Traditional newborn dried blood spot screening (NDBS) has expanded in recent years to include upwards of 50 different conditions in many states. Once the screening tests are complete, the residual blood specimens (RBSs) that remain are most often available for quality assurance and public health research. The articles by Botkin et al1 and Bombard et al2 contained in this issue of Pediatrics inv...

The effect of sodium dodecylsulphate (SDS), sodium alkilbenzenesulphonate (ABSNa) and sulphosuccinates IOP5 and N5, present in different concentrations, on the kinetics of desulfurication conducted with the use of Desulfotomaculum ruminis bacteria was analysed. As follows from the determined activity of the microorganisms, the presence of SDS and ABSNa inhibits the process of desulfurication. T...

This study was designed to determine the effects of five different salinity levels (25, 30, 35, 40 and 45 ppt) on survival rate Farfantepenaeus aztecus larvae from Nauplius5 post-larvae1 (N5-PL1). For this purpose, 50 that reached N5 stage were stocked in 2-L round bottom glass flasks replications grown up PL1 at 27.6±0.4°C. At end study, as highest (44.00±23.15) protozoal stages obtained 35 pp...

Downey and Lempp 8] have shown that the contiguous computably enumerable (c.e.) degrees, i.e. the c.e. Turing degrees containing only one c.e. weak truth-table degree, can be characterized by a local distributivity property. Here we extend their result by showing that a c.e. degree a is noncontiguous if and only if there is an embedding of the nonmodular 5-element lattice N5 into the c.e. degre...

We investigate the noise sensitivity of top eigenvector a sparse random symmetric matrix. Let v be an N×N matrix with average d non-zero centered entries per row. resample k randomly chosen and obtain another realization v[k]. Building on recent results matrices analysis previously developed for Wigner matrices, we prove that, if d?N2?9, high probability, when k?N5?3, vectors v[k] are almost co...

An n-vertex graph G is c-Ramsey if it contains neither a complete nor an empty induced subgraph of size greater than c log n. Erdős, Faudree and Sós conjectured that every c-Ramsey graph with n vertices contains Ω(n5/2) induced subgraphs any two of which differ either in the number of vertices or in the number of edges, i.e. the number of distinct pairs (|V (H)|, |E(H)|), as H ranges over all i...

The quantity N5(n) is the maximum length of a finite sequence over n symbols which has no two identical consecutive elements and no 5-term alternating subsequence. Improving the constant factor in the previous bounds of Hart and Sharir, and of Sharir and Agarwal, we prove that N5(n) < 2nα(n) +O(nα(n) ), where α(n) is the inverse to the Ackermann function. Quantities Ns(n) can be generalized and...
