I'm a student of civil engineering and I'm making my final thesis. I'm
colaborating in one project of investigation in order to develop a
system that scans mammographies. We are interested in analizing the
factors that are involved in the motion of one film (mammography film,
where the mammography has been done) with a glass plate, concretely in
the factors that affect the friction of the film with the glass plate.
We know that there is one component of friction, other component of
adhesion and one component of static electricity. My proffesors have
also suggested that there is one more component of suction related
with the low pressure that can be reached underneath the film due to
the motion of the film. This component might increase the adhesion and
therefore the friction. We would like to quantify these four factors
for the motion of the mammography films with different types of
commercial glass plates (for example made of different polymers,
anti-static ones etc) and we would like to have more information about
this phenomena of suction, because we haven't been able to find
anything about it.

Hi -

Are you sure you wanted this question posted 3 times?

I want it posted only once. I made a mistake with  the questions and I
sended it three times and not once as I'd have wanted.
