Normal human body temperature ( normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [8] [9] Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and menstruation ...
Comparison of temperature scales. * Normal human body temperature is 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F. The commonly given value 98.6 °F is simply the exact conversion of the nineteenth-century German standard of 37 °C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision.
It is not uncommon to find that the temperature of the aggregate is as much as 30 °C (54 °F) warmer than the surrounding air temperature on cold but sunny spring mornings. Later on in the spring, temperatures may become excessive at midday and the caterpillars may retreat to the shaded outside surface of the tent to cool down.
A typical family tipi is a conical, portable structure with two adjustable smoke flaps, multiple poles (historically from 12 to 25 ft or 3.7 to 7.6 m long) called lodge poles. Lewis H. Morgan noted that tipi frames were 13 to 15 poles that were 4.6 to 5.5 metres (15–18 ft) tall. These poles, "after being tied together at the small ends, are ...

It is a tent caterpillar, a social species that forms communal nests in the branches of trees. It is sometimes confused with the spongy moth (whose ...
Zone 5 uses eight 2-digit codes (51–58) and two sets of 3-digit codes (50x, 59x) to serve South and Central America. Zone 6 uses seven 2-digit codes (60–66) and three sets of 3-digit codes (67x–69x) to serve Southeast Asia and Oceania. Zone 7 uses an integrated numbering plan; two digits (7x) determine the area served: Russia or Kazakhstan.
