Demand for bioenergy is increasing, but the ecological consequences of bioenergy crop production on working lands remain unresolved. Corn is currently a dominant bioenergy crop, but perennial grasslands could produce renewable bioenergy resources and enhance biodiversity. Grassland bird populations have declined in recent decades and may particularly benefit from perennial grasslands grown for ...

Abstract: A dual mixed finite element method, for quasi–Newtonian fluid flow obeying the power law or the Carreau law, is constructed and analyzed in Farhloul–Zine [13]. This mixed formulation possesses good local (i.e., at element level) conservation properties (conservation of the momentum and the mass) as in the finite volume methods. In Farhloul–Zine [12], we developed an a posteriori error...

The paper is concerned with experimental investigations and numerical simulations of immiscible flows in microchannels in the presence of interfacial surface tension. The aim of the present study is to model the unsteady dynamics of the vortical structures and interface shape in the Y-branching geometries with square cross-sections. The tested fluids are Newtonian and weakly elastic polyacrylam...

In the current study, non-Newtonian flow pattern and heat transfer in an enclosure containing a tilted square are examined. In order to numerically simulate the problem, the mesoscopic lattice Boltzmann method is utilized. The non-Newtonian Carreau-Yasuda model is employed. It is able to adequately handle the shear-thinning case. The simulation results of flow and heat transfer have been ...

An 18-week-old umbrella cockatoo presented for continuous vocalization and one episode of regurgitation. The bird had been purchased 3 weeks before presentation and was the first large pet bird owned by this family. The cockatoo was fed a commercial baby bird formula that the owners were heating in the microwave before feeding. The owner had been instructed on formula feeding by the pet store p...

Abstract A simplified model of the bird skeleton along with elongation parameters for the flight feathers is used to explore the diversity of bird shapes. Varying the small number of parameters simulates a wide range of observed bird silhouettes. The model may serve to examine developmental factors involved in these forms, help museum curators develop computational approaches to bird morphometr...

The motion of a long gas bubble in confined capillary tube is ubiquitous wide range engineering and biological applications. While the understanding deposited thin viscous film near wall Newtonian fluids well developed, deposition dynamics commonly encountered non-Newtonian remains much less studied. Here, we investigate moving shear-thinning with systematic experiments, varying zero-shear-rate...
