further choice, the bridge with lowest locants will remain uncombined. (b) The expanded base cycle may have as ring units only monocyclic rings, or where they have trivial names allowed by Organic Rules A-21.3, A-23.1, B-2, or D-Table IV in footnote 1, polycyclic rings are permitted. (c) When a bridge is combined with another part of the structure, the ring with the least number of atoms will b...

An inexpensive video data capture system

Digital mapping techniques are used increasingly in hydrology. One of the constraints on the application of those techniques is the digitizing process, which can be costly and time consuming. This paper describes the background and development of a low cost, easy-to-use system for digitizing maps, based on the use of a video camera as a scanner, and goes on to discuss the application of this sy...

An inexpensive, microcomputer-based, video densitometer for quantitating thin-layer chromatographic spots.

An inexpensive video densitometer based on an Apple II microcomputer using commercially available components was developed. The device was used to quantitate charred lipid and colored spots on thin-layer chromatography plates. The method is useful for lipid samples weighing 0.1 to 4 micrograms on high-performance plates and 1 to 20 micrograms on ordinary plates. The software automatically corre...
