The vibration theory of smell proposes that a molecule's smell character is due to its vibrational frequency in the infrared range. This controversial theory is an alternative to the more widely accepted docking theory of olfaction (formerly termed the shape theory of olfaction), which proposes that a molecule's smell character is due to a range of weak non-covalent interactions between its ...
The DeGennaro Lab seeks to determine the odors and olfactory receptors that contribute to host detection in mosquitoes, analyze nectar-seeking behavior and examine vector ecology. [3] DeGennaro also intends to establish a model for coral symbiosis and chemosensation using the upside-down jellyfish, Cassiopea xamachana , in order to study new ...
Aromachology is a relatively new science that explores positive feelings induced by odors far from any holistic or healing process. The term covers both natural and synthetic scents. The term aromachology is sometimes mistaken by companies with several other terms such as "essential oils" or "aromatherapy" as marketing phrases.
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 ...
In all industries, odor assessment is usually performed by human sensory analysis, by chemosensors, or by gas chromatography.The latter technique gives information about volatile organic compounds but the correlation between analytical results and mean odor perception is not direct due to potential interactions between several odorous components.
Monell was founded in 1968. The center's mission is to advance knowledge of the mechanisms and functions of the chemical senses. Knowledge gained from Monell’s research is relevant to issues related to public health, national health policy, and quality of life, including studies of obesity, diabetes, hypertension, pediatric health, occupational safety, environmental interactions, and ...
The New York Jets have once again been eliminated from the NFL playoff picture, pushing their league-worst drought to 14 seasons.
Domingos leads a research laboratory consisting of three postdoctoral research scientists, four graduate students and a research assistant.
