10.8 Work and Power for Rotational Motion

2016/08/03We can apply the definition of power derived in Power to rotational motion. From Work and Kinetic Energy, the instantaneous power (or just power) is defined as the rate of doing work, P = dW dt. P = d W d t. If we have a constant net torque, (Figure) becomes W =τ θ W = τ θ and the power is.

Optimal stomatal behavior with competition for water and risk

2016/11/15Plants lose water and take up carbon through stomata, whose behavior has major influences on global carbon and water fluxes. Yet both competition for water and the potential fitness costs of hydraulic damage during water stress could alter how stomata behave. Here, we add variable xylem conductivity to water and carbon costs of low-xylem water potentials to the classic stomatal
