How to measure body temperature correctly - Microlife AG

Human body temperature varies depending on where on the body the temperature is taken and the time of measurement. This is due to physiological factors and must be distinguished from thermometer malfunction. Measurement accuracy primarily depends on whether the thermometer is used correctly (read the operating instructions!). The following applies: The body temperature measured is always ...

Lecture 6: Thermal Radiation

humans are sensitive to: blue ( µm); green ( µm); ... Approximation is better than 1% when hc/!kT << 1 or !T > m K. For example, for a body at 300 ûK, the approximation is valid when ! > mm; in other words this approximation is good when viewing thermal emissions from the Earth over the microwave band. The total emitted radiation (M!) from a black body is ...

Human body temperature - Wikipedia

· Normal human body-temperature is the typical temperature range found in humans. The normal human body temperature range is typically stated as –37 °C. Human body temperature varies. It depends on gender, age, time of day, exertion level, health status, what part of the body the measurement is taken at, state of consciousness, and emotions. Body temperature is kept in the normal range by thermoregulation, in which adjustment of temperature …

Black body - Wikipedia

Using this model the effective temperature of stars is estimated, defined as the temperature of a black body that yields the same surface flux of energy as the star. If a star were a black body, the same effective temperature would result from any region of the spectrum. For example, comparisons in the B (blue) or V (visible) range lead to the so-called B-V color index, which increases the ...

Regulation of body temperature by the nervous system

· Feed-forward and feedback regulation of body temperature. Body temperature is not a single value but varies depending on where it is measured. In studies of thermoregulation, it is common to divide the body into two compartments: (1) the external shell, which includes the skin and largely fluctuates in temperature along with the environment, and (2) the internal core, which includes the ...
