Ultrahigh Pressure Generation at High Temperatures in a Walker-Type Large-Volume Press and Multiple Applications

Engineering
Ultrahigh pressure generation at high temperatures is technologically challenging for large sample volumes. In this study, we successfully generated pressures of 37.3–40.4 GPa at 1900–2100 K in a Walker-type large-volume press (LVP).

Conditional and Conditioned Reasons

Utilitas, 2002
This paper is a brief reponse to some of Douglas Portmore's criticisms of our version of the agent-relative/agent-neutral distinction.In his interesting and helpful paper ‘McNaughton and Rawling on the Agent-relative/Agent-neutral Distinction’, Douglas Portmore criticizes our formalization of duties on the grounds that we have over-looked an important ...

Evaluation of the Homogeneity of Geochemical Reference Materials by Wavelength-Dispersive X-Ray Fluorescence Spectrometry Using 0.1 g Fusion Samples

Journal of Chemistry
Good homogeneity is a critical guarantee for the accuracy of certified reference material values. X-ray fluorescence spectrometry (XRF) is widely used for the homogeneity testing of geochemical reference materials due to its simple sample preparation and

Coupled Model of Heat and Mass Balance for Droplet Growth in Wet Steam Non-Equilibrium Homogeneous Condensation Flow

Energies, 2017
Because of the complexity of wet steam two-phase condensation flow, many problems remain to be solved. The important part of condensation theory—the calculation of the water droplet growth model in the transition zone—is not ideal; thus, it is necessary ...

Acoustic Emission Monitoring of Fatigue Crack Growth in Mooring Chains

Applied Sciences, 2019
Offshore installations are subject to perpetual fatigue loading and are usually very hard to inspect. Close visual inspection from the turret is usually too hazardous for divers and is not possible with remotely operated vehicles (ROVs) because of the ...
