Wildland–urban interface expansion: Towards comprehensive planning processes

open access: yesPeople and Nature, EarlyView.
Abstract Wildland–urban interface (WUI) expansion is accelerating in numerous regions around the world due to increasing amenity‐led migration processes, defined as the movement of people seeking higher environmental quality. While WUI areas are complex social–ecological systems requiring holistic planning and management, they are usually approached ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Propulsive Power in Cross-Country Skiing: Application and Limitations of a Novel Wearable Sensor-Based Method During Roller Skiing

open access: yesFrontiers in Physiology, 2018
Cross-country skiing is an endurance sport that requires extremely high maximal aerobic power. Due to downhill sections where the athletes can recover, skiers must also have the ability to perform repeated efforts where metabolic power substantially ...

Functional Design Employing Miniaturized Electronics with Wireless Signal Provision to a Smartphone for a Strain-Based Measuring System for Ski Poles

open access: yesComputers, 2021
The individual monitoring of cross-country skiers’ technique-related parameters is crucial to identifying possible athlete-individual deficits that need to be corrected in order to optimize the athlete’s performance in competition.

Modeling Oxygen Uptake during V1 Treadmill Roller Skiing [PDF]

open access: yes, 2009
The use of regression equations to predict oxygen uptake in relation to speed, grade, power output, and anthropometric characteristics is common in cardiac rehabilitation and athlete fitness testing.

Classification of Fog Life‐Cycle Phases Using Ground‐Based and Satellite‐Based Observations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the life‐cycle phases of radiation fog events—formation, maturity, and dissipation—are automatically classified at a ground station in Southwest Germany based on visibility trends and thresholds. We demonstrate that visibility detects radiation fog phases effectively, while its combination with ceilometer data can detect the life‐cycle ...

Choice of Pole and Ski Lengths Among Elite Cross-Country Skiers: The Influence of Sex and Performance Level

open access: yesFrontiers in Sports and Active Living, 2021
Cross-country (XC) skiers employ whole-body exercise to generate speed through poles and skis. The choice of optimal pole and ski lengths are therefore of high importance.

Heat stress in tropical highland regions: the case of Kenya during February 2024

open access: yesWeather, EarlyView.
Understanding and awareness about heat stress remain low in sub‐Saharan countries despite high exposure and vulnerability. After the national media in Kenya reported that people had complained about unusual heat stress during February 2024, we combine in situ and reanalysis data to (i) put this event into climatological perspective, and (ii) give ...

Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

open access: yesWildlife Biology, EarlyView.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...
