A Color Image Analysis System (CD-CWA) for the Quantification of Wound Healing in Multicenter Trials

The magnitude of error in estimating axial resistances was assessed using the diameters of xylem vessels of different shapes, measured using four different methods. Statistical analyses showed that the diameter measurements obtained using the different methods, were significantly different at the 0.001 level of significance. Using the Tukey test, the diameters obtained using the 'four axes' method were not significantly different from the actual diameters obtained using the Chromatic Color Image Analysis System. By using the 'Lewis' method for measuring the xylem diameter, axial resistance was overestimated by a factor of 1.6. Thus, the error caused by the method of measurement may partly explain why, in some studies, the estimated axial resistances have always been different from the measured resistances. The 'four axes' method is the simplest and most reliable and gives results very close to the actual diameters, compared with the other three methods.

Reclamation System

Much progress has been made in recent years towards the development of closed-loop foundry sand reclamation systems. However, virtually all work to date has determined the effectiveness of these systems to remove surface clay and metal oxide scales by a qualitative inspection of a representative sampling of sand particles. In this investigation, particles from a series of foundry sands were sized and chemically classified by a Lemont image analysis system (which was interfaced with an SEM and an X-ray energy dispersive spectrometer) in order to statistically document the effectiveness of a reclamation system developed by The Pangborn Company - a subsidiary of SOHIO.The following samples were submitted: unreclaimed sand; calcined sand; calcined & mechanically scrubbed sand and unused sand. Prior to analysis, each sample was sprinkled onto a carbon mount and coated with an evaporated film of carbon. A backscattered electron photomicrograph of a field of scale-covered particles is shown in Figure 1. Due to a large atomic number difference between sand particles and the carbon mount, the backscattered electron signal was used for image analysis since it had a uniform contrast over the shape of each particle.
