Usually, these sensor nodes are massively and deployed randomly as in Ad-hoc over hostile and harsh environment to sense, collect and transmit data to the needed locations (i.e., base station). One of the main advantages of WSN is that the ability to work in unattended and scattered environments regardless the presence of humans such as remote active volcanoes environments or earthquakes. In WSN expanding network, lifetime is a major concern. Clustering technique is more important to maximize network lifetime. Nature-inspired algorithms are developed and optimized to find optimized solutions for various optimization problems.

Genetic Algorithm (GA) considered as one of optimization methods used to solve Travel salesman Problem (TSP). The feasibility of GA in finding a TSP solution is dependent on GA operators; encoding method, population size, termination criteria, in general. In specific, crossover and its probability play a significant role in finding possible solutions for Symmetric TSP (STSP). In addition, the crossover should be determined and enhanced in term reaching optimal or at least near optimal. In this paper, we spot the light on using a modified crossover method called modified sequential constructive crossover and its impact on reaching optimal solution. To justify the relevance of a parameter value in solving the TSP, a set comparative analysis conducted on different crossover methods values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=crossover" title=" crossover"> crossover</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation" title=" mutation"> mutation</a>, <a href="https://publications.waset.org/abstracts/search?q=TSP" title=" TSP"> TSP</a> </p> <a href="https://publications.waset.org/abstracts/81306/impact-of-population-size-on-symmetric-travelling-salesman-problem-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81306.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">227</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> Gas Transmission Pipeline Integrity Management System Through Corrosion Mitigation and Inspection Strategy: A Case Study of Natural Gas Transmission Pipeline from Wafa Field to Mellitah Gas Plant in Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osama%20Sassi">Osama Sassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Manal%20Eltorki"> Manal Eltorki</a>, <a href="https://publications.waset.org/abstracts/search?q=Iftikhar%20Ahmad"> Iftikhar Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Poor integrity is one of the major causes of leaks and accidents in gas transmission pipelines. To ensure safe operation, it is must to have efficient and effective pipeline integrity management (PIM) system. The corrosion management is one of the important aspects of successful pipeline integrity management program together design, material selection, operations, risk evaluation and communication aspects to maintain pipelines in a fit-for-service condition. The objective of a corrosion management plan is to design corrosion mitigation, monitoring, and inspection strategy, and for maintenance in a timely manner. This paper presents the experience of corrosion management of a gas transmission pipeline from Wafa field to Mellitah gas plant in Libya. The pipeline is 525.5 km long and having 32 inches diameter. It is a buried pipeline. External corrosion on pipeline is controlled with a combination of coatings and cathodic protection while internal corrosion is controlled with a combination of chemical inhibitors, periodic cleaning and process control. The monitoring and inspection techniques provide a way to measure the effectiveness of corrosion control systems and provide an early warning when changing conditions may be causing a corrosion problem. This paper describes corrosion management system used in Mellitah Oil & Gas BV for its gas transmission pipeline based on standard practices of corrosion mitigation and inspection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion%20mitigation%20on%20gas%20transmission%20pipelines" title="corrosion mitigation on gas transmission pipelines">corrosion mitigation on gas transmission pipelines</a>, <a href="https://publications.waset.org/abstracts/search?q=pipeline%20integrity%20management" title=" pipeline integrity management"> pipeline integrity management</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20management%20of%20gas%20pipelines" title=" corrosion management of gas pipelines"> corrosion management of gas pipelines</a>, <a href="https://publications.waset.org/abstracts/search?q=prevention%20and%20inspection%20of%20corrosion" title=" prevention and inspection of corrosion"> prevention and inspection of corrosion</a> </p> <a href="https://publications.waset.org/abstracts/178928/gas-transmission-pipeline-integrity-management-system-through-corrosion-mitigation-and-inspection-strategy-a-case-study-of-natural-gas-transmission-pipeline-from-wafa-field-to-mellitah-gas-plant-in-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178928.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">76</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> Study of the Vertical Handoff in Heterogeneous Networks and Implement Based on Opnet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Benaatou">Wafa Benaatou</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnane%20Latif"> Adnane Latif </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this document we studied more in detail the Performances of the vertical handover in the networks WLAN, WiMAX, UMTS before studying of it the Procedure of Handoff Vertical, the whole buckled by simulations putting forward the performances of the handover in the heterogeneous networks.

The study implements a mixed methods approach. First, a questionnaire was administered to 64 students from two schools in Almadinah, a Saudi city. Then, in structured interviews, two English teachers provided their opinions on the advantages and disadvantages of integrating Plickers into their classrooms. The findings reveal that both teachers and students believe that using Plickers positively impacts students’ learning. Moreover, the findings encourage teachers to integrate technology-based formative assessments in EFL classrooms. However, there are some drawbacks to using Plickers, such as technological issues. Finally, English teachers are recommended to engage all their students in a daily formative assessment by implementing Plickers in their classes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plickers" title="plickers">plickers</a>, <a href="https://publications.waset.org/abstracts/search?q=formative%20assessment" title=" formative assessment"> formative assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a>, <a href="https://publications.waset.org/abstracts/search?q=EFL%20classroom" title=" EFL classroom"> EFL classroom</a> </p> <a href="https://publications.waset.org/abstracts/144124/the-effectiveness-of-using-plickers-as-a-formative-assessment-tool-in-efl-classrooms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144124.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">33</span> Analysis and Performance of Handover in Universal Mobile Telecommunications System (UMTS) Network Using OPNET Modeller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latif%20Adnane">Latif Adnane</a>, <a href="https://publications.waset.org/abstracts/search?q=Benaatou%20Wafa"> Benaatou Wafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Pla%20Vicent"> Pla Vicent</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Handover is of great significance to achieve seamless connectivity in wireless networks.

People's shopping behavior has greatly changed by the advent of social network. Traditional ticket booking methods are considered as outdated with the advancement in tools and technology. Web based booking framework is an 'absolute necessity to have' for any visit or movement business that is investing heaps of energy noting telephone calls, sending messages or considering employing more staff. In this paper, we propose a process model for online trip reservation for our designed web application. Our proposed system will be highly beneficial and helps in reduction in time and cost for customers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trip" title="trip">trip</a>, <a href="https://publications.waset.org/abstracts/search?q=hotel" title=" hotel"> hotel</a>, <a href="https://publications.waset.org/abstracts/search?q=reservation" title=" reservation"> reservation</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20model" title=" process model"> process model</a>, <a href="https://publications.waset.org/abstracts/search?q=time" title=" time"> time</a>, <a href="https://publications.waset.org/abstracts/search?q=cost" title=" cost"> cost</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20app" title=" web app"> web app</a> </p> <a href="https://publications.waset.org/abstracts/66199/a-process-model-for-online-trip-reservation-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66199.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">214</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> Comparison of Crossover Types to Obtain Optimal Queries Using Adaptive Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wafa%E2%80%99%20Alma%27Aitah">Wafa’ Alma'Aitah</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Almakadmeh"> Khaled Almakadmeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> this study presents an information retrieval system of using genetic algorithm to increase information retrieval efficiency. Using vector space model, information retrieval is based on the similarity measurement between query and documents. Documents with high similarity to query are judge more relevant to the query and should be retrieved first. Using genetic algorithms, each query is represented by a chromosome; these chromosomes are fed into genetic operator process: selection, crossover, and mutation until an optimized query chromosome is obtained for document retrieval. Results show that information retrieval with adaptive crossover probability and single point type crossover and roulette wheel as selection type give the highest recall. The proposed approach is verified using (242) proceedings abstracts collected from the Saudi Arabian national conference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20retrieval" title=" information retrieval"> information retrieval</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20queries" title=" optimal queries"> optimal queries</a>, <a href="https://publications.waset.org/abstracts/search?q=crossover" title=" crossover"> crossover</a> </p> <a href="https://publications.waset.org/abstracts/59109/comparison-of-crossover-types-to-obtain-optimal-queries-using-adaptive-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59109.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">292</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">30</span> Electromagnetic Simulation of Underground Cable Perforation by Nail </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Nour%20El%20Islam%20Ayad">Ahmed Nour El Islam Ayad</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahar%20Rouibah"> Tahar Rouibah</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Krika"> Wafa Krika</a>, <a href="https://publications.waset.org/abstracts/search?q=Houari%20Boudjella"> Houari Boudjella</a>, <a href="https://publications.waset.org/abstracts/search?q=Larab%20Moulay"> Larab Moulay</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Benhamida"> Farid Benhamida</a>, <a href="https://publications.waset.org/abstracts/search?q=Selma%20Benmoussa"> Selma Benmoussa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to evaluate the electromagnetic field of an underground cable of very high voltage perforated by nail.

The paper employs a mixed-methods approach, using both quantitative and qualitative data from surveys, interviews, and online course evaluations. The paper examines three online creative writing courses offered by Oxford University, Stanford University, and Coursera. The paper shows that online creative writing courses can improve the student's writing abilities, enthusiasm, and self-confidence, as well as introduce them to various literary forms and cultures. However, the paper also highlights some challenges and obstacles that the students encounter, such as technical problems, language difficulties, cultural gaps, and lack of feedback and interaction. The paper argues that online creative writing courses can be a useful alternative or addition to conventional classroom instruction, especially during the pandemic. The paper also offers some suggestions for enhancing the quality and effectiveness of online creative writing courses, such as giving more direction, support, and feedback to the students, as well as creating a sense of community and cooperation among them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=online%20creative%20writing%20courses" title="online creative writing courses">online creative writing courses</a>, <a href="https://publications.waset.org/abstracts/search?q=Algerian%20university%20students" title=" Algerian university students"> Algerian university students</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20methods%20approach" title=" mixed methods approach"> mixed methods approach</a>, <a href="https://publications.waset.org/abstracts/search?q=benefits%20and%20chanllenges" title=" benefits and chanllenges"> benefits and chanllenges</a> </p> <a href="https://publications.waset.org/abstracts/168504/online-creative-writing-courses-for-algerian-university-students-a-mixed-methods-study-of-benefits-challenges-and-recommendations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168504.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">104</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">24</span> Eros and Postmodern Nihilism in Don Delillo’s Zero K (2016): A Psychoanalytical Reading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nouioua%20Wafa">Nouioua Wafa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is broadly accepted that the existence of postmodern individuals is distinguished by a predominant presence of skepticism, anxiety and loneliness.

Before introducing the use of multi-media as a supportive teaching tool, a questionnaire was distributed to third year students of a structural design course who were selected as a sample to be surveyed forming a sample of 90 cases. The primary aim of the questionnaire was to identify the students’ learning style and to investigate whether the selected method of teaching could make the teaching and learning process more efficient. Students’ reaction on the use of this method was measured using three key elements indicating that this method is an appropriate teaching method for the nature of the students and the course as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teaching%20method" title="teaching method">teaching method</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture" title=" architecture"> architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20style" title=" learning style"> learning style</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-media" title=" multi-media"> multi-media</a> </p> <a href="https://publications.waset.org/abstracts/39707/an-implementation-of-multi-media-applications-in-teaching-structural-design-to-architectural-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39707.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">437</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> The Valuation of Employees Provident Fund on Long Term Care Cost among Elderly in Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mazlynda%20Md%20Yusuf">Mazlynda Md Yusuf</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafa%27%20Mahadzir"> Wafa' Mahadzir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Yazis%20Ali%20Basah"> Mohamad Yazis Ali Basah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, financing long-term care for elderly people is a crucial issue, either towards the family members or the care institution. Corresponding with the growing number of ageing population in Malaysia, there’s a need of concern on the uncertaintiness of future family care and the need for long-term care services. Moreover, with the increasing cost of living, children feels the urge of needing to work and receive a fixed monthly income that results to sending their elderly parents to care institutions. Currently, in Malaysia, the rates for private nursing homes can amount up to RM 4,000 per month excluding medical treatments and other recurring expenses. These costs are expected to be paid using their Employees Provident Fund (EPF) savings that they accumulate during their working years, especially for those working under private sectors. Hence, this study identifies the adequacy of EPF in funding the cost of long-term care service during old age. This study used a hypothetical simulation model to simulate different scenarios. The findings of this study could be used for individuals to prepare on the importance of planning for retirement, especially with the increasing cost of long-term care services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=long-term%20care%20cost" title="long-term care cost">long-term care cost</a>, <a href="https://publications.waset.org/abstracts/search?q=employees%20provident%20fund%20Malaysia" title=" employees provident fund Malaysia"> employees provident fund Malaysia</a>, <a href="https://publications.waset.org/abstracts/search?q=ageing%20population" title=" ageing population"> ageing population</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysian%20elderly" title=" Malaysian elderly"> Malaysian elderly</a> </p> <a href="https://publications.waset.org/abstracts/74544/the-valuation-of-employees-provident-fund-on-long-term-care-cost-among-elderly-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74544.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">340</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> Metastatic Ovarian Tumor Discovered Accidentally during Cesarean Section in a 34 Year Old Woman: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20E.%20Esheba">Ghada E.

Stomach is the most common primary site. Histopathological features of krukenberg tumors appear as diffuse stromal proliferation, mucus-production, and numerous signet-cells and these tumors spread mostly by lymphatic route. Treatment and prognostic factors are not well established. This study describes a 34 year old female with a unilateral ovarian mass discovered accidentally during cesarean section delivery and it was misdiagnosed as luteoma of pregnancy, but histopathological examination showed a diffuse infiltration of the ovary and omentum by signet ring cells. These findings were not correlated with luteoma of pregnancy or any other types of primary ovarian tumors like surface epithelial tumor, sex cord stromal tumor or germ cell tumor. However, after the analysis of immunohistochemical results (negative CK7, positive CK20 and CDX-2), the finding was the diagnostic of metastatic krukenberg tumor. Two weeks later, the patient was evaluated and a large gastric tumor was found in her stomach and she underwent gastrectomy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CK7" title="CK7">CK7</a>, <a href="https://publications.waset.org/abstracts/search?q=CK20" title=" CK20"> CK20</a>, <a href="https://publications.waset.org/abstracts/search?q=CDX-2" title=" CDX-2"> CDX-2</a>, <a href="https://publications.waset.org/abstracts/search?q=Krukenburg%20tumor" title=" Krukenburg tumor"> Krukenburg tumor</a>, <a href="https://publications.waset.org/abstracts/search?q=metastatic%20ovarian%20tumor" title=" metastatic ovarian tumor"> metastatic ovarian tumor</a> </p> <a href="https://publications.waset.org/abstracts/59354/metastatic-ovarian-tumor-discovered-accidentally-during-cesarean-section-in-a-34-year-old-woman-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59354.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">19</span> Study of the Effect of Sewing on Non Woven Textile Waste at Dry and Composite Scales</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Baccouch">Wafa Baccouch</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Ghith"> Adel Ghith</a>, <a href="https://publications.waset.org/abstracts/search?q=Xavier%20Legrand"> Xavier Legrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Faten%20Fayala"> Faten Fayala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Textile waste recycling has become a necessity considering the augmentation of the amount of waste generated each year and the ecological problems that landfilling and burning can cause. Textile waste can be recycled into many different forms according to its composition and its final utilization. Using this waste as reinforcement to composite panels is a new recycling area that is being studied. Compared to virgin fabrics, recycled ones present the disadvantage of having lower structural characteristics, when they are eco-friendly and with low cost. The objective of this work is transforming textile waste into composite material with good characteristic and low price. In this study, we used sewing as a method to improve the characteristics of the recycled textile waste in order to use it as reinforcement to composite material. Textile non-woven waste was afforded by a local textile recycling industry. Performances tests were evaluated using tensile testing machine and based on the testing direction for both reinforcements and composite panels; machine and transverse direction. Tensile tests were conducted on sewed and non sewed fabrics, and then they were used as reinforcements to composite panels via epoxy resin infusion method. Rule of mixtures is used to predict composite characteristics and then compared to experimental ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20material" title="composite material">composite material</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20resin" title=" epoxy resin"> epoxy resin</a>, <a href="https://publications.waset.org/abstracts/search?q=non%20woven%20waste" title=" non woven waste"> non woven waste</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=sewing" title=" sewing"> sewing</a>, <a href="https://publications.waset.org/abstracts/search?q=textile" title=" textile"> textile</a> </p> <a href="https://publications.waset.org/abstracts/101055/study-of-the-effect-of-sewing-on-non-woven-textile-waste-at-dry-and-composite-scales" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101055.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">586</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> Experimental and Theoretical Analysis of the Electromagnetic Environment in the Vicinity of Two 220Kv Power Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Tourab">Wafa Tourab</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdessalem%20Babouri"> Abdessalem Babouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Nemamcha"> Mohamed Nemamcha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents an experimental and theoretical characterization of electromagnetic environment in the vicinity of EL-HADJAR high voltage substation located in the eastern Algerian within a very high populated zone. There have been analyses on the effects of electromagnetic fields emanating from coupled multi-lines power systems on the health of the workers and people living in proximity of substations. An experimental investigation has been conducted around a circuit of two 220Kv lines running in parallel. The experimental results are validated by a flexible code of calculus developed in the environment Matlab. The implications of the results are discussed and are in very good agreement with the ICNIRP reference levels for occupational and non-occupational exposures. In a case of study, the separation between the two structures “S” is varied to demonstrate its influence on the electric and magnetic charges quantities generated by the circuit of lines proposed. It is found that increasing S decreases the electric and magnetic fields which occur at the center of the structure then reduces the coupling between lines. We concluded that the evaluation of the spacing between the phase conductors is of paramount interest in the preparation of the line’s implantation inside the electrical posts to reduce them radiations in the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20frequency" title="low frequency">low frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20fields" title=" electromagnetic fields"> electromagnetic fields</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20coupling" title=" electromagnetic coupling"> electromagnetic coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20voltage%20power%20lines" title=" high voltage power lines"> high voltage power lines</a> </p> <a href="https://publications.waset.org/abstracts/12019/experimental-and-theoretical-analysis-of-the-electromagnetic-environment-in-the-vicinity-of-two-220kv-power-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12019.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">389</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">17</span> Aptitude of a Lactococcus Strain to Grow on Whey Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Souid%20Wafa">Souid Wafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Boudjenah-Haroun%20Saliha"> Boudjenah-Haroun Saliha</a>, <a href="https://publications.waset.org/abstracts/search?q=Khacef%20Linda"> Khacef Linda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we focused on the valuation of discharges from the dairy industry. Whey is by-product of dairy industry, which is a formidable pollution factor and contains components (lactose, minerals and proteins) with high nutritional value. Whey is an excellent culture medium for microorganisms. The objective of our work is to investigate the ability of a lactic strain (of the genus Lactococcus) to grow in culture media based on whey of cattle and camels and comparing it with that recorded on M17 as indicator medium. In this study we isolated from a local sample of camel milk a lactic strain (S1).the strain had positive Gram shaped, cocci form and catalase (-). The strain has been purified by the method of streaks on M17 medium. Phenotypic identification allows us to classify this strain in the species: Lactococcus lactis subsp. Cremoris. We subsequently tested the ability of this strain to grow in cattle whey medium and camel whey, both media were deproteinized and unsupplemented. The obtained results revealed that: The cattle and camel whey are appropriate media for the growth of the strain Lactococcus lactis subsp cremoris but is more adapted to grow on a medium rich in lactose as the camel whey. In fact, after 48h and at initial pH 6.8 this strain acidified more camel whey (pH 3.99) than cattle whey (pH 4.8). And biomass produced in the camel whey is 1.50g /1 by contributing to the cattle whey which is 1g / l. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cremoris" title="cremoris">cremoris</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20industry" title=" dairy industry"> dairy industry</a>, <a href="https://publications.waset.org/abstracts/search?q=Lactococcus%20lactis%20subsp" title=" Lactococcus lactis subsp"> Lactococcus lactis subsp</a>, <a href="https://publications.waset.org/abstracts/search?q=medium" title=" medium"> medium</a>, <a href="https://publications.waset.org/abstracts/search?q=whey" title=" whey"> whey</a> </p> <a href="https://publications.waset.org/abstracts/40949/aptitude-of-a-lactococcus-strain-to-grow-on-whey-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40949.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">363</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> Facile Hydrothermal Synthesis of Hierarchical NiO/ZnCo₂O₄ Nanocomposite for High-Energy Supercapacitor Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fayssal%20Ynineb">Fayssal Ynineb</a>, <a href="https://publications.waset.org/abstracts/search?q=Toufik%20Hadjersi"> Toufik Hadjersi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatsah%20Moulai"> Fatsah Moulai</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Achour"> Wafa Achour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, tremendous attention has been paid to the rational design and synthesis of core/shell heterostructures for high-performance supercapacitors. In this study, the hierarchical NiO/ZnCo₂O₄ Core-Shell Nanorods Arrays were successfully deposited onto ITO substrate via a two-step hydrothermal and electrodeposition methods. The effect of the thin carbon layer between NiO and ZnCo₂O₄ in this multi-scale hierarchical structure was investigated. The selection of this structure was based on: (i) a high specific area of pseudo-capacitive NiO to maximize specific capacitance; (ii) an effective NiO-electrolyte interface to facilitate fast charging/discharging; and (iii) conducting carbon layer between ZnCo₂O₄ and NiO enhance the electric conductivity which reduces energy loss, and the corrosion protection of ZnCo₂O₄ in alkaline electrolyte. The obtained results indicate that hierarchical NiO/ZnCo₂O₄ present a high specific capacitance of 63 mF.cm⁻² at a current density of 0.05 mA.cm⁻² higher than that of pristine NiO and ZnCo₂O₄ of 6 and 3 mF.cm⁻², respectively. The carbon layer improves the electrical conductivity among NiO and ZnCo₂O₄ in the hierarchical NiO/C/ZnCo₂O₄ electrode. As well, the specific capacitance drastically increased to reach 125 mF.cm⁻². Moreover, this multi-scale hierarchical structure exhibits superior cycling stability with ~ 95.7 % capacitance retention after 65k cycles. These results indicate that the NiO/C/ZnCo₂O₄ nanocomposite material is an outstanding electrode material for supercapacitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NiO%2FC%2FZnCo%E2%82%82O%E2%82%84" title="NiO/C/ZnCo₂O₄">NiO/C/ZnCo₂O₄</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20capacitance" title=" specific capacitance"> specific capacitance</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal" title=" hydrothermal"> hydrothermal</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitors" title=" supercapacitors"> supercapacitors</a> </p> <a href="https://publications.waset.org/abstracts/158685/facile-hydrothermal-synthesis-of-hierarchical-nioznco2o4-nanocomposite-for-high-energy-supercapacitor-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158685.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">99</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> Debate between Breast Milk and Formula Milk in Nutritional Value</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nora%20Alkharji">Nora Alkharji</a>, <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Fallatah"> Wafa Fallatah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: One of the major issues to consider when is deciding on what to feed a baby is the quality of the food itself. Whilst commercially prepared infant formulas are a nutritious alternative to breast milk, and even contain some vitamins and nutrients, most major medical organizations consider breastfeeding the best nutritional option for babies. Choosing whether to breastfeed or formula feed your baby is one of the first decisions expectant parents will make. The American Academy of Pediatrics (AAP) is in agreement with other organizations such as the American Medical Association (AMA), the American Dietetic Association (ADA), and the World Health Organization (WHO) in recommending breastfeeding as the best nutrition for babies and best suited for a baby's digestive system. In addition, breastfeeding helps in the combatting of infections, prevention of allergies, and protection against various chronic conditions. The decision to breastfeed or formula feed one’s baby is a very personal one. However, certain points need to be clarified regarding the nutritional value of breastfeeding versus formula feeding to allow for informed decision-making. Methodology: -A formal debate about whether to breastfeed or formula feed babies as the better choice. -There will be two debaters, both lactation consultants -Arguments will be based on evidence-based medicine -Duration period of debated: 45 min Result: Clarification and heightened awareness of the benefits of breastfeeding. Conclusion: This debate will make the choice between breastfeeding or formula feeding a relatively easy one to make by both health worker and parents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breastmilk" title="breastmilk">breastmilk</a>, <a href="https://publications.waset.org/abstracts/search?q=formula%20milk" title=" formula milk"> formula milk</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional" title=" nutritional"> nutritional</a>, <a href="https://publications.waset.org/abstracts/search?q=comparison" title=" comparison"> comparison</a> </p> <a href="https://publications.waset.org/abstracts/20420/debate-between-breast-milk-and-formula-milk-in-nutritional-value" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20420.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">467</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> Upregulation of CD40/CD40L System in Rheumatic Mitral Stenosis With or Without Atrial Fibrillation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azzam%20H.">Azzam H.</a>, <a href="https://publications.waset.org/abstracts/search?q=Abousamra%20N.%20K."> Abousamra N.

The CD40/CD40 ligand (CD40L) which reflects platelet activation, mediate a central role in thrombotic diseases. However, the role of CD40/CD40L system in rheumatic MS with or without AF remains unclear. Expressions of CD40 on monocytes and CD40L on platelets were determined by whole blood flow cytometry and serum levels of soluble CD40L were measured by enzyme-linked immunosorbent assay in group 1 (19 patients with MS) and group 2 (20 patients with MS and AF) compared to group 3 (10 controls). Patients with groups 1 and 2 had a significant increase in expression of CD40 on monocytes (P1 and P2 = 0.000) and serum levels of sCD40L (P1 = 0.014 and P2 = 0.033, respectively), but nonsignificant increase in expression of CD40L on platelets (P1 = 0.109 and P2 = 0.060, respectively) as compared to controls. There were no significant difference in all the parameters in group 1 compared to group 2. Correlation analysis demonstrated that there was a significant direct relationship between the severity of MS and serum levels of sCD40L (r = -0.469, p = 0.043). In conclusion, rheumatic MS patients with or without AF had upregulation of the CD40/CD40L system as well as elevated sCD40L levels. The levels of sCD40L had a significantly direct relationship with the severity of MS and it was the stenotic mitral valve, not AF, that had a significant impact on platelet activation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CD40" title="CD40">CD40</a>, <a href="https://publications.waset.org/abstracts/search?q=CD40L" title=" CD40L"> CD40L</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20stenosis" title=" mitral stenosis"> mitral stenosis</a>, <a href="https://publications.waset.org/abstracts/search?q=atrial%20fibrillation" title=" atrial fibrillation"> atrial fibrillation</a> </p> <a href="https://publications.waset.org/abstracts/158032/upregulation-of-cd40cd40l-system-in-rheumatic-mitral-stenosis-with-or-without-atrial-fibrillation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158032.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">94</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">13</span> A Multi-Agent Smart E-Market Design at Work for Shariah Compliant Islamic Banking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wafa%20Ghonaim">Wafa Ghonaim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Though quite fast on growth, Islamic financing at large, and its diverse instruments, is a controversial matter among scholars. This is evident from the ongoing debates on its Shariah compliance. Arguments, however, are inciting doubts and concerns among clients about its credibility, which is harming this lucrative sector. The work here investigates, particularly, some issues related to the Tawarruq instrument. The work examines the issues of linking Murabaha and Wakala contracts, the reselling of commodities to same traders, and the transfer of ownerships. The work affirms that a multi-agent smart electronic market design would facilitate Shariah compliance. The smart market exploits the rational decision-making capabilities of autonomous proxy agents that enable the clients, traders, brokers, and the bank buy and sell commodities, and manage transactions and cash flow. The smart electronic market design delivers desirable qualities that terminate the need for Wakala contracts and the reselling of commodities to the same traders. It also resolves the ownership transfer issues by allowing stakeholders to trade independently. The bank administers the smart electronic market and assures reliability of trades, transactions and cash flow. A multi-agent simulation is presented to validate the concept and processes. We anticipate that the multi-agent smart electronic market design would deliver Shariah compliance of personal financing to the aspiration of scholars, banks, traders and potential clients. <p
