Examples of serial dilution in the following topics:
-
- Serial dilutions involve diluting a stock or standard solution multiple times in a row.
- For example, a ten-fold serial dilution could result in the following concentrations: 1 M, 0.1 M, 0.01 M, 0.001 M, and so on.
- Serial dilutions are used to accurately create extremely diluted solutions, as well as solutions for experiments that require a concentration curve with an exponential or logarithmic scale.
- Serial dilutions are widely used in experimental sciences, including biochemistry, pharmacology, microbiology, and physics.
- This video shows how to solve two dilution problems, using the standard dilution formula, M1V1 = M2V2.
-
- The laboratory procedure involves making serial dilutions of the sample (1:10, 1:100, 1:1000 etc. ) in sterile water and cultivating these on nutrient agar in a dish that is sealed and incubated.
- The initial analysis is done by mixing serial dilutions of the sample in liquid nutrient agar which is then poured into bottles.
- Calculation of this is a multiple of the counted number of colonies multiplied by the dilution used.
- Examples of a viable cell count are spread plates from a serial dilution of a liquid culture and pour plates.
- With a spread plate one makes serial dilutions in liquid media and then spreads a known volume from the last tube in the dilution series.
-
- A serial dilution is the step-wise dilution of a substance in solution.
- A ten-fold serial dilution could be 1 M, 0.1 M, 0.01 M, 0.001 M...
- Serial dilutions are used to accurately create highly-diluted solutions as well.
- For a ten-fold dilution on a 1 mL scale, vials are filled with 900 microliters of water or media, and 100 microliters of the stock microbial solution are serially transferred, with thorough mixing after every dilution step.

- Diluted earnings per share (EPS) takes the basic EPS formula and accounts for the effect of dilutive shares on earnings.
- Diluted Earnings Per Share (diluted EPS) is a company's earnings per share (EPS) calculated using fully diluted common shares outstanding (i.e. which includes the impact of instruments such as stock option grants and convertible bonds).
- Fully diluted common shares consider securities with features that will increase the number of common shares outstanding and reduce (dilute) earnings per share.
- Diluted earnings per share includes shares of common stock from dilutive securities, such as convertible debt or stock options, in its calculation.
- Explain why a company would calculate diluted earning per share for its stock

- Serial memory processing compares a memory to a target stimulus, while parallel processing carries out multiple operations simultaneously.
- Serial memory processing is the act of attending to and processing one item at a time.
- The serial order of items and the relationships between them can have varying affects on the item's speed and accuracy of recall.
- Serial memory processing can be either self-terminating or exhaustive.
- Participants may process some serial memory sets using the self-terminating method and in other cases use the exhaustive method.

- Diluted Earnings Per Share (diluted EPS) is a company's earnings per share (EPS) calculated using fully diluted outstanding shares (i.e. including the impact of stock option grants and convertible bonds).
- To find diluted EPS, basic EPS is first calculated for each of the categories on the income statement.
- Then each of the dilutive securities are ranked based on their effects, from most dilutive to least dilutive and antidilutive.
- Calculations of diluted EPS vary.
- This is adjusted for dilutive shares.
-
- There are three main types of recall studied in psychology: serial recall, free recall, and cued recall.
- This is called serial recall and can be used to help cue memories.
- Serial recall helps a person to remember the order of events in his or her life.
- When recalling serial items presented as a list (a common occurrence in memory studies), two effects tend to surface: the primacy effect and the recency effect.
- Like serial recall, free recall is subject to the primacy and recency effects.
-
- The new shares dilute the value of the existing shares, and this is understandably, typically not looked upon kindly by those who own shares before the dilution.
- In theory, this dilution should correspond directly to a drop in the share price such that the market capitalization of the company remains the same.
- The sale of the shares does not benefit the company, and, more importantly, is not dilutive.
- The dilution of the shares outstanding should theoretically be met with a corresponding drop in share price.

- For example, MacMillan Bloedel, one of Canada's largest forest product companies, was labelled a serial forest-clearer and a chronic chlorine user by environmental activists and subsequently lost 5% of its sales almost overnight when it was dropped as a UK supplier by Scott Paper and Kimberley Clark.
