Occupational exposure to nickel salts in electrolytic plating.
An occupational hygiene survey was made in 38 nickel plating shops in Finland and exposure to nickel was studied by means of biological measurements and, in three shops, by using air measurements. The average after-shift urinary nickel concentration of 163 workers was 0.16 mumol l.-1 (range 0.001-4.99 mumol l.-1). After the 1-5 week vacation the urinary nickel concentration was higher than the ...
متن کاملRecent research on nickel carcinogenesis.
Research on nickel carcinogenesis from 1975 to March 1980 is reviewed. Epidemiological studies have strengthened the evidence that workers in nickel refineries have increased risks of cancers of the nasal cavities and lungs. Clinical investigations have resulted in improved diagnosis, classification, and management of cancers of respiratory organs in nickel refinery workers. Carcinogenicity tes...
متن کاملVisual Appearance of Matte
All visual sensors, biological and arti cial, are nite in resolution by necessity. This causes the e ective re ectance of surfaces in a scene to vary with magni cation. A reectance model for matte surfaces is described that captures the e ect of macroscopic surface undulations on image brightness. The model takes into account complex physical phenomena such as masking, shadowing and interre ect...
متن کاملImproving alpha matte with depth information
In this paper, we propose an automatic alpha matting method that improves the quality of alpha matte using a depth camera. Depth camera obtains both visual and depth information of moving objects in real time. Our matting method improves existing natural alpha matting methods by adding depth information. Experimental results demonstrate that our matting method generates better results than the ...
متن کاملMatte Super-Resolution for Compositing
Super-resolution of the alpha matte and the foreground object from a video are jointly attempted in this paper. Instead of superresolving them independently, we treat super-resolution of the matte and foreground in a combined framework, incorporating the matting equation in the image degradation model. We take multiple adjacent frames from a low-resolution video with non-global motion for incre...
