Effects of Exposure to Radiation and Steam on Silicone Rubber Cables Removed From a Nuclear Power Plant

High Voltage, EarlyView.
ABSTRACT Low‐voltage cables insulated with silicone rubber were harvested from three locations in the primary containment vessel of a boiling water nuclear power plant (NPP). Subsequently, the cable, which was placed in an ambient environment with a relatively higher temperature and the highest rate, was cut into four shorter ones.

Basophil Activation Test as Biomarker of Severity and Threshold of Allergic Reactions to Cow's Milk During Oral Food Challenges

Allergy, EarlyView.
The threshold of reactivity during fresh milk challenges was 70% lower than that of baked milk challenges, reflecting the higher allergenicity of fresh milk. BAT was the only biomarker statistically significantly different between severity and threshold groups, for baked milk and fresh milk allergies, respectively.

The influence of a cooling water system on waterbird habitat use in a coastal environment

Ibis, EarlyView.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.

Intelligent online process fault diagnosis through integrating Andrews function, autoencoder, and neural networks

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 2033-2054, April 2026.
Abstract This paper proposes an online process fault diagnosis scheme that integrates principal component analysis, Andrews function, autoencoder, and multilayer feedforward neural network to enhance the fault diagnosis performance. Useful features are extracted from the online monitoring data by using Andrews function (also known as Andrews plot).
