The effect of quasi-hydrostatic pressure upon the ferromagnetic ground state of magnetodielectric, double-
perovskite La₂ MnNiO₆ is investigated using x-ray absorption spectroscopy and diffraction measurements in a
diamond anvil cell. The Mn-O-Ni superexchange interaction that gives rise to ferromagnetism in this cation-
ordered structure is stable to at least 38...
Probability density functions (normal, lognormal, and three-parameter Weibull) were used to characterize strength data for three different types of metal-plate-connected wood truss joints (web at the bottom chord, tension splice, and heel). Modulus of elasticity (MOE) of the lumber used to fabricate the joints was also characterized. A probability-plot technique,...
A dual-mode engine has been developed where in one mode all engine cylinders fire normally, providing locomotion for the vehicle. In the other mode, one cylinder of the engine is used to compress low pressure residential natural gas (NG), in multiple stages, to a standard U.S. compressed natural gas (CNG)...
