Iridium is a material that has high activity and hydrogen selectivity for steam phase reforming. Nevertheless, a drawback for the use of iridium in aqueous-phase reforming is the low activity in water-gas shift reaction. Therefore, in this work, it is proposed the use of nickel and copper as a second metal in the catalyst to reach a synergetic effect. Iridium, iridium-nickel and iridium-copper catalysts were prepared by incipient wetness impregnation and evaluated in the aqueous-phase reforming of glycerol using CeO₂ or La₂O₃ as support. The catalysts were characterized by XRD, XPS, and EDX. The reactions were carried out in a fixed bed reactor feeding a solution of glycerol 10 wt% in water at 270°C, and reaction products were analyzed by gas chromatography. It was found that IrNi/CeO₂ reached highest glycerol conversion and hydrogen production, slightly above 70% and 43 vol% respectively. In terms of conversion, iridium is a promising metal, and its activity for hydrogen production can be enhanced when adding a second metal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aqueous-phase%20reforming" title="aqueous-phase reforming">aqueous-phase reforming</a>, <a href="https://publications.waset.org/abstracts/search?q=glycerol" title=" glycerol"> glycerol</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20production" title=" hydrogen production"> hydrogen production</a>, <a href="https://publications.waset.org/abstracts/search?q=iridium" title=" iridium"> iridium</a> </p> <a href="https://publications.waset.org/abstracts/70130/iridium-based-bimetallic-catalysts-for-hydrogen-production-through-glycerol-aqueous-phase-reforming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70130.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">326</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">7815</span> Structural Behavior of Subsoil Depending on Constitutive Model in Calculation Model of Pavement Structure-Subsoil System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kadela">M. Kadela</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The load caused by the traffic movement should be transferred in the road constructions in a harmless way to the pavement as follows: − on the stiff upper layers of the structure (e.g. layers of asphalt: abrading and binding), and − through the layers of principal and secondary substructure, − on the subsoil, directly or through an improved subsoil layer. Reliable description of the interaction proceeding in a system “road construction – subsoil” should be in such case one of the basic requirements of the assessment of the size of internal forces of structure and its durability. Analyses of road constructions are based on: − elements of mechanics, which allows to create computational models, and − results of the experiments included in the criteria of fatigue life analyses. Above approach is a fundamental feature of commonly used mechanistic methods. They allow to use in the conducted evaluations of the fatigue life of structures arbitrarily complex numerical computational models. Considering the work of the system “road construction – subsoil”, it is commonly accepted that, as a result of repetitive loads on the subsoil under pavement, the growth of relatively small deformation in the initial phase is recognized, then this increase disappears, and the deformation takes the character completely reversible. The reliability of calculation model is combined with appropriate use (for a given type of analysis) of constitutive relationships. Phenomena occurring in the initial stage of the system “road construction – subsoil” is unfortunately difficult to interpret in the modeling process. The classic interpretation of the behavior of the material in the elastic-plastic model (e-p) is that elastic phase of the work (e) is undergoing to phase (e-p) by increasing the load (or growth of deformation in the damaging structure). The paper presents the essence of the calibration process of cooperating subsystem in the calculation model of the system “road construction – subsoil”, created for the mechanistic analysis. Calibration process was directed to show the impact of applied constitutive models on its deformation and stress response. The proper comparative base for assessing the reliability of created. This work was supported by the on-going research project “Stabilization of weak soil by application of layer of foamed concrete used in contact with subsoil” (LIDER/022/537/L-4/NCBR/2013) financed by The National Centre for Research and Development within the LIDER Programme. M. Kadela is with the Department of Building Construction Elements and Building Structures on Mining Areas, Building Research Institute, Silesian Branch, Katowice, Poland (phone: +48 32 730 29 47; fax: +48 32 730 25 22; e-mail: m.kadela@ itb.pl). models should be, however, the actual, monitored system “road construction – subsoil”. The paper presents too behavior of subsoil under cyclic load transmitted by pavement layers. The response of subsoil to cyclic load is recorded in situ by the observation system (sensors) installed on the testing ground prepared for this purpose, being a part of the test road near Katowice, in Poland. A different behavior of the homogeneous subsoil under pavement is observed for different seasons of the year, when pavement construction works as a flexible structure in summer, and as a rigid plate in winter. Albeit the observed character of subsoil response is the same regardless of the applied load and area values, this response can be divided into: - zone of indirect action of the applied load; this zone extends to the depth of 1,0 m under the pavement, - zone of a small strain, extending to about 2,0 m. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=road%20structure" title="road structure">road structure</a>, <a href="https://publications.waset.org/abstracts/search?q=constitutive%20model" title=" constitutive model"> constitutive model</a>, <a href="https://publications.waset.org/abstracts/search?q=calculation%20model" title=" calculation model"> calculation model</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement" title=" pavement"> pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=FEA" title=" FEA"> FEA</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20of%20soil" title=" response of soil"> response of soil</a>, <a href="https://publications.waset.org/abstracts/search?q=monitored%20system" title=" monitored system"> monitored system</a> </p> <a href="https://publications.waset.org/abstracts/34789/structural-behavior-of-subsoil-depending-on-constitutive-model-in-calculation-model-of-pavement-structure-subsoil-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34789.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">357</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">7814</span> Research on the Internal Mechanism of Overseas Market Opportunity Construction of the Emerging-Market Multinational Enterprises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jie%20Zhang">Jie Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaomin%20Zhang"> Chaomin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on the network theory, this paper selects three Emerging-Market Multinationals Enterprises (EMNEs) as the research object and takes the typical overseas market opportunities constructed by them as the analysis unit to research the internal mechanism of overseas market opportunity construction of the EMNEs. The results show that: (1) EMNEs overseas market opportunity construction is a complex process, through the continuous interaction between enterprises and entities in the internal and external networks to achieve opportunity prototype, opportunity creation, and opportunity optimization in overseas markets. (2) Governments, foreign institutions and industry associations in the institutional network and competitors, partners, and customers in the commercial networks are the important entities in the construction of overseas market opportunities. Through the interaction of entity perception, relationship construction, and utilization, enterprises can obtain the necessary information, resources, and political asylum in the process of opportunity construction. (3) Organizations, project teams, and organizational sub-units within the enterprise are important internal entities for the construction of overseas market opportunities. Through the connection between different entities, they can achieve the circulation of resources within the organization and promote the opportunity construction of overseas markets. The research conclusions expand the relevant research on international opportunities and have inspiring and guiding significance for the expansion of EMNEs overseas markets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=international%20%28overseas%29%20opportunities" title="international (overseas) opportunities">international (overseas) opportunities</a>, <a href="https://publications.waset.org/abstracts/search?q=opportunity%20construction" title=" opportunity construction"> opportunity construction</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20entities" title=" network entities"> network entities</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction" title=" interaction"> interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20circulation" title=" resource circulation"> resource circulation</a> </p> <a href="https://publications.waset.org/abstracts/192551/research-on-the-internal-mechanism-of-overseas-market-opportunity-construction-of-the-emerging-market-multinational-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192551.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">17</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">7813</span> Development of the Accelerator Applied to an Early Stage High-Strength Shotcrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayanori%20Sugiyama">Ayanori Sugiyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Takahisa%20Hanei"> Takahisa Hanei</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasuhide%20Higo"> Yasuhide Higo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Domestic demand for the construction of tunnels has been increasing in recent years in Japan.

In the first phase of this research, a segment of road was designed using recycled materials such as Reclaimed Asphalt Pavement (RAP) on the top, the natural coarse base including 30% of RAP and recycled concrete blocks. The second part of this segment was designed using regular materials for each layer of the pavement. Both structures were built next to each other in order to analyze and measure the material properties as well as performance and environmental factors in the pavement under real traffic and weather conditions. Different monitoring devices were installed among the structure, based on the literature revision, such as soil cells, linear potentiometer, moisture sensors, and strain gauges that help us to know the C&DW as a part of the pavement structure. This research includes not only the physical characterization but also the measured parameters in a field such as an asphalt mixture (RAP) strain (ετ), vertical strain (εᵥ) and moisture control in coarse layers (%w), and the applied loads and strain in the subgrade (εᵥ). The results will show us what is happening with these materials in order to obtain not only a sustainable solution but also to know its behavior and lifecycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20pavements" title="sustainable pavements">sustainable pavements</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20%26%20demolition%20waste-C%26DW" title=" construction & demolition waste-C&DW"> construction & demolition waste-C&DW</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20rigid%20concrete" title=" recycled rigid concrete"> recycled rigid concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=reclaimed%20asphalt%20pavement-rap" title=" reclaimed asphalt pavement-rap"> reclaimed asphalt pavement-rap</a> </p> <a href="https://publications.waset.org/abstracts/131436/instrumentation-of-urban-pavements-built-with-construction-and-demolition-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131436.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7811</span> The Impact of Artificial Intelligence on Digital Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omil%20Nady%20Mahrous%20Maximous">Omil Nady Mahrous Maximous</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction industry is currently experiencing a shift towards digitisation. This transformation is driven by adopting technologies like Building Information Modelling (BIM), drones, and augmented reality (AR). These advancements are revolutionizing the process of designing, constructing, and operating projects. BIM, for instance, is a new way of communicating and exploiting technology such as software and machinery. It enables the creation of a replica or virtual model of buildings or infrastructure projects. It facilitates simulating construction procedures, identifying issues beforehand, and optimizing designs accordingly. Drones are another tool in this revolution, as they can be utilized for site surveys, inspections, and even deliveries. Moreover, AR technology provides real-time information to workers involved in the project. Implementing these technologies in the construction industry has brought about improvements in efficiency, safety measures, and sustainable practices. BIM helps minimize rework and waste materials, while drones contribute to safety by reducing workers' exposure to areas. Additionally, AR plays a role in worker safety by delivering instructions and guidance during operations. Although the digital transformation within the construction industry is still in its early stages, it holds the potential to reshape project delivery methods entirely. By embracing these technologies, construction companies can boost their profitability while simultaneously reducing their environmental impact and ensuring safer practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architectural%20education" title="architectural education">architectural education</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20industry" title=" construction industry"> construction industry</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20learning%20environments" title=" digital learning environments"> digital learning environments</a>, <a href="https://publications.waset.org/abstracts/search?q=immersive%20learning%20BIM" title=" immersive learning BIM"> immersive learning BIM</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20construction" title=" digital construction"> digital construction</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20technologies" title=" construction technologies"> construction technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation%20artificial%20intelligence" title=" digital transformation artificial intelligence"> digital transformation artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=collaboration" title=" collaboration"> collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20architecture" title=" digital architecture"> digital architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20design%20theory" title=" digital design theory"> digital design theory</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20selection" title=" material selection"> material selection</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20construction" title=" space construction"> space construction</a> </p> <a href="https://publications.waset.org/abstracts/185395/the-impact-of-artificial-intelligence-on-digital-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185395.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">58</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">7810</span> Students’ Level of Knowledge Construction and Pattern of Social Interaction in an Online Forum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Durairaj">K.

Online forum allows participants to interact, construct knowledge, and can be used to complement face to face sessions in blended learning courses. However, to what extent do the students perceive the benefits or advantages of forum remain to be seen. Through content and social network analyses, instructors will be able to gauge the students’ engagement and knowledge construction level. Thus, this study aims to analyze the students’ level of knowledge construction and their participation level that occur through online discussion. It also attempts to investigate the relationship between the level of knowledge construction and their social interaction patterns. The sample involves 23 students undertaking a master course in one public university in Malaysia. The asynchronous discussion forum was conducted for three weeks as part of the course requirement. The finding indicates that the level of knowledge construction is quite low. Also, the density value of 0.11 indicating that the overall communication among the participants in the forum is low. This study reveals that strong and significant correlations between SNA measures (in-degree centrality, out-degree centrality) and level of knowledge construction.

Although the private sector has taken the initiative in implementing IPD and taken advantage of new technology such as building information modeling (BIM) in delivering projects, IPD remains less known and rarely used in public sector construction. The focus of this paper is set on the use of IPD in projects in public sector, which is potentially complemented by the use of analytical functionalities for workface planning and construction oriented design enabled by recent research advances in BIM. Experiences and lessons learned from implementing IPD in the private sector and in BIM-based construction automation research would play a vital role in reducing barriers and eliminating issues in connection with project delivery in the public sector. The paper elaborates issues challenges, contractual relationships and the interactions throughout the planning, design and construction phases in the context of implementing IPD on construction projects in the public sector. A slab construction case is used as a ‘sandbox’ model to elaborate (1) the ideal way of communication, integration, and collaboration among all the parties involved in project delivery in planning and (2) the execution of projects by using IDP principles and optimization, simulation analyses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integrated%20project%20delivery" title="integrated project delivery">integrated project delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=IPD" title=" IPD"> IPD</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20information%20modeling" title=" building information modeling"> building information modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM" title=" BIM"> BIM</a> </p> <a href="https://publications.waset.org/abstracts/108107/challenges-and-opportunities-for-implementing-integrated-project-delivery-method-in-public-sector-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108107.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">202</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">7807</span> Cost Comparison between R.C.C.

The rapid growth in Steel-Concrete Composite construction has widely decreased the conventional R.C.C structures. Steel Concrete composite construction has obtained extensive receiving around the globe. It is considering the fact that R.C.C structures construction is most suitable and economical for low-rise construction, so it is used in farming systems in most of the buildings. However, increased dead load, span restriction, less stiffness and risky formwork make R.C.C construction uneconomical and not suitable when it comes to intermediate to high-rise buildings. A Base + Ground +11 storey commercial building was designed on ETABS 2017 and made a comparison between conventional R.C.C and encased composite column structure. After performing Equivalent Static non-linear analysis, it has been found that construction cost is 13.01% more than R.C.C structure but encased composite column building has 7.7% more floor area. This study will help in understanding the behavior of conventional R.C.C structure and Encased Composite column structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20columns%20structure" title="composite columns structure">composite columns structure</a>, <a href="https://publications.waset.org/abstracts/search?q=equivalent%20static%20non-linear%20analysis" title=" equivalent static non-linear analysis"> equivalent static non-linear analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=comparison%20between%20R.C.C%20and%20encased%20composite%20column%20structures" title=" comparison between R.C.C and encased composite column structures"> comparison between R.C.C and encased composite column structures</a>, <a href="https://publications.waset.org/abstracts/search?q=cost-effective%20structure" title=" cost-effective structure"> cost-effective structure</a> </p> <a href="https://publications.waset.org/abstracts/140964/cost-comparison-between-rcc-structures-and-composite-columns-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140964.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">199</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">7806</span> Fused Structure and Texture (FST) Features for Improved Pedestrian Detection </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussin%20K.%20Ragb">Hussin K.

Asari </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a pedestrian detection descriptor called Fused Structure and Texture (FST) features based on the combination of the local phase information with the texture features. Since the phase of the signal conveys more structural information than the magnitude, the phase congruency concept is used to capture the structural features. On the other hand, the Center-Symmetric Local Binary Pattern (CSLBP) approach is used to capture the texture information of the image. The dimension less quantity of the phase congruency and the robustness of the CSLBP operator on the flat images, as well as the blur and illumination changes, lead the proposed descriptor to be more robust and less sensitive to the light variations. The proposed descriptor can be formed by extracting the phase congruency and the CSLBP values of each pixel of the image with respect to its neighborhood. The histogram of the oriented phase and the histogram of the CSLBP values for the local regions in the image are computed and concatenated to construct the FST descriptor. Several experiments were conducted on INRIA and the low resolution DaimlerChrysler datasets to evaluate the detection performance of the pedestrian detection system that is based on the FST descriptor. A linear Support Vector Machine (SVM) is used to train the pedestrian classifier. These experiments showed that the proposed FST descriptor has better detection performance over a set of state of the art feature extraction methodologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pedestrian%20detection" title="pedestrian detection">pedestrian detection</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20congruency" title=" phase congruency"> phase congruency</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20phase" title=" local phase"> local phase</a>, <a href="https://publications.waset.org/abstracts/search?q=LBP%20features" title=" LBP features"> LBP features</a>, <a href="https://publications.waset.org/abstracts/search?q=CSLBP%20features" title=" CSLBP features"> CSLBP features</a>, <a href="https://publications.waset.org/abstracts/search?q=FST%20descriptor" title=" FST descriptor"> FST descriptor</a> </p> <a href="https://publications.waset.org/abstracts/36643/fused-structure-and-texture-fst-features-for-improved-pedestrian-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36643.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">488</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">7805</span> Adoption of Noise and Vibration Management Tools for Major Infrastructure Projects in Sydney, Australia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Morris">Adrian Morris</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodney%20Phillips"> Rodney Phillips</a>, <a href="https://publications.waset.org/abstracts/search?q=Mattia%20Tabacchi"> Mattia Tabacchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Minimizing construction noise and vibration impacts is a key challenge for major infrastructure projects in urban environments. Before commencing construction works, Construction Noise and Vibration Management Plan (CNVMP) and Construction Noise and Vibration Impact Statements (CNVIS) are required to be prepared and submitted to the relevant government authorities for review and approval. However, the assessment of potential impacts from work activities at pre-approval stage may be inaccurate as works methodology and scheduling are yet to be determined. In response, noise and vibration management tools have been developed to refine and supplement the CNVIS as works progress. These tools have been successfully implemented in major infrastructure projects allowing contractors to plan and assess construction works in a cost effective and timely manner. As a result, noise and vibration management tools have been incorporated into management plans and are increasingly required by regulators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=noise%20management" title="noise management">noise management</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20noise" title=" environmental noise"> environmental noise</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure%20projects" title=" infrastructure projects"> infrastructure projects</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration" title=" vibration"> vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20effective" title=" cost effective"> cost effective</a> </p> <a href="https://publications.waset.org/abstracts/154101/adoption-of-noise-and-vibration-management-tools-for-major-infrastructure-projects-in-sydney-australia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154101.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">7804</span> Extraction of Dyes Using an Aqueous Two-Phase System in Stratified and Slug Flow Regimes of a Microchannel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garima">Garima</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Pushpavanam"> S. Pushpavanam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, analysis of an Aqueous two-phase (polymer-salt) system for extraction of sunset yellow dye is carried out. A polymer-salt ATPS i.e.; Polyethylene glycol-600 and anhydrous sodium sulfate is used for the extraction. Conditions are chosen to ensure that the extraction results in a concentration of the dye in one of the phases. The dye has a propensity to come to the Polyethylene glycol-600 phase. This extracted sunset yellow dye is degraded photo catalytically into less harmful components. The cloud point method was used to obtain the binodal curve of ATPS. From the binodal curve, the composition of salt and Polyethylene glycol -600 was chosen such that the volume of Polyethylene glycol-600 rich phase is low. This was selected to concentrate the dye from a dilute solution in a large volume of contaminated solution into a small volume. This pre-concentration step provides a high reaction rate for photo catalytic degradation reaction. Experimentally the dye is extracted from the salt phase to Polyethylene glycol -600 phase in batch extraction. This was found to be very fast and all dye was extracted. The concentration of sunset yellow dye in salt and polymer phase is measured at 482nm by ultraviolet-visible spectrophotometry. The extraction experiment in micro channels under stratified flow is analyzed to determine factors which affect the dye extraction. Focus will be on obtaining slug flow by adding nanoparticles in micro channel. The primary aim is to exploit the fact that slug flow will help improve mass transfer rate from one phase to another through internal circulation in dispersed phase induced by shear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aqueous%20two%20phase%20system" title="aqueous two phase system">aqueous two phase system</a>, <a href="https://publications.waset.org/abstracts/search?q=binodal%20curve" title=" binodal curve"> binodal curve</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=sunset%20yellow%20dye" title=" sunset yellow dye"> sunset yellow dye</a> </p> <a href="https://publications.waset.org/abstracts/72490/extraction-of-dyes-using-an-aqueous-two-phase-system-in-stratified-and-slug-flow-regimes-of-a-microchannel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72490.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">358</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">7803</span> Contributing Factors Affecting the Safety in Construction Sites of Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzana%20Rahman">Farzana Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hossain%20Ezaz"> Mohammed Hossain Ezaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Dipak%20Halder"> Dipak Halder</a>, <a href="https://publications.waset.org/abstracts/search?q=Proshanta%20Mondal"> Proshanta Mondal </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Site safety is an important function regardless of project size. A key goal, which must be met for a successful project, is to finish the project with a good safety record. Construction safety is an important issue in all over the world. Today, developed countries strictly follow the safety procedure to avoid any hazard, accident or fatality. However, for a least developed country like Bangladesh, still accidents and fatalities are quite high due to lack of safety management. With the increased volume of construction work in Bangladesh, the need for proper attention in safety issues has become essential for human, economic and other consideration. Recently lots of accidents are taking place in construction sites of Bangladesh causing severe injury to death to the workers and pedestrians. There are a number of reasons/factors that these high numbers are widespread to the construction industry that are not found in most other businesses. The objective of this research work is to identify and explore the various factor that affect the construction site safety in Bangladesh. A questionnaire surveys was conducted to the reputed construction companies of Bangladesh to examine the present safety situation in construction sites. Nine factors were selected for the survey. The finding shows that 78% of organizations’ from the respondents are conscious about the safety procedure and they usually provide safety measures for the workers. Promotion of safety measures at the working site results in a better working environment, higher productivity and greater contentment among the workers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20sites" title="construction sites">construction sites</a>, <a href="https://publications.waset.org/abstracts/search?q=fatalities" title=" fatalities"> fatalities</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20issues" title=" safety issues"> safety issues</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20situation" title=" safety situation"> safety situation</a> </p> <a href="https://publications.waset.org/abstracts/21199/contributing-factors-affecting-the-safety-in-construction-sites-of-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21199.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">569</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">7802</span> Study of Heat Transfer in the Absorber Plates of a Flat-Plate Solar Collector Using Dual-Phase-Lag Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Ching%20Yang">Yu-Ching Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Haw-Long%20Lee"> Haw-Long Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Win-Jin%20Chang"> Win-Jin Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work numerically analyzes the transient heat transfer in the absorber plates of a flat-plate solar collector based on the dual-phase-lag (DPL) heat conduction model.

Phase shift cavity ring down spectroscopy is not only easy to use but is also capable of overcoming the said problems. This technique compares the phase difference between the signal coming out of the cavity with the reference signal. Detection of any material is made by the phase difference between them. By using this technique, air, water, and isopropyl alcohol can be recognized easily.

This ensures they can react quickly when needed. A study was conducted to develop a way to locate and track materials on construction sites. The system is an RFID/GPS integration that's required to pull off this feat. The study also reports how the platform has been used in construction. They found many advantages to using it, including reductions in both time and costs as well as improved management of materials orders. . For example, the time in which a project could start up was shortened from two weeks to three days with just a single digital order. As of now, the technology is still limited in its widespread adoption due largely to overall lack of awareness and difficulty connecting to it. However, as more and more companies embrace it in construction, the technology is expected to become ubiquitous. The developed platform provides contractors and construction managers with real-time information about the status of materials and work, allowing them to better manage the workflow in a project. The study sheds new light on this subject, which is essential to know. This work is becoming increasingly aware of the use of smart tools in constructing buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=materials%20management" title="materials management">materials management</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things%20%28IoT%29" title=" internet of things (IoT)"> internet of things (IoT)</a>, <a href="https://publications.waset.org/abstracts/search?q=radio%20frequency%20identification%20%28RFID%29" title=" radio frequency identification (RFID)"> radio frequency identification (RFID)</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20site" title=" construction site"> construction site</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a> </p> <a href="https://publications.waset.org/abstracts/150430/radio-frequency-identification-rfid-cost-effective-location-based-system-for-managing-construction-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150430.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">81</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">7798</span> A Review on the Use of Plastic Waste with Viable Materials in Composite Construction Block</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohan%20T.%20Harish">Mohan T.

The Industrialised Building System (IBS) has been recognised as a viable method for improving overall construction performance in terms of quality, cost, safety and health, waste reduction, and productivity. The Malaysian construction industry is considered one of the contributors to the development of the country. The acceptance level of IBS is still below government expectations. Thus, the Malaysian government has been continuously encouraging the industry to use and implement IBS. Conventional systems have several drawbacks, including project delays, low economic efficiency, excess inventory, and poor product quality. When it comes to implementing IBS, construction companies still face several obstacles and problems, notably in terms of contractual and procurement concerns, which leads to the low adoption of IBS in Malaysia. There are barriers to the acceptance of IBS technology, focused on awareness of historical failure and risks connected to IBS practices to provide enhanced performance. Therefore, the transformation from the existing conventional building systems to the industrialized building systems (IBS) is needed more than ever. The flexibility of IBS in Malaysia’s construction industry is very low due to numerous shortcomings and obstacles. Due to its environmental, economic, and social benefits, IBS could play a significant role in the Malaysian construction industry in the future. This paper concentrates on the potential role of IBS in sustainable construction practices in Malaysia. It also highlights the awareness, barriers, advantages, and disadvantages of IBS in the construction sector. The study concludes with recommendations for Malaysian construction stakeholders to encourage and increase the utilization of industrialised building systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20industry" title="construction industry">construction industry</a>, <a href="https://publications.waset.org/abstracts/search?q=industrialized%20building%20system" title=" industrialized building system"> industrialized building system</a>, <a href="https://publications.waset.org/abstracts/search?q=barriers" title=" barriers"> barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=advantages%20and%20disadvantages" title=" advantages and disadvantages"> advantages and disadvantages</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysia" title=" Malaysia"> Malaysia</a> </p> <a href="https://publications.waset.org/abstracts/167550/the-potential-role-of-industrialized-building-systems-in-malaysian-sustainable-construction-awareness-and-barriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167550.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">103</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">7796</span> Analysis of Structural Phase Stability of Strontium Sulphide under High Pressure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shilpa%20Kapoor">Shilpa Kapoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Namrata%20Yaduvanshi"> Namrata Yaduvanshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pooja%20Pawar"> Pooja Pawar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadhna%20Singh"> Sadhna Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Three Body Interaction Potential (TBIP) model is developed to study the high pressure phase transition of SrS having NaCl (B1) structure at room temperature.

Various risk factors of exerting BIM during different phases of the project lifecycle are identified with the help of Delphi method, experts’ opinions and related literature. Afterward, Shannon’s entropy and Fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Situation) are applied to derive priorities of the identified risk factors. Results indicated that lack of knowledge between professional engineers about workflows in BIM and conflict of opinions between different stakeholders are the risk factors with the highest priority. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk" title="risk">risk</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM" title=" BIM"> BIM</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20TOPSIS" title=" fuzzy TOPSIS"> fuzzy TOPSIS</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20projects" title=" construction projects"> construction projects</a> </p> <a href="https://publications.waset.org/abstracts/115013/risk-assessment-of-building-information-modelling-adoption-in-construction-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115013.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">229</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">7794</span> Effect of Martensite Content and Its Morphology on Mechanical Properties of Microalloyed Dual Phase Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20K.%20Manoj">M.

The human resources working in the construction industry have various problems and deficiencies, and in order to solve these problems, there is a need for basic management and training of these people in order to lower the construction costs and increase the quality of the projects, especially in mass house building projects. The success of any project in reaching short and long-term professional goals depends on the efficient combination of work tools, financial resources, raw materials, and most importantly, human resources. Today, due to the complexity and diversity of each project, specialized management fields have emerged to maximize the potential benefits of each component of that project. Human power is known as the most important resource in construction projects for its successful implementation, but unfortunately, due to the low cost of human power compared to other resources, such as materials and machinery, little attention is paid to it. With the correct management and training of human resources, which depends on its correct planning and development, it is possible to improve the performance of construction projects. In this article, the training and motivation of construction industry workers and their effects on the effectiveness of projects in this industry have been researched. In this regard, some barriers to the training and motivation of construction workers and personnel have been identified and solutions have been provided for construction companies. Also, the impact of workers and unskilled people on the efficiency of construction projects is investigated. The results of the above research show that by increasing the use of correct and basic training for human resources, we will see positive results and effects on the performance of construction projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20resources" title="human resources">human resources</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20industry" title=" construction industry"> construction industry</a>, <a href="https://publications.waset.org/abstracts/search?q=principled%20training" title=" principled training"> principled training</a>, <a href="https://publications.waset.org/abstracts/search?q=skilled%20and%20unskilled%20workers" title=" skilled and unskilled workers"> skilled and unskilled workers</a> </p> <a href="https://publications.waset.org/abstracts/162020/the-effect-of-principled-human-resource-management-and-training-based-on-existing-standards-in-order-to-improve-the-quality-of-construction-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162020.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">96</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">7792</span> Dynamic Study of a Two Phase Thermosyphon Loop</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Selva%20Georgena%20D.">Selva Georgena D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Videcoq%20Etienne"> Videcoq Etienne</a>, <a href="https://publications.waset.org/abstracts/search?q=Caner%20Julien"> Caner Julien</a>, <a href="https://publications.waset.org/abstracts/search?q=Benselama%20Adel"> Benselama Adel</a>, <a href="https://publications.waset.org/abstracts/search?q=Girault%20Manu"> Girault Manu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Two-Phase Thermosyphon Loop (TPTL) is a passive cooling system which does not require a pump to function.

Moreover, the dynamic behavior of TPTL shows some physical instabilities and the actual occurrence of such a behavior remains unknown.

Indigo is a blue coloured dye used all over the world in large quantity. The indigo dye produced and used in textile industries is synthetic having toxic effect, thus there is an increase in interest for natural dyes owing to the environmental concerns. The present study focuses on the use of a strain Pandoraea sp. isolated from garage soil, for the production of indigo in fed batch bioreactor. A comparative study between single phase and two phase production was carried out in this work. The blue colour produced during the experiments was analyzed using, TLC, UV-visible spectrophotometer and FTIR technique. The blue pigment was found to be indigo. The production of bio-indigo was done in a single phase fermentor carrying medium and substrate indole in dissolved form and was found to produce maximum of 0.041 g/L of indigo. Whereas there was an increase in production of indigo to 0.068 g/L in a two phase, water-silicone oil system. In this study the advantage of using second phase as silicone oil has enhanced the indigo production, as the second phase made the substrate available to the bacteria by increasing the surface area as well as it helped to prevent the inhibition effect of the high concentration of substrate, indole. The effect of single and two phases on the growth of bacteria was also studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dyes" title="dyes">dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=fed%20batch%20reactor" title=" fed batch reactor"> fed batch reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=indole" title=" indole"> indole</a>, <a href="https://publications.waset.org/abstracts/search?q=Indigo" title=" Indigo "> Indigo </a> </p> <a href="https://publications.waset.org/abstracts/37269/indigo-production-in-a-fed-batch-bioreactor-using-aqueous-solvent-two-phase-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37269.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">433</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">7789</span> The Influence of Microcapsulated Phase Change Materials on Thermal Performance of Geopolymer Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vinh%20Duy%20Cao">Vinh Duy Cao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shima%20Pilehvar"> Shima Pilehvar</a>, <a href="https://publications.waset.org/abstracts/search?q=Anna%20M.%20Szczotok"> Anna M.

One of the solutions to reduce the energy consumption for the building is to improve construction techniques and enhance material technology. Recently, microcapsulated phase change materials (MPCM) with high energy storage capacity within the phase transition temperature of the materials is a potential method to conserve and save energy. A new composite materials with high energy storage capacity by mixing MPCM into concrete for passive building technology is the promising candidate to reduce the energy consumption. One of the most untilized building materials for mixing with MPCM is Portland cement concrete. However, the emission of carbon dioxide (CO2) due to producing cement which plays the important role in the global warming is the main drawback of PCC. Accordingly, an environmentally friendly building material, geopolymer, which is synthesized by the reaction between the industrial waste material (aluminosilicate) and a strong alkali activator, is a potential materials to mixing with MPCM. Especially, the effect of MPCM on the thermal and mechanical properties of geopolymer concrete (GPC) is very limited. In this study, high thermal energy storage capacity materials were fabricated by mixing MPCM into geopolymer concrete. This article would investigate the effect of MPCM concentration on thermal and mechanical properties of GPC. The target is to balance the effect of MPCM on improving the thermal performance and maintaining the compressive strength of the geopolymer concrete at an acceptable level for building application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microencapsulated%20phase%20change%20materials" title="microencapsulated phase change materials">microencapsulated phase change materials</a>, <a href="https://publications.waset.org/abstracts/search?q=geopolymer%20concrete" title=" geopolymer concrete"> geopolymer concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage%20capacity" title=" energy storage capacity"> energy storage capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20performance" title=" thermal performance"> thermal performance</a> </p> <a href="https://publications.waset.org/abstracts/68879/the-influence-of-microcapsulated-phase-change-materials-on-thermal-performance-of-geopolymer-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68879.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">309</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">7788</span> Anonymous Gel-Fluid Transition of Solid Supported Lipids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20Poursoroush">Asma Poursoroush</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid-supported lipid bilayers are often used as a simple model for studies of biological membranes. The presence of a solid substrate that interacts attractively with lipid head-groups is expected to affect the phase behavior of the supported bilayer. Molecular dynamics simulations of a coarse-grained model are thus performed to investigate the phase behavior of supported one-component lipid bilayer membranes. Our results show that the attraction of the lipid head groups to the substrate leads to a phase behavior that is different from that of a free standing lipid bilayer. In particular, we found that the phase behaviors of the two leaflets are decoupled in the presence of a substrate. The proximal leaflet undergoes a clear gel-to-fluid phase transition at a temperature lower than that of a free standing bilayer, and that decreases with increasing strength of the substrate-lipid attraction. The distal leaflet, however, undergoes a change from a homogeneous liquid phase at high temperatures to a heterogeneous state consisting of small liquid and gel domains, with the average size of the gel domains that increases with decreasing temperature. While the chain order parameter of the proximal leaflet clearly shows a gel-fluid phase transition, the chain order parameter of the distal leaflet does not exhibit a clear phase transition. The decoupling in the phase behavior of the two leaflets is due to a non-symmteric lipid distribution in the two leaflets resulting from the presence of the substrate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=membrane" title="membrane">membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=substrate" title=" substrate"> substrate</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics" title=" molecular dynamics"> molecular dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/78473/anonymous-gel-fluid-transition-of-solid-supported-lipids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78473.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">195</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">7787</span> Soil Reinforcement by Stone Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saou%20Mohamed%20Amine">Saou Mohamed Amine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction industry has been identified as a user of substantial amount of materials and energy resources that has an enormous impact on environment.
