IMB
From Free net encyclopedia
IMB is the abbreviation for Independent Monitoring Board. IMBs are appointed by the UK Home Secretary to monitor and report on the conditions in which prisoners are held in English and Welsh jails. IMBs are also appointed to Immigration Removal Centres in the UK.
Members of IMBs are empowered by the Prison Act 1952, however the Boards themselves have existed in some form or other for over a century.

IMB can also refer to the International Mission Board of the Southern Baptist Convention.
IMB is the abbreviation for the Institute of Marine Biosciences, part of the National Research Council of Canada.
IMB was a neutrino observatory located in a salt mine on the shore of Lake Erie in the United States. It was a joint venture of the University of California, Irvine, the University of Michigan, and the Brookhaven National Laboratory (hence the acronym).
IMB consisted of a roughly cubical tank about 20 meters on a side, full of ultrapure water which was surrounded by 2,048 photomultiplier tubes. IMB detected neutrinos by picking up the Cerenkov radiation generated when a neutrino collides with either a proton or an electron (both of which are plentiful in water), and was thus able to estimate the direction of the neutrino by analysing the spatial arrangement of the tubes that detected visible radiation.
The efficiency of IMB was quite low: if 100 trillion neutrinos pass through the detector, on average only one will be detected. This was not so much a reflection of the nature of the device's sensitivity (which was quite high), but rather the "aloof" nature of the largely non-interacting neutrino itself, which is only capable of interacting with normal matter via the electroweak force and gravity.
IMB is famous for having detected 8 of the roughly <math>10^{58}</math> neutrinos emitted by Supernova 1987a.
IMB is the acronym for the scientific journal Insect Molecular Biology
