This fern is dependent upon a constantly high air humidity which places severe restrictions on its distribution in the current climate of eastern North America.
32.
The mean annual precipitation is, the average wind speed is 2.7 m / s, and the average air humidity is 72 %.
33.
To prevent this, air humidity is kept low, below 50 %, and floor temperatures are maintained above the dew point, ( 66F ).
34.
Alternatively Humiditect cards or dataloggers ( measuring air humidity, air temperature, and surface temperature ) can be used as tools for diagnosing a condensation problem.
35.
For example, they inform about flight facilities before plane arrive, visibility, wind speed and direction, temperature and air humidity also height and cloud type.
36.
Research indicates that water content around 80 % of the carrying capacity of the soil and air humidity over 80 % ( during darkness ) are the most favorable conditions.
37.
I assume that the pot had been left standing to boil until it was basically dry, and so the air humidity in the kitchen would've been considerable.
38.
Other factors that contribute to the taste of the cheese are the air humidity, the low winter temperatures in Cherni Vit and the significant amplitude between day and night temperature.
39.
In drawing, plastic's specific advantages over translucent paper are higher mechanical strength and dimensional accuracy; plastic does not, unlike paper, shrink or stretch with changing air humidity.
40.
:I think it depends on the circuitry and on air humidity, but I certainly wouldn't touch it for half an hour, and I would be nervous up to two hours.
