Numerical Solution of Casson Nanofluid Flow Over a Non-linear Inclined Surface With Soret and Dufour Effects by Keller-Box Method

open access: yesFrontiers in Physics, 2019
In this article, the effects of a Casson Nanofluid boundary layer flow, over an inclined extending surface with Soret and Dufour, is scrutinized. The model used in this study is based on the Buongiorno model of the thermal efficiencies of the fluid flows

Huge Seebeck coefficients in non-aqueous electrolytes

open access: yes, 2011
The Seeebeck coefficients of the non-aqueous electrolytes tetrabutylammonium nitrate, tetraoctylphosphonium bromide and tetradodecylammonium nitrate in 1-octanol, 1-dodecanol and ethylene-glycol are measured in a temperature range from T=30 to T=45 C ...

Severity of perineal tears and deviations in perineal body anatomy: A three‐dimensional ultrasound study

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
Sonographic deviations in the muscles fusing into the perineal body were increasingly common with greater perineal tear severity 1 year after delivery in primiparous women. Abstract Introduction Perineal tears are classified into four degrees based on severity.

Training and validation of an automated algorithm to differentiate no and minimal diabetic retinopathy from more severe stages in wide‐field images

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Diabetic retinopathy (DR) is a leading cause of blindness in the working‐age population. Screening is essential to identify and treat sight‐threatening stages prior to irreversible visual loss. This study aimed to train and validate an automated algorithm to identify no or minimal DR, potentially saving resources for specialist ...

Heterogeneous nanofluids: natural convection heat transfer enhancement

open access: yesNanoscale Research Letters, 2011
Convective heat transfer using different nanofluid types is investigated. The domain is differentially heated and nanofluids are treated as heterogeneous mixtures with weak solutal diffusivity and possible Soret separation.

Symmetry Analysis of Equations for Convection [PDF]

open access: yes, 2008
The differential equations describing convection in binary mixture with Soret and Dufour effects are considered. The symmetry classification of these equations with respect to the constant parameters is made.

Standing wave oscillations in binary mixture convection: from onset via symmetry breaking to period doubling into chaos

open access: yes, 2004
Oscillatory solution branches of the hydrodynamic field equations describing convection in the form of a standing wave (SW) in binary fluid mixtures heated from below are determined completely for several negative Soret coefficients.

Dufour and Soret effects in a magnetized and nonmagnetized plasma

open access: yesPhysics of Plasmas, 2007
It is well known that magnetic fields affect heat conduction in a different way in the direction parallel and perpendicular to the field. In this paper, a formal derivation of this phenomenon and analytical expressions for the transport coefficients based in the Boltzmann equation are presented. Moreover, the Dufour effect or diffusion thermo-effect is

Afamelanotide improves quality of life and light tolerance in Austrian erythropoietic protoporphyria patients

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Erythropoietic protoporphyria (EPP) is a rare genetic disorder characterized by severe phototoxic reactions that occur within minutes of light exposure. In clinical studies, afamelanotide has been shown to prolong pain‐free sun exposure, improve quality of life, and reduce the frequency and severity of phototoxic reactions ...
