Persistence. Despite challenges, the team persists in working toward the goals included in the wraparound plan until such time as the family has met their goals and/or are no longer requesting assistance from the ISST.
Persistence. All degradation results show that PFOA is persistent and does not undergo any abiotic or biotic degradation under relevant environmental conditions. According to Xxxxx XXXX (section 1.1.1), PFOA meets the criteria for being persistent (P) and very persistent (vP).
Persistence. Based on the available information from experimental and estimated data, CHR degrades very slowly in soil with half-lives of >180 d. Thus, the P and the vP criteria of REACH Annex XIII are fulfilled.

We wish to allow theories in which the binding to up hold rights is either one shot i e may only be exercised once or persistent for the duration of the commitment i e may be exercised an unlimited number of times while the agent is bound to uphold the agreement in which it is permitted Axioms and respectively express these two alternatives Done y a
Persistence. Teacher persists in seeking effective approaches for students who need help, using an extensive repertoire of strategies and soliciting additional resources for the school.
Persistence. The Member State Committee in its opinion3 concluded that: […] After the MSC and RAC opinion making processes, new studies have been published. The relevant studies have been summarised in the Support document to this agreement. This new information supports the earlier conclusion. The Member State Committee in its opinion3 concluded that: 2 ECHA (2015): Member State Committee’s Opinion on Persistency and bioaccumulation of Octamethylcyclotetrasiloxane (D4) (EC No: 000-000-0, CAS No: 556-67-2) and Decamethylcyclopentasiloxane (D5) (EC No. 000-000-0, CAS No. 541- 02-6). xxxxx://xxxx.xxxxxx.xx/about-us/who-we-are/member-state-committee/opinions-of-the-msc-adopted-under- specific-echa-s-executive-director-requests 4 The restriction on D4 and D5 entered into force in 31.1.2018 (European Commssion, 2018): xxxx://xxx- xxx.xxxxxx.xx/xxxxx-xxxxxxx/XX/XXX/?xxx=xxxxxxx:XX.X_.0000.000.00.0000.00.XXX […] • A steady-state BCF of 7,060 L/kg for Fathead Minnow Pimephales promelas (Xxxxxxx, 2005), based on total 14C measurements. • The steady state BCF for Common Carp Cyprinus xxxxxx in the range 12,049 – 12,617 L/kg (based on parent compound analysis) or 10,550 – 11,048 L/kg when normalised to a 5 per cent lipid content (CERI, 2010b). After the MSC and RAC opinion making processes new studies have been published. The relevant studies have been summarised in the Support document to this agreement. The new information does not deviate from the diverse data available earlier on bioaccumulation. The new data do not provide any reason to change the conclusion that the substance is vB reached by MSC and RAC.
Persistence. The clauses safeguarding the parties' proprietary rights, data, and intellectual property, notably 7, 8, 9, and 12, will remain in effect for 2 years after the termination of this AGREEMENT.
Persistence. The available experimental information shows that benzo[k]fluoranthene degrades very slowly in soil with half-life>180 days. Study performed under field conditions demonstrated a half-life of more than 8.7 years in soil. It is also assumed that benzo[k]fluoranthene meets the P and vP criterion in sediment, as in the available simulation study with phenanthrene the obtained half-life meets the P and vP criterion. Considering that the biodegradation rates decrease with increasing number of aromatic rings and the half-lives of PAHs in sediment are proportionally related to the octanol-water partition coefficient (Kow), the half-life of benzo[k]fluoranthene will meet the P and vP criterion in sediment as well. Therefore, the P and vP criteria according to Annex XIII of REACH Regulation are fulfilled for benzo[k]fluoranthene for soil and sediment. Limited data on the bioaccumulation potential of benzo[k]fluoranthene were reported in the EU Risk Assessment Report on CTPHT (European Commission, 2008)5 and in the Support Document for identification of CTPHT as SVHC (ECHA, 2009). The obtained BCF value for Daphnia magna was 13 225 L/kg for benzo[k]fluoranthene. Thus, benzo[k]fluoranthene has a high bioaccumulation potential at lower trophic levels, which could contribute to a constant high exposure of 5 European Commission (2008): European Union Risk Assessment Report, Coal Tar Pitch High Temperature, CAS No: 00000-00-0, EINECS No: 000-000-0. benzo[k]fluoranthene to predators for which the effects are unpredictable due to the absence of sufficient data. Benzo[k]fluoranthene meets the criteria for B and vB, in accordance to Annex XIII of REACH Regulation since the experimentally obtained BCF value for Daphnia magna was above 5 000 L/kg. A 42-day Early Life Stage study with Brachydanio rerio was given the highest weight. It provided an EC10 value (weight) of 0.31 µg/L and an EC10 value (length) of 0.17 µg/L. Length was the most sensitive endpoint. Therefore, benzo[k]fluoranthene fulfils the T criterion according to Xxxxx XXXX
Persistence. Persistence of a biodiversity element means that its loss (e.g. species extinction, ecosystem collapse) or decline (e.g. of numbers of mature individuals of a species, ecosystem extent and condition) is avoided, both now and into the foreseeable future. Significant means that an outstanding proportion of a biodiversity element (e.g. species population size or ecosystem extent) occurs at the site, as defined by a quantitative threshold. A geographical area on land and/or in water with defined ecological, physical, administrative or management boundaries that is actually or potentially manageable as a single unit (e.g. a protected area or other managed conservation unit). For this reason, large-scale biogeographic regions such as ecoregions, Endemic Bird Areas and Biodiversity Hotspots, and land-/seascapes containing multiple management units, are not considered to be sites. In the context of KBAs, “site” and “area” are used interchangeably.

Table 1 represents the persistence rates for RVC students overall and disaggregated by demographic subgroups, including enrollment status (full time or part time), gender, race/ethnicity, and age (traditional or nontraditional).

Disaggregated persistence rate data in Table 1 suggest: • Full-time students consistently persist at a higher rate than part-time students. • Over the five-year period reported, persistence rates decreased for part-time students, while persistence rates for full-time students remained relatively stable. • Black/African American students consistently persist at a lower rate than their peers in all other racial/ethnic groups. The persistence rate of Black/African American students decreased over the five-year period reported, widening the achievement gap between black and white students. • The persistence rate of Hispanic/Latino students has remained stable over the five-year period. The achievement gap between Hispanic/Latino and white students has generally narrowed. 1 Full-time students are enrolled in 12 credits or more, and part-time students are enrolled in less than 12 credit hours.
