The present paper investigates the combined effects of Soret and Dufour on free convective heat and mass transfer on the unsteady one-dimensional boundary layer flow over a vertical channel in the presence of viscous dissipation and constant suction. The governing partial differential equations are solved numerically using the implicit Crank-Nicolson method. The velocity, temperature, and conce...

In the present approach, a two-dimensional steady MHD free convection flow and mass transfer over a stretching sheet has been analyzed numerically including the Dufour and Soret effects with a magnetic field. The governing differential equations of the problem have been transformed into a system of non-dimensional differential equations, which are then solved numerically using a sixth-order Run...

In cointegrating regressions, available estimators and test statistics are nuisance parameter dependent. This paper addresses this problem as an identi…cation failure. We focus on set estimation of long-run coe¢ cients (denoted ). We check whether and to what degree popular estimation methods, speci…cally the Maximum Likelihood of Johansen (1995), Fully Modi…ed OLS [Phillips and Hansen (1990); ...

Linear stability of double diffusive convection of Darcy-Maxwell fluid with Soret and Dufour effects is investigated. The effects of the Soret and Dufour numbers, Lewis number, relaxation time and solutal Darcy Rayleigh number on the stationary and oscillatory convection are presented graphically. The Dufour number enhances the stability of Darcy-Maxwell fluid for stationary convection while it...

The present article exploits a novel application of AI-based Levenberg–Marquardt scheme with backpropagated neural network (LMS–BPNN) to analyze the double-diffusive free convection nanofluid flow model (DDFC-NFM) over an inclined plate in existence Brownian motion and thermophoresis properties embedded porous medium. governing PDEs representing DDFC-NFM are transformed into system nonlinear OD...

The focus of this treatise is on the scrutiny MHD heat and mass transfer motion upper convection Maxwell (UCM) fluid in a thermally radiated flat plate. models flow equations were considered when there temperature difference: Cattaneo-Christov model Soret-Dufour mechanisms. A magnetic field firmness was inflicted opposition to flow. inspection controlled by partial differential (PDEs). Suitable...

A search for the products of fusion reactions that could be triggered by sparking in hydrogen isotopes was carried out. No signatures above background were found. On the contrary, the excess energy production was confirmed in the simple hydrogen/palladium system. The formation of a tightly bound state of the hydrogen (deuterium) atom is hypothesized to explain these results.

The current research is prepared to address the transport phenomenon in a hydro-magnetized flow model on porous stretching sheet. Mass and heat are modeled via temperature dependent models of thermal conductivity diffusion coefficients. Accordingly, involvement radiation, chemical reaction, Dufour effect, Soret effect involved. presenting expression has been boundary layer approximation produce...

The venom apparatus of four hymenopterous parasitoids, including two bethylids, C. tarsalis (Ashmead) and C. waterstoni (Gahan), and two pteromalids, A. calandrae (Howard) and P. cerealellae (Ashmead), were removed and the associated Dufour glands characterized with respect to their external morphology and chemistry. Dufour glands in all four species have a characteristic translucent appearance...

Minor workers of the ant Zacryptocerus pusillus have unusual exocrine secretions in both their mandibular and Dufour glands. The mandibular glands contain a 3:1 mixture of 4-heptanone and 4-heptanol, a mixture found only in the related species Z. varians. The Dufour gland contains a mixture of 13 aldehydes from C9 to C18, not previously encountered in ant secretions. The venom glands gave varia...
