Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution
To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent ...

Welcome to Net-Zero
For most people (and for most homes) the likelihood of going through a whole year spending next to nothing on energy is a goal that seems far out of reach. In fact, it is only relatively recently that insulation technologies, coupled with ...

Compactor Force and Energy Measurements
Two hand-operated compactors (a vibrating plate compactor and a rammer compactor) were instrumented to measure the dynamic contact force and energy transfer between compactor and soil. The instrumentation schemes, data acquisition techniques, and ...

Modified Testing Device to Evaluate <i>MR</i> Properties on Fly Ash Treated Subgrade Soil
The need to obtain reliable resilient modulus (MR) for fly ash treated subgrade soil in pavement thickness design in Taiwan prompted the modification of the existing standard testing device. In the modified device, a load cell and two linear ...

Introduction to a New Apparatus for Hydraulic Fracturing Tests
A new apparatus for hydraulic fracturing tests, on which the seepage and force boundary conditions can be controlled strictly, is briefly introduced here. Some test results obtained by using this apparatus are presented as an example. These results ...

An Alternative to the Cathead and Rope for the Standard Penetration Test
Previous studies by the authors have found that a cathead and rope when used to perform standard penetration tests (SPT) have resulted in energies reaching the striker plate or anvil substantially less than those resulting from a complete or 100% ...
