    L'article presenta una visió panoràmica de l'intent no reeixit de modernització de la Universitat de Barcelona durant el breu període d'autonomia universitària. Aquest procés entrebancat de reforma d'una de les institucions més tradicionalment conservadores, com era la universitat, va ser menat principalment per una generació de prestigiosos intel·lectuals universitaris. Interessa, amb tot, no tant destacar les fugisseres realitzacions de l'autonomia universitària barcelonina tal vegada mitificades per la memòria dels seus protagonistes principals com mirar de resseguir els diversos fronts de resistència que s'hi oposaren, en els quals van confluir dinàmiques internes inercials, discontinuïtats transformadores i confrontacions polítiques fortament ideologitzades.This article provides an overview of the unsuccessful attempt at modernising Barcelona University during the brief period of university independence.

    A new species of Allophaiom,i.r. A. chalinei, is described from the Lower Pleistocene of the Victoria cave (Murcia. Spain). This species is characterized by his great si~e, with confluent T 4 and T 5 and it has been also fouiid at the lower levels of Atapuerca (Burgos) and Venta Micena (Granada)

    Interstitial pulmonary fibrosis with and without associated collagen vascular diseases: results of a two year follow up

    Background: Interstitial pulmonary fibrosis is a disease with a highly variable clinical course. To ascertain if an inadequate selection of patients might explain part of this variability, two different groups of patients with interstitial pulmonary fibrosis, those with the 'lone' form of the disease (LIPF) and those with associated collagen vascular disorders (AIPF), were studied separately. Methods: Twenty consecutive patients (nine with LIPF and 11 with AIPF) were included. Their clinical and radiographic findings and results of pulmonary function tests, gallium-67 lung scanning, and cellular analysis of bronchoalveolar lavage fluid were compared at diagnosis. Moreover, the evolution of LIPF and AIPF was contrasted after a follow up of two years, both groups having received a similar treatment regimen of corticosteroids. Results: At enrollment, patients with LIPF and AIPF were of similar age, and had similar symptoms and derangement of lung function, but patients with LIPF presented with finger clubbing, more obvious radiographic abnormalities, and a greater percentage of eosinophils in bronchoalveolar lavage fluid. Two years later, patients with LIPF had significantly decreased FVC, FEV1, TLC, TLCO, and PaO2. By contrast, lung function remained unaltered in patients with AIPF. Similarly, when the percentage change from entry to the study was compared, patients with LIPF showed a significant decrease in FVC, FEV1, and PaO2. Conclusions: Unlike the patients with AIPF, those with LIPF showed a deterioration in lung function and developed further restrictive impairment and poorer gas exchange. This has implications in their clinical management

    Groupoïdes riemanniens

    We propose a definition of a riemannian groupoid, and we show that the Stefan foliation that it induces is a riemannian (singular) foliation. We also prove that the homotopy groupoid of a riemannian (regular) foliation is a riemannian groupoid

    Ecosystem photosynthesis in land-surface models: a first-principles approach

    Get PDF
    Vegetation regulates land-atmosphere water and energy exchanges and is an essential component of land-surface models (LSMs). However, LSMs have been handicapped by assumptions that equate acclimated photosynthetic responses to environment with fast responses observable in the laboratory. These time scales can be distinguished by including specific representations of acclimation, but at the cost of further increasing parameter requirements. Here we develop an alternative approach based on optimality principles that predict the acclimation of carboxylation and electron-transport capacities, and a variable controlling the response of leaf-level carbon dioxide drawdown to vapour pressure deficit (VPD), to variations in growth conditions on a weekly to monthly time scale. In the “P model”, an optimality-based light-use efficiency model for gross primary production (GPP) on this time scale, these acclimated responses are implicit. Here they are made explicit, allowing fast and slow response time-scales to be separated and GPP to be simulated at sub-daily timesteps. The resulting model mimics diurnal cycles of GPP recorded by eddy-covariance flux towers in a temperate grassland and boreal, temperate and tropical forests, with no parameter changes between biomes. Best performance is achieved when biochemical capacities are adjusted to match recent midday conditions. This model suggests a simple and parameter-sparse method to include both instantaneous and acclimated responses within an LSM framework, with many potential applications in weather, climate and carbon - cycle modelling
