We investigate the dynamic response of a vortex lattice in nanostructured superconducting Pb films by means of ac-magnetization measurements. We compare the flux pinning properties of superconducting Pb films with arrays of fully perforated holes (antidots) and partially drilled holes (blind holes). Our results show that an array of blind holes, characterized by a thin superconducting bottom layer, gives rise to a less efficient pinning potential than an array of antidots. On top of that, a lower number of flux quanta trapped per pinning site (the saturation number), is observed for the blind hole array. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

Livret-guide des journées 2016 de la Commission des hydrosystèmes continentaux du CNFG. Depuis plus de 40 ans, de nombreuses études ont été menées par François Petit et ses collaborateurs sur le transport des sédiments par les rivières du massif ardennais et des régions périphériques. La diversité des processus et des problématiques abordées, des méthodes d'analyse et des périodes considérées nous ont amené à proposer un thème relativement général permettant de regrouper les études portant sur les sédiments de taille variée, depuis les fractions fines jusqu'aux éléments les plus grossiers de la charge de fond ainsi que d'aborder des échelles de temps différentes, depuis les héritages géomorphologiques des périodes froides du Quaternaire jusqu'aux futures évolutions dans le cadre de projets de restauration de cours d'eau.

We performed ac susceptibility measurements to explore the vortex dynamics and the flux-pinning properties of superconducting Pb films with an array of microholes (antidots) and not fully perforated holes (blind holes). A lower ac shielding together with a smaller extension of the linear regime for the lattice of blind holes indicates that these centers provide a weaker pinning potential than antidots. Moreover, we found that the maximum number of flux quanta trapped by a pinning site, i.e., the saturation number n(s), is lower for the blind hole array. [less ▲]

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 ▲]
