CTX-M-131 is a natural Asp240Gly variant from the CTX-M-2 group detected in a Providencia rettgeri clinical strain from Brazil. Molecular analysis showed that blaCTX-M-131 was inserted in a complex class 1 integron harbored by a 112-kb plasmid, which has not been previously described as a platform for CTX-M-encoding genes with the Asp240Gly mutation. Steady-state kinetic parameters showed that ...

We present studies of the time-evolution of a twocomponent system of Bose-Einstein condensates (BEC) in the |F = 1, mf = −1〉 and |2, 1〉 spin states of Rb. The two condensates are created with a well-defined relative phase and complete spatial overlap. In subsequent evolution they undergo complex relative motions that tend to preserve the total density profile. The motions quickly damp out, leav...

We analyze a long-wavelength model of viscous entrainment from a nozzle and show that, when appropriate large-scale boundary conditions are imposed, the entrainment transition can become continuous. As the entrainment threshold is approached from above, the entrained steady-state spout becomes vanishingly thin compared to the nozzle radius and takes the form of a thin tendril emerging from a ba...

A cam driving a lumped inertia through a massless, elastic, slider-crank fol­ lower linkage with two concentrated masses located at the pin joints is considered. An iterative procedure taking the elasticity, damping, and changing geometry of the linkage into account is developed for synthesizing the cam profile to produce a desired output motion at a given design speed. The steady state solutio...

Recently it was shown that a wave profile which minimises total energy, elastic plus hydrodynamic, subject to the vorticity distribution being prescribed, gives rise to a steady hydroelastic wave. Using this formulation, the existence of non-trivial minimisers leading to such waves was established for certain non-zero values of the elastic constants. Here we show that when these constants are z...

this paper presents the steady state behavior and maintenance planning of the bleaching system in a paper plant. the paper plant comprises of various systems including feeding, chipping, digesting, washing, bleaching, screening, stock preparation and paper making, etc. one of the most important functionaries of a paper plant, on which quality of paper depends, is the bleaching system, where rem...

The combined effects of a uniform vertical magnetic field and a nonuniform basic temperature profile on the onset of steady Marangoni convection in a horizontal layer of micropolar fluid are studied. The closed-form expression for the Marangoni number M for the onset of convection, valid for polynomial-type basic temperature profiles upto a third order, is obtained by the use of the single-term...

We use a momentum balance to interpret numerical simulations of dense, steady, fully-developed inclined granular flows of spheres on an erodible base confined between flat frictional side walls. We observe an exponential profile of mean volume fraction in the direction perpendicular to the base and suggest a scaling for its characteristic length. We also predict volume fraction and mean velocit...

The effect of nonequilibrium solute trapping by a growing solid under rapid solidification conditions is studied using a phase-field model. Considering a continuous steady-state concentration profile across the diffuse solid-liquid interface, a new definition of the nonequilibrium partition coefficient in the phase-field context is introduced. This definition leads, in particular for high growt...

The relation between the safety factor profile, q, the electron transport and the bootstrap current is of crucial importance for predicting advanced scenarios in burning plasmas which will have dominant electron heating and small momentum input. In recent experiments in the Tokamak TCV, the full plasma current has been sustained with only off-axis co-current drive and bootstrap current. As soon...
