In this article, we consider 2D second grade fluid equations in exterior domain with Dirichlet boundary conditions. For initial data $\boldsymbol{u}_0 \in \boldsymbol{H}^3(\Omega)$, the system is shown to be global well-posed. Furthermore, for arbitrary $T > 0$ and $s \geq 3$, prove that solution belongs $L^\infty([0, T]; \boldsymbol{H}^s(\Omega))$ provided $\boldsymbol{u}_0$ $\boldsymbol{H}^s(...

The objective of this paper is to analyze the influence thermo-diffusion on magnetohydrodynamics (MHD) flow fractional second grade fluid immersed in a porous media over an exponentially accelerated vertical plate. In addition, other factors such as heat absorption and chemical reaction are used problem. More exactly, model has been developed using generalized Fick’s Fourier’s laws. Caputo-Fabr...

Currently, about 50% of patients with metastatic renal cell carcinoma (mRCC) receive a second-line therapy. Therefore, the choice at each subsequent treatment line remains an important issue. In this retrospective study, we sought to identify pretreatment clinical parameters that could predict the likelihood of a patient receiving a second-line therapy. One hundred and sixty-one mRCC patients w...

Grade retention is still common practice in some countries though longstanding experience tells us that it is a highly criticised practice for its unclear benefits, its important costs for the educational systems and its relation with school dropout. Therefore, the aim of the present study is to analyse which variables increase the probability of being retained in primary education differentiat...

Introduction The aim of this study was to investigate school contextual effects on daily tobacco smoking, heavy alcohol use and hashish use among adolescents, using multilevel analyses adjusting for individual-level factors. Methods The 2012 public health survey among adolescents in Skåne includes pupils in ninth grade in primary school (predominantly 15-16 years old) and second grade in seco...
