In this project, an AromaScan A32S electronic nose and a human panel at the Duke Taste and Smell Lab were used to evaluate the effectiveness of biofilters in reducing the malodors in the exhaust air from swine confinement facilities. Three experiments are reported: 1) detection threshold tests for the electronic nose and human panel for a significant component of swine slurry – acetic acid, 2) ...

Ahstraet-Axisymmetric deformations of a transversely isotropic, rigid/perfectly plastic target being penetrated by a long rigid cylindrical rod with an ellipsoidal nose have been analyzed. The deformations of the target appear steady to an observer situated at the penetrator nose tip. The contact between the target and the penetrator is assumed to be smooth. Computed results show that the defor...

The nematode C. elegans senses head and nose touch using multiple classes of mechanoreceptor neurons that are electrically coupled through a network of gap junctions. Using in vivo neuroimaging, we have found that multidendritic nociceptors in the head respond to harsh touch throughout their receptive field but respond to gentle touch only at the tip of the nose. Whereas the harsh touch respons...

abstract        background and objective: staphylococcus aureus is the most common and important infectious agent. this bacterium can enter the bloodstream and cause some complications in the intensive care unit (icu).this organism can frequently be found in the nose and transmitted by the carriers. this study aimed to determine the efficiency of eradicating s. aureus from the nose of icu perso...

currently, nondestructive quality evaluation of various agricultural products are being developed and used. in this study, application of an electronic nose system for the quality assessment of kiwifruit (abbot variety) is used. electronic nose system coupled with artificial neural network (ann) and principal component analysis (pca) techniques was able to classify unripe, half-ripe, ripe, over...

IMPORTANCE Facial asymmetry is frequently detected in patients who are seeking rhinoplasty for a deviated nose, and its presence often leads to failure to create a straight-looking nose. OBJECTIVE To analyze the frequency and characteristics of facial asymmetry in patients with a deviated nose and to identify representative parameters to describe types and severity of facial asymmetry. DESI...
