Concentraciones de progesterona sérica en cabras superovuladas con fsh 0 pmsg fuera de la época reproductiva

Revista Mexicana de Ciencias Pecuarias, 1992
Los objetivos fueron determinar el patrón de liberación de progesterona (P4) en cabras superovuladas con FSH, PMSG 0 PMSG mas anticuerpos monoclonales (ACM) contra la PMSG; y si-existe alguna asociación entre las concentraciones de P4 el día de la ...

Reduced order calculation method of subsynchronous oscillation mode of PMSG based wind farm connected with power grid based on Arnoldi method

Science and Technology for Energy Transition
Large scale wind turbine connected to the power grid is easy to induce subsynchronous oscillation. “Curse of dimensionality” will be encountered when the subsynchronous oscillation mode is analysed and evaluated based on the full-order model of the wind ...
