at present paper, we establish the existence of pullback $mathcal{d}$-attractor for the process associated with non-autonomous partly dissipative reaction-diffusion equation in $l^2(mathbb{r}^n)times l^2(mathbb{r}^n)$. in order to do this, by energy equation method we show that the process, which possesses a pullback $mathcal{d}$-absorbing set, is pullback $widehat{d}_0$-asymptotically compact.

the seedbed preparation and cereal residue present due to limit of maize (zea mays l.) growing period are a major challenge in double cropping after winter cereals in iran as: shahrekord. in this research, effects of various seedbed preparation methods and crop residuea managements on vegetative growth and yield of forage maize (ksc 704) were studied in a barley-maize double cropping during 200...

Simpson and Visser recently proposed a phenomenological way to avoid some kinds of space-time singularities by replacing parameter whose zero value corresponds singularity (say, $r$) with the manifestly nonzero expression $r(u)=\sqrt{{u}^{2}+{b}^{2}}$, where $u$ is new coordinate, $b=\text{const}>0$. This trick, generically leading regular minimum $r$ beyond black hole horizon (called ``blac...
