Frequency Considerations in GIC Applications [PDF]

open access: yesSpace Weather, 2021
Abstract Geomagnetically induced currents (GIC) are a phenomenon well known for its negative effects on the operations of power systems. To efficiently mitigate them requires different types of power system modeling, from GIC to alternating current harmonic generation, to three‐dimensional finite element models of transformers.

Physicochemical and remineralisation properties of calcium silicate and glass ionomer cements applied in simulated caries‐affected dentine [PDF]

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 3, June 2026.
Abstract Calcium silicate‐based and glass ionomer cements are often used in caries‐affected dentine. This study investigated the remineralising and physicochemical properties of two calcium silicates and a glass ionomer cement. Human molars with Class I cavities were subjected to pH cycling to simulate caries lesions.

An Economical Bioprocess for Lipopeptide Production From Bacillus subtilis [PDF]

open access: yesMicrobiologyOpen, Volume 15, Issue 3, June 2026.
The lipopeptide (LP) production potential of Bacillus isolates was evaluated against phytopathogenic fungi, with B. subtilis 4‐Ka‐22 identified as the top‐performing strain. Optimization of the production medium—comprising molasses, soybean meal, CaCl2, and glycerol—resulted in a 13.4‐fold increase in cell growth and over 99% cost reduction compared to
