Educating an engineer

Article Abstract:

The University of Pittsburgh has an innovative new learning center for undergraduate chemical engineering students. It is based on a need to improve existing classroom space to accommodate larger classes. Team-based classroom activities and computer-facilitated classroom exercises consistent with active collaborative learning were two of the goals established by a study team. A telemetry system from Cybex was adopted so Windows NT-running CPUs for students could be used remotely. The new learning center, the document cameras, the control system based on a Crestron controller and other innovations are important.

The proof is in the fire

Article Abstract:

The reliability of two international standards for testing for passive fire protection products, intumescent materials, is considered by an independent consultant on passive fire protection in Canada. The two standards are Underwriters Laboratories Standard 1709 and the German Institute for Building Technology Guidelines for Intumescent Building Materials. Intumescents swell when exposed to heat and then chemically bound water absorbs heat. The problems come because they are susceptible to environmental influences such as humidity.

Does CO(sub.2) really drive global warming?

Article Abstract:

Evidence shows that temperature changes are driving changes in carbon dioxide levels, not the reverse. Water, as a gas, is the major radiative absorbing-emitting gas in the atmosphere, averaging 95%. Absorption coefficients for the CO(sub.2) bands at a concentration of 400 ppm are 1-2 orders of magnitude too small to be significant, even with concentrations doubled. Topics include the Arctic Ocean model and the impact of industrialization.
