Production of sodium alpha olefin sulfonates from a variety of normal alpha olefin blends has been studied at the pilot plant scale. Results for the sulfonation, neutralization, and hydrolysis of commercial grade C14, C1416, C1418, and C1224 normal alpha olefins are presented, and the application of a new surfactant drying technology for producing ultra-concentrated AOS is discussed. Physical p...

The feasibility of an electro-Fenton process to treat tylosin (TYL), a non-biodegradable antibiotic, was examined in a discontinuous electrochemical cell with divided cathodic and anodic compartments. Only 15 min electrolysis was needed for total tylosin degradation using a carbon felt cathode and a platinum anode; while 6 h electrolysis was needed to achieve high oxidation and mineralization y...

That class of methods for treating turbulence gathered under the banner of large eddy simulation is poised to enter mainstream engineering practice. There is a growing body of evidence that such methods offer a significant stretch in industrial capability over solely Reynolds-averaged Navier-Stokes (RANS)-based modelling. A key enabling development will be the adaptation of innovative processor...

Myoclonic contractions that may occur after hypoxia might be related to post-hypoxic status epilepticus (PHSE) or Lance Adams syndrome (LAS). It is important distinguish these two myoclonic conditions in terms of treatment and prognosis. In the literature, both PHSE LAS have not been reported pediatric age group including adolescents. Here we report an adolescent case with chronic renal failure...

We establish anomalous inertial range scaling of structure functions for a model of advection of a passive scalar by a random velocity field. The velocity statistics is taken gaussian with decorrelation in time and velocity differences scaling as |x|κ/2 in space, with 0 ≤ κ < 2. The scalar is driven by a gaussian forcing acting on spatial scale L and decorrelated in time. The structure function...

We describe how the Borel summability of a divergent asymptotic expansion can be expanded and applied to nonlinear partial differential equations (PDEs). While Borel summation does not apply for non-analytic initial data, the present approach generates an integral equation (IE) applicable to much more general data. We apply these concepts to the three-dimensional Navier-Stokes (NS) system and s...

For jets, large eddy resolving simulations are compared for a range of numerical schemes with no subgrid scale (SGS) model and for a range of SGS models with the same scheme. There is little variation in results for the different SGS models, and it is shown that, for schemes which tend towards having dissipative elements, the SGS model can be abandoned, giving what can be termed numerical large...
