Alloy layers formed by diffusion at both temperatures were investigated, and their features were compared with those of pack cementation aluminized steel. High-temperature oxidation tests were carried out in air at 600 °C for 145 hours. Results indicated that the aluminide coatings obtained from this process have significantly improved the high-temperature oxidation resistance in both methods due to the Al2O3 scale formation. Furthermore, it showed that the isothermal oxidation resistance of arc spray technique is better than pack cementation method. This can be attributed to voids that formed at the intermetallic layer /Al layer interface which is increased in the pack cementation method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20arc%20spray" title="electric arc spray">electric arc spray</a>, <a href="https://publications.waset.org/abstracts/search?q=pack%20cementation" title=" pack cementation"> pack cementation</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidation%20resistance" title=" oxidation resistance"> oxidation resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminized%20steel" title=" aluminized steel "> aluminized steel </a> </p> <a href="https://publications.waset.org/abstracts/15965/high-temperature-oxidation-behavior-of-aluminized-steel-by-arc-spray-and-cementation-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15965.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">468</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> Pregnancy through the Lens of Iranian Women with HIV: A Qualitative</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20BehboodiI-Moghadam">Zahra BehboodiI-Moghadam</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohre%20Khalajinia"> Zohre Khalajinia</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Reza%20Nikbakht%20Nasrabadi"> Ali Reza Nikbakht Nasrabadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Minoo%20Mohraz"> Minoo Mohraz </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of our study was to explore and describe the experiences of pregnant women with HIV in Iran. A qualitative exploratory study with conventional content analysis was used. Twelve pregnant women with HIV who referred to perinatal care at the Imam Khomeini Hospital Behavioral Diseases Consultation: Center in Tehran were recruited to participate in in-depth interviews. The average age of the participants was 32.5 years. Four main themes were extracted from the data: “fear and hope, “stigma and discrimination, “marital life stability” and “trust”. The findings reveal the pregnant women living with HIV are vulnerable and need professional support.

Therefore ERα gene could be a possible candidate for preeclampsia(PE) susceptibility. In the current study, we aimed to investigate the association of the ERα gene polymorphisms and PE in an Iranian population. Methods: One hundred ninety-two pregnant women with PE and 186 normotensive women were genotyped for ERα gene (PvuII and XbaI) polymorphisms by PCR-RFLP method. Results: The frequency of alleles and genotypes of ERα PvuII and XbaI polymorphisms were not different between PE and normotensive control women. However, higher frequency of GG genotype was observed in women with severe PE compared to mild PE (OR, 1.8 [95% CI, 1.1 to 3]; P = 0.02) and in severe PE compared to normotensive women [OR= 1.8(1.1-3), P=0.02] after adjusting for age, ethnicity and primiparity. Conclusions: The GG genotype of ERα XbaI polymorphism could be a genetic risk factor for PE predisposition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=estrogen%20receptor-%CE%B1" title="estrogen receptor-α">estrogen receptor-α</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=gene" title=" gene"> gene</a>, <a href="https://publications.waset.org/abstracts/search?q=preeclampsia" title=" preeclampsia"> preeclampsia</a> </p> <a href="https://publications.waset.org/abstracts/65226/the-association-of-estrogen-receptor-alpha-xbai-gg-genotype-and-severe-preeclampsia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65226.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">308</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> Alumina Nanoparticles in One-Pot Synthesis of Pyrazolopyranopyrimidinones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Khodabakhshi">Saeed Khodabakhshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alimorad%20Rashidi"> Alimorad Rashidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziba%20Tavakoli"> Ziba Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajad%20Kiani"> Sajad Kiani</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadegh%20Dastkhoon"> Sadegh Dastkhoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alumina nanoparticles (γ-Al2O3 NPs) were prepared via a new and simple synthetic route and characterized by field emission scanning electron microscope, X-ray diffraction, and Fourier transform infrared spectroscopy.

To this end, understanding the relationship between knowledge management processes and different aspects of strategic thinking (followed by long-term organizational planning) should be considered. This research examines the relationship between each of the five knowledge management processes (creation, storage, transfer, audit, and deployment) with each dimension of strategic thinking (vision, creativity, thinking, communication and analysis) in one of the major sectors of the food industry in Iran. In this research, knowledge management and its dimensions (knowledge acquisition, knowledge storage, knowledge transfer, knowledge auditing, and finally knowledge utilization) as independent variables and strategic thinking and its dimensions (creativity, systematic thinking, vision, strategic analysis, and strategic communication) are considered as the dependent variable. The statistical population of this study consisted of 245 managers and employees of Minoo Food Industrial Group in Tehran. In this study, a simple random sampling method was used, and data were collected by a questionnaire designed by the research team. Data were analyzed using SPSS 21 software. LISERL software is also used for calculating and drawing models and graphs. Among the factors investigated in the present study, knowledge storage with 0.78 had the most effect, and knowledge transfer with 0.62 had the least effect on knowledge management and thus on strategic thinking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title="knowledge management">knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20thinking" title=" strategic thinking"> strategic thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management%20processes" title=" knowledge management processes"> knowledge management processes</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20industry" title=" food industry"> food industry</a> </p> <a href="https://publications.waset.org/abstracts/111054/the-relationship-between-knowledge-management-processes-and-strategic-thinking-at-the-organization-level" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111054.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">170</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">27</span> Numerical Analysis of Water Hammer in a Viscoelastic Pipe System Considering Fluid Structure Interaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Tavakoli%20Shirazi">N.

Tests have been conducted in a reservoir-pipe-valve system configured of a main viscoelastic pipeline and two short steel pipes placed upstream and downstream of the main pipe. Rapid closure of a manually operated valve at the downstream end generates water hammer. Experimental measurements at several positions along the pipeline have been collected from the papers. Computer simulations of the experiment have been performed and the results of runs with various options affecting the water hammer are provided and discussed. It is shown that the incorporation of viscoelastic pipe wall mechanical behavior in the hydraulic transient model contributes to a favorable fitting between numerical results and observed data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pipe%20system" title="pipe system">pipe system</a>, <a href="https://publications.waset.org/abstracts/search?q=PVC%20pipe" title=" PVC pipe"> PVC pipe</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelasticity" title=" viscoelasticity"> viscoelasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20hammer" title=" water hammer"> water hammer</a> </p> <a href="https://publications.waset.org/abstracts/29507/numerical-analysis-of-water-hammer-in-a-viscoelastic-pipe-system-considering-fluid-structure-interaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">466</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> How Geant4 Hadronic Models Handle Tracking of Pion Particles Resulting from Antiproton Annihilation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20B.%20Tavakoli">M.

Because of lack of reliable absolute dose measurements attempts to find out the radiobiological characteristics of antiproton have not reached to a reasonable result yet. From the other side, application of Geant4 in medical approaches is increased followed by Geant4-DNA project which focuses on using this code to predict radiation effects in the cellular scale. This way we can exploit Geant4-DNA results for antiproton. Unfortunately, previous studies showed there are serious problem in simulating an antiproton beam using Geant4. Since most of the problem was in the Bragg peak region which antiproton annihilates there, in this work we tried to understand if the problem came from the way in which Geant4 handles annihilation products especially pion particles. This way, we can predict the source of the dose discrepancies between Geant4 simulations and dose measurements done in CERN. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Geant4" title="Geant4">Geant4</a>, <a href="https://publications.waset.org/abstracts/search?q=antiproton" title=" antiproton"> antiproton</a>, <a href="https://publications.waset.org/abstracts/search?q=annihilation" title=" annihilation"> annihilation</a>, <a href="https://publications.waset.org/abstracts/search?q=pion%20plus" title=" pion plus"> pion plus</a>, <a href="https://publications.waset.org/abstracts/search?q=pion%20minus" title=" pion minus"> pion minus</a> </p> <a href="https://publications.waset.org/abstracts/17905/how-geant4-hadronic-models-handle-tracking-of-pion-particles-resulting-from-antiproton-annihilation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17905.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">657</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> The Law of Treaties and National Security of Islamic Republic of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20M.%20Tavakoli%20Sani">S.

These obligations had been defined according to the type of legislation of Iran in many aspects. Therefore, there are several treaties at international level which requires Iran’s security to come in contact with obligations in these treaties in a way that an obstacle to join to them and their passage in parliament. This issue is a typical category which every country pays attention to be accepted in treaties or to include their national security in that treaties and also they can see the related treaties from this perspective, but this issue that 'what is the concept of Iran’s national security', and 'To what extent it is changed in recent years, especially after Islamic Revolution' are important issues that can be criticized. Thus, this study is trying to assess singed treaties from the perspective of Iran’s national security according of the true meaning of treaty and to investigate how the international treaties may be in conflict with Iran’s national security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=treaties" title="treaties">treaties</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20security" title=" national security"> national security</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20Revolution" title=" Islamic Revolution"> Islamic Revolution</a> </p> <a href="https://publications.waset.org/abstracts/1968/the-law-of-treaties-and-national-security-of-islamic-republic-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1968.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">470</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">24</span> A Framework for Review Spam Detection Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadali%20Tavakoli">Mohammadali Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Heydari"> Atefeh Heydari</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuriati%20Ismail"> Zuriati Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Naomie%20Salim"> Naomie Salim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the increasing number of people reviewing products online in recent years, opinion sharing websites has become the most important source of customers’ opinions. Unfortunately, spammers generate and post fake reviews in order to promote or demote brands and mislead potential customers.

However, research in this area is not adequate, and many critical problems related to spam detection have not been solved to date. To provide green researchers in the domain with a great aid, in this paper, we have attempted to create a high-quality framework to make a clear vision on review spam-detection methods.

In our project, it was developed a patient tracking platform (PTP) where first responders triage the patients with an electronic tag which report the location and some information of each patient during his/her movement. This platform includes: 1) near field communication (NFC) tags (ISO 14443), 2) smart mobile phones (Android-base version 4.2.2), 3) Base station laptops (Windows), 4) server software, 5) Android software to use by first responders, 5) disaster command software, and 6) system architecture. Our model has been completed through literature review, Delphi technique, focus group, design the platform, and implement in an earthquake exercise. This paper presents consideration for content, function, and technologies that must apply for patient tracking in medical emergencies situations. It is demonstrated the robustness of the patient tracking platform (PTP) in tracking 6 patients in a simulated earthquake situation in the yard of the relief and rescue department of Isfahan’s Red Crescent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=test%20and%20evaluation" title="test and evaluation">test and evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20tracking%20platform" title=" patient tracking platform"> patient tracking platform</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/112288/test-and-evaluation-of-patient-tracking-platform-in-an-earthquake-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112288.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">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> The Study of the Concept of Aesthetics in Architecture Derived from the Ideas of Jörg Kurt Greuther</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mana%20Pirhadi">Mana Pirhadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Pirhadi"> Maryam Pirhadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Tavakoli"> Fatemeh Tavakoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As there are several styles and attitudes among the practitioners of the present time, it is difficult to achieve a definition of beauty for contemporary architecture and aesthetic concepts has different frameworks in various disciplines. Beauty can be regarded as one of the most important elements of architecture; therefore, having a clear understanding of beauty can help architects and audiences to create or analyze an architectural work. This paper investigates the assumption that we can have a clearer understanding of the concept of aesthetics in architecture by analyzing the ideas of the contemporary analyst of architectural aesthetics, Jörg Greuther. Thus, the question is how the concept of aesthetics in architecture will be analyzed in their thoughts. In general, the paper aims to examine aesthetic concepts in the contemporary era that are expressed relying on Greuther's views. The paper adopts a descriptive-analytic approach in terms of methodology. Finally, through the study of the viewpoints of various scholars and specifically considering Greuther's definition that focuses on the effect of psychological-social factors on human perception and formation of the schema, it could be said that aesthetics means to have a good knowledge of truth and understand it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aesthetics" title="aesthetics">aesthetics</a>, <a href="https://publications.waset.org/abstracts/search?q=beauty%20perception" title=" beauty perception"> beauty perception</a>, <a href="https://publications.waset.org/abstracts/search?q=contemporary%20architecture" title=" contemporary architecture"> contemporary architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%B6rg%20Greuther" title=" Jörg Greuther"> Jörg Greuther</a> </p> <a href="https://publications.waset.org/abstracts/66961/the-study-of-the-concept-of-aesthetics-in-architecture-derived-from-the-ideas-of-jorg-kurt-greuther" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66961.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">332</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> Study of a Lean Premixed Combustor: A Thermo Acoustic Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minoo%20Ghasemzadeh">Minoo Ghasemzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Rouzbeh%20Riazi"> Rouzbeh Riazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shidvash%20Vakilipour"> Shidvash Vakilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Ramezani"> Alireza Ramezani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, thermo acoustic oscillations of a lean premixed combustor has been investigated, and a mono-dimensional code was developed in this regard. The linearized equations of motion are solved for perturbations with time dependence〖 e〗^iwt. Two flame models were considered in this paper and the effect of mean flow and boundary conditions were also investigated. After manipulation of flame heat release equation together with the equations of flow perturbation within the main components of the combustor model (i.e., plenum/ premixed duct/ and combustion chamber) and by considering proper boundary conditions between the components of model, a system of eight homogeneous equations can be obtained. This simplification, for the main components of the combustor model, is convenient since low frequency acoustic waves are not affected by bends. Moreover, some elements in the combustor are smaller than the wavelength of propagated acoustic perturbations. A convection time is also assumed to characterize the required time for the acoustic velocity fluctuations to travel from the point of injection to the location of flame front in the combustion chamber. The influence of an extended flame model on the acoustic frequencies of combustor was also investigated, assuming the effect of flame speed as a function of equivalence ratio perturbation, on the rate of flame heat release. The abovementioned system of equations has a related eigenvalue equation which has complex roots. The sign of imaginary part of these roots determines whether the disturbances grow or decay and the real part of these roots would give the frequency of the modes. The results show a reasonable agreement between the predicted values of dominant frequencies in the present model and those calculated in previous related studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combustion%20instability" title="combustion instability">combustion instability</a>, <a href="https://publications.waset.org/abstracts/search?q=dominant%20frequencies" title=" dominant frequencies"> dominant frequencies</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20speed" title=" flame speed"> flame speed</a>, <a href="https://publications.waset.org/abstracts/search?q=premixed%20combustor" title=" premixed combustor"> premixed combustor</a> </p> <a href="https://publications.waset.org/abstracts/24231/study-of-a-lean-premixed-combustor-a-thermo-acoustic-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24231.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">379</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> Leveraging Quality Metrics in Voting Model Based Thread Retrieval</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Heydari">Atefeh Heydari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadali%20Tavakoli"> Mohammadali Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Zuriati%20Ismail"> Zuriati Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Naomie%20Salim"> Naomie Salim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seeking and sharing knowledge on online forums have made them popular in recent years. Although online forums are valuable sources of information, due to variety of sources of messages, retrieving reliable threads with high quality content is an issue. Majority of the existing information retrieval systems ignore the quality of retrieved documents, particularly, in the field of thread retrieval. In this research, we present an approach that employs various quality features in order to investigate the quality of retrieved threads. Different aspects of content quality, including completeness, comprehensiveness, and politeness, are assessed using these features, which lead to finding not only textual, but also conceptual relevant threads for a user query within a forum. To analyse the influence of the features, we used an adopted version of voting model thread search as a retrieval system. We equipped it with each feature solely and also various combinations of features in turn during multiple runs. The results show that incorporating the quality features enhances the effectiveness of the utilised retrieval system significantly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=content%20quality" title="content quality">content quality</a>, <a href="https://publications.waset.org/abstracts/search?q=forum%20search" title=" forum search"> forum search</a>, <a href="https://publications.waset.org/abstracts/search?q=thread%20retrieval" title=" thread retrieval"> thread retrieval</a>, <a href="https://publications.waset.org/abstracts/search?q=voting%20techniques" title=" voting techniques"> voting techniques</a> </p> <a href="https://publications.waset.org/abstracts/42749/leveraging-quality-metrics-in-voting-model-based-thread-retrieval" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42749.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">213</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> The Role of the Injured Party's Fault in the Apportionment of Damages in Tort Law: A Comparative-Historical Study between Common Law and Islamic Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Tavakoli%20Nia">Alireza Tavakoli Nia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to understand the role of the injured party's fault in dividing liability, we studied its historical background. In common law, the traditional contributory negligence rule was a complete defense. Then the legislature and judicial procedure modified that rule to one of apportionment. In Islamic law, too, the Action rule was at first used when the injured party was the sole cause, but jurists expanded the scope of this rule, so this rule was used in cases where both the injured party's fault and that of the other party are involved. There are some popular approaches for apportionment of damages. Some common law countries like Britain had chosen ‘the causal potency approach’ and ‘fixed apportionment’. Islamic countries like Iran have chosen both ‘the relative blameworthiness’ and ‘equal apportionment’ approaches. The article concludes that both common law and Islamic law believe in the division of responsibility between a wrongdoer claimant and the defendant. In contrast, in the apportionment of responsibility, Islamic law mostly believes in equal apportionment that is way easier and saves time and money, but common law legal systems have chosen the causal potency approach, which is more complicated than the rival approach but is fairer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contributory%20negligence" title="contributory negligence">contributory negligence</a>, <a href="https://publications.waset.org/abstracts/search?q=tort%20law" title=" tort law"> tort law</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20apportionment" title=" damage apportionment"> damage apportionment</a>, <a href="https://publications.waset.org/abstracts/search?q=common%20law" title=" common law"> common law</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20law" title=" Islamic law "> Islamic law </a> </p> <a href="https://publications.waset.org/abstracts/138280/the-role-of-the-injured-partys-fault-in-the-apportionment-of-damages-in-tort-law-a-comparative-historical-study-between-common-law-and-islamic-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138280.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">147</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> Investigation of Information Security Incident Management Based on International Standard ISO/IEC 27002 in Educational Hospitals in 2014</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nahid%20Tavakoli">Nahid Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Asghar%20Ehteshami"> Asghar Ehteshami</a>, <a href="https://publications.waset.org/abstracts/search?q=Akbar%20Hassanzadeh"> Akbar Hassanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Amini"> Fatemeh Amini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The Information security incident management guidelines was been developed to help hospitals to meet their information security event and incident management requirements.

Methods: This was a cross-sectional study to investigate on Information Security Incident Management of educational hospitals in 2014. Based on ISO/IEC 27002 standards, two checklists were applied to check the compliance with standards on Reporting Information Security Events and Weakness and Management of Information Security Incidents and Improvements. One inspector was trained to carry out the assessments in the hospitals. The data was analyzed by SPSS. Findings: In general the score of compliance Information Security Incident Management requirements in two steps; Reporting Information Security Events and Weakness and Management of Information Security Incidents and Improvements was %60. There was the significant difference in various compliance levels among the hospitals (p-value<o/oo1). Conclusions: According to ISO/IEC 27002 standards, none of the hospitals were completely complained with to present the best possible Information Security Incident Management. One of the most important aspects to consider when developing the information security incident management policy is to define the roles and responsibilities of the information security incident response team. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20security%20incident%20management" title="information security incident management">information security incident management</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20security%20management" title=" information security management"> information security management</a>, <a href="https://publications.waset.org/abstracts/search?q=standards" title=" standards"> standards</a>, <a href="https://publications.waset.org/abstracts/search?q=hospitals" title=" hospitals "> hospitals </a> </p> <a href="https://publications.waset.org/abstracts/38364/investigation-of-information-security-incident-management-based-on-international-standard-isoiec-27002-in-educational-hospitals-in-2014" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38364.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">575</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> A Case Study of Control of Blast-Induced Ground Vibration on Adjacent Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Mahdavinezhad">H.

Researchers have developed a number of experimental equations to estimate the peak particle velocity (PPV), in which the experimental constants must be obtained at the site of the explosion by fitting the data from experimental explosions. In this study, the most important of these equations was evaluated for strong massive conglomerates around Dez Dam by collecting data on explosions, including 30 particle velocities, 27 displacements, 27 vibration frequencies and 27 acceleration of earth vibration at different distances; they were recorded in the form of two types of detonation systems, NUNEL and electric. Analysis showed that the data from the explosion had the best correlation with the cube root of the explosive, R2=0.8636, but overall the correlation coefficients are not much different. To estimate the vibration in this project, data regression was performed in the other formats, which resulted in the presentation of new equation with R2=0.904 correlation coefficient. Finally according to the importance of the studied structures in order to ensure maximum non damage to adjacent structures for each diagram, a range of application was defined so that for distances 0 to 70 meters from blast site, exponent n=0.33 and for distances more than 70 m, n =0.66 was suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blasting" title="blasting">blasting</a>, <a href="https://publications.waset.org/abstracts/search?q=blast-induced%20vibration" title=" blast-induced vibration"> blast-induced vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20equations" title=" empirical equations"> empirical equations</a>, <a href="https://publications.waset.org/abstracts/search?q=PPV" title=" PPV"> PPV</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel" title=" tunnel"> tunnel</a> </p> <a href="https://publications.waset.org/abstracts/135874/a-case-study-of-control-of-blast-induced-ground-vibration-on-adjacent-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135874.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">131</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> Role of mHealth in Effective Response to Disaster</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20H.%20Yarmohamadian">Mohammad H.

Disaster response continues to face the challenges in health care sector in all countries. Information and communication management is a significant challenge in disaster scene. During the last decades, rapid advances in information technology have led to manage information effectively and improve communication in health care setting. Information technology is a vital solution for effective response to disasters and emergencies so that if an efficient ICT-based health information system is available, it will be highly valuable in such situation. Of that, mobile technology represents a nearly computing technology infrastructure that is accessible, convenient, inexpensive and easy to use. Most projects have not yet reached the deployment stage, but evaluation exercises show that mHealth should allow faster processing and transport of patients, improved accuracy of triage and better monitoring of unattended patients at a disaster scene. Since there is a high prevalence of cell phones among world population, it is expected the health care providers and managers to take measures for applying this technology for improvement patient safety and public health in disasters. At present there are challenges in the utilization of mhealth in disasters such as lack of structural and financial issues in our country. In this paper we will discuss about benefits and challenges of mhealth technology in disaster setting considering connectivity, usability, intelligibility, communication and teaching for implementing this technology for disaster response. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20technology" title="information technology">information technology</a>, <a href="https://publications.waset.org/abstracts/search?q=mhealth" title=" mhealth"> mhealth</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster" title=" disaster"> disaster</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20response" title=" effective response "> effective response </a> </p> <a href="https://publications.waset.org/abstracts/17274/role-of-mhealth-in-effective-response-to-disaster" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17274.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">440</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> The Impact of Fiscal Policy on Gross Domestic Product under Contributions of Level of External Debt in Developing Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zohreh%20Bang%20Tavakoli">Zohreh Bang Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuktika%20Chatterjee"> Shuktika Chatterjee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates the fiscal policy impact on countries’ economic growth in developing countries with a different external debt level. The fiscal policy effectiveness has been re-emphasized in the global financial crisis of 2008 with the external debt as its new contemporary driver (Ruščáková and Semančíková, 2016). According to Bouakez, (2014 ) different theories have proposed the economic consequence of fiscal policy, specifically for developing countries. However, fiscal policy literature is lacking research regarding the fiscal policy’s effectiveness with the external debt’s contributions through comprehensive study (Canh, 2018). Also, according to scholars, high levels of external debt will influence economic growth. First, through foreign resources and channel of investment in which high level of debt decreases the amount of foreign investment in the developing countries. Second, through the deterioration of foreign investors and fiscal policies related to a high level of debt (Cordella, et.al., 2010). Therefore, this study proposed that only countries with a low external debt level and appropriate fiscal policies and good quality institutions can gain the proper quantity and quality of foreign investors, which will help the economic growth. For this, this research is examining the impact of fiscal policy on developing countries' economic growth in the situation of different external debt levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fiscal%20policy" title="fiscal policy">fiscal policy</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20debt" title=" external debt"> external debt</a>, <a href="https://publications.waset.org/abstracts/search?q=gross%20domestic%20product" title=" gross domestic product"> gross domestic product</a>, <a href="https://publications.waset.org/abstracts/search?q=developing%20countries" title=" developing countries"> developing countries</a> </p> <a href="https://publications.waset.org/abstracts/139300/the-impact-of-fiscal-policy-on-gross-domestic-product-under-contributions-of-level-of-external-debt-in-developing-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139300.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">160</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> A Supervised Approach for Detection of Singleton Spam Reviews</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Heydari">Atefeh Heydari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadali%20Tavakoli"> Mohammadali Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Naomie%20Salim"> Naomie Salim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, we have witnessed that online reviews are the most important source of customers’ opinion. They are progressively more used by individuals and organisations to make purchase and business decisions. Unfortunately, for the reason of profit or fame, frauds produce deceptive reviews to hoodwink potential customers. Their activities mislead not only potential customers to make appropriate purchasing decisions and organisations to reshape their business, but also opinion mining techniques by preventing them from reaching accurate results. Spam reviews could be divided into two main groups, i.e. multiple and singleton spam reviews. Detecting a singleton spam review that is the only review written by a user ID is extremely challenging due to lack of clue for detection purposes. Singleton spam reviews are very harmful and various features and proofs used in multiple spam reviews detection are not applicable in this case. Current research aims to propose a novel supervised technique to detect singleton spam reviews. To achieve this, various features are proposed in this study and are to be combined with the most appropriate features extracted from literature and employed in a classifier. In order to compare the performance of different classifiers, SVM and naive Bayes classification algorithms were used for model building. The results revealed that SVM was more accurate than naive Bayes and our proposed technique is capable to detect singleton spam reviews effectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=classification%20algorithms" title="classification algorithms">classification algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=Na%C3%AFve%20Bayes" title=" Naïve Bayes"> Naïve Bayes</a>, <a href="https://publications.waset.org/abstracts/search?q=opinion%20review%20spam%20detection" title=" opinion review spam detection"> opinion review spam detection</a>, <a href="https://publications.waset.org/abstracts/search?q=singleton%20review%20spam%20detection" title=" singleton review spam detection"> singleton review spam detection</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a> </p> <a href="https://publications.waset.org/abstracts/36387/a-supervised-approach-for-detection-of-singleton-spam-reviews" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36387.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">309</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> Effect of Fat Percentage and Prebiotic Composition on Proteolysis, ACE-Inhibitory and Antioxidant Activity of Probiotic Yogurt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20B.%20HabibiNajafi">Mohammad B.

In this study, the effects of adding prebiotic ingredients (inulin and wheat fiber) and fat percentage (0%, 2% and 3.5%) in yogurt containing probiotic <em>Lactobacillus casei</em> on physicochemical properties, degree of proteolysis, antioxidant and ACE-inhibitory activity within 21 days of storage at 5 ± 1 °C were evaluated. The results of statistical analysis showed that the application of prebiotic compounds led to a significant increase in water holding capacity, proteolysis and ACE-inhibitory of samples. The degree of proteolysis in yogurt increases as storage time elapses (P < 0.05) but when proteolysis exceeds a certain threshold, this trend begins to decline. Also, during storage time, water holding capacity reduced initially but increased thereafter. Moreover, based on our findings, the survival of <em>Lactobacillus casei</em> in samples treated with inulin and wheat fiber increased significantly in comparison to the control sample (P < 0.05) whereas the effect of fat percentage on the survival of probiotic bacteria was not significant (P = 0.095). Furthermore, the effect of prebiotic ingredients and the presence of probiotic cultures on the antioxidant activity of samples was significant (P < 0.05). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probiotic%20yogurt" title="probiotic yogurt">probiotic yogurt</a>, <a href="https://publications.waset.org/abstracts/search?q=proteolysis" title=" proteolysis"> proteolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ACE-inhibitory" title=" ACE-inhibitory"> ACE-inhibitory</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a> </p> <a href="https://publications.waset.org/abstracts/72186/effect-of-fat-percentage-and-prebiotic-composition-on-proteolysis-ace-inhibitory-and-antioxidant-activity-of-probiotic-yogurt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72186.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">253</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> Optimality Conditions for Weak Efficient Solutions Generated by a Set Q in Vector Spaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elham%20Kiyani">Elham Kiyani</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Mansour%20Vaezpour"> S.

The algebraic concepts of interior and closure are useful to study optimization problems without topology. So, we define Q-weak efficient solutions generated by the algebraic interior of a set Q, where Q is not necessarily convex. Studying nonconvex vector optimization is valuable since, for a convex cone K in topological spaces, we have int(K)=cor(K), which means that topological interior of a convex cone K is equal to the algebraic interior of K. Moreover, we used the scalarization technique including the distance function generated by the vectorial closure of a set to characterize these Q-weak efficient solutions. Scalarization is a useful approach for solving vector optimization problems. This technique reduces the optimization problem to a scalar problem which tends to be an optimization problem with a real-valued objective function. For instance, Q-weak efficient solutions of vector optimization problems can be characterized and computed as solutions of appropriate scalar optimization problems. In the convex case, linear functionals can be used as objective functionals of the scalar problems. But in the nonconvex case, we should present a suitable objective function. It is the aim of this paper to present a new distance function that be useful to obtain sufficient and necessary conditions for Q-weak efficient solutions of general optimization problems via scalarization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=weak%20efficient" title="weak efficient">weak efficient</a>, <a href="https://publications.waset.org/abstracts/search?q=algebraic%20interior" title=" algebraic interior"> algebraic interior</a>, <a href="https://publications.waset.org/abstracts/search?q=vector%20closure" title=" vector closure"> vector closure</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20space" title=" linear space"> linear space</a> </p> <a href="https://publications.waset.org/abstracts/94737/optimality-conditions-for-weak-efficient-solutions-generated-by-a-set-q-in-vector-spaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94737.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">228</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">11</span> Rapid Mitochondrial Reactive Oxygen Species Production Precedes NF-κB Activation and Pro-inflammatory Responses in Macrophages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parinaz%20Tavakoli%20Zaniani">Parinaz Tavakoli Zaniani</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Balomenos"> Dimitrios Balomenos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mitochondrial reactive oxygen species (mROS) play a crucial role in macrophage pro-inflammatory activation, although a detailed understanding of the mechanism and kinetics by which mROS drive signaling molecules is still lacking. In general, it is thought that NF-κB activation drives mROS and general ROS production. Here, We performed a detailed kinetic analysis of mROS production during macrophage activation. We found early mROS generation after LPS (lipopolysaccharide) stimulation. Remarkably as early as 5 minutes, mROS signaling promoted initial NF-κB, MAPK activation and pro-inflammatory cytokine production, as established through inhibition or quenching of mROS. On the contrary, NF-κB inhibition had no effect on mROS production. Our findings point to a mechanism by which mROS increase TRAF-6 ubiquitination and, thus NF-κB activity. mROS inhibition reduced LPS-induced lethality in an in vivo septic shock model by controlling pro-inflammatory cytokine production. Overall, our research provides novel insights into the role of mROS as a primary messenger in the pathway of macrophage and as a regulator of inflammatory responses. We found that early mROS production promotes initial NF-κB, and MAPK activation by regulating TRAF-6 ubiquitination and that mROS inhibition can reduce LPS-induced inflammatory cytokines and lethality in a septic shock model. These findings might lead to novel immunotherapeutic strategies targeting early mROS production and control of extreme inflammation in the context of sepsis and other inflammatory diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mitochondria" title="mitochondria">mitochondria</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species" title=" reactive oxygen species"> reactive oxygen species</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20factor%20%CE%BAB" title=" nuclear factor κB"> nuclear factor κB</a>, <a href="https://publications.waset.org/abstracts/search?q=lipopolysaccharide" title=" lipopolysaccharide"> lipopolysaccharide</a>, <a href="https://publications.waset.org/abstracts/search?q=macrophages" title=" macrophages"> macrophages</a> </p> <a href="https://publications.waset.org/abstracts/166436/rapid-mitochondrial-reactive-oxygen-species-production-precedes-nf-kb-activation-and-pro-inflammatory-responses-in-macrophages" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166436.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">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Effects of Advanced Periodontal Disease on Hematological Parameters in Adult Dogs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahzad%20Yousefi">Mahzad Yousefi</a>, <a href="https://publications.waset.org/abstracts/search?q=Azin%20Tavakoli"> Azin Tavakoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Periodontal disease is an inflammatory reaction; therefore, it is predicted that changes may occur in some inflammatory parameters that can be detected in routine blood tests. The objective of this study was to evaluate the hematological and biochemistry changes that occur in dogs affected with advanced stages of periodontal disease. 87 dogs were diagnosed with periodontal disease (PD group), and 76 healthy dogs entered the study. The PD dogs had been affected with periodontitis stage 3 or 4 and were candidates for any dental extractions. The healthy dogs were either referred for annual checkups or for issuing health travel certificates that their owners asked for complete lab tests. Neither the diseased nor healthy subjects had a history of infectious, or other general health problems or surgery in the past 3 months. Age, as well as all hematologic including PCV, WBC and RBC count, Hb, MCV, MCH, MCHC, PLT, CBC, NLR, and biochemistry data, including total protein, albumin, glucose, BUN, Creatinine, ALT, AST, and ALP, were recorded and analyzed statistically. Results confirmed that aging has a significant direct relationship with the advanced stages of periodontal disease. Mild leukocytosis occurred in the diseased group; however, it was not significant. Also, the mean total protein of the PD group was lower than that of the healthy dogs, and serum levels of albumin were found to be lower significantly in the diseased group (P<0.05). Mean ±SD amount of Platelet, MCH, and ALT were significantly higher in the diseased group in comparison to the healthy dogs (P<0.05). No significant differences were reported in other evaluated parameters. It is concluded that CBC indices of PD dogs are not systemic inflammatory; however, only a decrease in albumin showed inflammatory responses. Some indices in routine laboratory tests can be changed significantly during advanced stages of the periodontal disease dogs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=periodontal%20disease" title="periodontal disease">periodontal disease</a>, <a href="https://publications.waset.org/abstracts/search?q=dogs" title=" dogs"> dogs</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20factors" title=" hematological factors"> hematological factors</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20stages" title=" advanced stages"> advanced stages</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20tests" title=" blood tests"> blood tests</a> </p> <a href="https://publications.waset.org/abstracts/183047/effects-of-advanced-periodontal-disease-on-hematological-parameters-in-adult-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183047.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">9</span> Patient Tracking Challenges During Disasters and Emergencies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20H.%20Yarmohammadian">Mohammad H.

The concept of tracking has different denotations. One of the meanings refers to tracking patients’ physical locations and the other meaning refers to tracking patients ‘medical needs during emergency services. The main goal of patient tracking is to provide patient safety during disaster and emergencies and manage the flow of patient and information in different locations. In most of cases, there are not sufficient and accurate data regarding the number of injuries, medical conditions and their accommodation and transference. The objective of the present study is to survey on patient tracking issue in natural disaster and emergencies. Methods: This was a narrative study in which the population was E-Journals and the electronic database such as PubMed, Proquest, Science direct, Elsevier, etc. Data was gathered by Extraction Form. All data were analyzed via content analysis. Results: In many countries there is no appropriate and rapid method for tracking patients and transferring victims after the occurrence of incidents. The absence of reliable data of patients’ transference and accommodation, even in the initial hours and days after the occurrence of disasters, and coordination for appropriate resource allocation, have faced challenges for evaluating needs and services challenges. Currently, most of emergency services are based on paper systems, while these systems do not act appropriately in great disasters and incidents and this issue causes information loss. Conclusion: Patient tracking system should update the location of patients or evacuees and information related to their states. Patients’ information should be accessible for authorized users to continue their treatment, accommodation and transference. Also it should include timely information of patients’ location as soon as they arrive somewhere and leave therein such a way that health care professionals can be able to provide patients’ proper medical treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=patient%20tracking" title="patient tracking">patient tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=challenges" title=" challenges"> challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster" title=" disaster"> disaster</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency" title=" emergency "> emergency </a> </p> <a href="https://publications.waset.org/abstracts/38363/patient-tracking-challenges-during-disasters-and-emergencies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38363.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">8</span> Synthesis of PVA/γ-Fe2O3 Used in Cancer Treatment by Hyperthermia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajjad%20Seifi%20Mofarah">Sajjad Seifi Mofarah</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Sadrnezhaad"> S.

Hyperthermia is a traditional therapy that, along with a creation of a medically approved level of heat with the help of an alternating magnetic AC current, results in the destruction of cancer cells by heat. This paper gives details regarding the production of the spherical nanocomposite PVA/γ-Fe2O3 in order to be used for medical purposes such as tumor treatment by hyperthermia. To reach a suitable and evenly distributed temperature, the nanocomposite with core-shell morphology and spherical form within a 100 to 200 nanometer size was created using phase separation emulsion, in which the magnetic nano-particles γ-Fe2O3 with an average particle size of 20 nano-meters and with different percentages of 0.2, 0.4, 0.5, and 0.6 were covered by polyvinyl alcohol. The main concern in hyperthermia and heat treatment is achieving desirable specific absorption rate (SAR) and one of the most critical factors in SAR is particle size. In this project all attempts has been done to reach minimal size and consequently maximum SAR. The morphological analysis of the spherical structure of the nanocomposite PVA/γ-Fe2O3 was achieved by SEM analyses and the study of the chemical bonds created was made possible by FTIR analysis. To investigate the manner of magnetic nanocomposite particle size distribution a DLS experiment was conducted. Moreover, to determine the magnetic behavior of the γ-Fe2O3 particle and the nanocomposite PVA/γ-Fe2O3 in different concentrations a VSM test was conducted. To sum up, creating magnetic nanocomposites with a spherical morphology that would be employed for drug loading opens doors to new approaches in developing nanocomposites that provide efficient heat and a controlled release of drug simultaneously inside the magnetic field, which are among their positive characteristics that could significantly improve the recovery process in patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title="nanocomposite">nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperthermia" title=" hyperthermia"> hyperthermia</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20therapy" title=" cancer therapy"> cancer therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20releasing" title=" drug releasing"> drug releasing</a> </p> <a href="https://publications.waset.org/abstracts/5423/synthesis-of-pvagh-fe2o3-used-in-cancer-treatment-by-hyperthermia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5423.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">7</span> The Association between IFNAR2 and Dpp9 Genes Single Nucleotide Polymorphisms Frequency with COVID-19 Severity in Iranian Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sima%20Parvizi%20Omran">Sima Parvizi Omran</a>, <a href="https://publications.waset.org/abstracts/search?q=Rezvan%20Tavakoli"> Rezvan Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahnaz%20Safari"> Mahnaz Safari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Aghasadeghi"> Mohammadreza Aghasadeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolfazl%20Fateh"> Abolfazl Fateh</a>, <a href="https://publications.waset.org/abstracts/search?q=Pooneh%20Rahimi"> Pooneh Rahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: SARS-CoV-2, a single-stranded RNA betacoronavirus causes the global outbreak of coronavirus disease 2019 (COVID-19). Several clinical and scientific concerns are raised by this pandemic. Genetic factors can contribute to pathogenesis and disease susceptibility. There are single nucleotide polymorphisms (SNPs) in many of the genes in the immune system that affect the expression of specific genes or functions of some proteins related to immune responses against viral infections. In this study, we analyzed the impact of polymorphism in the interferon alpha and beta receptor subunit 2 (IFNAR2) and dipeptidyl peptidase 9 (Dpp9) genes and clinical parameters on the susceptibility and resistance to Coronavirus disease (COVID-19). Methods: A total of 330- SARS-CoV-2 positive patients (188 survivors and 142 nonsurvivors) were included in this study. All single-nucleotide polymorphisms (SNPs) on IFNAR2 (rs2236757) and Dpp9 (rs2109069) were genotyped by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: In survivor patients, the frequency of the favourable genotypes of IFNAR2 SNP (rs2236757 GC) was significantly higher than in nonsurvivor patients, and also Dpp9 (rs2109069 AT) genotypes were associated with the severity of COVID-19 infection. Conclusions: This study demonstrated that the severity of COVID- 19 patients was strongly associated with clinical parameters and unfavourable IFNAR2, Dpp9 SNP genotypes. In order to establish the relationship between host genetic factors and the severity of COVID-19 infection, further studies are needed in multiple parts of the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SARS-CoV-2" title="SARS-CoV-2">SARS-CoV-2</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=interferon%20alpha%20and%20beta%20receptor%20subunit%202" title=" interferon alpha and beta receptor subunit 2"> interferon alpha and beta receptor subunit 2</a>, <a href="https://publications.waset.org/abstracts/search?q=dipeptidyl%20peptidase%209" title=" dipeptidyl peptidase 9"> dipeptidyl peptidase 9</a>, <a href="https://publications.waset.org/abstracts/search?q=single-nucleotide%20polymorphisms" title=" single-nucleotide polymorphisms"> single-nucleotide polymorphisms</a> </p> <a href="https://publications.waset.org/abstracts/155792/the-association-between-ifnar2-and-dpp9-genes-single-nucleotide-polymorphisms-frequency-with-covid-19-severity-in-iranian-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155792.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">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Reduction of Plants Biodiversity in Hyrcanian Forest by Coal Mining Activities </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Tavakoli">Mahsa Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Hojjati"> Seyed Mohammad Hojjati</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Kooch"> Yahya Kooch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considering that coal mining is one of the important industrial activities, it may cause damages to environment. According to the author’s best knowledge, the effect of traditional coal mining activities on plant biodiversity has not been investigated in the Hyrcanian forests. Therefore, in this study, the effect of coal mining activities on vegetation and tree diversity was investigated in Hyrcanian forest, North Iran. After filed visiting and determining the mine, 16 plots (20×20 m<sup>2</sup>) were established by systematic-randomly (60×60 m<sup>2</sup>) in an area of 4 ha (200×200 m<sup>2</sup>-mine entrance placed at center). An area adjacent to the mine was not affected by the mining activity, and it is considered as the control area. In each plot, the data about trees such as number and type of species were recorded. The biodiversity of vegetation cover was considered 5 square sub-plots (1 m<sup>2</sup>) in each plot. PAST software and Ecological Methodology were used to calculate Biodiversity indices. The value of Shannon Wiener and Simpson diversity indices for tree cover in control area (1.04<span dir="RTL">±</span>0.34 and 0.62<span dir="RTL">±</span>0.20) was significantly higher than mining area (0.78<span dir="RTL">±</span>0.27 and 0.45<span dir="RTL">±</span>0.14). The value of evenness indices for tree cover in the mining area was significantly lower than that of the control area. The value of Shannon Wiener and Simpson diversity indices for vegetation cover in the control area (1.37<span dir="RTL">±</span>0.06 and 0.69<span dir="RTL">±</span>0.02) was significantly higher than the mining area (1.02<span dir="RTL">±</span>0.13 and 0.50<span dir="RTL">±</span>0.07). The value of evenness index in the control area was significantly higher than the mining area. Plant communities are a good indicator of the changes in the site. Study about changes in vegetation biodiversity and plant dynamics in the degraded land can provide necessary information for forest management and reforestation of these areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vegetation%20biodiversity" title="vegetation biodiversity">vegetation biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20composition" title=" species composition"> species composition</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20coal%20mining" title=" traditional coal mining"> traditional coal mining</a>, <a href="https://publications.waset.org/abstracts/search?q=Caspian%20forest" title=" Caspian forest"> Caspian forest</a> </p> <a href="https://publications.waset.org/abstracts/100549/reduction-of-plants-biodiversity-in-hyrcanian-forest-by-coal-mining-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100549.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">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Lead and Cadmium Spatial Pattern and Risk Assessment around Coal Mine in Hyrcanian Forest, North Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Tavakoli">Mahsa Tavakoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Hojjati"> Seyed Mohammad Hojjati</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Kooch"> Yahya Kooch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of coal mining activities on lead and cadmium concentrations and distribution in soil was investigated in Hyrcanian forest, North Iran. 16 plots (20×20 m<sup>2</sup>) were established by systematic-randomly (60×60 m<sup>2</sup>) in an area of 4 ha (200×200 m<sup>2</sup>-mine entrance placed at center). An area adjacent to the mine was not affected by the mining activity; considered as the controlled area. In order to investigate soil lead and cadmium concentration, one sample was taken from the 0-10 cm in each plot. To study the spatial pattern of soil properties and lead and cadmium concentrations in the mining area, an area of 80×80m<sup>2</sup> (the mine as the center) was considered and 80 soil samples were systematic-randomly taken (10 m intervals). Geostatistical analysis was performed via Kriging method and GS<sup>+ </sup>software (version 5.1). In order to estimate the impact of coal mining activities on soil quality, pollution index was measured. Lead and cadmium concentrations were significantly higher in mine area (Pb: 10.97<strong><span dir="RTL">±</span></strong>0.30, Cd: 184.47<strong><span dir="RTL">±</span></strong>6.26 mg.kg<sup>-1</sup>) in comparison to control area (Pb: 9.42<strong><span dir="RTL">±</span></strong>0.17, Cd: 131.71<strong><span dir="RTL">±</span></strong>15.77 mg.kg<sup>-1</sup>). The mean values of the PI index indicate that Pb (1.16) and Cd (1.77) presented slightly polluted. Results of the NIPI index showed that Pb (1.44) and Cd (2.52) presented slight pollution and moderate pollution respectively. Results of variography and kriging method showed that it is possible to prepare interpolation maps of lead and cadmium around the mining areas in Hyrcanian forest. According to results of pollution and risk assessments, forest soil was contaminated by heavy metals (lead and cadmium); therefore, using reclamation and remediation techniques in these areas is necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traditional%20coal%20mining" title="traditional coal mining">traditional coal
