Tips on Writing the Case Study - Purdue University

Each situation or scene in a case study should either: (1) carry the narrative forward, (2) relate directly to one of the major problems in the case, or (3) provide insight into the personality and motives of one or more of the characters. The ideal situation is one that the writer knows will elicit conflicting opinions about potential solutions.

can cycle carbon among various pools within ecosystems and eventually releases it back to the atmosphere. Viewing the Earth as a whole, individual cycles like this are linked to others involving oceans, rocks, etc. on a range of spatial and temporal scales to form an integrated global carbon cycle (Figure 2). On the shortest time scales, of

EPA Information - Photochemical smog — what it means for us

Nitrogen is not in the actual fuels used in motor vehicles or power stations; it is introduced from the air when combustion occurs. Using less air in combustion can reduce emissions of nitrogen oxides. Temperature also has an effect on emissions—the lower the temperature of combustion, the lower the production of nitrogen oxides.
