For raison, response surface methodology (RMS) is used to determine the influence of each technological parameter. A full factorial design (L27) is chosen for the experiments, and the ANOVA is used in order to evaluate the influence of the technological cutting parameters namely; cutting speed (Vc), feed per tooth, and depth of cut (ap) on the out-put responses. The results reveal that (Ra) is mostly influenced by (fz) and (Fc) is found considerably affected by (ap). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=austenitic%20stainless%20steel" title="austenitic stainless steel">austenitic stainless steel</a>, <a href="https://publications.waset.org/abstracts/search?q=ANOVA" title=" ANOVA"> ANOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=coated%20carbide" title=" coated carbide"> coated carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology%20%28RSM%29" title=" response surface methodology (RSM)"> response surface methodology (RSM)</a> </p> <a href="https://publications.waset.org/abstracts/75643/modeling-of-austenitic-stainless-steel-during-face-milling-using-response-surface-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75643.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">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Numerical Modeling of a Retaining Wall in Soil Reinforced by Layers of Geogrids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Mellas">M.

The mechanical behavior of reinforced soil by geosynthetic is complex, and requires studies and research to understand the mechanisms of rupture. The behavior of reinforcements in the soil and the behavior of the main elements of the system: reinforcement-wall-soil. The present study is interested in numerical modeling of a retaining wall in soil reinforced by horizontal layers of geogrids. This modeling makes use of the software FLAC3D. This work aims to analyze the effect of the length of the geogrid "L" where the soil massif is supporting a uniformly distributed surcharge "Q", taking into account the fixing elements rather than the layers of geogrids to the wall. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=retaining%20wall" title="retaining wall">retaining wall</a>, <a href="https://publications.waset.org/abstracts/search?q=geogrid" title=" geogrid"> geogrid</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20soil" title=" reinforced soil"> reinforced soil</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=FLAC3D" title=" FLAC3D"> FLAC3D</a> </p> <a href="https://publications.waset.org/abstracts/1335/numerical-modeling-of-a-retaining-wall-in-soil-reinforced-by-layers-of-geogrids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1335.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">484</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Organic Pollution of Waters and Sediments in the Middle and Lower Valley of the Medjerda, Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samia%20Khadhar">Samia Khadhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Anis%20Chekirbene"> Anis Chekirbene</a>, <a href="https://publications.waset.org/abstracts/search?q=Nouha%20Khiari"> Nouha Khiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Mabrouki"> Amira Mabrouki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The persistent organic pollutants (POPs) in aquatic environments are one of the most worrying problems for environmental sustainability and human health because of their carcinogenic and toxic characteristics. Human anthropogenic actions (wastewater discharges, agricultural and industrial activities) without prior treatment are the main cause of this organic pollution. Oued Madjerda is considered the most important river in Tunisia, hence the importance of assessing the level of organic pollution of water and sediments, taking into account the anthropogenic stress exerted on this river. Water and sediment samples were taken from the middle and lower valley of the Medjerda to determine the state of contamination by 7PCBs, priority 15PAHs, and pesticides. The analysis was performed by gas chromatography (GC) and liquid phase coupled to HPLC MS-MS mass spectroscopy. The results showed that for the waters, the total PAH and PCB contents vary respectively from 0.0023 to 7.72 mg/l and from 0.0001 to 0.179 mg/l. In surface sediments 0 to 15 cm, 7PCB levels vary from 1,112 to 110,062 碌g/kg-1. In this study, we tried to determine the concentration of 96 pesticides in surface sediments; analyzes showed the presence of Buprofezin, propamocarb-HCl, hexaconazole, flutriafol, quinalphos, and tebufenpyrad with concentrations varying from 1.06 to 2.388 碌g/kg-1. The pace of the spatial variation confirms the impact of wastewater discharged on the quality of water and sediments despite the perennial aspect of the river. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wadi%20Madjerda" title="Wadi Madjerda">Wadi Madjerda</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20pollution" title=" organic pollution"> organic pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20and%20sediments%20surface" title=" water and sediments surface"> water and sediments surface</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropics%20stress" title=" anthropics stress"> anthropics stress</a> </p> <a href="https://publications.waset.org/abstracts/150228/organic-pollution-of-waters-and-sediments-in-the-middle-and-lower-valley-of-the-medjerda-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150228.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">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Estimation of Natural Pozzolan Reserves in the Volcanic Province of the Moroccan Middle Atlas Using a Geographic Information System in Order to Valorize Them</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brahim%20Balizi">Brahim Balizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayoub%20Aziz"> Ayoub Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelilah%20Bellil"> Abdelilah Bellil</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdellali%20El%20Khadiri"> Abdellali El Khadiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Mabrouki"> Jamal Mabrouki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mio-polio-quaternary volcanism of the Tabular Middle Atlas, which corresponds to prospective levels of exploitable usable raw minerals, is a feature of Morocco's Middle Atlas, especially the Azrou-Timahdite region. Given their importance in national policy in terms of human development by supporting the sociological and economic component, this area has consequently been the focus of various research and prospecting of these levels in order to develop these reserves. The outcome of this labor is a massive amount of data that needs to be managed appropriately because it comes from multiple sources and formats, including side points, contour lines, geology, hydrogeology, hydrology, geological and topographical maps, satellite photos, and more. In this regard, putting in place a Geographic Information System (GIS) is essential to be able to offer a side plan that makes it possible to see the most recent topography of the area being exploited, to compute the volume of exploitation that occurs every day, and to make decisions with the fewest possible restrictions in order to use the reserves for the realization of ecological light mortars The three sites' mining will follow the contour lines in five steps that are six meters high and decline. It is anticipated that each quarry produces about 90,000 m3/year. For a single quarry, this translates to a daily production of about 450 m3 (200 days/year). About 3,540,240 m3 and 10,620,720 m3, respectively, represent the possible net exploitable volume in place for a single quarry and the three exploitable zones. <p
