Effects of Electrical Boundary Configurations on Magnetohydrodynamic Flow and Heat Transfer in a Liquid Metal-filled Annulus [PDF]
This numerical study investigates magnetohydrodynamic (MHD) flow and heat transfer for liquid metals within a cylindrical annulus subjected to a radial magnetic field.

Pressure Loss Estimation of Three-Phase Flow in Inclined Annuli for Underbalanced Drilling Condition using Artificial Intelligence [PDF]
Underbalanced drilling as multiphase flow is done in oil drilling operation in low pressure reservoir or highly depleted mature reservoir. Correct determination of the pressure loss of three phase fluids in drilling annulus is essential in determination ...

Hyponormality on an annulus with a weight
In this work, we consider the hyponormality of Toeplitz operators on the Bergman space of the annulus with a logarithmic weight. We give necessary conditions when the symbol is of the form , where ψ and φ are analytic on the annulus .

Numerical investigation of horizontal magnetic field effect on the flow characteristics of gallium f
In the present numerical study, the effect of an external horizontal magnetic field on the natural convection of an electrically conducting molten metal (gallium) inside a vertical cylindrical crucible has been investigated.

The Skein Category of the Annulus
We construct the skein category $\mathcal{S}$ of the annulus and show that it is equivalent to the affine Temperley-Lieb category of Graham and Lehrer. It leads to a skein theoretic description of the extended affine Temperley-Lieb algebras. We construct an endofunctor of $\mathcal{S}$ that corresponds, on the level of tangle diagrams, to the insertion

Global algebraic Poincaré--Bendixson annulus for van der Pol systems [PDF]
By means of planar polynomial systems topologically equivalent to the van der Pol system we demonstrate an approach to construct algebraic transversal ovals forming a parameter depending Poincar'e-Bendixson annulus which contains a unique limit cycle for

ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Curling of a Heated Annulus [PDF]
We study the large-displacement behavior of a thin annulus subjected to thermal gradients. Following axisymmetrical deflections, the annulus buckles into a periodic mode shape, which eventually forms a number of a radial curls under sustained heating. We
