Estimation of Critical Resistive Leakage Current of polymer housed ZnO surge arrester by electro-thermal modelling

Journal of Electrical Systems and Information Technology, 2018
In this study, a MATLAB/Simulink software based electro-thermal model of the polymer housed, gapless, 60 kV ZnO surge arrester is used for estimating the ‘ Critical Resistive Leakage Current (CRLC)’.

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

An EIRP Measurement Method of High-Power Microwave Systems Based on Near-Field Testing

International Journal of Antennas and Propagation
The equivalent isotropic radiated power (EIRP) of high-power microwave (HPM) systems is a core-evaluating indicator. In practical testing, locating a suitable test site for the far-field method becomes challenging due to the requisite antenna separation.

Identification method of all-operating-point admittance model for wind farms considering frequency-coupling characteristics

International Journal of Electrical Power & Energy Systems
Admittance identification is an effective tool to solve the issue of black-box admittance modeling in wind farms. However, due to the large operating range of wind farms, it is difficult to accurately identify the admittance model of wind farms under all

Characterization of Supraharmonic Emission from High-Power Electric Vehicle Chargers

, 2022
The increasing number of high-power electric vehicle (EV) charging stations in electricity grids introduces new challenges for the grid operators. Not only the high power demand of the chargers has an impact on the grids, the devices can also be a source

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Full Band Compact Power Arm Subsystem With High Directive Sample

IEEE Access, 2020
An output arm is the first subsystem in the microwave components chain connected immediately after the power amplifier. These arms are responsible for transferring the signal from the output port of the power amplifier to the standard line of the system.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
