Evolution of weak discontinuity in a van der Waals gas
Ain Shams Engineering Journal, 2015 In this article, the Lie symmetries analysis that leaves the system of partial differential equations (PDEs), governed by the one dimensional unsteady flow of an isentropic, inviscid and perfectly conducting compressible fluid obeying the van der Waals ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Particle Ratios in a Multicomponent Nonideal Hadron Resonance Gas
Advances in High Energy Physics, 2023 We have considered formation of a multicomponent nonideal hot and dense gas of hadronic resonances in the ultrarelativistic heavy ion collisions. In the statistical thermal model approach, the equation of state (EoS) of the noninteracting ideal hadron ...

Van der Waals' equation and nucleation theory [PDF]
European Journal of Physics, 1993 The assumptions and detailed predictions of Van der Waals' equation and of classical nucleation theory in relation to homogeneous condensation and cavitation are discussed. The predictions of both can be expressed in terms of reduced variables, relative to those at the critical point, and display remarkable quantitative similarity over a wide ...

FEBS Open Bio, EarlyView.Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

VERTICAL PROFILE OF DENSITY IN A VAN DER WAALS ATMOSPHERE IN NATAL CITY
Holos, 2019 The van der Waals state equation for atmosphere is determined from the critical temperature and critical pressure of the air gases. The meteorological radiosonde measures atmospheric pressure, temperature, and other meteorological variables, at several ...

3D gravity and non-linear cosmology
, 2005 By the inclusion of an additional term, non-linear in the scalar curvature $R$, it is tested if dark energy could rise as a geometrical effect in 3D gravitational formulations.
