Existence of solutions to singular elliptic equations with convection terms via the Galerkin method
In this article, we use the Galerkin method to show the existence of solutions for the following elliptic equation with convection term $$ - Delta u= h(x,u)+lambda g(x, abla u) quad u(x)>0 quad ext{in } Omega, quad u=0 quad ext{on } partial Omega, $

Magneto-Hydrodynamic Convection in Porous Media: the effect of Vadasz inertia term
Magnetohydrodynamics (MHD) concerns with a fluid which is immersed and moves in a magnetic field. Accounting for the Lorentz force rise up actions between the fluid and the magnetic field: the fluid velocity influences the magnetic field and viceversa.In

On the stability of the equation with a partial boundary value condition
The degenerate parabolic equation with a convection term is considered. Let Ω be a bounded domain with C2 $C^{2}$ smooth boundary and d(x)=dist(x,∂Ω) $d(x)=\operatorname{dist}(x, \partial\Omega)$ be the distance function from the boundary.

THE ROLE OF MACROSCOPIC TURBULENT DIAMAGNETISM IN ENSURING LONG-TERM STABILITY OF SUNSPOTS
We investigated the role of macroscopic turbulent diamagnetism in ensuring the long-term stability of the equilibrium state of the sunspots. The physical meaning of macroscopic diamagnetism of turbulent plasma is expulsion of a large-scale magnetic field

Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐

Nonlinear Robin problems with unilateral constraints and dependence on the gradient
We consider a nonlinear Robin problem driven by the p-Laplacian, with unilateral constraints and a reaction term depending also on the gradient (convection term). Using a topological approach based on fixed point theory (the Leray-Schauder alternative

The effects of Vadasz term, anisotropy and rotation on bi-disperse convection
The onset of thermal convection in a uniformly rotating and horizontally isotropic bi-disperse porous medium, taking into account the Vadasz term, is investigated.
