Simulation of an Oxygen Delignification Reactor in the Kraft Pulp Production Process

D. do Mato Lara [1], J. da Luz Maeiski [1], I. Neitzel [1]
[1] Faculdade de Telêmaco Borba, Telêmaco Borba, PR, Brazil

Oxygen delignification is a technology established worldwide and a common operation in pulp mills that use Kraft cooking. The reasons for using this technology are the reduction of organochlorine compounds in the effluents, and economy of chemicals in the bleaching stage. The objective ... Per saperne di più

Simulation of Adsorption Mechanisms of Methane and Carbon Dioxide in Shale Matrix

Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes

S. Baidya [1], A. M. Hassan [1], B. A. Pazmiño Betancourt [2], J. F. Douglas [2], E. J. Garboczi [3],
[1] Computer Science Electrical Engineering Department, University of Missouri - Kansas City, Kansas City, MO, USA
[2] Materials Science and Engineering Division, National Institute of Standards and Technology, Gaithersburg, MD, USA
[3] Applied Chemicals and Materials Division, National Institute of Standards and Technology, Gaithersburg, MD, USA

Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... Per saperne di più

Nonhomogeneous Heat Transfer Simulation Using a Female Human Model

M. Castellani [1], T. Rioux [1], X. Xu [1],
[1] U.S. Army Research Institute of Environmental Medicine, Natick, MA, USA

Previously researchers have modeled the human body using CAD software to create geometries that are approximately the same shape as the human body. While these CAD designs appear similar, they do not account for complex organ anatomy or sudden changes at the skin surface. Now, the human ... Per saperne di più
