Focus group discussions, participatory rural appraisal, interviewing local elderly people were conducted. Perceptions about climate change indicate that local people are experiencing impacts of climate change. According to local people, temperature, cyclone, rain, water-logging, siltation, salinity, erosion, and flash flood are increasing. Vulnerability assessment revealed that local people are variously affected by abnormal climate related disasters. This is jeopardizing their livelihoods, risking their lives, health, and their assets. This prevailing climatic situation in the area is also impacting their environmental conditions, biodiversity and natural resources, and their economic activities. The existing adaptation includes using traditional boat and mobile phone while fishing and making house on high land and lower height. Proposed adaptation for fishing boat are using more than 60 feet length with good timber, putting at least 3 longitudinal bar along upper side, using enough vertical side bars. The homestead measures include use of cross bracing of wall frame, roof tying with extra-post by ropes and plantation of timber tree against wind. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20level%20vulnerabilities" title="community level vulnerabilities">community level vulnerabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=Cox%E2%80%99s%20Bazar-Teknaf%20Coastal%20Area" title=" Cox’s Bazar-Teknaf Coastal Area"> Cox’s Bazar-Teknaf Coastal Area</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title=" Bangladesh"> Bangladesh</a> </p> <a href="https://publications.waset.org/abstracts/19015/community-level-vulnerabilities-to-climate-change-in-coxs-bazar-teknaf-coastal-area-of-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19015.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">537</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">22</span> Conservation of Sea Turtle in Cox’s Bazar- Teknaf Peninsula and Sonadia Island Ecologically Critical Area (ECA) of Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pronob%20Kumar%20Mozumder%20M.%20Nazrul%20Islam">Pronob Kumar Mozumder M.

Six species of marine turtle are found in the Indian Ocean. Among them, olive ridley (Lepidochelys olivacea) listed as endangered in the IUCN Red List of Threatened Species. Marine turtle populations in the Indian Ocean have been depleted through long-term exploitation of eggs and adults, incidental capture (fisheries bycatch) and many other sources of mortality. The specific objective of the study was to conserve the sea turtles specially the olive ridley (Lepidochelys olivacea) with a view to contribute towards protection of the turtle species from extinction and to facilitate hatching of eggs through providing protection to turtle eggs or nest through ex-situ conservation efforts. In order to achieve the desired outputs and success, a total of five turtle hatcheries were established at Pechardwip, Khurermukh, Hazompara, Bodormokam, and Sonadia Eastpara sites. In total, 31,853 eggs were collected from 260 nests and were transferred to five hatcheries. The number of eggs/nest varied from 38 to 190 with an average clutch size of 122 eggs/ nest. Hatching of eggs took place during January to June with a peak in April. Sea turtle eggs were incubated by metabolic heat and the heat of the sun. The incubation period of turtle eggs in Cox’s Bazar-Teknaf Peninsula and Sonadia Island ECAs extended from 54 to 75 days depending on the month with an average of 66 days. During study period the temperature in the ECAs varied between 10.5-34.5°C. A total of 27,937 hatchlings of turtle were produced from the five hatcheries and all the hatchlings produced were released into the sea. Hatching rates varied from 74-98 % depending on the location and months with an average of 88 %. Sea turtles spend the majority of their lives in the sea, only emerging on beaches to nest. Despite the intense conservation efforts on the beaches, some populations have still declined to the edge of extinction. So proper conservation and awareness measure should be taken for prevention of turtle extinction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conservation%20of%20sea%20turtle" title="conservation of sea turtle">conservation of sea turtle</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title=" Bangladesh"> Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=ecologically%20critical%20area" title=" ecologically critical area"> ecologically critical area</a>, <a href="https://publications.waset.org/abstracts/search?q=ECA" title=" ECA"> ECA</a>, <a href="https://publications.waset.org/abstracts/search?q=Lepidochelys%20olivacea" title=" Lepidochelys olivacea"> Lepidochelys olivacea</a> </p> <a href="https://publications.waset.org/abstracts/19016/conservation-of-sea-turtle-in-coxs-bazar-teknaf-peninsula-and-sonadia-island-ecologically-critical-area-eca-of-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19016.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">513</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">21</span> Endogeneity between Shari'ah Governance and Board Governance and Its Impact on Financial Stability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabur%20Mollah">Sabur Mollah</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Mobarek"> Asma Mobarek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to explore the endogenous relationship between Shari’ah governance and board governance for Islamic banks to identify complementary or substituting relationship between these governance parameters.

In this relationship, SSB and BoD complement each other. We also show that this complementary relationship between SSB and BoD helps enhance both management and asset quality, but mitigates capital adequacy, earnings, and liquidity in Islamic banks.

Development in Gilgit Baltistan has been challenging due to its geographical conditions and the human development indicators are lower than the rest of the Pakistan. Various socioeconomic factors are identified that play an important role in determining the choices and roles men and women undertake for contributing towards the labour force. Our research highlights the areas lagging behind in gender equality in the labour market. The availability and access of gender over these socioeconomic resources determine gender mainstreaming in the labour market. It is a need of time that gender gaps should be addressed at the grass root level by the policy makers to enhance the growth and improve human development indicators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20division%20of%20work" title="gender division of work">gender division of work</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20development" title=" human development"> human development</a>, <a href="https://publications.waset.org/abstracts/search?q=indicators%20of%20socioeconomic%20factors" title=" indicators of socioeconomic factors"> indicators of socioeconomic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=labour%20force" title=" labour force"> labour force</a> </p> <a href="https://publications.waset.org/abstracts/37835/a-gender-sensitive-labour-policy-for-gilgit-baltistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37835.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">355</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">18</span> Reduction of Rotor-Bearing-Support Finite Element Model through Substructuring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdur%20Rosyid">Abdur Rosyid</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20El-Madany"> Mohamed El-Madany</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohanad%20Alata"> Mohanad Alata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to simplicity and low cost, rotordynamic system is often modeled by using lumped parameters. Recently, finite elements have been used to model rotordynamic system as it offers higher accuracy. However, it involves high degrees of freedom. In some applications such as control design, this requires higher cost. For this reason, various model reduction methods have been proposed. This work demonstrates the quality of model reduction of rotor-bearing-support system through substructuring. The quality of the model reduction is evaluated by comparing some first natural frequencies, modal damping ratio, critical speeds and response of both the full system and the reduced system. The simulation shows that the substructuring is proven adequate to reduce finite element rotor model in the frequency range of interest as long as the numbers and the locations of master nodes are determined appropriately. However, the reduction is less accurate in an unstable or nearly-unstable system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rotordynamic" title="rotordynamic">rotordynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=timoshenko%20beam" title=" timoshenko beam"> timoshenko beam</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20solid%20elements" title=" 3D solid elements"> 3D solid elements</a>, <a href="https://publications.waset.org/abstracts/search?q=Guyan%20reduction%20method" title=" Guyan reduction method "> Guyan reduction method </a> </p> <a href="https://publications.waset.org/abstracts/2730/reduction-of-rotor-bearing-support-finite-element-model-through-substructuring" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2730.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">272</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">17</span> Mesoporous Carbon Ceramic SiO2/C Prepared by Sol-Gel Method and Modified with Cobalt Phthalocyanine and Used as an Electrochemical Sensor for Nitrite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdur%20Rahim">Abdur Rahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Lauro%20Tatsuo%20Kubota"> Lauro Tatsuo Kubota</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshitaka%20Gushikem"> Yoshitaka Gushikem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon ceramic mesoporous SiO2/50wt%C (SBET= 170 m2g-1), where C is graphite, was prepared by the sol gel method.

This study was conducted on a sample of 300 (6th through 10th-grade students) recruited from over ten schools in Dhaka. While the schools were selected purposively, the respondents within each school were selected conveniently. The collected data were analyzed using Pearson product-moment correlation, hierarchical regression, and simultaneous regression analysis. The results showed that psychological adjustment is positively correlated with paternal, maternal, teacher, and best friend acceptance. The paternal acceptance was significantly connected with maternal acceptance. The teacher and best friend acceptance are correlated substantially with paternal and maternal acceptance. The hierarchical multiple regressions indicated that maternal, paternal, teacher, and best friend acceptance-rejection contributed significantly to students' psychological adjustment. The results revealed substantial independent contributions of maternal, paternal, teacher, and best friend acceptance on the students' psychological adjustment. The simultaneous regression analysis indicates that the maternal and best friend acceptances (but not paternal acceptance) were significant predictors of psychological adjustments. It showed that 41.7% variability in psychological adjustment could be explained by paternal, maternal, and best friend acceptance. The findings of the present study are exciting. They may contribute to developing insight in parents and best friends for behaving properly with their offspring and friend, respectively, for better psychological adjustment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adjustment" title="adjustment">adjustment</a>, <a href="https://publications.waset.org/abstracts/search?q=parenting" title=" parenting"> parenting</a>, <a href="https://publications.waset.org/abstracts/search?q=rejection" title=" rejection"> rejection</a>, <a href="https://publications.waset.org/abstracts/search?q=acceptance" title=" acceptance"> acceptance</a> </p> <a href="https://publications.waset.org/abstracts/145696/relations-between-psychological-adjustment-and-perceived-parental-teacher-and-best-friend-acceptance-among-bangladeshi-adolescents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145696.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">145</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">15</span> An Empirical Study to Predict Myocardial Infarction Using K-Means and Hierarchical Clustering </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Minhazul%20%20%20Islam">Md.

The research explored the synthesis of chiral transition metal complexes containing these ligands and their applications in various asymmetric catalytic transformations. Herein, the transition metal complexes having ruthenium(II), rhodium(I) and iridium(I) metal centres will be discussed. These are air stable complexes and were characterized by CHN analysis, 1H, 13C, and 31P NMR spectroscopy, and polarimetry. Currently, there is an emphasis on 'greener' catalysts and the need for 'green' solvents in asymmetric catalysis. As such, the Ph-Garphos ligands were demethylated thereby introducing hydroxyl moieties unto the ligand scaffold. The facile tunability of the biaryl diphosphines led to the preparation of the (R)-(4,4',6,6'-tetrahydroxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (R-Ph-Garphos-OH), and (S)-(4,4',6,6'-tetrahydroxybiphenyl-2,2'-diyl)bis(diphenylphosphine) (S-Ph-Garphos-OH) ligands. These were successfully characterized by CHN analysis, 1H, 13C, and 31P NMR spectroscopy, and polarimetry. The use of the Ph-Garphos and Ph-Garphos-OH ligands and their transition metal complexes in asymmetric hydrogenations will be reported.

That is why to ensure safety of workers and population at plant site; Atmospheric dispersion modeling and radiation dose calculations were carried out for a hypothetical accidental release of airborne radionuclide from the 3 MW TRIGA research reactor of Savar, Bangladesh. It is designed with reactor core which consists of 100 fuel elements(1.82245 cm in diameter and 38.1 cm in length), arranged in an annular corefor steady-state and square wave power level of 3 MW (thermal) and for pulsing with maximum power level of 860MWth.The fuel is in the form of a uniform mixture of 20% uranium and 80% zirconium hydride. Total effective doses (TEDs) to the public at various downwind distances were evaluated with a health physics computer code “HotSpot” developed by Lawrence Livermore National Laboratory, USA. The doses were estimated at different Pasquill stability classes (categories A-F) with site-specific averaged meteorological conditions. The meteorological data, such as, average wind speed, frequency distribution of wind direction, etc. have also been analyzed based on the data collected near the reactor site.

The unique combination of soft phosphorus (P) and hard nitrogen (N) centres affords a variety of transition metal complexes as potential pre-catalysts for synthetically useful reactions. Herein three ligand systems will be reported; two bidentate ligands - (S)-8-(diphenyl-phosphino)-1,2,3,4-tetrahydronaphthalen-1-amine, (S)THNANH2, and (Rc)-1-((Sp)-2-diphenylphosphino) ferrocenylethylamine, (RcSp)PPFNH2 - and a tridentate (Rc)-1-((Sp)-2-diphenylphosphino) ferrocenylimino-pyridine, (RcSp)PPFNNH2 ligand; the latter prepared from the condensation of selected ferrocene aminophosphines with pyridine-2-carboxaldehyde. Suitable combinations of these aminophosphine ligands with ruthenium precursors have afforded highly efficient systems for the asymmetric hydrogenation and transfer hydrogenation of selected ketones in 2-propanol. The Ru-(S)THNANH2 precatalyst was the most efficient in the asymmetric hydrogenation of selected ketones with 100% conversions within 4 hours at a catalyst loading of 0.1 mol%. The Ru-(RcSp)PPFNNH2 precatalyst was the most efficient in the asymmetric transfer hydrogenation of the ketones with conversions as high as 98% with 0.1 mol% catalyst.

The newly installed NaI(Tl) detector has a circular lead shield of 22 mm width. An important consideration of any gamma-ray spectroscopy is the minimization of natural background radiation not originating from the radioactive sample that is being measured. Natural background gamma-ray radiation comes from naturally occurring or man-made radionuclides in the environment or from cosmic sources. Moreover, the main problem with this system is that it is not suitable for measurements of radioactivity with a large sample container like Petridish or Marinelli beaker geometry. When any laboratory installs a new detector or/and new shield, it “must” first carry out quality and performance tests for the detector and shield. This paper describes a new portable shielding system with lead that can reduce the background radiation. Intensity of gamma radiation after passing the shielding will be calculated using shielding equation I=Ioe-µx where Io is initial intensity of the gamma source, I is intensity after passing through the shield, µ is linear attenuation coefficient of the shielding material, and x is the thickness of the shielding material. The height and width of the shielding will be selected in order to accommodate the large sample container. The detector will be surrounded by a 4π-geometry low activity lead shield. An additional 1.5 mm thick shield of tin and 1 mm thick shield of copper covering the inner part of the lead shielding will be added in order to remove the presence of characteristic X-rays from the lead shield. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shield" title="shield">shield</a>, <a href="https://publications.waset.org/abstracts/search?q=NaI%20%28Tl%29%20detector" title=" NaI (Tl) detector"> NaI (Tl) detector</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20radiation" title=" gamma radiation"> gamma radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=intensity" title=" intensity"> intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20attenuation%20coefficient" title=" linear attenuation coefficient"> linear attenuation coefficient</a> </p> <a href="https://publications.waset.org/abstracts/146333/design-of-a-portable-shielding-system-for-a-newly-installed-naitl-detector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146333.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">158</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">10</span> Healthy, Breast Fed Bangladeshi Children Can Regulate Their Food Consumption in Each Meal and Feeding Duration When Offered with Varied Energy Density and Feeding Frequency of Complementary Foods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Munirul%20Islam">M.

We evaluated the effects of varied ED and FF of CFs on food intake and time required for child feeding during individual meals. During 9 separate, randomly ordered dietary periods lasting 3-6 days each, we measured self-determined intakes of porridges by 18 healthy, breastfed children 8-11 mo old who were fed coded porridges with energy densities of 0.5, 1.0 or 1.5 kcal/g, during 3, 4, or 5 meals/d. CF intake was measured by weighing the feeding bowl before and after every meal. Children consumed greater amounts of CFs per meal when they received diets with lower ED (p = 0.044) and fewer meals per day (p < 0.001). Food intake was less during the first meal of the day than the other meals. Greater time was expended per meal when fewer meals were offered. Time expended per meal did not vary by ED, but the children ate the lower ED diets faster (p = 0.019). Food intake velocity was also greater when more meals were offered per day (p = 0.005). These results provide further evidence of young children’s ability to regulate their energy intakes, even during infancy; and they convey information on factors that affect the amount of time that caregivers must devote to child feeding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complementary%20foods" title="complementary foods">complementary foods</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20density" title=" energy density"> energy density</a>, <a href="https://publications.waset.org/abstracts/search?q=feeding%20frequency" title=" feeding frequency"> feeding frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20children" title=" young children"> young children</a> </p> <a href="https://publications.waset.org/abstracts/34638/healthy-breast-fed-bangladeshi-children-can-regulate-their-food-consumption-in-each-meal-and-feeding-duration-when-offered-with-varied-energy-density-and-feeding-frequency-of-complementary-foods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34638.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">466</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">9</span> Effect of Site Amplification on Seismic Safety Evaluation of Flyover Pier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Raihan%20Mukhlis">Mohammad Raihan Mukhlis</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Abdur%20Rahman%20Bhuiyan"> M.

Being situated in a seismically active region, seismic safety evaluation of flyovers is essential for seismic risk reduction. Effects of site amplification on seismic safety evaluation of flyover piers are the main concern of this study. In this regard, failure mode, lateral strength and displacement ductility of piers of a typical multi-span simply supported flyover have been evaluated by Japan Road Association (JRA) recommended guidelines, with and without considering site amplification. Ultimate flexural strengths of piers have been computed using the pushover analysis results. Shear capacity of piers has been calculated using the guidelines of JRA. Lateral strengths have been determined depending on the failure modes of the piers. Displacement ductility of piers has been computed using yield and ultimate displacements of the piers obtained from the pushover analysis results. Selected earthquake time history is used in seismic safety evaluation of the flyover piers. Finally, the ductility design method is used to conduct the seismic safety evaluation of the piers with and without considering site amplification. From the numerical results, it has been revealed that the effects of site amplification on seismic safety evaluation of bridge structures should be carefully taken into account. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=displacement%20ductility" title="displacement ductility">displacement ductility</a>, <a href="https://publications.waset.org/abstracts/search?q=flyover%20pier" title=" flyover pier"> flyover pier</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20strength" title=" lateral strength"> lateral strength</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20evaluation" title=" safety evaluation"> safety evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20amplification" title=" site amplification"> site amplification</a> </p> <a href="https://publications.waset.org/abstracts/98971/effect-of-site-amplification-on-seismic-safety-evaluation-of-flyover-pier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98971.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">171</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">8</span> Analysis of Two-Phase Flow Instabilities in Conventional Channel of Nuclear Power Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Abdur%20Rashid%20Sarkar">M.

A two phase flow is susceptible to thermal-hydrodynamic instabilities, which may cause flow oscillations of constant amplitude or diverging amplitude. These oscillations may induce boiling crisis, disturb control systems, or cause mechanical damage. Based on their mechanisms, various types of instabilities can be classified for a nuclear reactor. From a practical engineering point of view one of the major design difficulties in dealing with multiphase flow is that the mass, momentum, and energy transfer rates and processes may be quite sensitive to the geometric configuration of the heat transfer surface. Moreover, the flow within each phase or component will clearly depend on that geometric configuration. The complexity of this two-way coupling presents a major challenge in the study of multiphase flows and there is much that remains to be done. Yet, the parametric effects on flow instability such as the effect of aspect ratio, pressure drop, channel length, its orientation inlet subcooling and surface roughness etc. have been analyzed. Another frequently occurring instability, known as the Kelvin–Helmholtz instability has been briefly reviewed. Various analytical techniques for predicting parametric effect on the instability are analyzed in terms of their applicability and accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two%20phase%20flows" title="two phase flows">two phase flows</a>, <a href="https://publications.waset.org/abstracts/search?q=boiling%20crisis" title=" boiling crisis"> boiling crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal-hydrodynamic%20instabilities" title=" thermal-hydrodynamic instabilities"> thermal-hydrodynamic instabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20cooled%20nuclear%20reactors" title=" water cooled nuclear reactors"> water cooled nuclear reactors</a>, <a href="https://publications.waset.org/abstracts/search?q=kelvin%E2%80%93helmholtz%20instability" title=" kelvin–helmholtz instability"> kelvin–helmholtz instability</a> </p> <a href="https://publications.waset.org/abstracts/40906/analysis-of-two-phase-flow-instabilities-in-conventional-channel-of-nuclear-power-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40906.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">397</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">7</span> Free, Fair, and Credible Election and Democratic Governance in Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Awal%20Hossain%20Mollah">Md.

Then, how far these elements have been ensured in Bangladeshi elections has been evaluated by analyzing all the national elections held since independence. Apart from these, major factors and challenges of holding a free, fair and credible election in Bangladesh have been examined through using the following research questions: 1. Does role of election commission matter for free, fair and credible elections to form a democratic government? 2. Does role of political parties matter for democratic governance? 3. Do role of government matter for conducting the free, fair and credible election in ensuring democratic governance? 4. Does non-party caretaker government matter for conducting a free, fair and credible election? 5. Does democratic governance depend on multi-dimensional factors and actors? Major findings of this study are: Since the independence of Bangladesh, 10 national elections held in various regimes. 4 out of 10 national elections have been found free, fair and credible which have been conducted by the non-party caretaker government. Rests of the elections are not out of controversy and full of manipulation held under elected government. However, the caretaker government has already been abolished by the AL government through 15th amendment of the constitution. The present AL government is elected by the 10th parliamentary election under incumbent (AL) government, but a major opposition allies (20 parties) lead by BNP boycotted this election and 154 of the total 300 seats being uncontested. As a result, AL again came to the power without a competitive election and most of the national and International election observers including media world consider this election as unfair and the government is suffering from lack of legitimacy. Therefore, the governance of present Bangladesh is not democratic at all and it is to be considered as one party (14 parties’ allies lead by AL) authoritarian governance in the shade of parliamentary governance. Both the position and opposition of the parliament is belonging in 14 parties’ alliances lead by AL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=democracy" title="democracy">democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=governance" title=" governance"> governance</a>, <a href="https://publications.waset.org/abstracts/search?q=free" title=" free"> free</a>, <a href="https://publications.waset.org/abstracts/search?q=fair%20and%20credible%20elections" title=" fair and credible elections"> fair and credible elections</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title=" Bangladesh"> Bangladesh</a> </p> <a href="https://publications.waset.org/abstracts/43065/free-fair-and-credible-election-and-democratic-governance-in-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43065.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">326</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">6</span> Production of Kudzu Starch Gels With Superior Mechanical and Rheological Properties Through Submerged Ethanol Exposure and Implications for in Vitro Digestion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John-Nelson%20Ekumah">John-Nelson Ekumah</a>, <a href="https://publications.waset.org/abstracts/search?q=Xu%20Han"> Xu Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiufang%20Liang"> Qiufang Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Benxi%20Wei"> Benxi Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Arif%20Rashid"> Arif Rashid</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Safiullah"> Muhammad Safiullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Qayum"> Abdul Qayum</a>, <a href="https://publications.waset.org/abstracts/search?q=Selorm%20Yao-Say%20Solomon%20Adade"> Selorm Yao-Say Solomon Adade</a>, <a href="https://publications.waset.org/abstracts/search?q=Nana%20Adwoa%20Nkuma%20Johnson"> Nana Adwoa Nkuma Johnson</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdur%20Rehman"> Abdur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaofeng%20Ren"> Xiaofeng Ren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Producing starch gels with superior mechanical attributes remains a challenging pursuit. This research sought to develop a simple method using ethanol exposure to produce robust starch gels. The gels’ mechanical properties, rheology, structural characteristics, and digestion were assessed through textural, rheological, structural, and in vitro digestion analyses. it investigation revealed an improvement in gel’s strength from 62.22 to178.82 g. The thermal transitions were accelerated when ethanol was elevated. The exposure to ethanol resulted in a reduction in syneresis from 11% to 9.5% over a period of 6 hours with noticeable change in size and color. Rheologically, the dominating storage modulus and tan delta (<0.55) emphasized the gel’s improved elasticity. X-ray analysis showed a stable B + V-type pattern after ethanol exposure, with increasing relative crystallinity to 7.9%. Digestibility revealed an ethanol induced resistance, through increased resistant starch from 1.87 to 8.73%. In general, the exposure to ethanol played a crucial role in enhancing the mechanical characteristics of kudzu starch gels, while simultaneously preserving higher levels of resistant starch fractions. These findings have wide-ranging implications in the fields of food and pharmaceuticals, underscoring the extensive academic and industrial importance of this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kudzu%20starch%20gels" title="kudzu starch gels">kudzu starch gels</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=rheological%20properties" title=" rheological properties"> rheological properties</a>, <a href="https://publications.waset.org/abstracts/search?q=submerged%20ethanol%20exposure" title=" submerged ethanol exposure"> submerged ethanol exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=In%20vitro%20digestion" title=" In vitro digestion"> In vitro digestion</a> </p> <a href="https://publications.waset.org/abstracts/188373/production-of-kudzu-starch-gels-with-superior-mechanical-and-rheological-properties-through-submerged-ethanol-exposure-and-implications-for-in-vitro-digestion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188373.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">38</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">5</span> Effect of Multi-Enzyme Supplementation on Growth Performance of Broiler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdur%20Rahman">Abdur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima"> Saima</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20N.%20Pasha"> T.

Supplementation of NSPs digesting enzymes may release the nutrients from feed and reduce the anti-nutritional effects of NSP’s. The present study was conducted to determine the effects of NSPs digesting enzymes (Zympex) in broiler chicks. A total of 120 day old broiler chicks (Hubbard) were categorized into 3 treatments and each treatment was having four replicates with 10 birds in each. Dietary treatments comprised of Basal diet (2740 KCal/Kg) as control-1 (T1), low energy diet (2630 KCal/kg) control-2 (T2) and low energy diet with 0.5 gm/Kg enzyme as T3. Multi-enzymes supplementation showed significant (P < 0.05) positive effect on weight gain (last three weeks), feed intake (last two weeks), FCR (1st, 2nd, 4th and 5th) and nutrient retention in T3 when compared with control-2. Weight gain was lower (P < 0.05) in low caloric feed group C when compared with control-1 in all weeks except last week (P > 0.05), feed consumption was significantly lower (P < 0.05) in 5th week and results showed significantly poor FCR (P < 0.05) in 2nd, 3rd and 4th week but non-significant effect in 1st and 5th week when compared with control-1 group, which revealed the positive effect of enzyme supplementation in low energy diet. These results revealed that enzyme supplementation releases more energy from low energy diets and results in equal performance to normal diet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20weight" title="body weight">body weight</a>, <a href="https://publications.waset.org/abstracts/search?q=FCR" title=" FCR"> FCR</a>, <a href="https://publications.waset.org/abstracts/search?q=feed%20intake" title=" feed intake"> feed intake</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme" title=" enzyme"> enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=non-starch%20polysaccharides" title=" non-starch polysaccharides"> non-starch polysaccharides</a> </p> <a href="https://publications.waset.org/abstracts/3817/effect-of-multi-enzyme-supplementation-on-growth-performance-of-broiler" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3817.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">349</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">4</span> Formulation and Evaluation of Piroxicam Hydrotropic Starch Gel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ghazwani">Mohammed Ghazwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Shyma%20Ali%20Alshahrani"> Shyma Ali Alshahrani</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Abdu%20Yousef"> Zahra Abdu Yousef</a>, <a href="https://publications.waset.org/abstracts/search?q=Taif%20Torki%20Asiri"> Taif Torki Asiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghofran%20Abdur%20Rahman"> Ghofran Abdur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Ali%20Alshahrani"> Asma Ali Alshahrani</a>, <a href="https://publications.waset.org/abstracts/search?q=Umme%20Hani"> Umme Hani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and introduction: Piroxicam is a nonsteroidal anti-inflammatory drug characterized by low solubility-high permeability used to reduce pain, swelling, and joint stiffness from arthritis. Hydrotropes are a class of compounds that normally increase the aqueous solubility of insoluble solutes. Aim: The objective of the present research study was to formulate and optimize Piroxicam hydrotropic starch gel using sodium salicylate, sodium benzoate as hydrotropic salts, and potato starch for topical application. Materials and methods: The prepared Piroxicam hydrotropic starch gel was characterized for various physicochemical parameters like drug content estimation, pH, tube extrudability, and spreadability; all the prepared formulations were subjected to in-vitro diffusion studies for six hours in 100 ml phosphate buffer (pH 7.4) and determined gel strength. Results: All formulations were found to be white opaque in appearance and have good homogeneity. The pH of formulations was found to be between 6.9-7.9. Drug content ranged from 96.8%-99.4.5%. Spreadability plays an important role in patient compliance and helps in the uniform application of gel to the skin as gels should spread easily; F4 showed a spreadability of 2.4cm highest among all other formulations. In in vitro diffusion studies, extrudability and gel strength were good with F4 in comparison with other formulations; hence F4 was selected as the optimized formulation. Conclusion: Isolated potato starch was successfully employed to prepare the gel. Hydrotropic salt sodium salicylate increased the solubility of Piroxicam and resulted in a stable gel, whereas the gel prepared using sodium benzoate changed its color after one week of preparation from white to light yellowish. Hydrotropic potato starch gel proposed a suitable vehicle for the topical delivery of Piroxicam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piroxicam" title="Piroxicam">Piroxicam</a>, <a href="https://publications.waset.org/abstracts/search?q=potato%20starch" title=" potato starch"> potato starch</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrotropic%20salts" title=" hydrotropic salts"> hydrotropic salts</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrotropic%20starch%20gel" title=" hydrotropic starch gel"> hydrotropic starch gel</a> </p> <a href="https://publications.waset.org/abstracts/157199/formulation-and-evaluation-of-piroxicam-hydrotropic-starch-gel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157199.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">145</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">3</span> Comparison of Small Ruminants (Sheep) Production Efficiency of Nomadic and Transhumance Flocks in Malakand, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akbar%20Nawaz%20Khan">Akbar Nawaz Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Ghaffar"> Abdul Ghaffar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdur%20Rehman"> Abdur Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naeem%20Riaz"> Muhammad Naeem Riaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Muhammad%20Hassan%20Andrabi"> Sayed Muhammad Hassan Andrabi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to compare sheep rearing in nomadic with transhumance system in term of production parameters. The following parameters which studied for comparison were household size, landholding area, flock size, body condition score, fecal egg count and live weight change in sheep under nomadic and transhumance systems of management in Malakand since October 2010 to March 2011. Further the effects of Body Condition Score (BCS) and Fecal Egg Count (FEC) on production were also examined. Two systems were checked for the purpose to check the efficiency of production. A total of eight flocks, four each from nomadic and transhumance system were selected for the study; each flock was divided into treatment and controlled groups to check the effect of treatment or de-wormers. A total of 160 animals were selected randomly (80 treated, 80 controlled). The adult ram average weight transhumance system was 55.58 kg while in nomadic that was 54.16 kg, weight change was positive, and the highest change was recorded in transhumance treated which was 13%. Fecal egg count was record low (75 EPG) in transhumance treated group while high (330 EPG) in nomadic controlled. Body condition score was recorded 3.6 for transhumance treated and 3.32 for nomadic treated. It is concluded from the present study that transhumance system performed significantly (p < 0.05) better in respect of live weight, BCS, FEC, family size, Landholding area, number of animals in a flock, offspring record, culling, and mortality. Mean values are 7.367 ± 0221, 0.900 ± 0.071, 63.167 ± 1.559, 55.600 ± 1.480, 8.300 ± 0.321 and 2.500 ± 0.158 respectively. De-wormer effect on FEC showed a significant reduction in egg load in mature sheep on both systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20ruminant" title="small ruminant">small ruminant</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep" title=" sheep"> sheep</a>, <a href="https://publications.waset.org/abstracts/search?q=nomadic" title=" nomadic"> nomadic</a>, <a href="https://publications.waset.org/abstracts/search?q=transhumance" title=" transhumance"> transhumance</a>, <a href="https://publications.waset.org/abstracts/search?q=Malakand" title=" Malakand"> Malakand</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20efficiency" title=" production efficiency"> production efficiency</a> </p> <a href="https://publications.waset.org/abstracts/85727/comparison-of-small-ruminants-sheep-production-efficiency-of-nomadic-and-transhumance-flocks-in-malakand-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85727.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">224</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">2</span> Impact of Social Crisis on Property Market Performance and Evolving Strategy for Improved Property Transactions in Crisis Prone Environment: A Case Study of North Eastern Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdur%20Raheem">Abdur Raheem</a>, <a href="https://publications.waset.org/abstracts/search?q=Ado%20Yakub"> Ado Yakub</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urban violence in the form of ethnic and religious conflicts have been on the increase in many African cities in the recent years of which most of them are the result of intense and bitter competition for political power, the control of limited economic, social and environmental resources. In Nigeria, the emergence of the Boko Haram insurgency in most parts of the north eastern parts have ignited violence, bloodshed, refuge exodus and internal migration. Not only do the persistent attacks of the sect create widespread insecurity and fear, it has also stifled normal processes of trade and investments most especially real property investment which is acclaimed to accelerate the economic cycle, thus the need to evolve strategies for an improved property market in such areas. This paper, therefore, examines the impact of these social crisis on effective and efficient utilization of real properties as a resource towards the development of the economy, using a descriptive analysis approach where particular emphasis was based on trends in residential housing values; volume of estimated property transactions and real estate investment decisions by affected individuals. Findings indicate that social crisis in the affected areas have been a clog on the wheels of property development and investment as properties worth hundreds of millions have been destroyed thereby having great impact on property values. Based on these findings, recommendations were made to include the need to strategically continue investing in property during such times, the need for Nigerian government to establish an active conflict monitoring and management unit for prompt response, encourage community and neighbourhood policing to ameliorate security challenges in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20crisis" title="social crisis">social crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=property%20market" title=" property market"> property market</a>, <a href="https://publications.waset.org/abstracts/search?q=economy" title=" economy"> economy</a>, <a href="https://publications.waset.org/abstracts/search?q=resources" title=" resources"> resources</a>, <a href="https://publications.waset.org/abstracts/search?q=north-eastern%20Nigeria" title=" north-eastern Nigeria"> north-eastern Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/63980/impact-of-social-crisis-on-property-market-performance-and-evolving-strategy-for-improved-property-transactions-in-crisis-prone-environment-a-case-study-of-north-eastern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63980.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">322</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">1</span> Quality Assurance Comparison of Map Check 2, Epid, and Gafchromic® EBT3 Film for IMRT Treatment Planning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Iqbal">Khalid Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Altaf"> Saima Altaf</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Akram"> M.

The purpose of this study was to test and compare various 2-D detectors for dosimetric quality assurance (QA) of intensity-modulated radiotherapy (IMRT) with the vision to find alternative QA methods. Material and Methods: Twenty IMRT patients (12 of brain and 8 of the prostate) were planned on Eclipse treatment planning system using Varian Clinac DHX on both energies 6MV and 15MV. Verification plans of all such patients were also made and delivered to Map check2, EPID (Electronic portal imaging device) and Gafchromic EBT3. Gamma index analyses were performed using different criteria to evaluate and compare the dosimetric results. Results: Statistical analysis shows the passing rate of 99.55%, 97.23% and 92.9% for 6MV and 99.53%, 98.3% and 94.85% for 15 MV energy using a criteria of ±5% of 3mm, ±3% of 3mm and ±3% of 2mm respectively for brain, whereas using ±5% of 3mm and ±3% of 3mm gamma evaluation criteria, the passing rate is 94.55% and 90.45% for 6MV and 95.25%9 and 95% for 15 MV energy for the case of prostate using EBT3 film. Map check 2 results shows the passing rates of 98.17%, 97.68% and 86.78% for 6MV energy and 94.87%,97.46% and 88.31% for 15 MV energy respectively for brain using a criteria of ±5% of 3mm, ±3% of 3mm and ±3% of 2mm, whereas using ±5% of 3mm and ±3% of 3mm gamma evaluation criteria gives the passing rate of 97.7% and 96.4% for 6MV and 98.75%9 and 98.05% for 15 MV energy for the case of prostate. EPID 6 MV and gamma analysis shows the passing rate of 99.56%, 98.63% and 98.4% for the brain, 100% and 99.9% for prostate using the same criteria as for map check 2 and EBT 3 film. Conclusion: The results demonstrate excellent passing rates were obtained for all dosimeter when compared with the planar dose distributions for 6 MV IMRT fields as well as for 15 MV. EPID results are better than EBT3 films and map check 2 because it is likely that part of this difference is real, and part is due to manhandling and different treatment set up verification which contributes dose distribution difference. Overall all three dosimeter exhibits results within limits according to AAPM report.120. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gafchromic%20EBT3" title="gafchromic EBT3">gafchromic EBT3</a>, <a href="https://publications.waset.org/abstracts/search?q=radiochromic%20film%20dosimetry" title=" radiochromic film dosimetry"> radiochromic film dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=IMRT%20verification" title=" IMRT verification"> IMRT verification</a>, <a href="https://publications.waset.org/abstracts/search?q=EPID" title=" EPID"> EPID</a> </p> <a href="https://publications.waset.org/abstracts/24288/quality-assurance-comparison-of-map-check-2-epid-and-gafchromic-ebt3-film-for-imrt-treatment-planning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24288.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">421</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
