This was achieved by exploring the interesting properties of conductive (Mg/Al) layered double hydroxide- Dodecyl Sulphate/Polypyrrole nanocomposites which were synthesized by in-situ polymerization of pyrrole during the assembly of (Mg/Al) layered double hydroxide, and by employing the anionic surfactant Dodecyl sulphate as a modifier. The morphology and surface area of the nanocomposites changed with the percentage of Pyrrole. Under optimal conditions, the modified carbon paste electrode successfully achieved detection limits of 0.057 and 0.134 nmol.L-1 of Terazosin hydrochloride in pharmaceutical formulation and spiked human serum fluid, respectively. Moreover, the sensors are highly stable, reusable, and free from interference by other commonly present excipients in drug formulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=layered%20double%20hydroxide" title="layered double hydroxide">layered double hydroxide</a>, <a href="https://publications.waset.org/abstracts/search?q=polypyrrole" title=" polypyrrole"> polypyrrole</a>, <a href="https://publications.waset.org/abstracts/search?q=terazosin%20hydrochloride" title=" terazosin hydrochloride"> terazosin hydrochloride</a>, <a href="https://publications.waset.org/abstracts/search?q=square-wave%20adsorptive%20anodic%20stripping%20voltammetry" title=" square-wave adsorptive anodic stripping voltammetry"> square-wave adsorptive anodic stripping voltammetry</a> </p> <a href="https://publications.waset.org/abstracts/79856/fabrication-of-biosensor-based-on-layered-double-hydroxidepolypyrrolecarbon-paste-electrode-for-determination-of-anti-hypertensive-and-prostatic-hyperplasia-drug-terazosin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79856.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">110</span> Concrete Recycling in Egypt for Construction Applications: A Technical and Financial Feasibility Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Farahat%20Hassanein">Omar Farahat Hassanein</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Samer%20Ezeldin"> A.

Every day new technologies and methods are developing to fasten the process and increase its efficiency. Hence, if a project uses fewer resources, it will be more efficient. This paper examines the recycling of concrete construction and demolition (C&D) waste to reuse it as aggregates in on-site applications for construction projects in Egypt and possibly in the Middle East. The study focuses on a stationary plant setting. The machinery set-up used in the plant is analyzed technically and financially. The findings are gathered and grouped to obtain a comprehensive cost-benefit financial model to demonstrate the feasibility of establishing and operating a concrete recycling plant. Furthermore, a detailed business plan including the time and hierarchy is proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20wastes" title="construction wastes">construction wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling" title=" recycling"> recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20model" title=" financial model"> financial model</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20recycling" title=" concrete recycling"> concrete recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20life%20cycle" title=" concrete life cycle"> concrete life cycle</a> </p> <a href="https://publications.waset.org/abstracts/3051/concrete-recycling-in-egypt-for-construction-applications-a-technical-and-financial-feasibility-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3051.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">416</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">109</span> Comparative Assessment of ISSR and RAPD Markers among Egyptian Jojoba Shrubs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelsabour%20G.%20A.%20Khaled">Abdelsabour G.

In order to estimate the genetic diversity, molecular markers provided excellent tools. In this study, Genetic variation of nine Egyptian jojoba shrubs was tested using ISSR (inter simple sequences repeats), RAPD (random amplified polymorphic DNA) markers and based on the morphological characterization. The average of the percentage of polymorphism (%P) ranged between 58.17% and 74.07% for ISSR and RAPD markers, respectively. The range of genetic similarity percents among shrubs based on ISSR and RAPD markers were from 82.9 to 97.9% and from 85.5 to 97.8%, respectively. The average of PIC (polymorphism information content) values were 0.19 (ISSR) and 0.24 (RAPD). In the present study, RAPD markers were more efficient than the ISSR markers. Where the RAPD technique exhibited higher marker index (MI) average (1.26) compared to ISSR one (1.11). There was an insignificant correlation between the ISSR and RAPD data (0.076, P > 0.05). The dendrogram constructed by the combined RAPD and ISSR data gave a relatively different clustering pattern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation" title="correlation">correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20markers" title=" molecular markers"> molecular markers</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=marker%20index" title=" marker index"> marker index</a> </p> <a href="https://publications.waset.org/abstracts/22213/comparative-assessment-of-issr-and-rapd-markers-among-egyptian-jojoba-shrubs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22213.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">478</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">108</span> Faculty and Students Perspectives of E-Learning at the University of Bahrain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20Abdulrazzaq">Amira Abdulrazzaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is studying the opinion of faculty members and students about the future of education (e-learning) at the University of Bahrain.

The proposed topology based on the series-parallel half-bridge resonant inverter is described. It can operate with Zero-Voltage Switching (ZVS). At the resonant frequency, the secondary current is amplified over the heating coil with small switching angle, which keeps the reactive power low and permits heating with small current through the resonant inductor and the transformer. The operation and control principle of the proposed high frequency inverter is described and verified through simulated and experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20heating" title="induction heating">induction heating</a>, <a href="https://publications.waset.org/abstracts/search?q=inverter" title=" inverter"> inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20frequency" title=" high frequency"> high frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=resonant" title=" resonant"> resonant</a> </p> <a href="https://publications.waset.org/abstracts/8100/high-frequency-half-bridge-inverter-applied-to-induction-heating" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8100.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">464</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">102</span> Moral Hazard under the Effect of Bailout and Bailin Events: A Markov Switching Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20Kaddour">Amira Kaddour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To curb the problem of liquidity in times of financial crises, two cases arise; the Bailout or Bailin, two opposite choices that elicit the analysis of their effect on moral hazard.

Collective competence is becoming crucial in developing and maintaining a firm’s competitive advantage, as well as its contributions to organizational innovation. In other words, the improvement of collective competence for a firm is no longer a choice, but rather an obligation. Learning capabilities of a firm in the context of knowledge management are assumed to be the main drivers of collective competence. Although there are some efforts to consider these concepts together; they are mostly discussed separately in the management theory. Thus, this paper aims to offer a holistic approach for development collective competence on the basis of Knowledge Management and Organizational Learning Capabilities. A theoretical model that defines a relationship between knowledge management, organizational learning and collective competence is presented at the end of this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collective%20competence" title="collective competence">collective competence</a>, <a href="https://publications.waset.org/abstracts/search?q=exploitation%20learning" title=" exploitation learning"> exploitation learning</a>, <a href="https://publications.waset.org/abstracts/search?q=exploration%20learning" title=" exploration learning"> exploration learning</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title=" knowledge management"> knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20learning%20capabilities" title=" organizational learning capabilities"> organizational learning capabilities</a> </p> <a href="https://publications.waset.org/abstracts/19352/the-link-between-knowledge-management-organizational-learning-and-collective-competence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19352.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">507</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">96</span> Protein-Thiocyanate Composite as a Sensor for Iron III Cations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hosam%20El-Sayed">Hosam El-Sayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20%20Abou%20El-Kheir"> Amira Abou El-Kheir</a>, <a href="https://publications.waset.org/abstracts/search?q=Salwa%20Mowafi"> Salwa Mowafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Abou%20Taleb"> Marwa Abou Taleb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two proteinic biopolymers; namely keratin and sericin, were extracted from their respective natural resources by simple appropriate methods.

The idea of this task was imagined as an extension of a previous area called multi-document summarization (MDS), which consists in generating a summary from many sources. In both TC and MDS, the summary should ideally contain the most relevant information of the topic that is being discussed in the source texts (for MDS) and related to the query (for TC). Furthermore of being informative, a summary should be coherent, i.e. well written to be readable and grammatically compact. Hence, coherence is an essential characteristic in order to produce comprehensible texts. In this paper, we propose a new approach to improve readability and coherence for tweet contextualization based on bipartite graphs. The main idea of our proposed method is to reorder sentences in a given paragraph by combining most expressive words detection and HITS (Hyperlink-Induced Topic Search) algorithm to make up a coherent context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bipartite%20graphs" title="bipartite graphs">bipartite graphs</a>, <a href="https://publications.waset.org/abstracts/search?q=readability" title=" readability"> readability</a>, <a href="https://publications.waset.org/abstracts/search?q=summarization" title=" summarization"> summarization</a>, <a href="https://publications.waset.org/abstracts/search?q=tweet%20contextualization" title=" tweet contextualization"> tweet contextualization</a> </p> <a href="https://publications.waset.org/abstracts/87337/improoving-readability-for-tweet-contextualization-using-bipartite-graphs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87337.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">194</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">91</span> Hepatoprotective Effect of Mycophenolate Mofetil against Tacrolimus Exposure in Rat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ferjani%20Hanen">Ferjani Hanen</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Arem%20Amira"> El Arem Amira</a>, <a href="https://publications.waset.org/abstracts/search?q=Boussema%20Ayed%20Imen"> Boussema Ayed Imen</a>, <a href="https://publications.waset.org/abstracts/search?q=Bacha%20Hassen"> Bacha Hassen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tacrolimus (TAC), a calcineurin inhibitor, is clinically used as an immunosuppressive agent in the transplant recipient, but its use associated-hepatotoxicity. Mycophenolate mofetil (MMF), an anti-metabolite, is a potent immunosuppressive drug. MMF is not hepatotoxic and is the most common adjunctive immunosuppressant for TAC. The effects of TAC and MMF combination in the liver is still not well understood. This work aimed to investigate their combined effect against in liver in rats Wistar after 24 h. The oral median lethal doses (LD50) of TAC and MMF alone were evaluated in rats are 240 mg/kg and 500 mg/kg respectively. Oral administration of the MMF at 50 mg/kg to male Wistar intoxicated with TAC at 60 mg/kg, demonstrated a significant protective effect by lowering the levels of hepatic markers enzymes (AST, ALT) in the serum rat. MMF attenuated oxidative stress by restoring the activities of SOD, CAT and by reducing the malondialdehyde (MDA) and protein carbonyl levels liver. This study provided evidence that MMF protects rat liver from TAC-induced injury and suggests a most combination use for organ transplantation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tacrolimus" title="tacrolimus">tacrolimus</a>, <a href="https://publications.waset.org/abstracts/search?q=mycophenolate%20mofetil" title=" mycophenolate mofetil"> mycophenolate mofetil</a>, <a href="https://publications.waset.org/abstracts/search?q=combination" title=" combination"> combination</a>, <a href="https://publications.waset.org/abstracts/search?q=liver" title=" liver"> liver</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a> </p> <a href="https://publications.waset.org/abstracts/26359/hepatoprotective-effect-of-mycophenolate-mofetil-against-tacrolimus-exposure-in-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26359.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">336</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">90</span> Reduction of High-Frequency Planar Transformer Conduction Losses Using a Planar Litz Wire Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Belloumi">Hamed Belloumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Zouaoui"> Amira Zouaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferid%20kourda"> Ferid kourda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new trend in power converters is to design planar transformer that aim for low profile.

The results which obtained indicate that the 4g/L biochar dose is the most efficient in terms of nitrates removal in aqueous solution. The biochar exhibited a good affinity for nitrates after 1hour of contact. The yield of removal of nitrate by the biochar decreases with the increase of pH of the solution and increases with increasing temperature (60°C>40°C>20°C). The best removal yield is about 80% of the initial concentration introduced (25mg/L) obtained at pH=2, T=60°C, and dose of biochar=4g/L. The second order model fit the nitrate adsorption kinetics of biochar with a high coefficient of determination (R2≥0.997); and a new equation correlating the rate constant of the reaction with temperature and pH was been built. Freundlich isotherms performed well to fit the nitrate adsorption data by biochar (R2>0.96) compared to Langmuir isotherms. The thermodynamic parameters (ΔH°, ΔG°, ΔS°) have been calculated for predicting the nature of adsorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pollution" title="pollution">pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=biochar" title=" biochar"> biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrate" title=" nitrate"> nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a> </p> <a href="https://publications.waset.org/abstracts/156278/kinetic-and-thermodynamic-study-of-nitrates-removal-by-sorption-on-biochar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156278.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">95</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">87</span> Performativity and Valuation Techniques: Evidence from Investment Banks in the Wake of the Global Financial Crisis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alicja%20Reuben">Alicja Reuben</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Annabi"> Amira Annabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we explore the relationship between the selection of valuation techniques by investment banks and the banks’ risk perceptions and performance in the context of the theory of performativity. We use inferential statistics to study these relationships by building a unique dataset based on the disclosure of 12 investment banks’ 2012-2015 annual financial statements. Moreover, we create two constructs, namely intensity of use and risk perception. We measure the intensity of use as a frequency metric of how often a particular bank adopts valuation techniques for a particular asset or liability. We measure risk perception based on disclosed ranges of values for unobservable inputs. Our results are twofold: we find a significant negative correlation between (1) intensity of use and investment bank performance and (2) intensity of use and risk perception. These results indicate that a performative process takes place, and the valuation techniques are enacting their environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=language" title="language">language</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistics" title=" linguistics"> linguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=performativity" title=" performativity"> performativity</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20techniques" title=" financial techniques"> financial techniques</a> </p> <a href="https://publications.waset.org/abstracts/116825/performativity-and-valuation-techniques-evidence-from-investment-banks-in-the-wake-of-the-global-financial-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116825.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">160</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">86</span> Islamic Finance in Tunisia: Reality and Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20Kaddour">Amira Kaddour</a>, <a href="https://publications.waset.org/abstracts/search?q=Hedia%20Teraoui"> Hedia Teraoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Khmayes%20Bougatef"> Khmayes Bougatef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this paper is to determine the major causes of the underdevelopment of Islamic finance in Tunisia. Indeed, it’s surprising to note that Zitouna bank established in May 2010 is the first Islamic Tunisian bank although 99% of Tunisians are Muslim and Islam is the religion of the State according to the Constitution. So we rely in our paper on the opinions of number of professors of finance and economics as educated people to prove or reject our hypothesis that the underdevelopment of Islamic finance in Tunisia can be explained by the ignorance of its main principles and advantages. Ours findings reveal that this branch of finance is still largely unknown, not only from public but also from professionals. The results obtained surprisingly show that this insignificance of Islamic banking cannot be explained by the fact that Tunisia has been governed since its independence by a secular left-wing party. Indeed, only 3% of respondents believe that legislation and regulation in Tunisia represent an obstacle to the development of Islamic finance. Moreover, respondents are not very optimistic about the future role of Islamic financing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banking" title="Islamic banking">Islamic banking</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20insurance%20%28takaful%29" title=" Islamic insurance (takaful)"> Islamic insurance (takaful)</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20law%20%28shariah%29" title=" Islamic law (shariah)"> Islamic law (shariah)</a>, <a href="https://publications.waset.org/abstracts/search?q=usury%20%28riba%29" title=" usury (riba)"> usury (riba)</a> </p> <a href="https://publications.waset.org/abstracts/6104/islamic-finance-in-tunisia-reality-and-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6104.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">365</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">85</span> Premature Departure of Active Women from the Working World: One Year Retrospective Study in the Tunisian Center</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Bouzgarrou">Lamia Bouzgarrou</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Omrane"> Amira Omrane</a>, <a href="https://publications.waset.org/abstracts/search?q=Malika%20%20Azzouzi"> Malika Azzouzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Kheder"> Asma Kheder</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Saadallah"> Amira Saadallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilhem%20Boussarsar"> Ilhem Boussarsar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamel%20Rejeb"> Kamel Rejeb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Increasing the women’s labor force participation is a political issue in countries with developed economies and those with low growth prospects. However, in the labor market, women continue to face several obstacles, either for the integration or for the maintenance at work. This study aims to assess the prevalence of premature withdrawal from working life -due to invalidity or medical justified early retirement- among active women in the Tunisian center and to identify its determinants. Material and methods: We conducted a cross-sectional study, over one year, focusing on the agreement for invalidity or early retirement for premature usury of the body- delivered by the medical commission of the National Health Insurance Fund (CNAM) in the central Tunisian district. We exhaustively selected women's files. Data related to Socio-demographic characteristics, professional and medical ones, were collected from the CNAM's administrative and medical files. Results: During the period of one year, 222 women have had an agreement for premature departure of their professional activity. Indeed, 149 women (67.11%) benefit of from invalidity agreement and 20,27% of them from favorable decision for early retirement. The average age was 50 ± 6 years with extremes of 23 and 62 years, and 18.9% of women were under 45 years. Married women accounted for 69.4% and 59.9% of them had at least one dependent child in charge. The average professional seniority in the sector was 23 ± 8 years. The textile-clothing sector was the most affected, with 70.7% of premature departure. Medical reasons for withdrawal from working life were mainly related to neuro-degenerative diseases in 46.8% of cases, rheumatic ones in 35.6% of cases and cardiovascular diseases in 22.1% of them. Psychiatric and endocrine disorders motivated respectively 17.1% and 13.5% of these departures. The evaluation of the sequels induced by these pathologies concluded to an average permanent partial disability equal to 61.4 ± 17.3%. The analytical study concluded that the agreement of disability or early retirement was correlated with the insured ‘age (p = 10-3), the professional seniority (p = 0.003) and the permanent partial incapacity (PPI) rate assessed by the expert physician (p = 0.04). No other social or professional factors were correlated with this decision. Conclusion: Despite many advances in labour law and Tunisian legal text on employability, women still exposed to several social and professional inequalities (payment inequality, precarious work ...). Indeed, women are often pushed to accept working in adverse conditions, thus they are more vulnerable to develop premature wear on the body and being forced to premature departures from the world of work. These premature withdrawals from active life are not only harmful to the concerned women themselves, but also associated with considerable costs for the insurance organism and the society. In order to ensure maintenance at work for women, a political commitment is imperative in the implementation of global prevention strategies and the improvement of working conditions, particularly in our socio-cultural context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Active%20Women" title="Active Women ">Active Women </a>, <a href="https://publications.waset.org/abstracts/search?q=Early%20Retirement" title=" Early Retirement "> Early Retirement </a>, <a href="https://publications.waset.org/abstracts/search?q=Invalidity" title=" Invalidity "> Invalidity </a>, <a href="https://publications.waset.org/abstracts/search?q=Maintenance%20at%20Work" title=" Maintenance at Work"> Maintenance at Work</a> </p> <a href="https://publications.waset.org/abstracts/96525/premature-departure-of-active-women-from-the-working-world-one-year-retrospective-study-in-the-tunisian-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96525.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">152</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">84</span> Psychiatric Nurses&#039; Perception of Patient Safety Culture: A Qualitative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20A.%20Alshowkan">Amira A.

However, studies that compare between the effectiveness of the language production when using TBLT versus FFI are very little with results that are not consistent. Moreover, teaching Arabic using TBLT is a new field with few research that has investigated its application inside classrooms. Furthermore, to the best knowledge of the researcher, there are no prior studies that compared teaching Arabic as a foreign language in a classroom setting using computer-assisted task-based language teaching (CATBLT) with computer-assisted form focused language instruction (CAFFI). Accordingly, the focus of this presentation is to display CATBLT and CAFFI tools when teaching Arabic as a foreign language as well as demonstrate an experimental study that aims to identify whether or not CATBLT is a more effective instruction method. The effectiveness will be determined through comparing CATBLT and CAFFI in terms of accuracy, lexical complexity, and fluency of language produced by students. The participants of the study are 20 students enrolled in two intermediate-level Arabic as a foreign language classes. The experiment will take place over the course of 7 days. Based on a study conducted by Abdurrahman Arslanyilmaz for teaching Turkish as a second language, an in-house computer assisted tool for the TBLT and another one for FFI will be designed for the experiment. The experimental group will be instructed using the in-house CATBLT tool and the control group will be taught through the in-house CAFFI tool. The data that will be analyzed are the dialogues produced by students in both the experimental and control groups when completing a task or communicating in conversational activities. The dialogues of both groups will be analyzed to understand the effect of the type of instruction (CATBLT or CAFFI) on accuracy, lexical complexity, and fluency. Thus, the study aims to demonstrate whether or not there is an instruction method that positively affects the language produced by students learning Arabic as a foreign language more than the other. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20assisted%20language%20teaching" title="computer assisted language teaching">computer assisted language teaching</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=form-focused%20instruction" title=" form-focused instruction"> form-focused instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=task%20based%20language%20teaching" title=" task based language teaching"> task based language teaching</a> </p> <a href="https://publications.waset.org/abstracts/79009/a-case-study-comparing-the-effect-of-computer-assisted-task-based-language-teaching-and-computer-assisted-form-focused-language-instruction-on-language-production-of-students-learning-arabic-as-a-foreign-language" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79009.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">252</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">82</span> Performance Evaluation of Different Technologies of PV Modules in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20Balaska">Amira Balaska</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Tahri"> Ali Tahri</a>, <a href="https://publications.waset.org/abstracts/search?q=Amine%20Boudghene%20Stambouli"> Amine Boudghene Stambouli</a>, <a href="https://publications.waset.org/abstracts/search?q=Takashi%20Oozeki"> Takashi Oozeki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is dealing with the evaluation of photovoltaic modules as part of the Sahara Solar Breeder project (SSB), five different photovoltaic module technologies which are: m-si, CIS, HIT, Back Contact, a-si_μc -si and a weather station recently installed at the University of Saida (Tahar Moulay) in Saida city located at the gate of the great southern Algeria’s Sahara. The objective of the present work is the study of solar photovoltaic capacity and performance parameters of each PV module technology. The goal of the study is to compare the five different PV technologies in order to find which technologies are suitable for the climate conditions of Algeria’s desert. Measurements of various parameters as irradiance, temperature, humidity and so on by the weather station and I-V curves were performed outdoors at the location without shadow. Finally performance parameters as performance ratio, energy yield and temperature losses are given and analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20modules" title="photovoltaic modules">photovoltaic modules</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20ratio" title=" performance ratio"> performance ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20yield" title=" energy yield"> energy yield</a>, <a href="https://publications.waset.org/abstracts/search?q=sahara%20solar%20breeder" title=" sahara solar breeder"> sahara solar breeder</a>, <a href="https://publications.waset.org/abstracts/search?q=outdoor%20conditions" title=" outdoor conditions"> outdoor conditions</a> </p> <a href="https://publications.waset.org/abstracts/27239/performance-evaluation-of-different-technologies-of-pv-modules-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27239.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">662</span> </span> </div> </div> <ul class="pagination"> <li class="page-item disabled"><span class="page-link">&lsaquo;</span></li> <li class="page-item active"><span class="page-link">1</span></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Amira%20M.%20Hassanein&amp;page=2">2</a></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Amira%20M.%20Hassanein&amp;page=3">3</a></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Amira%20M.%20Hassanein&amp;page=4">4</a></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Amira%20M.%20Hassanein&amp;page=2" rel="next">&rsaquo;</a></li> </ul> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">&copy;
