Impurities inherent in reduction process also depend on the quality of the raw material used. Among the applications of the silicon, it is used as a substrate for the photovoltaic conversion of solar energy and this conversion is wider as the purity of the substrate is important. Research is being done where the purpose is looking for new methods of manufacturing and purification of silicon, as well as new materials that can be used as substrates for the photovoltaic conversion of light energy. In this research, the technique of production of silicon in an induction furnace, using a high vacuum for fusion. Diatomaceous Silica (SiO2) used is 99 mass% initial purities, the carbon used is 6N of purity and the particle size of 63μm as starting materials. The final achieved purity of the material was above 50% by mass. These results demonstrate that this method is a technically reliable, and allows obtaining a better return on the amount 50% of silicon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20furnaces" title="induction furnaces">induction furnaces</a>, <a href="https://publications.waset.org/abstracts/search?q=amorphous%20silica" title=" amorphous silica"> amorphous silica</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20microstructure" title=" carbon microstructure"> carbon microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon" title=" silicon"> silicon</a> </p> <a href="https://publications.waset.org/abstracts/47448/the-manufacturing-of-metallurgical-grade-silicon-from-diatomaceous-silica-by-an-induction-furnace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47448.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">404</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">68</span> Preparation of Amorphous silica from Algerian Diatomite and Its Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Medeghri">S.

The sodium silicate is commonly used as precursor in silica gel diatomite preparation. In this study, the preparation of sodium silicate is preceded by acid washing of raw diatomite; the acid is then slowly added to precipitate silica at different pH values to obtain silica gel. The silica gel is characterized by EDX, ICP-MS and XRD. The EDX revels that the purity of silica from diatom is 98% after purification compared to raw diatom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatomite" title="diatomite">diatomite</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20cleaning" title=" acid cleaning"> acid cleaning</a>, <a href="https://publications.waset.org/abstracts/search?q=dissolution" title=" dissolution"> dissolution</a>, <a href="https://publications.waset.org/abstracts/search?q=amorphous%20silica" title=" amorphous silica"> amorphous silica</a>, <a href="https://publications.waset.org/abstracts/search?q=purity" title=" purity"> purity</a> </p> <a href="https://publications.waset.org/abstracts/27238/preparation-of-amorphous-silica-from-algerian-diatomite-and-its-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27238.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">576</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> A Novel Co-Culture System for the Cementoblastic Differentiation of SHED</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20Farea">Manal Farea</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20Husein"> Adam Husein</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20S.%20Halim"> Ahmad S.

Regeneration of cementum is very essential for the perforation repair. The aim of this study was to investigate the role of Hertwig's epithelial root sheath (HERS) cells on the cementogenic differentiation of stem cells derived from human exfoliated deciduous teeth (SHED) in the presence of chitosan scaffold-TGFβ1. HERS cells were isolated and characterized then co-cultured with SHED with/without chitosan scaffold-TGFβ1. SHED proliferation was assessed by PrestoBlue. Alkaline phosphatase activity, mineralization behaviour and gene/protein expression of cemento/osteoblast phenotype of SHED were evaluated. Results of the present study showed that HERS cells in association with chitosan-TGFβ1 enhanced proliferation and cemento/osteogenic differentiation of SHED. Our novel co-culture system confirmed the potential effect of HERS cells to stimulate the differentiation of SHED along the cementoblastic lineage which was triggered in the presence of chitosan-TGFβ1. This approach possesses a novel therapeutic strategy for future endodontic perforation and periodontitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cementogenesis" title="cementogenesis">cementogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=co-culture%20system" title=" co-culture system"> co-culture system</a>, <a href="https://publications.waset.org/abstracts/search?q=HERS" title=" HERS"> HERS</a>, <a href="https://publications.waset.org/abstracts/search?q=SHED" title=" SHED"> SHED</a> </p> <a href="https://publications.waset.org/abstracts/34836/a-novel-co-culture-system-for-the-cementoblastic-differentiation-of-shed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34836.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">542</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Evaluation of Antimicrobial Activity of Different Dithiolethiones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zehour%20Rahmani">Zehour Rahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Messouda%20Dekmouche"> Messouda Dekmouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hadjadj"> Mohamed Hadjadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Saidi"> Mokhtar Saidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last decades of the nineteenth century, the study of disease – causing microorganisms became concentrated on bacteria and largely institutionalized.

The dam building industry is a great service to mankind in the use of water and land resources. If they build the dam in a suitable place, they will prevent floods. The water that collects behind the dam and in the dam's lake and reservoir is a valuable reserve for drinking by people and animals. Dry agricultural lands are also irrigated with this water.

An equation has been proposed to predict wear rates and describe sliding wear caused by Corundum ball on the studied material. The results show how the wear rate, measured by mass loss, varies in the range of (0.6 – 3.8 x E-6 mm3/Nm) with normal sliding distance under various test conditions; it increases with increasing load and rapidly with speed.

The impact of the Soret and Coriolis force on the onset of stationary convection in a system is analysed with respect to various Binary fluid parameters and presented graphically.

In this way, all sea, land, and air routes are considered as roads. Road construction is an operation to create a road on the ground between 2 points with a specified width, which includes works such as subgrade, paving, placing tables, and traffic signs on the road. In this article, the stages of road construction are explained from the beginning to the end. Road construction is generally done in the construction of rural, urban, and inter-city roads, and according to the special conditions of this area, the precision of engineers in its design and calculations is very important. For example, if the design of a road does not pay enough attention to the way the road curves, there will undoubtedly be countless accidents. Also, adjusting the road surface and its durability and uniformity are among the things that engineers solve according to the upcoming obstacles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=road%20construction" title="road construction">road construction</a>, <a href="https://publications.waset.org/abstracts/search?q=surveying" title=" surveying"> surveying</a>, <a href="https://publications.waset.org/abstracts/search?q=freeway" title=" freeway"> freeway</a>, <a href="https://publications.waset.org/abstracts/search?q=pavement" title=" pavement"> pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=excavator" title=" excavator"> excavator</a> </p> <a href="https://publications.waset.org/abstracts/173669/stabilized-earth-roads-construction-and-its-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173669.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">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Preserving Privacy in Workflow Delegation Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noha%20Nagy">Noha Nagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoda%20Mokhtar"> Hoda Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20El%20Sherkawi"> Mohamed El Sherkawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The popularity of workflow delegation models and the increasing number of workflow provenance-aware systems motivate the need for finding more strict delegation models. Such models combine different approaches for enhanced security and respecting workflow privacy. Although modern enterprises seek conformance to workflow constraints to ensure correctness of their work, these constraints pose a threat to security, because these constraints can be good seeds for attacking privacy even in secure models. This paper introduces a comprehensive Workflow Delegation Model (WFDM) that utilizes provenance and workflow constraints to prevent malicious delegate from attacking workflow privacy as well as extending the delegation functionalities. In addition, we argue the need for exploiting workflow constraints to improve workflow security models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=workflow%20delegation%20models" title="workflow delegation models">workflow delegation models</a>, <a href="https://publications.waset.org/abstracts/search?q=secure%20workflow" title=" secure workflow"> secure workflow</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20privacy" title=" workflow privacy"> workflow privacy</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20provenance" title=" workflow provenance"> workflow provenance</a> </p> <a href="https://publications.waset.org/abstracts/47106/preserving-privacy-in-workflow-delegation-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47106.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">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Buckling Behavior of FGM Plates Using a Simplified Shear Deformation Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Bouazza">Mokhtar Bouazza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the simplified theory will be used to predict the thermoelastic buckling behavior of rectangular functionally graded plates.

Temperature prgrammed reduction (TPR) of Co-Al-LDH showed reduction peaks at lower temperature which indicates the ease reducibility of this particular sample. The thermal behaviour was studied using thermal graviemetric technique (TG), and the BET-surface area was determined using N2 physisorption at -196°C. The C-C coupling reaction was carried out over all the investigated catalysts. The Mg–Al LDH catalyst without Co ions is inactive, but the isomorphic substitution of Mg by Co ions (Co:Mg:Al = 1.5:1.5:1) in the cationic sheet resulted in 88% conversion of iodobenzene under reflux.

The resulting zirconia nanotubes (ZNTs) were then characterized using various techniques, including UV-vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). The XRD diffraction pattern confirmed that the ZNTs were crystalline, with a predominant texture along the [111] direction, indicating that the majority of the phase was cubic. TEM images revealed that most of the nanotubes were vertically aligned and self-organized, with diameters ranging from 32.9 to 38.8 nm and wall thicknesses between 3.0 and 7.3 nm. Additionally, the synthesized ZNTs had a length-to-width ratio of 235, which closely matches the ratio of 240 observed in another study where anodization was not used. This study demonstrates that a specific phase of zirconia nanotube can be successfully synthesized, with promising potential applications in catalysis and other areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zirconia%20nanotubes" title="zirconia nanotubes">zirconia nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=anodization" title=" anodization"> anodization</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=cubic%20phase" title=" cubic phase"> cubic phase</a> </p> <a href="https://publications.waset.org/abstracts/192982/anodization-assisted-synthesis-of-shape-controlled-cubic-zirconia-nanotubes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192982.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">19</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> 2D RF ICP Torch Modelling with Fluid Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Labiod">Mokhtar Labiod</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Ikhlef"> Nabil Ikhlef</a>, <a href="https://publications.waset.org/abstracts/search?q=Keltoum%20Bouherine"> Keltoum Bouherine</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Leroy"> Olivier Leroy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A numerical model for the radio-frequency (RF) Argon discharge chamber is developed to simulate the low pressure low temperature inductively coupled plasma.

Electric and magnetic fields inside the discharge chamber are evaluated by solving a magnetic vector potential equation. To start with, the equations of the ideal magnetohydrodynamics theory will be presented describing the basic behaviour of magnetically confined plasma and equations are discretized with finite element method in cylindrical coordinates. The discharge chamber is assumed to be axially symmetric and the plasma is treated as a compressible gas. Plasma generation due to ionization is added to the continuity equation. Magnetic vector potential equation is solved for the electromagnetic fields. A strong dependence of the plasma properties on the discharge conditions and the gas temperature is obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct-coupled%20model" title="direct-coupled model">direct-coupled model</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetohydrodynamic" title=" magnetohydrodynamic"> magnetohydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20torch%20simulation" title=" plasma torch simulation"> plasma torch simulation</a> </p> <a href="https://publications.waset.org/abstracts/38779/2d-rf-icp-torch-modelling-with-fluid-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38779.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">434</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Micro-CT Assessment of Fracture Healing in Androgen-Deficient Osteoporosis Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20N.%20Shuid">Ahmad N.

In this study, micro-CT was used to assess the fracture healing of orchidectomised rats, an androgen-deficient osteoporosis model. The effect of testosterone (hormone replacement) on fracture healing was also assessed with micro-CT. The rats were grouped into orchidectomised-control (ORX), sham-operated (SHAM), and orchidectomised; and injected with testosterone intramuscularly once weekly (TEN). Treatment duration was six weeks. The fracture was induced and fixed with plates and screws in the right tibia of all the rats. An in vitro micro-CT was used to scan the fracture callus area which consisted of 100 axial slices above and below fracture line. The analysis has shown that micro-CT was able to detect a significant difference in the fracture healing rate of ORX and TEN groups. In conclusion, micro-CT can be used to assess fracture healing in androgen-deficient osteoporosis. This imaging tool can be used to test agents that influence fracture healing in the androgen-deficient model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=androgen" title="androgen">androgen</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=orchidectomy" title=" orchidectomy"> orchidectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoporosis" title=" osteoporosis "> osteoporosis </a> </p> <a href="https://publications.waset.org/abstracts/33626/micro-ct-assessment-of-fracture-healing-in-androgen-deficient-osteoporosis-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33626.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">545</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Identification of Factors Influencing Costs in Green Projects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazirah%20Zainul%20Abidin">Nazirah Zainul Abidin</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Zahirah%20Mokhtar%20Azizi"> Nurul Zahirah Mokhtar Azizi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cost has always been the leading concern in green building development. The perception that construction cost for green building is higher than conventional buildings has only made the discussion of green building cost more difficult. Understanding the factors that will influence the cost of green construction is expected to shed light into what makes green construction more or at par with conventional projects, or perhaps, where cost can be optimised. This paper identifies the elements of cost before shifting the attention to the influencing factors. Findings from past studies uncovered various factors related to cost which are grouped into five focal themes i.e. awareness, knowledge, financial, technical, and government support. A conceptual framework is produced in a form of a flower diagram indicating the cost influencing factors of green building development. These factors were found to be both physical and non-physical aspects of a project. The framework provides ground for the next stage of research that is to further explore how these factors influence the project cost and decision making. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20project" title="green project">green project</a>, <a href="https://publications.waset.org/abstracts/search?q=factors%20influencing%20cost" title=" factors influencing cost"> factors influencing cost</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20cost" title=" hard cost"> hard cost</a>, <a href="https://publications.waset.org/abstracts/search?q=soft%20cost" title=" soft cost"> soft cost</a> </p> <a href="https://publications.waset.org/abstracts/49827/identification-of-factors-influencing-costs-in-green-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49827.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">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Antioxidant Activity and Correlation of Free Phenolic Content with the DPPH Radical Scavenging and Reducing Power Activity of Date Palm (Phoenix dactylifera L.) from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheyma%20Bensaci">Cheyma Bensaci</a>, <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Saidi"> Mokhtar Saidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Ghiaba"> Zineb Ghiaba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The first objective of this study is to determine the phenolic contents and antioxidant capacities of three different varieties of date palm (Phoenix dactylifera L.) fruit (DPF) from Algeria were using three different solvents.

We are fortunate that a huge number of metal artifacts from the industry of Egypt and Syria of this period have come down to us, many of which are preserved in Egyptian and international museums as well as private collections. Characterized by great diversity in its forms, sizes and functions, including the decorative designs executed on them, the artifacts reflected the extent of artistic creativity that characterized the arts in the two Mamluk period. This research paper aims to study three copper dishes from the Mamluk Circassian period and the rare documentary texts on them that have not been previously studied. These dishes date back to different decades from the 9th AH/15 AD century. One of them bears the name of Sultan Al-Muayyad Shaikh, and the second is the name of one of the great Mamluk princes in the Mamluk Circassian period, Prince Yashbak min Mahdi. The third dish is attributed to Prince Jan Balat Al-Ashrafie. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metalwork" title="metalwork">metalwork</a>, <a href="https://publications.waset.org/abstracts/search?q=dishes" title=" dishes"> dishes</a>, <a href="https://publications.waset.org/abstracts/search?q=decorative" title=" decorative"> decorative</a>, <a href="https://publications.waset.org/abstracts/search?q=calligraphy" title=" calligraphy"> calligraphy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamluk%20Arts" title=" Mamluk Arts"> Mamluk Arts</a> </p> <a href="https://publications.waset.org/abstracts/167273/an-artistic-study-of-three-rare-tennded-copper-dishes-from-the-mamluk-circassian-period-784-923-ah-1382-1517-ce" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167273.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">48</span> Study of Physico-Chimical Properties of a Silty Soil </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moulay%20Sma%C3%AFne%20Ghembaza">Moulay Smaïne Ghembaza</a>, <a href="https://publications.waset.org/abstracts/search?q=Mokhtar%20Dadouch"> Mokhtar Dadouch</a>, <a href="https://publications.waset.org/abstracts/search?q=Nour-Said%20Ikhlef"> Nour-Said Ikhlef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil treatment is to make use soil that does not have the characteristics required in a given context.

To remedy this, firstly, we were trying to improve the Proctor Standard characteristics of this material by mechanical treatment increasing the compaction energy. Then, by a chemical treatment, adding some cement dosages, our results show that this material classified A1h a increase maximum dry density and a reduction in the water content of compaction. A comparative study is made on the optimal properties of the material between the two modes of treatment. On the other hand, after treatment, one finds a decrease in the plasticity index and the methylene blue value. This material exhibits a change of class. Therefore, soil class CL turned into a soil class composed CL-ML (Silt of low plasticity).

There are many different types of bridges, each of which is designed to perform a specific function. This article introduces the concept, history, components, uses, types, construction methods, selected factors, damage factors and principles of bridge maintenance. A bridge is a structure to cross a passage such as a water, valley or road without blocking another path underneath. This structure makes it possible to pass obstacles that are difficult or impossible to pass. There are different designs for bridge construction, each of which is used for a particular function and condition. In the old definition, a bridge is an arch over a river, valley, or any type of passage that makes traffic possible. But today, in the topic of urban management, the bridge is considered as a structure to cross physical barriers, so that while using space (not just the surface of the earth), it can facilitate the passage and access to places. The useful life of bridges may be between 30 and 80 years depending on the location and the materials used. But with proper maintenance and improvement, their life may last for hundreds of years. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge" title="bridge">bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20construction" title=" road construction"> road construction</a>, <a href="https://publications.waset.org/abstracts/search?q=surveying" title=" surveying"> surveying</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation" title=" transportation"> transportation</a> </p> <a href="https://publications.waset.org/abstracts/173987/bridge-construction-and-type-of-bridges-and-their-construction-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173987.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">512</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Application of Artificial Neural Network in Initiating Cleaning Of Photovoltaic Solar Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Mokhtar">Mohamed Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20F.%20Shaaban"> Mostafa F.

The accumulation of dust on the solar panels significantly degrades output from these panels. Hence, solar PV panels have to be cleaned manually or using costly automated cleaning methods. This paper focuses on initiating cleaning actions when required to reduce maintenance costs. The cleaning actions are triggered only when the dust level exceeds a threshold value. The amount of dust accumulated on the PV panels is estimated using an artificial neural network (ANN). Experiments are conducted to collect the required data, which are used in the training of the ANN model. Then, this ANN model will be fed by the output power from solar panels, ambient temperature, and solar irradiance, and thus, it will be able to estimate the amount of dust accumulated on solar panels at these conditions. The model was tested on different case studies to confirm the accuracy of the developed model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=dust" title=" dust"> dust</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20panels" title=" PV panels"> PV panels</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/131092/application-of-artificial-neural-network-in-initiating-cleaning-of-photovoltaic-solar-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131092.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">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Total Phenols, Total Flavonoids Contents and Free Radical Scavenging Activity of Seeds Extracts of Lawsonia alba (henna) from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rekia.%20Cherbi">Rekia.

The interpretation of subsurface were improve by combining inversion data from both methods by influence each other models using closure coupling; thus, by implementing both methods to support each other which could improve the subsurface interpretation. These methods were applied on a field dataset from a pre-investigation for archeology in finding the ancient river. There were no major changes in the inverted model by combining data inversion for this archetype which probably due to complex geology. The combine data analysis provides an additional technique for interpretation such as an alluvium, which can have strong influence on the ancient river findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ancient%20river" title="ancient river">ancient river</a>, <a href="https://publications.waset.org/abstracts/search?q=combine%20inversion" title=" combine inversion"> combine inversion</a>, <a href="https://publications.waset.org/abstracts/search?q=resistivity" title=" resistivity"> resistivity</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20refraction" title=" seismic refraction"> seismic refraction</a> </p> <a href="https://publications.waset.org/abstracts/70821/integration-of-resistivity-and-seismic-refraction-using-combine-inversion-for-ancient-river-findings-at-sungai-batu-lembah-bujang-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70821.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">334</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> The Effect of Mgo and Rubber Nanofillers on Electrical Treeing Characteristic of XLPE Based Nanocomposites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nur%20Amira%20nor%20Arifin">Nur Amira nor Arifin</a>, <a href="https://publications.waset.org/abstracts/search?q=Tashia%20Marie%20Anthony"> Tashia Marie Anthony</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Ruzlin%20Mokhtar"> Mohd Ruzlin Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Huzainie%20Shafi%20Abd%20Halim"> Huzainie Shafi Abd Halim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cross-linked polyethylene (XLPE) material is being used as the cable insulation for the past decades due to its higher working temperature of 90 ˚C and some other advantages. However, the use of XLPE as an insulating material for underground distribution cables may have subjected to the unforeseeable weather and uncontrollable environmental condition. These unfavorable condition when combine with high electric field may lead to the initiation and growth of water tree in XLPE insulation. There are several studies on numerous nanofillers incorporate into polymer matrix to hinder the growth of tree propagation. Hence, in this study aims to investigate the effect of MgO and rubber nanofillers at different concentration on the electrical tree of XLPE. The nanofillers and XLPE were mixed and later extruded. After extrusion, the material were then fabricated into the desired shape for experimental purposes. The result shows that the electrical tree propagation of XLPE filled with optimize concentration of nanofillers were much slower compared to pure XLPE.

In this work, fluorescence spectroscopy, electrospray-ionization mass spectrometry (ESI-MS), and HNMR were used to investigate and characterize the inclusion complexes of IMA with the cyclodextrins in solutions. The solid-state complexes were obtained by freeze-drying and were characterized by Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (PXRD). The most predominant complexes of IMA with both hosts are the 1:1 guest: host complexes. The association constants of IMA-HP β-CD and IMA-HP γ -CD were 115 and 215 L mol⁻¹, respectively. Molecular dynamic (MD) simulations were used to monitor the mode of inclusion and also to investigate the stability of these complexes in aqueous media at atomistic levels. The results obtained have indicated that these inclusion complexes are highly stable in aqueous media, thereby corroborating the experimental results. Additionally, it has been demonstrated that in addition to hydrophobic interactions and van der Waals interactions the presence of hydrogen bonding interactions of the type H---O and CH---O between the guest and the host have enhanced the stability of these complexes remarkably. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=imazapyr" title="imazapyr">imazapyr</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion%20complex" title=" inclusion complex"> inclusion complex</a>, <a href="https://publications.waset.org/abstracts/search?q=herbicides" title=" herbicides"> herbicides</a>, <a href="https://publications.waset.org/abstracts/search?q=2-hydroxypropyl-%CE%B2%2F%CE%B3-cyclodextrin" title=" 2-hydroxypropyl-β/γ-cyclodextrin"> 2-hydroxypropyl-β/γ-cyclodextrin</a> </p> <a href="https://publications.waset.org/abstracts/86839/investigations-of-inclusion-complexes-of-imazapyr-with-2-hydroxypropylvgh-cyclodextrin-experimental-and-molecular-modeling-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86839.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">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Modelling and Optimization of Laser Cutting Operations </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hany%20Mohamed%20Abdu">Hany Mohamed Abdu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hassan%20Gadallah"> Mohamed Hassan Gadallah</a>, <a href="https://publications.waset.org/abstracts/search?q=El-Giushi%20Mokhtar"> El-Giushi Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yehia%20Mahmoud%20Ismail"> Yehia Mahmoud Ismail </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laser beam cutting is one nontraditional machining process. This paper optimizes the parameters of Laser beam cutting machining parameters of Stainless steel (316L) by considering the effect of input parameters viz. power, oxygen pressure, frequency and cutting speed. Statistical design of experiments are carried in three different levels and process responses such as 'Average kerf taper (Ta)' and 'Surface Roughness (Ra)' are measured accordingly. A quadratic mathematical model (RSM) for each of the responses is developed as a function of the process parameters. Responses predicted by the models (as per Taguchi’s L27 OA) are employed to search for an optimal parametric combination to achieve desired yield of the process. RSM models are developed for mean responses, S/N ratio, and standard deviation of responses. Optimization models are formulated as single objective problem subject to process constraints. Models are formulated based on Analysis of Variance (ANOVA) using MATLAB environment.

As the world comes together and races to fulfil the 17 United Nations’ sustainable development goals (SDGs) by the year 2030, our educational curricula and landscapes simultaneously evolve to integrate lessons and opportunities for sustainable development and sustainability to redefine our university education and set the trajectory for our young people to take the lead in co-creating solutions for a better world. In this paper, initiatives and projects that revolved around themes of sustainable development and sustainability in a young university in Singapore are discussed. These initiatives and projects were curated by a new centre in the university that focuses on community leadership, social innovation, and service learning and was led by the university’s academic staff.
