In this paper, the behavior of CO2 transmission in a micro direct methanol fuel cell (μDMFC) is investigated through both simulations and experiments. A model is built to describe the change of CO2 volume fraction in the anode channel under different operation parameters (e.g., current density,...

Sediments in estuary areas are recognized as the ultimate reservoirs for numerous contaminants, e.g., toxic metals. Multivariate analyses by chemometric evaluation were performed to classify metal ions (Cu, Zn, As, Cr, Pb, Ni and Cd) in superficial sediments from Lingdingyang Bay and to...

Despite high rates of cohabitation before marriage, and considerable efforts invested in the search for a life partner, a high number of marriages end in divorce. This paper develops a model of household formation and dissolution in which it may be rational for individuals to marry, fully...

The stylized fact that strong economic growth is usually accompanied with strong export growth leads many people to conclude that the export sector is the main driving force behind those episodes. The model in this paper, however, shows that the non-tradable sector may also generate high...
