Rarefaction (ecology) Rarefaction (ecology) In ecology, rarefaction is a technique to assess species richness from the results of sampling. Rarefaction allows the calculation of species richness for a given number of individual samples, based on the construction of so-called rarefaction curves. This curve is a plot of the number of species as a function of the number of samples.

What is liquefaction in earthquakes? Confidence votes 23.8K. Liquefaction is the name given to the process that converts a solid soil mass into a liquid. Liquefaction occurs in cohesionless soils (typically those with a higher content of larger grains such as sand sized clasts) which have water in the pore spaces, and are poorly drained.

Mimicry Olfaction, also known as olfactics, is the sense of smell. This sense is mediated by specialized sensory cells, called olfactory receptors, in the nasal cavity of vertebrates that are analogous to sensory cells in the antennae of invertebrates. In humans, olfaction – the detection of smells – occurs when odorant molecules bind to specific sites on these receptors.

Compression Wave: Definition & Overview A compression is the part of the wave (or Slinky) that is pressed together -- this is like the crest or peak of the wave. A rarefaction is the part of the wave (or Slinky) that is the most spread apart -- this is like the trough of the wave.

17.4 Hearing and Vestibular Sensation Compression and rarefaction refer to the movement of particles in a wave through a medium, such as air or water. Compression is the movement of particles together, into …high density areas, and rarefaction is the movement of particles away from each other into lower density areas.

Rare-earth magnet Ferrofluid on glass, with a rare-earth magnet underneath Rare-earth magnets are strong permanent magnets made from alloys of rare-earth elements (elements in the lanthanide series, plus scandium and yttrium). Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.

"Rare mutations do not explain ""missing heritability"" in asthma" Largest study to date of rare genetic variants and asthma risk finds few associations. Despite a strong suspected link between genetics and asthma, commonly found genetic mutations account for only a small part of the risk for developing the disease -- a problem known as missing heritability.

Contiguity The contiguity of a pair of sequences of probability measures is a property that relates to the commonality of the sets that have zero measure as the index in the sequence increases. See Contiguity (probability theory) .

Definitions &Translations Torrefaction leads to a dry product with no biological activity like rotting. Torrefaction combined with densification leads to a very energy-dense fuel carrier of 20 to 21 GJ/ton lower heating value (LHV). Torrefaction makes the material undergo Maillard reactions.

rare If an event is rare, it doesn't happen often. If an object is rare, there aren't many of its kind. Obviously, finding a rare gem is a rare occasion. Rare comes from the Latin word rarus, meaning “widely spaced,” as rare things are — whether in actual space or in time. You thought it was rare to meet someone you have so much in common with, until he fainted looking at the rare steak you ordered.

Rarefaction If the prong of a tuning fork vibrates in the air, for example, the layer of air adjacent to the prong undergoes compression when the prong moves so as to squeeze the air molecules together. When the prong springs back in the opposite direction, however, it leaves an area of reduced air pressure. This is rarefaction. A succession of rarefactions and compressions makes up the longitudinal wave motion that emanates from an acoustic source.
