Abstract Using mathematical modeling and computational analysis, this study aims to examine the peristaltic blood flow of a non-Newtonian material in tapered channel with radiative heat flux response mechanisms. By utilizing long-wavelength approximation, ignoring wave number, performing under conditions low Reynolds closed form solutions for velocity, temperature, concentration fields are achi...

We discovered that hemoglobin emits high energy Soret fluorescence when two-photon excited by the visible femtosecond light sources. The unique spectral and temporal characteristics of hemoglobin fluorescence were measured by using a time-resolved spectroscopic detection system. The high energy Soret fluorescence of hemoglobin shows the spectral peak at 438 nm with extremely short lifetime. Thi...

These results agree in form with the results for nonelectrolytes.6 The important new features for electrolytes are (1) the present approach is considerably improved in simplicity and a...

Effects of some thermo-physical parameters on free convective heat and mass transfer over a vertical stretching surface at lowest level of heat energy in the presence of suction is investigated. The viscosity of the fluid is assumed to vary as a linear function of temperature and thermal conductivity is assumed constant. A similarity transformation is applied to reduce the governing equations i...

The role of the protein structural change monitored by absorption band shifts following flash photolysis of CO from myoglobin is discussed in terms of structure-function relationships. Evidence is presented that the Soret band shift does not depend primarily on the covalent linkage of the heme iron to the protein by using the mutation H93G(L) in which the proximal histidine 93 is replaced by gl...

We studied the thermal diffusion behavior of hexaethylene glycol monododecyl ether (C12E6) in water by means of thermal diffusion forced Rayleigh scattering (TDFRS) and determined Soret coefficients, thermal diffusion coefficients, and diffusion constants at different temperatures and concentrations. At low surfactant concentrations, the measured Soret coefficient is positive, which implies tha...

The heat and mass transfer characteristics of natural convection about a horizontal surface embedded in a saturated porous medium subject to variable viscosity are numerically analyzed, by taking into account the diffusion-thermo (Dufour) and thermal-diffusion (Soret) effects. The governing equations of continuity, momentum, energy and concentration are transformed into nonlinear ordinary diffe...

The paramagnetic feature of ferrofluid allows it to be utilised in electronic devices and improvise fluid circulation transformer windings. Hence, the present article aims conduct numerical study boundary layer flow along with Stefan blowing, velocity thermal slip, Soret effects within stagnation region over a stretching/shrinking surface. governing equations were solved numerically using bvp4c...
