The analytical performance of the DAX, a high-throughput random access analyser, was studied according to ECCLS guidelines (ECCLS Document Vol. 3, No. 2, Beuth Verlag, Berlin, 1986) in a multicentre evaluation involving four laboratories. The trial took about 4 months. Determinations of 12 analytes produced more than 60,000 data. The imprecision study on 3(More)
Whole blood, hair and fingernails of 80 representative subjects from the Province of Rome were analysed for total mercury. The mean value for whole blood was 0.020 mg/kg, for hair 0.51 mg/kg and for nails 1.08 mg/kg. Correlations were found (except for hair) between mercury levels and the number of fish meals, mercury amalgam dental fillings and residence(More)
The morphological organization of the structural components in the dog carotid wall is investigated by X-ray diffraction and microscopic analysis. Histological analysis confirms an anisotropic morphology of smooth muscle cells and elastic fibers in the tissue. Collagen fibers, as revealed by X-ray diffraction technique, are organized in an isotropic network(More)
The ideal computerized mammogram processing system still needs to be developed. In order to achieve maximum flexibility we suggest a modular scheme, dividing the processing sequence into functionally autonomous modules. This paper provides a general scheme for detection and/or automated recognition of microcalcifications. Some modules that perform ROI(More)
Pb-blood levels of 801 adult non-occupationally exposed subjects from Rome are reported. The investigation was carried out according to EEC Directive No. 77/312 with acceptable quality control of analytical data. A mean Pb-blood level of 173 micrograms/l (198 micrograms/l for males and 150 micrograms/l for females) was found; good correlations were found(More)
