Étude comparative des caractéristiques florales de quelques familles botaniques.
No full textOur work is carried out in the biology laboratory in center University Abdelhafid Boussouf Mila. The main objective of this study is to make a parison of the characteristics flowers of some botanical families (44 species) . For that we started with collection of the flowers of the species things carried out the study. The observation focused .first, on the general morphology of the flower (sepals, petals, number of stamens, ovary situation) and their symmetry (Actinomorphe, Zygomorphe ).Then the binocular observation of the reproductive organs stamens, ovary). Finally, the realization of a floral dissection allowed us to obstruct the floral diagram and lastly the floral form. Indeed, the number of floral picies makes it possible to distinguish the suiving categories:- Tetrameric species Oleaceae ( Jasminum fruticans L.); - Pentameric species Rosaceae (Prunus armonia L.);
- Hexameric species Solanaceae (Solarum caperi L.).Notre travail est réalisé au laboratoire de biologie au Centre Universitaire Abdelhafid Boussouf-Mila. Cette étude a pour principal objectif de faire une comparaison des caractéristiques florales de quelques familles
botaniques (44 espèces). Pour cela nous avons commencé par la collection des fleurs des espèces choisis et nous avons procédé à l’étude. Les observations ont portée d’abord, sur la morphologie générale de la fleur (sépales, pétales, nombre d’étamines, situation d’ovaires) et leur symétrie (Actinomorphe, Zygomorphe), puis l’observation sous binoculaire des organes reproducteurs (étamines et ovaires). Ensuite, la réalisation d’une dissection florale nous a permis d’obtenir le diagramme floral et dernièrement la formule florale. En effet, le nombre des pièces florales permet de distinguer les catégories suivantes: - Des espèces Tétramères : léacées (Jasminum fruticans L.) ; - Des espèces Pentamères : Rosacées (Prunus armeniaca L.) ; - Des espèces Hexamères : Solanacées (Solanum lycopersicum L.)
Cartographie des champs de concentration du nitrate dans la plaine d’Ain Oussara Djelfa
No full textThe plain of Ain Oussera in the central region of the Algerian high steppe plains, is a typical case of semi-arid to arid regions, it is located in an area where the mobilization of surface water is zero and the water needs for different uses are ensured by the exploitation of groundwater. These latter components of physico-chemical parameters first reflect the geological environment in which it circulates; and especially nitrates are more likely to vary over time, because they are more directly related to human activities.
The memory on which we are going to work, which considers that the use of GIS means is important by using geostatistical methods (kriging) for the mapping and analysis of environmental risk, through a study of the concentration of nitrates « NO-3 »On the plain of Ain oussera. The usual interpolation methods are discussed, as well as the added value of the geostatistical approach. From the measurements and additional information available, geostatistics makes it possible to map the concentrations in the field of study, while associating with this mapping an estimate of the confidence that can be given to it, the uncertainty associated with the process of spatial prediction being inevitableLa plaine de Ain Oussera dans la région centrale des hautes plaines steppiques Algériennes, est un cas typique des régions semi-arides à arides, elle se trouve dans une zone où la mobilisation des eaux uperficielles est nulle et les besoins en eau pour les différents usages sont assurés par l’exploitation des eaux souterraines. Ces derniers composant des paramètres physico-chimique reflète d’abord le milieu géologique dans lequel elle circule; et surtout les nitrates sont plus susceptibles de varier dans le temps, parce qu’ils sont plus directement liés aux activités humaines.Le mémoire sur laquelle nous allons travailler, qui considère que l'utilisation des moyens SIG est importante en utilisant des méthodes géostatistiques (krigeage) pour la cartographie et l’analyse du risque environnemental, à travers une étude de concentration du nitrates « NO-3 » sur la plaine d’Ain oussera. Les méthodes usuelles d’interpolation sont discutées, ainsi que la valeur ajoutée de l’approche géostatistique. A partir des mesures et des informations complémentaires disponibles, la géostatistique permet de cartographier les concentrations sur le domaine d’étude, tout en associant à cette cartographie une estimation de la confiance que l’on peut lui accorder, l’incertitude associée au processus de prédiction spatiale étant inéluctabl
Etude hydrologique et hydrotechnique d’un barrage sur un Oued. Cas du barrage d’Oued Selsou.Tolga.W.de Biskra
No full textAlgeria has been experiencing fairly marked water stress for several years, which has led to the establishment of a vast water mobilization program. As part of the national water conservation strategy and in order to obilize the millions of cubic meters of water that is lost (discharge into the sea). The National Agency for Dams and Transfer has seen dams constructed. However, the study, choice and sizing of storage structures deserve to be
deepened. Thus, the study that we conducted in this graduation project which involved an indepth study of the process of building a small dam for irrigation in the municipality of Tolga located in the Wilayat of Biskra. After carrying out a hydrological study, followed by an indepth hydrotechnical study, we dimensioned our earthen structure with a core having a height of 27.82 m and a storage capacity of 6370000 m3.L'Algérie connaît depuis plusieurs années un stress hydrique assez marqué, ce qui a conduit à la mise en place d'un vaste programme de mobilisation des eaux. Dans le cadre de la stratégie nationale en matière de conservation des eaux et afin de mobiliser les millions de mètre cubes d’eau qui est perdus (rejet en mer). L’Agence Nationale des Barrages et Transfert s’est vue réaliser des barrages. Toutefois l’étude, le choix et le dimensionnement des ouvrages de stockage méritent d’être approfondis. Ainsi, l’étude que nous avons menée dans ce projet de fin d’études qui portait sur une étude approfondie du processus de construction d'un petit
barrage pour l'irrigation dans la commune de Tolga située dans la wilaya de Biskra. Après avoir fait une étude hydrologique, suivi d’une étude hydrotechnique approfondie nous avons dimensionné notre ouvrage en terre avec un noyau ayant une hauteur de 27.82 m et une capacité de stockage de 6370000 m3

A Dissertation Submitted in Partial Fulfillment for the Requirement of the Master Degree in Didactics of Foreign Languages
No full textLiterature is very important to the process of language learning. It plays a vital part in enriching students' vocabulary, their critical thinking, increasing their knowledge about the culture of the target language and developing their intercultural communication. Since the field of language teaching has started giving attention to promoting students’ intercultural competence, the literature classroom can be considered as the best tool for teaching and promoting intercultural competence to EFL learners. This study aims to investigate and explore the extent to which interculturality can affect the teaching of literature. To collect data and information needed for this subject, the research opted to use both quantitative and qualitative methods. A questionnaire is submitted to forty five (45) third year students at Abdelhafid Boussouf, Mila University Center and an interview is conducted with seven (07) Master Two students at the same university center. The obtained data were analyzed. The results of the data showed that most students benefited from literature to develop their intercultural awareness and many of them preferred including interculturality in the literature classroom. From the findings, it can be seen that students became capable of grading their level of intercultural awareness. The results of this study highlighted the positive effects of interculturality in the literature classroom on students

Broadcast efficace dans les cycles
No full textLet G be a graph and Cn a cycle of order n, a dominating set in a graph G is a subset D of vertices of the graph G such that any vertex belongs either to this set or to a neighbor in this one . The broadcast domination problem is a variant of domination problem. A broadcast f is efficient as a broadcast invariant if every vertex in G is f-dominated by exactly one vertex. In this work, we study the number of different efficient broadcasts that we denote by N eb(G) in a cycle Cn . We determine either bounds or exact valuesSoit G un graphe et Cn un cycle d’ordre n de longueur n, un ensemble dominant dans un graphe G est un sous-ensemble de sommets du graphe G tel que tout sommet appartient soit à cet ensemble soit a un voisin dans celui-ci. Le problème de la broadcast domination est une variante du problème de domination. Un broadcast f est efficace qui est un invariant de broadcast si tout sommet est f-dominé exactement par un seul sommet f-dominant. Dans ce travail, nous étudions le nombre de differents broadcasts efficaces qu’on le note N eb dans un cycle Cn. Nous déterminons soit des bornes soit des valeurs exacte
