  2. Gladstone–Dale relation - Wikipedia

    en.wikipedia.org/wiki/Gladstone–Dale_relation

    The plot of volume or density versus molecular fraction of ethanol in water is a quadratic curve. However, the plot of index of refraction versus molecular fraction of ethanol in water is linear, and the weight fraction equals the fractional density [4] In the 1900s, the Gladstone–Dale relation was applied to glass, synthetic crystals and ...

    88 zolotnik Russian silver has the equivalent millesimal fineness of 916[6]. The alloy contains 91.66% pure silver and 8.34% copper or other metals. (The description of the zolotnik is above.) [4] [8] Coin silver has a millesimal fineness of 900. The term "coin silver" was derived from the fact that much of it was made from melting down silver ...

    To allow comparison of results between people of different sizes, the C Cr is often corrected for the body surface area (BSA) and expressed compared to the average sized man as mL/min/1.73 m 2. While most adults have a BSA that approaches 1.7 m 2 (1.6 m 2 to 1.9 m 2), extremely obese or slim patients should have their C Cr corrected for their ...

  5. Lever rule - Wikipedia

    en.wikipedia.org/wiki/Lever_rule

    In chemistry, the lever rule is a formula used to determine the mole fraction (x i) or the mass fraction (w i) of each phase of a binary equilibrium phase diagram.It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.

  6. Close-packing of equal spheres - Wikipedia

    Coordinates of the centers of the first row will look like (2r, r, r), (4r, r, r), (6r ,r, r), (8r ,r, r), ... . Now, form the next row of spheres. Again, the centers will all lie on a straight line with x -coordinate differences of 2 r , but there will be a shift of distance r in the x -direction so that the center of every sphere in this row ...

  7. 4-8-8-4 - Wikipedia

    en.wikipedia.org/wiki/4-8-8-4

    Swiss classification: '4/6+4/6' The equivalent UIC classification is refined to (2′D)D2′ for simple articulated locomotives. A similar wheel arrangement exists for Garratt locomotives, but is referred to as 4-8-0+0-8-4 since both engine units swivel. 4-8-8-4 Big Boys were only produced for the Union Pacific Railroad. Twenty-five such ...

  8. Dilution ratio - Wikipedia

    en.wikipedia.org/wiki/Dilution_ratio

    In other areas of science such as pharmacy, and in non-scientific usage, a dilution is normally given as a plain ratio of solvent to solute. For large factors, this confusion makes only a minor difference, but in precise work it can be important to make clear whether dilution ratio or dilution factor is intended.

    Imperial Russian coinage between 1797 [10] and 1885. [11] 835: A standard predominantly used in Germany after 1884, and for some Dutch silver; and for the minting of coins in countries of the Latin Monetary Union; 833: (5 ⁄ 6) a common standard for continental silver especially among the Dutch, Swedish, and Germans
