Asymptotic solution for the Darcy-Brinkman-Boussinesq flow in a pipe with helicoidal shape [PDF]
We study the fluid flow and heat transfer in a helical pipe filled with a sparsely packed porous medium. Motivated by the engineering applications, pipe’s thickness and the distance between two coils of the helix have the same small order of magnitude ...

Effect of Thermal Undulations on the Bending Elasticity and Spontaneous Curvature of Fluid Membranes
We amplify previous arguments why mean curvature should be used as measure of integration in calculating the effective bending rigidity of fluid membranes subjected to a weak background curvature.

Fine Grid Numerical Solutions of Triangular Cavity Flow
Numerical solutions of 2-D steady incompressible flow inside a triangular cavity are presented. For the purpose of comparing our results with several different triangular cavity studies with different triangle geometries, a general triangle mapped onto a

ABSTRACT Ecological models explain social phenomena by assuming specific properties of the world an individual lives in. The evaluative information ecology model (Unkelbach et al. 2019) assumes two such properties: Positive information is more frequent (i.e., positivity prevalence), but negative information is more diverse (i.e., negativity diversity).

Analytical solution for the stationary model of pollutant propagation in an aquatic medium
This work presents a new analytical approach for solving pollutant dispersion problems along irregular-shaped water bodies. In this approach, the advection-diffusion equation is expressed in terms of orthogonal curvilinear coordinates, defined by the ...

Australia's Three System Approach to Mammographic Image Quality Assessment
Mammographic image evaluation in Australia remains constrained by the use of fragmented, subjective, and largely unevaluated systems. The continued use of the Perfect (P), Good (G), Moderate (M), Inadequate (I) (PGMI) image evaluation system (IES) framework despite concerns around its validity and reliability reflects a perceived practical utility and ...
