Structure Data of Free Polyatomic MoleculesMolecules containing Three or Four Carbon AtomsThe chemical 1,3-Butadiene recently has been classified as a potential occupational carcinogen; subsequently, a reduction in the 8 hr TWA from 1000 ppm to 10 ppm has been proposed. Substantial quantities of 1...

The overall structure of the method is shown in Figure 8.1. The procedure is to calculate the F&EI and to use this to determine fire protection measures and, in combination with a Damage Factor, to derive the base MPPD. This is then used, in combination with the loss control credits, to...

Each potential reactive complex can be selected to be visualized as a three-dimensional structure. The blue transparent spheres in this structure represent the reactive sites of the specific structure. The pull-down menus on the bottom then allow one to add the next exploration step to the ...

Because some students will try to get away with doing the least amount of effort (which, of course, leads to the least amount of learning), it is necessary to build in structure and scaffolding with tight rubrics for what is expected. That is why I use peer critique and revision as an...
