In principle, GAP intends to maintain the maximum capacity of the airport through the best possible allocation of the resources (gates) in order to reach the optimum outcome. The problem involves a wide range of dependent and independent resources and their limitations, which add to the complexity of GAP from both theoretical and practical perspective. In this study, GAP was mathematically formulated as a three-objective problem. The preliminary goal of multi-objective formulation was to address a higher number of objectives that can be simultaneously optimized and therefore increase the practical efficiency of the final solution. The problem is solved by applying the second version of Non-dominated Sorting Genetic Algorithm (NSGA-II). Results showed that the proposed mathematical model could address most of major criteria in the decision-making process in airport management in terms of minimizing both airport/airline cost and passenger walking distance time. Moreover, the proposed approach could properly find acceptable possible answers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airport%20management" title="airport management">airport management</a>, <a href="https://publications.waset.org/abstracts/search?q=gate%20assignment%20problem" title=" gate assignment problem"> gate assignment problem</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title=" mathematical modeling"> mathematical modeling</a>, <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=NSGA-II" title=" NSGA-II"> NSGA-II</a> </p> <a href="https://publications.waset.org/abstracts/63467/an-evolutionary-multi-objective-optimization-for-airport-gate-assignment-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63467.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">40</span> Designing an Aerodynamic Braking in Order to Increase Power and Speed of Braking System of Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Ahmadi">Hamidreza Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Abbasalizadeh"> Majid Abbasalizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghasem%20Yazdani"> Ghasem Yazdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Ahmadi"> Masoud Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper a special kind of aerodynamic system as a spoiler has been designed and tried to show effects of this devise on braking system of vehicle. Moreover, position of this spoiler has been considered in order to find optimum point from safety and highest rate of braking view for spoiler. Fluent software is our main tool to calculate rate of extra force that is produced by spoiler and this article has been tried to use various figures that are showed effects of spoiler at different speeds, angles and also heights. Other major points in this paper are static pressure of vehicle at different speed and statues. Undoubtedly, shape of spoiler would be very important, so in this investigation spoiler has been designed and proposed after a lot of simulation for different shape of spoiler. In the end, there is very important part as validation since these simulations must be validated by experimental way to prove our claims. In this case, a special kind of BMW has been simulated and results have been compared by experimental results that have been presented by BMW Company. Difference between simulation results and experimental results are very little and it could be a suitable validation for this project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drag%20force" title="drag force">drag force</a>, <a href="https://publications.waset.org/abstracts/search?q=down%20force" title=" down force"> down force</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle" title=" vehicle"> vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=spoiler" title=" spoiler"> spoiler</a> </p> <a href="https://publications.waset.org/abstracts/12431/designing-an-aerodynamic-braking-in-order-to-increase-power-and-speed-of-braking-system-of-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12431.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">337</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">39</span> Prediction of the Solubility of Benzoic Acid in Supercritical CO2 Using the PC-SAFT EoS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Bagheri">Hamidreza Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Shariati"> Alireza Shariati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are many difficulties in the purification of raw components and products. However, researchers are seeking better ways for purification. One of the recent methods is extraction using supercritical fluids. In this study, the phase equilibria of benzoic acid-supercritical carbon dioxide system were investigated. Regarding the phase equilibria of this system, the modeling of solid-supercritical fluid behavior was performed using the Perturbed-Chain Statistical Association Fluid Theory (PC-SAFT) and Peng-Robinson equations of state (PR EoS). For this purpose, five PC-SAFT EoS parameters for pure benzoic acid were obtained using its experimental vapor pressure. Benzoic acid has association sites and the behavior of the benzoic acid-supercritical fluid system was well-predicted using both equations of state, while the binary interaction parameter values for PR EoS were negative. Genetic algorithm, which is one of the most accurate global optimization algorithms, was also used to optimize the pure benzoic acid parameters and the binary interaction parameters. The AAD% value for the PC-SAFT EoS, were 0.22 for the carbon dioxide-benzoic acid system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supercritical%20fluids" title="supercritical fluids">supercritical fluids</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility" title=" solubility"> solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=solid" title=" solid"> solid</a>, <a href="https://publications.waset.org/abstracts/search?q=PC-SAFT%20EoS" title=" PC-SAFT EoS"> PC-SAFT EoS</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/4168/prediction-of-the-solubility-of-benzoic-acid-in-supercritical-co2-using-the-pc-saft-eos" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4168.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">521</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">38</span> ARIMA-GARCH, A Statistical Modeling for Epileptic Seizure Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salman%20Mohamadi">Salman Mohamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Ali%20Tayaranian%20Hosseini"> Seyed Mohammad Ali Tayaranian Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Amindavar"> Hamidreza Amindavar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we provide a procedure to analyze and model EEG (electroencephalogram) signal as a time series using ARIMA-GARCH to predict an epileptic attack. The heteroskedasticity of EEG signal is examined through the ARCH or GARCH, (Autore- gressive conditional heteroskedasticity, Generalized autoregressive conditional heteroskedasticity) test. The best ARIMA-GARCH model in AIC sense is utilized to measure the volatility of the EEG from epileptic canine subjects, to forecast the future values of EEG. ARIMA-only model can perform prediction, but the ARCH or GARCH model acting on the residuals of ARIMA attains a con- siderable improved forecast horizon. First, we estimate the best ARIMA model, then different orders of ARCH and GARCH modelings are surveyed to determine the best heteroskedastic model of the residuals of the mentioned ARIMA. Using the simulated conditional variance of selected ARCH or GARCH model, we suggest the procedure to predict the oncoming seizures. The results indicate that GARCH modeling determines the dynamic changes of variance well before the onset of seizure. It can be inferred that the prediction capability comes from the ability of the combined ARIMA-GARCH modeling to cover the heteroskedastic nature of EEG signal changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epileptic%20seizure%20prediction" title="epileptic seizure prediction ">epileptic seizure prediction </a>, <a href="https://publications.waset.org/abstracts/search?q=ARIMA" title=" ARIMA"> ARIMA</a>, <a href="https://publications.waset.org/abstracts/search?q=ARCH%20and%20GARCH%20modeling" title=" ARCH and GARCH modeling"> ARCH and GARCH modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=heteroskedasticity" title=" heteroskedasticity"> heteroskedasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a> </p> <a href="https://publications.waset.org/abstracts/59028/arima-garch-a-statistical-modeling-for-epileptic-seizure-prediction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59028.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">406</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">37</span> Transfer Rate of Organic Water Contaminants through a Passive Sampler Membrane of Polyethersulfone (PES) </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Sharifan">Hamidreza Sharifan</a>, <a href="https://publications.waset.org/abstracts/search?q=Audra%20Morse"> Audra Morse</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accurate assessments of contaminant concentrations based on traditional grab sampling methods are not always possible. Passive samplers offer an attractive alternative to traditional sampling methods that overcomes these limitations. The POCIS approach has been used as a screening tool for determining the presence/absence, possible sources and relative amounts of organic compounds at field sites. The objective for the present research is on mass transfer of five water contaminants (atrazine, caffeine, bentazon, ibuprofen, atenolol) through the Water Boundary Layer (WBL) and membrane. More specific objectives followed by establishing a relationship between the sampling rate and water solubility of the compounds, as well as comparing the molecular weight of the compounds and concentration of the compounds at the time of equilibrium. To determine whether water boundary layer effects transport rate through the membrane is another main objective in this paper. After GC mass analysis of compounds, regarding the WBL effect in this experiment, Sherwood number for the experimental tank developed. A close relationship between feed concentration of compound and sampling rate has been observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=passive%20sampler" title="passive sampler">passive sampler</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20contaminants" title=" water contaminants"> water contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=PES-transfer%20rate" title=" PES-transfer rate"> PES-transfer rate</a>, <a href="https://publications.waset.org/abstracts/search?q=contaminant%20concentrations" title=" contaminant concentrations"> contaminant concentrations</a> </p> <a href="https://publications.waset.org/abstracts/43320/transfer-rate-of-organic-water-contaminants-through-a-passive-sampler-membrane-of-polyethersulfone-pes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43320.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">455</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">36</span> Effect of Damping on Performance of Magnetostrictive Vibration Energy Harvester</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Ghodsi">Mojtaba Ghodsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Ziaifar"> Hamidreza Ziaifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Mohammadzaheri"> Morteza Mohammadzaheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Payam%20Soltani"> Payam Soltani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents an analytical model to estimate the harvested power from a Magnetostrictive cantilevered beam with tip excitation. Furthermore, the effects of internal and external damping on harvested power are investigated. The magnetostrictive material in this harvester is Galfenol. In comparison to other popular smart materials like Terfenol-D, Galfenol has higher strength and machinability. In this article, first, a mechanical model of the Euler-Bernoulli beam is employed to calculate the deflection of the harvester. Then, the magneto-mechanical equation of Galfenol is combined with Faraday's law to calculate the generated voltage of the Magnetostrictive cantilevered beam harvester. Finally, the beam model is incorporated in the aforementioned combination. The results show that a 30×8.5×1 mm Galfenol cantilever beam harvester with 80 turn pickup coil can generate up to 3.7 mV and 9 mW. Furthermore, sensitivity analysis made by Response Surface Method (RSM) shows that the harvested power is only sensitive to the internal damping coefficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20damping%20coefficient" title="internal damping coefficient">internal damping coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20damping%20coefficient" title=" external damping coefficient"> external damping coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=euler-bernoulli" title=" euler-bernoulli"> euler-bernoulli</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20harvester" title=" energy harvester"> energy harvester</a>, <a href="https://publications.waset.org/abstracts/search?q=galfenol" title=" galfenol"> galfenol</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetostrictive" title=" magnetostrictive"> magnetostrictive</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20method" title=" response surface method"> response surface method</a> </p> <a href="https://publications.waset.org/abstracts/118790/effect-of-damping-on-performance-of-magnetostrictive-vibration-energy-harvester" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118790.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">113</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">35</span> Survey the Effects of Climate in Traditional and Modern Architecture of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yousefali%20Ziari">Yousefali Ziari</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Joudaki"> Hamidreza Joudaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Humans have regularly been interacting with their environment, and have a close relation with their environment. House as a shelter which protects us against hot and cold weather and the other climatic occurrences in the environment has a close relation with climate. Before human could have access to the fossil fuels, preparing the comfort for the house was done by adjusting the building according to the climate conditions, and the help of natural resources. However after the man could access the fossil fuel, this way was forgotten, and caused much use of energy for heating & cooling. This research is trying to find some methods for designing suitable building that create comfort fitting with the zone by studying the climate condition of Arak city and as a result to find a way to reduce the use of energy and improving the design. So for the aim of this research we have used the statistics and information such as temperature, rain, wind and the approximate moisture from a period of 40 years from synoptic station of Arak. After specifying the climate of Arak by the use of effective temperature, Ulgi, Guni, Mahani and Ovenz indicator, we investigated the climate comfort conditions and the harmonious architecture with the climate and then some suggestion was given according to the climate situation of each month of the year and quality of human comfort according to this indicators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate" title="climate">climate</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture" title=" architecture"> architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20and%20modern%20architecture" title=" traditional and modern architecture"> traditional and modern architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=comfort%20indicator" title=" comfort indicator"> comfort indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=Arak%20city" title=" Arak city"> Arak city</a> </p> <a href="https://publications.waset.org/abstracts/31815/survey-the-effects-of-climate-in-traditional-and-modern-architecture-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31815.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">479</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">34</span> Analysis of Organizational Factors Effect on Performing Electronic Commerce Strategy: A Case Study of the Namakin Food Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hamidreza%20Hejazi%20Dehghani">Seyed Hamidreza Hejazi Dehghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Neda%20Khounsari"> Neda Khounsari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Quick growth of electronic commerce in developed countries means that developing nations must change in their commerce strategies fundamentally. Most organizations are aware of the impact of the Internet and e-Commerce on the future of their firm, and thus, they have to focus on organizational factors that have an effect on the deployment of an e-Commerce strategy. In this situation, it is essential to identify organizational factors such as the organizational culture, human resources, size, structure and product/service that impact an e-commerce strategy. Accordingly, this research specifies the effects of organizational factors on applying an e-commerce strategy in the Namakin food industry. The statistical population of this research is 95 managers and employees. Cochran's formula is used for determination of the sample size that is 77 of the statistical population. Also, SPSS and Smart PLS software were utilized for analyzing the collected data. The results of hypothesis testing show that organizational factors have positive and significant effects of applying an e-Commerce strategy.

To generate spark plasma, a high-voltage (7 kV) and high-frequency (75 kHz) source was used. Infectious wounds in the peritoneum of mice were divided into control and plasma-treated groups at random. The plasma-treated animals received plasma radiation every 4 days for 12 days, for 60 seconds each time. On the 15th day after the first session, the wound in the plasma-treated group had completely healed. The spectra of spark plasma emission and tissue properties were studied. The mechanical resistance of the wound healed in the plasma treatment group was considerably higher than in the control group (p<0.05), according to the findings. Furthermore, histological evidence suggests that wound re-epithelialization is faster in comparison to controls. Angiogenesis and fibrosis (collagen production) were also dramatically boosted in the plasma-treated group, whereas the stage of wound healing inflammation was significantly reduced. Plasma therapy accelerated wound healing by causing considerable wound constriction. The results of this investigation show that spark plasma has an influence on the treatment of infectious wounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infectious%20wounds" title="infectious wounds">infectious wounds</a>, <a href="https://publications.waset.org/abstracts/search?q=mice" title=" mice"> mice</a>, <a href="https://publications.waset.org/abstracts/search?q=spark%20plasma" title=" spark plasma"> spark plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/140938/the-effects-of-spark-plasma-on-infectious-wound-healing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140938.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">295</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">32</span> Microdosimetry in Biological Cells: A Monte Carlo Method </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Jabal%20Ameli">Hamidreza Jabal Ameli</a>, <a href="https://publications.waset.org/abstracts/search?q=Anahita%20Movahedi"> Anahita Movahedi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: In radionuclide therapy, radioactive atoms are coupled to monoclonal antibodies (mAbs) for treating cancer tumor while limiting radiation to healthy tissues. We know that tumoral and normal tissues are not equally sensitive to radiation. In fact, biological effects such as cellular repair processes or the presence of less radiosensitive cells such as hypoxic cells should be taken account. For this reason, in this paper, we want to calculate biological effect dose (BED) inside tumoral area and healthy cells around tumors. Methods: In this study, deposited doses of a radionuclide, gold-198, inside cells lattice and surrounding healthy tissues were calculated with Monte Carlo method. The elemental compositions and density of malignant and healthy tissues were obtained from ICRU Report 44. For reaching to real condition of oxygen effects, the necrosis and hypoxia area inside tumors has been assessed. Results: With regard to linear-quadratic expression which was defined in Monte Carlo, results showed that a large amount of BED is deposited in the well-oxygenated part of the hypoxia area compared to necrosis area. Moreover, there is a significant difference between the curves of absorbed dose with BED and without BED. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20dose" title="biological dose">biological dose</a>, <a href="https://publications.waset.org/abstracts/search?q=monte%20carlo" title=" monte carlo"> monte carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=hypoxia" title=" hypoxia"> hypoxia</a>, <a href="https://publications.waset.org/abstracts/search?q=radionuclide%20therapy" title=" radionuclide therapy"> radionuclide therapy</a> </p> <a href="https://publications.waset.org/abstracts/20538/microdosimetry-in-biological-cells-a-monte-carlo-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20538.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">487</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">31</span> Case Report: Clinical Improvement of Forbrain Neurologic Signs in 3- Month- Old Persian Mastiff Dog with Calvarial Hyperostosis Syndrome after Corticosteroid, Antiepileptic and Antibiotic Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Jahani">Hamidreza Jahani</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Salehzadeh"> Zahra Salehzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Amini"> Ehsan Amini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Tohidifar"> Mohsen Tohidifar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Calvarial Hyperostosis Syndrome (CHS) is a benign bone disease of the skull. It is a non-neoplastic and proliferative bone disease, and the main feature of the disease is progressive and asymmetrical bone involvement. CHS is mostly reported in young male and female bullmastiff dogs and less frequently in other breeds. The etiology of CHS is unknown. This is the first case report of CHS in Iran. A 3-month-old male Persian Mastiff was presented with chief complaints of multiple episodes of seizure, pacing, bizarre behavior, delayed growth, head pressing, and difficulty in opening the mouth. Central blindness and open fontanelles were observed in clinical examination. No abnormality was found in the complete blood count and routine blood biochemical tests. CT scan findings include cortical thickening of frontal and parietal bones and enlargement of the left retropharyngeal lymph node. For treatment, oral clindamycin for two weeks, prednisolone and phenobarbital for one month, respectively, were administrated, and the case showed improvement after a week and recovered after one month. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calvarial%20hyperostosis" title="calvarial hyperostosis">calvarial hyperostosis</a>, <a href="https://publications.waset.org/abstracts/search?q=Persian%20Mastiff" title=" Persian Mastiff"> Persian Mastiff</a>, <a href="https://publications.waset.org/abstracts/search?q=frontal%20bone" title=" frontal bone"> frontal bone</a>, <a href="https://publications.waset.org/abstracts/search?q=seizure" title=" seizure"> seizure</a> </p> <a href="https://publications.waset.org/abstracts/147402/case-report-clinical-improvement-of-forbrain-neurologic-signs-in-3-month-old-persian-mastiff-dog-with-calvarial-hyperostosis-syndrome-after-corticosteroid-antiepileptic-and-antibiotic-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147402.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">138</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">30</span> Modeling Pan Evaporation Using Intelligent Methods of ANN, LSSVM and Tree Model M5 (Case Study: Shahroud and Mayamey Stations)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Ghazvinian">Hamidreza Ghazvinian</a>, <a href="https://publications.waset.org/abstracts/search?q=Khosro%20Ghazvinian"> Khosro Ghazvinian</a>, <a href="https://publications.waset.org/abstracts/search?q=Touba%20Khodaiean"> Touba Khodaiean</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The importance of evaporation estimation in water resources and agricultural studies is undeniable. Pan evaporation are used as an indicator to determine the evaporation of lakes and reservoirs around the world due to the ease of interpreting its data. In this research, intelligent models were investigated in estimating pan evaporation on a daily basis. Shahroud and Mayamey were considered as the studied cities. These two cities are located in Semnan province in Iran. The mentioned cities have dry weather conditions that are susceptible to high evaporation potential. Meteorological data of 11 years of synoptic stations of Shahrood and Mayamey cities were used. The intelligent models used in this study are Artificial Neural Network (ANN), Least Squares Support Vector Machine (LSSVM), and M5 tree models.

This model is in light of blend hypothesis with erosion mechanics, in which multiphase hydrodynamics and geo-mechanics are coupled in a predictable way by means of principal unknowns, for example, saturation, pressure, porosity, and formation displacements. Foamy oil is demonstrated as a scattering of gas bubbles caught in the oil, where these gas air bubbles keep up a higher repository weight. A secluded methodology is then received to adequately exploit the current propelled standard supply and stress-strain codes. The model is actualized into three coordinated computational modules, i.e. erosion module, store module, and geo-mechanics module. The stress, stream and erosion mathematical statements are understood independently for every time addition, and the coupling terms (porosity, penetrability, plastic shear strain, and so on) are gone among them and iterated until certain union is accomplished on a period step premise. The framework is capable regarding its abilities, yet practical in terms of computer requirements and maintenance.

Antioxidant, for example L- Carnitine has beneficial effects in immune system and increased antioxidant enzymes activity. L- Carnitine protects the tissue against the oxidative side effect and helps the body to protect against stress during and after acute exercise. The aim of this study was to determine the effect of L-Carnitine on the blood enzymes: GPX SOD, CAT and GR response. In this study, 20 basketball players girls participated. Subjects were randomly assigned into two groups; placebo and supplementation. Antioxidadision enzymes (Superoxide Dismutase, Catalase, Glutathione Reductase, Glutathione Peroxidase) evaluated. L-Carnitine supplement group orally daily received 3000 mg powder for 14 dys. Then all participates trained basketball exercise acute. Blood samples were drawn vein before and immediately after exercise. Superoxide Dismutase, Catalase, Glutathione Reductase, Glutathione Peroxidase were measured, and data was analyzed using repeated measure ANOVA, Bonferroni and t-test. Our results showed: SOD, GPX and GPX (P < 0.05) have a significant increase. These results suggest L-Carnitine supplementation may increase GPX SOD, CAT, and basal anti oxidative capacity.

Most of the genomic signal processing methods is based on the period-3 characteristics of the nucleoids in DNA strands and consequently, spectral analysis is applied to the numerical sequences of DNA to find the location of periodical components. In this paper, a novel ensemble algorithm for gene selection in DNA sequences has been presented which is based on the combination of Goertzel algorithm and anti-notch filter (ANF). The proposed algorithm has many advantages when compared to other conventional methods. Firstly, it leads to identify the coding protein regions more accurate due to using the Goertzel algorithm which is tuned at the desired frequency. Secondly, faster detection time is achieved. The proposed algorithm is applied on several genes, including genes available in databases BG570 and HMR195 and their results are compared to other methods based on the nucleotide level evaluation criteria. Implementation results show the excellent performance of the proposed algorithm in identifying protein coding regions, specifically in identification of small-scale gene areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=protein%20coding%20regions" title="protein coding regions">protein coding regions</a>, <a href="https://publications.waset.org/abstracts/search?q=period-3" title=" period-3"> period-3</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-notch%20filter" title=" anti-notch filter"> anti-notch filter</a>, <a href="https://publications.waset.org/abstracts/search?q=Goertzel%20algorithm" title=" Goertzel algorithm"> Goertzel algorithm</a> </p> <a href="https://publications.waset.org/abstracts/10286/gene-prediction-in-dna-sequences-using-an-ensemble-algorithm-based-on-goertzel-algorithm-and-anti-notch-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10286.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">387</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">26</span> Effect of Conjugated Linoleic Acid on Lipid Metabolism and Increased Fat around the Muscle Durability by Reducing the Oxidation Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Khodaei">Hamidreza Khodaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Daryabeigi%20Zand"> Ali Daryabeigi Zand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conjugated linoleic acid (CLA) is a mixture of isomers of linoleic acid. Despite the fact that 28 different isomers of CLA have already been identified, but the main isomer found in natural diets more than ninety percent CLA on intake of food constitutes demonstrates. CLA is known to be a substance that readily available by rumen microorganisms in some ruminants such as cattle and sheep would likely be made. The main objective of this research was to evaluate the impacts of CLA on lipid metabolism and enhanced fat around the muscle durability by reducing the process of oxidation. In order to implement this research, 80 female mice of the Balb/C, with 55 days of age were employed in the experiment. Treatments include various levels of CLA. Over the course of this study blood samples was also taken from the tail vein of the studied mice. Some other relevant parameters such as serum concentrations of triglycerides, total cholesterol, LDL, HDL and liver enzymes were also determined. The oxidative stability of fats TBARS technique was investigated at different intervals. The findings of the research were analyzed by statistical software of SAS 98. The results, CLA had no significant effect on liver enzymes (P > 0.05). However, it showed a statistically significant impact on triglycerides and total cholesterol. Ratio of LDL to HDL declined remarkably. Histological studies demonstrated reduced accumulation of fat in the tissues surrounding muscles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conjugated%20linoleic%20acid" title="conjugated linoleic acid">conjugated linoleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=fat%20metabolism" title=" fat metabolism"> fat metabolism</a>, <a href="https://publications.waset.org/abstracts/search?q=fat%20retention" title=" fat retention"> fat retention</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidation%20process" title=" oxidation process"> oxidation process</a> </p> <a href="https://publications.waset.org/abstracts/75414/effect-of-conjugated-linoleic-acid-on-lipid-metabolism-and-increased-fat-around-the-muscle-durability-by-reducing-the-oxidation-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75414.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">198</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">25</span> Pain Control by Ketamine in Combat Situation; Consideration and Outcomes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Javad%20Behzadnia">Mohammad Javad Behzadnia</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Javadzadeh"> Hamidreza Javadzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Pain management is essential to surmounting multi-injured people in an overcrowded emergency setting. Its role would be more apparent when the physician encounters a mass casualty in a war zone or even a military prehospital. Having sedative and analgesic properties, rapid onset and offset effects, and maintaining the cardiovascular and respiratory contain are the main reason for selecting Ketamine as a good choice in the war zone. Methods: In a prospective interventional study in a war zone, we have selected and followed two groups of casualties for pain management. All were men with an average age of 26.6±8 y/o and 27.5 ±7 y/o in A and B groups, respectively. Group A received only Ketamine and Group B received Ketamine and diazepam. Results: This study showed that all of the injured patients who received Ketamine had experienced some agitation, and they may finally need benzodiazepines for sedation, but in group B that received benzodiazepine before or simultaneous with Ketamine, the agitation was significantly reduced. (P Value ≤0.05) Conclusion: Various factors may affect pain score and perception; patients' culture, mental health, previous drug usage, and addiction could alter the pain score in similar situations. It seems that the significant agitation is due to catecholamine release in stressful Moments of the battlefield. Accordingly, this situation could be exacerbated due to ketamine properties.

The number and position of the mints in each period reflects the amount of economic power, political security and business growth, which was always fluctuated its position with changing the political and economic condition. Considering that, trade has more growth during the Safavid period than previous ones, the mint also has been in greater importance. It seems the one hand, the growth of economic in Safavid period has a direct link with the number and places of the mints at that time and in the other hand, the mints have been formed in some places because of the specific characteristic of cities and regions. Increasing the number of mints in the north of the country due to the growth of silk trade and in the west and northwest due to the political and commercial relation with Ottoman Empire, also the characteristics such as existence of mines, located in the Silk Road and communication ways, all are the results of this investigation. Accordingly, in this article researcher tries to examine the characteristics that give priority to a city for having mint. With considering that in the various historical periods, the mints were based in the most important cities in terms of political and social, at that time, this article examines the cities specific characteristics in the formation of the mints in Safavid period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=documentary%20sources" title="documentary sources">documentary sources</a>, <a href="https://publications.waset.org/abstracts/search?q=coins" title=" coins"> coins</a>, <a href="https://publications.waset.org/abstracts/search?q=mint" title=" mint"> mint</a>, <a href="https://publications.waset.org/abstracts/search?q=city" title=" city"> city</a>, <a href="https://publications.waset.org/abstracts/search?q=Safavid" title=" Safavid"> Safavid</a> </p> <a href="https://publications.waset.org/abstracts/34824/evaluation-of-the-cities-specific-characteristics-in-the-formation-of-the-safavid-period-mints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34824.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">268</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">23</span> Relationship between the Ability of Accruals and Non-Systematic Risk of Shares for Companies Listed in Stock Exchange: Case Study, Tehran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lina%20Najafian">Lina Najafian</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Vakilifard"> Hamidreza Vakilifard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study focused on the relationship between the quality of accruals and non-systematic risk.

Most of these countries know this dynamic industry as main source of income, occupation, growth of private sector and development of infrastructure. One of the old methods of investment in countries such as Iran have transitional economy, is buying land and house, sometimes is resulted to high profit and of course for this reason hustler's are very interested in this background. Nowadays buying and selling land in the areas with pleasant climate in our country is considered. Since, Shahmirzad is a city with fair and desired environmental attractions is located in the border of deserted cities, mainly has special climatic position and these conditions are resulted to attraction of passenger, tourist for passing their leisure hours from Semnan and other cities of the area and from other provinces in hot seasons and with regard to these suitable conditions in the city buying land and housing also have been considered by most of residents of Semnan and cities around Shahmirzad by now. The aim of present research is investigation the role of tourism in increasing price of land and housing in Shahmirzad city. By studying on price of land and housing especially in central area, that gardens of the city are located in this area, we have concluded that role of tourism have caused in price of land and housing specially these prices in central and old areas are more expensive than towns around the city. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tourism" title="tourism">tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20conditions" title=" climate conditions"> climate conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=price%20of%20land%20and%20housing" title=" price of land and housing"> price of land and housing</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahmirzad" title=" Shahmirzad "> Shahmirzad </a> </p> <a href="https://publications.waset.org/abstracts/11698/role-of-tourism-in-increasing-of-price-of-land-and-housing-in-iran-case-study-of-shahmirzad-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11698.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">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Comparison of Early Silicon Oil Removal and Late Silicon Oil Removal in Patients With Rhegmatogenous Retinal Detachment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Torabi">Hamidreza Torabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Moghtaderi"> Mohsen Moghtaderi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Currently, deep vitrectomy with silicone oil tamponade is the standard treatment method for patients with Rhegmatogenous Retinal Detachment (RRD). After retinal repair, it is necessary to remove silicone oil from the eye, but the appropriate time to remove the oil and complications related to that time has been less studied. The aim of this study was to compare the results of the early removal of silicone oil with the delayed removal of silicone oil in patients with RRD. Method & material: Patients who were referred to the Ophthalmology Clinic of Baqiyatallah Hospital, Tehran, Iran, due to RRD with detached macula in 2021 & 2022 were evaluated. These patients were treated with deep vitrectomy and silicone oil tamponade. Patients whose retinas were attached after the passage of time were candidates for silicone oil removal (SOR) surgery. For patients in the early SOR group, SOR surgery was performed 3-6 months after the initial vitrectomy surgery, and for the late SOR group, SOR was performed after 6 months after the initial vitrectomy surgery. Results: In this study, 60 patients with RRD were evaluated. 23 (38.3%) patients were in the early group, and 37 (61.7%) patients were in the late group. Based on our findings, it was seen that the mean visual acuity of patients based on the Snellen chart in the early group (0.48 ± 0.23 Decimal) was better than the late group (0.33 ± 0.18 Decimal) (P-value=0.009). Retinal re-detachment has happened only in one patient with early SOR. Conclusion: Early removal of silicone oil (less than 6 months) from the eyes of patients undergoing RRD surgery has been associated with better vision results compared to late removal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=retinal%20detachment" title="retinal detachment">retinal detachment</a>, <a href="https://publications.waset.org/abstracts/search?q=vitrectomy" title=" vitrectomy"> vitrectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=silicone%20oil" title=" silicone oil"> silicone oil</a>, <a href="https://publications.waset.org/abstracts/search?q=silicone%20oil%20removal" title=" silicone oil removal"> silicone oil removal</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20acuity" title=" visual acuity"> visual acuity</a> </p> <a href="https://publications.waset.org/abstracts/165024/comparison-of-early-silicon-oil-removal-and-late-silicon-oil-removal-in-patients-with-rhegmatogenous-retinal-detachment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165024.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">77</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">20</span> Wheat Yield and Yield Components under Raised Bed Planting System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Miri">Hamidreza Miri</a>, <a href="https://publications.waset.org/abstracts/search?q=Farahnaz%20Momtazi"> Farahnaz Momtazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wheat is one of the most important crops in Fars province, and because of water shortage, there is a great emphasis on its water use efficiency in the production field. A field experiment was conducted in 2021 and 2022 in order to evaluate wheat yield and its components in raised planting system in Arsanjan, Fars province. The experiment was conducted as a split plot with three irrigation treatments (irrigation equal to evapotranspiration, 80% of evapotranspiration irrigation (moderate drought stress), and 60% of evapotranspiration irrigation (severe drought stress)) as the main plot and three planting methods (conventional flat planting, 60 cm raised bed planting and 120 cm raised bed planting) as a subplot. The results indicated that drought stress significantly decreased traits such as plant height, grain yield, ear number, seed number, and biological yield while increasing seed protein. Raised bed planting significantly increased the traits in comparison with conventional flat planting. So that plating with a 120 cm raised bed increased grain yield by 22.1% and 25.9% in the first and second years, respectively. This increase was 17% for biological, 75 for ear number, and 21% for seed number. Planting in raised bed system reduced the adverse effect of drought stress on wheat traits. In conclusion, based on the observed results planting in raised bed system can be adopted as an appropriate planting pattern for improving yield and water productivity in experimental regions and similar climates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wheat" title="wheat">wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=raised%20bed%20planting" title=" raised bed planting"> raised bed planting</a>, <a href="https://publications.waset.org/abstracts/search?q=drought%20stress" title=" drought stress"> drought stress</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20use" title=" water use"> water use</a> </p> <a href="https://publications.waset.org/abstracts/170384/wheat-yield-and-yield-components-under-raised-bed-planting-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170384.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">65</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">19</span> A Multi-Objective Gate Assignment Model Based on Airport Terminal Configuration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyedmirsajad%20Mokhtarimousavi">Seyedmirsajad Mokhtarimousavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Danial%20Talebi"> Danial Talebi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Asgari"> Hamidreza Asgari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assigning aircrafts’ activities to appropriate gates is one the most challenging issues in airport authorities’ multiple criteria decision making. The potential financial loss due to imbalances of demand and supply in congested airports, higher occupation rates of gates, and the existing restrictions to expand facilities provide further evidence for the need for an optimal supply allocation. Passengers walking distance, towing movements, extra fuel consumption (as a result of awaiting longer to taxi when taxi conflicts happen at the apron area), etc. are the major traditional components involved in GAP models. In particular, the total cost associated with gate assignment problem highly depends on the airport terminal layout. The study herein presents a well-elaborated literature review on the topic focusing on major concerns, applicable variables and objectives, as well as proposing a three-objective mathematical model for the gate assignment problem. The model has been tested under different concourse layouts in order to check its performance in different scenarios. Results revealed that terminal layout pattern is a significant parameter in airport and that the proposed model is capable of dealing with key constraints and objectives, which supports its practical usability for future decision making tools. Potential solution techniques were also suggested in this study for future works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airport%20management" title="airport management">airport management</a>, <a href="https://publications.waset.org/abstracts/search?q=terminal%20layout" title=" terminal layout"> terminal layout</a>, <a href="https://publications.waset.org/abstracts/search?q=gate%20assignment%20problem" title=" gate assignment problem"> gate assignment problem</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title=" mathematical modeling"> mathematical modeling</a> </p> <a href="https://publications.waset.org/abstracts/77708/a-multi-objective-gate-assignment-model-based-on-airport-terminal-configuration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77708.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">229</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Effect of Satureja khuzestanica Jamzad Supplementation on Inflammatory and Antioxidant Indicators in Type 2 Diabetes Patients: A Randomized Controlled Clinical Trial Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Bordbar">Maryam Bordbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaser%20Mokhayeri"> Yaser Mokhayeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20Roosta"> Sajjad Roosta</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Ghasemi"> Fatemeh Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Choobkar"> Saeed Choobkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Nikbakht"> Hamidreza Nikbakht</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Falahi"> Ebrahim Falahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Diabetes mellitus type 2 is the most common metabolic disorder that is growing exponentially worldwide. Satureja Khuzestanica Jamzad is a native plant of Iran that grows widely in the south of Iran. Its antimicrobial, antioxidant, anti-inflammatory and pain-relieving effects have been documented in animal studies. The purpose of this study is to investigate the effect of consumption daily S. khuzestanica on inflammatory and antioxidant indicators in type 2 diabetic patients. Methods and Materials: In a double-blind, placebo-controlled clinical trial, 67 patients with type 2 diabetes were included and divided into two groups. One group received S. khuzestanica (capsule containing 500 mg) and the other group received placebo (500 mg talcum powder) once a day for 12 weeks. After the intervention, the inflammatory and antioxidant indicators of the two groups were compared. Results: In comparison to placebo groups, there was a significant difference in levels of total antioxidant capacity, superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase; these antioxidant indicators were higher in the intervention group (P<0.05). Moreover, a considerable decrease in weight, CRP and IL-6 levels were observed in patients in the S.Khuzestanica group.

Two range-finding algorithms, namely time-of-flight and phase-shift, are evaluated for registration and supervisory control. The time-of-flight approach is implemented in a semi-field experiment to determine the precise position of a tiny retro-reflective moving object. The moving object simulates a surgical tool tip. The tool is a target that would be connected to the neuroArm end-effector during surgery inside the magnet bore of the MR imaging system. In order to apply flight approach, a 905-nm pulsed laser diode and an avalanche photodiode are utilized as the transmitter and receiver, respectively. For the experiment, a high frequency time to digital converter was designed using a field-programmable gate arrays. In the phase-shift approach, a continuous green laser beam with a wavelength of 530 nm was used as the transmitter. Results showed that a positioning error of 0.1 mm occurred when the scanner-target point distance was set in the range of 2.5 to 3 meters. The effectiveness of this non-contact approach exhibited that the method could be employed as an alternative for conventional mechanical registration arm. Furthermore, the approach is not limited by physical contact and extension of joint angles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20laser%20scanner" title="3D laser scanner">3D laser scanner</a>, <a href="https://publications.waset.org/abstracts/search?q=intraoperative%20MR%20imaging" title=" intraoperative MR imaging"> intraoperative MR imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroArm" title=" neuroArm"> neuroArm</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20registration" title=" real time registration"> real time registration</a>, <a href="https://publications.waset.org/abstracts/search?q=robot-assisted%20surgery" title=" robot-assisted surgery"> robot-assisted surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=supervisory%20control" title=" supervisory control"> supervisory control</a> </p> <a href="https://publications.waset.org/abstracts/70477/laser-registration-and-supervisory-control-of-neuroarm-robotic-surgical-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70477.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">286</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">16</span> Fabrication of Drug-Loaded Halloysite Nanotubes Containing Sodium Alginate/Gelatin Composite Scaffolds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masoumeh%20Haghbin%20Nazarpak">Masoumeh Haghbin Nazarpak</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Tolabi"> Hamidreza Tolabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aryan%20Ekhlasi"> Aryan Ekhlasi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bone defects are mentioned as one of the most challenging clinical conditions, affecting millions of people each year. A fracture, osteoporosis, tumor, or infection usually causes these defects. At present, autologous and allogeneic grafts are used to correct bone defects, but these grafts have some difficulties, such as limited access, infection, disease transmission, and immune rejection. Bone tissue engineering is considered a new strategy for repairing bone defects. However, problems with scaffolds’ design with unique structures limit their clinical applications. In addition, numerous in-vitro studies have been performed on the behavior of bone cells in two-dimensional environments. Still, cells grow in physiological situations in the human body in a three-dimensional environment. As a result, the controlled design of porous structures with high structural complexity and providing the necessary flexibility to meet specific needs in bone tissue repair is beneficial. For this purpose, a three-dimensional composite scaffold based on gelatin and sodium alginate hydrogels is used in this research. In addition, the antibacterial drug-loaded halloysite nanotubes were introduced into the hydrogel scaffold structure to provide a suitable substrate for controlled drug release. The presence of halloysite nanotubes improved hydrogel’s properties, while the drug eliminated infection and disease transmission. Finally, it can be acknowledged that the composite scaffold prepared in this study for bone tissue engineering seems promising. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=halloysite%20nanotubes" title="halloysite nanotubes">halloysite nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20tissue%20engineering" title=" bone tissue engineering"> bone tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20scaffold" title=" composite scaffold"> composite scaffold</a>, <a href="https://publications.waset.org/abstracts/search?q=controlled%20drug%20release" title=" controlled drug release"> controlled drug release</a> </p> <a href="https://publications.waset.org/abstracts/183072/fabrication-of-drug-loaded-halloysite-nanotubes-containing-sodium-alginategelatin-composite-scaffolds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183072.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">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Accuracy/Precision Evaluation of Excalibur I: A Neurosurgery-Specific Haptic Hand Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Hoshyarmanesh">Hamidreza Hoshyarmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Durante"> Benjamin Durante</a>, <a href="https://publications.waset.org/abstracts/search?q=Alex%20Irwin"> Alex Irwin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanju%20Lama"> Sanju Lama</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Zareinia"> Kourosh Zareinia</a>, <a href="https://publications.waset.org/abstracts/search?q=Garnette%20R.%20Sutherland"> Garnette R. Sutherland</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study reports on a proposed method to evaluate the accuracy and precision of Excalibur I, a neurosurgery-specific haptic hand controller, designed and developed at Project neuroArm. Having an efficient and successful robot-assisted telesurgery is considerably contingent on how accurate and precise a haptic hand controller (master/local robot) would be able to interpret the kinematic indices of motion, i.e., position and orientation, from the surgeon’s upper limp to the slave/remote robot. A proposed test rig is designed and manufactured according to standard ASTM F2554-10 to determine the accuracy and precision range of Excalibur I at four different locations within its workspace: central workspace, extreme forward, far left and far right. The test rig is metrologically characterized by a coordinate measuring machine (accuracy and repeatability < ± 5 µm). Only the serial linkage of the haptic device is examined due to the use of the Structural Length Index (SLI). The results indicate that accuracy decreases by moving from the workspace central area towards the borders of the workspace. In a comparative study, Excalibur I performs on par with the PHANToM PremiumTM 3.0 and more accurate/precise than the PHANToM PremiumTM 1.5. The error in Cartesian coordinate system shows a dominant component in one direction (δx, δy or δz) for the movements on horizontal, vertical and inclined surfaces. The average error magnitude of three attempts is recorded, considering all three error components. This research is the first promising step to quantify the kinematic performance of Excalibur I. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy" title="accuracy">accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20metrology" title=" advanced metrology"> advanced metrology</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20controller" title=" hand controller"> hand controller</a>, <a href="https://publications.waset.org/abstracts/search?q=precision" title=" precision"> precision</a>, <a href="https://publications.waset.org/abstracts/search?q=robot-assisted%20surgery" title=" robot-assisted surgery"> robot-assisted surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=tele-operation" title=" tele-operation"> tele-operation</a>, <a href="https://publications.waset.org/abstracts/search?q=workspace" title=" workspace"> workspace</a> </p> <a href="https://publications.waset.org/abstracts/86416/accuracyprecision-evaluation-of-excalibur-i-a-neurosurgery-specific-haptic-hand-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86416.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">336</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">14</span> Explaining the Role of Iran Health System in Polypharmacy among the Elderly</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Shati">Mohsen Shati</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyede%20Salehe%20Mortazavi"> Seyede Salehe Mortazavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Kazem%20Malakouti"> Seyed Kazem Malakouti</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Khanke%20Fazlollah%20Ahmadi"> Hamidreza Khanke Fazlollah Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Taking unnecessary or excessive medication or using drugs with no indication (polypharmacy) by people of all ages, especially the elderly, is associated with increased adverse drug reactions (ADR), medical errors, hospitalization and escalating the costs. It may be facilitated or impeded by the healthcare system. In this study, we are going to describe the role of the health system in the practice of polypharmacy in Iranian elderly. In this Inductive qualitative content analysis using Graneheim and Lundman methods, purposeful sample selection until saturation has been made. Participants have been selected from doctors, pharmacists, policy-makers and the elderly. A total of 25 persons (9 men and 16 women) have participated in this study. Data analysis after incorporating codes with similar characteristics revealed 14 subcategories and six main categories of the referral system, physicians’ accessibility, health data management, drug market, laws enforcement, and social protection. Some of the conditions of the healthcare system have given rise to polypharmacy in the elderly. In the absence of a comprehensive specialty and subspecialty referral system, patients may go to any physician office so may well be confused about numerous doctors' prescriptions. Electronic records not being prepared for the patients, failure to comply with laws, lack of robust enforcement for the existing laws and close surveillance are among the contributing factors. Inadequate insurance and supportive services are also evident. Age-specific care providing has not yet been institutionalized, while, inadequate specialist workforce playing a major role. So, one may not ignore the health system as contributing factor in designing effective interventions to fix the problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elderly" title="elderly">elderly</a>, <a href="https://publications.waset.org/abstracts/search?q=polypharmacy" title=" polypharmacy"> polypharmacy</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20system" title=" health system"> health system</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20study" title=" qualitative study"> qualitative study</a> </p> <a href="https://publications.waset.org/abstracts/95591/explaining-the-role-of-iran-health-system-in-polypharmacy-among-the-elderly" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95591.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">151</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">13</span> The Study of Seed Coating Effects on Germination Speed of Astragalus Adscendens under Different Moisture Conditions and Planting Depth in the Boroujerd Region</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Mehrabi">Hamidreza Mehrabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mandana%20Rezayee"> Mandana Rezayee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The coated seed process is from amplifier ways that stick various materials on the outer surface of the seeds that minimize the negative environmental effects and increase the ability of Plant establishment. This study was done to assess the effects of coated seed on the germination speed of Astragalus adscendens in different conditions of drought stress and planting depth as it was conducted with a completely randomized factorial design with four replications. treatments of covering material was used in Four non coating levels (NC), mineral-based coating (CC), organic - based coating (OC) hydro gel-based coating (HC) ; treatment of moisture percent used in three levels of dried soil content, treatments of planting depth in two surfaces of planting and three times of the seed diameter was 9%, 14% and 21 % respectively. During the test, it was evaluated the germination speed attribute. The main results showed that moisture treatments and planting depth at a surface of 1% (P <0/01) was significant and has no significant effect of treatment materials. Also, In examining of the interaction between type of covering material and soil moisture were not observed significant differences for germination speed between covering treatments and controls covering, but there was a significant difference between treatments in 9% and 21%. Although in examining the triple interaction, increasing moisture and planting depth enhanced the speed of germination process, but it was not significant statistically, while it has made important differences in terms of description; because it had not growth in the moisture level of 9% and shallow cultivation (high stress). However, treatment of covered materials growth has developed significantly, so it can be useful in enhancing plant performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seed%20coating" title="seed coating">seed coating</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20moisture" title=" soil moisture"> soil moisture</a>, <a href="https://publications.waset.org/abstracts/search?q=sowing%20depth" title=" sowing depth"> sowing depth</a>, <a href="https://publications.waset.org/abstracts/search?q=germination%20percentage" title=" germination percentage"> germination percentage</a> </p> <a href="https://publications.waset.org/abstracts/48322/the-study-of-seed-coating-effects-on-germination-speed-of-astragalus-adscendens-under-different-moisture-conditions-and-planting-depth-in-the-boroujerd-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48322.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">274</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">12</span> Effects of Conjugated Linoleic Acid (CLA) on Hormones and Factors Involved in Murine Ovulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Karshenas">Leila Karshenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Khodaei"> Hamidreza Khodaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Behnaz%20Mahdavi"> Behnaz Mahdavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ovulation is a physiologic process with an inflammatory response that depends on a coordinated activity of gonadotropins and steroid hormones, as well as inflammatory mediators such as cytokines, prostaglandins, leptin, nitric oxide (NO), etc. Conjugated linoleic acid (CLA) is composed of polyunsaturated fatty acids (PUFA) found in dairy products, beef and lamb. There is strong evidence that dietary CLA affects mediators involved in ovulation. The aim of this study was to determine the effects of different doses of dietary CLA on systemic and local hormones and factors involved in ovulation. In this case-control study, 80 (50±2-day old) female mice were randomly divided into four groups (C as the controls and T1, T2 and T3 as the treatment groups). There were four replicates in each group and there were five mice in every replicate (20 mice, in total). The mice in the control group were fed with no CLA in their diet but the ones in the treatment group received 0.1, 0.3 and 0.5g/kg of CLA (replacing corn oil in the diet), respectively for 120 days. Later on, blood samples were obtained from the tails of animals that displayed estrus signs and estradiol (E2), progesterone (P4), LH, FSH, NO, leptin and TNFα were measured. Furthermore, the effects of CLA on the ovarian production of prostaglandins (PGs) and NO were investigated. The data were analyzed by SAS software.CLA significantly decreased serum levels of FSH (p<0.05), LH, estradiol, NO, leptin and TNFα (p<0.01). In addition, CLA decreased progesterone levels but this effect was statistically insignificant. The significantly negative effects of CLA were seen on the ovarian production of PGE2 and PGF2α (p<0.01).It seems that CLA may play an effective role in reducing the ovulation rate in mice as CLA adversely affected female reproduction and it had negative effects on systemic and local hormones involved in ovulation. <p class="card-text"><strong>Keywords:</strong> <a
