progression of MS are gender dependent. Indeed, the inflammation is more pronounced in women, but the neurodegeneration is more important in men. In addition, women have more sleep disorders while men suffer more from cognitive decline. These non-physical disorders can negatively affect postural balance and fall risk. However, no study has examined the difference between men and women in those physical parameters in MS. Our objective was to determine the effect gender difference on postural balance and fall risk in MS persons. Methods: Eight men and twelve women with relapsing remitting-MS participated in this study. The assessment includes a posturographic examination to assess static (with eyes opened (EO) and eyes closed (EC)) and dynamic (with EO) postural balance. Unipedal balance and fall risk were assessed by a clinical unipedal balance test and the Four Square Step Test, respectively. Sleep quality was assessed using Spiegel's questionnaire, and cognitive assessment was performed using the Montreal Cognitive Assessment (MoCA) and the Simple Reaction Time Test. Results: Compared to men, women showed an increase in CdPVm in static bipedal condition with EC (p=0.037; d=0.71) and a decrease in MoCA scores (p=0.028; d=1.06). No gender differences were found in the other tests. Discussion: Static postural balance was more impaired in women compared to men. This result could be explained by the more pronounced cognitive decline observed in women compared to men. Indeed, cognitive disorders have been shown to be predictive factors of postural balance impairment. Conclusion: women were less stable than men in the static condition, possibly due to their lower cognitive performance. This gender difference could be taken into account by therapists in training programs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title="multiple sclerosis">multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bipedal%20postural%20balance" title=" bipedal postural balance"> bipedal postural balance</a>, <a href="https://publications.waset.org/abstracts/search?q=fall%20risk" title=" fall risk"> fall risk</a>, <a href="https://publications.waset.org/abstracts/search?q=sleep%20disturbance" title=" sleep disturbance"> sleep disturbance</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20deficiency" title=" cognitive deficiency"> cognitive deficiency</a> </p> <a href="https://publications.waset.org/abstracts/148745/postural-balance-and-falls-risk-in-persons-with-multiple-sclerosis-effect-of-gender-differences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148745.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">98</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">46</span> Combined Effect of Gender Differences and Fatiguing Task on Unipedal Postural Balance and Functional Mobility in Adults with Multiple Sclerosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sonda%20Jallouli">Sonda Jallouli</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Hammouda"> Omar Hammouda</a>, <a href="https://publications.waset.org/abstracts/search?q=Imen%20Ben%20Dhia"> Imen Ben Dhia</a>, <a href="https://publications.waset.org/abstracts/search?q=Salma%20Sakka"> Salma Sakka</a>, <a href="https://publications.waset.org/abstracts/search?q=Chokri%20Mhiri"> Chokri Mhiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Habib%20Elleuch"> Mohamed Habib Elleuch</a>, <a href="https://publications.waset.org/abstracts/search?q=Abedlmoneem%20Yahia"> Abedlmoneem Yahia</a>, <a href="https://publications.waset.org/abstracts/search?q=Sameh%20Ghroubi"> Sameh Ghroubi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple sclerosis (MS) is characterized by gender differences with affecting women two to four times more than men, but the disease progression is faster and more severe in men. Fatigue represents one of the most frequent and disabling symptoms related to MS. Results of previous studies regarding gender differences in fatigue perception in MS persons are contradictory. Besides, fatigue has been shown to affect negatively postural balance and functional mobility in MS persons. However, no study has taken into account gender differences in the response of these physical parameters to a fatiguing protocol in MS persons. Given the reduction of autonomy due to the alteration of these parameters induced by fatigue and the importance of gender differences in postural balance training programs in fatigued men and women with MS, the aim of this study was to investigate the effect of gender difference on unipedal postural balance and functional mobility after performing a fatiguing task in MS adults. Methods: Eleven women (30.29 ± 7.99 years) and seven men (30.91 ± 8.19 years) with relapsing-remitting MS performed a fatiguing protocol: three sets of the 5×sit to stand test (5-STST), six-minute walk test (6MWT) followed by three sets of the 5-STST. Unipedal balance, functional mobility, and fatigue perception were measured prefatigue (T0) and post fatigue (T3) using a clinical unipedal balance test, timed up and go test (TUGT), and analogic visual scale of fatigue (VASF), respectively. Heart rate (HR) and rate of perceived exertion (RPE) were recorded before, during and after the fatiguing task. Results: Compared to women, men showed an impairment of unipedal balance on the dominant leg (p<0.001, d=0.52) and mobility (p<0.001, d=3) via reducing unipedal stance time and increasing duration of TUGT execution, respectively. No gender differences were observed in 6MWT, 5-STST, HR, RPE and VASF scores. Conclusion: Fatiguing protocol negatively affected unipedal postural balance and mobility only in men. These gender differences were inconclusive but can be taken into account in postural balance rehabilitation programs for persons with MS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20mobility" title="functional mobility">functional mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=fatiguing%20exercises" title=" fatiguing exercises"> fatiguing exercises</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title=" multiple sclerosis"> multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20differences" title=" sex differences"> sex differences</a>, <a href="https://publications.waset.org/abstracts/search?q=unipedal%20balance" title=" unipedal balance"> unipedal balance</a> </p> <a href="https://publications.waset.org/abstracts/146573/combined-effect-of-gender-differences-and-fatiguing-task-on-unipedal-postural-balance-and-functional-mobility-in-adults-with-multiple-sclerosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146573.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">138</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">45</span> Proposal for a Generic Context Meta-Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaouadi%20Imen">Jaouadi Imen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Djemaa%20Raoudha"> Ben Djemaa Raoudha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Abdallah%20Hanene"> Ben Abdallah Hanene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The access to relevant information that is adapted to users’ needs, preferences and environment is a challenge in many applications running.

In this paper, authors present the design of a robust H-infinity current controller for an 8/6 SRM with taking into account the nonlinearity of the SRM and with rejection of disturbances. The electromagnetic torque is indirectly regulated through the current controller. To show the performances of this control, a robustness analysis is performed by comparing the H-infinity and PI controller simulation results. This comparison demonstrates better performances for the presented controller.

In this paper, we present security issues of the Smart Grid architecture and we highlight open issues that will make the Smart Grid security a challenging research area in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20grids" title="smart grids">smart grids</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20meters" title=" smart meters"> smart meters</a>, <a href="https://publications.waset.org/abstracts/search?q=home%20area%20network" title=" home area network"> home area network</a>, <a href="https://publications.waset.org/abstracts/search?q=neighbor%20area%20network" title=" neighbor area network"> neighbor area network</a> </p> <a href="https://publications.waset.org/abstracts/35303/smart-grids-cyber-security-issues-and-challenges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35303.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">424</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">39</span> Survivable IP over WDM Network Design Based on 1 ⊕ 1 Network Coding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihed%20Bahria%20El%20Asghar">Nihed Bahria El Asghar</a>, <a href="https://publications.waset.org/abstracts/search?q=Imen%20Jouili"> Imen Jouili</a>, <a href="https://publications.waset.org/abstracts/search?q=Mounir%20Frikha"> Mounir Frikha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inter-datacenter transport network is very bandwidth and delay demanding. The data transferred over such a network is also highly QoS-exigent mostly because a huge volume of data should be transported transparently with regard to the application user. To avoid the data transfer failure, a backup path should be reserved. No re-routing delay should be observed. A dedicated 1+1 protection is however not applicable in inter-datacenter transport network because of the huge spare capacity. In this context, we propose a survivable virtual network with minimal backup based on network coding (1 ⊕ 1) and solve it using a modified Dijkstra-based heuristic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20coding" title="network coding">network coding</a>, <a href="https://publications.waset.org/abstracts/search?q=dedicated%20protection" title=" dedicated protection"> dedicated protection</a>, <a href="https://publications.waset.org/abstracts/search?q=spare%20capacity" title=" spare capacity"> spare capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-datacenters%20transport%20network" title=" inter-datacenters transport network"> inter-datacenters transport network</a> </p> <a href="https://publications.waset.org/abstracts/44625/survivable-ip-over-wdm-network-design-based-on-1-1-network-coding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44625.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">447</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">38</span> Social Innovation Rediscovered: An Analysis of Empirical Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imen%20Douzi">Imen Douzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Ben%20Kahla"> Karim Ben Kahla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In spite of the growing attention for social innovation, it is still considered to be in a stage of infancy with minimal progress in theory development. Upon examining the field of study, one would have to conclude that, over the past two decades, academic research has focused primarily on establishing a conceptual foundation. This has resulted in a considerable stream of conceptual papers which have outnumbered empirical articles. Nevertheless, despite its growing popularity, scholars and practitioners are far from reaching a consensus as to what social innovation actually means which resulted in competing definitions and approaches within the field of social innovation and lack of unifying conceptual framework. This paper reviews empirical research studies on social innovation, classifies them along three dimensions and summarizes research findings for each of these dimensions. Preliminary to the analysis of empirical researches, an overview of different perspectives of social innovation is presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analysis%20of%20empirical%20research" title="analysis of empirical research">analysis of empirical research</a>, <a href="https://publications.waset.org/abstracts/search?q=definition" title=" definition"> definition</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20research" title=" empirical research"> empirical research</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20innovation%20perspectives" title=" social innovation perspectives"> social innovation perspectives</a> </p> <a href="https://publications.waset.org/abstracts/38783/social-innovation-rediscovered-an-analysis-of-empirical-research" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38783.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">384</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">37</span> Improvement of Thermal Comfort Conditions in an Urban Space "Case Study: The Square of Independence, Setif, Algeria"</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ballout%20Amor">Ballout Amor</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasmina%20Bouchahm"> Yasmina Bouchahm</a>, <a href="https://publications.waset.org/abstracts/search?q=Lacheheb%20Dhia%20Eddine%20Zakaria"> Lacheheb Dhia Eddine Zakaria</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several studies all around the world were conducted on the phenomenon of the urban heat island, and referring to the results obtained, one of the most important factors that influence this phenomenon is the mineralization of the cities which means the reducing of evaporative urban surfaces, replacing vegetation and wetlands with concrete and asphalt. The use of vegetation and water can change the urban environment and improve comfort, thus reduce the heat island. The trees act as a mask to the sun, wind, and sound, and also as a source of humidity which reduces air temperature and surrounding surfaces. Water also acts as a buffer to noise; it is also a source of moisture and regulates temperature not to mention the psychological effect on humans. Our main objective in this paper is to determine the impact of vegetation, ponds and fountains on the urban micro climate in general and on the thermal comfort of people along the Independence square in the Algerian city of Sétif, which is a semi-arid climate, in particularly. In order to reach this objective, a comparative study between different scenarios has been done; the use of the Envi-met program enabled us to model the urban environment of the Independence Square and to study the possibility of improving the conditions of comfort by adding an amount of vegetation and water ponds. After studying the results obtained (temperature, relative humidity, wind speed, PMV and PPD indicators), the efficiency of the additions we've made on the square was confirmed and this is what helped us to confirm our assumptions regarding the terms of comfort in the studied site, and in the end we are trying to develop recommendations and solutions which may contribute to improve the conditions for greater comfort in the Independence square. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comfort%20in%20outer%20space" title="comfort in outer space">comfort in outer space</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20environment" title=" urban environment"> urban environment</a>, <a href="https://publications.waset.org/abstracts/search?q=scenarisation" title=" scenarisation"> scenarisation</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetation" title=" vegetation"> vegetation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20ponds" title=" water ponds"> water ponds</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20square" title=" public square"> public square</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/18807/improvement-of-thermal-comfort-conditions-in-an-urban-space-case-study-the-square-of-independence-setif-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18807.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">454</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">36</span> Hepatoprotective Effect of Mycophenolate Mofetil against Tacrolimus Exposure in Rat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferjani%20Hanen">Ferjani Hanen</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Arem%20Amira"> El Arem Amira</a>, <a href="https://publications.waset.org/abstracts/search?q=Boussema%20Ayed%20Imen"> Boussema Ayed Imen</a>, <a href="https://publications.waset.org/abstracts/search?q=Bacha%20Hassen"> Bacha Hassen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tacrolimus (TAC), a calcineurin inhibitor, is clinically used as an immunosuppressive agent in the transplant recipient, but its use associated-hepatotoxicity. Mycophenolate mofetil (MMF), an anti-metabolite, is a potent immunosuppressive drug. MMF is not hepatotoxic and is the most common adjunctive immunosuppressant for TAC. The effects of TAC and MMF combination in the liver is still not well understood. This work aimed to investigate their combined effect against in liver in rats Wistar after 24 h. The oral median lethal doses (LD50) of TAC and MMF alone were evaluated in rats are 240 mg/kg and 500 mg/kg respectively. Oral administration of the MMF at 50 mg/kg to male Wistar intoxicated with TAC at 60 mg/kg, demonstrated a significant protective effect by lowering the levels of hepatic markers enzymes (AST, ALT) in the serum rat. MMF attenuated oxidative stress by restoring the activities of SOD, CAT and by reducing the malondialdehyde (MDA) and protein carbonyl levels liver. This study provided evidence that MMF protects rat liver from TAC-induced injury and suggests a most combination use for organ transplantation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tacrolimus" title="tacrolimus">tacrolimus</a>, <a href="https://publications.waset.org/abstracts/search?q=mycophenolate%20mofetil" title=" mycophenolate mofetil"> mycophenolate mofetil</a>, <a href="https://publications.waset.org/abstracts/search?q=combination" title=" combination"> combination</a>, <a href="https://publications.waset.org/abstracts/search?q=liver" title=" liver"> liver</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a> </p> <a href="https://publications.waset.org/abstracts/26359/hepatoprotective-effect-of-mycophenolate-mofetil-against-tacrolimus-exposure-in-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26359.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">336</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">35</span> A Custom Convolutional Neural Network with Hue, Saturation, Value Color for Malaria Classification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazala%20Hcini">Ghazala Hcini</a>, <a href="https://publications.waset.org/abstracts/search?q=Imen%20Jdey"> Imen Jdey</a>, <a href="https://publications.waset.org/abstracts/search?q=Hela%20Ltifi"> Hela Ltifi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Malaria disease should be considered and handled as a potential restorative catastrophe.

We performed multiple forms, counting a classification approach using the Hue, Saturation, Value (HSV) color space. HSV is used since of its superior ability to speak to image brightness; at long last, for classification, a convolutional neural network (CNN) architecture is created. Clusters of focus were used to deliver the classification. The highlights got to be forbidden, and a few more clamor sorts are included in the information.

The physico chemical characteristics: acidity (0,73%), peroxide value (14, 16 meqO2/kg oil) and iodine value (74,08 g iodine/100 g of oil) are consistent with international standards. The dosage of FA revealed a wealth of oil with UFA (76,7%), mainly composed of 65.43% of MUFA whose major fatty acid is oleic acid (63,57%). The experiment on rats receiving a diet rich in saturated fats and hydrogenated oils revealed that the consumption of Oleaster oil at the dose of 10 g and 20 g for 15 and 30 days improves plasma lipid profile by decreasing the rates of TC, TG, TL, and LDL-C with an increase in the rate of HDL-C serum. The importance of these effects depends on the dose and period of treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oleaster%20oil" title="oleaster oil">oleaster oil</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid" title=" fatty acid"> fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=Olea%20europea" title=" Olea europea"> Olea europea</a>, <a href="https://publications.waset.org/abstracts/search?q=oleic%20acid" title=" oleic acid"> oleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20profile" title=" lipid profile"> lipid profile</a> </p> <a href="https://publications.waset.org/abstracts/14746/physicochemical-and-biochemical-characterization-of-olea-europea-var-oleaster-oil-and-determination-of-its-effects-on-blood-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14746.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">488</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">32</span> Core Number Optimization Based Scheduler to Order/Mapp Simulink Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20Rebaya">Asma Rebaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Imen%20Amari"> Imen Amari</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaouther%20Gasmi"> Kaouther Gasmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Salem%20Hasnaoui"> Salem Hasnaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over these last years, the number of cores witnessed a spectacular increase in digital signal and general use processors.

InP, InP/ZnS core/shell and InP/ZnS/ZnS core/shell/shell Quantum Dots (QDs) were synthetized by the hot injection method. The optical and structural properties of the core InP QDs, InP/ZnS QDs, and InP/ZnS/ZnS QDs have being considered by several techniques such as X-ray diffraction, transmission electron microscopy, optical spectroscopy, and photoluminescence. The average diameter of InP, InP/ZnS, and InP/ZnS/ZnS Quantum Dots (QDs) was varying between 10 nm, 5.4 nm, and 4.10 nm. This experience revealed that the surface morphology of the Quantum Dots has a more regular spherical form with color variation of the QDs in solution. The emission peak of colloidal InP Quantum Dots was around 530 nm, while in InP/ZnS, the emission peak is displayed and located at 598 nm. whilst for InP/ZnS/ZnS is placed at 610 nm. Furthermore, an enhanced PL emission due to a passivation effect in the ZnS-covered InP QDs was obtained. Add the XRD information FWHM of the principal peak of InP QDs was 63 nm, while for InP/ZnS was 41 nm and InP/ZnS/ZnS was 33 nm. The effect of the Zinc stearate precursor concentration on the optical, structural, surface chemical of InP and InP/ZnS and InP/ZnS/ZnS QDs will be discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indium%20phosphide" title="indium phosphide">indium phosphide</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20dot" title=" quantum dot"> quantum dot</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title=" nanoparticle"> nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=core-shell" title=" core-shell"> core-shell</a>, <a href="https://publications.waset.org/abstracts/search?q=multishell" title=" multishell"> multishell</a>, <a href="https://publications.waset.org/abstracts/search?q=luminescence" title=" luminescence"> luminescence</a> </p> <a href="https://publications.waset.org/abstracts/145518/inpzns-core-shell-and-inpznszns-core-multishell-quantum-dots-for-improved-luminescence-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145518.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">165</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">29</span> Autoimmune Diseases Associated to Autoimmune Hepatitis: A Retrospective Study of 24 Tunisian Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soumaya%20Mrabet">Soumaya Mrabet</a>, <a href="https://publications.waset.org/abstracts/search?q=Imen%20Akkari"> Imen Akkari</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Atig"> Amira Atig</a>, <a href="https://publications.waset.org/abstracts/search?q=Elhem%20Ben%20Jazia"> Elhem Ben Jazia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease of unknown cause. Concomitant autoimmune disorders have been described in 30–50% of patients with AIH. The aim of our study is to determine the prevalence and the type of autoimmune disorders associated with AIH. Material and Methods: It is a retrospective study over a period of 16 years (2000-2015) including all patients followed for AIH. The diagnosis of AHI was based on the criteria of the revised International AIH group scoring system (IAIHG). Results: Twenty-for patients (21 women and 3 men) followed for AIH were collected. The mean age was 39 years (17-65 years). Among these patients, 11 patients(45.8%) had at least one autoimmune disease associated to AIH. These diseases were Hashimoto's thyroiditis (n = 5), Gougerot Sjogren syndrome (n=5), Primary biliary cirrhosis (n=2), Primitive sclerosant Cholangitis (n=1), Addison disease (n = 1) and systemic sclerosis (n=1). Patients were treated with corticosteroids alone or with azathioprine associated to the specific treatment of associated diseases with complete remission of AIH in 90% of cases and clinical improvement of other diseases. Conclusion: In our study, the prevalence of autoimmune diseases in AIH patients was 45.8%. These diseases were dominated by autoimmune thyroiditis and Gougerot Sjogren syndrome. The investigation of autoimmune diseases in autoimmune hepatitis must be systematic because of their frequency and the importance of adequate management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autoimmune%20diseases" title="autoimmune diseases">autoimmune diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=autoimmune%20hepatitis" title=" autoimmune hepatitis"> autoimmune hepatitis</a>, <a href="https://publications.waset.org/abstracts/search?q=autoimmune%20thyroiditis" title=" autoimmune thyroiditis"> autoimmune thyroiditis</a>, <a href="https://publications.waset.org/abstracts/search?q=gougerot%20sjogren%20syndrome" title=" gougerot sjogren syndrome"> gougerot sjogren syndrome</a> </p> <a href="https://publications.waset.org/abstracts/66018/autoimmune-diseases-associated-to-autoimmune-hepatitis-a-retrospective-study-of-24-tunisian-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66018.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">263</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">28</span> Macroscopic Study of Reproductive Pathologies in Cows at the Souk-Ahras Communal Slaughterhouse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Besma%20Abdeltif">Besma Abdeltif</a>, <a href="https://publications.waset.org/abstracts/search?q=Chebabhi%20Imen"> Chebabhi Imen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: it is important to define the genital pathologies encountered in Algeria in postpartum dairy cows. The objective was to identify the different pathologies of reproduction in cows found at the communal abattoir of Souk Ahras. Materials and Methods: Our study was carried at the communal slaughterhouse of Souk-Ahras on 63 genital tracts were examined macroscopically after slaughter. Results: The results obtained reveal a high frequency of pregnant females (14.28%), most of the gestations were at their beginning. Uterine anomalies ranked first in the genital lesions of the cow (20.37%). The frequencies of these abnormalities are in ascending order: aplasia of the horns = 1.85%, traumatic cervical = 1.85%, cervical tumors = 1.85%, chronic endometritis = 3.70% and Acute endometritis = 11.11%. The ovarian cyst is the most common lesion, with a frequency of 3.70%, followed by smooth ovaries (1.85%). These are single, thin-walled cysts more present on the right ovary than the left ovary. Salpingitis is the only tubal lesion found on 5.55% of the non-pregnant genital tract. Neoformation is the only vaginal lesion identified in this work (1.85%).

After that, we use pair-copula to find the optimal portfolio risk dependence structure. Finally, with Monte Carlo simulations, we estimate the Value at Risk (VaR) and the conditional Value at Risk (CVaR). The empirical results show the VaR and CVaR values for an equally weighted portfolio of Dow Jones Islamic-conventional pairs. In sum, we found that the optimal investment focuses on Islamic-conventional US Market index pairs because of high investment proportion; however, all other index pairs have low investment proportion.

'Stress-timed' languages are exemplified by English, 'syllable-timed' languages by French and 'mora-timed' languages by Japanese. However, to our best knowledge, acoustic studies have not been unanimous in strictly establishing which rhythm category a given language belongs to and failed to show empirical evidence for isochrony. Perception seems to be a good approach to categorize languages into different rhythm classes. This study, within the scope of experimental phonetics, includes an account of different perceptual experiments using cues from natural and inverted speech, as well as pitch extracted from speech data. It is an attempt to categorize speech rhythm over a large set of Arabic (Tunisian, Algerian, Lebanese and Moroccan) and English dialects (Welsh, Irish, Scottish and Texan) as well as other languages such as Chinese, Japanese, French, and German. Listeners managed to classify the different languages and dialects into different rhythm classes using suprasegmental cues mainly rhythm and pitch (F0). They also perceived rhythmic differences even among languages and dialects belonging to the same rhythm class. This may show that there are different subclasses within very broad rhythmic typologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=F0" title="F0">F0</a>, <a href="https://publications.waset.org/abstracts/search?q=inverted%20speech" title=" inverted speech"> inverted speech</a>, <a href="https://publications.waset.org/abstracts/search?q=mora-timing" title=" mora-timing"> mora-timing</a>, <a href="https://publications.waset.org/abstracts/search?q=rhythm%20variation" title=" rhythm variation"> rhythm variation</a>, <a href="https://publications.waset.org/abstracts/search?q=stress-timing" title=" stress-timing"> stress-timing</a>, <a href="https://publications.waset.org/abstracts/search?q=syllable-timing" title=" syllable-timing"> syllable-timing</a> </p> <a href="https://publications.waset.org/abstracts/78217/speech-rhythm-variation-in-languages-and-dialects-f0-natural-and-inverted-speech" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78217.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">526</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> Deep Learning Based-Object-classes Semantic Classification of Arabic Texts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imen%20Elleuch">Imen Elleuch</a>, <a href="https://publications.waset.org/abstracts/search?q=Wael%20Ouarda"> Wael Ouarda</a>, <a href="https://publications.waset.org/abstracts/search?q=Gargouri%20Bilel"> Gargouri Bilel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We proposes in this paper a Deep Learning based approach to classify text in order to enrich an Arabic ontology based on the objects classes of Gaston Gross.

We have applied our proposed approach on a corpus constructed from an Arabic dictionary. The obtained semantic classification of text will enrich the Arabic objects classes ontology. In fact, new classes can be added to the ontology or an expansion of the features that characterizes each object class can be updated.

This is one of the most valuable softwood, both economically, ecologically, aesthetically and culturally. In Algeria, the cedar forests currently have worrying symptoms of decline which therefore require special monitoring. Fungal endophytes are involved in various diseases of the Atlas cedar. They attack all organs on which they cause many symptoms. These microflora live in complex interaction with plants. In this study, we identified a total of 09 mycotaxons collected needles Cedarwood at three stations with different degrees of decline (Talmet, Boumerzoug and Tuggurt) in the National Park Belezma (Batna, Algeria). The study conducted on a total of 12 trees were identified 08 mycoendophytes in Talmet station, 04 species in the Boumerzoug station and 03 in Tuggurt station. The total species richness mycoendophytes depending on the types of cedar forests showed that the largest diversity was recorded at the cedar forest healthy, Alternaria is the most common type in all stations. This work should be completed by further detailed studies to identify other endophyte species and better know its interactions with the Atlas cedar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cedrus%20atlantica" title="Cedrus atlantica">Cedrus atlantica</a>, <a href="https://publications.waset.org/abstracts/search?q=endophytic%20fungi" title=" endophytic fungi"> endophytic fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=microflora" title=" microflora"> microflora</a>, <a href="https://publications.waset.org/abstracts/search?q=mycotaxons" title=" mycotaxons"> mycotaxons</a>, <a href="https://publications.waset.org/abstracts/search?q=mycoendophyte" title=" mycoendophyte"> mycoendophyte</a> </p> <a href="https://publications.waset.org/abstracts/31488/study-of-the-microflora-of-cedar-forests-with-different-degrees-of-decline-in-the-national-park-belezma-batna-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31488.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">346</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">23</span> Zooplankton Health Status Monitoring in Bir Mcherga Dam (Tunisia)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabria%20Barka">Sabria Barka</a>, <a href="https://publications.waset.org/abstracts/search?q=Imen%20Gdara"> Imen Gdara</a>, <a href="https://publications.waset.org/abstracts/search?q=Zouhour%20Ouan%C3%A8s"> Zouhour Ouanès</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20Mouelhi"> Samia Mouelhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Monia%20El%20Bour"> Monia El Bour</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Hamza-Chaffai"> Amel Hamza-Chaffai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Because dams are large semi-closed reservoirs of pollutants originating from numerous anthropogenic activities, they represent a threat to aquatic life and they should be monitored. The present work aims to use freshwater zooplankton (Copepods and Cladocerans) in order to evaluate the environmental health status of Bir M'cherga dam in Tunisia. Animals were collected in situ monthly between October and August. Genotoxicity (micronucleus test), neurotoxicity (acetylcholinesterase, AChE) and oxidative stress (catalase, CAT and malondialdehyde, MDA) biomarkers were analyzed in zooplankton. High frequencies of micronucleus were observed in zooplankton cells during summer. AChE activities were inhibited during early winter and summer. CAT and MDA biomarker levels showed high seasonal variability, suggesting that animals are permanently exposed to multiple oxidative stress. The results of this study suggest that the Bir Mcherga dam is subject to continuous multi-origin stress, probably amplified by abiotic parameters. It is then recommended to urgently monitor freshwater environments in Tunisia, especially those used for irrigation and consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biomonitoring" title="Biomonitoring">Biomonitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=Bir%20Mcherga%20Dam" title=" Bir Mcherga Dam"> Bir Mcherga Dam</a>, <a href="https://publications.waset.org/abstracts/search?q=cladocerans" title=" cladocerans"> cladocerans</a>, <a href="https://publications.waset.org/abstracts/search?q=copepods" title=" copepods"> copepods</a>, <a href="https://publications.waset.org/abstracts/search?q=freshwater%20zooplankton" title=" freshwater zooplankton"> freshwater zooplankton</a>, <a href="https://publications.waset.org/abstracts/search?q=genotoxicity" title=" genotoxicity"> genotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=neurotoxicity" title=" neurotoxicity"> neurotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/171979/zooplankton-health-status-monitoring-in-bir-mcherga-dam-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171979.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">82</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> The Residential Subdivision under the Influence of the Unfinished Densification, Case Study for Subdivisions in Setif, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lacheheb%20Dhia%20Eddine%20Zakaria">Lacheheb Dhia Eddine Zakaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Ballout%20Amor"> Ballout Amor </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, it is necessary to be thrifty for its planet, on one hand the space being a rare, nonrenewable resource, and on the other hand the ecological, economic and social cost of the urban sprawl. It is commonly asserted that the promotion of a more compact and dense city has a positive effect in terms of public costs of investment, functioning and costs for the citizens and the users of the city. It is clear that the modes urban development management have to evolve profoundly, in particular towards a densification favourable to the raising of the urban quality through an ideal urban density on the scale of the individual housing estate. The lot as an individual housing estate was adopted as an alternative development model to the collective housing, thought in an anthropocentric perspective to emerge as a quality model where the density plays an important role, by being included in operations of a global coherence, in an optimal organization without forgetting the main importance of the deadlines of construction and the finalization of the works. The image of eternal construction site inflicted to our cities explains the renewed interest for the application of the regulatory framework and the completion of these limited operations without global coherence, which are summed up in our case to a ground cut in plots of land, sold then built independently without being finished, and support the relevance of the essential question of the improvement of the outside aspect bound to the appearance which can be revealed as a so important factor for a better use and a better acceptance of its housing environment, that the ratio of a number of houses on a plot of land or the number of square meters by house. To demonstrate the impact of the completion degree of the subdivision dwellings, roads system and urban public utilities on the density or the densification and therefore on the urban quality, we studied two residential subdivisions, the private subdivision Sellam and the subdivision El Imane with a common situation, and a different land surface, density and cutting, being occupied by various social classes, with different needs and different household average size. The approach of this work is based on the typo morphological analysis to reveal the differences in the degrees of completions of the subdivision’s built environment and on the investigation, by a household’s survey, to demonstrate importance of the degree of completion and to reveal the conditions of qualitative densification favourable and convenient to a better subdivision’s appropriation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=subdivision" title="subdivision">subdivision</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20completion" title=" degree of completion"> degree of completion</a>, <a href="https://publications.waset.org/abstracts/search?q=densification" title=" densification"> densification</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20quality" title=" urban quality"> urban quality</a> </p> <a href="https://publications.waset.org/abstracts/25603/the-residential-subdivision-under-the-influence-of-the-unfinished-densification-case-study-for-subdivisions-in-setif-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25603.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">372</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">21</span> Synthesis of Flavonoid Derivatives Precursors of Active Pharmaceutical Ingredients by Mechanical Chemistry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imen%20Abid">Imen Abid</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachel%20Calvet"> Rachel Calvet</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Baltas"> Michel Baltas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flavonoids are secondary metabolites that belong to a polyphenolic class, present in fruits and vegetables, playing a significant role in biological systems. The structural variations of these flavonoids are associated with many biological and pharmacological activities (antioxidant, anti-inflammatory, anticancer, antibacterial, antifungal, antiviral, and antimalarial). Given their importance in plants and health-promoting roles in humans, significant efforts have been devoted towards their isolation of flavonoids and chemical elaboration (organic synthesis). But with the increasing public concern over environmental degradation and future resources, it is of great importance for chemists to come up with different approaches, less hazardous to human health and the environment. Being employed in large amounts, the solvents used in organic synthesis are high on the list of environmental pollutants. To overcome these problems, our approach is to develop unconventional processes involving solvent-free conditions. The application of mechanical forces to solvent-free or solvent-less reaction mixtures through the use of ball mills offers many advantages over traditional solvent-based strategies. It is one of the unconventional activation methods, which makes it possible to overcome the use of solvents, in the context of green chemistry and more respectful of the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20synthesis" title="organic synthesis">organic synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title=" green chemistry"> green chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=mecanochemistry" title=" mecanochemistry"> mecanochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20molecules" title=" pharmaceutical molecules"> pharmaceutical molecules</a> </p> <a href="https://publications.waset.org/abstracts/168281/synthesis-of-flavonoid-derivatives-precursors-of-active-pharmaceutical-ingredients-by-mechanical-chemistry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168281.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">79</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">20</span> A Fuzzy Inference Tool for Assessing Cancer Risk from Radiation Exposure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bouharati%20Lokman">Bouharati Lokman</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouharati%20Imen"> Bouharati Imen</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouharati%20Khaoula"> Bouharati Khaoula</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouharati%20Oussama"> Bouharati Oussama</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouharati%20Saddek"> Bouharati Saddek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ionizing radiation exposure is an established cancer risk factor. Compared to other common environmental carcinogens, it is relatively easy to determine organ-specific radiation dose and, as a result, radiation dose-response relationships tend to be highly quantified. Nevertheless, there can be considerable uncertainty about questions of radiation-related cancer risk as they apply to risk protection and public policy, and the interpretations of interested parties can differ from one person to another. Examples of tools used in the analysis of the risk of developing cancer due to radiation are characterized by uncertainty. These uncertainties are related to the history of exposure and different assumptions involved in the calculation. We believe that the results of statistical calculations are characterized by uncertainty and imprecision. Having regard to the physiological variation from one person to another. In this study, we develop a tool based on fuzzy logic inference. As fuzzy logic deals with imprecise and uncertain, its application in this area is adequate. We propose a fuzzy system with three input variables (age, sex and body attainable cancer). The output variable expresses the risk of infringement rate of each organ. A base rule is established from recorded actual data. After successful simulation, this will instantly predict the risk of infringement rate of each body following chronic exposure to 0.1 Gy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radiation%20exposure" title="radiation exposure">radiation exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a> </p> <a href="https://publications.waset.org/abstracts/50201/a-fuzzy-inference-tool-for-assessing-cancer-risk-from-radiation-exposure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50201.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">311</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">19</span> The Effect of Temperature and Salinity on the Growth and Carotenogenesis of Three Dunaliella Species (Dunaliella sp.

The aim of this research was to compare carotenoids, and β-carotene production were investigated in a batch those 3 species. Therefore 2 stress factors were used: 2 different temperatures (20°C and 30°C) and 2 different salinities (30&permil;, and 60&permil;) were tested over a 17-day study. The highest growth and chlorophyll <em>a</em> was reported for <em>Dunaliella </em>sp. under 20°C/30&permil; and 20°C/60&permil; conditions respectively followed by <em>D. bardawil</em> and <em>D. salina</em>. Significant differences were noticed (p<0.05) for the other 3 species. The growth decreased as temperature and salinity increased since the lowest growth was noticed for the 30°C/60&permil; group. The chlorophyll <em>a</em> content decreased also as temperature increased however when the NaCl concentration increased an augmentation of the content was noticed . In the 17<sup>th</sup> day of experiment the highest carotenoids concentration was reported for <em>D. bardawil </em>20°C/30&permil; (65,639±0,400 μg.mL<sup>−</sup><sup>1</sup>) and the most important β carotene concentration was for <em>D</em>. <em>salina</em> 20°C/60&permil; (8,98E-07±0,013 mol/L). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dunaliella%20sp." title="Dunaliella sp.">Dunaliella sp.</a>, <a href="https://publications.waset.org/abstracts/search?q=Dunaliella%20salina" title=" Dunaliella salina"> Dunaliella salina</a>, <a href="https://publications.waset.org/abstracts/search?q=Dunaliella%20bardawil" title=" Dunaliella bardawil"> Dunaliella bardawil</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=pigments" title=" pigments"> pigments</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20factors" title=" stress factors"> stress factors</a> </p> <a href="https://publications.waset.org/abstracts/69056/the-effect-of-temperature-and-salinity-on-the-growth-and-carotenogenesis-of-three-dunaliella-species-dunaliella-sp-lake-isolate-d-salina-ccap-1918-and-d-bardawil-lb-2538-cultivated-under-laboratory-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69056.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">315</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> A Hybrid Algorithm Based on Greedy Randomized Adaptive Search Procedure and Chemical Reaction Optimization for the Vehicle Routing Problem with Hard Time Windows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imen%20Boudali">Imen Boudali</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Ragmoun"> Marwa Ragmoun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Vehicle Routing Problem with Hard Time Windows (VRPHTW) is a basic distribution management problem that models many real-world problems. The objective of the problem is to deliver a set of customers with known demands on minimum-cost vehicle routes while satisfying vehicle capacity and hard time windows for customers. In this paper, we propose to deal with our optimization problem by using a new hybrid stochastic algorithm based on two metaheuristics: Chemical Reaction Optimization (CRO) and Greedy Randomized Adaptive Search Procedure (GRASP). The first method is inspired by the natural process of chemical reactions enabling the transformation of unstable substances with excessive energy to stable ones. During this process, the molecules interact with each other through a series of elementary reactions to reach minimum energy for their existence. This property is embedded in CRO to solve the VRPHTW. In order to enhance the population diversity throughout the search process, we integrated the GRASP in our method. Simulation results on the base of Solomon’s benchmark instances show the very satisfactory performances of the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a
