Maurice Sand, un créateur fantastique méconnu : la transversalité, brisant d’une œuvre au 19e siècle

Sauf par des regards fugitifs et distraits sur son travail d’illustrateur et son théâtre de marionnettes, l’histoire culturelle et littéraire n’a en général retenu de Maurice Sand que son état de fils bien-aimé de la plus célèbre écrivaine du 19e siècle. Étudiée pour elle-même, son œuvre multidisciplinaire - qui allie peinture, dessin, illustration, théâtre, histoire de l’art, sciences naturelles - se propose pourtant avec cohérence, marque d’une création soutenue plutôt que du dilettantisme où son souvenir s’est incrusté. Maurice Sand apparaît alors comme un de ces individus situés aux interstices des récits majeurs de la littérature et des arts qui, bien qu’ayant figure de minores, amènent à des réflexions nuancées sur la constitution de ces récits. Explorer son cas permet ainsi de scruter de plus près les mécanismes de la méconnaissance qui a pu et peut encore affecter un créateur et une œuvre soumis aux arbitrages mémoriels. Discrets angles morts de l’histoire, certains de ces mécanismes jalonnent clairement son parcours et les aléas de sa trace posthume. D’une part le vaste corpus des études sur George Sand, notamment des écrits biographiques et autobiographiques, fait voir à l’œuvre le mode déformant de la constitution de la mémoire d’un être saisi à partir des positions d’autrui : son existence devient cliché, elle se réduit peu à peu au rôle d’adjuvant dans des débats, passés ou actuels, qui font l’impasse sur le cours autonome de sa carrière, voire de sa vie. D’autre part la mise au jour de son œuvre, enfin vue comme un ensemble, dévoile une cause encore plus déterminante de sa méconnaissance. Presque tous les travaux de Maurice Sand sont traversés par une ligne de fantastique, au surplus connotée par son intérêt pour les sciences liées à la métamorphose, de l’ethnogénie à l’entomologie. Réinvention constante du passé, sa démarche cognitive et créatrice ignore les frontières disciplinaires, son objet est hybride et composé. L’œuvre se constitue ainsi par transversalité, trait et trame irrecevables en un siècle qui n’y perçut que dispersion, mais paradoxalement marque supérieure de qualité dans le champ éclaté où se déploient les arts de notre temps.

Settlement Of Reinforced Sand In Foundations

The technique of reinforcing soil for foundation improvement is well established. This paper addresses the aspect of settlement of reinforced sand foundations, where the major part of the existing work deals with the aspect of bearing capacity. A detailed analysis is made paying individual attention to soil, reinforcement, and the interface between the two. A three-dimensional, nonlinear finite-element analysis is presented that uses a three-dimensional, nonlinear soil-reinforcement interface friction element, along with other threedimensional elements to model the system. The results of the analysis are compared with those from tests conducted in the laboratory and are found to be in good agreement. The studies lead to a better understanding of the behavior of the system at different stages of loading

Interpretation of the anisotropy of M MO radiation in slow I on Au collisions

A comparison between experimental and calculated spectral shape and energy dependence of the M MO x-ray anisotropy in heavy-ion collisions of I on Au is presented. The calculation is performed within the kinematic-dipole model of anisotropy using MO x-rays determined from SCF relativistic correlation diagrams.

Slow and Smooth: A Bayesian Theory for the Combination of Local Motion Signals in Human Vision

In order to estimate the motion of an object, the visual system needs to combine multiple local measurements, each of which carries some degree of ambiguity. We present a model of motion perception whereby measurements from different image regions are combined according to a Bayesian estimator --- the estimated motion maximizes the posterior probability assuming a prior favoring slow and smooth velocities. In reviewing a large number of previously published phenomena we find that the Bayesian estimator predicts a wide range of psychophysical results. This suggests that the seemingly complex set of illusions arise from a single computational strategy that is optimal under reasonable assumptions.

Las Jarretaderas, Nayarit, Mexico: a Social Interstice in Touristic Zona Metropolitana of Sun and Sand

The objective of the present article is to illustrate the social interstice (Las Jarretaderas) existing between the municipalities Bahía de Banderas, Nayarit and Puerto Vallarta, Jalisco. The researched community is an outstanding case-study providing an in-depth analysis of a number of social process mostly related to the chiapaneca migration. The text is divided into two sections. The first one deals with the urbanization process of the metropolitan area of Puerto Vallarta. The second and longer section defines the concept of social interstice and explains how the researched locality falls under under that previously-defined concept according to the processes analyzed.

So slow!

Caracol está dormido bajo una maceta del jardín, cuando de repente la maceta se mueve y el caracol siente el calor del sol en su concha. Caracol no puede permanecer al sol, así que cuando siente el calor de los rayos en su concha empieza un lento y largo viaje para encontrar alguna sombra fresca en el huerto del otro lado de la pared, ya que sólo tiene un corto periodo de tiempo antes de que el sol caliente lo seque. En el camino, se encuentra con un gato, una avispa, una mariposa y una araña, los cuales están muy dispuestos a demostrar cuánto más rápidos son que los caracoles.

Equatorial Kelvin waves as revealed by EOS Microwave Limb Sounder observations and European Centre for Medium-Range Weather Forecasts analyses: Evidence for slow Kelvin waves of zonal wave number 3

[1] Temperature and ozone observations from the Microwave Limb Sounder (MLS) on the EOS Aura satellite are used to study equatorial wave activity in the autumn of 2005. In contrast to previous observations for the same season in other years, the temperature anomalies in the middle and lower tropical stratosphere are found to be characterized by a strong wave-like eastward progression with zonal wave number equal to 3. Extended empirical orthogonal function (EOF) analysis reveals that the wave 3 components detected in the temperature anomalies correspond to a slow Kelvin wave with a period of 8 days and a phase speed of 19 m/s. Fluctuations associated with this Kelvin wave mode are also apparent in ozone profiles. Moreover, as expected by linear theory, the ozone fluctuations observed in the lower stratosphere are in phase with the temperature perturbations, and peak around 20–30 hPa where the mean ozone mixing ratios have the steepest vertical gradient. A search for other Kelvin wave modes has also been made using both the MLS observations and the analyses from one experiment where MLS ozone profiles are assimilated into the European Centre for Medium-Range Weather Forecasts (ECMWF) data assimilation system via a 6-hourly 3D var scheme. Our results show that the characteristics of the wave activity detected in the ECMWF temperature and ozone analyses are in good agreement with MLS data.

Physico-chemical controls on phosphorus cycling in two lowland streams. Part 2 - The sediment phase

This article investigates the temporal and spatial controls on sediment-phosphorus (P) dynamics in two contrasting sub-catchments of the River Kennet, England. Suspended sediment (collected under representative flow conditions) and size-fractionated bedload (collected weekly for one year) from the Rivers Lambourn and Enborne was analysed for a range of physico-chemical determinands. Total P concentrations were highest in the most mobile fractions of sediment: suspended sediment, fine silt and clay and organic matter (mean concentrations of 1758, 1548 and 1440 mug P g(-1) dry sediment, respectively). Correlation analysis showed significant relationships between total P and total iron (n = 110), total manganese (n = 110), organic matter (n = 110) and specific surface area (n = 28) in the Lambourn (r(2) 0.71, 0.68, 0.62 and 0.52, respectively) and between total P and total iron (n = 110), total manganese (n = 110) and organic matter (n = 110) in the Enborne (r(2) 0.74, 0.85 and 0.68, respectively). These data highlight the importance of metal oxyhydroxide adsorption of P on fine particulates and organic matter. However, high total P concentrations in the granule gravel and coarse sand size fraction during the summer period (mean concentration 228 mug P g(-1) dry sediment) also highlight the role of calcite co-precipitation on P dynamics in the Lambourn. P to cation ratios in Lambourn sediment indicated that fine silt and clay and granule gravel and coarse sand size fractions were potential sources of P release to the water column during specific periods of the summer and autumn. In the Enborne, however, only the granule gravel and coarse sand size fraction had high ratios and a slow, constant release of P was observed. In addition, scanning electron microscopy work confirmed the association of P with calcite in the Lambourn and P with iron on clay particles in the Enborne. The study highlighted the importance of the chemical and physical properties of the sediment in influencing the mechanisms controlling P storage and release within river channels.
