This paper introduces the indicators for surge arrester condition assessment based on the leakage current analysis. Maximum amplitude of fundamental harmonic of the resistive leakage current, maximum amplitude of third harmonic of the resistive leakage current and maximum amplitude of fundamental harmonic of the capacitive leakage current were used as indicators for surge arrester condition mon...

Single-phase powders of LaMnO3 and LaCoO3, lanthanum-based perovskites, were synthesized using the citric acid combustion method. The surface concentration La in obtained powder was higher LaCoO3 than LaMnO3. These samples decomposed 2-naphthol water dark. decomposition reaction is attributed to Mars–van Krevelen (MvK) mechanism because temperature dependence, activation energy, valence change ...

Single event burnout (SEB) is a great threat to gallium nitride (GaN) power devices for aerospace applications. This paper dedicated the investigation of SEB mechanism in GaN device using femtosecond pulsed laser. In test, commercial p-GaN was triggered by focused laser beam with wavelength 620 nm, and irradiation-sensitive area identified. We observed that damage modes were consistent results ...

seems to be no clear evidence that changes in permeability of the lung and airway linings play an additional role although transport studies with substances of varying molecular size (Egan) suggest that pores in the membranes may increase in radius during birth. The fetal lung produces enormous amounts of liquid (250 ml per day) and its ionic composition is unlike that of a plasma ultrafiltrate...

background and aims: from the past studies, it has been proved that consumption of heavy metals by humans may cause several chronicle problems like cancer, kidney and liver damage, high blood pressure and low blood pressure problems and etc. so, it has become very crucial to remove these heavy metals from industrial wastewater. the aim of this study was to find out a low cost and easy available...

Nitric oxide (NO) is a very active molecule involved in many and diverse biological pathways where it has proved to be protective against damages provoked by oxidative stress conditions. In this work, we studied the effect of two NO donors, sodium nitroprusside (SNP) and S-nitroso-N-acetylpenicillamine SNP-treated on the response of wheat (Triticum aestivum) to water stress conditions. After 2 ...
