Solanum dulcamara is a species of vine in the genus Solanum (which also includes the potato and the tomato) of the family Solanaceae.Common names include bittersweet, bittersweet nightshade, bitter nightshade, blue bindweed, Amara Dulcis, [3] climbing nightshade, [4] felonwort, fellenwort, felonwood, poisonberry, poisonflower, scarlet berry, snakeberry, [5] [6] [7] trailing bittersweet ...
Serial dilution of a solution results, after each dilution step, in fewer molecules of the original substance per litre of solution. Eventually, a solution will be diluted beyond any likelihood of finding a single molecule of the original substance in a litre of the total dilution product. The "Korsakovian" method may also be used.
The potion has worked quite well for everyone, as Dulcamara reveals his potion to everyone. It is eventually discovered that Adina is Dulcamara's daughter and Nemorino's cousin, Belcore is Tomaso's son, Gianetta is Tomaso's granddaughter, and she is Belcore's lost daughter. Beppo finally reveals his secret – he is Dulcamara's long lost mother!
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 ...
At greater dilutions the indirect Coombs test is negative. If a few weeks later the same patient had an indirect Coombs titer of 32 (1/32 dilution which is 1 part serum to 31 parts diluent), this would mean that she was making more anti-Rh antibody, since it took a greater dilution to abolish the positive test.
Tutorial illustration of isotope dilution analysis with fish counting in lakes. Isotope dilution is analogous to the mark and recapture method, commonly used in ecology to estimate population size. For instance, consider the determination of the number of fish (n A) in a lake. For the purpose of this example, assume all fish native to the lake ...
Elution principle of column chromatography. In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent: washing of loaded ion-exchange resins to remove captured ions, or eluting proteins or other biopolymers from a gel electrophoresis or chromatography column.
