Chamber for testing asbestos-containing products: validation and testing of a re-created chrysotile-containing joint compound.
We re-created 1960s-era chrysotile-containing joint compound (JCC) and compared its characteristics to a current-day asbestos-free joint compound (JCN). Validation studies showed that a bench-scale chamber with controlled flow dynamics, designed to quantify particulate emissions from joint compound...
Ring-opening-induced toughening of a low-permittivity polymer-metal interface.
Health risk among asbestos cement sheet manufacturing workers in Thailand.
Journal of the Medical Association of Thailand ... 92 Suppl 7:S115 (2009) PMID 20235362To assess asbestos exposure and calculate the relative risks of lung cancer among asbestos cement roof sheet workers and to predict the incidence rate of lung cancer caused by asbestos in Thailand. A cross-sectional study was conducted in four asbestos cement roof factories. Both area and personal a...
Experimental realization of a broadband bend structure using gradient index metamaterials.
Following the theoretical work on arbitrary waveguide bends using gradient-index and isotropic materials, a 90-degree bend structure is experimentally realized using artificial metamaterials. Broadband and low-loss unit cells, the I-shaped cells, are used in the laboratory prototype. Field mapping m...
Performance of a pilot-scale biotrickling filter in controlling the volatile organic compound emissions in a furniture manufacturing facilit...
A 0.75-m3 pilot-scale biotrickling filter was run for over 1 yr in a Spanish furniture company to evaluate its performance in the removal of volatile organic compounds (VOCs) contained in the emission of two different paint spray booths. The first one was an open front booth used to manually paint f...
Fixure-reduce method for the synthesis of Cu2O/MWCNTs nanocomposites and its application as enzyme-free glucose sensor
Cu(2)O/MWCNT (multi-walled carbon nanotubes) nanocomposites were successfully prepared in large quantities with a new fixure-reduction method under low temperature. The morphology and shape of the Cu(2)O/MWCNTs nanocomposites were characterized by field emission scanning electron mic...
The role of dispersion in the propagation of rotating beams in left-handed materials.
We theoretically study the role of dispersion in propagation of rotating beams in left-handed materials (LHMs). By modeling the rotating beam as a superposition of two rotating Laguerre-Gaussian beams with opposite chirality, same magnitude and different frequencies, we demonstrate that the rotation...
From computerized tomography data processing to rapid manufacturing of custom-made prostheses for cranioplasty. Case report.
Cranioplasty is a surgical repair of a structural or morphological deformity of the skull, involving the resection, remolding and displacement of the bones of the head. As it pertains to abnormal head shape, cranioplasty is an operative procedure aimed to fill a gap in the cranial theca or to replac...
Sub-diffraction-limited interference photolithography with metamaterials.
We present that an interference lithography technique beyond the diffraction limit can be theoretically achieved by positing an anisotropic metamaterial under the conventional lithographic mask. Based on the special dispersion characteristics of the metamaterial, only the enhanced evanescent waves w...
Defining stakeholder involvement in participatory design processes
A participatory approach could be used to implement work place or organizational improvements. However, the question is which participants should be involved and how. In this paper the theoretical involvement in different steps of a linear stepwise approach is described and compared with the latest...
