The stellar mass-to-light ratio gradient in SDSS $r-$band $\nabla (M_*/L_r)$ of a galaxy depends on its mass assembly history, which is imprinted morphology and gradients age, metallicity, initial function (IMF). Taking MaNGA sample 2051 galaxies with masses ranging from $10^9$ to $10^{12}M_\odot$ released DR15, we focus face-on galaxies, without merger bar signatures, investigate the dependenc...

We call a module M , quasi-catenary if for each pair of quasi-prime submodules K and L of M with K L all saturated chains of quasi-prime submodules of M from K to L have a common finite length. We show that any homomorphic image of a quasi-catenary module is quasi-catenary. We prove that if M   is a module with following properties: (i) Every quasi-prime submodule of M has finite quasi-height;...

In this paper, the concepts of derived sets and derived operators are generalized to $(L, M)$-fuzzy topological spaces and their characterizations are given.What is more, it is shown that the category of stratified $(L, M)$-fuzzy topological spaces,the category of stratified $(L, M)$-fuzzy closure spaces and the category of stratified $(L, M)$-fuzzy quasi-neighborhood spaces are all isomorphic ...

human t-cell lymphotropic virus type 1 , 2 (htlv-1, 2) is endemic in particular areas of the world in which it is associated with myeloid leukemia.in this study, we described the prevalence of htlv-1, 2 in myeloid leukemia and mycobacterium tuberculosis in iran. we have worked with tissue and blood samples for 2 years. these were the same samples which were positive for myeloid leukemia, mycoba...
