Inter-correlations lowest

Assay Development and Validation. Reproducibility of this ELISA assay was determined based on a set of clomazone standards that were run on different plates on the same day (intra-assay) and on different days (inter-assay). The intra-assay coefficient of variation of the standards changed from 1.5 at the highest clomazone concentration (250 ppb) to 22 at the lowest concentration of 1.4 ppb. The coefficient of variation(CV) at clomazone rate of 12.5 ppb was 10. Similar values were obtained for the inter-assay variability, with the CV of the 1.4 ppb concentration being 22.5, and the CV for the 250 ppb concentration being 2.7. The CV for the 10 ppb concentration of clomazone was about 5 between tests. Analysis of the data for this range of clomazone concentrations indicates that there is good correlation (r =0.97) between the log of the concentration of clomazone and percent inhibition in the assay when the linear regression equation was used. Based on these results, the limit of the test s sensitivity was defined as 2 ppb (10 ppb in soil) and the limit of detection was set at 1 ppb. [Pg.173]

Qualitatively, there is a correlation between such a lattice anisotropy and the spatial distribution of intermolecular contacts. In the case of [Fe(phen)2(NCS)2], the lowest values of linear compressibility, which are associated with the stiffest lattice directions, concern axes a and b these correspond to intrasheet directions in which many intermolecular contacts are observed on the other hand, is larger than ka and k), and corresponds to the intersheet direction for which many fewer contacts are observed. In the case of [Fe(btz)2(NCS)2], the proportion of inter- and intrasheet... [Pg.67]

In the strongly-correlated limit, when the electron delocalization (i.e. the tpq terms) becomes smaller than the electron repulsion U, an appropriate description of the lowest states is provided by the neutral VB determinants only, i.e. those in which each carbon p bears one unpaired electron in its n atomic orbital (AO, hereafter labelled 5 ). The n electron systems behaves as a pure spin system, obeying a Heisenberg Hamiltonian [22,23]. The inter-atomic delocalization, i.e. the interaction between the neutral VB distributions and the ionic ones, results in an antiferromagnetic spin coupling on each bond. One of the below-discussed rules, known as the Ovchinnikov s mle [21], has been derived from this magnetic approach. Numerous works [24] have shown the relevance of magnetic descriptions... [Pg.363]
