Helium-3 of the airway tree, locate unventilated defects, measure the alveolar oxygen partial pressure, and measure the ventilation/perfusion ratio. This technique may be critical for the diagnosis and treatment management of chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), emphysema, cystic fibrosis, and asthma. Production, sales and distribution of helium-3 in the United States are managed by the US Department of Energy (DOE) Isotope Program. Virtually all helium-3 used in industry today is produced from the radioactive decay of tritium. Tritium is a radioactive isotope of hydrogen and is typically produced by bombarding lithium-6 with neutrons in a nuclear
Tritium (programming language) transformation language. Much of this was based on his prior experience porting Wikipedia’s desktop website to the mobile web. Open Tritium is the open source implementation of the Tritium language. It was presented at O'Reilly Open Source Convention 2014 and the compiler is implemented in Go. Tritium takes as input HTML, XML, or JSON documents and outputs HTML, XML, or JSON data that has been transformed according to the rules defined in the Tritium script. Like JQuery, idiomatic Tritium code is structured around selecting a collection of elements via a CSS or XPath selector and then chaining a series of
