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

High 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

Benzalkonium Chloride in Eye Drops Causing Allergic Contact Dermatitis: A Case Series

Australasian Journal of Dermatology, EarlyView.
ABSTRACT We present three patients who developed allergic contact dermatitis (ACD) from benzalkonium chloride (BAK) in ophthalmic drops. BAK is a preservative commonly found in ophthalmic formulations and there is a rising trend of ACD to this allergen. The irritant and sensitising properties of BAK on the ocular mucosa will be discussed.
