To examine individual changes in the PRR across shorter time periods, boatwhistles from individuals were tracked for 5 hours (n = 6 fish; all boatwhistles) and 36 hours (n = 1 fish; first 5 boatwhistles per hour) and compared to changes in temperature.
IP parser is initially deployed in an active PRR and is processing the current data flow.
After the 8th quarter, the main determinants of the change in ppi are gap with 37% and rmir with 25% while ppi and prr have approximately equivalent effect with 19%.
Based on a review of existing studies, this section has discussed the gendered dimension of the FN ideology, policy and membership, indicating that, under its former leader, the party was a highly 'masculinised' PRR political organisation: it expressed overtly sexist views and supported highly conservative ('traditional') policies in the matter of gender--even if its positions softened over the years.

In Figures 1 and 2, comparison between the theoretical and experimental removed depth of AISI1012 and AISI1005 samples at different peak power ([P.sub.p]) and pulse repetition rate (PRR), respectively, was shown for both wavelengths 1064 nm and 532 nm.
Previous studies showed that HCV proteins produced in infected cells impair the PRR signaling involved in IFN-[beta] production via cleavage of TRIF and IPS-1 [3-5] and further impair downstream IFN action in various ways [6].
All the parameters except for [B.sub.n] and C/N0 are constants for a specific GPS receiver, so if C/N0 decreases, [B.sub.n] has to decrease accordingly to constrain PRR error within a certain level.
The regulations merely repeat this conditional requirement without elaboration ([section] 300.320[a][4]), but the comments accompanying the regulations explained that peer-reviewed research (PRR) "generally refers to research that is reviewed by qualified and independent reviewers to ensure that the quality of the information meets the standards of the field before the research is published" (IDEA Final Regulations Commentary, p.
