Process Analysis by Radioisotope Tracer Techniques

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...

Zn Radioisotope Production by Cyclotron

Natural Cu target was irradiated with proton beam in the energy range of 15 to 30 MeV at a beam current of 100 μA for 15 min. In this irradiation radioisotope of 62Zn was produced as a generator and then decayed to Cu radioisotope. The Cu is emitting β+ and known as PET radioisotope. Excitation function of Cu via Cu (p, 2n) Zn, Cu and Cu (d, 3n) Zn reactions were calculated using Alice and Taly...

Analysis of techniques for business process improvement

This paper is about identifying and analyzing techniques that can be used in a business process improvement (BPI) situation. To determine suitable techniques, the term BPI is defined and criteria are derived to analyze the usability of the selected techniques. Over 300 techniques from various improvement methods were reduced to those techniques which can be applied to help improve business proc...

Intracranial Hodgkin's disease shown by radioisotope scan.

Verified intracranial deposits of Hodgkin's disease are rare. Thus there was only one among 125 cases reported by John and Nabarro (1955). In the monograph by Williams, Diamond, Craver, and Parsons (1959) there were four among 1,992 cases. Todd (1967) reported two among 1,339 cases. The deposits are usually subdural, intracerebral metastases being exceptional. This rarity contrasts with the inc...
