In recent years, the penetration of renewable energy sources (RES) in microgrids and distribution system feeders has increased manifold. Moreover, advancement power electronics-based devices significantly number sensitive loads. Variations voltage under intermittent RES create functional problems with loads, necessitating regulators (VR) installation. this paper, two custom devices: dynamic res...
In this paper, a new dual function fault current limiter-dynamic voltage restorer (FCL-DVR) topology is proposed. The proposed structure, in addition to performing routine FCL tasks, can be used improve the quality of point common coupling (PCC). A salient feature FCL-DVR its reduced number semiconductor switches and gate drive control circuit components. Perhaps, variety structure have been bu...
Background: The purpose of the study was to evaluate the applicability of F-labelled amyloid imaging positron emission tomography (PET) agent [F]flutemetamol to detect changes in brain beta-amyloid (Aβ) deposition in vivo in APP23, Tg2576 and APPswe-PS1dE9 mouse models of Alzheimer's disease. We expected that the high specific activity of [F]flutemetamol would make it an attractive small animal...
BACKGROUND The purpose of the study was to evaluate the applicability of (18) F-labelled amyloid imaging positron emission tomography (PET) agent [ (18) F]flutemetamol to detect changes in brain beta-amyloid (Aβ) deposition in vivo in APP23, Tg2576 and APPswe-PS1dE9 mouse models of Alzheimer's disease. We expected that the high specific activity of [ (18) F]flutemetamol would make it an attract...
امروزه تقاضا برای کیفیت توان به منظور ایمنی تجهیزات الکتریکی و رضایت مصرف کننده ها بسیار افزایش یافته است. یکی از تجهیزاتی که برای بهبود کیفیت توان الکتریکی استفاده می شود، dvr می باشد. dvr اینورتری است که به صورت سری با خطوط شبکه قرار می گیرد. در هنگام تغییر ولتاژ خط، dvr ولتاژی را با دامنه و فاز قابل کنترل، به صورت سنکرون با ولتاژ منبع، توسط ترانسفورماتور، به خط تزریق می کند تا ولتاژ بار را د...
Much of the Wulst and dorsal ventricular ridge (DVR) in birds, which together make up the part of the avian telencephalon functionally resembling mammalian cerebral cortex, projects to the striatum. Those connections arise from neurons projecting additionally to the brainstem as well as from neurons projecting only within the telencephalon. As part of an effort to further characterize corticost...
To investigate the responses of descending vasa recta (DVR) to deformation of the abluminal surface, we devised an automated method that controls duration and frequency of stimulation by utilizing a stream of buffer from a micropipette. During stimulation at one end of the vessel, fluorescent responses from fluo4 or bis[1,3-dibutylbarbituric acid-(5)] trimethineoxonol [DiBAC₄(3)], indicating cy...
Experimental data from vibrationally and rotationally resolved laser induced fluorescence experiments have been used to produce potential energy surfaces (PES) for the excited à 2Σ+ states of the Ar·SH and Kr·SH van der Waals complexes. This was done using a potential energy functional form first suggested by Bowman and co-workers1 for Ar·OH/D. A discrete variable representation (DVR) of the vi...
In 1982, Betamax, the world’s first personal recording service was ruled as a fair use in court. Although the copyright holders of TV content claimed that Betamax was an infringement of copyright, the court determined that the benefits of personal recording services were significant and that the copyright holder’s profits could be protected because the original service was of better quality and...
INTRODUCTION Fractures of the distal radius are common. Malreduced fractures are associated with residual functional deficiency. There has been a trend over the last few years for using fixed angle volar locking plates to surgically stabilise this injury. Our unit uses the DVR(®) plate (DePuy, Warsaw, IN, US). Nevertheless, it is unknown whether the normal bony anatomy is recreated or merely re...
