A water temperature of 10 °C (50 °F) can lead to death in as little as one hour, and water temperatures near freezing can cause death in as little as 15 minutes. [37] During the sinking of the Titanic , most people who entered the −2 °C (28 °F) water died in 15–30 minutes.
Treatment to reduce fever is generally not required. [2] [9] Treatment of associated pain and inflammation, however, may be useful and help a person rest. [9] Medications such as ibuprofen or paracetamol (acetaminophen) may help with this as well as lower temperature.
[133] [134] Fever is caused by elevated levels of prostaglandin E2 (PGE2), which alters the firing rate of neurons within the hypothalamus that control thermoregulation. [ 133 ] [ 135 ] Antipyretics work by inhibiting the enzyme COX, which causes the general inhibition of prostanoid biosynthesis (PGE2) within the hypothalamus.
The highest recorded temperature is 108 °F (42 °C) in July 1936 while the lowest is −41 °F (−41 °C) in January 1888. [210] The snowiest winter on record was 1983–1984, when 98.6 in (250 cm) of snow fell. [211] The least-snowy winter was 1930–1931, when 14.2 inches (36 cm) fell. [211]
Further divisions of the segmental bronchi (1 to 6 mm in diameter) [7] are known as 4th order, 5th order, and 6th order segmental bronchi, or grouped together as subsegmental bronchi. [ 8 ] [ 9 ] Compared to the 23 number (on average) of branchings of the respiratory tree in the adult human, the mouse has only about 13 such branchings.
At a pressure of 1 atm (0.101325 MPa), the gas deposits directly to a solid at temperatures below 194.6855(30) K [2] (−78.4645(30) °C) and the solid sublimes directly to a gas above this temperature. In its solid state, carbon dioxide is commonly called dry ice. Pressure–temperature phase diagram of carbon dioxide. Note that it is a log ...
Vitamin C concentrations in various food substances decrease with time in proportion to the temperature at which they are stored. [36] Cooking can reduce the vitamin C content of vegetables by around 60%, possibly due to increased enzymatic destruction. [37] Longer cooking times may add to this effect. [38]
Cholera (/ ˈ k ɒ l ər ə /) is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. [4] [3] Symptoms may range from none, to mild, to severe. [3]The classic symptom is large amounts of watery diarrhea lasting a few days. [2]
