waste from food packaging is collected and recycled for further use in the food industry. Therefore, reusing these waste plastics for building applications can be an attractive alternative to disposal in order to reduce the problem of waste management and to make up for the depletion of raw materials needed for construction. In this study, experiments were conducted on the mechanical properties (compressive and flexural strength, elastic modulus), physical properties (density, workability, porosity, and water permeability) and durability (freeze/thaw resistance) of cementitious mortars with additions of recycled low-/high-density polyethylene (LDPE/HDPE)/ polypropylene (PP) regrind (addition of 5% and 10% by weight) and LDPE sheets (addition of 0.5% and 1.5% by weight) coming from food packaging. The results show that as the addition of plastic material increases, the density and mechanical properties of the mortars decrease compared to conventional ones. Porosity is similar in all the mixtures made, while the workability and the permeability are affected not only by the amount added but also by the shape of the plastic aggregate. Freeze/thaw resistance, on the other hand, is significantly higher in mortars with plastic aggregates than in traditional mortar. This feature may be interesting for the realization of outdoor mortars in cold environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20packaging%20waste" title="food packaging waste">food packaging waste</a>, <a href="https://publications.waset.org/abstracts/search?q=durability%20properties" title=" durability properties"> durability properties</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=mortar" title=" mortar"> mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20PE" title=" recycled PE"> recycled PE</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20PP" title=" recycled PP"> recycled PP</a> </p> <a href="https://publications.waset.org/abstracts/144698/mechanical-physical-and-durability-properties-of-cement-mortars-added-with-recycled-pppe-based-food-packaging-waste-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144698.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4754</span> Pre-Operative Tool for Facial-Post-Surgical Estimation and Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayat%20E.%20Ali">Ayat E.

Methods: To this aim, we implemented a software which used data from the internet for facial skin diseases, skin burns, pre-and post-images for plastic surgeries then the post- surgical prediction is done by using K-nearest neighbor (KNN). So we designed and fabricated a smart mirror divided into two parts a screen and a reflective mirror so patient's pre- and post-appearance will be showed at the same time. Results: We worked on some skin diseases like vitiligo, skin burns and wrinkles. We classified the three degrees of burns using KNN classifier with accuracy 60%. We also succeeded in segmenting the area of vitiligo. Our future work will include working on more skin diseases, classify them and give a prediction for the look after the surgery. Also we will go deeper into facial deformities and plastic surgeries like nose reshaping and face slim down. Conclusion: Our project will give a prediction relates strongly to the real look after surgery and decrease different diagnoses among doctors. Significance: The mirror may have broad societal appeal as it will make the distance between patient's satisfaction and the medical standards smaller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=k-nearest%20neighbor%20%28knn%29" title="k-nearest neighbor (knn)">k-nearest neighbor (knn)</a>, <a href="https://publications.waset.org/abstracts/search?q=face%20detection" title=" face detection"> face detection</a>, <a href="https://publications.waset.org/abstracts/search?q=vitiligo" title=" vitiligo"> vitiligo</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20deformity" title=" bone deformity"> bone deformity</a> </p> <a href="https://publications.waset.org/abstracts/108026/pre-operative-tool-for-facial-post-surgical-estimation-and-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108026.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">164</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">4753</span> Design and Analysis of Deep Excavations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barham%20J.%20Nareeman">Barham J.

In some cases, these walls may be braced by internal braces or tie back anchors. Tie back anchors are by far the predominant method for wall support, the large working space inside the excavation provided by a tieback anchor system has a significant construction advantage. This paper aims to analyze a deep excavation bracing system of contiguous pile wall braced by pre-stressed tie back anchors, which is a part of a huge residential building project, located in Turkey/Gaziantep province. The contiguous pile wall will be constructed with a length of 270 m that consists of 285 piles, each having a diameter of 80 cm, and a center to center spacing of 95 cm. The deformation analysis was carried out by a finite element analysis tool using PLAXIS. In the analysis, beam element method together with an elastic perfect plastic soil model and Soil Hardening Model was used to design the contiguous pile wall, the tieback anchor system, and the soil. The two soil clusters which are limestone and a filled soil were modelled with both Hardening soil and Mohr Coulomb models. According to the basic design, both soil clusters are modelled as drained condition. The simulation results show that the maximum horizontal movement of the walls and the maximum settlement of the ground are convenient with 300 individual case histories which are ranging between 1.2mm and 2.3mm for walls, and 15mm and 6.5mm for the settlements. It was concluded that tied-back contiguous pile wall can be satisfactorily modelled using Hardening soil model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20excavation" title="deep excavation">deep excavation</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-stressed%20tie%20back%20anchors" title=" pre-stressed tie back anchors"> pre-stressed tie back anchors</a>, <a href="https://publications.waset.org/abstracts/search?q=contiguous%20pile%20wall" title=" contiguous pile wall"> contiguous pile wall</a>, <a href="https://publications.waset.org/abstracts/search?q=PLAXIS" title=" PLAXIS"> PLAXIS</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20deflection" title=" horizontal deflection"> horizontal deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20settlement" title=" ground settlement"> ground settlement</a> </p> <a href="https://publications.waset.org/abstracts/53000/design-and-analysis-of-deep-excavations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53000.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">255</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">4752</span> Investigation of Seismic T-Resisting Frame with Shear and Flexural Yield of Horizontal Plate Girders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helia%20Barzegar%20Sedigh">Helia Barzegar Sedigh</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Hamedi"> Farzaneh Hamedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Payam%20Ashtari"> Payam Ashtari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are some limitations in common structural systems, such as providing appropriate lateral stiffness, adequate ductility, and architectural openings at the same time. Consequently, the concept of T-Resisting Frame (TRF) has been introduced to overcome all these deficiencies. The configuration of TRF in this study is a Vertical Plate Girder (VPG) which is placed within the span and two Horizontal Plate Girders (HPGs) connect VPG to side columns at each story level by the use of rigid connections. System performance is improved by utilizing rigid connections in side columns base joint. Shear yield of HPGs causes energy dissipation in TRF; therefore, high plastic deformation in web of HPGs and VPG affects the ductility of system. Moreover, in order to prevent shear buckling in web of TRF’s members and appropriate criteria for placement of web stiffeners are applied. In this paper, an experimental study is conducted by applying cyclic loading and using finite element models and numerical studies such as push over method are assessed on shear and flexural yielding of HPGs. As a result, seismic parameters indicate adequate lateral stiffness, and high ductility factor of 6.73, and HPGs’ shear yielding achieved as a proof of TRF’s better performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental%20study" title="experimental study">experimental study</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20and%20shear%20yielding" title=" flexural and shear yielding"> flexural and shear yielding</a>, <a href="https://publications.waset.org/abstracts/search?q=t-resisting%20frame" title=" t-resisting frame"> t-resisting frame</a> </p> <a href="https://publications.waset.org/abstracts/72495/investigation-of-seismic-t-resisting-frame-with-shear-and-flexural-yield-of-horizontal-plate-girders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72495.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">232</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">4751</span> Environmental Impact of Pallets in the Supply Chain: Including Logistics and Material Durability in a Life Cycle Assessment Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joana%20Almeida">Joana Almeida</a>, <a href="https://publications.waset.org/abstracts/search?q=Kendall%20Reid"> Kendall Reid</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Bengtsson"> Jonas Bengtsson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pallets are devices that are used for moving and storing freight and are nearly omnipresent in supply chains. The market is dominated by timber pallets, with plastic being a common alternative. Either option underpins the use of important resources (oil, land, timber), the emission of greenhouse gases and additional waste generation in most supply chains. This study uses a dynamic approach to the life cycle assessment (LCA) of pallets. It demonstrates that what ultimately defines the environmental burden of pallets in the supply chain is how often the length of its lifespan, which depends on the durability of the material and on how pallets are utilized. This study proposes a life cycle assessment (LCA) of pallets in supply chains supported by an algorithm that estimates pallet durability in function of material resilience and of logistics. The LCA runs from cradle-to-grave, including raw material provision, manufacture, transport and end of life. The scope is representative of timber and plastic pallets in the Australian and South-East Asia markets. The materials included in this analysis are: -tropical mixed hardwood, unsustainably harvested in SE Asia; -certified softwood, sustainably harvested; -conventional plastic, a mix of virgin and scrap plastic; -recycled plastic pallets, 100% mixed plastic scrap, which are being pioneered by Re > Pal. The logistical model purports that more complex supply chains and rougher handling subject pallets to higher stress loads. More stress shortens the lifespan of pallets in function of their composition. Timber pallets can be repaired, extending their lifespan, while plastic pallets cannot. At the factory gate, softwood pallets have the lowest carbon footprint. Re > pal follows closely due to its burden-free feedstock. Tropical mixed hardwood and plastic pallets have the highest footprints. Harvesting tropical mixed hardwood in SE Asia often leads to deforestation, leading to emissions from land use change. The higher footprint of plastic pallets is due to the production of virgin plastic. Our findings show that manufacture alone does not determine the sustainability of pallets. Even though certified softwood pallets have lower carbon footprint and their lifespan can be extended by repair, the need for re-supply of materials and disposal of waste timber offsets this advantage. It also leads to most waste being generated among all pallets. In a supply chain context, Re > Pal pallets have the lowest footprint due to lower replacement and disposal needs. In addition, Re > Pal are nearly ‘waste neutral’, because the waste that is generated throughout their life cycle is almost totally offset by the scrap uptake for production. The absolute results of this study can be confirmed by progressing the logistics model, improving data quality, expanding the range of materials and utilization practices. Still, this LCA demonstrates that considering logistics, raw materials and material durability is central for sustainable decision-making on pallet purchasing, management and disposal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20footprint" title="carbon footprint">carbon footprint</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20plastic" title=" recycled plastic"> recycled plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=waste" title=" waste"> waste</a> </p> <a href="https://publications.waset.org/abstracts/71380/environmental-impact-of-pallets-in-the-supply-chain-including-logistics-and-material-durability-in-a-life-cycle-assessment-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71380.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">221</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">4750</span> Response of Different Mulch Materials on Cowpea (Vigna unguiculata ) Growth and Yield in Tolon District</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adu%20Micheal%20Kwaku">Adu Micheal Kwaku</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamptey%20Shirley"> Lamptey Shirley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cowpea (Vigna unguiculata (L.) Walpis) is a major food grain legume in Ghana and plays a significant role in consumer diets. Drought in rain-fed crop production is known to cause substantial crop yield reduction due to their negative impacts on plant growth, physiology, and reproduction. There are various ways of reducing the effect of drought or addressing the problem of drought stress, including irrigation, breeding, and mulching. Among these three ways of reducing the effect of drought stress, the cheapest and quickest method is mulching. The broad objective of this project is to determine the influence of mulching on the performance of cowpea. The experiment was conducted at Planting for future garden located at Nyankpala Campus of the University for Development Studies (UDS), comprising five treatments (black plastic, rice hull, groundnut hull, dry grass mulch, and control). The treatments were evaluated in a Randomized Complete Block Design (RCBD) with three replications. The result shows that black plastic mulch increased soil moisture by 1, 8, 15, and 24% compared to rice hull, groundnut hull, dry grass, and control, respectively. Increased soil moisture translated into black plastic mulch increasing grain yield by 8, 25, 39, and 46% compared to groundnut hull, rice hull, dry grass and control, respectively. However, black plastic mulch increased the cost of production, resulting in decreased net returns compared to the other treatment.

Especially, attempts to save costs for building BIM-related infrastructure and provide various BIM services compatible with domestic processes include studies to link between BIM and cloud computing technologies. Also in this study, the author attempted to develop a cloud BIM service operation model through analyzing the level of BIM applications for the construction sector and deriving relevant service areas, and find how to link BIM services to the cloud operation model, as through archiving BIM data and creating a revenue structure so that the BIM services may grow spontaneously, considering a demand for cloud resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20IT" title="construction IT">construction IT</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM%20%28building%20information%20modeling%29" title=" BIM (building information modeling)"> BIM (building information modeling)</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM%20service%20based%20cloud%20computing" title=" BIM service based cloud computing"> BIM service based cloud computing</a> </p> <a href="https://publications.waset.org/abstracts/30185/a-study-on-how-to-link-bim-services-to-cloud-computing-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30185.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">487</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">4748</span> Design of a Vehicle Door Structure Based on Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tawanda%20Mushiri">Tawanda Mushiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Mbohwa"> Charles Mbohwa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The performance of door assembly is very significant for the vehicle design. In the present paper, the finite element method is used in the development processes of the door assembly. The stiffness, strength, modal characteristic, and anti-extrusion of a newly developed passenger vehicle door assembly are calculated and evaluated by several finite element analysis commercial software. The structural problems discovered by FE analysis have been modified and finally achieved the expected door structure performance target of this new vehicle. The issue in focus is to predict the performance of the door assembly by powerful finite element analysis software, and optimize the structure to meet the design targets. It is observed that this method can be used to forecast the performance of vehicle door efficiently when it’s designed. In order to reduce lead time and cost in the product development of vehicles more development will be made virtually. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicle%20door" title="vehicle door">vehicle door</a>, <a href="https://publications.waset.org/abstracts/search?q=structure" title=" structure"> structure</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness" title=" stiffness"> stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20characteristic" title=" modal characteristic"> modal characteristic</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-extrusion" title=" anti-extrusion"> anti-extrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Finite%20Element%20Method" title=" Finite Element Method"> Finite Element Method</a> </p> <a href="https://publications.waset.org/abstracts/13002/design-of-a-vehicle-door-structure-based-on-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13002.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">429</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">4747</span> Effect of Cantilever Sheet Pile Wall to Adjacent Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20A.%20Mohamed%20Aly">Ahmed A.

With the increasing rate of construction work in urban area, this problem is growing more significant and has become the cause of numerous legal disputes. This problem is investigated numerically in the present study using finite element method. Five-story reinforced concrete building rests on raft foundation is idealized as two dimensional model. The building is considered to be constructed adjacent to excavation affected by an adjacent excavation in medium sand. Excavation is supported using sheet pile wall. Two dimensional plane strain program PLAXIS is used in this study. 15 nodes triangular element is used to idealize soil with Mohr-Coulomb model. Five nodes isoperimetric beam element is used to idealize sheet pile and building. Interface element is used to represent the contact between beam element and soil. Two parameters were studied, the first is the foundation depth and the second is the building distance from the excavation. Nodal displacements and elements straining actions were obtained and studied from the analyzed finite element model results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=excavation" title="excavation">excavation</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20distance" title=" relative distance"> relative distance</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20stresses" title=" effective stresses"> effective stresses</a>, <a href="https://publications.waset.org/abstracts/search?q=lateral%20deformation" title=" lateral deformation"> lateral deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20depth" title=" relative depth"> relative depth</a> </p> <a href="https://publications.waset.org/abstracts/112507/effect-of-cantilever-sheet-pile-wall-to-adjacent-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112507.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">138</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">4746</span> Catalytic Production of Hydrogen and Carbon Nanotubes over Metal/SiO2 Core-Shell Catalyst from Plastic Wastes Gasification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wei-Jing%20Li">Wei-Jing Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Ren-Xuan%20Yang"> Ren-Xuan Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kui-Hao%20Chuang"> Kui-Hao Chuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Yen%20Wey"> Ming-Yen Wey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, plastic product and utilization are extensive and have greatly improved our life. Yet, plastic wastes are stable and non-biodegradable challenging issues to the environment. Waste-to-energy strategies emerge a promising way for waste management. This work investigated the co-production of hydrogen and carbon nanotubes from the syngas which was from the gasification of polypropylene. A nickel-silica core-shell catalyst was applied for syngas reaction from plastic waste gasification in a fixed-bed reactor. SiO2 were prepared through various synthesis solvents by Stöber process. Ni plays a role as modified SiO2 support, which were synthesized by deposition-precipitation method. Core-shell catalysts have strong interaction between active phase and support, in order to avoid catalyst sintering. Moreover, Fe or Co metal acts as promoter to enhance catalytic activity. The effects of calcined atmosphere, second metal addition, and reaction temperature on hydrogen production and carbon yield were examined. In this study, the catalytic activity and carbon yield results revealed that the Ni/SiO2 catalyst calcined under H2 atmosphere exhibited the best performance. Furthermore, Co promoted Ni/SiO2 catalyst produced 3 times more than Ni/SiO2 on carbon yield at long-term operation. The structure and morphological nature of the calcined and spent catalysts were examined using different characterization techniques including scanning electron microscopy, transmission electron microscopy, X-ray diffraction. In addition, the quality and thermal stability of the nano-carbon materials were also evaluated by Raman spectroscopy and thermogravimetric analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plastic%20wastes" title="plastic wastes">plastic wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title=" carbon nanotube"> carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=core-shell%20catalysts" title=" core-shell catalysts"> core-shell catalysts</a> </p> <a href="https://publications.waset.org/abstracts/40473/catalytic-production-of-hydrogen-and-carbon-nanotubes-over-metalsio2-core-shell-catalyst-from-plastic-wastes-gasification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40473.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">319</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">4745</span> Active Learning Based on Science Experiments to Improve Scientific Literacy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kunihiro%20Kamataki">Kunihiro Kamataki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, active learning based on simple science experiments was developed in a university class of the freshman, in order to improve their scientific literacy.

Nonlinear time history dynamic analysis with 3 near-field records are performed on them. In order to further understand the structural collapse behavior in the near field, the response of the structure at the moment of collapse especially the formation of plastic hinges is explored. The results revealed that the amplification of moment at top of the wall due to higher modes, the plastic hinge can form in the upper part of wall, even when designed and detailed for plastic hinging at the base only (according to ACI code).on the other hand, shear forces in excess of capacity design values can develop due to the contribution of the higher modes of vibration to dynamic response due to the near field can cause brittle shear or sliding failure modes. The past investigation on shear walls clearly shows the dual-hinge design concept is effective at reducing the effects of the second mode of response. An advantage of the concept is that, when combined with capacity design, it can result in relaxation of special reinforcing detailing in large portions of the wall. In this study, to investigate the implications of multi-design approach, 4 models with varies arrangement of hinge plastics at the base and height of the shear wall are considered. results base on time history analysis showed that the dual or multi plastic hinges approach can be useful in order to control the high moment and shear demand of higher mode effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=higher%20mode%20effect" title="higher mode effect">higher mode effect</a>, <a href="https://publications.waset.org/abstracts/search?q=Near-field%20earthquake" title=" Near-field earthquake"> Near-field earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20time%20history%20analysis" title=" nonlinear time history analysis"> nonlinear time history analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20plastic%20hinge%20design" title=" multi plastic hinge design"> multi plastic hinge design</a> </p> <a href="https://publications.waset.org/abstracts/22489/seismic-evaluation-of-multi-plastic-hinge-design-approach-on-rc-shear-wall-moment-frame-systems-against-near-field-earthquakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22489.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4743</span> Implementation of Traffic Engineering Using MPLS Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vishal%20H.%20Shukla">Vishal H.

Finite Element Method (FEM) is a powerful numerical method that has been used successfully for the solution of the existing problems in various scientific and engineering fields such as its application in CFD. Many algorithms have been expressed based on FEM, but none have been used in popular CFD software. In this section, full monopoly is according to Finite Volume Method (FVM) due to better efficiency and adaptability with the physics of problems in comparison with FEM. It doesn't seem that FEM could compete with FVM unless it was fundamentally changed. This paper shows those changes and its result will be a powerful method that has much better performance in all subjects in comparison with FVM and another computational method.

In this thesis analysis of the protection walls have been conducted to prevent the building damage from blast loads. These analyzes was carried out for two different types of wall, concrete and reinforced concrete. Analyses were carried out on four different thicknesses of each wall element. In each wall element the stresses and displacements of the exposed surface due to the detonation charge has been calculated. The limit shear stress and displacement of the wall element according to their material properties has been taken into account. As the result of the analyses the standoff distances and TNT equivalent amount has been determined. According to equivalent TNT amounts and standoff distances the structural response of the protective wall elements has been observed. These structural responses have been observed by ABAQUS finite element package. Explosion loads were brought into effect to the protective wall element models by using the ABAQUS / CONWEP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20loading" title="blast loading">blast loading</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20wave" title=" blast wave"> blast wave</a>, <a href="https://publications.waset.org/abstracts/search?q=TNT%20equivalent%20method" title=" TNT equivalent method"> TNT equivalent method</a>, <a href="https://publications.waset.org/abstracts/search?q=CONWEP" title=" CONWEP"> CONWEP</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=detonation" title=" detonation"> detonation</a> </p> <a href="https://publications.waset.org/abstracts/38734/structural-performance-of-prefabricated-concrete-and-reinforced-concrete-structural-walls-under-blast-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38734.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">439</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">4738</span> In Vitro Intestine Tissue Model to Study the Impact of Plastic Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashleigh%20Williams">Ashleigh Williams</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Micro- and nanoplastics’ (MNLPs) omnipresence and ecological accumulation is evident when surveying recent environmental impact studies. For example, in 2014 it was estimated that at least 52.3 trillion plastic microparticles are floating at sea, and scientists have even found plastics present remote Arctic ice and snow (5,6). Plastics have even found their way into precipitation, with more than 1000 tons of microplastic rain precipitating onto the Western United States in 2020. Even more recent studies evaluating the chemical safety of reusable plastic bottles found that hundreds of chemicals leached into the control liquid in the bottle (ddH2O, ph = 7) during a 24-hour time period. A consequence of the increased abundance in plastic waste in the air, land, and water every year is the bioaccumulation of MNLPs in ecosystems and trophic niches of the animal food chain, which could potentially cause increased direct and indirect exposure of humans to MNLPs via inhalation, ingestion, and dermal contact. Though the detrimental, toxic effects of MNLPs have been established in marine biota, much less is known about the potentially hazardous health effects of chronic MNLP ingestion in humans. Recent data indicate that long-term exposure to MNLPs could cause possible inflammatory and dysbiotic effects. However, toxicity seems to be largely dose-, as well as size-dependent. In addition, the transcytotic uptake of MNLPs through the intestinal epithelia in humans remain relatively unknown. To this point, the goal of the current study was to investigate the mechanisms of micro- and nanoplastic uptake and transcytosis of Polystyrene (PE) in human stem-cell derived, physiologically relevant in vitro intestinal model systems, and to compare the relative effect of particle size (30 nm, 100 nm, 500 nm and 1 µm), and concentration (0 µg/mL, 250 µg/mL, 500 µg/mL, 1000 µg/mL) on polystyrene MNLP uptake, transcytosis and intestinal epithelial model integrity. Observational and quantitative data obtained from confocal microscopy, immunostaining, transepithelial electrical resistance (TEER) measurements, cryosectioning, and ELISA cytokine assays of the proinflammatory cytokines Interleukin-6 and Interleukin-8 were used to evaluate the localization and transcytosis of polystyrene MNPs and its impact on epithelial integrity in human-derived intestinal in vitro model systems. The effect of Microfold (M) cell induction on polystyrene micro- and nanoparticle (MNP) uptake, transcytosis, and potential inflammation was also assessed and compared to samples grown under standard conditions. Microfold (M) cells, link the human intestinal system to the immune system and are the primary cells in the epithelium responsible for sampling and transporting foreign matter of interest from the lumen of the gut to underlying immune cells. Given the uptake capabilities of Microfold cells to interact both specifically and nonspecific to abiotic and biotic materials, it was expected that M- cell induced in vitro samples would have increased binding, localization, and potentially transcytosis of Polystyrene MNLPs across the epithelial barrier. Experimental results of this study would not only help in the evaluation of the plastic toxicity, but would allow for more detailed modeling of gut inflammation and the intestinal immune system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoplastics" title="nanoplastics">nanoplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=enteroids" title=" enteroids"> enteroids</a>, <a href="https://publications.waset.org/abstracts/search?q=intestinal%20barrier" title=" intestinal barrier"> intestinal barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title=" tissue engineering"> tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=microfold%20%28M%29%20cells" title=" microfold (M) cells"> microfold (M) cells</a> </p> <a href="https://publications.waset.org/abstracts/147076/in-vitro-intestine-tissue-model-to-study-the-impact-of-plastic-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147076.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">85</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">4737</span> Reliability Estimation of Bridge Structures with Updated Finite Element Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ekin%20Ozer">Ekin Ozer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assessment of structural reliability is essential for efficient use of civil infrastructure which is subjected hazardous events. Dynamic analysis of finite element models is a commonly used tool to simulate structural behavior and estimate its performance accordingly. However, theoretical models purely based on preliminary assumptions and design drawings may deviate from the actual behavior of the structure. This study proposes up-to-date reliability estimation procedures which engages actual bridge vibration data modifying finite element models for finite element model updating and performing reliability estimation, accordingly. The proposed method utilizes vibration response measurements of bridge structures to identify modal parameters, then uses these parameters to calibrate finite element models which are originally based on design drawings. The proposed method does not only show that reliability estimation based on updated models differs from the original models, but also infer that non-updated models may overestimate the structural capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake%20engineering" title="earthquake engineering">earthquake engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20vibrations" title=" engineering vibrations"> engineering vibrations</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20estimation" title=" reliability estimation"> reliability estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20health%20monitoring" title=" structural health monitoring"> structural health monitoring</a> </p> <a href="https://publications.waset.org/abstracts/90837/reliability-estimation-of-bridge-structures-with-updated-finite-element-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90837.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">223</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4736</span> An Implementation of Meshless Method for Modeling an Elastoplasticity Coupled to Damage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sendi%20Zohra">Sendi Zohra</a>, <a href="https://publications.waset.org/abstracts/search?q=Belhadjsalah%20Hedi"> Belhadjsalah Hedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Labergere%20Carl"> Labergere Carl</a>, <a href="https://publications.waset.org/abstracts/search?q=Saanouni%20Khemais"> Saanouni Khemais</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The modeling of mechanical problems including both material and geometric nonlinearities with Finite Element Method (FEM) remains challenging. Meshless methods offer special properties to get rid of well-known drawbacks of the FEM. The main objective of Meshless Methods is to eliminate the difficulty of meshing and remeshing the entire structure by simply insertion or deletion of nodes, and alleviate other problems associated with the FEM, such as element distortion, locking and others. In this study, a robust numerical implementation of an Element Free Galerkin Method for an elastoplastic coupled to damage problem is presented. Several results issued from the numerical simulations by a DynamicExplicit resolution scheme are analyzed and critically compared with Element Finite Method results. Finally, different numerical examples are carried out to demonstrate the efficiency of this method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage" title="damage">damage</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20explicit" title=" dynamic explicit"> dynamic explicit</a>, <a href="https://publications.waset.org/abstracts/search?q=elastoplasticity" title=" elastoplasticity"> elastoplasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=isotropic%20hardening" title=" isotropic hardening"> isotropic hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=meshless" title=" meshless"> meshless</a> </p> <a href="https://publications.waset.org/abstracts/46273/an-implementation-of-meshless-method-for-modeling-an-elastoplasticity-coupled-to-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46273.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">295</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">4735</span> B Spline Finite Element Method for Drifted Space Fractional Tempered Diffusion Equation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayan%20Chakraborty">Ayan Chakraborty</a>, <a href="https://publications.waset.org/abstracts/search?q=BV.%20Rathish%20Kumar"> BV. Rathish Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Off-late many models in viscoelasticity, signal processing or anomalous diffusion equations are formulated in fractional calculus. Tempered fractional calculus is the generalization of fractional calculus and in the last few years several important partial differential equations occurring in the different field of science have been reconsidered in this term like diffusion wave equations, Schr$\ddot{o}$dinger equation and so on. In the present paper, a time-dependent tempered fractional diffusion equation of order $\gamma \in (0,1)$ with forcing function is considered. Existence, uniqueness, stability, and regularity of the solution has been proved. Crank-Nicolson discretization is used in the time direction. B spline finite element approximation is implemented. Generally, B-splines basis are useful for representing the geometry of a finite element model, interfacing a finite element analysis program. By utilizing this technique a priori space-time estimate in finite element analysis has been derived and we proved that the convergent order is $\mathcal{O}(h²+T²)$ where $h$ is the space step size and $T$ is the time. A couple of numerical examples have been presented to confirm the accuracy of theoretical results. Finally, we conclude that the studied method is useful for solving tempered fractional diffusion equations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=B-spline%20finite%20element" title="B-spline finite element">B-spline finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20estimates" title=" error estimates"> error estimates</a>, <a href="https://publications.waset.org/abstracts/search?q=Gronwall%27s%20lemma" title=" Gronwall's lemma"> Gronwall's lemma</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=tempered%20fractional" title=" tempered fractional"> tempered fractional</a> </p> <a href="https://publications.waset.org/abstracts/99835/b-spline-finite-element-method-for-drifted-space-fractional-tempered-diffusion-equation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99835.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">192</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">4734</span> An Integrated Experimental and Numerical Approach to Develop an Electronic Instrument to Study Apple Bruise Damage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paula%20Pascoal-Faria">Paula Pascoal-Faria</a>, <a href="https://publications.waset.org/abstracts/search?q=R%C3%BAben%20Pereira"> Rúben Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Elodie%20Pinto"> Elodie Pinto</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Belbut"> Miguel Belbut</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Rosa"> Ana Rosa</a>, <a href="https://publications.waset.org/abstracts/search?q=In%C3%AAs%20Sousa"> Inês Sousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuno%20Alves"> Nuno Alves</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Apple bruise damage from harvesting, handling, transporting and sorting is considered to be the major source of reduced fruit quality, resulting in loss of profits for the entire fruit industry. The three factors which can physically cause fruit bruising are vibration, compression load and impact, the latter being the most common source of bruise damage. Therefore, prediction of the level of damage, stress distribution and deformation of the fruits under external force has become a very important challenge. In this study, experimental and numerical methods were used to better understand the impact caused when an apple is dropped from different heights onto a plastic surface and a conveyor belt. Results showed that the extent of fruit damage is significantly higher for plastic surface, being dependent on the height. In order to support the development of a biomimetic electronic device for the determination of fruit damage, the mechanical properties of the apple fruit were determined using mechanical tests. Preliminary results showed different values for the Young’s modulus according to the zone of the apple tested. Along with the mechanical characterization of the apple fruit, the development of the first two prototypes is discussed and the integration of the results obtained to construct the final element model of the apple is presented. This work will help to reduce significantly the bruise damage of fruits or vegetables during the entire processing which will allow the introduction of exportation destines and consequently an increase in the economic profits in this sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apple" title="apple">apple</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20damage" title=" fruit damage"> fruit damage</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20during%20crop%20and%20post-crop" title=" impact during crop and post-crop"> impact during crop and post-crop</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20characterization%20of%20the%20apple" title=" mechanical characterization of the apple"> mechanical characterization of the apple</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20evaluation%20of%20fruit%20damage" title=" numerical evaluation of fruit damage"> numerical evaluation of fruit damage</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20device" title=" electronic device"> electronic device</a> </p> <a href="https://publications.waset.org/abstracts/53452/an-integrated-experimental-and-numerical-approach-to-develop-an-electronic-instrument-to-study-apple-bruise-damage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53452.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">305</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">4733</span> Element Content in Some Wild Agaricus and Agrocybe Taxa from Marmara Region (Turkey)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murad%20Aydin%20%C5%9Eanda">Murad Aydin Şanda</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20H%C3%BCseyi%CC%87n%20Do%C4%9Fan"> Hasan Hüseyi̇n Doğan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Twenty-two element contents were analyzed in five wild Agaricus and Agrocybe taxa [Agaricus bresadolanus Bohus, Agaricus essettei Bon, Agaricus xanthoderma Genev.

The thermo-gravimetric analyzer was used to determine the thermal stability of the sample. An aerial yam sample of size 30 x 20 x 4 mm was cut with a mold designed for the purpose and dried in a convective dryer set at 4m/s fan speed and temperatures of 68.58 and 60.56°C. The volume shrinkage of the resultant dried sample was determined by immersing the sample in a toluene solution. The finite element analysis was done with PDE tools in Matlab 2015. Seven kinetic models were employed to model the drying process. The result obtained revealed three regions in the thermogravimetric analysis (TGA) profile of aerial yam. The maximum thermal degradation rates of the sample occurred at 432.7°C. The effective thermal diffusivity of the sample increased as the temperature increased from 60.56°C to 68.58°C. The finite element prediction of moisture content of aerial yam at an air temperature of 68.58°C and 60.56°C shows R² of 0.9663 and 0.9155, respectively. There was a good agreement between the finite element predicted moisture content and the measured moisture content, which is indicative of a highly reliable finite element model developed. The result also shows that the best kinetic model for the aerial yam under the given drying conditions was the Logarithmic model with a correlation coefficient of 0.9991. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerial%20yam" title="aerial yam">aerial yam</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=convective" title=" convective"> convective</a>, <a href="https://publications.waset.org/abstracts/search?q=effective" title=" effective"> effective</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusivity" title=" diffusivity"> diffusivity</a> </p> <a href="https://publications.waset.org/abstracts/148796/thermophysical-properties-and-kinetic-study-of-dioscorea-bulbifera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148796.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">153</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">4730</span> The Effect of Jet Grouting on the Behavior of Strip Footing Adjacent to Slope Crest</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20M.%20El-Tuhami">Ahmed M.

Five nodes isoperimetric beam element is used to idealize stripe footing. Interface element is used to represent the contact between beam element and soil. Two parameters were studied, the first is the foundation depth and the second is the Stripe footing distance from the slope crest. Settlement and horizontal displacement of strip footing were obtained and studied from the analyzed finite element model results. The reduction influence of jet grouting on footing displacement were studied and investigated. The results indicate that the inclusion of jet grouting under strip footing adjacent to slope crest has significant effect in improving the response of the strip footing and the slope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=strip%20footing" title="strip footing">strip footing</a>, <a href="https://publications.waset.org/abstracts/search?q=jet%20grouting" title=" jet grouting"> jet grouting</a>, <a href="https://publications.waset.org/abstracts/search?q=slope" title=" slope"> slope</a>, <a href="https://publications.waset.org/abstracts/search?q=PLAXIS" title=" PLAXIS"> PLAXIS</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20distance" title=" relative distance"> relative distance</a> </p> <a href="https://publications.waset.org/abstracts/6092/the-effect-of-jet-grouting-on-the-behavior-of-strip-footing-adjacent-to-slope-crest" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6092.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">475</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">4729</span> Use of Slab Method, Throwing and Press Mold in Making Ceramic Holders for Offices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20P.%20Doku-Asare">E.

Essuman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The materials used for the production of holders are mainly metals and plastic, and these materials are difficult and expensive to process; therefore, the need to explore other materials such as clay for the production of holders. Clay is a viable material for the production of holders due to its plastic nature. Using ceramic materials as a medium for the production of holders does not only serve its purpose but also economically cheaper since the material is mined in Ghana. The study also examines the aesthetic nature of the holders due to the properties found in the material used. Six holders were chosen and were made in a manner that would not take a lot of space. They are Pin holders, Paper holders, Penholders, Paperweight and Umbrella holders. The production technique employed in the execution of this project were the slab method, throwing, and press mold. Results indicated that ceramic holders are durable and long-lasting and can serve the purpose of metallic and plastic holders. The study also found that clay holders are durable due to the fact that clay is from a natural source which ensures permanence and resistance to stress. It is recommended that press molds be used in the production of holders. Clay holders last longer due to the useful properties of clay including very high hardness and strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramics" title="ceramics">ceramics</a>, <a href="https://publications.waset.org/abstracts/search?q=interior%20design" title=" interior design"> interior design</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20technique" title=" production technique"> production technique</a> </p> <a href="https://publications.waset.org/abstracts/92757/use-of-slab-method-throwing-and-press-mold-in-making-ceramic-holders-for-offices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92757.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4728</span> A Composite Beam Element Based on Global-Local Superposition Theory for Prediction of Delamination in Composite Laminates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles%20Mota%20Possatti%20J%C3%BAnior">Charles Mota Possatti Júnior</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9%20Schwanz%20de%20Lima"> André Schwanz de Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Maur%C3%ADcio%20Vicente%20Donadon"> Maurício Vicente Donadon</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfredo%20Rocha%20de%20Faria"> Alfredo Rocha de Faria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An interlaminar damage model is combined with a beam element formulation based on global-local superposition to assess delamination in composite laminates. The variations in the mechanical properties in the laminate, generated by the presence of delamination, are calculated as a function of the displacements in the interface layers. The global-local superposition of displacement fields ensures the zig-zag behaviour of stresses and displacement, and the number of degrees of freedom (DOFs) is independent of the number of layers. The displacements and stresses are calculated as a function of DOFs commonly used in traditional beam elements. Finally, the finite element(FE) formulation is extended to handle cases of different thicknesses, and then the FE model predictions are compared with results obtained from analytical solutions and commercial finite element codes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delamination" title="delamination">delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=global-local%20superposition%20theory" title=" global-local superposition theory"> global-local superposition theory</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20beam%20element" title=" single beam element"> single beam element</a>, <a href="https://publications.waset.org/abstracts/search?q=zig-zag" title=" zig-zag"> zig-zag</a>, <a href="https://publications.waset.org/abstracts/search?q=interlaminar%20damage%20model" title=" interlaminar damage model"> interlaminar damage model</a> </p> <a href="https://publications.waset.org/abstracts/157413/a-composite-beam-element-based-on-global-local-superposition-theory-for-prediction-of-delamination-in-composite-laminates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157413.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">118</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">4727</span> Determination of Optimal Stress Locations in 2D–9 Noded Element in Finite Element Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nishant%20Shrivastava">Nishant Shrivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20K.%20Sehgal"> D. K. Sehgal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Finite Element Technique nodal stresses are calculated through displacement as nodes. In this process, the displacement calculated at nodes is sufficiently good enough but stresses calculated at nodes are not sufficiently accurate. Therefore, the accuracy in the stress computation in FEM models based on the displacement technique is obviously matter of concern for computational time in shape optimization of engineering problems. In the present work same is focused to find out unique points within the element as well as the boundary of the element so, that good accuracy in stress computation can be achieved. Generally, major optimal stress points are located in domain of the element some points have been also located at boundary of the element where stresses are fairly accurate as compared to nodal values. Then, it is subsequently concluded that there is an existence of unique points within the element, where stresses have higher accuracy than other points in the elements. Therefore, it is main aim is to evolve a generalized procedure for the determination of the optimal stress location inside the element as well as at the boundaries of the element and verify the same with results from numerical experimentation. The results of quadratic 9 noded serendipity elements are presented and the location of distinct optimal stress points is determined inside the element, as well as at the boundaries. The theoretical results indicate various optimal stress locations are in local coordinates at origin and at a distance of 0.577 in both directions from origin. Also, at the boundaries optimal stress locations are at the midpoints of the element boundary and the locations are at a distance of 0.577 from the origin in both directions. The above findings were verified through experimentation and findings were authenticated. For numerical experimentation five engineering problems were identified and the numerical results of 9-noded element were compared to those obtained by using the same order of 25-noded quadratic Lagrangian elements, which are considered as standard. Then root mean square errors are plotted with respect to various locations within the elements as well as the boundaries and conclusions were drawn. After numerical verification it is noted that in a 9-noded element, origin and locations at a distance of 0.577 from origin in both directions are the best sampling points for the stresses. It was also noted that stresses calculated within line at boundary enclosed by 0.577 midpoints are also very good and the error found is very less. When sampling points move away from these points, then it causes line zone error to increase rapidly. Thus, it is established that there are unique points at boundary of element where stresses are accurate, which can be utilized in solving various engineering problems and are also useful in shape optimizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20elements" title="finite elements">finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=Lagrangian" title=" Lagrangian"> Lagrangian</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20stress%20location" title=" optimal stress location"> optimal stress location</a>, <a href="https://publications.waset.org/abstracts/search?q=serendipity" title=" serendipity "> serendipity </a> </p> <a href="https://publications.waset.org/abstracts/125656/determination-of-optimal-stress-locations-in-2d-9-noded-element-in-finite-element-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125656.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">105</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">4726</span> Evaluation of Regional Anaesthesia Practice in Plastic Surgery: A Retrospective Cross-Sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samar%20Mousa">Samar Mousa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryan%20Kerstein"> Ryan Kerstein</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohanad%20Adam"> Mohanad Adam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Regional anaesthesia has been associated with favourable outcomes in patients undergoing a wide range of surgeries. Beneficial effects have been demonstrated in terms of postoperative respiratory and cardiovascular endpoints, 7-day survival, time to ambulation and hospital discharge, and postoperative analgesia. Our project aimed at assessing the regional anaesthesia practice in the plastic surgery department of Buckinghamshire trust and finding out ways to improve the service in collaboration with the anaesthesia team. It is a retrospective study associated with a questionnaire filled out by plastic surgeons and anaesthetists to get the full picture behind the numbers. The study period was between 1/3/2022 and 23/5/2022 (12 weeks). The operative notes of all patients who had an operation under plastic surgery, whether emergency or elective, were reviewed. The criteria of suitable candidates for the regional block were put by the consultant anaesthetists as follows: age above 16, single surgical site (arm, forearm, leg, foot), no drug allergy, no pre-existing neuropathy, no bleeding disorders, not on ant-coagulation, no infection to the site of the block. For 12 weeks, 1061 operations were performed by plastic surgeons. Local cases were excluded leaving 319 cases. Of the 319, 102 patients were suitable candidates for regional block after applying the previously mentioned criteria. However, only seven patients had their operations under the regional block, and the rest had general anaesthesia that could have been easily avoided. An online questionnaire was filled out by both plastic surgeons and anaesthetists of different training levels to find out the reasons behind the obvious preference for general over regional anaesthesia, even if this was against the patients’ interest. The questionnaire included the following points: training level, time taken to give GA or RA, factors that influence the decision, percentage of RA candidates that had GA, reasons behind this percentage, recommendations. Forty-four clinicians filled out the questionnaire, among which were 23 plastic surgeons and 21 anaesthetists. As regards the training level, there were 21 consultants, 4 associate specialists, 9 registrars, and 10 senior house officers. The actual percentage of patients who were good candidates for RA but had GA instead is 93%. The replies estimated this percentage as between 10-30%. 29% of the respondents thought that this percentage is because of surgeons’ preference to have GA rather than RA for their operations without medical support for the decision. 37% of the replies thought that anaesthetists prefer giving GA even if the patient is a suitable candidate for RA. 22.6% of the replies thought that patients refused to have RA, and 11.3% had other causes. The recommendations were in 5 main accesses, which are protocols and pathways for regional blocks, more training opportunities for anaesthetists on regional blocks, providing a separate block room in the hospital, better communication between surgeons and anaesthetists, patient education about the benefits of regional blocks. <p class="card-text"><strong>Keywords:</strong> <a
