EFFICIENCY FACTOR OF SUPPLEMENTARY CEMENTITIOUS MATERIALS: A STATE OF ART
The use of supplementary cementing materials is gradually increasing due to technical, economical, and environmental benefits. Supplementary cementitious materials (SCM) are most commonly used in producing ready mixed concrete (RMC). A quantitative understanding of the efficiency of SCMs as a mineral admixture in concrete is essential for its effective utilisation. The performance and effective...

15 صفحه اولInflammometry: the current state of play.
It is now 20 years since the late Freddy Hargreave and colleagues developed a valid, safe and feasible technique to assess airway inflammation using induced sputum. At around the same time Kjell Alving and colleagues reported that the concentration of exhaled nitric oxide (FENO) is raised in patients with asthma. There has since been huge research interest in these techniques over the last 20 y...
متن کاملThe Quantum Measurement Problem: State of Play
This is a preliminary version of an article to appear in the forthcoming Ashgate Companion to the New Philosophy of Physics. In it, I aim to review, in a way accessible to foundationally interested physicists as well as physics-informed philosophers, just where we have got to in the quest for a solution to the measurement problem. I don’t advocate any particular approach to the measurement prob...
