The increasing demand for renewable energy may lead to the conversion of millions of hectares into bioenergy plantations with a possible substantial transitory carbon (C) loss. In this study we report on the greenhouse gas fluxes (CO2, CH4, and N2O) measured using eddy covariance of a short-rotation bioenergy poplar plantation converted from agricultural fields. During the first six months after the establishment of the plantation (June–December 2010) there were substantial CO2, CH4, and N2O emissions (a total of 5.36 ± 0.52 Mg CO2eq ha−1 in terms of CO2 equivalents). Nitrous oxide loss mostly occurred during a week-long peak emission after an unusually large rainfall. This week-long N2O emission represented 52% of the entire N2O loss during one and an half years of measurements. As most of the N2O loss occurred in just this week-long period, accurately capturing these emission events are critical to accurate estimates of the GHG balance of bioenergy. While initial establishment (June–December 2010) of the plantation resulted in a net CO2 loss into the atmosphere (2.76 ± 0.16 Mg CO2eq ha−1), in the second year (2011) there was substantial net CO2 uptake (−3.51 ± 0.56 Mg CO2eq ha−1). During the entire measurement period, CH4 was a source to the atmosphere (0.63 ± 0.05 Mg CO2eq ha−1 in 2010, and 0.49 ± 0.05 Mg CO2eq ha−1 in 2011), and was controlled by water table depth. Importantly, over the entire measurement period, the sum of the CH4 and N2O losses was much higher (3.51 ± 0.52 Mg CO2eq ha−1) than the net CO2 uptake (−0.76 ± 0.58 Mg CO2eq ha−1). As water vailability was an important control on the GHG emission of the plantation, expected climate change and altered rainfall pattern could increase the negative environmental impacts of bioenergy.

Polymer concretes appear as useful materials for manufacturing precast elements as well as for repair and protection of building structures. In both cases, there is a need for quality control and diagnosis during service life as well. Therefore the development of nondestructive assessment methods is an important issue. Ultrasonic methods are among the most common nondestructive techniques used in material science and industry. The aim of the paper was to analyze the usability of ultrasonic methods for assessing properties of polymer concretes modified with fly ashes. In the paper the effects of substitution of microfiller with fly ash in polyester and vinyl ester concretes on ultrasonic wave propagation are presented. Compositions of tested fly ash polymer concretes were determined using material optimization approach. Propagation of ultrasonic wave was characterized using wave velocity and a frequency spectrum characteristic. As a result, regression functions for ultrasonic evaluation of fly ash polymer concrete are proposed. Those functions can be used to develop reference curves for calibration procedures for this kind of composites. [less ▲]

L’année 2012 marque un double anniversaire: 40 ans d’existence du Front National (FN) français, 30 ans d’existence médiatique. Cette communication tente de montrer en quoi la communication du FN paraît particulièrement bien adaptée aux logiques médiatiques. Il s’agit de réévaluer le « contrat de mariage » FN/médias à la lumière des évolutions récentes qui ont affecté leurs relations depuis que Marine Le Pen a repris le flambeau, de manière à éclairer, plus généralement, les conditions médiatiques d’existence des partis dits « populistes ». J’évoquerai les mutations récentes de la communication du FN, sur le plan des discours et des relations avec les journalistes, avant d’aborder l’évolution concomitante du traitement médiatique de Marine Le Pen. À partir de là sera posée la question de la diffusion des idées frontistes dans l’espace médiatique, envisagée comme le produit d’une interaction entre les instances politique, médiatique et citoyenne – l’ « opinion publique » saisie par les sondages. Je tâcherai alors de faire le point sur les différentes logiques médiatiques qui tendent à valoriser le parti, avant de conclure par quelques considérations sur les défis que représentent pour les journalistes les métamorphoses actuelles du FN.

In this article, we describe the development of a simple laboratory test for the effective screening of foam control agents on a selected fermentation system, the mass production of Yarrowia lipolytica. Aeration testing is based on sparging air in the foaming medium allowing partial reproduction of the gas-liquid hydrodynamic encountered in bioreactors. "Dynamic sparge test," for which measurements are made during foam formation, was used to compare the capacity of three antifoams, based on different technologies, to control the foam produced in the fermentation broth. The selected foam control agents were: (1) an organic antifoam (TEGO AFKS911), (2) a silicone-based emulsion containing in situ treated silica (DC-1520) and (3) a silicone/ organic blend silica-free formulation. The testing results demonstrated dramatic differences among them and showed that the capacity of TEGO AFKS911 and DC-1520 to control the foam generated in the fermentation broth decreases as a function of fermentation time. This occurred to a much lesser extent for the silicone/ organic blend formulation. These results were correlated with the change of the foam nature and the increase of foam stability of the fermentation broth with culture time. The increase in protein content as a function of growth time was correlated with an increase in foam stability and antifoam consumption. A "synthetic fermentation broth" was also developed, by adding both proteins and microorganism to the culture medium. This allowed us to mimic the fermentation broth, shown by the similar antifoams behaviour, and is therefore a simple methodology useful for the selection of appropriate antifoams. [less ▲]

We report an experimental study of aqueous foam imbibition in microgravity with strict mass conservation. The foam is in a Hele-Shaw cell. The bubble edge width l is measured by image analysis. The penetration of the liquid in the foam, the foam imbibition, the foam inflation, and the rigidity loss are shown all to obey strict diffusion processes. The motion of bubbles needed for the foam inflation is a slow two-dimensional process with respect to the one-dimensional capillary rise of liquid. The foam is found to imbibes faster than it inflates. [less ▲]
