A radar altimeter (RA), radio altimeter (RALT), electronic altimeter, or reflection altimeter measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft.

Immobilized bacteria are bacteria that have been confined to a limited region by attachment to a solid structure. (Abdullahi, H. 2021.

Extrauterine (ectopic) pregnancy is the implantation of a fertilized oocyte outside the uterine cavity. (Taran FA, Kagan KO, Hübner M, Hoopmann M, Wallwiener D, Brucker S. The Diagnosis and Treatment of Ectopic Pregnancy. Dtsch Arztebl Int. 2015 Oct 9;112(41):693-703; quiz 704-5. doi: 10.3238/arztebl.2015.0693. PMID: 26554319; PMCID: PMC4643163.)

Process that involves forcing a material to flow under a variety of controlled conditions and then to pass through a shaped hole or slot at a predeterminate rate. (Bouroche, A., Le Bars, M. 1996. Extrusion Cooking: A French-English-German Vocabulary, INRA.)

The process of producing identical copies (clones) of a gene (http://www.science.org.au/nova/013/013glo.htm)

In cell biology, the term DNA cloning is used in two senses. In one sense it literally refers to the act of making many identical copies of a DNA molecule—the amplification of a particular DNA sequence. However, the term is also used to describe the isolation of a particular stretch of DNA (often a particular gene) from the rest of a cell's DNA, because this isolation is greatly facilitated by making many identical copies of the DNA of interest. (Alberts B, Johnson A, Lewis J, et al. Molecular Biology of the Cell. 4th edition. New York: Garland Science; 2002. Isolating, Cloning, and Sequencing DNA. Available from: https://www.ncbi.nlm.nih.gov/books/NBK26837/)

In geophysics, the free-air gravity anomaly, often simply called the free-air anomaly, is the measured gravity anomaly after a free-air correction is applied to correct for the elevation at which a measurement is made. (https://en.wikipedia.org/wiki/Free-air_gravity_anomaly)

A synthetic plasmid which incorporates the cos ends, and one or more selectable markers such as an antibiotic resistance gene. Cosmids were designed as vectors able to incorporate DNA fragments up to 40-50 kb in size.

Excrement from the intestines, containing unabsorbed solids, waste products, secretions, and bacteria of the digestive system. (DeCS/MESH. 2025. Feces https://decs.bvsalud.org/en/ths/resource/?id=5346)

Conversion of atmospheric nitrogen (e.g. by bacteria in legume root nodules) into plant-usable form. (FAO, 2016. Save and Grow in Practice: Maize, Rice, Wheat. A Guide to Sustainable Cereal Production http://www.fao.org/3/a-i4009e.pdf Cited 14 April 2023.)
