We consider one-step and two-step simple models of anaerobic digestion which are able to adequately capture the main dynamical behavior of the full anaerobic digestion model ADM1 and has the advantage that a complete analysis for the existence and local stability of their steady states is available. We describe the best operating conditions for bio...

Limiting global warming to 1.5°C above pre-industrial levels by 2050 requires achieving net zero emissions of greenhouse gases by 2050 and a strong decrease in methane (CH4) emissions. Our aim was to connect the global need for mitigation of the emissions of greenhouse gases and enteric CH4 from ruminant production to basic research on the biologic...

There has been a growing focus on healthy aging in the political agenda. Discourses contained within policy documents have the potential to shape our notions of healthy aging and well-being. This comprehensive critical document analysis of provincial aging policies in Newfoundland and Labrador (2006-2015) contributes to a larger research study expl...
Arbuscular mycorrhizal (AM) fungi play a key role in determining ecosystem functionality. Understanding how diversity in the fungal community affects plant productivity is therefore an important question in ecology. Current research has focused on understanding the role of functional complementarity in the fungal community when the host plant faces...
Drawing on an adapted CDM model, we present evidence on the role of strategic and operational absorptive capacity on innovation and productivity across industries in developing economies. Using a pooled cross-sectional sample from Chilean innovation surveys, we find that greater absorptive capacity (ACAP) helps firms to increase their innovative in...
Pour répondre à la demande des aliments aussi bien en quantité qu’en qualité de la population croissante en Afrique, il faudra appliquer les technologies agricoles appropriées aux sols fragiles de ce continent pour augmenter la productivité et aboutir à la sécurité alimentaire. Dans le contexte du Rwanda, l’usage des fertilisants et des pesticides ...

Hydraulic fracturing horizontal well is the key technology of tight gas development. After fracturing, the gas well shows the characteristics of great difference in production energy and many factors affecting production capacity. Therefore, taking 10 fractured horizontal wells in JQ gas field in Sichuan Basin as an example, comprehensively conside...
