The Onset of Rayleigh-Bénard-Marangoni Convection in a Ferromagnetic Fluid Layer
Abstract: This study examined the implications of magnetic boundary conditions, which are vertical in nature, on buoyancy and surface tension–driven ferrothermal convection (FTC) in a ferrofluid layer. While the upper surface is stress-free and susceptible to general thermal boundary issues, the bottom surface is stiff and insulating against temperature changes. The eigenvalue issue is solved analytically using the regular perturbation method and numerically using the Galerkin technique. According to analysis, raising …

Floating In-Situ Gel for Gastric Retention Delivery
Abstract: When taken orally, medications with a limited window of absorption in the gastrointestinal tract (GIT) are typically accessible to the extremities due to the partial release of the active component and the brief residence period at the absorption site. Because they prolong the duration of the drug's presence in the stomach, they are made with high density and have the capacity to swell. Because oral fluids go more quickly through …
