DEP domain containing mammalian target of rapamycin (mTOR)-interacting protein (DEPTOR), a recently identified mTOR-interacting protein, is a novel candidate oncogene. Previous studies reveal that high DEPTOR expression is required to maintain PI3K and Akt activation and to inhibit apoptosis. However, its significance in differentiated thyroid carcinoma (DTC) is not yet known. The present study...
A comparison was made of the incidence of postoperative myalgia (POM) and fasciculations when atracurium (ATR) or d-Tubocurarine (DTC) was given prior to succinylcholine (SDC) for facilitation of tracheal intubation. The subjects were 44 ASA physical status I or II outpatient females undergoing laparoscopy. They were assigned to one of three groups: Group 1 received 0.025 mg/kg ATR; Group 2 rec...
Simulation studies of three synchronous reluctance motor (SynRM) control strategies are presented: field-oriented (FOC), direct torque (DTC), and finite-set model-predictive (FS-MPC). FOC uses linear controllers pulse-width modulation to the fundamental components load voltages vectors. In contrast, DTC FS-MPC nonlinear wherein voltage vectors directly generated in absence a modulator. Theoreti...
Sommario La ricerca del linfonodo sentinella con iniezione di radiocolloidi nel carcinoma differenziato della tiroide (DTC) è ancora oggi una tecnica dibattuta e non comunemente impiegata nella pratica clinica, in quanto attualmente contemplata dalle linee guida ATA. Obiettivo questa rassegna è, pertanto, quello raccogliere attuali luci ombre linfoscintigrafica DTC, per stimolare la futura racc...
INTRODUCTION Over the last few years, many private companies are advertising direct-to-consumer genetic testing (DTC GT), mostly with no or only minor clinical utility and validity of tests and without genetic counselling. International professional community does not approve provision of DTC GT and situation in some EU countries has been analysed already. The aim of our study was to analyse cu...
At present, induction motors are the dominant drives in various industries. It is quite cumbersome to control an induction motor (IM) because of its poor dynamic response in comparison to the DC motor drives. The central theme of Vector Control (VC) is to decouple the stator current of the IM into two orthogonal components and is to control these two components individually so as to achieve an ...
AC drives are more predominant than dc drives. Ac drives require control of frequency, current and voltage for variable-speed applications. The difference between the traditional vector control and the DTC is that the DTC has no fixed switching pattern. The DTC switches the inverter according to the load needs. Though conventional DTC (CDTC) is simple, easy to implement generates substantial st...
Cancer dormancy refers to the prolonged clinical disease-free time between removal of the primary tumor and recurrence, which is common in prostate cancer (PCa), breast cancer, esophageal cancer, and other cancers. PCa disseminated tumor cells (DTC) are detected in both patients with no evidence of disease (NED) and advanced disease (ADV). However, the molecular and cellular nature of DTC is un...
Received Feb 13, 2017 Revised Apr 17, 2017 Accepted May 1, 2017 A Constant Switching Frequency Direct Torque Control (CSF-DTC) with low switching losses Space Vector modulation (SVM) for Permanent Magnet Synchronous Motor (PMSM) drive is proposed in this work. The CSF-DTC combines Field Oriented Control (FOC) and basic DTC advantages. Indeed, the proposed control strategy improves the basic DTC...
در این مقاله برای تخمین وضعیت روتور در درایو موتور بدون سنسور BLDC از روش نسبت توابع شار خط به خط، استفاده شده است. این روش، نسبت به سایر روشهایی که برای تخمین موقعیت روتور مورد ارزیابی قرار میگیرند، حجم نرمافزار و سختافزار کمی داشته و لذا پیاده سازی آن آسان و هزینه ساخت نیز کمتر است. همچنین این روش در بازه وسیعی از سرعت کارایی مناسبی دارد و تخمین وضعیت روتور مستقل از سرعت و فرکانس روتور می...
