56.3% of its economic entities come from the commercial sector. Shopping centers are the new form of commerce that has emerged in the city since the 2000s. They are considered to be commercial and leisure poles and major generators of travel. However, shopping centers in the capital Algiers are poorly served by public transport, and their choice of location is mainly conditioned by the availability of land; accessibility by public transport does not appear to be an important criterion in the choice of their location. As a result, travel to and from these commercial centers is mainly by car, which breaks with the sustainability objectives of national transportation policy. Our study attempts to examine the impact of public transport accessibility of shopping centers on consumers' travel behaviour. The main objective of this research is to determine the link between the accessibility of these facilities, the use of private cars, and public transport modes. To this end, we analyze the choice of travel mode of consumers and the different factors that determine it by focusing on the influence of accessibility. The results showed a considerable influence of the accessibility on the travel behavior of the consumer in Algiers, so it is recommended to improve the accessibility of shopping centers by public transport in order to contribute to a modal shift. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessibility" title="accessibility">accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=shopping%20centers%20trips" title=" shopping centers trips"> shopping centers trips</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transportation" title=" public transportation"> public transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=Algiers" title=" Algiers"> Algiers</a> </p> <a href="https://publications.waset.org/abstracts/155833/shopping-centers-and-public-transport-study-of-the-shopping-centres-trips-of-algiers-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155833.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">99</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">48</span> The Carbon Footprint Model as a Plea for Cities towards Energy Transition: The Case of Algiers Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hachaichi%20Mohamed%20Nour%20El-Islem">Hachaichi Mohamed Nour El-Islem</a>, <a href="https://publications.waset.org/abstracts/search?q=Baouni%20Tahar"> Baouni Tahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environmental sustainability rather than a trans-disciplinary and a scientific issue, is the main problem that characterizes all modern cities nowadays. In developing countries, this concern is expressed in a plethora of critical urban ills: traffic congestion, air pollution, noise, urban decay, increase in energy consumption and CO<sub>2</sub> emissions which blemish cities’ landscape and might threaten citizens’ health and welfare. As in the same manner as developing world cities, the rapid growth of Algiers’ human population and increasing in city scale phenomena lead eventually to increase in daily trips, energy consumption and CO<sub>2</sub> emissions. In addition, the lack of proper and sustainable planning of the city’s infrastructure is one of the most relevant issues from which Algiers suffers. The aim of this contribution is to estimate the carbon deficit of the City of Algiers, Algeria, using the Ecological Footprint Model (carbon footprint). In order to achieve this goal, the amount of CO<sub>2</sub> from fuel combustion has been calculated and aggregated into five sectors (agriculture, industry, residential, tertiary and transportation); as well, Algiers’ biocapacity (CO<sub>2</sub> uptake land) has been calculated to determine the ecological overshoot. This study shows that Algiers’ transport system is not sustainable and is generating more than 50% of Algiers total carbon footprint which cannot be sequestered by the local forest land. The aim of this research is to show that the Carbon Footprint Assessment might be a relevant indicator to design sustainable strategies/policies striving to reduce CO<sub>2</sub> by setting in motion the energy consumption in the transportation sector and reducing the use of fossil fuels as the main energy input. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocapacity" title="biocapacity">biocapacity</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20footprint" title=" carbon footprint"> carbon footprint</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20footprint%20assessment" title=" ecological footprint assessment"> ecological footprint assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a> </p> <a href="https://publications.waset.org/abstracts/104000/the-carbon-footprint-model-as-a-plea-for-cities-towards-energy-transition-the-case-of-algiers-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104000.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">147</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">47</span> Environmental Impacts on Urban Agriculture in Algiers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Bouzekri">Sara Bouzekri</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Madani"> Said Madani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In many Mediterranean cities such as Algiers, the human activity, the strong mobility the urban sprawl, the air pollution, the problems of waste management, the wasting of the resources and the degradation of the environment weaken in an unquestionable way the farming. The question of sustainable action vis-a-vis these threats arises then in order to maintain a level of desired local development. The methodology is based on a multi-criteria method based on the AFOM diagnosis, which classifies agricultural strength indicators and those of threat, according to an analytical approach. In a sustainable development perspective, it will be appropriate to link the threat factors of the case study with the factors of climate change to see their impact on the future of agriculture. This will be accompanied by a SWOT analysis, which crosses the most significant criteria to arrive at the necessary recommendations based on future projects for urban agriculture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algiers" title="Algiers">Algiers</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20agriculture" title=" urban agriculture"> urban agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=threat%20factors" title=" threat factors"> threat factors</a> </p> <a href="https://publications.waset.org/abstracts/61519/environmental-impacts-on-urban-agriculture-in-algiers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61519.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Evaluating the Impact of Urbanization on Local Biodiversity and Ecosystem Functioning: A Case Study of Algiers, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akram%20Sadouki">Akram Sadouki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urbanization is one of the most significant drivers of biodiversity loss and ecosystem degradation. This study aims to evaluate the impact of urban expansion on local biodiversity and ecosystem functioning in Algiers, Algeria. Using a combination of field surveys, remote sensing data, and GIS analysis, we quantified changes in land use and land cover over the past three decades. Our results indicate a substantial reduction in green spaces and natural habitats, leading to a decline in native species diversity and abundance. Furthermore, we observed alterations in ecosystem services, including reduced air and water quality, increased urban heat island effects, and diminished carbon sequestration capabilities. This paper highlights the urgent need for sustainable urban planning and conservation strategies to mitigate the adverse effects of urbanization on biodiversity. We propose several policy recommendations, such as the creation of urban green belts, restoration of degraded areas, and incorporation of biodiversity considerations into city planning processes. By adopting these measures, Algiers can enhance its resilience to environmental changes and ensure the well-being of its inhabitants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20functioning" title=" ecosystem functioning"> ecosystem functioning</a>, <a href="https://publications.waset.org/abstracts/search?q=Algiers" title=" Algiers"> Algiers</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanization" title=" urbanization"> urbanization</a> </p> <a href="https://publications.waset.org/abstracts/188730/evaluating-the-impact-of-urbanization-on-local-biodiversity-and-ecosystem-functioning-a-case-study-of-algiers-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188730.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">37</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Evaluation of Salt Content in Bread and the Amount Intake by Hypertensive Patients in the Algiers Region</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.lanasri">S.lanasri</a>, <a href="https://publications.waset.org/abstracts/search?q=A.Boudjerrane"> A.Boudjerrane</a>, <a href="https://publications.waset.org/abstracts/search?q=R.Belgherbi"> R.Belgherbi</a>, <a href="https://publications.waset.org/abstracts/search?q=O.Hadjoudj"> O.Hadjoudj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Bread is the most popular food in Algeria. The aim of this study was to examine the consumption of salt from bread by hypertensive patients. Materials and methods: sixty breads were collected from different artisans Algiers bakeries, each sample was mixed in harm distilled water until homogeneous and filtered. Analysis of the salt content was carried out according to the Mohr method titration. We calculated the amount of salt in bread consumed by 100 hypertensive patients using a questionnaire about the average amount of bread per day. Results: The salt content values from bread were 3.4g ± 0.37 NaCl / 100g.The average amount of salt consumed per day by patients from only bread was 3.82 g ± 3.8 with a maximum of 17 g per day. Only 38.18% of patients consume bread without salt even then 95% knew that excess salt intake can complicate hypertension. Conclusion: This study showed that bread is a major contributor to salt intake by Algerian hypertensive patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salt" title="salt">salt</a>, <a href="https://publications.waset.org/abstracts/search?q=bread" title=" bread"> bread</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertensive%20patients" title=" hypertensive patients"> hypertensive patients</a>, <a href="https://publications.waset.org/abstracts/search?q=Algiers" title=" Algiers"> Algiers</a> </p> <a href="https://publications.waset.org/abstracts/117913/evaluation-of-salt-content-in-bread-and-the-amount-intake-by-hypertensive-patients-in-the-algiers-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117913.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">151</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">44</span> A Book Review of Inside the Battle of Algiers, by Zohra Drif: A Thematic Analysis on Women’s Agency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Zekri">W.

This book review aims to evaluate the concept of women’s agency through education and language learning, and its impact on empowering women’s desires. Close-reading method and thematic analysis are used to explore the text. The analysis identified themes that refine the meaning of agency which are social and cultural supports, education, and language proficiency. These themes aim to contribute to the representation in <em>Inside the Battle of Algiers </em>of a woman guerrilla who engaged herself to perform national acts of resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agency" title="agency">agency</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a> </p> <a href="https://publications.waset.org/abstracts/95211/a-book-review-of-inside-the-battle-of-algiers-by-zohra-drif-a-thematic-analysis-on-womens-agency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95211.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">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Cable Transport for a Smart City: Between Challenges and Opportunities, Case of the City of Algiers, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ihaddadene%20Thanina">Ihaddadene Thanina</a>, <a href="https://publications.waset.org/abstracts/search?q=Haraoubia%20Imane"> Haraoubia Imane</a>, <a href="https://publications.waset.org/abstracts/search?q=Baouni%20Tahar"> Baouni Tahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urban mobility is one of the first challenges of cities; it is becoming more and more problematic because it is perceived as the cause of many dysfunctions; it is not only to facilitate accessibility but also to ensure vast benefits. For this reason, several cities in the world have thought about alternatives to smart mobility and sustainable transport. Today, the sustainable city has many cards at its disposal, and a new mode is entering the urban scene: aerial cable transport; it has imposed itself as an effective mode of public transport and a real solution for the future. This electric mobility brings a new dimension, not only to collective daily travel but also to the urban space. It has an excellent capacity to redevelop the public space; it is a catalyst that allows one to appreciate the view from the sky and to discover different large-scale projects that bring an important attractiveness to the city. With regard to the cities in the world which use these systems of transport: Algeria does not escape this reality; it is the country which has the greatest number of devices of urban transport by cable in the world, with installations in many cities such as Tlemcen, Constantine, Blida, Oran, Tizi-Ouzou, Annaba, Skikda. The following study explores the role of cable transport in the transformation of the city of Algiers into a smart city. The methodology used in this work is based on the development of a set of indicators using a questionnaire survey. The main objective of this work is to shed light on cable transport as a key issue in designing the sustainable city of tomorrow, to evaluate its role in the city of Algiers, and its ability to integrate into the urban transport network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algiers" title="Algiers">Algiers</a>, <a href="https://publications.waset.org/abstracts/search?q=cable%20transport" title=" cable transport"> cable transport</a>, <a href="https://publications.waset.org/abstracts/search?q=indicators" title=" indicators"> indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a> </p> <a href="https://publications.waset.org/abstracts/155929/cable-transport-for-a-smart-city-between-challenges-and-opportunities-case-of-the-city-of-algiers-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155929.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">113</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">42</span> Effect of the Fluid Temperature on the Crude Oil Fouling in the Heat Exchangers of Algiers Refinery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rima%20Harche">Rima Harche</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkader%20Mouheb"> Abdelkader Mouheb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Algiers refinery as all the other refineries always suffers from the problem of stopping of the tubes of heat exchanger.

The objectives behind such strategic interventions are on the one hand, to carry out an incremental approach aiming at eradicating precarious housing and on the other hand, to diversify alternative housing options for families requiring better living spaces. It is precisely for these same purposes that the Djenan el-Hassan and Carrières Jaubert estates, which are both located in Algiers, have undergone major urban transformations. These dwelling sites were built as part of the famous "Battle of Housing", which was launched by French colonial administration in the 1950s just before the independence of Algeria in 1962. Today, the Djenan el-Hassan estate is almost entirely demolished following the relocation of 171 families. The Carrières Jaubert estate, for its part, has seen two kinds of operations. The first has been shaped by a process of urban requalification and redevelopment, which allowed some of the residents to stay on site after the transformation of most housing cells into larger apartments. The second operation has required the relocation of over 300 families to entirely newly built dwellings. Such projects of urban renewal are supposed to create new opportunities, not only in terms of local urban development, but also in terms of social perspectives for those families who are involved, either directly or indirectly, in the process of relocation. In fact, the percentage of urban violence in Algiers has increased instead. Recent events in the newly built estates show that residents are repeatedly experiencing and even instigating episodes of brutality, hostility and aggression. The objective of this paper is to examine the causes that have engendered such rise in urban violence in newly built housing estates in Algiers. This paper aims to present the findings of a recent qualitative research and highlight the way that poorly designed neighbourhood, combined with a relocation process that leaves little room for community participation, create inevitably severe social tensions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=relocation" title="relocation">relocation</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20housing" title=" social housing"> social housing</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a>, <a href="https://publications.waset.org/abstracts/search?q=Algiers" title=" Algiers"> Algiers</a> </p> <a href="https://publications.waset.org/abstracts/24146/urban-renewal-social-housing-relocation-and-violence-in-algiers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24146.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">541</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Use of Statistical Correlations for the Estimation of Shear Wave Velocity from Standard Penetration Test-N-Values: Case Study of Algiers Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soumia%20Merat">Soumia Merat</a>, <a href="https://publications.waset.org/abstracts/search?q=Lynda%20Djerbal"> Lynda Djerbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramdane%20Bahar"> Ramdane Bahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Amin%20Benbouras"> Mohammed Amin Benbouras</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Along with shear wave, many soil parameters are associated with the standard penetration test (SPT) as a dynamic in situ experiment. Both SPT-N data and geophysical data do not often exist in the same area. Statistical analysis of correlation between these parameters is an alternate method to estimate Vₛ conveniently and without additional investigations or data acquisition. Shear wave velocity is a basic engineering tool required to define dynamic properties of soils. In many instances, engineers opt for empirical correlations between shear wave velocity (Vₛ) and reliable static field test data like standard penetration test (SPT) N value, CPT (Cone Penetration Test) values, etc., to estimate shear wave velocity or dynamic soil parameters. The relation between Vs and SPT- N values of Algiers area is predicted using the collected data, and it is also compared with the previously suggested formulas of Vₛ determination by measuring Root Mean Square Error (RMSE) of each model. Algiers area is situated in high seismic zone (Zone III [RPA 2003: réglement parasismique algerien]), therefore the study is important for this region. The principal aim of this paper is to compare the field measurements of Down-hole test and the empirical models to show which one of these proposed formulas are applicable to predict and deduce shear wave velocity values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=empirical%20models" title="empirical models">empirical models</a>, <a href="https://publications.waset.org/abstracts/search?q=RMSE" title=" RMSE"> RMSE</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wave%20velocity" title=" shear wave velocity"> shear wave velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20penetration%20test" title=" standard penetration test"> standard penetration test</a> </p> <a href="https://publications.waset.org/abstracts/77386/use-of-statistical-correlations-for-the-estimation-of-shear-wave-velocity-from-standard-penetration-test-n-values-case-study-of-algiers-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77386.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">338</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">39</span> Chemical Risk Posed by Hospital Liquid Effluents Example CHU Beni Messous Algiers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laref%20Nabil">Laref Nabil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ecology is at the center of many debates and international regulations.

They were built in the aim to spend hot days of the year. Among these later, the residences of AbdelTif and the gardens of the dey (which exist always), benefit from important criteria which increase interior comfort. Their know-how is today in trend and can give us several considerations to the architectural design and to the landscape architecture. Their particularity is seen in the built-garden interactions and the design solutions. These later let the user live with vegetation, sky and water through maximum of places in the constructions. On the basis on an aesthetic-tectonic approach, which make in evidence the architectural criteria of the two quoted cases studies (the AbdelTif residence and the gardens of the dey), we will explain in the proposed paper, some important characteristics and design solutions, which contribute strongly to the concretisation and the materialisation of a landscape architecture, and which can be used in all the Mediterranean area. The proposed aesthetic-tectonic approach is based on the fusion between interior and exterior, in the aim to distinguish syntactic criteria. The syntactic criteria correspond to: The composition and the articulation between interior and exterior spaces, the employed materials in the quoted spaces, the manifestation processes. The major finding of this study is the identification of paradigmatic processes related to the architectural design. These later reveal more figurative (direct) than expressive (no direct) way of design and creativeness. While the figurative way benefits from a high level of manifestation, the expressive one benefits from more composed and articulated materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aesthetic%2Ftectonic%20approach" title="aesthetic/tectonic approach">aesthetic/tectonic approach</a>, <a href="https://publications.waset.org/abstracts/search?q=Algiers%20context" title=" Algiers context"> Algiers context</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=landscape%20architecture" title=" landscape architecture"> landscape architecture</a> </p> <a href="https://publications.waset.org/abstracts/32707/design-and-landscape-architecture-in-the-vernacular-housing-of-algiers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32707.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">405</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Treatment of Leaden Sludge of Algiers Refinery by Electrooxidation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Ighilahriz">K.

They are toxic and considered carcinogenic and dangerous even when they exist in trace amounts. At Algiers refinery, production, transportation, and refining of crude oil generate considerable waste in storage tanks; these residues result from the gravitational settling. The composition of these residues is essentially a mixture of hydrocarbon and lead. We propose in this work the application of electrooxidation treatment for the leachate of the leaden sludge. The effect of pH, current density and the electrolysis time were studied, the effectiveness of the processes is evaluated by measuring the chemical oxygen demand (COD). The dissolution is the best way to mobilize pollutants from leaden mud, so we conducted leaching before starting the electrochemical treatment. The process was carried out in batch mode using graphite anode and a stainless steel cathode. The results clearly demonstrate the compatibility of the technique used with the type of pollution studied. In fact, it allowed COD removal about 80%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrooxidation" title="electrooxidation">electrooxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=leaching" title=" leaching"> leaching</a>, <a href="https://publications.waset.org/abstracts/search?q=leaden%20sludge" title=" leaden sludge"> leaden sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20industry" title=" oil industry"> oil industry</a> </p> <a href="https://publications.waset.org/abstracts/35672/treatment-of-leaden-sludge-of-algiers-refinery-by-electrooxidation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35672.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">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Pathology of the Partridge Gambra Alectoris barbara in a Semi-Captive Breeding in the Algiers Sahel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Saadi-Idouhar">H.

Game birds are of interest because they play an important role for hunting federations and for the economy of a country. The breeding of indigenous breeds is necessary because it is of great economic interest. However, gambra breeding in the hunting centre of Zeralda (northern west of Algiers) is not easy, several diseases affecting Perdreaux and reproducing adults have been noted. Most of the diseases observed are parasitic in origin. This study is conducted during the 2010 breeding season. It is based on the autopsy of cadavers collected at the hunting centre and parasitic coprology. Indeed, the flotation enrichment method has identified several parasites such as Eimeria spp., Capillaria spp., and Ascaridia spp. Autopsied corpses show the importance of two major diseases, syngamosis caused to Syngamus trachea and histomonosis caused to Histomonas meleagridis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partridge" title="partridge">partridge</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock" title=" livestock"> livestock</a>, <a href="https://publications.waset.org/abstracts/search?q=eggs" title=" eggs"> eggs</a>, <a href="https://publications.waset.org/abstracts/search?q=affections%20pathology" title=" affections pathology"> affections pathology</a> </p> <a href="https://publications.waset.org/abstracts/101106/pathology-of-the-partridge-gambra-alectoris-barbara-in-a-semi-captive-breeding-in-the-algiers-sahel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101106.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">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Nonlinear Analysis of a Building Surmounted by a RC Water Tank under Hydrodynamic Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hocine%20Hammoum">Hocine Hammoum</a>, <a href="https://publications.waset.org/abstracts/search?q=Karima%20Bouzelha"> Karima Bouzelha</a>, <a href="https://publications.waset.org/abstracts/search?q=Lounis%20Ziani"> Lounis Ziani</a>, <a href="https://publications.waset.org/abstracts/search?q=Lounis%20Hamitouche"> Lounis Hamitouche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we study a complex structure which is an apartment building surmounted by a reinforced concrete water tank.

The aim of this paper is to describe the results of experimental as well as theoretical analysis of landslides. In order to understand the process which caused this slope instabilities, the results of geotechnical investigation carried out by the laboratory of construction (LNHC) laboratory in the area of Dounia park were analyzed, including particle size distribution, Atterberg limits, shear strength, odometer and pressuremeter tests. The study shows that the soils exhibited a high capacity to swelling according to index plasticity and clay content. Highs limit liquidity (LL) (53.45%) means that the soils are susceptible to landslides. The stability analysis carried out using finite element method, shows that the slope is stable (Fs > 1) in dry condition and in static state. Despite this results, the stable site could be described as only conditionally stable because slope failure can occur under combined effect of different factors. In fact the safety factor obtained by applying load when the phreatic surface is at ground, less than 1.5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=index%20properties" title="index properties">index properties</a>, <a href="https://publications.waset.org/abstracts/search?q=landslides" title=" landslides"> landslides</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20factor" title=" safety factor"> safety factor</a>, <a href="https://publications.waset.org/abstracts/search?q=slope%20stability" title=" slope stability"> slope stability</a> </p> <a href="https://publications.waset.org/abstracts/73166/geotechnical-characterization-of-landslide-in-dounia-park-algiers-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73166.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">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Molecular Survey and Genetic Diversity of Bartonella henselae Strains Infecting Stray Cats from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naouelle%20Azzag">Naouelle Azzag</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Haddad"> Nadia Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Durand"> Benoit Durand</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Petit"> Elisabeth Petit</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ammouche"> Ali Ammouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Chomel"> Bruno Chomel</a>, <a href="https://publications.waset.org/abstracts/search?q=Henri%20J.%20Boulouis"> Henri J.

In this research, we report the results of a cross sectional study of Bartonella henselae bacteremia in stray cats from Algiers. Whole blood of 227 stray cats from Algiers was tested for the presence of Bartonella species by culture and for the evaluation of the genetic diversity of B. henselae strains by multi-locus variable number of tandem repeats assay (MLVA). Bacteremia prevalence was 17% and only B. henselae was identified. Type I was the predominant type (64%). MLVA typing of 259 strains from 30 bacteremic cats revealed 52 different profiles. 51 of these profiles were specific to Algerian cats/identified for the first time. 20/30 cats (67%) harbored 2 to 7 MLVA profiles simultaneously. The similarity of MLVA profiles obtained from the same cat, neighbor-joining clustering and structure-neighbor clustering showed that such a diversity likely results from two different mechanisms occurring either independently or simultaneously independent infections and genetic drift from a primary strain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bartonella" title="Bartonella">Bartonella</a>, <a href="https://publications.waset.org/abstracts/search?q=cat" title=" cat"> cat</a>, <a href="https://publications.waset.org/abstracts/search?q=MLVA" title=" MLVA"> MLVA</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic" title=" genetic"> genetic</a> </p> <a href="https://publications.waset.org/abstracts/108213/molecular-survey-and-genetic-diversity-of-bartonella-henselae-strains-infecting-stray-cats-from-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108213.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">150</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">32</span> Prevalence of Thyroid Disorders in Pregnancy in Northern Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samira%20Akdader-Oudahmane">Samira Akdader-Oudahmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Assia%20Kamel"> Assia Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Lynda%20Lakabi"> Lynda Lakabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Bruce%20Zimmermann"> Michael Bruce Zimmermann</a>, <a href="https://publications.waset.org/abstracts/search?q=Zohra%20Hamouli-Said"> Zohra Hamouli-Said</a>, <a href="https://publications.waset.org/abstracts/search?q=Djamila%20Meskine"> Djamila Meskine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Iodine is a trace element whose adequate intakes are essential during pregnancy to promote the correct growth and development of the fetus. Iodine deficiency is the cause of several disorders in foetal development, and thyroid disorders during pregnancy are associated with an increased risk of miscarriage or premature birth. The aim of this study was to assess the iodine status and thyroid function of pregnant women (PW) in northern Algeria. Methods: Healthy PW were recruited from an urban area (Algiers). Spot urine and venous blood samples were collected to assess iodine status (urinary iodine concentration, UIC) and serum thyroid hormones (TSH, FT4), and anti-thyroid peroxidase antibodies (TPO-Ab) concentrations. Results: The median UIC for the PW (n=172) in Algiers was 246,74µg/L, 244,68 µg/L, and 220,63µg/L, respectively, during the first, second, and third trimesters of pregnancy. Mean TSH and FT4 concentrations were within reference ranges in all groups of women. Among PW, 72.7%, 75.4%, and 75.5% in the first, second and third trimester were TPO-Ab+. Among PW, 14%, 10%, and 10% in the first, second and third trimester, respectively, with TPO -Ab+ had subclinical hypothyroidism. An analysis of the variations in the levels of the serum parameters (FT4, TSH and anti-TPO antibodies) was analyzed according to the UIC intervals admitted and show that these marker are predictive of thyroid function. Conclusion: In northern Algeria, median UICs indicate iodine sufficiency in PW. About 75% of PW are TPO-Ab+ and the prevalence of subclinical hypothyroidism is high. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thyroid" title="thyroid">thyroid</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnant%20woman" title=" pregnant woman"> pregnant woman</a>, <a href="https://publications.waset.org/abstracts/search?q=urinary%20iodine" title=" urinary iodine"> urinary iodine</a>, <a href="https://publications.waset.org/abstracts/search?q=subclinical%20hypothyroidism" title=" subclinical hypothyroidism"> subclinical hypothyroidism</a> </p> <a href="https://publications.waset.org/abstracts/166232/prevalence-of-thyroid-disorders-in-pregnancy-in-northern-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166232.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">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> A Preliminary Study of the Effects of Abiotic Environmental Variables on Early Diptera Carrion Colonizers in Algiers, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Taleb">M.

However, they are influenced by weather conditions, and their distribution and activity vary according to different time scales, which can affect the post-mortem interval (PMI) estimation. As no data have been published in Algeria on necrophagous insects visiting corpses, two field surveys were conducted in July 2012 and March 2013 at the National Institute for Criminalistics and Criminology (INCC) using rabbit carcasses (Oryctolagus cuniculus L.). The trials were designed to identify the necrophagous Diptera fauna of Algiers, Algeria and examine their variations according to environmental variables. Four hundred and eighteen Diptera adults belonging to five families were captured during this study. The species which were identified on human corpses in different regions of Algeria were also observed on the rabbit carcasses. Although seasonal variations of the species were observed, their abundance did not significantly vary between the two seasons. In addition to seasonal effects, the ambient temperature, the wind speed, and precipitation affect the number of trapped flies. These conclusions highlight the necessity of considering the environmental factors at a scene to estimate the post-mortem interval accurately. It is hoped that these findings provide basic information regarding the necrophagous Diptera fauna of Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic%20entomology" title="forensic entomology">forensic entomology</a>, <a href="https://publications.waset.org/abstracts/search?q=necrophagous%20diptera" title=" necrophagous diptera"> necrophagous diptera</a>, <a href="https://publications.waset.org/abstracts/search?q=post-mortem%20interval" title=" post-mortem interval"> post-mortem interval</a>, <a href="https://publications.waset.org/abstracts/search?q=abiotic%20factors" title=" abiotic factors"> abiotic factors</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/34057/a-preliminary-study-of-the-effects-of-abiotic-environmental-variables-on-early-diptera-carrion-colonizers-in-algiers-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34057.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">389</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Optimization of Interface Radio of Universal Mobile Telecommunication System Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Mohamed%20Amine">O.

In fact, the latest major earthquake that affected the Algiers-Boumerdes region in 2003 caused excessive levels of loss of life and property. Economic, social and environmental damage were also experienced. During the three days following the event, a relatively weak coordination of public authority was noted. Many localities did not receive any relief due to lack of information from concerned authorities and delay in connecting damaged roads. Following this event, Algerian government and civil society has recognized the urgent need for an appropriate and immediate seismic risk mitigation strategy. This paper describes procedures for emergency response following past earthquakes in Algeria and provides a brief review of risk mitigation activities since 1980. The paper also aims to provide measures to reduce earthquake risk through general strategy and practical implementation of the mitigation actions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earthquake" title="earthquake">earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard" title=" hazard"> hazard</a>, <a href="https://publications.waset.org/abstracts/search?q=prevention" title=" prevention"> prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20reduction" title=" risk reduction"> risk reduction</a> </p> <a href="https://publications.waset.org/abstracts/29675/measures-for-earthquake-risk-reduction-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29675.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">529</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Effects of Drought and Anthropism on Vegetation and Soil Elements in the Steppe of Algeria: Case of the Station of Tadmit (Wilaya of Djelfa)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Benseghir">L.

The diachronic study made in Tadmit (50 km south of the district of Djelfa) about the specific recording led us to notice that: The floristic recording of Tadmit is not reduced in time but fluctuate, depending on the pasture intensity, the annual rainfall and especially by the protection area of the following two years from January 2004. The forming specific recording of the station undergo significant changes from a period to another. Those changes in floristic list concern nearly 50% of the initial flora that could disappear or be replaced by new species. Finally, the alfa steppe is in a marked decline and is substituted by new facies that were privileged by the overgrazing, stranding or clearance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=overgrazing" title="overgrazing">overgrazing</a>, <a href="https://publications.waset.org/abstracts/search?q=diachronic%20study" title=" diachronic study"> diachronic study</a>, <a href="https://publications.waset.org/abstracts/search?q=protection%20area" title=" protection area"> protection area</a>, <a href="https://publications.waset.org/abstracts/search?q=climate" title=" climate"> climate</a>, <a href="https://publications.waset.org/abstracts/search?q=desertification" title=" desertification"> desertification</a> </p> <a href="https://publications.waset.org/abstracts/10502/effects-of-drought-and-anthropism-on-vegetation-and-soil-elements-in-the-steppe-of-algeria-case-of-the-station-of-tadmit-wilaya-of-djelfa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10502.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">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Extractive Desulfurization of Atmospheric Gasoil with N,N-Dimethylformamide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kahina%20Bedda">Kahina Bedda</a>, <a href="https://publications.waset.org/abstracts/search?q=Boudjema%20Hamada"> Boudjema Hamada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environmental regulations have been introduced in many countries around the world to reduce the sulfur content of diesel fuel to ultra low levels with the intention of lowering diesel engine’s harmful exhaust emissions and improving air quality. Removal of sulfur containing compounds from diesel feedstocks to produce ultra low sulfur diesel fuel by extraction with selective solvents has received increasing attention in recent years. This is because the sulfur extraction technologies compared to the hydrotreating processes could reduce the cost of desulfurization substantially since they do not demand hydrogen, and are carried out at atmospheric pressure. In this work, the desulfurization of distillate gasoil by liquid-liquid extraction with N, N-dimethylformamide was investigated. This fraction was recovered from a mixture of Hassi Messaoud crude oils and Hassi R'Mel gas-condensate in Algiers refinery. The sulfur content of this cut is 281 ppm. Experiments were performed in six-stage with a ratio of solvent:feed equal to 3:1. The effect of the extraction temperature was investigated in the interval 30 ÷ 110°C. At 110°C the yield of refined gas oil was 82% and its sulfur content was 69 ppm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desulfurization" title="desulfurization">desulfurization</a>, <a href="https://publications.waset.org/abstracts/search?q=gasoil" title=" gasoil"> gasoil</a>, <a href="https://publications.waset.org/abstracts/search?q=N" title=" N"> N</a>, <a href="https://publications.waset.org/abstracts/search?q=N-dimethylformamide" title="N-dimethylformamide">N-dimethylformamide</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfur%20content" title=" sulfur content"> sulfur content</a> </p> <a href="https://publications.waset.org/abstracts/9332/extractive-desulfurization-of-atmospheric-gasoil-with-nn-dimethylformamide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9332.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">386</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Encounters with the Other Sisters of the Past: the Role of Colonial History and Memory in the Adjustment of the Postcolonial Female Identity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatiha%20Ka%C3%AFd%20Berrahal">Fatiha Kaïd Berrahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Ka%C3%AFd"> Nassima Kaïd</a>, <a href="https://publications.waset.org/abstracts/search?q=Djihad%20Affaf%20Selt"> Djihad Affaf Selt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper is a comparative analysis of the Algerian writer Assia Djebar’s women of Algiers in Their Apartment (1982) and the Anglo-Egyptian Ahdaf Soueif’s The Map of Love (1999) foregrounded on the female protagonists’ painfully common colonial and patriarchal experiences, though in different geographical regions of North Africa. This study raises questions pertaining, first, to the emerging contemporary genre “Historiographic meta-fiction” in which the novels examined could be inscribed, then, the interplay of colonial history and personal memory that impinges on the development of the identity of the post-colonial female subject. As the novels alternate between the historical and the autobiographical, we currently seek to understand how it is pertinent and pressing for women to excavate the lost and occluded stories of the past for the adjustment of their present personal identities, which are undoubtedly an important part of the identity of a nation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=postcolonial%20feminism" title="postcolonial feminism">postcolonial feminism</a>, <a href="https://publications.waset.org/abstracts/search?q=islamic%20feminism" title=" islamic feminism"> islamic feminism</a>, <a href="https://publications.waset.org/abstracts/search?q=memory" title=" memory"> memory</a>, <a href="https://publications.waset.org/abstracts/search?q=histoirographic%20metafiction" title=" histoirographic metafiction"> histoirographic metafiction</a> </p> <a href="https://publications.waset.org/abstracts/19905/encounters-with-the-other-sisters-of-the-past-the-role-of-colonial-history-and-memory-in-the-adjustment-of-the-postcolonial-female-identity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19905.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">644</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Numerical Evaluation of the Degradation of Shear Modulus and Damping Evolution of Soils in the Eastern Region of Algiers Using Geophysical and Geotechnical Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Khiatine">Mohamed Khiatine</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramdane%20Bahar"> Ramdane Bahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research performed during the last years has revealed that the seismic response of the soilis significantly non linear and hysteresis to the deformationsitundergoes during earthquakes and notably during violent shaking. This nonlinear behavior of soils can be characterized by curves showing the evolution of shearmodulus and damping versus distortion. Also, in this context, geotechnical seismic engineering problems often require the characterization of dynamic soil properties over a wide range of deformation. This determination of dynamic soil properties is key to predict the seismic response of soils for important civil engineering structures.

This disease is very common in young birds beyond the second week of life, especially in land-based breeding. The study was carried out in a hunting center of Zeralda located in the north-east of Algiers. The objective of our work is to study the evolution of coccidiosis in quails from 1 to 35 days old by collecting their droppings daily. These are analyzed in the laboratory using the flotation method and the Mac Master one to count coccidia. Weight changes are taken into account as well as mortality in parallel with certain zootechnical parameters such as density. The species of coccidia recovered is Eimeria coturnicis. The results showed that there is an average evolution of mortality of individuals with a rate of 13.33% due to the presence of coccidia with a significant regression (p=0.031). The weight of the quails increases with the age of the animal with a rapid growth rate from the 3rd week onwards.
