| |
| - | We are trying to find answers to these problems and questions:
| |
| - |
| |
| - | *Bacteria change [http://www.pubmedcentral.nih.gov/picrender.fcgi?artid=2134870&blobtype=pdf 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 [http://books.google.co.uk/books?id=0SPMLpTxGpMC&pg=PA51&lpg=PA51&dq=e.coli+size+velocity+motion&source=bl&ots=rqCBRQ1IN1&sig=__zft5KeWbLpUodXwGcyvnOBQtM&hl=en&ei=ZUhkSprSKcaZjAeN6IUC&sa=X&oi=book_result&ct=result&resnum=5 velocity and size] ?
| |
| - | **Relationship beetwen size/time/growth rate
| |
| - | ----
| |
| - | *Separation.
| |
| - | **When this happen?
| |
| - | **Where the bacterium get placed?
| |
| - | ***Maybe following the [http://books.google.co.uk/books?id=DjdgXGLoJY8C&printsec=frontcover&dq=E.+coli+in+motion++By+Howard+C.+Berg&source=gbs_similarbooks_s&cad=1 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.<br\>
| |
| - | Can our simulation take so long time?<br\>
| |
| - | How can we simulate on "world" day with 400 bacteria?
