An Apparatus for Preparing Isotopically Pure He
The helium extracted from gas wells consists predominantly of He but it also contains traces (a few parts in 10) of the other stable isotope, He. For many purposes, the presence of the He may be neglected. Commercial He, widely used for a variety of cryogenic and other technological applications, usually consists of the two isotopes in their natural relative abundances. There are certain other ...
متن کاملPreparing staff for information technology
There are many barriers in the path of Information Technology. The health system relies heavily on the visible print and paper culture, the Gutenberg Culture. Biscoe (1986) states, the key to overcoming this is the recognition that computers merely act as a mechanism for the storage and retrieval of information. Other factors that influence the health system stem from the fear of losing control...
متن کاملMethods of preparing spectrographically pure praseodymium salts
An ion-exchange process was developed for the separation of spectrographically pure praseodymium salts in kilogram amounts from commercially available concentrates. The application of either 0.5% or 0.1% citrate solutions as eluting agents was show to result in excellent separations of praseodymium from samarium, neodymium, and lanthanum when the mixed rare earths were eluted from Amberlite IR-...
متن کاملContinuous Flow Apparatus for Preparing Isotopically Pure He
A He isotopic purification cryostat has been developed, capable of sustained operation in continuous flow. Starting from a feedstock of helium of the natural isotopic ratio, He/He = x3 ≈ 10−7, it yields a purified product for which x3 < 5× 10−13 at a production rate of 3.3 STP m h−1. The isotopically purified He is being used for a variety of applications, including quantum evaporation experime...
متن کاملPreparing for COSMIC: Inversion and Analysis of Ionospheric Data Products
The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) is scheduled for launch in 2006. COSMIC will consist of six low earth orbiting satellites in planes separated by 24◦ to provide global atmospheric and ionospheric observations. One of the goals is to demonstrate near real-time processing of data products for numerical weather prediction and space weather applic...
