Various techniques have been used, includingdegradation, filtration, advancedoxidationprocesses, ion exchange, membrane processes, and adsorption. The latter is one of the mostsuitablemethods, usinghighly efficient materials. In this study, NaX zeolite was modified with Cu or Ni at various rates. Following ion exchange, the samples were characterized by XRD, BET and SEM/EDX. After characterization, the exchanged zeolites were used for adsorption of various pollutants as CO2. Different thermodynamic parameters were studied such as Qst. XRD results show that the most intense peaks characteristic of 13X persist after the exchange reaction for all samples. The SEM images of our samples have uniform and regular crystal shapes. The results show that ion exhange with Cu or Ni affect the textural properties of X zeolites and prove that the exchange zeolites can be used as an adsorbent for depollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=X%20zeolites%20%28NaX%29" title="X zeolites (NaX)">X zeolites (NaX)</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange" title=" ion exchange"> ion exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a> </p> <a href="https://publications.waset.org/abstracts/174447/investigation-of-modified-microporous-materials-for-environmental-depollution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174447.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">88</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">34</span> Improved Photo-Active Layer Properties for Efficient Organic Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chahrazed%20Bendenia">Chahrazed Bendenia</a>, <a href="https://publications.waset.org/abstracts/search?q=Souhila%20Bendenia"> Souhila Bendenia</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20Moulebhar"> Samia Moulebhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20Merad-Dib"> Hanaa Merad-Dib</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Merabet"> Sarra Merabet</a>, <a href="https://publications.waset.org/abstracts/search?q=Sid%20Ahmed%20Khantar"> Sid Ahmed Khantar</a>, <a href="https://publications.waset.org/abstracts/search?q=Baghdad%20Hadri"> Baghdad Hadri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, organic solar cells (OSCs) have become the fundamental concern of researchers thanks to their advantages in terms of flexibility, manufacturing processes and low cost. The performance of these devices is influenced by various factors, such as the layers introduced in the stacking of the solar cell realized. In our work, the modeling of a reverse OSC under AM1.5G illumination will be determined. The photo-active polymer/fullerene layer will be analyzed from the polymer variation of this layer using the SCAPS simulator to extract the J-V characteristics: open circuit voltage (Voc), short circuit current (Jsc), filling factor (FF) and power conversion efficiency (η).

Currently, distribution companies rely heavily on contextual variables (music, smells, colors, sound, design ...) in order to push customers towards purchase and consumption. As such, a crucial way for commercial brands to increase sales is to stimulate impulse buying. For this reason, this study aims at identifying the factors that initiate and encourage impulse buying, as well as the levers that help distributors highlight effective marketing techniques in order to encourage consumers to make impulse purchase. Thus, we try to show, upon a field survey of 590 buyers, the impact of situational elements of both the store and the product on achieving impulse buying. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algerian%20shoppers" title="Algerian shoppers">Algerian shoppers</a>, <a href="https://publications.waset.org/abstracts/search?q=impulse%20buying" title=" impulse buying"> impulse buying</a>, <a href="https://publications.waset.org/abstracts/search?q=shopping%20environment" title=" shopping environment"> shopping environment</a>, <a href="https://publications.waset.org/abstracts/search?q=situational%20variables" title=" situational variables"> situational variables</a>, <a href="https://publications.waset.org/abstracts/search?q=product" title=" product"> product</a> </p> <a href="https://publications.waset.org/abstracts/27654/the-study-of-the-determinants-of-impulse-buying-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27654.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">351</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">31</span> Association Rules Mining and NOSQL Oriented Document in Big Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Senhadji">Sarra Senhadji</a>, <a href="https://publications.waset.org/abstracts/search?q=Imene%20Benzeguimi"> Imene Benzeguimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohra%20Yagoub"> Zohra Yagoub</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Big Data represents the recent technology of manipulating voluminous and unstructured data sets over multiple sources.

During the development of the approach, we focused on the graphical aspect of the application in terms of interfaces while opting for the Model View Presenter pattern that is designed for graphics interfaces. The paper describes the process followed to define the approach, the supporting tool and presents the results from a case study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metamodel" title="metamodel">metamodel</a>, <a href="https://publications.waset.org/abstracts/search?q=model-driven%20engineering" title=" model-driven engineering"> model-driven engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=MVP" title=" MVP"> MVP</a>, <a href="https://publications.waset.org/abstracts/search?q=rich%20internet%20application" title=" rich internet application"> rich internet application</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation" title=" transformation"> transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20interface" title=" user interface"> user interface</a> </p> <a href="https://publications.waset.org/abstracts/36531/a-model-driven-approach-of-user-interface-for-mvp-rich-internet-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36531.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">353</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">27</span> Isolation and Characterization of Salt-Tolerance of Rhizobia under the Effects of Salinity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Sobti">Sarra Sobti</a>, <a href="https://publications.waset.org/abstracts/search?q=Baelhadj%20Hamdi-A%C3%AFssa"> Baelhadj Hamdi-Aïssa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The bacteria of the soil, usually called rhizobium, have a considerable importance in agriculture because of their capacity to fix the atmospheric nitrogen in symbiosis with the plants of the family of legumes. The present work was to study the effect of the salinity on growth and nodulation of alfalfa-rhizobia symbiosis at different agricultural experimental sites in Ouargla. The experiment was conducted in 3 steps. The first one was the isolation and characterization of the Rhizobia; next, the evolution of the isolates tolerance to salinity at three levels of NaCl (6, 8,12 and 16 g/L); and the last step was the evolution of the tolerance on symbiotic characteristics. The results showed that the phenotypic characterizations behave practically as Rhizobia spp, and the effects of salinity affect the symbiotic process. The tolerance to high levels of salinity and the survival and persistence in severe and harsh desert conditions make these rhizobia highly valuable inoculums to improve productivity of the leguminous plants cultivated under extreme environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rhizobia" title="rhizobia">rhizobia</a>, <a href="https://publications.waset.org/abstracts/search?q=symbiosis" title=" symbiosis"> symbiosis</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=tolerance" title=" tolerance"> tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=nodulation" title=" nodulation"> nodulation</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=Medicago%20sativa%20L." title=" Medicago sativa L."> Medicago sativa L.</a> </p> <a href="https://publications.waset.org/abstracts/8701/isolation-and-characterization-of-salt-tolerance-of-rhizobia-under-the-effects-of-salinity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8701.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">26</span> Maximum Power Point Tracking Based on Estimated Power for PV Energy Conversion System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zainab%20Almukhtar">Zainab Almukhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Merabet"> Adel Merabet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a method for maximum power point tracking of a photovoltaic energy conversion system is presented. This method is based on using the difference between the power from the solar panel and an estimated power value to control the DC-DC converter of the photovoltaic system. The difference is continuously compared with a preset error permitted value. If the power difference is more than the error, the estimated power is multiplied by a factor and the operation is repeated until the difference is less or equal to the threshold error. The difference in power will be used to trigger a DC-DC boost converter in order to raise the voltage to where the maximum power point is achieved. The proposed method was experimentally verified through a PV energy conversion system driven by the OPAL-RT real time controller. The method was tested on varying radiation conditions and load requirements, and the Photovoltaic Panel was operated at its maximum power in different conditions of irradiation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control%20system" title="control system">control system</a>, <a href="https://publications.waset.org/abstracts/search?q=error" title=" error"> error</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20panel" title=" solar panel"> solar panel</a>, <a href="https://publications.waset.org/abstracts/search?q=MPPT%20tracking" title=" MPPT tracking"> MPPT tracking</a> </p> <a href="https://publications.waset.org/abstracts/41868/maximum-power-point-tracking-based-on-estimated-power-for-pv-energy-conversion-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41868.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">283</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">25</span> Power Management Strategy for Solar-Wind-Diesel Stand-Alone Hybrid Energy System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Aminul%20Islam">Md.

The most common the contaminants generated by industrial urban emissions and agricultural practices are trace metals). Remediation of trace metals which pollute soils can be carried out using physico-chemical processes. Nevertheless, these techniques damage the soil’s biological activity and require expensive equipment. Phytoremediation is a relatively low-cost technology based on the use of selected plants to remove, degrades or contains pollutants. The potential of kenaf for phytoremediation on Cd-contaminated soil was investigated. kenaf plants have been grown in pots containing different concentrations of cadmium. The observations made were for biomass production and cadmium content in different organs determinate by atomic emission spectrometry. Cadmium transfer from a contaminated soil to plants and into plant tissues are discussed in terms of the Bioconcentration Factor (BCF) and the Transfer Factor (TF). Results showed that Cd was found in kenaf plants at different levels. Tolerance and accumulation potential and biomass productivity indicated that kenaf could be used in phytoremediation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kenaf" title="kenaf">kenaf</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium" title=" cadmium"> cadmium</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoremediation" title=" phytoremediation"> phytoremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=contaminated%20soil" title=" contaminated soil"> contaminated soil</a> </p> <a href="https://publications.waset.org/abstracts/17031/phytoremediation-potential-of-hibiscus-cannabinus-l-grown-on-different-soil-cadmium-concentration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17031.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">525</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">22</span> Multiobjective Optimization of Wastwater Treatment by Electrochemical Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malek%20Bendjaballah">Malek Bendjaballah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hacina%20Saidi"> Hacina Saidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Hamidoud"> Sarra Hamidoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to model and optimize the performance of a new electrocoagulation (E.C) process for the treatment of wastewater as well as the energy consumption in order to extrapolate it to the industrial scale. Through judicious application of an experimental design (DOE), it has been possible to evaluate the individual effects and interactions that have a significant influence on both objective functions (maximizing efficiency and minimizing energy consumption) by using aluminum electrodes as sacrificial anode. Preliminary experiments have shown that the pH of the medium, the applied potential and the treatment time with E.C are the main parameters. A factorial design 33 has been adopted to model performance and energy consumption. Under optimal conditions, the pollution reduction efficiency is 93%, combined with a minimum energy consumption of 2.60.10-3 kWh / mg-COD. The potential or current applied and the processing time and their interaction were the most influential parameters in the mathematical models obtained.

We extend our evaluations to Large Language Models (LLMs) as post hoc explainers for tweet geolocation.

The first one is extensive (EP), which is carried out in a treatment chain of two steps, allowing the adsorption of the pollutant by a naturally activated carbon from the grapes. This operation is followed by a photocatalytic degradation of the residual phenol in the presence of TiO₂. The second process is intensive (IP) and is realized in one step in the presence of a hybrid photocatalytic nanomaterial prepared from naturally activated carbon and TiO₂. The evaluation of the two processes, EP and IP, is based on the analytical monitoring of the initial and final parameters of the water to be treated, i.e., the phenol concentration by liquid phase chromatography (HPLC) and total organic carbon (TOC). For both processes, the sampling was carried out every 10 min for 120 min of treatment time to measure the phenol concentrations. The elimination and degradation rates in the case of the intensive process are better than the extensive process. In both processes, the catechol molecule was detected as an under product of degradation. In the IP case, this intermediate phenol was totally eliminated, and only traces of catechol persisted in the water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title="photocatalysis">photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid" title=" hybrid"> hybrid</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title=" activated carbon"> activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=phenol" title=" phenol"> phenol</a> </p> <a href="https://publications.waset.org/abstracts/185757/phenol-removal-from-water-in-the-presence-of-nano-tio2-and-a-natural-activated-carbon-intensive-and-extensive-processes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185757.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">53</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">18</span> Chemical Composition and Antibacterial Activity of Ceratonia siliqua L.

They offer access to a large panel of enantiopure building blocks, such as secondary benzylic alcohols, commonly used as synthetic intermediates in pharmaceutical and agrochemical industries. Due to the stability of lipases in both water and organic solvents poor in water, they are able to catalyze both transesterifications of arylalkylcarbinols and hydrolysis of their corresponding acetates. The use of enzymatic hydrolysis in aqueous media still limited. In this presentation, we expose a practical methodology for the preparation of optically enriched acetates using a Candida antarctica lipase B-catalyzed hydrolysis in non-aqueous media in the presence of alkaline carbonate salts. The influence of several parameters which can intervene on the enzymatic efficiency such as the impact of the introduction of the carbonates salts, its amount and the nature of the alkaline earth metal are discussed. The obtained results show that the use of sodium carbonate with CAL-B enhances drastically both reactivity and selectivity of this immobilized lipase. In all cases, the resulting alcohols and remaining acetates are obtained in high ee values (up to > 99 %), and the selectivities reach (E > 500). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkaline-hydrolysis" title="alkaline-hydrolysis">alkaline-hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymatic%20kinetic%20resolution" title=" enzymatic kinetic resolution"> enzymatic kinetic resolution</a>, <a href="https://publications.waset.org/abstracts/search?q=lipases" title=" lipases"> lipases</a>, <a href="https://publications.waset.org/abstracts/search?q=arylalkylcarbinol" title=" arylalkylcarbinol"> arylalkylcarbinol</a>, <a href="https://publications.waset.org/abstracts/search?q=non-aqueous%20media" title=" non-aqueous media"> non-aqueous media</a> </p> <a href="https://publications.waset.org/abstracts/75965/candida-antarctica-lipase-b-catalyzed-alkaline-hydrolysis-of-some-aryl-alkyl-acetate-in-non-aqueous-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75965.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">162</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">16</span> Membrane Bioreactor versus Activated Sludge Process for Aerobic Wastewater Treatment and Recycling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Kitanou">Sarra Kitanou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Membrane bioreactor (MBR) systems are one of the most widely used wastewater treatment processes for various municipal and industrial waste streams. It is based on complex interactions between biological processes, filtration process and rheological properties of the liquid to be treated. Its complexity makes understanding system operation and optimization more difficult, and traditional methods based on experimental analysis are costly and time consuming. The present study was based on an external membrane bioreactor pilot scale with ceramic membranes compared to conventional activated sludge process (ASP) plant. Both systems received their influent from a domestic wastewater. The membrane bioreactor (MBR) produced an effluent with much better quality than ASP in terms of total suspended solids (TSS), organic matter such as biological oxygen demand (BOD) and chemical oxygen demand (COD), total Phosphorus and total Nitrogen. Other effluent quality parameters also indicate substantial differences between ASP and MBR. This study leads to conclude that in the case domestic wastewater, MBR treatment has excellent effluent quality. Hence, the replacement of the ASP by the MBRs may be justified on the basis of their improved removal of solids, nutrients, and micropollutants. Furthermore, in terms of reuse the great quality of the treated water allows it to be reused for irrigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerobic%20wastewater%20treatment" title="aerobic wastewater treatment">aerobic wastewater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20activated%20sludge%20process" title=" conventional activated sludge process"> conventional activated sludge process</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20bioreactor" title=" membrane bioreactor"> membrane bioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=reuse%20for%20irrigation" title=" reuse for irrigation"> reuse for irrigation</a> </p> <a href="https://publications.waset.org/abstracts/167997/membrane-bioreactor-versus-activated-sludge-process-for-aerobic-wastewater-treatment-and-recycling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167997.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">78</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">15</span> Impacts on the Modification of a Two-Blade Mobile on the Agitation of Newtonian Fluids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abderrahim%20Sidi%20Mohammed%20Nekrouf">Abderrahim Sidi Mohammed Nekrouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Youcefi"> Sarra Youcefi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fluid mixing plays a crucial role in numerous industries as it has a significant impact on the final product quality and performance. In certain cases, the circulation of viscous fluids presents challenges, leading to the formation of stagnant zones. To overcome this issue, stirring devices are employed for fluid mixing. This study focuses on a numerical analysis aimed at understanding the behavior of Newtonian fluids when agitated by a two-blade agitator in a cylindrical vessel. We investigate the influence of the agitator shape on fluid motion. Bi-blade agitators of this type are commonly used in the food, cosmetic, and chemical industries to agitate both viscous and non-viscous liquids. Numerical simulations were conducted using Computational Fluid Dynamics (CFD) software to obtain velocity profiles, streamlines, velocity contours, and the associated power number. The obtained results were compared with experimental data available in the literature, validating the accuracy of our numerical approach. The results clearly demonstrate that modifying the agitator shape has a significant impact on fluid motion. This modification generates an axial flow that enhances the efficiency of the fluid flow. The various velocity results convincingly reveal that the fluid is more uniformly agitated with this modification, resulting in improved circulation and a substantial reduction in stagnant zones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Newtonian%20fluids" title="Newtonian fluids">Newtonian fluids</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=two%20blade." title=" two blade."> two blade.</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a> </p> <a href="https://publications.waset.org/abstracts/169839/impacts-on-the-modification-of-a-two-blade-mobile-on-the-agitation-of-newtonian-fluids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169839.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">78</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">14</span> H₆P₂W₁₈O₆₂.14H₂O Catalyzed Synthesis of α-Aminophosphonates from Amino Acids Esters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Boughaba">Sarra Boughaba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> α-aminophosphonates have found a wide range of applications in organic and medicinal chemistry; they are considered as pharmacological agents, anti-inflammatory antitumor agents, and antibiotics.

Their Spatio-temporal distribution is never homogeneous and depends mainly on the hydrodynamic characteristics of the environment and the size and location of the wastes. As part of optimizing collect of marine plastic wastes, it is important to measure and monitor their evolution over time. For this, many research studies have been dedicated to describing the wastes behavior in order to identify their accumulation in oceans areas. Several models are therefore developed to understand the mechanisms that allow the accumulation and the displacements of marine litter. These models are able to accurately simulate the drift of wastes to study their behavior and stranding. However, these works aim to study the wastes behavior over a long period of time and not at the time of waste collection. This work investigates the transport of floating marine litter (FML) to provide basic information that can help in optimizing wastes collection by proposing a model for predicting their behavior during collection. The proposed study is based on a Lagrangian modeling approach that uses the main factors influencing the dynamics of the waste. The performance of the proposed method was assessed on real data collected from the Copernicus Marine Environment Monitoring Service (CMEMS). Evaluation results in the Java Sea (Indonesia) prove that the proposed model can effectively predict the position and the velocity of marine wastes during collection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=floating%20marine%20litter" title="floating marine litter">floating marine litter</a>, <a href="https://publications.waset.org/abstracts/search?q=lagrangian%20transport" title=" lagrangian transport"> lagrangian transport</a>, <a href="https://publications.waset.org/abstracts/search?q=particle-tracking%20model" title=" particle-tracking model"> particle-tracking model</a>, <a href="https://publications.waset.org/abstracts/search?q=wastes%20drift" title=" wastes drift"> wastes drift</a> </p> <a href="https://publications.waset.org/abstracts/139690/lagrangian-approach-for-modeling-marine-litter-transport" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139690.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">191</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">12</span> The Palm Oil in Food Products: Frequency of Consumption and Composition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamilia%20Ounaissa">Kamilia Ounaissa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Fennira"> Sarra Fennira</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Ben%20Brahim"> Asma Ben Brahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Omri"> Marwa Omri</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelmajid%20Abid"> Abdelmajid Abid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The palm oil is the vegetable oil the most used by the food-processing industry in the world. It is chosen for its economic and technologic advantages. However, this oil arouses the debate because of its high content in saturated fatty acids, which are fats promoting atherosclerosis. Purposes of the work: To study the frequency and the rate of consumption of industrial products containing some palm oil and specify the rate of this oil in certain consummated products. Methodology: We proceeded to a consumer survey using a questionnaire collecting a list of food containing the palm oil, sold on the Tunisian market. We then analyzed the most consumed food to specify their fat content by “Soxhelt’s” method. Finally, we studied the composition in various fatty acids of the extracted fat using the chromatography in the gas phase (CPG) Results: Our results show that investigated individuals having a normal weight have a more important and more frequent consumption of products rich in palm oil than overweight subjects. The most consumed foods are biscuits, cakes, wafers, chocolates, chips, cereal, creams to be spread and canned pilchard. The content in palm oil of these products varies from 10 % to 31 %. The analysis by CPG showed an important content in saturated fatty acid, in particular in palmitic acid, ranging from 40 % to 63 % of the fat of these products. Conclusion: Our study shows a high frequency of consumption of food products, the analysis of which proved a high content in palm oil. Theses facts justifies the necessity of a regulation of the use of palm oil in food products and the application of a label detailing the type and fat rates used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm%20oil" title="palm oil">palm oil</a>, <a href="https://publications.waset.org/abstracts/search?q=palmitic%20acid" title=" palmitic acid"> palmitic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20industry" title=" food industry"> food industry</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=atherosclerosis" title=" atherosclerosis"> atherosclerosis</a> </p> <a href="https://publications.waset.org/abstracts/26258/the-palm-oil-in-food-products-frequency-of-consumption-and-composition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26258.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">544</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">11</span> H₆P₂W₁₈O₆₂.14H₂O Catalyzed Synthesis and X-Ray Study of α-Aminophosphonates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Boughaba">Sarra Boughaba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The α-aminophosphonates have received considerable attention in organic and medicinal chemistry because of their structural resemblance with α-amino acids.

The aim of this work is to eliminate such drawbacks by combining AC and titanium dioxide (TiO₂) in a photocatalytically Regenerative Activated Carbon. Anatase titania was deposited on powder-activated carbon made from grape seeds by the impregnation method, and then the composite photocatalyst was employed for the removal of reactive black 5, which is an anionic azo dye, from water. The AGS/TiO₂ was characterized by BET, MEB, RDX and optical absorption spectroscopy. The BET surface area and the pore structure of composite photocatalysts (AGS/TiO₂) and activated grape seeds (AGS) were evaluated from nitrogen adsorption data at 77 K in relation to process conditions. Our results indicate that the photocatalytic activity of AGS/TiO₂ was much higher than single-phase titania. The adsorption equilibrium of reactive black 5 from aqueous solutions on the examined materials was investigated. Langmuir, Freundlich, and Redlich–Petersen models were fitted to experimental equilibrium data, and their goodness of fit is compared. The degradation kinetics fitted well to the Langmuir-Hinselwood pseudo first order rate low. The photocatalytic activity of AGS/TiO₂ was much higher than virgin TiO₂. Chemical oxygen demand (COD) removal was measured at regular intervals to quantify the mineralization of the dye. Above 96% mineralization was observed. These results suggest that UV-irradiated TiO₂ immobilized on activated carbon may be considered an adequate process for the treatment of diluted colored textile wastewater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=pollutant" title=" pollutant"> pollutant</a>, <a href="https://publications.waset.org/abstracts/search?q=catalysis" title=" catalysis"> catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO%E2%82%82" title=" TiO₂"> TiO₂</a> </p> <a href="https://publications.waset.org/abstracts/185955/removal-capacity-of-activated-carbon-ac-by-combining-ac-and-titanium-dioxide-tio2-in-a-photocatalytically-regenerative-activated-carbon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185955.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">50</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">9</span> Unlocking the Potential of Neglected Cereal Resources Waste: Exploring Functional Properties of Algerian Pearl Millet Starch via Wet Milling and Ultrasound Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Bouhallel">Sarra Bouhallel</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Legbedj"> Sara Legbedj</a>, <a href="https://publications.waset.org/abstracts/search?q=Rima%20Messaoud"> Rima Messaoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Sofia%20Saffarbatti"> Sofia Saffarbatti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the context of global waste management and sustainable resource utilization, millets emerge as a vital yet underutilized cereal resource. Despite their exceptional nutritional profile and resilience to harsh environmental conditions, their potential remains largely untapped. This study aims to contribute to the valorization of seven Algerian pearl millet landraces (Pennisetum glaucum (L.) R. Br) from the southern region by focusing on the characterization of their starches. Utilizing both conventional wet milling, incorporating sodium azide as a microbial growth inhibitor, and a novel green technology—Ultrasound-assisted isolation, we explore avenues for enhancing the functional properties of these starches. Analysis of key functional properties such as swelling power and water solubility index reveals significant enhancements, particularly during heat treatment near the gelatinization temperature [70 - 80 °C]. Furthermore, our investigation into the influence of pre-treatment methods on isolated starches highlights the potential of Ultrasound-assisted isolation in reducing absorbency and water solubility compared to conventional methods. Through rigorous data analysis using SPSS software (Version 23), we ascertain the efficiency of Ultrasound-assisted isolation, underscoring its promising role in the valorization of pearl millet waste. This research not only sheds light on the functional properties of pearl millet starch but also underscores the imperative of sustainable waste management in harnessing the full potential of underutilized cereal resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isolation" title="isolation">isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility" title=" solubility"> solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=starch" title=" starch"> starch</a>, <a href="https://publications.waset.org/abstracts/search?q=swelling" title=" swelling"> swelling</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/185147/unlocking-the-potential-of-neglected-cereal-resources-waste-exploring-functional-properties-of-algerian-pearl-millet-starch-via-wet-milling-and-ultrasound-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185147.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">65</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">8</span> Emotional Intelligence Training: Helping Non-Native Pre-Service EFL Teachers to Overcome Speaking Anxiety: The Case of Pre-Service Teachers of English, Algeria </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khiari%20Nor%20El%20Houda">Khiari Nor El Houda</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiouani%20Amira%20Sarra"> Hiouani Amira Sarra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many EFL students with high capacities are hidden because they suffer from speaking anxiety (SA). Most of them find public speaking much demanding. They feel unable to communicate, they fear to make mistakes and they fear negative evaluation or being called on. With the growing number of the learners who suffer from foreign language speaking anxiety (FLSA), it is becoming increasingly difficult to ignore its harmful outcomes on their performance and success, especially during their first contact with the pupils, as they will be teaching in the near future. Different researchers suggested different ways to minimize the negative effects of FLSA. The present study sheds light on emotional intelligence skills training as an effective strategy not only to influence public speaking success but also to help pre-service EFL teachers lessen their speaking anxiety and eventually to prepare them for their professional career. A quasi-experiment was used in order to examine the research hypothesis. We worked with two groups of third-year EFL students at Oum El Bouaghi University. The Foreign Language Classroom Anxiety Scale (FLCAS) and the Emotional Quotient Inventory (EQ-i) were used to collect data about the participants’ FLSA and EI levels. The analysis of the data has yielded that the assumption that there is a negative correlation between EI and FLSA was statistically validated by the Pearson Correlation Test, concluding that, the more emotionally intelligent the individual is the less anxious s/he will be. In addition, the lack of amelioration in the results of the control group and the noteworthy improvement in the experimental group results led us to conclude that EI skills training was an effective strategy in minimizing the FLSA level and therefore, we confirmed our research hypothesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence" title="emotional intelligence">emotional intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20intelligence%20skills%20training" title=" emotional intelligence skills training"> emotional intelligence skills training</a>, <a href="https://publications.waset.org/abstracts/search?q=EQ-I" title=" EQ-I"> EQ-I</a>, <a href="https://publications.waset.org/abstracts/search?q=FLCAS" title=" FLCAS"> FLCAS</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20language%20speaking%20anxiety" title=" foreign language speaking anxiety"> foreign language speaking anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-service%20EFL%20teachers" title=" pre-service EFL teachers"> pre-service EFL teachers</a> </p> <a href="https://publications.waset.org/abstracts/107739/emotional-intelligence-training-helping-non-native-pre-service-efl-teachers-to-overcome-speaking-anxiety-the-case-of-pre-service-teachers-of-english-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107739.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">140</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">7</span> Membrane Bioreactor for Wastewater Treatment and Reuse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Kitanou">Sarra Kitanou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water recycling and reuse is an effective measure to solve the water stress problem. The sustainable use of water resource has become a national development strategy in Morocco. A key aspect of improving overall sustainability is the potential for direct wastewater effluent reuse. However, the hybrid technology membrane bioreactors (MBR) have been identified as an attractive option for producing high quality and nutrient-rich effluents for wastewater treatment. It is based on complex interactions between biological processes, filtration process and rheological properties of the liquid to be treated. Currently, with the evolution of wastewater treatment projects in Morocco, the MBR technology can be used as a technology treating different types of wastewaters and to produce effluent with suitable quality for reuse. However, the energetic consumption of this process is a great concern, which can limit the development and implementation of this technology. In this investigation, the electric energy consumption of an ultrafiltration membrane bioreactor process in domestic wastewater treatment is evaluated and compared to some MBR installations based on literature review. Energy requirements of the MBR are linked to operational parameters and reactor performance. The analysis of energy consumption shows that the biological aeration and membrane filtration are more energy consuming than the other components listed as feed and recirculation pumps. Biological aeration needs 53% of the overall energetic consumption and the specific energy consumption for membrane filtration is about 25%. However, aeration is a major energy consumer, often exceeding 50% share of total energy consumption. The optimal results obtained on the MBR process (pressure p = 1.15 bar), hydraulic retention time (15 h) showed removal efficiencies up to 90% in terms of organic compounds removal, 100% in terms of suspended solids presence and up to 80% reduction of total nitrogen and total phosphorus. The effluent from this MBR system could be considered as qualified for irrigation reuse, showing its potential application in the future. <p class="card-text"><strong>Keywords:</strong> <a
