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">74</span> Catch Composition and Amount of Illegal and Unreported Fishing in Iranian Coastal Waters - Hormozgan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasemi%20Mehran">Yasemi Mehran</a>, <a href="https://publications.waset.org/abstracts/search?q=Parsa%20Mehran"> Parsa Mehran</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzingohar%20Mehrnaz"> Farzingohar Mehrnaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Illegal, unreported, and unregulated (IUU) ﬁshing has been identiﬁed as one of the most serious threats to the sustainability of the world’s ﬁsheries. In the present study, illegal and unreported fishing of different species in waters of Persian Gulf and Oman Sea (Hormozgan province) were evaluated. Among 47 species of 33 families identified in this study, with 39 species belong to teleosts, 4 species belong to elasmobranchs and 4 species belong to invertebrate. The total weight of illegal and unreported catch were 78525.22 tonnes. Maximum and minimum values were found for Dussumiera acuta (20640.74 tonnes) and Tenualosa ilisha (0.733 tonnes), respectively. The most commercial species group was scombridae, carangidae and clupeidae, respectively. Teleosts with 91.15%, elasmobranchs with 4.82 and invertebrates with 4.03% constituted total weight of illegal and unreported fishing.

Regarding the threats faced by these forests and the declining area of them all over the world, as well as in Iran, it is very necessary to manage and monitor them. The current study aimed to investigate the changes in mangrove forests and the relationship between these changes and the marine hydrodynamics and coastal morphology in the area between qeshm island and the west coast of the Hormozgan province (i.e. the coastline between Mehran river and Bandar-e Pol port) in the 49-year period. After preprocessing and classifying satellite images using the SVM, MLC, and ANN classifiers and evaluating the accuracy of the maps, the SVM approach with the highest accuracy (the Kappa coefficient of 0.97 and overall accuracy of 98) was selected for preparing the classification map of all images. The results indicate that from 1972 to 1987, the area of these forests have had experienced a declining trend, and in the next years, their expansion was initiated. These forests include the mangrove forests of Khurkhuran wetland, Muriz Deraz Estuary, Haft Baram Estuary, the mangrove forest in the south of the Laft Port, and the mangrove forests between the Tabl Pier, Maleki Village, and Gevarzin Village. The marine hydrodynamic and geomorphological characteristics of the region, such as average intertidal zone, sediment data, the freshwater inlet of Mehran river, wave stability and calmness, topography and slope, as well as mangrove conservation projects make the further expansion of mangrove forests in this area possible. By providing significant and up-to-date information on the development and decline of mangrove forests in different parts of the coast, this study can significantly contribute to taking measures for the conservation and restoration of mangrove forests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mangrove%20forests" title="mangrove forests">mangrove forests</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20hydrodynamics" title=" marine hydrodynamics"> marine hydrodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20morphology" title=" coastal morphology"> coastal morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=west%20of%20strait%20of%20Hormuz" title=" west of strait of Hormuz"> west of strait of Hormuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/148851/impact-of-marine-hydrodynamics-and-coastal-morphology-on-changes-in-mangrove-forests-case-study-west-of-strait-of-hormuz-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148851.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">95</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">72</span> Simulation of Flow Patterns in Vertical Slot Fishway with Cylindrical Obstacles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Solimani%20Babarsad">Mohsen Solimani Babarsad</a>, <a href="https://publications.waset.org/abstracts/search?q=Payam%20Taheri"> Payam Taheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerical results of vertical slot fishways with and without cylinders study are presented.

This clay tablet contains orders and is considered a historical document of the humanitarian behaviour of the victorious army during the conquest of Babylon. Some believe that these laws are the first declaration of human rights in the ancient world. After the conquest of Babylon, Cyrus created laws that had never been seen anywhere in history. For this reason, in this article it has been tried to mention the human aspects and the reasons and grounds for the formation of such laws at that time. The origin of the creation of these progressive and humanitarian laws in the Cyrus cylinder should be sought in the cultural roots of civilization and his social and individual teachings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iran" title="Iran">Iran</a>, <a href="https://publications.waset.org/abstracts/search?q=cyrus" title=" cyrus"> cyrus</a>, <a href="https://publications.waset.org/abstracts/search?q=cyrus%20cylinder" title=" cyrus cylinder"> cyrus cylinder</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a> </p> <a href="https://publications.waset.org/abstracts/173009/cyrus-cylinder-a-law-for-his-future-time" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173009.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">96</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">70</span> Predicting the Areal Development of the City of Mashhad with the Automaton Fuzzy Cell Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Dizbadi">Mehran Dizbadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniyal%20Safarzadeh"> Daniyal Safarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Arastoo"> Behrooz Arastoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ansgar%20Brunn"> Ansgar Brunn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rapid and uncontrolled expansion of cities has led to unplanned aerial development.

Software development organizations are highly knowledge-intensive organizations especially in their Requirement Elicitation Process (REP). There are several problems regarding communicating and using the knowledge in REP such as misunderstanding, being out of scope, conflicting information and changes of requirements. All of these problems occurred in transmitting the requirements knowledge during REP. Several researches have been done in REP in order to solve the problem towards requirements. Knowledge Audit (KA) approaches were proposed in order to solve managing knowledge in human resources, financial, and manufacturing. There is lack of study applying the KA in requirements elicitation process.

ECG signals are often contaminated with noise such as baseline wander and muscle noise. As these signals have been widely used in clinical studies to detect heart diseases, it is essential to filter these noises. In this paper we compare performance of Wiener Filtering and Median Filtering methods to filter Additive White Gaussian (AWG) noise with the determined signal to noise ratio (SNR) ranging from 3 to 5 dB applied to long-term ECG recordings samples. Root mean square error (RMSE) and coefficient of determination (R2) between the filtered ECG and original ECG was used as the filter performance indicator. Experimental results show that Wiener filter has better noise filtering performance than Median filter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ECG%20noise%20filtering" title="ECG noise filtering">ECG noise filtering</a>, <a href="https://publications.waset.org/abstracts/search?q=Wiener%20filtering" title=" Wiener filtering"> Wiener filtering</a>, <a href="https://publications.waset.org/abstracts/search?q=median%20filtering" title=" median filtering"> median filtering</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20noise" title=" Gaussian noise"> Gaussian noise</a>, <a href="https://publications.waset.org/abstracts/search?q=filtering%20performance" title=" filtering performance"> filtering performance</a> </p> <a href="https://publications.waset.org/abstracts/9623/additive-white-gaussian-noise-filtering-from-ecg-by-wiener-filter-and-median-filter-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9623.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">529</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">66</span> Cholinesterase Inhibitory Indole Alkaloids from the Bark of Rauvolfia reflexa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Fadaeinasab">Mehran Fadaeinasab</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Basiri"> Alireza Basiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Yalda%20Kia"> Yalda Kia</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Karimian"> Hamed Karimian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hapipah%20Mohd%20Ali"> Hapipah Mohd Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Vikneswaran%20Murugaiyah"> Vikneswaran Murugaiyah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two new, rauvolfine C and 3- methyl-10,11-dimethoxyl-6- methoxycarbonyl- β- carboline, along with five known indole alkaloids, macusine B, vinorine, undulifoline, isoresrpiline and rescinnamine were isolated from the bark of Rauvolfia reflexa.

Rescinnamine, a dual inhibitor was found to be the most potent inhibitor among the isolated alkaloids against both AChE and butyrylcholinesterase (BChE). Molecular docking revealed that rescinnamine interacted differently on AChE and BChE, by means of hydrophobic interactions and hydrogen bonding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rauvolfia%20reflexa" title="Rauvolfia reflexa">Rauvolfia reflexa</a>, <a href="https://publications.waset.org/abstracts/search?q=indole%20alkaloids" title=" indole alkaloids"> indole alkaloids</a>, <a href="https://publications.waset.org/abstracts/search?q=acetylcholinesterase" title=" acetylcholinesterase"> acetylcholinesterase</a>, <a href="https://publications.waset.org/abstracts/search?q=butyrylcholinesterase" title=" butyrylcholinesterase"> butyrylcholinesterase</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a> </p> <a href="https://publications.waset.org/abstracts/30034/cholinesterase-inhibitory-indole-alkaloids-from-the-bark-of-rauvolfia-reflexa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30034.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">592</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">65</span> Biosynthesis of Silver-Phosphate Nanoparticles Using the Extracellular Polymeric Substance of Sporosarcina pasteurii</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadhosein%20Rahimi">Mohammadhosein Rahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Raouf%20Hosseini"> Mohammad Raouf Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Bakhshi"> Mehran Bakhshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Baghbanan"> Alireza Baghbanan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Silver ions (Ag<sup>+</sup>) and their compounds are consequentially toxic to microorganisms, showing biocidal effects on many species of bacteria.

In this research, a gas sealed detector of proportional counter type was made and then its various parameters were investigated. Some parameters are influential on their working conditions and one of these most important parameters is the internal pressure of the proportional gas-filled detector. In this experimental research, we produced software for examination and altering high voltage, registering data, and calculating efficiency. By this, we investigated different gas pressure effects on detector efficiency and proposed optimizing working conditions of this detector.

Creation of Mg(OH)2 barrier layer after pretreatment enhanced corrostion resistance as well as wettability of substrate surface. Characterization including Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) was conducted to detect the existence of this barrier layer. Surface roughness and wettability of substrate was evaluated using atomic force microscopy (AFM) and contact angle measurement respectively. It is found that magnesium treated by 1M NaOH for 30 min reveals higher corrosion resistance and lower water contact angle of substrate surface. In addition, this investigation indicates that pH value of SBF solution is strongly influenced by different time and concentration of alkaline pretreatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnesium" title="magnesium">magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=NaOH%20pretreatment" title=" NaOH pretreatment"> NaOH pretreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20resistance" title=" corrosion resistance"> corrosion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=wettability" title=" wettability"> wettability</a> </p> <a href="https://publications.waset.org/abstracts/14548/effects-of-alkaline-pretreatment-parameters-on-the-corrosion-resistance-and-wettability-of-magnesium-implant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14548.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">961</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">62</span> Climate Change as Wicked Problems towards Sustainable Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Padash">Amin Padash</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Khodaparast"> Mehran Khodaparast</a>, <a href="https://publications.waset.org/abstracts/search?q=Saadat%20Khodaparast"> Saadat Khodaparast</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as “Global Warming”. The ultimate goal of this paper is to determine how climate change affects the style of life and all of our activities. The paper focuses on what the effects of humans are on climate change and how communities can achieve sustainable development and use resources in a way that is good for the ecosystem and public.

The geometry of the problem is considered to be a triangular enclosure. ANSYS Fluent software is used for modeling and numerical solution. This study is for steady state. Four right-angled triangles with height to base ratios of 2, 1, 0.5 and 0.25 are considered. The behavior of various parameters related to its performance, including temperature distribution and velocity vectors are evaluated, and graphs for the Nusselt number have been drawn. Also, in this study, the effect of geometric shape of enclosure with different height-to-base ratios has been evaluated for three types of boundary conditions of winter, summer day and one another state. It can be concluded that as the bottom side temperature and ratio of base to height of the enclosure increases, the convective effects become more prominent and circulation happened. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enclosure" title="enclosure">enclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title=" natural convection"> natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20solution" title=" numerical solution"> numerical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=Nusselt%20number" title=" Nusselt number"> Nusselt number</a>, <a href="https://publications.waset.org/abstracts/search?q=triangular" title=" triangular"> triangular</a> </p> <a href="https://publications.waset.org/abstracts/113867/numerical-study-of-natural-convection-in-a-triangular-enclosure-as-an-attic-for-different-geometries-and-boundary-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113867.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">197</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">60</span> Contemplation on Non-Expensive Housing Conception by Stable Approach in Metropolises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdieh%20Omranian">Mahdieh Omranian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Ghanbari%20Motlagh"> Mehran Ghanbari Motlagh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As we know, today urban growth, development, and intelligent social evolutions have been proposed in metropolises and this matter extends urban life which can have negative items besides positive and strong items.

Due to this popularity, computer softwares are being developed to generate and solve Sudoku puzzles with different levels of difficulty. Several methods and algorithms have been proposed and used in different softwares to efficiently solve Sudoku puzzles. Various search methods such as stochastic local search have been applied to this problem. Genetic Algorithm (GA) is one of the algorithms which have been applied to this problem in different forms and in several works in the literature. In these works, chromosomes with little or no information were considered and obtained results were not promising. In this paper, we propose a new way of applying GA to this problem which uses more-informed chromosomes than other works in the literature. We optimize the parameters of our GA using puzzles with different levels of difficulty. Then we use the optimized values of the parameters to solve various puzzles and compare our results to another GA-based method for solving Sudoku puzzles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=solving%20Sudoku%20puzzles" title=" solving Sudoku puzzles"> solving Sudoku puzzles</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20local%20search" title=" stochastic local search"> stochastic local search</a> </p> <a href="https://publications.waset.org/abstracts/8411/a-retrievable-genetic-algorithm-for-efficient-solving-of-sudoku-puzzles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8411.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">423</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">57</span> Effect of Submerged Water Jet's Cross Section Shapes on Mixing Length</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Solimani%20Babarsad">Mohsen Solimani Babarsad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Rastgoo"> Mohammad Rastgoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Payam%20Taheri"> Payam Taheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the important applications of hydraulic jets is used for discharge industrial, agricultural and urban wastewater into the rivers or other ambient water to reduce negative effects of pollutant water.

This study is conducted to investigate the distribution and length of the mixing zone in hydraulic jet's flow field with change in cross section shapes of nozzle. Toward this end, three shapes of cross section (square, circle and rectangular) and three saline densities current with different concentration are considered in a flume with 600 cm as long, 100 cm as high and 150 cm in width. Various discharges were used to evaluate mixing length for a wide range of densimetric Froude numbers, Frd, from 100 to 550 that is defined at the nozzle. Consequently, the circular nozzle, in comparison with other sections, has a densimetric Froude number 11% higher than square nozzle and 26% higher than rectangular nozzle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20jet" title="hydraulic jet">hydraulic jet</a>, <a href="https://publications.waset.org/abstracts/search?q=mixing%20zone" title=" mixing zone"> mixing zone</a>, <a href="https://publications.waset.org/abstracts/search?q=densimetric%20Froude%20number" title=" densimetric Froude number"> densimetric Froude number</a>, <a href="https://publications.waset.org/abstracts/search?q=nozzle" title=" nozzle "> nozzle </a> </p> <a href="https://publications.waset.org/abstracts/9237/effect-of-submerged-water-jets-cross-section-shapes-on-mixing-length" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9237.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">363</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">56</span> Realistic Testing Procedure of Power Swing Blocking Function in Distance Relay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Razavi">Farzad Razavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Taheri"> Behrooz Taheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Parpaei"> Mohammad Parpaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Mohammadi%20Ghalesefidi"> Mehdi Mohammadi Ghalesefidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Siamak%20Zarei"> Siamak Zarei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As one of the major problems in protecting large-dimension power systems, power swing and its effect on distance have caused a lot of damages to energy transfer systems in many parts of the world. Therefore, power swing has gained attentions of many researchers, which has led to invention of different methods for power swing detection. Power swing detection algorithm is highly important in distance relay, but protection relays should have general requirements such as correct fault detection, response rate, and minimization of disturbances in a power system. To ensure meeting the requirements, protection relays need different tests during development, setup, maintenance, configuration, and troubleshooting steps. This paper covers power swing scheme of the modern numerical relay protection, 7sa522 to address the effect of the different fault types on the function of the power swing blocking. In this study, it was shown that the different fault types during power swing cause different time for unblocking distance relay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20swing" title="power swing">power swing</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20relay" title=" distance relay"> distance relay</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20protection" title=" power system protection"> power system protection</a>, <a href="https://publications.waset.org/abstracts/search?q=relay%20test" title=" relay test"> relay test</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20in%20power%20system" title=" transient in power system"> transient in power system</a> </p> <a href="https://publications.waset.org/abstracts/82234/realistic-testing-procedure-of-power-swing-blocking-function-in-distance-relay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82234.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">385</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">55</span> Sensitivity Analysis of Oil Spills Modeling with ADIOS II for Iranian Fields in Persian Gulf</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzingohar%20Mehrnaz">Farzingohar Mehrnaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasemi%20Mehran"> Yasemi Mehran</a>, <a href="https://publications.waset.org/abstracts/search?q=Esmaili%20Zinat"> Esmaili Zinat</a>, <a href="https://publications.waset.org/abstracts/search?q=Baharlouian%20Maedeh"> Baharlouian Maedeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aboozar (Ardeshir) and Bahregansar are the two important Iranian oilfields in Persian Gulf waters. The operation activities cause to create spills which impacted on the marine environment. Assumed spills are molded by ADIOS II (Automated Data Inquiry for Oil Spills) which is NOAA’s weathering oil software. Various atmospheric and marine data with different oil types are used for the modeling. Numerous scenarios for 100 bbls with mean daily air temperature and wind speed are input for 5 days. To find the model sensitivity in each setting, one parameter is changed, but the others stayed constant. In both fields, the evaporated and dispersed output values increased hence the remaining rate is reduced. The results clarified that wind speed first, second air temperature and finally oil type respectively were the most effective factors on the oil weathering process. The obtained results can help the emergency systems to predict the floating (dispersed and remained) volume spill in order to find the suitable cleanup tools and methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ADIOS" title="ADIOS">ADIOS</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20spill" title=" oil spill"> oil spill</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20analysis" title=" sensitivity analysis"> sensitivity analysis</a> </p> <a href="https://publications.waset.org/abstracts/46836/sensitivity-analysis-of-oil-spills-modeling-with-adios-ii-for-iranian-fields-in-persian-gulf" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46836.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">299</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">54</span> Hearing Aids Maintenance Training for Hearing-Impaired Preschool Children with the Help of Motion Graphic Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Mokhtarzadeh">M.

Due to Shandiz’s natural beauty, suitable climate, and its close proximity to Mashhad which is the largest city in the eastern half of the country, many people own second houses in this area. In addition to this, Shandiz hosts millions of visitors annually. Its economic role, which is parallel and complementary to Mashhad, has caused population growth, the increase of activities, and physical expansion, all of which exceed the city’s capacity. The aim of this descriptive and analytical study was to evaluate the impact of city expansion on the environment and aid in preventing further harm to the natural environment of this perimeter. Data were collected from population and housing statistics during a different period of time-based on GIS. Results show that the existence of an integrated environmental management system in order to coordinate development projects and the expansion of tourism programs that meet environmental conditions are necessary and achieving sustainable development with quality of life in this area without considering environmental limitations and capabilities cannot be sustained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=population%20growth" title="population growth">population growth</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20development" title=" physical development"> physical development</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact" title=" environmental impact"> environmental impact</a>, <a href="https://publications.waset.org/abstracts/search?q=Shandiz%20City" title=" Shandiz City "> Shandiz City </a> </p> <a href="https://publications.waset.org/abstracts/20016/a-review-of-the-environmental-impact-of-physical-expansion-of-shandiz-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20016.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">351</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">52</span> Paternal Postpartum Depression and Its Relationship to Maternal Depression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Abdollahi">Fatemeh Abdollahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Zarghami"> Mehran Zarghami</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamshid%20Yazdani%20Jarati"> Jamshid Yazdani Jarati</a>, <a href="https://publications.waset.org/abstracts/search?q=Mun-Sunn%20Lye"> Mun-Sunn Lye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fathers may be at risk of depression during the postpartum period. Some studies have been reported maternal depression is the key predictor of paternal postpartum depression (PPD). This study aimed to explore this association. Using a cross-sectional study design, 591 couples referring to primary health centers at 2-8 weeks postpartum (during 2017) were recruited. Couples screened for depression using Edinburgh Postnatal Depression Scale (EPDS). Data on socio-demographic characteristics and psychosocial factors was also gathered. Paternal PPD was analyzed in relation to maternal PPD and other related factors using multiple regressions. The prevalence of Paternal and maternal postpartum depression was 15.7% (93) and 31.8% (188), respectively. The regression model showed that there was increased risk of PPD in fathers whose wives experienced PPD [OR=1.15, (95%CI: 1.04-1.27)], who had a lower state of general health [OR=1.21, (95%CI: 1.11-1.33)], who experienced increased number of life events [OR=1.42, (95%CI: 1.01-1.2.00)], and who were at older age [OR=1.20, (95%CI: 1.05- 1.36)]. Also, there was a decreased risk of depression in fathers with more children compared with those with fewer children [OR=0.20, (95%CI: 0.07-0.53)]. Maternal PPD and psychosocial risk factors were the strong predictors of parental PPD. Being grown up in a family with two depressed parents are an important issue for children and needs futher research and attention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Father" title="Father">Father</a>, <a href="https://publications.waset.org/abstracts/search?q=Mother" title=" Mother"> Mother</a>, <a href="https://publications.waset.org/abstracts/search?q=Postpartum%20depression" title=" Postpartum depression"> Postpartum depression</a>, <a href="https://publications.waset.org/abstracts/search?q=Risk%20factors" title=" Risk factors"> Risk factors</a> </p> <a href="https://publications.waset.org/abstracts/124312/paternal-postpartum-depression-and-its-relationship-to-maternal-depression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124312.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">146</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">51</span> The Lived Experience of Siblings of Autistic Children; From the Private to Public Sphere</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kiana%20Taghikhan">Kiana Taghikhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shamim%20Sherafat"> Shamim Sherafat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Taheri"> Mostafa Taheri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although many people with autism spectrum disorder around the world face many problems and challenges, their conditions may unintentionally affect the lives of the people around them. In this research the experiences of siblings of autistic children have been investigated in both the public and private spheres of their lives. "Private sphere" includes the experiences of research participants in socializing with relatives and family, assignments and responsibilities, as well as how they spend their leisure time and lifestyle. The "public sphere" includes the experience of their presence in society, such as university, or workplace and any outdoor activities that could have been affected by their sibling’s disorder. The present research has been done using the qualitative research method and in-depth interview technique with siblings of autistic children. The sample population is 15 individuals who participated in the research theoretically and purposefully. Based on the findings, the private and social experiences of these individuals is very different compared to peers who do not have siblings with autism disorder in the family. The difference is to such an extent that causes them to separate and distance themselves from other members of the society, and depending on their special conditions, it can affect their goals and life opportunities such as job, marriage, having children, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title="autism spectrum disorder">autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=siblings" title=" siblings"> siblings</a>, <a href="https://publications.waset.org/abstracts/search?q=private%20sphere" title=" private sphere"> private sphere</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sphere" title=" public sphere"> public sphere</a> </p> <a href="https://publications.waset.org/abstracts/190021/the-lived-experience-of-siblings-of-autistic-children-from-the-private-to-public-sphere" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190021.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">30</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">50</span> Rating and Generating Sudoku Puzzles Based on Constraint Satisfaction Problems </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahare%20Fatemi">Bahare Fatemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mehran%20Kazemi"> Seyed Mehran Kazemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nazanin%20Mehrasa"> Nazanin Mehrasa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sudoku is a logic-based combinatorial puzzle game which people in different ages enjoy playing it. The challenging and addictive nature of this game has made it a ubiquitous game. Most magazines, newspapers, puzzle books, etc. publish lots of Sudoku puzzles every day. These puzzles often come in different levels of difficulty so that all people, from beginner to expert, can play the game and enjoy it. Generating puzzles with different levels of difficulty is a major concern of Sudoku designers. There are several works in the literature which propose ways of generating puzzles having a desirable level of difficulty. In this paper, we propose a method based on constraint satisfaction problems to evaluate the difficulty of the Sudoku puzzles. Then, we propose a hill climbing method to generate puzzles with different levels of difficulty. Whereas other methods are usually capable of generating puzzles with only few number of difficulty levels, our method can be used to generate puzzles with arbitrary number of different difficulty levels. We test our method by generating puzzles with different levels of difficulty and having a group of 15 people solve all the puzzles and recording the time they spend for each puzzle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constraint%20satisfaction%20problem" title="constraint satisfaction problem">constraint satisfaction problem</a>, <a href="https://publications.waset.org/abstracts/search?q=generating%20Sudoku%20puzzles" title=" generating Sudoku puzzles"> generating Sudoku puzzles</a>, <a href="https://publications.waset.org/abstracts/search?q=hill%20climbing" title=" hill climbing"> hill climbing</a> </p> <a href="https://publications.waset.org/abstracts/8625/rating-and-generating-sudoku-puzzles-based-on-constraint-satisfaction-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8625.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">402</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">49</span> Rauvolfine B Isolated from the Bark of Rauvolfia reflexa (Apocynaceae) Induces Apoptosis through Activation of Caspase-9 Coupled with S Phase Cell Cycle Arrest</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Fadaeinasab">Mehran Fadaeinasab</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Karimian"> Hamed Karimian</a>, <a href="https://publications.waset.org/abstracts/search?q=Najihah%20Mohd%20Hashim"> Najihah Mohd Hashim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hapipah%20Mohd%20Ali"> Hapipah Mohd Ali </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, three indole alkaloids namely; rauvolfine B, macusine B, and isoreserpiline have been isolated from the dichloromethane crude extract of Rauvolfia reflexa bark (Apocynaceae). The structural elucidation of the isolated compounds has been performed using spectral methods such as UV, IR, MS, 1D, and 2D NMR. Rauvolfine B showed anti proliferation activity on HCT-116 cancer cell line, its cytotoxicity induction was observed using MTT assay in eight different cell lines. Annexin-V is serving as a marker for apoptotic cells and the Annexin-V-FITC assay was carried out to observe the detection of cell-surface Phosphatidylserine (PS). Apoptosis was confirmed by using caspase-8 and -9 assays. Cell cycle arrest was also investigated using flowcytometric analysis. rauvolfine B had exhibited significantly higher cytotoxicity against HCT-116 cell line. The treatment significantly arrested HCT-116 cells in the S phase. Together, the results presented in this study demonstrated that rauvolfine B inhibited the proliferation of HCT-116 cells and programmed cell death followed by cell cycle arrest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apocynacea" title="apocynacea">apocynacea</a>, <a href="https://publications.waset.org/abstracts/search?q=indole%20alkaloid" title=" indole alkaloid"> indole alkaloid</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20cycle%20arrest" title=" cell cycle arrest"> cell cycle arrest</a> </p> <a href="https://publications.waset.org/abstracts/13403/rauvolfine-b-isolated-from-the-bark-of-rauvolfia-reflexa-apocynaceae-induces-apoptosis-through-activation-of-caspase-9-coupled-with-s-phase-cell-cycle-arrest" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13403.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">334</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">48</span> Cadmium Filter Cake of a Hydrometallurgical Zinc Smelter as a New Source for the Biological Synthesis of CdS Quantum Dots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Bakhshi">Mehran Bakhshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Raouf%20Hosseini"> Mohammad Raouf Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadhosein%20Rahimi"> Mohammadhosein Rahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cadmium sulfide nanoparticles were synthesized from the nickel-cadmium cake of a hydrometallurgical zinc producing plant and sodium sulfide as Cd<sup>2+</sup> and S<sup>-2</sup> sources, respectively. Also, the synthesis process was performed by using the secretions of <em>Bacillus licheniformis</em> as bio-surfactant. Initially, in order to obtain a cadmium rich solution, two following steps were carried out: 1) Alkaline leaching for the removal of zinc oxide from the cake, and 2) acidic leaching to dissolve cadmium from the remained solid residue. Afterward, the obtained CdSO<sub>4</sub> solution was used for the nanoparticle biosynthesis. Nanoparticles were characterized by the energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) to confirm the formation of CdS crystals with cubic structure. Also, transmission electron microscopy (TEM) was applied to determine the particle sizes which were in 2-10 nm range. Moreover, the presence of the protein containing bio-surfactants was approved by using infrared analysis (FTIR). In addition, the absorbance below 400 nm confirms quantum particles’ size. Finally, it was shown that valuable CdS quantum dots could be obtained from the industrial waste products via environment-friendly biological approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosynthesis" title="biosynthesis">biosynthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium%20cake" title=" cadmium cake"> cadmium cake</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium%20sulfide" title=" cadmium sulfide"> cadmium sulfide</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title=" nanoparticle"> nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20smelter" title=" zinc smelter"> zinc smelter</a> </p> <a href="https://publications.waset.org/abstracts/57442/cadmium-filter-cake-of-a-hydrometallurgical-zinc-smelter-as-a-new-source-for-the-biological-synthesis-of-cds-quantum-dots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57442.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">304</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">47</span> The Impact of Initiators on Fast Drying Traffic Marking Paint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Taheri">Maryam Taheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jahanfar"> Mehdi Jahanfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenji%20Ogino"> Kenji Ogino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fast drying traffic marking paint comprising a solvent-borne resin, a filler, a pigment and a solvent that is especially suitable for colder ambient (temperatures near freezing) applications, where waterborne traffic paint cannot be used. Acrylic resins based on methyl methacrylate, butyl acrylate, acrylic acid, and styrene were synthesized in different solvents using organic peroxide initiators such as peroxyester, peroxyketal, dialkylperoxide and azo. After polymerization, the molecular weight (Mw), polydispersity index= PDI (Mw/Mn), viscosity, total residual monomer and APHA color were evaluated and results of organic peroxide initiators (t- butyl and t-amyl derivatives) were also compared with the azo initiator. The Mw, PDI, viscosity, mass conversation and APHA color of resins with t-amyl derivatives of organic peroxide initiators are very proper. The results of the traffic marking paints test such as non-volatile matter, no- pick- up time, hiding power, resistance to wear and water resistance study that produced with these resins also confirm this. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20drying%20traffic%20marking%20paint" title="fast drying traffic marking paint">fast drying traffic marking paint</a>, <a href="https://publications.waset.org/abstracts/search?q=acrylic%20resin" title=" acrylic resin"> acrylic resin</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20peroxide%20initiator" title=" organic peroxide initiator"> organic peroxide initiator</a>, <a href="https://publications.waset.org/abstracts/search?q=peroxyester" title=" peroxyester"> peroxyester</a>, <a href="https://publications.waset.org/abstracts/search?q=peroxyketal" title=" peroxyketal"> peroxyketal</a>, <a href="https://publications.waset.org/abstracts/search?q=dialkylperoxide%20and%20azo%20initiator" title=" dialkylperoxide and azo initiator"> dialkylperoxide and azo initiator</a> </p> <a href="https://publications.waset.org/abstracts/82325/the-impact-of-initiators-on-fast-drying-traffic-marking-paint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82325.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">208</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">46</span> Reliability Analysis of Soil Liquefaction Based on Standard Penetration: A Case Study in Babol City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehran%20Naghizaderokni">Mehran Naghizaderokni</a>, <a href="https://publications.waset.org/abstracts/search?q=Asscar%20Janalizadechobbasty"> Asscar Janalizadechobbasty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are more probabilistic and deterministic liquefaction evaluation procedures in order to judge whether liquefaction will occur or not. A review of this approach reveals that there is a need for a comprehensive procedure that accounts for different sources of uncertainty in liquefaction evaluation. In fact, for the same set of input parameters, different methods provide different factors of safety and/or probabilities of liquefaction. To account for the different uncertainties, including both the model and measurement uncertainties, reliability analysis is necessary. This paper has obtained information from Standard Penetration Test (SPT) and some empirical approaches such as: Seed et al, Highway bridge of Japan approach to soil liquefaction, The Overseas Coastal Area Development Institute of Japan (OCDI) and reliability method to studying potential of liquefaction in soil of Babol city in the north of Iran are compared. Evaluation potential of liquefaction in soil of Babol city is an important issue since the soil of some area contains sand, seismic area, increasing level of underground waters and consequently saturation of soil; therefore, one of the most important goals of this paper is to gain suitable recognition of liquefaction potential and find the most appropriate procedure of evaluation liquefaction potential to decrease related damages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20analysis"
