Most of the IPCC-AR4 Atmospheric Global Circulation Models (AGCM) predict an increase of the Antarctic Surface Mass Balance (SMB) during the 21st century, driven by an increase of snow falls, which would mitigate the sea level rise. Much of the SMB change is expected to happen in the Antarctic coastal area, which concentrates the major part of the snow falls. This area is also were we find complex processes of precipitation, sublimation, melt and redistribution by the wind. High-resolution modeling (5 to 10 km) is necessary to accurately capture the effects of the fine topography on the atmospheric variables but limitations in computing resources prevent such resolution at the scale of Antarctica in full climate models. We present here a downscaling method yielding to a 10-km resolution of the SMB for the 21st century, from ~60-km resolution LMDZ4 AGCM outputs. We compute orographic precipitation induced by the finer topography, as well as the boundary layer processes leading to melt and sublimation. It shows a clear improvement of the SMB distribution in coastal regions with consequences on the grounded ice sheet SMB estimation. [less ▲]

L'année 2004 fut celle de l'anniversaire du deuxième centenaire de la mort d'Emmanuel Kant. Les deux Centres de recherche des Universités de Lecce et de Paris-Sorbonne qui collaborent habituellement dans le domaine des études cartésiennes et, plus généralement, de l'histoire de la philosophie moderne, ont à cette occasion associé leurs efforts pour rendre un hommage commun au philosophe allemand, tout en demeurant dans leur domaine privilégié d'investigation. Ce livre contient les travaux issus des deux rencontres internationales qui en ont résulté. Le titre choisi peut dérouter : sa correction grammaticale comme son sens ne vont pas de soi. - De quels noms propres s'agit-il ici ? Evidemment pas de ceux des individus empiriques, qui s'ignoraient, mais de ceux qui désignent, matériellement, deux corpus de textes. Leur confrontation pourrait faire apparaître un complexe idéal de questions, de concepts et de thèses dans ce qu'on appellera, suivant toute l'indétermination des termes, un système de pensée. Autrement dit, l'un et l'autre se répondraient, à un siècle et demi d'écart, sans discussion directe, mais dans la sauvegarde des mêmes interrogations. Quel point de concours réunirait, sans confusion mais sans métaphore, le corpus qu'identifie la marque " Descartes " et celui dont l'étiquette porte le nom de " Kant " ? Il ne s'agit pas seulement d'étudier des questions communes, d'éventuelles polémiques, voire d'hypothétiques influences entre Descartes et Kant. Il est plutôt question, finalement, de reconnaître dans quelle mesure Kant renouvelle le moment cartésien, en sorte que, lorsque Kant pense, Descartes s'avance encore, caché. Caché et déguisé en Kant - Descartes en Kant, comme le portrait de l'artiste en jeune homme. [less ▲]

On a pris l’habitude de voir en l’analyse un instrument logique de décomposition et de clarification des concepts, confirmant du même coup l’évaluation critique qu’en a donnée Kant : l’analyse est un procédé stérile qui ne contribue en rien à l’expansion et au renouvellement des connaissances. Soulignant la cohérence de ses emplois historiques, le présent ouvrage cherche au contraire à rétablir l’analyse en sa fonction inventive : de l’Antiquité au XVIIe siècle, la méthode analytique constitue, en effet, une solution aux insuffisances de la déduction logique ; s’appuyant sur la construction et le déchiffrement des figures, elle offre une voie à la fois détournée et probante pour la résolution des problèmes. Descartes est l’héritier de cette tradition, mais il est aussi, à maints égards, l’inventeur de la conception moderne de l’analyse. Au-delà des perspectives ouvertes par la réhabilitation de l’analyse des géomètres dans le strict domaine mathématique, c’est comme un type original de construction intellectuelle que l’analyse s’impose sous sa plume, et cela jusque dans la philosophie première. Les Méditations métaphysiques attestent en effet que Descartes, le premier, a voulu faire de l’analyse la voie privilégiée de la connaissance de soi en conférant à celle-ci une structure méthodique qui est restée largement méconnue de ses interprètes. Accomplissement heuristique de « l’ordre des raisons » mais aussi aventure temporelle inscrite dans la durée féconde de la méditation, l’analyse se révèle alors l’instrument d’une raison radicalement créatrice.

In “Poema(s) da Cabra”, João Cabral de Melo Neto takes the figure of the goat, both "nordestino" (originating and tied to the Northeast of Brazil) and Mediterranean as his object. Qualifications, abilities, potencies are continuously added to the goat. However, in adding so much, what could have been a symbol – some material element that refers to an idea – actually becomes pure quality. The goat goes from being a study object to the intrinsic value of the nordestino. In order to build this path, João Cabral will use some of his well-known poetic resources, such as tone, form, rhyme and vocabulary. These components are analyzed alongside other not so frequently mentioned ones, so as to show the way by which these are intricately built onto the structure of the text, but also the way by which they operate to build the suggested effect: that of un object that is transformed in pure value.

Since the last 5 years, a specific hemorrhagic syndrome of unknown etiology was described in young calves. This disease has a low incidence but a very high mortality rate. No etiology has been found yet, though many labs have already gathered lots of cases around Europe. For example, more than 200 cases in 170 farms in Germany, 60 cases in 40 farms were described in Gent’s veterinary faculty in Belgium. In France and in the United Kingdom, several cases have been recorded yet, in multiple different locations. As far as we know, the disease concern young calves aging between 10 and 30 days, from different breeds. Most calves present a purpura on multiple sites on skin, gums, eye sclera and ears. Hematology indicates severe anemia, thrombocytopenia, neutropenia with or without leukopenia. Necropsy indicates multiple hemorrhages in serous membranes on every abdominal viscera. Alfort’s veterinary faculty has described acute necrotizing hepatitis on one case in France. Those calves are BVDV and BTV negative both on antigen tests. In Liege’s veterinary faculty one live case was examined, from a modern farm with 160 calvings, and less than 5% of calf mortality per year. The farm had 3 hemorrhagic fatal cases during July 2009, of very quick evolution. From those, 2 were autopsied and diagnosed BVDV negative. The 20 days old calf had hyperthermia in the morning, received oxytetracycline in the farm and began bleeding at noon. As many of the described cases, the calf presented mild depression with hyperthermia and tachypnoea. Skin and ear purpura, gum hematoma, melena, hematuria and hemoglobinuria were noticed. Hematology revealed a severe anemia with decreased hematocrite due to a profound thrombocytopenia (4.79*109/l). Leukocytes formula also shown neutropenia (0.10*109/l) and a monocytosis (1.32*109/l). It resulted in a mild leukopenia (3.59*109/l). We also noticed hypogammaglobulinemia (2.92 g/l and 6.8% of total protein). This calf received an immune-suppressive treatment with a high dose of dexamethasone (0.64mg/kg), and a cover antimicrobial therapy (Enrofloxacine). A good evolution of the symptoms on day 2 was observed. Leukocyte formula had a normal answer to dexamethasone concerning the lymphocytes and neutrophils population. On day 6, blood formula was already stabilized, with increasing hematocrite from 12% on day 3 to 15%. Thrombocytes count has also increased to 58.20*109/l; leukocytes count was also back to normal with normal formula. Flow cytometric measures on the lymphocytes subpopulations indicated a subnormal Gamma-Delta and Natural Killer population, and a high number of apoptotic cells 12 hours after sampling. This syndrome can be linked to idiopathic thrombocytopenia in human newborn both regarding symptomatology and treatment answer. Though this data helps in the understanding of this pathology, it concerns only one animal and needs to be confirmed through further experiment on live cases. [less ▲]

Due to its small size, its short developmental cycle and its close phylogenetic relationship with the Triticeae tribe, Brachypodium distachyon (L.) Beauv. has been proposed as a model species for temperate cereals. In this context, this work aims to describe and model root and shoot growth and development of B. distachyon (Bd21-1) grown under controlled environmental conditions [22°C, 65% RH, 20h light, 95 µmol.m-2.s-1 (PAR, LED lighting)]. For this purpose, vernalized caryopses were sown in a substrate consisting of vermiculite and compost (80/20, v/v). Growth and development of the above and belowground parts were monitored for 70 days. Dry and fresh masses of plant organs were measured every seven days from sowing. Biomasses of adventitious and seminal roots were measured separately. The number of spikelets on the main stem and on tillers was also counted on plants aged of 70 days. The modelling of root and shoot growth was achieved by calibrating sigmoidal growth models to the mean biomass values measured at each day of analysis. For each plant organ, the growth model selected was the one with the lowest residual variance. Finally, developmental stages identified for B. distachyon were compared with those defined for cereal crops by Zadoks et al. (1974). Maximum rates of fresh and dry shoot biomass production were 29,5 and 14,2 mg.day-1 respectively. Based on modelling, these values seem to be reached 49 and 72 days after sowing. Results also show that the fresh mass of adventitious roots at day 42 is significantly higher than that of seminal roots. Maximum rates of fresh and dry root biomass production were 6,9 and 0,8 mg.day-1 respectively, and were reached after 37 and 43 days. [less ▲]

We consider quasi-stationary scattering of interacting bosonic matter waves in one-dimensional waveguides, as they arise in guided atom lasers. We show how the truncated Wigner (tW) method, which corresponds to the semiclassical description of the bosonic many-body system on the level of the diagonal approximation, can be utilized in order to describe such many-body bosonic scattering processes. Special emphasis is put on the discretization of space at the exact quantum level, in order to properly implement the semiclassical approximation and the tW method, as well as on the discussion of the results to be obtained in the continuous limit.
