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...

This article presents a novel power-angle control method of the doubly fed induction generator dc system based on regulating air gap flux vector. The relationship between angle electromotive force (EMF) vector and stator output power is revealed in this article, which can be used for controlling directly. Since frequency determined by rotating speed EMF vector, generated loop that avoid classic...

During early Drosophila embryogenesis, several zygotic gene products act to establish a posttranscriptional activity gradient of the morphogen DPP. Among these molecules, Tolloid, a putative metalloprotease related to BMP-1, enhances DPP function, while SOG, an ortholog of the Xenopus organizer Chordin, inhibits DPP function. Using epistasis tests and a Xenopus secondary axis induction assay, w...

BACKGROUND AND AIM Glutamine is an important energy source for the intestinal epithelium, and its supplementation protects intestinal epithelial cells by induction of glutathione. However, mechanisms of glutathione induction in cells at various stages of differentiation along the crypt to villus axis are not well understood. This study examined induction of glutathione in response to glutamine ...

This paper presents a detailed analysis of dynamic properties and accuracy issues the torque-producing stator current control loop for vector-controlled induction motor drives. In this paper, necessary mathematical description vector an is shown with respect to x-axis y-axis in rotating reference frame. A derivation steady-state error scheme without decoupling algorithm described. The presented...

One of the most critical problems in induction motor drive is the knowledge of the current value of some induction motor parameters such as the rotor time constant, which depends strongly on temperature and frequency. This problem won’t be easy to solve because of the high coupling between parameters in the nonlinear induction motor model. In order to determine the rotor time constant, this pap...

in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...

We report here a 47-year-old woman with isolated adrenocorticotropin (ACTH) deficiency (IAD). She presented impaired renin-angiotensin-aldosterone (R-A-A) system and suppressed parathyroid hormone (PTH)-vitamin D system. She showed severe hyponatremia due to secondary adrenocortical insufficiency, which was deteriorated by hypoaldosteronism. She also showed hyperphosphatemia and relative hyperc...

CRH-binding protein (CRH-BP) regulates activation of the hypothalamic-pituitary-adrenal (HPA) axis by binding and inhibiting CRH. We investigated for the first time transcriptional regulation of the human CRH-BP promoter using transient transfections. Estrogen receptors (ERs) contributed to ligand-independent constitutive activation of the promoter, whereas in the presence of estradiol ERalpha ...
