Concentración y centralización del capital agrario en la región pampeana : El caso de los grandes pooles de siembra

El objetivo de este trabajo es juzgar las potencialidades del proceso de concentración del capital agrario a partir del caso de los llamados "grandes pooles de siembra". Para tal fin, se realiza un análisis de los proyectos de inversión y de producción de los pooles de siembra constituidos como Fondos Comunes Cerrados de Inversión y como Fideicomisos Financieros. Asimismo, se realiza un estudio en profundidad del caso del principal administrador de grandes pooles de siembra, la empresa Cazenave y Asociados. Se concluye que la producción agraria pampeana continúa siendo un espacio hostil para la acumulación de los capitales más concentrados de la economía.

(Table 1) Water storage changes of the 33 world's largest river basins between 2002-2009

Global change in land water storage and its effect on sea level is estimated over a 7-year time span (August 2002 to July 2009) using space gravimetry data from GRACE. The 33 World largest river basins are considered. We focus on the year-to-year variability and construct a total land water storage time series that we further express in equivalent sea level time series. The short-term trend in total water storage adjusted over this 7-year time span is positive and amounts to 80.6 ± 15.7 km**3/yr (net water storage excess). Most of the positive contribution arises from the Amazon and Siberian basins (Lena and Yenisei), followed by the Zambezi, Orinoco and Ob basins. The largest negative contributions (water deficit) come from the Mississippi, Ganges, Brahmaputra, Aral, Euphrates, Indus and Parana. Expressed in terms of equivalent sea level, total water volume change over 2002-2009 leads to a small negative contribution to sea level of -0.22 ± 0.05 mm/yr. The time series for each basin clearly show that year-to-year variability dominates so that the value estimated in this study cannot be considered as representative of a long-term trend. We also compare the interannual variability of total land water storage (removing the mean trend over the studied time span) with interannual variability in sea level (corrected for thermal expansion). A correlation of ~0.6 is found. Phasing, in particular, is correct. Thus, at least part of the interannual variability of the global mean sea level can be attributed to land water storage fluctuations.

Steric sea-level variations inferred from combined Topex/Poseidon altimetry and GRACE gravimetry

In this study, we propose to estimate the steric sea-level variations over a < 2-year period (April 2002 through December 2003) by combining global mean sea level (GMSL) based on Topex/ Poseidon (T/P) altimetry with time-variable geoid averaged over the oceans, as observed by the GRACE (Gravity Recovery and Climate Experiment) satellite. In effect, altimetry-derived GMSL changes results from two contributions: Steric (thermal plus salinity) effects due to sea water density change and ocean mass change due to water exchange with atmosphere and continents. On the other hand, GRACE data over the oceans provide the ocean mass change component only. The paper first discusses the corrections to apply to the GRACE data. Then the steric contribution to the GMSL is estimated using GRACE and T/P data. Comparison with available thermal expansion based on in situ hydrographic data is performed.

Le mandat d’eurodéputé est conçu différemment dans chaque état membre. Cet article teste la validité des cultures politiques inclusive et exclusive, créées pour l’analyse des sélections des candidats français et suédois et leur conception du mandat européen. Leur sélection demeure un monopole partisan national où l’adhésion à un parti et la professionnalisation politique priment. La distinction apparait dans le degré d’ouverture de la sélection et la conception de la fonction d’eurodéputé et du Parlement européen. Les conclusions valident l’approche créée, montrant un déplacement du curseur le long des continuums formés par les cultures inclusive et exclusive. La France, «exclusive», reste centrée sur Paris et des élections ayant des conséquences sur le pouvoir exécutif. La Suède est plus inclusive tant dans les profils des candidats que dans les processus qui les intègrent aux listes et dans la façon de concevoir le rôle des MEP et du Parlement européen. Cet article se fonde sur un mémoire de Master: E. Cazenave, Eurodéputé: «Seconde chance» ou «Tremplin»?

Multifaceted Role of Heme during Severe Plasmodium falciparum Infections in India

Several immunomodulatory factors are involved in malaria pathogenesis. Among them, heme has been shown to play a role in the pathophysiology of severe malaria in rodents, but its role in human severe malaria remains unclear. Circulating levels of total heme and its main scavenger, hemopexin, along with cytokine/chemokine levels and biological parameters, including hemoglobin and creatinine levels, as well as transaminase activities, were measured in the plasma of 237 Plasmodium falciparum-infected patients living in the state of Odisha, India, where malaria is endemic. All patients were categorized into well-defined groups of mild malaria, cerebral malaria (CM), or severe noncerebral malaria, which included acute renal failure (ARF) and hepatopathy. Our results show a significant increase in total plasma heme levels with malaria severity, especially for CM and malarial ARF. Spearman rank correlation and canonical correlation analyses have shown a correlation between total heme, hemopexin, interleukin-10, tumor necrosis factor alpha, gamma interferon-induced protein 10 (IP-10), and monocyte chemotactic protein 1 (MCP-1) levels. In addition, canonical correlations revealed that heme, along with IP-10, was associated with the CM pathophysiology, whereas both IP-10 and MCP-1 together with heme discriminated ARF. Altogether, our data indicate that heme, in association with cytokines and chemokines, is involved in the pathophysiology of both CM and ARF but through different mechanisms.
