Each member of the proposed family requires two evaluations of the given function and two evaluations of the first-order derivative per iteration. By using Mathematica-9 with its high precision compatibility, a variety of concrete numerical experiments and relevant results are extensively treated to confirm t he t heoretical d evelopment. From their basins of attraction, it has been observed that the proposed methods have better stability and robustness as compared to the other sixth-order methods available in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basins%20of%20attraction" title="basins of attraction">basins of attraction</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20equations" title=" nonlinear equations"> nonlinear equations</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20roots" title=" simple roots"> simple roots</a>, <a href="https://publications.waset.org/abstracts/search?q=super-Halley" title=" super-Halley"> super-Halley</a> </p> <a href="https://publications.waset.org/abstracts/29042/sixth-order-two-point-efficient-family-of-super-halley-type-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29042.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">518</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">14</span> Wave State of Self: Findings of Synchronistic Patterns in the Collective Unconscious </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Dimitri%20Halley">R. Dimitri Halley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research within Jungian Psychology presented here is on the wave state of Self. What has been discovered via shared dreaming, independently correlating dreams across dreamers, is beyond the Self stage into the deepest layer or the wave state Self: the very quantum ocean, the Self archetype is embedded in. A quantum wave or rhyming of meaning constituting synergy across several dreamers was discovered in dreams and in extensively shared dream work with small groups at a post therapy stage. Within the format of shared dreaming, we find synergy patterns beyond what Jung called the Self archetype. Jung led us up to the phase of Individuation and delivered the baton to Von Franz to work out the next synchronistic stage, here proposed as the finding of the quantum patterns making up the wave state of Self. These enfolded synchronistic patterns have been found in group format of shared dreaming of individuals approximating individuation, and the unfolding of it is carried by belief and faith. The reason for this format and operating system is because beyond therapy and of living reality, we find no science – no thinking or even awareness in the therapeutic sense – but rather a state of mental processing resembling more like that of spiritual attitude. Thinking as such is linear and cannot contain the deepest layer of Self, the quantum core of the human being. It is self reflection which is the container for the process at the wave state of Self. Observation locks us in an outside-in reactive flow from a first-person perspective and hence toward the surface we see to believe, whereas here, the direction of focus shifts to inside out/intrinsic. The operating system or language at the wave level of Self is thus belief and synchronicity. Belief has up to now been almost the sole province of organized religions but was viewed by Jung as an inherent property in the process of Individuation. The shared dreaming stage of the synchronistic patterns forms a larger story constituting a deep connectivity unfolding around individual Selves. Dreams of independent dreamers form larger patterns that come together as puzzles forming a larger story, and in this sense, this group work level builds on Jung as a post individuation collective stage. Shared dream correlations will be presented, illustrating a larger story in terms of trails of shared synchronicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=belief" title="belief">belief</a>, <a href="https://publications.waset.org/abstracts/search?q=shared%20dreaming" title=" shared dreaming"> shared dreaming</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronistic%20patterns" title=" synchronistic patterns"> synchronistic patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20state%20of%20self" title=" wave state of self"> wave state of self</a> </p> <a href="https://publications.waset.org/abstracts/117637/wave-state-of-self-findings-of-synchronistic-patterns-in-the-collective-unconscious" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117637.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">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Upon One Smoothing Problem in Project Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitri%20Golenko-Ginzburg">Dimitri Golenko-Ginzburg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A CPM network project with deterministic activity durations, in which activities require homogenous resources with fixed capacities, is considered. The problem is to determine the optimal schedule of starting times for all network activities within their maximal allowable limits (in order not to exceed the network's critical time) to minimize the maximum required resources for the project at any point in time. In case when a non-critical activity may start only at discrete moments with the pregiven time span, the problem becomes NP-complete and an optimal solution may be obtained via a look-over algorithm. For the case when a look-over requires much computational time an approximate algorithm is suggested. The algorithm's performance ratio, i.e., the relative accuracy error, is determined. Experimentation has been undertaken to verify the suggested algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resource%20smoothing%20problem" title="resource smoothing problem">resource smoothing problem</a>, <a href="https://publications.waset.org/abstracts/search?q=CPM%20network" title=" CPM network"> CPM network</a>, <a href="https://publications.waset.org/abstracts/search?q=lookover%20algorithm" title=" lookover algorithm"> lookover algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=lexicographical%20order" title=" lexicographical order"> lexicographical order</a>, <a href="https://publications.waset.org/abstracts/search?q=approximate%20algorithm" title=" approximate algorithm"> approximate algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=accuracy%20estimate" title=" accuracy estimate"> accuracy estimate</a> </p> <a href="https://publications.waset.org/abstracts/15779/upon-one-smoothing-problem-in-project-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15779.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">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Holistic Risk Assessment Based on Continuous Data from the User’s Behavior and Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cinzia%20Carrodano">Cinzia Carrodano</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitri%20Konstantas"> Dimitri Konstantas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Risk is part of our lives. In today’s society risk is connected to our safety and safety has become a major priority in our life. Each person lives his/her life based on the evaluation of the risk he/she is ready to accept and sustain, and the level of safety he/she wishes to reach, based on highly personal criteria. The assessment of risk a person takes in a complex environment and the impact of actions of other people’actions and events on our perception of risk are alements to be considered. The concept of Holistic Risk Assessment (HRA) aims in developing a methodology and a model that will allow us to take into account elements outside the direct influence of the individual, and provide a personalized risk assessment. The concept is based on the fact that in the near future, we will be able to gather and process extremely large amounts of data about an individual and his/her environment in real time. The interaction and correlation of these data is the key element of the holistic risk assessment. In this paper, we present the HRA concept and describe the most important elements and considerations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20data" title="continuous data">continuous data</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20risk" title=" dynamic risk"> dynamic risk</a>, <a href="https://publications.waset.org/abstracts/search?q=holistic%20risk%20assessment" title=" holistic risk assessment"> holistic risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20concept" title=" risk concept"> risk concept</a> </p> <a href="https://publications.waset.org/abstracts/145051/holistic-risk-assessment-based-on-continuous-data-from-the-users-behavior-and-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145051.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Procedure for Impact Testing of Fused Recycled Glass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Halley">David Halley</a>, <a href="https://publications.waset.org/abstracts/search?q=Tyra%20Oseng-Rees"> Tyra Oseng-Rees</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Pagano"> Luca Pagano</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20A%20Ferriz-Papi"> Juan A Ferriz-Papi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recycled glass material is made from 100% recycled bottle glass and consumes less energy than re-melt technology. It also uses no additives in the manufacturing process allowing the recycled glass material, in principal, to go back to the recycling stream after end-of-use, contributing to the circular economy with a low ecological impact. The aim of this paper is to investigate the procedure for testing the recycled glass material for impact resistance, so it can be applied to pavements and other surfaces which are at risk of impact during service. A review of different impact test procedures for construction materials was undertaken, comparing methodologies and international standards applied to other materials such as natural stone, ceramics and glass. A drop weight impact testing machine was designed and manufactured in-house to perform these tests. As a case study, samples of the recycled glass material were manufactured with two different thicknesses and tested. The impact energy was calculated theoretically, obtaining results with 5 and 10 J. The results on the material were subsequently discussed. Improvements on the procedure can be made using high speed video technology to calculate velocity just before and immediately after the impact to know the absorbed energy. The initial results obtained in this procedure were positive although repeatability needs to be developed to obtain a correlation of results and finally be able to validate the procedure. The experiment with samples showed the practicality of this procedure and application to the recycled glass material impact testing although further research needs to be developed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20materials" title="construction materials">construction materials</a>, <a href="https://publications.waset.org/abstracts/search?q=drop%20weight%20impact" title=" drop weight impact"> drop weight impact</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20testing" title=" impact testing"> impact testing</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20glass" title=" recycled glass"> recycled glass</a> </p> <a href="https://publications.waset.org/abstracts/79723/procedure-for-impact-testing-of-fused-recycled-glass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79723.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">296</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Influence of the Paint Coating Thickness in Digital Image Correlation Experiments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20A.%20P%C3%A9rez">Jesús A.

This non-contact tool enables full field displacement and strain measurements over a complete region of interest. The DIC algorithm requires a random contrast pattern on the surface of the specimen in order to perform properly. To create this pattern, the specimen is usually first coated using a white matt paint. Next, a black random speckle pattern is applied using any suitable method. If the applied paint coating is too thick, its top surface may not be able to exactly follow the deformation of the specimen, and consequently, the strain measurement might be underestimated. In the present article, a study of the influence of the paint thickness on the strain underestimation is performed for different strain levels. The results are then compared to typical paint coating thicknesses applied by experienced DIC users. A slight strain underestimation was observed for paint coatings thicker than about 30μm. On the other hand, this value was found to be uncommonly high compared to coating thicknesses applied by DIC users. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20image%20correlation" title="digital image correlation">digital image correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=paint%20coating%20thickness" title=" paint coating thickness"> paint coating thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=strain" title=" strain"> strain</a> </p> <a href="https://publications.waset.org/abstracts/26162/influence-of-the-paint-coating-thickness-in-digital-image-correlation-experiments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26162.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">515</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Non-Monogamy as Rebellion against Tradition in Jhumpa Lahiri’s The Namesake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingya%20Huang">Jingya Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper argues that Moushumi Mazoomdar has non-monogamous relationships with different men before and after her marriage as a form of rebellion against the traditional Indian culture deeply ingrained in her. Written by Jhumpa Lahiri, The Namesake (2004) features an Indian couple migrating to America who gives birth to two children, including the main character Gogol. Moushumi, like Gogol, is also a second-generation Indian American. Because of the influence of American culture, Moushumi prefers to marry for love, disdaining any thought of an arranged marriage. This paper is divided into two parts: before and after marriage which can also be seen in the light of polyamory and infidelity. First, according to Anapol (2010), polyamory is a newly created word from Greek and Latin which means “loving more than one person at a time when it comes to romantic or erotic love.” The discussion of polyamory mainly focuses on the most basic heterosexual relationship without mentioning of homosexual and bisexual love relationships. By adopting Anapol’s concept of polyamory, this paper examines the nature of the relationships between Moushumi and other men before her marriage. Afterwards, the concept of infidelity is discussed to analyze the interaction between Moushumi and Dimitri. How Moushumi rebels against tradition is shown through these two main discussions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indian%20American" title="Indian American">Indian American</a>, <a href="https://publications.waset.org/abstracts/search?q=non-monogamous%20relationship" title=" non-monogamous relationship"> non-monogamous relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=rebellion" title=" rebellion"> rebellion</a>, <a href="https://publications.waset.org/abstracts/search?q=polyamory" title=" polyamory"> polyamory</a>, <a href="https://publications.waset.org/abstracts/search?q=infidelity" title=" infidelity"> infidelity</a> </p> <a href="https://publications.waset.org/abstracts/14844/non-monogamy-as-rebellion-against-tradition-in-jhumpa-lahiris-the-namesake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14844.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">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> 'Utopian Performatives' for Peace: A Radical Approach to Evaluating the Value of Documentary Theatre in Northern Ireland</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harry%20Mccallum">Harry Mccallum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last decade, there has been an upsurge in documentary theatre projects that seek to address issues arising from ‘the Troubles’ by theatre and community organisations such as The Playhouse, Kabosh, and The Verbal Arts Centre. This movement has been supported by a variety of funding agencies who have identified the importance of the instrumental use of theatre for generating societal development. However, with this upsurge in interest comes complications surrounding the subjectivity of evaluations and an understanding of their empirical impact on society. This largely theoretical led-discussion promotes the engagement of Jill Dolan’s ‘utopian performatives’ (2005) within the remit of documentary theatre for peacebuilding practices in Northern Ireland.‘Utopian Performatives’ are described as being profound moments in a theatre production that transforms audience members into a state of ‘hopeful feeling’.As a concept, they are situated within the discourse surrounding audience reception and the ‘affective turn’ (Brennan, 2004; Clough and Halley, 2007; Ahmed, 2014), which indicates its persistence on a short-term ephemeral outlook. It is therefore important to understand how this short-term ‘affect’ can expand into a longer-term ‘effect.’ Through this interdisciplinary study between ‘peace’ and ‘theatre’ studies, I am proposinga theoretical framework that examines how these individual ‘utopian performatives’ at the personal level can lead to a change at the societal level. The framework understands that ‘utopian performatives’ have the capacity to generate discussion and empower audience members to actively strive for a ‘positive peace’; something which is evidently absent in a contemporary Northern Ireland. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=theatre" title="theatre">theatre</a>, <a href="https://publications.waset.org/abstracts/search?q=peacebuilding" title=" peacebuilding"> peacebuilding</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict%20transformation" title=" conflict transformation"> conflict transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=northern%20Ireland" title=" northern Ireland"> northern Ireland</a> </p> <a href="https://publications.waset.org/abstracts/144391/utopian-performatives-for-peace-a-radical-approach-to-evaluating-the-value-of-documentary-theatre-in-northern-ireland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144391.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">7</span> A Biomechanical Perfusion System for Microfluidic 3D Bioprinted Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Dimitri">M.

The microperfusion system was developed to provide a constant and controlled flow of nutrients and oxygen through the integrated vessels in the bioconstruct, replicating in vivo physiological conditions. Through a series of preliminary experiments, we evaluated the system's ability to maintain a favorable environment for cell proliferation and differentiation. Measurements of cell density and viability were performed to monitor the health and functionality of the tissue over time. Preliminary results indicate that the portable microperfusion system not only supports but optimizes cell growth, effectively adapting to changes in metabolic needs during the bioconstruct maturation process. This research opens perspectives in tissue engineering, demonstrating that a portable microperfusion system can be successfully integrated into 3D-printed bioconstructs, promoting sustainable and uniform cell growth. The implications of this study are far-reaching, with potential applications in regenerative medicine and pharmacological research, providing a platform for the development of functional and complex tissues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofabrication" title="biofabrication">biofabrication</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidic%20perfusion%20system" title=" microfluidic perfusion system"> microfluidic perfusion system</a>, <a href="https://publications.waset.org/abstracts/search?q=4D%20bioprinting" title=" 4D bioprinting"> 4D bioprinting</a> </p> <a href="https://publications.waset.org/abstracts/189002/a-biomechanical-perfusion-system-for-microfluidic-3d-bioprinted-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189002.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">30</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">6</span> Experimental Set-up for the Thermo-Hydric Study of a Wood Chips Bed Crossed by an Air Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitri%20Bigot">Dimitri Bigot</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Malet-Damour"> Bruno Malet-Damour</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%A9r%C3%B4me%20Vigneron"> Jérôme Vigneron</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many studies have been made about using bio-based materials in buildings. The goal is to reduce its environmental footprint by analyzing its life cycle. This can lead to minimize the carbon emissions or energy consumption. A previous work proposed to numerically study the feasibility of using wood chips to regulate relative humidity inside a building. This has shown the capability of a wood chips bed to regulate humidity inside the building, to improve thermal comfort, and so potentially reduce building energy consumption. However, it also shown that some physical parameters of the wood chips must be identified to validate the proposed model and the associated results. This paper presents an experimental setup able to study such a wood chips bed with different solicitations. It consists of a simple duct filled with wood chips and crossed by an air flow with variable temperature and relative humidity. Its main objective is to study the thermal behavior of the wood chips bed by controlling temperature and relative humidity of the air that enters into it and by observing the same parameters at the output. First, the experimental set up is described according to previous results. A focus is made on the particular properties that have to be characterized. Then some case studies are presented in relation to the previous results in order to identify the key physical properties. Finally, the feasibility of the proposed technology is discussed, and some model validation paths are given. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20chips%20bed" title="wood chips bed">wood chips bed</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20set-up" title=" experimental set-up"> experimental set-up</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-based%20%20material" title=" bio-based material"> bio-based material</a>, <a href="https://publications.waset.org/abstracts/search?q=desiccant" title=" desiccant"> desiccant</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20humidity" title=" relative humidity"> relative humidity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20content" title=" water content"> water content</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20behaviour" title=" thermal behaviour"> thermal behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20treatment" title=" air treatment"> air treatment</a> </p> <a href="https://publications.waset.org/abstracts/139654/experimental-set-up-for-the-thermo-hydric-study-of-a-wood-chips-bed-crossed-by-an-air-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139654.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">5</span> Psychological Distress Screening in Patients with Esophageal Cancer after Esophagectomy: A Scoping Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erietta-Christina%20Arnaoutaki">Erietta-Christina Arnaoutaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Stelios-Elion%20Bousi"> Stelios-Elion Bousi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marinos%20Zachiotis"> Marinos Zachiotis</a>, <a href="https://publications.waset.org/abstracts/search?q=Simoni%20Zarkada"> Simoni Zarkada</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandra%20Chrysagi"> Alexandra Chrysagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamdouh%20Fahad%20Alenazi"> Mamdouh Fahad Alenazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitri%20Aristotle%20Raptis"> Dimitri Aristotle Raptis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: This review aimed to evaluate the mental health status of patients with esophageal cancer following surgical treatment, as well as the role of psychological distress screening tests in this patient population. Methods: Studies reporting psychometric screening tools used in esophageal cancer patients after esophagectomy, published before January 2024 on PubMed, Scopus, and CENTRAL databases, were searched and analyzed. Results: Six non-randomized control trials were selected for inclusion in this scoping review, which involved 1059 patients undergoing esophagectomy for esophageal cancer. Among the included studies, five employed the Hospital Anxiety and Depression Scale (HADS) for anxiety and/or depression screening, while one used the MD Anderson Symptom Inventory for gastrointestinal cancer (MDASI-GI) for sadness screening. A range of time points was used to evaluate these patients: 102 patients were evaluated at 1 month, 230 patients at 3 months, 218 patients at 6 months, 653 patients at 12 months, and 154 patients at 24 months postoperatively. Analysis of data pooled from three studies employing the HADS revealed a prevalence of 19.45% for anxiety and 17.92% for depression at the 12-month follow-up and mean scores of 3.91 (3.12) and 3.56 (3.12) for the HADS anxiety (HADS-A) and depression (HADS-D) subscales respectively, at any time postoperatively. Conclusion: The findings show a neglected concern regarding the mental health of esophageal cancer survivors following surgical treatment. The use of psychometric screening tools is essential to address psychological distress and improve the quality of life of these patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=esophageal%20cancer" title="esophageal cancer">esophageal cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=esophagectomy" title=" esophagectomy"> esophagectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20distress" title=" psychological distress"> psychological distress</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=psychometric%20tests" title=" psychometric tests"> psychometric tests</a>, <a href="https://publications.waset.org/abstracts/search?q=HADS" title=" HADS"> HADS</a>, <a href="https://publications.waset.org/abstracts/search?q=MDASI-GI" title=" MDASI-GI"> MDASI-GI</a> </p> <a href="https://publications.waset.org/abstracts/193196/psychological-distress-screening-in-patients-with-esophageal-cancer-after-esophagectomy-a-scoping-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193196.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">18</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">4</span> Epidemiology of Congenital Heart Defects in Kazakhstan: Data from Unified National Electronic Healthcare System 2014-2020</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dmitriy%20Syssoyev">Dmitriy Syssoyev</a>, <a href="https://publications.waset.org/abstracts/search?q=Aslan%20Seitkamzin"> Aslan Seitkamzin</a>, <a href="https://publications.waset.org/abstracts/search?q=Natalya%20Lim"> Natalya Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamilla%20Mussina"> Kamilla Mussina</a>, <a href="https://publications.waset.org/abstracts/search?q=Abduzhappar%20Gaipov"> Abduzhappar Gaipov</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitri%20Poddighe"> Dimitri Poddighe</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinara%20Galiyeva"> Dinara Galiyeva</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Data on the epidemiology of congenital heart defects (CHD) in Kazakhstan is scarce. Therefore, the aim of this study was to describe the incidence, prevalence and all-cause mortality of patients with CHD in Kazakhstan, using national large-scale registry data from the Unified National Electronic Healthcare System (UNEHS) for the period of 2014-2020. Methods: In this retrospective cohort study, the included data pertained to all patients diagnosed with CHD in Kazakhstan and registered in UNEHS between January 2014 and December 2020. CHD was defined based on International Classification of Diseases 10th Revision (ICD-10) codes Q20-Q26. Incidence, prevalence, and all-cause mortality rates were calculated per 100,000 population. Survival analysis was performed using Cox proportional hazards regression modeling and the Kaplan-Meier method. Results: In total, 66,512 patients were identified. Among them, 59,534 (89.5%) were diagnosed with a single CHD, while 6,978 (10.5%) had more than two CHDs. The median age at diagnosis was 0.08 years (interquartile range (IQR) 0.01 – 0.66) for people with multiple CHD types and 0.39 years (IQR 0.04 – 8.38) for those with a single CHD type. The most common CHD types were atrial septal defect (ASD) and ventricular septal defect (VSD), accounting for 25.8% and 21.2% of single CHD cases, respectively. The most common multiple types of CHD were ASD with VSD (23.4%), ASD with patent ductus arteriosus (PDA) (19.5%), and VSD with PDA (17.7%). The incidence rate of CHD decreased from 64.6 to 47.1 cases per 100,000 population among men and from 68.7 to 42.4 among women. The prevalence rose from 66.1 to 334.1 cases per 100,000 population among men and from 70.8 to 328.7 among women. Mortality rates showed a slight increase from 3.5 to 4.7 deaths per 100,000 in men and from 2.9 to 3.7 in women. Median follow-up was 5.21 years (IQR 2.47 – 11.69). Male sex (HR 1.60, 95% CI 1.45 - 1.77), having multiple CHDs (HR 2.45, 95% CI 2.01 - 2.97), and living in a rural area (HR 1.32, 95% CI 1.19 - 1.47) were associated with a higher risk of all-cause mortality. Conclusion: The incidence of CHD in Kazakhstan has shown a moderate decrease between 2014 and 2020, while prevalence and mortality have increased. Male sex, multiple CHD types, and rural residence were significantly associated with a higher risk of all-cause mortality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=congenital%20heart%20defects%20%28CHD%29" title="congenital heart defects (CHD)">congenital heart defects (CHD)</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=incidence" title=" incidence"> incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazakhstan" title=" Kazakhstan"> Kazakhstan</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence" title=" prevalence"> prevalence</a> </p> <a href="https://publications.waset.org/abstracts/168297/epidemiology-of-congenital-heart-defects-in-kazakhstan-data-from-unified-national-electronic-healthcare-system-2014-2020" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168297.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Bundling of Transport Flows: Adoption Barriers and Opportunities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vandenbroucke%20Karel">Vandenbroucke Karel</a>, <a href="https://publications.waset.org/abstracts/search?q=Georges%20Annabel"> Georges Annabel</a>, <a href="https://publications.waset.org/abstracts/search?q=Schuurman%20Dimitri"> Schuurman Dimitri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the past years, bundling of transport flows, whether or not implemented in an intermodal process, has popped up as a promising concept in the logistics sector. Bundling of transport flows is a process where two or more shippers decide to synergize their shipped goods over a common transport lane. Promoted by the European Commission, several programs have been set up and have shown their benefits. Bundling promises both shippers and logistics service providers economic, societal and ecological benefits. By bundling transport flows and thus reducing truck (or other carrier) capacity, the problems of driver shortage, increased fuel prices, mileage charges and restricted hours of service on the road are solved. In theory, the advantages of bundled transport exceed the drawbacks, however, in practice adoption among shippers remains low. In fact, bundling is mentioned as a disruptive process in the rather traditional logistics sector. In this context, a Belgian company asked iMinds Living Labs to set up a Living Lab research project with the goal to investigate how the uptake of bundling transport flows can be accelerated and to check whether an online data sharing platform can overcome the adoption barriers. The Living Lab research was conducted in 2016 and combined quantitative and qualitative end-user and market research. Concretely, extensive desk research was conducted and combined with insights from expert interviews with four consultants active in the Belgian logistics sector and in-depth interviews with logistics professionals working for shippers (N=10) and LSP’s (N=3). In the article, we present findings which show that there are several factors slowing down the uptake of bundling transport flows. Shippers are hesitant to change how they currently work and they are hesitant to work together with other shippers. Moreover, several practical challenges impede shippers to work together. We also present some opportunities that can accelerate the adoption of bundling of transport flows. First, it seems that there is not enough support coming from governmental and commercial organizations. Secondly, there is the chicken and the egg problem: too few interested parties will lead to no or very few matching lanes. Shippers are therefore reluctant to partake in these projects because the benefits have not yet been proven. Thirdly, the incentive is not big enough for shippers. Road transport organized by the shipper individually is still seen as the easiest and cheapest solution. A solution for the abovementioned challenges might be found in the online data sharing platform of the Belgian company. The added value of this platform is showing shippers possible matching lanes, without the shippers having to invest time in negotiating and networking with other shippers and running the risk of not finding a match. The interviewed shippers and experts indicated that the online data sharing platform is a very promising concept which could accelerate the uptake of bundling of transport flows. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adoption%20barriers" title="adoption barriers">adoption barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=bundling%20of%20transport" title=" bundling of transport"> bundling of transport</a>, <a href="https://publications.waset.org/abstracts/search?q=shippers" title=" shippers"> shippers</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20optimization" title=" transport optimization"> transport optimization</a> </p> <a href="https://publications.waset.org/abstracts/59762/bundling-of-transport-flows-adoption-barriers-and-opportunities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59762.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">200</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Aerosol Characterization in a Coastal Urban Area in Rimini, Italy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitri%20Bacco">Dimitri Bacco</a>, <a href="https://publications.waset.org/abstracts/search?q=Arianna%20Trentini"> Arianna Trentini</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabiana%20Scotto"> Fabiana Scotto</a>, <a href="https://publications.waset.org/abstracts/search?q=Flavio%20Rovere"> Flavio Rovere</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Foscoli"> Daniele Foscoli</a>, <a href="https://publications.waset.org/abstracts/search?q=Cinzia%20Para"> Cinzia Para</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Veronesi"> Paolo Veronesi</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Sandrini"> Silvia Sandrini</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Zigola"> Claudia Zigola</a>, <a href="https://publications.waset.org/abstracts/search?q=Michela%20Comandini"> Michela Comandini</a>, <a href="https://publications.waset.org/abstracts/search?q=Marilena%20Montalti"> Marilena Montalti</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Zamagni"> Marco Zamagni</a>, <a href="https://publications.waset.org/abstracts/search?q=Vanes%20Poluzzi"> Vanes Poluzzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Po Valley, in the north of Italy, is one of the most polluted areas in Europe. The air quality of the area is linked not only to anthropic activities but also to its geographical characteristics and stagnant weather conditions with frequent inversions, especially in the cold season. Even the coastal areas present high values of particulate matter (PM10 and PM2.5) because the area closed between the Adriatic Sea and the Apennines does not favor the dispersion of air pollutants. The aim of the present work was to identify the main sources of particulate matter in Rimini, a tourist city in northern Italy. Two sampling campaigns were carried out in 2018, one in winter (60 days) and one in summer (30 days), in 4 sites: an urban background, a city hotspot, a suburban background, and a rural background. The samples are characterized by the concentration of the ionic composition of the particulates and of the main a hydro-sugars, in particular levoglucosan, a marker of the biomass burning, because one of the most important anthropogenic sources in the area, both in the winter and surprisingly even in the summer, is the biomass burning. Furthermore, three sampling points were chosen in order to maximize the contribution of a specific biomass source: a point in a residential area (domestic cooking and domestic heating), a point in the agricultural area (weed fires), and a point in the tourist area (restaurant cooking). In these sites, the analyzes were enriched with the quantification of the carbonaceous component (organic and elemental carbon) and with measurement of the particle number concentration and aerosol size distribution (6 - 600 nm). The results showed a very significant impact of the combustion of biomass due to domestic heating in the winter period, even though many intense peaks were found attributable to episodic wood fires. In the summer season, however, an appreciable signal was measured linked to the combustion of biomass, although much less intense than in winter, attributable to domestic cooking activities. Further interesting results were the verification of the total absence of sea salt's contribution in the particulate with the lower diameter (PM2.5), and while in the PM10, the contribution becomes appreciable only in particular wind conditions (high wind from north, north-east). Finally, it is interesting to note that in a small town, like Rimini, in summer, the traffic source seems to be even more relevant than that measured in a much larger city (Bologna) due to tourism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerosol" title="aerosol">aerosol</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20burning" title=" biomass burning"> biomass burning</a>, <a href="https://publications.waset.org/abstracts/search?q=seacoast" title=" seacoast"> seacoast</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20area" title=" urban area"> urban area</a> </p> <a href="https://publications.waset.org/abstracts/117769/aerosol-characterization-in-a-coastal-urban-area-in-rimini-italy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117769.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">128</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">1</span> Numerical Modeling of Phase Change Materials Walls under Reunion Island's Tropical Weather</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lionel%20Trovalet">Lionel Trovalet</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Liu"> Lisa Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitri%20Bigot"> Dimitri Bigot</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Hammami"> Nadia Hammami</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Pierre%20Habas"> Jean-Pierre Habas</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Malet-Damour"> Bruno Malet-Damour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The MCP-iBAT1 project is carried out to study the behavior of Phase Change Materials (PCM) integrated in building envelopes in a tropical environment. Through the phase transitions (melting and freezing) of the material, thermal energy can be absorbed or released. This process enables the regulation of indoor temperatures and the improvement of thermal comfort for the occupants. Most of the commercially available PCMs are more suitable to temperate climates than to tropical climates. The case of Reunion Island is noteworthy as there are multiple micro-climates. This leads to our key question: developing one or multiple bio-based PCMs that cover the thermal needs of the different locations of the island. The present paper focuses on the numerical approach to select the PCM properties relevant to tropical areas. Numerical simulations have been carried out with two softwares: EnergyPlusTM and Isolab. The latter has been developed in the laboratory, with the implicit Finite Difference Method, in order to evaluate different physical models. Both are Thermal Dynamic Simulation (TDS) softwares that predict the building’s thermal behavior with one-dimensional heat transfers. The parameters used in this study are the construction’s characteristics (dimensions and materials) and the environment’s description (meteorological data and building surroundings). The building is modeled in accordance with the experimental setup. It is divided into two rooms, cells A and B, with same dimensions. Cell A is the reference, while in cell B, a layer of commercial PCM (Thermo Confort of MCI Technologies) has been applied to the inner surface of the North wall. Sensors are installed in each room to retrieve temperatures, heat flows, and humidity rates. The collected data are used for the comparison with the numerical results. Our strategy is to implement two similar buildings at different altitudes (Saint-Pierre: 70m and Le Tampon: 520m) to measure different temperature ranges. Therefore, we are able to collect data for various seasons during a condensed time period. The following methodology is used to validate the numerical models: calibration of the thermal and PCM models in EnergyPlusTM and Isolab based on experimental measures, then numerical testing with a sensitivity analysis of the parameters to reach the targeted indoor temperatures. The calibration relies on the past ten months’ measures (from September 2020 to June 2021), with a focus on one-week study on November (beginning of summer) when the effect of PCM on inner surface temperatures is more visible. A first simulation with the PCM model of EnergyPlus gave results approaching the measurements with a mean error of 5%. The studied property in this paper is the melting temperature of the PCM. By determining the representative temperature of winter, summer and inter-seasons with past annual’s weather data, it is possible to build a numerical model of multi-layered PCM. Hence, the combined properties of the materials will provide an optimal scenario for the application on PCM in tropical areas. Future works will focus on the development of bio-based PCMs with the selected properties followed by experimental and numerical validation of the materials. 1Materiaux ´ a Changement de Phase, une innovation pour le B ` ati Tropical <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energyplus" title="energyplus">energyplus</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-layer%20of%20PCM" title=" multi-layer of PCM"> multi-layer of PCM</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20changing%20materials" title=" phase changing materials"> phase changing materials</a>, <a href="https://publications.waset.org/abstracts/search?q=tropical%20area" title=" tropical area"> tropical area</a> </p> <a href="https://publications.waset.org/abstracts/139700/numerical-modeling-of-phase-change-materials-walls-under-reunion-islands-tropical-weather" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139700.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
