[1] We investigate effects of magnetic self-consistency on ring current development by calculating equatorial particle transport in a model that feeds back the ring current on the magnetospheric configuration. The equatorial magnetic intensity is computed by solving a force-balance equation in the equatorial plane. This force-balance computation is coupled to a kinetic proton and electron drift...

This research focuses on the need for preserving fruits in rural areas to prevent waste. The solar drier is made of vital chambers i.e. the concentrator chamber (that harvests the solar irradiance), the transport pipe (that transports the heat generated by convection) and hanger chamber (where the fruits are placed). The temperature within the concentrator chamber and hanger chamber was monitor...

The onset of dynamo action is investigated within the context of a newly developed low Rossby, low magnetic Prandtl number, convection-driven dynamo model. This multiscale model represents an asymptotically exact form of an α^{2} mean field dynamo model in which the small-scale convection is represented explicitly by finite amplitude, single mode solutions. Both steady and oscillatory convectio...

the fluid flow and heat transfer in a three-dimensional microchannel filled with al2o3- water nanofluid is numerically investigated. the hybrid scheme is used to discretize the convection terms and simpler algorithm is adopted to couple the velocity and pressure field in the momentum equations. the thermal and flow fields were analyzed using different volume fractions of nanoparticles and diffe...

in the present study, the onset of double diffusive reaction-convection in a uid layer with viscous fluid, heated and salted from below subject to chemical equilibrium on the boundaries, has been investigated. linear and nonlinear stability analysis have been performed. for linear analysis normal mode technique is used and for nonlinear analysis minimal representation of truncated fourier serie...

[1] Global auroral images are used to investigate how specific types of solar wind change relate to the resulting type of auroral-region disturbance, with the goal of determining fundamental response types. For not strongly southward IMF conditions (Bz ^ 5 nT), we find that IMF changes that are expected to reduce the convection electric field after^30 min of negative IMF Bz cause typical substo...

We find approximate analytical solutions to the problem of cooling a silicon detector ladder which is internally heated by leakage current caused by radiation damage. The heat generation term has an approximately exponential temperature dependence. Heat is removed by convection and / or conduction to a heat sink. Design equations are derived which prevent thermal runaway, and a wide range of pa...

The status of core collapse supernoova progenitor models is reviewed with a focus on some of the current uncertainties arising from the difficulties of modeling important macrophysics and microphysics. In particular, I look at issues concerned with modeling convection, the implications of the still uncertain C(α, γ)O reaction rate, the uncertainties involved with the incorporation of mass loss,...
