The research focuses on complementary analyzes to measure the attractiveness and frequentation of the network of squares structuring the colonial space in Sétif: The three places “Sahat El Istiklal ", " Masdjid Ibn Badis ", and "Moudjahid Museum". These are chosen for their historical dimension. The spatial syntax, the "in situ" observation and the field survey as well as the study of the Gaussian curve constitute the complementary analyses. Spatial syntax, using the "DepthMap" software, carries out global and local axial studies for the description of visual movement axes determining the topological significance of each place. Graphical visual analysis (VGA) superimposed on the actual flow of pedestrians allows for levels of visual integration of each square in relation to its own configuration. The 'in situ' observation and field survey complements the syntactic analysis by characterising the user profile and current uses at each square. The research also refers to the Gaussian curve graphically representing the distribution of the series of selected attractiveness and frequentation variables (VAF), constituting the basis of a resonance state or probable state confirming the results obtained. These complementary analyses measure the shifts in the attractiveness and frequentation of the three squares. They allow us to broaden the discussion initiated by them in an urban environment and to establish causal relationships between spatial configuration and human behaviour in order to contribute to the development of innovative recommendations. Keywords: city center, public square, spatial syntax, attraction and frequentation variables (AFV), "in situ" observation and field survey, Gauss curve and resonance state.

In Algeria, solid waste management (SWM) is considered a major problem; most of this waste is dumped in landfills without any control. The Algerian authorities have developed a national strategy for the integrated management of urban solid waste by 2035 by working on the implementation, development and equipping of technical landfill centers (TLC). Therefore, the aim of this study was to help local authorities in choosing the optimal locations for the completion of the proposed TLC between municipalities. This research used a combination of the multicriteria decision aid (MCDA) and geographic information systems (GIS). It combines two aggregation methods: Linear Combination of Weights (WCL) and Criteria Weighting. The analytical hierarchy process (AHP) pair-wise comparison method was applied for assigning weights to the 11 criteria that were divided into environmental, social, and economic criteria according to previous studies in the field and the characteristics of the HODNA area. The results showed that 22.56% is the most suitable location for a landfill site, especially on the southeastern side, while 20.70% was suitable and 18.40% was moderately suitable. Finally, the process of assessing the spatial suitability of public emptying sites based on the results obtained in the final digital map,4.76% of the landfill sites are located in inappropriate areas, 14.29% are located in less suitable areas, 33.33% are located in suitable areas, 33.33% are located in moderately suitable areas and 14.29% are located in very suitable areas.

Abstract: The study aims to evaluate the efficiency of the tram track in the urban transport system of the Algerian city of Setif by combining Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) approach. In this research, a set of multiple pre-determined criteria applicable in the field of urban transport were selected for decision-making. They were collected from recent research literature and expert opinions in this discipline, and then were arranged and evaluated in the AHP to extract the main weights for each criterion. In the end, they were processed spatially by using GIS. The study showed that the selection of the tramway track in the city of Setif was not successful in terms of the chosen location, and its selection was not studied according to the efficiency and quality criteria applicable in the field of urban transport. In addition, the study concluded that there is a significant shortfall in the first tram track, especially the one linking the tram route to the northern and southern parts of the city, which affected the efficiency and quality of the tram route. As the results have shown, the percentage of good spaces near the tram route does not exceed 0.34%. It is followed by the percentage of the average and acceptable areas (13.48%) and then the percentage of the marginalized areas and the areas far from the tram track (86.18% of the total area of the city). The study also demonstrated the importance of using AHP and GIS in evaluating a completed tram track according to a comprehensive and widely studied scientific methodology. Keywords: urban transport; transport decision-making; AHP; GIS; tramway Setif

This study investigates a synergistic treatment comprising alkali, permanganate, dichromate, silane and bleaching pretreatment on Luffa sponge (LF) fibers intended to be used as reinforcement in an unsaturated polyester (UP) matrix to improve the mechanical properties of Luffa sponge fibers reinforced unsaturated polyester composites. Treatment effects by NaOH (5 wt%), K2Cr2O7 (0.2 wt%), KMnO4 (0.0125 wt%), NaClO (13°) and silane (0.5 wt%) on the performance of the prepared composites were evaluated by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), SEM and mechanical tests (flexural strength and modulus). The results of the analyses indicated that composites reinforced with treated fibers have higher flexural strength than composites reinforced with untreated fibers. Keywords: Luffa fiber, composite, alkali treatment, flexural strength

Abstract-This paper proposes the integration of GIS (Geographic Information System ) and HMA (Hierarchical Multi-criterion Analysis) offering a low-cost methodology to produce vulnerability maps. The quintessential role the rivers play in urban development has long been asserted and accepted. However, one of the subsequent consequences of these urban development activities is the increased frequency of floods. The case in point is the city of M’sila, Algeria. The subject city was settled along the banks of a river known as Oued El Ksob, which undoubtedly had a significant influence on its development. In the last 50 years, M’sila has experienced significant spatial growth, especially in its north and northwest sides. As such, the work presented in this article aims to assess the vulnerability of the city to the risks of flooding. The approach used is based on the combined use of the HMA method coupled with the GIS. The process allowed the graphical representation of the resulting analysis of complex data of the territory, i.e. the mapping of its vulnerability to flooding. The map has four vulnerability categories ranging from low to very strong. The proposed system serves as an essential decision-making tool for local government officials. Keywords-flood risk;

This work is part of the development of local materials, such as vegetable fiber (palm fiber) and red clay from southern Algeria, widely used in the preparation of bricks as rural building materials. Vegetal fibers have very interesting properties, they are: renewable, biodegradable and low cost / lightness ratio. Their mechanical properties are very important. However, the predominant problem in this type of composite material is the weak adhesion of the matrix-fiber interface, probably attributed to the nature of the surface and the hydrophobic character of the natural fibers, thus leading to weak mechanical properties for the material, envisaged composite. The purpose of this study is to treat palm fiber with a basic solution of sodium hydroxide (4% w/v NaOH) for varying periods of time: 3, 7, 24 and 48 hours to improve interfacial adhesion. The results obtained from the tests carried out on the composite reinforced with palm fibers treated during 7 hours, showed a clear increase as regards the resistance to bending and compression; it is respectively of the order of 57 and 60%, compared to the composite reinforced by the untreated fibers. It can be deduced that palm fibers can be considered as one of the suitable materials for clay reinforcement. Key words: palm fibers / clay red / flexural strength / compression / composite

Résumé Le territoire national est soumis aux inondations qui se manifestent de façon catastrophique, constituant ainsi une contrainte majeure pour le développement économique et social du pays. D’après le recensement effectué par les services de la protection civile le phénomène concerne une commune sur trois (485 communes) qui est susceptible d’être inondée en partie ou en totalité. Dans les territoires du Hodna, les conditions climatiques, la nature endoréique du bassin versant et l’urbanisation des zones inondables présentent des facteurs très importants pour le risque d’inondation. La périurbanisation au sein de la plaine du Hodna aux versants instables pose des problèmes spécifiques auxquels les pouvoirs publics tentent de faire face, d’où l’adoption d’une série de mesures en juillet 2003, qui a conduit à l’institution de la loi 04-20 du 25 décembre 2004 relative à la gestion des catastrophes dans le cadre du développement durable. M’sila, ville moyenne de l’intérieur du pays, située dans le bassin versant du Hodna est soumise à de nombreuses inondations, qui combine un accroissement urbain très rapide et des versants particulièrement dynamiques est représentative de ce rapprochement entre les aléas naturels et les activités humaines. L’étude diachronique de l’évolution de l’occupation du sol de 1970 à nos jours montre la densification des infrastructures dans cette ville. Cette étude se propose de mener une réflexion sur la thématique dela maîtrise de l’urbanisation, au regard des risques naturels dits majeurs. Les questions développées ont pour objectifs d’une part d’informer sur le niveau de résilience de la ville par rapport à des scénarios d’inondation et, d’autre part, d’aider les autorités locales et nationales à prendre les décisions adéquates. Mots-clefs: inondations, croissance urbaine, risque, plaine du Hodna, petites et moyennes villes

This article describes a study conducted to determine the ideal both traditional and stabilized composition of adobe as a building material, and to further refine an appropriate choice of coating composition for extended durability of these constructions in adobe: choose the suitable coating that fits the most with its substrate. The constructions in Z’gueg El Hadjadj [Laghouat town, Algeria] consist of adobe walls but also plaster that serves as a coating for these brick walls. The degradation phenomena of the building are considered in the adobe-coated couple, and consequently in the suitability of their compositions. The compatibility of plasters with adobes remains a major factor in the restoration and conservation of earthen constructions. This paper examines the results of the experimental characterization of the behavior of coated bricks, which consists of studying in the laboratory the water resistance: the drying-wetting test and the capillary rise test, as well as the complementary accelerated aging test: the abrasion test. These tests will be supplemented by another test, that of the adhesion, to see the compatibility of the coatings with their supports. The results, compared below, led to the conclusion that for capillary absorption and adhesion tests, a homogeneous coating in 3 layers could give more conclusive results. The drying-wetting test is recommended especially for bulk and surface treated samples. Keywords: adobe brick / coatings / absorption / adhesion / durability

Résumé Cette étude propose une démarche d’analyse spatiale de l’armature urbaine des villes importantes du Hodna notamment ; M’sila, Barika. Il s’agit de dégager les logiques de déploiement spatial de l’armature urbaine tout en explicitant une réalité de terrains souvent négligée, par la prise en compte de toutes les formes d’agglomération ainsi que des logiques d’acteurs (Etat, pouvoirs locaux traditionnels, populations, etc.). L’objectif de cette recherche est de mettre en évidence la dynamique urbaine dont l’axe M’sila-Barika fait l’objet depuis quatre décennies. L’irruption progressive, dans les « campagnes » proches, de logiques d’économies urbaine et l’effacement à leur profit des formes traditionnelles de mise en valeur de leurs espaces, l’intensification des mobilités entre villes et campagnes sont autant d’éléments de cette dynamique qu’il est nécessaire de prendre en compte pour mieux comprendre cette nouvelle donnée. Pour atteindre cet objectif, une place importante est accordée à la démarche multi-échelles afin d’aborder les dynamiques en cours dans toutes leurs dimensions à partir de la compréhension des villes à travers le temps, les événements et les cultures, qu'à l'époque traditionnelle, chaque société détenait un type bien déterminé d'organisation spatiale, fonctionnelle ou encore sociale. Ce travail s’achève par une mise en perspective de la dynamique à venir en général et sur l’axe M’sila-Barika en particulier. Mots-clés : M’sila, Barika, armature urbaine, acteurs, dynamique urbaine.

Composite materials based on woven Alfa and unsaturated polyester resins were manufactured by hand layup technique. The Alfa fibers were collected from the M’Sila region (Algeria). Different chemical treatments such as mercerization, permanganate, acetylating and dichromate have been used in order to modulate the mechanical properties of these composites. According to tensile and flexural tests, the treated composites showed better mechanical performances compared to their untreated counterparts. Actually, the permanganate treated fiber-reinforced composites showed 43.02 % of increase in tensile strength and 31.59 % in Young’s modulus, while the acetylated fiber-reinforced composites showed maximum improvement in flexural strength of about 23.80 %. Furthermore, the flexural modulus was also improved by 35.7 % compared to the untreated Alfa fiber composites. FTIR characterization of Alfa fibers showed that the quantity of hydroxyl groups (-OH) decreased and the crystallinity index increase by 20.53% after alkali treatment. SEM observations on fibers surface showed that the different chemical treatments modified the fiber which improved the fiber–matrix adhesion. Keywords: . Alfa fibers, composites, chemical treatment, tensile test, mechanical properties.

This study provides a spatial analysis approach to the urban framework of Hodna cities, especially; M'sila. It is logical to identify spatial deployment of the urban framework while explaining a fact often neglected land, by taking into account all forms of agglomeration and logic of actors (state, local governments traditional, people, etc.). The ultimate goal is to highlight the urban dynamics, whose M'sila has been the subject for forty years. The gradual emergence, in nearby countryside, logical urban economies and erasing, for their benefit, traditional forms of development of their areas, increased mobility between cities and countryside are all elements of this dynamic that it is necessary to take into account to better understand this new data. To achieve this goal, an important place is given to the multi-scale approach to address the dynamics in all their dimensions from the understanding of cities through time, events and cultures, as in traditional times, each society had a well-defined spatial, functional or social organization types. This paper concludes with a perspective of the future dynamics in general and on the city of M'sila in particular. Keywords City; M’sila; Urban Center; Growth of Population; Mobility

RESUME. L'un des problèmes majeurs que connait l'Algérie demeure celui de la gestion des déchets solides urbains et de l'urbanisation non maitrisée. Dans la région du Hodna le phénomène semble être plus important dans les centres urbains en raison de l'énorme quantité de déchets solides générés par les activités domestiques et commerciales. Dans la plupart des villes algériennes, les déchets solides ne sont pas seulement entassés dans des quantités énormes sur les décharges, mais aussi, déversés indistinctement dans les cours d’eau, dans les espaces publics et aux bords des rues. En Algérie, avant l'an 2000, la gestion des déchets solides urbains n'était pas considérée comme une priorité nationale et où le pays vivait une crise écologique sévère : Dégradation du cadre de vie, intensification de pollutions diverses, prolifération des déchets urbains et industriels, gestion inadéquate des déchets…etc. Les pratiques de gestion des déchets pendant cette période ont porté principalement sur l’élimination des déchets. Le faible accent qui a été accordée à la gestion des ces déchets a entraîné des impact négatif sur l'environnement, l'eau et la santé publiques. Ce n'est qu'en 2002 que le gouvernement algérien a adopté une stratégie nationale de gestion des déchets. Malheureusement , Le constat d’aujourd’hui est qu’aucune solution satisfaisante intégrant les aspects environnementaux, législatifs, financiers, n’a encore été adapté. Devant l’accroissement des villes liés aux problèmes de l'urbanisation non maîtrisée, le développement industriel et l’évolution des modes de vie induisant une production croissante des déchets, les techniques de gestion de ceux-ci, utilisées jusqu'alors dans les milieux urbains, méritent d’être reconsidérées. C'est dans cette optique que cet article se propose d'étudier et d'analyser dans une approche spatio-temporelle, les pratiques de gestion des déchets solides urbains dans la ville de M’sila en vu d'évaluer l'état d'une telle gestion et de dégager les éléments clés d'une planification intégrée de gestion de ces déchets. . MOTS CLES. gestion, déchets solides urbains, environnement, urbanisation, cadre de vie.

Dealing with major risks has become one of the most important challenges for sustainable urban development in the light of rapid urbanization, which touched most of Algerian cities and led to a doubling of human, material, economic and environmental losses, which in turn led to the deterioration of the urban fabric. Since the early 1960s the city of Bou Saada underwent a fast, chaotic and unplanned urban evolution over 65% of its surface, most of which is located on slopes-slopes of mountains, of valleys-and near the sand dunes, being thus exposed to the risk of flooding, rockfalls and desertification. A morpho-dynamic analysis shows that this is linked to the physical environment on the one hand and, on the other hand, human activities like rapid population growth in urban areas, the ambiguity of the real estate Algerian slums and the various irresponsible types of configuration carved these dangers and increased their severity in the urban system. In order to reduce their harm, these natural hazards must be understood, their impact on the urban area determined and the urban agglomerations must be protected from their effects.

ABSTRACT Many economic researchers are using several methods and indicators in an attempt to measure sustainable development at the level of each city, where indicators evaluate the state of each of them through numeric criteria that can be calculated and compared with the other cities, and I have multiplied these indicators to social, environmental, economic, placing so many indicators of sustainable development has become a necessity to form the basis of interest for the management of all sustainable development aspects. El Eulma City, about 300 km away from the Algiers to the east, and 25 km away from the headquarters of the state of Setif heading Algerian cities in terms of economic mobility business that made her stand out as an economic trade pole at the national level and at the level of the Algerian East (the regional level). We have emerged this commercial economic movement in the city of El Eulma without prior planning to make it grow and expand at the expense of residential property in inappropriate places and is not intended for trading (ie, at the expense of areas the public's residential neighborhoods), the most important district of Dubai, through which the city became a witness of intensive movement because of the growing demand as a shift from commercial neighborhood to another resulted in the neglect of environmental and social aspects will therefore be through this study set commercial indicators for economic movement within the urban fabric where residential property is in order to achieve sustainable development of the city integrates the face of economic with the face of environmental and social. Keywords: economic and commercial mobility, real estate upgrade, upgrade housing, indicators of economic activity, sustainable development.

ABSTRACT Dealing with major risks has become one of the most important challenges for sustainable urban development in the light of rapid urbanization, which touched most of Algerian cities and led to a doubling of human bets, material, economic and environmental, which in turn led to the deterioration of the urban fabric. Since the early in 1960’s the city of Bou Saada underwent the evolution of fast, chaotic and unplanned urban form today including 65%, most of which is located on the slopes, the slopes of the mountains, the edges of the valleys and near the sand dunes, and thus exposed to the risk of flooding, the collapse of the stones and desertification. Analysing the morpho - dynamic aspect shows that this is linked to conditions of physical material on the one hand and human activities like rapid population growth in urban areas and the ambiguity of the real estate Algerian slums and irresponsible various types of configuration on the other hand carved these dangers and increased aggravation in the urban, and to reduce its harm, these natural hazards must be known and their impact on the urban area must be determined and the urban agglomerations must be protected of its effects. Key words natural hazards, urban environment, flooding, collapse of the stones, desertification.

Résumé. Le territoire national soumis aux inondations se manifestent de façon catastrophique constituant ainsi une contrainte majeure pour le développement économique et social du pays. D’après Le recensement effectué par les services de la protection civile une commune sur trois (de 485 communes) est susceptible d’être inondée en partie ou en totalité. Ces inondations sont les catastrophes naturelles les plus fréquentes et les plus destructrices, provoquant d’importants dégâts humains et matériels. La prévention contre ces risques représente un intérêt particulier pour le développement durable du pays. Face à l’accroissement du risque, seul une action volontaire parait appropriée, fondée sur le constat que la prise en compte des inondations dans l’aménagement et le développement du territoire ne peut se limiter à une approche trop locale, sectorielle et à court terme, mais elle suppose une politique globale de prévention des risques naturels. Une série de mesures a donc été définie en juillet 2003, qui a notamment conduit à l’institution de la loi 04-20 du 25 décembre 2004 relative à la gestion des catastrophes dans le cadre du développement durable. L’apport principal de cette étude est de dégager des pistes de réflexion qui nous permettent de s’appuyer sur un socle scientifique solide pour la fabrication d'une ville résiliente aux risques d'inondations. Les questions développées dans cette recherche, ont pour objectifs d’une part d’informer sur le niveau de résilience de la ville par rapport à des scénarios d’inondation, d’autre part d’aider les pouvoirs publics à prendre les décisions adéquates aux temps nécessaires afin d'augmenter le niveau de résilience des milieux urbains et de montrer que d’autres voies méritent d’être explorées afin de sortir de l’impasse actuelle exprimée par la hausse du coût des dommages. Mots clés: Inondations, gestion, risque, résilience urbaine, aide à la décision,

Résumé إن تعميم أنماط البرامج من السكن التطوري، التساهمي والاجتماعي وغيرها على مستويات مختلفة من مناطق الوطن دون مراعاة الشروط و الخصوصيات الثقافية ، الاجتماعية الاقتصادية و المناخية، خاصة بالمناطق الصحراوية أدى إلى عدم التكامل و التناسق بين النسيج العمراني الأم و النسيج العمراني المتداخل للأحياء الناتجة عنها ، حيث لم ترق هذه الأحياء السكنية الجديدة إلى مشاريع عمرانية لافتقارها إلى التجهيزات و المرافق الضرورية و نقص التهيئة الخارجية ، وتعرضها للتشوه العمراني و المعماري، وغياب النظرة التكاملية بين هذه الأنماط و العوامل المناخية الصعبة المميزة للمدن الصحراوية . تتناول هذه الدراسة تحليل هذه البرامج السكنية و الآثار المترتبة عنها داخل المحيط العمراني والبيئي بغية تقديم التوصيات الضرورية التي تأخذ بعين الاعتبار خصوصيات حالة الدراسة مدينة بوسعادة، من خلال تحليل أحياء سكنية ثلاثة: اجتماعي ، تطوري و اجتماعي تساهمي.

ملخص إن ثلث سكان العالم يعيشون في المباني الطينية مع تنوع موادها و تقنياتها المستخدمة, كما تمثل هذه المباني 20 % من المواقع الثقافية لليونسكو التي تحظى بإعجاب العالم والمدرجة في قائمة تراثها العالمي, لهذا فان الخبراء في الهندسة المعمارية و المدنية للبناء بالطين وجهوا نداءات في عدة مؤتمرات دولية مبرزين دور المجتمعات وضرورة مواصلة التزامها في صيانة وترميم المباني الطينية القائمة, كما أنهم دعوا لجنة التراث العالمي لتعزيز مكانة الهندسة المعمارية والمدنية للبناء بالطين في إطار الحفاظ على التراث الثقافي. وتبذل في الوقت الراهن جهود مشتركة ترمي إلى حماية وتطوير الهندسة المعمارية للبناء بالطين وتقنيات التشييد مثلما تعمل اليونسكو في هذا المجال. ففي هذا الإطار يأتي هذا الموضوع ليتناول بطريقة تحليلية ونقدية مجموعة من التجارب العلمية التي اهتمت بفهم متانة المواد الطينية وكذا فهم ظواهر تفتيتها وتعريتها من التلبيس الخارجي جراء تعرضها للعوامل الخارجية المناخية و الاجتماعية, كما هو الحال بالمدينة الطينية العتيقة – قصر بوسعادة– بالجزائر التي يرجع تأسيسها إلى القرن الرابع عشر ميلادي, و التي تمثل إرثا هاما في العمارة الطينية. حيث تهدف هذه الدراسة إلى إيجاد التوصيات و التوجيهات الضرورية لترميم و تطوير مواد البناء الطينية لصيانة المباني الموجودة وتصور مشاريع مستقبلية تحقق الأصالة وتضمن المعاصرة و الاستدامة. الكلمات المفتاحية: مواد البناء, العمارة الطينية, المتانة, التعرية, الترميم, التطوير, التراث, الاستدامة.
