collected and shared by a large number of individuals or organizations, often through the use of digital technologies such as mobile devices and social media. The shortage in crash data collection in developing countries makes it difficult to fully understand and address road safety issues in these regions. In developing countries, crowd-sourced data can be a valuable tool for improving road safety, particularly in urban areas where the majority of road crashes occur. This study is -to our best knowledge- the first to develop safety performance functions using crowd-sourced data by adopting a negative binomial structure model and the Full Bayes model to investigate traffic safety for urban road networks and provide insights into the impact of roadway characteristics. Furthermore, as a part of the safety management process, network screening has been undergone through applying two different methods to rank the most hazardous road segments: PCR method (adopted in the Highway Capacity Manual HCM) as well as a graphical method using GIS tools to compare and validate. Lastly, recommendations were suggested for policymakers to ensure safer roads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crowdsourced%20data" title="crowdsourced data">crowdsourced data</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20crashes" title=" road crashes"> road crashes</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20performance%20functions" title=" safety performance functions"> safety performance functions</a>, <a href="https://publications.waset.org/abstracts/search?q=Full%20Bayes%20models" title=" Full Bayes models"> Full Bayes models</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20screening" title=" network screening"> network screening</a> </p> <a href="https://publications.waset.org/abstracts/187824/using-crowd-sourced-data-to-assess-safety-in-developing-countries-the-case-study-of-eastern-cairo-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187824.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">52</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">1706</span> Presuppositions and Implicatures in Four Selected Speeches of Osama Bin Laden's Legitimisation of 'Jihad'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sawsan%20Al-Saaidi">Sawsan Al-Saaidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghayth%20K.%20Shaker%20Al-Shaibani"> Ghayth K. Shaker Al-Shaibani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates certain linguistics properties of four selected speeches by Al-Qaeda’s former leader Osama bin Laden who legitimated the use of jihad by Muslims in various countries when he was alive. The researchers adopt van Dijk’s (2009; 1998) Socio-Cognitive approach and Ideological Square theory respectively. Socio-Cognitive approach revolves around various cognitive, socio-political, and discursive aspects that can be found in political discourse as in Osama bin Laden’s one. The political discourse can be defined in terms of textual properties and contextual models. Pertaining to the ideological square, it refers to positive self-presentation and negative other-presentation which help to enhance the textual and contextual analyses. Therefore, among the most significant properties in Osama bin Laden’s discourse are the use of presuppositions and implicatures which are based on background knowledge and contextual models as well. Thus, the paper concludes that Osama bin Laden used a number of manipulative strategies which augmented and embellished the use of ‘jihad’ in order to develop a more effective discourse for his audience. In addition, the findings have revealed that bin Laden used different implicit and embedded interpretations of different topics which have been accepted as taken-for-granted truths for him to legitimate Jihad against his enemies. There are many presuppositions in the speeches analysed that result in particular common-sense assumptions and a world-view about the selected speeches. More importantly, the assumptions in the analysed speeches help consolidate the ideological analysis in terms of in-group and out-group members. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-Qaeda" title="Al-Qaeda">Al-Qaeda</a>, <a href="https://publications.waset.org/abstracts/search?q=cognition" title=" cognition"> cognition</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20discourse%20analysis" title=" critical discourse analysis"> critical discourse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Osama%20Bin%20Laden" title=" Osama Bin Laden"> Osama Bin Laden</a>, <a href="https://publications.waset.org/abstracts/search?q=jihad" title=" jihad"> jihad</a>, <a href="https://publications.waset.org/abstracts/search?q=implicature" title=" implicature"> implicature</a>, <a href="https://publications.waset.org/abstracts/search?q=legitimisation" title=" legitimisation"> legitimisation</a>, <a href="https://publications.waset.org/abstracts/search?q=presupposition" title=" presupposition"> presupposition</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20discourse" title=" political discourse"> political discourse</a> </p> <a href="https://publications.waset.org/abstracts/85958/presuppositions-and-implicatures-in-four-selected-speeches-of-osama-bin-ladens-legitimisation-of-jihad" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85958.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">239</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">1705</span> Effects of Asphalt Modification with Nanomaterials on Fresh and Stored Bitumen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20W.%20Oda">Ahmed W.

Two locally produced nanomaterials were used in the asphalt binder modification. The nanomaterials used are Nanosilica (NS), and Nanoclay (NC). The virgin asphalt binder was characterized by the conventional tests. The bitumen was modified by 3%, 5% and 7% of NS and NC. The penetration index(PI), and the retaining penetration (RP) was calculated based on the results of the penetration and the softening point tests. The results show that the RP becomes 95.35% at 5%NS modified bitumen and reaches 97.56% when bitumen is modified with 3% NC. The results show significant improvement in the bitumen stiffness when modified by the two types of nanomaterials, either fresh or aged (stored). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bitumen" title="bitumen">bitumen</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20bitumen" title=" modified bitumen"> modified bitumen</a>, <a href="https://publications.waset.org/abstracts/search?q=aged" title=" aged"> aged</a>, <a href="https://publications.waset.org/abstracts/search?q=stored" title="stored">stored</a>, <a href="https://publications.waset.org/abstracts/search?q=nanomaterials" title=" nanomaterials"> nanomaterials</a> </p> <a href="https://publications.waset.org/abstracts/146856/effects-of-asphalt-modification-with-nanomaterials-on-fresh-and-stored-bitumen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146856.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">193</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">1704</span> Prevalence and Clinical Significance of Antiphospholipid Antibodies in COVID-19 Patients Admitted to Intensive Care Units</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Najim">Mostafa Najim</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Rahhal"> Alaa Rahhal</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadi%20Khir"> Fadi Khir</a>, <a href="https://publications.waset.org/abstracts/search?q=Safae%20Abu%20Yousef"> Safae Abu Yousef</a>, <a href="https://publications.waset.org/abstracts/search?q=Amer%20Aljundi"> Amer Aljundi</a>, <a href="https://publications.waset.org/abstracts/search?q=Feryal%20Ibrahim"> Feryal Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Aliaa%20Amer"> Aliaa Amer</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Soliman%20Mohamed"> Ahmed Soliman Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Samira%20Saleh"> Samira Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dekra%20Alfaridi"> Dekra Alfaridi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mahfouz"> Ahmed Mahfouz</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumaya%20Al-Yafei"> Sumaya Al-Yafei</a>, <a href="https://publications.waset.org/abstracts/search?q=Faraj%20Howady"> Faraj Howady</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Yahya%20%20Khatib"> Mohamad Yahya Khatib</a>, <a href="https://publications.waset.org/abstracts/search?q=Samar%20Alemadi"> Samar Alemadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Coronavirus disease 2019 (COVID-19) increases the risk of coagulopathy among critically ill patients. Although the presence of antiphospholipid antibodies (aPLs) has been proposed as a possible mechanism of COVID-19 induced coagulopathy, their clinical significance among critically ill patients with COVID-19 remains uncertain. Methods: This prospective observational study included patients with COVID-19 admitted to intensive care units (ICU) to evaluate the prevalence and clinical significance of aPLs, including anticardiolipin IgG/IgM, anti-β2-glycoprotein IgG/IgM, and lupus anticoagulant. The study outcomes included the prevalence of aPLs, a primary composite outcome of all-cause mortality, and arterial or venous thrombosis among aPLs positive patients versus aPLs negative patients during their ICU stay. Multiple logistic regression was used to assess the influence of aPLs on the primary composite outcome of mortality and thrombosis. Results: A total of 60 critically ill patients were enrolled. Of whom, 57 (95%) were male, with a mean age of 52.8 ± 12.2 years, and the majority were from Asia (68%). Twenty-two patients (37%) were found to have positive aPLs; of whom 21 patients were positive for lupus anticoagulant, whereas one patient was positive for anti-β2-glycoprotein IgG/IgM. The composite outcome of mortality and thrombosis during ICU did not differ among patients with positive aPLs compared to those with negative aPLs (4 (18%) vs. 6 (16%), aOR= 0.98, 95% CI 0.1-6.7; p-value= 0.986). Likewise, the secondary outcomes, including all-cause mortality, venous thrombosis, arterial thrombosis, discharge from ICU, time to mortality, and time to discharge from ICU, did not differ between those with positive aPLs upon ICU admission in comparison to patients with negative aPLs. Conclusion: The presence of aPLs does not seem to affect the outcomes of critically ill patients with COVID-19 in terms of all-cause mortality and thrombosis. Therefore, clinicians may not screen critically ill patients with COVID-19 for aPLs unless deemed clinically appropriate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiphospholipid%20antibodies" title="antiphospholipid antibodies">antiphospholipid antibodies</a>, <a href="https://publications.waset.org/abstracts/search?q=critically%20ill%20patients" title=" critically ill patients"> critically ill patients</a>, <a href="https://publications.waset.org/abstracts/search?q=coagulopathy" title=" coagulopathy"> coagulopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=coronavirus" title=" coronavirus"> coronavirus</a> </p> <a href="https://publications.waset.org/abstracts/131723/prevalence-and-clinical-significance-of-antiphospholipid-antibodies-in-covid-19-patients-admitted-to-intensive-care-units" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131723.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">166</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">1703</span> Developing an Interpretive Plan for Qubbet El-Hawa North Archaeological Site in Aswan, Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osama%20Amer%20Mohyeldin%20Mohamed">Osama Amer Mohyeldin Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Qubbet el-Hawa North (QHN) is an example of an archaeological site in West-Aswan and It has not opened to the public yet and has been under excavation since its discovery in 2013 as a result of the illegal digging that happened in many sites in Egypt because of the unstable situation and the absence of security. The site has the potential to be one of the most attractive sites in Aswan. Moreover, it deserves to be introduced to the visitors in a good manner appropriate to its great significance. Both interpretation and presentation are crucial inseparable tools that communicate the archaeological site's significance to the public and raise their awareness. Moreover, it helps them to understand the past and appreciate archaeological assets. People will never learn or see anything from ancient remains unless it is explained. They would only look at it as ancient and charming. They expect a story, and more than knowledge, authenticity, or even supporting preservation actions, they want to enjoy and be entertained. On the other hand, a lot of archaeologists believe that planning an archaeological site for entertaining visitors deteriorates it and affects its authenticity. Thus, it represents a challenge to design a model for visitors’ experience that meets their expectations and needs while safeguarding the site’s integrity. The article presents a proposal for an interpretation plan for the site of Qubbet el-Hawa North. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heritage%20interpretation%20and%20presentation" title="heritage interpretation and presentation">heritage interpretation and presentation</a>, <a href="https://publications.waset.org/abstracts/search?q=archaeological%20site%20management" title=" archaeological site management"> archaeological site management</a>, <a href="https://publications.waset.org/abstracts/search?q=qubbet%20el-hawa%20North" title=" qubbet el-hawa North"> qubbet el-hawa North</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20community%20engagement" title=" local community engagement"> local community engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=accessibility" title=" accessibility"> accessibility</a> </p> <a href="https://publications.waset.org/abstracts/187449/developing-an-interpretive-plan-for-qubbet-el-hawa-north-archaeological-site-in-aswan-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187449.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">28</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">1702</span> Experimental Investigation on the Mechanical Behaviour of Three-Leaf Masonry Walls under In-Plane Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osama%20Amer">Osama Amer</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaser%20Abdel-Aty"> Yaser Abdel-Aty</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abd%20El%20Hady"> Mohamed Abd El Hady</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper illustrates an experimental approach to provide understanding of the mechanical behavior and failure mechanisms of different typologies of unreinforced three-leaf masonry walls of historical Islamic architectural heritage in Egypt. The main objective of this study is to investigate the propagation of possible cracking, ultimate load, deformations and failure mechanisms. Experimental data on interface-shear and compression tests on large scale three-leaf masonry wallets are provided. The wallets were built basically of Egyptian limestone and modified lime mortar. External wallets were built of stone blocks while the inner leaf was built of rubble limestone. Different loading conditions and dimensions of core layer for two types of collar joints (with and without shear keys) are considered in the tests. Mechanical properties of the constituent materials of masonry were tested and a database of characteristic properties was created. The results of the experiments will highlight the properties, force-displacement curves, stress distribution of multiple-leaf masonry walls contributing to the derivation of rational design rules and validation of numerical models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=masonry" title="masonry">masonry</a>, <a href="https://publications.waset.org/abstracts/search?q=three-leaf%20walls" title=" three-leaf walls"> three-leaf walls</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behavior" title=" mechanical behavior"> mechanical behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=testing" title=" testing"> testing</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20heritage" title=" architectural heritage"> architectural heritage</a> </p> <a href="https://publications.waset.org/abstracts/48229/experimental-investigation-on-the-mechanical-behaviour-of-three-leaf-masonry-walls-under-in-plane-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48229.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">291</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">1701</span> Effectiveness of Adopting Software Quality Frameworks in Software Organizations: A Qualitative Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20K.%20Amer">Sarah K.

Although the cultivated barley genome is well studied, little is known about genome structure and function of its wild ancestor. In the present study, RNA-Seq analysis was performed on young leaves of wild barley treated with salt (500 mM NaCl) at four different time intervals. Transcriptome sequencing yielded 103 to 115 million reads for all replicates of each treatment, corresponding to over 10 billion nucleotides per sample. Of the total reads, between 74.8 and 80.3% could be mapped and 77.4 to 81.7% of the transcripts were found in the H. vulgare unigene database (unigene-mapped). The unmapped wild barley reads for all treatments and replicates were assembled de novo and the resulting contigs were used as a new reference genome. This resultedin94.3 to 95.3%oftheunmapped reads mapping to the new reference. The number of differentially expressed transcripts was 9277, 3861 of which were uni gene-mapped. The annotated unigene- and de novo-mapped transcripts (5100) were utilized to generate expression clusters across time of salt stress treatment. Two-dimensional hierarchical clustering classified differential expression profiles into nine expression clusters, four of which were selected for further analysis. Differentially expressed transcripts were assigned to the main functional categories. The most important groups were ‘response to external stimulus’ and ‘electron-carrier activity’. Highly expressed transcripts are involved in several biological processes, including electron transport and exchanger mechanisms, flavonoid biosynthesis, reactive oxygen species (ROS) scavenging, ethylene production, signaling network and protein refolding. The comparisons demonstrated that mRNA-Seq is an efficient method for the analysis of differentially expressed genes and biological processes under salt stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electron%20transport" title="electron transport">electron transport</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoid%20biosynthesis" title=" flavonoid biosynthesis"> flavonoid biosynthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20oxygen%20species" title=" reactive oxygen species"> reactive oxygen species</a>, <a href="https://publications.waset.org/abstracts/search?q=rnaseq" title=" rnaseq"> rnaseq</a> </p> <a href="https://publications.waset.org/abstracts/42511/rna-seq-analysis-of-the-wild-barley-h-spontaneum-leaf-transcriptome-under-salt-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42511.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">392</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">1698</span> Isolation and Molecular Identification of Two Fungal Strains Capable of Degrading hydrocarbon Contaminants on Saudi Arabian Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amr%20A.%20EL%20Hanafy">Amr A.

Analysis of ITS-1, ITS-2 and amplicon pyrosequencing studies of fungal diversity revealed that these strains belong to Penicillium and Aspergillus species. Two strains that proved to be the most efficient in degrading crude oil was Aspergillus niger (54 %) and Penicillium commune (48 %) Subsequent to two weeks of cultivation in BHS medium the degradation rate were recorded by using spectrophotometer and GC-MS. Hence, it is cleared that these fungal strains has the capability of degradation and can be utilized for cleaning the Saudi Arabian environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fungal%20%20strains" title="fungal strains">fungal strains</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20contaminants" title=" hydrocarbon contaminants"> hydrocarbon contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20identification" title=" molecular identification"> molecular identification</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradation" title=" biodegradation"> biodegradation</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a> </p> <a href="https://publications.waset.org/abstracts/36036/isolation-and-molecular-identification-of-two-fungal-strains-capable-of-degrading-hydrocarbon-contaminants-on-saudi-arabian-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36036.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">522</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">1697</span> A Next Generation Multi-Scale Modeling Theatre for in silico Oncology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safee%20Chaudhary">Safee Chaudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahnoor%20Naseer%20Gondal"> Mahnoor Naseer Gondal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hira%20Anees%20Awan"> Hira Anees Awan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Rehman"> Abdul Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Arif"> Ammar Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Risham%20Hussain"> Risham Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Huma%20Khawar"> Huma Khawar</a>, <a href="https://publications.waset.org/abstracts/search?q=Zainab%20Arshad"> Zainab Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Faizyab%20Ali%20Chaudhary"> Muhammad Faizyab Ali Chaudhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Ahmed"> Waleed Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Umer%20Sultan"> Muhammad Umer Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bibi%20Amina"> Bibi Amina</a>, <a href="https://publications.waset.org/abstracts/search?q=Salaar%20Khan"> Salaar Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Moaz%20Ahmad"> Muhammad Moaz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Osama%20Shiraz%20Shah"> Osama Shiraz Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadia%20Hameed"> Hadia Hameed</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Farooq%20Ahmad%20Butt"> Muhammad Farooq Ahmad Butt</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ahmad"> Muhammad Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Sameer%20Ahmed"> Sameer Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Fayyaz%20Ahmed"> Fayyaz Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Omer%20Ishaq"> Omer Ishaq</a>, <a href="https://publications.waset.org/abstracts/search?q=Waqar%20Nabi"> Waqar Nabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Wim%20Vanderbauwhede"> Wim Vanderbauwhede</a>, <a href="https://publications.waset.org/abstracts/search?q=Bilal%20Wajid"> Bilal Wajid</a>, <a href="https://publications.waset.org/abstracts/search?q=Huma%20Shehwana"> Huma Shehwana</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Tariq"> Muhammad Tariq</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Faisal"> Amir Faisal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cancer is a manifestation of multifactorial deregulations in biomolecular pathways. These deregulations arise from the complex multi-scale interplay between cellular and extracellular factors. Such multifactorial aberrations at gene, protein, and extracellular scales need to be investigated systematically towards decoding the underlying mechanisms and orchestrating therapeutic interventions for patient treatment. In this work, we propose ‘TISON’, a next-generation web-based multiscale modeling platform for clinical systems oncology. TISON’s unique modeling abstraction allows a seamless coupling of information from biomolecular networks, cell decision circuits, extra-cellular environments, and tissue geometries. The platform can undertake multiscale sensitivity analysis towards in silico biomarker identification and drug evaluation on cellular phenotypes in user-defined tissue geometries. Furthermore, integration of cancer expression databases such as The Cancer Genome Atlas (TCGA) and Human Proteome Atlas (HPA) facilitates in the development of personalized therapeutics. TISON is the next-evolution of multiscale cancer modeling and simulation platforms and provides a ‘zero-code’ model development, simulation, and analysis environment for application in clinical settings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=systems%20oncology" title="systems oncology">systems oncology</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20systems%20biology" title=" cancer systems biology"> cancer systems biology</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20therapeutics" title=" cancer therapeutics"> cancer therapeutics</a>, <a href="https://publications.waset.org/abstracts/search?q=personalized%20therapeutics" title=" personalized therapeutics"> personalized therapeutics</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20modelling" title=" cancer modelling"> cancer modelling</a> </p> <a href="https://publications.waset.org/abstracts/112569/a-next-generation-multi-scale-modeling-theatre-for-in-silico-oncology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112569.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">222</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">1696</span> Rainfall-Runoff Forecasting Utilizing Genetic Programming Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Najah%20Ahmed%20Al-Mahfoodh">Ahmed Najah Ahmed Al-Mahfoodh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Najah%20Ahmed%20%20Al-Mahfoodh"> Ali Najah Ahmed Al-Mahfoodh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Al-Shafie"> Ahmed Al-Shafie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, genetic programming (GP) technique has been investigated in prediction of set of rainfall-runoff data.

A density-dependent version of the M3Y interaction (CDM3Y6), which is based on the G-matrix elements of the Paris NN potential, has been used. Volumetric integrals of the real and imaginary potential depth (JR, JW) have been calculated and found to be energy dependent.

Specifically, we demonstrate the feasibility of capturing and representing expressive provenance metadata, including more of the context for citing scholarly works (e.g., the authors’ explicit or inferred intentions at the time of developing his/her research content for publication), while also supporting subsequent augmentation with similar additional metadata (by third parties, be they human or automated). To better capture the nature and types of possible citations, in our proposed provenance scheme metaScribe, we extend standard provenance conceptual models to form our proposed provCite ontology. This provides a conceptual framework which can accurately capture and describe more of the functional and rhetorical properties of a citation than can be achieved with any current models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20representation" title="knowledge representation">knowledge representation</a>, <a href="https://publications.waset.org/abstracts/search?q=provenance%20architecture" title=" provenance architecture"> provenance architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=metadata" title=" metadata"> metadata</a>, <a href="https://publications.waset.org/abstracts/search?q=bibliographic%20citation" title=" bibliographic citation"> bibliographic citation</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20web%20annotation" title=" semantic web annotation"> semantic web annotation</a> </p> <a href="https://publications.waset.org/abstracts/137227/provenance-in-scholarly-publications-introducing-the-provcite-ontology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137227.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">117</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">1692</span> High Secure Data Hiding Using Cropping Image and Least Significant Bit Steganography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20A.%20Al-Afandy">Khalid A.

The predefined certain secret coordinate crops will be extracted from the cover image. The secret text message will be divided into sections. These sections quantity is equal the image crops quantity. Each section from the secret text message will embed into an image crop with a secret sequence using LSB technique. The embedding is done using the cover image color channels. Stego image is given by reassembling the image and the stego crops. The results of the technique will be compared to the other state of art techniques. Evaluation is based on visualization to detect any degradation of stego image, the difficulty of extracting the embedded data by any unauthorized viewer, Peak Signal-to-Noise Ratio of stego image (PSNR), and the embedding algorithm CPU time. Experimental results ensure that the proposed technique is more secure compared with the other traditional techniques. <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=stego" title=" stego"> stego</a>, <a href="https://publications.waset.org/abstracts/search?q=LSB" title=" LSB"> LSB</a>, <a href="https://publications.waset.org/abstracts/search?q=crop" title=" crop"> crop</a> </p> <a href="https://publications.waset.org/abstracts/44747/high-secure-data-hiding-using-cropping-image-and-least-significant-bit-steganography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44747.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">269</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">1691</span> Partially-Averaged Navier-Stokes for Computations of Flow Around Three-Dimensional Ahmed Bodies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Mirzaei">Maryam Mirzaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Sinisa%20Krajnovic%C2%B4"> Sinisa Krajnovic´ </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper reports a study about the prediction of flows around simplified vehicles using Partially-Averaged Navier-Stokes (PANS).

A comparison of the resolved and modeled physical flow scales is made with corresponding LES and experimental data for a better understanding of the performance of the PANS model. The PANS model is compared for coarse and fine grid resolutions and it is indicated that even a coarse-grid PANS simulation is able to produce fairly close flow predictions to those from a well-resolved LES simulation.

Thermal comfort realization in a residential building during such climate becomes more difficult regarding the phenomena of climate change, and the use of building and construction materials which have the feature of heat conduction as (bricks-reinforced concrete) and the global energy crises. For that, this study aims to how to realize internal thermal comfort through how to make the best use of building services (temporarily used service spaces) for reducing the electrical energy transfer and saving self-shading. In addition, the possibility of reduction traditional energy (fossil fuel) consumed in cooling through the use of building services for reducing the internal thermal comfort and the relationship between them. This study is based on measuring the consumed electrical energy rate in cooling (by using Design-Builder program) for a residential building (the place of study is: Egypt- Suez Canal- Suez City), this design model has lots of alternatives designs for the place of building services (center of building- the eastern front- southeastern front- the southern front- the south-west front, the western front). The building services are placed on the fronts with different rates for determining the best rate on fronts which realizes thermal comfort with the lowest of energy consumption used in cooling. Findings of the study indicate to that the best position for building services is on the west front then the south-west front, and the more the building services increase, the more energy consumption used in cooling of residential building decreases. Recommendations indicate to the need to study the building services positions in the new projects progress to select the best alternatives to realize ‘Energy conservation’ used in cooling or heating into the buildings in general, residential buildings particularly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=residential%20buildings" title="residential buildings">residential buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20conservation" title=" energy conservation"> energy conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20services" title=" building services"> building services</a>, <a href="https://publications.waset.org/abstracts/search?q=temporary%20used%20service%20spaces" title=" temporary used service spaces"> temporary used service spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=DesignBuilder" title=" DesignBuilder"> DesignBuilder</a> </p> <a href="https://publications.waset.org/abstracts/88067/the-role-of-building-services-in-energy-conservation-into-residential-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88067.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">294</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">1689</span> The Effect of Combustion Chamber Deposits (CCD) on Homogeneous Change Compression Ignition (HCCI)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulmagid%20A.%20Khattabi">Abdulmagid A.

In order to do this, two main objectives must first be met; tracking deposit formation trends in an HCCI engine and determining the sensitivity of HCCI combustion to CCD. This requires testing that demonstrates the differences in combustion between a clean engine and one with deposits coating the chamber. This will involve a long-term test that tracks the effects of CCD on combustion. The test will start with a clean engine. One baseline HCCI operating point is maintained for the duration of the test during which gradual combustion chamber deposit formation will occur. Combustion parameters, including heat release rates and emissions will be tracked for the duration and compared to the case of a clean engine. This work will begin by detailing the specifics of the test procedure and measurements taken throughout the test. Then a review of the effects of the gradual formation of deposits in the engine will be given. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fuels" title="fuels">fuels</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20atomization" title=" fuel atomization"> fuel atomization</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20factor" title=" pattern factor"> pattern factor</a>, <a href="https://publications.waset.org/abstracts/search?q=alternate%20fuels%20combustion" title=" alternate fuels combustion"> alternate fuels combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency%20gas%20turbine%20combustion" title=" efficiency gas turbine combustion"> efficiency gas turbine combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20blow%20out" title=" lean blow out"> lean blow out</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust%20and%20liner%20wall%20temperature" title=" exhaust and liner wall temperature"> exhaust and liner wall temperature</a> </p> <a href="https://publications.waset.org/abstracts/13801/the-effect-of-combustion-chamber-deposits-ccd-on-homogeneous-change-compression-ignition-hcci" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13801.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">527</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">1688</span> Experimental Study of LPG Diffusion Flame at Elevated Preheated Air Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20A.%20El-Kafy%20Amer">Ahmed A.

The flame is stabilized in a vertical water-cooled combustor by using air swirler. An experimental test rig was designed to investigate the different operating conditions. The burner head is designed so that the LPG fuel issued centrally and surrounded by the swirling air issues from an air swirler. There are three air swirlers having the same dimensions but having different blade angles to give different swirl numbers of 0.5, 0.87 and 1.5. The combustion air was heated electrically before entering the combustor up to a temperature about 500 K. Three air to fuel mass ratios of 30, 40 and 50 were also studied. The effect of air preheated temperature, swirl number and air to fuel mass ratios on the temperature maps, visible flame length, high temperature region (size) and exhaust species concentrations are studied. Some results show that as the air preheated temperature increases, the volume of high temperature region also increased but the flame length decreased. Increasing the air preheated temperature, EINOx, EICO2 and EIO2 increased, while EICO decreased. Increasing the air preheated temperature from 300 to 500 K, for all air swirl numbers used, the highest increase in EINOx, EICO2 and EIO2 are 141, 4 and 65%, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20preheated%20temperature" title="air preheated temperature">air preheated temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20swirler" title=" air swirler"> air swirler</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20length" title=" flame length"> flame length</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20index" title=" emission index"> emission index</a> </p> <a href="https://publications.waset.org/abstracts/30998/experimental-study-of-lpg-diffusion-flame-at-elevated-preheated-air-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30998.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">480</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">1687</span> Fractional Order Sallen-Key Filters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Soltan">Ahmed Soltan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20G.%20Radwan"> Ahmed G.

Therefore, this study aims to understand how oil contamination affects the torsion behavior of model steel piles at different soil densities. This research is crucial for evaluating the structural integrity and stability of piles in oil-contaminated environments. Clean sand samples and heavy motor oil were mixed in amounts ranging from 0 to 6% of the soil's dry weight. The mixture was thoroughly mixed to ensure uniform distribution of the oil throughout the sandy soil for simulating the field conditions. In these investigations, the relative densities (Dr), pile slenderness ratio (Lp/Dp), oil content (O.C%), and contaminated sand layer thickness (LC) were all different. Also, the paper presents an analysis of piles that are loaded both vertically and torsionally. The findings demonstrated that the pre-applied torsion load led to a decrease in the vertical bearing ability of the pile. Also, at Dr = 80%, the ultimate vertical load under combined load at constant torsional load T = (1/3Tu, 2/3Tu, and Tu) in the cases of (Lc/Lp) = 0.5 and (Lp/Dp) =13.3 was found to be reduced by (1.48, 2.78, and 4.15%) less than piles under independent vertical load, respectively so it is crucial to consider the torsion load during pile design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=torsion-vertical%20load" title="torsion-vertical load">torsion-vertical load</a>, <a href="https://publications.waset.org/abstracts/search?q=oil-contaminated%20sand" title=" oil-contaminated sand"> oil-contaminated sand</a>, <a href="https://publications.waset.org/abstracts/search?q=twist%20angle" title=" twist angle"> twist angle</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20pile" title=" steel pile"> steel pile</a> </p> <a href="https://publications.waset.org/abstracts/180837/experimental-studies-of-the-response-of-single-piles-under-torsional-and-vertical-combined-loads-in-contaminated-sand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180837.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">1684</span> Cardiac Protective Effect of Olive Oil against Ischemia Reperfusion- Induced Cardiac Arrhythmias in Isolated Diabetic Rat Hearts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ishfaq%20A.%20Bukhari">Ishfaq A.

Olive oil is rich in monounsaturated fatty acids, and has been reported for variety of beneficial cardiovascular effects including blood pressure lowering, anti-platelet, anti-diabetic and anti-inflammatory effects. Growing number evidences from preclinical and clinical studies have shown that olive oil improves insulin resistance, decrease vessels stiffness and prevent thromboembolism. We evaluated the effects of olive against streptozotocin-induced physiological disorders in the animal models of diabetes and ischemia and reperfusion (I/R)- induced cardiac arrhythmias. Diabetes was induced in male rats with a single intraperitoneal injection of streptozotocin (60 mg/kg), rats were treated for two months with olive oil (1 ml/kg p.o). Control animals received saline. Blood glucose, body weight were monitored every 14 days. At the end of the treatment rats were sacrificed hearts were isolated for mounting on langedorff’s apparatus. The blood glucose and body weight was not significantly different in the control and olive treated animals. The control diabetic animals exhibited 100% incidence of I/R –induced ventricular fibrillation which was reduced to 0% with olive oil, treatment. The duration of ventricular fibrillation reduced from 98.8± 2.3 (control) to 0 seconds in the olive oil treated group. Diltiazem, a calcium channel blocker (1 µm/L) showed similar results and protected the I/R-induced cardiac disorders. The biochemical analysis of the cardiac tissues showed that diabetes and I/R produce marked pathological changes in the cardiomyocytes including decreased glutathione (GSH) and increased oxidative stress (Malondialdehyde; MDA). Pretreatment of animals with olive oil (1 ml/kg p.o) increased GSH and MDA levels. Olive oil also improved the diabetic-induced histopathological changes in the cardiomyocytes. These finding indicates that olive possesses cardiac protective properties. Further studies are under way in our lab to explore the mechanism of the cardio-protective effect of olive oil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabeties" title="diabeties">diabeties</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia-reperfusion" title=" ischemia-reperfusion"> ischemia-reperfusion</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20oil" title=" olive oil"> olive oil</a>, <a href="https://publications.waset.org/abstracts/search?q=rats%20heart" title=" rats heart"> rats heart</a> </p> <a href="https://publications.waset.org/abstracts/33792/cardiac-protective-effect-of-olive-oil-against-ischemia-reperfusion-induced-cardiac-arrhythmias-in-isolated-diabetic-rat-hearts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33792.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">1683</span> Evaluation of Greenhouse Covering Materials </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mouustafa%20A.%20Fadel">Mouustafa A.

In hot areas, balancing between inside and outside the greenhouse consumes most of the energy spent in production systems. In this research, a special testing apparatus was fabricated to simulate the structure of the greenhouse provided with a 400W full spectrum light. Tests were carried out to investigate the effectiveness of different commercial covering material in light and heat diffusion. Twenty one combinations of Fiberglass, Polyethylene, Polycarbonate, Plexiglass and Agril (PP nonwoven fabric) were tested. It was concluded that Plexiglass was the highest in light transparency of 87.4% where the lowest was 33% and 86.8% for Polycarbonate sheets. The enthalpy of the air moving through the testing rig was calculated according to air temperature differences between inlet and outlet openings. The highest enthalpy value was for one layer of Fiberglass and it was 0.81 kj/kg air while it was for both Plexiglass and blocked Fiberglass with a value of 0.5 kj/kg air. It is concluded that, although Plexiglass has high level of transparency which is indeed very helpful under low levels of solar flux, it is not recommended under hot arid conditions where solar flux is available most of the year. On the other hand, it might be a disadvantage to use Plixeglass specially in summer where it helps to accumulate more heat inside the greenhouse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=greenhouse" title="greenhouse">greenhouse</a>, <a href="https://publications.waset.org/abstracts/search?q=covering%20materials" title=" covering materials"> covering materials</a>, <a href="https://publications.waset.org/abstracts/search?q=aridlands" title=" aridlands"> aridlands</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20control" title=" environmental control"> environmental control</a> </p> <a href="https://publications.waset.org/abstracts/22375/evaluation-of-greenhouse-covering-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22375.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">477</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">1682</span> Monitoring Public Transportation in Developing Countries Using Automatic Vehicle Location System: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Osama">Ahmed Osama</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20A.%20Mahdy"> Hassan A.

Cairo public bus service suffers from several problems such as unscheduled stops, unscheduled route deviations, and inaccurate schedules, which have negative impacts on service reliability. This research aims to study those problems for a selected bus route in Cairo using a prototype AVL system. Experimental trips were run on the selected route; and the locations of unscheduled stops, regions of unscheduled deviations, along with other trip time and speed data were collected. Data was analyzed to demonstrate the reliability of passengers on the unscheduled stops compared to the scheduled ones. Trip time was also modeled to assess the unscheduled stops’ impact on trip time, and to check the accuracy of the applied scheduled trip time. Moreover, frequency and length of the unscheduled route deviations, as well as their impact on the bus stops, were illustrated. Solutions were proposed for the bus service deficiencies using the AVL system. Finally, recommendations were proposed for further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automatic%20vehicle%20location" title="automatic vehicle location">automatic vehicle location</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transportation" title=" public transportation"> public transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=unscheduled%20stops" title=" unscheduled stops"> unscheduled stops</a>, <a href="https://publications.waset.org/abstracts/search?q=unscheduled%20route%20deviations" title=" unscheduled route deviations"> unscheduled route deviations</a>, <a href="https://publications.waset.org/abstracts/search?q=inaccurate%20schedule" title=" inaccurate schedule"> inaccurate schedule</a> </p> <a href="https://publications.waset.org/abstracts/38335/monitoring-public-transportation-in-developing-countries-using-automatic-vehicle-location-system-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38335.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">390</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">1681</span> Comparison between Hardy-Cross Method and Water Software to Solve a Pipe Networking Design Problem for a Small Town</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Emad%20Ahmed">Ahmed Emad Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeyad%20Ahmed%20Hussein"> Zeyad Ahmed Hussein</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salama%20Afifi"> Mohamed Salama Afifi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mohammed%20Eid"> Ahmed Mohammed Eid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water has a great importance in life. In order to deliver water from resources to the users, many procedures should be taken by the water engineers. One of the main procedures to deliver water to the community is by designing pressurizer pipe networks for water. The main aim of this work is to calculate the water demand of a small town and then design a simple water network to distribute water resources among the town with the smallest losses. Literature has been mentioned to cover the main point related to water distribution. Moreover, the methodology has introduced two approaches to solve the research problem, one by the iterative method of Hardy-cross and the other by water software Pipe Flow. The results have introduced two main designs to satisfy the same research requirements. Finally, the researchers have concluded that the use of water software provides more abilities and options for water engineers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=looping%20pipe%20networks" title="looping pipe networks">looping pipe networks</a>, <a href="https://publications.waset.org/abstracts/search?q=hardy%20cross%20networks%20accuracy" title=" hardy cross networks accuracy"> hardy cross networks accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20error%20of%20hardy%20cross%20method" title=" relative error of hardy cross method"> relative error of hardy cross method</a> </p> <a href="https://publications.waset.org/abstracts/156922/comparison-between-hardy-cross-method-and-water-software-to-solve-a-pipe-networking-design-problem-for-a-small-town" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156922.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">164</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">1680</span> Bayesian Approach for Moving Extremes Ranked Set Sampling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Said%20Ali%20Al-Hadhrami">Said Ali Al-Hadhrami</a>, <a href="https://publications.waset.org/abstracts/search?q=Amer%20Ibrahim%20Al-Omari"> Amer Ibrahim Al-Omari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, Bayesian estimation for the mean of exponential distribution is considered using Moving Extremes Ranked Set Sampling (MERSS).

The effect of doxorubicin (4 mg/kg b.w.week) without or with oral administration of ethanolic purslane (Portulaca oleracea) shoot (leaves and stems) extract (50 mg/kg b.w. day) or ethanolic purslane seeds extract (50 mg/kg b.w.day) co-treatments for 6 weeks was evaluated in adult male rats. Serum ALT, AST, ALP, GGT, total bilirubin, total protein, and albumin levels were assayed. Lipid peroxidation (indexed by MDA) and antioxidants like hepatic glutathine, glutathione transferase, peroxidase, SOD, and CAT were assessed. There was an increase in serum levels of ALT, AST, ALP, GGT and total bilirubin. In addition, hepatic glutathine, glutathione transferase, peroxidase, SOD, and CAT activities were decreased while lipid peroxidation in the liver was increased. Co-administration of ethanolic purslane and seed extracts successfully improved the adverse changes in the liver functions with an increase in antioxidants activities and reduction of lipid peroxidation. In conclusion, it can be supposed that dietary purslane extract supplementation may provide a cushion for a prolonged therapeutic option against DOX hepatopathy without harmful side effects. However, further clinical studies are required to assess the safety and efficacy of these extract in human beings. <p class="card-text"><strong>Keywords:</strong> <a
