Nonlinear absorption of monochromatic radiation near a gas-medium resonance

MHD Jeffrey NanoFluids Flow Over a Stretching Sheet Through a Porous Medium in Presence of Nonlinear Thermal Radiation and Heat Generation/Absorption

In this article, a numerical investigation of magnetohydrodynamic non-Newtonian nanofluid flow on a stretching sheet through an isotropic porous medium. The effects of both non-linear thermal radiation and heat generation/absorption were studied on distributions of velocity, temperature and concentration. On the other side, the governing partial differential equations have been transformed by u...

Inverse Braking Radiation and Resonance Absorption in Corona Plasmas of Inertial Confinement Fusion

Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...

Porous medium equation with absorption and a nonlinear boundary condition

In this paper we study a porous medium equation with a nonlinear absorption term and a nonlinear boundary condition. We prove existence of weak solutions and also we establish some uniqueness and non uniqueness results for certain range of the parameters that appear in the problem. Finally we deal with the existence of global solutions in time or blow-up. We find in which region of parameters t...

Lepomis and Monochromatic Radiation

Measurements on the sensibility of Lepomis to very dim spectral lights have been made with the purpose of testing the hypothesis that the photosensitive retinal pigment, known as visual purple, is responsible for vision at low intensities of illumination. Since the pioneer morphological investigation of Schultze (1866), it has been known that the vertebrate eye usually contains two kinds of pho...
