Effects of tree pollen on throughfall element fluxes in European forests

linear mixed-effects modelling (LME). TF was measured in 1990–2018 during the main pollen season (MPS, arbitrary two months) in 61 managed, mostly pure, even-aged Fagus, Quercus, Pinus, and Picea stands ...

Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS

extracted with methanol 80%, followed by an SPE clean-up step before LC- MS / MS analysis. The LOQ was fixed at 1 µg/L for the nine cyanotoxins and 0.05 µg/L for AFM1. Recoveries were measured between 82.67% ...

Quality control and correction method for air temperature data from a citizen science weather station network in Leuven, Belgium

on these intra-urban weather patterns, dense high-quality atmospheric measurements are needed. Crowdsourced weather stations (CWS s) could be a promising solution to realise such monitoring networks in ...

Association between temperature and natural mortality in Belgium: Effect modification by individual characteristics and residential environment

PM2.5 and NO2  while for O3, the effect was lower. Conclusions These findings allow for targeted planning of public-health measures aiming to prevent the effects of extreme temperatures. Health Topics:  ...

Higher buccal mtDNA content is associated with residential surrounding green in a panel study of primary school children

sensing derived map. Given the repeated measures design, we applied a mixed-effects model with school and subject as random effect while adjusting for a priori chosen fixed covariates. Results: mtDNAc was assessed ...

What triggers selective daily mobility among older adults? A study comparing trip and environmental characteristics between observed path and shortest path.

older adults (aged 67-94) living in urban and suburban areas of Luxembourg, was measured through detour percentage between their observed GPS-based paths and their shortest paths. Multilevel negative ...

Changes in physical activity by context and residential greenness among recent retirees: Longitudinal GPS and accelerometer study.

Place, Volume 73 (2021) Abstract: This study examined the changes in accelerometer-measured physical activity by GPS-measured contexts among Finnish retirees (n = 45 (537 measurement days)) participating ...

Converting Raw Accelerometer Data to Activity Counts Using Open-Source Code: Implementing a MATLAB Code in Python and R, and Comparing the Results to ActiLife

Publication Type: Peer reviewed scientific article Authors: Ruben Brondeel; Yan Kestens; Javad Rahimipour Anaraki; Kevin Stanley; Thierry, Benoit; Daniel Fuller Source: Journal for the Measurement ...

4DEMON: Integrating 40 Years of Data on PCB and Metal Contamination in Marine Sediments of the Belgian Part of the North Sea

different grain size fractions were analyzed, appropriate co-factors were not always analyzed, and measurement uncertainties were not always indicated. These issues hampered the use of readily available, ...
