Hyperthermia is defined as supra-normal body temperatures. There is no consensus as to what is the safest or most effective target temperature for the whole body. During treatment the body temperature reaches a level between 39.5 and 40.5 °C (103.1 and 104.9 °F). [4]
Internationally agreed temperature scales are designed to approximate this closely, based on fixed points and interpolating thermometers. The most recent official temperature scale is the International Temperature Scale of 1990. It extends from 0.65 K (−272.5 °C; −458.5 °F) to approximately 1,358 K (1,085 °C; 1,985 °F).
[citation needed] Sheets of amorphous selenium convert X-ray images to patterns of charge in xeroradiography and in solid-state, flat-panel X-ray cameras. [91] Ionized selenium (Se+24, where 24 of the outer D, S and P orbitals are stripped away due to high input energies [ clarification needed ] ) is one of the active mediums used in X-ray lasers.
By 1901, it could detect radiation from a cow from 400 metres away and was sensitive to differences in temperature of one hundred thousandths (0.00001 C) of a degree Celsius. [ 47 ] [ 48 ] The first commercial thermal imaging camera was sold in 1965 for high voltage power line inspections.
The scale is an absolute temperature scale with the same increment as the Celsius temperature scale, which was originally defined according to the boiling point (set to 100 °C (212 °F)) and melting point (set to 0 °C (32 °F)) of water.
While a rising birth rate is contributing to population growth, it remains considerably below the baby boom peak of 2.95 children per woman in 1964, [351] or the high of 6.02 children born per woman in 1815, [352] below the replacement rate of 2.1, but higher than the 2001 record low of 1.63. [353]
Montreal [a] is the largest city in the province of Quebec, the second-largest in Canada, and the ninth-largest in North America.It was founded in 1642 as Ville-Marie, or "City of Mary", [19] and is now named after Mount Royal, [20] the triple-peaked mountain around which the early settlement was built.

The highest recorded temperature was on 14 August 2021, with 40.7 °C (105.3 °F) and the lowest recorded temperature was on 16 January 1945 with −10.1 °C (13.8 °F) in Madrid. [101] While at the airport, in the eastern side of the city, the highest recorded temperature was on 14 August 2021, at 42.7 °C (108.9 °F), and the lowest recorded ...
