Observational Constraints and Some Toy Models in f(Q) Gravity with Bulk Viscous Fluid
Universe, 2022 The standard formulation of general relativity fails to describe some recent interests in the universe. It impels us to go beyond the standard formulation of gravity.

Continuum perspective of bulk viscosity in compressible fluids
, 2017 Kinetic theory and acoustic measurements have proven that the hulk viscosity associated with the expansion or compression effect cannot be ignored in compressible fluids except for monatomic gases.

Can Bulk Viscosity Drive Inflation [PDF]
, 1987 Contrary to other claims, we argue that, bulk viscosity associated with the interactions of nonrelativistic particles with relativistic particles around the time of the grand unified theory (GUT) phase transition cannot lead to inflation. Simply put, the

Bulk viscosity of a gas of massless pions [PDF]
Physical Review C, 2009 In the hadronic phase, the dominant configuration of QCD with two flavors of massless quarks is a gas of massless pions. We calculate the bulk viscosity (zeta) using the Boltzmann equation with the kinetic theory generalized to incorporate the trace anomaly.

Bulk viscosity of spin-one color superconductors [PDF]
, 2009 The bulk viscosity of several quark matter phases is calculated. It is found that the effect of color superconductivity is not trivial, it may suppress, or enhance the bulk viscosity depending on the critical temperature and the temperature at which the ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction This study investigated the safety and efficacy of single‐needle Rheocarna therapy for chronic limb‐threatening ischemia (CLTI) with wounds. Methods Six patients with CLTI involving ulcers unresponsive to revascularization underwent single‐needle Rheocarna treatment.

PHENOMENOLOGICAL THEORIES OF BULK VISCOSITY
Acta Physica Sinica, 1950 A relaxational bulk visco-elastic theory is formulated, leading to an equation recently assumed by Hall. A derivation is given of an expression for the coefficient of sound attenuation resulting from both shearing and bulk viscosities. The result is compared with classical hydrodynamics generalized in a manner similar to that given by Tisza.

Shear and Bulk Acceleration Viscosities in Simple Fluids
Physical Review Letters, 2022 Inhomogeneities in the velocity field of a moving fluid are dampened by the inherent viscous behaviour of the system. Both bulk and shear effects, related to the divergence and the curl of the velocity field, are relevant. On molecular time scales, beyond the Navier-Stokes description, memory plays an important role. We demonstrate here on the basis of

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
