Shunt active power filter is commonly used to eliminate current harmonics generated in the source side due to presence of non-linear loads. This scheme consists of three phase three level diode clamped multilevel inverter and a DC capacitor that act as a shunt active power filter to mitigate the supply current harmonics and inject the required reactive power to non-linear loads. In this paper, ...
Certain patients with balance disorders report a 'visual vertigo' in which their symptoms are provoked or aggravated by specific visual contexts (e.g. supermarkets, driving or movement of objects). In order to determine the causes of visual vertigo (VV), we assessed symptoms, anxiety and the influence of disorienting visual stimuli in 21 such patients. In 17 out of 21 patients, a peripheral ves...
Twenty compounds were isolated from the aerial parts of Salvia willeana (Holmboe) Hedge, growing wild in Cyprus. These compounds comprise one new and one known acetophenone, one megastigmane glucoside, five phenolic derivatives, two caffeic acid oligomers, three flavonoids, two lignans, two triterpene acids, one monoterpene glucoside, and two fatty acids. The structures of the isolated compound...
A non-monotonic behavior of the velocity gradient a test particle revolving around rapidly rotating black hole in locally non-rotating frame reference is known as Aschenbach effect. This effect can serve distinguishing signature holes, being potentially useful for measurements astrophysical spins. paper generalization our previous research to motion spinning particles with non-zero cosmological...
Slowly rotating collapsing spherical shells have flat spaces inside and the inertial frames there rotate at ω s (t) relative to infinity. As first shown by Lindblom & Brill the inertial axes within the shell rotate rigidly without time delays from one point to another. Although the rotation rate of the inertial axes is changing the axes are inertial so, relative to them, there is neither an ˙ ω...
Idiopathic rapid eye movement sleep behavior disorder (iRBD) is a condition that often evolves into Parkinson's disease (PD). Therefore, by monitoring iRBD it is possible to track the neurodegeneration of individuals who may progress to PD. Here we aimed at piloting the characterization of brain tissue properties in mid-brain subcortical regions of 10 healthy subjects, 8 iRBD, and 9 early-diagn...
