The University of Pennsylvania Smell Identification Test (UPSIT) is a test that is commercially available for smell identification to test the function of an individual's olfactory system. Known for its accuracy among smell identification tests it is considered to be one of the most reliable (r=.94) and trusted. [1]
A fragrance wheel also known as aroma wheel, fragrance circle, perfume wheel or smell wheel, is a circular diagram showing the inferred relationships among olfactory groups based upon similarities and differences in their odor. [1] The groups bordering one another are implied to share common olfactory characteristics.

The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
According to the American Journal of Emergency Medicine, nearly 200,000 adults were treated in emergency rooms for snow-shovel-related accidents from 1990 to 2006, and more than 1,600 deaths were ...
"Lake-effect snow develops when cold air moves over a relative. When lake-effect snow hits regions of the Great Lakes during late fall and winter, you start to hear meteorologists use terms like ...
Snow accumulation on ground and in tree branches in Germany Snow blowing across a highway in Canada Spring snow on a mountain in France. Classifications of snow describe and categorize the attributes of snow-generating weather events, including the individual crystals both in the air and on the ground, and the deposited snow pack as it changes over time.
