dilution

 [di-loo´shun]
1. reduction of concentration of an active substance by admixture of a neutral agent.
2. a substance that has undergone such a process.
serial dilution a set of dilutions in a mathematical sequence. In microbiological technique, serial dilutions are used to obtain a culture plate that yields a countable number of separate colonies. From this, a calculation of viable cells in the original suspension can be made, as a colony picked for pure culture.

di·lu·tion

(dī-lū'shŭn),
1. The act of being diluted.
2. A diluted solution or mixture.
3. In microbiologic techniques, a method for counting the number of viable cells in a suspension; a sample is diluted to the point where an aliquot, when plated, yields a countable number of separate colonies.

limit dilution
a method of obtaining a pure culture of bacteria or virus by subculturing from the highest dilution in which the organism is demonstrably present.
serial dilution
1. the progressive dilution of a substance or infectious agent in a series of tubes or wells in a tray in predetermined ratios, e.g. 2-fold or 10-fold dilution steps.
2. a method of obtaining a pure bacterial culture by rapid transfer of a small amount of material from one nutrient medium to a succeeding one of the same volume.

Section V concludes the paper and discusses the implications of our results for financial reporting on dilutive securities.
Dilutive securities reduce the magnitude of abnormal stock returns associated with a given amount of unexpected earnings, because they reduce investors' expectations of their share of future firm cash flows.
Dilutive securities, however, make an increase in the number of shares likely.
When dilutive securities are outstanding, we define the revision in expected future earnings, arising from a time t earnings shock, that accrues to a current-period shareholder, as [[epsilon].
t][[DELTA]N(t,t + [tau])] is the expected number of dilutive shares issued between t and t + [tau].
If those contracts are "in the money" during the reporting period, the potential dilutive effect should be computed using the reverse treasury stock method.
The dilutive effect of stock[degree sign] based computation arrangements should be computed using the treasury stock method.
The dilutive effect of convertible securities should be reflected in diluted E?
Dilutive convertible securities that are issued during a period in circumstances where conversion options lapse, preferred stock is redeemed, or related debt is extinguished should be included in the denominator of diluted EPS for the period that they were outstanding.
In this case, basic and diluted EPS would be the same number, even if dilutive securities are present in the capital structure.
15, the tests for determining common stock equivalency status and the means of including dilutive securities in EPS calculations were strongly criticized.
Although this method assumes management intends to use the proceeds to repurchase stock and dampens the dilutive effect of options and warrants, the FASB would retain its use.
