Calibration and Reliability of the Rebound (Schmidt) Hammer Test [PDF]
Civil Engineering and Architecture, 2013 One of the most widely spread techniques to estimate the compressive strength of concrete is the rebound hammer test, also known as Schmidt Hammer test. In spite of a large number of scientific works trying to calibrate the test, to identify the parameters affecting its results and to estimate its reliability, the original Schmidt curve is still ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 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.
