CD4+ cell count (Epics XL-MCL, Beckman Coulter, Brea, CA, USA) and HIV-RNA determination (branched-DNA version 3.0 assay, Siemens Diagnostics, Deerfield, IL, USA) were performed every 6 months after delivery.
Solution and melt 13C NMR has been established as a useful tool for a quantitative determination of branch content of short- and long-chain branched polyethylenes while XRD can reveal important information on the morphology, structure and the degree of crystallinity of polythene [6, 7, 8].
In the present paper we report the synthesis of high molecular weight polyethylene using Zr-based single site catalyst and results of the use of melt-state 13C MAS NMR and X-ray diffraction techniques for the determination of branch content of long-chain polyethylene's and their crystal structure.
Thus, our results suggest that Crk and CrkL, as well as Reelin signaling, are not essential for determination of branch angle and the segment length during dendritogenesis.
In contrast to LD-grown buds, cell division in internodes of SD buds is more disorganized and ceases soon after determination of branch crown identity.
The fault detection, parent bus identification, determination of faulty branch relays to be supervised and fault classification methods remain same as described in the preceding section.
Furthermore, it should also be noted that the presence of re-entrant connections invalidates the standard theory of branching processes [20], and makes a rigorous determination of the branching parameter σ problematic if not impossible, e.g., in the presence of avalanches merging.
Judges, he said, must give executive branch determinations "utmost deference".
Some expressed worry about second-guessing executive branch determinations about who should be allowed to enter the United States.
This root-and-branch determination turned what might have been a noble, if controversial, vehicle for intelligence reform into something destructive.
