Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

open access: yesPhotochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Width distribution of contact lines on a disordered substrate

open access: yes, 2003
We have studied the roughness of a contact line of a liquid meniscus on a disordered substrate by measuring its width distribution. The comparison between the measured width distribution and the width distribution calculated in previous works, extended ...

Informal Firms' Adoption and Use of Mobile Money Under Uncertain Times: Evidence From Burkina Faso

open access: yesReview of Development Economics, EarlyView.
ABSTRACT This paper investigates how uncertainty affects mobile money adoption and use by informal businesses. Despite the prevalence of the informal sector in developing countries and the recognized potential of mobile money for financial inclusion, empirical research on its adoption and usage among unregistered businesses is limited.

Endothelial‐to‐mesenchymal transition in the fetoplacental macrovasculature and microvasculature in pregnancies complicated by gestational diabetes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Transforming growth factor (TGF)‐β2 and interleukin (IL)‐1β induced morphological and molecular changes consistent with endothelial‐to‐mesenchymal transition (EndMT) in HUVECs isolated from both pregnancies complicated by gestational diabetes (GDM) and non‐GDM pregnancies.

Glucose and fructose contributions to exogenous carbohydrate oxidation and performance at moderate altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Co‐ingesting fructose with glucose increases exogenous carbohydrate oxidation at sea level, but its effect at altitude is unclear. This study compared glucose–fructose (GLU–FRU), glucose alone (GLU) and placebo during 120 min of running at 70% V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$ at 2500 m in eight males.
