It's fairly easy - just expensive. The device you need is called a CG (graphics generator) and it's the thing that broadcasters use for logos, titles, scoreboards on screen. The low cost CGs are PC based and will cost several hundred dollars. The signal being fed to the screen needs to be routed through the graphics generator where the graphics component is overlaid onto the main signal. A warning: A static image left on a plasma screen is likely to result in the image being burnt onto the screen. If the graphic is left in the same place every time it is used, expect to see it there for ever fairly soon.
they create a flow of electrical currrent that can disturb the resting membrane potential.
Ions can't diffuse across membranes, they must used channels to transport across
I'm going to need a bigger plasma torch for this job... The plasma effect is a computer-based visual effect.
fire+energy=plasma
A plasma TV screen is made up of a grid of tiny pixels filled with gas. An electrical charge is put across these pixels which cause the gas atoms to interact with a phosphor coating to create colours.
Diffusion is what carries materials across the plasma membrane. The diffusion cannot be moved across water.
Active transportation is the material that across plasma membrane. This makes it flow one way.
Active Transport
No.
Besides the concentration of the chemical, the pore size of the plasma membrane, and the osmotic pressure of the cytoplasm - nothing else influences the rate of diffusion of a chemical across a plasma membrane.
plasma mostly consists of water i.e 80% if you mean plasma in your blood stream.If you mean the fourth state of matter plasma,it depends on what elements you used to create it.
