Adel Edward Farid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The resistance of staphylococci to various antibiotics has become a major concern for health care professionals. The efficacy of the combinations of selected glycopeptides (vancomycin and teicoplanin) with gentamicin or rifampicin, as well as that of gentamicin/rifampicin combination, was studied against selected pathogenic staphylococcus isolated from Egypt. The molecular distribution of genes conferring resistance to these four antibiotics was detected among tested clinical isolates. Antibiotic combinations were studied using the checkerboard technique and the time-kill assay (in both the stationary and log phases). Induction of resistance to glycopeptides in staphylococci was tried in the absence and presence of diclofenac sodium as inducer. Transmission electron microscopy was used to study the effect of glycopeptides on the ultrastructure of the cell wall of staphylococci. Attempts were made to cure gentamicin resistance plasmids and to study the transfer of these plasmids by conjugation. Trials for the transformation of the successfully isolated gentamicin resistance plasmid to competent cells were carried out. The detection of genes conferring resistance to the tested antibiotics was performed using the polymerase chain reaction. The studied antibiotic combinations proved their efficacy, especially when tested during the log phase. Induction of resistance to glycopeptides in staphylococci was more promising in presence of diclofenac sodium, compared to its absence. Transmission electron microscopy revealed the thickening of bacterial cell wall in staphylococcus clinical isolates due to the presence of tested glycopeptides. Curing of gentamicin resistance plasmids was only successful in 2 out of 9 tested isolates, with a curing rate of 1 percent for each. Both isolates, when used as donors in conjugation experiments, yielded promising conjugation frequencies ranging between 5.4 X 10-2 and 7.48 X 10-2 colony forming unit/donor cells. Plasmid isolation was only successful in one out of the two tested isolates. However, low transformation efficiency (59.7 transformants/microgram plasmid DNA) of such plasmids was obtained. Negative regulators of autolysis, such as arlR, lytR and lrgB, as well as cell-wall associated genes, such as pbp4 and/or pbp2, were detected in staphylococcus isolates with reduced susceptibility to the tested glycopeptides. Concerning rifampicin resistance genes, rpoBstaph was detected in 75 percent of the tested staphylococcus isolates. It could be concluded that in vitro studies emphasized the usefulness of the combination of vancomycin or teicoplanin with gentamicin or rifampicin, as well as that of gentamicin with rifampicin, against staphylococci showing varying resistance patterns. However, further in vivo studies are required to ensure the safety and efficacy of such combinations. Diclofenac sodium can act as an inducer of resistance to glycopeptides in staphylococci. Cell-wall thickness is a major contributor to such resistance among them. Gentamicin resistance in these strains could be chromosomally or plasmid mediated. Multiple mutations in the rpoB gene could mediate staphylococcus resistance to rifampicin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glycopeptides" title="glycopeptides">glycopeptides</a>, <a href="https://publications.waset.org/abstracts/search?q=combinations" title=" combinations"> combinations</a>, <a href="https://publications.waset.org/abstracts/search?q=induction" title=" induction"> induction</a>, <a href="https://publications.waset.org/abstracts/search?q=diclofenac" title=" diclofenac"> diclofenac</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20electron%20microscopy" title=" transmission electron microscopy"> transmission electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=polymerase%20chain%20reaction" title=" polymerase chain reaction"> polymerase chain reaction</a> </p> <a href="https://publications.waset.org/abstracts/3949/antimicrobial-efficacy-of-some-antibiotics-combinations-tested-against-some-molecular-characterized-multiresistant-staphylococcus-clinical-isolates-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3949.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">81</span> Electrical Investigations of Polyaniline/Graphitic Carbon Nitride Composites Using Broadband Dielectric Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20A.%20Moussa">M.

In this paper, we develop an Avatar based system to teach computer programming to deaf and hearing-impaired students using Arabic Signed language with new signs vocabulary that is been developed for computer programming education. The system is tested on a number of high school students and results showed the importance of visualization in increasing the comprehension or understanding of concepts for deaf students through the avatar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hearing-impaired%20students" title="hearing-impaired students">hearing-impaired students</a>, <a href="https://publications.waset.org/abstracts/search?q=isolation" title=" isolation"> isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=self-esteem" title=" self-esteem"> self-esteem</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20difficulties" title=" learning difficulties"> learning difficulties</a> </p> <a href="https://publications.waset.org/abstracts/101136/learning-programming-for-hearing-impaired-students-via-an-avatar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101136.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">145</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">73</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">72</span> Release of Calcein from Liposomes Using Low and High Frequency Ultrasound</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghaleb%20A.%20Husseini">Ghaleb A.

Pegylated liposomes were used to encapsulate calcein and then release this model drug when 20-kHz, 40-kHz, 1-MHz and 3-MHz ultrasound were applied at different acoustic power densities. Fluorescence techniques were then used to measure the percent drug release of calcein from these targeted liposomes. Results showed that as the power density increases, at the four frequencies studied, the release of calcein also increased.

To understand the dynamics between these two concepts, various principles are adopted, from the right to development to development-based human rights. Despite the initiatives taken, the relationship between development and human rights remains unclear. However, the overlap between these two views and the idea that efforts should be made in the field of human rights have increased in recent years. It is then evaluated whether the right to sustainable development is acceptable or not. The article concludes that the principles of sustainable development are directly or indirectly recognized in various human rights instruments, which is a good answer to the question posed above. This book therefore cites regional and international human rights agreements such as , as well as the jurisprudence and interpretative guidelines of human rights institutions, to prove this hypothesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title="sustainable development">sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20right%20to%20development" title=" the right to development"> the right to development</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20human%20rights-based%20approach%20to%20development" title=" the human rights-based approach to development"> the human rights-based approach to development</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20rights" title=" environmental rights"> environmental rights</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20development" title=" economic development"> economic development</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20sustainability%20human%20rights%20protection" title=" social sustainability human rights protection"> social sustainability human rights protection</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights%20violations" title=" human rights violations"> human rights violations</a>, <a href="https://publications.waset.org/abstracts/search?q=workers%E2%80%99%20rights" title=" workers’ rights"> workers’ rights</a>, <a href="https://publications.waset.org/abstracts/search?q=justice" title=" justice"> justice</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a> </p> <a href="https://publications.waset.org/abstracts/187438/the-impact-of-artificial-intelligence-on-human-developments-obligations-and-theories" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187438.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">37</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> Extraction and Identification of Natural Antioxidants from Liquorices (Glycyrrhiza glabra) and Carob (Ceratonia siliqua) and Its Application in El-Mewled El-Nabawy Sweets (Sesames and Folia)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mervet%20A.%20El-sherif">Mervet A.

Besides, their effects as powder and antioxidant extracts addition on refined sunflower oil stability as natural antioxidants were evaluated. Total polyphenol contents as total phenols, total carotenoids and total tannins were 353.93mg/100g (gallic acid), 10.62mg/100g (carotenoids) and 83.33mg/100g (tannic acid), respectively in licorice, while in carob, it was 186.07, 18.66 and 106.67, respectively. Polyphenol compounds of the studied licorice and carob extracts were determined and identified by HPLC. The stability of refined sunflower oil (which determined by peroxide value and Rancimat) was increased with increasing the level of polyphenols extracts addition. Also, our study shows the effect of addition of these polyphenols extracts to El-mewled El-nabawy sweets fortified by full cream milk powder (sesames and folia). We found that, licorice and carob as powder and polyphenols extracts were delayed the rancidity of sesame and peanut significantly. That encourages using licorice and carob as powder and polyphenols extracts as a good natural antioxidants source instead of synthetic antioxidants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=licorice" title="licorice">licorice</a>, <a href="https://publications.waset.org/abstracts/search?q=carob" title=" carob"> carob</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20antioxidants" title=" natural antioxidants"> natural antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=applications" title=" applications"> applications</a> </p> <a href="https://publications.waset.org/abstracts/8512/extraction-and-identification-of-natural-antioxidants-from-liquorices-glycyrrhiza-glabra-and-carob-ceratonia-siliqua-and-its-application-in-el-mewled-el-nabawy-sweets-sesames-and-folia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8512.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">436</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> Nature of Maritime Dispute Resolution by Arbitration: USA as a Reference Point</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thusitha%20B.%20Abeysekara">Thusitha B.

In doing so, the research aims to analyse the relevant legal principles in the context of current maritime arbitration practices in selected jurisdictions. The research also aims to analyse the advantages and applicability of arbitration in maritime dispute settlements over the litigation and further approaches the role of specialist maritime arbitration institutes in the USA and the position of international merchant organizations in maritime arbitration. Further, research values the legislative aspects of maritime arbitration. The study would evaluate the contemporary issues in maritime arbitration practices in the USA and further analyses the statistical information on maritime arbitration. Finally, the research made remarks to often parallel consequence in USA legal systems in maritime arbitration and despite the fundamental divergences of the applicable principles and practices of maritime arbitration. The research finally suggests the doctrine should reshape with equitable remedies and international maritime arbitration practices with its institutional impact rather than using as statutory rules related maritime arbitration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arbitration" title="arbitration">arbitration</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20shipping" title=" international shipping"> international shipping</a>, <a href="https://publications.waset.org/abstracts/search?q=maritime%20dispute" title=" maritime dispute"> maritime dispute</a>, <a href="https://publications.waset.org/abstracts/search?q=New%20York%20convention" title=" New York convention"> New York convention</a> </p> <a href="https://publications.waset.org/abstracts/77152/nature-of-maritime-dispute-resolution-by-arbitration-usa-as-a-reference-point" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77152.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">221</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> Modeling and Simulations of Surface Plasmon Waveguide Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moussa%20Hamdan">Moussa Hamdan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulati%20Abdullah"> Abdulati Abdullah </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an investigation of the fabrication of the optical devices in terms of their characteristics based on the use of the electromagnetic waves.

The high model complexity of ANNs along with the model-free nature of RL algorithms provides a desirable combination for many robotics applications. There is a huge need for algorithms that generalize using raw sensory inputs, such as vision, without any hand-engineered features or domain heuristics. In this paper, the standard control problem of line following robot was used as a test-bed, and an ANN controller for the robot was trained on images from a live video feed using Q-learning. A virtual agent was first trained in simulation environment and then deployed onto a robot’s hardware. The robot successfully learns to traverse a wide range of curves and displays excellent generalization ability. Qualitative analysis of the evolution of policies, performance and weights of the network provide insights into the nature and convergence of the learning algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title="artificial neural networks">artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=q-learning" title=" q-learning"> q-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20learning" title=" reinforcement learning"> reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=robot%20learning" title=" robot learning"> robot learning</a> </p> <a href="https://publications.waset.org/abstracts/70136/analysis-of-q-learning-on-artificial-neural-networks-for-robot-control-using-live-video-feed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70136.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Forced Vibration of a Planar Curved Beam on Pasternak Foundation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akif%20Kutlu">Akif Kutlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Merve%20Ermis"> Merve Ermis</a>, <a href="https://publications.waset.org/abstracts/search?q=Nihal%20Eratl%C4%B1"> Nihal Eratlı</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20H.%20Omurtag"> Mehmet H.

Problems are solved by using the mixed finite element formulation. Element matrices based on Timoshenko beam theory are employed. The finite element matrices are derived by directly inserting the analytical expressions (arc length, curvature, and torsion) defining helix geometry into the formulation. Helicoidal rod domain is discretized by a two-noded curvilinear element. Each node of the element has 12 DOFs, namely, three translations, three rotations, two shear forces, one axial force, two bending moments and one torque. A parametric study is performed to investigate the influence of elliptical cross sectional geometry and its orientation over the natural frequencies of the conical type helicoidal rod. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conical%20helix" title="conical helix">conical helix</a>, <a href="https://publications.waset.org/abstracts/search?q=elliptical%20cross%20section" title=" elliptical cross section"> elliptical cross section</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title=" free vibration"> free vibration</a> </p> <a href="https://publications.waset.org/abstracts/49017/free-vibration-analysis-of-conical-helicoidal-rods-having-elliptical-cross-sections-positioned-in-different-orientation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49017.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">315</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> Amelioration of Over-Expression of bax, Nrf2 and NFК–β in Nano-Sized Titanium Dioxide-Intoxicated Mice by Potent Antioxidants </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Z.%20Rizk">Maha Z.

The objective of this study is investigating either the effect of individual or combined doses of idebenone, carnosine and vitamin E on amelioration of some biochemical indices of nano sized titanium dioxide (TiO2 NPS) induced metabolic disorders in mice liver. TiO2-NPS was administered in an oral dose of 150 mg/kg for consecutive 14 days followed by oral daily doses of the aforementioned antioxidants for 1 month. TiO2-NPS induced a significant elevation in serum level of ALT and AST, hepatic inflammatory markers (tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)) and increased the percent of DNA damage which was assessed by COMET assay in addition to the apoptotic marker Caspase-3. Moreover, mRNA gene expression observed by RT-PCR showed a significant overexpression in nuclear factor relation-2 (Nrf2), nuclear factor kappa beta (NF-Kβ) and the apoptotic factor (bax), and a significant down-regulation in the antiapoptotic factor (bcl2) level. In conclusion, idebenone, carnosine and vitamin E ameliorated the deviated parameters with a variable degree with the most pronounced role in alleviating the hazardous effect of TiO2 NPS toxicity following the combination regimen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=idebenone" title="idebenone">idebenone</a>, <a href="https://publications.waset.org/abstracts/search?q=carnosine" title=" carnosine"> carnosine</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20E" title=" vitamin E"> vitamin E</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO2%20NPS" title=" TiO2 NPS"> TiO2 NPS</a>, <a href="https://publications.waset.org/abstracts/search?q=caspase-3" title=" caspase-3"> caspase-3</a>, <a href="https://publications.waset.org/abstracts/search?q=NrF2" title=" NrF2"> NrF2</a>, <a href="https://publications.waset.org/abstracts/search?q=NF-KB" title=" NF-KB"> NF-KB</a> </p> <a href="https://publications.waset.org/abstracts/7223/amelioration-of-over-expression-of-bax-nrf2-and-nfk-v-in-nano-sized-titanium-dioxide-intoxicated-mice-by-potent-antioxidants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7223.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">386</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">63</span> Simulating Lean and Green Correlation in Supply Chain Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Benmoussa">Rachid Benmoussa</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Ezzahra%20Essaber"> Fatima Ezzahra Essaber</a>, <a href="https://publications.waset.org/abstracts/search?q=Roland%20De%20Guio"> Roland De Guio</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Zahra%20Ben%20Moussa"> Fatima Zahra Ben Moussa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Implementing green practices in supply chain management is a complex task mainly because ecological, economical and operational goals are usually in conflict. Green practices might thus face companies’ reluctance because managers can consider its implementation obviously as a performance lean degradation. To implement lean and green practices successfully, companies need relevant decision-making tools to highlight the correlation between them. To contribute to this issue, this work tries to answer the following research question: How to use simulation to assess correlation (antagonism or convergence) between lean and green goals? To answer this question, we propose in this paper a based simulation process that measures correlation generally between two variables. So as to prove its relevance, a logistics academic case study is used to illustrate all its stages. It shows, as for example, that Lean goal 'Stock' and Green goal 'CO₂ emission' are not conceptually correlated (linearly). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=simulation" title="simulation">simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=lean" title=" lean"> lean</a>, <a href="https://publications.waset.org/abstracts/search?q=green" title=" green"> green</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a> </p> <a href="https://publications.waset.org/abstracts/92960/simulating-lean-and-green-correlation-in-supply-chain-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92960.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">500</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">62</span> Estimation of Stress-Strength Parameter for Burr Type XII Distribution Based on Progressive Type-II Censoring</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20Abd-Elfattah">A.

Instance-based ontology alignment is based on the comparison of the extensions of concepts; and represents a very promising technique to find semantic correspondences between entities of different ontologies. In practice, two situations may arise: ontologies that share many common instances and ontologies that share few or do not share common instances. In this paper, we describe an approach to manage the latter case. This approach exploits the reasoning on ontologies in order to create a corpus of common instances. We show that it is theoretically powerful because it is based on description logics and very useful in practice. We present the experimental results obtained by running our approach on ontologies of OAEI 2012 benchmark test. The results show the performance of our approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=description%20logic%20inference" title="description logic inference">description logic inference</a>, <a href="https://publications.waset.org/abstracts/search?q=instance-based%20ontology%20alignment" title=" instance-based ontology alignment"> instance-based ontology alignment</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20interoperability" title=" semantic interoperability"> semantic interoperability</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20web" title=" semantic web"> semantic web</a> </p> <a href="https://publications.waset.org/abstracts/6254/combining-instance-based-and-reasoning-based-approaches-for-ontology-matching" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6254.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">447</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Sundarban as a Buffer against Storm Surge Flooding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohiuddin%20Sakib">Mohiuddin Sakib</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatin%20Nihal"> Fatin Nihal</a>, <a href="https://publications.waset.org/abstracts/search?q=Anisul%20Haque"> Anisul Haque</a>, <a href="https://publications.waset.org/abstracts/search?q=Munsur%20Rahman"> Munsur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansur%20Ali"> Mansur Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sundarban, the largest mangrove forest in the world, is known to act as a buffer against the cyclone and storm surge. Theoretically, Sundarban absorbs the initial thrust of the wind and acts to ‘resist’ the storm surge flooding. The role of Sundarban was evident during the cyclone Sidr when the Sundarban solely defended the initial thrust of the cyclonic wind and the resulting storm surge inundation. In doing this, Sundarban sacrificed 30% of its plant habitats. Although no scientific study has yet been conducted, it is generally believed that Sundarban will continuously play its role as a buffer against the cyclone when landfall of the cyclone is at or close to the Sundarban. Considering these facts, the present study mainly focused on a scientific insight into the role of Sundarban as a buffer against the present-day cyclone and storm surge and also its probable role on the impacts of future storms of similar nature but with different landfall locations. The Delft 3D dashboard and flow model are applied to compute the resulting inundation due to cyclone induced storm surge. The results show that Sundarban indeed acts as a buffer against the storm surge inundation when cyclone landfall is at or close to Sundarban. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffer" title="buffer">buffer</a>, <a href="https://publications.waset.org/abstracts/search?q=Mangrove%20forest" title=" Mangrove forest"> Mangrove forest</a>, <a href="https://publications.waset.org/abstracts/search?q=Sidr" title=" Sidr"> Sidr</a>, <a href="https://publications.waset.org/abstracts/search?q=landfall" title=" landfall"> landfall</a>, <a href="https://publications.waset.org/abstracts/search?q=roughness" title=" roughness"> roughness</a> </p> <a href="https://publications.waset.org/abstracts/37352/sundarban-as-a-buffer-against-storm-surge-flooding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37352.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">394</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">59</span> Comparison of User Experience in VR When Hand Gestures Are Used vs. Using Controller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanu%20Muhammed%20C.">Sanu Muhammed C.</a>, <a href="https://publications.waset.org/abstracts/search?q=Nihal%20Vadakkan"> Nihal Vadakkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahil%20Athrij"> Sahil Athrij</a>, <a href="https://publications.waset.org/abstracts/search?q=Sasi%20Gopalan"> Sasi Gopalan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, the content entertainment industry is dominated by mobile devices. As the trends slowly shift towards AR/VR applications, the user experience on these devices should be considered, and we are trying to improve user experience in VR. This paper proposes a survey-based solution to improve user experience in VR. By creating a VR environment where users can move a ball from one position to another using a remote controller and another VR environment where users can move a ball from one place to another using hand gestures/ By allowing a set of audience to use these two environments, we can get their feedback. There are two steps in this comparison, 1) Using Hand Gestures To Move Ball In VR Environment: Here, we create a VR environment where two baskets are there, and one ball will be there in a basket. Here users can transfer the ball to another basket using hand gestures. They will be able to move the ball using hand gestures. 2) Using Remote Control To Move Ball In VR Environment: Here, we create a VR environment where two baskets are there, and one ball will be there in a basket. Here users can transfer the ball to another basket using a remote control. They will be able to move the ball using a remote controller. The above two environments are given to users to experience, and their responses will be recorded to compare the user experience in the above two environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title="virtual reality">virtual reality</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20experience" title=" user experience"> user experience</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20gestures" title=" hand gestures"> hand gestures</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20control" title=" remote control"> remote control</a> </p> <a href="https://publications.waset.org/abstracts/159470/comparison-of-user-experience-in-vr-when-hand-gestures-are-used-vs-using-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159470.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">146</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> Vehicle Type Classification with Geometric and Appearance Attributes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20S.%20Moussa">Ghada S.

This fact brings a growing need for efficiently yet effectively classifying vehicles into their corresponding categories, which play a crucial role in many areas of infrastructure planning and traffic management. This paper presents two vehicle-type classification approaches; 1) geometric-based and 2) appearance-based. The two classification approaches are used for two tasks: multi-class and intra-class vehicle classifications. For the evaluation purpose of the proposed classification approaches’ performance and the identification of the most effective yet efficient one, 10-fold cross-validation technique is used with a large dataset. The proposed approaches are distinguishable from previous research on vehicle classification in which: i) they consider both geometric and appearance attributes of vehicles, and ii) they perform remarkably well in both multi-class and intra-class vehicle classification.

Classification of vehicle images is facing several problems such as: high intra-class vehicle variations, occlusion, shadow, illumination. These problems and others must be considered to develop a reliable vehicle classification system. In this study, a reliable multi-type vehicle classification system based on Bag-of-Words (BoW) paradigm is developed. Our proposed system used and compared four well-known classifiers; Linear Discriminant Analysis (LDA), Support Vector Machine (SVM), k-Nearest Neighbour (KNN), and Decision Tree to classify vehicles into four categories: motorcycles, small, medium and large. Experiments on a large dataset show that our approach is efficient and reliable in classifying vehicles with accuracy of 95.7%. The SVM outperforms other classification algorithms in terms of both accuracy and robustness alongside considerable reduction in execution time. The innovativeness of developed system is it can serve as a framework for many vehicle classification systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicle%20classification" title="vehicle classification">vehicle classification</a>, <a href="https://publications.waset.org/abstracts/search?q=bag-of-words%20technique" title=" bag-of-words technique"> bag-of-words technique</a>, <a href="https://publications.waset.org/abstracts/search?q=SVM%20classifier" title=" SVM classifier"> SVM classifier</a>, <a href="https://publications.waset.org/abstracts/search?q=LDA%20classifier" title=" LDA classifier"> LDA classifier</a>, <a href="https://publications.waset.org/abstracts/search?q=KNN%20classifier" title=" KNN classifier"> KNN classifier</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20tree%20classifier" title=" decision tree classifier"> decision tree classifier</a>, <a href="https://publications.waset.org/abstracts/search?q=SIFT%20algorithm" title=" SIFT algorithm"> SIFT algorithm</a> </p> <a href="https://publications.waset.org/abstracts/7262/a-reliable-multi-type-vehicle-classification-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7262.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">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Synthesis, Spectroscopic and XRD Study of Transition Metal Complex Derived from Low-Schiff Acyl-Hydrazone Ligand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamedou%20El%20Boukhary">Mohamedou El Boukhary</a>, <a href="https://publications.waset.org/abstracts/search?q=Farba%20Bouyagui%20Tamboura"> Farba Bouyagui Tamboura</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Hamady%20Barry"> A.

They are studied for their antioxidant, antibacterial and antiviral properties. The complexes of transition metals and the lanthanide they derive are well known for their magnetic, optical, and catalytic properties. In this work, we present the synthesis of an acyl-hydrazone (H2L) schiff base and their 3d transition complexes. The ligand (H2L) is characterized by IR, NMR (1H; 13C) spectroscopy. The complexes are characterized by different physic-chemical techniques such as IR, UV-visible, conductivity, measurement of magnetic susceptibility. The study of XRD allowed us to elucidate the crystalline structure of the manganese (Mn) complex. The asymmetric unit of the complex is composed of two molecules of the ligand, one manganese (II) ion, and two coordinate chloride ions; the environment around Mn is described as a pentagonal base bipyramid. In the crystal lattice, the asymmetric unit is bound by hydrogen bonds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synthene" title="synthene">synthene</a>, <a href="https://publications.waset.org/abstracts/search?q=acyl-hydrazone" title=" acyl-hydrazone"> acyl-hydrazone</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20transition%20metal%20complex" title=" 3D transition metal complex"> 3D transition metal complex</a>, <a href="https://publications.waset.org/abstracts/search?q=application" title=" application"> application</a> </p> <a href="https://publications.waset.org/abstracts/186028/synthesis-spectroscopic-and-xrd-study-of-transition-metal-complex-derived-from-low-schiff-acyl-hydrazone-ligand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186028.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">55</span> Evaluation of Microleakage of a New Generation Nano-Ionomer in Class II Restoration of Primary Molars </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Salem">Ghada Salem</a>, <a href="https://publications.waset.org/abstracts/search?q=Nihal%20Kabel"> Nihal Kabel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: This <em>in vitro</em> study was carried out to assess the microleakage properties of nano-filled glass ionomer in comparison to resin-reinforced glass ionomers.

Results: Two way ANOVA test revealed a statistically significant lower degree of microleakage in both occlusal and gingival restorations (0.4±0.2), (0.9±0.1) for nano-filled glass ionomer group in comparison to resin modified glass ionomer (2.3±0.7), (2.4±0.5). No statistical difference was found between gingival and occlusal leakage regarding the effect of the measured site. Conclusion: Nano-filled glass ionomer shows superior sealing ability which enables this type of restoration to be used in minimum invasive treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microleakage" title="microleakage">microleakage</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoionomer" title=" nanoionomer"> nanoionomer</a>, <a href="https://publications.waset.org/abstracts/search?q=resin-reinforced%20glass%20ionomer" title=" resin-reinforced glass ionomer"> resin-reinforced glass ionomer</a>, <a href="https://publications.waset.org/abstracts/search?q=proximal%20cavity%20preparation" title=" proximal cavity preparation"> proximal cavity preparation</a> </p> <a href="https://publications.waset.org/abstracts/61113/evaluation-of-microleakage-of-a-new-generation-nano-ionomer-in-class-ii-restoration-of-primary-molars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61113.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">235</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> Various Factors Affecting Students Performances In A Saudi Medical School</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raneem%20O.%20Salem">Raneem O.

The objective of this study is to identify these factors and correlate them to the GPA of the students. Methods: A cross-sectional study design utilizing grade point averages (GPAs) of two cohorts of students in both levels of the pre-clinical phase. In addition, self-administered questionnaire was used to evaluate the effect of these factors on students with poor and good cumulative GPA. Results: Among the various factors studied, gender, marital status, and the transportation used to reach the faculty significantly affected academic performance of students. Students with a cumulative GPA of 3.0 or greater significantly differed than those with a GPA of less than 3.0 being higher in female students, in married students, and type of transportation used to reach the college. Factors including age, educational factors, and type of transportation used have shown to create a significant difference in GPA between male and females. Conclusion: Factors such as age, gender, marital status, learning resources, study time, and the transportation used have been shown to significantly affect medical student GPA as a whole batch as well as when they are tested for gender. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20performance" title="academic performance">academic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20factors" title=" educational factors"> educational factors</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20resources" title=" learning resources"> learning resources</a>, <a href="https://publications.waset.org/abstracts/search?q=study%20time" title=" study time"> study time</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-demographic%20factors" title=" socio-demographic factors"> socio-demographic factors</a> </p> <a href="https://publications.waset.org/abstracts/1589/various-factors-affecting-students-performances-in-a-saudi-medical-school" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1589.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">275</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> Tajwīd and Mawwāl Toward Khushūʿ in Islam and Tarab in Arab Music: Common Musical Elements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Moussa%20Khalaf">Mohammad Moussa Khalaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a significant term in Arab music, ṭarab identifies a particular expression of feelings and emotions, especially in the vocal practice of Arab music. Ṭarab aims to take both the performer and the audience from a normal feeling state to a new state of spiritual feeling through the art of mawwāl. Because of the expertise required for mawwāl, the ability to reach ṭarab has long been considered an indication that a musician has reached a high musical level. Another significant Islamic concept related to feelings and emotions is khushūʿ. It is known that one of the ways to get Khāsheʿ (humble to God) is the artistic reading of the holy Qur’ān. The artistic recitation of the Qur’ān is tajwīd. Like mawwāl, tajwīd requires a high-level rendition to lead the listener to the special emotional state. The research will focus on the relationships between ṭarab, khushūʿ, tajwīd, and mawwāl in Islamic-Arab culture in a way that has not been addressed previously. The relationships between tajwid and mawwāl, ṭarab and khushūʿ would be identified through the examination of musical factors, socio-cultural factors, and emotional factors. <p
