This paper presents the structure of a sensor for converting multiphase primary currents into secondary voltage reactive power networks with renewable energy sources, an algorithm modeling processes in sensor, which provides control over current and device. The dynamic characteristics investigated are given on basis proposed analytical expressions. A graph model to study conversion output volta...

We theoretically investigated the properties of ultraviolet secondary radiation generated under action three-color ionizing pulses obtained from parametric light generators. show that combination components in spectrum electron currents such can form a strictly exponentially decreasing sequence. For moderately short pump pulse durations (30 fs at 800 nm main field) with use this effect, it is p...

Evidence from pharmacological studies suggests that induction of the acrosome reaction of mammalian spermatozoa by solubilized zona pellucida, and possibly by progesterone, is dependent upon Ca2+ influx through voltage-operated Ca2+ channels. Studies on Ca2+ accumulation and membrane potential in ligand-stimulated or artificially depolarized spermatozoa support such a conclusion. Electrophysiol...

This paper investigates for transformation of the distorted current low order higher harmonic self-generation phenomenon tested inductive transformers. The influence main component and 3rd primary on RMS values 5th, 7th 9th self-generated harmonics is analyzed. research indicate that change value causes variation lower generated in to secondary current. Therefore, this a challenging which have ...

Introduction: Neurons in layer II and III of the somatosensory cortex in rats show high frequency (33 ± 13 Hz) of miniature excitatory postsynaptic currents (mEPSCs) that their rates and amplitudes are independent of sodium channels. There are some changes in these currents in neurodegenerative and psychological disorders. Regarding to well known roles of the neuromodulatory brain systems in...

The aim of this paper is to extend a hybrid protection plan for Power Transformer (PT) based on MRA-KSIR-SSVM. This paper offers a new scheme for protection of power transformers to distinguish internal faults from inrush currents. Some significant characteristics of differential currents in the real PT operating circumstances are extracted. In this paper, Multi Resolution Analysis (MRA) is use...

An oil spill model coupled with a hydrodynamic model was developed to simulate the spread of oil slick in real marine conditions considering the effects of tidal currents, wind and wave. The hydrodynamic model is verified using the measurements of tidal elevations and current speeds at the Persian Gulf. Effect of various governing factors on oil slick movement, tidal currents, wind and wave, ar...

There is strong evidence demonstrating that nifedipine dissolved in ethanol selectively inhibits only L-type Ca2+ current. In addition, acute ethanol exposure reduces voltage-dependent calcium currents. In the present study, we investigated the antagonistic effect of fixed concentration of nifedipine dissolved in different concentration of ethanol on L-type Ca2+ current. In a Na+-K+ free soluti...

let r be a commutative ring with non-zero identity and m be a unital r-module. then the concept of quasi-secondary submodules of m is introduced and some results concerning this class of submodules is obtained
