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.
Liquid-in-Glass Thermometers. Calibrations in this laboratory are made by comparison with an ITS-90 calibrated standard platinum resistance thermometer in stirred liquid baths in the temperature range â196 ÂºC to 550 ÂºC. Additionally, the fixed-point measurement at the ice-melting point (0 Â°C) is available.
