Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Study of a zirconium getter for purification of xenon gas

open access: yes, 2010
Oxygen, nitrogen and methane purification efficiencies for a common zirconium getter are measured in 1050 Torr of xenon gas. Starting with impurity concentrations near 10^{-6} g/g, the outlet impurity level is found to be less than 120*10^{-12} g/g for ...

A simple high-sensitivity technique for purity analysis of xenon gas

open access: yes, 2010
We report on the development and performance of a high-sensitivity purity-analysis technique for gaseous xenon. The gas is sampled at macroscopic pressure from the system of interest using a UHV leak valve. The xenon present in the sample is removed with

Condition inspections of residential property: a procedural framework [PDF]

open access: yes, 2002
Presents a procedural framework for the inspection of domestic property. A mechanistic task, such as sketching the site plan and roof plan, is advocated in order to achieve focus, familiarity and freedom to undertake the inspection alone.

Cutting arcs for torus links and trees

open access: yes, 2015
Among all torus links, we characterise those arising as links of simple plane curve singularities by the property that their fibre surfaces admit only a finite number of cutting arcs that preserve fibredness.
