There are couple isolated states which have capacity to produce nuclear weapons such as Iran and North Korea. In this article, Iran nuclear negotiation was analyzed in terms of its relations especially with The United States in order to find the important factors that affect the course of the ongoing nuclear negotiation. In this sense, the Force Field Analysis was used by determining and setting forth Driving and Restraining Forces of the nuclear negotiations in order to see the big picture and to develop strategies that may improve the long-term ongoing Iran nuclear negotiations. It is found that Iran nuclear negotiation heavily depends on breaking down the idea of Iran’s supporting terrorist organizations and being more transparent about nuclear and uranium enrichment. Also, it was found that Iran has to rebuild its relations with Western countries, especially with the United States. In addition, the counties— who contribute to Iran nuclear negotiations— will need to work on the dynamics and drivers of the Israel and Iran relations in order to peacefully transform the conflict between the two states. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=driving%20force" title="driving force">driving force</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran%20nuclear%20negotiation" title=" Iran nuclear negotiation"> Iran nuclear negotiation</a>, <a href="https://publications.waset.org/abstracts/search?q=restraining%20force" title=" restraining force"> restraining force</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20force%20field%20analysis" title=" the force field analysis"> the force field analysis</a> </p> <a href="https://publications.waset.org/abstracts/103916/a-nuclear-negotiation-qualitative-case-study-with-force-field-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103916.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">158</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> Role of Cryptocurrency in Portfolio Diversification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Arugaslan">Onur Arugaslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajay%20Samant"> Ajay Samant</a>, <a href="https://publications.waset.org/abstracts/search?q=Devrim%20Yaman"> Devrim Yaman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Financial advisors and investors seek new assets which could potentially increase portfolio returns and decrease portfolio risk. Cryptocurrencies represent a relatively new asset class which could serve in both these roles. There has been very little research done in the area of the risk/return tradeoff in a portfolio consisting of fixed income assets, stocks, and cryptocurrency. The objective of this study is a rigorous examination of this issue. The data used in the study are the monthly returns on 4-week US Treasury Bills, S&P Investment Grade Corporate Bond Index, Bitcoin and the S&P 500 Stock Index. The methodology used in the study is the application Modern Portfolio Theory to evaluate the risk-adjusted returns of portfolios with varying combinations of these assets, using Sharpe, Treynor and Jensen Indexes, as well as the Sortino and Modigliani measures. The results of the study would include the ranking of various investment portfolios based on their risk/return characteristics. The conclusions of the study would include objective empirical inference for investors who are interested in including cryptocurrency in their asset portfolios but are unsure of the risk/return implications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20economics" title="financial economics">financial economics</a>, <a href="https://publications.waset.org/abstracts/search?q=portfolio%20diversification" title=" portfolio diversification"> portfolio diversification</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed%20income%20securities" title=" fixed income securities"> fixed income securities</a>, <a href="https://publications.waset.org/abstracts/search?q=cryptocurrency" title=" cryptocurrency"> cryptocurrency</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20indexes" title=" stock indexes"> stock indexes</a> </p> <a href="https://publications.waset.org/abstracts/173618/role-of-cryptocurrency-in-portfolio-diversification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173618.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">73</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> Reading Knowledge Development and Its Phases with Generation Z</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20%C3%96zdemir">Onur Özdemir</a>, <a href="https://publications.waset.org/abstracts/search?q=M.Erhan%20ORHAN"> M.Erhan ORHAN</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge Development (KD) is just one of the important phases of Knowledge Management (KM). KD is the phase in which intelligence is used to see the big picture. In order to understand whether information is important or not, we have to use the intelligence cycle that includes four main steps: aiming, collecting data, processing and utilizing. KD also needs these steps. To make a precise decision, the decision maker has to be aware of his subordinates’ ideas. If the decision maker ignores the ideas of his subordinates or participants of the organization, it is not possible for him to get the target. KD is a way of using wisdom to accumulate the puzzle. If the decision maker does not bring together the puzzle pieces, he cannot get the big picture, and this shows its effects on the battlefield. In order to understand the battlefield, the decision maker has to use the intelligence cycle. To convert information to knowledge, KD is the main means for the intelligence cycle. On the other hand, the “Z Generation” born after the millennium are really the game changers. They have different attitudes from their elders. Their understanding of life is different - the definition of freedom and independence have different meanings to them than others. Decision makers have to consider these factors and rethink their decisions accordingly. This article tries to explain the relation between KD and Generation Z. KD is the main method of target managing. But if leaders neglect their people, the world will be seeing much more movements like the Arab Spring and other insurgencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20development" title="knowledge development">knowledge development</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title=" knowledge management"> knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=generation%20Z" title=" generation Z"> generation Z</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligence%20cycle" title=" intelligence cycle "> intelligence cycle </a> </p> <a href="https://publications.waset.org/abstracts/19492/reading-knowledge-development-and-its-phases-with-generation-z" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19492.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">517</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> Unmanned Systems in Urban Areas </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Beyazkurk">Abdullah Beyazkurk</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20Ozdemir"> Onur Ozdemir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The evolution of warfare has been affected from technological developments to a large extent. Another important factor that affected the evolution of warfare is the space. Technological developments became cornerstones for the organization of the forces on the field, while space of the battlefield gained importance with the introduction of urban areas as 'battlefields'. The use of urban areas as battlefields increased the casualty, while technological developments began to play a remedial role. Thus, the unmanned systems drew attention as the remedy. Today's widely used unmanned aerial vehicles have great effects on the operations. On the other hand, with the increasing urbanization, and the wide use of urban areas as battlefields make it a necessity to benefit from unmanned systems on the ground as well. This study focuses on the use of unmanned aerial systems as well as unmanned ground systems in urban warfare, with regards to their performance and cost affectivity. The study defends that the use of unmanned vehicles will be remedial for increasing casualty rates, while their precision and superhuman capacity will manifest the performance advantage. The findings of this study will help modern armies focus on unmanned systems, especially for the urban, anti-terror, or counter insurgency operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technology" title="technology">technology</a>, <a href="https://publications.waset.org/abstracts/search?q=warfare" title=" warfare"> warfare</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20warfare" title=" urban warfare"> urban warfare</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20systems" title=" unmanned systems"> unmanned systems</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20ground%20vehicles" title=" unmanned ground vehicles"> unmanned ground vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicles" title=" unmanned aerial vehicles"> unmanned aerial vehicles</a> </p> <a href="https://publications.waset.org/abstracts/30438/unmanned-systems-in-urban-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30438.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">354</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> Immigration Of Language From Anatolia To Greenland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Kaya">Onur Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Languages date back thousands of years of formation and journeys through the world. In these journeys and formations, they travel, reach and mixes to the very far corners and languages of the world. In this perspective, in order to analyze such language examples, the analysis of the formation, affection, travel, thus immigration of Anatolian Turkish and Inuit of Greenland is significant. Firstly, it is significant to analyze the historical connections between the Turks in Anatolia and the Inuit people in Greenland. So, the intersection of Turks and Inuit's immigrations in history and all these connections to Greenland and Anatolia will be revealed. Then, it is necessary to analyze the linguistic qualities of Turkish and Inuit languages. For this aim, the linguistic theories and linguistic features of the two languages and their common points will be emphasized. After all these explanations and analyses, the effects of the two languages two each other, common words, and the existence of all these in written and literary works of the two languages will be analyzed and exemplified. Finally, the lecture will focus on two different geographies as, Anatolia and Greenland. The two societies’ historical commonness will be revealed. The immigration and the intersecting locations of the two societies will be analyzed. By means of all this information and within the light of the linguistic theories, the commonness of the two languages, the affections caused by each other, the result of these affections, and their examples in written works will be revealed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=greenland" title="greenland">greenland</a>, <a href="https://publications.waset.org/abstracts/search?q=anatolia" title=" anatolia"> anatolia</a>, <a href="https://publications.waset.org/abstracts/search?q=turk" title=" turk"> turk</a>, <a href="https://publications.waset.org/abstracts/search?q=inuit" title=" inuit"> inuit</a>, <a href="https://publications.waset.org/abstracts/search?q=immigration" title=" immigration"> immigration</a> </p> <a href="https://publications.waset.org/abstracts/172565/immigration-of-language-from-anatolia-to-greenland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172565.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">60</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> Neutron Contamination in 18 MV Medical Linear Accelerator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Karaman">Onur Karaman</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Gunes%20Tanir"> A.

However, photon beam collimator materials in Linear Accelerator (LINAC) head generally contains heavy elements is used and the interaction of bremsstrahlung photon with such heavy nuclei, the neutron can be produced inside the treatment rooms. In radiation therapy, neutron contamination contributes to the risk of secondary malignancies in patients, also physicians working in this field. Since the neutron is more dangerous than photon, it is important to determine neutron dose during radiotherapy treatment. In this study, it is aimed to analyze the effect of field size, distance from axis and depth on the amount of in-field and out-field neutron contamination for ElektaVmat accelerator with 18 MV nominal energy. The photon spectra at the distance of 75, 150, 225, 300 cm from target and on the isocenter of beam were scored for 5x5, 10x10, 20x20, 30x30 and 40x40 cm2 fields. Results demonstrated that the neutron spectra and dose are dependent on field size and distances. Beyond 225 cm of isocenter, the dependence of the neutron dose on field size is minimal. As a result, it is concluded that as the open field increases, neutron dose determined decreases. It is important to remember that when treating with high energy photons, the dose from contamination neutrons must be considered as it is much greater than the photon dose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radiotherapy" title="radiotherapy">radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20contamination" title=" neutron contamination"> neutron contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20accelerators" title=" linear accelerators"> linear accelerators</a>, <a href="https://publications.waset.org/abstracts/search?q=photon" title=" photon"> photon</a> </p> <a href="https://publications.waset.org/abstracts/70366/neutron-contamination-in-18-mv-medical-linear-accelerator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70366.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">348</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> Investigation of Enterotoxigenic Staphylococcus aureus in Kitchen of Catering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%87i%C4%9Fdem%20Sezer">Çiğdem Sezer</a>, <a href="https://publications.waset.org/abstracts/search?q=Aksem%20Aksoy"> Aksem Aksoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Leyla%20Vatansever"> Leyla Vatansever</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study has been done for the purpose of evaluation of public health and identifying of enterotoxigenic Staphyloccocus aureus in kitchen of catering. In the kitchen of catering, samples have been taken by swabs from surface of equipments which are in the salad section, meat section and bakery section. Samples have been investigated with classical cultural methods in terms of Staphyloccocus aureus. Therefore, as a 10x10 cm area was identified (salad, cutting and chopping surfaces, knives, meat grinder, meat chopping surface) samples have been taken with sterile swabs with helping FTS from this area. In total, 50 samples were obtained. In aseptic conditions, Baird-Parker agar (with egg yolk tellurite) surface was seeded with swabs. After 24-48 hours of incubation at 37°C, the black colonies with 1-1.5 mm diameter and which are surrounded by a zone indicating lecithinase activity were identified as S. aureus after applying Gram staining, catalase, coagulase, glucose and mannitol fermentation and termonuclease tests. Genotypic characterization (Staphylococcus genus and S.aureus species spesific) of isolates was performed by PCR. The ELISA test was applied to the isolates for the identification of staphylococcal enterotoxins (SET) A, B, C, D, E in bacterial cultures. Measurements were taken at 450 nm in an ELISA reader using an Ridascreen-Total set ELISA test kit (r-biopharm R4105-Enterotoxin A, B, C, D, E). The results were calculated according to the manufacturer’s instructions. A total of 50 samples of 97 S. aureus was isolated. This number has been identified as 60 with PCR analysis. According to ELISA test, only 1 of 60 isolates were found to be enterotoxigenic. Enterotoxigenic strains were identified from the surface of salad chopping and cutting. In the kitchen of catering, S. aureus identification indicates a significant source of contamination. Especially, in raw consumed salad preparation phase of contamination is very important. This food can be a potential source of food-borne poisoning their terms, and they pose a significant risk to consumers have been identified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20aureus" title="Staphylococcus aureus">Staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=enterotoxin" title=" enterotoxin"> enterotoxin</a>, <a href="https://publications.waset.org/abstracts/search?q=catering" title=" catering"> catering</a>, <a href="https://publications.waset.org/abstracts/search?q=kitchen" title=" kitchen"> kitchen</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a> </p> <a href="https://publications.waset.org/abstracts/15962/investigation-of-enterotoxigenic-staphylococcus-aureus-in-kitchen-of-catering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15962.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">402</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> Offset Dependent Uniform Delay Mathematical Optimization Model for Signalized Traffic Network Using Differential Evolution Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahseen%20Saad">Tahseen Saad</a>, <a href="https://publications.waset.org/abstracts/search?q=Halim%20Ceylan"> Halim Ceylan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Weaver"> Jonathan Weaver</a>, <a href="https://publications.waset.org/abstracts/search?q=Osman%20Nuri%20%C3%87elik"> Osman Nuri Çelik</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20Gungor%20Sahin"> Onur Gungor Sahin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new concept of uniform delay offset dependent mathematical optimization problem is derived as the main objective for this study using a differential evolution algorithm. To control the coordination problem, which depends on offset selection and to estimate uniform delay based on the offset choice in a traffic signal network. The assumption is the periodic sinusoidal function for arrival and departure patterns. The cycle time is optimized at the entry links and the optimized value is used in the non-entry links as a common cycle time. The offset optimization algorithm is used to calculate the uniform delay at each link.

Seeds from soybean cv. Cinsoy and Umut-2002 were evaluated in the laboratory for germination, emergence, cool test at 18°C for 10 days, and cold test at 10°C for 4 days and 25°C for 6 days. Result showed that the initial oil contents of Cinsoy and Umut-2002 and seeds were determined to be 19.8 and 20.1% in main crop, and 18.7 and 22.1% in second crop, respectively. It was determined that a clear difference between main and second crop soybean seed lots for seed vigor was found. Germination and emergence percentage were higher in the seed from second crop cultivation of the cultivars. There was no significant difference in germination percentage in cool and cold test while seedling growth was better in the seeds of second crop soybean. The highest seed vigor index (477.6) was found in the seeds of the cultivars grown at second crop. Standard germination percentage did not give a sensitive separation for determining seed vigor of soybean lots. It was concluded that second crop soybean seeds were found the most suitable for seed production while main crop soybean gave higher protein lower oil content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Glycine%20max%20L." title="Glycine max L.">Glycine max L.</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=emergence" title=" emergence"> emergence</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20content" title=" protein content"> protein content</a>, <a href="https://publications.waset.org/abstracts/search?q=vigor%20test" title=" vigor test "> vigor test </a> </p> <a href="https://publications.waset.org/abstracts/14158/determination-of-the-seed-vigor-of-soybean-cultivated-as-main-and-second-crop-in-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14158.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">40</span> Development of Hydrodynamic Drag Calculation and Cavity Shape Generation for Supercavitating Torpedoes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sertac%20Arslan">Sertac Arslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sezer%20Kefeli"> Sezer Kefeli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, firstly supercavitating phenomenon and supercavity shape design parameters are explained and then drag force calculation methods of high speed supercavitating torpedoes are investigated with numerical techniques and verified with empirical studies. In order to reach huge speeds such as 200, 300 knots for underwater vehicles, hydrodynamic hull drag force which is proportional to density of water (ρ) and square of speed should be reduced. Conventional heavy weight torpedoes could reach up to ~50 knots by classic underwater hydrodynamic techniques. However, to exceed 50 knots and reach about 200 knots speeds, hydrodynamic viscous forces must be reduced or eliminated completely. This requirement revives supercavitation phenomena that could be implemented to conventional torpedoes. Supercavitation is the use of cavitation effects to create a gas bubble, allowing the torpedo to move at huge speed through the water by being fully developed cavitation bubble. When the torpedo moves in a cavitation envelope due to cavitator in nose section and solid fuel rocket engine in rear section, this kind of torpedoes could be entitled as Supercavitating Torpedoes. There are two types of cavitation; first one is natural cavitation, and second one is ventilated cavitation. In this study, disk cavitator is modeled with natural cavitation and supercavitation phenomenon parameters are studied. Moreover, drag force calculation is performed for disk shape cavitator with numerical techniques and compared via empirical studies.

The composite was characterised using IR spectra, XRD, FESEM and Pore size studies. The effects of initial pH, adsorbent dose rate and initial dye concentration on the initial adsorption rate, capacity and dye removal efficiency were investigated. The Langmuir and Freundlich adsorption models were used to define the adsorption equilibrium of dye-adsorbent system mathematically and it was decided that the Langmuir model was more suitable to describe the adsorption equilibrium for the system. In addition, first order, second order and saturation type kinetic models were applied to kinetic data of adsorption and kinetic constants were calculated. It was concluded that the second order and the saturation type kinetic models defined the adsorption data more accurately. Finally, the evaluated thermodynamic parameters of adsorption show a spontaneous and exothermic behavior.

To this end, Dresner and Stone proposed a new intersection control model called Autonomous Intersection Management (AIM). In the AIM simulation, they were examining the problem from a multi-agent perspective, demonstrating that intelligent intersection control can be made more efficient than existing control mechanisms. In this study, autonomous intersection management has been investigated. We extended their works and added a potential-based lane organization layer. In order to distribute vehicles evenly to each lane, this layer triggers vehicles to analyze near lanes, and they change their lane if other lanes have an advantage. We can observe this behavior in real life, such as drivers, change their lane by considering their intuitions. Basic intuition on selecting the correct lane for traffic is selecting a less crowded lane in order to reduce delay. We model that behavior without any change in the AIM workflow. Experiment results show us that intersection performance is directly connected with the vehicle distribution in lanes of roads of intersections. We see the advantage of handling lane management with a potential approach in performance metrics such as average delay of intersection and average travel time. Therefore, lane management and intersection management are problems that need to be handled together. This study shows us that the lane through which vehicles enter the intersection is an effective parameter for intersection management. Our study draws attention to this parameter and suggested a solution for it. We observed that the regulation of AIM inputs, which are vehicles in lanes, was as effective as contributing to aim intersection management. PLO-AIM model outperforms AIM in evaluation metrics such as average delay of intersection and average travel time for reasonable traffic rates, which is in between 600 vehicle/hour per lane to 1300 vehicle/hour per lane. The proposed model reduced the average travel time reduced in between %0.2 - %17.3 and reduced the average delay of intersection in between %1.6 - %17.1 for 4-lane and 6-lane scenarios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AIM%20project" title="AIM project">AIM project</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20intersection%20management" title=" autonomous intersection management"> autonomous intersection management</a>, <a href="https://publications.waset.org/abstracts/search?q=lane%20organization" title=" lane organization"> lane organization</a>, <a href="https://publications.waset.org/abstracts/search?q=potential-based%20approach" title=" potential-based approach"> potential-based approach</a> </p> <a href="https://publications.waset.org/abstracts/133634/plo-aim-potential-based-lane-organization-in-autonomous-intersection-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133634.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">37</span> Investigation of Aerodynamic and Design Features of Twisting Tall Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sinan%20Bilgen">Sinan Bilgen</a>, <a href="https://publications.waset.org/abstracts/search?q=Bekir%20Ozer%20Ay"> Bekir Ozer Ay</a>, <a href="https://publications.waset.org/abstracts/search?q=Nilay%20Sezer%20Uzol"> Nilay Sezer Uzol</a> </p> <p class="card-text"><strong>Abstract:</strong></p> After decades of conventional shapes, irregular forms with complex geometries are getting more popular for form generation of tall buildings all over the world. This trend has recently brought out diverse building forms such as twisting tall buildings. This study investigates both the aerodynamic and design features of twisting tall buildings through comparative analyses. Since twisting a tall building give rise to additional complexities related with the form and structural system, lateral load effects become of greater importance on these buildings. The aim of this study is to analyze the inherent characteristics of these iconic forms by comparing the wind loads on twisting tall buildings with those on their prismatic twins. Through a case study research, aerodynamic analyses of an existing twisting tall building and its prismatic counterpart were performed and the results have been compared. The prismatic twin of the original building were generated by removing the progressive rotation of its floors with the same plan area and story height. Performance-based measures under investigation have been evaluated in conjunction with the architectural design. Aerodynamic effects have been analyzed by both wind tunnel tests and computational methods. High frequency base balance tests and pressure measurements on 3D models were performed to evaluate wind load effects on a global and local scale. Comparisons of flat and real surface models were conducted to further evaluate the effects of the twisting form without façade texture contribution. Comparisons highlighted that, the twisting form under investigation shows better aerodynamic behavior both for along wind but particularly for across wind direction. Compared to the prismatic counterpart; twisting model is superior on reducing vortex-shedding dynamic response by disorganizing the wind vortices. Consequently, despite the difficulties arisen from inherent complexity of twisted forms, they could still be feasible and viable with their attractive images in the realm of tall buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20tests" title="aerodynamic tests">aerodynamic tests</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation%20for%20twisting" title=" motivation for twisting"> motivation for twisting</a>, <a href="https://publications.waset.org/abstracts/search?q=tall%20buildings" title=" tall buildings"> tall buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=twisted%20forms" title=" twisted forms"> twisted forms</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20excitation" title=" wind excitation"> wind excitation</a> </p> <a href="https://publications.waset.org/abstracts/55996/investigation-of-aerodynamic-and-design-features-of-twisting-tall-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55996.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">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Numerical Modelling of Hydrodynamic Drag and Supercavitation Parameters for Supercavitating Torpedoes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sezer%20Kefeli">Sezer Kefeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Serta%C3%A7%20Arslan"> Sertaç Arslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, supercavitationphenomena, and parameters are explained, and hydrodynamic design approaches are investigated for supercavitating torpedoes. In addition, drag force calculation methods ofsupercavitatingvehicles are obtained. Basically, conventional heavyweight torpedoes reach up to ~50 knots by classic hydrodynamic techniques, on the other hand super cavitating torpedoes may reach up to ~200 knots, theoretically. However, in order to reachhigh speeds, hydrodynamic viscous forces have to be reduced or eliminated completely. This necessity is revived the supercavitation phenomena that is implemented to conventional torpedoes. Supercavitation is a type of cavitation, after all, it is more stable and continuous than other cavitation types. The general principle of supercavitation is to separate the underwater vehicle from water phase by surrounding the vehicle with cavitation bubbles. This situation allows the torpedo to operate at high speeds through the water being fully developed cavitation. Conventional torpedoes are entitled as supercavitating torpedoes when the torpedo moves in a cavity envelope due to cavitator in the nose section and solid fuel rocket engine in the rear section. There are two types of supercavitation phase, these are natural and artificial cavitation phases. In this study, natural cavitation is investigated on the disk cavitators based on numerical methods. Once the supercavitation characteristics and drag reduction of natural cavitationare studied on CFD platform, results are verified with the empirical equations. As supercavitation parameters cavitation number (), pressure distribution along axial axes, drag coefficient (C_?) and drag force (D), cavity wall velocity (U_?) and dimensionless cavity shape parameters, which are cavity length (L_?/d_?), cavity diameter(d_ₘ/d_?) and cavity fineness ratio (〖L_?/d〗_ₘ) are investigated and compared with empirical results.

The TlSe samples were grown as large single crystals using the Stockbarger-Bridgman method. The thin films, in the form of Al/TlSe/Al, were deposited on the microscope slide in different thicknesses (300-3000 Å) using thermal evaporation technique at 10-5 Torr. The dielectric properties of (TlSe) thin films, capacitance (C) and dielectric loss factor (tanδ), were measured in a frequency range of 10-105 Hz, and temperatures between 213K and 393K via Broadband Dielectric Spectroscopy analyzer. The dielectric constant (ε’) and the dielectric loss (ε’’) of the thin films were derived from measured parameters (C and tanδ). These results showed that the dielectric properties of TlSe thin films are frequency and temperature dependent. The capacitance and the dielectric constant decrease with increasing frequency and decreasing temperature. The dielectric loss of TlSe thin films decreases with increasing frequency, on the other hand, they increase with increasing temperature and increasing thicknesses. There is two relaxation region in the investigated frequency and temperature interval. These regions can be called as low and high-frequency dispersion regions. Low-frequency dispersion region can be attributed to the polarization of the main part of the chain structure of TlSe while high-frequency dispersion region can be attributed to the polarization of side parts of the structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title="thin films">thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=thallium%20selenide" title=" thallium selenide"> thallium selenide</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20spectroscopy" title=" dielectric spectroscopy"> dielectric spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20compounds" title=" binary compounds"> binary compounds</a> </p> <a href="https://publications.waset.org/abstracts/92950/dielectric-properties-of-thalium-selenide-thin-films-at-radio-wave-frequencies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92950.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">153</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> Vehicle Routing Problem Considering Alternative Roads under Triple Bottom Line Accounting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Kaya">Onur Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilknur%20Tukenmez"> Ilknur Tukenmez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we consider vehicle routing problems on networks with alternative direct links between nodes, and we analyze a multi-objective problem considering the financial, environmental and social objectives in this context. In real life, there might exist several alternative direct roads between two nodes, and these roads might have differences in terms of their lengths and durations. For example, a road might be shorter than another but might require longer time due to traffic and speed limits. Similarly, some toll roads might be shorter or faster but require additional payment, leading to higher costs. We consider such alternative links in our problem and develop a mixed integer linear programming model that determines which alternative link to use between two nodes, in addition to determining the optimal routes for different vehicles, depending on the model objectives and constraints. We consider the minimum cost routing as the financial objective for the company, minimizing the CO2 emissions and gas usage as the environmental objectives, and optimizing the driver working conditions/working hours, and minimizing the risks of accidents as the social objectives. With these objective functions, we aim to determine which routes, and which alternative links should be used in addition to the speed choices on each link. We discuss the results of the developed vehicle routing models and compare their results depending on the system parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicle%20routing" title="vehicle routing">vehicle routing</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20links%20between%20nodes" title=" alternative links between nodes"> alternative links between nodes</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20integer%20linear%20programming" title=" mixed integer linear programming"> mixed integer linear programming</a>, <a href="https://publications.waset.org/abstracts/search?q=triple%20bottom%20line%20accounting" title=" triple bottom line accounting"> triple bottom line accounting</a> </p> <a href="https://publications.waset.org/abstracts/64786/vehicle-routing-problem-considering-alternative-roads-under-triple-bottom-line-accounting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64786.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">407</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> Evaluation of the Benefit of Anti-Endomysial IgA and Anti-Tissue Transglutaminase IgA Antibodies for the Diagnosis of Coeliac Disease in a University Hospital, 2010-2016</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Recep%20Ke%C5%9Fli">Recep Keşli</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20T%C3%BCrky%C4%B1lmaz"> Onur Türkyılmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayriye%20Tokay"> Hayriye Tokay</a>, <a href="https://publications.waset.org/abstracts/search?q=Kas%C4%B1m%20Demir"> Kasım Demir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Coeliac disease (CD) is a primary small intestine disorder caused by high sensitivity to gluten which is present in the crops, characterized by inflammation in the small intestine mucosa. The goal of this study was to determine and to compare the sensitivity and specificity values of anti-endomysial IgA (EMA IgA) (IFA) and anti-tissue transglutaminase IgA (anti-tTG IgA) (ELISA) antibodies in the diagnosis of patients suspected with the CD. Methods: One thousand two hundred seventy three patients, who have applied to gastroenterology and pediatric disease polyclinics of Afyon Kocatepe University ANS Research and Practice Hospital were included into the study between 23.09.2010 and 30.05.2016. Sera samples were investigated by immunofluorescence method for EMA positiveness (Euroimmun, Luebeck, Germany). In order to determine quantitative value of Anti-tTG IgA (EIA) (Orgentec Mainz, Germany) fully automated ELISA device (Alisei, Seac, Firenze, Italy) were used. Results: Out of 1273 patients, 160 were diagnosed with coeliac disease according to ESPGHAN 2012 diagnosis criteria. Out of 160 CD patients, 120 were female, 40 were male. The EMA specificity and sensitivity were calculated as 98% and 80% respectively. Specificity and sensitivity of Anti-tTG IgA were determined as 99% and 96% respectively. Conclusion: The specificity of EMA for CD was excellent because all EMA-positive patients (n = 144) were diagnosed with CD. The presence of human anti-tTG IgA was found as a reliable marker for diagnosis and follow-up the CD. Diagnosis of CD should be established on both the clinical and serologic profiles together. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-endomysial%20antibody" title="anti-endomysial antibody">anti-endomysial antibody</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-tTG%20IgA" title=" anti-tTG IgA"> anti-tTG IgA</a>, <a href="https://publications.waset.org/abstracts/search?q=coeliac%20disease" title=" coeliac disease"> coeliac disease</a>, <a href="https://publications.waset.org/abstracts/search?q=immunofluorescence%20assay%20%28IFA%29" title=" immunofluorescence assay (IFA)"> immunofluorescence assay (IFA)</a> </p> <a href="https://publications.waset.org/abstracts/71750/evaluation-of-the-benefit-of-anti-endomysial-iga-and-anti-tissue-transglutaminase-iga-antibodies-for-the-diagnosis-of-coeliac-disease-in-a-university-hospital-2010-2016" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71750.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">254</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> Investigation of the Use of Surface-Modified Waste Orange Pulp for the Adsorption of Remazol Black B</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ceren%20Karaman">Ceren Karaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20Karaman"> Onur Karaman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The adsorption of Remazol Black B (RBB), an anionic dye, onto dried orange pulp (DOP) adsorbent prepared by only drying and by treating with cetyltrimetylammonium bromide (CTAB), a cationic surfactant, surface-modified orange pulp (SMOP) was studied in a stirred batch experiments system at 25°C. The adsorption of RBB on each adsorbent as a function of surfactant dosage, initial pH of the solution and initial dye concentration was investigated. The optimum amount of CTAB was found to be 25g/l. For RBB adsorption studies, while working pH value for the DOP adsorbent system was determined as 2.0, it was observed that this value shifted to 8.0 when the 25 g/l CTAB treated-orange pulp (SMOP) adsorbent was used. It was obtained that the adsorption rate and capacity increased to a certain value, and the adsorption efficiency decreased with increasing initial RBB concentration for both DOP and SMOP adsorbents at pH 2.0 and pH 8.0. While the highest adsorption capacity for DOP was determined as 62.4 mg/g at pH 2.0, and as 325.0 mg/g for SMOP at pH 8.0. As a result, it can be said that permanent cationic coating of the adsorbent surface by CTAB surfactant shifted the working pH from 2.0 to 8.0 and it increased the dye adsorption rate and capacity of orange pulp much more significantly at pH 8.0. The equilibrium RBB adsorption data on each adsorbent were best described by the Langmuir isotherm model. The adsorption kinetics of RBB on each adsorbent followed a pseudo-second-order model. Moreover, the intraparticle diffusion model was used to describe the kinetic data. It was found that diffusion is not the only rate controlling step. The adsorbent was characterized by the Brunauer–Emmett–Teller (BET) analysis, Fourier-transform-infrared (FTIR) spectroscopy, and scanning-electron-microscopy (SEM). The mechanism for the adsorption of RBB on the SMOP may include hydrophobic interaction, van der Waals interaction, stacking and electrostatic interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=Cetyltrimethylammonium%20Bromide%20%28CTAB%29" title=" Cetyltrimethylammonium Bromide (CTAB)"> Cetyltrimethylammonium Bromide (CTAB)</a>, <a href="https://publications.waset.org/abstracts/search?q=orange%20pulp" title=" orange pulp"> orange pulp</a>, <a href="https://publications.waset.org/abstracts/search?q=Remazol%20Black%20B%20%28RBB%29" title=" Remazol Black B (RBB)"> Remazol Black B (RBB)</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20modification" title=" surface modification"> surface modification</a> </p> <a href="https://publications.waset.org/abstracts/70127/investigation-of-the-use-of-surface-modified-waste-orange-pulp-for-the-adsorption-of-remazol-black-b" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70127.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">248</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Genotypic Variation in the Germination Performance and Seed Vigor of Safflower (Carthamus tinctorius L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Demir%20Kaya">Mehmet Demir Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Engin%20G%C3%B6khan%20Kulan"> Engin Gökhan Kulan</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20%C4%B0leri"> Onur İleri</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C3%BCleyman%20Avc%C4%B1"> Süleyman Avcı</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to variation in seed size, shape and oil content of safflower cultivars, germination and emergence performance have been severely influenced by seed characteristics. This study aimed to determine genotypic variation among safflower genotypes for one thousand seed weight, oil content, germination and seed vigor using electrical conductivity (EC) and cold test. In the study, safflower lines ES37-5, ES38-4, ES43-11, ES55-14 and ES58-11 which were developed by single seed selection method, and Dinçer and Remzibey-05 were used as standard varieties. The genotypes were grown under rainfed conditions in Eskişehir, Turkey with four replications. The seeds of each genotype were subjected to standard germination and emergence test at 25°C for 10 days with four replications and 50 seeds per replicate. Electrical conductivity test was performed at 25°C for 24 h to assess the seed vigor. Also, cold test were applied to each safflower genotype at 10°C for 4 days and 25°C for 6 days. Results showed that oil content of the safflower genotypes were different. The highest oil content was determined in ES43-11 with 36.6% while the lowest was 25.9% in ES38-4. Higher germination and emergence rate were obtained from ES55-14 with 96.5% and 73.0%, respectively. There was no significant difference among the safflower genotypes for EC values. Cold test showed that ES43-11 and ES55-14 gave the maximum germination percentages. It was concluded that genotypic factors except for soil and climatic conditions play an important role for determining seed vigor because safflower genotypes grown at the same condition produced various seed vigor values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carthamus%20tinctorius%20L." title="Carthamus tinctorius L.">Carthamus tinctorius L.</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=emergence" title=" emergence"> emergence</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20test" title=" cold test"> cold test</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a> </p> <a href="https://publications.waset.org/abstracts/14156/genotypic-variation-in-the-germination-performance-and-seed-vigor-of-safflower-carthamus-tinctorius-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14156.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">370</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> Revenue Management of Perishable Products Considering Freshness and Price Sensitive Customers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Kaya">Onur Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Halit%20Bayer"> Halit Bayer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global grocery and supermarket sales are among the largest markets in the world and perishable products such as fresh produce, dairy and meat constitute the biggest section of these markets. Due to their deterioration over time, the demand for these products depends highly on their freshness. They become totally obsolete after a certain amount of time causing a high amount of wastage and decreases in grocery profits. In addition, customers are asking for higher product variety in perishable product categories, leading to less predictable demand per product and to more out-dating. Effective management of these perishable products is an important issue since it is observed that billions of dollars’ worth of food is expired and wasted every month. We consider coordinated inventory and pricing decisions for perishable products with a time and price dependent random demand function. We use stochastic dynamic programming to model this system for both periodically-reviewed and continuously-reviewed inventory systems and prove certain structural characteristics of the optimal solution. We prove that the optimal ordering decision scenario has a monotone structure and the optimal price value decreases by time. However, the optimal price changes in a non-monotonic structure with respect to inventory size. We also analyze the effect of 1 different parameters on the optimal solution through numerical experiments. In addition, we analyze simple-to-implement heuristics, investigate their effectiveness and extract managerial insights. This study gives valuable insights about the management of perishable products in order to decrease wastage and increase profits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=age-dependent%20demand" title="age-dependent demand">age-dependent demand</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20programming" title=" dynamic programming"> dynamic programming</a>, <a href="https://publications.waset.org/abstracts/search?q=perishable%20inventory" title=" perishable inventory"> perishable inventory</a>, <a href="https://publications.waset.org/abstracts/search?q=pricing" title=" pricing"> pricing</a> </p> <a href="https://publications.waset.org/abstracts/48630/revenue-management-of-perishable-products-considering-freshness-and-price-sensitive-customers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48630.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">28</span> Morphological Comparison of the Total Skeletal of (Common Bottlenose Dolphin) Tursiops truncatus and (Harbour Porpoise) Phocoena phocoena</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Ya%C5%9Far">Onur Yaşar</a>, <a href="https://publications.waset.org/abstracts/search?q=Okan%20Bilge"> Okan Bilge</a>, <a href="https://publications.waset.org/abstracts/search?q=Orta%C3%A7%20Onmu%C5%9F"> Ortaç Onmuş</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to investigate and compare the locomotion structures, especially the bone structures, of two different dolphin species, the Common bottlenose dolphin Tursiops truncatus and the Harbor porpoise Phocoena phocoena, and to provide a more detailed and descriptive comparison. To compare the structures of bones of two study species; first, the Spinous Process (SP), Inferior Articular Process (IAP), Laminae Vertebrae (LA), Foramen Vertebrae (FV), Corpus Vertebrae (CV), Transverse Process (TP) were determined and then the length of the Spinous Process (LSP), length of the Foramen Vertebrae (LFV), area of the Corpus Vertebrae (ACV), and length of the Transverse Process (LTP) were measured from the caudal view. The spine consists of a total of 61 vertebrae (7 cervical, 13 thoracic, 14 lumbar, and 27 caudal vertebrae) in the Common bottlenose dolphin, while the Harbor Porpoise has 63 vertebrae (7 cervical, 12 thoracic, 14 lumbar, 30 caudal. In the Common bottlenose dolphin, epiphyseal ossification was between the 21st caudal vertebra and the 27th caudal vertebra, while in the Harbor porpoise, it was observed in all vertebrae. Ankylosing spondylitis was observed in the C1 and C2 vertebrae in the Common bottlenose dolphin and in all cervical vertebrae between C1 and C6 in the Harbor porpoise. We argue that this difference in fused cervical vertebrae between the two species may be due to the fact that the neck movements of the Harbor porpoise in the vertical and horizontal axes are more limited than those of the Common bottlenose dolphin. We also think that as the number of fused cervical vertebrae increases, underwater maneuvers are performed at a wider angle, but to test this idea, we think that different species of dolphins should be compared and the different age groups should be investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anatomy" title="anatomy">anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=morphometry" title=" morphometry"> morphometry</a>, <a href="https://publications.waset.org/abstracts/search?q=vertebrae" title=" vertebrae"> vertebrae</a>, <a href="https://publications.waset.org/abstracts/search?q=common%20bottlenose%20dolphin" title=" common bottlenose dolphin"> common bottlenose dolphin</a>, <a href="https://publications.waset.org/abstracts/search?q=Tursiops%20truncatus" title=" Tursiops truncatus"> Tursiops truncatus</a>, <a href="https://publications.waset.org/abstracts/search?q=harbour%20porpoise" title=" harbour porpoise"> harbour porpoise</a>, <a href="https://publications.waset.org/abstracts/search?q=Phocoena%20phocoena" title=" Phocoena phocoena"> Phocoena phocoena</a> </p> <a href="https://publications.waset.org/abstracts/186749/morphological-comparison-of-the-total-skeletal-of-common-bottlenose-dolphin-tursiops-truncatus-and-harbour-porpoise-phocoena-phocoena" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186749.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">48</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> Determination of Identification and Antibiotic Resistance Rates of Pseudomonas aeruginosa Strains from Various Clinical Specimens in a University Hospital for Two Years, 2013-2015</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Recep%20Kesli">Recep Kesli</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulsah%20Asik"> Gulsah Asik</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengiz%20Demir"> Cengiz Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20Turkyilmaz"> Onur Turkyilmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Pseudomonas aeruginosa (P. aeruginosa) is an important nosocomial pathogen which causes serious hospital infections and is resistant to many commonly used antibiotics. P. aeruginosa can develop resistance during therapy and also it is very resistant to disinfectant chemicals. It may be found in respiratory support devices in hospitals. In this study, the antibiotic resistance of P. aeruginosa strains isolated from bronchial aspiration samples was evaluated retrospectively. Methods: Between October 2013 and September 2015, a total of 318 P. aeruginosa were isolated from clinical samples obtained from various intensive care units and inpatient patients hospitalized at Afyon Kocatepe University, ANS Practice and Research Hospital. Isolated bacteria identified by using both the conventional methods and automated identification system-VITEK 2 (bioMerieux, Marcy l’etoile France). Antibacterial resistance tests were performed by using Kirby-Bauer disc (Oxoid, Hampshire, England) diffusion method following the recommendations of CLSI. Results: Antibiotic resistance rates of identified 318 P. aeruginosa strains were found as follows for tested antibiotics; 32 % amikacin, 42% gentamicin, 43% imipenem, 43% meropenem, 50% ciprofloxacin, 57% levofloxacin, 38% cefepime, 63% ceftazidime, and 85% piperacillin/tazobactam. Conclusion: Resistance profiles change according to years and provinces for P. aeruginosa, so these findings should be considered empirical treatment choices. In this study, the highest and lowest resistance rates found against piperacillin/tazobactam % 85, and amikacin %32. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pseudomonas%20aeruginosa" title="Pseudomonas aeruginosa">Pseudomonas aeruginosa</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20resistance%20rates" title=" antibiotic resistance rates"> antibiotic resistance rates</a>, <a href="https://publications.waset.org/abstracts/search?q=intensive%20care%20unit" title=" intensive care unit"> intensive care unit</a>, <a href="https://publications.waset.org/abstracts/search?q=Pseudomonas%20spp." title=" Pseudomonas spp."> Pseudomonas spp.</a> </p> <a href="https://publications.waset.org/abstracts/49745/determination-of-identification-and-antibiotic-resistance-rates-of-pseudomonas-aeruginosa-strains-from-various-clinical-specimens-in-a-university-hospital-for-two-years-2013-2015" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49745.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">26</span> Prevalence of Mycoplasma hominis and Ureaplasma urealyticum as Causative Agents of Non-Gonococcal Urethritis in Men and Determination of Anti-Bacterial Resistance Rates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Recep%20Ke%C5%9Fli">Recep Keşli</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengiz%20Demir"> Cengiz Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20T%C3%BCrky%C4%B1lmaz"> Onur Türkyılmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The aim of this study was to determine the prevalence of Mycoplasma hominis and Ureaplasma urealyticum as the causative agents in men with non-gonococcal urethtritis, and anti-bacterial resistance rates. Methods: The Study was carried out in the two Medical Microbiology Laboratories belonging to: Konya Education and Research Hospital and ANS Practice and Research Hospital, Afyon Kocatepe University, between January 2012 and December 2015. Urethral samples were obtained from patients by using a swab. Mycoplasma hominis and Ureaplasma urealyticum were detected by using Mycoplasma IST-2 kit (bio-Mérieux, Marcy l'Étoile, France). Neisseria gonorrhoea was excluded by Gram staining and culture methods. Results: Of all the one hundred and eighty-eight male patients with urethritis, forty M. hominis and forty two U. urealyticum were detected. Resistance rates of M. hominis strains against to doxycycline, ofloxacin, erythromycin, tetracycline, ciprofloxacin, azithromycin, clarithromycin, and pristinamycin were found as 5 %, 65 %, 25 %, 5 %, 80 %, 20 %, 20 %, 20 %, 5 %, respectively. Resistance rates of U. urealyticum strains against to doxycycline, ofloxacin, erythromycin, tetracycline, ciprofloxacin, azithromycin, clarithromycin, and pristinamycin were found as 4.7 %, 66.6 %, 23.8 %, 4.75 %, 81 %, 19 %, 19 %, 4.7 % respectively. No resistance was detected against to josamycin, for both the strains. Conclusions: It was concluded that; ciprofloxacin and ofloxacin had the weakest; josamycin, doxycycline, and tetracycline had the strongest in vitro anti-bacterial activity, for treatment of the NGU. So josamycin, doxycycline, and tetracycline should be preferred as the first choice of anti-bacterial agents, for treatment of the patients with non-gonococcal male urethritis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20resistance" title="antimicrobial resistance">antimicrobial resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Mycoplasma%20hominis" title=" Mycoplasma hominis"> Mycoplasma hominis</a>, <a href="https://publications.waset.org/abstracts/search?q=non-gonococcal%20urethritis" title=" non-gonococcal urethritis"> non-gonococcal urethritis</a>, <a href="https://publications.waset.org/abstracts/search?q=Ureaplasma%20urealyticum" title=" Ureaplasma urealyticum"> Ureaplasma urealyticum</a> </p> <a href="https://publications.waset.org/abstracts/71747/prevalence-of-mycoplasma-hominis-and-ureaplasma-urealyticum-as-causative-agents-of-non-gonococcal-urethritis-in-men-and-determination-of-anti-bacterial-resistance-rates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71747.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">249</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> Biosorption of Methylene Blue and Acid Red-88 from Wastewater by Using Cypress Cones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Onur%20Yel">Onur Yel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study represents the removal of harmful dye substances from wastewaters by using waste and cheap adsorbents. Rapid population growth and industrialization occasion anthropogenic pollution which gives irreversible damage to the environment. One of the ways in which water pollution occurs is caused by the release of the dyestuffs in the textile industry. The release of dyestuffs to the environment directly damages the living creatures that have acquired water habitat. Especially, wastewater cannot be used for nutritional purposes. In addition, some adsorbents have mutagenic and/or carcinogenic effects. By blocking photosynthesis, it hinders the inhibition of photosynthetic bacteria in the water, which damages the ecological balance and also causes the formation of malodorous compounds. Moreover, the lack of oxygen can pose a serious danger to the lives of other living organisms that need oxygen. In recent years, some physical and chemical methods are preferred for the removal of dyestuffs. However, the utilization of these methods is expensive. For this reason, the availability of new and cheap adsorbents becomes the more significant issue. In this study, an investigation of various variables on the removal of Methylene Blue and Acid Red-88 dyestuffs from wastewaters by the usage of pulverized cypress cones has been carried out. Thus, various masses of absorbent (0.1-0.25-0.5-1-2-4-5 grams) are used in 50, 100, 150, 200, 300 ppm concentrations of Methylene Blue and Acid Red-88 dyestuffs’ solutions, and with a variety of the interaction time (0.25-0.5-1-2-4-5 hours). The mixtures were centrifuged and the absorbance of the filtrates was measured on a UV spectrophotometer to determine their remaining concentrations. In the study, the highest removal ratio of Acid Red-88 dyestuff was found to be 81% at 200 ppm of dyestuff with 2 grams of adsorbent at 300 minutes. For Methylene Blue experiments, the removal percentage was found as 98% where 2 grams of adsorbent is used in 200 ppm dyestuff solution at 120 minutes of interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acid%20red-88" title="acid red-88">acid red-88</a>, <a href="https://publications.waset.org/abstracts/search?q=biosorption" title=" biosorption"> biosorption</a>, <a href="https://publications.waset.org/abstracts/search?q=methylene%20blue" title=" methylene blue"> methylene blue</a>, <a href="https://publications.waset.org/abstracts/search?q=cypress%20cones" title=" cypress cones"> cypress cones</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20pollution" title=" water pollution"> water pollution</a> </p> <a href="https://publications.waset.org/abstracts/93987/biosorption-of-methylene-blue-and-acid-red-88-from-wastewater-by-using-cypress-cones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93987.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">141</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> Evaluation of Antibiotic Resistance Profiles of Staphlyococci Isolated from Various Clinical Specimens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Recep%20Kesli">Recep Kesli</a>, <a href="https://publications.waset.org/abstracts/search?q=Merih%20Simsek"> Merih Simsek</a>, <a href="https://publications.waset.org/abstracts/search?q=Cengiz%20Demir"> Cengiz Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20Turkyilmaz"> Onur Turkyilmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Goal of this study was to determine the antibiotic resistance of Staphylococcus aureus (S. aureus) and Methicillin resistant staphylococcus aureus (MRSA) strains isolated at Medical Microbiology Laboratory of ANS Application and Research Hospital, Afyon Kocatepe University, Turkey. Methods: S. aureus strains isolated between October 2012 and September 2016, from various clinical specimens were evaluated retrospectively. S. aureus strains were identified by both the conventional methods and automated identification system -VITEK 2 (bio-Mérieux, Marcy l’etoile, France), and Meticillin resistance was verified using oxacillin disk with disk-diffusion method. Antibiotic resistance testing was performed by Kirby-Bauer disc diffusion method according to CLSI criteria, and intermediate susceptible strains were considered as resistant. Results: Seven hundred S.aureus strains which were isolated from various clinical specimens were included in this study. These strains were mostly isolated from blood culture, tissue, wounds and bronchial aspiration. All of 306 (43,7%) were oxacillin resistant. While all the S.aureus strains were found to be susceptible to vancomycin, teicoplanin, daptomycin and linezolid, 38 (9.6 %), 77 (19.5 %), 116 (29.4 %), 152 (38.6 %) and 28 (7.1 %) were found to be resistant aganist to clindamycin, erythromycin, gentamicin, tetracycline and sulfamethoxazole/trimethoprim, retrospectively. Conclusions: Comparing to the Methicillin sensitive staphylococcus aureus (MSSA) strains, increased resistance rates of, trimethoprim-sulfamethoxazole, clindamycin, erythromycin, gentamicin, and tetracycline were observed among the MRSA strains. In this study, the most effective antibiotic on the total of strains was found to be trimethoprim-sulfamethoxazole, the least effective antibiotic on the total of strains was found to be tetracycline. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiotic%20resistance" title="antibiotic resistance">antibiotic resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=MRSA" title=" MRSA"> MRSA</a>, <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20aureus" title=" Staphylococcus aureus"> Staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=VITEK%202" title=" VITEK 2"> VITEK 2</a> </p> <a href="https://publications.waset.org/abstracts/71749/evaluation-of-antibiotic-resistance-profiles-of-staphlyococci-isolated-from-various-clinical-specimens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71749.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">23</span> Microbiota Effect with Cytokine in Hl and NHL Patient Group</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ekin%20Ece%20G%C3%BCrer">Ekin Ece Gürer</a>, <a href="https://publications.waset.org/abstracts/search?q=Tar%C4%B1k%20Onur%20Tiryaki"> Tarık Onur Tiryaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Sevgi%20Kalayo%C4%9Flu%20Be%C5%9F%C4%B1%C5%9F%C4%B1k"> Sevgi Kalayoğlu Beşışık</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Savran%20O%C4%9Fuz"> Fatma Savran Oğuz</a>, <a href="https://publications.waset.org/abstracts/search?q=U%C4%9Fur%20Sezerman"> Uğur Sezerman</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Erdem"> Fatma Erdem</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCl%C5%9Fen%20G%C3%BCnel"> Gülşen Günel</a>, <a href="https://publications.waset.org/abstracts/search?q=D%C3%BCrdane%20Serap%20Kuruca"> Dürdane Serap Kuruca</a>, <a href="https://publications.waset.org/abstracts/search?q=Zerrin%20Akta%C5%9F"> Zerrin Aktaş</a>, <a href="https://publications.waset.org/abstracts/search?q=Oral%20%C3%96nc%C3%BCl"> Oral Öncül</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Chemotherapytreatment in HodgkinLymphomaandNon-HodgkinLymphoma (NHL) diseasescausesgastrointestinalepithelialdamage, disruptstheintestinalmicrobiotabalanceandcausesdysbiosis.

In order to measure the stakes of tourism on the economy, microeconomic and macroeconomic factors are elements of analysis. While microeconomics is limited to an individual perspective, macroeconomics extends to a global perspective and treats the economy as a whole by focusing on social and economic actors in general. It is in this context that this study focuses on macroeconomic variables in order to determine the factors that influence the financial performance of tourism firms in Turkey, which is one of the world's major destinations. The aim of the study is to demonstrate the relationship between macroeconomic variables and the financial performance of tourism firms. Data from 2011 to 2020 are collected, from a sample of 16 companies that represent the tourism sector in Borsa Istanbul. Tobin’s Q ratio, Market to Book ratio, Return on Invested Capital, and Return on Assets as the financial performance indicators were dependent variables of the study. Gross Domestic Products, Inflation, Interest Rates, and Unemployment as macroeconomic indicators were independent variables. Again, Size, Liquidity, Leverage, and Age were control variables of the study. According to the results, value indicators, which are Tobin’s Q ratio and Market to Book ratio, have a statistically significant relationship with Inflation, Interest Rates, and Unemployment. A negative relationship is found between value indicators and Interest rates and a positive relationship between value indicators and Unemployment and Inflation. On the other hand, there is no significant relationship between profit indicators (Return on Invested Capital and Return on Assets) and macroeconomic variables. Accordingly, Interest rates negatively affect the financial performance of tourism firms and stand out as a factor that decreases the value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20performance" title="financial performance">financial performance</a>, <a href="https://publications.waset.org/abstracts/search?q=macroeconomic%20variables" title=" macroeconomic variables"> macroeconomic variables</a>, <a href="https://publications.waset.org/abstracts/search?q=panel%20data" title=" panel data"> panel data</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobin%20Q" title=" Tobin Q"> Tobin Q</a> </p> <a href="https://publications.waset.org/abstracts/149028/the-impact-of-macroeconomic-variables-on-financial-performance-of-tourism-firms-case-of-borsa-istanbul" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149028.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">155</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> Bioinformatic Strategies for the Production of Glycoproteins in Algae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fadi%20Saleh">Fadi Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%87%C4%B1%C4%9Fdem%20Sezer%20Zhmurov"> Çığdem Sezer Zhmurov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biopharmaceuticals represent one of the wildest developing fields within biotechnology, and the biological macromolecules being produced inside cells have a variety of applications for therapies. In the past, mammalian cells, especially CHO cells, have been employed in the production of biopharmaceuticals. This is because these cells can achieve human-like completion of PTM. These systems, however, carry apparent disadvantages like high production costs, vulnerability to contamination, and limitations in scalability. This research is focused on the utilization of microalgae as a bioreactor system for the synthesis of biopharmaceutical glycoproteins in relation to PTMs, particularly N-glycosylation. The research points to a growing interest in microalgae as a potential substitute for more conventional expression systems. A number of advantages exist in the use of microalgae, including rapid growth rates, the lack of common human pathogens, controlled scalability in bioreactors, and the ability of some PTMs to take place. Thus, the potential of microalgae to produce recombinant proteins with favorable characteristics makes this a promising platform in order to produce biopharmaceuticals. The study focuses on the examination of the N-glycosylation pathways across different species of microalgae. This investigation is important as N-glycosylation—the process by which carbohydrate groups are linked to proteins—profoundly influences the stability, activity, and general performance of glycoproteins. Additionally, bioinformatics methodologies are employed to explain the genetic pathways implicated in N-glycosylation within microalgae, with the intention of modifying these organisms to produce glycoproteins suitable for human consumption. In this way, the present comparative analysis of the N-glycosylation pathway in humans and microalgae can be used to bridge both systems in order to produce biopharmaceuticals with humanized glycosylation profiles within the microalgal organisms. The results of the research underline microalgae's potential to help improve some of the limitations associated with traditional biopharmaceutical production systems. The study may help in the creation of a cost-effective and scale-up means of producing quality biopharmaceuticals by modifying microalgae genetically to produce glycoproteins with N-glycosylation that is compatible with humans. Improvements in effectiveness will benefit biopharmaceutical production and the biopharmaceutical sector with this novel, green, and efficient expression platform. This thesis, therefore, is thorough research into the viability of microalgae as an efficient platform for producing biopharmaceutical glycoproteins. Based on the in-depth bioinformatic analysis of microalgal N-glycosylation pathways, a platform for their engineering to produce human-compatible glycoproteins is set out in this work. The findings obtained in this research will have significant implications for the biopharmaceutical industry by opening up a new way of developing safer, more efficient, and economically more feasible biopharmaceutical manufacturing platforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microalgae" title="microalgae">microalgae</a>, <a
