The increasing awareness of evposure to traditional paint strippers has prompted a search for altemativeproducts. Onegroup of such alternatives are formulations based on N-Methylpyrolidone (NMPkqn comparing NMP-based paint removers with more volatile products, the primary tradeoffs are stripping speed versus solvent inhalation, and product cost v e m wage cost. NMP-based paint removers work at ...

We have implemented a non-photorealistic rendering system which simulates the placement of paint/pencil/pastel strokes to produce representational artworks from digital images. The system is able to record an image of each paint stroke independent of the overall picture, in addition to some details about each stroke. Working with sets of paint strokes from paintings of different images, we inve...

This paper gives a detailed study on the performance of oil paint image filter algorithm with various parameters applied on an image of RGB model. Oil Paint image processing, being very performance hungry, current research tries to find improvement using parallel pattern library. With increasing kernelsize, the processing time of oil paint image filter algorithm increases exponentially.

This white paper discusses methods and findings from one of Novetta’s many approaches to vulnerability assessment: the fabrication of non-gelatinous artifacts for capacitive fingerprint sensors. We present methods of evaluating artifact performance relative to that of live presentations and gummy fingerprint artifacts. Two sets of artifacts are comprised of latex face paint or acrylic fabric pa...

A crack detection (CD) paint was applied to weld lines of a transverse rib welded joint specimen of a rolled steel for welded structures, and the effects of the paint on visual detection of fatigue cracks were evaluated by performing a fatigue test. Remarkable color development was observed in the CD paint when fatigue cracks propagated along the weld toe lines. At intervals in the fatigue test...

Day laborers in Chicago are often hired for hazardous jobs and have little access to basic health care. In this study, the researchers offered tetanus vaccinations and blood lead tests to workers waiting on street corners, who then completed a survey on hazardous job tasks (N = 92). All participants were male, 97% were foreign-born, and 93% had performed demolition and rehabilitation, window re...

We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across different sublayers, while it can be neglected within each of the sublayers. Based on this assumption, an efficient recursive procedure of assembling the layers is developed, which...

OBJECTIVES This study explored whether differences in environmental lead exposures explain the racial disparity in children's blood lead levels. METHODS Environmental sources of lead were identified for a random sample of 172 urban children. RESULTS Blood lead levels were significantly higher among Black children. Lead-contamination of dust was higher in Black children's homes, and the cond...
