  2. Basis point - Wikipedia

    en.wikipedia.org/wiki/Basis_point

    A related concept is one part per ten thousand, ⁠ 1 / 10,000 ⁠.The same unit is also (rarely) called a permyriad, literally meaning "for (every) myriad (ten thousand)". [4] [5] If used interchangeably with basis point, the permyriad is potentially confusing because an increase of one basis point to a 10 basis point value is generally understood to mean an increase to 11 basis points; not ...

    Sign Units Used in 1 percent (%), 1 g% [6] 1 g/dL = 1 cg/mL = 10 g/L = 1 g/100 mL: US, Australia, [6] [7] Canada [8] 1 per mille (‰) [a]: 1 g/L = 1 mg/mL = 100 mg/1 ...

  4. Adaptive coding - Wikipedia

    en.wikipedia.org/wiki/Adaptive_coding

    Adaptive coding refers to variants of entropy encoding methods of lossless data compression.They are particularly suited to streaming data, as they adapt to localized changes in the characteristics of the data, and don't require a first pass over the data to calculate a probability model.

  5. Proton nuclear magnetic resonance - Wikipedia

    The total area of the 1 ppm CH 2 peak will be twice that of the 2.5 ppm CH peak. The CH 2 peak will be split into a doublet by the CH peak—with one peak at 1 ppm + 3.5 Hz and one at 1 ppm − 3.5 Hz (total splitting or coupling constant is 7 Hz). In consequence the CH peak at 2.5 ppm will be split twice by each proton from the CH 2. The first ...

    At an odor detection threshold of 0.2 mg/L in white wines and 2.8 mg/L in red wines, it can be perceived as slightly buttery or "nutty" while at concentrations greater than 5 to 7 mg/L (5-7 ppm) can overwhelm other aroma notes in the wine. [7] [10] Diacetyl can be produced by the LAB through metabolism of sugar or of citric acid. [11]

    Typically, purities of 99.995% or higher are used. The most common purity grades required by modern instruments for the majority of sensitivities are 5.0 grades, or 99.999% pure meaning that there is a total of 10 ppm of impurities in the carrier gas that could affect the results.

  8. Homeopathic dilutions - Wikipedia

    en.wikipedia.org/wiki/Homeopathic_dilutions

    In homeopathy, homeopathic dilution (known by practitioners as "dynamisation" or "potentisation") is a process in which a substance is diluted with alcohol or distilled water and then vigorously shaken in a process called "succussion".

  9. Uranium mining - Wikipedia

    One highly criticized [176] life cycle study by Jan Willem Storm van Leeuwen suggested that below 0.01–0.02% (100–200 ppm) in ore, the energy required to extract and process the ore to supply the fuel, operate reactors and dispose properly comes close to the energy gained by using the uranium as a fissible material in the reactor.
