On regional characteristics, bibliography and available data on artificial recharge, 13 constraints and 5 factors were hierarchically structured for the adequacy of an artificial recharge. The factors are subdivided into two main groups: environmental factors and economic factors. The adopted methodology allows a preliminary assessment of a recharge site, the weighted linear combination (WLC) and the analytical hierarchy process (AHP) in a GIS. The standardization of the criteria is carried out by the application of the different membership functions. The form and control points of the latter are defined by the consultation of the experts. The weighting of the selected criteria is allocated according to relative importance using the AHP methodology. The weighted linear combination (WLC) integrates the different criteria and factors to delineate the most suitable areas for artificial recharge site selection by treated wastewater. The results of this study showed three potential candidate sites that appear when environmental factors are more important than economic factors. These sites are ranked in descending order using the ELECTRE III method. Nevertheless, decision making for the selection of an artificial recharge site will depend on the decision makers in force. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20recharge%20site" title="artificial recharge site">artificial recharge site</a>, <a href="https://publications.waset.org/abstracts/search?q=treated%20wastewater" title=" treated wastewater"> treated wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchy%20process" title=" analytical hierarchy process"> analytical hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=ELECTRE%20III" title=" ELECTRE III "> ELECTRE III </a> </p> <a href="https://publications.waset.org/abstracts/105235/integrating-gis-and-analytical-hierarchy-process-multicriteria-decision-analysis-for-identification-of-suitable-areas-for-artificial-recharge-with-reclaimed-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105235.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">6</span> Bio-Desalination and Bioremediation of Agroindustrial Wastewaters Using Yarrowia Lipolytica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Selma%20Hamimed">Selma Hamimed</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelwaheb%20Chatti"> Abdelwaheb Chatti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current study deals with the biological treatment of saline wastewaters generated by various agro-food industries using Yarrowia lipolytica. The ability of this yeast was studied on the mixture of olive mill wastewater and tuna wash processing wastewater. Results showed that the high proportion of olive mill wastewater in the mixture about (75:25) is the suitable one for the highest Y. lipolytica biomass production, reaching 11.3 g L⁻¹ after seven days. In addition, results showed significant removal of chemical oxygen demand (COD) and phosphorous of 97.49 % and 98.90 %, respectively. On the other hand, Y. lipolytica was found to be effective to desalinate all mixtures reaching a removal of 92.21 %. Moreover, the analytical results using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) confirmed the biosorption of NaCl on the surface of the yeast as nanocrystals form with a size of 47.3 nm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanocrystallization%20of%20NaCl" title="nanocrystallization of NaCl">nanocrystallization of NaCl</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title=" wastewater treatment"> wastewater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=yarrowia%20lipolytica" title=" yarrowia lipolytica"> yarrowia lipolytica</a> </p> <a href="https://publications.waset.org/abstracts/139746/bio-desalination-and-bioremediation-of-agroindustrial-wastewaters-using-yarrowia-lipolytica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139746.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">187</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">5</span> Experimental Characterization of Anisotropic Mechanical Properties of Textile Woven Fabric</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rym%20Zouari">Rym Zouari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Ben%20Amar"> Sami Ben Amar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelwaheb%20Dogui"> Abdelwaheb Dogui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an experimental characterization of the anisotropic mechanical behavior of 4 textile woven fabrics with different weaves (Twill 3, Plain, Twill4 and Satin 4) by off-axis tensile testing.

Analysis of experimental results is done through global (Effort/Elongation curves) and local scales. Global anisotropy was studied from the Effort/Elongation curves: shape, breaking load (Frup), tensile elongation (EMT), tensile energy (WT) and linearity index (LT). Local anisotropy was studied from the measurement of strain tensor components in the central area of the specimen as a function of testing orientation and effort: longitudinal strain ɛL, transverse strain ɛT and shearing ɛLT.

Also, an adaptive robust Radial Basis Function (RBF) neural network is used to estimate the environment torque. The parameters of the environment torque are then sent from the slave site to the master site as a non-power signal to avoid passivity problems. Moreover, a nonlinear function is applied to each controller term as a smooth saturation function, providing a bounded control signal and preserving the system’s actuators. Lastly, the Lyapunov approach demonstrates the global stability of the controlled system, and numerical experiment results further confirm the validity of the presented strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teleoperation%20manipulators%20system" title="teleoperation manipulators system">teleoperation manipulators system</a>, <a href="https://publications.waset.org/abstracts/search?q=time-varying%20delay" title=" time-varying delay"> time-varying delay</a>, <a href="https://publications.waset.org/abstracts/search?q=actuator%20saturation" title=" actuator saturation"> actuator saturation</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20robust%20rbf%20neural%20network%20approximation" title=" adaptive robust rbf neural network approximation"> adaptive robust rbf neural network approximation</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainties" title=" uncertainties"> uncertainties</a> </p> <a href="https://publications.waset.org/abstracts/166930/rbf-neural-network-based-adaptive-robust-control-for-bounded-positionforce-control-of-bilateral-teleoperation-arms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166930.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">75</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> Biocontrol of Fusarium Crown and Root Rot and Enhancement of Tomato Solanum lycopersicum L.

Leaf extract used at 30% w/v was the most effective in reducing leaf and root damage index by 92.3% and the extent of vascular discoloration by 97.56% compared to Fusarium oxyxporum f. sp radicis lycopersici -inoculated and untreated control. A significant promotion of growth parameters (root length, shoot height, root and shoot biomass and stem diameter) was recorded on tomato cv. Rio Grande seedlings by 40.3-94.1% as compared to FORL inoculated control and by 9.6-88.8% over pathogen-free control. All S. linnaeanum aqueous extracts tested significantly stimulated the germination by 10.2 to 80.1% relative to the untreated control. FORL mycelial growth, assessed using the poisoned food technique, varied depending on plant organs, extracts, and concentrations used. Butanolic extracts were the most active, leading to 60.81% decrease in FORL mycelial growth. HPLC analysis of butanolic extract revealed the presence of thirteen phenolic compounds. Thus, S. linnaeanum can be explored as a potential natural source of antifungal and biofertilizing compounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antifungal%20activity" title="antifungal activity">antifungal activity</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC-MS%20analysis" title=" HPLC-MS analysis"> HPLC-MS analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Fusarium%20oxysporum%20f.%20sp.%20radicis-lycopersici" title=" Fusarium oxysporum f. sp. radicis-lycopersici"> Fusarium oxysporum f. sp. radicis-lycopersici</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato%20growth" title=" tomato growth"> tomato growth</a> </p> <a href="https://publications.waset.org/abstracts/90546/biocontrol-of-fusarium-crown-and-root-rot-and-enhancement-of-tomato-solanum-lycopersicum-l-growth-using-solanum-linnaeanum-l-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90546.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">160</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> Endophytic Fungi Recovered from Lycium arabicum as an Eco-Friendly Alternative for Fusarium Crown and Root Rot Disease Control and Tomato Growth Enhancement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahlem%20Nefzi">Ahlem Nefzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rania%20Aydi%20Ben%20Abdallah"> Rania Aydi Ben Abdallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayfa%20Jabnoun-Khiareddine"> Hayfa Jabnoun-Khiareddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Nawaim"> Ammar Nawaim</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabiaa%20Haouala"> Rabiaa Haouala</a>, <a href="https://publications.waset.org/abstracts/search?q=Mejda%20Daami-Remadi"> Mejda Daami-Remadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seven endophytic fungi were isolated from the wild Solanaceous species Lycium arabicum growing in the Tunisian Centre-East and were assessed for their ability to suppress Fusarium Crown and Root Rot disease caused by Fusarium oxysporum f. sp. radicis lycopersici (FORL) and to enhance plant growth. Fungal isolates were shown able to colonize tomato cv. Rio Grande roots, crowns, and stems. A significant promotion in all studied growth parameters (root length, shoot height, and roots and shoots fresh weight) was recorded in tomato plants treated with fungal conidial suspensions or their cell-free culture filtrates compared to FORL-inoculated or pathogen-free controls. I15 and I18 isolates were shown to be the most effective leading to 85.7-87.5 and 93.6-98.4% decrease in leaf and root damage index and the vascular discoloration extent, respectively, over FORL-inoculated and untreated control. These two bioactive and growth-promoting isolates (I15 and I18) were morphologically characterized and identified using rDNA sequencing gene as being Alternaria alternata (MF693801) and Fusarium fujikuroi (MF693802). These fungi significantly suppressed FORL mycelial growth and showed chitinolytic, proteolytic and amylase activities whereas only F. fujikuroi displayed a lipolytic activity.

Its management is very difficult due to the long survival of its resting structures and to the luck of genetic resistance. In this work, we explored the wild Solanaceae species Withania somnifera, growing in the Tunisian Centre-East, as a potential source of biocontrol agents effective in FCRR suppression and tomato growth promotion. Seven fungal isolates were shown able to colonize tomato roots, crowns, and stems. Used as conidial suspensions or cell-free culture filtrates, all tested fungal treatments significantly enhanced tomato growth parameters by 21.5-90.3% over FORL-free control and by 27.6-93.5% over pathogen-inoculated control. All treatments significantly decreased the leaf and root damage index by 28.5-92.8 and the vascular browning extent 9.7-86.4% over FORL-inoculated and untreated control. The highest disease suppression ability (decrease by 86.4-92.8% in FCRR severity) over pathogen-inoculated control and by 81.3-88.8 over hymexazol-treated control) was expressed by I6 based treatments. This endophytic fungus was morphologically characterized and identified using rDNA sequencing gene as Fusarium sp. I6 (MG835371). This fungus was shown able to reduce FORL radial growth by 58.5–83.2% using its conidial suspension or cell-free culture filtrate. Fusarium sp. I6 showed chitinolytic, proteolytic and amylase activities. The current study clearly demonstrated that Fusarium sp. (I6) is a promising biocontrol candidate for suppressing FCRR severity and promoting tomato growth. Further investigations are required for elucidating its mechanism of action involved in disease suppression and plant growth promotion. <p class="card-text"><strong>Keywords:</strong> <a
