Creep data of Ni-based 19Cr-18Fe-3Mo-5Nb-Ti-Al superalloy (JIS NCF718-B) were obtained at 550°C to 750°C under 100MPa to 1000MPa and analyzed to determine the 100,000 h creep rupture strength. The tensile properties were also evaluated at room temp

This paper is concerned with the uniqueness of Kozono–Nakao’s bounded continuous $$L^{3}$$ -solutions on the whole time axis to the Navier–Stokes equations in 3-dimensional unbounded domains. When $$\Omega $$ is an unbounded domain, it is known

We give an alternative proof of a logarithmically improved Beale–Kato–Majda type extension criterion for smooth solutions to the Navier–Stokes equations in the whole space, which was shown by Fan et al. (2011). By our method, we can also establ

We shall find the weakest norm that satisfies the Brezis–Gallouet–Wainger type inequality, under some conditions. As an application of the Brezis–Gallouet–Wainger type inequality, we shall establish Beale–Kato–Majda type blow-up criteria
