The Well-Being Index is an online self-assessment tool invented by researchers at Mayo Clinic that measures mental distress and well-being in seven-nine items. [1] [2] The Well-Being Index is an anonymous tool that allows participants to reassess on a monthly basis, track their well-being scores over time, compare their results to peers' and national averages, and access customized resources ...
Microbarometers are sensitive barometers that can measure air pressure with high precision. Microbarometers typically have a resolution of microbars (μbar) or pascals (Pa), while ordinary barometers [1] can only resolve in hectopascals (hPa) or millibars (mbar).
The greater the altitude, the lower the pressure. When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is a type of altimeter called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft, and skydivers use wrist-mounted versions for similar ...
The changing height of the mercury in the barometer was recorded on a continuously moving photosensitive surface. [5] By 1847, a sophisticated temperature-compensation mechanism was also employed. Ronalds’ barograph was utilised by the UK Meteorological Office for many years to assist in weather forecasting and the machines were supplied to ...
The tempest prognosticator, also known as the leech barometer, is a 19th-century invention by George Merryweather in which leeches are used in a barometer.
