  2. Intrinsic viscosity - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_viscosity

    Intrinsic viscosity [] is a measure of a solute's contribution to the viscosity of a solution.If is the viscosity in the absence of the solute, is (dynamic or kinematic) viscosity of the solution and is the volume fraction of the solute in the solution, then intrinsic viscosity is defined as the dimensionless number [] = It should not be confused with inherent viscosity, which is the ratio of ...

  3. List of body armor performance standards - Wikipedia

    en.wikipedia.org/wiki/List_of_body_armor...

    The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.

  4. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [2] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [3]

  5. Equivalent concentration - Wikipedia

    en.wikipedia.org/wiki/Equivalent_concentration

    Here, ⁠ 1 / f eq ⁠ can have a fractional (non-integer) value. In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction. Here, ⁠ 1 / f eq ⁠ is an integer value. Normal concentration of an ionic solution is also related to conductivity (electrolytic) through the use of ...

  6. Serum-ascites albumin gradient - Wikipedia

    en.wikipedia.org/wiki/Serum-ascites_albumin_gradient

    A high gradient (> 1.1 g/dL, >11 g/L) indicates the ascites is due to portal hypertension, either liver related or non-liver related, with approximately 97% accuracy. [2] This is due to increased hydrostatic pressure within the blood vessels of the hepatic portal system , which in turn forces water into the peritoneal cavity but leaves proteins ...

  7. Reference ranges for blood tests - Wikipedia

    en.wikipedia.org/wiki/Reference_ranges_for_blood...

    Mass concentration (g/dL or g/L) is the most common measurement unit in the United States. Is usually given with dL (decilitres) as the denominator in the United States, and usually with L (litres) in, for example, Sweden. [citation needed]

  8. ISO metric screw thread - Wikipedia

    en.wikipedia.org/wiki/ISO_metric_screw_thread

    A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ...

  9. Tetrakis (triphenylphosphine)palladium (0) - Wikipedia

    en.wikipedia.org/wiki/Tetrakis(triphenylphosphine...

    PdCl 2 (PPh 3) 2 + 2 PPh 3 + 5 ⁄ 2 N 2 H 4 → Pd(PPh 3) 4 + 1 ⁄ 2 N 2 + 2 N 2 H 5 Cl. Both steps may be carried out in a one-pot reaction, without isolating and purifying the PdCl 2 (PPh 3) 2 intermediate. [5] Reductants other than hydrazine can be employed, including ascorbic acid. [6]
