Steady-state enzyme kinetics is a cornerstone technique of biochemistry and related sciences since it allows the characterization quantification behaviour. Enzyme widely used to investigate physiological role enzymes, determine effects mutations characterize inhibitors. Well-known examples inhibitors treat diseases include anti-infectives (e.g., penicillin, clavulanic acid HIV protease inhibito...

Abstract. We study the steady state phase behavior of homogeneous, rigid, extended (polar) nematic polymers or nematic dispersions under imposed magnetic (or electric fields), in which the intermolecular dipole-dipole and excluded volume interaction as well as external field contribution are accounted for. We completely characterize the phase diagram for polar nematics with and without permanen...

Abstract The reaction rates of the beta processes for all particles at arbitrary degeneracy are derived, and an analytic steady state equilibrium condition μn = μp + 2μe which results from the equality of electron and positron capture rates in the hot electron-positron plasma with nucleons is also found, if the matter is transparent to neutrinos. This simple analytic formula is valid only if el...

This paper is concerned with the following Gierer-Meinhardt type systems subject to Dirichlet boundary conditions    ∆u− αu + u p vq + ρ(x) = 0, u > 0 in Ω, ∆v − βv + u r vs = 0, v > 0 in Ω, u = 0, v = 0 on ∂Ω, where Ω ⊂ R (N ≥ 1) is a smooth bounded domain, ρ(x) ≥ 0 in Ω and α, β ≥ 0. We are mainly interested in the case of different source terms, that is, (p, q) 6= (r, s). Under approp...

in this study the thermal conductivity and the volumetric heat capacity of non-newtonian fluids are investigated. these fluids find many applications in chemical, medical and food industries. they mostly have viscoelastic behavior and generally differ from newtonian fluids. two non-newtonian fluids, solutions of xanthan and carboxy methyl cellulose in water with various concentrations have bee...

In this paper, we revisit a diffusive Leslie–Gower predator–preymodel with Holling-type II functional responses and Dirichlet boundary condition. It is shown that multiple positive steady state solutions exist under certain conditions on the parameters, while for another parameter region, the positive steady state solution is unique and locally asymptotically stable. Results are proved by using...
