Performance, If it's mil-dtl, it's detail
Answer: PRF (Personnel Readiness File/Folder) files are used in technical application and are not likely to be accessed by your average PC user. In general, PRF files are Windows system files, although they have other technical applications as well.
1. PRF is based on population data as a whole, SRF is based on Sample data 2. We can draw only one PRF line from a given population. But we can Draw one SRF for one sample from that population. 3. PRF may exist only in our conception and imagination. 4. PRF curve or line is the locus of the conditional mean/ expectation of the independent variable Y for the fixed variable X in a sample data. SRF shows the estimated relation between dependent variable Y and explanatory variable X in a sample.
The prf means the coin is a proof, proof coins are not intended for circulation and have mirror like fields (spaces where there is no design) and generally frosty designs. US coins are graded on a scale from 1-70 with 1 being barely readable and 70 being absolute perfection. Prf 65 is a fairly low grade for a US proof made recently. For older coins Prf 65-66 are typical due to damage from improper storage. But for newer proofs, prf 68 is low and 69 and 70s are common.

you complete the pokedex for prf. rown and then he gives it to you. :)
Platelet rich in fibrin (PRF) is known to have several advatages over platelet rich plasma PRP) including: 1-Unlike PRP, with PRF no anticoagulant or/and antiplatelet therapy is needed, hence diminishing risks for bleeding. 2-PRP is effective when used on soft tissue only, while PRF could be utelized in treatments plans for both soft and hard tissue. 3-PRF is prepared faster and easier, rendering PRP less time effective.
DME interrogator uses random PRF(pri) technique.it receives the pulse pairs with same PRF(PRI).calculates the time from sending the signal to receiving -50 micro secs/12.36 and multiplies with speed of light can i know any machine or something can we measure micr level
