It most often affects the legs at night, but many suffer from variations of this.

The project did not operate for a long enough time to show statistically any change from natural variations.

Various theories explain how the changes could have resulted from variations in one or more of the following:

Other differences come from variations in the processing steps.

Timing is different for each, but all bloom only briefly, then stop, taking their cues from variations in day length.

A hierarchical structure of matter began to form from minute variations in the mass density.

Ammonium levels in particular suffer from wide variations and sometimes high values.

So far, any impact that climate change may have had generally on regional rainfall cannot be distinguished from natural variations.

The visions that scryers say they see may come from variations in the medium.

The significance of such changes is uncertain, but their function appears to be different from similar variations in, for example, aphids.
