levels (low, medium or high depending on number of correct answers) and scores for perceptions, self-efficacy, cues to action and preventive measures. Results We included 776 participants (62% females), of ...
Multidimensional chromatographic fingerprinting combined with chemometrics for the identification of regulated plants in suspicious plant food supplements
× time points) were used for selection of orthogonal wavelengths by conducting a correlation analysis. After preparation of triturations, recording of the fingerprints and creation of datasets (corrected ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
corrected for time shifts using correlation optimized warping and further pretreated using classical techniques like signal noise variate, autoscaling and derivatives), before being subjected to partial least ...
Spectroscopic approaches for conformity analysis of e-liquids
modelling. Next to baseline correction, classical preprocessing techniques like standard normal variate (SNV), derivatives and scaling were explored. In a first step, supervised modelling, using partial least ...
Validity of self-reported data to assess the prevalence of overweight, hypertension and cholesterol
the agreement between SR and measured overweight, hypertension and high cholesterol and to provide information to do a valid correction for measurement error. Methods The BHIS / BHES 2018 database was ...
Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
Score plot of the PC1, PC2 and PC3 of spectra pretreated. Samples with >0.2% THC in red and blue and sample with < 0.2% THC in green. The SIMCA classification model has a correct classification rate ...
Characterization and risk identification of falsified medicines and adulterated dietary supplements
medicines is not enough to evaluate their risk and that a broader characterization of the products is necessary for a correct risk evaluation. In another part of the project an onsite infrared based approach ...
Bepaling van spoorelementen in diverse matrices met spectrometische technieken.
very little concentration in organisms and environment. Trace elements can be divided in two categories, the essential trace elements, which are necessary in correct concentrations for the proper ...
DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS
time of 12 minutes was developed and optimized for both identification and quantification of the leachables. Matrix effects were corrected by using matrix-matched calibration and methyl cinnamate was ...
Comparative dissolution study on substandard and falsified antibiotics encountered in Belgium
parameters of drug quality control [2]. In this context, SF antimicrobials containing the correct dosage of claimed API s can exhibit poor dissolution performance. Thus, it is necessary and crucial to execute ...
