Localized in vivo 1H NMR detection of neurotransmitter labeling in rat brain during infusion of [1-13C] D-glucose

Resolved localized nuclear magnetic resonance (NMR) signals of 1H bound to 13C label in the carbon positions of glutamate C4, C3 and glutamine C4, C3, as well as in aspartate C3, lactate C3, alanine C3, γ,-aminobutyric acid C3, and glucose C1 were simultan ...

Low argon solubility in silicate melts at high pressure

Philippe Gillet, James Badro

The solubility of rare gases in silicate melts and minerals at high pressure is of importance for understanding the early history of the Earth and its present day degassing. Helium, neon, argon, krypton and xenon were originally incorporated into the Earth ...

Horizontal mixing in lakes

Alfred Johny Wüest

Horizontal mixing in the upper hypolimnion of lakes far from the boundaries was studied in lake basins with surface areas between 5 and 220 km(2) by observing the growth of the concentration distribution of the fluorescent dye sodium fluorescein (uranin). ...

Using deuterated trichloroethylene (TCE) in a tracer test to estimate the transport characteristics of a TCE plume

David Andrew Barry

A trichloroethene (TCE) plume has been identified in an unconfined sand aquifer in Perth, Western Australia. This is the first known major occurrence of groundwater contamination by chlorinated aliphatic compounds in Perth. A small-scale (ca. 13m), natural ...

Ventilation Efficiency Measurements in Sulzer Test Chamber

Claude-Alain Roulet

Measurements ith tracer gases were performed, together with more classical temperature and air velocity measurements, on various ventilation systems installed in the test chamber of Sulzer Infra, in Winterthur. The test chamber was arranged to simulate an ...

Improvements of actuators in teleoperators

The main feature of a bilateral Master-Slave servomanipulator is its "transparency", i.e. the operatr has virtually to feel as if his own hands were extended to the Slave on the spot of remote operation, i.e. inside a radioactive environment. To obtain thi ...

A simple method using tracer gas to identify the main air- and contaminant paths within a room

Claude-Alain Roulet, Raphaël Compagnon

The main air and contaminant flow paths or the spatial distribution of the age of air (or contaminant) in a room are of great interest to estimate the ventilation efficiency performance. A simple measurement method is presented, which consists to inject or ...

24Na and 99mTc Tracers Applied to the Characterization of Liquid-Solid Fluidized Bed and Hydraulic Transport Reactors

Albert Renken

For the characterization of fluidized bed- and hydraulic transport reactors, two radiotracer techniques have been developed permitting the study of mixing phenomena in flowing liquids as well as in beds of fluidized particulate solids. For labelling the aq ...
