Gas exchange patterns in insects can range from continuous, diffusive ventilation, to discontinuous gas exchange. Such a theory confines the chemistry and diffusive transport processes to an infinitesimally thin zone. Nonetheless, some diffusive upwelling does probably occur. Optical imaging systems may be divided into diffusive and ballistic imaging systems. Stringing can apply to both the diffusive bonding regime and the chemical bonding regime. It is an example of diffusive mass transfer. Models that use the diffusive wave assumption include MIKE SHE and LISFLOOD-FP.. For the most part, this is a phenomenon associated with diffusive bonding. It particular, no assumption was made on the type of diffusive motion under investigation. They are quite robust and efficient but somewhat more diffusive. This scheme is less diffusive compared to the second-order accurate scheme. Diffusive forces are somewhat like mechanical tethering at the molecular level. Other, less common types of wear are impact-, cavitation- and diffusive wear. Diffusive motion often dominates at the length-scale of spinodal decomposition.
