Data sharing agreements

If a substance is not listed in EINECS and not included in the scope of the DSD, it is considered to be new and a prospective EU supplier has to notify it, unless an exemption applies, as discussed below. It is also possible that the substance has already been notified and there is an obligation to make a data-sharing enquiry (DSE) to find out it there is another notification already in place. The aim of the exercise is to reach an agreement to share the notification studies, in the interests of animal welfare. Some countries make data sharing mandatory for animal studies. 

Fig. A1.3. Comparison between observed abundances and abundances predicted by the theory of primordial nucleosynthesis. The horizontal axis shows the ratio r between the number of baryons and the number of photons. The vertical axis shows the mass fraction of helium and the numerical ratios D/H, He/H and li/H. Observational data are represented by boxes with height equal to the error bar. In the case of helium and lithium, there are two boxes, indicating the divergence between different observers. Deuterium holds the key to the mystery, but it is difficult to measure. The region of agreement is shown as a shaded vertical ribbon (after Buries Tytler 1997). A higher level of deuterium would lead to a lower baryonic density, of the order of 2%. This would agree better with the lithium data, which have been remarkably finely established. This idea is supported by E. Vangioni-Flam and shared by myself. (From Tytler 1997.)...

Other research activities related to residential exposure assessment currently being sponsored by the USEPA include the National Human Exposure Assessment Survey (NHEXAS) (website http //www.epa.gov/heasd/edrb/nhexas.htm). In addition, the USEPA concluded a Co-operative Agreement, referred to as the Residential Exposure Assessment Project (REAP) with the Society for Risk Analysis (SRA) and the International Society of Exposure Analysis (ISEA) which resulted in a reference textbook (Baker et al, 2001) describing relevant methodologies, data sources and research needs for residential exposure assessment. The REAP and other efforts complement other USEPA initiatives, such as the development of the Series 875 guidelines, and will facilitate a sharing of information and other resources between the USEPA, other Federal and State agencies, industry, academia and other interested parties. 

Common approaches for evaluation of submitted data are important prerequisites to full harmonization. With agreement on the methodology for conduct of occupational and residential exposure assessments, harmonized approaches for regulatory interpretation of the data become important to review sharing. 

The same molecular orientation is found for CO on Cu(lOO) but on Cu(lll) an inclination of 35" from the normal has been suggested, this time on the basis of ARUPS data. Agreement with the theoretical calculations was not entirely satisfactory, however, and it may be that, in this case, the 4adsorption bond, undergoes indirect changes following adsorption by way of atomic orbitals it shares with the 5[Pg.53]
