Tracer Study In an Urban Valley

Journal of the Air Pollution Control Association, 1968
Results of a series of nighttime tracer experiments conducted during the Autumn of 1966 in the industrialized valley of Johnstown, Pa., are discussed. Quite atypical meteorology and dispersion occur within a classical drainage flow framework. An urban heat island effect is observed creating uniform temperature and wind structures within a layer of air ...

Ferrokinetic studies with stable isotopes as tracers

Medical Physics, 1987
A methodology for ferrokinetic studies based on the administration of iron stable isotopes was developed. Fractional plasma clearance and intestinal iron absorption in rabbits were determined using the double tracer technique. Three rabbits were given 58Fe solution intravenously and about 40 min later 57Fe solution orally.

Schistosoma mansoni: Tracer studies in mice

Experimental Parasitology, 1978
Abstract Mice with patent Schistosoma mansoni infections were injected via the tail vein with peroxidase and Thorotrast, and the ingestion of these tracers by the worms was followed over time. Both tracers are found initially in the crypts of the dorsal tegument of the male; however, the disappearance of the peroxidatic activity from the crypts ...

Problems in the Analysis of Dynamic Tracer Studies

Clinical Science, 1978
The identity of the body is not dependent on the persistence of the same material particles … during life, by the process of eating and digesting, the body undergoes perpetual changes. St Thomas Aquinas, quoted by Hevesy (1962).

Diagnostic Studies with Radioactive Isotope Tracers

Radiology, 1952
The technical utilization of radioactive isotopes for diagnostic procedures has followed a somewhat different line of development at Harper Hospital (Detroit) from that in many other institutions. While numerous details have been reported and some of them have been demonstrated before this Society previously, we would like at this time to present the ...

Tracer Studies

2011
This chapter introduces Tracer Study methodology, a cost-effective, capacity building tool for evaluating the operations and effectiveness of Virtual Communities of Practice (VCoPs). We make the argument that a VCoP is a dynamic, continually evolving entity, whose characteristics distinguish it in important ways from naturally occurring or purposively ...

RADIOIODINE TRACER STUDIES IN THIOCYANATE MYXEDEMA*

The Journal of Clinical Endocrinology & Metabolism, 1951
LTERATIONS in the function of the thyroid gland associated with the administration of potassium thiocyanate have been recognized clinically for a number of years. In 1936 Barker (1) observed 3 patients in whom during treatment with potassium thiocyanate “peculiar myxedematous swelling of the tissues of the face, orbital areas, and cervical region ...

A Method of Study of Radioactive Tracer Kinetics

IEEE Transactions on Biomedical Engineering, 1979
This paper presents an approach to the problem of estimating the number of exponential functions and the pertinent parameters in the output of a radioactive tracer kinetic process. In particular, application of a criterion called an information theoretical criterion (AIC) for the estimation of the number of exponential functions is proposed; AIC was ...
