Characterization of volatile organic compounds at a roadside environment in Hong Kong: An investigation of influences after air pollution control strategies [PDF]

open access: yes, 2015
Vehicular emission is one of the important anthropogenic pollution sources for volatile organic compounds (VOCs). Four characterization campaigns were conducted at a representative urban roadside environment in Hong Kong between May 2011 and February ...

Volatile aldehydes in libraries and archives [PDF]

open access: yes, 2010
Volatile aldehydes are produced during degradation of paper-based materials. This may result in their accumulation in archival and library repositories. However, no systematic study has been performed so far.

Reconstructing PASCAL VOC [PDF]

open access: yes2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014
We address the problem of populating object category detection datasets with dense, per-object 3D reconstructions, bootstrapped from class labels, ground truth figure-ground segmentations and a small set of keypoint annotations. Our proposed algorithm first estimates camera viewpoint using rigid structure-from-motion, then reconstructs object shapes by

Conversion of chemical scrubbers to biotrickling filters for VOCs and H2S treatment at low contact times [PDF]

open access: yes, 2015
The purpose of this work was to evaluate the technical and economical feasibility of converting three chemical scrubbers in series to biotrickling filters (BTFs) for the simultaneous removal of H2S and volatile organic compounds (VOCs). The conversion of

The purpose shapes the vocative: Prosodic realisation of Colombian Spanish vocatives [PDF]

open access: yesJournal of the International Phonetic Association, 2018
The question of whether intonation contours directly signal meaning is an old one. We revisit this question using vocatives in Colombian Spanish (Bogotá). We recorded speakers' productions in three pragmatic conditions – greeting, confirmation-seeking, and reprimand – and compared proper names (vocatives) to situation-specific one ...

Real-time quantitative analysis of volatile products generated during solid-state polypropylene thermal oxidation [PDF]

open access: yes, 2013
Analysis of volatile organic compounds (VOCs) during PP thermal oxidation under three oxygen partial pressures (0%, 21% and 100% of atmospheric pressure) at 140 C was performed by proton transfer reaction coupled with Fourier transform ion cyclotron ...
