Experimental and numerical analysis of polyurethane spraying materials as a compressible layer in deep soft rock tunnels

Journal of Rock Mechanics and Geotechnical Engineering
Polyurethane foam, when used as a compressible layer in deep soft rock tunnels, offers a feasible solution to reduce the support pressure on the secondary lining.

A Dilating Vortex Particle Method for Compressible Flow with Applications to Aeroacoustics [PDF]

, 2002
Vortex methods have become useful tools for the computation of incompressible fluid flow. In the present work, a vortex particle method for the simulation of unsteady two-dimensional compressible flow is developed and applied to several problems.

Compressibility of eleven inorganic materials

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1965
Volume compression measurements were made on eleven inorganic materials to a maximum pressure of 10,000 atm. Coefficients of the empirical equation -ΔV/V o =a(P -2000)+b(P-2000)2 were determined for the substances studied. Values of a in units of 10-6 atm-1 and b in units 10-10 atm-2 are as follows: Monel-a=0.62 b=0; Waspalloy-a=0.65, b=0; sapphire-a=0.

Large-eddy simulation of multi-component compressible turbulent flows using high resolution methods [PDF]

, 2008
The ability of a finite volume Godunov and a semi-Lagrangian large-eddy simulation (LES) method to predict shock induced turbulent mixing has been examined through simulations of the half-height experiment [Holder and Barton.

Compression therapy in venous diseases: current forms of compression materials and techniques

Advances in Dermatology and Allergology, 2020
Compression therapy (CT) is an established treatment method in chronic venous disease (CVD). The paper presents information on different CT forms with indications and contraindications based on expert consensuses from recent years. A high prevalence of CVD implies continuous development of compression materials, systems and techniques as well as ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
