¹¹¹In/Cd perturbed angular correlation (PAC) gamma spectroscopy was used to
study the point defect thermodynamics of tetragonal zirconia (t-zirconia).
PAC can be used to measure, among other things, oxygen vacancy defect
concentrations in t-zirconia. Higher than expected concentrations of oxygen vacancies in
undoped samples were found using PAC. It was...
Eighteen Ponderosa Pine (Pinus ponderosa Dougl.ex.laws) veneer flitches
were randomly selected and crosscut into paired flitches. Serpentine-end-matched
(SEM) joints were machined in the flitches, joint amplitude equal to the width in
one half of the paired flitch and joint amplitude equal to 2/3 width in the other half
