Lawrence's 'Sons and Lovers'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaich%20Hamza%20Walid">Chaich Hamza Walid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary goal of this paper is to question the situation of men’s place in D.H Lawrence’s Sons and Lovers. Our question is what is the role of each man in the novel? And how a mother’s possessiveness had changed the life of all men in the family? David Herbert Lawrence was an important and controversial English writer of the 20th century. He wrote many great works, one of his most popular novels, Sons and Loves, is an autobiographical account of his youth. This novel is about the life of the Morels. The author develops the story by portraying the relationships between many characters, especially the male ones we focus on. ‘Sons and Lovers’ seems to be written especially to women, all what Lawrence wrote is about women but when we go deeper, we see that Lawrence was also interested in men. This work will approach the question in two ways. The first chapter will deal with men’s place in D.H Lawrence’s Sons and Lovers, more exactly with Paul and his father Walter Morel, and with Baxter Dawes. We will focus on each man’s behavior with one another. In the second chapter, we will analyze possessiveness, that is to say, the desire of holding or having someone as one’s own or under one’s control. We will try to prove this view from the spiritual and symbolic possession of different relationships. Our study will be through an intensive psychological analysis of a wife’s possessiveness to her husband, and a mother’s possessiveness to her son’s; William and Paul. The conclusion will review all the important aspects of this analysis. It is very important to know about men’s relationships in D.H Lawrence’s Sons and Lovers this will give us another vision of the novel, and where we can situate Paul’s true relationships, that is to say, his relationships with his father and the other men in the novel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=language" title="language">language</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=English" title=" English"> English</a>, <a href="https://publications.waset.org/abstracts/search?q=civilisation" title=" civilisation"> civilisation</a> </p> <a href="https://publications.waset.org/abstracts/43722/mens-relationships-in-d-h-lawrences-sons-and-lovers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43722.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">461</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">71</span> Comparative Studies of the Effects of Microstructures on the Corrosion Behavior of Micro-Alloyed Steels in Unbuffered 3.5 Wt% NaCl Saturated with CO2</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lawrence%20I.%20Onyeji">Lawrence I.

Bijan Kermani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corrosion problem which exists in every stage of oil and gas production has been a great challenge to the operators in the industry. The conventional carbon steel with all its inherent advantages has been adjudged susceptible to the aggressive corrosion environment of oilfield. This has aroused increased interest in the use of micro alloyed steels for oil and gas production and transportation. The corrosion behavior of three commercially supplied micro alloyed steels designated as A, B, and C have been investigated with API 5L X65 as reference samples. Electrochemical corrosion tests were conducted in an unbuffered 3.5 wt% NaCl solution saturated with CO<sub>2</sub> at 30 <sup>0</sup>C for 24 hours. Pre-corrosion analyses revealed that samples A, B and X65 consist of ferrite-pearlite microstructures but with different grain sizes, shapes and distribution whereas sample C has bainitic microstructure with dispersed acicular ferrites. The results of the electrochemical corrosion tests showed that within the experimental conditions, the corrosion rate of the samples can be ranked as CR<sub>(A)</sub>< CR<sub>(X65)</sub>< CR<sub>(B)</sub>< CR<sub>(C)</sub>. These results are attributed to difference in microstructures of the samples as depicted by ASTM grain size number in accordance with ASTM E112-12 Standard and ferrite-pearlite volume fractions determined by ImageJ Fiji grain size analysis software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20corrosion" title="carbon dioxide corrosion">carbon dioxide corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20behaviour" title=" corrosion behaviour"> corrosion behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-alloyed%20steel" title=" micro-alloyed steel"> micro-alloyed steel</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructures" title=" microstructures"> microstructures</a> </p> <a href="https://publications.waset.org/abstracts/57843/comparative-studies-of-the-effects-of-microstructures-on-the-corrosion-behavior-of-micro-alloyed-steels-in-unbuffered-35-wt-nacl-saturated-with-co2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57843.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">350</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">70</span> Foreignization and Domestication in the West and the East: A Comparative Study of Lawrence Venuti and Lu Xun’s Translation Theories</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xijinyan%20Chen">Xijinyan Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of translation is one of the fields that have been dominated by the voices from the west. Both Lawrence Venuti and Lu Xun advocate a translation strategy of 'foreignization' sixty years apart from each other: the former in 1995 and the latter in 1935. And yet only Venuti’s idea has become one of the best-accepted ones in the translation paradigm, while Lu’s was rarely mentioned or even unknown to some. The paper attempts to provide a comprehensive comparative study of the theories proposed by the American translation scholar and the Chinese writer/translator scholar and re-examine the alleged Eurocentrism in translation studies. The paper first compares and contrasts the backgrounds, developments and main ideas of Venuti and Lu’s translation theories and then discusses the possible reasons behind the distinct receptions. The paper argues that in addition to lacking a systematic development, Lu’s idea seems to be limited to a certain Chinese political and cultural context and thus fail to reach out to a larger group of audiences. By introducing Lu’s idea and comparing it with Venuti’s, the paper aims at drawing some attention and interests to non-western voices in the translation field, so as to enrich and inspire the current translation scholarship. It is hoped that the study demonstrates the significance of establishing a field of comparative translation theories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comparative%20translation%20theories" title="comparative translation theories">comparative translation theories</a>, <a href="https://publications.waset.org/abstracts/search?q=eurocentrism" title=" eurocentrism"> eurocentrism</a>, <a href="https://publications.waset.org/abstracts/search?q=domestication%20and%20foreignization" title=" domestication and foreignization"> domestication and foreignization</a>, <a href="https://publications.waset.org/abstracts/search?q=Lawrence%20Venuti" title=" Lawrence Venuti"> Lawrence Venuti</a>, <a href="https://publications.waset.org/abstracts/search?q=Lu%20Xun" title=" Lu Xun"> Lu Xun</a> </p> <a href="https://publications.waset.org/abstracts/110374/foreignization-and-domestication-in-the-west-and-the-east-a-comparative-study-of-lawrence-venuti-and-lu-xuns-translation-theories" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110374.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">253</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">69</span> Landslide Susceptibility Analysis in the St. Lawrence Lowlands Using High Resolution Data and Failure Plane Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Potoczny">Kevin Potoczny</a>, <a href="https://publications.waset.org/abstracts/search?q=Katsuichiro%20Goda"> Katsuichiro Goda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The St. Lawrence lowlands extend from Ottawa to Quebec City and are known for large deposits of sensitive Leda clay. Leda clay deposits are responsible for many large landslides, such as the 1993 Lemieux and 2010 St. Jude (4 fatalities) landslides. Due to the large extent and sensitivity of Leda clay, regional hazard analysis for landslides is an important tool in risk management. A 2018 regional study by Farzam et al. on the susceptibility of Leda clay slopes to landslide hazard uses 1 arc second topographical data. A qualitative method known as Hazus is used to estimate susceptibility by checking for various criteria in a location and determine a susceptibility rating on a scale of 0 (no susceptibility) to 10 (very high susceptibility). These criteria are slope angle, geological group, soil wetness, and distance from waterbodies. Given the flat nature of St. Lawrence lowlands, the current assessment fails to capture local slopes, such as the St. Jude site. Additionally, the data did not allow one to analyze failure planes accurately. This study majorly improves the analysis performed by Farzam et al. in two aspects. First, regional assessment with high resolution data allows for identification of local locations that may have been previously identified as low susceptibility. This then provides the opportunity to conduct a more refined analysis on the failure plane of the slope. Slopes derived from 1 arc second data are relatively gentle (0-10 degrees) across the region; however, the 1- and 2-meter resolution 2022 HRDEM provided by NRCAN shows that short, steep slopes are present. At a regional level, 1 arc second data can underestimate the susceptibility of short, steep slopes, which can be dangerous as Leda clay landslides behave retrogressively and travel upwards into flatter terrain. At the location of the St. Jude landslide, slope differences are significant. 1 arc second data shows a maximum slope of 12.80 degrees and a mean slope of 4.72 degrees, while the HRDEM data shows a maximum slope of 56.67 degrees and a mean slope of 10.72 degrees. This equates to a difference of three susceptibility levels when the soil is dry and one susceptibility level when wet. The use of GIS software is used to create a regional susceptibility map across the St. Lawrence lowlands at 1- and 2-meter resolutions. Failure planes are necessary to differentiate between small and large landslides, which have so far been ignored in regional analysis. Leda clay failures can only retrogress as far as their failure planes, so the regional analysis must be able to transition smoothly into a more robust local analysis. It is expected that slopes within the region, once previously assessed at low susceptibility scores, contain local areas of high susceptibility. The goal is to create opportunities for local failure plane analysis to be undertaken, which has not been possible before. Due to the low resolution of previous regional analyses, any slope near a waterbody could be considered hazardous. However, high-resolution regional analysis would allow for more precise determination of hazard sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hazus" title="hazus">hazus</a>, <a href="https://publications.waset.org/abstracts/search?q=high-resolution%20DEM" title=" high-resolution DEM"> high-resolution DEM</a>, <a href="https://publications.waset.org/abstracts/search?q=leda%20clay" title=" leda clay"> leda clay</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20analysis" title=" regional analysis"> regional analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=susceptibility" title=" susceptibility"> susceptibility</a> </p> <a href="https://publications.waset.org/abstracts/167848/landslide-susceptibility-analysis-in-the-st-lawrence-lowlands-using-high-resolution-data-and-failure-plane-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167848.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">77</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">68</span> Prototyping the Problem Oriented Medical Record for Connected Health Based on TypeGraphQL</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabah%20Mohammed">Sabah Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinan%20Fiaidhi"> Jinan Fiaidhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Darien%20Sawyer"> Darien Sawyer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data integration of health through connected services can save lives in the event of a medical emergency or provide efficient and effective interventions for the benefit of the patients through the integration of bedside and bench side clinical research. Such integration will support all wind of change in healthcare by being predictive, pre-emptive, personalized, problem-oriented and participatory. Prototyping a healthcare system that enables data integration has been a big challenge for healthcare for a long time. However, an innovative solution started to emerge by focusing on problem lists where everything can connect the problem list forming a growing graph. This notion was introduced by Dr. Lawrence Weed in early 70’s, but the enabling technologies weren’t mature enough to provide a successful implementation prototype. In this article, we are describing our efforts in prototyping Dr. Lawrence Weed's problem-oriented medical record (POMR) and his patient case schema (SOAP) to shape a prototype for connected health. For this, we are using the TypeGraphQL API and our enterprise-based QL4POMR to describe a Web-Based gateway for healthcare services connectivity. Our prototype has reported success in connecting to the HL7 FHIR medical record and the OpenTarget biomedical repositories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=connected%20health" title="connected health">connected health</a>, <a href="https://publications.waset.org/abstracts/search?q=problem-oriented%20healthcare%20record" title=" problem-oriented healthcare record"> problem-oriented healthcare record</a>, <a href="https://publications.waset.org/abstracts/search?q=SOAP" title=" SOAP"> SOAP</a>, <a href="https://publications.waset.org/abstracts/search?q=QL4POMR" title=" QL4POMR"> QL4POMR</a>, <a href="https://publications.waset.org/abstracts/search?q=typegraphQL" title=" typegraphQL"> typegraphQL</a> </p> <a href="https://publications.waset.org/abstracts/155525/prototyping-the-problem-oriented-medical-record-for-connected-health-based-on-typegraphql" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155525.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">97</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">67</span> Exposure to Natural Outdoor Environment and Positive Health Impacts: A Synthesis of Empirical Research</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joris%20Zufferey">Joris Zufferey</a>, <a href="https://publications.waset.org/abstracts/search?q=Roderick%20John%20Lawrence"> Roderick John Lawrence</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper provides an overview of the state of the art about the positive health impacts of exposure to natural outdoor environments.

It was not designed securely and can be subject to attacks. DNS attacks have become more frequent and sophisticated and the need for detecting and preventing them becomes more important for the modern network. DNS tunnelling attacks are one type of attack that are primarily used for distributed denial-of-service (DDoS) attacks and data exfiltration.

We employ a sample of 45 countries between 2007 and 2020. We test for two related hypotheses; first, corruption hinders the smooth mobilisation of revenue through the tax system. Second, a rise in corruption amidst a defective tax system impairs inclusive development. We expect that a rise in the level of corruption in the economy will distort the tax system, thus affecting efficient revenue mobilisation and, subsequently, inclusive development. By extension, these findings have important policy implications for governments in containing corruption and building an effective tax system as it will help promote inclusive development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corruption" title="corruption">corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=tax%20systems" title=" tax systems"> tax systems</a>, <a href="https://publications.waset.org/abstracts/search?q=tax%20complexity" title=" tax complexity"> tax complexity</a> </p> <a href="https://publications.waset.org/abstracts/153765/corruption-tax-systems-and-inclusive-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153765.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">113</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">61</span> Film Diplomacy: An Approach to International Relations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lawrence%20Akande">Lawrence Akande</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the efforts of African countries' governments and the foreign countries' governments, there are cautions between the people of Africa and the people of other countries.

The high rate of informality in SSA worsens information asymmetry, which restricts the supply of funds in a heavily bank-led environment. In this paper, we ask whether the adoption of recent technological improvements in delivering financial services, such as crowdfunding, assists the financially excluded within Africa. Secondly, we investigate the individual determinants of crowdfunding, such as income, level of education, demographics, culture/trust, and the effects of crowdfunding on households’ usage of formal financial services.

There are an infinite number of game variations and design choices, and it is hard to systematically determine game design choices that will have positive experiences for players. In this work, we demonstrate how multi-arm bandits can be used to automatically explore game design variations to achieve improved player metrics. The advantage of multi-arm bandits is that they allow for continuous experimentation and variation, intrinsically converge to the best solution, and require no special infrastructure to use beyond allowing minor game variations to be deployed to users for evaluation. A user study confirms that applying multi-arm bandits was successful in determining the preferred game variation with highest play time metrics and can be a useful technique in a game designer's toolkit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=game%20design" title="game design">game design</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-arm%20bandit" title=" multi-arm bandit"> multi-arm bandit</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20exploration%20and%20data%20mining" title=" design exploration and data mining"> design exploration and data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=player%20metric%20optimization%20and%20analytics" title=" player metric optimization and analytics"> player metric optimization and analytics</a> </p> <a href="https://publications.waset.org/abstracts/56494/using-multi-arm-bandits-to-optimize-game-play-metrics-and-effective-game-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56494.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">510</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">58</span> Molluscicidal Effects of Ageratum conyzoids and Datura stramonium on Bulinus globosus and Lymnea natalensis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olofintoye%20Lawrence%20Kayode">Olofintoye Lawrence Kayode</a>, <a href="https://publications.waset.org/abstracts/search?q=Olorunniyi%20Omojola%20Felix"> Olorunniyi Omojola Felix</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Schistosomiasis is a vector-borne water-based disease transmitted by Bulinus globosus, causing haematuria in the urine of man, while fascioliasis is a trematode zoonosis infectious transmitted by Lymnaea natalensis causing liver disease in man and animals.

The study investigates the leaching properties of a low-grade copper ore by optimizing the leaching variables using response surface methodology. The effects of key parameters, i.e., temperature, solid to liquid ratio, stirring speed and pH, on the leaching rate constant was investigated using a pH stat apparatus. A Central Composite Design (CCD) of experiments was used to develop a quadratic model which specifically correlates the leaching variables and the rate constant. The results indicated that the model is in good agreement with the experimental data with a correlation coefficient (R2) of 0.93. The temperature and solid to liquid ratio were found to have the most substantial influence on the leaching rate constant. The optimum operating conditions for copper leaching from the ore were identified as temperature at 65C, solid to liquid ratio at 1.625 and stirring speed of 325 rpm which yielded an average leaching efficiency of 93.16%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=copper" title="copper">copper</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a>, <a href="https://publications.waset.org/abstracts/search?q=CCD" title=" CCD"> CCD</a>, <a href="https://publications.waset.org/abstracts/search?q=rate%20constant" title=" rate constant"> rate constant</a> </p> <a href="https://publications.waset.org/abstracts/59859/optimization-of-leaching-properties-of-a-low-grade-copper-ore-using-central-composite-design-ccd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59859.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">242</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> A Quantitative Study of Blackboard Utilisation at a University of Technology in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lawrence%20Meda">Lawrence Meda</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Dumas"> Christopher Dumas</a>, <a href="https://publications.waset.org/abstracts/search?q=Moses%20Moyo"> Moses Moyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Zayd%20Waghid"> Zayd Waghid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a result of some schools embracing technology to enhance students’ learning experiences in the digital era, the Faculty of Education at a University of Technology in South Africa has mandated lecturers to scale up their utilisation of technology in their teaching. Lecturers have been challenged to utilise the institution’s Learning Management System - Blackboard among other technologies - to adequately prepare trainee teachers to be able to teach competently in schools. The purpose of this study is to investigate the extent to which lecturers are utilising Blackboard to enhance their teaching. The study will be conducted using a quantitative approach, and its paradigmatic position will be positivist. The study will be done as a case study of the university’s Faculty of Education. Data will be extracted from all 100 lecturers’ Blackboard sites according to their respective modules, and it will be analysed using the four pillars of Blackboard as a conceptual framework. It is presumed that there is an imbalance on the lecturers’ utilisation of the four pillars of Blackboard as the majority use it as a content dumping site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blackboard" title="blackboard">blackboard</a>, <a href="https://publications.waset.org/abstracts/search?q=digital" title=" digital"> digital</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/100397/a-quantitative-study-of-blackboard-utilisation-at-a-university-of-technology-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100397.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">53</span> Connecting the Vulnerable in South Africa Through Urban Form and the Creation of Urban Moral Clusters - A Conceptual Analysis of Orphanages, Old Age Homes and Animal Cruelty Centres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clive%20Greenstone">Clive Greenstone</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiara%20Lawrence"> Kiara Lawrence</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This conceptual paper explains certain influences of urban planning and urban form on the design layout of housing specific vulnerable members of society.

This conceptual paper offers a more appropriate approach to both offer better urban settlements as well as help solve several challenges facing the most vulnerable groups in society, namely, the elderly, vulnerable children and vulnerable domestic animals into new housing settlements that create better social connections and physical and emotional well-being, labeled urban moral clusters. This conceptual paper offers two potential case studies where these new moral clusters can be implemented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title="vulnerability">vulnerability</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusivity" title=" inclusivity"> inclusivity</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20planning" title=" urban planning"> urban planning</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20capital" title=" social capital"> social capital</a>, <a href="https://publications.waset.org/abstracts/search?q=moral%20clusters" title=" moral clusters"> moral clusters</a> </p> <a href="https://publications.waset.org/abstracts/193116/connecting-the-vulnerable-in-south-africa-through-urban-form-and-the-creation-of-urban-moral-clusters-a-conceptual-analysis-of-orphanages-old-age-homes-and-animal-cruelty-centres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193116.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">17</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> Application of Generalized Autoregressive Score Model to Stock Returns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katleho%20Daniel%20Makatjane">Katleho Daniel Makatjane</a>, <a href="https://publications.waset.org/abstracts/search?q=Diteboho%20Lawrence%20Xaba"> Diteboho Lawrence Xaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Ntebogang%20Dinah%20Moroke"> Ntebogang Dinah Moroke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current study investigates the behaviour of time-varying parameters that are based on the score function of the predictive model density at time t. The mechanism to update the parameters over time is the scaled score of the likelihood function. The results revealed that there is high persistence of time-varying, as the location parameter is higher and the skewness parameter implied the departure of scale parameter from the normality with the unconditional parameter as 1.5. The results also revealed that there is a perseverance of the leptokurtic behaviour in stock returns which implies the returns are heavily tailed. Prior to model estimation, the White Neural Network test exposed that the stock price can be modelled by a GAS model. Finally, we proposed further researches specifically to model the existence of time-varying parameters with a more detailed model that encounters the heavy tail distribution of the series and computes the risk measure associated with the returns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=generalized%20autoregressive%20score%20model" title="generalized autoregressive score model">generalized autoregressive score model</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20returns" title=" stock returns"> stock returns</a>, <a href="https://publications.waset.org/abstracts/search?q=time-varying" title=" time-varying"> time-varying</a> </p> <a href="https://publications.waset.org/abstracts/78817/application-of-generalized-autoregressive-score-model-to-stock-returns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78817.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">501</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">51</span> Maintaining a Motivated Workforce in the Malaysian Armed Forces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerard%20Lawrence">Gerard Lawrence</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper gives an in-depth discussion on Motivation in the Malaysian Armed Forces; highlighting it as a powerful and important tool upon which the well-being of an entire (or any) organization rests. It starts with the literal definition of the word and then the psychological aspects of it detailing the intricate mechanics and fundamentals in order to accurately and systematically harness it to create a motivated workforce. It then describes the types of motivation; positive and negative, its many facets and manifestation, clearly identifying each one point by point as well as drawing examples. The paper also deals with certain controversial practices like favoritism; nepotism and provides examples of military motivation both in historic and contemporary context. It strips the current system (and its flaws) to build, nurture and maintain motivation in the future. It shows how “past practice” may not necessarily be “best practice”, by providing the building blocks necessary to move forward and cautions on the inter-relation and differences between morale and motivation. As a conclusion the paper coins a theory of working in shifts for the military and urges careful research and planning as to IF this can raise if not maintain motivation in the new era. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=armed%20forces" title="armed forces">armed forces</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysia" title=" Malaysia"> Malaysia</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=military%20psychology" title=" military psychology"> military psychology</a> </p> <a href="https://publications.waset.org/abstracts/29776/maintaining-a-motivated-workforce-in-the-malaysian-armed-forces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29776.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">435</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> Metamorphosis in Nature through Adéquation: An Ecocritical Reading of Charles Tomlinson's Poetry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Barzegar">Zahra Barzegar</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Deedari"> Reza Deedari</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Pourgharib"> Behzad Pourgharib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines how metamorphosis in nature is depicted in Charles Tomlinson's poetry through Lawrence Buell's mimesis and referential strategy of adéquation. This study aims to answer the questions that what is the relationship between Tomlinson's selected poems and nature, and how does Tomlinson's poetry bring the reader close to the natural environment. Adéquation is a way that brings the reader close to nature, not by imitating nature but by referring to it imaginatively and creating a stylized image. Using figurative language, namely imagery, metaphor, and analogy, adéquation creates a stylized image of metamorphosis in a nature scene that acts as a middle way between the reader and nature. This paper proves that adéquation reinvents the metamorphosis in natural occurrences in Charles Tomlinson's selected poems. Thus, a reader whose imagination is addressed achieves closeness with nature and a caring outlook toward natural happenings. This article confirms that Tomlinson's poems are potential enough to represent metamorphosis in nature through adéquation. Therefore, the reader understands nature beyond the poem as the poem presents a gist of nature through adéquation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ad%C3%A9quation" title="adéquation">adéquation</a>, <a href="https://publications.waset.org/abstracts/search?q=metamorphosis" title=" metamorphosis"> metamorphosis</a>, <a href="https://publications.waset.org/abstracts/search?q=nature" title=" nature"> nature</a>, <a href="https://publications.waset.org/abstracts/search?q=referentiality" title=" referentiality"> referentiality</a> </p> <a href="https://publications.waset.org/abstracts/144079/metamorphosis-in-nature-through-adequation-an-ecocritical-reading-of-charles-tomlinsons-poetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144079.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">186</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">49</span> On the Grid Technique by Approximating the Derivatives of the Solution of the Dirichlet Problems for (1+1) Dimensional Linear Schrodinger Equation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lawrence%20A.%20Farinola">Lawrence A.

The Grid method is also applied to the mixed second derivative of the solution of the Linear Schrodinger time-dependent equation.

A thorough review of the factors that lead organisations, in the different industries, to implement these methodologies was done. L&SS applications were found to be prominent in the automotive industry. In particular, the railway industry in SA and the region were reviewed in terms of challenges in capturing the freight logistics market and growing market share. Qualitative methods have been used to collect primary data and descriptive statistics was used to calculate, describe, and summarize collected research data. The results show that external factors have a greater influence on the implementation of L&SS. The study drew inferences between freight railway supplier base and the application of Lean and Six Sigma (L&SS) methodologies in the SA context. It identified challenges that leads the SA freight railway to lose market share to road freight users. It further observes and recommends that L&SS methodologies are the ideal strategy required to implement a turnaround in the trajectory of freight railways as a competitive freight transport solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=production" title="production">production</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing" title=" manufacturing"> manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=lean" title=" lean"> lean</a>, <a href="https://publications.waset.org/abstracts/search?q=six%20sigma" title=" six sigma"> six sigma</a> </p> <a href="https://publications.waset.org/abstracts/182206/lean-and-six-sigma-in-the-freight-railway-supplier-base-in-south-africa-factors-leading-to-their-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182206.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">45</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">47</span> Multi-Template Molecularly Imprinted Polymer: Synthesis, Characterization and Removal of Selected Acidic Pharmaceuticals from Wastewater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lawrence%20Mzukisi%20Madikizela">Lawrence Mzukisi Madikizela</a>, <a href="https://publications.waset.org/abstracts/search?q=Luke%20Chimuka"> Luke Chimuka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Removal of organics from wastewater offers a better water quality, therefore, the purpose of this work was to investigate the use of molecularly imprinted polymer (MIP) for the elimination of selected organics from water. A multi-template MIP for the adsorption of naproxen, ibuprofen and diclofenac was synthesized using a bulk polymerization method. A MIP was synthesized at 70°C by employing 2-vinylpyridine, ethylene glycol dimethacrylate, toluene and 1,1’-azobis-(cyclohexanecarbonitrile) as functional monomer, cross-linker, porogen and initiator, respectively. Thermogravimetric characterization indicated that the polymer backbone collapses at 250°C and scanning electron microscopy revealed the porous and roughness nature of the MIP after elution of templates. The performance of the MIP in aqueous solutions was evaluated by optimizing several adsorption parameters. The optimized adsorption conditions were 50 mg of MIP, extraction time of 10 min, a sample pH of 4.6 and the initial concentration of 30 mg/L. The imprinting factors obtained for naproxen, ibuprofen and diclofenac were 1.25, 1.42, and 2.01, respectively. The order of selectivity for the MIP was; diclofenac > ibuprofen > naproxen. MIP showed great swelling in water with an initial swelling rate of 2.62 g/(g min). The synthesized MIP proved to be able to adsorb naproxen, ibuprofen and diclofenac from contaminated deionized water, wastewater influent and effluent. <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=molecularly%20imprinted%20polymer" title=" molecularly imprinted polymer"> molecularly imprinted polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20template" title=" multi template"> multi template</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceuticals" title=" pharmaceuticals"> pharmaceuticals</a> </p> <a href="https://publications.waset.org/abstracts/43263/multi-template-molecularly-imprinted-polymer-synthesis-characterization-and-removal-of-selected-acidic-pharmaceuticals-from-wastewater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43263.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">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> An Improved Image Steganography Technique Based on Least Significant Bit Insertion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olaiya%20Folorunsho">Olaiya Folorunsho</a>, <a href="https://publications.waset.org/abstracts/search?q=Comfort%20Y.%20Daramola"> Comfort Y.

Conversely, there is a continuous growth of unauthorized access to confidential data. This has posed a challenge to information security expertise whose major goal is to curtail the menace. One of the approaches to secure the safety delivery of data/information to the rightful destination without any modification is steganography. Steganography is the art of hiding information inside an embedded information. This research paper aimed at designing a secured algorithm with the use of image steganographic technique that makes use of Least Significant Bit (LSB) algorithm for embedding the data into the bit map image (bmp) in order to enhance security and reliability. In the LSB approach, the basic idea is to replace the LSB of the pixels of the cover image with the Bits of the messages to be hidden without destroying the property of the cover image significantly. The system was implemented using C# programming language of Microsoft.NET framework. The performance evaluation of the proposed system was experimented by conducting a benchmarking test for analyzing the parameters like Mean Squared Error (MSE) and Peak Signal to Noise Ratio (PSNR). The result showed that image steganography performed considerably in securing data hiding and information transmission over the networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steganography" title="steganography">steganography</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20steganography" title=" image steganography"> image steganography</a>, <a href="https://publications.waset.org/abstracts/search?q=least%20significant%20bits" title=" least significant bits"> least significant bits</a>, <a href="https://publications.waset.org/abstracts/search?q=bit%20map%20image" title=" bit map image"> bit map image</a> </p> <a href="https://publications.waset.org/abstracts/57080/an-improved-image-steganography-technique-based-on-least-significant-bit-insertion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57080.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">266</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Nutritional Quality Assessment and Safety Evaluation of Food Crops</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olawole%20Emmanuel%20Aina">Olawole Emmanuel Aina</a>, <a href="https://publications.waset.org/abstracts/search?q=Liziwe%20Lizbeth%20Mugivhisa"> Liziwe Lizbeth Mugivhisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Joshua%20Oluwole%20Olowoyo"> Joshua Oluwole Olowoyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Chikwela%20Lawrence%20Obi"> Chikwela Lawrence Obi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In sustained and consistent efforts to improve food security, numerous and different methods are proposed and used in the production of food crops, and farm produce to meet the demands of consumers. However, unregulated and indiscriminate methods of production present another problem that may expose consumers of these food crops to potential health risks. Therefore, it is imperative that a thorough assessment of farm produce is carried out due to the growing trend of health-conscious consumers preference for minimally processed or raw farm produce. This study evaluated the safety and nutritional quality of food crops. The objectives were to compare the nutritional quality of organic and inorganic farm produce in one hand and, on the other, evaluate the safety of farm produce with respect to trace metal and pathogenic contamination. We conducted a broad systematic search of peer-reviewed published literatures from databases and search engines such as science direct, web-of-science, Google scholar, and Scopus. This study concluded that there is no conclusive evidence to support the notion of nutritional superiority of organic food crops over their inorganic counterparts and there are documented reports of pathogenic and metal contaminations of food crops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20crops" title="food crops">food crops</a>, <a href="https://publications.waset.org/abstracts/search?q=fruits%20and%20vegetables" title=" fruits and vegetables"> fruits and vegetables</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogens" title=" pathogens"> pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=trace%20metals" title=" trace metals"> trace metals</a> </p> <a href="https://publications.waset.org/abstracts/167258/nutritional-quality-assessment-and-safety-evaluation-of-food-crops" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167258.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">80</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">44</span> The Development of a Miniaturized Raman Instrument Optimized for the Detection of Biosignatures on Europa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aria%20Vitkova">Aria Vitkova</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanna%20Sykulska-Lawrence"> Hanna Sykulska-Lawrence</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, Europa has been one of the major focus points in astrobiology due to its high potential of harbouring life in the vast ocean underneath its icy crust. However, the detection of life on Europa faces many challenges due to the harsh environmental conditions and mission constraints. Raman spectroscopy is a highly capable and versatile in-situ characterisation technique that does not require any sample preparation. It has only been used on Earth to date; however, recent advances in optical and laser technology have also allowed it to be considered for extraterrestrial exploration. So far, most efforts have been focused on the exploration of Mars, the most imminent planetary target. However, as an emerging technology with high miniaturization potential, Raman spectroscopy also represents a promising tool for the exploration of Europa. In this study, the capabilities of Raman technology in terms of life detection on Europa are explored and assessed. Spectra of biosignatures identified as high priority molecular targets for life detection on Europa were acquired at various excitation wavelengths and conditions analogous to Europa. The effects of extremely low temperatures and low concentrations in water ice were explored and evaluated in terms of the effectiveness of various configurations of Raman instruments. Based on the findings, a design of a miniaturized Raman instrument optimized for in-situ detection of life on Europa is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=astrobiology" title="astrobiology">astrobiology</a>, <a href="https://publications.waset.org/abstracts/search?q=biosignatures" title=" biosignatures"> biosignatures</a>, <a href="https://publications.waset.org/abstracts/search?q=Europa" title=" Europa"> Europa</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20detection" title=" life detection"> life detection</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20Spectroscopy" title=" Raman Spectroscopy"> Raman Spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/124524/the-development-of-a-miniaturized-raman-instrument-optimized-for-the-detection-of-biosignatures-on-europa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124524.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">212</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">43</span> Role of Interlukin-18 in Primary Knee Osteoarthritis: Clinical, Laboratory and Radiological Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Khalil%20Ibrahim">Ibrahim Khalil Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Enas%20Mohamed%20Shahine"> Enas Mohamed Shahine</a>, <a href="https://publications.waset.org/abstracts/search?q=Abeer%20Shawky%20El%20Hadedy"> Abeer Shawky El Hadedy</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba"> Emmanuel Kamal Aziz Saba</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Salah%20Attia%20Hussein"> Ghada Salah Attia Hussein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Osteoarthritis (OA) is a multifactorial disease characterized by a progressive degradation of articular cartilage and is the leading cause of disability in elderly persons. IL-18 contributes to the destruction of cartilage and bone in the disease process of arthritis. The aim of the study was to investigate the role of IL-18 in primary knee OA patients. Serum level of IL-18 was assessed by enzyme-linked immunosorbent assay in 30 primary knee OA patients and compared to 20 age and gender-matched healthy volunteers as a control group. Radiographic severity of OA was assessed by Kellgren and Lawrence (KL) global scale. Pain, stiffness and functional assessment were done using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). OA patients had significantly higher serum IL-18 level than in control group (420.93 ± 345.4 versus 151.03 ± 144.16 pg/ml, P=0.001). Serum level of IL-18 was positively correlated with KL global scale (P=0.001). There were no statistically significant correlations between serum level of IL-18 and pain, stiffness, function subscales and total WOMAC index scores among the studied patients. In conclusions, IL-18 has a role in the pathogenesis of OA and it is positively correlated with the radiographic damage of OA. <p class="card-text"><strong>Keywords:</strong> <a
