This research explored the effects of an angled magnetic field, Brownian motion, and thermophoresis on flow electrically conducting chemically reacting Casson nanofluid under influence Soret-Dufour mechanism. A set partial differential equations is generated by mode. The governing are solved numerically using spectral collocation method after being transformed to self-similar forms. effect vari...

We present measurements of the transient stage of Soret-driven convective instability. The sample is a diluted colloidal suspension of silica spheres in water with an unusually large negative Soret coefficient S(T). A large temperature gradient (heating from above) is rapidly applied over the sample, while a shadowgraph imaging technique provides images of the convective flow. From the processi...

Myoglobin from the dark muscle of sardine (Sardinella gibbosa) with the molecular weight of 15.3 kDa was isolated and characterized. The different myoglobin derivatives exhibited varying thermal unfolding characteristics. Deoxymyoglobin showed a single distinct endothermic peak at 74.5°C, whereas two transition temperatures were noticeable for oxymyoglobin (64.5°C and 78.4°C) and metmyoglobin (...

Placing a fluid mixture in temperature gradient can cause concentration gradients to build up, phenomenon called the Soret effect. The authors simulate this effect for of monomers and dimers, find contribution from internal degrees freedom dimers. Under some conditions sign is reversed.

Unsteady viscous two-dimensional magnetohydrodynamic micropolar flow, heat and mass transfer from an infinite vertical surface with Hall Ion-slip currents is investigated theoretically numerically. The simulation presented motivated by electro-conductive polymer (ECP) materials processing in which multiple electromagnetic effects arise. primitive boundary layer conservation equations are transf...

A haemoprotein was purified to apparent homogeneity from Bengal-gram seeds. The purified protein exhibited an absorption maximum at 412 nm (Soret band) that upon reduction with dithionite gave rise to a shift in the Soret band to 426 nm with concomitant appearance of an alpha-band at 559 nm and a beta-band at 530 nm. In the reduced state the Bengal-gram haemoprotein showed reactivity towards CO...

We are investigating the redox chemistry of wild-type (WT) and mutant (1-12G) cytochrome P450 BM3. Absorption spectra in solution feature the Fe(III) Soret at 418 nm for WT and a split Soret for 1-12G at 390 and 418 nm. Voltammetry of the proteins within DDAPSS films on the surface of carbon electrodes reveal nearly identical Fe(III/II) potentials (approximately -200 mV vs Ag/AgCl), but signifi...

The present paper reports on an analytical and numerical study of combined Soret Dufour effects thermosolutal convection in a horizontal porous cavity saturated with electrically conducting binary fluid under magnetic field. walls the system are subject to vertical uniform fluxes heat mass, whereas assumed be adiabatic impermeable. main governing parameters problem Rayleigh, Hartmann, Soret, Le...

The globins from sperm whale and from Aplysia limacina myoglobins were reconstituted by addition of stoichiometric ferric protohaem and the Soret c.d. was followed as a function of time. For both reconstituted proteins, the Soret c.d. changes with time, reflecting haem reorientation inside its pocket, as previously described [Aojula, Wilson & Drake (1986) Biochem. J. 237, 613-616] for sperm wha...

An Escherichia coli expression system has been developed for pea cytosolic ascorbate peroxidase (APX). The enzyme was expressed as a fusion product with the E. coli maltose-binding protein for rapid, affinity chromatography purification. Recombinant ascorbate peroxidase (rAPX) was purified by tryptic digestion to separate the maltose-binding protein from rAPX followed by three chromatographic s...
