Dielectric Breakdown Characteristics of Biaxially Oriented Polypropylene Films: Surface Structures on Thickness Dependence

High Voltage, EarlyView.
ABSTRACT Film capacitors, essential for energy storage in power systems, benefit from reduced film thickness to increase capacitance and lower costs. While the inverse power law traditionally links higher electric strength with thinner films, its validity diminishes below a critical thickness.

Investigating Dynamic Characteristics of Cavitation in Insulating Oil Microgaps Under Vibration: Theoretical Analysis and Experimental Observation

High Voltage, EarlyView.
ABSTRACT The internal pressure fluctuations caused by vibration in oil‐immersed electrical equipment can initiate bubbles within narrow oil gaps, reducing the electrical strength of equipment and giving rise to the problem of abnormal gas production in oil‐immersed equipment.

The Paediatric BCG Vaccine Century: From Historical Success to Future Innovations

Acta Paediatrica, EarlyView.
ABSTRACT Aim The tuberculosis (TB) vaccine, Bacille‐Calmette‐Guérin (BCG), protects infants against severe forms of primary TB. Yet, it does not protect against pulmonary reactivation TB in adults. Methods A literature review was conducted between 1st January and 28th February 2025 using PubMed, Google Scholar and reports of the World Health ...

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

Acta Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...
