Why do we have more fever at night?
It is this inflammation that will trigger fever, stuffy nose, or sore throat. Since the immune system kicks into high gear during sleep, the symptoms become more severe. This heightened activity of the immune system can last for the night.
Know how to take oral temperature He just place a thermometer mouth under the tongue for about 3 minutes. He is recommended toadd 0.5°C to the displayed temperature. He not should never use this method after ingesting a hot or iced drink, the results would be completely distorted.
The hardness H is given by the ratio of the maximum applied load Pmax to the area A of indenter/sample contact. Scratching hardness measurement is the oldest method of hardness measurement which gave rise to the first hardness scale proposed by Mohs in 1820.
The devices are normally calibrated to obtain a hardness of 100 for a hardened steel with 0.9% carbon and around 35 for mild steels. Indentation hardness measurement is the most commonly practiced. The principle is always the same: a dimensionally stable indenter leaves an imprint in the material to be tested.
Hardness is measured on different scales depending on the type of material considered. Unlike minerals whose hardness is characterized by scratching (Mohs scale), rebound or penetration tests are generally used to characterize the hardness of metals, plastics and elastomers.
In fact there is a more general theorem: Thus, a polynomial of degree 8 has AT MOST 8 roots, it can have 8, 7, 6, 5, 4, 3, 2, 1, or 0!! A polynomial of degree 12 has AT MOST 12 roots, etc… A polynomial of degree 2 therefore has at most 2 roots!
