The thermal conductivity of stoichiometric CeO 2 was determined through measurement expansion from 313 to 1723 K, diffusivity 298 1473 and specific heat capacity 1373 K. then calculated as the product density, diffusivity, capacity. found obey an ( A + BT ) −1 relationship with = 6.776×10 −2 m·K·W B 2.793 × 10 −4 m·W . Extrapolations applied models were made provide suggested data for capacity, up Results measurements agreed well limited low‐temperature available in literature. values...
Numerical methods are used to investigate the steady two-dimensional motion of a viscous incompressible fluid past flat plate finite breadth at zero incidence uniform stream. Before application numerical techniques, governing partial differential equations for stream function and vorticity reduced ordinary by an adaptation normally solve Oseen's linearized equations. The complete range Reynolds number R is considered, from indefinitely small large. All results intended represent solutions...
Fundamental understanding of the electronic, chemical, and structural properties uranium oxides requires synthesis high-crystalline-quality epitaxial films different polymorphs one material or phases with various oxygen valence states. We report growth single-phase UO2, α-U3O8, α-UO3 thin using pulsed laser deposition. Both partial pressure substrate temperature play critical roles in determining crystal structure oxide films. X-ray diffraction Raman spectroscopy demonstrate that are single...
Microspectrophotometry with the DNA-localizing fluorochrome 4′,6 diamidino-2-phenylindole was used to estimate nuclear genome sizes in nine species representing two orders of Florideophycidae. Estimated 2C DNA spermatial contents these taxa are range 0.22–2.85 pg. Carpospore volume estimates determined by an image processing system for 24 and geographical isolates four Florideophycidae indicate mean ranges 3644–233,210 μm3 individual species, i.e. about magnitude. Estimates carpospore...
High-frequency plane sound waves in ideal gases with internal dissipation are discussed. Particular applications to dissociating diatomic and displaying vibrational relaxation considered. A criterion the form of an inequality is derived for validity high-frequency approximation asymptotic analysis developed.
In this paper the thermoelastic stability of a three-dimensional body subject to deformation—temperature constraint is examined with reference Ericksen’s [7] theory for unconstrained materials. It shown that sufficient conditions infinitesimal are unattainable finite bodies if temperature dependent. This general result illustrated by considering dynamic slab, initially at rest uniform temperature, in respect one-dimensional thermomechanical perturbations satisfying ‘dead loading’ boundary on...
