studies have attempted to describe the demand for primary care in a standardized and systematic way. The purpose of this study is to describe the main reasons for demand for care in primary health care, through a survey of the Ariana Governorate PHC and to identify their evolutionary trend compared to last 30 years, reported by studies of the same type. Materials and methods: This is a cross-sectional descriptive study which concerns the study of consultants in the first line of the governorate of Ariana and their use of care recorded during 2 days in the same week during the month of May 2016, in each of these PHC. The same data collection sheet was used in all CSBs. The coding of the information was done according to the International Classification of Primary Care (ICPC). The data was entered and analyzed by the EPI Info 7 software. Results: Our study found that the most common ICPC chapters are respiratory (42%) and digestive (13.2%). In 1996 were the respiratory (43.5%) and circulatory (7.8%). In 2000, we found also the respiratory (39,6%) and circulatory (10,9%). In 2002, respiratory (43%) and digestive (10.1%) motives were the most frequent. According to the ICPC, the pathologies in our study were acute angina (19%), acute bronchitis and bronchiolitis (8%). In 1996, it was tonsillitis ( 21.6%) and acute bronchitis (7.2%). For Ben Abdelaziz in 2000, tonsillitis (14.5%) follow by acute bronchitis (8.3%). In 2002, acute angina (15.7%), acute bronchitis and bronchiolitis (11.2%) were the most common. Conclusion: Acute angina and tonsillitis are the most common in all studies conducted in Tunisia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20angina" title="acute angina">acute angina</a>, <a href="https://publications.waset.org/abstracts/search?q=classification%20of%20primary%20care" title=" classification of primary care"> classification of primary care</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20health%20care" title=" primary health care"> primary health care</a>, <a href="https://publications.waset.org/abstracts/search?q=tonsillitis" title=" tonsillitis"> tonsillitis</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/83861/demand-for-care-in-primary-health-care-in-the-governorate-of-ariana-results-of-a-survey-in-ariana-primary-health-care-and-comparison-with-the-last-30-years" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83861.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">530</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">265</span> Enhanced Production of Nisin by Co-culture of Lactococcus Lactis Sub SP.

Nisin production through co-culture fermentation can be performed for increasing nisin quantities. Since lactate accumulation in the fermentation medium can prevent L. lactis growth and therefore reduce nisin production, the simultaneous culture of microorganisms can enhance L. lactis growth by a reduction in the amount of lactic acid. In this study, conducted coculture of L.lactis subsp. lactic and the yeast Yarrowia lipolytica. Both strains are cultured in a molasses-based medium that is mainly constructed of sucrose. Y. lipolytica is not able to use sucrose as a carbon source but is able to consume lactate and decrease lactic acid in the medium. So, Lactic acid consumption can increase pH value and stimulate L. lactis growth. The results showed the mixed culture increased L. lactis growth 6 times higher than that of pure culture and could enhance nisin activity by up to 40%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=co-culture%20fermentation" title="co-culture fermentation">co-culture fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=lactococcus%20lactis%20subsp%20lactis" title=" lactococcus lactis subsp lactis"> lactococcus lactis subsp lactis</a>, <a href="https://publications.waset.org/abstracts/search?q=yarrowia%20lipolytica" title=" yarrowia lipolytica"> yarrowia lipolytica</a>, <a href="https://publications.waset.org/abstracts/search?q=nisin" title=" nisin"> nisin</a> </p> <a href="https://publications.waset.org/abstracts/149292/enhanced-production-of-nisin-by-co-culture-of-lactococcus-lactis-sub-sp-lactis-and-yarrowia-lipolytica-in-molasses-based-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149292.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">109</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">264</span> Critical Analysis of Media Discourse and the Politics of Self-Censorship in Afghanistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Wahab%20Rahimi">Abdul Wahab Rahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research examines the role of discursive strategies in the politics of self-censorship in Afghanistan, where political pressure, press freedom, and independent media work together, and language plays a vital role in implementing these strategies. Critical Discourse Analysis was conducted to describe the connection between language usage and the exercise of power by analyzing news stories related to women’s rights. This research focuses on 11 months of chronologically collected data from two mainstream television channels in Afghanistan: Tolo News and Ariana News. The findings show that Tolo News sustains and justifies juxtaposition and political critics’ discursive strategies to address women’s rights issues, criticize government policies, and deal with political pressure. At the same time, Ariana News follows the factual narrative strategy, practices self-censorship, and skips or partially focuses on the objective reporting of sensitive issues. The research concludes that the domestic media in Afghanistan follows the media policy of the Islamic Emirate of Afghanistan by covering sensitive issues and marginalizing women's rights issues in the media discourse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discursive%20strategies" title="discursive strategies">discursive strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=Taliban" title=" Taliban"> Taliban</a>, <a href="https://publications.waset.org/abstracts/search?q=TV%20Channel" title=" TV Channel"> TV Channel</a>, <a href="https://publications.waset.org/abstracts/search?q=news%20stories" title=" news stories"> news stories</a>, <a href="https://publications.waset.org/abstracts/search?q=self-censorship" title=" self-censorship"> self-censorship</a>, <a href="https://publications.waset.org/abstracts/search?q=women%27s%20rights." title=" women's rights."> women's rights.</a> </p> <a href="https://publications.waset.org/abstracts/193581/critical-analysis-of-media-discourse-and-the-politics-of-self-censorship-in-afghanistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193581.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">13</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">263</span> Flow Duration Curve Method to Evaluate Environmental Flow: Case Study of Gharasou River, Ardabil, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Fuladipanah">Mehdi Fuladipanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jorabloo"> Mehdi Jorabloo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water flow management is one of the most important parts of river engineering.

In the present study, genetic diversity and relationships among 20 collected purslane accessions were evaluated using ISSR markers. The genotyping data were used to understand the relationships among the collected accessions and identify genetically diverse purslane accessions. The 25 primers gave a total of 92 bands, of which 62 were polymorphic (67.4%). The genetic diversity as estimated by Shannon’s information index was 0.55, revealing a quite high level of genetic diversity in the germplasm. The average number of an observed allele, effective allele, polymorphic information content (PIC) and Nei’s index were 2, 1.65, 0.37 and 0.37, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Portulaca%20oleracea%20L." title="Portulaca oleracea L.">Portulaca oleracea L.</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=ISSR" title=" ISSR"> ISSR</a>, <a href="https://publications.waset.org/abstracts/search?q=germplasm" title=" germplasm"> germplasm</a> </p> <a href="https://publications.waset.org/abstracts/63005/assessment-of-genetic-diversity-of-iranian-purslane-portulaca-oleracea-l-accessions-using-issr-makers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63005.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">451</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">260</span> The Toxicity Effects of HICIDE VD-9 on the Mortality of Lucilia cuprina under Laboratory Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Shahmoradi%20Moghadam">Mehdi Shahmoradi Moghadam</a>, <a href="https://publications.waset.org/abstracts/search?q=Saba%20Kavian"> Saba Kavian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Zabihzadeh"> Mehdi Zabihzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Mohammad%20Alborzi"> Amir Mohammad Alborzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Sadeghi"> Reza Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cypermethrin is one of the most widely used synthetic insecticides to control pests in veterinary, industrial and agricultural environments. In the present study, the mortalities of Lucilia Cuprina as the key pest of meat were studied after being exposed to HICIDE VD-9 (a ready-to-use disinfectant/insecticide containing cypermethrin, polyhexanide and quaternary ammonium compounds produced by Dana pharmed lotus Co., Iran) within 15 minutes. The experimental results showed that moralities percentage of egg, larvae and adults of Lucilia Cuprina were 48%, 81% and 70%, respectively. Based on the obtained results, it can be predicted that in addition to controlling the insect pests of blow flies, HICIDE VD-9, as a cost-effective and environmentally friendly disinfectant/insecticide, can be effective against other insects, e.g., biting flies, fleas, midges, mosquitoes and ticks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cypermethrin" title="cypermethrin">cypermethrin</a>, <a href="https://publications.waset.org/abstracts/search?q=HICIDE%20VD-9" title=" HICIDE VD-9"> HICIDE VD-9</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucilia%20cuprina" title=" Lucilia cuprina"> Lucilia cuprina</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a> </p> <a href="https://publications.waset.org/abstracts/176093/the-toxicity-effects-of-hicide-vd-9-on-the-mortality-of-lucilia-cuprina-under-laboratory-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176093.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">110</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">259</span> Hydrological Method to Evaluate Environmental Flow: Case Study of Gharasou River, Ardabil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Fuladipanah">Mehdi Fuladipanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jorabloo"> Mehdi Jorabloo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water flow management is one of the most important parts of river engineering.

To maintain river at an acceptable ecological condition, minimum daily discharge of index Q95 is 0.7 m^3.s^-1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gharasou%20River" title="Gharasou River">Gharasou River</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20flow%20management" title=" water flow management"> water flow management</a>, <a href="https://publications.waset.org/abstracts/search?q=non-uniformity%20distribution" title=" non-uniformity distribution"> non-uniformity distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20flow%20requirement" title=" ecosystem flow requirement"> ecosystem flow requirement</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20alteration" title=" hydraulic alteration"> hydraulic alteration</a> </p> <a href="https://publications.waset.org/abstracts/22677/hydrological-method-to-evaluate-environmental-flow-case-study-of-gharasou-river-ardabil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22677.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">335</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">258</span> Internal DC Short-Circuit Fault Analysis and Protection for VSI of Wind Power Generation Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Radmehr">Mehdi Radmehr</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Hamed%20Mashhadzadeh"> Amir Hamed Mashhadzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jafari"> Mehdi Jafari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional HVDC systems are tough to DC short circuits as they are current regulated with a large reactance connected in series with cables. Multi-terminal DC wind farm topologies are attracting increasing research attempt. With AC/DC converters on the generator side, this topology can be developed into a multi-terminal DC network for wind power collection, which is especially suitable for large-scale offshore wind farms. For wind farms, the topology uses high-voltage direct-current transmission based on voltage-source converters (VSC-HVDC). Therefore, they do not suffer from over currents due to DC cable faults and there is no over current to react to. In this study, the multi-terminal DC wind farm topology is introduced. Then, possible internal DC faults are analyzed according to type and characteristic. Fault over current expressions are given in detail. Under this characteristic analysis, fault detection and detailed protection methods are proposed. Theoretical analysis and PSCAD/EMTDC simulations are provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC%20short%20circuits" title="DC short circuits">DC short circuits</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-terminal%20DC%20wind%20farm%20topologies" title=" multi-terminal DC wind farm topologies"> multi-terminal DC wind farm topologies</a>, <a href="https://publications.waset.org/abstracts/search?q=HVDC%20transmission%20based%20on%20VSC" title=" HVDC transmission based on VSC"> HVDC transmission based on VSC</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20analysis" title=" fault analysis"> fault analysis</a> </p> <a href="https://publications.waset.org/abstracts/10282/internal-dc-short-circuit-fault-analysis-and-protection-for-vsi-of-wind-power-generation-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10282.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">421</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">257</span> Pollution Assessment and Potential Ecological Risk of Some Traces Metals in the Surface Sediments of the Gulf of Tunis, North Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ha%C3%AFfa%20Ben%20Mna">Haïfa Ben Mna</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayed%20Added"> Ayed Added</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To evaluate the trace metals contamination status in the Gulf of Tunis, forty one sediment samples were analyzed using different approaches. According to certain contamination and ecological risk indices (Contamination Factor, Geoaccumulation index and Ecological risk index), Hg has the highest contamination level while pollution by Ni, Pb, Cd and Cr was absent. The highest concentrations of trace metals were found in sediments collected from the offshore and coastal areas located opposite the main exchange points with the gulf particularly, the Mejerda and Meliane Rivers, the Khalij Channel, Ghar El Melh and El Malah lagoons, Tunis Lake and Sebkhat Ariana. However, further ecological indices (Potential ecological risk index, Toxic unit and Mean effect-range median quotient) and comparison with sediment quality guidelines suggest that in addition to Mercury, Cr, Pb and Ni concentrations are detrimental to biota in both the offshore and areas near to the exchange points with the gulf. Moreover, in these areas the results from sequential extraction and individual contamination factor calculation pointed to the mobility and bioavailability of Cr, Pb and Ni. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sediment" title="sediment">sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=trace%20metals" title=" trace metals"> trace metals</a>, <a href="https://publications.waset.org/abstracts/search?q=contamination%20assessment" title=" contamination assessment"> contamination assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20risk" title=" ecological risk"> ecological risk</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunis%20gulf" title=" Tunis gulf"> Tunis gulf</a> </p> <a href="https://publications.waset.org/abstracts/164916/pollution-assessment-and-potential-ecological-risk-of-some-traces-metals-in-the-surface-sediments-of-the-gulf-of-tunis-north-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164916.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">256</span> Numerical Study of Partial Penetration of PVDs In Soft Clay Soils Treatment Along With Surcharge Preloading (Bangkok Airport Case Study)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mehdi%20Pardsouie">Mohammad Mehdi Pardsouie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Mokhberi"> Mehdi Mokhberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Ali%20Zomorodian"> Seyed Mohammad Ali Zomorodian</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Alireza%20Nasehi"> Seyed Alireza Nasehi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the challenging parts of every project, including prefabricated vertical drains (PVDs), is the determination of the depth of installation and its configuration. In this paper, Geostudio 2018 was used for modeling and verification of the full-scale test embankments (TS1, TS2, and TS3), which were constructed to study the effectiveness of PVDs for accelerating the consolidation and dissipation of the excess pore-pressures resulting from fill placement at Bangkok airport. Different depths and scenarios were modeled and the results were compared and analyzed. Since the ultimate goal is attaining pre-determined settlement, the settlement curve under soil embankment was used for the investigation of the results. It was shown that nearly in all cases, the same results and efficiency might be obtained by partial depth installation of PVDs instead of complete full constant length installation. However, it should be mentioned that because of distinct soil characteristics of clay soils and layers properties of any project, further investigation of full-scale test embankments and modeling is needed prior to finalizing the ultimate design by competent geotechnical consultants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20penetration" title="partial penetration">partial penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=surcharge%20preloading" title=" surcharge preloading"> surcharge preloading</a>, <a href="https://publications.waset.org/abstracts/search?q=excess%20pore%20water%20pressure" title=" excess pore water pressure"> excess pore water pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok%20test%20embankments" title=" Bangkok test embankments"> Bangkok test embankments</a> </p> <a href="https://publications.waset.org/abstracts/143189/numerical-study-of-partial-penetration-of-pvds-in-soft-clay-soils-treatment-along-with-surcharge-preloading-bangkok-airport-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143189.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">207</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">255</span> Integrating GIS and Analytical Hierarchy Process-Multicriteria Decision Analysis for Identification of Suitable Areas for Artificial Recharge with Reclaimed Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoudi%20Marwa">Mahmoudi Marwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahim%20Nadhem"> Bahim Nadhem</a>, <a href="https://publications.waset.org/abstracts/search?q=Aydi%20Abdelwaheb"> Aydi Abdelwaheb</a>, <a href="https://publications.waset.org/abstracts/search?q=Issaoui%20Wissal"> Issaoui Wissal</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Najet"> S.

On regional characteristics, bibliography and available data on artificial recharge, 13 constraints and 5 factors were hierarchically structured for the adequacy of an artificial recharge. The factors are subdivided into two main groups: environmental factors and economic factors. The adopted methodology allows a preliminary assessment of a recharge site, the weighted linear combination (WLC) and the analytical hierarchy process (AHP) in a GIS. The standardization of the criteria is carried out by the application of the different membership functions. The form and control points of the latter are defined by the consultation of the experts. The weighting of the selected criteria is allocated according to relative importance using the AHP methodology. The weighted linear combination (WLC) integrates the different criteria and factors to delineate the most suitable areas for artificial recharge site selection by treated wastewater. The results of this study showed three potential candidate sites that appear when environmental factors are more important than economic factors. These sites are ranked in descending order using the ELECTRE III method. Nevertheless, decision making for the selection of an artificial recharge site will depend on the decision makers in force. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20recharge%20site" title="artificial recharge site">artificial recharge site</a>, <a href="https://publications.waset.org/abstracts/search?q=treated%20wastewater" title=" treated wastewater"> treated wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchy%20process" title=" analytical hierarchy process"> analytical hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=ELECTRE%20III" title=" ELECTRE III "> ELECTRE III </a> </p> <a href="https://publications.waset.org/abstracts/105235/integrating-gis-and-analytical-hierarchy-process-multicriteria-decision-analysis-for-identification-of-suitable-areas-for-artificial-recharge-with-reclaimed-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105235.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">166</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">254</span> International Classification of Primary Care as a Reference for Coding the Demand for Care in Primary Health Care</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Souhir%20Chelly">Souhir Chelly</a>, <a href="https://publications.waset.org/abstracts/search?q=Chahida%20Harizi"> Chahida Harizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Hechaichi"> Aicha Hechaichi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sihem%20Aissaoui"> Sihem Aissaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Ben%20Ayed"> Leila Ben Ayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Bergaoui"> Maha Bergaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Kouni%20Chahed"> Mohamed Kouni Chahed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The International Classification of Primary Care (ICPC) is part of the morbidity classification system. It had 17 chapters, and each is coded by an alphanumeric code: the letter corresponds to the chapter, the number to a paragraph in the chapter. The objective of this study is to show the utility of this classification in the coding of the reasons for demand for care in Primary health care (PHC), its advantages and limits. Methods: This is a cross-sectional descriptive study conducted in 4 PHC in Ariana district. Data on the demand for care during 2 days in the same week were collected. The coding of the information was done according to the CISP. The data was entered and analyzed by the EPI Info 7 software. Results: A total of 523 demands for care were investigated. The patients who came for the consultation are predominantly female (62.72%). Most of the consultants are young with an average age of 35 ± 26 years. In the ICPC, there are 7 rubrics: 'infections' is the most common reason with 49.9%, 'other diagnoses' with 40.2%, 'symptoms and complaints' with 5.5%, 'trauma' with 2.1%, 'procedures' with 2.1% and 'neoplasm' with 0.3%. The main advantage of the ICPC is the fact of being a standardized tool. It is very suitable for classification of the reasons for demand for care in PHC according to their specificity, capacity to be used in a computerized medical file of the PHC. Its current limitations are related to the difficulty of classification of some reasons for demand for care. Conclusion: The ICPC has been developed to provide healthcare with a coding reference that takes into account their specificity. The CIM is in its 10th revision; it would gain from revision to revision to be more efficient to be generalized and used by the teams of PHC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=international%20classification%20of%20primary%20care" title="international classification of primary care">international classification of primary care</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20file" title=" medical file"> medical file</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20health%20care" title=" primary health care"> primary health care</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/85569/international-classification-of-primary-care-as-a-reference-for-coding-the-demand-for-care-in-primary-health-care" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85569.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">267</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">253</span> Sea Protection: Using Marine Algae as a Natural Method of Absorbing Dye Textile Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ariana%20Kilic">Ariana Kilic</a>, <a href="https://publications.waset.org/abstracts/search?q=Serena%20Arapyan"> Serena Arapyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water pollution is a serious concern in all seas around the world and one major cause of it is dye textile wastes mixing with seawater. This common incident alters aquatic life, putting organisms’ lives in danger and deteriorating the water's nature. There is a significant need for a natural approach to reduce the amount of dye textile waste in seawater and ensure marine organisms' safety. Consequently, using marine algae is a viable solution since it can eliminate the excess waste by absorbing the dye. Also, marine algae are non-vascular that absorb water and nutrients, meaning that having them as absorbers is a natural process and no inorganic matters will be added to the seawater that could result in further pollution. To test the efficiency of this approach, the optical absorbance of the seawater samples was measured before and after the addition of marine algae by utilizing colorimetry. A colorimeter is used to find the concentration of a chemical compound in a solution by measuring the absorbance of the compound at a specific wavelength. Samples of seawater that have equal amounts of water were used and textile dye was added as the constant variables. The initial and final absorbances, the dependent variable, of the water were measured before and after the addition of marine algae, the independent variable, and observed. The lower the absorbance showed us that there is lower dye concentration and therefore, the marine algae had done its job by using and absorbing the dye. The same experiment was repeated with same amount of water but with different concentrations of dye in order to determine the maximum concentration of dye the marine algae can completely absorb. The diminished concentration of dye demonstrated that pollution caused by factories’ dye wastes could be prevented with the natural method of marine algae. The involvement of marine algae is an optimal strategy for having an organic solution to absorbing the dye wastes in seas and obstructing water pollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20pollution" title="water pollution">water pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20textile%20waste" title=" dye textile waste"> dye textile waste</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20algae" title=" marine algae"> marine algae</a>, <a href="https://publications.waset.org/abstracts/search?q=absorbance" title=" absorbance"> absorbance</a>, <a href="https://publications.waset.org/abstracts/search?q=colorimetry" title=" colorimetry"> colorimetry</a> </p> <a href="https://publications.waset.org/abstracts/189308/sea-protection-using-marine-algae-as-a-natural-method-of-absorbing-dye-textile-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189308.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">20</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">252</span> Implications of Oxidative Stress for Monoterpenoid Oxindole Alkaloid Production in Uncaria tomentosa Cultures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20C.%20Ramos%20Valdivia">Ana C.

A limited number of species of plants like Uncaria tomentosa (cat claw) typical of the Amazon region produce monoterpenoid oxindole alkaloids (MOA) such as isopteropodine, mitraphylline, rhynchophylline and its isomers. Moreover, in cultivated roots, the glucoindole alkaloid 3α-dihydrocadambine (DHC) is also accumulated. Several studies have demonstrated that MAO has antioxidant properties and possess important pharmacological activities such as antitumor and immunostimulant while DHC, has hypotensive and hypolipidemic effects. In order the study the regulatory concerns operating in MAO production, the links between oxidative stress and antioxidant alkaloid production in U. tomentosa root cultures were examined. Different amount of hydrogen peroxide between 0.2 -1.0 mM was added to 12 days old roots cultures showing that, this substance had a differential effect on the production of DHC and MOA whereas the viability remained in 80% after six days. Addition of 0.2 mM hydrogen peroxide increased approximately 65% MAO and DHC production (0,540 ± 0.018 and 0.618 ± 0.029 mg per g dry weight, respectively) relative to the control. On contrast, after the addition of 0.6 mM and 1 mM hydrogen peroxide, DHC accumulation into the roots gradually decreased to 53% and 93% respectively, without changes in MAO concentration, which was in relation to a twice increase of the intracellular hydrogen peroxide content. On the other hand, concentrations of DHC (0.1, 0.5 and 1.0 mM in methanol) demonstrated free-radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The calculated IC50 for all tested concentrations was 0.180 mg per ml (0.33 mM) while the calculated TE50 was 276 minutes. Our results suggest that U. tomentosa root cultures both MAO and DHC have antioxidant capacities and respond to oxidative stress with a stimulation of their production; however, in presence of a higher concentration of ROS into the roots, DHC could be oxidized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monoterpenoid%20indole%20alkaloid" title="monoterpenoid indole alkaloid">monoterpenoid indole alkaloid</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20cultures" title=" root cultures"> root cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=uncaria%20tomentosa" title=" uncaria tomentosa"> uncaria tomentosa</a> </p> <a href="https://publications.waset.org/abstracts/71305/implications-of-oxidative-stress-for-monoterpenoid-oxindole-alkaloid-production-in-uncaria-tomentosa-cultures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71305.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">182</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">251</span> RANS Simulation of the LNG Ship Squat in Shallow Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Nakisa">Mehdi Nakisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Adi%20Maimun"> Adi Maimun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20M.%20Ahmed"> Yasser M.

This system is a useful tool for Digital Signal Processing (DSP) since it can support parallel, carry-free, high-speed and low power arithmetic. One of the drawbacks of Residue Number System is the fractional numbers, that is, the corresponding circuit is very hard to realize in conventional CMOS technology. In this paper, we propose a method in which the numbers of transistors are significantly reduced. The related delay is extremely diminished, in the first glance we use this method to solve concerning problem of one decimal functional number some how this proposition can be extended to generalize the idea.

This shape was descending in cash flow certainly and uncertainly but it is ascending in medial position. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dividends" title="dividends">dividends</a>, <a href="https://publications.waset.org/abstracts/search?q=investment" title=" investment"> investment</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20relationship" title=" nonlinear relationship"> nonlinear relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty%20of%20cash%20flow" title=" uncertainty of cash flow"> uncertainty of cash flow</a> </p> <a href="https://publications.waset.org/abstracts/45030/the-relationship-between-investment-and-dividend-in-a-condition-of-cash-flow-uncertainly-evidence-from-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45030.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">329</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">237</span> Investigation the Effect of Nano-Alumina Particles on Physical Adsorption Property of Acrylic Fiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Ketabchi">Mehdi Ketabchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shamsollah%20Alijanlou"> Shamsollah Alijanlou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The flue gas from fossil fuels combustion contains harmful pollutants dangerous for human health and the environment. One of the air pollution control methods to restrict the emission of these pollutants is based on using the nanoparticle in the adsorption process. In the present research gamma, Nano-alumina particle is added to Polyacrylonitrile (PAN) polymer through simple loading method and the adsorption capacity of the wet spun fiber is investigated. The results of exposure the fiber to the acid gasses including SO2, CO, NO2, NO and CO2 show the noticeable increase of gas adsorption capacity on fiber contains nanoparticle. The research has been conducted in Acrylic II Plant of Polyacryl Iran Corporation. <p class="card-text"><strong>Keywords:</strong> <a
