Count dates greater than or equal to another date. =COUNTIF(B2:B10,>=6/1/2014) Count the number of cells in the range B2:B10 with a date greater than or equal to 6/1/2014. Count dates greater than or equal to a date in another cell, minus x days. =COUNTIF(B2:B10,>=&B2-7) Count the number of cells in the range B2:B10 with a date greater than or equal to the date in B2 minus 7 days.
A polygraph is a machine, or a test using said machine, which measures the changes in a person's body, such as pulse, breathing rate, and skin temperature.It is used as a lie detection test.It is based on the principle that when lying, one will become nervous and have an increased pulse and need for air. polygraph is a machine, or a test using said machine, which measures the changes in a person's body, such as pulse, breathing rate, and skin temperature.
A non-adjustable thermometer may be used to measure the temperature of a reflective surface by applying a non-reflective paint or tape, with some loss of accuracy. A sensor with an adjustable emissivity setting can also be used to calibrate the sensor for a given surface, or to measure the emissivity of a surface. non-adjustable thermometer may be used to measure the temperature of a reflective surface by applying a non-reflective paint or tape, with some loss of accuracy.
