Wind-Induced Response and Its Controlling of Long-Span Cross-Rope Suspension Transmission Line

open access: yesApplied Sciences, 2022
In mountainous areas, the installation of steel towers was the major obstacle to the construction of transmission lines. In long-span cross-rope suspension (CRS) structures, the conductors are supported by hundreds-meters-long suspension cables crossing ...

Study on the Maximum Ice-Shedding Height of Conductor Based on Energy Method

open access: yesIEEE Access, 2023
Ice shedding of transmission lines may lead to interphase flashover and thereby endanger power transmission. The ice shedding of transmission lines is essentially an energy conversion process.

Wind Tunnel Test Investigation on Unsteady Aerodynamic Coefficients of Iced 4-Bundle Conductors

open access: yesAdvances in Civil Engineering, 2019
Iced conductor motion is induced by the aerodynamic instability of these conductors. The unsteady aerodynamic characteristics are different from the steady aerodynamic characteristics.

Investigation on Stability and Galloping Characteristics of Iced Quad Bundle Conductor

open access: yesJournal of Applied Fluid Mechanics, 2021
The stability and galloping characteristics of iced quad bundle conductor are studied in this paper. Firstly, the aerodynamic coefficients of iced quad bundle conductor and single conductor under four different working conditions are obtained by wind ...

Experimental study on self-excited vibration of artificial imitation ice for real transmission lines [PDF]

open access: yesAIP Advances
This paper proposes a selection method for artificial imitation ice. Using computational fluid dynamics simulations, the lift and drag coefficients of D-shaped, sector-shaped, and crescent-shaped iced conductor sections applicable to test lines were ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Ice shedding from cables and conductors : [PDF]

open access: yes, 2007
Le givrage atmospherique est a la source de serieux problemes d'origine electrique et mecanique sur les reseaux de transport et de distribution de l'energie electrique. Le delestage naturel de glace de câbles et conducteurs, une consequence du givrage atmospherique, est a la source de nombreux problemes, d'ou la necessite de l'etude de la rupture ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
