Comprehensive Analysis of Winding Electromagnetic Force and Deformation During No-Load Closing and Short-Circuiting of Power Transformers

open access: yesIEEE Access, 2021
When an electromagnetic transient occurs in a transformer, certain parts of the winding will be over stressed internally, which in severe cases will lead to the destruction of the winding insulation.

Modeling of a Power Transformer Winding for Deformation Detection Based on Frequency Response Analysis * [PDF]

open access: yes, 2020
: The paper presents a mathematical model of disc-type power transformer winding for frequency response analysis (FRA) based on traveling wave and multiconductor transmission line theories. Each disc of the model is described by traveling wave equations,

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Dynamic optical deformation measurements on wind turbines

open access: yesJournal of Physics: Conference Series, 2022
Abstract Because of an increase in the size of wind turbines in recent years, efficient structural health monitoring of the turbine’s structure has become critical. Wind turbine towers deform elastically as a result of the loads due to wind and inertial forces acting on the revolving rotor blades. To adequately assess these deformations,

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Calculation and Analysis of Rotor Thermal Static Field for Inter-Turn Short Circuit of Large Hydro-Generator Excitation Winding

open access: yesEnergies, 2019
Rotor winding inter-turn short circuit a common fault in hydro-generators. This fault would change the temperature, stress, and other thermal fields of a rotor and threaten the safe operation of the generator.
