Different types of permanent magnet generators for wind power application have been subject of research during last two decades. In this thesis different topologies of electrical generators have been investigated for small scale vertical axis wind turbine application. A two stage induction generator is proposed as a alternative solution with respect to the cost of such a system. However, a bigg...

Peptide mass-signature genotyping (PMSG) is a scanning genotyping method that identifies mutations and polymorphisms by translating the sequence of interest in more than one reading frame and measuring the masses of the resulting peptides by mass spectrometry. PMSG was applied to the RDS/peripherin gene of 16 individuals from a family exhibiting autosomal dominant macular degeneration. The meth...

The increasing demand of electric power necessitates the establishment of new generating stations. Wind energy conversion system (WECS) is more attractive due to its mature and clean aspects. During last decades the variable speed wind turbine concept has been increasingly receiving attention due to the fact that it is more controllable and efficient, and has good power quality. The wind turbin...

The aim of this study was to exam sexual receptivity in rabbit does at the day of artificial insemination using the colour of vulva, rectal temperature and vagina cytology by the percentage of keratinized cells. A total of 36 multiparous INAT does were used for this purpose and they were injected with PMSG before artificial insemination (AI). 48 hours after injection, does detected receptive, w...

Permanent magnet generators for renewable energy application have been subject of research during last two decades. Several kinds of rotating electrical generators exist for several applications, including synchronous, induction and DC machines. Doubly Fed Induction Generator is proposed as an alternative solution with respect to the cost of such a system. However, a bigger emphasis in the repo...

Grid-connected wind turbines are fluctuating power sources that may produce flicker during continuous operation. This paper presents a simulation model of a MW-level variable speed wind turbine with a full-scale back-to-back power converter and permanent magnet synchronous generator (PMSG) developed in the simulation tool of PSCAD/EMTDC. Flicker emission of this system is investigated. The 3p (...

The efficiency of the variable speed wind energy conversion systems (WECS) can be greatly improved using an appropriate control strategy. In this paper, nonlinear control for wind energy conversion system (WECS) based on the permanent magnet synchronous generator (PMSG) is investigated in order to maximize the generated power from wind turbine. The control strategy combines the technique of max...

The aim of this trial was to evaluate the effectiveness (fertility and lambing) of priming with a single injection of progesterone plus PMSG in anovulatory lactating Sarda ewes subjected to the ram effect (RE) in spring. Thirty ewes (P4 group) were i.m. injected with 30 mg progesterone and 500 IU PMSG 36 h before ram introduction (d 0). This treatment was compared to a 12-day treatment with flu...

Ten primiparous river buffaloes of the Miankaleh peninsula, northern Iran in the nonbreeding season from the native herds were selected. The buffaloes were divided into two groups (n=5) and were injected intramuscularly with gonadotropin releasing hormone (GnRH) and a controlled internal drug-release device (CIDR) inserted on the fi rst day. Ten days later, administration of follicle stimulatin...

The present study was performed to optimize a superovulation protocol in rats in order to produce a large number of good-quality embryos suitable to develop rat embryonic stem (rES) cells. We first evaluated the ovulation kinetics of three rat strains: Wistar, Fisher and ACI/N. Animals (n=30 per strain) were treated with 50 IU of pregnant mare serum gonadotrophin (PMSG), and ovulation was induc...
