Hydrophobic and hydrophilic characteristics Two types of nano CaCO3 were replaced with Portland cement at 0, 0.5 and 1%. Water to (cement+nano-CaCO3) ratio was kept constant at 0.5 for all mixtures. 36 indentations were applied on each cement paste, and the values of nano-hardness and elastic modulus of cement pastes were determined from the indentation depth-load graphs. Then, by getting the average of them, nano-hardness and elastic modulus were identified for each mixture. Test results illustrate that replacement of hydrophilic n-CaCO3 with cement lead to a significant increase in nano-mechanical properties, however, replacement of hydrophobic n-CaCO3 with cement worsened the nano-mechanical properties considerably. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoindenter" title="nanoindenter">nanoindenter</a>, <a href="https://publications.waset.org/abstracts/search?q=CaCO3" title=" CaCO3"> CaCO3</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-hardness" title=" nano-hardness"> nano-hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-mechanical%20properties" title=" nano-mechanical properties"> nano-mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/54618/effect-of-nano-caco3-addition-on-the-nano-mechanical-properties-of-cement-paste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54618.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">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Effect of Fiber Types and Elevated Temperatures on the Bond Characteristic of Fiber Reinforced Concretes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erdo%C4%9Fan%20%C3%96zbay">Erdoğan Özbay</a>, <a href="https://publications.waset.org/abstracts/search?q=Hakan%20T.%20T%C3%BCrker"> Hakan T.

In addition, a plain concrete (without fiber) was produced and used as a control. Test results obtained showed that the steel fiber reinforced concrete (SFRC) had the highest compressive strength, modulus of rapture and bond stress values at room temperatures, the residual bond, flexural and compressive strengths of both FRC and plain concrete dropped sharply after exposure to high temperatures. The results also indicated that the reduction of bond, flexural and compressive strengths with increasing the exposed temperature was relatively less for SFRC than for plain, and FRC with PPF and PVA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bond%20stress" title="bond stress">bond stress</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=elevated%20temperatures" title=" elevated temperatures"> elevated temperatures</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20reinforced%20concrete" title=" fiber reinforced concrete"> fiber reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rapture" title=" modulus of rapture"> modulus of rapture</a> </p> <a href="https://publications.waset.org/abstracts/29676/effect-of-fiber-types-and-elevated-temperatures-on-the-bond-characteristic-of-fiber-reinforced-concretes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29676.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">421</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Hyper Presidentialism and First Year of the Turkish Type of Presidentialism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Ekinci">Ahmet Ekinci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The new government system of Turkey can be described as hyper-presidentialism, this is because the president then becomes the arbiter of all powers. In another word, the power to enact decrees, appoint bureaucrats and judicial officials into offices, and the power to dissolve a parliament belongs solely to the president. As a strong presidency fuse with a disciplined party system as well as concurrent elections and 10 percent electoral threshold, the president possibly poses a great danger to the separation of powers. Additionally, with regards to the presidential term, the president constitutionally holds the power to be elected only for two terms in Turkey. However, Erdoğan and his supporters believe that the 2017 constitutional amendments that changed the system of government have reset the agenda. Thus, the 2017 amendments offered Erdoğan a secret opportunity to join the presidential election race for a third and even a fourth term. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hyper-presidentialism" title="hyper-presidentialism">hyper-presidentialism</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20presidentialism" title=" Turkish presidentialism"> Turkish presidentialism</a>, <a href="https://publications.waset.org/abstracts/search?q=presidential%20decree" title=" presidential decree"> presidential decree</a>, <a href="https://publications.waset.org/abstracts/search?q=concurrent%20election" title=" concurrent election"> concurrent election</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdogan%E2%80%99s%20term%20limit" title=" Erdogan’s term limit"> Erdogan’s term limit</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20government%20system" title=" Turkish government system"> Turkish government system</a> </p> <a href="https://publications.waset.org/abstracts/130869/hyper-presidentialism-and-first-year-of-the-turkish-type-of-presidentialism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130869.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Optimum Design of Alkali Activated Slag Concretes for Low Chloride Ion Permeability and Water Absorption Capacity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M%C3%BCzeyyen%20Bal%C3%A7ikanli">Müzeyyen Balçikanli</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdo%C4%9Fan%20%C3%96zbay"> Erdoğan Özbay</a>, <a href="https://publications.waset.org/abstracts/search?q=Hakan%20Tacettin%20T%C3%BCrker"> Hakan Tacettin Türker</a>, <a href="https://publications.waset.org/abstracts/search?q=Okan%20Karahan"> Okan Karahan</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengiz%20Duran%20Ati%C5%9F"> Cengiz Duran Atiş</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, effect of curing time (TC), curing temperature (CT), sodium concentration (SC) and silicate modules (SM) on the compressive strength, chloride ion permeability, and water absorption capacity of alkali activated slag (AAS) concretes were investigated.

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">311</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Role of Sodium Concentration, Waiting Time and Constituents’ Temperature on the Rheological Behavior of Alkali Activated Slag Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammet%20M.%20Erdem">Muhammet M.

For this purpose, an experimental program was conducted with four different SCs of 1.85, 3.0, 4.15, and 5.30%, three different WT of 0 (just after production), 15, and 30 minutes and three different CT of 18, 30, and 40 °C. Solid precursors are activated by water glass and sodium hydroxide solutions with silicate modulus (Ms = SiO<sub>2</sub>/Na<sub>2</sub>O) of 1. Slag content and (water + activator solution)/slag ratio were kept constant in all mixtures. Yield stress and plastic viscosity values were defined for each mixture by using the ICAR rheometer. Test results were demonstrated that all of the three studied parameters have tremendous effect on the yield stress and plastic viscosity values of the alkali activated slag concretes. Increasing the SC, WT, and CT drastically augmented the rheological parameters. At the 15 and 30 minutes WT after production, most of the alkali activated slag concretes were set instantaneously, and rheological measurements were not performed. <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=rheology" title=" rheology"> rheology</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20stress" title=" yield stress"> yield stress</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20viscosity" title=" plastic viscosity"> plastic viscosity</a> </p> <a href="https://publications.waset.org/abstracts/54616/role-of-sodium-concentration-waiting-time-and-constituents-temperature-on-the-rheological-behavior-of-alkali-activated-slag-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54616.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">289</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">45</span> Post-Islamism, Turkish Referendum and the Anatolian Middle Class</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Firmanda%20Taufiq">Firmanda Taufiq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Turkey as a country with great political power and political dynamics that occurred in Turkey shows symptoms that make this country interesting enough to be studied. In addition, there is also Post-Islamism phenomenon that causes fluctuations and changes in Turkish politics. In this regard, Turkey carved out history by holding a referendum that changed the state system from a parliamentary system with a presidential system. This change has major implications in the life of Turkish society and politics. The condition is not only influenced by the government of Recep Tayyib Erdogan alone, but actually there is also anxiety middle class Turkish (Middle Class Anatolia). So there was a Turkish referendum held on 16 April 2017. This research using descriptive-analysis method to analyzing problems of research, that's how the post-Islamism situation in Turkey and Anatolian Middle Class impact to Turkish referendum. Actually, the political process that took place in Turkey is inseparable from Post-Islamism which became an important part in the change and transition of government system. The AKP Party as the basis of the Erdogan government movement became an important actor in the political and policy dynamics produced by the Erdogan government. It is then why the Turkish referendum took place. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post-Islamism" title="post-Islamism">post-Islamism</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20politic" title=" Turkish politic"> Turkish politic</a>, <a href="https://publications.waset.org/abstracts/search?q=AKP" title=" AKP"> AKP</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20class%20Anatolia" title=" middle class Anatolia"> middle class Anatolia</a> </p> <a href="https://publications.waset.org/abstracts/79698/post-islamism-turkish-referendum-and-the-anatolian-middle-class" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79698.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">480</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">44</span> FengShui Paradigm as Philosophy of Sustainable Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Erdogan">E.

Erdogan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> FengShui, an old Chinese discipline, dates back to more than 5000 years, is one of the design principles that aim at creating habitable and sustainable spaces in harmony with nature by systematizing data within its own structure. Having emerged from Chinese mysticism and embodying elements of faith in its principles, FengShui argues that the positive energy in the environment channels human behavior and psychology. This argument is supported with the thesis of quantum physics that ‘everything is made up of energy’ and gains an important place. In spaces where living and working take place with several principles and systematized rules, FengShui promises a happier, more peaceful and comfortable life by influencing human psychology, acts, and soul as well as the professional and social life of the individual. Observing these design properties in houses, workplaces, offices, the environment, and daily life as a design paradigm is significant. In this study, how FengShui, a Central Asian culture emanated from Chinese mysticism, shapes design and how it is used as an element of sustainable design will be explained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Feng%20Shui" title="Feng Shui">Feng Shui</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20principle" title=" design principle"> design principle</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy" title=" philosophy"> philosophy</a> </p> <a href="https://publications.waset.org/abstracts/14058/fengshui-paradigm-as-philosophy-of-sustainable-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14058.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">542</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">43</span> The Effects of Lipid Emulsion, Magnesium Sulphate and Metoprolol in Amitryptiline-Induced Cardiovascular Toxicity in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saylav%20Ejder%20Bora">Saylav Ejder Bora</a>, <a href="https://publications.waset.org/abstracts/search?q=Arife%20Erdogan"> Arife Erdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mumin%20Alper%20Erdogan"> Mumin Alper Erdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Oytun%20Erbas"> Oytun Erbas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismet%20Parlak"> Ismet Parlak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The aim of this study was to evaluate histological, electrical and biochemical effects of metoprolol, lipid emulsion and magnesium sulphate as an alternative method to be used in preventing long QT emergence, that is among the lethal consequences of amitryptiline toxicity. Methods: Thirty Sprague- Dawley male rats were included. Rats were randomly separated into 5 groups. First group was administered saline only while the rest had received amitryptiline 100 mg/kg + saline, 5 mg/kg metoprolol, 20 ml/kg lipid emulsion and 75 mg/kg magnesium sulphate (MgSO4) intraperitoneally. ECG at DI lead, biochemical tests following euthanasia were performed in all groups after 1 hour of administration. Cardiac tissues were removed, sections were prepared and examined. Results: QTc values were significantly shorter in the rest when compared to amitryptiline+ saline group. While lipid emulsion did not affect proBNP and troponin values biochemically as compared to that of the control group, histologically, it was with reduced caspase 3 expression. Though statistically insignificant in the context of biochemical changes, pro-BNP and urea levels were lower in the metoprolol group when compared to controls. Similarly, metoprolol had no statistically significant effect on histological caspase 3 expression in the group that was treated with amitryptiline+metoprolol. On the other hand, there was a statistically significant decrease in Troponin, pro-BNP and urea levels as well as significant decline in histological caspase 3 expression within the MgSO4 group when compared to controls. Conclusion: As still a frequent cause of mortality in emergency units, administration of MgSO4, lipid emulsion and metoprolol might be beneficial in alternative treatment of cardiovascular toxicity caused by tricyclic antidepressant overdose, whether intake would be intentional or accidental. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amitryptiline" title="amitryptiline">amitryptiline</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20toxicity" title="cardiovascular toxicity">cardiovascular toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20QT" title=" long QT"> long QT</a>, <a href="https://publications.waset.org/abstracts/search?q=Rat%20Model" title=" Rat Model"> Rat Model</a> </p> <a href="https://publications.waset.org/abstracts/80037/the-effects-of-lipid-emulsion-magnesium-sulphate-and-metoprolol-in-amitryptiline-induced-cardiovascular-toxicity-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80037.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">176</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">42</span> Fracture and Fatigue Crack Growth Analysis and Modeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Volkmar%20Nolting">Volkmar Nolting</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fatigue crack growth prediction has become an important topic in both engineering and non-destructive evaluation.

Since the dawn of the Turkish Republic, at the end of the First World War, the new Turkish leadership was urged to deal with the religious heritage of the Sultanate. Mustafa Kemal Ataturk, Turkey’s first President, led the country in a process of internal change, substantially modifying not merely the democratic stance of it, but also the way politics was addressing the Muslim faith. Islam was banned from the public sector of the society and was drastically marginalized to the mere private sphere of citizens’ lives. Headscarves were banned from institutional buildings together with any other religious practice, while the country was proceeding down a path of secularism and Westernization. This issue is demonstrated by the fact that even a new elected Prime Minister, Recep Tayyip Erdoğan, was initially barred from taking the institutional position, because of allegations that he had read a religious text while campaigning. Over the years, thanks to this initial internal shift, Turkey has often been seen by Western partners as one of the few countries that had managed to find a perfect balance between a democratic stance and an Islamic inherent nature. In the early 2000s, this led many academics to believe that Ankara could eventually have become the next European capital. Since then, the internal and external landscape of Turkey has drastically changed. Today, religion has returned to be an important point of reference for Turkish politics, considering also the failure of the European negotiations and the always more unstable external environment of the country. This paper wants to address this issue, looking at the important role religion has covered in the Turkish society and the way it has been politicized since the early years of the Republic. It will evolve from a more theoretical debate on secularism and the path of political westernization of Turkey under Ataturk’s rule to a more practical analysis of today’s situation, passing through the failure of Ankara’s accession into the EU and the current tense political relation with its traditional NATO allies. The final objective of this research, therefore, is not to offer a meticulous opinion on Turkey’s current international stance. This issue will be left entirely to the personal consideration of the reader. Rather, it will supplement the existing literature with a comprehensive and more structured analysis on the role Islam has played on Turkish politics since the early 1920s up until the political domestic revolution of the early 2000s, after the first electoral win of the Justice and Development Party (AKP). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=democracy" title="democracy">democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=Islam" title=" Islam"> Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Kemal%20Atat%C3%BCrk" title=" Mustafa Kemal Atatürk"> Mustafa Kemal Atatürk</a>, <a href="https://publications.waset.org/abstracts/search?q=Recep%20Tayyip%20Erdo%C4%9Fan" title=" Recep Tayyip Erdoğan"> Recep Tayyip Erdoğan</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/95443/turkey-at-the-end-of-the-second-decade-of-the-21st-century-a-secular-or-religious-country" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95443.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">208</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Effect of Different Microbial Strains on Biological Pretreatment of Sugarcane Bagasse for Enzymatic Hydrolysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Achiraya%20Jiraprasertwong">Achiraya Jiraprasertwong</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdogan%20Gulari"> Erdogan Gulari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumaeth%20Chavadej"> Sumaeth Chavadej</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Among agricultural residues, sugarcane bagasse is one of the most convincing raw materials for the production of bioethanol due to its availability, and low cost through enzymatic hydrolysis and yeast fermentation.

According to all age groups and the oral care in various specific situations located evidence in the literature were examined. It has been determined that the methods and frequency used in oral care practices performed by nurses in clinics differ from one hospital to another. In addition, it is seen that different solutions are used in basic oral care, oral care practices to prevent ventilator-associated pneumonia and evidence-based practice in mucositis management in children.

Two toll plazas in New Jersey are selected as case studies and were developed and validated in Paramics traffic simulation software. In order to simulate drivers’ lane selection behavior in Paramics, a utility-based lane selection approach is implemented in Paramics Application Programming Interface (API). For each vehicle approaching the toll plaza, a utility value is assigned to each toll lane by taking into account the factors that are likely to impact drivers’ lane selection behavior, such as approach lane, exit lane and queue lengths. The results demonstrate that similar operational conditions, such as lane-by-lane toll plaza traffic volume can be attained using this approach. In addition, assessment of safety at toll plazas is conducted via a surrogate safety measure. In particular, the crash index (CI), an improved surrogate measure of time-to-collision (TTC), which reflects the severity of a crash is used in the simulation analyses. The results indicate that the spatial and temporal frequency of observed crashes can be simulated using the proposed methodology. Further analyses can be conducted to evaluate and compare various different operational decisions and safety measures using microscopic simulation models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microscopic%20simulation" title="microscopic simulation">microscopic simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=toll%20plaza" title=" toll plaza"> toll plaza</a>, <a href="https://publications.waset.org/abstracts/search?q=surrogate%20safety" title=" surrogate safety"> surrogate safety</a>, <a href="https://publications.waset.org/abstracts/search?q=application%20programming%20interface" title=" application programming interface"> application programming interface</a> </p> <a href="https://publications.waset.org/abstracts/95990/microscopic-simulation-of-toll-plaza-safety-and-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95990.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">183</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Pre-Beneficiation of Low Grade Diasporic Bauxite Ore by Reduction Roasting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koksal%20Y%C4%B1lmaz">Koksal Yılmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Birol"> Burak Birol</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhlis%20Nezihi%20Saridede"> Muhlis Nezihi Saridede</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdogan%20Yigit"> Erdogan Yigit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A bauxite ore can be utilized in Bayer Process, if the mass ratio of Al2O3 to SiO2 is greater than 10.

During the phase change, it is necessary to supply the latent heat of LPG to prevent excessive low temperature. Engine coolant is circulated in the pressure regulator for this purpose. Therefore, pressure regulator is a type of heat exchanger that should be designed for different engine operating conditions. The design of the regulator should ensure that the flow of LPG is in gaseous phase to the injectors during the engine steady state and transient operating conditions. The pressure regulators in the LPG gaseous injection systems currently used can easily change the phase of LPG, however, there is no any control on the LPG temperature in conventional LPG injection systems. It is possible to increase temperature excessively. In this study, a control unit has been tested to keep the LPG temperature in a band. Result of the study showed that the engine performance characteristics can be increased by using the system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=temperature" title="temperature">temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20regulator" title=" pressure regulator"> pressure regulator</a>, <a href="https://publications.waset.org/abstracts/search?q=LPG" title=" LPG"> LPG</a>, <a href="https://publications.waset.org/abstracts/search?q=PID" title=" PID"> PID</a> </p> <a href="https://publications.waset.org/abstracts/21944/pressure-regulator-optimization-in-lpg-fuel-injection-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21944.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">516</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">33</span> An Investigation of How Pre-Service Physics Teachers Perceived the Results of Buoyancy Force</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ersin%20Bozkurt">Ersin Bozkurt</a>, <a href="https://publications.waset.org/abstracts/search?q=%C5%9E%C3%BCkran%20Erdo%C4%9Fan"> Şükran Erdoğan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the study is to explore how pre-service teachers perceive buoyancy force effecting an object in a liquid and identify their misconceptions.

However, from the beginning of 20th century, these bridges have remained inadequate as a result of increasing speed, size and capacity of the means of transport. Although new bridges have been built in many places, masonry bridges located within the city limits still need to be used. When the size and transportation loads of modern vehicles are taken into account, it is apparent that historical masonry arch bridges would be exposed to greater loads than their initial design loads. Because of that, many precautions taken either remain insufficient or damage these bridges. In this study, the history of Debbaglar Bridge, one of the historic bridges located in the city center of Aksaray/Turkey is presented and its existing condition is evaluated. Structural analysis of the bridge under present conditions and loads is explained.

It is seen that since the 1990's, a wide variety of competitive marketing ideas have been offered systematically to target audiences in the field of politics as in other fields. When the components of marketing are taken into consideration, all kinds of communication efforts involving “political leaders”, who are conceptualized as products in terms of political marketing, serve a process of social persuasion, which cannot be restricted to election periods only, and a manageable “image”. In this context, image, which is concerned with how the political product is perceived, involves not only the political discourses shared with the public but also all kinds of biographical information about the leader, the leader’s specific way of living and routines and his/her attitudes and behaviors in their private lives, and all these are regarded as components of the “product image”. While on the one hand the leader’s verbal or supra-verbal references serve the way the “spirit of the product” is perceived –just as in brand positioning- they also show their self-esteem levels, in other words how they perceive themselves on the other hand. Indeed, their self-esteem levels are evaluated in three fundamental categories in the “Functional Analysis”, namely parent, child and adult, and it is revealed that the words, tone of voice and body language a person uses makes it easy to understand at what self-esteem level that person is. In this context, words, tone of voice and body language, which provide important clues as to the “self” of the person, are also an indication of how political leaders evaluate both “themselves” and “the mass/audience” in the communication they establish with their audiences. When the matter is taken from the perspective of Turkey, the levels of self-esteem in the relationships that the political leaders establish with the masses are also important in revealing how our society is seen from the perspective of a specific leader. Since the leader is a part of the marketing strategy of a political party as a product, this evaluation is significant in terms of the forms of relationships between political institutions in our country with the society. In this study, the self-esteem level in the documentary entitled “Master’s Story”, where Recep Tayyip Erdoğan’s life history is told, is analyzed in the context of words, tone of voice and body language. Within the scope of the study, at what level of self-esteem Recep Tayyip Erdoğan was in the “Master’s Story”, a documentary broadcast on Beyaz TV, was investigated using the content analysis method. First, based on the Functional Analysis Literature, a transactional approach scale was created regarding parent, adult and child self-esteem levels. On the basis of this scale, the prime minister’s self-esteem level was determined in three basic groups, namely “tone of voice”, “the words he used” and “body language”. Descriptive analyses were made to the data within the framework of these criteria and at what self-esteem level the prime minister spoke throughout the documentary was revealed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=political%20marketing" title="political marketing">political marketing</a>, <a href="https://publications.waset.org/abstracts/search?q=leader%20image" title=" leader image"> leader image</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20self-esteem" title=" level of self-esteem"> level of self-esteem</a>, <a href="https://publications.waset.org/abstracts/search?q=transactional%20approach" title=" transactional approach "> transactional approach </a> </p> <a href="https://publications.waset.org/abstracts/16575/a-functional-analysis-of-a-political-leader-in-terms-of-marketing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16575.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">338</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> Study on Microbial Pretreatment for Enhancing Enzymatic Hydrolysis of Corncob</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kessara%20Seneesrisakul">Kessara Seneesrisakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdogan%20Gulari"> Erdogan Gulari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumaeth%20Chavadej"> Sumaeth Chavadej</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The complex structure of lignocellulose leads to great difficulties in converting it to fermentable sugars for the ethanol production. The major hydrolysis impediments are the crystallinity of cellulose and the lignin content. To improve the efficiency of enzymatic hydrolysis, microbial pretreatment of corncob was investigated using two bacterial strains of Bacillus subtilis A 002 and Cellulomonas sp. TISTR 784 (expected to break open the crystalline part of cellulose) and lignin-degrading fungus, Phanerochaete sordida SK7 (expected to remove lignin from lignocellulose). The microbial pretreatment was carried out with each strain under its optimum conditions. The pretreated corncob samples were further hydrolyzed to produce reducing glucose with low amounts of commercial cellulase (25 U•g-1 corncob) from Aspergillus niger. The corncob samples were determined for composition change by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscope (SEM). According to the results, the microbial pretreatment with fungus, P. sordida SK7 was the most effective for enhancing enzymatic hydrolysis, approximately, 40% improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corncob" title="corncob">corncob</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymatic%20hydrolysis" title=" enzymatic hydrolysis"> enzymatic hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=glucose" title=" glucose"> glucose</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20pretreatment" title=" microbial pretreatment"> microbial pretreatment</a> </p> <a href="https://publications.waset.org/abstracts/12998/study-on-microbial-pretreatment-for-enhancing-enzymatic-hydrolysis-of-corncob" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12998.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">585</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">29</span> Evaluation of Satellite and Radar Rainfall Product over Seyhan Plain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaz%C4%B1m%20Kaba">Kazım Kaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdem%20Erdi"> Erdem Erdi</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Akif%20Erdo%C4%9Fan"> M.

Therefore rain rate should be known well both spatial and temporal for any area. Rainfall is measured by using rain-gauge at meteorological ground stations traditionally for many years. At the present time, rainfall products are acquired from radar and satellite images with a temporal and spatial continuity. In this study, we investigated the accuracy of these rainfall data according to rain-gauge data. For this purpose, we used Adana-Hatay radar hourly total precipitation product (RN1) and Meteosat convective rainfall rate (CRR) product over Seyhan plain. We calculated daily rainfall values from RN1 and CRR hourly precipitation products. We used the data of rainy days of four stations located within range of the radar from October 2013 to November 2015. In the study, we examined two rainfall data over Seyhan plain and the correlation between the rain-gauge data and two raster rainfall data was observed lowly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=meteosat" title="meteosat">meteosat</a>, <a href="https://publications.waset.org/abstracts/search?q=radar" title=" radar"> radar</a>, <a href="https://publications.waset.org/abstracts/search?q=rainfall" title=" rainfall"> rainfall</a>, <a href="https://publications.waset.org/abstracts/search?q=rain-gauge" title=" rain-gauge"> rain-gauge</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/61709/evaluation-of-satellite-and-radar-rainfall-product-over-seyhan-plain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61709.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">328</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> An Alternative and Complementary Medicine Method in Vulnerable Pediatric Cancer Patients: Yoga</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%87.%20Erdo%C4%9Fan">Ç.

Members of the subfamily live as parasitoids on the families Curculionidae and Apionidae (Coleoptera), which also include very important agricultural pests.  In generally, members of the genus Triaspis are poorly known biologically. The genus is represented by 37 species in the West Palearctic region and 118 species worldwide. Adult specimens of Triaspis were collected from as wide a range of habitats as possible at different altitudes in different parts of Turkey between 1982 and 2010. Samples collected from short plants using standard insect sweeping nets were transferred into tubes containing 70% ethanol and labelled following their preparations according to museum techniques. Seven Triaspis species have been reported from Turkey in this study.

Considering the game of life rules, Wolfram's works about life-like structures and John von Neumann's self-replication, self-maintenance, self-reproduction problems, we developed 2-states and 3-states hexagonal growing algorithms that reach large populations through random initial states. Unlike the game of life, we used six neighbourhoods cellular automata instead of eight or four neighbourhoods. First simulations explained that whether we are able to obtain sort of oscillators, blinkers, and gliders. Inspired by Wolfram's 1D cellular automata complexity and life-like structures, we simulated 2D synchronous, discrete, deterministic cellular automata to reach life-like forms with 2-states cells. The life-like formations and the oscillators have been explained how they contribute to initiating self-maintenance together with self-reproduction and self-replication. After comparing simulation results, we decided to develop the algorithm for another step. Appending a new state to the same algorithm, which we used for reaching life-like structures, led us to experiment new branching and fractal forms. All these studies tried to demonstrate that complex life forms might come from uncomplicated rules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hexagonal%20cellular%20automata" title="hexagonal cellular automata">hexagonal cellular automata</a>, <a href="https://publications.waset.org/abstracts/search?q=self-replication" title=" self-replication"> self-replication</a>, <a href="https://publications.waset.org/abstracts/search?q=self-reproduction" title=" self-reproduction"> self-reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=self-%20maintenance" title=" self- maintenance"> self- maintenance</a> </p> <a href="https://publications.waset.org/abstracts/99380/2d-hexagonal-cellular-automata-the-complexity-of-forms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99380.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">24</span> Self Tuning Controller for Reducing Cycle to Cycle Variations in SI Engine </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alir%C4%B1za%20Kaleli">Alirıza Kaleli</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Akif%20Ceviz"> M.

Minimization of cyclic variations has a great importance in effectively operating near to lean limit, or at low speed and load. The cyclic variations may reduce the power output of the engine, lead to operational instabilities, and result in undesirable engine vibrations and noise. In this study, spark timing is controlled in order to reduce the cyclic variations in spark ignition engines. Firstly, an ARMAX model has developed between spark timing and maximum pressure using system identification techniques. By using this model, the maximum pressure of the next cycle has been predicted. Then, self-tuning minimum variance controller has been designed to change the spark timing for consecutive cycles of the first cylinder of test engine to regulate the in-cylinder maximum pressure. The performance of the proposed controller is illustrated in real time and experimental results show that the controller has a reliable effect on cycle to cycle variations of maximum cylinder pressure when the engine works under low speed conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyclic%20variations" title="cyclic variations">cyclic variations</a>, <a href="https://publications.waset.org/abstracts/search?q=cylinder%20pressure" title=" cylinder pressure"> cylinder pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=SI%20engines" title=" SI engines"> SI engines</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20tuning%20controller" title=" self tuning controller "> self tuning controller </a> </p> <a href="https://publications.waset.org/abstracts/21971/self-tuning-controller-for-reducing-cycle-to-cycle-variations-in-si-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21971.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">481</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Synthesis and Biological Evaluation of Some Benzoxazole Derivatives as Inhibitors of Acetylcholinesterase / Butyrylcholinesterase and Tyrosinase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozlem%20Temiz-Arpaci">Ozlem Temiz-Arpaci</a>, <a href="https://publications.waset.org/abstracts/search?q=Meryem%20Tasci"> Meryem Tasci</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Sezer%20Senol"> Fatma Sezer Senol</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%B0lkay%20Erdogan%20Orhan"> İlkay Erdogan Orhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alzheimer’s disease (AD), a neurodegenerative disorder characterized by a progressive deterioration of memory and cognition, occurs more frequently in elderly people. Current treatment approaches in this disease with the major therapeutic strategy are based on the AChE and BChE inhibition. On the other hand, tyrosinase inhibition has become a target for the treatment of Parkinson’s disease (PD) since this enzyme may play a role in neuromelanin formation in the human brain and could be critical in the formation of dopamine neurotoxicity associated with neurodegeneration linked to PD. Also benzoxazoles are structural isosteres of natural nucleotides that can interact with biopolymers so that benzoxazoles showed a lot of different biological activities. In this study, a series of 2,5-disubstituted-benzoxazole derivatives were synthesized and were evaluated as possible inhibitors of acetylcholinesterase (AChE) / butyrylcholinesterase (BChE) and tyrosinase. The results demonstrated that the compounds exhibited a weak spectrum of AChE / BChE inhibitory activity ranging between 3.92% - 54.32% except compound 8 which showed no activity against AChE and compound 4 which showed no activity against BChE at the specified molar concentrations.

Boosting approach is now being used in machine learning area for these aims as an influential tool. The aim of this study is to show the usage of multivariate tree boosting in this field. The main reason for utilizing this approach in the field of decision-making is the ease solutions of complex relationships. To show how multivariate tree boosting method can be used to identify important features and feature-time interaction, we used the data, which was collected retrospectively from Ankara University Chest Diseases Department records. Dataset includes repeated PF ratio measurements. The follow-up time is planned for 120 hours. A set of different models is tested. In conclusion, main idea of classification with weighed combination of classifiers is a reliable method which was shown with simulations several times. Furthermore, time varying variables will be taken into consideration within this concept and it could be possible to make accurate decisions about regression and survival problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boosted%20multivariate%20trees" title="boosted multivariate trees">boosted multivariate trees</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20data" title=" longitudinal data"> longitudinal data</a>, <a href="https://publications.waset.org/abstracts/search?q=multivariate%20regression%20tree" title=" multivariate regression tree"> multivariate regression tree</a>, <a href="https://publications.waset.org/abstracts/search?q=panel%20data" title=" panel data"> panel data</a> </p> <a href="https://publications.waset.org/abstracts/87009/the-use-of-boosted-multivariate-trees-in-medical-decision-making-for-repeated-measurements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87009.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">203</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> Numerical Investigation on Optimizing Fatigue Life in a Lap Joint Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Zamani">P.

Failure of aircraft lap joints directly depends on the stress field in the joint. An important application of riveting process is in the construction of aircraft fuselage structures. In this paper, a 3D finite element method is carried out in order to optimize residual stress field in a riveted lap joint and also to estimate its fatigue life. In continue, a number of experiments are designed and analyzed using design of experiments (DOE). Then, Taguchi method is used to select an optimized case between different levels of each factor. Besides that, the factor which affects the most on residual stress field is investigated. Such optimized case provides the maximum residual stress field. Fatigue life of the optimized joint is estimated by Paris-Erdogan law. Stress intensity factors (SIFs) are calculated using both finite element analysis and experimental formula. In addition, the effect of residual stress field, geometry, and secondary bending are considered in SIF calculation. A good agreement is found between results of such methods. Comparison between optimized fatigue life and fatigue life of other joints has shown an improvement in the joint’s life. <p class="card-text"><strong>Keywords:</strong> <a
