is a relapsing–remitting inflammatory bowel disease with a progressive course. The aim of our study was to evaluate the relationship between the immunomarkers: Nitric Oxide (NO), pro-inflammatory cytokines, and blood count-based ratios and the outcome of corticosteroid or anti-TNF-α therapy in patients with complicated Crohn’s Disease. In this context, we evaluated the NLR as the ratio of neutrophil count to lymphocyte count, PLR as the ratio of platelet counts to lymphocyte count, and MLR as the ratio of monocyte count to lymphocyte count in patients and controls. Furthermore, we assessed NO production by the Griess method in plasma along with iNOS and NF-κB expression by immunofluorescence method in intestinal tissues of patients and controls. In the same way, we evaluated plasma TNF-α, IL-17A, and IL-10 levels using ELISA. Our results indicate that blood count-based ratios NLR, PLR, and MLR were significantly higher in patients compared to controls. In addition, increased systemic levels of NO, TNF-α, and IL-17A and colonic expression of iNOS and NF-κB were observed in the same patients. Interestingly, the high ratio of NLR and MLR, as well as NO production, was significantly decreased in treated patients. Collectively, our findings suggest that Nitric Oxide, as well as the blood count-based ratios (NLR, PLR, MLR), could constitute useful immuno-markers in complicated Crohn’s Disease, predicting the response to treatment <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complicated%20crohn%E2%80%99s%20disease" title="complicated crohn’s disease">complicated crohn’s disease</a>, <a href="https://publications.waset.org/abstracts/search?q=nitric%20oxide" title=" nitric oxide"> nitric oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20count-based%20ratios" title=" blood count-based ratios"> blood count-based ratios</a>, <a href="https://publications.waset.org/abstracts/search?q=treatments" title=" treatments"> treatments</a>, <a href="https://publications.waset.org/abstracts/search?q=pro-inflammatory%20cytokines" title=" pro-inflammatory cytokines"> pro-inflammatory cytokines</a> </p> <a href="https://publications.waset.org/abstracts/168994/nitric-oxide-and-blood-based-ratios-as-promising-immuno-markers-in-patients-with-complicated-crohns-disease-benefits-for-predicting-therapy-response" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168994.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">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> The Design and Implementation of an Enhanced 2D Mesh Switch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manel%20Langar">Manel Langar</a>, <a href="https://publications.waset.org/abstracts/search?q=Riad%20Bourguiba"> Riad Bourguiba</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaouhar%20Mouine"> Jaouhar Mouine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we propose the design and implementation of an enhanced wormhole virtual channel on chip router.

This work focuses on the use of three new green inhibitors for reducing calcium carbonate scale formation: gallic acid, quercetin and alginate, and on the comparison between them. These inhibitors have proven to be green antiscalants because they have no impact on the environment. Electrochemical methods (chronoamperometry and impedancemetry) were used to evaluate their performance. According to the study, these inhibitors are excellent green chemical inhibitors of scaling, and the best inhibitor is quercetin because it gave a good result with a lower concentration (2mg/L) compared to others inhibitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scaling" title="scaling">scaling</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20inhibitor" title=" green inhibitor"> green inhibitor</a>, <a href="https://publications.waset.org/abstracts/search?q=chronoamperometry" title=" chronoamperometry"> chronoamperometry</a>, <a href="https://publications.waset.org/abstracts/search?q=impedancemetry" title=" impedancemetry"> impedancemetry</a> </p> <a href="https://publications.waset.org/abstracts/167621/use-of-electrochemical-methods-for-the-inhibition-of-scaling-with-green-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167621.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">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Thermomechanical Damage Modeling of F114 Carbon Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20El%20Amri">A.

It is a useful tool to predict many phenomena present in the classical manufacturing forming processes such as fracture. But, the results of such numerical model depend strongly on the parameters of the constitutive behavior model. The influences of thermal and mechanical loads cause damage. The temperature and strain rate dependent materials’ properties and their modelling are discussed. A Johnson-Cook Model of damage has been selected for the numerical simulations. Virtual software called the ABAQUS 6.11 is used for finite element analysis. This model was introduced in order to give information concerning crack initiation during thermal and mechanical loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermo-mechanical%20fatigue" title="thermo-mechanical fatigue">thermo-mechanical fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a> </p> <a href="https://publications.waset.org/abstracts/46261/thermomechanical-damage-modeling-of-f114-carbon-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46261.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">393</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">23</span> Therapeutic Potential of Cannabis in Cancer: Advances in Clinical Research and Pharmacogenomic Aspects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boucha%C3%AFb%20Gazzaz">Bouchaïb Gazzaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20El%20Amri"> Hamid El Amri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hind%20Dehbi"> Hind Dehbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderraouf%20Hilali"> Abderraouf Hilali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Medical cannabis has been cultivated and used in many countries around the world. The story of the use of cannabis as a therapeutic agent is difficult to trace, in particular, because the laws regulating its production, distribution, possession, and consumption are relatively recent. Nowadays, in countries where it is authorized, medical cannabis is used in a very wide variety of illnesses and pathologies, particularly in cancer cures. Presently, cannabinoid receptor agonists (like nabilone and dronabinol) are used for reducing chemotherapy induced vomiting. This review aims to discuss a recent finding on the use of therapeutic cannabis in patients with cancer. First, this work addresses the progress made in the use of cannabinoids as therapeutic agent and their application in the treatment of different types of cancer.

Since different financial assets are traded based on these market sector returns, it’s important for financial market participants to understand the volatility transmission mechanism over time and across these series in order to make optimal portfolio allocation decisions. We examine weekly returns from January 1, 2003 to November 30, 2012 and find evidence of significant transmission of shocks and volatilities between oil prices and some of the examined financial markets. The findings support the idea of cross-market hedging and sharing of common information by investors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20prices" title="oil prices">oil prices</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20indices%20returns" title=" stock indices returns"> stock indices returns</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20volatility" title=" oil volatility"> oil volatility</a>, <a href="https://publications.waset.org/abstracts/search?q=contagion" title=" contagion"> contagion</a>, <a href="https://publications.waset.org/abstracts/search?q=DCC-multivariate%20%28FI%29%20GARCH" title=" DCC-multivariate (FI) GARCH"> DCC-multivariate (FI) GARCH</a> </p> <a href="https://publications.waset.org/abstracts/20756/on-the-impact-of-oil-price-fluctuations-on-stock-markets-a-multivariate-long-memory-garch-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20756.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">533</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> The Role of Personality Type as Predictor of Trust among Ridesharing Community: Study in Nebengers Community Jakarta</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Firdaus%20Amri">Firdaus Amri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ima%20Sri%20Rahmani"> Ima Sri Rahmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traffic jam becomes the main problem among the people in a metropolitan city, especially in Indonesia. Nebengers, as one of ridesharing community in Indonesia, offer solutions against this problem. Nebengers is a social media community that connect people who want to give the ride and who want to ask for the ride. But in reality, Nebengers still have quite problems, especially regarding the safety issue. Practically, in this issue, they (people in Nebengers) only depend on trust between the one who gives the ride and who asks for the ride. Trust is defined as an expectation that partners, including potential partners, have goodwill and benign intent in their dealing with one and another. This paper will examine the role of personality type as predictor of trust among Nebengers community. Hexaco Personality consists of six dimensions (honesty-humility, emotionality, agreeableness, conscientiousness, extraversion, and openness to experience) is used in this research. By using snowball sampling, we took 250 respondents from Nebengers community as participants for this research. They complete questionnaires which are provided in online form. The role of each personality type as a basic analysis to understand trust among Nebengers community will be discussed in this research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nebengers" title="Nebengers">Nebengers</a>, <a href="https://publications.waset.org/abstracts/search?q=personality%20type" title=" personality type"> personality type</a>, <a href="https://publications.waset.org/abstracts/search?q=ridesharing" title=" ridesharing"> ridesharing</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a> </p> <a href="https://publications.waset.org/abstracts/42657/the-role-of-personality-type-as-predictor-of-trust-among-ridesharing-community-study-in-nebengers-community-jakarta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42657.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">360</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Hard Water Softening by Chronoamperometry and Impedancemetry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Ghizellaoui">Samira Ghizellaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Manel%20Boumagoura"> Manel Boumagoura</a>, <a href="https://publications.waset.org/abstracts/search?q=Rayane%20Menzri"> Rayane Menzri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ground water Hamma rich in calcium and bicarbonate likely to deposit the tartar and subsequently lead to the obstruction of the pipes and the seizing of the stopping devices in addition to the financial losses resulting there from. It is therefore necessary to optimise an antiscaling treatment in order to avoid the risk of formation of tartar deposits in the various installations and to protect the equipment in contact with this water. MgCl2 is the chemical inhibitor which was tested. To optimise the effective concentration of this product, we used two electrochemical methods (chronoamperometry and impedancemetry) to identify the best method for optimizing antiscaling treatment. IR, RX, Raman spectroscopy and SEM indicate that the raw waters of Hamma give precipitates in the form of calcite (the most stable form), with the presence of a small amount of magnesian calcite and aragonite.

To reduce their complexity, an abstract view of the system can simplify its development. To overcome this problem, we propose a method to decompose systems into subsystems while reducing their coupling. These subsystems represent components. Consisting of an existing object-oriented systems, the main idea of our approach is based on modelling as graphs all entities of an oriented object source code. Such modelling is easy to handle, so we can apply restructuring algorithms based on graph metrics. The particularity of our approach consists in integrating in addition to standard metrics, such as coupling and cohesion, some graph metrics giving more precision during the components identication. To treat this problem, we relied on the ROMANTIC approach that proposed a component-based software architecture recovery from an object oriented system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20reengineering" title="software reengineering">software reengineering</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20component%0D%0Aand%20interfaces" title=" software component and interfaces"> software component and interfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=metrics" title=" metrics"> metrics</a>, <a href="https://publications.waset.org/abstracts/search?q=graphs" title=" graphs"> graphs</a> </p> <a href="https://publications.waset.org/abstracts/13322/software-component-identification-from-its-object-oriented-code-graph-metrics-based-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13322.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">501</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Study of Biodegradable Composite Materials Based on Polylactic Acid and Vegetal Reinforcements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manel%20Hannachi">Manel Hannachi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20Nechiche"> Mustapha Nechiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Azem"> Said Azem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on biodegradable materials made from Poly-lactic acid (PLA) and vegetal reinforcements. Three materials are developed from PLA, as a matrix, and : (i) olive kernels (OK); (ii) alfa (α) short fibers and (iii) OK+ α mixture, as reinforcements. After processing of PLA pellets and olive kernels in powder and alfa stems in short fibers, three mixtures, namely PLA-OK, PLA-α, and PLA-OK-α are prepared and homogenized in Turbula®. These mixtures are then compacted at 180°C under 10 MPa during 15 mn. Scanning Electron Microscopy (SEM) examinations show that PLA matrix adheres at surface of all reinforcements and the dispersion of these ones in matrix is good. X-ray diffraction (XRD) analyses highlight an increase of PLA inter-reticular distances, especially for the PLA-OK case. These results are explained by the dissociation of some molecules derived from reinforcements followed by diffusion of the released atoms in the structure of PLA. This is consistent with Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) analysis results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alfa%20short%20fibers" title="alfa short fibers">alfa short fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20composite" title=" biodegradable composite"> biodegradable composite</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20kernels" title=" olive kernels"> olive kernels</a>, <a href="https://publications.waset.org/abstracts/search?q=poly-lactic%20acid" title=" poly-lactic acid"> poly-lactic acid</a> </p> <a href="https://publications.waset.org/abstracts/85801/study-of-biodegradable-composite-materials-based-on-polylactic-acid-and-vegetal-reinforcements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85801.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">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Coordination Behavior, Theoretical Studies, and Biological Activity of Some Transition Metal Complexes with Oxime Ligands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noura%20Kichou">Noura Kichou</a>, <a href="https://publications.waset.org/abstracts/search?q=Manel%20Tafergguenit"> Manel Tafergguenit</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabila%20Ghechtouli"> Nabila Ghechtouli</a>, <a href="https://publications.waset.org/abstracts/search?q=Zakia%20Hank"> Zakia Hank</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this work is to synthesize, characterize and evaluate the biological activity of two Ligands : glyoxime and dimethylglyoxime, and their metal Ni(II) chelates.

Studied samples are found to be low in moisture and therefore safe from fermentation, low in HMF level and high in diastase activity. Additionally the diastase activity and the HMF content are widely recognized parameters indicating the freshness of honey. Phenolic compounds present in honey are classified into two groups - simple phenols and polyphenols. The simple phenols in honey are various phenol acids, but polyphenols are various flavonoids and flavonides. The aim of our work was to determine antioxidant properties of various Algerian honey samples–the total phenol content, total flavonoids content, as well as honey anti radical activity.The quality of honey samples differs on account of various factors such as season, packaging and processing conditions, floral source, geographical origin and storage period. It is important that precautions should be taken to ensure standardization and rationalization of beekeeping techniques, manufacturing procedures and storing processes to improve honey quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=honey" title="honey">honey</a>, <a href="https://publications.waset.org/abstracts/search?q=physico-chemical%20characterization" title=" physico-chemical characterization"> physico-chemical characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20coumpound" title=" phenolic coumpound"> phenolic coumpound</a>, <a href="https://publications.waset.org/abstracts/search?q=HMF" title=" HMF"> HMF</a>, <a href="https://publications.waset.org/abstracts/search?q=diastase%20activity" title=" diastase activity"> diastase activity</a> </p> <a href="https://publications.waset.org/abstracts/10564/physicochemical-heavy-metals-analysis-of-some-multi-floral-algerian-honeys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10564.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">423</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Molecular Electrostatic Potential in Z-3N(2-Ethoxyphenyl), 2-N'(2-Ethoxyphenyl) Imino Thiazolidin-4-one Molecule by Ab Initio and DFT Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manel%20Boulakoud">Manel Boulakoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkader%20Chouaih"> Abdelkader Chouaih</a>, <a href="https://publications.waset.org/abstracts/search?q=Fodil%20Hamzaoui"> Fodil Hamzaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work we are interested in the determination of the Molecular electrostatic potential (MEP) in Z-3N(2-Ethoxyphenyl), 2-N’(2-Ethoxyphenyl) imino thiazolidin-4-one molecule by ab initio and Density Functional Theory (DFT) in the ground state. The MEP is related to the electronic density and is a very useful descriptor in understanding sites for electrophilic attack and nucleophilic reactions as well as hydrogen bonding interactions. First, geometry optimization was carried out using Hartree–Fock (HF) and DFT methods with 6-311G(d,p) basis set. In order to get more information on the molecule, its stability has been analyzed by natural bond orbital (NBO) analysis. Mulliken population analyses have been calculated. Finally, the molecular electrostatic potential (MEP) and HOMO-LUMO energy levels have been performed. The calculated HOMO and LUMO energies show also the charge transfer within the molecule. The energy gap obtained is about 4 eV which explain the stability of the studied compound. The obtained molecular electrostatic potential from the two methods confirms the nature of the electron charge transfer at the molecular shell and locate the electropositive part and the electronegative part in molecular scale of the title compound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFT" title="DFT">DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=ab%20initio" title=" ab initio"> ab initio</a>, <a href="https://publications.waset.org/abstracts/search?q=HOMO-LUMO" title=" HOMO-LUMO"> HOMO-LUMO</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20compounds" title=" organic compounds"> organic compounds</a> </p> <a href="https://publications.waset.org/abstracts/43840/molecular-electrostatic-potential-in-z-3n2-ethoxyphenyl-2-n2-ethoxyphenyl-imino-thiazolidin-4-one-molecule-by-ab-initio-and-dft-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43840.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">535</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">12</span> The Differences on the Surface Roughness of Glass Ionomer Cement as the Results of Brushing with Whitening and Conventional Toothpaste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aulina%20R.%20Rahmi">Aulina R.

Restoration materials could undergo changes in their clinical properties such as changes in roughness of the restoration`s surface. An increase of surface roughness accelerates bacterial colonization and plaque maturation. In the oral cavity, GIC was exposed to various substances, such as toothpaste, an oral care product used during toothbrushing. One of the popular toothpaste is whitening toothpaste. Abrasive and chemical agents such as hydrogen peroxide in whitening toothpaste could increase the surface roughness of restorative materials. Objective: To determine the differences on the surface roughness of glass ionomer cement that was brushed with whitening and conventional toothpaste. Method: This study was done using experimental laboratory method with pre and post test design. There were 36 samples which were divided into 2 groups. The first group was brushed with whitening toothpaste and the second group was brushed with conventional toothpaste, each for 2 minutes. Surface roughness value of the specimens was measured by using Roughness Tester test. Result: The data was analyzed by using independent t-test and the result of this study showed there was a significant difference between the surface of glass ionomer cement which was brushed with whitening and conventional toothpaste (p=0,000). Conclusion: Glass ionomer cement that was brushed with whitening toothpaste produced more roughness than conventional toothpaste. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glass%20ionomer%20cement" title="glass ionomer cement">glass ionomer cement</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=toothpaste" title=" toothpaste"> toothpaste</a>, <a href="https://publications.waset.org/abstracts/search?q=roughness%20tester" title=" roughness tester "> roughness tester </a> </p> <a href="https://publications.waset.org/abstracts/73785/the-differences-on-the-surface-roughness-of-glass-ionomer-cement-as-the-results-of-brushing-with-whitening-and-conventional-toothpaste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73785.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">288</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">11</span> A Real Time Development Study for Automated Centralized Remote Monitoring System at Royal Belum Forest</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amri%20Yusoff">Amri Yusoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrizuan%20Shafiril"> Shahrizuan Shafiril</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashardi%20Abas"> Ashardi Abas</a>, <a href="https://publications.waset.org/abstracts/search?q=Norma%20Che%20Yusoff"> Norma Che Yusoff</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, illegal logging has been causing much effect to our forest. Some of it causes a flash flood, avalanche, global warming, and etc. This comprehensibly makes us wonder why, what, and who has made it happened. Often, it already has been too late after we have known the cause of it. Even the Malaysian Royal Belum forest has not been spared from land clearing or illegal activity by the natives although this area has been gazetted as a protected area preserved for future generations. Furthermore, because of its sizeable and wide area, these illegal activities are difficult to monitor and to maintain. A critical action must be called upon to prevent all of these unhealthy activities from recurrence. Therefore, a remote monitoring device must be developed in order to capture critical real-time data such as temperature, humidity, gaseous, fire, and rain detection which indicates the current and preserved natural state and habitat in the forest. Besides, this device location can be detected via GPS by showing the latitudes and longitudes of its current location and then to be transmitted by SMS via GSM system.

The main water supply that supplies the city of Constantine with drinking water is underground water called Hamma water. This water has a very high hardness of around 590 mg/L CaCO₃. This leads to the formation of scale, consisting mainly of calcium carbonate, which can be responsible for the clogging of valves and the deterioration of equipment (water heaters, washing machines and encrustations in the pipes). Plant extracts used as scale inhibitors have attracted the attention of several researchers. In recent years, green inhibitors have attracted great interest because they are biodegradable, non-toxic and do not affect the environment. The aim of our work is to evaluate the effectiveness of a chemical antiscale treatment in the presence of three green inhibitors: gallicacid; quercetin; alginate, and three mixtures: (gallic acid-quercetin); (quercetin-alginate); (gallic acid-alginate). The results show that the inhibitory effect is manifested from an addition of 1mg/L of gallic acid, 10 mg/L of quercetin, 0.2 mg/L of alginate, 0.4mg/L of (gallic acid-quercetin), 2mg/L of (quercetin-alginate) and 0.4 mg/L of (gallic acid-alginate). On the other hand, 100 mg/L (Drinking water standard) of Ca2+is reached for partial softening at 4 mg/L of gallic acid, 40 mg/L of quercetin, 0.6mg/L of alginate, 4mg/L of (gallic acid-quercetin), 10mg/L of (quercetin-alginate) and 1.6 mg/L of (gallic acid-alginate). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water" title="water">water</a>, <a href="https://publications.waset.org/abstracts/search?q=scaling" title=" scaling"> scaling</a>, <a href="https://publications.waset.org/abstracts/search?q=calcium%20carbonate" title=" calcium carbonate"> calcium carbonate</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20inhibitor" title=" green inhibitor"> green inhibitor</a> </p> <a href="https://publications.waset.org/abstracts/167612/application-of-chemical-tests-for-the-inhibition-of-scaling-from-hamma-hard-waters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167612.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">68</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">9</span> Effect of Cistanche tinctoria Methanolic Extract on the Maternal-Fetal Outcome and Oxidative Stress Biomarkers of Streptozotocin-Induced Diabetic Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Bouzitouna">Amina Bouzitouna</a>, <a href="https://publications.waset.org/abstracts/search?q=Kheireddine%20Ouali"> Kheireddine Ouali</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Amri"> Sandra Amri</a>, <a href="https://publications.waset.org/abstracts/search?q=Houria%20Rahmoun"> Houria Rahmoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Mourad%20Bensouilah"> Mourad Bensouilah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim of this study: To evaluate the effect of Cisthanche tinctoria treatment on maternal-fetal outcome and antioxidant systems of streptozotocin-induced diabetic rats. Materials and methods: Virgin female Wistar rats were injected with 50 mg/kg streptozotocin before mating. Oral administration of an methanolic extract of Cistanche tinctoria was given to non-diabetic and diabetic pregnant rats at doses of 200 mg/kg from 0 to 19th day of pregnancy. At day 20 of pregnancy the rats were killed and a maternal blood sample was collected for the determination Vitamin C (Vit C) and malonaldehyde (MDA). The gravid uterus was weighed with its contents and fetuses were analyzed. Results and conclusion: The data showed that the diabetic dams presented an increased glycemic level, resorption, placental weight, placental index, and fetal anomalies, and reduced VIT C and MDA determinations, live fetuses, maternal weight gain, gravid uterine weight, and fetal weight. It was also verified that Cisthanche tictoria treatment had no hypoglycemic effect, did not improve maternal outcomes in diabetic rats, but it contributed to maintain GSH concentration similarly to non-diabetic groups, suggesting relation with the decreased incidence of visceral anomalies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cistanche%20tinctoria" title="cistanche tinctoria">cistanche tinctoria</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes" title=" diabetes"> diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20outcome" title=" reproductive outcome"> reproductive outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=anomaly" title=" anomaly"> anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=orobanchac%C3%A9es" title=" orobanchacées"> orobanchacées</a> </p> <a href="https://publications.waset.org/abstracts/13058/effect-of-cistanche-tinctoria-methanolic-extract-on-the-maternal-fetal-outcome-and-oxidative-stress-biomarkers-of-streptozotocin-induced-diabetic-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13058.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">457</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">8</span> Malachite Green and Red Congo Dyes Adsorption onto Chemical Treated Sewage Sludge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zamouche%20Meriem">Zamouche Meriem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehcene%20Ismahan"> Mehcene Ismahan</a>, <a href="https://publications.waset.org/abstracts/search?q=Temmine%20Manel"> Temmine Manel</a>, <a href="https://publications.waset.org/abstracts/search?q=Bencheikh%20Lehocine%20Mosaab"> Bencheikh Lehocine Mosaab</a>, <a href="https://publications.waset.org/abstracts/search?q=Meniai%20Abdeslam%20Hassen"> Meniai Abdeslam Hassen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the adsorption of Malachite Green (MG) by chemical treated sewage sludge has been studied. The sewage sludge, collected from drying beds of the municipal wastewater treatment station of IBN ZIED, Constantine, Algeria, was treated by different acids such us HNO₃, H₂SO₄, H₃PO₄ for modifying its aptitude to removal the MG from aqueous solutions. The results obtained shows that the sewage sludge activated by sulfuric acid give the highest elimination amounts of MG (9.52 mg/L) compared by the other acids used. The effects of operation parameters have been investigated, the results obtained show that the adsorption capacity per unit of adsorbent mass decreases from 18.69 to 1.20 mg/g when the mass of the adsorbent increases from 0.25 to 4 g respectively, the optimum mass for which a maximum of elimination of the dye is equal to 0.5g. The increasing in the temperature of the solution results in a slight decrease in the adsorption capacity of the chemically treated sludge. The highest amount of dye adsorbed by CSSS (9.56 mg/g) was observed for the optimum temperature of 25°C. The chemical activated sewage sludge proved its effectiveness for the removal of the Red Congo (RC), but by comparison the adsorption of the two dyes studies, we noted that the sludge has more affinity to adsorb the (MG). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20activation" title=" chemical activation"> chemical activation</a>, <a href="https://publications.waset.org/abstracts/search?q=malachite%20green" title=" malachite green"> malachite green</a>, <a href="https://publications.waset.org/abstracts/search?q=sewage%20sludge" title=" sewage sludge"> sewage sludge</a> </p> <a href="https://publications.waset.org/abstracts/94506/malachite-green-and-red-congo-dyes-adsorption-onto-chemical-treated-sewage-sludge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94506.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">7</span> Elaboration and Characterization of Silver Nanoparticles for Therapeutic and Environmental Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manel%20Bouloudenine">Manel Bouloudenine</a>, <a href="https://publications.waset.org/abstracts/search?q=Karima%20Djeddou"> Karima Djeddou</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadjer%20Ben%20Manser"> Hadjer Ben Manser</a>, <a href="https://publications.waset.org/abstracts/search?q=Hana%20Soualah%20Alila"> Hana Soualah Alila</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohmed%20Bououdina"> Mohmed Bououdina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This survey research involves the elaboration and characterization of silver nanoparticles for therapeutic and environmental applications. The silver nanoparticles "Ag NPs" were synthesized by reducing AgNO3 with microwaves. The characterization of nanoparticles was done by using Transmission Electron Microscopy " TEM ", Energy Dispersive Spectroscopy "EDS", Selected Area Electron Diffraction "SEAD", UV-Visible Spectroscopy and Dynamic Light Scattering "DLS". Transmission Electron Microscopy and Electron Diffraction have confirmed the nanoscale, the shape, and the crystalline quality of as synthesized silver nanoparticles. Elementary analysis has proved the purity of Ag NPs and the presence of the Surface Plasmon Resonance phenomenon "SPR". A strong absorption shift was observed in the visible range of the UV-visible spectrum of as synthesized Ag NPs, which indicates the presence of metallic silver. When the strong absorption in the ultraviolet range of the spectrum has revealed the presence of ionic Ag NPs ionic Ag aggregates species. The autocorrelation function measured by the Dynamic Light Scattering has shown a strong monodispersed character of Ag NPs, which is indicated by the presence of a single size population, with a minima and a maxima laying between 40 and 111 nm. Related to other research, our results confirm the performance properties of as synthesized Ag NPs, which allows them to be performing in many technological applications, including therapeutic and environmental ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silvers%20nanoparticles" title="silvers nanoparticles">silvers nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=microwaves" title=" microwaves"> microwaves</a>, <a href="https://publications.waset.org/abstracts/search?q=EDS" title=" EDS"> EDS</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM" title=" TEM"> TEM</a> </p> <a href="https://publications.waset.org/abstracts/146054/elaboration-and-characterization-of-silver-nanoparticles-for-therapeutic-and-environmental-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146054.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">147</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">6</span> Potential Effects of Climate Change on Streamflow, Based on the Occurrence of Severe Floods in Kelantan, East Coasts of Peninsular Malaysia River Basin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhd.%20Barzani%20Gasim">Muhd.

The disaster has caused some troubles such loss of property, loss of life and discomfort of people involved. This problem occurs as a result of climate change leading to increased stream flow rate as a result of disruption to regional hydrological cycles. The aim of the study is to determine hydrologic processes in the east coasts of Peninsular Malaysia, especially in Kelantan Basin. Parameterized to account for the spatial and temporal variability of basin characteristics and their responses to climate variability. For hydrological modeling of the basin, the Soil and Water Assessment Tool (SWAT) model such as relief, soil type, and its use, and historical daily time series of climate and river flow rates are studied. The interpretation of Landsat map/land uses will be applied in this study. The combined of SWAT and climate models, the system will be predicted an increase in future scenario climate precipitation, increase in surface runoff, increase in recharge and increase in the total water yield. As a result, this model has successfully developed the basin analysis by demonstrating analyzing hydrographs visually, good estimates of minimum and maximum flows and severe floods observed during calibration and validation periods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=east%20coasts%20of%20Peninsular%20Malaysia" title="east coasts of Peninsular Malaysia">east coasts of Peninsular Malaysia</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelantan%20river%20basin" title=" Kelantan river basin"> Kelantan river basin</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20and%20maximum%20flows" title=" minimum and maximum flows"> minimum and maximum flows</a>, <a href="https://publications.waset.org/abstracts/search?q=severe%20floods" title=" severe floods"> severe floods</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT%20model" title=" SWAT model"> SWAT model</a> </p> <a href="https://publications.waset.org/abstracts/86824/potential-effects-of-climate-change-on-streamflow-based-on-the-occurrence-of-severe-floods-in-kelantan-east-coasts-of-peninsular-malaysia-river-basin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86824.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">262</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">5</span> Piracy in Southeast Asian Waters: Problems, Legal Measures and Way Forward</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Almaududy%20Amri">Ahmad Almaududy Amri </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Southeast Asia is considered as an area which is important in terms of piratical studies. There are several reasons to this argument: firstly, it has the second highest figure of piracy attacks in the world from 2008 to 2012. Only the African Region transcends the number of piracies that were committed in Southeast Asia. Secondly, the geographical location of the region is very important to world trade. There are several sea lanes and straits which are normally used for international navigation mainly for trade purposes. In fact, there are six out of 25 busiest ports all over the world located in Southeast Asia. In ancient times, the main drivers of piracy were raiding for plunder and capture of slaves; however, in modern times, developments in politics, economics and even military technology have drastically altered the universal crime of piracy. There are a variety of motives behind modern day piracy including economic gains from receiving ransoms from government or ship companies, political and even terrorist reasons. However, it cannot be denied that piratical attacks persist and continue. States have taken measures both at the international and regional level in order to eradicate piratical attacks. The United Nations Convention on the Law of the Sea and the Convention on the Suppression of Unlawful Act against the Safety of Navigation served as the two main international legal frameworks in combating piracy. At the regional level, Regional Cooperation Agreement against Piracy and Armed Robbery and ASEAN measures are regard as prominent in addressing the piracy problem. This paper will elaborate the problems of piracy in Southeast Asia and examine the adequacy of legal frameworks at both the international and regional levels in order address the current legal measures in combating piracy. Furthermore, it will discuss current challenges in the implementation of anti-piracy measures at the international and regional levels as well as the way forward in addressing the issue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=piracy" title="piracy">piracy</a>, <a href="https://publications.waset.org/abstracts/search?q=Southeast%20Asia" title=" Southeast Asia"> Southeast Asia</a>, <a href="https://publications.waset.org/abstracts/search?q=maritime%20security" title=" maritime security"> maritime security</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20frameworks" title=" legal frameworks"> legal frameworks</a> </p> <a href="https://publications.waset.org/abstracts/8418/piracy-in-southeast-asian-waters-problems-legal-measures-and-way-forward" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8418.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">503</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">4</span> Charge Trapping on a Single-wall Carbon Nanotube Thin-film Transistor with Several Electrode Metals for Memory Function Mimicking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ameni%20Mahmoudi">Ameni Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Manel%20Troudi"> Manel Troudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Bondavalli"> Paolo Bondavalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Sghaier"> Nabil Sghaier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the charge storage on thin-film SWCNT transistors was investigated, and C-V hysteresis tests showed that interface charge trapping effects predominate the memory window. Two electrode materials were utilized to demonstrate that selecting the appropriate metal electrode clearly improves the conductivity and, consequently, the SWCNT thin-film’s memory effect. Because their work function is similar to that of thin-film carbon nanotubes, Ti contacts produce higher charge confinement and show greater charge storage than Pd contacts. For Pd-contact CNTFETs and CNTFETs with Ti electrodes, a sizable clockwise hysteresis window was seen in the dual sweep circle with a threshold voltage shift of V11.52V and V9.7V, respectively. The SWCNT thin-film based transistor is expected to have significant trapping and detrapping charges because of the large C-V hysteresis. We have found that the predicted stored charge density for CNTFETs with Ti contacts is approximately 4.01×10-2C.m-2, which is nearly twice as high as the charge density of the device with Pd contacts. We have shown that the amount of trapped charges can be changed by sweeping the range or Vgs rate. We also looked into the variation in the flat band voltage (V FB) vs. time in order to determine the carrier retention period in CNTFETs with Ti and Pd electrodes. The outcome shows that memorizing trapped charges is about 300 seconds, which is a crucial finding for memory function mimicking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charge%20storage" title="charge storage">charge storage</a>, <a href="https://publications.waset.org/abstracts/search?q=thin-film%20SWCNT%20based%20transistors" title=" thin-film SWCNT based transistors"> thin-film SWCNT based transistors</a>, <a href="https://publications.waset.org/abstracts/search?q=C-V%20hysteresis" title=" C-V hysteresis"> C-V hysteresis</a>, <a href="https://publications.waset.org/abstracts/search?q=memory%20effect" title=" memory effect"> memory effect</a>, <a href="https://publications.waset.org/abstracts/search?q=trapping%20and%20detrapping%20charges" title=" trapping and detrapping charges"> trapping and detrapping charges</a>, <a href="https://publications.waset.org/abstracts/search?q=stored%20charge%20density" title=" stored charge density"> stored charge density</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20carrier%20retention%20time" title=" the carrier retention time"> the carrier retention time</a> </p> <a href="https://publications.waset.org/abstracts/159141/charge-trapping-on-a-single-wall-carbon-nanotube-thin-film-transistor-with-several-electrode-metals-for-memory-function-mimicking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159141.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">81</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">3</span> The Roles of Art Extra Activities in Promoting the Psychological Sides in the Higher Education Institutions and Its Challenges: Oman as a Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hamood%20Al-Amri">Mohammed Hamood Al-Amri</a>, <a href="https://publications.waset.org/abstracts/search?q=Fakhriya%20Khalfan%20Al%20Yahyai"> Fakhriya Khalfan Al Yahyai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current case study aimed to investigate the roles of art extra activities in promoting the psychological sides in the Higher Education Institutions in the Sultanate of Oman and its challenges.

This study ended up with some recommendations and suggestions to activate the roles of art extra activities in promoting the psychological sides in the Higher Education Institutions with references to some solutions for the challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=art%20activities" title="art activities">art activities</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20sides" title=" psychological sides"> psychological sides</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education%20institutions" title=" higher education institutions"> higher education institutions</a>, <a href="https://publications.waset.org/abstracts/search?q=challenges%20and%20oman" title=" challenges and oman"> challenges and oman</a> </p> <a href="https://publications.waset.org/abstracts/159909/the-roles-of-art-extra-activities-in-promoting-the-psychological-sides-in-the-higher-education-institutions-and-its-challenges-oman-as-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159909.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">92</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">2</span> Distribution, Seasonal Phenology and Infestation Dispersal of the Chickpea Leafminer Liriomyza cicerina (Diptera: Agromizidae) on Two Winter and Spring Chickpea Varieties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abir%20Soltani">Abir Soltani</a>, <a href="https://publications.waset.org/abstracts/search?q=Moez%20Amri"> Moez Amri</a>, <a href="https://publications.waset.org/abstracts/search?q=Jouda%20Mediouni%20Ben%20Jem%C3%A2a"> Jouda Mediouni Ben Jemâa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In North Africa, the chickpea leafminer Liriomyza cicerina (Rondani) (Diptera: Agromizidae) is one of the major damaging pests affecting both spring and winter-planted chickpea. Damage is caused by the larvae which feed in the leaf mesophyll tissue, resulting in desiccation and premature leaf fall that can cause severe yield losses. In the present work, the distribution and the seasonal phenology of L. cicerina were studied on two chickpea varieties; a winter variety Beja 1 which is the most cultivated variety in Tunisia and a spring-sown variety Amdoun 1. The experiment was conducted during the cropping season 2015-2016. In the experimental research station Oued Beja, in the Beja region (36°44’N; 9°13’E). To determine the distribution and seasonal phenology of L. cicerina in both studied varieties Beja 1 and Amdoun 1, respectively 100 leave samples (50 from the top and 50 from the base) were collected from 10 chickpea plants randomly chosen from each field. The sampling was done during three development stages (i) 20-25 days before flowering (BFL), (ii) at flowering (FL) and (ii) at pod setting stage (PS). For each plant, leaves were checked from the base till the upper ones for the insect infestation progress into the plant in correlation with chickpea growth Stages. Fly adult populations were monitored using 8 yellow sticky traps together with weekly leaves sampling in each field. The traps were placed 70 cm above ground. Trap catches were collected once a week over the cropping season period. Results showed that L. cicerina distribution varied among both studied chickpea varieties and crop development stage all with seasonal phenology. For the winter chickpea variety Beja 1, infestation levels of 2%, 10.3% and 20.3% were recorded on the bases plant part for BFL, FL and PS stages respectively against 0%, 8.1% and 45.8% recorded for the upper plant part leaves for the same stages respectively. For the spring-sown variety Amdoun 1 the infestation level reached 71.5% during flowering stage. Population dynamic study revealed that for Beja 1 variety, L. cicerina accomplished three annual generations over the cropping season period with the third one being the most important with a capture level of 85 adult/trap by mid-May against a capture level of 139 adult/trap at the end May recorded for cv. Amdoun 1. Also, results showed that L. cicerina field infestation dispersal depends on the field part and on the crop growth stage. The border areas plants were more infested than the plants placed inside the plots. For cv. Beja 1, border areas infestations were 11%, 28% and 91.2% for BFL, FL and PS stages respectively, against 2%, 10.73% and 69.2% recorded on the on the inside plot plants during the for the same growth stages respectively. For the cv. Amdoun1 infestation level of 90% was observed on the border plants at FL and PS stages against an infestation level less than 65% recorded inside the plot. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leaf%20miner" title="leaf miner">leaf miner</a>, <a href="https://publications.waset.org/abstracts/search?q=liriomyza%20cicerina" title=" liriomyza cicerina"> liriomyza cicerina</a>, <a href="https://publications.waset.org/abstracts/search?q=chickpea" title=" chickpea"> chickpea</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution" title=" distribution"> distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=seasonal%20phenology" title=" seasonal phenology"> seasonal phenology</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/58151/distribution-seasonal-phenology-and-infestation-dispersal-of-the-chickpea-leafminer-liriomyza-cicerina-diptera-agromizidae-on-two-winter-and-spring-chickpea-varieties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58151.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">282</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">1</span> Analysis and Comparison of Asymmetric H-Bridge Multilevel Inverter Topologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manel%20Hammami">Manel Hammami</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriele%20Grandi"> Gabriele Grandi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, multilevel inverters have become more attractive for single-phase photovoltaic (PV) systems, due to their known advantages over conventional H-bridge pulse width-modulated (PWM) inverters. They offer improved output waveforms, smaller filter size, lower total harmonic distortion (THD), higher output voltages and others. The most common multilevel converter topologies, presented in literature, are the neutral-point-clamped (NPC), flying capacitor (FC) and Cascaded H-Bridge (CHB) converters. In both NPC and FC configurations, the number of components drastically increases with the number of levels what leads to complexity of the control strategy, high volume, and cost. Whereas, increasing the number of levels in case of the cascaded H-bridge configuration is a flexible solution. However, it needs isolated power sources for each stage, and it can be applied to PV systems only in case of PV sub-fields. In order to improve the ratio between the number of output voltage levels and the number of components, several hybrids and asymmetric topologies of multilevel inverters have been proposed in the literature such as the FC asymmetric H-bridge (FCAH) and the NPC asymmetric H-bridge (NPCAH) topologies. Another asymmetric multilevel inverter configuration that could have interesting applications is the cascaded asymmetric H-bridge (CAH), which is based on a modular half-bridge (two switches and one capacitor, also called level doubling network, LDN) cascaded to a full H-bridge in order to double the output voltage level. This solution has the same number of switches as the above mentioned AH configurations (i.e., six), and just one capacitor (as the FCAH). CAH is becoming popular, due to its simple, modular and reliable structure, and it can be considered as a retrofit which can be added in series to an existing H-Bridge configuration in order to double the output voltage levels. In this paper, an original and effective method for the analysis of the DC-link voltage ripple is given for single-phase asymmetric H-bridge multilevel inverters based on level doubling network (LDN). Different possible configurations of the asymmetric H-Bridge multilevel inverters have been considered and the analysis of input voltage and current are analytically determined and numerically verified by Matlab/Simulink for the case of cascaded asymmetric H-bridge multilevel inverters. A comparison between FCAH and the CAH configurations is done on the basis of the analysis of the DC and voltage ripple for the DC source (i.e., the PV system). The peak-to-peak DC and voltage ripple amplitudes are analytically calculated over the fundamental period as a function of the modulation index. On the basis of the maximum peak-to-peak values of low frequency and switching ripple voltage components, the DC capacitors can be designed. Reference is made to unity output power factor, as in case of most of the grid-connected PV generation systems. Simulation results will be presented in the full paper in order to prove the effectiveness of the proposed developments in all the operating conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20inverters" title="asymmetric inverters">asymmetric inverters</a>, <a href="https://publications.waset.org/abstracts/search?q=dc-link%20voltage" title=" dc-link voltage"> dc-link voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20doubling%20network" title=" level doubling network"> level doubling network</a>, <a href="https://publications.waset.org/abstracts/search?q=single-phase%20multilevel%20inverter" title=" single-phase multilevel inverter"> single-phase multilevel inverter</a> </p> <a href="https://publications.waset.org/abstracts/89726/analysis-and-comparison-of-asymmetric-h-bridge-multilevel-inverter-topologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89726.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">207</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
