In the bottom centre is the aneroid (large circular silver object). As the pressure increases, the aneroid is pushed down causing the arm to move up and leave a trace on the paper. As the pressure decreases, the spring lifts the aneroid and the arm moves down. After three days the drum to which the graph is attached is removed.
A barograph is a recording aneroid barometer where the changes in atmospheric pressure are recorded on a paper chart. The principle of the barograph is same as that of the aneroid barometer. Whereas the barometer displays the pressure on a dial, the barograph uses the small movements of the box to transmit by a system of levers to a recording ...
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
The measurements taken include temperature, barometric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken as free of other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once ...

A number of studies have linked red wine consumption with heart health benefits, including reduced LDL (known as “bad”) cholesterol levels, better blood pressure and blood vessel function and ...
Anthony Richardson scored on a 2-point conversion run up the middle with 12 seconds remaining in the fourth quarter to give the Indianapolis Colts a 25–24 win over the New England Patriots on ...
Respiratory pressure meter Measuring respiratory muscle strength is a long-established method of assessing the mechanics of breathing. Respiratory muscle dysfunction (i.e., reduced strength or endurance) should be distinguished from lung function abnormalities and measured separately.
