The increased prevalence of Diabetes mellitus, the comorbid associations and complications among global population has led to a dependency for treatment options with multiple modalities. One such option is SGLT2 inhibitor (SGLT2i) class drugs. SGLT2i have been demonstrated improve glycemic control while providing cardiovascular (CV) renal benefits in patients T2DM. inhibitors comprising canagli...
A high-frequency longitudinally driven giant magnetoimpedance ~GMI! effect has been measured in stress-annealed Fe73Cu1Nb1.5V2Si13.5B9 nanocrystalline ribbons. Based on how the impedance phase varies with the external magnetic field, it becomes clear that the imaginary part of the complex permeability, m9, which is related to magnetic losses, plays an important role in the high-frequency longit...
Advances in magnetoresistive (MR) type sensors provide a new technique for nondestructive evaluation NDE of metal structures. GMR and GMI sensors provide high sensitivity and reduced size, with GMI sensors also adding capabilities of high frequency range of measurements. Being produced with thin film processing techniques, the manufacturing cost of these sensors is low. An example is considered...
BACKGROUND There is strong evidence to suggest that multiple work-related health problems are preceded by a higher need for recovery. Physical activity and relaxation are helpful in decreasing the need for recovery. This article aims to describe (1) the development and (2) the design of the evaluation of a daily physical activity and relaxation intervention to reduce the need for recovery in of...
BACKGROUND Phantom limb pain (PLP) is characterized by the anatomical shifting of neighbouring somatosensory and motor areas into a deafferented cortical area of the brain contralateral to the amputated limb. It has been shown that maladaptive neuroplasticity is positively correlated to the perception of PLP in amputees. Recent studies support the use of graded motor imagery (GMI) and its compo...
Transport from the surface to the lowermost stratosphere (LMS) can occur on timescales of a few months or less, making it possible for short-lived tropospheric pollutants to influence stratospheric composition and chemistry. Models used to study this influence must demonstrate the credibility of their chemistry and transport in the upper troposphere and lower stratosphere (UT/LS). Data sets fro...
بیشینه ی تغییر امپدانس الکتریکی یک ماده ی فرومغناطیسی نرم با تغییر میدان مغناطیسی اعمالی بر آن را امپدانس مغناطیسی بزرگ 1 gmiمی گویند . روی این اثر به لحاظ تئوری و تجربی کارهای زیادی انجام شده است . از جمله موادی که روی آنها اثر gmi انجام شده است ، نوارها و سیم های آلیاژی ، چند لایه ای ها ، فیلم ها ، میکرو سیم ها ، میکرو تیوب ها ، ترکیب هایی به صورت آمورف و نانوبلوری انجام شد که هر کدام از آن...
The optimization of the high frequency giant magnetoimpedance (GMI) effect and its magnetic field sensitivity in melt-extracted Co69.25Fe4.25Si13B12.5Nb1 amorphous microwires was systematically studied through a multi-step Joule annealing (MSA) technique. surface morphology, microstructure, property, radio GMI response Co-rich were explored using techniques like microscopy, magneto-optical Kerr...
A thin film giant magneto impedance (GMI) based on magnetic field sensor has been developed using electrodeposited Ni-Fe permalloy. Chemical composition, surface morphology, and magnetic properties of Ni-Fe permalloy were characterized as a function of plateup parameters, and process conditions were established to deposit a Ni-Fe thin film with a high permeability (~1000) and a low coercivity (...
A highly sensitive and large working range giant magnetoimpedance (GMI) effect is found in the novel nanostructure: nanobrush. The nanostructure is composed of a soft magnetic nanofilm and a nanowire array, respectively fabricated by RF magnetron sputtering and electrochemical deposition. The optimal GMI ratio of nanobrush is promoted to more than 250%, higher than the pure FeNi film and some s...
