Population Dynamics

We are trying to find answers to these problems and questions:

Bacteria change size.
- Minimum size
  - When the bacterium will be at the minimum size?
  - How fast the bacterium increase its dimension?
- Maximum size
  - When the bacterium will be to the maximum size?
- There is same relationship between velocity and size?

Separation.
- When this happen?
- Where the bacterium get placed?
  - Maybe following the bacterium motion?
  - Random?
  - Fluid dynamics?
- Motion properties after the separation.
  - Velocity after separation.
- The two bacteria after the separation have the same size?

Genetic information
- After the separation the two bacteria have the same genetic properties:
  - same replication time distribution?
  - or the new one has a normal/uniform distribution on the normal/uniform distribution of the oldest one?

Growth
- Rate of growth
- Connection between the rate of duplication and the growth phase.

Standing phase
- One bacterium can "kill" another one to make its replication?
  - If yes which one is going to die?

Environment
- we can try to model a variable condition of the environment:
  - 100% Suitable for the replication of the bacteria
  - 80% Suitable for the replication of the bacteria
  - and so on...

Problems

The most popular replication time for an E.Coli is about 20/25 minutes.
Can our simulation take so long time?
How can we simulate on "world" day with 400 bacteria?
