Chronobiology

Chronobiology is a field of biology that examines periodic (cyclic) phenomena in living organisms and their adaptation to solar- and lunar-related rhythms.

Effects of fatigue on safety

Fatigue is a major safety concern in many fields, but especially in transportation, because fatigue can result in disastrous accidents.

Nadir

The nadir (from نظير / ALA-LC: naẓīr, meaning "counterpart") is the direction pointing directly below a particular location; that is, it is one of two vertical directions at a specified location, orthogonal to a horizontal flat surface there.

Suprachiasmatic nucleus

The suprachiasmatic nucleus or nuclei (SCN) is a tiny region of the brain in the hypothalamus, situated directly above the optic chiasm.

Thermoregulation

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different.

Ultradian rhythm

In chronobiology, an ultradian rhythm is a recurrent period or cycle repeated throughout a 24-hour day.
