Failure Risk Assessment of Surge Arrester Using Paralleled Spark Gap

IEEE Access, 2020
Surge arresters are usually used to protect distribution feeders against randomly distributed lightning overvoltages. However, there is a probability of surge arrester failure due to an increase in its absorbed energy over the withstand capability.

Treatment barriers and gender‐based perceptions: Establishing gender‐based treatment specialty facilities as a strategy to motivate South African young women to seek treatment for substance use disorders

Journal of Community Psychology, Volume 51, Issue 1, Page 182-200, January 2023., 2023
Abstract South Africa alongside other low‐middle‐income countries have been some of the hardest hit by the substance use scourge. The study sought to identify and measure treatment barriers among young adults (18–29 years) living with substance use disorders, and then examine the role of gender in the perception of treatment barriers, with a view to ...

The effects of endocrine‐disrupting chemicals on ovarian‐ and ovulation‐related fertility outcomes

Molecular Reproduction and Development, Volume 89, Issue 12, Page 608-631, December 2022., 2022
Abstract Exposure to endocrine‐disrupting chemicals (EDCs) is unavoidable, which represents a public health concern given the ability of EDCs to target the ovary. However, there is a large gap in the knowledge about the impact of EDCs on ovarian function, including the process of ovulation.

Application of Deep Learning and Symmetrized Dot Pattern to Detect Surge Arrester Status

Applied Sciences, 2022
Surge arresters primarily restrain lightning and switch surges in the power system to avoid damaging power equipment. When a surge arrester fails, it leads to huge damage to the power equipment.
