Performance improvement of MO surge arrester using high gradient arrester block against VFTOs [PDF]
, 2019 It is well known that the metal oxide surge arrester is inoperative against very fast transients overvoltages (VFTOs) because of its strong stray capacitive effect.

Design of a Lightning Protection System for an Overhead 3 kV DC Electrified Railway Line: A Case Study from South Africa [PDF]
, 2021 A protection scheme is proposed for the 3 kV DC railway, in Kwa-Zulu Natal province, a region with a high lightning occurrence density. The surge protection was sought by implementing three metal-oxide surge arresters and an overhead ground wire.

Will Listing Rule Reform Deliver Strong Public Markets for the UK?
The Modern Law Review, Volume 86, Issue 1, Page 176-213, January 2023., 2023 There is a general consensus that the UK needs strong public equity markets. To help to ensure Britain is well‐positioned on this front, the Financial Conduct Authority reformed the London Stock Exchange's listing regime in 2021 to foster initial public offerings (IPOs).

State of the Field: The Modern History of Childhood
History, Volume 107, Issue 378, Page 949-964, December 2022., 2022 Abstract This state of the field article presents three questions for students and scholars of childhood: first, who is included in the history of childhood? Second, why does the history of childhood matter? Third, how should we do the history of childhood? It argues that all historians of childhood need to reflect upon modern developmental concepts of

A closer look at arrested spinodal decomposition in protein solutions [PDF]
J. Phys.: Condens. Matter 21 (2009) 32220, 2009 Concentrated aqueous solutions of the protein lysozyme undergo a liquid solid transition upon a temperature quench into the unstable spinodal region below a characteristic arrest temperature of Tf=15C. We use video microscopy and ultra-small angle light scattering in order to investigate the arrested structures as a function of initial concentration ...
