CONTROL OF RIPPLE ELIMINATORS TO IMPROVE THE POWER QUALITY OF DC SYSTEMS AND REDUCE THE USAGE OF ELECTROLYTIC CAPACITORS

Control of Ripple Eliminators to Improve the Power Quality of DC Systems and Reduce the Usage of Electrolytic Capacitors

The problem of voltage/current ripples has become a primary power quality issue for dc systems, which could seriously degrade the performance on both the source side and the load side and lead to reliability concerns.In this paper, a single-phase Pulse width modulation-controlled rectifier is taken as an example to investigate how active control st

Experiences of mothers with preterm babies on support services in Neonatal Intensive Care Unit of a mission hospital in Ghana

Background: Hospitalisation of a preterm baby presents significant burden to parents, especially mothers.However, little evidence on supportive services to improve self-efficacy for mothers on caring for their preterm babies exist.This study explored the experiences of mothers of preterm babies regarding the support services they received at the Ne

Hypoxic mesenchymal stem cell-derived exosomal circDennd2a regulates granulosa cell glycolysis by interacting with LDHA

Abstract Background Premature ovarian insufficiency (POI) is an ovarian dysfunction disorder that significantly impacts female fertility.Ovarian granulosa cells (GCs) are crucial somatic components supporting oocyte development that rely on glycolysis for energy production, which is essential for follicular growth.Hypoxia-induced exosomal circRNAs
