Abstract: Computer-aided diagnosis techniques may be combined with dual-energy radiography techniques to provide enhanced computer-aided diagnosis of, for example, lung nodules.

Abstract: A substrate cassette having a conventional form, an open container having an upper entrance and a narrow lower opening formed by two side panels and two end panels. A preferred embodiment includes a train of substrate alignment channels on the inner surfaces of the two side panels, each channel is U shaped and having planar surface with a left surface, a right surface, and a bottom surface. An arcuate curbing member disposed on a left surface in each of the substrate alignment channels. The arcuate curbing member includes a top end with a thinner sloped profile facing the upper open entrance of the cassette allowing a substrate to slide through and under a stepped lower end.

Abstract: A cleaning agent which provides effective solvency for a broad range of tasks and exhibits high flash point is disclosed. This cleaning agent comprises a C1-C4 ester of a C6-C20 fatty acid or a mixture of such esters having a total unsaturation of not more than 60 percent and/or a total saturation of not less than 40 percent or an iodine value of not more than 70. The fatty acid is preferably lauric acid or a mixture of fatty acids comprising lauric acid and not more than 60 percent unsaturated fatty acids and/or not less than 40 percent saturated fatty acids. Meanwhile, the C1-C4 ester is preferably methyl ester, butyl ester, isopropyl ester or a mixture thereof.
