The costs of training, licensing and security for agencies using the nuclear density gauge (NDG) have become increasingly onerous for public engineering agencies, leading them to seek less expensive alternatives to conduct compaction testing. The study focused on three comparators: difference in ...

It is well-known that the nuclear density test has the advantage of rapid application; nevertheless, this method gives approximate results that should be correlated with a more precise technique, such as sand cone testing. The data at hand are first subjected to statistical analyses. Next, ...

Immunofluorescent staining for von Willebrand factor (VWF), albumin (ALB)-positive cells, and hepatocyte nuclear factor-4α (HNF-4α) revealed the obvious infiltration of capillaries and liver parenchymal cells (LPC) within the A-spCS sponges, respectively. The dashed line represents the interface...
The nuclear method is currently the preferred technology for field measurement of water content and dry density in geotechnical engineering. However, the nuclear method has been found to give inaccurate results when used on stabilized soils. Researchers at Purdue University developed a procedure to ...
