Contribution to the valorisation of harbour dredging sediments : road construction, concrete and artificial aggregates
Face aux problématiques de gestion des sédiments de dragage portuaire, aujourd'hui, il apparait nécessaire de trouver des solutions potentielles de valorisation permettant de répondre efficacement à ces problématiques. La valorisation en génie civil, des sédiments des port de Saint Louis et de Dunkerque, présente une solution alternative à la gestion de ces matériaux. les travaux menés dans le cadre de cette thèse se focalisent d'une part, sur la valorisation des sédiments de Saint louis en technique routière et d'autre part, sur la valorisation des sédiments de Dunkerque en béton ainsi qu'en granulats artificiels. Après la caractérisation physico-chimique, minéralogique et mécanique, l'impact environnemental des sédiments bruts du Port de Saint Louis et le potentiel d'utilisation de ces matériaux en technique routière sont évalués. L'étude de formulation de matériaux, pour une utilisation en couche de fondation, s'est fondé sur une méthode expérimentale de détermination de compacité maximale. les mélanges granulaires optimaux remplissent les conditions d'utilisation en couche de fondation sont ensuite évalué au travers d'essais de lixiviation. La partie béton concerne la formulation des bétons à base de sédiment. Après la caractérisation de ces matériaux, trois bétons ont fait l'objet d'une étude de durabilité face à l'attaque sulfatique externe associé à une caractérisation non destructive en vue d'étudier l'influence d'incorporation des sédiments sur les propriétés des bétons. La partie granulats artificiels présente d'étude de faisabilité de granulats à base de sédiments, l'assiette granulaire et la technique de big-bag sont les deux méthodes de confection utilisées.In front of problems of management of harbour dredging sediment, today, it appears necessary to find potential solutions of valosisation allowing to answer effectively these problems. the valorisation in civil engineering, of not immergeables sediments of ports of Dunkirk and Saint Louis, presents an alternative solution to the management of these materials. the works undertaken within the framework of this thesis are focused on the one hand, on the valorisation of Saint Louis sediment in road construction, and the other hand on the valorisation of Dunkirk sediment in concrete as well as artificials agregates. After physicochimical characterisation, mineralogical and mechanical, environmental impact of raw sediment of Saint Louis harbour and the potential use of these materials in road constuction are evaluated. the study of formulation of materials, for use in layer fondation, was based on an experimental method of determination of maximum compactness. The optimal granular mixtures fulfilling the terms of a use in a layer fondation are the evaluated through leaching tests. The concrete party concerns the formulation of the concretes containing Dunkerk sediment. After the characterisation of these materials, three concretes were the object of a durability study vis-a-vis the external sulphate attack associated with a not destructive characterisation in order to study the influence of incorporation of sediment on properties of concretes. The artificial aggregates party presents the feasibility study of aggregates with sediment, the granular plate and the big-bag technique are two making method used

The Effect of Granulation Time of the Pan Granulation on the Characteristics of the Aggregates Containing Dunkirk Sediments
AbstractThe wet granulation process presents complex interactions between equipment variables as well as material properties making the outcome of a granulation process hard to predict. A frequently encountered difficulty is the process control for optimal condition of the granulation. This requirement depends largely on the operator and the desired properties of the final product.In this study, before the fabrication of aggregates by the pan granulation by associating the sediments with a specific hydraulic binder, the ingredients were characterised. Then, the evolution of the aggregate size with the granulation time has been explored. Finally, the physical and mechanical properties of artificial aggregates formulated by the pan granulation were discussed. The results of this study show firstly, that the use of marine sediments dredged from Dunkirk harbour in France in the production of artificial aggregates is a flexible and positive approach. Secondly, that the granulation time is an important parameter that controls the granulation by wet granulation plate

Integration - Assimilation - acculturation - education.
Immigration which is a common phenomenon in the history of France sets a new problem to French society because of its significance, its fast moving pace and the circumstances found in civilization. The author does not pretend to propose a programme whose main lines could vary with time. He shows the intellectual or practical difficulties of "opening doors". This article which is not really indulgent remains optimistic. The immigrant and his foreign friend in spite of their differences think and feel they are "socii" ; the meaning of their social status will be clarified afterwards.L'immigration, phénomène presque coutumier dans l'histoire de France, pose par son ampleur, par son rythme précipité, par les circonstances civilisationnelles, un problème nouveau à la société française. L'auteur ne prétend pas proposer un programme dont les lignes pourraient varier avec le temps. Il montre les difficultés intellectuelles ou pratiques de certaines ouvertures. L'article, peu complaisant, demeure optimiste : l'immigré et son camarade étranger, malgré leurs divergences, se pensent et se sentent socii. Le sens de leur socialité s'éclairera dans la suite ...Ajerar Hassane. De l'intégration. Assimilation, acculturation, éducation.

This study aims at traching the critical path of the Moroccan Critic HASSANE EL MOUADDEN whose passion appearse in the relashionship between Psychoanalysis and Literature and the efforts he made in the field of Arabic and Maghreb Criticism that led him to read both ; the Sigmund Freud Psychoanalysis which focusses on the author ; and the Charle Morone Psychicological Criticism that focusses on the text, as well as all the Arabic and Maghreb writings in this field in where he deduced an immense weakness and uncapability of dealiing with texts . This study is based on how to reach EL MOUADDEN Psychicological project which was inspired by the Critic Jean Bellemin Noël textual unconscious concept through al tayib Salah novels , the novel and the textual analysis ; Arabic novel «Readings from Psychoanalysis prospectus» ; Psychological Reading in the story of prophet YUSUF «Brothrhood complex before OEDIPUS comple
ON THE PRESERVATION OF QUASI-MODULARITY
Let k be a eld of characteristic p ̸ = 0. In 1968, M.E. Sweedler revealed for the rst time, the usefulness of the concept of modularity. This notion, which play an important role especially for Galois theories of purely inseparable extensions, was used to characterize purely inseparable extensions of bounded exponent which were tensor products of simple extensions. A natural extension of the denition of modularity is to say that K/k is q-modular (quasi-modular) if K is modular up to nite extension. In subsequent papers M. Chellali and the author have studied various property of q-modular eld extensions, including the questions of q-modularity preservation in case [k : k p ] is nite. This paper grew out of an attempt to nd an analogue results concerning the preservation of q-modularity, without the hypothesis on k but with extra assumptions on K/k. In particular, we investigate existence conditions of lower (resp upper) quasi-modular closures for a given q-nite extension
L'œuvre littéraire et cinématographique de Sembène Ousmane face à ses lecteurs
La lecture est un acte complexe, qui a besoin, pour des raisons de pertinence d approche et surtout de continuité, de se référer aux circonstances générationnelles du texte, se mettre en relation avec l auteur de ce dernier, et de s en remettre à l intérêt constructeur qui est ici celui du sujet lisant. Tout comme l étude d un film éprouvant la nécessité, pour mieux comprendre son contenu et prolonger son destin, de se rapporter aux conditions de sa réalisation, à son producteur et l intérêt de son spectateur. L œuvre littéraire et cinématographique de Sembène Ousmane face à ses lecteurs devient ainsi l analyse de tous ces rapports, de l œuvre avec ses lecteurs, dont leurs prolongements, au-delà de l intérêt ludique et idéologique examiné par ce sujet, touchent à la fois le social, politique et le psychologique.The reading is a complex, which requires, for reasons of relevance and sometimes approach of continuity, to refer to the circumstances generational text, be in touch with the author of the latter, and it furnish to the manufacturer interest here is the reading matter. Like the study of a film challenging the need for a better understanding of its contents and prolong his destiny, relate to the conditions of its achievement, its producer and the interests of its audience. "The literary and cinematic Sembene Ousmane meet its readers" thus becomes the analysis of all these reports of the work with its readers, including its extension beyond the interest playful and ideological consideration by the topic, affect both the social, political and psychological.CERGY PONTOISE-BU Les Cerclades (951272104) / SudocSudocFranceF
Aneurysmal cyst of the thumb in young adults: about an exceptional case
The aneurysmal bone cyst is a benign, locally aggressive tumour. It affects children and young adults with a preference for the long bones and the vertebrae, rarely the hand. Involvement of the thumb is exceptional, the author reports an observation in a young 18-year-old patient, complaining of a painful swelling of the right thumb. The positive diagnosis is evoked on radiography, confirmed by the histology after surgical biopsy. Radical excision was opted for our patient, who, unlike conservative treatments, seems to avoid recurrence

Development Prospect of Smart Grid in Morocco
AbstractThe electrical power industry in Morocco is facing challenges involved with sustained growth of demand, added to environmental protection requirements. Smart Grid (SG) holds a great promise for a cleaner, more efficient power, healthier air and lower greenhouse gas emissions by adapting production to demand, reducing consumption and incorporating large amounts of distributed “green” generations at the consumers end. In this talk, SG and its principal functions are discussed, while SG is a continuum from systems of today towards smartness, the Moroccan electrical grid's study shows that the government has taken several initiatives to make some of the existing power grid functions smarter. At last, the basic studies needed for developing SG in Morocco are presented and several suggestions in various aspects are prospected
