Superovulation and embryo quality in beef cows using PMSG and a monoclonal anti-PMSG

Theriogenology, 1991
The long half-life of pregnant mare serum gonadotrophin (PMSG) reduces its application in the superovulation of cattle; thus, a monoclonal antibody to PMSG (anti-PMSG) was administered at the onset of estrus to increase the number of transferable embryos. Angus, Hereford and Angus x Hereford cows (n = 149) 3 to 9 yr old were assigned randomly to one of

CWOA-PMSG: Crossover assisted WOA Optimization for Controlling PMSG in Wind Generation System

2018 International Conference on Electrical, Electronics, Communication, Computer, and Optimization Techniques (ICEECCOT), 2018
In wind power generation, Permanent-Magnet Synchronous Generators (PMSGs) plays its major role in generating high-efficient, high-reliability, as well as low-cost power generation. This paper intends to propose a new control model for the interior PMSG (IPMSG) driven, in which the polynomial constraints, are optimally controlled to attain the peak or ...

Adaptive control of wind PMSG

2016 17th International Scientific Conference on Electric Power Engineering (EPE), 2016
The paper suggests an adaptive control of the wind permanent magnet synchronous generator (PMSG) driven by a variable speed wind turbine. Processes in wind generator have been studied using a mathematical model. The results show suitability of using adaptive control using Optimal Singular Adaptive (OSA) observer.

Influence of PMSG antiserum on serum progesterone and estrous cycles of PMSG-treated gilts

Canadian Journal of Animal Science, 1992
Forty-seven prepubertal gilts (88.4 ± 0.9 kg) received an injection of 750 IU PMSG to stimulate ovarian activity. After 96 h, 23 gilts received an injection of an anti-PMSG serum. Blood samples were obtained at the time of PMSG injection (day 0) and at 2, 4, 6, 11, 18, 25 and 32 d.

Torsional vibration analysis of grid-forming PMSG wind turbine

IET Conference Proceedings, 2023
In this paper, a small-signal model of a grid-forming (GFM) permanent magnet synchronous generator (PMSG) wind turbine is developed and presented, which can be utilized to study the electromechanical dynamics. The study demonstrates that there is a significant negative impact of GFM control on the torsional mode of the two-mass drive train, and ...

Changes in follicular populations following treatment of buffaloes with PMSG (eCG) and Neutra-PMSG for superovulation

Animal Reproduction Science, 1999
Some 19 buffaloes were synchronized by administration of a prostaglandin (PG) salt Lutalyse, with a single intramuscular (i.m.) injection of 25 mg at day -13. Luteolysis was induced by administration of 50 mg PG, in divided doses of 30 and 20 mg i.m. 12 h apart on day 0 of experiment. The 30 mg PG injection was designated as 0 h of experiment.

Increased ovulation rates in PMSG-stimulated beef heifers treated with a monoclonal PMSG antibody

Theriogenology, 1994
The effects of PMSG dose and monoclonal anti-PMSG treatment on the superovulatory response were investigated in beef heifers. Heifers were administered 1500 (n=22), 3000 (n=21) or 4500 (n=21) IU of PMSG on Day 8, 9 or 10 after estrus, and half of the heifers in each group received a neutralizing dose of anti-PMSG at the time of first insemination (60 h

Wind energy conversion system using PMSG

2015 International Conference on Recent Developments in Control, Automation and Power Engineering (RDCAPE), 2015
The applications of wind energy develops much more rapidly than the other renewable resources such as solar, geothermal etc. in the 21st century. It becomes the third core energy resource following non conventional fuels as oil and chemical. Electrical energy generated by wind power plants is the fastest developing and most promising renewable energy ...

Factors affecting superovulation in heifers treated with PMSG

Theriogenology, 1996
In this study we determined 1) if the immunoneutralization of PMSG affected the ovulatory response, the number of large follicles and embryo yield compared with that of PMSG alone or pFSH, and 2) whether the stage of the estrous cycle at which PMSG was injected affected the ovulatory response and yield of embryos in superovulated heifers.

PMSG fault diagnosis in marine application

2016 20th International Conference on System Theory, Control and Computing (ICSTCC), 2016
This paper presents a fault diagnosis (FD) method for on line monitoring of stator winding partial inter-turn fault and severe faults, in permanent magnet synchronous generator (PMSG) used in shaft generator system in marine applications. The faulty machine is represented in state space model based on the dq-frame transformation.
