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">45</span> Fuzzy Semantic Annotation of Web Resources </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Ma%C3%A2lej%20Dammak">Sahar Maâlej Dammak</a>, <a href="https://publications.waset.org/abstracts/search?q=Anis%20Jedidi"> Anis Jedidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafik%20Bouaziz"> Rafik Bouaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the great mass of pages managed through the world, and especially with the advent of the Web, their manual annotation is impossible.

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.

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.

In this work we study the electronic and optical properties of Cu2SnS3. For this purpose we used the Wien2k code based on the theory of density functional theory (DFT) with the modified Becke-Johnson exchange potential mBJ and the Hubbard potential individually or combined. We have found an energy gap 0.92 eV. The results are in good agreement with experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cu2SnS3" title="Cu2SnS3">Cu2SnS3</a>, <a href="https://publications.waset.org/abstracts/search?q=DFT" title=" DFT"> DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20and%20optical%20properties" title=" electronic and optical properties"> electronic and optical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=mBJ%2BU" title=" mBJ+U"> mBJ+U</a>, <a href="https://publications.waset.org/abstracts/search?q=WIEN2K" title=" WIEN2K"> WIEN2K</a> </p> <a href="https://publications.waset.org/abstracts/18915/dft-study-of-secondary-phase-of-cu2znsns4-in-solar-cell-cu2sns3" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18915.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">559</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">36</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">35</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.

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">31</span> Estimation of the State of Charge of the Battery Using EFK and Sliding Mode Observer in MATLAB-Arduino/Labview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mouna%20Abarkan">Mouna Abarkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelillah%20Byou"> Abdelillah Byou</a>, <a href="https://publications.waset.org/abstracts/search?q=Nacer%20M%27Sirdi"> Nacer M'Sirdi</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Hossain%20Abarkan"> El Hossain Abarkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the estimation of the state of charge of the battery using two types of observers.

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">29</span> Optimization of a Combined Ejector-Vapor Compression Refrigeration Systems with R134a</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilhem%20Ouelhazi">Ilhem Ouelhazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouna%20Elakhdar"> Mouna Elakhdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Lakdar%20Kairouani"> Lakdar Kairouani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A computer simulation model for a combined ejector-vapor compression cycle that uses working fluid R134a.

The objective of this study was to evaluate the influence of drying in the shade on the water content and on the content of essential oils extracted from leaves of Eucalyptus camendulensis for better quality control of medicinal and aromatic plants. The water content of the Eucalyptus camendulensis plant material decreases during the drying process. It increased from 100 % to 0.006 % for the drying in the shade after ten days. The moisture content is practically constant at the end of the drying period. The drying in the shade increases the concentration of essential oils of Eucalyptus camendulensis. When the leaves of Eucalyptus camendulensis plant are in the shade, the maximum of the essential oil content was obtained on the eighth days; the recorded value was 1.43% ± 0.01%. Beyond these periods, the content continuously drops in before stabilizing.

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">26</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">25</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.

Male Wistar rats were randomly divided into three groups: a control group and two treated groups during 50 days with NaNO3 administered at a dose of 400 mg kg-1 bw either alone in drinking water or co-administered with Hyparrhenia hirta at a dose of 200 mg kg-1 bw. NaNO3 treatment showed a significant increase in the frequencies of total chromosomal aberrations, aberrant metaphases and micronucleus in bone-marrow cells. In parallel, the NaNO3-treated group showed a significant decrease in red blood cell count, hemoglobin and hematocrit and a significant increase in total white blood cell, in neutrophil and eosinophil counts. Platelet count, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration remained unchanged in treated groups compared to those of controls.

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">23</span> English for Specific Purposes: Its Definition, Characteristics, and the Role of Needs Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karima%20Tayaa">Karima Tayaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Bouaziz"> Amina Bouaziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rapid expansion in the scientific fields and the growth of communication technology increased the use of English as international language in the world. 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">22</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">21</span> Improving Comfort and Energy Mastery: Application of a Method Based on Indicators Morpho-Energetic</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> The climate change and the economic crisis, which are currently running, are the origin of the emergence of many issues and problems, which are related to the domain of energy and environment in à direct or indirect manner. Since the urban space is the core element and the key to solve the current problem, particular attention is given to it in this study. For this reason, we rented to the later a very particular attention; this is for the opportunities that it provides and that can be invested to attenuate a little this situation, which is disastrous and worried, especially in the face of the requirements of sustainable development. Indeed, the purpose of this work is to develop a method, which will allow us to guide designers towards projects with a certain degree of thermo-aeraulic comfort while requiring a minimum energy consumption. In this context, the architects, the urban planners and the engineers (energeticians) have to collaborate jointly to establish a method based on indicators for the improvement of the urban environmental quality (aeraulic-thermo comfort), correlated with a reduction in the energy demand of the entities that make up this environment, in areas with a sub-humid climate. In order to test the feasibility and to validate the method developed in this work, we carried out a series of simulations using computer-based simulation. This research allows us to evaluate the impact of the use of the indicators in the design of the urban sets, on the economic and ecological plan. Using this method, we prove that an urban design, which carefully considered energetically, can contribute significantly to the preservation of the environment and the reduction of the consumption of energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comfort" title="comfort">comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20mastery" title=" energy mastery"> energy mastery</a>, <a href="https://publications.waset.org/abstracts/search?q=morpho-energetic%20indicators" title=" morpho-energetic indicators"> morpho-energetic indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-humid%20climate" title=" sub-humid climate"> sub-humid climate</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20sets" title=" urban sets"> urban sets</a> </p> <a href="https://publications.waset.org/abstracts/88143/improving-comfort-and-energy-mastery-application-of-a-method-based-on-indicators-morpho-energetic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88143.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Microbiological Study of Two Spontaneous Plants of Algerian Sahara Septentrional: Cotula cinerea and Chamomilla recutita</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehani%20Mouna">Mehani Mouna</a>, <a href="https://publications.waset.org/abstracts/search?q=Boukhari%20Nadjet"> Boukhari Nadjet</a>, <a href="https://publications.waset.org/abstracts/search?q=Ladjal%20Segni"> Ladjal Segni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of our study is to determine the antimicrobial effect of essential oils of two plants Cotula cinerea and Chamomilla recutita on some pathogenic bacteria.

This waste can be used as a secondary resource to recover high purity silicon which has a great economic value. From the management perspective, the ever increasing generation of kerf slurry waste loss leads to significant challenges for the photovoltaic industry due to the current low use of slurry waste for silicon recovery. Slurry waste, in most cases, contains silicon, silicon carbide, metal fragments and mineral-oil-based or glycol-based slurry vehicle. As a result, of the global scarcity of high purity silicon supply, the high purity silicon content in slurry has increasingly attracted interest for research. This paper presents a critical overview of the current techniques employed for high purity silicon recovery from kerf slurry waste. Hydrometallurgy is continuously a matter of study and research. However, in this review paper, several new techniques about the process of high purity silicon recovery from slurry waste are introduced.

This type of technology is supported in many teaching/learning setting where the medium of instruction is through computer technology, and particularly involving digital technologies. There has been much debate over the use of computers and the internet in foreign language teaching for more than two decades. Various studies highlights that the integration of Information Communications Technology (ICT) in foreign language teaching will have positive effects on both the teachers and students to help them be aware of the modernized world and meet the current demands of the globalised world. Information and communication technology has been gradually integrated in foreign learning environment as a platform for providing learners with learning opportunities. Thus, the impact of ICT on language teaching and learning has been acknowledged globally, this is because of the fundamental role that it plays in the enhancement of teaching and learning quality, modify the pedagogical practice, and motivate learners. Due to ICT related developments, many Maghreb countries regard ICT as a tool for changes and innovations in education. Therefore, the ministry of education attempted to set up computer laboratories and provide internet connection in the schools. Investment in ICT for educational innovations and improvement purposes has been continuing the need of teacher who will employ it in the classroom as vital role of the curriculum. ICT does not have an educational value in itself, but it becomes precious when teachers use it in learning and teaching process. This paper examines the impacts of ICT on teacher development rather than on teaching quality and highlights some challenges facing using ICT in the language learning/teaching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20communications%20technology%20%28ICT%29" title="information communications technology (ICT)">information communications technology (ICT)</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20language%20teaching" title=" foreign language teaching"> foreign language teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20development" title=" teacher development"> teacher development</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20opportunity" title=" learning opportunity"> learning opportunity</a> </p> <a href="https://publications.waset.org/abstracts/43919/the-integration-of-ict-in-efl-classroom-and-its-impact-on-teacher-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43919.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">388</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> Antimicrobial Effect of Essential Oil of Plant Schinus molle on Some Bacteria Pathogens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehani%20Mouna">Mehani Mouna</a>, <a href="https://publications.waset.org/abstracts/search?q=Ladjel%20segni"> Ladjel segni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Humans use plants for thousands of years to treat various ailments, In many developing countries, Much of the population relies on traditional doctors and their collections of medicinal plants to cure them. Essential oils have many therapeutic properties. In herbal medicine, They are used for their antiseptic properties against infectious diseases of fungal origin, Against dermatophytes, Those of bacterial origin. The aim of our study is to determine the antimicrobial effect of essential oils of the plant Schinus molle on some pathogenic bacteria. It is a medicinal plant used in traditional therapy. Essential oils have many therapeutic properties. In herbal medicine, They are used for their antiseptic properties against infectious diseases of fungal origin, Against dermatophytes, Those of bacterial origin. The test adopted is based on the diffusion method on solid medium (Antibiogram), This method allows to determine the susceptibility or resistance of an organism according to the sample studied. Our study reveals that the essential oil of the plant Schinus molle has a different effect on the resistance of germs: For Pseudomonas aeruginosa strain is a moderately sensitive with an inhibition zone of 10 mm, Further Antirobactere, Escherichia coli and Proteus are strains that represent a high sensitivity, A zone of inhibition equal to 14.66 mm. <p
