1. Despite their low contribution to forest carbon stocks, lianas (woody vines) play an important role in the carbon dynamics of tropical forests. As structural parasites, they hinder tree survival, growth and fecundity; hence, they negatively impact net ecosystem productivity and long-term carbon sequestration. 2. Competition (for water and light)...

BackgroundCharacteristics of the neighborhood built environment are associated with physical activity (PA). However, few studies with representative samples have examined environmental correlates of domain-specific PA in Latin America. We examined the associations of the perceived neighborhood built environment with domain-specific PA in a large sa...

Dans les grandes villes, les disparités urbaines se traduisent en partie par une inégale répartition des différents groupes sociaux dans l’espace géographique mais surtout corollairement par des inégalités d’accessibilité des lieux de résidence aux lieux de travail, aux services, aux commerces, aux équipements culturels etc. Pour étudier les phénom...
While retention in commercial ultrafiltration membranes is commonly governed by size exclusion, addition of charged polyelectrolytes to the membrane surface has been proposed as a facile and inexpensive method to modulate retention during filtration of charged compounds, such as proteins. This study demonstrates that selected combinations of common...

We present the development and application of X-ray Computed Tomography (CT) for the determination of the adsorption properties of microporous adsorbents and the study of breakthrough experiments in a laboratory fixed-bed adsorption column. Using the model system CO2/helium on activated carbon, equilibrium and dynamic adsorption/desorption measurem...

Retirement induces changes in the composition of daily physical activity. Our aim was to examine changes in accelerometer-measured physical activity around transition to statutory retirement among men and women by occupational category and by preretirement modes of commuting. We included 562 workers (mean [SD] age, 63.3 [1.1] yr; 85% women) from th...
Lead-free double perovskites have great potential as stable and nontoxic optoelectronic materials. Recently, Cs2 AgBiBr6 has emerged as a promising material, with suboptimal photon-to-charge carrier conversion efficiency, yet well suited for high-energy photon-detection applications. Here, the optoelectronic and structural properties of pure Cs2 Ag...
