treated with different herbs into different fish species which were caught from northern Aegean and Marmara Sea. Before samples were packaged under vacuum, herbs had been cut and added at the same ratio into the package. Samples were sliced, the weight of each sample was about 150 g, and packaged under vacuum. During the storage period at 4ºC, taste, odor, texture properties of fish samples treated with sous vide were evaluated by trained panelists. Meanwhile, the effect of different herbs on pH values of the samples was investigated. These results were correlated with sensorial results. Furthermore, the effects of different herbs on L, a, b values of fish samples treated with sous vide were evaluated by color measurement. All sensorial results indicated that the values of samples treated with herbs were higher than that of the control group. Color measurement results and pH values were found parallel with sensorial results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sous%20vide" title="Sous vide">Sous vide</a>, <a href="https://publications.waset.org/abstracts/search?q=fish" title=" fish"> fish</a>, <a href="https://publications.waset.org/abstracts/search?q=herbs" title=" herbs"> herbs</a>, <a href="https://publications.waset.org/abstracts/search?q=consumer%20preferences" title=" consumer preferences"> consumer preferences</a>, <a href="https://publications.waset.org/abstracts/search?q=pH" title=" pH"> pH</a>, <a href="https://publications.waset.org/abstracts/search?q=color%20measurement" title=" color measurement"> color measurement</a> </p> <a href="https://publications.waset.org/abstracts/23986/the-effects-of-sous-vide-technology-combined-with-different-herbals-on-sensorial-and-physical-quality-of-fish-species-caught-in-the-northern-aegean-sea-and-marmara-sea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23986.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">42</span> Investigation of Nutritional Values, Sensorial, Flesh Productivity of Parapenaus longirostris between Populations in the Sea of Marmara and in the Northern Aegean Sea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20G%C3%B6n%C3%BClal">Onur Gönülal</a>, <a href="https://publications.waset.org/abstracts/search?q=Zafer%20Ceylan"> Zafer Ceylan</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BClg%C3%BCn%20F.%20Unal%20Sengor"> Gülgün F.

Microstructure results showed that increase in zinc content changed the secondary phase distribution of the alloys. Mechanical test results demonstrate that with the increasing Zn addition the enhancement of the hardness value by 29%, ultimate tensile strength by 16% and yield strength by 15% can be achieved as well as decreasing of elongation by 33%. The improvement in mechanical properties for Mg-Al–Zn alloys with increasing Zn content up to 3% of weight may be ascribed to second phase strengthening. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnesium" title="magnesium">magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc" title=" zinc"> zinc</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=Mg17Al12" title=" Mg17Al12"> Mg17Al12</a> </p> <a href="https://publications.waset.org/abstracts/61276/effect-of-zinc-additions-on-the-microstructure-and-mechanical-properties-of-mg-3al-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61276.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">422</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> Performance Comparison of a Low Cost Air Quality Sensor with a Commercial Electronic Nose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%9Cnal%20K%C4%B1z%C4%B1l">Ünal Kızıl</a>, <a href="https://publications.waset.org/abstracts/search?q=Levent%20Gen%C3%A7"> Levent Genç</a>, <a href="https://publications.waset.org/abstracts/search?q=Sefa%20Aksu"> Sefa Aksu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Tap%C4%B1n%C3%A7"> Ahmet Tapınç</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Figaro AM-1 sensor module which employs TGS 2600 model gas sensor in air quality assessment was used.

Some the synthetic dyes are highly toxic and/or carcinogenic, and their biodegradation can produce even more toxic aromatic amines. The adsorption procedure is one of the most effective means of removing synthetic dye pollutants, and has been described in a number of previous studies by using the functional polymers. In this study, we investigated the removal of synthetic dyes from aqueous solution by using a functional polymer as an adsorbent material. The effect of initial solution concentration, pH, and contact time on the adsorption capacity of the adsorbent were studied in details. The results showed that functional polymer has a potential to be used as cost-effective and efficient adsorbent for the treatment of aqueous solutions from textile industries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20polymers" title="functional polymers">functional polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=synhetic%20dyes" title=" synhetic dyes"> synhetic dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20parameters" title=" physicochemical parameters"> physicochemical parameters</a> </p> <a href="https://publications.waset.org/abstracts/94325/an-investigation-on-the-removal-of-synthetic-dyes-from-aqueous-solution-by-a-functional-polymer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94325.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">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Chaotic Control, Masking and Secure Communication Approach of Supply Chain Attractor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Unal%20Atakan%20Kahraman">Unal Atakan Kahraman</a>, <a href="https://publications.waset.org/abstracts/search?q=Yilmaz%20Uyaro%C4%9Flu"> Yilmaz Uyaroğlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The chaotic signals generated by chaotic systems have some properties such as randomness, complexity and sensitive dependence on initial conditions, which make them particularly suitable for secure communications.

In this paper, an improved secure communication model is proposed based on control of supply chain management system.

Nowadays, alternative fuels are being used in cement manufacturing in a large scale as a help to provide the necessary energy. The alternative fuels could consist of any disposal like waste plastics, used tires and biomass. It has been suggested that the clinker properties might be affected by using these fuels because of foreign elements incorporation to the composition. Studying the distribution of clinker phases and their chemical composition is possible with scanning electron microscopy (SEM). In this study, clinker samples were produced using different alternative fuels in cement firing kilns. The microstructural observations by back-scattered electrons (BSE) mode in SEM (JEOL JSM-6010LV) showed that the clinker phase distribution was dissimilar in samples prepared with different alternative fuels. The alite to belite (a/b) phase content of samples was quantified by image analysis. The results showed that the a/b varied between 5.2 and 1.5 among samples as the average value for six clinker nodules. The elemental analysis by energy-dispersive x-ray spectroscopy (EDS) mounted on SEM indicated the variation in chemical composition among samples. Higher amounts of sulfur and alkalis seemed to reduce the alite phase formation in clinkers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20fuels" title="alternative fuels">alternative fuels</a>, <a href="https://publications.waset.org/abstracts/search?q=cement%20clinker" title=" cement clinker"> cement clinker</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=SEM" title=" SEM"> SEM</a> </p> <a href="https://publications.waset.org/abstracts/37823/scanning-electron-microscopy-of-cement-clinkers-produced-using-alternative-fuels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37823.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">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Shared Vision System Support for Maintenance Tasks of Wind Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buket%20Celik%20%C3%9Cnal">Buket Celik Ünal</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20%C3%9Cnal"> Onur Ünal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Communication is the most challenging part of maintenance operations. Communication between expert and fieldworker is crucial for effective maintenance and this also affects the safety of the fieldworkers. To support a machine user in a remote collaborative physical task, both, a mobile and a stationary device are needed. Such a system is called a shared vision system and the system supports two people to solve a problem from different places. This system reduces the errors and provides a reliable support for qualified and less qualified users. Through this research, it was aimed to validate the effectiveness of using a shared vision system to facilitate communication between on-site workers and those issuing instructions regarding maintenance or inspection works over long distances. The system is designed with head-worn display which is called a shared vision system. As a part of this study, a substitute system is used and implemented by using a shared vision system for maintenance operation. The benefits of the use of a shared vision system are analyzed and results are adapted to the wind turbines to improve the occupational safety and health for maintenance technicians. The motivation for the research effort in this study can be summarized in the following research questions: -How can expert support technician over long distances during maintenance operation? -What are the advantages of using a shared vision system? Experience from the experiment shows that using a shared vision system is an advantage for both electrical and mechanical system failures. Results support that the shared vision system can be used for wind turbine maintenance and repair tasks. Because wind turbine generator/gearbox and the substitute system have similar failures. Electrical failures, such as voltage irregularities, wiring failures and mechanical failures, such as alignment, vibration, over-speed conditions are the common and similar failures for both. Furthermore, it was analyzed the effectiveness of the shared vision system by using a smart glasses in connection with the maintenance task performed by a substitute system under four different circumstances, namely by using a shared vision system, an audio communication, a smartphone and by yourself condition. A suitable method for determining dependencies between factors measured in Chi Square Test, and Chi Square Test for Independence measured for determining a relationship between two qualitative variables and finally Mann Whitney U Test is used to compare any two data sets. While based on this experiment, no relation was found between the results and the gender. Participants` responses confirmed that the shared vision system is efficient and helpful for maintenance operations. From the results of the research, there was a statistically significant difference in the average time taken by subjects on works using a shared vision system under the other conditions. Additionally, this study confirmed that a shared vision system provides reduction in time to diagnose and resolve maintenance issues, reduction in diagnosis errors, reduced travel costs for experts, and increased reliability in service. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication%20support" title="communication support">communication support</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance%20and%20inspection%20tasks" title=" maintenance and inspection tasks"> maintenance and inspection tasks</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20health%20and%20safety" title=" occupational health and safety"> occupational health and safety</a>, <a href="https://publications.waset.org/abstracts/search?q=shared%20vision%20system" title=" shared vision system"> shared vision system</a> </p> <a href="https://publications.waset.org/abstracts/48026/shared-vision-system-support-for-maintenance-tasks-of-wind-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48026.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">260</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Comparison of Acid and Base Pretreatment of Switchgrass (Panicum virgatum L.) for Bioethanol Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20%C3%9Cmi%CC%87t%20%C3%9Cnal">Mustafa Ümi̇t Ünal</a>, <a href="https://publications.waset.org/abstracts/search?q=Nafi%CC%87z%20%C3%87eli%CC%87kta%C5%9F"> Nafi̇z Çeli̇ktaş</a>, <a href="https://publications.waset.org/abstracts/search?q=Aysun%20%C5%9Eener"> Aysun Şener</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Bet%C3%BCl%20Dolgun"> Sara Betül Dolgun</a>, <a href="https://publications.waset.org/abstracts/search?q=Duygu%20Keser"> Duygu Keser</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to compare acid and base pretreatment of switchgrass for bioethanol production.

In parallel to this, total energy consumption has been growing, rapidly. Unfortunately, domestic energy sources could not meet this energy demand. Hence, there is a need for reliable predictions. For this reason, before making a survey study for the migrated people, an informative questionnaire was prepared to take the opinions of the experts on the main drivers that shape the energy consumption behavior of the migrated people. Totally, 17 experts were answered, and they were analyzed by means of Netica program considering Bayesian belief analysis method. In the analysis, factors affecting energy consumption behaviors as well as strategies, institutions, tools and financing methods to change these behaviors towards efficient consumption were investigated. On the basis of the results, it can be concluded that changing the energy consumption behavior of the migrated people is crucial. In order to be successful, electricity and natural gas prices and tariffs in the market should be arranged considering energy efficiency. In addition, support mechanisms by not only the government but also municipalities should be taken into account while preparing related policies. Also, electric appliance producers should develop and implement strategies and action in favor of the usage of more efficient appliances. Last but not least, non-governmental organizations should support the migrated people to improve their awareness on the efficient consumption for the sustainable future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20belief" title="Bayesian belief">Bayesian belief</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior" title=" behavior"> behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=migrated%20people" title=" migrated people"> migrated people</a> </p> <a href="https://publications.waset.org/abstracts/99605/analyzing-energy-consumption-behavior-of-migrated-population-in-turkey-using-bayesian-belief-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99605.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">111</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> Developing a Town Based Soil Database to Assess the Sensitive Zones in Nutrient Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sefa%20Aksu">Sefa Aksu</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%9Cnal%20K%C4%B1z%C4%B1l"> Ünal Kızıl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For this study, a town based soil database created in Gümüşçay District of Biga Town, Çanakkale, Turkey.

Nanofibers have been studied due to their different and superior physical, chemical and mechanical properties. Poly (lactic acid) (PLA), is a type of biodegradable thermoplastic polyester derived from renewable sources used in biomedical owing to its biocompatibility and biodegradability. In addition, zinc oxide is an antibacterial material and hazelnut shell powder is a filling material. In this study, nanofibers were obtained by adding of different ratio Zinc oxide, (ZnO) and hazelnut shell powder at different concentration into Poly (lactic acid) (PLA) by using electrospinning method which is the most common method to obtain nanofibers. After dissolving the granulated polylactic acids in % 1,% 2,% 3 and% 4 with chloroform solvent, they are homogenized by adding tween and hazelnut shell powder at different ratios and then by electrospinning, nanofibers are obtained. Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), Differential scanning calorimeter (DSC) and physical analysis such as density, electrical conductivity, surface tension, viscosity measurement and antimicrobial test were carried out after production process. The resulting structures of the nanofiber possess antimicrobial and antiseptic properties, which are attractive for biomedical applications. The resulting structures of the nanofiber possess antimicrobial, non toxic, self-cleaning and rigid properties, which are attractive for biomedical applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title="electrospinning">electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=hazelnut%20shell%20powder" title=" hazelnut shell powder"> hazelnut shell powder</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%20%28lactic%20acid%29" title=" poly (lactic acid)"> poly (lactic acid)</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title=" zinc oxide"> zinc oxide</a> </p> <a href="https://publications.waset.org/abstracts/96417/investigation-of-electrospun-composites-nanofiber-of-poly-lactic-acidhazelnut-shell-powderzinc-oxide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96417.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">166</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> Design and Synthesis of Some Oxadiazole Bearing Benzimidazole Derivatives as Potential Epidermal Growth Factor Receptor Inhibitors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Celik">Ismail Celik</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulgun%20Ayhan%20Kilcigil"> Gulgun Ayhan Kilcigil</a>, <a href="https://publications.waset.org/abstracts/search?q=Berna%20Guven"> Berna Guven</a>, <a href="https://publications.waset.org/abstracts/search?q=Zumra%20Kara"> Zumra Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Arzu%20Onay-Besikci"> Arzu Onay-Besikci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Epidermal Growth Factor Receptor is the cell-surface receptor of the ErbB (erythroblastic leukemia viral oncogene homologue receptors) family of tyrosine kinases. It plays a vital role in regulating the proliferation and differentiation of cells. However, a variety of mechanisms, such as EGFR expression, mutation, and ligand-dependent receptor dimerization, are associated with the development of various activated EGFR tumors. EGFR is highly expressed in most solid tumors, including breast, head and neck cancer, non-small cell lung cancer (NSCLC), renal, ovarian, and colon cancers. Thus, specific EGFR inhibition plays one of the key roles in cancer treatment. The compounds used in the treatment as tyrosine kinase inhibitors are known to contain the benzimidazole isosterium indole, pazopanib, and axitinibin indazole rings. In addition, benzimidazoles have been shown to exhibit protein kinase inhibitory activity in addition to their different biological activities.Based on these data, it was planned and synthesized of some oxadiazole bearing benzimidazole derivatives [N-cyclohexyl-5-((2-phenyl/substitutedphenyl-1H-benzo[d]imidazole-1-yl) methyl)-1,3,4-oxadiazole-2-amine]. EGFR kinase inhibitory efficiency of the synthesized compounds was determined by comparing them with a known kinase inhibitor erlotinib in vitro, and two of the compounds bearing phenyl (19a) and 3,4-dibenzyloxyphenyl (21a) ring exhibited significant activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benzimidazole" title="benzimidazole">benzimidazole</a>, <a href="https://publications.waset.org/abstracts/search?q=EGFR%20kinase%20inhibitory" title=" EGFR kinase inhibitory"> EGFR kinase inhibitory</a>, <a href="https://publications.waset.org/abstracts/search?q=oxadiazole" title=" oxadiazole"> oxadiazole</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a> </p> <a href="https://publications.waset.org/abstracts/108680/design-and-synthesis-of-some-oxadiazole-bearing-benzimidazole-derivatives-as-potential-epidermal-growth-factor-receptor-inhibitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108680.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">24</span> Experimental Behavior of Composite Shear Walls Having L Shape Steel Sections in Boundary Regions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Bahad%C4%B1r%20Y%C3%BCksel">S.

The analyses were carried out by using the incompressible Reynold-Averaged-Navier-Stokes equations. While determining the diffuser geometry, a high quality, separation-free flow field with minimum energy loses was particularly aimed. The expansion angle has a critical role on the diffuser hydrodynamic performance. In order obtain a relatively short diffuser length, due to the constructive limitations, and hydrodynamic energy effectiveness, three diffuser sections with varying expansion angles for side and bottom walls were considered. A systematic study was performed to determine the most effective diffuser configuration. The results revealed that the inlet condition of the diffuser greatly affects its flow field. The inclusion of the contraction section in the computations substantially modified the flow topology in the diffuser. The effect of the diffuser flow on the test section flow characteristics was clearly observed. The influence of the introduction of small chamfers at the corners of the diffuser geometry is also presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20diffuser" title="asymmetric diffuser">asymmetric diffuser</a>, <a href="https://publications.waset.org/abstracts/search?q=diffuser%20design" title=" diffuser design"> diffuser design</a>, <a href="https://publications.waset.org/abstracts/search?q=cavitation%20tunnel" title=" cavitation tunnel"> cavitation tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=viscous%20flow" title=" viscous flow"> viscous flow</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics%20%28CFD%29" title=" computational fluid dynamics (CFD)"> computational fluid dynamics (CFD)</a>, <a href="https://publications.waset.org/abstracts/search?q=rans" title=" rans"> rans</a> </p> <a href="https://publications.waset.org/abstracts/62078/viscous-flow-computations-for-the-diffuser-section-of-a-large-cavitation-tunnel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62078.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">362</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> Structural and Histochemical Alterations in the Development of the Stigma in Vibirnum tinus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aslihan%20Cetinbas%20Genc">Aslihan Cetinbas Genc</a>, <a href="https://publications.waset.org/abstracts/search?q=Meral%20%20Unal"> Meral Unal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents the structural and cytochemical alterations of stigma at the stages of pre-anthesis, anthesis and post-anthesis in Vibirnum tinus. Capitate stigma continues with a closed style. The receptive surface of stigma is composed of unicellular papillae which are short and flattened at pre-anthesis stage. The papillae in this stage have dense cytoplasm with small vacuoles and a centrally located nucleus. With the start of anthesis, the stigma widens, papillae lengthen and become cylindrical. At anthesis stage, vacuoles enlarge, and nucleus moves to the base of the cell. At post-anthesis stage, the boundaries of the papillae become less noticeable. As proved by Periodic Acid Schiff procedure, the cytoplasm of papillae is rich in insoluble polysaccharides at all stages of development but it becomes remarkable at post-anthesis, particularly at the sub-papillar area. Although there is no significant difference in the content of protein in all stages of the development, it is more abundant at post-anthesis stage, as in Coomassie Brillant Blue stained sections. The surface of papillae is covered by a cuticle which becomes thicker at post-anthesis, and it gives positive reaction with Sudan Black B and Auramine O. The cuticle is covered by a pellicle stained by Coomassie Brillant Blue, indicating dry type of stigma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=develeopmental%20features" title="develeopmental features">develeopmental features</a>, <a href="https://publications.waset.org/abstracts/search?q=histochemistry" title=" histochemistry"> histochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=stigma" title=" stigma"> stigma</a>, <a href="https://publications.waset.org/abstracts/search?q=Vibirnum%20tinus" title=" Vibirnum tinus"> Vibirnum tinus</a> </p> <a href="https://publications.waset.org/abstracts/60055/structural-and-histochemical-alterations-in-the-development-of-the-stigma-in-vibirnum-tinus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60055.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">247</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> A Decision Support System to Detect the Lumbar Disc Disease on the Basis of Clinical MRI </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yavuz%20Unal">Yavuz Unal</a>, <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Polat"> Kemal Polat</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20Erdinc%20Kocer"> H.

Direct and indirect selling options of hotel rooms have been increased especially with the help of new technologies, i.e. hotel’s own web sites and online booking sites. Although these options emerged as tools for diversifying the distribution channels, vast number of hotels -mostly resort hotels- is still heavily dependent upon international tour operators when selling their products. On the other hand, hotel sector is so vulnerable against crises. Economic, political or any other crisis can affect hotels very badly and so it is critical to have the right balance of distribution channel to avoid the adverse impacts of a crisis. In this study, it is aimed to search the impacts of a general crisis on the selling prices of hotels which have different weights of distribution channels. The study was done in Turkey where various crises occurred in 2015 and 2016 which had great negative impacts on Turkish tourism and led enormous occupancy rate and selling price reductions. 112 upscale resort hotel in Antalya, which is the most popular tourism destination of Turkey, joined to the research. According to the results, hotels with high dependency to international tour operators are more forced to reduce their room prices in crisis time compared to the ones which use their own web sites more. It was also found that the decline in room prices is limited for hotels which are working with national tour operators and travel agencies in crisis time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marketing%20channels" title="marketing channels">marketing channels</a>, <a href="https://publications.waset.org/abstracts/search?q=crisis" title=" crisis"> crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=hotel" title=" hotel"> hotel</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20tour%20operators" title=" international tour operators"> international tour operators</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20travel%20agencies" title=" online travel agencies"> online travel agencies</a> </p> <a href="https://publications.waset.org/abstracts/73096/the-effects-of-distribution-channels-on-the-selling-prices-of-hotels-in-time-of-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73096.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">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> A Comparative Study of Various Control Methods for Rendezvous of a Satellite Couple</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Basaran">Hasan Basaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Emre%20Unal"> Emre Unal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Formation flying of satellites is a mission that involves a relative position keeping of different satellites in the constellation. In this study, different control algorithms are compared with one another in terms of ΔV, velocity increment, and tracking error. Various control methods, covering continuous and impulsive approaches are implemented and tested for satellites flying in low Earth orbit. Feedback linearization, sliding mode control, and model predictive control are designed and compared with an impulsive feedback law, which is based on mean orbital elements. Feedback linearization and sliding mode control approaches have identical mathematical models that include second order Earth oblateness effects. The model predictive control, on the other hand, does not include any perturbations and assumes circular chief orbit. The comparison is done with 4 different initial errors and achieved with velocity increment, root mean square error, maximum steady state error, and settling time. It was observed that impulsive law consumed the least ΔV, while produced the highest maximum error in the steady state. The continuous control laws, however, consumed higher velocity increments and produced lower amounts of tracking errors. Finally, the inversely proportional relationship between tracking error and velocity increment was established. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chief-deputy%20satellites" title="chief-deputy satellites">chief-deputy satellites</a>, <a href="https://publications.waset.org/abstracts/search?q=feedback%20linearization" title=" feedback linearization"> feedback linearization</a>, <a href="https://publications.waset.org/abstracts/search?q=follower-leader%20satellites" title=" follower-leader satellites"> follower-leader satellites</a>, <a href="https://publications.waset.org/abstracts/search?q=formation%20flight" title=" formation flight"> formation flight</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20consumption" title=" fuel consumption"> fuel consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20predictive%20control" title=" model predictive control"> model predictive control</a>, <a href="https://publications.waset.org/abstracts/search?q=rendezvous" title=" rendezvous"> rendezvous</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode" title=" sliding mode"> sliding mode</a> </p> <a href="https://publications.waset.org/abstracts/130417/a-comparative-study-of-various-control-methods-for-rendezvous-of-a-satellite-couple" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130417.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">105</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> Vibration Damping Properties of Electrorheological Materials Based on Chitosan/Perlite Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Cabuk">M.

ER fluids generally are composed of polarisable solid particles dispersed in non-conducting oil. ER fluids are fluids which exhibit. The resistance to motion of the ER fluid can be controlled by adjusting the applied E, due to their fast and reversible changes in their rheological properties presence of E. In this study, a series of chitosan/expanded perlite (CS/EP) composites with different chitosan mass fractions (10%, 20%, and 50%) was used. Characterizations of the composites were carried out by Fourier Transform Infrared (FTIR), X-ray diffraction (XRD) and Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) techniques. Antisedimentation stability and dielectric properties of the composites were also determined. The effects of volume fraction, electric field strength, shear rate, shear stress, and temperature onto ER properties of the CS/EP composite particles dispersed in silicone oil (SO) were investigated in detail. Vibration damping behavior of the CS/EP composites were determined as a function of frequence, storage (Gʹ) and loss (Gʹ ʹ) moduli. It was observed that ER response of the CS/EP/SO ER fluids increased with increasing electric field strength and exhibited the typical shear thinning non-Newtonian viscoelastic behaviors with increasing shear rate. The maximum yield stress was obtained with 1250 Pa under E = 3 kV/mm. Further, the CS/EP/SO ER fluids were observed to sensitive to vibration control by showing reversible viscosity enhancements (Gʹ > Gʹ ʹ).

Urban identity formation includes not only a process of physical nature but also development and change processes that take place in the political, economic, social and cultural values, whether national and international level. Although the concept of urban transformation is basically regarded as the spatial transformation; in fact, it reveals a holistic perspective and transformation based on dialectical relationship existing between the spatial and social relationship. For this reason, urban renewal needs to address as not only spatial but also the impact of spatial transformation on social, cultural and economic. Implementation tools used in the perception of urban transformation are varied concepts such as urban renewal, urban resettlement, urban rehabilitation, urban redevelopment, and urban revitalization. The phenomenon of urban transformation begins with the Industrial Revolution. Until the 1980s, it was interpreted as reconsidering physical fossil on urban environment factor like occurring in rapid urbanization, changing in the spatial structure of the city, concentrating of the population in urban areas. However, after the 1980s, it has resided in a conceptual structure which requires to be addressed physical, economic, social, technological and integrity of information. In conclusion, urban transformation, when it enter the literature as a practice of planning, has been up to date in terms of the conceptual structure and content and also hasn’t remained behind converting itself. Urban transformation still maintains its simplest expression, while it transforms so fast converts the contents. In this study, the relationship between urban design and components of urban transformation were discussed with strategies used as a place in the historical process of urban transformation besides a general evaluation of the concept of urban renewal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conceptual%20approach" title="conceptual approach">conceptual approach</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20identity" title=" urban identity"> urban identity</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20regeneration" title=" urban regeneration"> urban regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20renewal" title=" urban renewal"> urban renewal</a> </p> <a href="https://publications.waset.org/abstracts/61848/a-conceptual-approach-for-evaluating-the-urban-renewal-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61848.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">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Establish a Company in Turkey for Foreigners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mucahit%20Unal">Mucahit Unal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Arslan"> Ibrahim Arslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The New Turkish Commercial Code (TCC) No. 6102 was published in the Official Gazette on February 14, 2011. As stated in the New Turkish Commercial Code No. 6102 and Law No. 6103 on Validity and Application of the Turkish Commercial Code, TCC came into effect on July 1, 2012. The basic purpose of the TCC is to form corporate governance coherent with the international standards; to provide transparency in company management; to adjust the Turkish Commercial Code rules with European Union legislations and to simplify establishing a company for foreigner investors to move investments to Turkish market. In this context according to TCC, joint stock companies and limited liability companies can establish with only one single shareholder; the one single shareholder can be foreigner; all board of director members can be foreigner, also all shareholders and board of director members can be non-resident foreigners. Additionally, TCC does not require physical participation to the general shareholders and board members meetings. TCC allows that the general shareholders and board members meetings can hold in an electronic form and resolution of these meetings may also be approved via electronic signatures. Through this amendment, foreign investors no longer have to deal with red tapes. This amendment also means the TCC prevents foreign companies from incurring unnecessary travel expenses. In accordance with all this amendments about TCC, to invest in Turkish market is easy, simple and transparent for foreigner investors and also investors can establish a company in Turkey, irrespective of nationality or place of residence.

All pilot cadets are gone through physical examination before cadet selection flight in a military hospital. Some cadets may show motion sickness symptoms during this flights. The most common symptoms: Nausea, vomiting, vertigo, headache, anxiety, paresthaesia, asthenia, muscle contraction and excitement. These cadets are examined by flight surgeon, after this flight surgeon and psychologist have an motivational interviewing with these cadets. Method: In this study, we have applied a survey that we question the severity of the symptom to the candidates that have motion sickness after the first sortie. We have questioned the candidate who had a motivational interviewing by the psychologist after the treatment of the flight surgeon that whether the candidate relived the complaints that he has at the previous sortie after the second sortie and whether there is decrease or increase in the severity of the complaints compared to the previous flight. Findings: 15 candidates have applied for the flight surgeon with at least one of the motion sickness symptoms. 11 of the 15 candidates showing motion sickness symptoms after the first flight expressed that their complaints are decreased after the motivational interviewing and 4 of the candidates stated that there are no changes in their complaints. The frequently expressed complaints are nausea, vertigo, headache, exhaustion and vomiting respectively. 7 out of 15 candidates expressed that they have same kind of complains in bus, ship etc. Conclusion: It is observed in our study that only conducting motivational interviewing with the candidates without any organic disorders without giving any drugs has a positive effect on the candidates in terms of motion sickness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeromedicine" title="aeromedicine">aeromedicine</a>, <a href="https://publications.waset.org/abstracts/search?q=candidate" title=" candidate"> candidate</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20sickness" title=" motion sickness"> motion sickness</a>, <a href="https://publications.waset.org/abstracts/search?q=motivational%20interviewing" title=" motivational interviewing"> motivational interviewing</a>, <a href="https://publications.waset.org/abstracts/search?q=pilot" title=" pilot"> pilot</a> </p> <a href="https://publications.waset.org/abstracts/31861/are-there-any-positive-effects-of-motivational-interviewing-on-motion-sickness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31861.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">474</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> Recent Developments and Expectations in the Legal Expenses Insurance in Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C4%B0brahim%20Arslan">İbrahim Arslan</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%BCcahit%20%C3%9Cnal"> Mücahit Ünal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An important issue to ensure justice is to simplify the right to seek justice. But there is a cost of seeking justice in civil law. It costs at least, attorneys' fees and judicial expenses during the beginning and in case of losing a trial. Indeed, most of the people refrain from seeking justice because of these expenses. Therefore, it is not inappropriate to say that the removal of obstacles staying on the way of seeking justice will increase the belief in justice. Legal expenses insurance is a private law contract of insurance in which the insurer is obliged to pay premiums of the insured, to provide the necessary services for the protection of legal interests of the insured person within the agreed scope. This type of insurance is being practiced in the Western world for a long time. The special rights, duties and obligations of the parties to a legal expenses insurance contract shall be governed by the Turkish Commercial Code (TCC) and the contractual agreements which are regularly closed in the form of general terms and conditions. If the number of the legal expenses insurance contracts concluded increase this will definitely improve the percentage of seeking justice before the courts. The general terms and conditions applicable in Turkey generally include litigation costs, referee fees, guarantee fund , enforcement costs , appeal costs borne decision corrections costs. In addition, besides the insured, other family members or the people specified in the policy are protected in the scope of personal/family legal expenses insurance. The commercial law disputes fall outside the scope of coverage in this insurance branch. The insured person chooses his own lawyer and the insurer is not allowed to give advice during the selection of a lawyer. In April 2015, the Prime Minister announced of a new era in the field of legal expenses insurance in Turkey and this announcement excited the insurance industry and legal community. <p
