| EHF | epidemic hemorrhagic fever; exophthalmos-hyperthyroid factor; extreme high frequency |
|---|---|
| ELF | elective low forceps; extremely low frequency |
| Fc | centroid frequency; fraction/centrifuge; fragment, crystallizable [of immunoglobulin] |
| FCF | fetal cardiac frequency; fibroblast chemotactic factor |
| FDFQ | Food/Drink Frequency Questionnaire |
| fusion temperature | The recorded temperature at which a 20-gauge metal wire will collapse under a 3-ounce load; the recorded temperature at which porcelain becomes glazed. (05 Mar 2000) |

| light-ion fusion | <radiobiology> Light-Ion-Beam-Driven Inertial Confinement fusion, using beams of light ions driven at implosion targets. Pulsed-power driven accelerators are relatively efficient and cost-effective, but beam-focusing is a technical hurdle for this approach. (09 Oct 1997) |
| lysosome phagosome fusion | <cell biology> A process that occurs after the internalisation of a primary phagosome. Fusion of the membranes leads to the release of lysosomal enzymes into the phagosome. Some species of intracellular parasite evade immune responses by interfering with this process. (18 Nov 1997) |
