a leading indicator
A health indicator is a measurement of how many people in a population have a given disease.
There are several ways that you can tell if a girl is leading you on. You should be observant on her commitment to the relationship which is a great indicator if she is serious or leading you on.
S&P 500 is considered to be a leading indicator. The high correlation that it has with DJ should give DJ some credibility too.
a leading indicator is a set of key variables that economists use to predict phase of a business cycle, and a stock market, typically, turns sharply downward before a recession begins.
GDP is considered a lagging indicator of economic performance because it reflects past economic activity rather than predicting future trends.
the economy slows down
The amount of indicator used in a titration can impact the accuracy of the endpoint determination. Using too much indicator can mask subtle color changes, leading to difficulty in pinpointing the endpoint. On the other hand, using too little indicator may cause the endpoint to be ambiguous or not easily detectable. It is important to carefully select the appropriate amount of indicator to ensure precise and reliable results.
Leading health indicators are structured to identify a number of objectives for improving the nation's health. They are health related concepts that reflect major public health concerns.
Flavin pigment molecule can interact with a pH indicator by changing its color based on the pH of the solution. The flavin pigment undergoes a chemical reaction with the pH indicator, leading to a change in its absorption spectrum or structure, resulting in a color change that can be used to determine the pH of the solution.
Using the vertical velocity indicator to control pitch attitude in an airplane is not recommended because the vertical velocity indicator shows the rate of climb or descent, not the pitch attitude. It can cause unintended pitch changes if relied upon for pitch control, potentially leading to unstable flight conditions or loss of control. It is best to use the attitude indicator or other instruments specifically designed for pitch control.
Indicators change color due to a chemical reaction between the indicator and the substance that alters the light absorption properties of the indicator molecule. This change in absorption properties results in a different color being observed. Different substances interact differently with the indicator molecule, leading to the color change.
