Immersed Boundary Projection Method for Boundaries With Slip Velocities
A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Abstract Edible oils are essential dietary constituents that contribute as energy source, fatty acids and medium for fat‐soluble vitamins. High temperature during frying induces changes in the fatty acid profile of edible oils. The primary aim of this study is to investigate the influence of high temperature (230 ± 5°C) and duration of heating (0, 1, 2

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

ABSTRACT Bystander intervention is widely assumed to foster workplace inclusion, yet no studies have directly examined this relationship. Through abductive qualitative analysis of 53 interviews across two contrasting organisations—a consulting firm and a remote mine site—we investigate how bystander intervention relates to workplace inclusion for ...

Micellar and Solubilization Properties of Biological Surfactant Surfactin
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.
