An unusual appearing gingival amalgam pigmentation (amalgam tattoo) that completely surrounded the maxillary right first premolar in a 13-year-old boy is presented. Because of the wide distribution and apparent clinical progression of the discoloration, an excisional biopsy was performed. The histopathologic diagnosis of amalgam pigmentation was confirmed(More)
1. An enzymatic assay for microsomal acyl-CoA: cholesterol acyltransferase (ACAT) activity in chicken hepatic tissues was developed using silicic acid chromatography. 2. ACAT activity was increased in response to liver cytosolic protein preparations suggesting the presence of cytosolic modulators of the enzyme. 3. Fractions containing low molecular weight(More)
This paper explores combining functional modeling and biomimetic design. Observed benefits of applying functional modeling to biomimetic design include a more complete, systematic modeling that reveals additional aspects of biological phenomena to be exploited. Incorporating biological phenomena into a function-based design repository requires that multiple(More)
Concept generation is at the heart of engineering design. This chapter considers an emerging tool set for generating concepts: function-based synthesis methods. To understand this tool set, the prominent methods in the field are reviewed and summarized, with a subset being investigated with more technical rigor. In addition to this review and investigation,(More)
