Abstract: We present results from a new variant of a diffusion hopping model, the convective diffusive lattice model, to describe the behavior of a particulate flux around bluff obstacles. Particle interactions are constrained to an underlying… read more here.

DOI: 10.2136/sssaj2019.05.0167
Abstract: The determination of fixed ammonium (NH₄⁺) normally involves hydrofluoric acid (HF) digestion to decompose clay minerals following a rigorous pretreatment to control interference by organic nitrogen (N); however, the methods are tedious and time-consuming, and… read more here.
