The present analysis is focused on free convective heat and mass transfer characteristics of magneto-nanofluid flow through a moving vertical plate in the presence of thermal radiation and thermal diffusion. The water-based nanofluid containing copper is taken into consideration. A uniform magnetic field is applied perpendicular to the plate. The governing equations are solved by applying finit...

We have determined the diffusion, thermal diffusion, and Soret coefficients of a poly(dimethyl siloxane)/poly(ethyl-methyl siloxane) (PDMS/PEMS) polymer blend as a function of composition and temperature within the homogeneous phase. The critical slowing down of the diffusion and the corresponding critical divergence of the Soret coefficient are described within the pseudospinodal concept both ...

It is common knowledge that light fluids rise while heavy fluids sink in the gravity field. The most obvious case is the isothermal Rayleigh-Taylor instability when a heavy fluid is placed on top of a light one. In the nonisothermal case, while heating from above, the density stratification is stable in a pure liquid. However, unstable density stratification might be established in a binary mix...

The analysis in this communication addresses the unsteady MHD flow of tangent hyperbolic liquid through a vertical plate. model on mass and heat transport is set up with Joule heating, generation, viscous dissipation, thermal radiation, chemical reaction Soret-Dufour form partial differential equations (PDEs). PDEs are simplified into dimensionless by utilizing suitable quantities. solved spect...

By M. H. F. WILKINS, M.A., PH.D. AND S. DE CARVALHO, M.D. H EME COMPOUNDS have relatively sharp absorption bands ins the visible spectrum w’hich have beers much used to identify heme enzymes ins tissue sections, e.g. the classical work of Keilins.tm These bands are, however, not sufficiently strong for consvensienst estimations of the small amounts of heme in a single cell. The Soret band, at t...

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 (...

The purpose of present article is to examine the peristaltic flow of Jeffrey fluid in a curved channel. An electrically conducting fluid in the presence of radial applied magnetic field is considered. Analysis of heat and mass transfer is carried out. More generalized realistic constraints namely the convective conditions are utilized. Soret and Dufour effects are retained. Problems formulation...

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.

The ability to determine the time since deposition of a bloodstain found at a crime scene could prove invaluable to law enforcement investigators, defining the time frame in which the individual depositing the evidence was present. Although various methods of accomplishing this have been proposed, none has gained widespread use due to poor time resolution and weak age correlation. We have devel...
