Automatic detection of airborne pollen: an overview

traditionally been carried out using manual methods first developed in the early 1950s. Although this technique has been recently standardised, it suffers from several draw-backs, notably data usually only being ...

Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements

order to tackle this problem, a feasibility study based on a combination of chemometrics and multidimensional fingerprints recorded using chromatography was carried out.   Chromatographic fingerprints ...

COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS

fingerprints by performing a correlation analysis on the DAD data. Chemometric analysis was carried out using two approaches: 1. binary models for each plant separately and 2. multiclass models. The data were ...

Development of a Droplet Digital PCR to Monitor SARS-CoV-2 Omicron Variant BA.2 in Wastewater Samples

applicability of the proposed RT-ddPCR method was evaluated to monitor and quantify the emergence of the BA.2 variant over time. To validate this assay as a proof of concept, the measurement of the proportion of ...

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

daily temperature, respectively, with the minimum mortality temperature. For cold, we cumulated the risk over lags of 0 to 28 days before death and 0 to 7 days for heat. We carried out stratified analyses ...

Validity of self-reported air pollution annoyance to assess long-term exposure to air pollutants in Belgium
