These risks may occur both during and after the operation phase. The magnitude of these risks depends on the mechanical and physical characteristics of the rock mass, the geometrical dimensions of ore bodies, their spatial arrangement, and the state of the operated area. If security and technology measures are not taken into account for this purpose, the environment will be affected. The main objective of this work is to assess these risks by analytical and numerical methods. The study is based on the geological, hydrogeological and geotechnical rock mass of the open pit quarry of Chouf Amar M'sila. The results obtained have allowed us to obtain an acceptable factor of safety and stability study of the open pit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stability" title="stability">stability</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20sliding" title=" land sliding"> land sliding</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=safety%20factor" title=" safety factor"> safety factor</a>, <a href="https://publications.waset.org/abstracts/search?q=open-pit%20quarry" title=" open-pit quarry"> open-pit quarry</a> </p> <a href="https://publications.waset.org/abstracts/48023/study-of-the-landslide-and-stability-of-open-pit-quarry-case-of-open-pite-quarry-of-chouf-amar-msila-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48023.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">374</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">1675</span> Implementation of a Predictive DTC-SVM of an Induction Motor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chebaani%20Mohamed">Chebaani Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Gplea%20Amar"> Gplea Amar</a>, <a href="https://publications.waset.org/abstracts/search?q=Benchouia%20Mohamed%20Toufik"> Benchouia Mohamed Toufik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Direct torque control is characterized by the merits of fast response, simple structure and strong robustness to the motor parameters variations.

K. Kassem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Neoproterozoic basement rocks of the Ar Rayn terrane have been identified as parts of the Eastern Arabian Shield. It focuses on the petrological and finite strain properties to display the tectonic setting of the Al Amar suture for high deformed volcanic and granitoids rocks. The volcanic rocks are classified into two major series: the eastern side cycle, which includes dacite, rhyodacite, rhyolite, and ignimbrites, and the western side cycle, which includes andesite and pyroclastics. Granitoids rocks also contain monzodiorite, tonalite, granodiorite, and alkali-feldspar granite. To evaluate the proportions of shear contributions in penetratively deformed rocks. Asymmetrical porphyroclast and sigmoidal structural markers along the suture's strike, namely the Al Amar, are expected to reveal strain factors. The Rf/phi and Fry techniques are used to characterize quartz and feldspar porphyroclast, biotite, and hornblende grains in Abt schist, high deformed volcanic rock, and granitoids. The findings exposed that these rocks had experienced shape flattening, finite strain accumulation, and overall volume loss. The magnitude of the strain appears to increase across the nappe contacts with neighboring lithologies. Subhorizontal foliation likely developed in tandem with thrusting and nappe stacking, almost parallel to tectonic contacts. The ductile strain accumulation that occurred during thrusting along the Al Amar suture mostly includes a considerable pure shear component. Progressive thrusting by overlaid transpression and oblique convergence is shown by stacked nappes and diagonal stretching lineations along the thrust axes. The subhorizontal lineation might be the result of the suture's most recent activity. The current study's findings contradict the widely accepted model that links orogen-scale structures in the Arabian Shield to oblique convergence with dominant simple shear deformation. A significant pure shear component/crustal thickening increment should have played a significant role in the evolution of the suture and thus in the Shield's overall deformation history. This foliation was primarily generated by thrusting nappes together, showing that nappe stacking was linked to substantial vertical shortening induced by the active Al Amar suture on a massive scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=petrology" title="petrology">petrology</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20strain%20analysis" title=" finite strain analysis"> finite strain analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=al%20amar%20region" title=" al amar region"> al amar region</a>, <a href="https://publications.waset.org/abstracts/search?q=ar-rayn%20terrane" title=" ar-rayn terrane"> ar-rayn terrane</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabian%20shield" title=" Arabian shield"> Arabian shield</a> </p> <a href="https://publications.waset.org/abstracts/146695/petrology-and-finite-strain-of-the-al-amar-region-northern-ar-rayn-terrane-eastern-arabian-shield-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146695.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">121</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">1671</span> Investigation on Mechanical Properties of a Composite Material of Olive Flour Wood with a Polymer Matrix</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Slim%20Souissi">Slim Souissi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ben%20Amar"> Mohamed Ben Amar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nesrine%20Bouhamed"> Nesrine Bouhamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Marechal"> Pierre Marechal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The bio-composites development from biodegradable materials and natural fibers has a growing interest in the science of composite materials.

X-ray diffraction patterns confirm the formation of the desired compounds of NiAl hydroxide single phase and the crystallite size was found to be about 4.6 nm. The morphology of the prepared samples was investigated using scanning electron microscopy and the layered structure was appeared under the transmission electron microscope. The thermal stability and the function groups of NiAl-LDH were investigated using thermal gravimetric analysis (TGA) and Fourier transform infrared (FTIR) respectively. NiAl-LDH was investigated as a photo-catalyst for the degradation of some toxic dyes such as toluidine blue and bromopyrogallol red. It shows good catalytic efficiency in visible light and even in dark. For the first time NiAl-LDH was used for hydrogen storage application. NiAl-LDH samples were exposed to 20 bar applied hydrogen pressure at room temperature, 100 and -193 oC. NiAl-LDH samples appear to have feasible hydrogen storage capacity. It was capable to adsorb 0.1wt% at room temperature, 0.15 wt% at 100oC and storage capacity reached 0.3 wt% at -193 oC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NiAl-LDH" title="NiAl-LDH">NiAl-LDH</a>, <a href="https://publications.waset.org/abstracts/search?q=preparation" title=" preparation"> preparation</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=photo-catalysis" title=" photo-catalysis"> photo-catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20storage" title=" hydrogen storage"> hydrogen storage</a> </p> <a href="https://publications.waset.org/abstracts/62871/nial-layered-double-hydroxide-preparation-characterization-and-applications-in-photo-catalysis-and-hydrogen-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62871.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">312</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">1666</span> Sudan’s Approach to Knowledge Management in Disaster Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdalla%20Elamein%20Boshara">Mohamed Abdalla Elamein Boshara</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Charles%20Woods"> Peter Charles Woods</a>, <a href="https://publications.waset.org/abstracts/search?q=Nour%20Eldin%20Mohamed%20Elshaiekh"> Nour Eldin Mohamed Elshaiekh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge Management has become very important for Disaster Management response and planning.

In order to achieve this goal, design engineers depend on reliability optimization techniques. This work uses a harmony search algorithm (HS) meta-heuristic optimization method to solve the problem of wind-Solar-Gas power systems design optimization. We consider the case where redundant electrical components are chosen to achieve a desirable level of reliability. The electrical power components of the system are characterized by their cost, capacity and reliability. The reliability is considered in this work as the ability to satisfy the consumer demand which is represented as a piecewise cumulative load curve. This definition of the reliability index is widely used for power systems. The proposed meta-heuristic seeks for the optimal design of series-parallel power systems in which a multiple choice of wind generators, transformers and lines are allowed from a list of product available in the market. Our approach has the advantage to allow electrical power components with different parameters to be allocated in electrical power systems. To allow fast reliability estimation, a universal moment generating function (UMGF) method is applied. A computer program has been developed to implement the UMGF and the HS algorithm. An illustrative example is presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reliability%20optimization" title="reliability optimization">reliability optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=harmony%20search%20optimization%20%28HSA%29" title=" harmony search optimization (HSA)"> harmony search optimization (HSA)</a>, <a href="https://publications.waset.org/abstracts/search?q=universal%20generating%20function%20%28UMGF%29" title=" universal generating function (UMGF)"> universal generating function (UMGF)</a> </p> <a href="https://publications.waset.org/abstracts/11734/hybrid-wind-solar-gas-reliability-optimization-using-harmony-search-under-performance-and-budget-constraints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11734.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">1664</span> Isolation and Molecular Identification of Two Fungal Strains Capable of Degrading hydrocarbon Contaminants on Saudi Arabian Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amr%20A.%20EL%20Hanafy">Amr A.

Analysis of ITS-1, ITS-2 and amplicon pyrosequencing studies of fungal diversity revealed that these strains belong to Penicillium and Aspergillus species. Two strains that proved to be the most efficient in degrading crude oil was Aspergillus niger (54 %) and Penicillium commune (48 %) Subsequent to two weeks of cultivation in BHS medium the degradation rate were recorded by using spectrophotometer and GC-MS. Hence, it is cleared that these fungal strains has the capability of degradation and can be utilized for cleaning the Saudi Arabian environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fungal%20%20strains" title="fungal strains">fungal strains</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20contaminants" title=" hydrocarbon contaminants"> hydrocarbon contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20identification" title=" molecular identification"> molecular identification</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradation" title=" biodegradation"> biodegradation</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a> </p> <a href="https://publications.waset.org/abstracts/36036/isolation-and-molecular-identification-of-two-fungal-strains-capable-of-degrading-hydrocarbon-contaminants-on-saudi-arabian-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36036.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">522</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">1663</span> Experimental Study on Friction Factor of Oscillating Flow Through a Regenerator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sa%C3%AFd%20Kahaleras">Mohamed Saïd Kahaleras</a>, <a href="https://publications.waset.org/abstracts/search?q=Fran%C3%A7ois%20Lanzetta"> François Lanzetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Khan"> Mohamed Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillaume%20Layes"> Guillaume Layes</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Nika"> Philippe Nika</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an experimental work to characterize the dynamic operation of a metal regenerator crossed by dry compressible air alternating flow.

The aim was to detect the effect of papaverine on the proliferation and viability of neural stem cells. Rat neural progenitor cells were isolated from embryos (E14) brains. The dispersed tissues were allowed to settle, then, The supernatant was centrifuged at 1,000 g for 5 min. The pellet was placed in Hank’s solution cultured as free-floating neurospheres Dulbecco’s modified Eagle medium (DMEM) and Hams F12 (3:1) supplemented with B27 (Invitrogen GmBH, Karlsruhe, Germany), 20 ng/mL epidermal growth factor (EGF; Biosource, Karlsruhe, Germany), 20 ng/mL recombinant human fibroblast growth factor (rhFGF; R&D Systems, Wiesbaden-Nordenstadt, Germany), and penicillin and streptomycin (1:100; Invitrogen) at 37°C with 7.5% CO2 . Differentiation was initiated by growth factor withdrawal and plating onto a poly-d-lysine/ laminin matrix. The neurospheres were fed every 2-3 days by replacing 50% of the culture media with fresh media. The culture suspension was transferred to a dish containing 16 wells. The wells were divided as follows: 4 wells received no papaverine (control), 4 wells 1 u, 4 wells 5 u and 4 wells 10 u of papaverine solution. In the next 2 weeks, photography (0,4,5,11days) and viability test were done. The photographs were analysed. Results : papaverine didn't affect proliferation of neurospheres, while it affected viability compared to control , this was dose related. Conclusion: This indicates the harmful effect of papaverine suggesting it to be a candidate neurotoxin causing Parkinsonism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurospheres" title="neurospheres">neurospheres</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20stem%20cells" title=" neural stem cells"> neural stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=papaverine" title=" papaverine"> papaverine</a>, <a href="https://publications.waset.org/abstracts/search?q=Parkinsonism" title=" Parkinsonism"> Parkinsonism</a> </p> <a href="https://publications.waset.org/abstracts/14864/effect-of-papaverine-on-neurospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14864.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">660</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">1652</span> Improved Skin Detection Using Colour Space and Texture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Medjram%20Sofiane">Medjram Sofiane</a>, <a href="https://publications.waset.org/abstracts/search?q=Babahenini%20Mohamed%20Chaouki"> Babahenini Mohamed Chaouki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Benali%20Yamina"> Mohamed Benali Yamina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Skin detection is an important task for computer vision systems.

In the present study, the molecular hybridization tool was adopted to obtain six Schiﬀ bases of isatin and adamantane-1-carbohydrazide (18–23). Then, their anticonvulsant activity was evaluated using a pentylenetetrazole- (PTZ-) induced seizure model using phenobarbitone as a positive control. Our ﬁndings showed that compounds 18–23 provided signiﬁcant protection against PTZ-induced seizure, and maximum activities were associated with compound 23. Moreover, all investigated compounds increased the latency of induced convulsion and reduced the duration of epilepsy, with compound 23 being the best. Interestingly, most of the synthesized molecules showed a reduction in neurological symptoms and severity of the seizure. Molecular docking studies suggest GABA-A receptor as a potential target, and in silico ADME screening revealed that the pharmaceutical properties of compound 23 are within the speciﬁed limit. Thus, compound 23 was identified as a promising candidate that warrants further drug discovery processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isatin%20and%20adamantane" title="isatin and adamantane">isatin and adamantane</a>, <a href="https://publications.waset.org/abstracts/search?q=anticonvulsant%20activity" title=" anticonvulsant activity"> anticonvulsant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=PTZ-induced%20seizure" title=" PTZ-induced seizure"> PTZ-induced seizure</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a> </p> <a href="https://publications.waset.org/abstracts/145055/schiff-bases-of-isatin-and-admantane-1-carbohydrazide-synthesis-characterization-and-anticonvulsant-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145055.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">207</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">1647</span> Compact Ultra-Wideband Printed Monopole Antenna with Inverted L-Shaped Slots for Data Communication and RF Energy Harvesting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Adel%20Sennouni">Mohamed Adel Sennouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Zbitou"> Jamal Zbitou</a>, <a href="https://publications.waset.org/abstracts/search?q=Benaissa%20Abboud"> Benaissa Abboud</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelwahed%20Tribak"> Abdelwahed Tribak</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Bennis"> Hamid Bennis</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Latrach"> Mohamed Latrach </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A compact UWB planar antenna fed with a microstrip-line is proposed. The new design is composed of a rectangular patch with symmetric L-shaped slots and fed by 50 Ω microstrip transmission line and a reduced ground-plane which have a periodic slots with an overall size of 47 mm x 20 mm. It is intended to be used in wireless applications that cover the ultra-wideband (UWB) frequency band.
