Weapons Radiochemistry: Trinity and Beyond

PET tracers and radiochemistry.

This paper provides a brief review of the radiochemistry of radiopharmaceuticals used in positron emission tomography (PET). It includes some history of PET, the basic formation of radionuclides in a cyclotron target, the processing of the precursor molecules into a useful PET radiotracer and the clinical significance and outlook for PET radiotracers. This review is based on a series of recent ...

PET Radiochemistry and Radiopharmacy

References .......................................................................... 27 Abstract The vast majority of PET radiopharmaceuticals today are cyclotron produced. Carbon-11 (C), Nitrogen-13 (N), Oxygen-15 (O) products are created for in-house use only due to their short half-lives. The longer half-life of Fluorine-18 means that F-labeled PET radiotracers can be widely distributed. Pr...

Election and Trinity

ion (‘‘Seek God,’’ 69). It seems that McCormack subscribes to the older historiography among Barthians that has characterized Protestant orthodoxy as being cold, mechanical, speculative, and abstract; in other words, more influenced by Greek philosophy than biblical exegesis. A refutation of this characterization is offered by Richard Muller in ‘‘Calvin and the Calvinists, Part 2,’’ 148-51. 92 ...

Advaita and Trinity

essentia beyond the Trinity 2. i t is a differentiated unity, not because of different actions outwards, but because of inner relationships (relationes). Inner relationships mean that i t is Being in movement, that this Being is energy. Augustine tries to find analogies to show the nature of these intimate relationships. In this regard, the human soul and its experiences is most important to him :
