The interval from onset of estrus to preovulatory luteinizing hormone (LH) release, conception and fertilization rates, and number of accessory spermatozoa per ovum at 48 hr postmating in untreated cyclic ewes and fn progestogen-pregnant mare serum gonadotropin (PMSG) treated, anestrous ewes were compared in efforts to identify sources of lowered fertility for matings induced in anestrous ewes ...
Two experiments were conducted to assess the effect of buck exposure to synchronize estrus in mature and pre-pubertal norgestomet-treated crossbred (criolloxdairy breeds) goats. In experiment 1, 100 mature goats (25 per group) under range conditions were either teased at 48 or 24h before Sincromate-B (SMB; 9 days treatment of 2mg norgestomet) implant withdrawal. A third group was exposed to buc...
This paper deals with permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS) integrated with grid with two back to back connected converters with a common DC link. The aim of this research is to model control of direct driven 1.5 MW wind turbine permanent magnetic synchronous generator (PMSG) which feeds alternating current (AC) power to the utility grid .The m...
Pregnant rats were given one of the following doses of misulban on day 15 of pregnancy : 0.25, 0.36, 0.52, 0.75, 0.82, 0.88 or 0.95 mglkg. In the three-month old offspring it was observed that : 1) The number of cyclic rats decreased according to the dose of misulban given to the mothers ; 2) Cyclic rats were given an injection of 20 IU of PMSG at metcestrus followed by an injection of 150 IU o...
Ovulation rate, fertilization rate and prenatal mortality were studied in yearling beef heifers treated with PMSG or FSH and in non-treated controls. Oestrus was synchronized in 50% of the animals in each treatment with an oral progestagen. The gonadotrophin injections were given during the normal oestrous cycle or during the progestagen-administration period. All heifers were inseminated 6 to ...
This paper presents the results of experimental investigation of a low-power wind energy conversion system (WECS), based on a permanent-magnet synchronous generator (PMSG) connected directly to the turbine. A development system was built in order to carry out the experiments. Its detailed description is also provided. The development system can work as an autonomous system for remote sites or a...
The current study designed to evaluate the role of pluripotent stem cells (iPSc) on experimentally-induced ovarian ablation (OA) by evaluating hematological parameters, FSH and E2 changes, molecular histopathological examination. 50 female rats were divided into five groups with 10 in each group. Group (1): control (2): injected Doxorubicin (DOX) (3 mg/kg) Cyclophosphamide (CYP) (50mg/kg) disso...
The ability of rats or mice to withstand the consequences of injury to myelinated axons in the CNS was previously shown to depend on the ability to manifest a T cell-mediated protective immune response, which is amenable to boosting by myelin-specific T cells. Here we show that this ability, assessed by retinal ganglion cell survival after optic nerve injury or locomotor activity after spinal c...
Novel therapies for lung cancer are being explored nowadays with local therapies being the tip of the arrow. Intratumoral chemotherapy administration and local microwave ablation have been investigated in several studies. It has been previously proposed that lipiodol has the ability to modify the microenvironment matrix. In our current study we investigated this theory in BALBC mice. In total 1...
Simple control of a stand-alone variable speed wind turbine with permanent magnet synchronous generator (PMSG) is presented in this paper. PMSG fed different types loads by means converter where switched mode rectifier connected to the PMSG, boost DC-DC converter, and voltage source inverter (VSI). The operated at measured it tested estimated which based on power calculation power, generating e...
