In humans, hyperthermia is defined as a temperature greater than 37.5–38.3 °C (99.5–100.9 °F), depending on the reference used, that occurs without a change in the body's temperature set point. [20] [21] The normal human body temperature can be as high as 37.7 °C (99.9 °F). [24]
Hydrostatic weighing, also referred to as underwater weighing, hydrostatic body composition analysis and hydrodensitometry, is a technique for measuring the density of a living person's body. It is a direct application of Archimedes' principle , that an object displaces its own volume of water.
It has been proposed by scientists that the evolutionary reason for the female body shape is due in part to this sexual selection.Sex-typical body shapes (a man's muscular physique and a woman's hourglass figure) are an outcome of evolutionary adaptation for reproductive fitness because they convey information about gene quality, health and fertility, which are important elements for mate ...
In some cases measured arterial oxygen saturation values showed considerable arterial deoxygenation, with an extreme value of 25%. Heart rate changes similar to diving mammals in magnitude, and patterns of change were recorded, and changes in cardiac waveform at heart rates less than 40 beats per minute were linked to changes suggesting ...
A decomposing human body in the earth will eventually release approximately 32 g (1.1 oz) of nitrogen, 10 g (0.35 oz) of phosphorus, 4 g (0.14 oz) of potassium, and 1 g (0.035 oz) of magnesium for every kilogram of dry body mass, making changes in the chemistry of the soil around it that may persist for years.

This is because temperature not only affects the properties of the water, but also the organisms in the water, as most have an ideal range specific to their body and metabolic needs. Q10 (temperature coefficient) , the factor by which a rate increases at a 10 °C increase in temperature, is used to measure how organisms' performance relies on ...
Manuel swam at the 2012 United States Olympic Trials, placing 20th in the 50-meter freestyle and 17th in the 100-meter freestyle events. [1] [10] [11] The following month, as a 16-year-old at the 2012 Junior Pan Pacific Swimming Championships, held at the Veterans Memorial Aquatic Center in Honolulu, she won gold medals in the 100-meter freestyle with a time of 54.80 seconds, the 4×100-meter ...
