Reactions of n,n-dibromobenzenesulfonamide with alcohols and mercaptans, 1971
No full textN,N-Dibromobenzenesulfonamide reacts with primary alcohols in a 1:2 molar ratio to yield the esters of the alcohols. The reaction is believed to proceed via a free radical mechanism to generate the reac-tive acylbromide species which then reacts with another mole of the alcohol to yield the ester as the final product. Benzyl alcohol and short chain primary alcohols give the corresponding aldehydes as side reactions. NNDBS reacts with secondary alcohols to give ketones and alpha bromoketones. No reaction takes place with tertiary alcohols. N,N-Dibromobenzenesulfonamide reacts with primary, secondary and tertiary mercaptans to yield the disulfide of the mercaptans in each case. When molecular bromine was used as the brominating agent, the alcohols did not react but the corresponding disulfide was obtained from each mercaptan

Quatre lettres inédites d'Ange Goudar au marquis de Sade
No full textAnge Goudar : Four unpublished letters to the Marquis de Sade, presented by Maurice Lever.
Sade met Pierre-Ange Goudar, writer and adventurer, in 1775 during his flight to Italy after the "little girls" affair. An exchange of letters followed ; four of them, from the Sade family archives, are published here. Goudar expresses his opinions of Rome, Naples and Florence, his reflections on Cardinal Bernis and the Count of Saint-Germain, and speaks about his wife Sarah and his own writings. These unpublished pages reveal a hitherto totally unknown literary friendship between the author of Justine and another libertine called Goudar.Lever Maurice.

Maurice Le Lannou et la Bretagne / Maurice Le Lannou and the region of Brittany
No full textMaurice Le Lannou, a geographer originating from Brittany, also studied amongst other things, the geography of this region. His geographical vision of Brittany was by his origins and by his conception of geography. The development and destiny of Brittany interested him until the end of his days. He always remained faithful to his conception of geography, although Brittany was being radically transformed. It is thus necessary to show that after an initial period of complicity between the author and his region, this was followed by of confrontation.Maurice Le Lannou, géographe breton, fut aussi, entre autres orientations, géographe de la Bretagne. Sa vision géographique de la Bretagne fut influencée à la fois par sa "bretonnité", et par sa conception de la géographie. Le devenir et le destin de la Bretagne le préoccupèrent jusqu'à la fin. Il resta toujours fidèle à sa conception de la géographie alors que la Bretagne se transformait radicalement. D'où, entre l'auteur et son terrain, après une période de véritable "connivence", une période de confrontation qu'il importe d'expliciterFlatrès Pierre, Flatrès Huguette.

From flesh to fiction : the visible and the invisible in the work of Maurice Merleau-Ponty, Eudora Welty and Elizabeth Bowen.
No full textPhDOur ways of thinking modernism and its legacy are imprinted with the pattern of an
opposition, a struggle between two sets of extremes: objective and subjective; form
and feeling; mechanistic and organic; mind and body; knowing and being; self and
world; aesthetic and historical. The three writers whose work I explore in this thesis
challenge prevailing notions of this oppositional discourse. Entering the scene of
modernism late in its history, Elizabeth Bowen, Eudora Welty and Maurice Merleau-
Ponty develop a new kind of vision that makes us rethink the relationships between
perceiver and perceived, between mind, body and world. All three writers undertake a
fundamental reorganisation of the relationships between internal consciousness and
external things through the narration of a perception that is outside the limits of
discrete sensations or causal relationships. Physical things are neither pure objecthood
nor merely external triggers for the ramblings of a solipsistic consciousness, rather
they infringe on a consciousness whose own edges are indistinct. This writing
establishes an interdependent and interlocutory relationship between subject and
world, which become not opposite ends of a perceptual scale, but aspects of a common
flesh. The intimate connection to the world is both comforting and threatening, both
reinforcing subjectivity and de-centring it.
The re-ordering of the connections between self and world leads to a reassessment of
collective identity and historical agency, as well as impacting upon approaches to
modes of representation. In trying to express the pre-linguistic experience of embodied
consciousness, this writing looks to models of mute expression found in visual images.
Exploring how the invisible aspects of experience emerge within the visible realm, the
writing takes on an often hallucinatory or uncanny character. Charting the passage
from being to doing, from perception to creation, from the style of the flesh to the style
of fiction, Merleau-Ponty, Welty and Bowen dissolve received boundaries and
distinctions at every level
Éboulis et glaciers rocheux(Talus and rock-glaciers)
No full textThe author studies chrolonogic and morphogenic relations between talus screes or protalus accumulations and rock glaciers, together with the paleoclimatic and paleomorphologic significance of the environment of inherited rock glaciers.On examine les relations spatiales, temporelles et génétiques entre les éboulis ou formations de pente à blocailles structurées et les glaciers rocheux, ainsi que la signification paléoclimatique et paléomorphologique de l'environnement des glaciers rocheux hérités.Jorda Maurice.

Le faux échappement de Villard de Honnecourt
No full textSUMMARY. — A drawing of Villard de Honnecourt (13th cent.) is generally interpreted as the oldest picture representing a clockwork escapement. After making experiments, the author establishes that this is a misinterpretation due to a mistake in the drawing by Villard.RESUME. — Un dessin de Villard de Honnecourt (XIIIe siècle) est généralement interprété comme la plus ancienne représentation d'un échappement d'horlogerie. Après en avoir fait l'expérimentation, l'auteur montre que cette interprétation est erronée et tient à une erreur dans le dessin de Villard.Daumas Maurice.

Maurice Daumas reader of Lucien Febvre
No full textDeux registres d’action se croisent sans se recouper complètement dans la pensée de Maurice Daumas, directeur scientifique et auteur de l’Histoire générale des techniques, parue aux Presses universitaires de France de 1962 à 1979, déjà auteur d’une Histoire de la science parue chez Gallimard, dans l’Encyclopédie de la Pléiade, en 1957. D’une part, le fait que, pour Daumas, l’invention technique « est le résultat d’une expérience collective sans cesse accumulée », ce qui explique la simultanéité des inventions. Ce constat pourrait être mis en parallèle avec L’apparition du livre, publié par Lucien Febvre et Henri-Jean Martin en 1958. D’autre part, les conditions de production d’une histoire des techniques sont indissociables d’une collaboration entre différents types de contributeurs, comme le montre le numéro spécial « Les techniques, l’histoire et la vie » publié dans les Annales d’histoire économique et sociale en 1935. L’article interroge les renvois entre ces différentes publications et les concepts à l’œuvre sur la technique entre 1935 et 1979, sans oublier le fait que Febvre et Daumas sont également des entrepreneurs d’édition scientifique, pour qui la réflexion sur la technique ne se dissocie pas d’une certaine expérience pratique.Two concepts cross themselves without completely overlapping in Maurice Daumas’ work, publisher and author of Histoire de la science (Gallimard, 1957) and Histoire générale des techniques (PUF, 1962-1979). On the one hand, the technological invention “is the result of a collective experience constantly accumulating,” fact which could explain the simultaneity of inventions (cf. L’apparition du livre, Lucien Febvre & Henri-Jean Martin, 1958). On the other hand, the conditions for history of technology are indissociable from collaborations between contributors of different academic backgrounds (cf. Annales d’histoire économique et sociale, “Les techniques, l’histoire et la vie”, n° 36, Nov. 30th 1935). This article aims to investigate links between the various concepts concerning technology (technique) in those publications that came out between 1935 and 1979, while taking into consideration that Febvre and Daumas are also publishers: their reflections on technology could not be separated from a certain practice
Le livre invisible : trois émissions de la télévision française sur le livre
No full textThe author presents a semiotic analysis of three French television programs on recent book publications. These programs are described and then interpreted from two perspectives : how does television «handle » the book and how does television succeed in dissimulating its mediating role in creating «reality ».L'auteur décrit et interprète trois émissions de la télévision française qui traitent du livre. De nature sémiotique, son analyse comprend deux plans d'observations : le traitement du livre parla télévision et la télévision comme un lieu et un moment de dissimulation de sa médiation.El autor describe e interpreta tres emisiones de la televisión fran¬ cesa concernientes a libros. De carácter semiótico, su análisis comprende dos aspectos observables : La manera como son tratados los libros por parte de la televisión y la televisión misma como lugar y momento de disimulación de su mediación.Mouillaud Maurice.

Théâtre et esprit public : les représentations du Mariage de Figaro à Paris (1784-1797)
No full textAlthough Beaumarchais played a considerable role in the war of American independence and in the diffusion of its principles in France, in particular through the Courrier de l'Europe which published the first French translation of the United States' Declaration of Independence on August 20th 1776, the 'Voltigeur des Lumières3 (Enlightenment Acrobat) hardly used the concept of public spirit. However, an analysis of performances of the Mariage de Figaro in Paris between 1784 and 1797 makes it possible to apprehend the evolution of the concept during the Revolution from two points of view. Firstly that of the theatre as a space in which an authority emanating from an assembled audience can be exercised. Secondly, that of the resistance of the assembled audience's spirit which is unlike public opinion and the written press that tend to imply an audience which is scattered or confined to private spaces, with regard to its formation, direction or manipulation. The specificity of this cultural practise, based on the three poles of the actor, the audience and the author, turns the audience and actors into co-authors and the playwright himself can help to modify the show's meaning through performance by adding or suppressing parts. A play's meaning is elaborated by the author but also by the actors and the audience who interact in a given socio-political context.Nadeau Maurice.
