Hopefully, there will be enough studies about athletics performance in the terms of addiction-related genetic markers in the future. In the present study, we intended to investigate the Receptor-2 Gene (<em>DRD2</em>) rs1800497, which is related to brain dopaminergic system. 10 sprinter and 10 endurance athletes were enrolled in the study. Real-Time Polymerase Chain Reaction method was used for genotyping. According to results, A1A1, A1A2 and A2A2 genotypes in athletes were 0 (%0), 3 (%15) and 17 (%85). A1A1 genotype was not found and A2 allele was counted as the dominating allele in our cohort. These findings show that dopaminergic mechanism effects on sport genetic may be explained by the polygenic and multifactorial view. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=addiction" title="addiction">addiction</a>, <a href="https://publications.waset.org/abstracts/search?q=athletic%20performance" title=" athletic performance"> athletic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=sport%20genetics" title=" sport genetics"> sport genetics</a> </p> <a href="https://publications.waset.org/abstracts/88795/the-effect-of-dopamine-d2-receptor-taq-a1-allele-on-sprinter-and-endurance-athlete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88795.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">20</span> Investigation of Comfort Properties of Knitted Fabrics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Karahan">Mehmet Karahan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nevin%20Karahan"> Nevin Karahan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water and air permeability and thermal resistance of fabrics are the important attributes which strongly influence the thermo-physiological comfort properties of sportswear fabrics in different environmental conditions. In this work, terry and fleece fabrics were developed by varying the fiber content and areal density of fabrics. Further, the thermo-physical properties, including air permeability, water vapor permeability, and thermal resistance, of the developed fabrics were analyzed before and after washing. The multi-response optimization of thermo-physiological comfort properties was done by using principal component analysis (PCA) and Taguchi signal to noise ratio (PCA-S/N ratio) for optimal properties. It was found that the selected parameters resulted in a significant effect on thermo-physiological comfort properties of knitted fabrics. The PCA analysis showed that before wash, 100% cotton fabric with an aerial weight of 220 g.m⁻² gave optimum values of thermo-physiological comfort. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermo-physiological%20comfort" title="thermo-physiological comfort">thermo-physiological comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=fleece%20knitted%20fabric" title=" fleece knitted fabric"> fleece knitted fabric</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20permeability" title=" air permeability"> air permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20vapor%20transmission" title=" water vapor transmission"> water vapor transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton%2Fpolyester" title=" cotton/polyester"> cotton/polyester</a> </p> <a href="https://publications.waset.org/abstracts/147190/investigation-of-comfort-properties-of-knitted-fabrics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147190.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">117</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> Structural Breaks, Asymmetric Effects and Long Memory in the Volatility of Turkey Stock Market </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serpil%20T%C3%BCrky%C4%B1lmaz">Serpil Türkyılmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Bal%C4%B1bey"> Mesut Balıbey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, long memory properties in volatility of Turkey Stock Market are being examined through the FIGARCH, FIEGARCH and FIAPARCH models under different distribution assumptions as normal and skewed student-t distributions.

Characterization of the catalysts was verified by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR). The effect of catalysts on biodiesel content from jatropha oil was studied under supercritical conditions. The results showed that ZnO/γ-Al₂O₃ was the superior catalyst for jatropha oil with 98.05% biodiesel under reaction conditions of 7 min reaction time, 1:40 oil to methanol molar ratio, 6 wt% of catalyst loading, 90 bar of reaction pressure, and 300 °C of reaction temperature, compared to 95.50% with La₂O₃/γ-Al₂O₃ at the same parameters. For this study, ZnO/γ-Al₂O₃ was the most suitable catalyst due to performance and cost considerations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title="biodiesel">biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneous%20catalyst" title=" heterogeneous catalyst"> heterogeneous catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=jatropha%20oil" title=" jatropha oil"> jatropha oil</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20methanol" title=" supercritical methanol"> supercritical methanol</a>, <a href="https://publications.waset.org/abstracts/search?q=transesterification" title=" transesterification"> transesterification</a> </p> <a href="https://publications.waset.org/abstracts/162036/supercritical-methanol-for-biodiesel-production-from-jatropha-oil-in-the-presence-of-heterogeneous-catalysts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162036.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">88</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> Experimental Analysis of Electrical Energy Producing Using the Waste Heat of Exhaust Gas by the Help of Thermoelectric Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dilek%20Ozlem%20Esen">Dilek Ozlem Esen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Kaya"> Mesut Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focus of this study is to analyse the results of heat recovery from exhaust gas which is produced by an internal combustion engine (ICE). To obtain a small amount of energy, an exhaust system which is suitable for recovery waste heat has been constructed. Totally 27 TEGs have been used to convert from the heat to electric energy. By producing a small amount of this energy by the help of thermoelectric generators can reduce engine loads thus decreasing pollutant emissions, fuel consumption, and CO2. This case study is conducted in an effort to better understand and improve the performance of thermoelectric heat recovery systems for automotive use. As a result of this study, 0,45 A averaged current rate, 13,02 V averaged voltage rate and 5,8 W averaged electrical energy have been produced in a five hours operation time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermoelectric" title="thermoelectric">thermoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=peltier" title=" peltier"> peltier</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelectric%20generator%20%28TEG%29" title=" thermoelectric generator (TEG)"> thermoelectric generator (TEG)</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust" title=" exhaust"> exhaust</a>, <a href="https://publications.waset.org/abstracts/search?q=cogeneration" title=" cogeneration"> cogeneration</a> </p> <a href="https://publications.waset.org/abstracts/29471/experimental-analysis-of-electrical-energy-producing-using-the-waste-heat-of-exhaust-gas-by-the-help-of-thermoelectric-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29471.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">654</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> Churn Prediction for Telecommunication Industry Using Artificial Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ulas%20Vural">Ulas Vural</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Ergun%20Okay"> M.

The large amount of customer data owned by the service providers is suitable for analysis by machine learning methods. In this study, expenditure data of customers are analyzed by using an artificial neural network (ANN). The ANN model is applied to the data of customers with different billing duration. The proposed model successfully predicts the churn probabilities at 83% accuracy for only three months expenditure data and the prediction accuracy increases up to 89% when the nine month data is used. The experiments also show that the accuracy of ANN model increases on an extended feature set with information of the changes on the bill amounts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=customer%20relationship%20management" title="customer relationship management">customer relationship management</a>, <a href="https://publications.waset.org/abstracts/search?q=churn%09prediction" title=" churn prediction"> churn prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=telecom%20industry" title=" telecom industry"> telecom industry</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title=" artificial neural networks"> artificial neural networks</a> </p> <a href="https://publications.waset.org/abstracts/126999/churn-prediction-for-telecommunication-industry-using-artificial-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126999.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Natural Radioactivity in Foods Consumed in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Kam">E.

For this purpose, 48 different foods samples were collected from different land parcels throughout the country. All samples were analyzed to designate both gross alpha and gross beta radioactivities and the radionuclides’ concentrations. The gross alpha radioactivities were measured as below 1 Bq kg<sup>-1</sup> in most of the samples, some of them being due to the detection limit of the counting system. The gross beta radioactivity levels ranged from 1.8 Bq kg<sup>-1</sup> to 453 Bq kg<sup>-1</sup>, larger levels being observed in leguminous seeds while the highest level being in haricot bean. The concentrations of natural radionuclides in the foodstuffs were investigated by the method of gamma spectroscopy. High levels of <sup>40</sup>K were measured in all the samples, the highest activities being again in leguminous seeds. Low concentrations of <sup>238</sup>U and <sup>226</sup>Ra were found in some of the samples, which are comparable to the reported results in the literature.

An experimental program was conducted by using the central composite design method. Alkali solution-slag ratio was kept constant at 0.53 in all mixture. The effects of the independent parameters were characterized and analyzed by using statistically significant quadratic regression models on the measured properties (dependent parameters). The proposed regression models are valid for AAS concretes with the SC from 0.1% to 7.5%, SM from 0.4 to 3.2, CT from 20 °C to 94 °C and TC from 1.2 hours to 25 hours. The results of test and analysis indicate that the most effective parameter for the compressive strength, chloride ion permeability and water absorption capacity is the sodium concentration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkali%20activation" title="alkali activation">alkali activation</a>, <a href="https://publications.waset.org/abstracts/search?q=slag" title=" slag"> slag</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20chloride%20permeability" title=" rapid chloride permeability"> rapid chloride permeability</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorption%20capacity" title=" water absorption capacity"> water absorption capacity</a> </p> <a href="https://publications.waset.org/abstracts/54620/optimum-design-of-alkali-activated-slag-concretes-for-low-chloride-ion-permeability-and-water-absorption-capacity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54620.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">312</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> Key Performance Indicators and the Model for Achieving Digital Inclusion for Smart Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Obaed%20Mahmod">Khalid Obaed Mahmod</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Cevik"> Mesut Cevik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The term smart city has appeared recently and was accompanied by many definitions and concepts, but as a simplified and clear definition, it can be said that the smart city is a geographical location that has gained efficiency and flexibility in providing public services to citizens through its use of technological and communication technologies, and this is what distinguishes it from other cities. Smart cities connect the various components of the city through the main and sub-networks in addition to a set of applications and thus be able to collect data that is the basis for providing technological solutions to manage resources and provide services. The basis of the work of the smart city is the use of artificial intelligence and the technology of the Internet of Things. The work presents the concept of smart cities, the pillars, standards, and evaluation indicators on which smart cities depend, and the reasons that prompted the world to move towards its establishment. It also provides a simplified hypothetical way to measure the ideal smart city model by defining some indicators and key pillars, simulating them with logic circuits, and testing them to determine if the city can be considered an ideal smart city or not. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factors" title="factors">factors</a>, <a href="https://publications.waset.org/abstracts/search?q=indicators" title=" indicators"> indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=logic%20gates" title=" logic gates"> logic gates</a>, <a href="https://publications.waset.org/abstracts/search?q=pillars" title=" pillars"> pillars</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a> </p> <a href="https://publications.waset.org/abstracts/150374/key-performance-indicators-and-the-model-for-achieving-digital-inclusion-for-smart-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150374.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">150</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> A Periodogram-Based Spectral Method Approach: The Relationship between Tourism and Economic Growth in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mesut%20BALIBEY">Mesut BALIBEY</a>, <a href="https://publications.waset.org/abstracts/search?q=Serpil%20T%C3%9CRKYILMAZ"> Serpil TÜRKYILMAZ</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A popular topic in the econometrics and time series area is the cointegrating relationships among the components of a nonstationary time series. Engle and Granger’s least squares method and Johansen’s conditional maximum likelihood method are the most widely-used methods to determine the relationships among variables. Furthermore, a method proposed to test a unit root based on the periodogram ordinates has certain advantages over conventional tests. Periodograms can be calculated without any model specification and the exact distribution under the assumption of a unit root is obtained. For higher order processes the distribution remains the same asymptotically. In this study, in order to indicate advantages over conventional test of periodograms, we are going to examine a possible relationship between tourism and economic growth during the period 1999:01-2010:12 for Turkey by using periodogram method, Johansen’s conditional maximum likelihood method, Engle and Granger’s ordinary least square method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cointegration" title="cointegration">cointegration</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=periodogram%20ordinate" title=" periodogram ordinate"> periodogram ordinate</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism" title=" tourism"> tourism</a> </p> <a href="https://publications.waset.org/abstracts/14439/a-periodogram-based-spectral-method-approach-the-relationship-between-tourism-and-economic-growth-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14439.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">270</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> Media Coverage of the Turkish Armenian Journalist Hrant Dink Assassination: The Analysis of Media News in the Aftermath of the Assassination </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nusret%20Mesut%20Sahin">Nusret Mesut Sahin </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hrant Dink, a prominent Turkish-Armenian journalist, and editor-in-chief of the bilingual Turkish-Armenian newspaper Agos, was assassinated in Istanbul on January 19th, 2007 by a nationalist extremist, Ogun Samast.

The findings of this research suggested that Dink’s assassination wounded Turkey’s image as a democratic country. It has also been found that the Turkish media focused on security forces and their responsibility in Dink’s assassination, whereas international media focused more on the Article 301 of the Turkish penal code, freedom of expression, and atrocities against the Armenians during the Ottoman rule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hrant%20Dink" title="Hrant Dink">Hrant Dink</a>, <a href="https://publications.waset.org/abstracts/search?q=Armenian" title=" Armenian"> Armenian</a>, <a href="https://publications.waset.org/abstracts/search?q=journalist" title=" journalist"> journalist</a>, <a href="https://publications.waset.org/abstracts/search?q=assassination" title=" assassination "> assassination </a> </p> <a href="https://publications.waset.org/abstracts/93285/media-coverage-of-the-turkish-armenian-journalist-hrant-dink-assassination-the-analysis-of-media-news-in-the-aftermath-of-the-assassination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93285.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">152</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> Factors Affecting Residential Satisfaction in Low-Income Housing: Case Study of War College Housing in Gwarinpa Estate-Abuja, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulmajeed%20Mustapha">Abdulmajeed Mustapha</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Sahin"> Murat Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebru%20Karahan"> Ebru Karahan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Low-income housing for poor people in urban areas is a global challenge, especially in developing countries. The quality of construction of mass housing is oftentimes compromised, thus resulting in a housing deficit, thereby affecting the residential satisfaction of users. This research analyses the various factors affecting residential satisfaction in War College Housing Estate, Abuja, Nigeria. These were investigated using parameters such as environmental characteristics and public amenities such as public benefits, safety/security, and sociodemographic characteristics. The study adopted a quantitative approach for the data gathering through literature reviews within the topic’s scope. The survey was conducted between April to May 2021 using a questionnaire form that was distributed to household members, onsite analysis within the selected housing project, and interviews with a few professionals within the field of this research. Data gathered from the survey and analysis on housing and sociodemographic characteristics, amongst others, were acquired through the means of interviews and site surveys of the selected Housing Estate. Findings from the various characteristics determining satisfaction revealed that residents had varying levels of satisfaction, ranging from a scale of satisfied to dissatisfied. It is recommended that the government come up with policies that will not only make the environment clean and safe but also make sure that the needs of the people who live there are taken into account. This will help the people who live there be more satisfied with their homes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=residential%20satisfaction" title="residential satisfaction">residential satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=neighborhood%20satisfaction" title=" neighborhood satisfaction"> neighborhood satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=low-income%20housing" title=" low-income housing"> low-income housing</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-demographic%20characteristics" title=" socio-demographic characteristics"> socio-demographic characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/150708/factors-affecting-residential-satisfaction-in-low-income-housing-case-study-of-war-college-housing-in-gwarinpa-estate-abuja-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150708.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">97</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> An Experimental Study on Heat and Flow Characteristics of Water Flow in Microtube</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20K%C3%BC%C3%A7%C3%BCkak%C3%A7a">Zeynep Küçükakça</a>, <a href="https://publications.waset.org/abstracts/search?q=Nezaket%20Parlak"> Nezaket Parlak</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20G%C3%BCr"> Mesut Gür</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahsin%20Engin"> Tahsin Engin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20K%C3%BC%C3%A7%C3%BCk"> Hasan Küçük</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current research, the single phase fluid flow and heat transfer characteristics are experimentally investigated. The experiments are conducted to cover transition zone for the Reynolds numbers ranging from 100 to 4800 by fused silica and stainless steel microtubes having diameters of 103-180 µm. The applicability of the Logarithmic Mean Temperature Difference (LMTD) method is revealed and an experimental method is developed to calculate the heat transfer coefficient. Heat transfer is supplied by a water jacket surrounding the microtubes and heat transfer coefficients are obtained by LMTD method. The results are compared with data obtained by the correlations available in the literature in the study. The experimental results indicate that the Nusselt numbers of microtube flows do not accord with the conventional results when the Reynolds number is lower than 1000. After that, the Nusselt number approaches the conventional theory prediction. Moreover, the scaling effects in micro scale such as axial conduction, viscous heating and entrance effects are discussed. On the aspect of fluid characteristics, the friction factor is well predicted with conventional theory and the conventional friction prediction is valid for water flow through microtube with a relative surface roughness less than about 4 %. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microtube" title="microtube">microtube</a>, <a href="https://publications.waset.org/abstracts/search?q=laminar%20flow" title=" laminar flow"> laminar flow</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20factor" title=" friction factor"> friction factor</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=LMTD%20method" title=" LMTD method"> LMTD method</a> </p> <a href="https://publications.waset.org/abstracts/34123/an-experimental-study-on-heat-and-flow-characteristics-of-water-flow-in-microtube" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34123.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">460</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> Understanding the Motivations behind the Assassination of Turkish Armenian Journalist, Hrant Dink</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nusret%20Mesut%20Sahin">Nusret Mesut Sahin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hrant Dink, a prominent Turkish-Armenian journalist, and editor-in-chief of the bilingual Turkish-Armenian newspaper Agos was assassinated in Istanbul on January 19th, 2007 by a nationalist extremist, Ogun Samast.

It has been argued that the suffocating atmosphere created by the Turkish news media targeting Mr. Dink made him a target of an extremist Turkish juvenile. This study analyzes the media news to understand and explain why Hrant Dink became the target of a nationalist extremist. In this research, content analysis of news articles (N= 170) is conducted to identify whether there is a link between hate speech against Hrant Dink in the Turkish media and his assassination. The content of the newspaper articles is categorized and coded according to the hate language being used. The analysis suggested that Turkish media paved the way for Dink’s assassination. Hate speech against Hrant Dink on the media had risen gradually before the assassination. The study also found that the number of news stories covering hate speech and racist discourse against non-Muslim citizens of Turkey also increased dramatically before the assassination. Therefore, hate speech against minorities in media narratives and news reports should be monitored, and political figures or leaders of social groups who are targeted by some media outlets should be protected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hrant%20Dink" title="Hrant Dink">Hrant Dink</a>, <a href="https://publications.waset.org/abstracts/search?q=assassination" title=" assassination"> assassination</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20Armenian%20journalist" title=" Turkish Armenian journalist"> Turkish Armenian journalist</a>, <a href="https://publications.waset.org/abstracts/search?q=media" title=" media"> media</a> </p> <a href="https://publications.waset.org/abstracts/91256/understanding-the-motivations-behind-the-assassination-of-turkish-armenian-journalist-hrant-dink" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91256.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">159</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> Gender Differences in Communication Styles: An Analysis of the Language of Earnings Conference Calls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chiara%20De%20Amicis">Chiara De Amicis</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Falconieri"> Sonia Falconieri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Tastan"> Mesut Tastan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we analyze the language employed by Chief Executive Officers (CEOs) and Chief Financial Officers (CFOs) during earnings conference calls from a gender perspective. We find evidences that conference calls held by female CEOs and/or CFOs exhibit a higher level of optimism compared to conference calls held by male CEOs and/or CFOs. Moreover, female managers tend to present and discuss firm performances with less vagueness as compared to their male colleagues. We then observe the market reaction around each earnings conference call: while manager optimism is perceived as a good signal by investors, manager vagueness significantly dampens the market reaction around the call. Whether the gender of the CEO and/or the CFO delivering the conference call affects investors’ perceptions about the firm performance is still an open question. Some evidences show that the language employed by female managers conveys more valuable information for market participants as compared to the language employed by their male counterparts. This study contributes to a growing literature in finance and accounting that uses textual analysis to assess the informativeness of corporate disclosure. To our knowledge, this is the first paper that aims at answering the question whether the gender of firm’s top managers does matter when it comes to assess the informativeness of corporate spoken communication. We believe that our results will be of relevance for future research in the field. Moreover, our evidence may be used in support of the debate if a larger participation by women in the management of companies should be encouraged or not. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conference%20calls" title="conference calls">conference calls</a>, <a href="https://publications.waset.org/abstracts/search?q=even%20study" title=" even study"> even study</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20reaction" title=" market reaction"> market reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=textual%20analysis" title=" textual analysis"> textual analysis</a> </p> <a href="https://publications.waset.org/abstracts/93086/gender-differences-in-communication-styles-an-analysis-of-the-language-of-earnings-conference-calls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93086.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">194</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> Effects of Nano-Coating on the Mechanical Behavior of Nanoporous Metals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yunus%20Onur%20Yildiz">Yunus Onur Yildiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Kirca"> Mesut Kirca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, mechanical properties of a nanoporous metal coated with a different metallic material are studied through a new atomistic modelling technique and molecular dynamics (MD) simulations. This new atomistic modelling technique is based on the Voronoi tessellation method for the purpose of geometric representation of the ligaments. With the proposed technique, atomistic models of nanoporous metals which have randomly oriented ligaments with non-uniform mass distribution along the ligament axis can be generated by enabling researchers to control both ligament length and diameter. Furthermore, by the utilization of this technique, atomistic models of coated nanoporous materials can be numerically obtained for further mechanical or thermal characterization. In general, this study consists of two stages. At the first stage, we use algorithms developed for generating atomic coordinates of the coated nanoporous material. In this regard, coordinates of randomly distributed points are determined in a controlled way to be employed in the establishment of the Voronoi tessellation, which results in randomly oriented and intersected line segments. Then, line segment representation of the Voronoi tessellation is transformed to atomic structure by a special process. This special process includes generation of non-uniform volumetric core region in which atoms can be generated based on a specific crystal structure. As an extension, this technique can be used for coating of nanoporous structures by creating another volumetric region encapsulating the core region in which atoms for the coating material are generated. The ultimate goal of the study at this stage is to generate atomic coordinates that can be employed in the MD simulations of randomly organized coated nanoporous structures. At the second stage of the study, mechanical behavior of the coated nanoporous models is investigated by examining deformation mechanisms through MD simulations.

Thus, there is very much that can be learned from these organisms on the practical and evolutionary levels, further resembling Darwin's words, “It is not the strongest of the species that survives, nor the most intelligent, but the one most responsive to change”. The ‘stem cell’ notion highlights a cell that has the ability to continuously divide and differentiate into various progenitors and daughter cells. In vertebrates, adult stem cells are rare cells defined as lineage-restricted (multipotent at best) with tissue or organ-specific activities that are located in defined niches and further regulate the machinery of homeostasis, repair, and regeneration. They are usually categorized by their morphology, tissue of origin, plasticity, and potency. The above description not always holds when comparing the vertebrates with marine invertebrates’ stem cells that display wider ranges of plasticity and diversity at the taxonomic and the cellular levels. While marine/aquatic invertebrates stem cells (MISC) have recently raised more scientific interest, the know-how is still behind the attraction they deserve. MISC, not only are highly potent but, in many cases, are abundant (e.g., 1/3 of the entire animal cells), do not locate in permanent niches, participates in delayed-aging and whole-body regeneration phenomena, the knowledge of which can be clinically relevant. Moreover, they have massive hidden potential for the discovery of new bioactive molecules that can be used for human health (antitumor, antimicrobial) and biotechnology. The MARISTEM COST action (Stem Cells of Marine/Aquatic Invertebrates: From Basic Research to Innovative Applications) aims to connect the European fragmented MISC community. Under this scientific umbrella, the action conceptualizes the idea for adult stem cells that do not share many properties with the vertebrates’ stem cells, organizes meetings, summer schools, and workshops, stimulating young researchers, supplying technical and adviser support via short-term scientific studies, making new bridges between the MISC community and biomedical disciplines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquatic%2Fmarine%20invertebrates" title="aquatic/marine invertebrates">aquatic/marine invertebrates</a>, <a href="https://publications.waset.org/abstracts/search?q=adult%20stem%20cell" title=" adult stem cell"> adult stem cell</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20cultures" title=" cell cultures"> cell cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=bioactive%20molecules" title=" bioactive molecules"> bioactive molecules</a> </p> <a href="https://publications.waset.org/abstracts/143573/maristem-a-cost-action-focused-on-stem-cells-of-aquatic-invertebrates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143573.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">169</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Nanoporous Metals Reinforced with Fullerenes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deni%CC%87z%20Ezgi%CC%87%20G%C3%BClmez">Deni̇z Ezgi̇ Gülmez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Kirca"> Mesut Kirca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanoporous (np) metals have attracted considerable attention owing to their cellular morphological features at atomistic scale which yield ultra-high specific surface area awarding a great potential to be employed in diverse applications such as catalytic, electrocatalytic, sensing, mechanical and optical. As one of the carbon based nanostructures, fullerenes are also another type of outstanding nanomaterials that have been extensively investigated due to their remarkable chemical, mechanical and optical properties. In this study, the idea of improving the mechanical behavior of nanoporous metals by inclusion of the fullerenes, which offers a new metal-carbon nanocomposite material, is examined and discussed. With this motivation, tensile mechanical behavior of nanoporous metals reinforced with carbon fullerenes is investigated by classical molecular dynamics (MD) simulations. Atomistic models of the nanoporous metals with ultrathin ligaments are obtained through a stochastic process simply based on the intersection of spherical volumes which has been used previously in literature. According to this technique, the atoms within the ensemble of intersecting spherical volumes is removed from the pristine solid block of the selected metal, which results in porous structures with spherical cells. Following this, fullerene units are added into the cellular voids to obtain final atomistic configurations for the numerical tensile tests. Several numerical specimens are prepared with different number of fullerenes per cell and with varied fullerene sizes. LAMMPS code was used to perform classical MD simulations to conduct uniaxial tension experiments on np models filled by fullerenes. The interactions between the metal atoms are modeled by using embedded atomic method (EAM) while adaptive intermolecular reactive empirical bond order (AIREBO) potential is employed for the interaction of carbon atoms. Furthermore, atomic interactions between the metal and carbon atoms are represented by Lennard-Jones potential with appropriate parameters. In conclusion, the ultimate goal of the study is to present the effects of fullerenes embedded into the cellular structure of np metals on the tensile response of the porous metals. The results are believed to be informative and instructive for the experimentalists to synthesize hybrid nanoporous materials with improved properties and multifunctional characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fullerene" title="fullerene">fullerene</a>, <a href="https://publications.waset.org/abstracts/search?q=intersecting%20spheres" title=" intersecting spheres"> intersecting spheres</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamic" title=" molecular dynamic"> molecular dynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoporous%20metals" title=" nanoporous metals"> nanoporous metals</a> </p> <a href="https://publications.waset.org/abstracts/47462/nanoporous-metals-reinforced-with-fullerenes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47462.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">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> The Relationship between Self-Injurious Behavior and Manner of Death</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sait%20Ozsoy">Sait Ozsoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Hacer%20Yasar%20Teke"> Hacer Yasar Teke</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Dalgic"> Mustafa Dalgic</a>, <a href="https://publications.waset.org/abstracts/search?q=Cetin%20Ketenci"> Cetin Ketenci</a>, <a href="https://publications.waset.org/abstracts/search?q=Ertugrul%20Gok"> Ertugrul Gok</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenan%20Karbeyaz"> Kenan Karbeyaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Azem%20Irez"> Azem Irez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesut%20Akyol"> Mesut Akyol</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-mutilating behavior or self-injury behavior (SIB) is defined as: intentional harm to one’s body without intends to commit suicide”. SIB cases are commonly seen in psychiatry and forensic medicine practices. Despite variety of SIB methods, cuts in the skin is the most common (70-97%) injury in this group of patients. Subjects with SIB have one or more other comorbidities which include depression, anxiety, depersonalization, and feeling of worthlessness, borderline personality disorder, antisocial behaviors, and histrionic personality. These individuals feel a high level of hostility towards themselves and their surroundings. Researches have also revealed a strong relationship between antisocial personality disorder, criminal behavior, and SIB. This study has retrospectively evaluated 6,599 autopsy cases performed at forensic medicine institutes of six major cities (Ankara, Izmir, Diyarbakir, Erzurum, Trabzon, Eskisehir) of Turkey in 2013. The study group consisted of all cases with SIB findings (psychopathic cuts, cigarette burns, scars, and etc.). The relationship between causes of death in the study group (SIB subjects) and the control group was investigated. The control group was created from subjects without signs of SIB. Mann-Whitney U test was used for age variables and Chi-square test for categorical variables. Multinomial logistic regression analysis was used in order to analyze group differences in respect to manner of death (natural, accident, homicide, suicide) and analysis of risk factors associated with each group was determined by the Binomial logistic regression analysis. This study used SPSS statistics 15.0 for all its statistical and calculation needs. The statistical significance was p <0.05. There was no significant difference between accidental and natural death among the groups (p=0.737). Also there was a unit increase in number of cuts in psychopathic group while number of accidental death decreased (95% CI: 0.941-0.993) by 0.967 times (p=0.015). In contrast, there was a significant difference between suicidal and natural death (p<0.001), and also between homicidal and natural death (p=0.025). SIB is often seen with borderline and antisocial personality disorder but may be associated with many psychiatric illnesses. Studies have shown a relationship between antisocial personality disorders with criminal behavior and SIB with suicidal behavior. In our study, rate of suicide, murder and intoxication was higher compared to the control group. It could be concluded that SIB can be used as a predictor of possibility of one’s harm to him/herself and other people. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autopsy" title="autopsy">autopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=cause%20of%20death" title=" cause of death"> cause of death</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20science" title=" forensic science"> forensic science</a>, <a href="https://publications.waset.org/abstracts/search?q=self-injury%20behaviour" title=" self-injury behaviour"> self-injury behaviour</a> </p> <a href="https://publications.waset.org/abstracts/28973/the-relationship-between-self-injurious-behavior-and-manner-of-death" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28973.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">510</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Lifespan Assessment of the Fish Crossing System of Itaipu Power Plant (Brazil/Paraguay) Based on the Reaching of Its Sedimentological Equilibrium Computed by 3D Modeling and Churchill Trapping Efficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Braga%20Mendes">Anderson Braga Mendes</a>, <a href="https://publications.waset.org/abstracts/search?q=Wallington%20Felipe%20de%20Almeida"> Wallington Felipe de Almeida</a>, <a href="https://publications.waset.org/abstracts/search?q=Cicero%20Medeiros%20da%20Silva"> Cicero Medeiros da Silva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to assess the lifespan of the fish transposition system of the Itaipu Power Plant (Brazil/Paraguay) by using 3D hydrodynamic modeling and Churchill trapping effiency in order to identify the sedimentological equilibrium configuration in the main pond of the Piracema Channel, which is part of a 10 km hydraulic circuit that enables fish migration from downstream to upstream (and vice-versa) the Itaipu Dam, overcoming a 120 m water drop. For that, bottom data from 2002 (its opening year) and 2015 were collected and analyzed, besides bed material at 12 stations to the purpose of identifying their granulometric profiles. The Shields and Yalin and Karahan diagrams for initiation of motion of bed material were used to determine the critical bed shear stress for the sedimentological equilibrium state based on the sort of sediment (grain size) to be found at the bottom once the balance is reached. Such granulometry was inferred by analyzing the grosser material (fine and medium sands) which inflows the pond and deposits in its backwater zone, being adopted a range of diameters within the upper and lower limits of that sand stratification. The software Delft 3D was used in an attempt to compute the bed shear stress at every station under analysis. By modifying the input bathymetry of the main pond of the Piracema Channel so as to the computed bed shear stress at each station fell within the intervals of acceptable critical stresses simultaneously, it was possible to foresee the bed configuration of the main pond when the sedimentological equilibrium is reached. Under such condition, 97% of the whole pond capacity will be silted, and a shallow water course with depths ranging from 0.2 m to 1.5 m will be formed; in 2002, depths ranged from 2 m to 10 m. Out of that water path, the new bottom will be practically flat and covered by a layer of water 0.05 m thick. Thus, in the future the main pond of the Piracema Channel will lack its purpose of providing a resting place for migrating fish species, added to the fact that it may become an insurmountable barrier for medium and large sized specimens. Everything considered, it was estimated that its lifespan, from the year of its opening to the moment of the sedimentological equilibrium configuration, will be approximately 95 years–almost half of the computed lifespan of Itaipu Power Plant itself. However, it is worth mentioning that drawbacks concerning the silting in the main pond will start being noticed much earlier than such time interval owing to the reasons previously mentioned. <p
