This attack required two plaintexts differ from a fixed number and encrypted under same modulus. This paper reports a security reaction of Lucas Based El-Gamal Cryptosystem in the Elliptic Curve group over finite field under GCD attack. Lucas Based El-Gamal Cryptosystem in the Elliptic Curve group over finite field was exposed mathematically to the GCD attack using GCD and Dickson polynomial. The result shows that the cryptanalyst is able to get the plaintext without decryption by using GCD attack. Thus, the study concluded that it is highly perilous when two plaintexts have a slight difference from a fixed number in the same Elliptic curve group over finite field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decryption" title="decryption">decryption</a>, <a href="https://publications.waset.org/abstracts/search?q=encryption" title=" encryption"> encryption</a>, <a href="https://publications.waset.org/abstracts/search?q=elliptic%20curve" title=" elliptic curve"> elliptic curve</a>, <a href="https://publications.waset.org/abstracts/search?q=greater%20common%20divisor" title=" greater common divisor"> greater common divisor</a> </p> <a href="https://publications.waset.org/abstracts/97382/an-attack-on-the-lucas-based-el-gamal-cryptosystem-in-the-elliptic-curve-group-over-finite-field-using-greater-common-divisor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97382.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">256</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">56</span> Fexofenadine Hydrochloride Orodispersisble Tablets: Formulation and in vitro/in vivo Evaluation in Healthy Human Volunteers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soad%20Ali%20Yehia">Soad Ali Yehia</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Shafik%20El-Ridi"> Mohamed Shafik El-Ridi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mina%20Ibrahim%20Tadros"> Mina Ibrahim Tadros</a>, <a href="https://publications.waset.org/abstracts/search?q=Nolwa%20Gamal%20El-Sherif"> Nolwa Gamal El-Sherif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fexofenadine hydrochloride (FXD) is a slightly soluble, bitter-tasting, drug having an oral bioavailability of 35%. The maximum plasma concentration is reached 2.6 hours (Tmax) post-dose. The current work aimed to develop taste-masked FXD orodispersible tablets (ODTs) to increase extent of drug absorption and reduce Tmax. Taste masking was achieved via solid dispersion (SD) with chitosan (CS) or sodium alginate (ALG). FT-IR, DSC and XRD were performed to identify physicochemical interactions and FXD crystallinity. Taste-masked FXD-ODTs were developed via addition of superdisintegrants (crosscarmelose sodium or sodium starch glycolate, 5% and 10%, w/w) or sublimable agents (camphor, menthol or thymol; 10% and 20%, w/w) to FXD-SDs. ODTs were evaluated for weight variation, drug-content, friability, wetting time, disintegration time and drug release. Camphor-based (20%, w/w) FXD-ODT (F12) was optimized (F23) by incorporation of a more hydrophilic lubricant, sodium stearyl fumarate (Pruv®). The topography of the latter formula was examined via scanning electron microscopy (SEM). The in vivo estimation of FXD pharmacokinetics, relative to Allegra® tablets, was evaluated in healthy human volunteers. Based on the gustatory sensation test in healthy volunteers, FXD:CS (1:1) and FXD:ALG (1:0.5) SDs were selected. Taste-masked FXD-ODTs had appropriate physicochemical properties and showed short wetting and disintegration times. Drug release profiles of F23 and phenylalanine-containing Allegra® ODT were similar (f2 = 96) showing a complete release in two minutes. SEM micrographs revealed pores following camphor sublimation. Compared to Allegra® tablets, pharmacokinetic studies in healthy volunteers proved F23 ability to increase extent of FXD absorption (14%) and reduce Tmax to 1.83 h. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fexofenadine%20hydrochloride" title="fexofenadine hydrochloride">fexofenadine hydrochloride</a>, <a href="https://publications.waset.org/abstracts/search?q=taste%20masking" title=" taste masking"> taste masking</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=orodispersible" title=" orodispersible"> orodispersible</a> </p> <a href="https://publications.waset.org/abstracts/4762/fexofenadine-hydrochloride-orodispersisble-tablets-formulation-and-in-vitroin-vivo-evaluation-in-healthy-human-volunteers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4762.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">343</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">55</span> History on the Screen: Nasser and the Biographical Film in Egyptian Cinema</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Khalifah">Omar Khalifah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The emergence of Muhammad Fadel’s 1996 film ‘Nasser 56’ ushered in a new era in Egyptian cinema. Not only was it the first biographical film of late Egyptian president Gamal ‘Abdel Nasser (1918-1970); it also broke a long-accepted taboo against cinematic depiction of modern political leaders. Passionately received by Egyptians and Arabs throughout the world, the success of ‘Nasser 56’ empowered other filmmakers to follow Fadel’s suit. Interestingly, the three biographical films that followed had, completely or partially, a Nasser dimension. In addition to another biographical film of Nasser, Anwar al-Qawadri’s ‘Gamal ‘Abdel Nasser’ (1999); Muhammad Khan’s ‘Ayyam al-Sadat (Days of Sadat)’ (2001), and Sherif Arafa’s ‘Halim (Halim)’ (2006) portray, as the titles clearly suggest, two significant figures whose lives thoroughly intersected with Nasser’s - Nasser’s successor Anwar al-Sadat and the legendary singer Abdel Halim Hafiz. Expectedly, therefore, Nasser himself is abundantly referenced in those films, albeit differently. This paper seeks to examine the ways in which Egyptian filmmakers impersonate Nasser on the screen. Starting with scholarly definitions of the biopic, the paper will first ponder the reasons that have made the biopic an unattractive genre to Egyptian filmmakers. It will then argue that the popularity of Nasser and his wide appeal to the public has transformed the status of the biopic genre in Egyptian cinema. However, the impersonation of Nasser in the four films above proved a daunting mission to filmmakers. As this paper will show, unless he is the main character, the reenactment of Nasser in films will constantly pose dilemmas to filmmakers, a few of which will be discussed in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Zaki" title="Ahmad Zaki">Ahmad Zaki</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-pictures" title=" bio-pictures"> bio-pictures</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptian%20cinema" title=" Egyptian cinema"> Egyptian cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasser" title=" Nasser"> Nasser</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasser%2056" title=" Nasser 56"> Nasser 56</a> </p> <a href="https://publications.waset.org/abstracts/38660/history-on-the-screen-nasser-and-the-biographical-film-in-egyptian-cinema" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38660.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">419</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">54</span> Shape Optimization of Header Pipes in Power Plants for Enhanced Efficiency and Environmental Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Cherif%20Megri">Ahmed Cherif Megri</a>, <a href="https://publications.waset.org/abstracts/search?q=HossamEldin%20ElSherif"> HossamEldin ElSherif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a power plant, the header pipe plays a pivotal role in optimizing the performance of diverse systems by serving as a central conduit for the collection and distribution of steam within the plant. This paper investigates the significance of header pipes within power plant setups, highlighting their critical influence on reliability, efficiency, and the performance of the power plant as a whole. The concept of shape optimization emerges as a crucial factor in power plant design and operation, with the potential to maximize performance while minimizing the use of materials. Shape optimization not only enhances efficiency but also contributes to reducing the environmental footprint of power plant installations. In this paper, we initially developed a methodology designed for optimizing header shapes with the primary goal of reducing the usage of costly new alloy materials and lowering the overall maintenance operation expenses. Secondly, we conducted a case study based on an authentic header sourced from an operational power plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shape%20optimization" title="shape optimization">shape optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=header" title=" header"> header</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant" title=" power plant"> power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=inconel%20alloy" title=" inconel alloy"> inconel alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20optimization" title=" structural optimization"> structural optimization</a> </p> <a href="https://publications.waset.org/abstracts/174024/shape-optimization-of-header-pipes-in-power-plants-for-enhanced-efficiency-and-environmental-sustainability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174024.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">72</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">53</span> Computational Pipeline for Lynch Syndrome Detection: Integrating Alignment, Variant Calling, and Annotations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rofida%20Gamal">Rofida Gamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Mohammed"> Mostafa Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Adel"> Mariam Adel</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Gamal"> Marwa Gamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20kamal"> Marwa kamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayat%20Saber"> Ayat Saber</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Mamdouh"> Maha Mamdouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Emad"> Amira Emad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mai%20Ramadan"> Mai Ramadan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lynch Syndrome is an inherited genetic condition associated with an increased risk of colorectal and other cancers. Detecting Lynch Syndrome in individuals is crucial for early intervention and preventive measures. This study proposes a computational pipeline for Lynch Syndrome detection by integrating alignment, variant calling, and annotation. The pipeline leverages popular tools such as FastQC, Trimmomatic, BWA, bcftools, and ANNOVAR to process the input FASTQ file, perform quality trimming, align reads to the reference genome, call variants, and annotate them. It is believed that the computational pipeline was applied to a dataset of Lynch Syndrome cases, and its performance was evaluated. It is believed that the quality check step ensured the integrity of the sequencing data, while the trimming process is thought to have removed low-quality bases and adaptors. In the alignment step, it is believed that the reads were accurately mapped to the reference genome, and the subsequent variant calling step is believed to have identified potential genetic variants. The annotation step is believed to have provided functional insights into the detected variants, including their effects on known Lynch Syndrome-associated genes. The results obtained from the pipeline revealed Lynch Syndrome-related positions in the genome, providing valuable information for further investigation and clinical decision-making. The pipeline's effectiveness was demonstrated through its ability to streamline the analysis workflow and identify potential genetic markers associated with Lynch Syndrome. It is believed that the computational pipeline presents a comprehensive and efficient approach to Lynch Syndrome detection, contributing to early diagnosis and intervention. The modularity and flexibility of the pipeline are believed to enable customization and adaptation to various datasets and research settings. Further optimization and validation are believed to be necessary to enhance performance and applicability across diverse populations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lynch%20Syndrome" title="Lynch Syndrome">Lynch Syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20pipeline" title=" computational pipeline"> computational pipeline</a>, <a href="https://publications.waset.org/abstracts/search?q=alignment" title=" alignment"> alignment</a>, <a href="https://publications.waset.org/abstracts/search?q=variant%20calling" title=" variant calling"> variant calling</a>, <a href="https://publications.waset.org/abstracts/search?q=annotation" title=" annotation"> annotation</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20markers" title=" genetic markers"> genetic markers</a> </p> <a href="https://publications.waset.org/abstracts/178986/computational-pipeline-for-lynch-syndrome-detection-integrating-alignment-variant-calling-and-annotations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178986.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">52</span> Decision Support System for Solving Multi-Objective Routing Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20El%20Gayar">Ismail El Gayar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ossama%20Ismail"> Ossama Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousri%20El%20Gamal"> Yousri El Gamal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presented a technique to solve one of the transportation problems that faces us in real life which is the Bus Scheduling Problem.

This dichotomy however was challenged by many anticolonial leaders and intellectuals seeking to advance counter-hegemonic narratives that treat the Sahara as a bridge facilitating a long history of exchange, collaboration, and fusion between different civilizations on the continent. This paper reexamines the discourses governing the geographic distinction between North Africa and Sub-Saharan Africa. It argues that demarcating the African continent along the lines of the Sahara is part-and-parcel of a Euro-centric spatial imaginary that has served to enshrine a racialized global hierarchy of power. By drawing on Edward Said’s concept of ‘imagined geography’ and Charles Mill’s notion of “the racial contract”, it demonstrates how spatial boundaries often coincide with racial epistemologies to reinforce certain geopolitical imaginaries, whilst silencing others. It further draws on the works of two notable post-colonial figures - Gamal Abdel Nasser and Leopold Senghor - to explore alternative spatial imaginaries while highlighting some of the tensions embedded in advancing a trans-Saharan political project. Firstly, it deconstructs some of the normative claims used to justify the distinction between North and “sub-Saharan” Africa across political, literary and disciplinary boundaries. Secondly, it draws parallels between Said’s and Mills’ work to demonstrate how geographical boundaries and demarcations have been constructed to create racialized subjects and reinforce a hierarchy of color that favors European standpoints and epistemologies. Third, it draw on Leopard Senghor’s The Foundations of Africanité and Gamal Abdel Nasser’s The Philosophy of the Egyptian Revolution to examine some of the competing strands of unity that emerged out of the Saharan discourse. In these texts, one can identify a number of convergences and divergences in how post-colonial African elites attempts to reclaim and rearticulate the function of the Sahara along different epistemic, political and cultural premises. It concludes with reflections on some of the policy challenges that emerge from reinforcing the Saharan divide, particularly in the realm of peace and security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=regional%20integration" title="regional integration">regional integration</a>, <a href="https://publications.waset.org/abstracts/search?q=politics%20of%20knowledge%20production" title=" politics of knowledge production"> politics of knowledge production</a>, <a href="https://publications.waset.org/abstracts/search?q=arab-african%20relations" title=" arab-african relations"> arab-african relations</a>, <a href="https://publications.waset.org/abstracts/search?q=african%20solutions%20to%20african%20problems" title=" african solutions to african problems"> african solutions to african problems</a> </p> <a href="https://publications.waset.org/abstracts/157241/reclaiming-the-sahara-as-a-bridge-to-afro-arab-solidarity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157241.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">86</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">50</span> A Simulation Modeling Approach for Optimization of Storage Space Allocation in Container Terminal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gamal%20Abd%20El-Nasser%20A.%20Said">Gamal Abd El-Nasser A.

For this goal we have used BEopt software (building energy optimization) that provides capabilities for estimating residential building design and thermal analysis. The most area of the house that is exposed to the sunlight’s is the roof leading to heat gain. Therefore, house cooling consumes high energy. The cooling energy consumption is three times the heating energy consumption. In order to maintain comfortable indoor conditions in a low-energy house, the entire building envelope needs to be perfectly insulated and prevented from air leakages. Insulated roof is selected to reduce cooling demand, and the paper presents details and BEopt simulation results. Designed house needs 12.02mmbtus/year. Furthermore, the modeling indicates that the designed house is close to achieving the Passive standard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20house%20design" title="concrete house design">concrete house design</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20analysis" title=" thermal analysis"> thermal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20climate" title=" hot climate"> hot climate</a>, <a href="https://publications.waset.org/abstracts/search?q=BEopt%20software" title=" BEopt software"> BEopt software</a> </p> <a href="https://publications.waset.org/abstracts/49598/design-and-thermal-analysis-of-a-concrete-house-in-libya-using-beopt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49598.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">411</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">41</span> The Effect of Artificial Intelligence on Construction Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shady%20Gamal%20Aziz%20Shehata">Shady Gamal Aziz Shehata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Difficulty in defining construction quality arises due to perception based on the nature and requirements of the market, the different partners themselves and the results they want. Quantitative research was used in this constructivist research. A case-based study was conducted to assess the structures of positive attitudes and expectations in the context of quality improvement. A survey based on expert opinions was analyzed among construction organizations/companies operating in the construction industry in Pakistan. The financial strength, management structure and construction experience of the construction companies formed the basis of their selection. A good concept is visible at the project level and is seen as the most valuable part of the construction project. Each quality improvement technique was expected to increase the user's profits by improving the efficiency of the construction project. The Survey is useful for construction professionals to evaluate current construction concepts and expectations for the application of quality improvement techniques in construction projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation%20analysis" title="correlation analysis">correlation analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20construction%20tools" title=" lean construction tools"> lean construction tools</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20construction" title=" lean construction"> lean construction</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20regression%20analysis" title=" logistic regression analysis"> logistic regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20construction%20quality" title=" safety construction quality"> safety construction quality</a>, <a href="https://publications.waset.org/abstracts/search?q=expectation" title=" expectation"> expectation</a>, <a href="https://publications.waset.org/abstracts/search?q=improvement" title=" improvement"> improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a> </p> <a href="https://publications.waset.org/abstracts/185149/the-effect-of-artificial-intelligence-on-construction-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185149.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">59</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">40</span> Modelling and Technical Assessment of Multi-Motor for Electric Vehicle Drivetrains by Using Electric Differential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdel-Monem">Mohamed Abdel-Monem</a>, <a href="https://publications.waset.org/abstracts/search?q=Gamal%20Sowilam"> Gamal Sowilam</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Hegazy"> Omar Hegazy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a technical assessment of an electric vehicle with two independent rear-wheel motor and an improved traction control system. The electric differential and the control strategy have been implemented to assure that in a straight trajectory, the two rear-wheels run exactly at the same speed, considering the same/different road conditions under the left and right side of the wheels. In case of turning to right/left, the difference between the two rear-wheels speeds assures a vehicle trajectory without sliding, thanks to a harmony between the electric differential and the control strategy. The present article demonstrates a complete model and analysis of a traction control system, considering four different traction scenarios, for two independent rear-wheels motors for electric vehicles. Furthermore, the vehicle model, including wheel dynamics, load forces, electric differential, and control strategy, is designed and verified by using MATLAB/Simulink environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicle" title="electric vehicle">electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20saving" title=" energy saving"> energy saving</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-motor" title=" multi-motor"> multi-motor</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20differential" title=" electric differential"> electric differential</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20and%20control" title=" simulation and control"> simulation and control</a> </p> <a href="https://publications.waset.org/abstracts/90576/modelling-and-technical-assessment-of-multi-motor-for-electric-vehicle-drivetrains-by-using-electric-differential" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90576.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">351</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Performance of Modified Wedge Anchorage System for Pre-Stressed FRP Bars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Othman%20S.%20Alsheraida">Othman S.

However, the main obstacle for their wide use in the pre-stressed concrete application is the anchorage system. Due to the weakness of FRP in the transverse direction, the pre-stressing capacity of FRP bars is limited. This paper investigates the modification of the conventional wedge anchorage system to be used for stressing of FRP bars in pre-stressed applications. Epoxy adhesive material with glass FRP (GFRP) bars and conventional steel wedge were used in this paper. The GFRP bars are encased with epoxy at the anchor zone and the wedge system was used in the pull-out test. The results showed a loading capacity of 47.6 kN which is 69% of the bar ultimate capacity. Additionally, nylon wedge was made with the same dimensions of the steel wedge and tested for GFRP bars without epoxy layer. The nylon wedge showed a loading capacity of 19.7 kN which is only 28.5% of the ultimate bar capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anchorage" title="anchorage">anchorage</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy" title=" epoxy"> epoxy</a>, <a href="https://publications.waset.org/abstracts/search?q=frp" title=" frp"> frp</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-stressed" title=" pre-stressed"> pre-stressed</a> </p> <a href="https://publications.waset.org/abstracts/31388/performance-of-modified-wedge-anchorage-system-for-pre-stressed-frp-bars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31388.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">296</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> Solar Seawater Desalination Still with Seawater Preheater Using Efficient Heat Transfer Oil: Numerical Investigation and Data Verification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20N.%20Shmroukh">Ahmed N.

This solar desalination unit with proposed auxiliary device as seawater preheating system using petrol based textherm oil was used to produce pure fresh water from seawater. The effective evaporation area of basin is about 1 m<sup>2</sup>. The unit was tested in two main operation modes which are normal and with seawater preheating system. The results showed that, there is good agreement between the theoretical data and the experimental data; this means that the numerical model can be accurately dependable for predicting the proposed solar still performance and design parameters. The results also showed that the fresh water productivity of the solar still in the modified preheating case which is higher than normal case, leads to an increase in productivity of 42%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=improving%20productivity" title="improving productivity">improving productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=seawater%20desalination" title=" seawater desalination"> seawater desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20stills" title=" solar stills"> solar stills</a>, <a href="https://publications.waset.org/abstracts/search?q=theoretical%20model" title=" theoretical model"> theoretical model</a> </p> <a href="https://publications.waset.org/abstracts/101175/solar-seawater-desalination-still-with-seawater-preheater-using-efficient-heat-transfer-oil-numerical-investigation-and-data-verification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101175.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">136</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> Evaluation of Scenedesmus obliquus Carotenoids as Food Colorants, and Antioxidant Activity in Functional Cakes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20H.%20Abd%20El%20Baky">Hanaa H.

In this work we prepared functional pre-biotic cakes to increase general mental health. Functional cakes were formulated by adding algal caroteinods at 2 and 4 mg/100g to flower and the cakes were storage for 20 days. Oxidative stability of both function cakes products were examined during storage periods by DPPH and TBA assays, and the results revealed that both values in function food products were significantly much low than that in untreated food products. Data of sensory evaluation revealed that treated biscuit and cakes with algae or algae extracts were significantly acceptable as control for main sensory characteristics (colour, odour/aroma, flavour, texture, the global appreciation, and overall acceptability). Thus, it could be concluded that functional biscuits and cakes (very popular and well balanced nutritional food) had good sensory and nutritional profiles and can be developed as new niche food market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Scenedesmus%20obliquus" title="Scenedesmus obliquus">Scenedesmus obliquus</a>, <a href="https://publications.waset.org/abstracts/search?q=carotenoids" title=" carotenoids"> carotenoids</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20cakes%20antioxidant" title=" functional cakes antioxidant"> functional cakes antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20profiles" title=" nutritional profiles"> nutritional profiles</a> </p> <a href="https://publications.waset.org/abstracts/16287/evaluation-of-scenedesmus-obliquus-carotenoids-as-food-colorants-and-antioxidant-activity-in-functional-cakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16287.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Cytotoxic Metabolites from Tagetes minuta L.

Their structures were established based on physical, chemical, and spectral data [Ultraviolet (UV), Proton ¹H, Carbon thirteen ¹³C, and Heteronuclear Multiple Bond Correlation (HMBC) NMR], as well as Electrospray Ionization Mass Spectroscopy (ESIMS) and comparison with literature data. Their cytotoxic activity was assessed towards human liver hepatocellular carcinoma (HepG2), human breast cancer (MCF-7), and human colon cancer (HCT116) cancer cell lines using sulphorhodamine B (SRB) assay. It is noteworthy that compound 1 demonstrated a significant cytotoxic potential towards HepG2, MCF7, and HCT116 cells with IC₅₀s ranging from 2.74 to 7.01 μM, compared to doxorubicin (IC₅₀ 0.18, 0.60, and 0.20 μM, respectively), whereas compounds 2, 4, and 5 showed moderate cytotoxic potential with IC50s ranging from 11.71 to 35.64 μM.

For the satellite geodesy, it is very important to determine the optimal length of orbital arc along which laser measurements are to be carried out. It is clear that for the dynamical methods long arcs (one month or more) are to be used. According to which more errors of modeling of different physical forces such as earth's gravitational field, air drag, solar radiation pressure, and others that may influence the accuracy of the estimation of the satellites position, at the same time the measured errors con be almost completely excluded and high stability in determination of relative coordinate system can be achieved. It is possible to diminish the influence of the errors of modeling by using short-arcs of the satellite orbit (several revolutions or days), but the station's coordinates estimated by different arcs con differ from each other by a larger quantity than statistical zero. Under the semidynamical ‘short arc’ method one or several passes of the satellite in one of simultaneous visibility from both ends of the chord is known and the estimated parameter in this case is the length of the chord. The comparison of the same baselines calculated with long and short arcs methods shows a good agreement and even speaks in favor of the last one. In this paper the Short Arc technique has been explained and 3 baselines have been determined using the ‘short arc’ method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=baselines" title="baselines">baselines</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20arc" title=" short arc"> short arc</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamical" title=" dynamical"> dynamical</a>, <a href="https://publications.waset.org/abstracts/search?q=gravitational%20field" title=" gravitational field"> gravitational field</a> </p> <a href="https://publications.waset.org/abstracts/35298/short-arc-technique-for-baselines-determinations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35298.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">463</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Biochar as a Strong Adsorbent for Multiple-Metal Removal from Contaminated Water </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20H.%20El-Gamal">Eman H.

In this study, different types of biochar (rice straw 'RSB', corn cob 'CCB', and Jatropha shell 'JSB' were used to evaluate the adsorption capacity of heavy metals removal from multiple-metal solutions (Cu, Mn, Zn, and Cd). Kinetics modeling has been examined to illustrate potential adsorption mechanisms. The results showed that the potential removal of metal is dependent on the metal and biochar types. The adsorption capacity of the biochars followed the order: RSB > JSB > CCB. In general, RSB and JSB biochars presented high potential removal of heavy metals from polluted water, which was higher than 90 and 80% after 2 hrs of contact time for all metals, respectively. According to the kinetics data, the pseudo-second-order model was agreed strongly with Cu, Mn, Zn, and Cd adsorption onto the biochars (R2 ≥ 0.97), indicating the dominance of specific adsorption process, i.e., chemisorption. In conclusion, this study revealed that RSB and JSB biochar have the potential to be a strong adsorbent for multiple-metal removal from wastewater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=biochar" title=" biochar"> biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=chemisorption" title=" chemisorption"> chemisorption</a>, <a href="https://publications.waset.org/abstracts/search?q=polluted%20water" title=" polluted water"> polluted water</a> </p> <a href="https://publications.waset.org/abstracts/119198/biochar-as-a-strong-adsorbent-for-multiple-metal-removal-from-contaminated-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119198.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">150</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> Ideological Passing: A Study of Tawfiq Al-Hakim’s The River of Madness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Khamis%20Ragab%20Aman">Yasser Khamis Ragab Aman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tawfiq Al-Hakim (1898-1987) celebrated the 1919 Revolution by writing The Return of The Spirit published in 1933, a novel which portrayed national awakening and illustrated the cult of a nationalist leader, such as Saad Zaghloul so much that it influenced Egypt’s first president Gamal Abdel Nasser. However, in 1974, and because of an excruciating sense of disappointment, Al-Hakim wrote The Return of Consciousness. Between losing and regaining consciousness, Al-Hakim wrote The River of Madness, a short play published in 1937. It portrays an old kingdom established in a distant place where there is a conflict between the King and his minister, who have not drunk from the river of madness, on the one hand, and the inhabitants of the kingdom who thought that the King and the minister have gone mad because they refused to drink from the river. (Each party doubted the sanity of the other). In fact, the King and the minister differ in their political stance from the rest of the people. By philosophical reasoning, the minister convinces the King that it is safer to go mad with the majority than to be treated as an unwanted minority. It is believed that in The River of Madness, Al-Hakim deftly portrays an example of ideological passing as an alternative solution that can save the country from the woes of the aftermath of revolution and civil war. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ideological%20passing" title="ideological passing">ideological passing</a>, <a href="https://publications.waset.org/abstracts/search?q=Al%20Hakim" title=" Al Hakim"> Al Hakim</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20River%20of%20Madness" title=" The River of Madness"> The River of Madness</a>, <a href="https://publications.waset.org/abstracts/search?q=Arabic%20literature" title=" Arabic literature"> Arabic literature</a> </p> <a href="https://publications.waset.org/abstracts/172709/ideological-passing-a-study-of-tawfiq-al-hakims-the-river-of-madness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172709.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">136</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> Evaluation of Gasoline Engine Piston with Various Coating Materials Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nouby%20Ghazaly">Nouby Ghazaly</a>, <a href="https://publications.waset.org/abstracts/search?q=Gamal%20Fouad"> Gamal Fouad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Abd-El-Tawwab"> Ali Abd-El-Tawwab</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20A.%20Abd%20El-Gwwad"> K.

After that, investigation of four coating materials namely, yttria-stabilized zirconia, magnesia-stabilized zirconia, alumina, and mullite are studied for each piston materials. Next, influence of various thickness coating layers on the structure stresses of the top surfaces is examined. Comparison between simulated results for aluminum, steel, and cast-iron materials is reported. Moreover, the influences of different coating thickness on the Von Mises stresses of four coating materials are investigated. From the simulation results, it can report that the maximum Von Mises stresses and deformations for the piston materials are decreasing with increasing the coating thickness for magnesia-stabilized zirconia, yttria-stabilized zirconia, mullite and alumina coated materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=structure%20analysis" title="structure analysis">structure analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum%20piston" title=" aluminum piston"> aluminum piston</a>, <a href="https://publications.waset.org/abstracts/search?q=MgZrO%E2%82%83" title=" MgZrO₃"> MgZrO₃</a>, <a href="https://publications.waset.org/abstracts/search?q=YTZ" title=" YTZ"> YTZ</a>, <a href="https://publications.waset.org/abstracts/search?q=mullite%20and%20alumina" title=" mullite and alumina"> mullite and alumina</a> </p> <a href="https://publications.waset.org/abstracts/106028/evaluation-of-gasoline-engine-piston-with-various-coating-materials-using-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106028.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">151</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> A phytochemical and Biological Study of Viscum schemperi Engl.

Their structures were established based on physical, chemical, and spectral data. Anti-inflammatory and anti-apoptotic activities of oleanolic acid in a mouse model of acute hepatorenal damage were assessed. This study showed the efficacy of oleanolic acid to counteract thioacetamide-induced hepatic and kidney injury in mice through the reduction of hepatocyte oxidative damage, suppression of inflammation, and apoptosis. More importantly, oleanolic acid suppressed thioacetamide-induced hepatic and kidney injury by inhibiting NF-κB/TNF-α-mediated inflammation/apoptosis and enhancing SIRT1/Nrf2/Heme-oxygenase signalling pathway. These promising pharmacological activities suggest the potential use of oleanolic acid against hepatorenal damage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oleanolic%20acid" title="oleanolic acid">oleanolic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=viscum%20schimperi" title=" viscum schimperi"> viscum schimperi</a>, <a href="https://publications.waset.org/abstracts/search?q=thioacetamide" title=" thioacetamide"> thioacetamide</a>, <a href="https://publications.waset.org/abstracts/search?q=SIRT1%2FNrf2%2FNF-%CE%BAB" title=" SIRT1/Nrf2/NF-κB"> SIRT1/Nrf2/NF-κB</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatorenal%20damage" title=" hepatorenal damage"> hepatorenal damage</a> </p> <a href="https://publications.waset.org/abstracts/169183/a-phytochemical-and-biological-study-of-viscum-schemperi-engl-growing-in-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169183.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">30</span> Recommender System Based on Mining Graph Databases for Data-Intensive Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Gamal">Mostafa Gamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoda%20K.%20Mohamed"> Hoda K.

The evolution of online-based multimedia data poses new challenges in storing and querying large amounts of data for online recommender systems. Graph data models have been shown to be more efficient than relational data models for processing complex data. This paper will explain the key differences between graph and relational databases, their strengths and weaknesses, and why using graph databases is the best technology for building a realtime recommendation system. Also, The paper will discuss several similarity metrics algorithms that can be used to compute a similarity score of pairs of nodes based on their neighbourhoods or their properties. Finally, the paper will discover how NLP strategies offer the premise to improve the accuracy and coverage of realtime recommendations by extracting the information from the stored unstructured knowledge, which makes up the bulk of the world’s data to enrich the graph database with this information. As the size and number of data items are increasing rapidly, the proposed system should meet current and future needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graph%20databases" title="graph databases">graph databases</a>, <a href="https://publications.waset.org/abstracts/search?q=NLP" title=" NLP"> NLP</a>, <a href="https://publications.waset.org/abstracts/search?q=recommendation%20systems" title=" recommendation systems"> recommendation systems</a>, <a href="https://publications.waset.org/abstracts/search?q=similarity%20metrics" title=" similarity metrics"> similarity metrics</a> </p> <a href="https://publications.waset.org/abstracts/163018/recommender-system-based-on-mining-graph-databases-for-data-intensive-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163018.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">29</span> A Theoretical Model for a Humidification Dehumidification (HD) Solar Desalination Unit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasser%20El-Henawy">Yasser El-Henawy</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Abd%20El-Kader"> M.

A humidification-dehumidification (HD) solar desalination unit has been designed to provide fresh water for population in remote arid areas. It consists of solar water collector and air collector; to provide the hot water and air to the desalination chamber. The desalination chamber is divided into humidification and dehumidification towers. The circulation of air between the two towers is maintained by the forced convection. A mathematical model has been formulated, in which the thermodynamic relations were used to study the flow, heat and mass transfer inside the humidifier and dehumidifier. The present technique is performed in order to increase the unit performance. Heat and mass balance has been done and a set of governing equations has been solved using the finite difference technique. The unit productivity has been calculated along the working day during the summer and winter sessions and has compared with the available experimental results. The average accumulative productivity of the system in winter has been ranged between 2.5 to 4 kg/m2.day, while the average summer productivity has been found between 8 to 12 kg/m2 day. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20desalination" title="solar desalination">solar desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20collector" title=" solar collector"> solar collector</a>, <a href="https://publications.waset.org/abstracts/search?q=humidification%20and%20dehumidification" title=" humidification and dehumidification"> humidification and dehumidification</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference" title=" finite difference"> finite difference</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20productivity" title=" water productivity"> water productivity</a> </p> <a href="https://publications.waset.org/abstracts/31494/a-theoretical-model-for-a-humidification-dehumidification-hd-solar-desalination-unit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31494.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">412</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> Health Satisfaction and Family Impact of Parents of Children with Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ekhlas%20Al%20Gamal">Ekhlas Al Gamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tony%20Long"> Tony Long</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impact on the parents of caring for a child with cancer was intense and wide-ranging. A high level of distress and low level or resilience remains during treatment. Even completion of treatment can be a time of increased anxiety and stress for parents particularly with worries about recurrence or relapse. The purpose of this study to examine the associations between parental satisfactions with healthcare provided for their child and the impact of being a caregiver for a child with cancer. Methodology: A descriptive, correlational and cross-sectional design was employed using data from Arabic versions of self-report questionnaires which were administered to 113 parents with children with cancer in Jordan during 2015. Findings: the result indicated that Family relationship functioning was ranked as the highest (better functioning) domain while daily activities were ranked as the lowest (poorer functioning) domain. Parents were generally satisfied with the health care provided, but their emotional needs were not met adequately. Parents with better social functioning were more satisfied in all areas of healthcare satisfaction other than emotional needs and communication. Parents who had a child with more emotional and behavioural problems were more likely to experience a negative impact on the family and a poor level of family functioning. Conclusion and Significance: Nurses and other health care providers should emphasis on family centred approach rather than child centred approach. <p class="card-text"><strong>Keywords:</strong> <a
