The Cell Membrane and Movements of Molecules The Plasma Membrane The Plasma Membrane (aka cell membrane) Boundary between the cell and its environment Controls what enters and leaves the cell--- performing homeostasis Has selective permeability- the ability to allow some molecules through the membrane -but not others (aka semi-permeability) Plasma Membrane Water Plasma Membrane Structure Fluid Mosaic Model describes the structure of the plasma membrane Fluid:
Air from travelling through the structure, that will otherwise increase the Air permeability of the building leading to increased energy usage.
Air Permeability - A permeable material is defined as "Capable of being passed through or permeated, especially by liquids or gases"
TURNS RATIO A simple transformer consists of two coils, a primary and a secondary, wound on a high permeability, soft iron core.

B H ( is the permeability coefficient of the media) Solving those equations for homogeneous media that lacks charges and currents, and applying the Lagrange vector identity of 2 , yields the wave equation (eq.5), 1 2 5 E 2 2 E c t Where c 3108 m / s is the speed of light in free space, 2 is the Laplace 2 operator, and t stands for time in seconds (or nano-seconds).
10/2014 – 9/2018 (Expected) A Computational Geophysics project to deliver new efficient simulation techniques and MATLAB code for Non-Smooth Permeability Evolution to compute whether natural or human subsurface fluid flow (fracking, CCS), could trigger earthquakes.
