    en.wikipedia.org/wiki/Wikipedia:Database_download

    Start downloading a Wikipedia database dump file such as an English Wikipedia dump. It is best to use a download manager such as GetRight so you can resume downloading the file even if your computer crashes or is shut down during the download. Download XAMPPLITE from (you must get the 1.5.0 version for it to work). Make sure to pick the file ...

  4. Uchu Sentai Kyuranger - Wikipedia

    en.wikipedia.org/wiki/Uchu_Sentai_Kyuranger

    Kyuranger is considered the fifth space-themed series [a] whose primary motifs are constellations and Greco-Roman mythology, and it is also the first Super Sentai series to introduce nine regular members in the beginning instead of five or fewer like previous installments. The team later gains three additional members, increasing the number to ...

  5. Optical depth - Wikipedia

    en.wikipedia.org/wiki/Optical_depth

    Spectral optical depth or spectral optical thickness is the natural logarithm of the ratio of incident to transmitted spectral radiant power through a material. [1] Optical depth is dimensionless , and in particular is not a length, though it is a monotonically increasing function of optical path length , and approaches zero as the path length ...

  6. OD600 - Wikipedia

    en.wikipedia.org/wiki/OD600

    Spectrophotometer for OD600 and Cell Density Measurements OD600 (Also written as O.D. 600 , D 600 , o.d. 600 , OD 600 ) is an abbreviation indicating the optical density of a sample measured at a wavelength of 600 nm in 1 cm light path (unless otherwise stated).

  7. Densitometry - Wikipedia

    en.wikipedia.org/wiki/Densitometry

    DMax and DMin refer to the maximum and minimum density that can be produced by the material. The difference between the two is the density range. [1] The density range is related to the exposure range (dynamic range), which is the range of light intensity that is represented by the recording, via the Hurter–Driffield curve.

  8. Absorbance - Wikipedia

    en.wikipedia.org/wiki/Absorbance

    τ ν is the spectral optical depth in frequency, and; τ λ is the spectral optical depth in wavelength. Although absorbance is properly unitless, it is sometimes reported in "absorbance units", or AU. Many people, including scientific researchers, wrongly state the results from absorbance measurement experiments in terms of these made-up ...

  9. Microdensitometer - Wikipedia

    en.wikipedia.org/wiki/Microdensitometer

    The granularity measurement [2] involves the use of an optical aperture, 10-50 micrometers in diameter, and in the recording of thousands of optical density readings. The standard deviation of this series of measurements is known as the granularity [2] [3] of the measured transmission surface, optical film, or photographic film, in particular .
