Injection drug use and individuals receiving blood and blood products are the primary modes of HCV transmission. Our study aims to establish the prevalent genotypes/ subtypes of HCV circulating in Uttar Pradesh, North India, as reported from a tertiary care hospital. Methods: It is a retrospective observational analysis of consecutive 404 HCV RNA positive cases referred to our hospital during September 2014 to April 2017. The study was approved by an institutional ethics committee. Written informed consent was taken from each participant. Clinical and demographic details of these patients were recorded using predesigned questionnaires. All the laboratory testing was carried on stored serum sample of enrolled cases. Genotyping of all 404 strains was done by Sanger’s sequencing of the core region. The phylogenetic analysis of 179 HCV strains with high -quality sequencing data was performed. Results: The distribution of prevalent genotypes/ subtypes as noted in the present study was; Genotype (GT)1a [n-101(25%)], GT1b [n-12(2.9%)], GT1c [1(0.25%)], GT3a [275(68.07%)], GT3b [9(2.2%)], GT3g [2(0.49%)], GT3i [3(0.74%)], and GT4a [1(0.24%)]. HCV genotypes GT2, GT5 and GT6 were not detected from our region. Sequence analysis showed high genotypic variability in HCV GT3. Phylogenetic analysis showed that HCV GT3 and GT1 circulating in our region were related to Indian strains reported earlier. Conclusions: HCV genotypes 3a and 1a are commonest circulating genotypes in Uttar Pradesh (UP), India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hepatitis%20C%20virus" title="Hepatitis C virus">Hepatitis C virus</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20variation" title=" genetic variation"> genetic variation</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatics" title=" bioinformatics"> bioinformatics</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=HCV" title=" HCV"> HCV</a> </p> <a href="https://publications.waset.org/abstracts/98169/surveillance-of-hepatitis-c-virus-genotype-circulating-in-north-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98169.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">159</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">168</span> Clinical, Demographic and Molecular Characterization of Dengue, Chikungunya and Zika Viruses Causing Hemorrhagic Fever in North India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suruchi%20Shukla">Suruchi Shukla</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Prakash"> Shantanu Prakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Amita%20Jain"> Amita Jain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Arboviral diseases are one of the most common causes of viral hemorrhagic fever (VHF). Of which, Dengue and Chikungunya pose a significant health problem in India. Arbovirus has a tendency to cross the territories and emerge in the new region. Considering the above issues, in the current study active surveillance was conducted among viral hemorrhagic fever (VHF) cases reported from Uttar Pradesh (UP), India. We studied the arboviral etiology of VHF; mainly Dengue, Chikungunya, and ZIKA. Methods: Clinical samples of 465 suspected VHF cases referred to tertiary care referral center of UP, India were enrolled in the study during a period from 15th May 2016 to 9th March 2018. Serum specimens were collected and analyzed for the presence of Dengue, Chikungunya, and ZIKA either by serology and/or by molecular assays. Results: Of all tested, 165 (35.4%) cases were positive for either Dengue or Chikungunya. Dengue (21.2%) was found to be the most prevalent, followed by Chikungunya, (6.6%). None of the cases tested positive for ZIKA virus. Serum samples of 35 (7.5%) cases were positive for both Dengue and Chikungunya. DEN-2 serotype was the most predominant serotype. Phylogenetic and sequence analysis of DEN-2 strains showed 100% clustering with the Cosmopolitan genotype strain. Bleeding from several sites, jaundice, abdominal pain, arthralgia, haemoconcentration, and thrombocytopenia were significantly higher in dengue hemorrhagic cases. However, the rash was significantly more common in Chikungunya patients. Most of the Dengue and Chikungunya positive cases (Age group 6-40 years) were seen in post monsoon season (September to November). Conclusion: Only one-third of total VHF cases are positive for either Dengue/Chikungunya or both. This necessitates the screening of other etiologies capable of causing hemorrhagic manifestations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=viral%20hemorrhagic%20fever" title="viral hemorrhagic fever">viral hemorrhagic fever</a>, <a href="https://publications.waset.org/abstracts/search?q=dengue" title=" dengue"> dengue</a>, <a href="https://publications.waset.org/abstracts/search?q=chikungunya" title=" chikungunya"> chikungunya</a>, <a href="https://publications.waset.org/abstracts/search?q=zika" title=" zika"> zika</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a> </p> <a href="https://publications.waset.org/abstracts/98091/clinical-demographic-and-molecular-characterization-of-dengue-chikungunya-and-zika-viruses-causing-hemorrhagic-fever-in-north-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98091.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">156</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">167</span> Orientia Tsutsugamushi an Emerging Etiology of Acute Encephalitis Syndrome in Northern Part of India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amita%20Jain">Amita Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Prakash"> Shantanu Prakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Suruchi%20Shukla"> Suruchi Shukla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Acute encephalitis syndrome (AES) is a complex multi etiology syndrome posing a great public health problem in the northern part of India. Japanese encephalitis (JE) virus is an established etiology of AES in this region. Recently, Scrub typhus (ST) is being recognized as an emerging aetiology of AES in JE endemic belt. This study was conducted to establish the direct evidence of Central nervous system invasion by Orientia tsutsugamushi leading to AES. Methodology: A total of 849 cases with clinical diagnosis of AES were enrolled from six districts (Deoria and its adjoining area) of the traditional north Indian Japanese encephalitis (JE) belt. Serum and Cerebrospinal fluid samples were collected and tested for major agent causing acute encephalitis. AES cases either positive for anti-ST IgM antibodies or negative for all tested etiologies were investigated for ST-DNA by real-time PCR. Results: Of these 505 cases, 250 patients were laboratory confirmed for O. tsutsugamushi infection either by anti-ST IgM antibodies positivity (n=206) on serum sample or by ST-DNA detection by real-time PCR assay on CSF sample (n=2) or by both (n=42).Total 29 isolate could be sequenced for 56KDa gene. Conclusion: All the strains were found to cluster with Gilliam strains. The majority of the isolates showed a 97–99% sequence similarity with Thailand and Cambodian strains. Gilliam strain of O.tsusugamushi is an emerging as one of the major aetiologies leading to AES in northern part of India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20encephalitis%20syndrome" title="acute encephalitis syndrome">acute encephalitis syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=O.%20tsutsugamushi" title=" O. tsutsugamushi"> O. tsutsugamushi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilliam%20strain" title=" Gilliam strain"> Gilliam strain</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20India" title=" North India"> North India</a>, <a href="https://publications.waset.org/abstracts/search?q=cerebrospinal%20fluid" title=" cerebrospinal fluid"> cerebrospinal fluid</a> </p> <a href="https://publications.waset.org/abstracts/98168/orientia-tsutsugamushi-an-emerging-etiology-of-acute-encephalitis-syndrome-in-northern-part-of-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98168.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">250</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">166</span> The Creation of a Yeast Model for 5-oxoproline Accumulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pratiksha%20Dubey">Pratiksha Dubey</a>, <a href="https://publications.waset.org/abstracts/search?q=Praveen%20Singh"> Praveen Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Sen%20Gupta"> Shantanu Sen Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Anand%20K.%20Bachhawat"> Anand K. Bachhawat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 5-oxoproline (pyroglutamic acid) is a cyclic lactam of glutamic acid. In the cell, it can be produced by several different pathways and is metabolized into glutamate with the help of the 5-oxoprolinase enzyme (OPLAH or OXP1). The inhibition of 5-oxoprolinase enzyme in mammals was found to result in heart failure and is thought to be a consequence of oxidative stress [1]. To analyze the consequences of 5-oxoproline accumulation more clearly, we are generating models for 5-oxoproline accumulation in yeast. The 5-oxoproline accumulation model in yeast is being developed by two different strategies. The first one is by overexpression of the mouse  -glutamylcyclotransferase enzyme. It degrades -glu-met dipeptide into 5-oxoproline and methionine taken by the cell from the medium. The second strategy is by providing high concentration of 5-oxoproline externally to the yeast cells. The intracellular 5-oxoproline levels in both models are being evaluated. In addition, the metabolic and cellular consequences are being investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=5-oxoproline" title="5-oxoproline">5-oxoproline</a>, <a href="https://publications.waset.org/abstracts/search?q=pyroglutamic%20acid" title=" pyroglutamic acid"> pyroglutamic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast" title=" yeast"> yeast</a>, <a href="https://publications.waset.org/abstracts/search?q=genetics" title=" genetics"> genetics</a> </p> <a href="https://publications.waset.org/abstracts/171881/the-creation-of-a-yeast-model-for-5-oxoproline-accumulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171881.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">87</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">165</span> A System to Detect Inappropriate Messages in Online Social Networks </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shivani%20Singh">Shivani Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Nakhare"> Shantanu Nakhare</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalyani%20Nair"> Kalyani Nair</a>, <a href="https://publications.waset.org/abstracts/search?q=Rohan%20Shetty"> Rohan Shetty </a> </p> <p class="card-text"><strong>Abstract:</strong></p> As social networking is growing at a rapid pace today it is vital that we work on improving its management. Research has shown that the content present in online social networks may have significant influence on impressionable minds. If such platforms are misused, it will lead to negative consequences. Detecting insults or inappropriate messages continues to be one of the most challenging aspects of Online Social Networks (OSNs) today. We address this problem through a Machine Learning Based Soft Text Classifier approach using Support Vector Machine algorithm. The proposed system acts as a screening mechanism the alerts the user about such messages. The messages are classified according to their subject matter and each comment is labeled for the presence of profanity and insults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20social%20networks" title=" online social networks"> online social networks</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20text%20classifier" title=" soft text classifier"> soft text classifier</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a> </p> <a href="https://publications.waset.org/abstracts/22250/a-system-to-detect-inappropriate-messages-in-online-social-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22250.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">508</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">164</span> Potential Role of IL-1β in Synovial Fluid in Modulating Multiple Joint Tissue Pathologies Leading to Inflammation and Accelerating Cartilage Degeneration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priya%20Kulkarni">Priya Kulkarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumya%20Koppikar"> Soumya Koppikar</a>, <a href="https://publications.waset.org/abstracts/search?q=Datta%20Shinde"> Datta Shinde</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Deshpande"> Shantanu Deshpande</a>, <a href="https://publications.waset.org/abstracts/search?q=Narendrakumar%20Wagh"> Narendrakumar Wagh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhay%20Harsulkar"> Abhay Harsulkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Osteoarthritis (OA) is associated with multiple and overlapping aetiologies. IL-1β is produced by stressed tissue and known to aggravate disease pathologies. We selected 10 patients with elevated IL-1β in their synovial fluids (SF). We hypothesized IL-1β as nodal-point connecting different pathologies. IL-1β was higher in all meniscal tear (MT) patients perhaps as the earliest response to injury. Since MT above age of 30 leads to OA in less than 5 years, it is attributed that IL-1β modulates OA pathology. Among all bilateral OA patients, an interesting case operated for Total-Knee-Replacement revealed differential cartilage degeneration demonstrating strong association with higher IL-1β. Symptoms like acute-pain, effusion and redness were correlated with higher IL-1β and NO (Nitric-oxide). However, higher IL-1β was also found without typical-inflammation characterized by infiltration of neutrophils and macrophages. Cultured synoviocytes responded to IL-1β by releasing NO. In conclusion, IL-1β in SF acquires central position influencing different OA pathologies and aetiologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IL-1%CE%B2" title="IL-1β">IL-1β</a>, <a href="https://publications.waset.org/abstracts/search?q=meniscal%20tear" title=" meniscal tear"> meniscal tear</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoarthritis" title=" osteoarthritis"> osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=synovial%20fluid" title=" synovial fluid"> synovial fluid</a> </p> <a href="https://publications.waset.org/abstracts/6228/potential-role-of-il-1v-in-synovial-fluid-in-modulating-multiple-joint-tissue-pathologies-leading-to-inflammation-and-accelerating-cartilage-degeneration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6228.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">596</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">163</span> Semiconducting Nanostructures Based Organic Pollutant Degradation Using Natural Sunlight for Water Remediation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Gupta">Ankur Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayant%20Raj%20Saurav"> Jayant Raj Saurav</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Bhattacharya"> Shantanu Bhattacharya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work we report an effective water filtration system based on the photo catalytic performance of semiconducting dense nano-brushes under natural sunlight. During thin-film photocatalysis usually performed by a deposited layer of photocatalyst, a stagnant boundary layer is created near the catalyst which adversely affects the rate of adsorption because of diffusional restrictions. One strategy that may be used is to disrupt this laminar boundary layer by creating a super dense nanostructure near the surface of the catalyst. Further it is adequate to fabricate a structured filter element for a through pass of the water with as grown nanostructures coming out of the surface of such an element. So, the dye remediation is performed through solar means. This remediation was initially limited to lower efficiency because of diffusional restrictions but has now turned around as a fast process owing to the development of the filter materials with standing out dense nanostructures. The effect of increased surface area due to microholes on fraction adsorbed is also investigated and found that there is an optimum value of hole diameter for maximum adsorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano%20materials" title="nano materials">nano materials</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water%20treatment" title=" waste water treatment"> waste water treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20remediation" title=" water remediation"> water remediation</a> </p> <a href="https://publications.waset.org/abstracts/33109/semiconducting-nanostructures-based-organic-pollutant-degradation-using-natural-sunlight-for-water-remediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33109.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">339</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">162</span> Dual Biometrics Fusion Based Recognition System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prakash">Prakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikash%20Kumar"> Vikash Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinay%20Bansal"> Vinay Bansal</a>, <a href="https://publications.waset.org/abstracts/search?q=L.%20N.%20Das"> L.

We limit the risks of mistakes by mixing several modals, and hackers have a tiny possibility of collecting information. Our goal is to collect the precise characteristics of iris and palmprint, produce a fusion of both methodologies, and ensure that authentication is only successful when the biometrics match a particular user. After combining different modalities, we created an effective strategy with a mean DI and EER of 2.41 and 5.21, respectively.

It is a benign pseudotumor pathology. It corresponds to a non-encapsulated collection of mature adipocytes infiltrating the local tissue and hyperplasia of underlying bone leading to a craniofacial deformity. Very few cases have been reported in the literature. We report the case of a 19-year-old female patient, who was consulted for a swelling of the right hemiface progressively evolving since birth. Physical examination revealed facial asymmetry. On palpation, the mass was soft, painless, not compressible, not pulsatile, not fluctuating. In view of the asymptomatic nature and slow progression of the lesion, a lipomatous tumour, namely lipoma, was suggested. CT scan image shows a hyperplastic subcutaneous fat on the right hemiface. On the right jugal and temporal areas, there is a subcutaneous formation of fatty density, poorly limited, with no detectable peripheral capsule. It merges with the adjacent fat. In the bone window, there was a hyperplasia of underlying bone. Facial lipomatosis infiltration of the face is a benign pseudotumor pathology. As a result, it can be confused with other disorders, in particular, hemifacial hyperplasia. Combination of physical and radiological findings can establish the diagnosis. Surgical treatment is done for cosmetic purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cosmetic%20correction%20and%20facial%20assemetry" title="cosmetic correction and facial assemetry">cosmetic correction and facial assemetry</a>, <a href="https://publications.waset.org/abstracts/search?q=aesthetic%20results" title=" aesthetic results"> aesthetic results</a>, <a href="https://publications.waset.org/abstracts/search?q=facial%20infiltration" title=" facial infiltration"> facial infiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/158993/facial-infiltrating-lipomatosis-a-rare-cause-of-facial-asymmetry-to-be-known-case-report-and-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158993.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">76</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">160</span> Non-Differentiable Mond-Weir Type Symmetric Duality under Generalized Invexity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jai%20Prakash%20Verma">Jai Prakash Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Khushboo%20Verma"> Khushboo Verma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present paper, a pair of Mond-Weir type non-differentiable multiobjective second-order programming problems, involving two kernel functions, where each of the objective functions contains support function, is formulated.

Due to the massive rise in human population and modernization, environmental noise has significantly risen globally. Prolonged noise exposure can cause severe physiological and psychological symptoms like nausea, headaches, fatigue, and insomnia. There has been continuous growth in building construction and infrastructure like offices, bus stops, and airports due to the urban population. Generally, a ventilated window is used for getting fresh air into the room, but at the same time, unwanted noise comes along. Researchers used traditional approaches like noise barrier mats in front of the window or designed the entire window using sound-absorbing materials. However, this solution is not aesthetically pleasing, and at the same time, it's heavy and not adequate for low-frequency noise shielding. To address this challenge, we design a transparent hexagonal panel based on the Sierpiński fractal triangle, which is aesthetically pleasing and demonstrates a normal incident sound absorption coefficient of more than 0.96 around 700 Hz and transmission loss of around 23 dB while maintaining e air circulation through the triangular cutout. Next, we present a concept of fabrication of large acoustic panels for large-scale applications, which leads to suppressing urban noise pollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20metamaterials" title="acoustic metamaterials">acoustic metamaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=ventilation" title=" ventilation"> ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20noise%20pollution" title=" urban noise pollution"> urban noise pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20control" title=" noise control"> noise control</a> </p> <a href="https://publications.waset.org/abstracts/157321/design-of-aesthetic-acoustic-metamaterials-window-panel-based-on-sierpinski-fractal-triangle-for-sound-silencing-with-free-airflow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157321.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">108</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">158</span> Determination of Safe Ore Extraction Methodology beneath Permanent Extraction in a Lead Zinc Mine with the Help of FLAC3D Numerical Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayan%20Giri">Ayan Giri</a>, <a href="https://publications.waset.org/abstracts/search?q=Lukaranjan%20Phukan"> Lukaranjan Phukan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Karmakar"> Shantanu Karmakar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structure and tectonics play a vital role in ore genesis and deposition. The existence of a swelling structure below the current level of a mine leads to the discovery of ores below some permeant developments of the mine. The discovery and the extraction of the ore body are very critical to sustain the business requirement of the mine. The challenge was to extract the ore without hampering the global stability of the mine. In order to do so, different mining options were considered and analysed by numerical modelling in FLAC3d software. The constitutive model prepared for this simulation is the improved unified constitutive model, which can better and more accurately predict the stress-strain relationships in a continuum model. The IUCM employs the Hoek-Brown criterion to determine the instantaneous Mohr-Coulomb parameters cohesion (c) and friction (ɸ) at each level of confining stress. The extra swelled part can be dimensioned as north-south strike width 50m, east-west strike width 50m. On the north side, already a stope (P1) is excavated of the dimension of 25m NS width. The different options considered were (a) Open stoping of extraction of southern part (P0) of 50m to the full extent, (b) Extraction of the southern part of 25m, then filling of both the primaries and extraction of secondary (S0) 25m in between. (c) Extraction of the southern part (P0) completely, preceded by backfill and modify the design of the secondary (S0) for the overall stability of the permanent excavation above the stoping. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=IUCM" title=" IUCM"> IUCM</a>, <a href="https://publications.waset.org/abstracts/search?q=FLAC%203D" title=" FLAC 3D"> FLAC 3D</a>, <a href="https://publications.waset.org/abstracts/search?q=stoping" title=" stoping"> stoping</a>, <a href="https://publications.waset.org/abstracts/search?q=tectonics" title=" tectonics"> tectonics</a> </p> <a href="https://publications.waset.org/abstracts/136494/determination-of-safe-ore-extraction-methodology-beneath-permanent-extraction-in-a-lead-zinc-mine-with-the-help-of-flac3d-numerical-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136494.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">212</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">157</span> Detecting the Edge of Multiple Images in Parallel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prakash%20K.%20Aithal">Prakash K.

Currently we are using R134a as refrigerant. It is used in both household and industrial appliances as refrigerant. It has an advantage that the ozone depletion potential is zero i.e. R134a does not affects ozone layer. But its Global warming potential is considerably high. Also the compressor failure occurs frequently. Hence this project deals with how the performance of R134a varies with blended refrigerants such as R416a and R407c. This analysis is based on how much the Co-efficient of Performance (COP) varies with different refrigerants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressor" title="compressor">compressor</a>, <a href="https://publications.waset.org/abstracts/search?q=condenser" title=" condenser"> condenser</a>, <a href="https://publications.waset.org/abstracts/search?q=expansion%20valve" title=" expansion valve"> expansion valve</a>, <a href="https://publications.waset.org/abstracts/search?q=evaporator" title=" evaporator"> evaporator</a> </p> <a href="https://publications.waset.org/abstracts/28551/performance-analysis-of-vapour-compression-refrigeration-system-with-alternate-refrigerants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28551.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">323</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">155</span> A Simulation-Based Investigation of the Smooth-Wall, Radial Gravity Problem of Granular Flow through a Wedge-Shaped Hopper</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20F.%20Momin">A.

Khakhar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Granular materials consist of particulate particles found in nature and various industries that, due to gravity flow, behave macroscopically like liquids. A fundamental industrial unit operation is a hopper with inclined walls or a converging channel in which material flows downward under gravity and exits the storage bin through the bottom outlet. The simplest form of the flow corresponds to a wedge-shaped, quasi-two-dimensional geometry with smooth walls and radially directed gravitational force toward the apex of the wedge. These flows were examined using the Mohr-Coulomb criterion in the classic work of Savage (1965), while Ravi Prakash and Rao used the critical state theory (1988). The smooth-wall radial gravity (SWRG) wedge-shaped hopper is simulated using the discrete element method (DEM) to test existing theories. DEM simulations involve the solution of Newton's equations, taking particle-particle interactions into account to compute stress and velocity fields for the flow in the SWRG system. Our computational results are consistent with the predictions of Savage (1965) and Ravi Prakash and Rao (1988), except for the region near the exit, where both viscous and frictional effects are present. To further comprehend this behaviour, a parametric analysis is carried out to analyze the rheology of wedge-shaped hoppers by varying the orifice diameter, wedge angle, friction coefficient, and stiffness. The conclusion is that velocity increases as the flow rate increases but decreases as the wedge angle and friction coefficient increase. We observed no substantial changes in velocity due to varying stiffness. It is anticipated that stresses at the exit result from the transfer of momentum during particle collisions; for this reason, relationships between viscosity and shear rate are shown, and all data are collapsed into a single curve. In addition, it is demonstrated that viscosity and volume fraction exhibit power law correlations with the inertial number and that all the data collapse into a single curve. A continuum model for determining granular flows is presented using empirical correlations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discrete%20element%20method" title="discrete element method">discrete element method</a>, <a href="https://publications.waset.org/abstracts/search?q=gravity%20flow" title=" gravity flow"> gravity flow</a>, <a href="https://publications.waset.org/abstracts/search?q=smooth-wall" title=" smooth-wall"> smooth-wall</a>, <a href="https://publications.waset.org/abstracts/search?q=wedge-shaped%20hoppers" title=" wedge-shaped hoppers"> wedge-shaped hoppers</a> </p> <a href="https://publications.waset.org/abstracts/160087/a-simulation-based-investigation-of-the-smooth-wall-radial-gravity-problem-of-granular-flow-through-a-wedge-shaped-hopper" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160087.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">89</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">154</span> Fabrication of Miniature Gear of Hastelloy X by WEDM Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bhupinder%20Singh">Bhupinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Joy%20Prakash%20Misra"> Joy Prakash Misra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article provides the information regarding machining of hastelloy-X on wire electro spark machining (WEDM).

Using two soliton solution, we demonstrate different interaction behaviors of solitons in birefringent fiber depending on the choice of control parameters.

The dielectric constant and tangent loss was measured as a function of frequency from 100Hz to 1MHz at different temperatures (200-500oC). The electrical behavior was then investigated using complex impedance spectroscopy (CIS) technique. From the CIS study, it has been found that there is a contribution of both grain and grain boundary in the electrical behavior of such ceramics. Grain and grain boundary resistivity and capacitance were calculated at different temperature using CIS technique.

Bangladesh, the fourth largest Muslim majority country in the world, has been confronting the problem of VE in the name of Islam since a long. The political Islamists, explaining the events like military operations in Afghanistan and Iraq, anti-Muslim politics in neighboring India and Myanmar, Islamophobia in the West, and several other issues in their own way, have become to a vast extent successful in creating a high level of emotion, anger and a feeling of being oppressed worldwide among the ordinary Muslims masses. Half-hearted role of public intellectuals and political expediency of liberal political forces in explaining these events in a secular democratic way also facilitate the extremists to earn political dividend. VE was perceived as an all-male activism of the political Islamists’ in the past in Bangladesh. However, evidence in the recent times shows that there are sympathizers, recruiters, and perpetrators as well among the womenfolk in favor of VE-based political Islam. The first section in this paper sheds light on the way the political Islamists build rapport with and win over the heart of target women in countryside under the camouflage of preaching authentic Islam. This section also describes the role of family in involvement of women in VE. The second section discusses wide-ranging use of websites, facebook, laptop, mobile phones and several other means in the way to motivate and radicalize women. How the involvement with political Islamists brings changes in thinking process, lifestyle and family life of motivated women has been focused in the third section. The final section deals briefly with the way out relying on the argument that law and order forces alone cannot tackle this problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title="Bangladesh">Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20Islam" title=" political Islam"> political Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=violent%20extremism" title=" violent extremism"> violent extremism</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a> </p> <a href="https://publications.waset.org/abstracts/80996/from-sympathizers-to-perpetrators-examining-the-involvement-of-rural-women-in-bangladesh-in-violent-extremism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80996.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">195</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">145</span> An Efficient Approach for Speed up Non-Negative Matrix Factorization for High Dimensional Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Singh%20Om%20Prakash%20Vyas">Bharat Singh Om Prakash Vyas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Now a day’s applications deal with High Dimensional Data have tremendously used in the popular areas.
