Erythrocyte radiolabelling: in vitro comparison of chromium, technetium, and indium in undamaged and heat damaged cells.
The stability of the commonly used red cell radio labels chromium-51, indium-(111 or 113m), and technetium-99m, within intact red cells and stroma and their distribution within the cell were compared in undamaged and heat damaged red cells in relation to the clinical use of heat damaged cells in the assessment of splenic function. Chromium-51 labelled haemoglobin both in undamaged and heat dama...
متن کاملComparison of local and global approaches to digital image correlation
Local and global approaches to digital image correlation are compared when the displacement interpolation is based upon bilinear shape functions (i.e., with fournode quadrilaterals). The resolution in terms of displacements and strains associated with both techniques are evaluated a priori and validated a posteriori by using series of images of real experiments. It is shown that global approach...
متن کاملAflatoxin contamination of cottonseed: comparison of pink bollworm damaged and undamaged bolls
Ajlatoxin contamination of cottonseedfrom bolls damaged by the pink bollworm (PB W) ,Pectinophora gossypiella (Saunders) , was comparedwith contamination ofcottonseedfrom undamaged bolls. Test bolls for comparative studies were collectedfrom similar positions on 25 plants in each ofthree harvests during a single season. Cottonseedproduced in PBW-damaged bolls were the predominant source ofajlat...
متن کاملDigital Image Compression
When several gray midtones are present, like a black and white photo, two values are no longer sufficient to encode all the possible gray intensities, and to each pixel must be associated a numerical value, proportional to the brightness of that point. Typical choices for these values fall in the ranges 0 31 or 0 255 (requiring respectively 4 and 8 bits for each pixel). This second kind of imag...
متن کاملOn the Use of Acoustic Emission and Digital Image Correlation for Welded Joints Damage Characterization
A series of tests have been conducted to investigate fatigue damage characterization in corroded welded steel plates using structural health monitoring (SHM) techniques. Acoustic Emission (AE) is a non-destructive testing (NDT) technique with potential applications for locating and monitoring fatigue cracks in service. In the present work, AE is implemented to characterize damage during crack e...
