‘Voltage stability’ simplified

International Journal of Electrical Power & Energy Systems, 1992
Abstract This is not a physical or mathematical explanation or definition of voltage stability. Rather, it shows for a very simple case (to which, however, practically all cases of voltage stability or instability can be reduced) the very simple equations that apply.

Intraoperative Collection of Ascitic Fluid With Intra‐ or Postoperative Reinfusion in Ovarian Cancer: Safety and Feasibility of a Roller Pumping Method

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients with ovarian cancer often present with massive ascites, leading to significant protein loss during surgical procedures. Although cell‐free concentrated ascites reinfusion therapy (CART) is used in palliative settings to mitigate protein loss, its application in intraoperative settings remains unexplored.

Ensuring grid resilience: Voltage stability analysis and contingency ranking in electric power systems

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Modern-day power systems are highly stressed and operate close to the stability limit. The bus voltage variation in power systems generally infringes on the researcher's mind about voltage stability.

Method of static stability dominant identification

IET Generation, Transmission & Distribution, 2023
Two extreme cases of static stability are voltage stability and power angle stability. The general stability analysis only focuses on one of the voltage stability or power angle stability.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

VOLTAGE STABILITY ASSESSMENT IN RADIAL DISTRIBUTION NETWORK USING VOLTAGE STABILITY INDICES

ICTACT Journal on Communication Technology, 2020
Increased power demand and constrained power resources have made assessment of voltage stability in power system networks necessary in these days to predict voltage instability in order to ensure safe and secure operation of power systems. Also, due to numerous factors the existing power system networks are forced to operate at its peak limit ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
