropriate strength. The TMT process is difficult to model as it brings multitude of complex physics such as heat transfer, highly turbulent fluid flow, multicomponent and multiphase flow present in the control volume. Additionally the presence of film boiling regime (above Leidenfrost point) due to steam formation adds complexity to domain. A coupled heat transfer and fluid flow model based on computational fluid dynamics (CFD) has been developed at product technology division of Tata Steel, India which efficiently predicts temperature profile and percentage martensite rim thickness of rebar during quenching process. The model has been validated with 16 mm rolling of New Bar mill (NBM) plant of Tata Steel Limited, India. Furthermore, based on the scenario analyses, optimal configuration of nozzles was found which helped in subsequent increase in rolling speed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boiling" title="boiling">boiling</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20heat%20flux" title=" critical heat flux"> critical heat flux</a>, <a href="https://publications.waset.org/abstracts/search?q=nozzles" title=" nozzles"> nozzles</a>, <a href="https://publications.waset.org/abstracts/search?q=thermo-mechanical%20treatment" title=" thermo-mechanical treatment"> thermo-mechanical treatment</a> </p> <a href="https://publications.waset.org/abstracts/96078/modelling-of-heat-transfer-during-controlled-cooling-of-thermo-mechanically-treated-rebars-using-computational-fluid-dynamics-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96078.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">264</span> Wind Interference Effect on Tall Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atul%20K.%20Desai">Atul K.

This is development of turbulent wake region behind an upstream building. The interaction with upstream building can produce significant changes in the response of the tall building. Here, in this paper, an attempt has been made to study wind induced interference effects on tall building. In order to study wind induced interference effect (IF) on Tall Building, initially a tall building (which is termed as Principal Building now on wards) with square plan shape has been considered with different Height to Width Ratio and total drag force is obtained considering different terrain conditions as well as different incident wind direction. Then total drag force on Principal Building is obtained by considering adjacent building which is termed as Interfering Building now on wards with different terrain conditions and incident wind angle. To execute study, Computational Fluid Dynamics (CFD) Code namely Fluent and Gambit have been used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=tall%20building" title=" tall building"> tall building</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent" title=" turbulent"> turbulent</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20region" title=" wake region"> wake region</a>, <a href="https://publications.waset.org/abstracts/search?q=wind" title=" wind"> wind</a> </p> <a href="https://publications.waset.org/abstracts/6233/wind-interference-effect-on-tall-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6233.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">551</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">263</span> Emergency Treatment of Methanol Poisoning: A Mathematical Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Ghosh">Priyanka Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Priti%20Kumar%20Roy"> Priti Kumar Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Every year a considerable number of people die due to methyl alcohol poisoning, in which most of them die even before proper treatment.

The highest mineralization rate of 86.83% was achieved for O3/UV/Persulfate followed by 71.53% and 66.82 % for O3/UV and O3 respectively. This is attributed to the fact that Persulfate ions (S2O82-) upon activation produce sulfate radical (SO4-●) which is very strong oxidant capable of degrading a wide variety of recalcitrant organic compounds, moreover to enhance the performance of Persulfate it is activated using UV irradiation. On increasing the intensity of UV irradiation from 11W to 66W, TOC removal efficiency is increased by 59.04%. Ozone based AOPs gives better mineralization on basic conditions, at pH 12 it gives 68.81%, 60.01% and 40.32% TOC removal for O3/UV/Persulfate, O3/UV and O3 process respectively. The result also reveals that decolorization of 98.95%, 95.17% and 94.71% was achieved by O3/UV/Persulfate, O3/UV and O3 process respectively. In addition to above, ozone consumption was also considerably decreased by 17% in case of O3/UV/Persulfate, as efficiency of process is enhanced by means of activation of persulfate through UV irradiation. Thus study reveals that mineralization follows: O3/UV/Persulfate> O3/UV> O3. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AOP" title="AOP">AOP</a>, <a href="https://publications.waset.org/abstracts/search?q=mineralization" title=" mineralization"> mineralization</a>, <a href="https://publications.waset.org/abstracts/search?q=TOC" title=" TOC"> TOC</a>, <a href="https://publications.waset.org/abstracts/search?q=recalcitrant%20organic%20compounds" title=" recalcitrant organic compounds"> recalcitrant organic compounds</a> </p> <a href="https://publications.waset.org/abstracts/41576/comparative-study-of-ozone-based-aops-for-mineralization-of-reactive-black-5" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41576.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">227</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">255</span> Synthesis of 2-Aminoisocoumarinoselenazoles via Transition Metal-Free Alkylation and Ru(II)-Catalyzed [4+2] Alkyne Annulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Kumar">Sunil Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Dhole"> Sandip Dhole</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Salunke"> Deepak Salunke</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-ming%20Sun"> Chung-ming Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heterocycles bearing nitrogen, oxygen, and selenium are present in innumerable biologically active compounds. For instance, coumarin containing dicoumarol acts as naturally occurring anticoagulant. 2-Acylamido selenazole works as Store-Operated Calcium (SOC) channel regulator. Therefore, due to biologically significance of selenazole and coumarin and our quest to develop efficient methodologies for the synthesis of complex heterocycles, the trisubstituted angular isocoumarinoselenazole synthesis was proposed and achieved by starting from nitrobenzoic acid derivative, available commercially. Synthetic procedure involves three steps: i) the construction of 2-aminobenzoselenazoles, ii) their regioselective N-alkylation at position-2 and iii) alkyne insertion via Ru catalyzed C-H activation. Transition metal free synthesis of benzoselenazoles was successfully brought about by the addition/elimination reaction via intramolecular C-Se bond formation. In the next step, N-alkylation of selenazole furnished two regioisomers. Both the isomers exhibited different reactivity towards [4+2] alkyne annulation reaction. The fusion of α-pyrone ring on the benzo[1,3-d]selenazole skeleton was achieved via Ru(II)-catalyzed C-H activation and alkyne insertion. As evident from mechanism, the selenazole 'N' plays an important role for the experiential selectivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkylation" title="alkylation">alkylation</a>, <a href="https://publications.waset.org/abstracts/search?q=alkyne%20insertion" title=" alkyne insertion"> alkyne insertion</a>, <a href="https://publications.waset.org/abstracts/search?q=coumarin" title=" coumarin"> coumarin</a>, <a href="https://publications.waset.org/abstracts/search?q=selenazole" title=" selenazole "> selenazole </a> </p> <a href="https://publications.waset.org/abstracts/125051/synthesis-of-2-aminoisocoumarinoselenazoles-via-transition-metal-free-alkylation-and-ruii-catalyzed-42-alkyne-annulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125051.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">254</span> Attention Based Fully Convolutional Neural Network for Simultaneous Detection and Segmentation of Optic Disc in Retinal Fundus Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandip%20Sadhukhan">Sandip Sadhukhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Arpita%20Sarkar"> Arpita Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Debprasad%20Sinha"> Debprasad Sinha</a>, <a href="https://publications.waset.org/abstracts/search?q=Goutam%20Kumar%20Ghorai"> Goutam Kumar Ghorai</a>, <a href="https://publications.waset.org/abstracts/search?q=Gautam%20Sarkar"> Gautam Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashis%20K.%20Dhara"> Ashis K.

The paper presents an accurate and fast optic disc detection and segmentation method using an attention based fully convolutional network. The network is trained from scratch using the fundus images of extended MESSIDOR database and the trained model is used for segmentation of optic disc. The false positives are removed based on morphological operation and shape features. The result is evaluated using three-fold cross-validation on six public fundus image databases such as DIARETDB0, DIARETDB1, DRIVE, AV-INSPIRE, CHASE DB1 and MESSIDOR. The attention based fully convolutional network is robust and effective for detection and segmentation of optic disc in the images affected by diabetic retinopathy and it outperforms existing techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attention-based%20fully%20convolutional%20network" title="attention-based fully convolutional network">attention-based fully convolutional network</a>, <a href="https://publications.waset.org/abstracts/search?q=optic%20disc%20detection%20and%20segmentation" title=" optic disc detection and segmentation"> optic disc detection and segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=retinal%20fundus%20image" title=" retinal fundus image"> retinal fundus image</a>, <a href="https://publications.waset.org/abstracts/search?q=screening%20of%20ocular%20diseases" title=" screening of ocular diseases"> screening of ocular diseases</a> </p> <a href="https://publications.waset.org/abstracts/112293/attention-based-fully-convolutional-neural-network-for-simultaneous-detection-and-segmentation-of-optic-disc-in-retinal-fundus-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112293.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">253</span> Failure and Stress Analysis of Super Heater Tubes of a 67 TPH Coke Dry Quenching Boiler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Subodh%20N.%20Patel">Subodh N.

There were two superheaters in the system, SH I and SH II. SH II is a set of tubes that faces the initial interaction with flue gas at high temperature followed by SH I tubes. After a service life of 2100 hours, a tube in the SH II found to be punctured. Dye penetrant test revealed that out of 50 such tubes, 14 more tubes had severe cracks at a similar location. The failure was investigated in detail. The materials and scale were characterized by optical microscope and advance characterization technique. Scale, observed on fracture surface, was characterized under scanning electron microscope and Raman spectroscopy. Stresses acting on the tubes in working condition were analyzed by finite element method software, ANSYS. Cyclic stresses were observed in the simulation at the same prone location due to restriction in expansion of tubes. Based on scale characterization and stress analysis, it was concluded that the tube failed in thermo-mechanical fatigue. Finally, prevention and control measures were taken to avoid such failure in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=oxide%20scale" title=" oxide scale"> oxide scale</a>, <a href="https://publications.waset.org/abstracts/search?q=superheater%20tube" title=" superheater tube"> superheater tube</a>, <a href="https://publications.waset.org/abstracts/search?q=thermomechanical%20fatigue" title=" thermomechanical fatigue"> thermomechanical fatigue</a> </p> <a href="https://publications.waset.org/abstracts/107171/failure-and-stress-analysis-of-super-heater-tubes-of-a-67-tph-coke-dry-quenching-boiler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107171.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">117</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">252</span> Achieving Better Security by Using Nonlinear Cellular Automata as a Cryptographic Primitive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swapan%20Maiti">Swapan Maiti</a>, <a href="https://publications.waset.org/abstracts/search?q=Dipanwita%20Roy%20Chowdhury"> Dipanwita Roy Chowdhury</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nonlinear functions are essential in different cryptoprimitives as they play an important role on the security of the cipher designs. Rule 30 was identified as a powerful nonlinear function for cryptographic applications. However, an attack (MS attack) was mounted against Rule 30 Cellular Automata (CA). Nonlinear rules as well as maximum period CA increase randomness property. In this work, nonlinear rules of maximum period nonlinear hybrid CA (M-NHCA) are studied and it is shown to be a better crypto-primitive than Rule 30 CA. It has also been analysed that the M-NHCA with single nonlinearity injection proposed in the literature is vulnerable against MS attack, whereas M-NHCA with multiple nonlinearity injections provide maximum length cycle as well as better cryptographic primitives and they are also secure against MS attack. <p class="card-text"><strong>Keywords:</strong> <a
