Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
agglomeration state. The measurement of the median value of the minimal external particle diameter distribution was intra-laboratory validated. The validation study included an assessment of the limit of ...
Biological activity conferred by endocrine disrupting chemicals in hospital effluent and river water from the Brussels Region, Belgium
assess endocrine activity by comparing the mixture or cocktail effect originating from the sample extract. Added value is that this technique picks up effects from compounds that are not ...
50 Hz electric and magnetic fields and health: which message to the public?
uncertainty raises numerous questions. In this paper, significant key concepts are described to better understand the potential effects of electric and magnetic fields on health. Everyday life exposure values ...
Identification of filamentous fungi isolates by MALDI-TOF mass spectrometry: clinical evaluation of an extended reference spectra library.
identification method based on morphological observations. The use of MALDI- TOF MS resulted in the correct identification of 95.4% of the isolates at species level, without considering LogScore values. Taking ...
