device that uses surface acoustic waves for rapid lysis of low level of cell samples. The device incorporates sharp-edge glass microparticles for improved performance. We optimized the lysis conditions for high efficiency and evaluated the device's feasibility for point-of-care applications. The microchip contains a 13-finger pair interdigital transducer with a 30-degree focused angle. It generates high-intensity acoustic beams that converge 6 mm away. The microchip operates at a frequency of 16 MHz, exciting Rayleigh waves with a 250 碌m wavelength on the LiNbO3 substrate. Cell lysis occurs when Candida albicans cells and glass particles are placed within the focal area. The high-intensity surface acoustic waves induce centrifugal forces on the cells and glass particles, resulting in cell lysis through lateral forces from the sharp-edge glass particles. We conducted 42 pilot cell lysis experiments to optimize the surface acoustic wave-induced streaming. We varied electrical power, droplet volume, glass particle size, concentration, and lysis time. A regression machine-learning model determined the impact of each parameter on lysis efficiency. Based on these findings, we predicted optimal conditions: electrical signal of 2.5 W, sample volume of 20 碌l, glass particle size below 10 碌m, concentration of 0.2 碌g, and a 5-minute lysis period. Downstream analysis successfully amplified a DNA target fragment directly from the lysate. The study presents an efficient microchip-based cell lysis method employing acoustic streaming and microparticle collisions within microdroplets. Integration of a surface acoustic wave-based lysis chip with an isothermal amplification method enables swift point-of-care applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell%20lysis" title="cell lysis">cell lysis</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20acoustic%20wave" title=" surface acoustic wave"> surface acoustic wave</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-glass%20particle" title=" micro-glass particle"> micro-glass particle</a>, <a href="https://publications.waset.org/abstracts/search?q=droplet" title=" droplet"> droplet</a> </p> <a href="https://publications.waset.org/abstracts/169097/development-of-a-microfluidic-device-for-low-volume-sample-lysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169097.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">79</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> Effects of the Visual and Auditory Stimuli with Emotional Content on Eyewitness Testimony</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C4%B0rem%20Bulut">陌rem Bulut</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Z.%20%20S%C3%B6y%C3%BCk"> Mustafa Z.

In the literature, the number of studies about the reliability of eyewitness testimony is increasing. The study aims to reveal the factors that affect the short-term and long-term visual memory performance of the participants in the event of an accident. In this context, the effect of the emotional content of the accident and the sounds during the accident on visual memory performance was investigated with eye-tracking. According to the results, the presence of visual and auditory stimuli with emotional content during the accident decreases the participants' both short-term and long-term recall performance. Moreover, the data obtained from the eye monitoring device showed that the participants had difficulty in answering even the questions they focused on at the time of the accident. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eye%20tracking" title="eye tracking">eye tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=eyewitness%20testimony" title=" eyewitness testimony"> eyewitness testimony</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20recall" title=" long-term recall"> long-term recall</a>, <a href="https://publications.waset.org/abstracts/search?q=short-term%20recall" title=" short-term recall"> short-term recall</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20memory" title=" visual memory"> visual memory</a> </p> <a href="https://publications.waset.org/abstracts/115650/effects-of-the-visual-and-auditory-stimuli-with-emotional-content-on-eyewitness-testimony" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115650.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">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Changes in Inorganic Element Contents in Potamogeton Natans Exposed to Cement Factory Pollution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yavuz%20Demir">Yavuz Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mucip%20Genisel"> Mucip Genisel</a>, <a href="https://publications.waset.org/abstracts/search?q=Hulya%20Turk"> Hulya Turk</a>, <a href="https://publications.waset.org/abstracts/search?q=Turgay%20Sisman"> Turgay Sisman</a>, <a href="https://publications.waset.org/abstracts/search?q=Serkan%20Erdal"> Serkan Erdal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the changes in contents of inorganic elements in the aquatic plant (Potamogeton natans) as a reflection of the impact of chemical nature pollution in a cement factory region (CFR) was evaluated. For this purpose, P, S, K, Ca, Fe, Cl, Mn, Cu, Zn, Mo, Ni, Si, Al, and Cd concentrations were measured in the aquatic plant (Potamogeton natans) taken from a CFR. As a control, aquatic plant was collected at a distance of 2000 m from the outer zone of the cement factory. Inorganic element compositions were measured by energy dispersive X-ray fluorescence spectrometry (EDXRF). Three aquatic plant exhibited similar changes in contents of microelements and macroelements in their leaves. P, S, K, Cl, Ca, and Mo contents in plant grown in the CFR were reduced significantly compared to control plant, whereas their contents of Al, Mn, Fe, Ni, Cu, Zn and Cd were very high. According to these findings, it is possible that aquatic plant (Potamogeton natans) inhabiting in the vicinity of cement factory sustains the deficiency of important essential elements like P, S, K, Ca, and Mo and greatly accumulate heavy metals like Al, Mn, Fe, Ni, Cu, Zn, and Cd. In addition, results of water analysis showed that heavy metal content such as Cu, Pb, Zn, Co, and Al of water taken from CFR was remarkably high than that of outer zone of CFR. These findings with relation to changes in inorganic composition can contribute to be elucidated of effect mechanism on growth and development of aquatic plant (Potamogeton natans) of pollution resulted from cement factories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquatic%20plant" title="aquatic plant">aquatic plant</a>, <a href="https://publications.waset.org/abstracts/search?q=cement%20factory" title=" cement factory"> cement factory</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal%20pollution" title=" heavy metal pollution"> heavy metal pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=inorganic%20element" title=" inorganic element"> inorganic element</a>, <a href="https://publications.waset.org/abstracts/search?q=Potamogeton%20natans" title=" Potamogeton natans "> Potamogeton natans </a> </p> <a href="https://publications.waset.org/abstracts/45228/changes-in-inorganic-element-contents-in-potamogeton-natans-exposed-to-cement-factory-pollution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45228.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">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> A Named Data Networking Stack for Contiki-NG-OS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sedat%20Bilgili">Sedat Bilgili</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20K.%20Demir"> Alper K.

High interrelation between these functions makes integration very useful. Although there are numerous works on integrated process planning and scheduling and many works on scheduling with due date assignment, there are only a few works on the integration of these three functions. Here we tested the different integration levels of these three functions and found a fully integrated version as the best. We applied genetic search and random search and genetic search was found better compared to the random search. We penalized all earliness, tardiness and due date related costs. Since all these three terms are all undesired, it is better to penalize all of them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=process%20planning" title="process planning">process planning</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling" title=" scheduling"> scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=due-date%20assignment" title=" due-date assignment"> due-date assignment</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20search" title=" random search"> random search</a> </p> <a href="https://publications.waset.org/abstracts/68612/solving-process-planning-and-scheduling-with-number-of-operation-plus-processing-time-due-date-assignment-concurrently-using-a-genetic-search" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68612.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">375</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> Capacity Estimation of Hybrid Automated Repeat Request Protocol for Low Earth Orbit Mega-Constellations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arif%20Armagan%20Gozutok">Arif Armagan Gozutok</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20Kule"> Alper Kule</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Tos"> Burak Tos</a>, <a href="https://publications.waset.org/abstracts/search?q=Selman%20Demirel"> Selman Demirel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wireless communication chain requires effective ways to keep throughput efficiency high while it suffers location-dependent, time-varying burst errors.

Phase shift cavity ring down spectroscopy is not only easy to use but is also capable of overcoming the said problems. This technique compares the phase difference between the signal coming out of the cavity with the reference signal. Detection of any material is made by the phase difference between them. By using this technique, air, water, and isopropyl alcohol can be recognized easily. This Methodology has far-reaching applications and can be used in air pollution detection, human breath analysis and many more. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=materials" title="materials">materials</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20shift" title=" phase shift"> phase shift</a>, <a href="https://publications.waset.org/abstracts/search?q=resonance%20wavelength" title=" resonance wavelength"> resonance wavelength</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20domain%20approach" title=" time domain approach"> time domain approach</a> </p> <a href="https://publications.waset.org/abstracts/107606/material-detection-by-phase-shift-cavity-ring-down-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107606.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">149</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> Flexible Poly(vinylidene fluoride-co-hexafluoropropylene) Nanocomposites Filled with Ternary Nanofillers for Energy Harvesting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Ponnamma">D.

In this study, Leaf samples were taken from the carrot plants grown under drought stress conditions during the harvesting period. The plants were irrigated in three irrigation interval (4, 6 and 8 days) and Irrigation water regime was set up in pots. The changes in activities of antioxidant enzymes such as glutathione reductase (GR), glutathione s-transferase (GST), superoxide dismutase (SOD)) in leaves of black carrot were investigated. The activities of antioxidant enzymes (GR, GST, SOD) were varied significantly with irrigation intervals. The highest value of GR, GST and SOD were determined in the irrigation interval of 6 days. All antioxidant activity values were decreased in 8 days of irrigation interval. As a result of the study, it has been suggested that optimum irrigation intervals for plants can be used in antioxidant enzymes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20enzyme" title="antioxidant enzyme">antioxidant enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=carrot" title=" carrot"> carrot</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20interval" title=" irrigation interval"> irrigation interval</a> </p> <a href="https://publications.waset.org/abstracts/96989/effects-of-irrigation-intervals-on-antioxidant-enzyme-activity-in-black-carrot-leaves-daucus-carota-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96989.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Synergistic Effect of Carbon Nanostructures and Titanium Dioxide Nanotubes on the Piezoelectric Property of Polyvinylidene Fluoride</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deepalekshmi%20Ponnamma">Deepalekshmi Ponnamma</a>, <a href="https://publications.waset.org/abstracts/search?q=Erturk%20Alper"> Erturk Alper</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradeep%20Sharma"> Pradeep Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Al%20Ali%20AlMaadeed"> Mariam Al Ali AlMaadeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Integrating efficient energy harvesting materials into soft, flexible and eco-friendly substrates could yield significant breakthroughs in wearable and flexible electronics.

The experimental results showed that the suspension stability and zeta potential of celestite decreased with ultrasonic treatment. Also, the treatment time, immersion depth of probe, and treatment regime affected the stability of celestite suspension. Secondly, the effect of pre-treatment of the suspension with the ultrasonic process on the shear flocculation of celestite using sodium dodecyl sulfate (SDS) was studied and the variations of the flocculation, zeta potential, and contact angle of the mineral with SDS concentration were presented. It was found that the ultrasonic pre-treatment slightly improved the shear flocculation of celestite particles in accordance with the increase in the contact angles.

Numerical and experimental studies are frequently encountered in the literature to examine the mechanical behavior of 316L stainless steel during the forming process. 316L stainless steel is the most common material used in the production of plate heat exchangers and plate heat exchangers are produced by plastic deformation of the stainless steel. The motivation in this study is to determine the appropriate material model during the simulation of the sheet metal forming process. For this reason, two different material models were examined and Ls-Dyna material cards were created using material test data. These are MAT133_BARLAT_YLD2000 and MAT093_SIMPLIFIED_JOHNSON_COOK. In order to compare results of the tensile test & hydraulic bulge test performed both numerically and experimentally. The obtained results were evaluated comparatively and the most suitable material model was selected for the forming simulation. In future studies, this material model will be used in the numerical modeling of the sheet metal forming process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=316L" title="316L">316L</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20characterization" title=" mechanical characterization"> mechanical characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20forming" title=" metal forming"> metal forming</a>, <a href="https://publications.waset.org/abstracts/search?q=Ls-Dyna" title=" Ls-Dyna"> Ls-Dyna</a> </p> <a href="https://publications.waset.org/abstracts/142507/comparison-of-johnson-cook-and-barlat-material-model-for-316l-stainless-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142507.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">334</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> On the Network Packet Loss Tolerance of SVM Based Activity Recognition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gamze%20Uslu">Gamze Uslu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebnem%20Baydere"> Sebnem Baydere</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20K.%20Demir"> Alper K.

Initially, the classification algorithm we use is evaluated in terms of resilience to random data loss with 3D acceleration sensor data for sitting, lying, walking and standing actions. The results show that the proposed classification method can recognize these activities successfully despite high data loss. Secondly, the effect of differentiated quality of service performance on activity recognition success is measured with activity data acquired from a multi hop wireless sensor network, which introduces high data loss. The effect of number of nodes on the reliability and multi activity classification success is demonstrated in simulation environment.

Usually, proximal muscle-related symptoms and neuropathic findings such as mild axonal peripheral neuropathy have been reported. Sympathetic skin responses are useful in evaluating sudomotor activity of the unmyelinated sympathetic fibers of the autonomic nervous system. Neurocognitive impairment may also be a prominent feature of hypothyroidism, particularly in elderly patients. Electromyographic reaction times as a highly sensitive parameter provides. Objective data concerning cognitive and motor functions. The aim of this study was to evaluate peripheral nerve functions, sympathetic skin response and electroneuromyographic (ENMG) reaction times in euthyroid and subclinically hypothyroid patients with a diagnosis of AIT and compare to those of a control group. Thirty-five euthyroid, 19 patients with subclinical hypothyroidism and 35 age and sex-matched healthy subjects were included in the study. Motor and sensory nerve conduction studies, sympathetic skin responses recorded from hand and foot by stimulating contralateral median nerve and simple reaction times by stimulating tibial nerve and recording from extensor indicis proprius muscle were performed to all patients and control group. Only median nerve sensory conduction velocities of the forearm were slower in patients with AIT compared to the control group (p=0.019). Otherwise, nerve conduction studies and sympathetic skin responses showed no significant difference between the patients and the control group. However, reaction times were shorter in the healthy subjects compared to AIT patients. Prolongation in the reaction times may be considered as a parameter reflecting the alterations in the cognitive functions related to the primary disease process in AIT. Combining sympathetic skin responses with more quantitative tests such as cardiovascular tests and sudomotor axon reflex testing may allow us to determine higher rates of involvement of the autonomic nervous system in AIT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sympathetic%20skin%20response" title="sympathetic skin response">sympathetic skin response</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20reaction%20time" title=" simple reaction time"> simple reaction time</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20autoimmune%20thyroiditis" title=" chronic autoimmune thyroiditis"> chronic autoimmune thyroiditis</a> </p> <a href="https://publications.waset.org/abstracts/120327/sympathetic-skin-response-and-reaction-times-in-chronic-autoimmune-thyroiditis-an-overlooked-electrodiagnostic-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120327.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">147</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> Aerogel Fabrication Via Modified Rapid Supercritical Extraction (RSCE) Process - Needle Valve Pressure Release</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haibo%20Zhao">Haibo Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Andre"> Thomas Andre</a>, <a href="https://publications.waset.org/abstracts/search?q=Katherine%20Avery"> Katherine Avery</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20Kiziltas"> Alper Kiziltas</a>, <a href="https://publications.waset.org/abstracts/search?q=Deborah%20Mielewski"> Deborah Mielewski</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Silica aerogels were fabricated through a modified rapid supercritical extraction (RSCE) process. The silica aerogels were made using a tetramethyl orthosilicate precursor and then placed in a hot press and brought to the supercritical point of the solvent, ethanol. In order to control the pressure release without a pressure controller, a needle valve was used. The resulting aerogels were then characterized for their physical and chemical properties and compared to silica aerogels created using similar methods. The aerogels fabricated using this modified RSCE method were found to have similar properties to those in other papers using the unmodified RSCE method. Silica aerogel infused glass blanket composite, graphene reinforced silica aerogel composite were also successfully fabricated by this new method. The modified RSCE process and system is a prototype for better gas outflow control with a lower cost of equipment setup.

In this study, the necessary input parameters for the modeling study were obtained by performing compression tests in the through-thickness and in-plane directions of paper-based honeycomb sandwich structures. With the obtained parameters, homogeneous and micro-mechanical numerical models were developed in the Ls-Dyna environment. The material card used for the homogeneous model is MAT_MODIFIED_HONEYCOMB, and the material card used for the micromechanical model is MAT_PIECEWISE_LINEAR_PLASTICITY. As a result, the effectiveness of homogeneous and micromechanical modeling approaches for paper-based honeycomb sandwich structure was investigated using force-displacement curves. Densification points and peak points on these curves will be compared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20packaging" title="environmental packaging">environmental packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20characterization" title=" mechanical characterization"> mechanical characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=Ls-Dyna" title=" Ls-Dyna"> Ls-Dyna</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20structure" title=" sandwich structure"> sandwich structure</a> </p> <a href="https://publications.waset.org/abstracts/142508/comparison-of-homogeneous-and-micro-mechanical-modelling-approach-for-paper-honeycomb-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142508.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">200</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> Reliability-based Condition Assessment of Offshore Wind Turbines using SHM data </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caglayan%20Hizal">Caglayan Hizal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Emre%20Demirci"> Hasan Emre Demirci</a>, <a href="https://publications.waset.org/abstracts/search?q=Engin%20Aktas"> Engin Aktas</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20Sezer"> Alper Sezer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Offshore wind turbines consist of a long slender tower with a heavy fixed mass on the top of the tower (nacelle), together with a heavy rotating mass (blades and hub). They are always subjected to environmental loads including wind and wave loads in their service life. This study presents a three-stage methodology for reliability-based condition assessment of offshore wind-turbines against the seismic, wave and wind induced effects considering the soil-structure interaction. In this context, failure criterions are considered as serviceability limits of a monopile supporting an Offshore Wind Turbine: (a) allowable horizontal displacement at pile head should not exceed 0.2 m, (b) rotations at pile head should not exceed 0.5掳. A Bayesian system identification framework is adapted to the classical reliability analysis procedure. Using this framework, a reliability assessment can be directly implemented to the updated finite element model without performing time-consuming methods. For numerical verification, simulation data of the finite model of a real offshore wind-turbine structure is investigated using the three-stage methodology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Offshore%20wind%20turbines" title="Offshore wind turbines">Offshore wind turbines</a>, <a href="https://publications.waset.org/abstracts/search?q=SHM" title=" SHM"> SHM</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20assessment" title=" reliability assessment"> reliability assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=soil-structure%20interaction" title=" soil-structure interaction"> soil-structure interaction</a> </p> <a href="https://publications.waset.org/abstracts/135552/reliability-based-condition-assessment-of-offshore-wind-turbines-using-shm-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135552.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">530</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> Combination of Diuretics and Selective Serotonin Reuptake Inhibitors Leading Severe Hyponatremia: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esra%20Bora">Esra Bora</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20Omeroglu"> Alper Omeroglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeynep%20Pelin%20Polat"> Zeynep Pelin Polat</a>, <a href="https://publications.waset.org/abstracts/search?q=Oguzhan%20Kara"> Oguzhan Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Akdogan"> Fatih Akdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sema%20Ucak%20Basat"> Sema Ucak Basat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hyponatremia is one of the most encountered electrolyte imbalance among all medical fields. It has a wide range of symptoms as well as complications from fatigue to loss of consciousness. Although a lot of factors can cause low sodium levels in serum, combining specific medications can lead to severe hyponatremia in a rapid onset which can cause high mortality and morbidity. The objective of this case report was to underline that prescribing specific medications disregarding their side effects can cause this common electrolyte imbalance but in a more severe manner. In this case report, we present a 46-year-old male patient with a serum sodium level of 104 mEq/L who consumed hydrochlorothiazide for hypertension and was under treatment with selective serotonin reuptake inhibitors (SSRIs) for major depression. The patient had tonic-clonic seizures at the second hour of the treatment and intubation was needed due to loss of consciousness and hypoxia. After proper replacement of sodium with hypertonic solutions in intensive care unit for nine days, extubation indicated. Even in healthy young males, hyponatremia due to two separately prescribed medications can lead life-threatening hyponatremia. Physicians should be aware of the side effects of diuretics, especially hydrochlorothiazides and SSRIs and their combinations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diuretics" title="diuretics">diuretics</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrochlorothiazide" title=" hydrochlorothiazide"> hydrochlorothiazide</a>, <a href="https://publications.waset.org/abstracts/search?q=hyponatremia" title=" hyponatremia"> hyponatremia</a>, <a href="https://publications.waset.org/abstracts/search?q=SSRI" title=" SSRI"> SSRI</a> </p> <a href="https://publications.waset.org/abstracts/104997/combination-of-diuretics-and-selective-serotonin-reuptake-inhibitors-leading-severe-hyponatremia-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104997.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Optimum Design of Steel Space Frames by Hybrid Teaching-Learning Based Optimization and Harmony Search Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alper%20Akin">Alper Akin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Aydogdu"> Ibrahim Aydogdu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents a hybrid metaheuristic algorithm to obtain optimum designs for steel space buildings. The optimum design problem of three-dimensional steel frames is mathematically formulated according to provisions of LRFD-AISC (Load and Resistance factor design of American Institute of Steel Construction). Design constraints such as the strength requirements of structural members, the displacement limitations, the inter-story drift and the other structural constraints are derived from LRFD-AISC specification. In this study, a hybrid algorithm by using teaching-learning based optimization (TLBO) and harmony search (HS) algorithms is employed to solve the stated optimum design problem. These algorithms are two of the recent additions to metaheuristic techniques of numerical optimization and have been an efficient tool for solving discrete programming problems. Using these two algorithms in collaboration creates a more powerful tool and mitigates each other鈥檚 weaknesses. To demonstrate the powerful performance of presented hybrid algorithm, the optimum design of a large scale steel building is presented and the results are compared to the previously obtained results available in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimum%20structural%20design" title="optimum structural design">optimum structural design</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20techniques" title=" hybrid techniques"> hybrid techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching-learning%20based%20optimization" title=" teaching-learning based optimization"> teaching-learning based optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=harmony%20search%20algorithm" title=" harmony search algorithm"> harmony search algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20weight" title=" minimum weight"> minimum weight</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20space%20frame" title=" steel space frame"> steel space frame</a> </p> <a href="https://publications.waset.org/abstracts/25612/optimum-design-of-steel-space-frames-by-hybrid-teaching-learning-based-optimization-and-harmony-search-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25612.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">545</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Classification of Barley Varieties by Artificial Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alper%20Taner">Alper Taner</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20Benal%20Oztekin"> Yesim Benal Oztekin</a>, <a href="https://publications.waset.org/abstracts/search?q=Huseyin%20Duran"> Huseyin Duran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, an Artificial Neural Network (ANN) was developed in order to classify barley varieties. For this purpose, physical properties of barley varieties were determined and ANN techniques were used. The physical properties of 8 barley varieties grown in Turkey, namely thousand kernel weight, geometric mean diameter, sphericity, kernel volume, surface area, bulk density, true density, porosity and colour parameters of grain, were determined and it was found that these properties were statistically significant with respect to varieties. As ANN model, three models, N-l, N-2 and N-3 were constructed. The performances of these models were compared. It was determined that the best-fit model was N-1. In the N-1 model, the structure of the model was designed to be 11 input layers, 2 hidden layers and 1 output layer. Thousand kernel weight, geometric mean diameter, sphericity, kernel volume, surface area, bulk density, true density, porosity and colour parameters of grain were used as input parameter; and varieties as output parameter. R2, Root Mean Square Error and Mean Error for the N-l model were found as 99.99%, 0.00074 and 0.009%, respectively. All results obtained by the N-l model were observed to have been quite consistent with real data. By this model, it would be possible to construct automation systems for classification and cleaning in flourmills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physical%20properties" title="physical properties">physical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title=" artificial neural networks"> artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=barley" title=" barley"> barley</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a> </p> <a href="https://publications.waset.org/abstracts/96350/classification-of-barley-varieties-by-artificial-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96350.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">178</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">15</span> Mathematical Modelling of Ultrasound Pre-Treatment in Microwave Dried Strawberry (Fragaria L.)

Then mathematical modelling was applied to dried fruits by using different experimental thin layer models. The sliced fruits were subjected to ultrasound treatment at a frequency of 40 kHz for 10, 20, and 30 minutes, in an ultrasonic water bath, with a ratio of 1:4 to fruit/water. They are then dried in the microwave (90W). The drying process continued until the product moisture was below 10%. By analyzing the moisture change of the products at a certain time, eight different thin-layer drying models, (Newton, page, modified page, Midilli, Henderson and Pabis, logarithmic, two-term, Wang and Singh) were tested for verification of experimental data. MATLAB R2015a statistical program was used for the modelling, and the best suitable model was determined with R虏adj (coefficient of determination of compatibility), and root mean square error (RMSE) values. According to analysis, the drying model that best describes the drying behavior for both drying conditions was determined as the Midilli model by high R虏adj and low RMSE values. Control, 10, 20, and 30 min US for groups R虏adj and RMSE values was established as respectively; 0,9997- 0,005298; 0,9998- 0,004735; 0,9995- 0,007031; 0,9917-0,02773.

This has been achieved by developing computer programs utilizing BBO algorithm which minimize the cost and the CO2 emission of the RC retaining walls. Objective functions of the optimization problem are defined as the minimized cost, the CO2 emission and weighted aggregate of the cost and the CO2 functions of the RC retaining walls. In the formulation of the optimum design problem, the height and thickness of the stem, the length of the toe projection, the thickness of the stem at base level, the length and thickness of the base, the depth and thickness of the key, the distance from the toe to the key, the number and diameter of the reinforcement bars are treated as design variables. In the formulation of the optimization problem, flexural and shear strength constraints and minimum/maximum limitations for the reinforcement bar areas are derived from American Concrete Institute (ACI 318-14) design code. Moreover, the development length conditions for suitable detailing of reinforcement are treated as a constraint. The obtained optimum designs must satisfy the factor of safety for failure modes (overturning, sliding and bearing), strength, serviceability and other required limitations to attain practically acceptable shapes. To demonstrate the efficiency and robustness of the presented BBO algorithm, the optimum design example for retaining walls is presented and the results are compared to the previously obtained results available in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio%20geography" title="bio geography">bio geography</a>, <a href="https://publications.waset.org/abstracts/search?q=meta-heuristic%20search" title=" meta-heuristic search"> meta-heuristic search</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=retaining%20wall" title=" retaining wall"> retaining wall</a> </p> <a href="https://publications.waset.org/abstracts/25608/biogeography-based-co2-and-cost-optimization-of-rc-cantilever-retaining-walls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25608.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">398</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Omni-Modeler: Dynamic Learning for Pedestrian Redetection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Karnes">Michael Karnes</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20Yilmaz"> Alper Yilmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the application of the omni-modeler towards pedestrian redetection. The pedestrian redetection task creates several challenges when applying deep neural networks (DNN) due to the variety of pedestrian appearance with camera position, the variety of environmental conditions, and the specificity required to recognize one pedestrian from another. DNNs require significant training sets and are not easily adapted for changes in class appearances or changes in the set of classes held in its knowledge domain. Pedestrian redetection requires an algorithm that can actively manage its knowledge domain as individuals move in and out of the scene, as well as learn individual appearances from a few frames of a video. The Omni-Modeler is a dynamically learning few-shot visual recognition algorithm developed for tasks with limited training data availability. The Omni-Modeler adapts the knowledge domain of pre-trained deep neural networks to novel concepts with a calculated localized language encoder. The Omni-Modeler knowledge domain is generated by creating a dynamic dictionary of concept definitions, which are directly updatable as new information becomes available. Query images are identified through nearest neighbor comparison to the learned object definitions. The study presented in this paper evaluates its performance in re-identifying individuals as they move through a scene in both single-camera and multi-camera tracking applications. The results demonstrate that the Omni-Modeler shows potential for across-camera view pedestrian redetection and is highly effective for single-camera redetection with a 93% accuracy across 30 individuals using 64 example images for each individual. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20learning" title="dynamic learning">dynamic learning</a>, <a href="https://publications.waset.org/abstracts/search?q=few-shot%20learning" title=" few-shot learning"> few-shot learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pedestrian%20redetection" title=" pedestrian redetection"> pedestrian redetection</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20recognition" title=" visual recognition"> visual recognition</a> </p> <a href="https://publications.waset.org/abstracts/172265/omni-modeler-dynamic-learning-for-pedestrian-redetection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172265.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">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Periodontal Soft Tissue Sculpturing and Use of Interim Appliance for Rehabilitation of Anterior Edentulousness: Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hande%20Yesil">Hande Yesil</a>, <a href="https://publications.waset.org/abstracts/search?q=Seda%20Aycan%20Altan"> Seda Aycan Altan</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Vehbi%20Bal"> M.

Cumhur Sipahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Fixed partial dentures (FPDs) must fulfill functional requirements such as phonetics, chewing efficiency and esthetics especially in the anterior region. A convex type tissue surface is usually recommended for pontics of FPDs. That pontic design also provides suitable oral hygiene and ease of cleaning. However, high esthetic requirements and correct emergence profile are not always achievable because of the convex shape of adjacent soft tissues. Therefore, the ovate type pontic which fulfills the high esthetic demands of the patients may be a good alternative to the modified ridge lap pontic design. Clinical Report: A female patient referred with the complaint of anterior upper edentulousness. In the oral examination it was determined that teeth 11, 12, 21, 22 were deficient. A thick and convex gingival tissue that may cause aesthetic problems was also observed.. Periodontal augmentation surgery was performed to ensure proper papillary configuration and gingival contour. An interim removable partial denture (IRPD) which applied pressure to operated gingival tissues was fabricated postoperatively. The IRPD was used for 4 weeks and after completion of tissue sculpting, the permanent FPD with an ovate pontic was fabricated and cemented. After a follow-up period of 6 months, not any esthetical and hygienic problem was detected and the patient was satisfied with her prosthesis. Conclusion: It was concluded that shaping of gingival contours with IRPD and use of a FPD with ovate pontic fulfills all esthetic and hygienic requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interim%20appliance" title="interim appliance">interim appliance</a>, <a href="https://publications.waset.org/abstracts/search?q=ovate%20pontic" title=" ovate pontic"> ovate pontic</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20sculpturing" title=" tissue sculpturing"> tissue sculpturing</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed%20partial%20denture" title=" fixed partial denture"> fixed partial denture</a> </p> <a href="https://publications.waset.org/abstracts/27385/periodontal-soft-tissue-sculpturing-and-use-of-interim-appliance-for-rehabilitation-of-anterior-edentulousness-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27385.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">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> The Effects of Lipid Emulsion, Magnesium Sulphate and Metoprolol in Amitryptiline-Induced Cardiovascular Toxicity in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saylav%20Ejder%20Bora">Saylav Ejder Bora</a>, <a href="https://publications.waset.org/abstracts/search?q=Arife%20Erdogan"> Arife Erdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mumin%20Alper%20Erdogan"> Mumin Alper Erdogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Oytun%20Erbas"> Oytun Erbas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismet%20Parlak"> Ismet Parlak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The aim of this study was to evaluate histological, electrical and biochemical effects of metoprolol, lipid emulsion and magnesium sulphate as an alternative method to be used in preventing long QT emergence, that is among the lethal consequences of amitryptiline toxicity. Methods: Thirty Sprague- Dawley male rats were included. Rats were randomly separated into 5 groups. First group was administered saline only while the rest had received amitryptiline 100 mg/kg + saline, 5 mg/kg metoprolol, 20 ml/kg lipid emulsion and 75 mg/kg magnesium sulphate (MgSO4) intraperitoneally. ECG at DI lead, biochemical tests following euthanasia were performed in all groups after 1 hour of administration. Cardiac tissues were removed, sections were prepared and examined. Results: QTc values were significantly shorter in the rest when compared to amitryptiline+ saline group. While lipid emulsion did not affect proBNP and troponin values biochemically as compared to that of the control group, histologically, it was with reduced caspase 3 expression. Though statistically insignificant in the context of biochemical changes, pro-BNP and urea levels were lower in the metoprolol group when compared to controls. Similarly, metoprolol had no statistically significant effect on histological caspase 3 expression in the group that was treated with amitryptiline+metoprolol. On the other hand, there was a statistically significant decrease in Troponin, pro-BNP and urea levels as well as significant decline in histological caspase 3 expression within the MgSO4 group when compared to controls. Conclusion: As still a frequent cause of mortality in emergency units, administration of MgSO4, lipid emulsion and metoprolol might be beneficial in alternative treatment of cardiovascular toxicity caused by tricyclic antidepressant overdose, whether intake would be intentional or accidental. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amitryptiline" title="amitryptiline">amitryptiline</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20toxicity" title="cardiovascular toxicity">cardiovascular toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20QT" title=" long QT"> long QT</a>, <a href="https://publications.waset.org/abstracts/search?q=Rat%20Model" title=" Rat Model"> Rat Model</a> </p> <a href="https://publications.waset.org/abstracts/80037/the-effects-of-lipid-emulsion-magnesium-sulphate-and-metoprolol-in-amitryptiline-induced-cardiovascular-toxicity-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80037.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Compatibility of Sulphate Resisting Cement with Super and Hyper-Plasticizer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alper%20Cumhur">Alper Cumhur</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Baylavl%C4%B1"> Hasan Baylavl谋</a>, <a href="https://publications.waset.org/abstracts/search?q=Eren%20G%C3%B6dek"> Eren G枚dek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Use of superplasticity chemical admixtures in concrete production is widespread all over the world and has become almost inevitable. Super-plasticizers (SPA), extend the setting time of concrete by adsorbing onto cement particles and provide concrete to preserve its fresh state workability properties. Hyper-plasticizers (HPA), as a special type of superplasticizer, provide the production of qualified concretes by increasing the workability properties of concrete, effectively. However, compatibility of cement with super and hyper-plasticizers is quite important for achieving efficient workability in order to produce qualified concretes. In 2011, the EN 197-1 standard is edited and cement classifications were updated. In this study, the compatibility of hyper-plasticizer and CEM I SR0 type sulphate resisting cement (SRC) that firstly classified in EN 197-1 is investigated. Within the scope of the experimental studies, a reference cement mortar was designed with a water/cement ratio of 0.50 confirming to EN 196-1. Fresh unit density of mortar was measured and spread diameters (at 0, 60, 120 min after mix preparation) and setting time of reference mortar were determined with flow table and Vicat tests, respectively. Three mortars are being re-prepared with using both super and hyper-plasticizer confirming to ASTM C494 by 0.50, 0.75 and 1.00% of cement weight. Fresh unit densities, spread diameters and setting times of super and hyper plasticizer added mortars (SPM, HPM) will be determined. Theoretical air-entrainment values of both SPMs and HPMs will be calculated by taking the differences between the densities of plasticizer added mortars and reference mortar. The flow table and Vicat tests are going to be repeated to these mortars and results will be compared. In conclusion, compatibility of SRC with SPA and HPA will be investigated. It is expected that optimum dosages of SPA and HPA will be determined for providing the required workability and setting conditions of SRC mortars, and the advantages/disadvantages of both SPA and HPA will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CEM%20I%20SR0" title="CEM I SR0">CEM I SR0</a>, <a href="https://publications.waset.org/abstracts/search?q=hyper-plasticizer" title=" hyper-plasticizer"> hyper-plasticizer</a>, <a href="https://publications.waset.org/abstracts/search?q=setting%20time" title=" setting time"> setting time</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphate%20resisting%20cement" title=" sulphate resisting cement"> sulphate resisting cement</a>, <a href="https://publications.waset.org/abstracts/search?q=super-plasticizer" title=" super-plasticizer"> super-plasticizer</a>, <a href="https://publications.waset.org/abstracts/search?q=workability" title=" workability"> workability</a> </p> <a href="https://publications.waset.org/abstracts/77835/compatibility-of-sulphate-resisting-cement-with-super-and-hyper-plasticizer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77835.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">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Microfiber Release During Laundry Under Different Rinsing Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fulya%20Asena%20Ulu%C3%A7">Fulya Asena Ulu莽</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Tuzcuo%C4%9Flu"> Ehsan Tuzcuo臒lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%C3%BCl%20Bayraktar"> Song眉l Bayraktar</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Koca"> Burak Koca</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20G%C3%BCrarslan"> Alper G眉rarslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microplastics are contaminants that are widely distributed in the environment with a detrimental ecological effect. Besides this, recent research has proved the existence of microplastics in human blood and organs. Microplastics in the environment can be divided into two main categories: primary and secondary microplastics. Primary microplastics are plastics that are released into the environment as microscopic particles. On the other hand, secondary microplastics are the smaller particles that are shed as a result of the consumption of synthetic materials in textile products as well as other products. Textiles are the main source of microplastic contamination in aquatic ecosystems. Laundry of synthetic textiles (34.8%) accounts for an average annual discharge of 3.2 million tons of primary microplastics into the environment. Recently, microfiber shedding from laundry research has gained traction. However, no comprehensive study was conducted from the standpoint of rinsing parameters during laundry to analyze microfiber shedding. The purpose of the present study is to quantify microfiber shedding from fabric under different rinsing conditions and determine the effective rinsing parameters on microfiber release in a laundry environment. In this regard, a parametric study is carried out to investigate the key factors affecting the microfiber release from a front-load washing machine. These parameters are the amount of water used during the rinsing step and the spinning speed at the end of the washing cycle. Minitab statistical program is used to create a design of the experiment (DOE) and analyze the experimental results. Tests are repeated twice and besides the controlled parameters, other washing parameters are kept constant in the washing algorithm. At the end of each cycle, released microfibers are collected via a custom-made filtration system and weighted with precision balance. The results showed that by increasing the water amount during the rinsing step, the amount of microplastic released from the washing machine increased drastically. Also, the parametric study revealed that increasing the spinning speed results in an increase in the microfiber release from textiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=front%20load" title="front load">front load</a>, <a href="https://publications.waset.org/abstracts/search?q=laundry" title=" laundry"> laundry</a>, <a href="https://publications.waset.org/abstracts/search?q=microfiber" title=" microfiber"> microfiber</a>, <a href="https://publications.waset.org/abstracts/search?q=microfiber%20release" title=" microfiber release"> microfiber release</a>, <a href="https://publications.waset.org/abstracts/search?q=microfiber%20shedding" title=" microfiber shedding"> microfiber shedding</a>, <a href="https://publications.waset.org/abstracts/search?q=microplastic" title=" microplastic"> microplastic</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=rinsing%20parameters" title=" rinsing parameters"> rinsing parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20parameters" title=" washing parameters"> washing parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20machine" title=" washing machine"> washing machine</a> </p> <a href="https://publications.waset.org/abstracts/158164/microfiber-release-during-laundry-under-different-rinsing-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158164.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">97</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">8</span> Effect of Surfactant Concentration on Dissolution of Hydrodynamically Trapped Sparingly Soluble Oil Micro Droplets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adil%20Mustafa">Adil Mustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Erten"> Ahmet Erten</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20Kiraz"> Alper Kiraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Melikhan%20Tanyeri"> Melikhan Tanyeri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Work presented here is based on a novel experimental technique used to hydrodynamically trap oil microdroplets inside a microfluidic chip at the junction of microchannels known as stagnation point. Hydrodynamic trapping has been recently used to trap and manipulate a number of particles starting from microbeads to DNA and single cells. Benzyl Benzoate (BB) is used as droplet material. The microdroplets are trapped individually at stagnation point and their dissolution was observed. Experiments are performed for two concentrations (10mM or 10碌M) of AOT surfactant (Docusate Sodium Salt) and two flow rates for each case. Moreover, experimental data is compared with Zhang-Yang-Mao (ZYM) model which studies dissolution of liquid microdroplets in the presence of a host fluid experiencing extensional creeping flow. Industrial processes like polymer blending systems in which heat or mass transport occurs experience extensional flow and an insight into these phenomena is of significant importance to many industrial processes. The experimental technique exploited here gives an insight into the dissolution of liquid microdroplets under extensional flow regime. The comparison of our experimental results with ZYM model reveals that dissolution of microdroplets at lower surfactant concentration (10碌M) fits the ZYM model at saturation concentration (Cs) value reported in literature (Cs = 15脳10鈦宦矺g\m鲁) while for higher surfactant concentration (10mM) which is also above the critical micelle concentration (CMC) of surfactant (5mM) the data fits ZYM model at (Cs = 45脳10鈦宦矺g\m鲁) which is 3X times the value reported in literature. The difference in Cs value from the literature shows enhancement in dissolution rate of sparingly soluble BB microdroplets at surfactant concentrations higher than CMC. Enhancement in the dissolution of sparingly soluble materials is of great importance in pharmaceutical industry. Enhancement in the dissolution of sparingly soluble drugs is a key research area for drug design industry. The experimental method is also advantageous because it is robust and has no mechanical contact with droplets under study are freely suspended in the fluid as compared existing methods used for testing dissolution of drugs. The experiments also give an insight into CMC measurement for surfactants. <p class="card-text"><strong>Keywords:</strong> <a
