investigated by comparing the results of commercial flutter analysis program ZAERO<sup>©</sup> with wind tunnel tests conducted in Ankara Wind Tunnel (ART). A rectangular polycarbonate (PC) plate, 5x125x1000 mm in dimensions, is used for both numerical and experimental investigations. Analysis and test results are very compatible with each other. A comparison between two different solution methods (<em>g</em> and <em>k-method</em>) of ZAERO<sup>©</sup> is also done. It is seen that, <em>k-method</em> gives closer result than the other one. However, g-method results are on conservative side and it is better to use conservative results namely g-method results. Even if the modal analysis results are used for the flutter analysis for this simple structure, a modal test should be conducted in order to validate the modal analysis results to have accurate flutter analysis results for more complicated structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flutter" title="flutter">flutter</a>, <a href="https://publications.waset.org/abstracts/search?q=plate" title=" plate"> plate</a>, <a href="https://publications.waset.org/abstracts/search?q=subsonic%20flow" title=" subsonic flow"> subsonic flow</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title=" wind tunnel"> wind tunnel</a> </p> <a href="https://publications.waset.org/abstracts/35131/numerical-and-experimental-investigations-of-cantilever-rectangular-plate-structure-on-subsonic-flutter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35131.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">518</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> Design, Fabrication, and Experimental Validation of a Warm Bulge Test System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emine%20Feyza%20%C5%9E%C3%BCk%C3%BCr">Emine Feyza Şükür</a>, <a href="https://publications.waset.org/abstracts/search?q=Mevl%C3%BCt%20T%C3%BCrk%C3%B6z"> Mevlüt Türköz</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Dilme%C3%A7"> Murat Dilmeç</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%BCseyin%20Sel%C3%A7uk%20Halkac%C4%B1"> Hüseyin Selçuk Halkacı</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a warm bulge test system was designed, built and experimentally validated to perform warm bulge tests with all necessary systems.

Correct determination of due dates increases shop floor performance and number of jobs completed on time. This subject has been mentioned widely in the literature. Moreover rules for due date determination have been developed from analytical analysis. When a job arrives to the shop floor, a due date is assigned for delivery.

Advanced forming processes such as hydroforming is one of these attempts. In last decades sheet hydroforming process has an increasing interest, particularly in the automotive and aerospace industries. This process has many advantages such as enhanced formability, the capability to form complex parts, higher dimensional accuracy and surface quality, reduction of tool costs and reduced die wear compared to the conventional sheet metal forming processes. There are two types of sheet hydroforming. One of them is hydromechanical deep drawing (HDD) that is a special drawing process in which pressurized ﬂuid medium is used instead of one of the die half compared to the conventional deep drawing (CDD) process. Another one is sheet hydroforming with die (SHF-D) in which blank is formed with the act of fluid pressure and it takes the shape of die half. In this study, transition of cup height according to cup diameter between the processes was determined by performing simulation of the processes in Finite Element Analysis. Firstly SHF-D process was simulated for 40 mm cup diameter at different cup heights chancing from 10 mm to 30 mm and the cup height to diameter ratio value in which it is not possible to obtain a successful forming was determined. Then the same ratio was checked for a different cup diameter of 60 mm. Then thickness distributions of the cups formed by SHF-D and HDD processes were compared for the cup heights. Consequently, it was found that the thickness distribution in HDD process in the analyses was more uniform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=HDD" title=" HDD"> HDD</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroforming%20sheet%20metal%20forming" title=" hydroforming sheet metal forming"> hydroforming sheet metal forming</a>, <a href="https://publications.waset.org/abstracts/search?q=SHF-D" title=" SHF-D"> SHF-D</a> </p> <a href="https://publications.waset.org/abstracts/37056/numerical-determination-of-transition-of-cup-height-between-hydroforming-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37056.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">429</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">40</span> An Investigation on Ultrasonic Pulse Velocity of Hybrid Fiber Reinforced Concretes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soner%20Guler">Soner Guler</a>, <a href="https://publications.waset.org/abstracts/search?q=Demet%20Yavuz"> Demet Yavuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Refik%20Burak%20Taymu%C5%9F"> Refik Burak Taymuş</a>, <a href="https://publications.waset.org/abstracts/search?q=Fuat%20Korkut"> Fuat Korkut</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Because of the easy applying and not costing too much, ultrasonic pulse velocity (UPV) is one of the most used non-destructive techniques to determine concrete characteristics along with impact-echo, Schmidt rebound hammer (SRH) and pulse-echo.

Compressive strength of concrete was targeted at 35 MPa. UPV testing and compressive strength tests were carried out at the curing age of 28 days. The UPV of concrete containing steel fibers has been found to be higher than plain concrete for all the testing groups.

In the study results, it is seen that MGs affect system stability positively by increasing system loadability margin and has a damper effect on the critical modes of the system and the electromechanical local modes, but they make the damping amount of the electromechanical interarea modes reduce. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eigenvalue%20analysis" title="Eigenvalue analysis">Eigenvalue analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrid" title=" microgrid"> microgrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Hopf%20bifurcation" title=" Hopf bifurcation"> Hopf bifurcation</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillatory%20stability" title=" oscillatory stability"> oscillatory stability</a> </p> <a href="https://publications.waset.org/abstracts/75318/the-effect-of-microgrid-on-power-system-oscillatory-stability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75318.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">292</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> A Decision Support System for Flight Disruptions Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burak%20Erkayman">Burak Erkayman</a>, <a href="https://publications.waset.org/abstracts/search?q=Emin%20Gundogar"> Emin Gundogar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayrettin%20Evirgen"> Hayrettin Evirgen</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Sar%C4%B1"> Murat Sarı</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the increasing competition in recent years, airline companies tend to manage their operations aiming fewer losses in a robust manner.

A morphology transition from needle like structure to hexagonal plates, and then needle-like again has been observed as the DI-H2O was added continuously (0.0 wt% to 3.0wt%).

However, extreme temperatures and pressures can lead to material degradation and failure. Film cooling, a widely employed technique, injects a coolant onto the blade surface to mitigate the effects of hot gas exposure. This research investigates the impact of film cooling on gas turbine engine performance, focusing on its influence on efficiency, longevity, and overall engine performance. Through a comprehensive literature review, computational fluid dynamics simulations, and thermal performance analysis, this study aims to provide insights into optimizing film cooling configurations for enhanced engine performance. The research explores the thermal performance characteristics of turbine blades with and without film cooling, the influence of various film cooling techniques on engine efficiency, and the design factors that optimize film cooling effectiveness.

Building operations had to adjust as non-essential personnel worked from home. But as buildings prepare for personnel to return, they need to plan for safe operations amid new COVID-19 guidelines. In this paper we propose a methodology for capacity and flow modeling of personnel within buildings to safely operate under COVID-19 guidelines. We model personnel flow within buildings by network flows with queuing constraints. We study maximum flow, minimum cost, and minimax objectives. We compare our network flow approach with a simulation model through a case study and present the results. Our results showcase various scenarios of how buildings could be operated under new COVID-19 guidelines and provide a framework for building operators to plan and operate buildings in this new paradigm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20analysis" title="network analysis">network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20simulation" title=" building simulation"> building simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19 "> COVID-19 </a> </p> <a href="https://publications.waset.org/abstracts/128718/building-capacity-and-personnel-flow-modeling-for-operating-amid-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128718.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Effects of Corynebacterium cutis Lysate Administration on Hematology and Biochemistry Parameters with PPR Vaccine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burak%20Dik">Burak Dik</a>, <a href="https://publications.waset.org/abstracts/search?q=Oguzhan%20Avci"> Oguzhan Avci</a>, <a href="https://publications.waset.org/abstracts/search?q=Irmak%20Dik"> Irmak Dik</a>, <a href="https://publications.waset.org/abstracts/search?q=Emre%20Bahcivan"> Emre Bahcivan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to evaluate the effects of alone and combined administration of Peste des petits ruminants (PPR) vaccine with Corynebacterium cutis lysate (CCL) on the hematology and biochemistry parameters levels in sheep. CCL and PPR vaccine changes cell and organ activity. In this study, 12 ewes were divided into equal groups; first group; PPR vaccine was applied only one time 1 mL subcutan of armpit on 6 sheep, and the second group; CCL (1 mL) and PPR vaccine (1 mL) combination were applied only one time subcutan of armpit on 6 sheep. Blood samples were collected before treatment (0. hour, control) and after treatment (1, 3, 7, 14, 21 and 28 days) from the sheep. Plasma and serum samples were evaluated for hematology and biochemistry parameters and there were statistically significant in sheep. In conclusion, combined usage of PPR vaccine with CCL may not influence cells and organs. Repeated CCL treatment with vaccine can create hepatotoxic, renal and bone marrow effects in sheep. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Corynebacterium%20cutis%20lysate" title="Corynebacterium cutis lysate">Corynebacterium cutis lysate</a>, <a href="https://publications.waset.org/abstracts/search?q=hematology" title=" hematology"> hematology</a>, <a href="https://publications.waset.org/abstracts/search?q=peste%20des%20petits%20ruminants" title=" peste des petits ruminants"> peste des petits ruminants</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine" title=" vaccine"> vaccine</a> </p> <a href="https://publications.waset.org/abstracts/50928/effects-of-corynebacterium-cutis-lysate-administration-on-hematology-and-biochemistry-parameters-with-ppr-vaccine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50928.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Expression of ACSS2 Genes in Peripheral Blood Mononuclear Cells of Patients with Alzheimer’s Disease </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Bayram">Ali Bayram</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Uz"> Burak Uz</a>, <a href="https://publications.waset.org/abstracts/search?q=Remzi%20Yi%C4%9Fiter"> Remzi Yiğiter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impairment of lipid metabolism in the central nervous system has been suggested as a critical factor of Alzheimer’s disease (AD) pathogenesis.

In this process, sheet metal blank can be drawn deeper by means of fluid pressure acting on sheet surface in the opposite direction of punch movement. High limiting drawing ratio, good surface quality, less springback characteristic and high dimensional accuracy are some of the advantages of this process. The performance of the HMD process is affected by various process parameters such as fluid pressure, blank holder force, punch-die radius, pre-bulging pressure and height, punch diameter, friction between sheet-die and sheet-punch. The fluid pressure and bank older force are the main loading parameters and affect the formability of HMD process significantly. The punch diameter also influences the limiting drawing ratio (the ratio of initial sheet diameter to punch diameter) of the sheet metal blank. In this research, optimal loading (fluid pressure and blank holder force) profiles were determined for AA 5754-O sheet material through fuzzy control algorithm developed in previous study using LS-DYNA finite element analysis (FEA) software. In the preceding study, the fuzzy control algorithm was developed utilizing geometrical criteria such as thinning and wrinkling. In order to obtain the final desired part with the developed algorithm in terms of the punch diameter requested, the effect of punch diameter, which is the one of the process parameters, on loading profiles was investigated separately using blank thickness of 1 mm. Thus, the practicality of the previously developed fuzzy control algorithm with different punch diameters was clarified. Also, thickness distributions of the sheet metal blank along a curvilinear distance were compared for the FEA in which different punch diameters were used. Consequently, it was found that the use of different punch diameters did not affect the optimal loading profiles too much. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Finite%20Element%20Analysis%20%28FEA%29" title="Finite Element Analysis (FEA)">Finite Element Analysis (FEA)</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20control" title=" fuzzy control"> fuzzy control</a>, <a href="https://publications.waset.org/abstracts/search?q=hydromechanical%20deep%20drawing" title=" hydromechanical deep drawing"> hydromechanical deep drawing</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20loading%20profiles" title=" optimal loading profiles"> optimal loading profiles</a>, <a href="https://publications.waset.org/abstracts/search?q=punch%20diameter" title=" punch diameter"> punch diameter</a> </p> <a href="https://publications.waset.org/abstracts/37109/effect-of-punch-diameter-on-optimal-loading-profiles-in-hydromechanical-deep-drawing-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37109.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">431</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> Extraction of Saponins and Cyclopeptides from Cow Cockle (Vaccaria hispanica (Mill.)

It is an important product due to its superior starch granules, triterpenic saponins, and cyclopeptides suitable for drug delivery. V. hispanica naturally grows in different climatic regions and has genotypes that differ in terms of seed content and composition. Sixty-six V. hispanica seed specimens were collected based on the representation of the distribution in all regions of Turkey and the determination of possible genotypic differences between regions. The seeds, collected from each of the 66 locations, were grown in greenhouse conditions in Akdeniz University, Antalya. Saponin and cyclopeptide contents of the V. hispanica seeds were determined after harvest. Accelerated solvent extraction (ASE) was applied for the extraction of saponins and cyclopeptides. Cyclopeptide (segetalin A) and saponin content of V. hispanica seeds were found in the range of 0.165-0.654 g/100 g and 0.15-1.14 g/100 g, respectively. The results were found to be promising for the seeds from Turkey in terms of saponin content and quality.

In addition, in Hadfield steel, negative strain rate sensitivity is observed due to the DSA. In our study, we incorporated dynamic strain aging onto crystal plasticity computations to predict the local instabilities and corresponding negative strain rate sensitivity. Specifically, the material response of Hadfield steel was obtained from monotonic and strain-rate jump experiments under tensile loading. The strain rate range was adjusted from 10⁻⁴ to 10⁻¹s ⁻¹. The crystal plasticity modeling of the material response was carried out based on Voce-type hardening law and corresponding Voce hardening parameters were determined. The solute pinning effect of carbon atom was incorporated to crystal plasticity simulations at microscale level by computing the shear stress contribution imposed on an arrested dislocation by carbon atom. After crystal plasticity simulations with modifying hardening rule, which takes into account the contribution of DSA, it was seen that the model successfully predicts both the role of DSA and corresponding strain rate sensitivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crystal%20plasticity" title="crystal plasticity">crystal plasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20strain%20aging" title=" dynamic strain aging"> dynamic strain aging</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadfield%20steel" title=" Hadfield steel"> Hadfield steel</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20strain%20rate%20sensitivity" title=" negative strain rate sensitivity"> negative strain rate sensitivity</a> </p> <a href="https://publications.waset.org/abstracts/76918/a-crystal-plasticity-approach-to-model-dynamic-strain-aging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76918.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">21</span> Comparative Spatial Analysis of a Re-Arranged Hospital Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burak%20K%C3%B6ken">Burak Köken</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatice%20D.%20Arslan"> Hatice D.

The hospital buildings which require specialty in spatial relationship solutions during design and self-innovation through the developing technology should survive and keep giving service even after the disasters such as earthquakes. In this study, a hospital building where the load-bearing system was strengthened because of the insufficient earthquake performance and the construction of an additional building was required to meet the increasing need for space was discussed and a comparative spatial evaluation of the hospital building was made with regard to its status before the change and after the change. For this reason, spatial organizations of the building before change and after the change were analyzed by means of Space Syntax method and the effects of the change on space organization parameters were searched by applying an analytical procedure. Using Depthmap UCL software, connectivity, visual mean depth, beta and visual integration analyses were conducted. Based on the data obtained after the analyses, it was seen that the relationships between spaces of the building increased after the change and the building has become more explicit and understandable for the occupants. Furthermore, it was determined according to findings of the analysis that the increase in depth causes difficulty in perceiving the spaces and the changes considering this problem generally ease spatial use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architecture" title="architecture">architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital%20building" title=" hospital building"> hospital building</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20syntax" title=" space syntax"> space syntax</a>, <a href="https://publications.waset.org/abstracts/search?q=strengthening" title=" strengthening"> strengthening</a> </p> <a href="https://publications.waset.org/abstracts/33828/comparative-spatial-analysis-of-a-re-arranged-hospital-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33828.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">521</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> GABARAPL1 (GEC1) mRNA Expression Levels in Patients with Alzheimer's Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Bayram">Ali Bayram</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Uz"> Burak Uz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilhan%20Dolasik"> Ilhan Dolasik</a>, <a href="https://publications.waset.org/abstracts/search?q=Remzi%20Yi%C4%9Fiter"> Remzi Yiğiter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The GABARAP (GABAA-receptor-associated protein) family consists of GABARAP, GABARAPL1 (GABARAP-like 1) and GABARAPL2 (GABARAP-like 2). GABARAPL1, like GABARAP, was described to interact with both GABAA receptor and tubulin, and to be involved in intracellular GABAA receptor trafficking and promoting tubulin polymerization. In addition, GABARAPL1 is thought to be involved in various physiological (autophagosome closure, regulation of circadian rhythms) and/or pathological mechanisms (cancer, neurodegeneration). Alzheimer’s disease (AD) is a progressive neuro degenerative disorder characterized with impaired cognitive functions. Disruption of the GABAergic neuro transmission as well as cholinergic and glutamatergic interactions, may also be involved in the pathogenesis of AD. GABARAPL1 presents a regulated tissue expression and is the most expressed gene among the GABARAP family members in the central nervous system. We, herein, conducted a study to investigate the GABARAPL1 mRNA expression levels in patients with AD. 50 patients with AD and 49 control patients were enrolled to the present study. Messenger RNA expression levels of GABARAPL1 were detected by real-time polymerase chain reaction. GABARAPL1 mRNA expression in AD / control patients was 0,495 (95% confidence interval: 0,404-0,607), p= 0,00000002646. Reduced activity of GABARAPL1 gene might play a role, at least partly, in the pathophysiology of AD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%E2%80%99s%20disease" title="Alzheimer’s disease">Alzheimer’s disease</a>, <a href="https://publications.waset.org/abstracts/search?q=GABARAPL1" title=" GABARAPL1"> GABARAPL1</a>, <a href="https://publications.waset.org/abstracts/search?q=mRNA%20expression" title=" mRNA expression"> mRNA expression</a>, <a href="https://publications.waset.org/abstracts/search?q=RT-PCR" title=" RT-PCR"> RT-PCR</a> </p> <a href="https://publications.waset.org/abstracts/19029/gabarapl1-gec1-mrna-expression-levels-in-patients-with-alzheimers-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19029.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">458</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> Process Optimization of Electrospun Fish Sarcoplasmic Protein Based Nanofibers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sena%20Su">Sena Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Ozbek"> Burak Ozbek</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20M.%20Sahin"> Yesim M.

Among these polymers, proteins from different sources have been extensively employed because of their relative abundance, film forming ability, and nutritional qualities. In this study, the biodegradable composite nanofiber films based on fish sarcoplasmic protein (FSP) were prepared via electrospinning technique. Biodegradable polycaprolactone (PCL) was blended with the FSP to obtain hybrid FSP/PCL nanofiber mats with desirable physical properties. Mixture solutions of FSP and PCL were produced at different concentrations and their density, viscosity, electrical conductivity and surface tension were measured. Mechanical properties of electrospun nanofibers were evaluated. Morphology of composite nanofibers was observed using scanning electron microscopy (SEM). Moreover, Fourier transform infrared spectrometer (FTIR) studies were used for analysis chemical composition of composite nanofibers. This study revealed that the FSP based nanofibers have the potential to be used for different applications such as biodegradable packaging, drug delivery, and wound dressing, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=edible%20film" title="edible film">edible film</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20sarcoplasmic%20protein" title=" fish sarcoplasmic protein"> fish sarcoplasmic protein</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofiber" title=" nanofiber"> nanofiber</a> </p> <a href="https://publications.waset.org/abstracts/68672/process-optimization-of-electrospun-fish-sarcoplasmic-protein-based-nanofibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68672.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">297</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> Religious Discrimination Against Small Business Owners: Evidence from the 1875 Cadastral Survey of Istanbul</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burak%20Unveren">Burak Unveren</a>, <a href="https://publications.waset.org/abstracts/search?q=Ecem%20Uygun"> Ecem Uygun</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zdemi%CC%87r%20Teke"> Özdemi̇r Teke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A large body of literature documents how the Ottoman Empire's economic decline in relation to Western Europe was exacerbated by the unequal legal treatment of its subjects based on creed. Motivated by this debate, we empirically explore whether property taxes collected from businesses in Istanbul discriminated against or favored non-Muslims after the cadastral survey of the capital in 1875. The survey was conducted to determine the property taxes. And the process was potentially susceptible to the biased views of the surveyors who calculated the taxes payable via their subjective appraisals of all real properties. According to our results, in contrast to widely held beliefs regarding 19th-century Istanbul, the number of Muslim shop owners is higher than that of non-Muslims. Moreover, we find evidence for taxes collected from non-Muslim shop and store owners to be higher compared to Muslims, even after controlling for all physical features (e.g., size, location, etc.). These results directly pertain to the fiscal capacity of the Ottoman state and its economic divergence from Europe in the 19th century. Surprisingly, the data also indicates no statistically different tax differentials between male and female property owners. <p class="card-text"><strong>Keywords:</strong> <a
