Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
material Abstract: An approach for the size measurement of particulate (nano)materials by transmission electron microscopy was evaluated. The approach combines standard operating procedures for specimen ...
Scientific opinion on the proposed amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of additional parameters related to its particle size distribution
in the EU specifications for E 171 a specification of more than 100 nm for median Feret min diameter and less than 50% of the number of constituent particles below 100 nm; measured by EM in both cases. ...
Bordetella pertussis seroprevalence in Belgian adults aged 20-39 years, 201234005
30-39 years age group. Anti- PT IgG levels were measured using Virion-Serion ELISA and analysed using predefined cut-off levels. Sixty-one (4%) sera were indicative of an infection in the past 2 years ...
Educational inequalities in leisure-time physical activity in 15 European countries.
(PRR s). The PRR measured the risk of showing a low level of LTPA for a given educational level, relative to the highest educational group. RESULTS: Within Europe, large cross-national differences in the ...
Association of physical activity, waist circumference and body mass index with subjective health among Belgian adults.
general health, subjective health, lifestyle and PA was completed. Weight and height were self-reported, and WC was measured in orthostatic position. PA was assessed by the short International PA ...
Increasing the Vaccine Potential of Live M. bovis BCG by Coadministration with Plasmid DNA Encoding a Tuberculosis Prototype Antigen.
B-cell responses were observed with this protocol in C57BL /6 mice when compared to the administration of only BCG or in combination with an empty pDNA vector, as measured by Th1-type spleen cell cytokine ...
Hair mercury and urinary cadmium levels in Belgian children and their mothers within the framework of the COPHES/DEMOCOPHES projects.
set up within the frame of the European projects DEMOCOPHES and COPHES. In 17 European countries, biomarkers of some environmental pollutants, including urinary cadmium and hair mercury, were measured ...
Molecular epidemiological analysis of the transboundary transmission of 2003 highly pathogenic avian influenza H7N7 outbreaks between the Netherlands and Belgium.
distance contacts within Belgium or whether this farm presented a fourth independent transboundary introduction. These multiple transnational transmissions of HPAI in spite of reinforced biosecurity measures ...
Quantifying burden of disease to support public health policy in Belgium: opportunities and constraints
the most important summary measure of public health. DALY s quantify the number of healthy life years lost due to morbidity and mortality, and thereby facilitate the comparison of the relative impact of ...
