2. Contribution to the study of the application of alternative materials in the composites based on Portland cement : use of polypropylene grains recycled in substitution to the aggregates of the concrete / Contribuição ao estudo da aplicação de materiais alternativos nos compositos a base de cimento Portland : uso de grãos de polipropileno reciclado em substituição aos agregados do concreto
The main objective of this dissertation was the determination of the main mechanical properties of a composite based on Portland cement CP-V-ARI (high initial resistance) tends as aggregate the grains recycled agglutinated of polypropylene (GRAP). The choice of the plastic is due to the fact that it is one of the main materials used by the industry in genera

3. Occupational lead exposure in Denmark: screening with the haematofluorometer.
The zinc protoporphyrin/haemoglobin (ZPP/Hb) ratio was measured in the field with a haematofluorometer. A significant increase in ZPP/Hb ratio with advancing age was found in 1295 men who denied any excess exposure to lead. Ninety-seven per cent of the results were below 110 mumol ZPP/mol Hb(Fe) (4.4 microgram ZPP/g Hb). The ZPP/Hb ratio was determined in a
