Bongo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The demanding, professional roles that air traffic controllers (ATC) play in air transport operation provided the main motivation of this paper. As the controllers’ workload stress becomes more complex due to various stressors, the challenge to overcome these in the pursuit of improving the efficiency of controllers and safety level of aircrafts has been relevant. Therefore, in order to determine the main stressors and surface the best alternative, two widely-known multi-criteria decision-making (MCDM) methods, DANP and PROMETHEE II, are applied. The proposed method is demonstrated in a case study at Mactan Civil Aviation Authority of the Philippines (CAAP). The results showed that the main stressors are high air traffic volume, extraneous traffic, unforeseen events, limitations and reliability of equipment, noise/distracter, micro climate, bad posture, relations with supervisors and colleagues, private life conditions/relationships, and emotional conditions. In the outranking of alternatives, compartmentalization is believed to be the most preferred alternative to overcome controllers’ workload stress. This implies that compartmentalization can best be applied to reduce controller workload stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20traffic%20controller" title="air traffic controller">air traffic controller</a>, <a href="https://publications.waset.org/abstracts/search?q=DANP" title=" DANP"> DANP</a>, <a href="https://publications.waset.org/abstracts/search?q=MCDM" title=" MCDM"> MCDM</a>, <a href="https://publications.waset.org/abstracts/search?q=PROMETHEE%20II" title=" PROMETHEE II"> PROMETHEE II</a>, <a href="https://publications.waset.org/abstracts/search?q=workload%20stress" title=" workload stress"> workload stress</a> </p> <a href="https://publications.waset.org/abstracts/59239/an-integrated-danp-promethee-ii-approach-for-air-traffic-controllers-workload-stress-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59239.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">73</span> Exploring Visual Arts through the Blue Humanities: The Case Study of Jason deCaires Taylor's Underwater Sculptures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Muharram">Mohammed Muharram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Blue Humanities aims to deepen our understanding of the oceans through the integration of arts and sciences, emphasizing their cultural, historical, and ecological significance. This study explores the role of visual arts within this interdisciplinary framework, focusing on the underwater sculptures of Jason deCaires Taylor as a case study. The research employs a multidisciplinary approach, combining art history, environmental science, and cultural studies to explore the significance of Taylor's underwater installations. Methodologies include analysis of the artistic elements and themes in Taylor's work, assessment of the ecological impact of the sculptures on marine environments, and examination of the cultural narratives they evoke. Key findings highlight how Taylor's sculptures serve as artificial reefs, promoting marine biodiversity while simultaneously raising awareness about ocean conservation. The artworks act as powerful symbols, merging environmental activism with artistic expression and transforming underwater spaces into immersive art galleries that challenge traditional notions of viewing art. By bridging the gap between visual arts and environmental science, this study demonstrates how Taylor's sculptures contribute to the Blue Humanities by fostering a deeper, more holistic appreciation of the marine world. The research advocates for the continued integration of artistic perspectives into marine conservation efforts, emphasizing the role of visual arts in shaping public perceptions and promoting ecological sustainability. In conclusion, this study underscores the transformative potential of visual arts within the Blue Humanities, exemplified by Jason deCaires Taylor's underwater sculptures, which inspire both aesthetic appreciation and environmental consciousness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blue%20humanities" title="blue humanities">blue humanities</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20art" title=" visual art"> visual art</a>, <a href="https://publications.waset.org/abstracts/search?q=underwater%20sculptures" title=" underwater sculptures"> underwater sculptures</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20deCaires%20Taylor" title=" Jason deCaires Taylor"> Jason deCaires Taylor</a> </p> <a href="https://publications.waset.org/abstracts/188792/exploring-visual-arts-through-the-blue-humanities-the-case-study-of-jason-decaires-taylors-underwater-sculptures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188792.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">26</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">72</span> Parents' Perception on the Use of Mobile Technology by Young Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20Gan">Jason Gan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Technology has been around for many years, those that play a crucial part of our lives have evolved quick and fast, from televisions to computers and now mobile technology has also become a part of our lives.

This public marginalization is crucial to be dealt with because undermining opinion of majority may cause problems such as protests and/ or low demand. Game theory approach applied in this paper shows that probability of public acceptance towards a project is affected by overall public’s perception on Private sectors’ possible profit accumulation from the project. On the contrary, goodwill of the government and private coalition alone is not enough to minimize the probability of public opposition towards a PPP project. Additionally, the threat of loss or damage raised from public opposition does not affect the profit-maximization behavior of Private sectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20satisfaction" title="community satisfaction">community satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20theory" title=" game theory"> game theory</a>, <a href="https://publications.waset.org/abstracts/search?q=non-cooperative" title=" non-cooperative"> non-cooperative</a>, <a href="https://publications.waset.org/abstracts/search?q=PPP" title=" PPP"> PPP</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20policy" title=" public policy"> public policy</a> </p> <a href="https://publications.waset.org/abstracts/60803/non-cooperative-game-theory-approach-for-ensuring-community-satisfaction-on-public-private-partnership-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60803.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">695</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">70</span> Assessing Student Collaboration in Music Ensemble Class: From the Formulation of Grading Rubrics to Their Effective Implementation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20Sah">Jason Sah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Music ensemble class is a non-traditional classroom in the sense that it is always a group effort during rehearsal. When measuring student performance ability in class, it is imperative that the grading rubric includes a collaborative skill component. Assessments that stop short of testing students' ability to make music with others undermine the group mentality by elevating individual prowess. Applying empirical and evidence-based methodology, this research develops a grading rubric that defines the criteria for assessing collaborative skill, and then explores different strategies for implementing this rubric in a timely and effective manner. Findings show that when collaborative skill is regularly tested, students gradually shift their attention from playing their own part well to sharing their part with others. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=ensemble%20class" title=" ensemble class"> ensemble class</a>, <a href="https://publications.waset.org/abstracts/search?q=grading%20rubric" title=" grading rubric"> grading rubric</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20collaboration" title=" student collaboration"> student collaboration</a> </p> <a href="https://publications.waset.org/abstracts/112833/assessing-student-collaboration-in-music-ensemble-class-from-the-formulation-of-grading-rubrics-to-their-effective-implementation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112833.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">135</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">69</span> Optimal Linear Quadratic Digital Tracker for the Discrete-Time Proper System with an Unknown Disturbance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20Sheng-Hong%20Tsai">Jason Sheng-Hong Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Faezeh%20Ebrahimzadeh"> Faezeh Ebrahimzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Ching%20Chung"> Min-Ching Chung</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu-Mei%20Guo"> Shu-Mei Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Leang-San%20Shieh"> Leang-San Shieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzong-Jiy%20Tsai"> Tzong-Jiy Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Wang"> Li Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we first construct a new state and disturbance estimator using discrete-time proportional plus integral observer to estimate the system state and the unknown external disturbance for the discrete-time system with an input-to-output direct-feedthrough term.

It is quite difficult to search the search space of the optimization problem with large dimensions. There is a challenge to use all the cores of the system. In this study, a sequential implementation of the memetic algorithm is converted into a concurrent version, which is executed on the cores of both CPU and GPU. For this reason, CUDA and OpenMP libraries are operated on the parallel algorithm to make a concurrent execution on CPU and GPU, respectively. The aim of this study is to compare CPU and GPU implementation of the memetic algorithm. For this purpose, fourteen benchmark functions are selected as test problems. The obtained results indicate that our approach leads to speedups up to five thousand times higher compared to one CPU thread while maintaining a reasonable results quality. This clearly shows that GPUs have the potential to acceleration of MAs and allow them to solve much more complex tasks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=memetic%20algorithm" title="memetic algorithm">memetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=CUDA" title=" CUDA"> CUDA</a>, <a href="https://publications.waset.org/abstracts/search?q=GPU-based%20memetic%20algorithm" title=" GPU-based memetic algorithm"> GPU-based memetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20multi%20processing" title=" open multi processing"> open multi processing</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodal%20functions" title=" multimodal functions"> multimodal functions</a>, <a href="https://publications.waset.org/abstracts/search?q=unimodal%20functions" title=" unimodal functions"> unimodal functions</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20optimization%20problems" title=" non-linear optimization problems"> non-linear optimization problems</a> </p> <a href="https://publications.waset.org/abstracts/162791/comparison-of-parallel-cuda-and-openmp-implementations-of-memetic-algorithms-for-solving-optimization-problems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162791.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">101</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">67</span> From Manipulation to Citizen Control: A Case Study Revealing the Level of Participation in the Citizen Participatory Audit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Jason%20E.%20Arca">Mark Jason E.

The proper integration of participants in the decision-making process should be properly addressed to ensure effectiveness. This study explores the integration of the participants in the decision-making process to reveal the level of participation in the Solid Waste Management audit done by the Citizen Participatory Audit (CPA), a program under the supervision of the Commission on Audit. Specifically, this study will use the experience of participation to identify emerging themes that will help reveal the level of participation through the integrated ladder of participation. The researchers used key informant interviews to gather necessary data from the actors of the program. The findings revealed that the level of participation present in the CPA is at the Placation level, a level below the program’s targeted level of participation. The study also allowed the researchers to reveal facilitating factors in the program that contributed to a better understanding of the practice of participation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citizen%20participation" title="citizen participation">citizen participation</a>, <a href="https://publications.waset.org/abstracts/search?q=culture%20of%20participation" title=" culture of participation"> culture of participation</a>, <a href="https://publications.waset.org/abstracts/search?q=ladder%20of%20participation" title=" ladder of participation"> ladder of participation</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20participation" title=" level of participation"> level of participation</a> </p> <a href="https://publications.waset.org/abstracts/56864/from-manipulation-to-citizen-control-a-case-study-revealing-the-level-of-participation-in-the-citizen-participatory-audit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56864.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">411</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> Structural Performances of Rubberized Concrete Wall Panel Utilizing Fiber Cement Board as Skin Layer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20Ting%20Jing%20Cheng">Jason Ting Jing Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Foo%20Wei"> Lee Foo Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Yew%20Ming%20Kun"> Yew Ming Kun</a>, <a href="https://publications.waset.org/abstracts/search?q=Mo%20Kim%20Hung"> Mo Kim Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Yip%20Chun%20Chieh"> Yip Chun Chieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research delves into the structural characteristics of distinct construction material, rubberized lightweight foam concrete (RLFC) wall panels, which have been developed as a sustainable alternative for the construction industry. These panels are engineered with a RLFC core, possessing a density of 1150 kg/m3, which is specifically formulated to bear structural loads. The core is enveloped with high-strength fiber cement boards, selected for their superior load-bearing capabilities, and enhanced flexural strength when compared to conventional concrete. A thin bed adhesive, known as TPS, is employed to create a robust bond between the RLFC core and the fiber cement cladding. This study underscores the potential of RLFC wall panels as a viable and eco-friendly option for modern building construction, offering a combination of structural efficiency and environmental benefits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structural%20performance" title="structural performance">structural performance</a>, <a href="https://publications.waset.org/abstracts/search?q=rubberized%20concrete%20wall%20panel" title=" rubberized concrete wall panel"> rubberized concrete wall panel</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber%20cement%20board" title=" fiber cement board"> fiber cement board</a>, <a href="https://publications.waset.org/abstracts/search?q=insulation%20performance" title=" insulation performance"> insulation performance</a> </p> <a href="https://publications.waset.org/abstracts/183246/structural-performances-of-rubberized-concrete-wall-panel-utilizing-fiber-cement-board-as-skin-layer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183246.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">62</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> Empirical Heat Transfer Correlations of Finned-Tube Heat Exchangers in Pulsatile Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20P.%20Michaud">Jason P.

Three radiators found in desktop computers sized for 120 mm fans were tested in steady and pulsatile flows of ambient air over a Reynolds number range of  50 < Re < 900. Water at 60 °C was circulated through the radiators to maintain a constant fin temperature during the tests. For steady flow, it was found that the heat transfer rate increased linearly with the mass flow rate of air. The pulsatile flow experiments showed that frequency of pulsation had a negligible effect on the heat transfer rate for the range of frequencies tested (0.5 Hz – 2.5 Hz). For all three radiators, the heat transfer rate was decreased in the case of pulsatile flow. Linear heat transfer correlations for steady and pulsatile flow were calculated in terms of Reynolds number and Nusselt number. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finned-tube%20heat%20exchangers" title="finned-tube heat exchangers">finned-tube heat exchangers</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer%20correlations" title=" heat transfer correlations"> heat transfer correlations</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsatile%20flow" title=" pulsatile flow"> pulsatile flow</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20radiators" title=" computer radiators"> computer radiators</a> </p> <a href="https://publications.waset.org/abstracts/59633/empirical-heat-transfer-correlations-of-finned-tube-heat-exchangers-in-pulsatile-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59633.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">506</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> A Topological Approach for Motion Track Discrimination</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tegan%20H.%20Emerson">Tegan H.

Moreover, this lack of spatial information also disqualifies the use of most state-of-the-art deep learning image-based classifiers. Here, we use characteristics of target tracks extracted from video sequences as data from which to derive distinguishing topological features that help robustly differentiate targets of interest from confusers. In particular, we calculate persistent homology from time-delayed embeddings of dynamic statistics calculated from motion tracks extracted from a wide field-of-view video stream. In short, we use topological methods to extract features related to target motion dynamics that are useful for classification and disambiguation and show that small targets can be detected at range with high probability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motion%20tracks" title="motion tracks">motion tracks</a>, <a href="https://publications.waset.org/abstracts/search?q=persistence%20images" title=" persistence images"> persistence images</a>, <a href="https://publications.waset.org/abstracts/search?q=time-delay%20embedding" title=" time-delay embedding"> time-delay embedding</a>, <a href="https://publications.waset.org/abstracts/search?q=topological%20data%20analysis" title=" topological data analysis"> topological data analysis</a> </p> <a href="https://publications.waset.org/abstracts/128723/a-topological-approach-for-motion-track-discrimination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128723.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">114</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> Design and Construction of an Impulse Current Generator for Lightning Strike Experiments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamran%20Yousefpour">Kamran Yousefpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Rostaghi-Chalaki"> Mojtaba Rostaghi-Chalaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Warden"> Jason Warden</a>, <a href="https://publications.waset.org/abstracts/search?q=Chanyeop%20Park"> Chanyeop Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There has been a rising trend in using impulse current generators to investigate the lightning strike protection of materials including aluminum and composites in structures such as wind turbine blade and aircraft body.

Applying narrative analysis techniques to current public discourses in education that run counter to scientific findings, it becomes possible to identify weakness in modern pedagogy and suggest ways to counter false narratives in the classroom. Results of this study indicate that a failure to engage with popular narratives lessens teachers’ ability to be convincing in the classroom, even when presenting information supported by scientific evidence. This study seeks to empower teachers by illustrating the influence of story within the post-truth era and the ways in which narrative and rhetorical elements take hold in social media contexts. Equipped with this knowledge, teachers can create a shift in pedagogy, away from transmission of knowledge toward the crafting of powerful narratives, built upon evidence, and connected to the lives of modern learners. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=21st%20century%20learner" title="21st century learner">21st century learner</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20pedagogy" title=" critical pedagogy"> critical pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative" title=" narrative"> narrative</a>, <a href="https://publications.waset.org/abstracts/search?q=post-truth%20era" title=" post-truth era"> post-truth era</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a> </p> <a href="https://publications.waset.org/abstracts/89618/teaching-in-the-post-truth-era-a-narrative-analysis-of-modern-anti-scientific-discourses-in-the-classroom" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89618.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">266</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> Assessment of Prevalent Diseases Caused by Mining Activities in the Northern Part of Mindanao Island, Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Odinah%20Cuartero-Enteria">Odinah Cuartero-Enteria</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyla%20Rita%20Mercado"> Kyla Rita Mercado</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Salamanes"> Jason Salamanes</a>, <a href="https://publications.waset.org/abstracts/search?q=Aian%20Pecasales"> Aian Pecasales</a>, <a href="https://publications.waset.org/abstracts/search?q=Sherwin%20Sabado"> Sherwin Sabado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The northern part of Mindanao Island, Philippines has sizable reserve of mineral resources. Years ago, mining activities have been flourishing which resulted to both local economic gain but with environmental concerns. This study investigates the prevalent diseases by mining activities in these areas. The study was done using the secondary data gathered from the Rural Health Units (RHU) of the selected areas. The study further determined the prevalent diseases that existed in the three areas from years 2005, 2010 and 2015 indicating before the mining activities and when mining activities are present. The results show that areas which are far from mining activities have fewer cases of patients suffering from air-borne diseases. The top ten most common diseases such as pneumonia, tuberculosis, influenza, upper respiratory tract infection (URTI) and skin diseases were caused by air-borne due to air pollution. Hence, the places where mining activities are present contribute to the prevalent diseases. Thus, addressing the air pollution caused by mining activities is very important. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philippines" title="Philippines">Philippines</a>, <a href="https://publications.waset.org/abstracts/search?q=Mindanao%20Island" title=" Mindanao Island"> Mindanao Island</a>, <a href="https://publications.waset.org/abstracts/search?q=mining%20activities" title=" mining activities"> mining activities</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalent%20diseases" title=" prevalent diseases"> prevalent diseases</a> </p> <a href="https://publications.waset.org/abstracts/81416/assessment-of-prevalent-diseases-caused-by-mining-activities-in-the-northern-part-of-mindanao-island-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81416.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">473</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> Assessing Immunization across Life Stages of the Cuban Treefrog (Osteopilus septentrionalis) to the Pathogenic Chytrid Fungus (Batrachochytrium dendrobatidis)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kerri%20L.%20Surbaugh">Kerri L.

The chytrid fungus, Batrachochytrium dendrobatidis (Bd), ranks among the chief pathogenic challenges to vulnerable amphibian populations. Although live Bd can immunosuppress amphibian hosts, amphibian exposure to dead Bd can induce an adaptive immune response, leading to acquired resistance to the pathogen. In this experiment, dose and duration of flash-frozen Bd were manipulated over a variety of life-stages of the Cuban treefrog (Osteopilus septentrionalis) and the magnitude of acquired resistance to the pathogen was quantified via qPCR analyses of spore abundance post subsequent live Bd challenges. It was found that Cuban treefrogs can develop resistance to Bd and that life stage, dose and duration thresholds exist for acquired resistance. This experiment will aid in facilitating the development of a vaccine against Bd which could be used on location and could help curb worldwide amphibian declines associated with this pathogen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acquired%20resistance" title="acquired resistance">acquired resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=ecoimmunology" title=" ecoimmunology"> ecoimmunology</a>, <a href="https://publications.waset.org/abstracts/search?q=emerging%20infectious%20disease" title=" emerging infectious disease"> emerging infectious disease</a>, <a href="https://publications.waset.org/abstracts/search?q=fungal%20host%20response" title=" fungal host response"> fungal host response</a>, <a href="https://publications.waset.org/abstracts/search?q=fungal%20pathogen" title=" fungal pathogen"> fungal pathogen</a>, <a href="https://publications.waset.org/abstracts/search?q=immunization" title=" immunization"> immunization</a> </p> <a href="https://publications.waset.org/abstracts/104519/assessing-immunization-across-life-stages-of-the-cuban-treefrog-osteopilus-septentrionalis-to-the-pathogenic-chytrid-fungus-batrachochytrium-dendrobatidis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104519.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">133</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> Mining Coupled to Agriculture: Systems Thinking in Scalable Food Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20West">Jason West</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Low profitability in agriculture production along with increasing scrutiny over environmental effects is limiting food production at scale. In contrast, the mining sector offers access to resources including energy, water, transport and chemicals for food production at low marginal cost. Scalable agricultural production can benefit from the nexus of resources (water, energy, transport) offered by mining activity in remote locations. A decision support bioeconomic model for controlled environment vertical farms was used. Four submodels were used: crop structure, nutrient requirements, resource-crop integration, and economic. They escalate to a macro mathematical model. A demonstrable dynamic systems framework is needed to prove productive outcomes are feasible. We demonstrate a generalized bioeconomic macro model for controlled environment production systems in minesites using systems dynamics modeling methodology. Despite the complexity of bioeconomic modelling of resource-agricultural dynamic processes and interactions, the economic potential greater than general economic models would assume. Scalability of production as an input becomes a key success feature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crop%20production%20systems" title="crop production systems">crop production systems</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a>, <a href="https://publications.waset.org/abstracts/search?q=mining" title=" mining"> mining</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20systems" title=" dynamic systems"> dynamic systems</a> </p> <a href="https://publications.waset.org/abstracts/150725/mining-coupled-to-agriculture-systems-thinking-in-scalable-food-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150725.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">77</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> Relationships between Financial, Cultural, Emotional, and General Wellbeing: A Structural Equation Modeling Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Alsop">Michael Alsop</a>, <a href="https://publications.waset.org/abstracts/search?q=Hannah%20Heitz"> Hannah Heitz</a>, <a href="https://publications.waset.org/abstracts/search?q=Prathiba%20Natesan%20Batley"> Prathiba Natesan Batley</a>, <a href="https://publications.waset.org/abstracts/search?q=Marion%20Hambrick"> Marion Hambrick</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Immekus"> Jason Immekus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impacts of cultural engagement on individuals’ health and well-being have been well documented. The purposes of this study were to create an instrument to measure wellbeing constructs, including cultural wellbeing, and explore the relationships between cultural wellbeing and other wellbeing constructs (e.g., emotional, social, physical, spiritual). A sample of 358 participants attending concerts performed by a civic orchestra in the southeastern United States completed a questionnaire designed to measure eight wellbeing constructs. Split-half exploratory, confirmatory factor analyses resulted in the retention of four wellbeing constructs: general, emotional, financial, and cultural. Structural equation modeling showed statistically significant relationships between cultural wellbeing and other wellbeing constructs. In addition to the indirect effect of financial wellbeing on emotional and general wellbeing through cultural wellbeing, there were also direct statistically significant relationships (i.e., moderator). This highlights the importance of removing financial barriers to cultural engagement and the relationship between cultural wellbeing on emotional and general wellbeing. Additionally, the retained cultural wellbeing items focused primarily on community features, indicating the value of community-based cultural engagement opportunities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20wellbeing" title="cultural wellbeing">cultural wellbeing</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20engagement" title=" cultural engagement"> cultural engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20analysis" title=" factor analysis"> factor analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20equation%20modeling" title=" structural equation modeling"> structural equation modeling</a> </p> <a href="https://publications.waset.org/abstracts/167360/relationships-between-financial-cultural-emotional-and-general-wellbeing-a-structural-equation-modeling-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167360.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">82</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> Abundance and Diversity of Fruit Flies (Tephritidae: Diptera) In Citrus Orchards in Sindhuli, Nepal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debraj%20Adhikari">Debraj Adhikari</a>, <a href="https://publications.waset.org/abstracts/search?q=Resham%20Bahadur%20Thapa"> Resham Bahadur Thapa</a>, <a href="https://publications.waset.org/abstracts/search?q=Samudra%20Lal%20Joshi"> Samudra Lal Joshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Jinping%20Du"> Jason Jinping Du</a>, <a href="https://publications.waset.org/abstracts/search?q=Sundar%20Tiwari"> Sundar Tiwari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to keep a record of fruit fly species (Tephritidae: Diptera) in the sweet orange orchards of Sindhuli district, Nepal. Male fruit fly species were trapped and collected fortnightly using para-pheromone lures (methyl eugenol and cue lure) in Steiner traps at 25 orchards starting in March 2019 and continuing until February 2021. During the monitoring period, there was a significant variation in the occurrence of the fruit fly species. Fruit flies were captured in greater numbers during warm and rainy months (June, July, August, September) than during dry and winter months (December, January, February). Higher numbers of fruit flies were trapped in methyl eugenol than cue lure traps. Bactrocera dorsalis, B. zonata were major fruit fly species trapped in the methyl eugenol trap. Whereas, Zeugodacus tau, Z. cucurbitae, Z. scutellaris, and Dacus longicornis were major fruit fly species trapped in the cue lure trap.

As a result, if workplace violence, particularly in healthcare settings, is not adequately addressed, it will become a phenomenon, undermining the peace and stability among the active communities while also posing a risk to the population's health and well-being. This review intends to identify the risk factors and the implications of workplace violence in healthcare settings and highlight the collaborative efforts needed in sustaining control and prevention measures against workplace violence. It is essential that health care organizations are prepared physically and emotionally for traumatic situations. This study explores the theoretical nature of addressing work-related violence in healthcare settings as well as traumatic stress reactivity and the context within which reactions occur and recovery takes place. Cognitive, social, and organizational influences on response are identified and used to tentatively offer explanations for identifying security risks, development, and implementation of de-escalation teams, CISM programs and training staff in violence prevention are among strategies hospitals are employing to keep workers and patients safe. General conclusion regarding the implications for intervention effectiveness and design are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthcare%20settings" title="healthcare settings">healthcare settings</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20reactions" title=" stress reactions"> stress reactions</a>, <a href="https://publications.waset.org/abstracts/search?q=traumatic%20events" title=" traumatic events"> traumatic events</a>, <a href="https://publications.waset.org/abstracts/search?q=workplace%20violence" title=" workplace violence"> workplace violence</a> </p> <a href="https://publications.waset.org/abstracts/170808/when-helping-hurts-addressing-violence-in-healthcare-settings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170808.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">55</span> In vivo Antiplatelet Activity Test of Wet Extract of Mimusops elengi L.'s Leaves on DDY Strain Mice as an Effort to Treat Atherosclerosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Tristantini">Dewi Tristantini</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Jonathan"> Jason Jonathan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coronary Artery Disease (CAD) is one of the deathliest diseases which is caused by atherosclerosis. Atherosclerosis is a disease that plaque builds up inside the arteries. Plaque is made up of fat, cholesterol, calcium, platelet, and other substances found in blood. The current treatment of atherosclerosis is to provide antiplatelet therapy treatment, but such treatments often cause gastrointestinal irritation, muscle pain and hormonal imbalance. Mimusops elengi L.’s leaves can be utilized as a natural and cheap antiplatelet’s source because it contains flavonoids such as quertecin. Antiplatelet aggregation effect of Mimusops elengi L.’s leaves’ wet extract was measured by bleeding time on DDY strain mice with the test substances were given orally during the period of 8 days. The bleeding time was measured on first day and 9th day. Empirically, the dose which is used for humans is 8.5 g of leaves in 600 ml of water. This dose is equivalent to 2.1 g of leaves in 350 ml of water for mice. The extract was divided into 3 doses for mice: 0.05 ml/day; 0.1 ml/day; 0.2 ml/day. After getting the percentage of the increase in bleeding time, data were analyzed by analysis of variance test (Anova), followed by individual comparison within the groups by LSD test. The test substances above respectively increased bleeding time 21%, 62%, and 128%. As the conclusion, the 0.02 ml/day dose of Mimusops elengi L.’s leaves’ wet extract could increase bleeding time better than clopidogrel as positive controls with 110% increase in bleeding time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiplatelets" title="antiplatelets">antiplatelets</a>, <a href="https://publications.waset.org/abstracts/search?q=atheroschlerosis" title=" atheroschlerosis"> atheroschlerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bleeding%20time" title=" bleeding time"> bleeding time</a>, <a href="https://publications.waset.org/abstracts/search?q=Mimusops%20elengi" title=" Mimusops elengi"> Mimusops elengi</a> </p> <a href="https://publications.waset.org/abstracts/39257/in-vivo-antiplatelet-activity-test-of-wet-extract-of-mimusops-elengi-ls-leaves-on-ddy-strain-mice-as-an-effort-to-treat-atherosclerosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39257.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">264</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> The Impact of Major Accounting Events on Managerial Ability and the Accuracy of Environmental Capital Expenditure Projections of the Environmentally Sensitive Industries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20Chen">Jason Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jennifer%20Chen"> Jennifer Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiyu%20Li"> Shiyu Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We examine whether managerial ability (MA), the passing of Sarbanes-Oxley in 2002 (SOX), and corporate operational complexity affect the accuracy of environmental capital expenditure projections of the environmentally sensitive industries (ESI). Prior studies found that firms in the ESI manipulated their projected environmental capital expenditures as a tool to achieve corporate legitimation and suggested that human factors must be examined to determine whether they are part of the determinants. We use MA to proxy for the latent human factors to examine whether MA affects the accuracy of financial disclosures in the ESI. To expand Chen and Chen (2020), we further investigate whether (1) SOX and (2) firms with complex operations and financial reporting in conjunction with MA affect firms’ projection accuracy. We find, overall, that MA is positively correlated with firm’s projection accuracy in the annual 10-Ks. Furthermore, results suggest that SOX has a positive, yet temporary, effect on MA, and that leads to better accuracy. Finally, MA matters for firms with more complex operations and financial reporting to make less projection errors than their less-complex counterparts. These results suggest that MA is a determinant that affects the accuracy of environmental capital expenditure projections for the firms in the ESI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=managerial%20ability" title="managerial ability">managerial ability</a>, <a href="https://publications.waset.org/abstracts/search?q=environmentally%20sensitive%20industries" title=" environmentally sensitive industries"> environmentally sensitive industries</a>, <a href="https://publications.waset.org/abstracts/search?q=sox" title=" sox"> sox</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20operational%20complexity" title=" corporate operational complexity"> corporate operational complexity</a> </p> <a href="https://publications.waset.org/abstracts/164383/the-impact-of-major-accounting-events-on-managerial-ability-and-the-accuracy-of-environmental-capital-expenditure-projections-of-the-environmentally-sensitive-industries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164383.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">145</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> Fan-Subbing in East Asia: Audience Involvement in Transnational Media Flows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20D.%20Lin">Jason D.

Situated in interdisciplinary academic work from cultural studies, media studies, and linguistics, this project locates the significance of certain genres and regions in determining why some are subject to flow while others remain within domestic borders. Moreover, transnational flows can take one of two routes –official translations and adaptations by media corporations and subtitles written by fans in online communities. The work of 'fan-subbing' has allowed for a more democratized showcase of what bilingual fans consume and are invested in sharing, rather than what major media companies deem relevant and monetizable. This reflects a culture of relatability driven by audiences rather than by corporate direction. Of course, a variety of technological, political, and economic factors play imperative roles in how both professional and fan-made subtitles flowed across borders and between nations. While fan-subbed media may be subject to criticism because of a lack of formal regulation, these limitations can, in some cases, be overcome by the agency afforded to audiences in the digital landscape. Finally, this paper offers a critical lens for deliberating the lasting impact of fan involvement on both professional practices and the flows of mainstream media throughout East Asia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audience%20studies" title="audience studies">audience studies</a>, <a href="https://publications.waset.org/abstracts/search?q=bilingual" title=" bilingual"> bilingual</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20proximity" title=" cultural proximity"> cultural proximity</a>, <a href="https://publications.waset.org/abstracts/search?q=fan-subbing" title=" fan-subbing"> fan-subbing</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20communities" title=" online communities"> online communities</a>, <a href="https://publications.waset.org/abstracts/search?q=subtitles" title=" subtitles"> subtitles</a> </p> <a href="https://publications.waset.org/abstracts/102976/fan-subbing-in-east-asia-audience-involvement-in-transnational-media-flows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102976.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">129</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> Particle Size Dependent Enhancement of Compressive Strength and Carbonation Efficiency in Steel Slag Cementitious Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20Ting%20Jing%20Cheng">Jason Ting Jing Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Foo%20Wei"> Lee Foo Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Yew%20Ming%20Kun"> Yew Ming Kun</a>, <a href="https://publications.waset.org/abstracts/search?q=Chin%20Ren%20Jie"> Chin Ren Jie</a>, <a href="https://publications.waset.org/abstracts/search?q=Yip%20Chun%20Chieh"> Yip Chun Chieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The utilization of industrial by-products, such as steel slag in cementitious materials, not only mitigates environmental impact but also enhances material properties. This study investigates the dual influence of steel slag particle size on the compressive strength and carbonation efficiency of cementitious composites. Through a systematic experimental approach, steel slag particles were incorporated into cement at varying sizes, and the resulting composites were subjected to mechanical and carbonation tests. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) are conducted in this paper. The findings reveal a positive correlation between increased particle size and compressive strength, attributed to the improved interfacial transition zone and packing density. Conversely, smaller particle sizes exhibited enhanced carbonation efficiency, likely due to the increased surface area facilitating the carbonation reaction. The presence of higher silica and calcium content in finer particles was confirmed by EDX, which contributed to the accelerated carbonation process. This study underscores the importance of particle size optimization in designing sustainable cementitious materials with balanced mechanical performance and carbon sequestration potential. The insights gained from the advanced analytical techniques offer a comprehensive understanding of the mechanisms at play, paving the way for the strategic use of steel slag in eco-friendly construction practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel%20slag" title="steel slag">steel slag</a>, <a href="https://publications.waset.org/abstracts/search?q=carbonation%20efficiency" title=" carbonation efficiency"> carbonation efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size%20enhancement" title=" particle size enhancement"> particle size enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/183245/particle-size-dependent-enhancement-of-compressive-strength-and-carbonation-efficiency-in-steel-slag-cementitious-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183245.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">61</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">51</span> The Proximate Composition and Phytochemical Screening of Momordica Balsamina (Balsam Apple) Fruit and Leaves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Viruska%20Jaichand">Viruska Jaichand</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Jason%20Mellem"> John Jason Mellem</a>, <a href="https://publications.waset.org/abstracts/search?q=Viresh%20Mohanlall"> Viresh Mohanlall</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Malnutrition is a global issue that affects both children and adults, irrespective of their socio-economic status. It is, therefore, important to find various means to tackle malnutrition. This is especially important as undernutrition and overnutrition can be linked to a variety of non-communicable diseases (NCDs). This study aimed to gather more insight into the nutritional and phytochemical quality of Momordica balsamina leaves and fruit (fruit pericarp, fruit flesh and seeds). Results showed that Momordica balsamina had a nutritional composition that would be advantageous to the human diet. The nutritional quality is verified by the presence of a high protein percentage across all samples (19.72%-29.08%), with the leaves containing the highest protein content (29.08%±0.77). There was also a low-fat content present across all samples, which ranged from 1.03% to 2.40%. The ash content indicated the presence of total minerals to be adequate (2.93%-21.16%), where the pericarp had the highest ash quantity (21.16%±0.09). The moisture levels were low (7.11%-13.40%). Momordica balsamina seeds had the highest carbohydrate content (67.84%±0.30). Rich in the major phytoconstituents, Momordica balsamina extracts were found to contain alkaloids, saponins, cardiac glycosides, steroids and triterpenoids. Based on these findings, it can thus be said that the incorporation of Momordica balsamina into an individual’s diet could prevent diseases associated with malnutrition, as well as it could be used to supplement the human diet in managing certain NCDs. Even though there were a number of bioactive compounds detected, further studies which would correlate the phytochemical constituents detected in Momordica balsamina and its effectiveness in treating various diseases are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=momordica%20balsamina" title="momordica balsamina">momordica balsamina</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrients" title=" nutrients"> nutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=proximate%20composition" title=" proximate composition"> proximate composition</a>, <a href="https://publications.waset.org/abstracts/search?q=bioactive%20compounds" title=" bioactive compounds"> bioactive compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoconstituents" title=" phytoconstituents"> phytoconstituents</a> </p> <a href="https://publications.waset.org/abstracts/173410/the-proximate-composition-and-phytochemical-screening-of-momordica-balsamina-balsam-apple-fruit-and-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173410.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">74</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> Nanoparticle Emission Characteristics during Methane Pyrolysis in a Laminar Premixed Flame</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Javad%20Afroughi">Mohammad Javad Afroughi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farjad%20Falahati"> Farjad Falahati</a>, <a href="https://publications.waset.org/abstracts/search?q=Larry%20W.%20Kostiuk"> Larry W.

An inverted burner is designed to provide a laminar premixed propane-air flame (35 SLPM) then introduce methane co-flow to be pyrolyzed within a closed cylindrical chamber (20 cm in diameter and 68 cm in length). The formed products are discharged through an exhaust with a sampling branch to measure emission characteristics. Carbon particles are sampled with a preheated nitrogen dilution system, and the size distribution of particles formed by pyrolysis is measured by a scanning mobility particle sizer (SMPS). Dilution ratio is calculated using simultaneously measured CO2 concentrations in the exhaust products and diluted samples. Results show that particle size distribution (PSD) is strongly affected by dilution ratio and preheating temperature. PSD becomes unstable at high dilution ratios (typically above 700 times) and/or low preheating temperatures (below 40° C). At a suitable dilution ratio of 55 and preheating temperature up to 70° C, the median diameter of PSD increases from 20 to 220 nm following the introduction of 0.5 SLPM of methane to the propane-air premixed flame. Furthermore, with pyrolysis of methane, total particle number concentration and estimated total mass concentration of particles in the size range of 14 to 700 nm, increase from 1.12 to 3.90 *107 cm-3 and from 0.11 to 154 µg L-1, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laminar%20premixed%20flame" title="laminar premixed flame">laminar premixed flame</a>, <a href="https://publications.waset.org/abstracts/search?q=methane%20pyrolysis" title=" methane pyrolysis"> methane pyrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle%20physical%20characteristics" title=" nanoparticle physical characteristics"> nanoparticle physical characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20mass%20concentration" title=" particle mass concentration"> particle mass concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20number%20concentration" title=" particle number concentration"> particle number concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size%20distribution%20%28PSD%29" title=" particle size distribution (PSD)"> particle size distribution (PSD)</a> </p> <a href="https://publications.waset.org/abstracts/77141/nanoparticle-emission-characteristics-during-methane-pyrolysis-in-a-laminar-premixed-flame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77141.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">238</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> Nuclear Mitochondrial Pseudogenes in Anastrepha fraterculus Complex</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pratibha%20Srivastava">Pratibha Srivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayyamperumal%20Jeyaprakash"> Ayyamperumal Jeyaprakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Gary%20Steck"> Gary Steck</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Stanley"> Jason Stanley</a>, <a href="https://publications.waset.org/abstracts/search?q=Leroy%20Whilby"> Leroy Whilby</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exotic, invasive tephritid fruit flies (Diptera: Tephritidae) are a major threat to fruit and vegetable industries in the United States. The establishment of pest fruit fly in the agricultural industries and produce severe ecological and economic impacts on agricultural diversification and trade. Detection and identification of these agricultural pests in a timely manner will facilitate the possibility of eradication from newly invaded areas. Identification of larval stages to species level is difficult, but is required to determine pest loads and their pathways into the United States. The aim of this study is the New World genus, Anastrepha which includes pests of major economic importance. Mitochondrial cytochrome c oxidase I (COI) gene sequences were amplified from Anastrepha fraterculus specimens collected from South America (Ecuador and Peru). Phylogenetic analysis was performed to characterize the Anastrepha fraterculus complex at a molecular level. During phylogenetics analysis numerous nuclear mitochondrial pseudogenes (numts) were discovered in different specimens. The numts are nonfunctional copies of the mtDNA present in the nucleus and are easily coamplified with the mitochondrial COI gene copy by using conserved universal primers. This is problematic for DNA Barcoding, which attempts to characterize all living organisms by using the COI gene. This study is significant for national quarantine use, as morphological diagnostics to separate larvae of the various members remain poorly developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tephritid" title="tephritid">tephritid</a>, <a href="https://publications.waset.org/abstracts/search?q=Anastrepha%20fraterculus" title=" Anastrepha fraterculus"> Anastrepha fraterculus</a>, <a href="https://publications.waset.org/abstracts/search?q=COI" title=" COI"> COI</a>, <a href="https://publications.waset.org/abstracts/search?q=numts" title=" numts"> numts</a> </p> <a href="https://publications.waset.org/abstracts/66131/nuclear-mitochondrial-pseudogenes-in-anastrepha-fraterculus-complex" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66131.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">239</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> Visual Servoing for Quadrotor UAV Target Tracking: Effects of Target Information Sharing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jason%20R.%20King">Jason R.

Most previous work in the field assumes static or slow-moving, unpredictable targets. In this experiment, the target is assumed to be a friendly ground robot moving freely on a horizontal plane, which shares information with the UAV. This information includes velocity and acceleration information of the ground target to aid the quadrotor in its tracking task. The quadrotor is assumed to have a downward-facing camera which is fixed to the frame of the quadrotor. Only onboard sensing for the quadrotor is utilized for the experiment, with a VICON motion capture system in place used only to measure ground truth and evaluate the performance of the controller. The experimental platform consists of an ArDrone 2.0 and a Create Roomba, communicating using Robot Operating System (ROS). The addition of the target’s information is demonstrated to help the quadrotor in its tracking task using simulations of the dynamic model of a quadrotor in Matlab Simulink. A nested PID control loop is utilized for inner-loop control the quadrotor, similar to previous works at the Flight Systems and Controls Laboratory (FSC) at the University of Toronto Institute for Aerospace Studies (UTIAS). Experiments are performed with ground truth provided by an indoor motion capture system, and the results are analyzed. It is demonstrated that a velocity controller which incorporates the additional information is able to perform better than the controllers which do not have access to the target’s information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quadrotor" title="quadrotor">quadrotor</a>, <a href="https://publications.waset.org/abstracts/search?q=target%20tracking" title=" target tracking"> target tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicle" title=" unmanned aerial vehicle"> unmanned aerial vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=UAV" title=" UAV"> UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=UAS" title=" UAS"> UAS</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20servoing" title=" visual servoing"> visual servoing</a> </p> <a href="https://publications.waset.org/abstracts/56269/visual-servoing-for-quadrotor-uav-target-tracking-effects-of-target-information-sharing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56269.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">341</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> Comparison of Low Velocity Impact Test on Coir Fiber Reinforced Polyester Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Mendoza">Ricardo Mendoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Brice%C3%B1o"> Jason Briceño</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20F.%20Santa"> Juan F.

In fact, composites components experience impact events in normal operations such as when a tool drops or a foreign object strikes it. These events are categorized into low velocity impact (LVI) which typically occurs at velocities below 10m/s. In this study, the major aim was to calculate the absorbed energy during the impact. Tests were performed on three types of composite panels: fiberglass laminated panels, coir fiber reinforced polyester and coir fiber reinforced polyester subjected to water immersion for 48 hours. Coir fibers were obtained in local plantations of the Caribbean coast of Colombia. They were alkali treated in 5% aqueous NaOH solution for 2h periods. Three type of shape impactors were used on drop-weight impact test including hemispherical, ogive and pointed. Failure mechanisms and failure modes of specimens were examined using an optical microscope. Results demonstrate a reduction in absorbed energy correlated with the increment of water absorption of the panels. For each level of absorbed energy, it was possible to associate a different fracture state. This study compares results of energy absorbed obtained from two impact test methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coir%20fiber" title="coir fiber">coir fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=polyester%20composites" title=" polyester composites"> polyester composites</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20velocity%20impact" title=" low velocity impact"> low velocity impact</a>, <a href="https://publications.waset.org/abstracts/search?q=Charpy%20impact%20test" title=" Charpy impact test"> Charpy impact test</a>, <a href="https://publications.waset.org/abstracts/search?q=drop-weight%20impact%20test" title=" drop-weight impact test"> drop-weight impact test</a> </p> <a href="https://publications.waset.org/abstracts/55674/comparison-of-low-velocity-impact-test-on-coir-fiber-reinforced-polyester-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55674.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">452</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> Planktivorous Fish Schooling Responses to Current at Natural and Artificial Reefs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthew%20Holland">Matthew Holland</a>, <a href="https://publications.waset.org/abstracts/search?q=Jason%20Everett"> Jason Everett</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Cox"> Martin Cox</a>, <a href="https://publications.waset.org/abstracts/search?q=Iain%20Suthers"> Iain Suthers</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High spatial-resolution distribution of planktivorous reef fish can reveal behavioural adaptations to optimise the balance between feeding success and predator avoidance. We used a multi-beam echosounder to record bathymetry and the three-dimensional distribution of fish schools associated with natural and artificial reefs. We utilised generalised linear models to assess the distribution, orientation, and aggregation of fish schools relative to the structure, vertical relief, and currents. At artificial reefs, fish schooled more closely to the structure and demonstrated a preference for the windward side, particularly when exposed to strong currents. Similarly, at natural reefs fish demonstrated a preference for windward aspects of bathymetry, particularly when associated with high vertical relief. Our findings suggest that under conditions with stronger current velocity, fish can exercise their preference to remain close to structure for predator avoidance, while still receiving an adequate supply of zooplankton delivered by the current. Similarly, when current velocity is low, fish tend to disperse for better access to zooplankton. As artificial reefs are generally deployed with the goal of creating productivity rather than simply attracting fish from elsewhere, we advise that future artificial reefs be designed as semi-linear arrays perpendicular to the prevailing current, with multiple tall towers. This will facilitate the conversion of dispersed zooplankton into energy for higher trophic levels, enhancing reef productivity and fisheries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20reef" title="artificial reef">artificial reef</a>, <a href="https://publications.waset.org/abstracts/search?q=current" title=" current"> current</a>, <a href="https://publications.waset.org/abstracts/search?q=forage%20fish" title=" forage fish"> forage fish</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-beam" title=" multi-beam"> multi-beam</a>, <a href="https://publications.waset.org/abstracts/search?q=planktivorous%20fish" title=" planktivorous fish"> planktivorous fish</a>, <a href="https://publications.waset.org/abstracts/search?q=reef%20fish" title=" reef fish"> reef fish</a>, <a href="https://publications.waset.org/abstracts/search?q=schooling" title=" schooling"> schooling</a> </p> <a href="https://publications.waset.org/abstracts/110547/planktivorous-fish-schooling-responses-to-current-at-natural-and-artificial-reefs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110547.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Application of a Series of New Platinum Organometallic Complexes Derived from Bidentate Schiff Base Ligands in the Hydrogenative and Dehydrogenative Silylation of Styrene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Belhadj%20Lachachi">M.

Advances in organometallic chemistry are crucial for improving the design of compounds to reduce toxic side effects and understand their mechanisms of action. The reaction of platinum(II) organometallic complexes with bidentate Schiff bases derived from 2-Hydroxynaphtalydeneaniline have been carried out. It concerns N,N’-naphtalidene para-nitroaniline (1-a), the, the N,N’-naphtalidene para-ethoxyaniline (1-b), the N,N’-naphtalideneaniline (1-c), the N,N’-naphtalidene para-chloroaniline (1-d) and the N,N’-naphtalidene para-methoxyaniline (1-e). The ligands were fully characterized by I.R., elemental analysis, 1H-NMR, 13C-NMR, ESI Mass Spectrometry and X-Ray Diffraction. The resulting metal complexes were obtained as a cationic species, through a simple substitution reaction, leading to two geometric isomers [1, 2], and characterized by IR, 1H-NMR, 13C-NMR, LIFDI Mass Spectrometry and supported by Elemental Analysis and X-Ray diffraction. Furthermore, a bimetallic platinum complex was prepared from the same ligands and dichloro(1,5-cyclooctadiene)platinum and characterized by X-Ray diffraction [3]The catalytic properties of the prepared platinum complexes in the hydrogenative and dehydrogenative silylation of styrene were investigated, and reaction kinetics conversion to products was determined by 1H-NMR and confirmed by GC-MS. This presentation will detail a comparison of the catalytic activity of five platinum organometallic complexes bearing different Schiff base ligands in the hydrosilylation of styrene, varying the experimental conditions of temperature, nature of the complex and the loading of the catalyst. <p class="card-text"><strong>Keywords:</strong> <a
