Retardation or factor of retention on a chromatogram, the (RF) value is the ratio of the distance travelled by the analyte to the distance travelled by thesolventfront. The movement of analytes with mobile solvents differs between chromatographic techniques in which analytes are added to stationary ...
Why?Rf Value:The Rf value of a substance is a term that originated in chromatography and chemical analysis. It stands for retardant factor and represents the ratio between the solute's distance traveled to the solvent's distance traveled.Answer and Expla...
dB, dBm, dBc, dBW dB is one of the most common measurement unit in RF area. The methematical definition of dB is as follows. It is just a number presented in log scale. So there is not many things I can say in terms of definition. It is the value of Power in log scale. or ...

Even in the microwave area, structures included in the definition of integrated electronics will become increasingly important. The ability to make and assemble components small compared with the wavelengths involved will allow the use of lumped parameter design, at least at the lower frequencies....
The shielding thickness of the hot cells and the transfer systems (from the bunker of the ion source to the radiochemistry facility) will be calculated or chosen based on the type, energy, and activity of the radioactive material being handled and on the activities carried out. Whenever ...
Rare objects are often of great interest and great value. Until recently, however, rarity has not received much attention in the context of data mining. Now, as increasingly complex real-world problems are addressed, rarity, and the rela... NV Chawla,N Japkowicz,A Kotcz - 《Acm Sigkdd...
By definition, it represents a judgment that something said, written, or done is utterly without value, devoid of interest, and either stupid or silly or both. The choice of a Venn diagram* for communicating absolutist determinations is interesting in this regard. The Venn is not a ...
