So, the question is, Do you have multiple instantiations of this laboratory in various parts of Kodak Park, or is it just located in one place with a high-density of chemists in the area?
David McLaughlin: The walk-up facilities are located in areas where there are high densities of people that need to use it. So, for example, in the main research complex where a lot of synthetic organic chemists are located, there is a concentration of analytical tools for structural characterization. In Kodak Park where the scale-up and delivery to manufacturing operation occur, there is, also, a lot of synthetic work that goes on. So, we have a very similar facility, but with techniques that are suited specifically to that environment. In yet another set of buildings there is testing of emulsions and photographic properties.
So, the walk-up facilities are distributed where the need is. When we first put up a walk-up facility there was only an NMR. We put it on the second floor. There was another NMR on the third floor. The chemists on the sixth floor would come and use the one in the walk-up facility on the second floor. The ones on the third floor would generally use the one on the third floor, even though it was an old instrument and gave poorer-quality results. They used it because it was convenient. Convenience is a big part of it. It is similar to the ease of use I described for the Web interface. If you create an easy, simple-to-use interface, then all of a sudden lots of chemists will begin using it. So, you do need to locate the walk-up facilities close to where they are needed.
