Carlos M. Peláez,Carlos A.

Proposals for Regulation of Semiochemicals have generally proven unsuccessful as they are typically limited to the database used to develop them and ignore the effect of radial non-uniformity of the basic variables. However, fundamentally based models have made some progress in this direction. These models can be used to predict how various作者: 言行自由 時(shí)間: 2025-3-23 03:28 作者: Resection 時(shí)間: 2025-3-23 06:55
