PRP-A showed a significantly (p = 0.001) lower PLT concentration when compared to whole blood and PRP-C and a higher concentration in comparison to PRPB
and PRP-D, in which PLT counts were similar (Figure 2).
Some authors (Bierschenk (43), Dickovick (44), for instance) stated that Kerekou' politics of integration into PRPB
of population along with a de-ethnicisation beyond ethnic lines, was a good thing for this mobilization and made it possible.
The limits of detection (LODs) in a 0.1[micro]/L urine sample were 0.4 [micro]g/L (BPA and BP-3), 0.2 [micro]g/L (PrPB), 1.0 [micro]g/L (MePB), and 2.3 [micro]g/L (TCS).
BP-3 and MePB were detected in all participants, and PrPB was detected in all but one participant each week.
As expected, we observed no difference for MePB, PrPB, or TCS, although urinary concentrations of BP-3 were higher after polycarbonate bottle use.
(4) The main objective of the PRPB survey is to collect information about the volume and characteristics of travelers from Puerto Rico to the U.S.
According to the operational definition used by the PRPB for the ramp survey, an immigrant is a person 16 years or older who intends to stay in Puerto Rico for three months or longer.
Taken as a whole, the PRPB's Survey of Travelers was for many years the best source of information about Puerto Rico migrants' characteristics, and, because it is collected continuously, the survey allows for inter-temporal comparisons of such characteristics on a consistent basis.
The data for the first two periods is from the Survey of Travelers of the PRPB, and the last from the PRCS and the ACS.
(4) The PRPB uses two questionnaires to collect data, one for departures and one for arrivals.
The PRPB estimates of migratory flows are different from those of the Port Authority and can be adjusted to control for age or other characteristics.
