class="card-text"><strong>Abstract:</strong></p> In the present work, we explored the potential of tribological behavior of tricalcium phosphate-Fluorapatite (β Tcp-Fap) bioceramic which has attracted considerable attention for orthopedics and dental applications. The approximate representatives Fap-βTcp were respectively [{13.26 wt%, 86.74 wt%} {19.9 wt%, 80.1 wt%},{ 26.52 wt%, 73.48 wt%}, {33.16 wt%, 66.84 wt%} and {40 wt%, 60 wt%}. The effects of Fluorapatite additives on friction and wear behavior were studied and discussed. The wear test was conducted using pion-disk tribometer at room temperature under dry condition using a constant sliding speed of 0,063 m/s, and three loads 3, 5 and 8 N. The wear rate and friction coefficient of β Tcp with different additive amounts were compared. An Alumina ball specimens were used as the pin and flat surface β Tcp-Fap specimens as the antagonist counterface. The results show a huge difference between the wear rate of β TCP samples and the other β TCP-Fap composites for all normal forces applied. This result shows the beneficial effect of fluorapatite on the tribological behavior of the β TCP. Moreover, we note that β Tcp-26% Fap specimens exhibit, under dry condition, the lower friction coefficient and the smaller wear rate than other biocomposites. Thereby, the friction and wear behavior is influenced by the addition of fluorapatite, the applied normal force, and the sliding velocity. To extend the understanding of the wear process, the surface topography of β Tcp-26% Fap specimens and the wear track obtained during the wear tests were studied using a surface profilometer, optical microscopy, and scanning electron microscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alumina" title="alumina">alumina</a>, <a href="https://publications.waset.org/abstracts/search?q=bioceramic" title=" bioceramic"> bioceramic</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20and%20wear%20test" title=" friction and wear test"> friction and wear test</a>, <a href="https://publications.waset.org/abstracts/search?q=tricalcium%20phosphate" title=" tricalcium phosphate"> tricalcium phosphate</a> </p> <a href="https://publications.waset.org/abstracts/55316/comparative-study-of-wear-and-friction-behavior-of-tricalcium-phosphate-fluorapatite-bioceramic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55316.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">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Electric Models for Crosstalk Predection: Analysis and Performance Evaluation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kachout%20Mnaouer">Kachout Mnaouer</a>, <a href="https://publications.waset.org/abstracts/search?q=Bel%20Hadj%20Tahar%20Jamel"> Bel Hadj Tahar Jamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Choubani%20Fethi"> Choubani Fethi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, three electric equivalent models to evaluate crosstalk between three-conductor transmission lines are proposed. First, electric equivalent models for three-conductor transmission lines are presented. Secondly, rigorous equations to calculate the per-unit length inductive and capacitive parameters are developed. These models allow us to calculate crosstalk between conductors. Finally, to validate the presented models, we compare the theoretical results with simulation data.

We focus, in this paper, on the semiautomatic annotation of the web pages. We propose an approach and a framework for semantic annotation of web pages entitled “Querying Web”. Our solution is an enhancement of the first result of annotation done by the “Semantic Radar” Plug-in on the web resources, by annotations using an enriched domain ontology. The concepts of the result of Semantic Radar may be connected to several terms of the ontology, but connections may be uncertain. We represent annotations as possibility distributions. We use the hierarchy defined in the ontology to compute degrees of possibilities. We want to achieve an automation of the fuzzy semantic annotation of web resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20semantic%20annotation" title="fuzzy semantic annotation">fuzzy semantic annotation</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20web" title=" semantic web"> semantic web</a>, <a href="https://publications.waset.org/abstracts/search?q=domain%20ontologies" title=" domain ontologies"> domain ontologies</a>, <a href="https://publications.waset.org/abstracts/search?q=querying%20web" title=" querying web"> querying web</a> </p> <a href="https://publications.waset.org/abstracts/1854/fuzzy-semantic-annotation-of-web-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1854.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">374</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Influence of Error Correction Codes on the Quality of Optical Broadband Connections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mouna%20Hemdi">Mouna Hemdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamel%20bel%20Hadj%20Tahar"> Jamel bel Hadj Tahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing development of multimedia applications requiring the simultaneous transport of several different services contributes to the evolution of the need for very high-speed network.

Our hypothesis is that if equity is reported at its fair value, this valuation is closely linked to market capitalization, so the weight of earnings weakens or even disappears in the Ohlson Model. Drawing on Canada's adoption of the International Financial Reporting Standards (IFRS), our results support our hypothesis that equity appears to include most of the relevant information for investors, while earnings have become less important. However, the predictive power of earnings does not disappear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fair%20value%20accounting" title="fair value accounting">fair value accounting</a>, <a href="https://publications.waset.org/abstracts/search?q=Ohlson%20model" title=" Ohlson model"> Ohlson model</a>, <a href="https://publications.waset.org/abstracts/search?q=IFRS%20adoption" title=" IFRS adoption"> IFRS adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=value-relevance%20of%20equity%20and%20earnings" title=" value-relevance of equity and earnings"> value-relevance of equity and earnings</a> </p> <a href="https://publications.waset.org/abstracts/106775/fair-value-accounting-and-evolution-of-the-ohlson-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106775.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">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Correlation Matrix for Automatic Identification of Meal-Taking Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghazi%20Bouaziz">Ghazi Bouaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrahim%20Derouiche"> Abderrahim Derouiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Damien%20Brulin"> Damien Brulin</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9l%C3%A8ne%20Pigot"> Hélène Pigot</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Campo"> Eric Campo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Automatic ADL classification is a crucial part of ambient assisted living technologies.

Therefore, we used a correlation matrix to extract custom rules that enable to detect ADLs, including eating activity. Data collected from 3 different individuals between 35 and 105 days allows the extraction of personalized eating patterns.

Jamel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electronic government initiatives and public participation to them are among the indicators of today's development criteria of the countries. After consequent two wars, Iraq's current position in, for example, UN's e-government ranking is quite concerning and did not improve in recent years, either. In the preparation of this work, we are motivated with the fact that handling geographic data of the public facilities and resources are needed in most of the e-government projects. Geographical information systems (GIS) provide most common tools not only to manage spatial data but also to integrate such type of data with nonspatial attributes of the features.

The main findings are threefold: i) the effect of a change in Sukuk issuances on the consumers’ utility level will be different from one generation to another, ii) an increase in taxes due to the increase in Sukuk and rents is covered by transfers made by the members of generation 1 in the form of inheritance, and iii) the existence of a positive relationship between the asset prices representative of Sukuk and the real activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sukuk" title="Sukuk">Sukuk</a>, <a href="https://publications.waset.org/abstracts/search?q=households" title=" households"> households</a>, <a href="https://publications.waset.org/abstracts/search?q=investors" title=" investors"> investors</a>, <a href="https://publications.waset.org/abstracts/search?q=overlapping%20generations%20model" title=" overlapping generations model"> overlapping generations model</a>, <a href="https://publications.waset.org/abstracts/search?q=wealth" title=" wealth"> wealth</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a> </p> <a href="https://publications.waset.org/abstracts/159984/essay-on-theoretical-modeling-of-the-wealth-effect-of-sukuk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159984.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">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Optimization of Dual Band Antenna on Silicon Substrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syrine%20lahmadi">Syrine lahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamel%20Bel%20Hadj%20Tahar"> Jamel Bel Hadj Tahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a rectangular antenna with slots integrated on silicon substrate operating in 60GHz, is studied and optimized.

The tensile strength of the composites increased modestly with higher fly ash loading, while there was a significant increase in the elastic modulus for the same composites. On the other hand, a decrease in elongation at UTS was observed upon increasing fly ash content due to increased rigidity of the composites. Similarly, the flexural modulus increased as the fly ash loading increased, where the composites containing 25 phr fly ash showed the highest flexural strength. Thermal properties of PVC-fly ash composites were determined by Thermo Gravimetric Analysis (TGA). The micro structural properties were studied by Scanning Electron Microscopy (SEM). SEM results confirm that fly ash particles were mechanically interlocked in PVC matrix with good inter facial interaction with the matrix. Particle agglomeration and debonding was observed in samples containing higher amounts of fly ash. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PVC%20foam" title="PVC foam">PVC foam</a>, <a href="https://publications.waset.org/abstracts/search?q=polyvinyl%20chloride" title=" polyvinyl chloride"> polyvinyl chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=rigid%20PVC" title=" rigid PVC"> rigid PVC</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash%20composites" title=" fly ash composites"> fly ash composites</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20composites" title=" polymer composites"> polymer composites</a> </p> <a href="https://publications.waset.org/abstracts/18474/enhanced-thermal-properties-of-rigid-pvc-foams-using-fly-ash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18474.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">390</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Is the Okun's Law Valid in Tunisia?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=El%20Andari%20Chifaa">El Andari Chifaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouaziz%20Rached"> Bouaziz Rached</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The central focus of this paper was to check whether the Okun’s law in Tunisia is valid or not. For this purpose, we have used quarterly time series data during the period 1990Q1-2014Q1. Firstly, we applied the error correction model instead of the difference version of Okun's Law, the Engle-Granger and Johansen test are employed to find out long run association between unemployment, production, and how error correction mechanism (ECM) is used for short run dynamic. Secondly, we used the gap version of Okun’s law where the estimation is done from three band pass filters which are mathematical tools used in macro-economic and especially in business cycles theory. The finding of the study indicates that the inverse relationship between unemployment and output is verified in the short and long term, and the Okun's law holds for the Tunisian economy, but with an Okun’s coefficient lower than required. Therefore, our empirical results have important implications for structural and cyclical policymakers in Tunisia to promote economic growth in a context of lower unemployment growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Okun%E2%80%99s%20law" title="Okun’s law">Okun’s law</a>, <a href="https://publications.waset.org/abstracts/search?q=validity" title=" validity"> validity</a>, <a href="https://publications.waset.org/abstracts/search?q=unit%20root" title=" unit root"> unit root</a>, <a href="https://publications.waset.org/abstracts/search?q=cointegration" title=" cointegration"> cointegration</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20correction%20model" title=" error correction model"> error correction model</a>, <a href="https://publications.waset.org/abstracts/search?q=bandpass%20filters" title=" bandpass filters"> bandpass filters</a> </p> <a href="https://publications.waset.org/abstracts/42765/is-the-okuns-law-valid-in-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42765.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">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Influence of Thermal Radiation on MHD Micropolar Fluid Flow, Heat and Mass Transfer over Vertical Flat Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alouaoui%20%20Redha">Alouaoui Redha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferhat%20Samira"> Ferhat Samira</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouaziz%20Mohamed%20Najib"> Bouaziz Mohamed Najib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we examine the thermal radiation effect on heat and mass transfer in steady laminar boundary layer flow of an incompressible viscous micropolar fluid over a vertical plate, with the presence of a magnetic field.

PVC foam-glass fiber composites (PVC-GF) were characterized for their dimensional stability, structural, thermal, and mechanical properties. Experimental results show that the dimensional stability, heat resistance, and storage modulus were enhanced without compromising the tensile and flexural strengths of the composites. Overall, foam composites which were prepared with longer glass fibers exhibit better mechanical and thermal properties than those prepared with shorter glass fibers due to higher interlocking between the fibers and the foam cells, which result in better load distribution in the matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polyvinyl%20chloride" title="polyvinyl chloride">polyvinyl chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=PVC%20foam" title=" PVC foam"> PVC foam</a>, <a href="https://publications.waset.org/abstracts/search?q=PVC%20composites" title=" PVC composites"> PVC composites</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20composites" title=" polymer composites"> polymer composites</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20fiber%20composites" title=" glass fiber composites"> glass fiber composites</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20polymers" title=" reinforced polymers"> reinforced polymers</a> </p> <a href="https://publications.waset.org/abstracts/18461/enhanced-dimensional-stability-of-rigid-pvc-foams-using-glass-fibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18461.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">396</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Hepatotoxicity Induced by Arsenic Trioxide in Adult Mice and Their Progeny</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bouaziz%20H.">Bouaziz H.</a>, <a href="https://publications.waset.org/abstracts/search?q=Soudania%20N."> Soudania N.</a>, <a href="https://publications.waset.org/abstracts/search?q=Essafia%20M."> Essafia M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Amara%20I."> Ben Amara I.</a>, <a href="https://publications.waset.org/abstracts/search?q=Hakim%20A."> Hakim A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamoussi%20K."> Jamoussi K.</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeghal%20Km"> Zeghal Km</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeghal%20N."> Zeghal N.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this investigation, we have evaluated the effects of arsenic trioxide on hepatic function in pregnant and lactating Swiss albino mice and their suckling pups.

Our results showed a significant decrease in plasma levels of total protein and albumin, cholesterol and triglyceride in As2O3 treated mice and their pups. The hyperbilirubinemia and the increased plasma total alkaline phosphatase activity suggested the presence of cholestasis. Transaminase activities as well as lactate deshydrogenase activity in plasma, known as biomarkers of hepatocellular injury, were elevated indicating hepatic cells’damage after treatment with As2O3. Exposure to arsenic led to an increase of liver thiobarbituric acid reactive substances level along with a concomitant decrease in the activities of superoxide dismutase, catalase and glutathione peroxidase and in glutathione. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20status" title="antioxidant status">antioxidant status</a>, <a href="https://publications.waset.org/abstracts/search?q=arsenic%20trioxide" title=" arsenic trioxide"> arsenic trioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatotoxicity" title=" hepatotoxicity"> hepatotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=mice" title=" mice"> mice</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a> </p> <a href="https://publications.waset.org/abstracts/22776/hepatotoxicity-induced-by-arsenic-trioxide-in-adult-mice-and-their-progeny" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22776.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">255</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Financial Development, Institutional Quality and Environmental Conditions in the Middle East and North Africa Region: Evidence From Oil- And Non-oil-Producing Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamel%20Boukhatem">Jamel Boukhatem</a>, <a href="https://publications.waset.org/abstracts/search?q=Semia%20Rachid"> Semia Rachid</a>, <a href="https://publications.waset.org/abstracts/search?q=Marmar%20Nasr"> Marmar Nasr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considering the differences between oil- and non-oil-producing countries, this paper aims to evaluate the impact of financial development (FD) and institutional quality (IQ) on CO2 emissions in 15 MENA (Middle East and North Africa) countries over the period 1996-2018 using the Panel ARDL approach. We found evidence to support an unconditional long run effect of FD on environmental conditions (EC), with quite significant differences between the two groups of countries. While FD leads to environmental degradation (ED) in non-oil-producing countries, it helps protect the environment in oil-producing ones. Regarding the effects of IQ on EC, they are not significant in both short- and long run for non-oil-producing countries, but they are significant for oil-producing ones only in the long run.

Therefore, the investigation of thermal-hydraulic characteristics inside the rod bundles is important for optima design and safety operation of a nuclear reactor power plant. This contribution presents a feasibility study to use the ribbed spacer grids as mixing devices. The present study evaluates the effects of different ribbed spacer grids configurations on flow pattern and heat transfer in the downstream of the mixing devices in a 2 x 2 rod bundle array. This is done by obtaining velocity and pressure fields, turbulent intensity and the heat transfer coefficient using a three-dimensional CFD analysis. Numerical calculations are performed by employing K-ε turbulent model. The computational results obtained are promising and the comparison with standard spacer grids shows a clear difference which required the experimental approach to validate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PWR%20fuel%20assembly" title="PWR fuel assembly">PWR fuel assembly</a>, <a href="https://publications.waset.org/abstracts/search?q=spacer%20grid" title=" spacer grid"> spacer grid</a>, <a href="https://publications.waset.org/abstracts/search?q=mixing%20vane" title=" mixing vane"> mixing vane</a>, <a href="https://publications.waset.org/abstracts/search?q=swirl%20flow" title=" swirl flow"> swirl flow</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20heat%20transfer" title=" turbulent heat transfer"> turbulent heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a> </p> <a href="https://publications.waset.org/abstracts/16937/feasibility-study-to-enhance-the-heat-transfer-in-a-typical-pressurized-water-reactor-by-ribbed-spacer-grids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16937.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">488</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> In vitro Cytotoxic and Genotoxic Effects of Arsenic Trioxide on Human Keratinocytes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Bouaziz">H.

Hence, the aim of the present study was to evaluate the cytotoxicity and genotoxicity induced by arsenic trioxide in human keratinocytes (HaCaT) using the MTT [3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] and alkaline single cell gel electrophoresis (Comet) assays, respectively. Human keratinocytes were treated with different doses of arsenic trioxide for 4 h prior to cytogenetic assessment. Data obtained from the MTT assay indicated that arsenic trioxide significantly reduced the viability of HaCaT cells in a dose-dependent manner, showing a IC50 value of 34.18 ± 0.6 µM. Data generated from the comet assay also indicated a significant dose-dependent increase in DNA damage in HaCaT cells associated with arsenic trioxide exposure. We observed a significant increase in comet tail length and tail moment, showing an evidence of arsenic trioxide -induced genotoxic damage in HaCaT cells. This study confirms that the comet assay is a sensitive and effective method to detect DNA damage caused by arsenic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arsenic%20trioxide" title="arsenic trioxide">arsenic trioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxixity" title=" cytotoxixity"> cytotoxixity</a>, <a href="https://publications.waset.org/abstracts/search?q=genotoxicity" title=" genotoxicity"> genotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=HaCaT" title=" HaCaT"> HaCaT</a> </p> <a href="https://publications.waset.org/abstracts/27537/in-vitro-cytotoxic-and-genotoxic-effects-of-arsenic-trioxide-on-human-keratinocytes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27537.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">257</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">27</span> Association between Neurofibromatosis Type 1 and Breast Sarcoma: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ines%20Zemni">Ines Zemni</a>, <a href="https://publications.waset.org/abstracts/search?q=Maher%20Slimane"> Maher Slimane</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamel%20Ben%20Hassouna"> Jamel Ben Hassouna</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Rahal"> Khaled Rahal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Neurofibromatosis type 1 (NF1) is a genetic disease, which is associated with an increased risk of developing different malignancies including breast cancer. The association between NF1 band breast sarcoma is a rare entity. Herein we present a 25-year-old woman with NF1 who had fibrosarcoma of the left breast. Case presentation: The patient has multiple thoraco-abdominal 'café au lait' spots. Clinical examination showed a lump of the left breast measuring 9 cm of diameter, which was noticed for 6 months. There was a left inguinal mass of 6 cm of diameter. The patient underwent first a left lumpectomy. Histopathological exam revealed a high-grade fibrosarcoma of the left breast measuring 7.5 cm. Three months later, the patient underwent a left mastectomy and excision of the inguinal mass, which was a neurofibroma. An adjuvant chemotherapy and radiation therapy were indicated, but not applied because of the timeout. The patient is now alive after a follow up of 6 years, with no loco-regional recurrence or metastasis. Conclusion: The relationship between NF1 and breast cancer need to be more clarified by further studies. Establishing a specific screening program of these patients may help to make an earlier diagnosis of breast cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurofibromatosis" title="neurofibromatosis">neurofibromatosis</a>, <a href="https://publications.waset.org/abstracts/search?q=breast" title=" breast"> breast</a>, <a href="https://publications.waset.org/abstracts/search?q=sarcoma" title=" sarcoma"> sarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a> </p> <a href="https://publications.waset.org/abstracts/103261/association-between-neurofibromatosis-type-1-and-breast-sarcoma-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103261.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">121</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">26</span> Diagnosis of Alzheimer Diseases in Early Step Using Support Vector Machine (SVM)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20Ben%20Rabeh">Amira Ben Rabeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Faouzi%20Benzarti"> Faouzi Benzarti</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Amiri"> Hamid Amiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouna%20Bouaziz"> Mouna Bouaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Alzheimer is a disease that affects the brain. It causes degeneration of nerve cells (neurons) and in particular cells involved in memory and intellectual functions. Early diagnosis of Alzheimer Diseases (AD) raises ethical questions, since there is, at present, no cure to offer to patients and medicines from therapeutic trials appear to slow the progression of the disease as moderate, accompanying side effects sometimes severe. In this context, analysis of medical images became, for clinical applications, an essential tool because it provides effective assistance both at diagnosis therapeutic follow-up. Computer Assisted Diagnostic systems (CAD) is one of the possible solutions to efficiently manage these images. In our work; we proposed an application to detect Alzheimer’s diseases. For detecting the disease in early stage we used the three sections: frontal to extract the Hippocampus (H), Sagittal to analysis the Corpus Callosum (CC) and axial to work with the variation features of the Cortex(C). Our method of classification is based on Support Vector Machine (SVM). The proposed system yields a 90.66% accuracy in the early diagnosis of the AD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%20Diseases%20%28AD%29" title="Alzheimer Diseases (AD)">Alzheimer Diseases (AD)</a>, <a href="https://publications.waset.org/abstracts/search?q=Computer%20Assisted%20Diagnostic%28CAD%29" title=" Computer Assisted Diagnostic(CAD)"> Computer Assisted Diagnostic(CAD)</a>, <a href="https://publications.waset.org/abstracts/search?q=hippocampus" title=" hippocampus"> hippocampus</a>, <a href="https://publications.waset.org/abstracts/search?q=Corpus%20Callosum%20%28CC%29" title=" Corpus Callosum (CC)"> Corpus Callosum (CC)</a>, <a href="https://publications.waset.org/abstracts/search?q=cortex" title=" cortex"> cortex</a>, <a href="https://publications.waset.org/abstracts/search?q=Support%20Vector%20Machine%20%28SVM%29" title=" Support Vector Machine (SVM)"> Support Vector Machine (SVM)</a> </p> <a href="https://publications.waset.org/abstracts/43182/diagnosis-of-alzheimer-diseases-in-early-step-using-support-vector-machine-svm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43182.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">384</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">25</span> Secure Distance Bounding Protocol on Ultra-WideBand Based Mapping Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamel%20Miri">Jamel Miri</a>, <a href="https://publications.waset.org/abstracts/search?q=Bechir%20Nsiri"> Bechir Nsiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ridha%20Bouallegue"> Ridha Bouallegue</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ultra WidBand-IR physical layer technology has seen a great development during the last decade which makes it a promising candidate for short range wireless communications, as they bring considerable benefits in terms of connectivity and mobility. However, like all wireless communication they suffer from vulnerabilities in terms of security because of the open nature of the radio channel. To face these attacks, distance bounding protocols are the most popular counter measures. In this paper, we presented a protocol based on distance bounding to thread the most popular attacks: Distance Fraud, Mafia Fraud and Terrorist fraud. In our work, we study the way to adapt the best secure distance bounding protocols to mapping code of ultra-wideband (TH-UWB) radios. Indeed, to ameliorate the performances of the protocol in terms of security communication in TH-UWB, we combine the modified protocol to ultra-wideband impulse radio technology (IR-UWB). The security and the different merits of the protocols are analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distance%20bounding" title="distance bounding">distance bounding</a>, <a href="https://publications.waset.org/abstracts/search?q=mapping%20code%20ultrawideband" title=" mapping code ultrawideband"> mapping code ultrawideband</a>, <a href="https://publications.waset.org/abstracts/search?q=terrorist%20fraud" title=" terrorist fraud"> terrorist fraud</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20layer%20technology" title=" physical layer technology"> physical layer technology</a> </p> <a href="https://publications.waset.org/abstracts/72772/secure-distance-bounding-protocol-on-ultra-wideband-based-mapping-code" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72772.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">299</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> Analysis on Heat Transfer in Solar Parabolic Trough Collectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zaid%20H.%20Yaseen">Zaid H.

There are various types of solar collectors, and parabolic trough collectors (PTCs) are common among these types. In PTCs, a mirror is used to direct the incident radiation on an absorber tube to utilize the heat in power generation. In this work, a PTC covered with a glass tube is presented and analyzed. Results showed that temperatures of 510℃ for steam can be reached for certain parameters. The work also showed the viability of using Benzene as the working fluid in the absorber tube. Also, some analysis regarding changing the absorber’s tube diameter and the efficiency of the solar collector was demonstrated in this work. The effect of changing the heat transfer correlations for the convection phenomena of the working fluid was illustrated. In fact, two heat transfer correlations, the Dittus-Boelter and Gnielinski correlations, were used, and the outcomes showed a resemblance in the results for the maximum attainable temperature in the working fluid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorber%20tube" title="absorber tube">absorber tube</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20tube" title=" glass tube"> glass tube</a>, <a href="https://publications.waset.org/abstracts/search?q=incident%20radiation" title=" incident radiation"> incident radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=parabolic%20trough%20collector" title=" parabolic trough collector"> parabolic trough collector</a> </p> <a href="https://publications.waset.org/abstracts/194511/analysis-on-heat-transfer-in-solar-parabolic-trough-collectors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194511.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">9</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> Checking Energy Efficiency by Simulation Tools: The Case of Algerian Ksourian Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khadidja%20Rahmani">Khadidja Rahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Nahla%20Bouaziz"> Nahla Bouaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Algeria is known for its rich heritage. It owns an immense historical heritage with a universal reputation. Unfortunately, this wealth is withered because of abundance. This research focuses on the Ksourian model, which constitutes a large portion of this wealth. In fact, the Ksourian model is not just a witness to a great part of history or a vernacular culture, but also it includes a panoply of assets in terms of energetic efficiency. In this context, the purpose of our work is to evaluate the performance of the old techniques which are derived from the Ksourian model , and that using the simulation tools. The proposed method is decomposed in two steps; the first consists of isolate and reintroduce each device into a basic model, then run a simulation series on acquired models. And this in order to test the contribution of each of these dialectal processes. In another scale of development, the second step consists of aggregating all these processes in an aboriginal model, then we restart the simulation, to see what it will give this mosaic on the environmental and energetic plan .The model chosen for this study is one of the ksar units of Knadsa city of Bechar (Algeria). This study does not only show the ingenuity of our ancestors in their know-how, and their adapting power to the aridity of the climate, but also proves that their conceptions subscribe in the current concerns of energy efficiency, and respond to the requirements of sustainable development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dialectal%20processes" title="dialectal processes">dialectal processes</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluation" title=" evaluation"> evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=Ksourian%20model" title=" Ksourian model"> Ksourian model</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20tools" title=" simulation tools"> simulation tools</a> </p> <a href="https://publications.waset.org/abstracts/88364/checking-energy-efficiency-by-simulation-tools-the-case-of-algerian-ksourian-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88364.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">195</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">22</span> In vivo Evidence of Protective Effect of Hyparrhenia Hirta against Nitrate-Induced Genotoxicity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Bouaziz-Ketata">H.

Hence, over the past few decades, many researchers have been emphasizing on how the teaching and learning of English as a foreign or as an additional language can best help students to perform successfully. English for specific purpose is today quite literally regarded as the most global language discipline which existed practically in every country in the world. ESP (English for Specific Purposes) involves teaching and learning the specific skills and language needed by particular learners for a particular purpose. The P in ESP is always a professional purpose which is a set of skills that learners currently need in their work or will need in their professional careers. It has had an early origin since 1960’s and has grown to become one of the most prominent of English language teaching today. Moreover, ESP learners are usually adults who have some quittances with English and learn the language so as to communicate and perform particular profession. Related activities are based on specific purposes and needs. They are integrated into subject matter area important to the learners. Unlike general English which focuses on teaching general language courses and all four language skills are equally stressed, ESP and practically needs analysis determine which language skills are the most needed by the learners and syllabus designed accordingly. This paper looked into the origin, characteristics, development of ESP, the difference between ESP and general English. Finally, the paper critically reviews the role of needs analysis in the ESP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=English%20language%20teaching" title="English language teaching">English language teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20for%20general%20purposes" title=" English for general purposes"> English for general purposes</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20for%20specific%20purposes" title=" English for specific purposes"> English for specific purposes</a>, <a href="https://publications.waset.org/abstracts/search?q=needs%20analysis" title=" needs analysis"> needs analysis</a> </p> <a href="https://publications.waset.org/abstracts/43586/english-for-specific-purposes-its-definition-characteristics-and-the-role-of-needs-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43586.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">405</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> Conversion of Atmospheric Carbone Dioxide into Minerals at Room Conditions by Using the Sea Water Plus Various Additives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muthana%20A.%20M.%20Jamel%20Al-Gburi">Muthana A.

So that will lead to global warming. The global warming affects the earth temperature causing an increase to a higher level and, at the same time, creates tornadoes and storms. In this project, we are going to do a new technique for extracting carbon dioxide directly from the air and change it to useful minerals and Nano scale fibers made of carbon by using several chemical processes through chemical reactions. So, that could lead to an economical and healthy way to make some valuable building materials. Also, it may even work as a weapon against environmental change. In our device (Carbone Dioxide Domestic Extractor), we are using Ocean-seawater to dissolve the CO₂ gas and then converted it into carbonate minerals by using a number of additives like Shampoo, clay, and MgO. Note that the atmospheric air includes CO₂ gas, has circulated within the seawater by the air pump. More, that we will use a number of chemicals agents to convert the water acid into useful minerals. After we constructed the system, we did intense experiments and investigations to find the optimum chemical agent, which must be work at the environmental condition. Further to that, we will measure the solubility of CO₂ and other salts in the seawater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title="global warming">global warming</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20gas" title=" CO₂ gas"> CO₂ gas</a>, <a href="https://publications.waset.org/abstracts/search?q=ocean-sea%20water" title=" ocean-sea water"> ocean-sea water</a>, <a href="https://publications.waset.org/abstracts/search?q=additives" title=" additives"> additives</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility%20level" title=" solubility level"> solubility level</a> </p> <a href="https://publications.waset.org/abstracts/154412/conversion-of-atmospheric-carbone-dioxide-into-minerals-at-room-conditions-by-using-the-sea-water-plus-various-additives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154412.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">111</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> Emergence of Carbapenemase Escherichia Coli Isolates from the Little Egret (Egretta Garzetta) in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bouaziz%20Amira">Bouaziz Amira</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaatout%20Nawel"> Zaatout Nawel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Antimicrobial resistance is an urgent global health challenge in human and veterinary medicine, where migratory birds play a major role in the dissemination of multi-drug-resistant bacteria. The aim of this study was to screen for the presence of carbapenemase-producing Gram-negative bacteria (GNB) in the little egret (Egrettagarzetta) migratory bird stools in Algeria. Materials/Methods: In January 2014, 12 feacal samples were collected in Garaet El-Tarf, Oum El-Bouaghi city, Algeria. Samples were subjected to selective isolation of carbapenem-resistant GNB. Representative colonies were identified using the VITEK system. The obtained isolates were subjected to antibiotic susceptibility testing using the disc-diffusion method as well as carbapenemase production was verified by the modified Carba NP test. Results: In total, ten E. coli were obtained and were resistant to amoxicillin/clavulanic acid (100%), ertapenem (70%), cefoxitin (60%) cefotaxime (20%), cefepime (20%), ciprofloxacin (20%) and aztreonam (10%). The phenotypic detection results revealed that six out of the obtained strains were positive for the modified Carba NP test. Conclusion: The present study suggests that the little egret (Egretta garzetta) could be considered a reservoir of carbapenem-resistant Gram-negative bacteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20resistance" title="antimicrobial resistance">antimicrobial resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=E.%20coli" title=" E. coli"> E. coli</a>, <a href="https://publications.waset.org/abstracts/search?q=Egretta%20garzetta" title=" Egretta garzetta"> Egretta garzetta</a>, <a href="https://publications.waset.org/abstracts/search?q=carbapenem%20resistance" title=" carbapenem resistance"> carbapenem resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=dissemination" title=" dissemination"> dissemination</a> </p> <a href="https://publications.waset.org/abstracts/194573/emergence-of-carbapenemase-escherichia-coli-isolates-from-the-little-egret-egretta-garzetta-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194573.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">7</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">18</span> Banking Performance and Political Economy: Using ARDL Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marwen%20Ghouil">Marwen Ghouil</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamel%20Eddine%20Mkadmi"> Jamel Eddine Mkadmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Banking performance is the pillar and goal of all banking activity and its impact on economic policy. First, researchers defined the principles for assessing and modeling bank performance, and then theories and models explaining bank performance were developed. The importance of credit as a means of financing businesses in most developing countries has led to questions about the effects of financial liberalisation on increased banking competition. In Tunisia, as in many other countries, the liberalization of financial services in general and of banks' activities has not ceased to evolve. The objective of this paper is to examine the determinants of banking performance for 8 Tunisian banks and their impact on economic policy during the Arab Spring. We used cointegration analysis and the ARDL Panel model, explaining using total assets, bank credits, guarantees, and bank size as performance drivers. The correlation analysis shows that there is a positive correlation relationship between total assets, bank credits, guarantees, and bank size and bank performance. Long-term empirical results show that bank loans, guarantees, bank size, and total assets have a positive and significant impact on bank performance. This means that bank credits, guarantees, bank size, and total assets are very important determinants of bank performance in Tunisia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bank%20performance" title="bank performance">bank performance</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20policy" title=" economic policy"> economic policy</a>, <a href="https://publications.waset.org/abstracts/search?q=finance" title=" finance"> finance</a>, <a href="https://publications.waset.org/abstracts/search?q=economic" title=" economic"> economic</a> </p> <a href="https://publications.waset.org/abstracts/158697/banking-performance-and-political-economy-using-ardl-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158697.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">134</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> The Effects of Interest Rates on Islamic Banks in a Dual Banking System: Empirical Evidence from Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mouldi%20Djelassi">Mouldi Djelassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamel%20Boukhatem"> Jamel Boukhatem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: A relation has been established between Islamic banks' activities and interest rates. The aim of this study was to explore the impact of interest rates on the deposits and loans held by Islamic and conventional banks in Saudi Arabia. Methods: A time series data was performed over the period 2008Q1-2020Q2 on eight conventional banks and four Islamic banks. The impacts of interest rate shocks on deposits and loans were identified through panel vector autoregressive models. Results: Impulse response function analysis showed that increasing interest rates reduce loans and conventional deposits. For Islamic banks, deposits are more affected by interest rates than lending. Variance decomposition analysis revealed that deposits contribute to 61% of the Islamic financing variation and only 25% of the conventional loans. Conclusion: Interest rates impacted Islamic banks especially through deposits, which is inconsistent with the theoretical framework. Islamic deposits played an important role in Islamic financing variation and may provide to be a channel for the transmission of the monetary policy in a dual banking system. Monetary policy in Saudi Arabia works in part through “credits” (conventional bank credits) as well as through “money” (conventional and Islamic bank deposits). <p
