Use of Carazolol at Pre-Synchronized Timed Artificial Insemination in Cows [PDF]

open access: yesActa Veterinaria Brno, 2008
Efficacy of the β-adrenergic receptor blocker (carazolol) at Timed Artificial Insemination (TAI) was investigated. Cows (n = 73) were pre-synchronized with two PGF 2α injections given 14 d apart to initiate the Ovsynch protocol at early and middle luteal stages 14 d later, and received ...

A Self-Adaptive Controller for Inverter With Seamless Transfer and Automatic Pre-Synchronization Capability [PDF]

open access: yesIEEE Access, 2020
A self-adaptive controller is proposed to operate inverter in both grid-connected (GC) state and stand-alone (SA) state and ensure seamless transfer between them without reconfiguring the control structure. The controller is mainly composed of phase-locked-loop (PLL) and two cascaded control loops.
