Port-Hamiltonian formulation for plasma control in Tokamak reactors Trang VU‚ Laurent LEFEVRE and Bernhard MASCHKE Abstract— A port-Hamiltonian model is derived for tokamak plasma current profile dynamics. Magnetohydrodynamics and energy balance equations are first written in port-Hamiltonian formalism using Stokes-Dirac structures in 3D forms and a specific interconnection structure for the magneto-hydrodynamical coupling. A balance preserving reduction scheme is applied to the 3D models‚ assuming

Aurora Borealis The Aurora Borealis is a beautiful display of lights created by nature that appear in the night sky. "Aurora Borealis"‚ the Latin name of the aurora of the northern hemisphere‚ means the red dawn of the north. The name comes from the famous Italian scientist Galileo Galilei who‚ among other things‚ studied the lights around the year 1600. In Rome‚ were Galileo was living‚ the red color dominates‚ but the most common color is actually greenish-yellow‚ which I will cover later in the

The plasma or cell membrane exhibits ability for the cell to discriminate in its chemical exchanges with its environment and this makes cell membrane fundamental to life. This property can only be possible because of the cell membrane’s selective permeability (Campbell and Reece‚ 2002). The structure of the membrane can be best illustrated by the fluid mosaic model where the membrane is said to be a fluid structure with various proteins embedded in or attached to a bilayer of phospholipids (Campbell

Saving a Life: Blood Donation Deana Taylor February 8‚ 2013 I. Introduction A. Attention-Getter- Merriam-Webster Dictionary defines blood as‚ “the fluid that circulates in the heart‚ arteries‚ capillaries‚ and veins of a vertebrate animal carrying nourishment and oxygen to and bringing away waste products from all parts of the body.” Blood is the essence of life itself created in our own bodies in the bone marrow. B. Blood donation is a relatively simple process that can save lives

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to
