En condition de carence en azote Medicago truncatula a la capacité d’établir une interaction symbiotique avec la bactérie du sol fixatrice d’azote Sinorhizobium medicae. Au cours de cette association un nouvel organe racinaire est formé, la nodosité fixatrice d’azote, cette dernière est infectée de manière massive et chronique par les bactéries sans qu’aucune réponse immunitaire soit enclenchée. Nos recherches ont portées sur l’étude d’une famille de gènes les Pathogenesis Related protein (PRs) et leur implication au cours des interactions Medicago-microorganismes, dont la symbiose et la sénescence. Des approches d'analyses de génomiques, protéomique, transcriptomique et phylogénétique ont été réalisée. Nous résultats montre que cette famille de gènes comporte 66 membres répartie essentiellement entre les PR5 et PR10. Dérivant de plusieurs ancêtre, ces gènes sont induit de manière différentielle en réponse au pathogène, au cours de la symbiose et au cours de la sénescence des nodosités (processus de destruction). Nos résultats constitues la première description de cette famille et souligne l’importance de ces gènes au cours des interactions avec les microorganismes. De plus certain PRs semble jouait un rôle important au cours de la symbiose et de la sénescence. Notre travail montre de manière claire que la sénescence fait intervenir des phénomènes immunitaires.

Portland limestone cement, PLC, has been produced by inter-grinding clinker with crushed limestone and gypsum. The crushed limestone introduced in PLC manufacturing as a partial replacement of the clinker serves in conserving energy and reducing CO2 emissions. Since CO2 is a main greenhouse gas that contributes to global warming, its reduction has gained attention. Therefore, the importance of PLC appears in improving concrete sustainability through reduction in greenhouse gas emissions and energy consumed in the cement industry. Europe, Canada and U.S.A took the lead in developing research studies upon allowing the incorporation of limestone in Portland cement. Currently, Egypt is taking steps into the production of PLC to promote a sustainable and environmentally friendly concrete. Yet, little work has been conducted on PLC while other international attempts on its incorporation did not tackle heavily it interaction with admixtures.This work aims primarily at investigating the performance of Portland limestone cement concrete incorporating chemical and mineral admixtures. Sixteen concrete mixtures were prepared with various levels of limestone while incorporating plasticizing admixtures and silica fume. The experimental program involved testing Portland cement, fresh concrete and hardened concrete. The tests performed on hardened concrete were, compressive strength, flexural strength, resistance to chloride ion penetration, sulphate and corrosion attacks.Results of this work reveals a somewhat similar behavior of PLC concrete when compared to OPC concrete with regards to compressive and flexural strength; yet, strength decreased with higher incorporation of Portland limestone cement. Furthermore, addition of superplasticizing agent and silica fume had the highest compressive and flexural strength values. Portland limestone concrete outperformed conventional concrete upon exposure to chloride ion penetration. The increase in limestone cement incorporation with the addition of superplasticizer and silica fume admixtures reduced the chloride permeability the most. It also demonstrated a lower mass loss and strength reduction upon exposure to sulphate attack. Lower corrosion risk was attained by PLC concrete compared to conventional concrete. Future work needs to be performed to investigate long term behavior of PLC concrete’s resistance to carbonation, elevated temperatures, freeze and thaw. Effectiveness of other chemical and mineral admixtures such as fly ash and blast furance slag should be examined in order to evaluate PLC’s performance upon their incorporation. Applicators are encouraged to make use of PLC concrete in non-strategic structures in an attempt to improve concrete’s sustainability and alleviate negative environmental impact.

AbstractToday, the Feminine Divine returns into the scene in different domains such as arts, media,music, movies, and literature. The Feminine Divine or the Sacred Feminine becomes a newtrend in contemporary literature. Different authors start to challenge the traditionalrepresentation of the divine and give a new radical representation of divinity. Sue Monk Kiddand Dan Brown are among those authors who give a new representation of the Divine in theirworks. This dissertation is intended to examine the how Kid and Brown have represented theFeminine Divine in their novels The Secret Life of Bees and The Da Vinci Code. In addition, italso analyses the new role of women in the novels. In order to find answers to the researchquestions, the analytical approach and feminist theology are used. The result of this studyshows that in both The Da Vinci Code and The Secret Life of Bees the divine was representedas feminine. For The Da Vinci Code, the divine is represented through Mary Magdalene afemale character, while in The Secret Life of Bees the divine is represented through the BlackMadonna a female and black character.
