Exact solutions are obtained for nanoparticle fraction field, concentration field, temperature field, stream functions, pressure gradient and pressure rise in terms of axial and transverse coordinates under the restrictions of long wavelength and low Reynolds number.

It consists of several methods to assign fractal characteristics to a dataset which may be a theoretical dataset or a pattern or signal extracted from phenomena including natural geometric objects, sound, market fluctuations, heart rates, digital images, molecular motion, networks, etc. Fractal analysis is now widely used in all areas of science. An important limitation of fractal analysis is that arriving at an empirically determined fractal dimension does not necessarily prove that a pattern is fractal; rather, other essential characteristics have to be considered. For this purpose a Visual C++ based software called FRATSAN (FRActal Time Series ANalyser) was developed which extract information from signals through three measures. These measures are Fractal Dimensions, Jeﬀrey’s Measure and Hurst Exponent. After computing these measures, the software plots the graphs for each measure. Besides computing three measures the software can classify whether the signal is fractal or no. In fact, the software uses a dynamic method of analysis for all the measures. A sliding window is selected with a value equal to 10% of the total number of data entries. This sliding window is moved one data entry at a time to obtain all the measures. This makes the computation very sensitive to slight changes in data, thereby giving the user an acute analysis of the data. In order to test the performance of this software a set of EEG signals was given as input and the results were computed and plotted. This software is useful not only for fundamental fractal analysis of signals but can be used for other purposes. For instance by analyzing the Hurst exponent plot of a given EEG signal in patients with epilepsy the onset of seizure can be predicted by noticing the sudden changes in the plot. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EEG%20signals" title="EEG signals">EEG signals</a>, <a href="https://publications.waset.org/abstracts/search?q=fractal%20analysis" title=" fractal analysis"> fractal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fractal%20dimension" title=" fractal dimension"> fractal dimension</a>, <a href="https://publications.waset.org/abstracts/search?q=hurst%20exponent" title=" hurst exponent"> hurst exponent</a>, <a href="https://publications.waset.org/abstracts/search?q=Je%EF%AC%80rey%E2%80%99s%20measure" title=" Jeﬀrey’s measure"> Jeﬀrey’s measure</a> </p> <a href="https://publications.waset.org/abstracts/18806/fratsan-a-new-software-for-fractal-analysis-of-signals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18806.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">467</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">50</span> Free Will and Compatibilism in Decision Theory: A Solution to Newcomb’s Paradox</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sally%20Heyeon%20Hwang">Sally Heyeon Hwang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Within decision theory, there are normative principles that dictate how one should act in addition to empirical theories of actual behavior. As a normative guide to one’s actual behavior, evidential or causal decision-theoretic equations allow one to identify outcomes with maximal utility values. The choice that each person makes, however, will, of course, differ according to varying assignments of weight and probability values. Regarding these different choices, it remains a subject of considerable philosophical controversy whether individual subjects have the capacity to exercise free will with respect to the assignment of probabilities, or whether instead the assignment is in some way constrained. A version of this question is given a precise form in Richard Jeffrey’s assumption that free will is necessary for Newcomb’s paradox to count as a decision problem. This paper will argue, against Jeffrey, that decision theory does not require the assumption of libertarian freedom. One of the hallmarks of decision-making is its application across a wide variety of contexts; the implications of a background assumption of free will is similarly varied. One constant across the contexts of decision is that there are always at least two levels of choice for a given agent, depending on the degree of prior constraint. Within the context of Newcomb’s problem, when the predictor is attempting to guess the choice the agent will make, he or she is analyzing the determined aspects of the agent such as past characteristics, experiences, and knowledge. On the other hand, as David Lewis’ backtracking argument concerning the relationship between past and present events brings to light, there are similarly varied ways in which the past can actually be dependent on the present. One implication of this argument is that even in deterministic settings, an agent can have more free will than it may seem. This paper will thus argue against the view that a stable background assumption of free will or determinism in decision theory is necessary, arguing instead for a compatibilist decision theory yielding a novel treatment of Newcomb’s problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20theory" title="decision theory">decision theory</a>, <a href="https://publications.waset.org/abstracts/search?q=compatibilism" title=" compatibilism"> compatibilism</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20will" title=" free will"> free will</a>, <a href="https://publications.waset.org/abstracts/search?q=Newcomb%E2%80%99s%20problem" title=" Newcomb’s problem"> Newcomb’s problem</a> </p> <a href="https://publications.waset.org/abstracts/81175/free-will-and-compatibilism-in-decision-theory-a-solution-to-newcombs-paradox" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81175.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">321</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Upon Further Reflection: More on the History, Tripartite Role, and Challenges of the Professoriate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20R.%20Mueller">Jeffrey R.

To this end, there were selected literary words of foreign origin in context (60 contexts) and subjected to careful examination. The study is carried out on two novels by Jeffrey Archer – Not a Penny More, Not a Penny Less and A Prisoner of Birth – who, being a graduate from Oxford, represents socially privileged classes himself and gives a wide depiction of characters with different social backgrounds and statuses. The analysis of the novels enabled us to categorize the selected words into four relevant groups. The first represented by terms (commodity, debenture, recuperation, syringe, luminescence, umpire, etc.) serves to unambiguously indicate education, occupation, a field of knowledge in which a character is involved or a situation of communication. The second group is formed of words used in conjunction with their Germanic counterparts (perspiration – sweat, padre – priest, convivial – friendly) to contrast social position of the characters: literary words serving as social indices of upper class speakers whereas their synonyms of Germanic origin characterize middle or lower class speech portrayals. The third class of words comprises socially marked words (verbs, nouns, and adjectives), or U-words (the term first coined by Allan Ross and Nancy Mitford), the status acquired in the course of social history development (elegant, excellent, sophistication, authoritative, preposterous, etc.). The fourth includes words used in a humorous or ironic meaning to convey the narrator’s attitude to the characters or situation itself (ministrations, histrionic, etc.).

When presented the opportunity, many students have differing opinions and rationales associated with historical events and outcomes. The intent of this paper was to provide students with the economic, social and political dilemmas associated with the autonomy of East Berlin. Students ranked seven possible actions from the most to least acceptable. In addition, students were required to provide both positive and negative factors for each decision and relative ranking. Results from this activity suggested that while most students chose a financial action towards West Berlin, some students had trouble justifying their actions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=content-centered%20learning" title="content-centered learning">content-centered learning</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20war" title=" cold war"> cold war</a>, <a href="https://publications.waset.org/abstracts/search?q=Berlin" title=" Berlin"> Berlin</a>, <a href="https://publications.waset.org/abstracts/search?q=decision-making" title=" decision-making"> decision-making</a> </p> <a href="https://publications.waset.org/abstracts/18348/decision-making-student-empathy-and-cold-war-historical-events-a-case-study-of-abstract-thinking-through-content-centered-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18348.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">455</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> Computational Analysis of Potential Inhibitors Selected Based on Structural Similarity for the Src SH2 Domain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20P.%20Hu">W.

Molecular simulation is a useful tool for developing new drugs and for studying molecular recognition. In this study, we searched potential drug compounds for the inhibition of SH2 domain by performing structural similarity search in PubChem Compound Database. A total of 37 compounds were screened from the database, and then we used the LibDock docking program to evaluate the inhibition effect. The best three compounds (AP22408, CID 71463546 and CID 9917321) were chosen for MD simulations after the LibDock docking. Our results show that the compound CID 9917321 can produce a more stable protein-ligand complex compared to other two currently known inhibitors of Src SH2 domain. The compound CID 9917321 may be useful for the inhibition of SH2 domain based on these computational results. Subsequently experiments are needed to verify the effect of compound CID 9917321 on the SH2 domain in the future studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonpeptide%20inhibitor" title="nonpeptide inhibitor">nonpeptide inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=Src%20SH2%20domain" title=" Src SH2 domain"> Src SH2 domain</a>, <a href="https://publications.waset.org/abstracts/search?q=LibDock" title=" LibDock"> LibDock</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a> </p> <a href="https://publications.waset.org/abstracts/9031/computational-analysis-of-potential-inhibitors-selected-based-on-structural-similarity-for-the-src-sh2-domain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9031.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">269</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> Fault-Detection and Self-Stabilization Protocol for Wireless Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ather%20Saeed">Ather Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Arif%20Khan"> Arif Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Gosper"> Jeffrey Gosper</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sensor devices are prone to errors and sudden node failures, which are difficult to detect in a timely manner when deployed in real-time, hazardous, large-scale harsh environments and in medical emergencies. Therefore, the loss of data can be life-threatening when the sensed phenomenon is not disseminated due to sudden node failure, battery depletion or temporary malfunctioning. We introduce a set of partial differential equations for localizing faults, similar to Green’s and Maxwell’s equations used in Electrostatics and Electromagnetism. We introduce a node organization and clustering scheme for self-stabilizing sensor networks. Green’s theorem is applied to regions where the curve is closed and continuously differentiable to ensure network connectivity. Experimental results show that the proposed GTFD (Green’s Theorem fault-detection and Self-stabilization) protocol not only detects faulty nodes but also accurately generates network stability graphs where urgent intervention is required for dynamically self-stabilizing the network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Green%E2%80%99s%20Theorem" title="Green’s Theorem">Green’s Theorem</a>, <a href="https://publications.waset.org/abstracts/search?q=self-stabilization" title=" self-stabilization"> self-stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=fault-localization" title=" fault-localization"> fault-localization</a>, <a href="https://publications.waset.org/abstracts/search?q=RSSI" title=" RSSI"> RSSI</a>, <a href="https://publications.waset.org/abstracts/search?q=WSN" title=" WSN"> WSN</a>, <a href="https://publications.waset.org/abstracts/search?q=clustering" title=" clustering"> clustering</a> </p> <a href="https://publications.waset.org/abstracts/171016/fault-detection-and-self-stabilization-protocol-for-wireless-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171016.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">75</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> Photocatalytic Packed‐Bed Flow Reactor for Continuous Room‐Temperature Hydrogen Release from Liquid Organic Carriers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malek%20Y.%20S.%20Ibrahim">Malek Y.

In response, a photo flow reactor packed with rhodium (Rh)/titania (TiO2) photocatalyst was reported for the continuous and selective acceptorless dehydrogenation of 1,2,3,4-tetrahydroquinoline to H2 gas and quinoline under visible light irradiation at room temperature. The tradeoff between the reactor pressure drop and its photocatalytic surface area was resolved by selective in-situ photodeposition of Rh in the photo flow reactor post-packing on the outer surface of the TiO2 microparticles available to photon flux, thereby reducing the optimal Rh loading by 10 times compared to a batch reactor, while facilitating catalyst reuse and regeneration. An example of using quinoline as a hydrogen acceptor to lower the energy of the hydrogen production step was demonstrated via the water-gas shift reaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20storage" title="hydrogen storage">hydrogen storage</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20chemistry" title=" flow chemistry"> flow chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20hydrogen" title=" solar hydrogen"> solar hydrogen</a> </p> <a href="https://publications.waset.org/abstracts/154600/photocatalytic-packedbed-flow-reactor-for-continuous-roomtemperature-hydrogen-release-from-liquid-organic-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154600.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">98</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> Experimental Investigation of Proton Exchange Membrane Fuel Cells Operated with Nano Fiber and Nano Fiber/Nano Particle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevser%20Dincer">Kevser Dincer</a>, <a href="https://publications.waset.org/abstracts/search?q=Basma%20Waisi"> Basma Waisi</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Ozan%20Ozdemir"> M.

They can be produced by interfacial polymerization, electrospinning and electrostatic spinning. In this study, behaviours of activated carbon nano fiber (ACNF), carbon nano-fiber (CNF), Polyacrylonitrile/carbon nanotube (PAN/CNT), Polyvinyl alcohol/nano silver (PVA/Ag) in PEM fuel cells are investigated experimentally. This material was used as gas diffusion layer (GDL) in PEM fuel cells. When the performances of these cells are compared to each other at 5x5 cm2 cell, it is found that the PVA/Ag exhibits the best performance among all. In this work, nano fiber and nano fiber/nano particles electrical conductivities have been studied to understand their effects on PEM fuel cell performance. According to the experimental results, the maximum electrical conductivity performance of the fuel cell with nanofiber was found to be at PVA/Ag. The electrical conductivities of CNF, ACNF, PAN/CNT are lower for PEM. The resistance of cell with PVA/Ag is lower than the resistance of cell with PAN/CNT, ACNF, CNF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proton%20exchange%20membrane%20fuel%20cells" title="proton exchange membrane fuel cells">proton exchange membrane fuel cells</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nano%20fiber" title=" carbon nano fiber"> carbon nano fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=activate%20carbon%20nano-fiber" title=" activate carbon nano-fiber"> activate carbon nano-fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=PVA%20fiber" title=" PVA fiber"> PVA fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=PAN%20fiber" title=" PAN fiber"> PAN fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title=" carbon nanotube"> carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20particle%20nanocomposites" title=" nano particle nanocomposites"> nano particle nanocomposites</a> </p> <a href="https://publications.waset.org/abstracts/38111/experimental-investigation-of-proton-exchange-membrane-fuel-cells-operated-with-nano-fiber-and-nano-fibernano-particle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38111.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">391</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">41</span> Comparing the Detection of Autism Spectrum Disorder within Males and Females Using Machine Learning Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Wolff">Joseph Wolff</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Eilbott"> Jeffrey Eilbott</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Autism Spectrum Disorders (ASD) are a spectrum of social disorders characterized by deficits in social communication, verbal ability, and interaction that can vary in severity. In recent years, researchers have used magnetic resonance imaging (MRI) to help detect how neural patterns in individuals with ASD differ from those of neurotypical (NT) controls for classification purposes. This study analyzed the classification of ASD within males and females using functional MRI data. Functional connectivity (FC) correlations among brain regions were used as feature inputs for machine learning algorithms. Analysis was performed on 558 cases from the Autism Brain Imaging Data Exchange (ABIDE) I dataset. When trained specifically on females, the algorithm underperformed in classifying the ASD subset of our testing population. Although the subject size was relatively smaller in the female group, the manual matching of both male and female training groups helps explain the algorithm’s bias, indicating the altered sex abnormalities in functional brain networks compared to typically developing peers. These results highlight the importance of taking sex into account when considering how generalizations of findings on males with ASD apply to females. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism%20spectrum%20disorder" title="autism spectrum disorder">autism spectrum disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroimaging" title=" neuroimaging"> neuroimaging</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20differences" title=" sex differences"> sex differences</a> </p> <a href="https://publications.waset.org/abstracts/139770/comparing-the-detection-of-autism-spectrum-disorder-within-males-and-females-using-machine-learning-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139770.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">209</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> Automatic Adjustment of Thresholds via Closed-Loop Feedback Mechanism for Solder Paste Inspection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Chen%20Wei">Chia-Chen Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Pack%20Hsieh"> Pack Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Chen"> Jeffrey Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Surface Mount Technology (SMT) is widely used in the area of the electronic assembly in which the electronic components are mounted to the surface of the printed circuit board (PCB). Most of the defects in the SMT process are mainly related to the quality of solder paste printing. These defects lead to considerable manufacturing costs in the electronics assembly industry. Therefore, the solder paste inspection (SPI) machine for controlling and monitoring the amount of solder paste printing has become an important part of the production process. So far, the setting of the SPI threshold is based on statistical analysis and experts’ experiences to determine the appropriate threshold settings. Because the production data are not normal distribution and there are various variations in the production processes, defects related to solder paste printing still occur. In order to solve this problem, this paper proposes an online machine learning algorithm, called the automatic threshold adjustment (ATA) algorithm, and closed-loop architecture in the SMT process to determine the best threshold settings. Simulation experiments prove that our proposed threshold settings improve the accuracy from 99.85% to 100%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data%20analytics" title="big data analytics">big data analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=Industry%204.0" title=" Industry 4.0"> Industry 4.0</a>, <a href="https://publications.waset.org/abstracts/search?q=SPI%20threshold%20setting" title=" SPI threshold setting"> SPI threshold setting</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20mount%20technology" title=" surface mount technology"> surface mount technology</a> </p> <a href="https://publications.waset.org/abstracts/114158/automatic-adjustment-of-thresholds-via-closed-loop-feedback-mechanism-for-solder-paste-inspection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114158.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">116</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">39</span> Design and Evaluation of Oven Type Furnace Using Earth Materials for Roasting Foods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Cacho">Jeffrey Cacho</a>, <a href="https://publications.waset.org/abstracts/search?q=Sherwin%20Reyes"> Sherwin Reyes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research targeted enhancing energy utilization and reducing waste in roasting processes, particularly in Camarines Norte, where Bounty Agro Ventures Incorporated dominates through brands such as Chooks-to-Go, Uling Roaster, and Reyal.

A staggering 90% of these businesses use traditional glass-type roasting furnaces fueled by wood charcoal, leading to significant energy loss and inefficiency due to suboptimal heat conservation. Only a mere 10% employ electric ovens. Many available furnaces, typically constructed from industrial materials through welding and other metal joining techniques, are not energy-efficient. Cost-prohibitive commercial options compel some micro-enterprises to fabricate their furnaces. The study proposed developing an eco-friendly, cost-effective roasting furnace with excellent heat retention. The distinct design aimed to reduce cooks' heat exposure and overall fuel consumption. The furnace features an angle bar frame, a combustion chute for fuel burning, a heat-retaining clay-walled chamber, and a top cover, all contributing to improved energy savings and user safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass%20roasting%20furnace" title="biomass roasting furnace">biomass roasting furnace</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20storage" title=" heat storage"> heat storage</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion%20chute" title=" combustion chute"> combustion chute</a>, <a href="https://publications.waset.org/abstracts/search?q=start-up%20roasting%20business" title=" start-up roasting business"> start-up roasting business</a> </p> <a href="https://publications.waset.org/abstracts/185153/design-and-evaluation-of-oven-type-furnace-using-earth-materials-for-roasting-foods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185153.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">53</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> An Investigation of the Barriers to E-Business Implementation in Small and Medium-Sized Enterprises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Chang">Jeffrey Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Barun%20Dasgupta"> Barun Dasgupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> E-business technologies, whereby business transactions are conducted remotely using the Internet, present unique opportunities and challenges for business. E-business technologies are applicable to a wide range of organizations and small and medium-sized enterprises (SMEs) are no exception. There is an established body of literature about e-business, looking at definitions, concepts, benefits and challenges. In general, however, the research focus has been on larger organizations, not SMEs. In an attempt to redress the balance of research, this paper looks at e-business technologies specifically from a small business perspective. It seeks to identify the possible barriers that SMEs might face when considering adoption of the e-business concept and practice as part of their business process change initiatives and implementation. To facilitate analysis of these barriers a conceptual framework has been developed which outlines the key conceptual and practical challenges of e-business implementation in SMEs. This is developed following a literature survey comprised of three categories: characteristics of SMEs, issues of IS/IT use in SMEs and general e-business adoption and implementation issues. The framework is then empirically assessed against 7 SMEs who have yet to implement e-business or whose e-business efforts have been unsatisfactory. Conclusions from the case studies can be used to verify the framework, and set parameters for further larger scale empirical investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20process%20change" title="business process change">business process change</a>, <a href="https://publications.waset.org/abstracts/search?q=disruptive%20technologies" title=" disruptive technologies"> disruptive technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20business%20%28e-Business%29" title=" electronic business (e-Business)"> electronic business (e-Business)</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20commerce%20%28e-Commerce%29" title=" electronic commerce (e-Commerce)"> electronic commerce (e-Commerce)</a>, <a href="https://publications.waset.org/abstracts/search?q=ICT%20adoption" title=" ICT adoption"> ICT adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20and%20medium%20sized%20enterprises%20%28SMEs%29" title=" small and medium sized enterprises (SMEs) "> small and medium sized enterprises (SMEs) </a> </p> <a href="https://publications.waset.org/abstracts/19202/an-investigation-of-the-barriers-to-e-business-implementation-in-small-and-medium-sized-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19202.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">538</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> Investigating the Role of Dystrophin in Neuronal Homeostasis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samantha%20Shallop">Samantha Shallop</a>, <a href="https://publications.waset.org/abstracts/search?q=Hakinya%20Karra"> Hakinya Karra</a>, <a href="https://publications.waset.org/abstracts/search?q=Tytus%20Bernas"> Tytus Bernas</a>, <a href="https://publications.waset.org/abstracts/search?q=Gladys%20Shaw"> Gladys Shaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Gretchen%20Neigh"> Gretchen Neigh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Dupree"> Jeffrey Dupree</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathula%20Thangarajh"> Mathula Thangarajh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abnormal neuronal homeostasis is considered a structural correlate of cognitive deficits in Duchenne Muscular Dystrophy. Neurons are highly polarized cells with multiple dendrites but a single axon. Trafficking of cellular organelles are highly regulated, with the cargo in the somatodendritic region of the neuron not permitted to enter the axonal compartment. We investigated the molecular mechanisms that regular organelle trafficking in neurons using a multimodal approach, including high-resolution structural illumination, proteomics, immunohistochemistry, and computational modeling. We investigated the expression of ankyrin-G, the master regulator controlling neuronal polarity. The expression of ankyrin G and the morphology of the axon initial segment was profoundly abnormal in the CA1 hippocampal neurons in the mdx52 animal model of DMD. Ankyrin-G colocalized with kinesin KIF5a, the anterograde protein transporter, with higher levels in older mdx52 mice than younger mdx52 mice. These results suggest that the functional trafficking from the somatodendritic compartment is abnormal. Our data suggests that dystrophin deficiency compromised neuronal homeostasis via ankyrin-G-based mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurons" title="neurons">neurons</a>, <a href="https://publications.waset.org/abstracts/search?q=axonal%20transport" title=" axonal transport"> axonal transport</a>, <a href="https://publications.waset.org/abstracts/search?q=duchenne%20muscular%20dystrophy" title=" duchenne muscular dystrophy"> duchenne muscular dystrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=organelle%20transport" title=" organelle transport"> organelle transport</a> </p> <a href="https://publications.waset.org/abstracts/156048/investigating-the-role-of-dystrophin-in-neuronal-homeostasis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156048.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">95</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> The Impact of Biodiversity and Urban Ecosystem Services in Real Estate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carmen%20Cantuarias-Villessuzanne">Carmen Cantuarias-Villessuzanne</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Blain"> Jeffrey Blain</a>, <a href="https://publications.waset.org/abstracts/search?q=Radmila%20Pineau"> Radmila Pineau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our research project aims at analyzing the sensitiveness of French households to urban biodiversity and urban ecosystem services (UES). Opinion surveys show that the French population is sensitive to biodiversity and ecosystem services loss, but the value given to these issues within urban fabric and real estate market lacks evidence. Using GIS data and economic evaluation, by hedonic price methods, weassess the isolated contribution of the explanatory variables of biodiversityand UES on the price of residential real estate. We analyze the variation of the valuefor three urban ecosystem services - flood control, proximity to green spaces, and refreshment - on the price of real estate whena property changes ownership. Our modeling and mapping focus on the price at theIRIS scale (statistical information unit) from 2014 to 2019. The main variables are internal characteristics of housing (area, kind of housing, heating), external characteristics(accessibility and infrastructure, economic, social, and physical environmentsuch as air pollution, noise), and biodiversity indicators and urban ecosystemservices for the Ile-de-France region. Moreover, we compare environmental values on the enhancement of greenspaces and their impact on residential choices. These studies are very useful for real estate developers because they enable them to promote green spaces, and municipalities to become more attractive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20ecosystem%20services" title="urban ecosystem services">urban ecosystem services</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20real%20estate" title=" sustainable real estate"> sustainable real estate</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20biodiversity%20perception" title=" urban biodiversity perception"> urban biodiversity perception</a>, <a href="https://publications.waset.org/abstracts/search?q=hedonic%20price" title=" hedonic price"> hedonic price</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20values" title=" environmental values"> environmental values</a> </p> <a href="https://publications.waset.org/abstracts/147354/the-impact-of-biodiversity-and-urban-ecosystem-services-in-real-estate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147354.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">132</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> The Changing Role of the Chief Academic Officer in American Higher Education: Causes and Consequences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20W.%20Markowitz">Michael W.

What was once a domain of competition among prospective students for a limited number of college and university seats has become a marketplace in which institutions vie for the enrollment of educational consumers. A central figure in this paradigm shift has been the Chief Academic Officer (CAO), whose institutional role has also evolved beyond academics to include such disparate responsibilities as strategic planning, fiscal oversight, student recruitment, fundraising and personnel management. This paper explores the scope and impact of this transition by, first, explaining its context: the intersection of key social, economic and political factors in neo-conservative, late 20th Century America that redefined the value and accountability of institutions of higher learning. This context, in turn, is shown to have redefined the role and function of the CAO from a traditional academic leader to one centered on the successful application of corporate principles of organizational and fiscal management. Information gathered from a number of sitting Provosts, Vice-Presidents of Academic Affairs and Deans of Faculty is presented to illustrate the parameters of this change, as well as the extent to which today’s academic officers feel prepared and equipped to fulfill this broader institutional role. The paper concludes with a discussion of the impact of this transition on the American academy and whether it serves as a portend of change to come in higher education systems around the globe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20administration" title="academic administration">academic administration</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20management" title=" organizational management"> organizational management</a> </p> <a href="https://publications.waset.org/abstracts/73786/the-changing-role-of-the-chief-academic-officer-in-american-higher-education-causes-and-consequences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73786.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">220</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> An Assessment of the Anthropometric Characteristics of Malaysian Cricket Batsmen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zia%20ul%20Haq">Muhammad Zia ul Haq</a>, <a href="https://publications.waset.org/abstracts/search?q=Ong%20Kuan%20Boon"> Ong Kuan Boon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Low%20Fook%20Lee"> Jeffrey Low Fook Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Bendri%20Bin%20Dasril"> Bendri Bin Dasril</a>, <a href="https://publications.waset.org/abstracts/search?q=Amna%20Iqbal"> Amna Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saleem"> Muhammad Saleem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is bond of two purpose, first is to establish the anthropometric profile of Malaysian cricket batsmen and second, to find the variances among the anthropometric characteristics of ten under-16 years, eight under-19 years and eight senior teams batsmen. The anthropometric variables were measured as 8 skinfolds, 12 circumferences, 06 lengths and 05 breadths, stature, sitting height, arm span, body mass, hand grip strength and leg strength. The batsmen of under-19 and under-16 found similar in skinfolds, sum of skinfolds, circumferences and breadth measurements but significantly lesser than the senior team batsmen. Senior and Under-19 batsmen were almost found similar in segmental lengths, heights and arm span but significantly higher than the under-16 batsmen. Breadth measurements the under-19 found higher than the senior and u-16 batsmen. The hand grips strength of the senior batsmen significantly high than the uder-19 and under-16 players and both groups were similar and no significant difference were found in leg strength of all three groups batsmen. Leg strength were found significant correlation with wrist, hip, thigh, and calf girth and handgrip strength. The hand grip strength were found correlated with all variables except biceps, mid-thigh skinfold, segmental length, humerus breadth. It is concluded from the present study that the girth segments and hand grip strength are the predictors of good performance in cricket batting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cricket%20batting" title="cricket batting">cricket batting</a>, <a href="https://publications.waset.org/abstracts/search?q=batsmen" title=" batsmen"> batsmen</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropometry" title=" anthropometry"> anthropometry</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20segments" title=" body segments"> body segments</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20grip%20strength" title=" hand grip strength"> hand grip strength</a> </p> <a href="https://publications.waset.org/abstracts/21707/an-assessment-of-the-anthropometric-characteristics-of-malaysian-cricket-batsmen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21707.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">575</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> Innovations in International Trauma Education: An Evaluation of Learning Outcomes and Community Impact of a Guyanese trauma Training Graduate Program</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Ansloos">Jeffrey Ansloos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> International trauma education in low and emerging economies requires innovative methods for capacity building in existing social service infrastructures. This study details the findings of a program evaluation used to assess the learning outcomes and community impact of an international trauma-focused graduate degree program in Guyana. Through a collaborative partnership between Lesley University, the Government of Guyana, and UNICEF, a 2-year low-residency masters degree graduate program in trauma-focused assessment, intervention, and treatment was piloted with a cohort of Guyanese mental health professionals. Through an analytical review of the program development, as well as qualitative data analysis of participant interviews and focus-groups, this study will address the efficacy of the programming in terms of preparedness of professionals to understand, evaluate and implement trauma-informed practices across various child, youth, and family mental health service settings. Strengths and limitations of this international trauma-education delivery model will be discussed with particular emphasis on the role of capacity-building interventions, community-based participatory curriculum development, innovative technological delivery platforms, and interdisciplinary education.

Immune checkpoint immunotherapy (ICI) is commonly used in the clinic to re-activate immune reactions against mutated proteins, called neoantigens, resulting in tumor remission in cancer patients. However, only around 20% of patients show durable response to ICI. While tumor mutational burden (TMB) has been approved by the Food and Drug Administration (FDA) as a criterion for ICI therapy, the relevance of the subcellular localizations of the mutated proteins within the tumor cell has not been investigated. Here, we hypothesized that localization of mutations impacts the effect of immune responsiveness to ICI. We analyzed publicly available tumor mutation sequencing data of ICI treated patients from 3 independent datasets. We extracted the subcellular localization from the UniProtKB/Swiss-Prot database and quantified the proportion of membrane, cytoplasmic, nuclear, or secreted mutations per patient. We analyzed this information in relation to response to ICI treatment and overall survival of patients showing with 1722 ICI-treated patients that high mutational burden localized at the membrane (mTMB), correlate with ICI responsiveness, and improved overall survival in multiple cancer types. We anticipate that our results will ameliorate predictability of cancer patient response to ICI with potential implications in clinical guidelines to tailor ICI treatment. This would not only increase patient survival for those receiving ICI, but also patients’ quality of life by reducing the number of patients enduring non-effective ICI treatments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=immunotherapy" title=" immunotherapy"> immunotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20neoantigens" title=" membrane neoantigens"> membrane neoantigens</a>, <a href="https://publications.waset.org/abstracts/search?q=efficacy%20prediction" title=" efficacy prediction"> efficacy prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a> </p> <a href="https://publications.waset.org/abstracts/155842/membrane-localized-mutations-as-predictors-of-checkpoint-blockade-efficacy-in-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155842.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">109</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> The Role of Phycoremediation in the Sustainable Management of Aquatic Pollution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Ezenweani">Raymond Ezenweani</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Ogbebor"> Jeffrey Ogbebor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The menace of aquatic pollution has become increasingly of great concern and the effects of this pollution as a result of anthropogenic activities cannot be over emphasized. Phycoremediation is the application of algal remediation technology in the removal of harmful products from the environment. Harmful products also known as pollutants are usually introduced into the environment through variety of processes such as industrial discharge, agricultural runoff, flooding, and acid rain. This work has to do with the capability of algae in the efficient removal of different pollutants, ranging from hydrocarbons, eutrophication, agricultural chemicals and wastes, heavy metals, foul smell from septic tanks or dumps through different processes such as bioconversion, biosorption, bioabsorption and biodecomposition. Algae are capable of bioconversion of environmentally persistent compounds to degradable compounds and also capable of putting harmful bacteria growth into check in waste water remediation. Numerous algal organisms such as Nannochloropsis spp, Chlorella spp, Tetraselmis spp, Shpaerocystics spp, cyanobacteria and different macroalgae have been tested by different researchers in laboratory scale and shown to have 100% efficiency in environmental remediation. Algae as a result of their photosynthetic capacity are also efficient in air cleansing and management of global warming by sequestering carbon iv oxide in air and converting it into organic carbon, thereby making food available for the other organisms in the higher trophic level of the aquatic food chain. Algae play major role in the sustenance of the aquatic ecosystem by their virtue of being photosynthetic. They are the primary producers and their role in environmental sustainability is remarkable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algae" title="Algae ">Algae </a>, <a href="https://publications.waset.org/abstracts/search?q=Pollutant" title=" Pollutant"> Pollutant</a>, <a href="https://publications.waset.org/abstracts/search?q=." title=".">.</a>, <a href="https://publications.waset.org/abstracts/search?q=Phycoremediation" title=" Phycoremediation"> Phycoremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=Aquatic" title=" Aquatic"> Aquatic</a>, <a href="https://publications.waset.org/abstracts/search?q=Sustainability" title=" Sustainability"> Sustainability</a> </p> <a href="https://publications.waset.org/abstracts/120451/the-role-of-phycoremediation-in-the-sustainable-management-of-aquatic-pollution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120451.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">126</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> Graphene Based Materials as Novel Membranes for Water Desalination and Boron Separation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Francesca%20Risplendi">Francesca Risplendi</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-Chiang%20Lin"> Li-Chiang Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20C.%20Grossman"> Jeffrey C.

However, the most popular water filtration method available is the reverse osmosis (RO) technique, still suffers from important drawbacks, such as a large energy demands and high process costs. In addition some serious limitations have been recently discovered, among them, the boron problem seems to have a critical meaning. Boron has been found to have a dual effect on the living systems on Earth and the difference between boron deficiency and boron toxicity levels is quite small. The aim of this project is to develop a new generation of RO membranes based on porous graphene or reduced graphene oxide (rGO) able to remove salts from seawater and to reduce boron concentrations in the permeate to the level that meets the drinking or process water requirements, by means of a theoretical approach based on density functional theory and classical molecular dynamics. Computer simulations have been employed to investigate the relationship between the atomic structure of nanoporous graphene or rGO monolayer and its membrane properties in RO applications (i.e. water permeability and resilience at RO pressures). In addition, an emphasis has been given to multilayer nanoporous rGO and rGO flakes based membranes. By means of non-equilibrium MD simulations, we investigated the water transport mechanism permeating through such multilayer membrane focusing on the effect of slit widths and sheet geometries. These simulations allowed us to establish the implications of these graphene based materials as promising membrane properties for desalination plants and as boron filtration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boron%20filtration" title="boron filtration">boron filtration</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20membrane" title=" graphene membrane"> graphene membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=reduced%20graphene%20oxide%20membrane" title=" reduced graphene oxide membrane"> reduced graphene oxide membrane</a> </p> <a href="https://publications.waset.org/abstracts/69154/graphene-based-materials-as-novel-membranes-for-water-desalination-and-boron-separation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69154.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">299</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> Body-Worn Camera Use in the Emergency Department: Patient and Provider Satisfaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Ho">Jeffrey Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Scott%20Joing"> Scott Joing</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Nystrom"> Paul Nystrom</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Heegaard"> William Heegaard</a>, <a href="https://publications.waset.org/abstracts/search?q=Danielle%20Hart"> Danielle Hart</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Plummer"> David Plummer</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Miner"> James Miner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Body-Worn Cameras (BWCs) are used in public safety to record encounters. They are shown to enhance the accuracy of documentation in virtually every situation. They are not widely used in medical encounters in part because of concern for patient acceptance. The goal of this pilot study was to determine if BWC use is acceptable to the patient. This was a prospective, observational study of the AXON Flex BWC (TASER International, Scottsdale, AZ) conducted at an urban, Level 1 Trauma Center Emergency Department (ED). The BWC was worn by Emergency Physicians (EPs) on their shifts during a 30-day period. The BWC was worn at eye-level mounted on a pair of clear safety glasses. Patients seen by the EP were enrolled in the study by a trained research associate. Patients who were <18 years old, who were with other people in the exam room, did not speak English, were critically ill, had chief complaints involving genitalia or sexual assault, were considered to be vulnerable adults, or with an altered mental status were excluded. Consented patients were given a survey after the encounter to determine their perception of the BWC. The questions asked involved the patients’ perceptions of a BWC being present during their interaction with their EP. Data were analyzed with descriptive statistics. There were 417 patients enrolled in the study. 3/417 (0.7%) patients were intimidated by the BWC, 1/417 (0.2%) was nervous because of the BWC, 0/417 (0%) were inhibited from telling the EP certain things because of the BWC, 57/417 (13.7%) patients did not notice the device, and 305/417 (73.1%) patients were had a favorable perception about the BWC being used during their encounter. The use of BWCs appears feasible in the ED, with largely favorable perceptions and acceptance of the device by the patients. Further study is needed to determine the best use and practices of BWCs during ED patient encounters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body-worn%20camera" title="body-worn camera">body-worn camera</a>, <a href="https://publications.waset.org/abstracts/search?q=documentation" title=" documentation"> documentation</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20satisfaction" title=" patient satisfaction"> patient satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=video" title=" video"> video</a> </p> <a href="https://publications.waset.org/abstracts/57078/body-worn-camera-use-in-the-emergency-department-patient-and-provider-satisfaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57078.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">373</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> Solvent-Aided Dispersion of Tannic Acid to Enhance Flame Retardancy of Epoxy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Korey">Matthew Korey</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Youngblood"> Jeffrey Youngblood</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Howarter"> John Howarter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Significance: Tannic acid (TA) is a bio-based high molecular weight organic, aromatic molecule that has been found to increase thermal stability and flame retardancy of many polymer matrices when used as an additive. Although it is biologically sourced, TA is a pollutant in industrial wastewater streams, and there is a desire to find applications in which to downcycle this molecule after extraction from these streams. Additionally, epoxy thermosets have revolutionized many industries, but are too flammable to be used in many applications without additives which augment their flame retardancy (FR). Many flame retardants used in epoxy thermosets are synthesized from petroleum-based monomers leading to significant environmental impacts on the industrial scale. Many of these compounds also have significant impacts on human health. Various bio-based modifiers have been developed to improve the FR of the epoxy resin; however, increasing FR of the system without tradeoffs with other properties has proven challenging, especially for TA. Methodologies: In this work, TA was incorporated into the thermoset by use of solvent-exchange using methyl ethyl ketone, a co-solvent for TA, and epoxy resin. Samples were then characterized optically (UV-vis spectroscopy and optical microscopy), thermally (thermogravimetric analysis and differential scanning calorimetry), and for their flame retardancy (mass loss calorimetry). Major Findings: Compared to control samples, all samples were found to have increased thermal stability. Further, the addition of tannic acid to the polymer matrix by the use of solvent greatly increased the compatibility of the additive in epoxy thermosets. By using solvent-exchange, the highest loading level of TA found in literature was achieved in this work (40 wt%). Conclusions: The use of solvent-exchange shows promises for circumventing the limitations of TA in epoxy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable" title="sustainable">sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20retardant" title=" flame retardant"> flame retardant</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy" title=" epoxy"> epoxy</a>, <a href="https://publications.waset.org/abstracts/search?q=tannic%20acid" title=" tannic acid"> tannic acid</a> </p> <a href="https://publications.waset.org/abstracts/116586/solvent-aided-dispersion-of-tannic-acid-to-enhance-flame-retardancy-of-epoxy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116586.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">130</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> The Cost-Effectiveness of High-Volume Hospital’s Surgical Care for Pancreatic Cancer: Economic Evidence Reviewed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shannon%20Hearney">Shannon Hearney</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Hoch"> Jeffrey Hoch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pancreatic cancer is a notoriously costly and deadly form of cancer. Many types of treatment centers exist for patients to seek care from, including high-volume centers which have shown promise to provide the highest quality of care. While it may be true that this type of center provides the best care it is unclear if that care is cost-effective. Studies in the US have confirmed that high-volume hospitals do provide higher quality of care but have shown inconsistencies in the cost-effectiveness of that care. Other studies, like those from Finland have shown that high-volume centers had lower mortality and lower costs than low-volume centers. This paper thus seeks to review the current scientific literature to better understand if high-volume centers are cost-effective in delivering care in both a European setting and in the US. A review of major reference databases such as Medline, Embase and PubMed will be conducted for cost-effectiveness studies on the surgical treatment of pancreatic cancer at high-volume centers. Possible MeSH terms to be included, but not limited to, are: “pancreatic cancer”, “cost analysis”, “cost-effectiveness”, “economic evaluation”, “pancreatic neoplasms”, “surgical”, and “high-volume”. Studies must also have been available in the English language. This review will encompass European scientific literature, as well as those in the US. Based on our preliminary findings, we anticipate high-volume hospitals to provide better care at greater costs. We anticipate that high-volume hospitals may be cost-effective in different contexts depending on the national structure of a healthcare system. Countries with more centralized and socialized healthcare may yield results that are more cost-effective. High-volume centers may differ in their cost-effectiveness of the surgical care of pancreatic cancer internationally especially when comparing those in the United States to others throughout Europe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost-effectiveness%20analysis" title="cost-effectiveness analysis">cost-effectiveness analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20evaluation" title=" economic evaluation"> economic evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=pancreatic%20cancer" title=" pancreatic cancer"> pancreatic cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=scientific%20literature%20review" title=" scientific literature review"> scientific literature review</a> </p> <a href="https://publications.waset.org/abstracts/153122/the-cost-effectiveness-of-high-volume-hospitals-surgical-care-for-pancreatic-cancer-economic-evidence-reviewed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153122.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">90</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> Four-Way Coupled CFD-Dem Simulation of Concrete Pipe Flow Using a Non-Newtonian Rheological Model: Investigating the Simulation of Lubrication Layer Formation and Plug Flow Zones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tooran%20Tavangar">Tooran Tavangar</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Hosseinpoor"> Masoud Hosseinpoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20S.%20Marshall"> Jeffrey S.

Fresh concrete, characterized as a biphasic suspension, features aggregates comprising the solid-suspended phase with diverse particle-size distributions (PSD) within a non-Newtonian cement paste/mortar matrix forming the liquid phase. The fluid phase was simulated using CFD, while the aggregates were modeled using DEM. Interaction forces between the fluid and solid particles were considered through CFD-DEM computations. To capture the viscoelastic characteristics of the suspending fluid, a bi-viscous approach was adopted, incorporating a critical shear rate proportional to the yield stress of the mortar. In total, three diphasic suspensions were simulated, each featuring distinct particle size distributions and a concentration of 10% for five subclasses of spherical particles ranging from 1 to 17 mm in a suspending fluid. The adopted bi-viscous approach successfully simulated both un-sheared (plug flow) and sheared zones. Furthermore, shear-induced particle migration (SIPM) was assessed by examining coefficients of variation in particle concentration across the pipe. These SIPM values were then compared with results obtained using CFD-DEM under the Newtonian assumption. The study highlighted the crucial role of yield stress in the mortar phase, revealing that lower yield stress values can lead to increased flow rates and higher SIPM across the pipe. <p
