Impact of Environmental Microparticles on Insect Olfaction

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

An Exercise‐Pollution Exposure Index for Assessing Inhaled Heavy Metal Exposure Along Urban Walking Routes

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Urban walking routes are promoted as health‐supportive environments, yet they may also act as microenvironments of pollutant exposure during physical activity. This study evaluated heavy metal exposure along urban walking routes by integrating road dust metal concentrations, conventional health risk assessment, deposited inhalation dose, and ...

A study of airborne wear particles generated from organic railway brake pads and brake discs [PDF]

open access: yes, 2011
Brake pads on wheel-mounted disc brakes are often used in rail transport due to their good thermal properties and robustness. During braking, both the disc and the pads are worn.

Engineering Apprenticeships: Youth Transitions, Industrial Capital and the Role of Working‐Class Households

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT Using biographical methods, the study explores the lives of 34 young people undertaking engineering apprenticeships in Teesside, Northeast England. It examines why working‐class youth in a deindustrialised region might be attracted to engineering, how they might secure apprenticeship, and the invaluable role households play in orchestrating ...

A Digital Twin for Brake Wear Predictive Maintenance

open access: yesMathematical and Computational Applications
Brake pad wear is governed by coupled thermo-mechanical interactions in which degradation alters braking behaviour. This altered braking behaviour, in turn, affects vehicle dynamics, which, in turn, influences future wear evolution.
