Aortic ring abscess and mitral valve aneurysms complicating infective endocarditis have previously been described as surgical or autopsy findings. More recently, transesophageal echocardiography has been shown to be more sensitive than standard trans

The small differences in thermal expansion behavior between stoichiometric cordierites fabricated by different methods were measured using an XRD film method which records the complete diffraction patterns, at two temperatures, on one film. Examples

An N3− for O2− substituted oxynitride high-quartz material of essentially 1∶1∶2β-eucryptite composition was prepared and the effect of the nitrogen substitution on the thermal expansion of the crystal lattice studied. The substituted materia

The linear and the crystal-lattice thermal expansions of monoclinic CaO·Al2O3 were determined. The average coefficient α of linear thermal expansion between 22° and 1200°C is 7.7 × 10−6/°C. The crystal lattice expands anisotropically with exp
