This paper represents the performance of a squirrel-cage High Temperature Superconducting Induction/ Synchronous Motor (HTS-ISM) based on nonlinear electrical equivalent circuit. The structure of the HTS-ISM is the same as that of the squirrel-cage type induction machine, and the secondary windings are fabricated by the use of the HTS wires. It has already been shown that based on the experimen...

Off-axis electron holography in the transmission electron microscope is used to record magnetic induction maps of closely spaced magnetite crystals in magnetotactic bacteria at room temperature and after cooling the sample using liquid nitrogen. The magnetic microstructure is related to the morphology and crystallography of the particles, and to interparticle interactions. At room temperature, ...

Introduction: PCOS is an important reproductive and endocrine disorder in women in the reproductive age. Present reports indicate that Vitex agnus-castus acts through hypothalamus-pituitary axis. This study was carried out to evaluate the effects of Vitex fruit hydroalcoholic extract on the alteration of sex hormones in a PCOS animal model. Methods: Following 14 days of monitoring of estrous...

b-Catenin is a multifunctional protein involved in cell adhesion and communication. In response to signaling by Wnt growth factors, bcatenin associates with nuclear TCF factors to activate target genes. A transactivation domain identified at the C-terminus of b-catenin can stimulate expression of artificial reporter genes. However, the mechanism of target gene activation by TCF/b-catenin comple...

Influence of different Agrobacterium rhizogenes strains on hairy roots induction and secondary metabolites production in Datura innoxia Mill.

We have investigated axis-inducing activities and cellular fates of the zebrafish organizer using a new method of transplantation that allows the transfer of both deep and superficial organizer tissues. Previous studies have demonstrated that the zebrafish embryonic shield possesses classically defined dorsal organizer activity. When we remove the morphologically defined embryonic shield, embry...

This paper presents analysis and evaluation of classical direct torque control(DTC), for controlling a symmetrical six phase induction motor (SPIM) under open phasefault conditions. The machine has two three-phase windings spatially shifted by 60 electricaldegrees. The strategy of the proposed method consists of choosing the switching modesaccording to the configuration of living phases in such...

This paper shows a parameter identification scheme for speed sensorless vector controlled induction motor using output inter-sampling approach and experimentally evaluates this method. It is well known that both the rotor speed and the rotor time-constant of induction motors cannot be identified under steady state operation. This is because vector control system of induction motors consists of ...
