Repeated implantation failure. Repeated implantation failure ( RIF) is the repeated failure of the embryo to implant onto the side of the uterus wall following IVF treatment. [1] Implantation happens at 6–7 days after conception and involves the embedding of the growing embryo into the mothers uterus and a connection being formed. [2]
Flight-time equivalent dose (FED) is an informal unit of measurement of ionizing radiation exposure. Expressed in units of flight-time (i.e., flight-seconds, flight-minutes, flight-hours), one unit of flight-time is approximately equivalent to the radiological dose received during the same unit of time spent in an airliner at cruising altitude.
The term "rabbit test" was first recorded in 1949, and was the origin of a common euphemism, "the rabbit died", for a positive pregnancy test. [4] The phrase was, in fact, based on a common misconception about the test. While many people assumed that the injected rabbit would die only if the woman was pregnant, in fact all rabbits used for the ...

Most people will stop testing positive on a rapid antigen COVID-19 test within about 10 days, Cardona says. "Within 10 days after your initial positive test, you should convert back to negative ...
The test is performed by administering a progestogen, such as progesterone either as an intramuscular injection or oral medroxyprogesterone acetate (Provera). If the patient has sufficient serum estradiol (greater than 50 pg/mL), withdrawal bleeding should occur 2–7 days after the progestin is withdrawn, indicating that the patient's ...

Silicon drift detectors ( SDD s) are X-ray radiation detectors used in x-ray spectrometry ( XRF and EDS) and electron microscopy. Their chief characteristics compared with other X-ray detectors are: high count rates. comparatively high energy resolution (e.g. 125 eV for Mn Kα wavelength) Peltier cooling.
