Hm Convergence of the Second-Grade Fluid Equations to Euler Equations in ℝd
Discrete Dynamics in Nature and Society, 2020 In this paper, we investigate an approximation of the Euler equation by the second-grade fluid equations in ℝdd=2,3. The convergence in Hm of a sequence of solutions to the second-grade fluid equations in a uniform interval is proven as both the ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Magnetohydrodynamic approximation of the complete equations for an electromagnetic fluid
Tsukuba Journal of Mathematics, 1986 The authors give a singular limit theorem for the magnetohydrodynamic equations in two space dimensions, which are obtained as the limit of the complete equations for the electromagnetic fluid at the vanishing of the dielectric constant. They show convergence of the solutions of the complete equations to the solutions of the magnetohydrodynamic ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

The self power of a clamped circular plate. An analytical estimation
Archives of Acoustics, 2003 A low frequency approximation for the self power of a clamped crcular plate is presented in a form useful for some efficient numerical computations. The approximation is precise enough within nearly the whole low frequency range.
