Example Sentences

"Then, we evaluated the composition of the soil-pathogen microbiome. What we found is that the variation in pathogen composition in monocultures significantly predicted the yield when combined. When there are distinct pathogen communities, mixing them leads to a greater release of pathogens from your neighbors. The worst scenario is when a neighboring crop has the same pathogens. In that case, you're experiencing double density -- your crop pathogens and those from your neighbor crop."

From Science Daily

Thomson, then, any vortex ring, which we have supposed to be constituted of aetherial atoms, or atoms of electricity, may unite with any other vortex ring, thus producing a vortex ring of double density, which would possess double the electricity of the unit vortex ring.
