Abstract In winter 2019, an excursion to the central and eastern parts of Georgia was conducted, focusing on arboreal species other carabids overwintering under bark or at base trunks. Other habitat structures were also investigated. The work done as part ongoing studies in preparation a new checklist Georgian Ground Beetles contribute faunistic well ecological knowledge for main natural areas ...

abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...

The transport of heat and mass from the surface a cylinder coated with catalyst subject to an impinging flow Casson rheological fluid is investigated. features circumferentially non-uniform transpiration embedded inside homogeneous porous medium. non-equilibrium thermodynamics problem, including Soret Dufour effects local thermal in medium, are considered. Through introduction similarity variab...

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...

We present an experimental investigation of Rayleigh-Bénard convection in binary-gas mixtures. In order to interpret the results quantitatively, we determined the necessary thermodynamic and transport properties for six mixtures ~He-CO2, He-SF6, He-Xe, Ne-Ar, Ar-CO2, and H2-Xe! by a combination of data from the literature, molecular-theory calculations, and thermal-conductivity measurements. Al...

In this paper thermophoretic particle deposition on an unsteady magnetodydrodynamic (MHD) free convective heat and mass transfer flow along an impulsively started infinite inclined porous plate under the influence of Dufour-Soret effects have been studied numerically. The transformed governing equations obtained by similarity transformations are solved by shooting method. Comparison with previo...

Our main focus in this paper is to investigate the effects of Soret and Dufour known as thermodiffusion diffusion-thermo on moving plate copper water nanofluid. The set partial differential equations are converted into ordinary using appropriate similarity variables before being solved numerically bvp4c code Matlab software. results heat mass transfer, temperature concentration profiles well pr...
