Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing

open access: yesHigh Voltage, EarlyView.
ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic

Sperm Mitochondrial DNA Copy Number and Nuclear DNA Methylation Across Clinical and Non‐Clinical Preconception Cohorts

open access: yesAndrology, EarlyView.
ABSTRACT Background Sperm mitochondrial DNA copy number is an emerging marker of male fertility, with elevated mtDNAcn associated with poor semen quality across various populations. Sperm DNA methylation has also been previously demonstrated to be negatively correlated with semen parameters in IVF cohorts.

Basal body temperature as a biomarker of reproductive state in ewes: A multi‐method comparison

open access: yesAustralian Veterinary Journal, EarlyView.
This study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...
