Two words are selected to find their associated publications in IEEE scholar database. Both of keywords are entered individually for the years 2002, 2012, and 2016 on the database to identify the preferred subjects of researchers in same years. We have classified closer research fields after searching and listing. Three years (2002, 2012, and 2016) have been investigated to figure out progress in specified time intervals. The first one is assumed as the initial progress in between 2002-2012, and the second one is in 2012-2016 that is fast development duration. We have found very interesting and beneficial results to understand the scholars’ research field preferences for a decade. This information will be highly desirable in smart city-based research purposes consisting of 3D and vehicle-related issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vehicle" title="Vehicle">Vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional" title=" three-dimensional"> three-dimensional</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=scholarly%20search" title=" scholarly search"> scholarly search</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic" title=" semantic"> semantic</a> </p> <a href="https://publications.waset.org/abstracts/75968/3d-vehicle-associated-research-fields-for-smart-city-via-semantic-search-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">329</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Risk Assessment for Aerial Package Delivery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haluk%20Eren">Haluk Eren</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%9Cmit%20%C3%87elik"> Ümit Çelik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent developments in unmanned aerial vehicles (UAVs) have begun to attract intense interest. UAVs started to use for many different applications from military to civilian use. Some online retailer and logistics companies are testing the UAV delivery. UAVs have great potentials to reduce cost and time of deliveries and responding to emergencies in a short time. Despite these great positive sides, just a few works have been done for routing of UAVs for package deliveries. As known, transportation of goods from one place to another may have many hazards on delivery route due to falling hazards that can be exemplified as ground objects or air obstacles. This situation refers to wide-range insurance concept. For this reason, deliveries that are made with drones get into the scope of shipping insurance. On the other hand, air traffic was taken into account in the absence of unmanned aerial vehicle. But now, it has been a reality for aerial fields. In this study, the main goal is to conduct risk analysis of package delivery services using drone, based on delivery routes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerial%20package%20delivery" title="aerial package delivery">aerial package delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=insurance%20estimation" title=" insurance estimation"> insurance estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=territory%20risk%20map" title=" territory risk map"> territory risk map</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicle" title=" unmanned aerial vehicle"> unmanned aerial vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=route%20risk%20estimation" title=" route risk estimation"> route risk estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=drone%20risk%20assessment" title=" drone risk assessment"> drone risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=drone%20package%20delivery" title=" drone package delivery"> drone package delivery</a> </p> <a href="https://publications.waset.org/abstracts/75960/risk-assessment-for-aerial-package-delivery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75960.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">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Using Recyclable Steel Material in Tall Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Eren">O.

P. anatolicus is also endangered and endemic species from Turkey. In this study, concentrations of Cd, Co, Cr, Fe, Mn, Ni, Pb and Zn were determined in muscle tissue of these fish by using atomic absorption spectrophotometer. Levels of metals in the muscle tissue of all the fish specimens were compared with results of previous studies, the tolerance levels of national and international guidelines and the levels of Provisional Tolerable Weekly Intake (PTWI) limits set by FAO/WHO. Concentrations of Cd, Cr, Ni and Pb in the muscle tissue of all the fish specimens from Suğla and Beyşehir Lakes exceeded the tolerance levels of national and international guidelines. However, concentrations of Cd, Fe, Pb and Zn were below PTWI limits. Therefore, in terms of these metal levels, consumption of fresh filet of examined seven fish species (weekly up to about 300 g/person) doesn’t seem to be objectionable for human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bey%C5%9Fehir%20Lake" title="Beyşehir Lake">Beyşehir Lake</a>, <a href="https://publications.waset.org/abstracts/search?q=fish" title=" fish"> fish</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20levels" title=" metal levels"> metal levels</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%C4%9Fla%20Lake" title=" Suğla Lake"> Suğla Lake</a> </p> <a href="https://publications.waset.org/abstracts/29001/some-metal-levels-in-muscle-tissue-of-seven-fish-species-from-the-sugla-and-beysehir-lakes-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29001.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">335</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Implementation and Modeling of a Quadrotor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ersan%20Aktas">Ersan Aktas</a>, <a href="https://publications.waset.org/abstracts/search?q=Eren%20Turano%C4%9Fuz"> Eren Turanoğuz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the quad-electrical rotor driven unmanned aerial vehicle system is designed and modeled using fundamental dynamic equations. After that, mechanical, electronical and control system of the air vehicle are designed and implemented. Brushless motor speeds are altered via electronic speed controllers in order to achieve desired controllability. The vehicle's fundamental Euler angles (i.e., roll angle, pitch angle, and yaw angle) are obtained via AHRS sensor.

Quantum dots (QDs) with strong and easily tunable luminescence and high emission quantum yields have become a well-established photoluminescent nanomaterials for sensor applications. Although the majority of the reports focused on the cadmium-based QDs which have toxic effect on biological systems and eventually would cause serious environmental problems, carbon-based quantum dots (CQDs) that do not contain any toxic class elements have attracted substantial research interest in recent years. CQDs are small carbon nanostructures (less than 10 nm in size) with various unique properties and are widely-used in different fields during the last few years. In this respect, chiral nanostructures have become a promising class of materials in various areas such as pharmacology, catalysis, bioanalysis and (bio)sensor technology due to the vital importance of chirality in living systems. We herein report the synthesis of chiral CQDs with D- or L-tartaric acid as precursor materials. The optimum experimental conditions were examined and the purification procedure was performed using ethanol/water by column chromatography. The purified chiral CQDs were characterized by UV-Vis, FT-IR, XPS, PL and TEM techniques. The resultants display different photoluminescent characteristics due to the size and conformational difference. Considering the results, it can be concluded that chiral CQDs is expected to be used as optical chiral sensor in different platforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20quantum%20dots" title="carbon quantum dots">carbon quantum dots</a>, <a href="https://publications.waset.org/abstracts/search?q=chirality" title=" chirality"> chirality</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=tartaric%20acid" title=" tartaric acid"> tartaric acid</a> </p> <a href="https://publications.waset.org/abstracts/52635/chiral-carbon-quantum-dots-for-paper-based-photoluminescent-sensing-platforms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52635.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">240</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">28</span> A Comparison of the Environmental Impacts of Edible and Non-Edible Oil Crops in Biodiesel Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Halit%20Tutar">Halit Tutar</a>, <a href="https://publications.waset.org/abstracts/search?q=Omer%20Eren"> Omer Eren</a>, <a href="https://publications.waset.org/abstracts/search?q=Oguz%20Parlakay"> Oguz Parlakay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The demand for food and energy of mankind has been increasing every passing day. Renewable energy sources have been pushed to forefront since fossil fuels will be run out in the near future and their negative effects to the environment. As in every sector, the transport sector benefits from biofuel (biogas, bioethanol and biodiesel) one of the renewable energy sources as well. The edible oil crops are used in production of biodiesel. Utilizing edible oil crops as renewable energy source may raise a debate in the view of that there is a shortage in raw material of edible oil crops in Turkey. Researches related to utilization of non-edible oil crops as biodiesel raw materials have been recently increased, and especially studies related to their vegetative production and adaptation have been accelerated in Europe. In this review edible oil crops are compared to non-edible oil crops for biodiesel production in the sense of biodiesel production, some features of non-edible oil crops and their harmful emissions to environment are introduced. The data used in this study, obtained from articles, thesis, reports relevant to edible and non edible oil crops in biodiesel. <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=edible%20oil%20crops" title=" edible oil crops"> edible oil crops</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts" title=" environmental impacts"> environmental impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/66235/a-comparison-of-the-environmental-impacts-of-edible-and-non-edible-oil-crops-in-biodiesel-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66235.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">434</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> The Effect of Ethylene Propylene Diene Monomer on the Rheological Properties of Bitumen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emre%20Eren">Emre Eren</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Yigit%20Katanalp"> Burak Yigit Katanalp</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Tastan"> Murat Tastan</a>, <a href="https://publications.waset.org/abstracts/search?q=Perviz%20Ahmedzade"> Perviz Ahmedzade</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%87igdem%20Canbay%20Turkyilmaz"> Çigdem Canbay Turkyilmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Emrah%20Turkyilmaz"> Emrah Turkyilmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to investigate the mechanical and high-temperature rheological properties of Ethylene Propylene Diene Monomer (EPDM) modified bitumen.

Computer games also have become increasingly popular among people day-by-day, owing to their features based on realistic virtual environments, audio and visual features, and the roles they offer players. In the present study, the metaphors students have for computer games are investigated, as well as an effort to fill the gap in the literature. Students were asked to complete the sentence—‘Computer game is like/similar to….because….’— to determine the middle school students’ metaphorical images of the concept for ‘computer game’. The metaphors created by the students were grouped in six categories, based on the source of the metaphor. These categories were ordered as ‘computer game as a means of entertainment’, ‘computer game as a beneficial means’, ‘computer game as a basic need’, ‘computer game as a source of evil’, ‘computer game as a means of withdrawal’, and ‘computer game as a source of addiction’, according to the number of metaphors they included. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20game" title="computer game">computer game</a>, <a href="https://publications.waset.org/abstracts/search?q=metaphor" title=" metaphor"> metaphor</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20school%20students" title=" middle school students"> middle school students</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20environments" title=" virtual environments"> virtual environments</a> </p> <a href="https://publications.waset.org/abstracts/11784/metaphorical-perceptions-of-middle-school-students-regarding-computer-games" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11784.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">535</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> Designing an Online Case-Based Library for Technology Integration in Teacher Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Tevfik%20Hebebci">Mustafa Tevfik Hebebci</a>, <a href="https://publications.waset.org/abstracts/search?q=Sirin%20Kucuk"> Sirin Kucuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Celik"> Ismail Celik</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Oguz%20Akturk"> A.

The motivation has been taken from a real life case, an automotive subcontractor which has two production facilities at different cities and parts. The problem is to decide which part(s) should be produced at which facility. To the best of our knowledge, until this study, there was no scientific approach about this problem at the firm and decisions were being given intuitively. In this study, some logistic cost parameters have been defined and with these parameters a mathematical model has been constructed. Defined and collected cost parameters are handling cost of parts, shipment cost of parts and shipment cost of welding fixtures. Constructed multi-objective mathematical model aims to minimize these costs while aims to balance the workload between two locations. Results showed that defined model can give optimum solutions in reasonable computing times. Also, this result gave encouragement to develop the model with addition of new logistic cost parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automotive%20subcontract" title="automotive subcontract">automotive subcontract</a>, <a href="https://publications.waset.org/abstracts/search?q=facility%20assignment" title=" facility assignment"> facility assignment</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20costs" title=" logistic costs"> logistic costs</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-objective%20models" title=" multi-objective models"> multi-objective models</a> </p> <a href="https://publications.waset.org/abstracts/68574/a-solution-for-production-facility-assignment-an-automotive-subcontract-case" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68574.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">366</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> Investigation of Electrical, Thermal and Structural Properties on Polyacrylonitrile Nano-Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Demirsoy">N.

Polyacrylonitrile/N,N-dimethylformamide (PAN/DMF) solution has been prepared and the amount of silver nitrate has been adjusted to PAN weight. Silver nano-particles were obtained from reduction of silver ions into silver nano-particles by chemical reduction by hydrazine hydroxide (N2H5OH). The different amount of silver salt was loaded into polymer matrix to obtain polyacrylonitrile composite nano-fiber containing silver nano-particles. The effect of the amount of silver nano-particles on the properties of composite nano-fiber web was investigated. Electrical conductivity, mechanical properties, thermal properties were examined by Microtest LCR Meter 6370 (0.01 mΩ-100 MΩ), tensile tester, differential scanning calorimeter DSC (Q10) and SEM, respectively. Also, antimicrobial efficiency test (ASTM E2149-10) was done against Staphylococcus aureus bacteria. It has been seen that breaking strength, conductivity, antimicrobial effect, enthalpy during cyclization increase by use of silver nano-particles while the diameter of nano-fiber decreases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20polyacrylonitrile%20nanofiber" title="composite polyacrylonitrile nanofiber">composite polyacrylonitrile nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title=" thermal properties"> thermal properties</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/7504/investigation-of-electrical-thermal-and-structural-properties-on-polyacrylonitrile-nano-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7504.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">418</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> Bipolar Reduction and Lithic Miniaturization: Experimental Results and Archaeological Implications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Justin%20Pargeter">Justin Pargeter</a>, <a href="https://publications.waset.org/abstracts/search?q=Metin%20Eren"> Metin Eren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lithic miniaturization, the systematic production and use of small tools from small cores, was a consequential development in Pleistocene lithic technology. The bipolar reduction is an important, but often overlooked and misidentified, strategy for lithic miniaturization. This experiment addresses the role of axial bipolar reduction in processes of lithic miniaturization. The experiments answer two questions: what benefits does axial bipolar reduction provide, and can we distinguish axial bipolar reduction from freehand reduction? Our experiments demonstrate the numerous advantages of bipolar reduction in contexts of lithic miniaturization. Bipolar reduction produces more cutting edge per gram and is more economical than freehand reduction. Our cutting edge to mass values exceeds even those obtained with pressure blade production on high-quality obsidian. The experimental results show that bipolar reduction produces cutting edge quicker and is more efficient than freehand reduction. We show that bipolar reduction can be distinguished from freehand reduction with a high degree of confidence using the quantitative criteria in these experiments. These observations overturn long-held perceptions about bipolar reduction. We conclude by discussing the role of bipolar reduction in lithic miniaturization and Stone Age economics more broadly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithic%20miniaturization" title="lithic miniaturization">lithic miniaturization</a>, <a href="https://publications.waset.org/abstracts/search?q=bipolar%20reduction" title=" bipolar reduction"> bipolar reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=late%20Pleistocene" title=" late Pleistocene"> late Pleistocene</a>, <a href="https://publications.waset.org/abstracts/search?q=Southern%20Africa" title=" Southern Africa"> Southern Africa</a> </p> <a href="https://publications.waset.org/abstracts/61442/bipolar-reduction-and-lithic-miniaturization-experimental-results-and-archaeological-implications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61442.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">719</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> Analysis of Secondary School Students' Perceptions about Information Technologies through a Word Association Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fetah%20Eren">Fetah Eren</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Sahin"> Ismail Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Celik"> Ismail Celik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Oguz%20Akturk"> Ahmet Oguz Akturk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to discover secondary school students’ perceptions related to information technologies and the connections between concepts in their cognitive structures. A word association test consisting of six concepts related to information technologies is used to collect data from 244 secondary school students. Concept maps that present students’ cognitive structures are drawn with the help of frequency data. Data are analyzed and interpreted according to the connections obtained as a result of the concept maps. It is determined students associate most with these concepts—computer, Internet, and communication of the given concepts, and associate least with these concepts—computer-assisted education and information technologies. These results show the concepts, Internet, communication, and computer, are an important part of students’ cognitive structures. In addition, students mostly answer computer, phone, game, Internet and Facebook as the key concepts. These answers show students regard information technologies as a means for entertainment and free time activity, not as a means for education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=word%20association%20test" title="word association test">word association test</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20structure" title=" cognitive structure"> cognitive structure</a>, <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=secondary%20school" title=" secondary school"> secondary school</a> </p> <a href="https://publications.waset.org/abstracts/11758/analysis-of-secondary-school-students-perceptions-about-information-technologies-through-a-word-association-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11758.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">413</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> Human Factors Simulation Approach to Analyze Older Drivers’ Performance in Intersections Left-Turn Scenarios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yassir%20AbdelRazig">Yassir AbdelRazig</a>, <a href="https://publications.waset.org/abstracts/search?q=Eren%20Ozguven"> Eren Ozguven</a>, <a href="https://publications.waset.org/abstracts/search?q=Ren%20Moses"> Ren Moses</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While there exists a greater understanding of the differences between the driving behaviors of older and younger drivers, there is still a need to further understand how the two groups perform when attempting to perform complex intersection maneuvers. This paper looks to determine if, and to what extent, these differences exist when drivers encounter permissive left-hand turns, pedestrian traffic, two and four-lane intersections, heavy fog, and night conditions. The study will utilize a driving simulator to develop custom drivable scenarios containing one or more of the previously mentioned conditions. 32 younger and 32 older (+65 years) participants perform driving simulation scenarios and have their velocity, time to the nearest oncoming vehicle, accepted and rejected gaps, etc., recorded. The data collected from the simulator is analyzed via Raff’s method and logistic regression in order to determine and compare the critical gaps values of the two cohorts. Out of the parameters considered for this study, only the age of the driver, their experience (if they are a younger driver), the size of a gap, and the presence of pedestrians on the crosswalk proved significant. The results did not support the hypothesis that older drivers would be significantly more conservative in their critical gaps judgment and acceptance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=older%20drivers" title="older drivers">older drivers</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=left-turn" title=" left-turn"> left-turn</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20factors" title=" human factors"> human factors</a> </p> <a href="https://publications.waset.org/abstracts/67405/human-factors-simulation-approach-to-analyze-older-drivers-performance-in-intersections-left-turn-scenarios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67405.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">248</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> Resilience Assessment for Power Distribution Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Berna%20Eren%20Tokgoz">Berna Eren Tokgoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Safa"> Mahdi Safa</a>, <a href="https://publications.waset.org/abstracts/search?q=Seokyon%20Hwang"> Seokyon Hwang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Power distribution systems are essential and crucial infrastructures for the development and maintenance of a sustainable society. These systems are extremely vulnerable to various types of natural and man-made disasters. The assessment of resilience focuses on preparedness and mitigation actions under pre-disaster conditions. It also concentrates on response and recovery actions under post-disaster situations. The aim of this study is to present a methodology to assess the resilience of electric power distribution poles against wind-related events. The proposed methodology can improve the accuracy and rapidity of the evaluation of the conditions and the assessment of the resilience of poles. The methodology provides a metric for the evaluation of the resilience of poles under pre-disaster and post-disaster conditions. The metric was developed using mathematical expressions for physical forces that involve various variables, such as physical dimensions of the pole, the inclination of the pole, and wind speed. A three-dimensional imaging technology (photogrammetry) was used to determine the inclination of poles. Based on expert opinion, the proposed metric was used to define zones to visualize resilience. Visual representation of resilience is helpful for decision makers to prioritize their resources before and after experiencing a wind-related disaster. Multiple electric poles in the City of Beaumont, TX were used in a case study to evaluate the proposed methodology.   <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photogrammetry" title="photogrammetry">photogrammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20distribution%20systems" title=" power distribution systems"> power distribution systems</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience%20metric" title=" resilience metric"> resilience metric</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20resilience" title=" system resilience"> system resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=wind-related%20disasters" title=" wind-related disasters"> wind-related disasters</a> </p> <a href="https://publications.waset.org/abstracts/72984/resilience-assessment-for-power-distribution-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72984.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">221</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> Biodegradation of Phenazine-1-Carboxylic Acid by Rhodanobacter sp.

Phenazine-1-carboxylic acid (PCA) as one of 'core' phenazines are converted from chorismic acid before modified to other phenazine derivatives in different cells. Phenazines have attracted enormous interests because of their multiple roles on biocontrol, bacterial interaction, biofilm formation and fitness of their producers. However, in spite of ecological importance, degradation as a part of phenazines’ fate only have extremely limited attention now. Here, to isolate PCA-degrading bacteria, 200 mg L-1 PCA was supplied as sole carbon, nitrogen and energy source in minimal mineral medium. Quantitative PCR and Reverse-transcript PCR were employed to study abundance and activity of functional gene MFORT 16269 in PCA degradation, respectively. Intermediates and products of PCA degradation were identified with LC-MS/MS. After enrichment and isolation, a PCA-degrading strain was selected from soil and was designated as Rhodanobacter sp. PCA2 based on full 16S rRNA sequencing. As determined by HPLC, strain PCA2 consumed 200 mg L-1 (836 µM) PCA at a rate of 17.4 µM h-1, accompanying with significant cells yield from 1.92 × 105 to 3.11 × 106 cells per mL. Strain PCA2 was capable of degrading other phenazines as well, including phenazine (4.27 µM h-1), pyocyanin (2.72 µM h-1), neutral red (1.30 µM h-1) and 1-hydroxyphenazine (0.55 µM h-1). Moreover, during the incubation, transcript copies of MFORT 16269 gene increased significantly from 2.13 × 106 to 8.82 × 107 copies mL-1, which was 2.77 times faster than that of the corresponding gene copy number (2.20 × 106 to 3.32 × 107 copies mL-1), indicating that MFORT 16269 gene was activated and played roles on PCA degradation. As analyzed by LC-MS/MS, decarboxylation from the ring structure was determined as the first step of PCA degradation, followed by cleavage of nitrogen-containing ring by dioxygenase which catalyzed phenazine to nitrosobenzene. Subsequently, phenylhydroxylamine was detected after incubation for two days and was then transferred to aniline and catechol. Additionally, genomic and proteomic analyses were also carried out for strain PCA2. Overall, the findings presented here showed that a newly isolated strain Rhodanobacter sp. PCA2 was capable of degrading phenazines through decarboxylation and cleavage of nitrogen-containing ring, during which MFORT 16269 gene was activated and played important roles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decarboxylation" title="decarboxylation">decarboxylation</a>, <a href="https://publications.waset.org/abstracts/search?q=MFORT16269%20gene" title=" MFORT16269 gene"> MFORT16269 gene</a>, <a href="https://publications.waset.org/abstracts/search?q=phenazine-1-carboxylic%20acid%20degradation" title=" phenazine-1-carboxylic acid degradation"> phenazine-1-carboxylic acid degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhodanobacter%20sp.%20PCA2" title=" Rhodanobacter sp.

Taking into account limited resources (i.e. beds), the related service managers are obliged to manage their resources effectively due to the non-elective admissions which are mostly admitted to inpatient specialities via A&E departments. Geriatric medicine is one of specialities that have long length of stay for the non-elective admissions. This study aims to develop a discrete event simulation model to understand how possible increases on non-elective demand over the next 12 months affect the bed occupancy rate and to determine required number of beds in a geriatric medicine speciality in a UK hospital. In our validated simulation model, we take into account observed frequency distributions which are derived from a big data covering the period April, 2009 to January, 2013, for the non-elective admission and the length of stay. An experimental analysis, which consists of 16 experiments, is carried out to better understand possible effects of case studies and scenarios related to increase on demand and number of bed. As a result, the speciality does not achieve the target level in the base model although the bed occupancy rate decreases from 125.94% to 96.41% by increasing the number of beds by 30%. In addition, the number of required beds is more than the number of beds considered in the scenario analysis in order to meet the bed requirement.

Particularly, these models are based on the Dirichlet Process Mixture of Generalized Linear regression (DML) and change-point regression (CR). The model frameworks were implemented using 2015 historical traffic data aggregated at a 15-minute interval from an Interstate 295 freeway in Jacksonville, Florida. Using the deviance information criterion (DIC) to identify the appropriate number of mixture components, three traffic states were identified as free-flow, transitional, and congested condition. Results of the DML revealed that traffic occupancy is statistically significant in influencing the reduction of traffic speed in each of the identified states. Influence on the free-flow and the congested state was estimated to be higher than the transitional flow condition in both evening and morning peak periods. Estimation of the critical speed threshold using CR revealed that 47 mph and 48 mph are speed thresholds for congested and transitional traffic condition during the morning peak hours and evening peak hours, respectively. Free-flow speed thresholds for morning and evening peak hours were estimated at 64 mph and 66 mph, respectively. The proposed approaches will facilitate accurate detection and prediction of traffic congestion for developing effective countermeasures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traffic%20congestion" title="traffic congestion">traffic congestion</a>, <a href="https://publications.waset.org/abstracts/search?q=multistate%20speed%20distribution" title=" multistate speed distribution"> multistate speed distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20occupancy" title=" traffic occupancy"> traffic occupancy</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirichlet%20process%20mixtures%20of%20generalized%20linear%20model" title=" Dirichlet process mixtures of generalized linear model"> Dirichlet process mixtures of generalized linear model</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20change-point%20detection" title=" Bayesian change-point detection"> Bayesian change-point detection</a> </p> <a href="https://publications.waset.org/abstracts/67198/evaluating-traffic-congestion-using-the-bayesian-dirichlet-process-mixture-of-generalized-linear-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67198.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">294</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> Effects of the Supplementation of Potassium Humate at Different Levels to the Dairy Cows' Concentrated Mix during Dry Period on Early Lactation Yield Parameters and Dam/Calf Immunity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cangir%20Uyarlar">Cangir Uyarlar</a>, <a href="https://publications.waset.org/abstracts/search?q=E.%20Eren%20Gultepe"> E.

For this purpose, 50 Holstein dairy cows divided 5 trial groups. Experimental groups were designed as follows: A) Control (0% Humas); B) 0.5 Humas (0,5% in concentrated diet); C) 1 Humas (1% in concentrated diet), D) 1,5 Humas (1,5% in concentrated diet), E) 2 Humas (2% in concentrated diet), respectively. The study lasted from the first day of the dry period to postpartum 30th day. Diets were prepared as isocaloric and isonitrogenic. In the experiment, the day on which the animals gave birth was accepted as ‘0 (zero)’ and blood was taken from tail vein (v. coccygea) at -60, -53, -46, -39, -32, -25, -18, -11, -4, 0, ; Colostrum samples were taken on days 0, 1 and 2; Blood samples were taken on days 0, 1, 2, 15 and 30 from the juguler vein (v. jugularis) of the new born calves.

The results suggest that although the supplementation of humic acid at 2% level adversely affected to production parameters, the addition of humic acid (potassium humate) to the concentrate mix during the dry period (particularly 0.5 and 1% levels) may provide an increasing on mother and the offspring immunity, some improving on serum metabolism parameters and enhancing the milk production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=humic%20acid" title="humic acid">humic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20cow" title=" dairy cow"> dairy cow</a>, <a href="https://publications.waset.org/abstracts/search?q=calf" title=" calf"> calf</a>, <a href="https://publications.waset.org/abstracts/search?q=immunity" title=" immunity"> immunity</a> </p> <a href="https://publications.waset.org/abstracts/79053/effects-of-the-supplementation-of-potassium-humate-at-different-levels-to-the-dairy-cows-concentrated-mix-during-dry-period-on-early-lactation-yield-parameters-and-damcalf-immunity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79053.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">207</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Influence of Travel Time Reliability on Elderly Drivers Crash Severity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ren%20Moses">Ren Moses</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kidando"> Emmanuel Kidando</a>, <a href="https://publications.waset.org/abstracts/search?q=Eren%20Ozguven"> Eren Ozguven</a>, <a href="https://publications.waset.org/abstracts/search?q=Yassir%20Abdelrazig"> Yassir Abdelrazig</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although older drivers (defined as those of age 65 and above) are less involved with speeding, alcohol use as well as night driving, they are more vulnerable to severe crashes. The major contributing factors for severe crashes include frailty and medical complications. Several studies have evaluated the contributing factors on severity of crashes. However, few studies have established the impact of travel time reliability (TTR) on road safety. In particular, the impact of TTR on senior adults who face several challenges including hearing difficulties, decreasing of the processing skills and cognitive problems in driving is not well established. Therefore, this study focuses on determining possible impacts of TTR on the traffic safety with focus on elderly drivers. Historical travel speed data from freeway links in the study area were used to calculate travel time and the associated TTR metrics that is, planning time index, the buffer index, the standard deviation of the travel time and the probability of congestion. Four-year information on crashes occurring on these freeway links was acquired. The binary logit model estimated using the Markov Chain Monte Carlo (MCMC) sampling technique was used to evaluate variables that could be influencing elderly crash severity. Preliminary results of the analysis suggest that TTR is statistically significant in affecting the severity of a crash involving an elderly driver. The result suggests that one unit increase in the probability of congestion reduces the likelihood of the elderly severe crash by nearly 22%. These findings will enhance the understanding of TTR and its impact on the elderly crash severity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=highway%20safety" title="highway safety">highway safety</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20time%20reliability" title=" travel time reliability"> travel time reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=elderly%20drivers" title=" elderly drivers"> elderly drivers</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20modeling" title=" traffic modeling"> traffic modeling</a> </p> <a href="https://publications.waset.org/abstracts/57953/influence-of-travel-time-reliability-on-elderly-drivers-crash-severity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">493</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Changing Roles and Skills of Urban Planners in the Turkish Planning System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Eren">Fatih Eren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to find an answer to the question of which knowledge and skills do the Turkish urban planners need in their business practice. Understanding change in cities, making a prediction, making an urban decision and putting it into practice, working together with actors from different organizations from various academic disciplines, persuading people to accept something and developing good personal and professional relationships have become very complex and difficult in today’s world. The truth is that urban planners work in many institutions under various positions which are not similar to each other by field of activity and all planners are forced to develop some knowledge and skills for success in their business in Turkey. This study targets to explore what urban planners do in the global information age. The study is the product of a comprehensive nation-wide research. In-depth interviews were conducted with 174 experienced urban planners, who work in different public institutions and private companies under varied positions in the Turkish Planning System, to find out knowledge and skills needed by next-generation urban planners. The main characteristics of next-generation urban planners are defined; skills that planners needed today are explored in this paper. Findings show that the positivist (traditional) planning approach has given place to anti-positivist planning approaches in the Turkish Planning System so next-generation urban planners who seek success and want to carve out a niche for themselves in business life have to equip themselves with innovative skills. The result section also includes useful and instructive findings for planners about what is the meaning of being an urban planner and what is the ideal content and context of planning education at universities in the global age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=global%20information%20age" title="global information age">global information age</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20Planning%20System" title=" Turkish Planning System"> Turkish Planning System</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20institutional%20approach" title=" the institutional approach"> the institutional approach</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20planners" title=" urban planners"> urban planners</a>, <a href="https://publications.waset.org/abstracts/search?q=roles" title=" roles"> roles</a>, <a href="https://publications.waset.org/abstracts/search?q=skills" title=" skills"> skills</a>, <a href="https://publications.waset.org/abstracts/search?q=values" title=" values"> values</a> </p> <a href="https://publications.waset.org/abstracts/47748/changing-roles-and-skills-of-urban-planners-in-the-turkish-planning-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47748.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">285</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> Complex Network Approach to International Trade of Fossil Fuel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Semanur%20Soyyigit%20Kaya">Semanur Soyyigit Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ercan%20Eren"> Ercan Eren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy has a prominent role for development of nations. Countries which have energy resources also have strategic power in the international trade of energy since it is essential for all stages of production in the economy. Thus, it is important for countries to analyze the weakness and strength of the system. On the other side, it is commonly believed that international trade has complex network properties. Complex network is a tool for the analysis of complex systems with heterogeneous agents and interaction between them. A complex network consists of nodes and the interactions between these nodes. Total properties which emerge as a result of these interactions are distinct from the sum of small parts (more or less) in complex systems. Thus, standard approaches to international trade are superficial to analyze these systems. Network analysis provides a new approach to analyze international trade as a network. In this network countries constitute nodes and trade relations (export or import) constitute edges. It becomes possible to analyze international trade network in terms of high degree indicators which are specific to complex systems such as connectivity, clustering, assortativity/disassortativity, centrality, etc. In this analysis, international trade of crude oil and coal which are types of fossil fuel has been analyzed from 2005 to 2014 via network analysis. First, it has been analyzed in terms of some topological parameters such as density, transitivity, clustering etc. Afterwards, fitness to Pareto distribution has been analyzed. Finally, weighted HITS algorithm has been applied to the data as a centrality measure to determine the real prominence of countries in these trade networks. Weighted HITS algorithm is a strong tool to analyze the network by ranking countries with regards to prominence of their trade partners. We have calculated both an export centrality and an import centrality by applying w-HITS algorithm to data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20network%20approach" title="complex network approach">complex network approach</a>, <a href="https://publications.waset.org/abstracts/search?q=fossil%20fuel" title=" fossil fuel"> fossil fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20trade" title=" international trade"> international trade</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20theory" title=" network theory"> network theory</a> </p> <a href="https://publications.waset.org/abstracts/42251/complex-network-approach-to-international-trade-of-fossil-fuel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42251.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Effect of Different Level of Pomegranate Molasses on Performance, Egg Quality Trait, Serological and Hematological Parameters in Older Laying Hens </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Bayram">Ismail Bayram</a>, <a href="https://publications.waset.org/abstracts/search?q=Aamir%20Iqbal"> Aamir Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=E.%20Eren%20Gultepe"> E.

A total of 240 Babcock white laying hens (52 weeks old) were divided into 5 groups (n=48) with 8 subgroups having 6 hens in each. Pomegranate molasses was added in the drinking water to experimental groups with 0 %, 0.1%, 0.25 %, 0.5%, and 1%, respectively during one month. In our results, egg weight values were remained the same in all pomegranate molasses supplemented groups except 1% group over control. However, feed consumption, egg production, feed conversion ratio (FCR), egg mass, egg yolk cholesterol, body weights, and water consumption remained unaffected (P > 0.05). During mid-study (15 Days) analyses, egg quality parameters such as Haugh unit, eggshell thickness, albumin index, yolk index, and egg yolk color were remained non-significant (P > 0.05) while after final (30 Days) egg analyses, only egg yolk color had positively (P < 0.05) increased in 0.5% group. Moreover, Haugh unit, eggshell thickness, and albumin index were not significantly (P > 0.05) affected by the supplementation of pomegranate molasses. Regarding serological parameters, pomegranate molasses did not show any positive effect on cholesterol, total protein, LDL, HDL, GGT, AST, ALT, and glucose level. Similarly, pomegranate molasses also showed non-significant (P > 0.05) results on different blood parameters such as HCT, RBC, MCV, MCH, MCHC, PLT, RDWC, MPV except hemoglobin level. Only hemoglobin level was increased in all experimental groups over control showing that pomegranate molasses can be used as an enhancer in animals with low hemoglobin level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pomegranate%20molasses" title="pomegranate molasses">pomegranate molasses</a>, <a href="https://publications.waset.org/abstracts/search?q=laying%20hen" title=" laying hen"> laying hen</a>, <a href="https://publications.waset.org/abstracts/search?q=egg%20yield" title=" egg yield"> egg yield</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20parameters" title=" blood parameters"> blood parameters</a> </p> <a href="https://publications.waset.org/abstracts/107654/effect-of-different-level-of-pomegranate-molasses-on-performance-egg-quality-trait-serological-and-hematological-parameters-in-older-laying-hens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107654.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">9</span> Expression of Micro RNAs in the Liver Tissue of Mice Generated through in vitro Embryo Culture and Embryo Transfer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6ksel%20Do%C4%9Fan">Göksel Doğan</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20%C3%96zt%C3%BCrk"> Murat Öztürk</a>, <a href="https://publications.waset.org/abstracts/search?q=Didar%20Tu%C4%9F%C3%A7e%20Karakulak"> Didar Tuğçe Karakulak</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Nurullah%20Orman"> Mehmet Nurullah Orman</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Sylvius"> Nicolas Sylvius</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Blades"> Matthew Blades</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Sand%C4%B1k%C3%A7%C4%B1"> Mustafa Sandıkçı</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengiz%20%C3%9Cnsal"> Cengiz Ünsal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehtap%20K%C4%B1l%C4%B1%C3%A7%20Eren"> Mehtap Kılıç Eren</a>, <a href="https://publications.waset.org/abstracts/search?q=Funda%20K%C4%B1ral"> Funda Kıral</a>, <a href="https://publications.waset.org/abstracts/search?q=Levent%20Karagen%C3%A7"> Levent Karagenç</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assisted reproduction is associated with impaired glucose metabolism in adulthood. miRNAs are key regulators of glucose metabolism. Whether embryo culture and/or transfer alters the expression of miRNAs and to what extent this process affects glucose metabolism remain largely unknown. The purpose of the present study was to examine the expression of miRNAs in the liver in mice obtained by the transfer of blastocysts. The study was comprised of an experimental (EG) and a control group (CG). EG was generated by embryo transfer to pseudo-pregnant females. Mice born from naturally ovulating females were used as the CG. Differential expression of miRNAs, blood glucose, plasma insulin, liver glycogen, and activities of some of the rate-limiting enzymes involved in glucose metabolism were determined at ten weeks of age. Blood glucose, plasma insulin, and glycogen concentrations were similar between the groups in both sexes. Activities of enzymes were similar among females. EG males had significantly less glucokinase and phosphofructokinase activity compared to CG males. None of the miRNAs were differentially expressed in males. On the other hand, miR-143-3p expression was upregulated in EG females. Expression of none of the genes targeted by miR143-3p differed between the groups. These results demonstrate that miR143-3p, a novel regulator of type 2 diabetes, is upregulated in mice generated by assisted reproduction in a sexually-dimorphic manner with no apparent effect on glucose and insulin levels at ten weeks of age. It remains to be determined if this process is associated with impaired glucose homeostasis in the long term. <p class="card-text"><strong>Keywords:</strong> <a
