Any effective project-oriented organization should institutionalize its project management processes in such a manner to yield the greatest possible profits. The aim of this paper is to study the relationship between the project management PMBOK guideline (Project Management Body of Knowledge) and simulation technology in project-oriented organizations. The methodology involves using five steps for applying these two tools aimed at enhancing project management processes in the Lorestan Gas Corporation, as one of the project-oriented organization. Results show the implementation of such management approach leads to a 5% performance improvement and using PMBOK can be instrumental in effective delay management. The implementation of the aforementioned improvement package was effective in improving the efficiency of organizational processes; in terms of optimizing the resource utilization that has manifested itself in resource losses and cost reductions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=project-orientation" title="project-orientation">project-orientation</a>, <a href="https://publications.waset.org/abstracts/search?q=processes" title=" processes"> processes</a>, <a href="https://publications.waset.org/abstracts/search?q=PMBOK" title=" PMBOK"> PMBOK</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=organization" title=" organization"> organization</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a> </p> <a href="https://publications.waset.org/abstracts/43309/a-study-on-how-to-improve-pmbok-project-management-body-of-knowledge-guidelines-performance-by-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43309.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">404</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">539</span> Removal of Samarium in Environmental Water Samples by Modified Yeast Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Homayon%20Ahmad%20Panahi">Homayon Ahmad Panahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mehdi%20Seyed%20Nejad"> Seyed Mehdi Seyed Nejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Moniri"> Elham Moniri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A novel bio-adsorbent is fabricated by attaching a cibacron blue to yeast cells.

In this paper, Geostudio 2018 was used for modeling and verification of the full-scale test embankments (TS1, TS2, and TS3), which were constructed to study the effectiveness of PVDs for accelerating the consolidation and dissipation of the excess pore-pressures resulting from fill placement at Bangkok airport. Different depths and scenarios were modeled and the results were compared and analyzed. Since the ultimate goal is attaining pre-determined settlement, the settlement curve under soil embankment was used for the investigation of the results. It was shown that nearly in all cases, the same results and efficiency might be obtained by partial depth installation of PVDs instead of complete full constant length installation. However, it should be mentioned that because of distinct soil characteristics of clay soils and layers properties of any project, further investigation of full-scale test embankments and modeling is needed prior to finalizing the ultimate design by competent geotechnical consultants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20penetration" title="partial penetration">partial penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=surcharge%20preloading" title=" surcharge preloading"> surcharge preloading</a>, <a href="https://publications.waset.org/abstracts/search?q=excess%20pore%20water%20pressure" title=" excess pore water pressure"> excess pore water pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok%20test%20embankments" title=" Bangkok test embankments"> Bangkok test embankments</a> </p> <a href="https://publications.waset.org/abstracts/143189/numerical-study-of-partial-penetration-of-pvds-in-soft-clay-soils-treatment-along-with-surcharge-preloading-bangkok-airport-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143189.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">207</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">537</span> Design of Collection and Transportation System of Municipal Solid Waste in Meshkinshahr City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Fataei">Ebrahim Fataei</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ali%20Hosseini"> Seyed Ali Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Arabi"> Zahra Arabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Habib%20farhadi"> Habib farhadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Aalipour%20Erdi"> Mehdi Aalipour Erdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seiied%20Taghi%20Seiied%20Safavian"> Seiied Taghi Seiied Safavian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid waste production is an integral part of human life and management of waste require full scientific approach and essential planning.

One of the realities in the national infrastructure projects is that since the primary stakeholders are state-affiliated, the delay factors of the projects have not been seriously taken into account despite the importance of on-time completion of projects. Project postponement has different economic and social consequences and leads to the technical and economic infeasibility of the infrastructure projects in the form of reduced productivity and exploitation capacity. The present study aimed at investigating delay factors of Iranian national infrastructure projects according to regulatory reports of the Plan and Budget Organization (BPO) of Iran. The present study scrutinized the influence of each of the factors that caused delays in national Iranian infrastructure projects according to the supervision reports of the planning and budget organization in 8 years. For this purpose, the study analyzed the information regarding the impact of 12 key delay factors causing delays in average 4867 projects per year in all provinces. The said factors were classified into the three groups of executive, credit, and financial and environmental-procurement factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delays" title="delays">delays</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure" title=" infrastructure"> infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=projects" title=" projects"> projects</a>, <a href="https://publications.waset.org/abstracts/search?q=regulatory" title=" regulatory"> regulatory</a> </p> <a href="https://publications.waset.org/abstracts/145815/statistical-analysis-of-the-main-causes-of-delay-factors-of-infrastructure-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145815.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">137</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">535</span> Xanthotoxin: A Plant Derived Furanocoumarin with Antipathogenic and Cytotoxic Activities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mehdi%20Razavi%20Khosroshahi">Seyed Mehdi Razavi Khosroshahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years a great deal of efforts has been made to find natural derivative compounds to replace it's with synthetic drugs, herbicides or pesticides for management of human health and agroecosystem programs. This process can lead to a reduction in environmental harmful effects of synthetic chemicals. Xanthotoxin, as a furanocoumarin compound, found in some genera of the Apiaceae family of plants. The current work focuses on some xanthotoxin cytotoxicity and antipathogenic activities. The results indicated that xanthotoxin showed strong cytotoxic effects against LNCaP cell line with the IC₅₀ value of 0.207 mg/ml in a dose-dependent manner. After treatments of the cell line with 0.1 mg/ml of the compound, the viability of the cells was reached to zero. The current study revealed that xanthotoxin displayed strong antifungal activity against human or plant pathogen fungi, Aspergillus fumigatus, Aspegillusn flavus and Fusarum graminearum with minimum inhibitory concentration values of 52-68 µg/ml.

Regarding the unrecoverable damages which may occur after a dam break phenomenon, analyzing dams’ break is absolutely essential. GOLESTAN dam is located in the western South of Mashhad city in Iran. GOLESTAN dam break might lead to severe problems due to adjacent tourist and entertainment areas. In this paper, a numerical code based on the finite volume method was applied for assessing the risk of GOLESTAN dam break. As to this issue, first, a canal with a triangular barrier was modeled so as to verify the capability of the concerned code. Comparing analytical, experimental and numerical results showed that water level in the model results is in a good agreement with the similar water level in the analytical solutions and experimental data. The results of dam break modeling are revealed that two of the bridges, that are PARTOIE and NAMAYESHGAH, located downstream in the flow direction, are at risk following the potential GOLESTAN dam break. Therefore, the required times to conduct the precautionary measures at bridges were calculated at about 12 and 21 minutes, respectively. Thus, it is crucial to announce people about the possible risks of the dam break in order to decrease likely losses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20model" title="numerical model">numerical model</a>, <a href="https://publications.waset.org/abstracts/search?q=shallow%20water%20equations" title=" shallow water equations"> shallow water equations</a>, <a href="https://publications.waset.org/abstracts/search?q=GOLESTAN%20dam%20break" title=" GOLESTAN dam break"> GOLESTAN dam break</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20and%20wet%20beds%20modeling" title=" dry and wet beds modeling"> dry and wet beds modeling</a> </p> <a href="https://publications.waset.org/abstracts/96719/assessment-of-golestan-dam-break-using-finite-volume-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96719.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">144</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">533</span> Modelling Kinetics of Colour Degradation in American Pokeweed (Phytolacca americana) Extract Concentration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed-Ahmad%20Shahidi">Seyed-Ahmad Shahidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Salemeh%20Kazemzadeh"> Salemeh Kazemzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Sharifi%20Soltani"> Mehdi Sharifi Soltani</a>, <a href="https://publications.waset.org/abstracts/search?q=Azade%20Ghorbani-HasanSaraei"> Azade Ghorbani-HasanSaraei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The kinetics of colour changes of American Pokeweed extract, due to concentration by various heating methods was studied. Three different heating/evaporation processes were employed for production of American Pokeweed extract concentrate. The American Pokeweed extract was concentrated to a final 40 °Brix from an initial °Brix of 4 by microwave heating, rotary vacuum evaporator and evaporating at atmospheric pressure. The final American Pokeweed extract concentration of 40 °Brix was achieved in 188, 216 and 320 min by using microwave, rotary vacuum and atmospheric heating processes, respectively. The colour change during concentration processes was investigated. Total colour differences, Hunter L, a and b parameters were used to estimate the extent of colour loss. All Hunter colour parameters decreased with time. The zero-order, first-order and a combined kinetics model were applied to the changes in colour parameters. All models were found to describe the L, a and b-data adequately. Results indicated that variation in TCD followed both first-order and combined kinetics models. This model implied that the colour formation and pigment destruction occurred during concentration processes of American Pokeweed extract. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=American%20pokeweed" title="American pokeweed">American pokeweed</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour"> colour</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a> </p> <a href="https://publications.waset.org/abstracts/36138/modelling-kinetics-of-colour-degradation-in-american-pokeweed-phytolacca-americana-extract-concentration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36138.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">498</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">532</span> Buckling Analysis of 2D Frames Using the Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this paper is to present the Modified Newmark Method of buckling analysis frame considering the effect of the axial load. The discussion will be restricted to plane frameworks containing a constant cross-section for each element. In addition, it is assumed that the frames are prevented from out-of-plane deflection. In this method, stiffness matrix of the structure is considered to be constant. The most important advantage of such a method is that it obtains both upper and lower critical loads. The advanced of the present method is fast convergence, ability to use computer simulations, and ability to model structures with semi-rigid support conditions using linear and rotational spring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buckling" title="buckling">buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=frame" title=" frame"> frame</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20newmark%20method" title=" modified newmark method"> modified newmark method</a> </p> <a href="https://publications.waset.org/abstracts/42638/buckling-analysis-of-2d-frames-using-the-modified-newmark-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42638.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">417</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">531</span> Flow Duration Curve Method to Evaluate Environmental Flow: Case Study of Gharasou River, Ardabil, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Fuladipanah">Mehdi Fuladipanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jorabloo"> Mehdi Jorabloo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water flow management is one of the most important parts of river engineering.

This system has been operated in one boy’s high school, one girl’s high school and one high school in deprived aria. Method: At the first step the students registered for using the system. It was not mandatory and not free. They participated in estimating depression scale, anxiety scale and clinical interview by online medical care system. During this estimation, we could find the existence and severity of depression and anxiety in each one of the participants, also we could find the consequent needs of each one, such as supportive therapy in mild depression or anxiety, need to visited by psychologist in moderate cases, need to visited by psychiatrist in moderate-severe cases, need to visited by psychiatrist and psychologist in severe cases and need to perform medical lab examination tests. The lab examination tests were performed on persons specified by the system. The lab examinations were included: serum level of vitamin D, serum level of vitamin B12, serum level of calcium, fasting blood sugar, HbA1c, thyroid function tests and CBC. All of the students were solely treated by vitamins or minerals therapy and/ or treatment of medical problem (such as hypothyroidism). After a few months, we came back to high schools and estimated the existence and severity of depression and anxiety in treated students. With comparing these results, the affectability of the system could be prof. Results: Totally, we operate this project in 1077 participants in 243 of participant, the lab examination test were performed. In girls high schools: the existence and severity of depression significantly deceased (P value= 0.018<0.05 & P value 0.004< 0.05), but results about anxiety was not significant. In boys high schools: the existence and severity of depression significantly decreased (P value= 0.023<0.05 & P value = 0.004< 0.05 & P value= 0.049< 0.05). In boys high schools: the existence and severity of anxiety significantly decreased (P value= 0.041<0.05 & P value = 0.046< 0.05 &) but in one high school results about anxiety was not significant. In high school in deprived area the students did not have any problem paying for participating in the project, but they could not pay for medical lab examination tests. Thus, operation of the system was not possible in deprived area without a sponsor. Conclusion: This online medical system was successful in creating medical and psychiatric profile without attending physician. It was successful in decreasing depression without using antidepressants, but it was partially successful in decreasing anxiety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=depression" title="depression">depression</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes" title=" diabetes"> diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20medicare" title=" online medicare"> online medicare</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20D%20deficiency" title=" vitamin D deficiency "> vitamin D deficiency </a> </p> <a href="https://publications.waset.org/abstracts/41098/results-of-operation-of-online-medical-care-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41098.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">325</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">528</span> Preparation and Quality Control of a New Radiolabelled Complex of Spion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Yousefnia">H.

The aim of this study was the preparation and quality control of 153Sm-DTPA-DA-SPION complex. Samarium-153 was produced by neutron irradiation of the enriched 152Sm2O3 in a research reactor for 5 d. For radiolabeling purposes, 8 mg of the ligand was added to the vial containing 153SmCl3 and the mixture was sonicated 30 min, while pH was adjusted to 7-8. The radiochemical purity of the complex was checked by the ITLC method using NH4OH:MeOH:H2O (0.2:2:4) as the mobile phase. This new radiolabeled complex was prepared with a radiochemical purity of higher than 98% in 30 min at the optimized condition. The complex was kept at room temperature and in human serum at 37 °C for 48 h, showed no loss of 153Sm from the complex. Considering all of these features, this new radiolabeled complex can be considered as a good therapeutic agent; however, further studies on its biological behavior are still needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iron%20nanoparticles" title="iron nanoparticles">iron nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=preparation" title=" preparation"> preparation</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20control" title=" quality control"> quality control</a>, <a href="https://publications.waset.org/abstracts/search?q=153Sm" title=" 153Sm "> 153Sm </a> </p> <a href="https://publications.waset.org/abstracts/34298/preparation-and-quality-control-of-a-new-radiolabelled-complex-of-spion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34298.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">330</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">527</span> Assessment of Genetic Diversity of Iranian Purslane (Portulaca Oleracea L.)

One of the most effective measures is to enhance the skid resistance of road surface. This research aims to study the intersection of one case in Ahwaz and the effect of increasing the skid resistance in reducing pedestrian injuries in accidents at intersections. In this research the device was developed to measure the coefficient of friction and tried the rules and practices of it have a high similarity with the Locked Wheel Trailer. This device includes a steel frame, wheels, hydration systems, and force gauge. The output of the device is that the force gauge registers. By investigate this data and applying the relationships relative surface coefficient of friction is obtained. Friction coefficient data for the current state and the state of the new pavement are obtained and plotted on the graphs based on the graphs we can compare the two situations and speed at the moment of collision between the two modes are compared. The results show that increasing the coefficient of friction to what extent can be effective on the severity and number of accidents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intersection" title="intersection">intersection</a>, <a href="https://publications.waset.org/abstracts/search?q=coefficient%20of%20friction" title=" coefficient of friction"> coefficient of friction</a>, <a href="https://publications.waset.org/abstracts/search?q=skid%20resistance" title=" skid resistance"> skid resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=locked%20wheels" title=" locked wheels"> locked wheels</a>, <a href="https://publications.waset.org/abstracts/search?q=accident" title=" accident"> accident</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrian" title=" pedestrian"> pedestrian</a> </p> <a href="https://publications.waset.org/abstracts/15397/investigation-of-the-role-of-friction-in-reducing-pedestrian-injuries-in-accidents-at-intersections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15397.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">328</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">523</span> Hydrological Method to Evaluate Environmental Flow: Case Study of Gharasou River, Ardabil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Fuladipanah">Mehdi Fuladipanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jorabloo"> Mehdi Jorabloo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water flow management is one of the most important parts of river engineering.

To maintain river at an acceptable ecological condition, minimum daily discharge of index Q95 is 0.7 m^3.s^-1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gharasou%20River" title="Gharasou River">Gharasou River</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20flow%20management" title=" water flow management"> water flow management</a>, <a href="https://publications.waset.org/abstracts/search?q=non-uniformity%20distribution" title=" non-uniformity distribution"> non-uniformity distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20flow%20requirement" title=" ecosystem flow requirement"> ecosystem flow requirement</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20alteration" title=" hydraulic alteration"> hydraulic alteration</a> </p> <a href="https://publications.waset.org/abstracts/22677/hydrological-method-to-evaluate-environmental-flow-case-study-of-gharasou-river-ardabil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22677.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">335</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">522</span> Effect of PMMA Shield on the Patient Dose Equivalent from Photoneutrons Produced by High Energy Medical Linacs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mehdi%20Hashemi">Seyed Mehdi Hashemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Raisali"> Gholamreza Raisali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Taheri"> Mehran Taheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the important problems of using high energy linacs at IMRT is the production of photoneutrons. Besides the clinically useful photon beams, high-energy photon beams from medical linacs produce secondary neutrons. These photoneutrons increase the patient dose and may cause secondary malignancies. The effect of the shield on the reduction of photoneutron dose equivalent produced by a high energy medical linac at the patient plane is investigated in this study. To determine the photoneutron dose equivalent received to the patient a Varian linac working at 18 MV photon mode investigated. Photoneutron dose equivalent measured with Polycarbonate films of 0.25 mm thick. PC films placed at distances of 0, 10, 20, and 50 cm from the center of X-ray field on the patient couch. The results show that by increasing the distance from the center of the X-ray beam towards the periphery, the photoneutron dose equivalent decreases rapidly for both open and shielded fields and that by inserting the shield in the path of the X-ray beam, the photoneutron dose equivalent was decreased obviously compared to open field. Results show the shield, significantly reduces photoneutron dose equivalent to the patient. Results can be readily generalized to other models of medical linacs. It may be concluded that using this kind of shield can help more safe, inexpensive and efficient employment of high energy linacs in radiotherapy and IMRT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photoneutron" title="photoneutron">photoneutron</a>, <a href="https://publications.waset.org/abstracts/search?q=Linac" title=" Linac"> Linac</a>, <a href="https://publications.waset.org/abstracts/search?q=PMMA%20shield" title=" PMMA shield"> PMMA shield</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalent%20dose" title=" equivalent dose"> equivalent dose</a> </p> <a href="https://publications.waset.org/abstracts/32830/effect-of-pmma-shield-on-the-patient-dose-equivalent-from-photoneutrons-produced-by-high-energy-medical-linacs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32830.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">493</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">521</span> Preparation and Characterization of Nanocrystalline Cellulose from Acacia mangium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Gharehkhani">Samira Gharehkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Farid%20Seyed%20Shirazi"> Seyed Farid Seyed Shirazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Gharehkhani"> Abdolreza Gharehkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hooman%20Yarmand"> Hooman Yarmand</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Badarudin"> Ahmad Badarudin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rushdan%20Ibrahim"> Rushdan Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Salim%20Newaz%20Kazi"> Salim Newaz Kazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanocrystalline cellulose (NCC) were prepared by acid hydrolysis and ultrasound treatment of bleached Acacia mangium fibers.

In order to gain more understanding of the microstructure evolution of reservoir rocks under stress a series of axisymmetric triaxial tests were performed on two different analogue rock samples. In-situ compression tests were coupled with high resolution micro-Computed Tomography to elucidate the changes in the pore/grain network of the rocks under pressurized conditions. Two outcrop sandstones were chosen in the current study representing a various cementation status of well-consolidated and weakly-consolidated granular system respectively. High resolution images were acquired while the rocks deformed in a purpose-built compression cell. A detailed analysis of the 3D images in each series of step-wise compression tests (up to the failure point) was conducted which includes the registration of the deformed specimen images with the reference pristine dry rock image. Digital Image Correlation (DIC) technique based on the intensity of the registered 3D subsets and particle tracking are utilized to map the displacement fields in each sample. The results suggest the complex architecture of the localized shear zone in well-cemented Bentheimer sandstone whereas for the weakly-consolidated Castlegate sandstone no discernible shear band could be observed even after macroscopic failure. Post-mortem imaging a sister plug from the friable rock upon undergoing continuous compression reveals signs of a shear band pattern. This suggests that for friable sandstones at small scales loading mode may affect the pattern of deformation. Prior to mechanical failure, the continuum digital image correlation approach can reasonably capture the kinematics of deformation. As failure occurs, however, discrete image correlation (i.e. particle tracking) reveals superiority in both tracking the grains as well as quantifying their kinematics (in terms of translations/rotations) with respect to any stage of compaction. An attempt was made to quantify the displacement field in compression using continuum Digital Image Correlation which is based on the reference and secondary image intensity correlation. Such approach has only been previously applied to unconsolidated granular systems under pressure. We are applying this technique to sandstones with various degrees of consolidation. Such element of novelty will set the results of this study apart from previous attempts to characterize the deformation pattern in consolidated sands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deformation%20mechanism" title="deformation mechanism">deformation mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement%20field" title=" displacement field"> displacement field</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20behavior" title=" shear behavior"> shear behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=triaxial%20compression" title=" triaxial compression"> triaxial compression</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20micro-CT" title=" X-ray micro-CT "> X-ray micro-CT </a> </p> <a href="https://publications.waset.org/abstracts/79118/characterization-of-anisotropic-deformation-in-sandstones-using-micro-computed-tomography-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79118.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">189</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">517</span> Stability of Composite Struts Using the Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is to examine the behavior of elastic stability of reinforced and composite concrete struts with axial loads.

The main drawback of experimental methods is confined and expensive survey of UV reactors features. In this study, a CFD model utilizing the eulerian-lagrangian framework is applied to analysis the disinfection performance of a closed conduit reactor which contains four UV lamps perpendicular to the flow. A discrete ordinates (DO) model was employed to evaluate the UV irradiance field. To investigate the importance of each of lamps on the inactivation performance, in addition to the reference model (with 4 bright lamps), several models with one or two bright lamps in various arrangements were considered. All results were reported in three inactivation kinetics. The results showed that the log inactivation of the two central bright lamps model was between 88-99 percent, close to the reference model results. Also, whatever the lamps are closer to the main flow region, they have more effect on microbial inactivation. The effect of some operational parameters such as water flow rate, inlet water temperature, and lamps power were also studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eulerian-Lagrangian%20framework" title="Eulerian-Lagrangian framework">Eulerian-Lagrangian framework</a>, <a href="https://publications.waset.org/abstracts/search?q=inactivation%20kinetics" title=" inactivation kinetics"> inactivation kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=log%20inactivation" title=" log inactivation"> log inactivation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20UV%20reactor" title=" water UV reactor"> water UV reactor</a> </p> <a href="https://publications.waset.org/abstracts/22323/numerical-simulation-of-ultraviolet-disinfection-in-a-water-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22323.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">251</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">515</span> Effect of Fuel Injection Discharge Curve and Injection Pressure on Upgrading Power and Combustion Parameters in HD Diesel Engine with CFD Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Chamehsara">Saeed Chamehsara</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mostafa%20Mirsalim"> Seyed Mostafa Mirsalim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Tajdari"> Mehdi Tajdari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of fuel injection discharge curve and injection pressure simultaneously for upgrading power of heavy duty diesel engine by simulation of combustion process in AVL-Fire software are discussed.

Injection pressure with respect to amount of injected fuel and nozzle hole diameter are changed. Injection pressure is calculated by an experimental equation which is for heavy duty diesel engines with common rail fuel injection system.

For 1000 bar injection pressure with 188 mg injected fuel and 3 mm nozzle hole diameter in compare with first state which is semi-triangular discharge curve with 139 mg injected fuel and 3 mm nozzle hole diameter, upgrading power is about 19% whereas the special change has not been observed in cylinder pressure. On the other hand, both the NOX emission and the Soot emission decreased about 30% and 6% respectively. Compared with first state, for 2000 bar injection pressure that injected fuel and nozzle diameter are 196 mg and 2.6 mm respectively, upgrading power is about 22% whereas cylinder pressure has been fixed and NOX emission and the Soot emissions are decreased 36% and 20%, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD%20simulation" title="CFD simulation">CFD simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=HD%20diesel%20engine" title=" HD diesel engine"> HD diesel engine</a>, <a href="https://publications.waset.org/abstracts/search?q=upgrading%20power" title=" upgrading power"> upgrading power</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20pressure" title=" injection pressure"> injection pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20injection%20discharge%20curve" title=" fuel injection discharge curve"> fuel injection discharge curve</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20process" title=" combustion process"> combustion process</a> </p> <a href="https://publications.waset.org/abstracts/14565/effect-of-fuel-injection-discharge-curve-and-injection-pressure-on-upgrading-power-and-combustion-parameters-in-hd-diesel-engine-with-cfd-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14565.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">523</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">514</span> Investigating Elastica and Post Buckling Behavior Columns Using the Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this article is to analyze the finite displacement of Columns by applying the Modified Newmark Method.

Even though these systems are not applicable individually, they are very suitable supplements for the traditional filtration systems. The amount of inactivated microorganisms is dependent on the air velocity, lamp power, fluence rate distribution, and also germicidal susceptibility of microorganisms. In this paper, these factors are investigated utilizing an air-microorganism two-phase numerical model. The eulerian-lagrangian method was used to have more detailed information on the history of each particle. The UVGI system was modeled in three steps including: 1) modeling the air flow, 2) modeling the discrete phase of particles, 3) modeling the UV intensity field, and 4) modeling the particle inactivation. The results from modeling different lamp arrangements and powers showed that the system functions better at more homogeneous irradiation distribution. Since increasing the air flow rate of the device results in increasing of particle inactivation rate, the optimal air velocity shall be adjusted in accordance with the microorganism production rate, and the air quality requirement using the curves represented in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=microorganism" title=" microorganism"> microorganism</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase%20flow" title=" two-phase flow"> two-phase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=ultraviolet%20germicidal%20irradiation" title=" ultraviolet germicidal irradiation"> ultraviolet germicidal irradiation</a> </p> <a href="https://publications.waset.org/abstracts/22321/numerical-study-of-uv-irradiation-effect-on-air-disinfection-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22321.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">329</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">511</span> Synergistic Effects of Hydrogen Sulfide and Melatonin in Alleviating Vanadium Toxicity in Solanum lycopersicum L.

Nevertheless, the precise nature of their involvement in defensive reactions remains uncertain. This study investigates the impact of the ML-H2S interaction on tomato plants exposed to vanadium (V) toxicity, focusing on synthesising secondary metabolites and V metal sequestration. The treatments applied in this study included a control (T1), V stress (T2), MT+V (T3), MT+H2S+V (T4), MT+hypotaurine (HT)+V (T5), and MT+H2S+HT+V (T6). These treatments were administered: MT (150 µM) as a foliar spray pre-treatment (3X), HT treatment (0.1 mM, an H2S scavenger) as root immersion for 12 hours as pre-treatments, and H2S (NaHS, 0.2 mM) and V (40 mg/L) treatments added to the Hoagland solution for 2 weeks. Results demonstrate that ML and H2S+ML treatments alleviate V toxicity by promoting the transcription of key genes (ANS, F3H, CHS, DFR, PAL, and CHI) involved in phenolic and anthocyanin biosynthesis. Moreover, they decreased V uptake and accumulation and enhanced the transcription of genes involved in glutathione and phytochelatin synthesis (GSH1, PCS, and ABC1), leading to V sequestration in roots and protection against V-induced damage. Additionally, ML and H2S+ML treatments optimize chlorophyll metabolism, and increase internal H2S levels, thereby promoting tomato growth under V stress. The combined treatment of ML+H2S shows superior effects compared to ML alone, suggesting synergistic/interactive effects between these two substances. Furthermore, inhibition of the beneficial impact of ML+H2S and ML treatments by HT, an H2S scavenger, underscores the significant involvement of H₂S in the signaling pathway activated by ML during V toxicity. Overall, these findings suggest that ML requires the presence of endogenous H₂S to mitigate V-induced adverse effects on tomato seedlings. <p class="card-text"><strong>Keywords:</strong> <a
