Radioactive Tracer Technique in Biology

Industrial Flotation Process Modelling : Rtd Measurement by Radioactive Tracer Technique

The residence time of liquid and solid was determined in flotation banks of mechanical cells and flotation columns at Salvador Division, Codelco-Chile. The estimation was developed from residence time distribution (RTD) measurements using radioactive tracers. Results allowed the estimation of effective pulp volumes in flotation banks and columns. It was found that industrial flotation banks are...

Radioactive Tracers in Biology

Everybody talks about the atom, but few have more than a Sunday supplement knowledge of the simpler aspects of nuclear phenomena. The author, M.D. and Ph.D., and a member of the staff at Brookhaven, treats the story of the atom from its earliest historical conceptions to its possibilities in future war and peace. The style is of the simplest; no previous familiarity with mathematics or physics ...

combined methylene blue dye and radioactive tracer technique for sentinel lymph node localization in early breast cancer

background : sentinel lymph node biopsy is a technique used to identify the axillary node most likely to contain tumor cells that have metastasized from a primary carcinoma of the breast. this technique provides accurate staging with fewer complications than axillary dissection and may result in decreased costs. we designed the present study to determine the accuracy and success rate of a combi...

Radioactive tracer techniques in the sequencing of glycoprotein oligosaccharides.

Complete sequencing of the oligosaccharide units of glycoproteins can be performed by conventional physical techniques if nanomole quantities of pure molecules are available. However, isolation of sufficient quantities of a glycoprotein may not be technically feasible (e.g., the analysis of biosynthetic intermediates, or rare molecules). Alternatively, partial structural analyses may answer the...
