Capture

Capture

catching and holding a particle or an electrical impulse originating elsewhere.

Origin: L. Capio, pp. -tus, to take, seise

atrial capture, control of the atria for one or more beats after a period of independent beating, as in complete a-v block or in junctional or ventricular ectopic beats or tachycardias by a retrograde impulse.

electron capture, a mode of radioactive disintegration, in which an orbital electron, usually from the k shell, is captured by the nucleus, converting a proton into a neutron with ejection of a neutrino and emission of a gamma ray, and emission of characteristic x-rays as the missing k-shell electron is replaced.

Synonym: k capture.

Re: Device for ratiometric fluorescence measurement

... you'd need an excitation source and either two photodetectors or a means of manually switching the emission filter, plus the electronics to capture the photodetector output and do the ratiomatric comparison.

Bryophyte divesity

... area surveyed on X-axis). Usually, after a given distance, species diversity reaches an asymptote. If your data are asymptotic, you have probably captured most/all of the species diversity with your sampling method. If not, you probably need to sample further to capture the total diversity of ...

[NEUROSCIENCE]-USING X-RAYS TO IMAGE THE BRAIN?

... radiopacity, and it its complexity is seen in 3D (third dimension) => cannot get as much info from a 2D X-ray img. => can only really capture the complexity of the brain structure by taking 3D shots of it.

Re: Do the simplest bacteria have ribosomes and helicase?

... were likely producing biochemical precursors and replicating the molecules needed to catalyze the precursor-building reactions prior to their capture within a cell membrane. These reactions that build the parts of the system which catalyzes the reactions are termed a hypercycle. Here are Wikipedia ...

Video of rotifer eating.

I'm used to seeing Bdelloidea rotifers mostly, which are pretty motile, so hard to capture for very long, but I found this rotifer hanging out on some sediment. Not sure on the species, but the specimen did a good job of showing the current they create, as well as ...
