Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection
The Anatomical Record, EarlyView.Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Biotechnology and Bioengineering, EarlyView.ABSTRACT Oxygen supply is a critical parameter in 3D cell cultivation using bioreactors. Since bioreactor designs often prioritise practical constraints, understanding the oxygen supply dynamics of the media is crucial for achieving either uniform or spatially controlled oxygen delivery.

Study of the mathematical model for absorption and diffusion in ultra-napkins
Le Matematiche, 1995 We anlyse a mathematical model for absorption and diffusion of a fluid in ultra-napkins. We consider a diffusion equation coupled with an ordinary differential equation, subjected to a discontinuous Neumann boundary condition.We prove the existence and ...
