Tribolectric charging results from contact between surfaces, but precisely what is meant by
each is not defined or understood, as they relate to charging. The recent microscopic …

Meurig W. Williams hen two objects are brought into VV contact and then separated, elec trical
charges are generated at the sur faces. Such events are called triboelectric charges, also …

Whether charging of metal beads cascaded over inclined polymer films results from electron
or material exchange can be resolved by determining whether it is the surface roughness of …

Whether electrons or ions are involved in triboelectric charging of insulators remains elusive.
We designed polymers whose surface compositions (determined by X-ray photoelectron …

In a recent publication on the mechanisms of triboelectric charging of insulators we interpreted
our experimental results in terms of electron and ion transfer. We now report that these …

Background Validated risk equations are currently recommended to assess individuals to
determine those at ‘high risk’ of cardiovascular disease (CVD). However, there is no longer a …

Background Use of a validated risk-assessment tool to identify individuals at high risk of
developing type 2 diabetes is currently recommended. It is under-reported, however, whether a …

In February, 2013, a 39-year-old bilingual medical practitioner attended our hospital after
she developed difficulty expressing herself in English. She was a native Welsh speaker and …

This study concerns the ion containing terpolymers of styrene, n‐butylmethacrylate, and
potassium methacrylate (S/n‐BMA/K + MA − ) produced by the partial hydrolysis of random S/n‐…

Objective: To assess the prevalence of undiagnosed cardiovascular disease (CVD) in a cohort
of male steelworkers in South Wales, UK. Methods: Male steel industry workers (n= 221) …
