Hi,
Thank you for your responses to my crazed pots issue.
Since I got several feedback, I would like to inform you that I am aware =
of pitfalls in this kind of experiments: First of all, it is difficult =
to uniformalize the size and area of the crazed areas and the =
reproducibility of such. Statistical significance always becomes an =
issue in biological experiments. It is our intuitive thinking that the =
crazed areas are conducive to bacterial temporary lodging. Remember, =
that when we buy drinking water, it is not made sterile. Many bacteria =
are waterborn, which are for the most part harmless to man.
Subsurface like crazed areas with little food, are probably not favored =
by all kinds of bacteria, as evidenced by the fact that those bacteria =
living in the subsurface of our skin are usually not those with fecal =
origin. =20
I shall continue to think about a simple but a semiquantitative and =
semiqualitative way to determine the results, which we and our customer =
can agree. It is like when a doctor tells you that you got a heavy =
bacterial infection in your kidney or bladder, but if you ask, how heavy =
is heavy, and the doctor can not answer in a quantitative expression, we =
got a problem. In the meantime I am trying hard to put a mug-handle =
straight. Mariko
