Electricity and Magnetism Flash Animations

josh — Wed, 22 Feb 2012 16:39:09 +0000

Several physics animations, including the following...

Coulomb's Law
A simulation of an experiment to determine the dependence of the electrostatic force on distance.

Comparing a DC circuit to the flow of water.
A simple DC circuit has a DC voltage source lighting a light bulb. Also shown is a hydraulic system in which water drives a turbine. The two systems are shown to be similar.

A Light Switch
A simple animation of how a common light Switch works.

Field Lines
Illustrating representing an electric field with field lines.

A Simple Buzzer
A simple buzzer consisting of a battery, a flexibile metal strip, a piece of iron, and some wire.

Electric Field of an Oscillating Charge
An electric charge is executing simple harmonic motion, and the animation shows the electric field lines around it.

Electric and Magnetic Fields of an Oscillating Charge
A 3 dimensional animation of the "far" fields of an oscillating charge.

Circular Polarisation
Circular polarisation generated from a linearly polarised electromagnetic wave by a quarter-wave plate.

Spinning Charges and an Inhomogeneous Magnetic Field 1
A spinning charged object passes through an inhomogeneous magnetic field. This animation is also used in a discussion of the Stern-Gerlach experiment.

Spinning Charges and an Inhomogeneous Magnetic Field 2
A spinning charged object passes through an array of 3 magnets each producing an inhomogeneous magnetic field. This animation is also used in a discussion of the Stern-Gerlach experiment.

How Malaria Works (life cycle)

glimlag — Thu, 09 Feb 2012 21:59:36 +0000

malaria life cycle in man and mosquito.......

Very good images and a good explanation of how malaria infects both human and mosquito systems. Good watch!

Plasmodium life cycle terms::

Sporozoites - what is injected into the next host

Trophozoite - what is growing the the hepatocytes *exoerythrocytic cycle

Merozoites - what leaves the liver and enters the RBCs --> ring stage --> kill RBC --> infect more RBCs or become gametocytes to be taken up by another mosquito --> gametes in mosquito

paroxysms - the symptoms of malaria from toxins released with RBC lysis

Good ETC Animation.

A video describing the classical complement system

christoff — Mon, 21 Nov 2011 00:06:31 +0000

This is an excellent representation of the classical complement system. I think this is one of the more complete videos I have seen. The classical complement system is the last to be activated and starts with C1 being activated by IgM or IgG (needs two molecules of IgG within close proximity.)

Animation Quiz 1 - Activation of Complement

christoff — Sun, 20 Nov 2011 20:51:57 +0000

A very nice basic animation about complement activation. This will do well for a quick review of complement activation. Additionally this has a 5 question quiz to test yourself afterwards.

A story to help remember the alternate pathway of the immune complement

christoff — Thu, 17 Nov 2011 06:41:43 +0000

It helps me to memorize rogue non-descript terms such as found in complement by tying it to a story.

Chapter 1 - The alternative pathway

Clone3 (C3) was out for a swim(in solution) when his stiches holding his arm together started dissolving due to the water. A beach guard(B) noticed the trouble and started pulling the injured C3(iC3) towards the shore (iC3B). Soon a duck(D) came and started pecking at the beach guard's arm which eventually came off(Ba), leaving the rest of the beach guard(Bb) with injured C3(iC3Bb). A second Clone3(different C3) noticed the trouble and came to the rescue, but in the process of saving the two he rips iC3's arm(C3a anaphylotoxin) off. They swim together(C3b2Bb a C5 convertase) and eventually gets to the beach(cell surface) where C3bBb gets anchored. It now becomes a C3 convertase converting other clone3's into C3b's and anchoring them to the beach.

Chapter 1b -Controlling the C3 convertase

Some beaches(non-self) believe it is proper for C3bBb to convert other clone3's. So mayor properdin encourages them to continue and keeps those who wants to stop the converting away from the convertase(C3bBb).

Other beaches(non-self) do not like the conversions and send in their two swedish goons Hans(H) and Ignus(I) to take care of this fool. Hans holds C3b while Ignus cuts his head off.

The last land mass(self) does not want the conversion and it sends Daffy duck(DAF) and MCP(can't think of something here) to disable this convertase. (lost creative will power)
