Measuring the strength of brittle materials by depth-of-penetration testing [PDF]

open access: yes, 2010
Based on an energy conservation model, the strength offered by a number of brittle materials has been calculated from depth-of-penetration (DOP) test results. Each material was completely penetrated by a tungsten carbide cored projectile of known kinetic

Penetration Resistance: PKR's Other Talent [PDF]

open access: yesImmunity, 2012
In this issue of Immunity, Irving et al. (2012) show that protein kinase R (PKR) regulates the cytoskeleton via an interaction with gelsolin. This alternative role for PKR prevents penetration of virions into the cell.

Soil Penetration Resistance after One-Time Inversion Tillage: A Spatio-Temporal Analysis at the Field Scale

open access: yesLand, 2020
Conservation agriculture may lead to increased penetration resistance due to soil compaction. To loosen the topsoil and lower the compaction, one-time inversion tillage (OTIT) is a measure frequently used in conservation agriculture.
