The dilution in welding terms is defined as the weight of the base metal melted divided by the total weight of the weld metal. For example, if we have a dilution of 0.40, the fraction of the weld metal that came from the consumable electrode is 0.60.
A serial dilution is the step-wise dilution of a substance in solution, either by using a constant dilution factor, or by using a variable factor between dilutions. If the dilution factor at each step is constant, this results in a geometric progression of the concentration in a logarithmic fashion. A ten-fold serial dilution could be 1 M, 0.1 ...
The following formulas can be used to calculate the volumes of solute (V solute) and solvent (V solvent) to be used: [1] = = where V total is the desired total volume, and F is the desired dilution factor number (the number in the position of F if expressed as "1/F dilution factor" or "xF dilution"). However, some solutions and mixtures take up ...
Illustration of regression dilution (or attenuation bias) by a range of regression estimates in errors-in-variables models. Two regression lines (red) bound the range of linear regression possibilities. The shallow slope is obtained when the independent variable (or predictor) is on the abscissa (x-axis).
Normality is defined as the molar concentration divided by an equivalence factor . Since the definition of the equivalence factor depends on context (which reaction is being studied), the International Union of Pure and Applied Chemistry and National Institute of Standards and Technology discourage the use of normality.
In perhaps the most involved tiebreaker situation of any league, four teams finished tied atop the Big 12 standings, each with a 7-2 record: Arizona State, Iowa State, Colorado and BYU.
Bill Clinton is one proud grandpa!. On Monday, Nov. 25, the former President of the United States, 78, appeared on an episode of Live with Kelly and Mark and spoke about how he and the former ...
The titer corresponds to the highest dilution factor that still yields a positive reading. [2] For example, positive readings in the first 8 serial, twofold dilutions translate into a titer of 1:256 (i.e., 2 −8). Titres are sometimes expressed by the denominator only, for example 1:256 is written 256. [3]
