The distribution of the first domesticated animals and crops along the coastal area of Atlantic NW Europe, which triggered the transition from a hunter-gatherer-fisher to a farmer-herder economy, has been debated for many decades among archaeologists. While some advocate a gradual transition in which indigenous hunter-gatherers from the very beginn...
To investigate the influence of CO2 partial pressure on efficiency of CH4-CO2 swap from natural gas hydrates (NGHs), the replacement of CH4 from natural gas hydrate (NGH) is carried out with simulated Integrated Gasification Combined Cycle (IGCC) syngas under different pressures, and the gas chromatography (GC), in-situ Raman, and powder X-ray diff...

The suitability of organic Rankine cycle (ORC) technology for the conversion of low- and medium-grade heat sources to useful power has established this as a promising option in geothermal power-generation applications. Despite extensive research in this field, most of which has focused on parametric analyses and thermodynamic performance evaluation...
1. A diverse group of arthropods have adapted to the niches found inside the nests of social insects. Studies mostly focused on very specialised parasites residing in the brood chambers. However, the biology and strategies of symbionts occupying other niches, such as waste dumps, are underexplored. 2. Using a series of complementary experiments, th...
To enhance public service performance (PSP), public organizations are challenged to optimize and innovate their processes, techniques, policies and services. But can public organizations go too far when innovating and optimizing? Based on survey data from Dutch water authorities, we show that optimization initially contributes more to PSP than inno...

La dynamique de concentration de l'élevage a fortement réduit la densité porcine des zones de montagne. Pourtant cette filière joue un rôle pour le maintien d'activités d'abattage et de transformation dans ces territoires et participe à leur identité culturelle. L'avenir de ses élevages présente des enjeux multi-sectoriels dans le Massif Central où...
A destination des maitres d'oeuvre, maîtres d'ouvrages et exploitants du milieu de l'assainissement, ce guide présente de façon synthétique le fruit de travaux de recherche sur les zones de rejets végétalisées (ZRV). Une ZRV peut contribuer à réduire l'impact de la station de traitement des eaux usées sur le milieu récepteur en diminuant les flux d...
Methane recovery from natural gas hydrates via CH4-CO2 replacement is promising for its advantage in methane recovery and CO2 capture in the form of CO2 hydrates. However, up to date, it is still unclear what influence the CH4-CO2 replacement rate and CH4 recovery efficiency. In this work, the effects of the pressure on the dynamic of the replaceme...
