The stresses produced at the low engine start-up speed are significant, increase beneath the surface and accumulate at the interface between the coating and the substrate. The elastic displacements of a fairly thin DLC coating prevents the stress accumulation on the substrate and protects it from adhesive wear.

Z. Koukouramkohler number that represents the ratio of the hydrodynamic and chemical characteristic time scales, and the chemical reversibility coefficient, and analyzed the resulting changes in the finger structures. The results are presented for flows with an initially stable as well as initially unstable front between the two reactants.

Root Exudates and Nutrient Cyclingcan indirectly influence turnover and availability of nutrients by interaction with soil micro-organisms. Thus, rhizodeposition is a key factor determining fluxes and pool sizes of mineral nutrients in ecosystems.

Modelling Nitrogen and Phosphorus Cycling in Agricultural Systems at Field and Regional Scalesst Liebig’s mineral theory and its modifications. For over a century and a half, dose-response experiments have addressed one or more of the following five basic questions (Van Noordwijk 1999): (1) to what extent do nutrients limit crop yield and quality?; (2) what is the quantity of nutrients suppl
