(amphotericin B, econazole, ketoconazole and miconazole) on MDA-Kb2 cell lines. This biological model is an effective tool for the detection of endocrine disruptors because it responds well to the main agonist of the androgen receptor (testosterone) and also to an antagonist: flutamide. The cytotoxicity of each chemical compound tested was measured using an MTT assay (tetrazolium salt, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) which measures the activity of the reductase function of mitochondrial succinate dehydrogenase enzymes of cultured cells. This complementary cytotoxicity test is essential to ensure that the effects of reduction in luminescence intensity observed during androgenic tests are only attributable to the anti-androgenic action of the compounds tested and not to their possible cytotoxic properties. Tests of the androgenic activity of antifungals show that these compounds do not have the capacity to induce transcription of the luciferase gene. These compounds do not exert an androgenic effect on MDA-Kb2 cells in culture for the environmental concentrations tested. The addition of flutamide for the same tested concentrations of antifungal molecules reduces the luminescence induced by amphotericin B, econazole and miconazole, which is explained by a strong interaction of these molecules with flutamide which may have a greater toxic effect than when tested alone. The cytotoxicity test shows that econazole and ketoconazole can cause cell death at certain concentrations tested. This cell mortality is perhaps induced by a direct or indirect action on deoxyribonucleic acid (DNA), ribonucleic acid (RNA) or proteins necessary for cell division. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cytotoxicity" title="cytotoxicity">cytotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=androgenic%20potential" title=" androgenic potential"> androgenic potential</a>, <a href="https://publications.waset.org/abstracts/search?q=antifungals" title=" antifungals"> antifungals</a>, <a href="https://publications.waset.org/abstracts/search?q=MDA-Kb2" title=" MDA-Kb2"> MDA-Kb2</a> </p> <a href="https://publications.waset.org/abstracts/186088/cytotoxicity-and-androgenic-potential-of-antifungal-drug-substances-on-mda-kb2-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186088.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">48</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">106</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.

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">94</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">89</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">88</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.

And to perceive the phenomenon of Ratcheting leading to the damage of LCP by an excess of plastic deformation under nonsymmetrical alternated imposed constraint in low cycle fatigue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=316L%20SS" title="316L SS">316L SS</a>, <a href="https://publications.waset.org/abstracts/search?q=locking%20compression%20plate" title=" locking compression plate"> locking compression plate</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20cycle%20fatigue" title=" low cycle fatigue"> low cycle fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=ratcheting" title=" ratcheting"> ratcheting</a> </p> <a href="https://publications.waset.org/abstracts/182140/damage-to-lcp-by-the-ratcheting-phenomenon-under-cyclic-motion-in-oligocyclic-fatigue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182140.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">63</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> Kinetic and Thermodynamic Study of Nitrates Removal by Sorption on Biochar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amira%20Touil">Amira Touil</a>, <a href="https://publications.waset.org/abstracts/search?q=Achouak%20Arfaoui"> Achouak Arfaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibtissem%20Mannaii"> Ibtissem Mannaii</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this work is to monitor the process adsorption of nitrates by the biochar via studying the influence of various parameters on the adsorption of this pollutant by biochar in a synthetic aqueous solution. 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">85</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">84</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">366</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">83</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">82</span> Psychiatric Nurses' 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.

Through the examples and the experiences presented, the remark which can be made, is that in the traditional built, two major principles in a way opposite, govern the constructions in earthquake-resistant. It is about the very big flexibility, whom answer very light constructions, like the Japanese wooden constructions, Turkish and even Chinese; that of the very big rigidity to which correspond constructions in masonry in particular stone, more or less heavy and massive, which we meet in particular in the Mediterranean Basin, and in the historic sanctuary of Machu Pacchu.

Its spreading has not been fully elucidated. Information on sandfly vectors, as well as their associated Leishmania species, is of paramount importance since vector dispersion is one of the major factors responsible for pathogen dissemination. In total, 650 sandflies were captured between June and August 2015 using sticky paper traps in the governorate of Sidi Bouzid, a classical focus of L. major in the Central-West of Tunisia. Polymerase chain reaction-restriction fragment length polymorphism analysis of the internal transcribed spacer 1 and sequencing were used for Leishmania detection and identification. Ninety-seven unfed females were tested for the presence of Leishmania parasite DNA. Six Phlebotomus sergenti were found positive for L. tropica. This finding enhances the understanding of the cycle extension of L. tropica outside its original focus of Tataouine in the South-East of the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cutaneous%20leishmaniasis" title="cutaneous leishmaniasis">cutaneous leishmaniasis</a>, <a href="https://publications.waset.org/abstracts/search?q=Leishmania%20tropica" title=" Leishmania tropica"> Leishmania tropica</a>, <a href="https://publications.waset.org/abstracts/search?q=sandflies" title=" sandflies"> sandflies</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/127947/infection-of-phlebotomus-sergenti-with-leishmania-tropica-in-a-classical-focus-of-leishmania-major-in-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127947.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">156</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">78</span> Novel Ultrasensitive Point of Care Device for Diagnosis of Human Schistosomiasis Mansoni</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Aly">Ibrahim Aly</a>, <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Elawamy"> Waleed Elawamy</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Taher"> Hanan Taher</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Matar"> Amira Matar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Schistosomiasis is infection with blood flukes of the genus Schistosoma, which are acquired trans-cutaneously by swimming or wading in contaminated freshwater.
