A good method for skin detection means a good and successful result of the system.

Considerable attention has been focused, in recent years, upon the field of biosorption which represents a biotechnological innovation as well as an excellent tool for removal of metal ions from aqueous effluents. So the purpose of this study is to valorize by-product which are orange peels and an extract of these peels (pectin; a heteropolysaccharide) in treatment of water containing heavy metals. All biosorption experiments were carried out at room temperature, an indicated pH, a precise amount of biosorbent and under continuous stirring. Biosorption kinetic was determined by evaluating the residual concentration of the metal ion at different time intervals using UV spectroscopy. The results obtained show that the orange peels and pectin are interesting biosorbents with maximum biosorption capacity of up to 140 mg/g. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=orange%20peels" title="orange peels">orange peels</a>, <a href="https://publications.waset.org/abstracts/search?q=pectin" title=" pectin"> pectin</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=biosorption" title=" biosorption"> biosorption</a> </p> <a href="https://publications.waset.org/abstracts/12733/biosorption-of-heavy-metals-from-aqueous-solutions-by-plant-biomass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12733.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">332</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1621</span> Optimisation of Extraction of Phenolic Compounds in Algerian Lavandula multifida, Algeria, NW</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20Mahmoud%20Dif">Mustapha Mahmoud Dif</a>, <a href="https://publications.waset.org/abstracts/search?q=Fouzia%20Benali-Toumi"> Fouzia Benali-Toumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Benyahia"> Mohamed Benyahia</a>, <a href="https://publications.waset.org/abstracts/search?q=Sofiane%20Bouazza"> Sofiane Bouazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbes%20Dellal"> Abbes Dellal</a>, <a href="https://publications.waset.org/abstracts/search?q=Slimane%20Baha"> Slimane Baha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> L. multifida is applied to treat rheumatism and cold and has hypoglycemic and anti-inflammatory properties. The present study is to optimize the extraction of phenolic compounds in Algerian Lavandula multifida. The influences of parameters including temperature (decoction and maceration) and extraction time (15min to 45 min) on the flavonoids concentration are studied. The optimal conditions are determined and the quadratic response surfaces draw from the mathematical models. Total phenols were evaluated using Folin sicaltieu methods, total flavonoids were estimated using the Tri chloral aluminum method. The maximum concentration extracted, for total flavonoids, equal to 0.043 mg/g was achieved with decoction and extraction time of 41.55 min. However, for total phenol compounds highest concentration of 0.218 mg/g, is obtained with 45 min at 49.99°C. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=L%20multifidi" title="L multifidi">L multifidi</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20content" title=" phenolic content"> phenolic content</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=time" title=" time"> time</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/46388/optimisation-of-extraction-of-phenolic-compounds-in-algerian-lavandula-multifida-algeria-nw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46388.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">420</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">1620</span> A Miniaturized Circular Patch Antenna Based on Metamaterial for WI-FI Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zahra%20Moussa">Fatima Zahra Moussa</a>, <a href="https://publications.waset.org/abstracts/search?q=Yamina%20Belhadef"> Yamina Belhadef</a>, <a href="https://publications.waset.org/abstracts/search?q=Souheyla%20Ferouani"> Souheyla Ferouani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we present a new form of miniature circular patch antenna based on CSRR metamaterials with an extended bandwidth proposed for 5 GHz Wi-Fiapplications.

In fact, the latest major earthquake that affected the Algiers-Boumerdes region in 2003 caused excessive levels of loss of life and property. Economic, social and environmental damage were also experienced. During the three days following the event, a relatively weak coordination of public authority was noted. Many localities did not receive any relief due to lack of information from concerned authorities and delay in connecting damaged roads. Following this event, Algerian government and civil society has recognized the urgent need for an appropriate and immediate seismic risk mitigation strategy. This paper describes procedures for emergency response following past earthquakes in Algeria and provides a brief review of risk mitigation activities since 1980. The paper also aims to provide measures to reduce earthquake risk through general strategy and practical implementation of the mitigation actions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake" title="earthquake">earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard" title=" hazard"> hazard</a>, <a href="https://publications.waset.org/abstracts/search?q=prevention" title=" prevention"> prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20reduction" title=" risk reduction"> risk reduction</a> </p> <a href="https://publications.waset.org/abstracts/29675/measures-for-earthquake-risk-reduction-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29675.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">529</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">1608</span> Static Relaxation of Glass Fiber Reinforced Pipes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Y.%20Abdellah">Mohammed Y.

With this purpose, we decided to investigate the coordination chemistry of the Schiff base. Along this way we were able to create cubane-like complexes and elaborate new Single Molecule-Magnets. The idea was to use Schiff base ligands and different metals to generate high nuclear complexes. Complexation of Shiff base with copper (II) has been investigated. Tetra nuclear complex with a cubane like core have been synthesized with (Sciff base), with the same base and cobalt (II) we obtain an other single magnetic complex completely different.

After the injection time about 15 to 20 minutes, the patient should eat a fatty meal and chocolate for the good excretion of the gall bladder, to evaluate the performance and regional wall motion of the left ventricle (LV). The results showed that the body mass index percentage in this sample was in range of 43.05 to 61.05. The number of patients who were catheter candidates were 56 with 43% and the patients that were not candidate to cathode were 74 patients with 57% of all patients. For the group of patients where type of ischemia was assessed, 29.5% of patients had reversible posterior and inferior wall, 15.1% of patients had fixed large from apex to base, 9.6% of patients had mild basal inferior wall, 4.8 % of patients had mild anterior wall, 6.2% of patients had antro-septal and 34.9% of patients had moderate ischemia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=myocardial%20ischemia" title="myocardial ischemia">myocardial ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20scintigraphy" title=" myocardial scintigraphy"> myocardial scintigraphy</a>, <a href="https://publications.waset.org/abstracts/search?q=contrast%20ventriculography" title=" contrast ventriculography"> contrast ventriculography</a>, <a href="https://publications.waset.org/abstracts/search?q=coronary%20artery%20obstruction" title=" coronary artery obstruction"> coronary artery obstruction</a> </p> <a href="https://publications.waset.org/abstracts/13957/characterization-of-coronary-artery-obstruction-and-related-findings-in-ischemic-heart-patients-using-cardiac-scintigraphy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13957.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">585</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">1604</span> Effect of Papaverine on Neurospheres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noura%20Shehab-Eldeen">Noura Shehab-Eldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elsherbeeny"> Mohamed Elsherbeeny</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Elmetwally"> Hossam Elmetwally</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salama"> Mohamed Salama</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Lotfy"> Ahmed Lotfy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elgamal"> Mohamed Elgamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Sheashaa"> Hussein Sheashaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sobh"> Mohamed Sobh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mitochondrial toxins including papaverine may be implicated in the etiology and pathogenesis of Parkinson's disease. 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">1603</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.

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">1598</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.

Model is consistent with an expected network of interconnected [MF6] polyhedra. The RMC results are accompanied by artificial satellite peaks. To remedy this problem, we use an extension of the RMC algorithm, which introduces an energy penalty term in acceptance criteria. This method is called the Hybrid Reverse Monte Carlo (HRMC) method. The idea of this paper is to apply the (HRMC) method to the title glasses, in order to make a study of the phenomenon nature of order and disorder by displaying and discussing the partial pair distribution functions (PDFs) g(r). We suggest that this method can be used to describe average correlations between components of fluoride glass or similar system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluoride%20glasses" title="fluoride glasses">fluoride glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=RMC%20simulation" title=" RMC simulation"> RMC simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20scattering" title=" neutron scattering"> neutron scattering</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20RMC%20simulation" title=" hybrid RMC simulation"> hybrid RMC simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Lennard-Jones%20potential" title=" Lennard-Jones potential"> Lennard-Jones potential</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20pair%20distribution%20functions" title=" partial pair distribution functions"> partial pair distribution functions</a> </p> <a href="https://publications.waset.org/abstracts/3016/study-of-the-phenomenon-nature-of-order-and-disorder-in-bamnfevf7-fluoride-glass-by-the-hybrid-reverse-monte-carlo-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3016.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">534</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">1596</span> Polyphenol and Antimicrobial Activity in Olive Oil from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamel%20Zemour">Kamel Zemour</a>, <a href="https://publications.waset.org/abstracts/search?q=Kada%20Mohamed%20Amine%20Chouhim"> Kada Mohamed Amine Chouhim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Mairif"> Mohamed Mairif</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadj%20Eddine%20Adda%20Ardjan"> Tadj Eddine Adda Ardjan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many recent studies show the positive effect of phenolic compounds in olive oil on health. They are known for their biological properties, where they have shown potential activity as an antioxidant, anti-inflammatory, and antimicrobial agents. However, this characteristic is rarely studied in olive oil from different regions of Algeria. Different samples collected from the western region of Algeria were evaluated for their polyphenol content, antioxidant activity, and antimicrobial effect. The obtained results demonstrated that this oil is rich in polyphenols and revealed high antimicrobial activity against Staphylococcus aureus and Escherichia coli. Finally, this study has highlighted the nutritional and pharmaceutical importance of olive oil grown in Algeria. <p class="card-text"><strong>Keywords:</strong> <a
