This paper presents the modelling and parameter determination of an induction motor. The dynamic induction motor model was derived in relatively simple terms by using the concept of space vectors in d-q variables based on two-axis theory equations and the space phasor notation. A synchronous reference frame in which rotor flux lies on the d-axis was chosen with simplified dynamic equations and ...

objective: to compare efficacy, safety and tolerance of combination of mifepristone and misoprostol versus misoprostol-only in induction of late intrauterine fetal death (iufd). materials and methods: this prospective study included a consecutive series of 52 women gravid up to fourth with iufd after 28 weeks of gestation between january 2008 and june 2011. women were divided into two groups. f...

Objective(s): Autophagy-related 4B (ATG4B) plays an important role in the process of autophagy induction. However, the molecular events that govern the expression of ATG4B in this process are not well known. Materials and Methods: Human ATG4B 3'-UTR region (1377 nt) containing miR-34a/miR-34c-5p binding site was amplified by PCR. Luciferase assay was used to assess the activity of reporter gene...

the antioxidant activities of tbhq, bht and tocopherol mixtures at different concentrations (0, 100, 200, 400 mg/kg) have been evaluated by the application of differential scanning calorimetry (dsc) and rancimat apparatus. rancimat apparatus that measures the secondary oxidation products was set at 110 ⁰c with an air flow of 18-20 l/h to measure the induction period (ip) of the samples. the dsc...

The anterior aspect of the mouse primitive streak resembles the organizer of Xenopus and chick in terms of its developmental fate, ability to alter pattern in the chick limb bud and with respect to the repertoire of genes that its constituent cells express. However, until now there has been no direct evidence that the mouse node organizes pattern during gastrulation, nor that the exceptionally ...

MicroRNAs (miRNAs) are post-transcriptional modulators of gene expression and play an important role in reprogramming process; however, relatively little is known about the underlying regulatory mechanism of miRNAs on how they epigenetically modulate reprogramming and pluripotency. Here, we report that the expression level of microRNA-134 (miR-134) was low in mouse embryonic stem cells (mESCs) ...

Introduction: Different mechanisms are involved in stress induced analgesia (SIA) and hyperalgesia (SIH). Repeated stress induces development of tolerance to SIA. The role of HPA axis and Gs signaling pathway in these effects are investigated in the current study. Methods: Forced swim stress (5 min/day) in water (20±1 ºC) was employed to adult male Wistar rats (200-250 g). The nociceptive t...
