Cryogenic trapping for determination of odor concentration

Water Science and Technology, 2004
The sensory testing method applied under Japanese law to measure odor concentration has a lower detection limit of 10 in the specified Odor Index. To measure odor below the limit, a condensing procedure using solid sorbents (Tenax-TA, Unicarbon B and ...

Training with varying odor concentrations: implications for odor detection thresholds in canines

Animal Cognition, 2021
Detection dogs are required to detect trace quantities of substances, many times in the parts per billion or parts per trillion concentration range. Frequently, detection of trace quantities is not explicitly trained but rather assumed when dogs show proficiency at higher concentrations to which they are trained.

Intranasal Odorant Concentrations in Relation to Sniff Behavior

Chemistry & Biodiversity, 2014
AbstractKnowledge on how odorants are transported through the nasal cavity to the olfactory epithelium is limited. One facet of this is how the sniffing behavior affects the abundance of odorants transferred to the olfactory cleft and in turn influences odor perception.

Modular neural networks for estimating odor concentrations

2008 IEEE International Joint Conference on Neural Networks (IEEE World Congress on Computational Intelligence), 2008
The concentration estimation for multiple kinds of odors is regarded first as multiple two-class classification and then as multiple approximation problems, and solved by multiple single-output multi-layer perceptrons (MLPs) lined up in two parallel rows. A pair of MLPs in cascade is on behalf of a specified odor.

Regulation of Tentacle Length in Snails by Odor Concentration

Neuroscience and Behavioral Physiology, 2006
The upper tentacle of the snail, bearing the olfactory organ, produces complex movements when the snail explores a new environment. Tentacle trajectories were reconstructed in the presence and absence of odors using two simultaneous video recordings.

Relationships between odor properties and determination of odor concentration limits in odor impact criteria for poultry and dairy barns

Science of the Total Environment, 2018
Livestock odor properties have not been well understood and the role of hedonic tone (HT) in establishing appropriate odor impact criteria has not been investigated. Five odor properties, including odor concentration (OC), intensity (OI), HT, persistence, and character descriptor, were studied for odorous air from a commercial dairy barn, layer barn ...

MEASURING ODOR CONCENTRATION WITH AN ELECTRONIC NOSE

Transactions of the ASAE, 2001
The Adaptive Logic Network (ALN) software, a type of artificial neural network (ANN), was used to develop a function to convert the measurements of a commercially available electronic nose into odor concentrations. A data set was developed by evaluating odor samples with both an olfactometer and the electronic nose.
