Nevertheless, because of their non-renewable energy sources and the contribution of ecologically unfriendly working fluids, these units are a major source of CO2 emissions in these countries. The utilisation of sustainable technologies nowadays is essential to reduce the adverse effects of CO2 emissions by replacing conventional technologies. This paper investigates the feasibility of running an off-grid solar-powered air-conditioning bed unit using three low GWP refrigerants (R32, R290, and R600a) to supersede conventional refrigerants.A prototype air conditioning unit was built to supply cold air to a canopy that was connected to it. The assembled unit was designed to distribute cold air to a canopy connected to it. This system is powered by two 400 W photovoltaic panels, with battery storage supplying power to the unit at night-time. Engineering Equation Solver (EES) software is used to mathematically model the vapor compression cycle (VCC) and predict the unit's energetic and exergetic performance. The TRNSYS software was used to simulate the electricity storage performance of the batteries, whereas the IES-VE was used to determine the amount of solar energy required to power the unit. The article provides an analytical design guideline, as well as a comprehensible process system. Combining a renewable energy source to power an AC based-VCC provides an excellent solution to the real problems of high-energy consumption in warm-climate countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air-conditioning" title="air-conditioning">air-conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=refrigerants" title=" refrigerants"> refrigerants</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20panel" title=" PV panel"> PV panel</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storages" title=" energy storages"> energy storages</a>, <a href="https://publications.waset.org/abstracts/search?q=VCC" title=" VCC"> VCC</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy" title=" exergy"> exergy</a> </p> <a href="https://publications.waset.org/abstracts/146652/a-theoretical-and-experimental-evaluation-of-a-solar-powered-off-grid-air-conditioning-system-for-residential-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146652.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">175</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">66</span> Thermodynamics Analysis of Transcritical HTHP Cycles Using Eco-Friendly Refrigerant and low-Grade Waste Heat Recovery: A Theoretical Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Y.%20Sulaiman">Adam Y.

Industrial processes including drying, distillation, and injection molding require a process heat exceeding 180°C, rendering the subcriticalHigh-Temperature heat pump(HTHP) technique unsuitable. A transcritical HTHP utilizing ecologically friendly working fluids is a highly recommended system that incorporates the features of high-energy efficiency, extended operational range, and decarbonizing the industrial sector. This paper delves into the possibility and feasibility of leveraging the HTTP system to provide up to 200°C of heat using R1233zd(E) as a working fluid. Using a steady-state model, various transcritical HTHP cycle configurations aretheoretically compared,analyzed, and evaluatedin this study. The heat transfer characteristics for the evaporator and gas cooler are investigated, as well as the cycle's energy, exergetic, and environmental performance. Using the LMTD method, the gas cooler's heat transfer coefficient, overall length, and heat transfer area were calculated. The findings indicate that the heat sink pressure level, as well as the waste heat temperature provided to the evaporator, have a significant impact on overall cycle performance. The investigation revealed the potential challenges and barriers, including the length of the gas cooler and the lubrication of the compression process. The basic transcritical HTTP cycle with additional IHX was demonstrated to be the most efficient cycle across a variety of heat source temperatures ranging from 70 to 90 °C based on theoretical energetic and exergetic performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-temperature%20heat%20pump" title="high-temperature heat pump">high-temperature heat pump</a>, <a href="https://publications.waset.org/abstracts/search?q=transcritical%20cycle" title=" transcritical cycle"> transcritical cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=refrigerants" title=" refrigerants"> refrigerants</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20cooler" title=" gas cooler"> gas cooler</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy" title=" exergy"> exergy</a> </p> <a href="https://publications.waset.org/abstracts/146603/thermodynamics-analysis-of-transcritical-hthp-cycles-using-eco-friendly-refrigerant-and-low-grade-waste-heat-recovery-a-theoretical-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146603.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">163</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">65</span> Theoretical Evaluation of Minimum Superheat, Energy and Exergy in a High-Temperature Heat Pump System Operating with Low GWP Refrigerants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Y.%20Sulaiman">Adam Y.

Hewitt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Suitable low global warming potential (GWP) refrigerants that conform to F-gas regulations are required to extend the operational envelope of high-temperature heat pumps (HTHPs) used for industrial waste heat recovery processes. The thermophysical properties and characteristics of these working fluids need to be assessed to provide a comprehensive understanding of operational effectiveness in HTHP applications. This paper presents the results of a theoretical simulation to investigate a range of low-GWP refrigerants and their suitability to supersede refrigerants HFC-245fa and HFC-365mfc. A steady-state thermodynamic model of a single-stage HTHP with an internal heat exchanger (IHX) was developed to assess system cycle characteristics at temperature ranges between 50 to 80 °C heat source and 90 to 150 °C heat sink. A practical approach to maximize the operational efficiency was examined to determine the effects of regulating minimum superheat within the process and subsequent influence on energetic and exergetic efficiencies. A comprehensive map of minimum superheat across the HTHP operating variables were used to assess specific tipping points in performance at 30 and 70 K temperature lifts. Based on initial results, the refrigerants HCFO-1233zd(E) and HFO-1336mzz(Z) were found to be closely aligned matches for refrigerants HFC-245fa and HFC-365mfc. The overall results show effective performance for HCFO-1233zd(E) occurs between 5-7 K minimum superheat, and HFO-1336mzz(Z) between 18-21 K dependant on temperature lift. This work provides a method to optimize refrigerant selection based on operational indicators to maximize overall HTHPs system performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-temperature%20heat%20pump" title="high-temperature heat pump">high-temperature heat pump</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20superheat" title=" minimum superheat"> minimum superheat</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20%26%20exergy%20efficiency" title=" energy & exergy efficiency"> energy & exergy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20GWP%20refrigerants" title=" low GWP refrigerants"> low GWP refrigerants</a> </p> <a href="https://publications.waset.org/abstracts/145462/theoretical-evaluation-of-minimum-superheat-energy-and-exergy-in-a-high-temperature-heat-pump-system-operating-with-low-gwp-refrigerants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145462.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">185</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">64</span> The Ongoing Impact of Secondary Stressors on Businesses in Northern Ireland Affected by Flood Events</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jill%20Stephenson">Jill Stephenson</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Vaganay"> Marie Vaganay</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Cameron"> Robert Cameron</a>, <a href="https://publications.waset.org/abstracts/search?q=Caoimhe%20McGurk"> Caoimhe McGurk</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Hewitt"> Neil Hewitt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: The key aim of the research was to identify the secondary stressors experienced by businesses affected by single or repeated flooding and to determine to what extent businesses were affected by these stressors, along with any resulting impact on health. Additionally, the research aimed to establish the likelihood of businesses being re-exposed to the secondary stressors through assessing awareness of flood risk, implementation of property protection measures and level of community resilience. Design/methodology/approach: The chosen research method involved the distribution of a questionnaire survey to businesses affected by either single or repeated flood events. The questionnaire included the Impact of Event Scale (a 15-item self-report measure which assesses subjective distress caused by traumatic events). Findings: 55 completed questionnaires were returned by flood impacted businesses. 89% of the businesses had sustained internal flooding while 11% had experienced external flooding. The results established that the key secondary stressors experienced by businesses, in order of priority, were: flood damage, fear of reoccurring flooding, prevention of access to the premise/closure, loss of income, repair works, length of closure and insurance issues. There was a lack of preparedness for potential future floods and consequent vulnerability to the emergence of secondary stressors among flood affected businesses, as flood resistance or flood resilience measures had only been implemented by 11% and 13% respectively. In relation to the psychological repercussions, the Impact of Event scores suggested that potential prevalence of post-traumatic stress disorder (PTSD) was noted among 8 out of 55 respondents (l5%). Originality/value: The results improve understanding of the enduring repercussions of flood events on businesses, indicating that not only residents may be susceptible to the detrimental health impacts of flood events and single flood events may be just as likely as reoccurring flooding to contribute to ongoing stress. Lack of financial resources is a possible explanation for the lack of implementation of property protection measures among businesses, despite 49% experiencing flooding on multiple occasions. Therefore it is recommended that policymakers should consider potential sources of financial support or grants towards flood defences for flood impacted businesses. Any form of assistance should be made available to businesses at the earliest opportunity as there was no significant association between the time of the last flood event and the likelihood of experiencing PTSD symptoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flood%20event" title="flood event">flood event</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20resilience" title=" flood resilience"> flood resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20resistance" title=" flood resistance"> flood resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=PTSD" title=" PTSD"> PTSD</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20stressors" title=" secondary stressors"> secondary stressors</a> </p> <a href="https://publications.waset.org/abstracts/35138/the-ongoing-impact-of-secondary-stressors-on-businesses-in-northern-ireland-affected-by-flood-events" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35138.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Ambivalence in Embracing Artificial Intelligence in the Units of a Public Hospital in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanele%20E.%20Nene%20L.">Sanele E.

Here, the O.MG Cable, an apparently harmless mobile device charger, is used in an unauthorized way to alter the content of a file (accounts record-January_Contributions.xlsx). The aim is to determine if a forensics analyst can reliably determine who has altered the target file; the O.MG Cable or the user of the machine. This work highlights some of the traces of the O.MG Cable left behind on the target computer itself, such as the Product ID (PID) and Vendor ID (ID). Also discussed is the O.MG Cable’s behavior during the experiments. We determine if a forensics analyst could identify if any evidence has been left behind by the programmable device on the target file once it has been removed from the computer to establish if the analyst would be able to link the traces left by the O.MG Cable to the file tampering. It was discovered that the forensic analyst might mistake the actions of the O.MG Cable for the computer users. Experiments carried out in this work could further the discussion as to whether an innocent user could be punished for the unauthorized changes made by a programmable device. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.MG%20cable" title="O.MG cable">O.MG cable</a>, <a href="https://publications.waset.org/abstracts/search?q=programmable%20USB" title=" programmable USB"> programmable USB</a>, <a href="https://publications.waset.org/abstracts/search?q=file%20tampering%20attack" title=" file tampering attack"> file tampering attack</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20evidence%20credibility" title=" digital evidence credibility"> digital evidence credibility</a>, <a href="https://publications.waset.org/abstracts/search?q=miscarriage%20of%20justice" title=" miscarriage of justice"> miscarriage of justice</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20fraud" title=" cyber fraud"> cyber fraud</a> </p> <a href="https://publications.waset.org/abstracts/143005/omg-its-a-cyber-enabled-fraud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143005.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">159</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">61</span> Generator Subgraphs of the Wheel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neil%20M.%20Mame">Neil M.

The edge space of G, denoted by ε(G), is a vector space over the field Z2. The elements of ε(G) are all the subsets of E(G). Vector addition is defined as X+Y = X Δ Y, the symmetric difference of sets X and Y, for X, Y ∈ ε(G). Scalar multiplication is defined as 1.X =X and 0.X = Ø for X ∈ ε(G). The set S ⊆ ε(G) is called a generating set if every element ε(G) is a linear combination of the elements of S. For a non-empty set X ∈ ε(G), the smallest subgraph with edge set X is called edge-induced subgraph of G, denoted by G[X]. The set EH(G) = { A ∈ ε(G) : G[A] ≅ H } denotes the uniform set of H with respect to G and εH(G) denotes the subspace of ε(G) generated by EH(G). If εH(G) is generating set, then we call H a generator subgraph of G. This paper gives the characterization for the generator subgraphs of the wheel that contain cycles and gives the necessary conditions for the acyclic generator subgraphs of the wheel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=edge%20space" title="edge space">edge space</a>, <a href="https://publications.waset.org/abstracts/search?q=edge-induced%20subgraph" title=" edge-induced subgraph"> edge-induced subgraph</a>, <a href="https://publications.waset.org/abstracts/search?q=generator%20subgraph" title=" generator subgraph"> generator subgraph</a>, <a href="https://publications.waset.org/abstracts/search?q=wheel" title=" wheel"> wheel</a> </p> <a href="https://publications.waset.org/abstracts/28953/generator-subgraphs-of-the-wheel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28953.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">464</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">60</span> The Impact of Usefulness and Ease of Using Mobile Learning Technology on Faculty Acceptance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leena%20Ahmad%20Khaleel%20Alfarani">Leena Ahmad Khaleel Alfarani</a>, <a href="https://publications.waset.org/abstracts/search?q=Maggie%20McPherson"> Maggie McPherson</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Morris"> Neil Morris</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the last decade, m-learning has been widely accepted and utilized by many western universities. However, Saudi universities face many challenges in utilizing such technology, a central one being to encourage teachers to use such technology. Although there are several factors that affect faculty members’ participation in the adoption of m-learning, this paper focuses merely on two factors, the usefulness and ease of using m-learning. A sample of 279 faculty members in one Saudi university has responded to the online survey. The results of the study have revealed that there is a statistically significant relationship (at the 0.05 level) between both usefulness and ease of using m-learning factors and the intention of teachers to use m-learning currently and in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20learning" title="mobile learning">mobile learning</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20of%20innovation%20theory" title=" diffusion of innovation theory"> diffusion of innovation theory</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20acceptance" title=" technology acceptance"> technology acceptance</a>, <a href="https://publications.waset.org/abstracts/search?q=faculty%20adoption" title=" faculty adoption"> faculty adoption</a> </p> <a href="https://publications.waset.org/abstracts/33023/the-impact-of-usefulness-and-ease-of-using-mobile-learning-technology-on-faculty-acceptance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33023.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">59</span> Rodriguez Diego, Del Valle Martin, Hargreaves Matias, Riveros Jose Luis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nathainail%20Bashir">Nathainail Bashir</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Anderson"> Neil Anderson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study site was to investigate the current state of the practice with regards to karst detection methods and recommend the best method and pattern of arrays to acquire the desire results.

Two geophysical techniques were employed: multichannel analysis of surface waves (MASW) and electric resistivity tomography (ERT).The MASW data was acquired at each test location using different array lengths and different array orientations (to increase the probability of getting interpretable data in karst terrain). The ERT data were acquired using a dipole-dipole array consisting of 168 electrodes. The MASW data was interpreted (re: estimated depth to physical top of rock) and used to constrain and verify the interpretation of the ERT data. The ERT data indicates poorer quality MASW data were acquired in areas where there was significant local variation in the depth to top of rock. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dipole-dipole" title="dipole-dipole">dipole-dipole</a>, <a href="https://publications.waset.org/abstracts/search?q=ERT" title=" ERT"> ERT</a>, <a href="https://publications.waset.org/abstracts/search?q=Karst%20terrains" title=" Karst terrains"> Karst terrains</a>, <a href="https://publications.waset.org/abstracts/search?q=MASW" title=" MASW "> MASW </a> </p> <a href="https://publications.waset.org/abstracts/58233/rodriguez-diego-del-valle-martin-hargreaves-matias-riveros-jose-luis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58233.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">315</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">58</span> Identity-Based Encryption: A Comparison of Leading Classical and Post-Quantum Implementations in an Enterprise Setting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emily%20Stamm">Emily Stamm</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Smyth"> Neil Smyth</a>, <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20O%27Sullivan"> Elizabeth O'Sullivan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Identity-Based Encryption (IBE), an identity, such as a username, email address, or domain name, acts as the public key. IBE consolidates the PKI by eliminating the repetitive process of requesting public keys for each message encryption. Two of the most popular schemes are Sakai-Kasahara (SAKKE), which is based on elliptic curve pairings, and the Ducas, Lyubashevsky, and Prest lattice scheme (DLP- Lattice), which is based on quantum-secure lattice cryptography. In or- der to embed the schemes in a standard enterprise setting, both schemes are implemented as shared system libraries and integrated into a REST service that functions at the enterprise level. The performance of both schemes as libraries and services is compared, and the practicalities of implementation and application are discussed. Our performance results indicate that although SAKKE has the smaller key and ciphertext sizes, DLP-Lattice is significantly faster overall and we recommend it for most enterprise use cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=identity-based%20encryption" title="identity-based encryption">identity-based encryption</a>, <a href="https://publications.waset.org/abstracts/search?q=post-quantum%20cryptography" title=" post-quantum cryptography"> post-quantum cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=lattice-based%20cryptography" title=" lattice-based cryptography"> lattice-based cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=IBE" title=" IBE"> IBE</a> </p> <a href="https://publications.waset.org/abstracts/146066/identity-based-encryption-a-comparison-of-leading-classical-and-post-quantum-implementations-in-an-enterprise-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146066.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">136</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">57</span> Analysis of the Transcriptional Response of Rhazia stricta to Jasmonic Acid Induction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nahid%20H.%20Hajrah">Nahid H.

It Is involved in fertility, ripening, and sex determination as well as in response to environmental stresses such as herbivory, pathogen drought or temperature shock. Essentially the jasmonic pathway acts to shut down growth in order to induce defence pathways. These pathways include the production of secondary metabolites which have evolved to defend against herbivores and pathogens but are of increasing interest due to their roll in medicine and biotechnology. Here we describe the transcriptional response of Rhazia stricta (a poisonous shrub widely used in traditional medicine) to jasmonic acid, in order to better characterize the genes involved in secondary metabolite production and its response to stress. We observe coordinated upregulation of flavonoid biosynthesis pathway leading to flavonols, flavones and anthocyanins but no similar coordination of the monoterpene indole alkaloid pathway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title="medicinal plants">medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=Rhazia%20stricta" title=" Rhazia stricta"> Rhazia stricta</a>, <a href="https://publications.waset.org/abstracts/search?q=jasmonic%20acid" title=" jasmonic acid"> jasmonic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=transcriptional%20analysis" title=" transcriptional analysis"> transcriptional analysis</a> </p> <a href="https://publications.waset.org/abstracts/107330/analysis-of-the-transcriptional-response-of-rhazia-stricta-to-jasmonic-acid-induction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107330.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">143</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">56</span> The Relationship among EFL Learners’ Creativity, Emotional Intelligence and Self-Efficacy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behdoukht%20Mall%20Amiri">Behdoukht Mall Amiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohreh%20Gheydar"> Zohreh Gheydar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The thrust of the current study was to investigate the relationship among EFL learners' creativity (CR), emotional intelligence (EI), and self-efficacy (SE). To this end, a group of 120 male and female learners, between the ages of 19 and 35 studying BA in English Translation and MA in Teaching English at Islamic Azad University, Central Tehran were selected using convenient sampling and were given three questionnaires: Bar-On’s EQ-I questionnaire by Bar-On (1997), the General Self-Efficacy Scale questionnaire (SGSES) by Sherer et al. (1982), and a questionnaire of creativity (CR) by O'Neil, Abedi, and Spielberger (1992). Analysis of the results through Pearson Moment Correlation Coefficient showed that there was not a significant relationship between students’ CR and EI, and EI and SE. In addition, CR and SE were correlated significantly but negatively. Multiple regressions revealed that CR could significantly predict SE. Regarding the findings of the study, the obtained results may help EFL teachers, teacher trainers, materials developers, and educational policy makers to possess a broader perspective and heightened degree knowledge toward the TEFL practice and to take practical steps toward the attainments of the desired objectives of the profession. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creativity" title="creativity">creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title=" emotional intelligence"> emotional intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=self-efficacy" title=" self-efficacy"> self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a> </p> <a href="https://publications.waset.org/abstracts/7647/the-relationship-among-efl-learners-creativity-emotional-intelligence-and-self-efficacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7647.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">448</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">55</span> Hospitality Genealogy: Tracing the Ethics and Ontologies of Hospitality-Making on the Silk-Routes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neil%20Michael%20Walsh">Neil Michael Walsh</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelique%20Lombarts"> Angelique Lombarts</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The authors propose that hospitality is ‘made’ (constituted and performed) in the encounters on the Silk-Routes. Inspired with an initial Derridean perspective on hospitality (the conditional/unconditional) and methodologically underpinned with a Delueuzian relational-rhizomatic approach, the authors contend that hospitality is (re)produced in the encounters of self/other, east/west (among others). Thus, in the spirit of performativity and using the temporal-spatial conduit of the Silk Routes (the sites of ethical, cultural, economic, and material interaction of such exchange), the authors concur that hospitality is produced at the moment in which it is performed. Key themes engaged as units of analysis become welcome, reception, hostility, (and so on) which the authors engage and examine –as they unfold- in the narratives and accounts and material legacies of those who travelled the Silk Routes between the 2nd and 18th Centuries. The preliminary results suggest that these earlier performative moments in hospitality-making on the silk routes continue to resonate and ‘form’ the hospitalities of today. Indeed, these acts of hospitality continue to reconstitute and are never a final state of affairs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hospitality-genealogy" title="hospitality-genealogy">hospitality-genealogy</a>, <a href="https://publications.waset.org/abstracts/search?q=interactions" title=" interactions"> interactions</a>, <a href="https://publications.waset.org/abstracts/search?q=hospitality-making" title=" hospitality-making"> hospitality-making</a>, <a href="https://publications.waset.org/abstracts/search?q=Silk-Routes" title=" Silk-Routes"> Silk-Routes</a>, <a href="https://publications.waset.org/abstracts/search?q=rhizome" title=" rhizome"> rhizome</a>, <a href="https://publications.waset.org/abstracts/search?q=relationality" title=" relationality"> relationality</a> </p> <a href="https://publications.waset.org/abstracts/129847/hospitality-genealogy-tracing-the-ethics-and-ontologies-of-hospitality-making-on-the-silk-routes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129847.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">134</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">54</span> Threshold Concepts in TESOL: A Thematic Analysis of Disciplinary Guiding Principles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neil%20Morgan">Neil Morgan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The notion of Threshold Concepts has offered a fertile new perspective on the transformative effects of mastery of particular concepts on student understanding of subject matter and their developing identities as inductees into disciplinary discourse communities. Only by successfully traversing key knowledge thresholds, it is claimed, can neophytes gain access to the more sophisticated understandings of subject matter possessed by mature members of a discipline. This paper uses thematic analysis of disciplinary guiding principles to identify nine candidate Threshold Concepts that appear to underpin effective TESOL practice. The relationship between these candidate TESOL Threshold Concepts, TESOL principles, and TESOL instructional techniques appears to be amenable to a schematic representation based on superordinate categories of TESOL practitioner concern and, as such, offers an alternative to the view of Threshold Concepts as a privileged subset of disciplinary core concepts. The paper concludes by exploring the potential of a Threshold Concepts framework to productively inform TESOL initial teacher education (ITE) and in-service education and training (INSET). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TESOL" title="TESOL">TESOL</a>, <a href="https://publications.waset.org/abstracts/search?q=threshold%20concepts" title=" threshold concepts"> threshold concepts</a>, <a href="https://publications.waset.org/abstracts/search?q=TESOL%20principles" title=" TESOL principles"> TESOL principles</a>, <a href="https://publications.waset.org/abstracts/search?q=TESOL%20ITE%2FINSET" title=" TESOL ITE/INSET"> TESOL ITE/INSET</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20of%20practice" title=" community of practice"> community of practice</a> </p> <a href="https://publications.waset.org/abstracts/127795/threshold-concepts-in-tesol-a-thematic-analysis-of-disciplinary-guiding-principles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> More Precise: Patient-Reported Outcomes after Stroke</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amber%20Elyse%20Corrigan">Amber Elyse Corrigan</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Smith"> Alexander Smith</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20Pennington"> Anna Pennington</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Carter"> Ben Carter</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Hewitt"> Jonathan Hewitt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Purpose: Morbidity secondary to stroke is highly heterogeneous, but it is important to both patients and clinicians in post-stroke management and adjustment to life after stroke. The consideration of post-stroke morbidity clinically and from the patient perspective has been poorly measured. The patient-reported outcome measures (PROs) in morbidity assessment help improve this knowledge gap. The primary aim of this study was to consider the association between PRO outcomes and stroke predictors. Methods: A multicenter prospective cohort study assessed 549 stroke patients at 19 hospital sites across England and Wales during 2019. Following a stroke event, demographic, clinical, and PRO measures were collected. Prevalence of morbidity within PRO measures was calculated with associated 95% confidence intervals. Predictors of domain outcome were calculated using a multilevel generalized linear model. Associated P -values and 95% confidence intervals are reported. Results: Data were collected from 549 participants, 317 men (57.7%) and 232 women (42.3%) with ages ranging from 25 to 97 (mean 72.7). PRO morbidity was high post-stroke; 93.2% of the cohort report post-stroke PRO morbidity. Previous stroke, diabetes, and gender are associated with worse patient-reported outcomes across both the physical and cognitive domains. Conclusions: This large-scale multicenter cohort study illustrates the high proportion of morbidity in PRO measures. Further, we demonstrate key predictors of adverse outcomes (Diabetes, previous stroke, and gender) congruence with clinical predictors. The PRO has been demonstrated to be an informative and useful stroke when considering patient-reported outcomes and has wider implications for considerations of PROs in clinical management. Future longitudinal follow-up with PROs is needed to consider association of long-term morbidity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=morbidity" title="morbidity">morbidity</a>, <a href="https://publications.waset.org/abstracts/search?q=patient-reported%20outcome" title=" patient-reported outcome"> patient-reported outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=PRO" title=" PRO"> PRO</a>, <a href="https://publications.waset.org/abstracts/search?q=stroke" title=" stroke"> stroke</a> </p> <a href="https://publications.waset.org/abstracts/134965/more-precise-patient-reported-outcomes-after-stroke" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134965.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">131</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">52</span> Application of Failure Mode and Effects Analysis (FMEA) on the Virtual Process Hazard Analysis of Acetone Production Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Princes%20Ann%20E.%20Prieto">Princes Ann E.

The study is done on the important matching parameters such as like wire diameter and helix to the ground plane gap. It is intended that these parameters control the matching without detrimentally affecting the radiation pattern. Using transmission line theory, a simple broadband technique is proposed, which is applicable for perfect matching of antennas with similar design parameters. We provide design curves to help to choose the proper dimensions of the matching section based on the antenna’s unmatched input impedance. Finally, using the proposed technique, a 4-turn axial mode helix is designed at 2.5 GHz center frequency and the measurement results of the manufactured antenna will be included. This parametric study gives a good insight into the input impedance characteristics of axial mode helical antennas and the proposed impedance matching approach provides a simple, useful method for matching these types of antennas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antenna" title="antenna">antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=helix" title=" helix"> helix</a>, <a href="https://publications.waset.org/abstracts/search?q=helical" title=" helical"> helical</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20mode" title=" axial mode"> axial mode</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20power%20transfer" title=" wireless power transfer"> wireless power transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance%20matching" title=" impedance matching"> impedance matching</a> </p> <a href="https://publications.waset.org/abstracts/134308/impedance-matching-of-axial-mode-helical-antennas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134308.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">312</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> Rehabilitative Walking: The Development of a Robotic Walking Training Device Using Functional Electrical Stimulation for Treating Spinal Cord Injuries and Lower-Limb Paralysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chung%20Hyun%20Goh">Chung Hyun Goh</a>, <a href="https://publications.waset.org/abstracts/search?q=Armin%20Yazdanshenas"> Armin Yazdanshenas</a>, <a href="https://publications.waset.org/abstracts/search?q=X.%20Neil%20Dong"> X.

The purpose of this paper is to present the development and optimization of a training device that accurately recreates the motions in a gait cycle with the goal of rehabilitation for individuals with incomplete spinal cord injuries or who are victims of a stroke. A functional electrical stimulator was used in conjunction with the training device to stimulate muscle groups pertaining to rehabilitative walking. The feasibility and reliability of the design are presented. To validate the design functionality, motion analyses of the knee and ankle gait paths were made using motion capture systems.

Shotcrete thickness is a critical measure of the success of this process. 3D Laser Mapping, in conjunction with Jetcrete, has developed a 3D laser scanning system specifically for measuring the thickness of shotcrete. The system is mounted on the shotcrete spraying machine and measures the rock faces before and after spraying. The calculated difference between the two 3D surface models is measured as the thickness of the sprayed concrete. Typical work patterns for the shotcrete process required a rapid and automatic system. The scanning takes place immediately before and after the application of the shotcrete so no convergence takes place in the interval between scans. Automatic alignment of scans without targets was implemented which allows for the possibility of movement of the spraying machine between scans. Case studies are presented where accuracy tests are undertaken and automatic audit reports are calculated. The use of 3D imaging data for the calculation of shotcrete thickness is an important tool for geotechnical engineers and contract managers, and this could become the new state-of-the-art methodology for the mining industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20imaging" title="3D imaging">3D imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=shotcrete" title=" shotcrete"> shotcrete</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20model" title=" surface model"> surface model</a>, <a href="https://publications.waset.org/abstracts/search?q=tunnel%20stability" title=" tunnel stability"> tunnel stability</a> </p> <a href="https://publications.waset.org/abstracts/84408/shotcrete-performance-optimisation-and-audit-using-3d-laser-scanning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84408.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">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> A Longitudinal Study to Develop an Emotional Design Framework for Physical Activity Interventions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Hewitt">Stephanie Hewitt</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Sheldrick"> Leila Sheldrick</a>, <a href="https://publications.waset.org/abstracts/search?q=Weston%20Baxter"> Weston Baxter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multidisciplinary by nature, design research brings together varying research fields to answer globally significant questions. Emotional design, a field which helps us create products that influence people’s behaviour, and sports psychology, containing a growing field of recent research which focuses on understanding the emotions experienced through sport and the effects this has on our health and wellbeing, are two research fields that can be combined through design research to tackle global physical inactivity. The combination of these research fields presents an opportunity to build new tools and methods that could help designers create new interventions to promote positive behaviour change in the form of physical activity uptake, ultimately improving people’s health and wellbeing. This paper proposes a framework that can be used to develop new products and services that focus on not only improving the uptake and upkeep of physical activity but also helping people have a healthy emotional relationship with exercise. To develop this framework, a set of comprehensive maps exploring the relationship between human emotions and physical activity across a range of factors was created. These maps were then further evolved through in-depth interviews, which analysed the reasons behind the emotions felt, how physical activity fits into the daily routine and how important regular exercise is to people. Finally, to progress these findings into a design framework, a longitudinal study was carried out to explore further the emotional relationship people of varying sporting abilities have overtime with physical activity. This framework can be used to design more successful interventions that help people to not only become more active initially but implement long term changes to ensure they stay active. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20research" title="design research">design research</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20design" title=" emotional design"> emotional design</a>, <a href="https://publications.waset.org/abstracts/search?q=emotions" title=" emotions"> emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=intervention" title=" intervention"> intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a>, <a href="https://publications.waset.org/abstracts/search?q=sport%20psychology" title=" sport psychology"> sport psychology</a> </p> <a href="https://publications.waset.org/abstracts/128382/a-longitudinal-study-to-develop-an-emotional-design-framework-for-physical-activity-interventions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128382.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">47</span> Application of Artificial Neural Network and Background Subtraction for Determining Body Mass Index (BMI) in Android Devices Using Bluetooth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neil%20Erick%20Q.%20Madariaga">Neil Erick Q.

It is based on the height and weight of the person. This study aims to compute for the BMI using an Android tablet by obtaining the height of the person by using a camera and measuring the weight of the person by using a weighing scale or load cell. The height of the person was estimated by applying background subtraction to the image captured and applying different processes such as getting the vanishing point and applying Artificial Neural Network. The weight was measured by using Wheatstone bridge load cell configuration and sending the value to the computer by using Gizduino microcontroller and Bluetooth technology after the amplification using AD620 instrumentation amplifier. The application will process the images and read the measured values and show the BMI of the person. The study met all the objectives needed and further studies will be needed to improve the design project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20mass%20index" title="body mass index">body mass index</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title=" artificial neural network"> artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=vanishing%20point" title=" vanishing point"> vanishing point</a>, <a href="https://publications.waset.org/abstracts/search?q=bluetooth" title=" bluetooth"> bluetooth</a>, <a href="https://publications.waset.org/abstracts/search?q=wheatstone%20bridge%20load%20cell" title=" wheatstone bridge load cell"> wheatstone bridge load cell</a> </p> <a href="https://publications.waset.org/abstracts/20342/application-of-artificial-neural-network-and-background-subtraction-for-determining-body-mass-index-bmi-in-android-devices-using-bluetooth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20342.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">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Triggering Supersonic Boundary-Layer Instability by Small-Scale Vortex Shedding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guohua%20Tu">Guohua Tu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhi%20Fu"> Zhi Fu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiwei%20Hu"> Zhiwei Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20D%20Sandham"> Neil D Sandham</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianqiang%20Chen"> Jianqiang Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tripping of boundary-layers from laminar to turbulent flow, which may be necessary in specific practical applications, requires high amplitude disturbances to be introduced into the boundary layers without large drag penalties. As a possible improvement on fixed trip devices, a technique based on vortex shedding for enhancing supersonic flow transition is demonstrated in the present paper for a Mach 1.5 boundary layer. The compressible Navier-Stokes equations are solved directly using a high-order (fifth-order in space and third-order in time) finite difference method for small-scale cylinders suspended transversely near the wall. For cylinders with proper diameter and mount location, asymmetry vortices shed within the boundary layer are capable of tripping laminar-turbulent transition. Full three-dimensional simulations showed that transition was enhanced. A parametric study of the size and mounting location of the cylinder is carried out to identify the most effective setup. It is also found that the vortex shedding can be suppressed by some factors such as wall effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer%20instability" title="boundary layer instability">boundary layer instability</a>, <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer%20transition" title=" boundary layer transition"> boundary layer transition</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20shedding" title=" vortex shedding"> vortex shedding</a>, <a href="https://publications.waset.org/abstracts/search?q=supersonic%20flows" title=" supersonic flows"> supersonic flows</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20control" title=" flow control"> flow control</a> </p> <a href="https://publications.waset.org/abstracts/61412/triggering-supersonic-boundary-layer-instability-by-small-scale-vortex-shedding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61412.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Tapping into Debt: The Effect of Contactless Payment Methods on Overdraft Fee Occurrence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merle%20Van%20Den%20Akker">Merle Van Den Akker</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Stewart"> Neil Stewart</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Isoni"> Andrea Isoni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Contactless methods of payment referred to as tap&go, have become increasingly popular globally. However, little is known about the consequences of this payment method on spending, spending habits, personal finance management, and debt accumulation. The literature on other payment methods such as credit cards suggests that, through increased ease and reduced friction, the pain of paying in these methods is reduced, leading to higher and more frequent spending, resulting in higher debt accumulation. Within this research, we use a dataset of 300 million transactions of 165.000 individuals to see whether the onset of using contactless methods of payment increases the occurrence of overdraft fees. Using the R package MatchIt, we find, when matching people on initial overdraft occurrence and salary, that people who do start using contactless incur a significantly higher number of overdraft fees, as compared to those who do not start using contactless in the same year. Having accounted for income, opting-in, and time-of-year effects, these results show that contactless methods of payment fall within the scope of earlier theories on credit cards, such as the pain of paying, meaning that this payment method leads to increasing difficulties managing personal finance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contactless" title="contactless">contactless</a>, <a href="https://publications.waset.org/abstracts/search?q=debt%20accumulation" title=" debt accumulation"> debt accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=overdraft%20fees" title=" overdraft fees"> overdraft fees</a>, <a href="https://publications.waset.org/abstracts/search?q=payment%20methods" title=" payment methods"> payment methods</a>, <a href="https://publications.waset.org/abstracts/search?q=spending" title=" spending"> spending</a> </p> <a href="https://publications.waset.org/abstracts/114333/tapping-into-debt-the-effect-of-contactless-payment-methods-on-overdraft-fee-occurrence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114333.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">122</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> Process Safety Evaluation of a Nuclear Power Plant through Virtual Process Hazard Analysis Using Hazard and Operability Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elysa%20V.%20Largo">Elysa V.

The Philippines has the Bataan Nuclear Power Plant (BNPP), which can be a source of nuclear energy; however, it has not been operated since the completion of its construction. Thus, evaluating the safety of BNPP is vital. This study explored the possible deviations that may occur in the operation of a nuclear power plant with a pressurized water reactor, which is similar to BNPP, through a virtual process hazard analysis (PHA) using the hazard and operability (HAZOP) technique. Temperature, pressure, and flow were used as parameters. A total of 86 causes of various deviations were identified, wherein the primary system and line from reactor coolant pump to reactor vessel are the most critical system and node, respectively. A total of 348 scenarios were determined. The critical events are radioactive leaks due to nuclear meltdown and sump overflow that could lead to multiple worker fatalities, one or more public fatalities, and environmental remediation. There were existing safeguards identified; however, further recommendations were provided to have additional and supplemental barriers to reduce the risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PSM" title="PSM">PSM</a>, <a href="https://publications.waset.org/abstracts/search?q=PHA" title=" PHA"> PHA</a>, <a href="https://publications.waset.org/abstracts/search?q=HAZOP" title=" HAZOP"> HAZOP</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20power%20plant" title=" nuclear power plant"> nuclear power plant</a> </p> <a href="https://publications.waset.org/abstracts/152212/process-safety-evaluation-of-a-nuclear-power-plant-through-virtual-process-hazard-analysis-using-hazard-and-operability-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152212.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">154</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> Process Safety Evaluation of a Nuclear Power Plant through Virtual Process Hazard Analysis (PHA) using the What-If Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lormaine%20Anne%20Branzuela">Lormaine Anne Branzuela</a>, <a href="https://publications.waset.org/abstracts/search?q=Elysa%20Largo"> Elysa Largo</a>, <a href="https://publications.waset.org/abstracts/search?q=Julie%20Marisol%20Pagalilauan"> Julie Marisol Pagalilauan</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Concibido"> Neil Concibido</a>, <a href="https://publications.waset.org/abstracts/search?q=Monet%20Concepcion%20Detras"> Monet Concepcion Detras</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy is a necessity both for the people and the country. The demand for energy is continually increasing, but the supply is not doing the same. The reopening of the Bataan Nuclear Power Plant (BNPP) in the Philippines has been circulating in the media for the current time. The general public has been hesitant in accepting the inclusion of nuclear energy in the Philippine energy mix due to perceived unsafe conditions of the plant. This study evaluated the possible operations of a nuclear power plant, which is of the same type as the BNPP, considering the safety of the workers, the public, and the environment using a Process Hazard Analysis (PHA) method. What-If Technique was utilized to identify the hazards and consequences on the operations of the plant, together with the level of risk it entails. Through the brainstorming sessions of the PHA team, it was found that the most critical system on the plant is the primary system. Possible leakages on pipes and equipment due to weakened seals and welds and blockages on coolant path due to fouling were the most common scenarios identified, which further caused the most critical scenario – radioactive leak through sump contamination, nuclear meltdown, and equipment damage and explosion which could result to multiple injuries and fatalities, and environmental impacts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=process%20safety%20management" title="process safety management">process safety management</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20hazard%20analysis" title=" process hazard analysis"> process hazard analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=what-If%20technique" title=" what-If technique"> what-If technique</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20power%20plant" title=" nuclear power plant"> nuclear power plant</a> </p> <a href="https://publications.waset.org/abstracts/152198/process-safety-evaluation-of-a-nuclear-power-plant-through-virtual-process-hazard-analysis-pha-using-the-what-if-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152198.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">223</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> The Osteocutaneous Distal Tibia Turn-over Fillet Flap: A Novel Spare-parts Orthoplastic Surgery Option for Functional Below-knee Amputation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harry%20Burton">Harry Burton</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexios%20Dimitrios%20Iliadis"> Alexios Dimitrios Iliadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Jones"> Neil Jones</a>, <a href="https://publications.waset.org/abstracts/search?q=Aaron%20Saini"> Aaron Saini</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Bystrzonowski"> Nicola Bystrzonowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandros%20Vris"> Alexandros Vris</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgios%20Pafitanis"> Georgios Pafitanis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article portrays the authors’ experience with a complex lower limb bone and soft tissue defect, following chronic osteomyelitis and pathological fracture, which was managed by the multidisciplinary orthoplastic team. The decision for functional amputation versus limb salvage was deemed necessary, enhanced by the principles of “spares parts” in reconstructive microsurgery. This case describes a successful use of the osteocutaneous distal tibia turn-over fillet flap that allowed ‘lowering the level of the amputation’ from a through knee to the conventional level of a below-knee amputation to preserve the knee joint function. This case demonstrates the value of ‘spare-parts’ surgery principles and how these concepts refine complex orthoplastic approaches when limb salvage is not possible to enhance function. The osteocutaneous distal tibia turn-over fillet flap is a robust technique for modified BKA reconstructions that provides sufficient bone length to achieve a tough, sensate stump and functional knee joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteocutaneous%20flap" title="osteocutaneous flap">osteocutaneous flap</a>, <a href="https://publications.waset.org/abstracts/search?q=fillet%20flap" title=" fillet flap"> fillet flap</a>, <a href="https://publications.waset.org/abstracts/search?q=spare-parts%20surgery" title=" spare-parts surgery"> spare-parts surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=Below%20knee%20amputation" title=" Below knee amputation"> Below knee amputation</a> </p> <a href="https://publications.waset.org/abstracts/146660/the-osteocutaneous-distal-tibia-turn-over-fillet-flap-a-novel-spare-parts-orthoplastic-surgery-option-for-functional-below-knee-amputation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146660.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Analgesic Efficacy of Opiorphin and Its Analogue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Preet%20Singh">Preet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Kavitha%20Kongara"> Kavitha Kongara</a>, <a href="https://publications.waset.org/abstracts/search?q=Dave%20Harding"> Dave Harding</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Ward"> Neil Ward</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Chambers"> Paul Chambers</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to compare the analgesic efficacy of opiorphin and its analogue with a mu-receptor agonist; morphine. Opiorphins (Gln-Arg-Phe-Ser-Arg) belong to the family of endogenous enkephalinase inhibitors, found in saliva of humans. They are inhibitors of two Zinc metal ectopeptidases (Neutral endopeptidase NEP, and amino-peptidase APN) which are responsible for the inactivation of the endogenous opioids; endorphins and enkephalins. Morphine and butorphanol exerts their analgesic effects by mimicking the actions of endorphins and enkephalins. The opiorphin analogue was synthesized based on the structure activity relationship of the amino acid sequence of opiorphin. The pharmacological profile of the analogue was tested by replacing Serine at position 4 with Proline. The hot plate and tail flick test were used to demonstrate the analgesic efficacy. There was a significant increase in the time for the tail flick response after an injection of opiorphin, which was similar to the morphine effect. There was no increase in time in the hot plate test after an injection of opiorphin. The results suggest that opiorphin works at spinal level only rather than both spinal and supraspinal. Further work is required to confirm our results. We did not find analgesic activity of the opiorphin analogue. Thus, Serine at position 4 is also important for its pharmacological action. Further work is required to illustrate the role of serine at position 4 in opiorphin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analgesic%20peptides" title="analgesic peptides">analgesic peptides</a>, <a href="https://publications.waset.org/abstracts/search?q=endogenous%20opioids" title=" endogenous opioids"> endogenous opioids</a>, <a href="https://publications.waset.org/abstracts/search?q=morphine" title=" morphine"> morphine</a>, <a href="https://publications.waset.org/abstracts/search?q=opiorphin" title=" opiorphin"> opiorphin</a> </p> <a href="https://publications.waset.org/abstracts/51800/analgesic-efficacy-of-opiorphin-and-its-analogue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51800.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">325</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> Assessment of Post-surgical Donor-Site Morbidity in Vastus lateralis Free Flap for Head and Neck Reconstructive Surgery: An Observational Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ishith%20Seth">Ishith Seth</a>, <a href="https://publications.waset.org/abstracts/search?q=Lyndel%20Hewitt"> Lyndel Hewitt</a>, <a href="https://publications.waset.org/abstracts/search?q=Takako%20Yabe"> Takako Yabe</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Wykes"> James Wykes</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Clark"> Jonathan Clark</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruce%20Ashford"> Bruce Ashford</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Vastus lateralis (VL) can be used to reconstruct defects of the head and neck. Whilst the advantages are documented, donor-site morbidity is not well described. This study aimed to assess donor-site morbidity after VL flap harvest. The results will determine future directions for preventative and post-operative care to improve patient health outcomes. Methods: Ten participants (mean age 55 years) were assessed for the presence of donor-site morbidity after VL harvest. Musculoskeletal (pain, muscle strength, muscle length, tactile sensation), quality of life (SF-12), and lower limb function (lower extremity function, gait (function and speed), sit to stand were assessed using validated and standardized procedures. Outcomes were compared to age-matched healthy reference values or the non-operative side. Analyses were conducted using descriptive statistics and non-parametric tests. Results: There was no difference in muscle strength (knee extension), muscle length, ability to sit-to-stand, or gait function (all P > 0.05). Knee flexor muscle strength was significantly less on the operated leg compared to the non-operated leg (P=0.02) and walking speed was slower than age-matched healthy values (P<0.001). Thigh tactile sensation was impaired in 89% of participants. Quality of life was significantly less for the physical health component of the SF-12 (P<0.001). The mental health component of the SF-12 was similar to healthy controls (P=0.26). Conclusion: There was no effect on donor site morbidity with regards to knee extensor strength, pain, walking function, ability to sit-to-stand, and muscle length. VL harvest affected donor-site knee flexion strength, walking speed, tactile sensation, and physical health-related quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vastus%20lateralis" title="vastus lateralis">vastus lateralis</a>, <a href="https://publications.waset.org/abstracts/search?q=morbidity" title=" morbidity"> morbidity</a>, <a href="https://publications.waset.org/abstracts/search?q=head%20and%20neck" title=" head and neck"> head and neck</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=donor-site%20morbidity" title=" donor-site morbidity"> donor-site morbidity</a> </p> <a href="https://publications.waset.org/abstracts/141308/assessment-of-post-surgical-donor-site-morbidity-in-vastus-lateralis-free-flap-for-head-and-neck-reconstructive-surgery-an-observational-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141308.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">242</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> The Ra 9262 (Anti-Violence Against Women and Their Children Act of 2004) in the Literature Classroom via the Movie ‘Enough’</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jay%20Neil%20Garciso%20Verano">Jay Neil Garciso Verano</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Rosales%20Bobiles"> Peter Rosales Bobiles</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study tried to integrate RA 9262 in literature through the use of film. It identified RA 9262 provisions reflected in the students’ concepts in their oral participation and written outputs and pointed out different attitudes toward violence against women and respect to women as shaped by the film through their responses. Four Literature 121 (World Literature) classes with more or less similar characteristics participated in this study. The discussion of Paulette Kelly’s I Got Flowers Today took place during the first session while the viewing of the film Enough and discussion of the film followed to enrich and bolster students’ concepts and awareness on violence against women and to introduce RA 9262 provisions. The students’ attitudes toward violence against women and respect to women were lifted from the students’ oral and written responses. The film Enough presented eight provisions from RA 9262 reflected in students’ concepts which centered on the acts of violence against women tarnishing women’s rights and dignity. There were 25 attitudes toward violence against women and respect to women which surfaced, 11 of which are what initiate the acts, seven tell about the results from or effects of violence against women, and another seven exemplify respect to women. With the findings, it can be viewed that RA 9262 can be integrated in a literature course to awaken students’ minds on the prevalent issues on violating women’s rights and dignity. The discussion of Paulette Kelly’s I Got Flowers Today reinforced by the viewing of Enough deduced issues on the violation of women’s rights and dignity, attitudes toward violence against women, and students’ perception with regard respect to women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-violence%20against%20women" title="anti-violence against women">anti-violence against women</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=film" title=" film"> film</a>, <a href="https://publications.waset.org/abstracts/search?q=enough" title=" enough"> enough</a>, <a href="https://publications.waset.org/abstracts/search?q=feminism" title=" feminism"> feminism</a> </p> <a href="https://publications.waset.org/abstracts/21906/the-ra-9262-anti-violence-against-women-and-their-children-act-of-2004-in-the-literature-classroom-via-the-movie-enough" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21906.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">380</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> Does Women Involvement in Politics Decrease Corruption?

Understanding corruption’s linkages to gender equality issues and how it impacts women’s empowerment is part of the broader process of advancing women’s rights and understanding the gender dimensions of democratic governance. Taking a long view of political (corruption index) and the social (women empowerment) dimension — a view from 2015 to 2030, a context based forecast was conducted to forecast the ASEAN corruption index in the next 15 years, answering the question: “Does women political involvement decrease corruption rate index of ASEAN countries in the next 15 years?” The study have established that there will be an increase women political involvement in the ASEAN countries in the next 15 years that will cause a drop on corruption rate index. There will be a significant decline on corruption rate index in 2030. This change entails reform not only in the political aspect of progress, but to the social aspect as well. Finally, the political aspect is increasing at a constant rate however a double or triple increase of the social aspect is seen to be the key solution for corruption. <p
