The plastic limit of clays [PDF]

open access: yes, 2013
The plastic limit of soils was first described by Atterberg in 1911. The thread-rolling test was standardised at the US Public Roads Bureau in the 1920s and 1930s, and has subsequently become one of the standard tests of soil mechanics.

Quality improvement by application of a revised standard – feasibility studies on 2500 soundings

open access: yesActa Polytechnica CTU Proceedings, 2023
CPT is a geotechnical investigation method that, depending on the geology, has been proved to be an essential tool to establish the Geotechnical Design Model. However, doubt has been raised about the quality of the data.

Restorative Dentistry: Dental composite depth of cure with halogen and blue light emitting diode technology [PDF]

open access: yes, 2009
Objectives To test the hypothesis that a blue light emitting diode (LED) light curing unit (LCU) can produce an equal dental composite depth of cure to a halogen LCU adjusted to give an irradiance of 300 mWcm–2 and to characterise the LCU's light outputs.
