The Laplace equation was solved at each panel by applying the boundary conditions. The boundary condition was applied at each panel to mathematically formulate the problem and then convert the problem into a computer-solvable problem. Kutta condition was applied at both the leading and trailing edges to see whether the condition is satisfied or not. Another approach that is applied for the analysis is Vortex Lattice Method (VLM). A vortex ring is considered at each control point. Using the Biot-Savart Law the strength at each control point is calculated and hence the pressure differentials are measured. For the comparison of the analytic result with the experimental result, different NACA section hydrofoil is used. The analytic result of NACA 0012 and NACA 0015 are compared with the experimental result of Abbott and Doenhoff and found significant conformity with the achieved result. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kutta%20condition" title="Kutta condition">Kutta condition</a>, <a href="https://publications.waset.org/abstracts/search?q=Law%20of%20Biot-Savart" title=" Law of Biot-Savart"> Law of Biot-Savart</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20differentials" title=" pressure differentials"> pressure differentials</a>, <a href="https://publications.waset.org/abstracts/search?q=potential%20flow" title=" potential flow"> potential flow</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20lattice%20method" title=" vortex lattice method"> vortex lattice method</a> </p> <a href="https://publications.waset.org/abstracts/81177/analysis-of-potential-flow-around-two-dimensional-body-by-surface-panel-method-and-vortex-lattice-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81177.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">190</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> Fluid-Structure Interaction Study of Fluid Flow past Marine Turbine Blade Designed by Using Blade Element Theory and Momentum Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abu%20Afree%20Andalib">Abu Afree Andalib</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Mezbah%20Uddin"> M.

The designed blade is analyzed for various parameters using FSI module of Ansys. Computational Fluid Dynamics is used for the study of fluid flow past the blade and other fluidic phenomena such as lift, drag, pressure differentials, energy dissipation in water. Finite Element Analysis (FEA) module of Ansys was used to analyze the structural parameter such as stress and stress density, localization point, deflection, force propagation. Fine mesh is considered in every case for more accuracy in the result according to computational machine power. The relevance of design, search and optimization with respect to complex fluid flow and structural modeling is considered and analyzed. The relevancy of design and optimization with respect to complex fluid for minimum drag force using Ansys Adjoint Solver module is analyzed as well. The graphical comparison of the above-mentioned parameter using CFD and FEA and subsequently FSI technique is illustrated and found the significant conformity between both the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blade%20element%20theory" title="blade element theory">blade element theory</a>, <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=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid-structure%20interaction" title=" fluid-structure interaction"> fluid-structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=momentum%20theory" title=" momentum theory"> momentum theory</a> </p> <a href="https://publications.waset.org/abstracts/81379/fluid-structure-interaction-study-of-fluid-flow-past-marine-turbine-blade-designed-by-using-blade-element-theory-and-momentum-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81379.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">301</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> Based on MR Spectroscopy, Metabolite Ratio Analysis of MRI Images for Metastatic Lesion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossain%20A">Hossain A</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossain%20S."> Hossain S.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: In a small cohort, we sought to assess the magnetic resonance spectroscopy's (MRS) ability to predict the presence of metastatic lesions. Method: A Popular Diagnostic Centre Limited enrolled patients with neuroepithelial tumors. The 1H CSI MRS of the brain allows us to detect changes in the concentration of specific metabolites caused by metastatic lesions. Among these metabolites are N-acetyl-aspartate (NNA), creatine (Cr), and choline (Cho). For Cho, NAA, Cr, and Cr₂, the metabolic ratio was calculated using the division method. Results: The NAA values were 0.63 and 5.65 for tumor cells, 1.86 and 5.66 for normal cells, and 1.86 and 5.66 for normal cells 2. NAA values for normal cells 1 were 1.84, 10.6, and 1.86 for normal cells 2, respectively. Cho levels were as low as 0.8 and 10.53 in the tumor cell, compared to 1.12 and 2.7 in the normal cell 1 and 1.24 and 6.36 in the normal cell 2. Cho/Cr₂ barely distinguished itself from the other ratios in terms of significance. For tumor cells, the ratios of Cho/NAA, Cho/Cr₂, NAA/Cho, and NAA/Cr₂ were significant. Normal cell 1 had significant Cho/NAA, Cho/Cr, NAA/Cho, and NAA/Cr ratios. Conclusion: The clinical result can be improved by using 1H-MRSI to guide the size of resection for metastatic lesions. Even though it is non-invasive and doesn't present any difficulties during the procedure, MRS has been shown to predict the detection of metastatic lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metabolite%20ratio" title="metabolite ratio">metabolite ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=MRI%20images" title=" MRI images"> MRI images</a>, <a href="https://publications.waset.org/abstracts/search?q=metastatic%20lesion" title=" metastatic lesion"> metastatic lesion</a>, <a href="https://publications.waset.org/abstracts/search?q=MR%20spectroscopy" title=" MR spectroscopy"> MR spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=N-acetyl-aspartate" title=" N-acetyl-aspartate"> N-acetyl-aspartate</a> </p> <a href="https://publications.waset.org/abstracts/154048/based-on-mr-spectroscopy-metabolite-ratio-analysis-of-mri-images-for-metastatic-lesion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154048.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">97</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">161</span> Association Rules Mining Task Using Metaheuristics: Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abir%20Derouiche">Abir Derouiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdesslem%20Layeb"> Abdesslem Layeb </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Association Rule Mining (ARM) is one of the most popular data mining tasks and it is widely used in various areas.

This paper will explore Charlotte Perkins Gilman’s feminist utopia Herland (1915) with another feminist utopia written just a decade before, but in a widely different sociopolitical context: Bengali feminist writer Rokeya Sakhawat Hossain’s English short story Sultana’s Dream (1905). The paper will argue that both texts, despite being written in such different cultural and historical contexts, utilize and subvert the public versus private/domestic sphere dichotomy and the restricted gender roles associated with each sphere in order to conceive of specific formulations of feminist modernities that reflect the sociopolitical contexts and feminist movements both writers were writing within. By bringing Gilman’s Herland into conversation with Hossain’s Sultana’s Dream, the paper hopes to illuminate the new meanings that might emerge if the scholarship on Western feminist utopias was to open itself up to the feminist utopias written elsewhere. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comparative%20literature" title="comparative literature">comparative literature</a>, <a href="https://publications.waset.org/abstracts/search?q=feminist%20utopias" title=" feminist utopias"> feminist utopias</a>, <a href="https://publications.waset.org/abstracts/search?q=modernity" title=" modernity"> modernity</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Asian%20literature" title=" South Asian literature"> South Asian literature</a>, <a href="https://publications.waset.org/abstracts/search?q=utopias" title=" utopias"> utopias</a> </p> <a href="https://publications.waset.org/abstracts/82291/modernity-and-domestic-space-in-the-feminist-utopias-of-herland-and-sultanas-dream" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82291.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">240</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">159</span> Perspective and Challenge of Tidal Power in Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Alamgir%20Hossain">Md.

It can reduce the present energy crisis and improve the social, environmental and economic perspective of Bangladesh. Tidal energy is becoming popular around the world due to its own facilities. The development of any country largely depends on energy sector improvement. Lack of energy sector is because of hampering progress of any country development, and the energy sector will be stable by only depend on sustainable energy sources. Renewable energy having environmental friendly is the only sustainable solution of secure energy system. Bangladesh has a huge potential of tidal power at different locations, but effective measures on this issue have not been considered sincerely. This paper summarizes the current energy scenario, and Bangladesh can produce power approximately 53.19 MW across the country to reduce the growing energy demand utilizing tidal energy as well as it is shown that Sandwip is highly potential place to produce tidal power, which is estimated approximately 16.49 MW by investing only US $10.37 million. Besides this, cost management for tidal power plant has been also discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20energy" title="sustainable energy">sustainable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=tidal%20power" title=" tidal power"> tidal power</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20analysis" title=" cost analysis"> cost analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20demand" title=" power demand"> power demand</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20crisis" title=" gas crisis "> gas crisis </a> </p> <a href="https://publications.waset.org/abstracts/13732/perspective-and-challenge-of-tidal-power-in-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13732.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">494</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> A CORDIC Based Design Technique for Efficient Computation of DCT</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deboraj%20Muchahary">Deboraj Muchahary</a>, <a href="https://publications.waset.org/abstracts/search?q=Amlan%20Deep%20Borah%20Abir%20J.%20Mondal"> Amlan Deep Borah Abir J.

The estimated contribution of agricultural carbon dioxide (CO₂) and methane (CH₄) to global warming potential (GWP) has a wide range. The underlying causes of this huge uncertainty are the difficulties to predict the regional CO₂ and CH₄ loss due to the lack of experimental evidence on CO₂ and CH₄ emissions and associated drivers. The CH₄ and CO₂ emissions were measured in irrigated wheat in subtropical floodplain soils which have been under two soil disturbance levels (strip vs. conventional tillage; ST vs. CT being both with 30% residue retention) and three N fertilizer rates (60, 100, and 140% of the recommended N fertilizer dose, RD) in annual wheat (Triticum aestivum)-mungbean (Vigna radiata)-rice (Oryza sativa L) for seven consecutive years. The highest CH₄ and CO₂ emission peak was observed on day 3 after urea application in both tillages except CO₂ flux in CT. Nitrogen fertilizer application rate significantly influenced mean and cumulative CH₄ and CO₂ fluxes. The CH₄ and CO₂ fluxes decreased in an optimum dose of N fertilizer except for ST for CH₄. The CO₂ emission significantly showed higher emission at minimum (60% of RD) fertilizer application at both tillages. Soil microbial biomass carbon (MBC), organic carbon (SOC), Particulate organic carbon (POC), permanganate oxidisable carbon (POXC), basal respiration (BR) were significantly higher in ST which were negative and significantly correlated with CO₂. However, POC and POXC were positively and significantly correlated with CH₄ emission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20emissions" title="carbon dioxide emissions">carbon dioxide emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=methane%20emission" title=" methane emission"> methane emission</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen%20rate" title=" nitrogen rate"> nitrogen rate</a>, <a href="https://publications.waset.org/abstracts/search?q=tillage" title=" tillage"> tillage</a> </p> <a href="https://publications.waset.org/abstracts/168130/carbon-dioxide-co2-and-methane-ch4-fluxes-from-irrigated-wheat-in-a-subtropical-floodplain-soil-increased-by-reduced-tillage-residue-retention-and-nitrogen-application-rate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168130.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">116</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> Challenges of Management of Acute Pancreatitis in Low Resource Setting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Shakhawat%20Hossain">Md.

Management of acute pancreatitis needs multidisciplinary approach with support starts from emergency to ICU. So, there is a chance of mismanagement in every steps, especially in low resource settings. Other factors such as patient’s financial condition, education, social custom, transport facility, referral system from periphery may also challenge the current guidelines for management. The present study is intended to determine the clinico-pathological profile, severity assessment and challenges of management of acute pancreatitis in a government laid tertiary care hospital to image the real scenario of management in a low resource place. A total 100 patients of acute pancreatitis were studied in this prospective study, held in the Department of Gastroenterology, Rangpur medical college hospital, Bangladesh from July 2017 to July 2018 within one year. Regarding severity, 85 % of the patients were mild, whereas 13 were moderately severe, and 2 had severe acute pancreatitis according to the revised Atlanta criteria. The most common etiologies of acute pancreatitis in our study were gall stone (15%) and biliary sludge (15%), whereas 54% were idiopathic. The most common challenges we faced were delay in hospital admission (59%) and delay in hospital diagnosis (20%). Others are non-adherence of patient party, and lack of investigation facility, physician’s poor knowledge about current guidelines. We were able to give early aggressive fluid to only 18% of patients as per current guideline. Conclusion: Management of acute pancreatitis as per guideline is challenging when optimum facility is lacking. So, modified guidelines for assessment and management of acute pancreatitis should be prepared for low resource setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20pancreatitis" title="acute pancreatitis">acute pancreatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=challenges%20of%20management" title=" challenges of management"> challenges of management</a>, <a href="https://publications.waset.org/abstracts/search?q=severity" title=" severity"> severity</a>, <a href="https://publications.waset.org/abstracts/search?q=prognosis" title=" prognosis"> prognosis</a> </p> <a href="https://publications.waset.org/abstracts/112286/challenges-of-management-of-acute-pancreatitis-in-low-resource-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112286.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">129</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> Parametric Analysis of Solid Oxide Fuel Cell Using Lattice Boltzmann Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abir%20Yahya">Abir Yahya</a>, <a href="https://publications.waset.org/abstracts/search?q=Hacen%20Dhahri"> Hacen Dhahri</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalifa%20Slimi"> Khalifa Slimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper deals with a numerical simulation of temperature field inside a solid oxide fuel cell (SOFC) components.

However, scholars have not agreed on the key factors that impact entrepreneurial intention. This study attempts, through an extensive literature review, to provide a holistic view and a more comprehensive understanding of the key factors that lead university undergraduate students to become entrepreneurs. A systematic literature review is conducted and several scientific articles and reports have been examined. The results of this study indicate that there are four main sets of factors: the personality-traits factors, contextual factors, motivational factors, and personal background factors.

This is due to the ability of nitro group to form hydrogen bonding with hydroxyl group of the glucopyranose ring which increases the crystallinity of polymeric matrix.

The main goal of this research is to explore the college students’ motives for using SNSs in education. A conceptual framework has therefore been developed to identify the main factors that influence/motivate students to use social networking sites for learning purposes. To achieve the research objectives a quantitative method was used to collect data. A questionnaire has been distributed amongst college students. The results reveal that social influence, perceived enjoyment, institute regulation, perceived usefulness, ranking up-lift, attractiveness, communication tools, free of charge, sharing material and course nature all play an important role in the motivation of college students to use SNSs for learning purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Social%20Networking%20Sites%20%28SNSs%29" title="Social Networking Sites (SNSs)">Social Networking Sites (SNSs)</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=college%20students" title=" college students"> college students</a>, <a href="https://publications.waset.org/abstracts/search?q=motivations" title=" motivations"> motivations</a> </p> <a href="https://publications.waset.org/abstracts/12537/motivations-for-using-social-networking-sites-by-college-students-for-educational-purposes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12537.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">263</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">147</span> Morphometric Relationships of Length-Weight and Length-Length of Oreochromis aureus in Relation to Body Size and Condition Factor from Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naeem">Muhammad Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdus%20Salam"> Abdus Salam</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumera%20Yasmin"> Sumera Yasmin</a>, <a href="https://publications.waset.org/abstracts/search?q=Abir%20Ishtiaq"> Abir Ishtiaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, eighty-three wild Oreochromis aureus of different body size ranging 5.3-14.6 cm in total length were collected from the River Chenab, District Muzzafer Garh, Pakistan to investigate the parameters of length –weight, length-length relationships and condition factor in relation to size.

Some have used it as an example to establish nuclear energy as an unsafe source, while others have tried to find the real reasons behind this accident. Many papers have tried to shed light on the possible causes, some of which are purely based on assumptions while others rely on rigorous data analysis. To our best knowledge, none of the works can say with absolute certainty that there is a single prominent reason that has paved the way to this unexpected incident.

CA suffers from high degree of water permeability as well as the low thermal stability at high temperatures. To adjust the CA polymeric films to the manufacture of food packaging, its thermal and mechanical properties should be improved. The modification of CA by grafting it with N-Amino phenyl maleimide (N-APhM) led to the construction of hydrophobic branches throughout the polymeric matrix which reduced its wettability as compared to the parent CA. The branches built onto the polymeric chains had been characterized by UV/Vis, <sup>13</sup>C-NMR and ESEM. The improvement of the thermal properties was investigated and compared to the parent CA using thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), differential thermal analysis (DTA), contact angle and mechanical testing measurements. The results revealed that the water-uptake was reduced by increasing the graft percentage. The thermal and mechanical properties were also improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellulose%20acetate" title="cellulose acetate">cellulose acetate</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20packaging" title=" food packaging"> food packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=graft%20copolymerization" title=" graft copolymerization"> graft copolymerization</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title=" thermal properties"> thermal properties</a> </p> <a href="https://publications.waset.org/abstracts/88229/biodegradable-cellulose-based-materials-for-the-use-in-food-packaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88229.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">222</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">142</span> Analytical Solution for End Depth Ratio in Rectangular Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulrahman%20Abdulrahman">Abdulrahman Abdulrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Abir%20Abdulrahman"> Abir Abdulrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Free over-fall is an instrument for measuring discharge in open channels by measuring end depth. A comprehensive researchers investigated theoretically and experimentally brink phenomenon with various approaches for different cross-sectional shapes. Anderson's method, based on Boussinq's approximation and energy approach was used to derive a pressure distribution factor at end depth. Applying the one-dimensional momentum equation and the principles of limit slope analysis, a relevant analytical solution may be derived for brink depth ratio (EDR) in prismatic rectangular channel. Also relationships between end depth ratio and slope ratio for a given non-dimensional normal or critical depth with upstream supercritical flow regime are presented. Simple indirect procedure is used to estimate the end depth discharge ratio (EDD) for subcritical and supercritical flow using measured end depth. The comparison of this analysis with all previous theoretical and experimental studies showed an excellent agreement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title="analytical solution">analytical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=brink%20depth" title=" brink depth"> brink depth</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20depth" title=" end depth"> end depth</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20measurement" title=" flow measurement"> flow measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20over%20fall" title=" free over fall"> free over fall</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulics" title=" hydraulics"> hydraulics</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangular%20channel" title=" rectangular channel"> rectangular channel</a> </p> <a href="https://publications.waset.org/abstracts/92286/analytical-solution-for-end-depth-ratio-in-rectangular-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92286.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">181</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">141</span> Design Optimization of the Primary Containment Building of a Pressurized Water Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Hossain">M.

The neutron rich even-even isotopes of Ru are very interesting to investigate using IBM-1, because even 104,106Ru isotopes are great consequence due to excited near the magic number 50. The calculation of ground state band and B(E2) values using IBM-1 for Z=44 are not calculated to describe the valuable information of nuclear structure by U(5) limit. The parameters in the formula are deduced based on the experimental energy level and value of B(E2, 2+->0+). The yrast states and transition strength B(E2) from 1st 4+ to 1st 2+, 1st 6+ to 1st 4+ and 1st 8+ to 1st 6+ states of Ru for even N= 60, 62 were calculated. The quadrupole moments, deformation parameters and U(5) limit were discussed for those nuclei. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=B%28E2%29" title="B(E2)">B(E2)</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20level" title=" energy level"> energy level</a>, <a href="https://publications.waset.org/abstracts/search?q=%C2%B9%E2%81%B0%E2%81%B4Ru" title=" ¹⁰⁴Ru"> ¹⁰⁴Ru</a>, <a href="https://publications.waset.org/abstracts/search?q=%C2%B9%E2%81%B0%E2%81%B6Ru" title=" ¹⁰⁶Ru"> ¹⁰⁶Ru</a> </p> <a href="https://publications.waset.org/abstracts/56470/ground-states-of-structure-of-even-14-16-ru-isotopes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56470.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">348</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">139</span> Evaluation of Antioxidant and Anticancer Activity of Tinospora cordifolia against Ehrlich Ascites Carcinoma: In Vitro, in vivo and in silico Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anik%20Barua">Anik Barua</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabiul%20Hossain"> Rabiul Hossain</a>, <a href="https://publications.waset.org/abstracts/search?q=Labonno%20Barua"> Labonno Barua</a>, <a href="https://publications.waset.org/abstracts/search?q=Rashadul%20Hossain"> Rashadul Hossain</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Absar"> Nurul Absar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Globally, the burden of cancer is increasing consistently. Modern cancer therapies include lots of toxicity in the non-targeted organs reducing the life expectancy of the patients. Hence, scientists are trying to seek noble compounds from natural sources to treat cancer. Objectives: The objectives of the present study are to evaluate the phytochemicals, in vitro antioxidants, and in vivo and in silico anticancer study of various solvent fractions of Tinospora cordifolia (Willd.). Methodology: In this experiment, standard quantitative and qualitative assay methods were used to analyze the phytochemicals. The antioxidant activity was measured using the DPPH and ABTS scavenging methods. The in vivo antitumor activity is evaluated against Ehrlich ascites carcinoma (EAC) cell bearing in Swiss albino mice. In-silico ADME/T and molecular docking study were performed to assess the potential of stated phytochemicals against Transcription Factor STAT3b/DNA Complex of adenocarcinoma. Findings: Phytochemical screening confirmed the presence of flavonoids, alkaloids, glycosides, tannins, and carbohydrates. A significant amount of phenolic (20.19±0.3 mg/g GAE) and flavonoids (9.46±0.18 mg/g GAE) were found in methanolic extract in quantitative screening. Tinospora cordifolia methanolic extract showed promising DPPH and ABTS scavenging activity with the IC50 value of 1222.99 µg/mL and 1534.34 µg/mL, respectively, which was concentration dependent. In vivo anticancer activity in EAC cell-bearing mice showed significant (P < 0.05) percent inhibition of cell growth (60.12±1.22) was found at the highest dose compared with standard drug 5-Fluorouracil (81.18±1.28). Forty-two phytochemicals exhibit notable pharmacokinetics properties and passed drug-likeness screening tests in silico. In molecular docking study, (25S)-3Beta-acetoxy-5-alpha-22-beta-spirost-9(11)-en-12-beta-ol showed docking score (-8.5 kJ/mol) with significant non-bonding interactions with target enzyme. Conclusions: The results were found to be significant and confirmed that the methanolic extract of Tinospora cordifolia has remarkable antitumor activity with antioxidant potential. The Tinospora cordifolia methanolic extract may be considered a potent anticancer agent for advanced research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer" title="anticancer">anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=Tinospora%20cordifolia" title=" Tinospora cordifolia"> Tinospora cordifolia</a>, <a href="https://publications.waset.org/abstracts/search?q=EAC%20cell" title=" EAC cell"> EAC cell</a> </p> <a href="https://publications.waset.org/abstracts/157005/evaluation-of-antioxidant-and-anticancer-activity-of-tinospora-cordifolia-against-ehrlich-ascites-carcinoma-in-vitro-in-vivo-and-in-silico-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157005.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">129</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">138</span> Effect of Atmospheric Turbulence on Hybrid FSO/RF Link Availability under Qatar's Harsh Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abir%20Touati">Abir Touati</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Jawad%20Hussain"> Syed Jawad Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Touati"> Farid Touati</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Bouallegue"> Ammar Bouallegue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although there has been a growing interest in the hybrid free-space optical link and radio frequency FSO/RF communication system, the current literature is limited to results obtained in moderate or cold environment. In this paper, using a soft switching approach, we investigate the effect of weather inhomogeneities on the strength of turbulence hence the channel refractive index under Qatar harsh environment and their influence on the hybrid FSO/RF availability. In this approach, either FSO/RF or simultaneous or none of them can be active. Based on soft switching approach and a finite state Markov Chain (FSMC) process, we model the channel fading for the two links and derive a mathematical expression for the outage probability of the hybrid system. Then, we evaluate the behavior of the hybrid FSO/RF under hazy and harsh weather. Results show that the FSO/RF soft switching renders the system outage probability less than that of each link individually. A soft switching algorithm is being implemented on FPGAs using Raptor code interfaced to the two terminals of a 1Gbps/100 Mbps FSO/RF hybrid system, the first being implemented in the region. Experimental results are compared to the above simulation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20turbulence"
