Purpose: To evaluate the population variation in head-to-helmet contact forces in helmet users.
Methods: Four different size Kevlar composite helmets were instrumented with contact pressure sensors and chinstrap tension meters. A total number of 89 volunteers (25 female and 64 male volunteers) participated in the study.

Since the Industrial Revolution, anthropogenic activities have substantially increased the input of nitrogen (N) and phosphorus (P) into river watersheds, exacerbated by uncertainties stemming from climate change. This study provided a detailed analysis of N and P inputs within the Dawen River Watershed in China from 2000 to 2021. The Net Anthropogenic Nitrogen Input (NANI) and Net Anthropogenic Phosphorus Input (NAPI) methods were used in study, which aimed to investigate how they respond to various climate change factors.

Resorcinol is a widespread substance used in a large variety of manufacturing industries, including cosmetics, with endocrine-disrupting activity on the thyroid function. The aim of the present study was to develop and validate a sensitive, selective and robust method to quantify resorcinol in urine and thereby assess hairdressers' occupational exposure. As resorcinol is mainly excreted in urine as glucuronide or sulfate forms, the first step consisted in hydrolyzing urine samples with a β-glucuronidase-arylsulfatase enzyme for 16 h.

Biomimetic patterning emerges as a promising antibiotic-free approach to protect medical devices from bacterial adhesion and biofilm formation. The main advantage of this approach lies in its simplicity and scalability for industrial applications. In this study, we employ it to produce antibacterial coatings based on silicone materials, widely used in the healthcare industry.
