The autogenous shrinkage of alkali-activated slag (AAS) is significantly higher than that of ordinary Portland cement (OPC).The higher tuner signal wire risk of concrete cracking due to autogenous shrinkage is a critical drawback to wider use of this promising alternative binder.The effect of CaO content on the autogenous shrinkage of AAS mortar wa
This paper examines experimentally and analytically the lateral vibrations of a Jeffcott rotor running at various unbalance states.Using a Bently Nevada RK-4 rotor kit, three states of eccentric mass unbalance were assumed in this study: 0.4g, 0.8g and 1.2g.Measurements of the startup data and the steady state data at rigid and flexible rotor condi
The presence of impurities in roasted ground coffee interferes with its quality.This Systematic Literature Review (SLR) aimed to identify and evaluate the different types of analytical techniques published in the last 20 years for the detection of adulterants in roasted coffee.The SLR was performed on StArt software ORG TURPENTINE OIL in three stag
Abstract Background The ecological importance of deadwood is widely acknowledged, however popular forestry practices may reduce deadwood from a site, and most European forests now fall below recommended targets, putting deadwood-associated species at risk.There is increasing evidence that earthworm species which live in alternative habitats such as
