We sent questionnaires to the program directors of all 396 internal medicine residency training program sites in the country. Information requested included program characteristics, months devoted to float experiences in each year of training, and the location and purpose of the rotation. Program directors were also asked to choose among descriptors characterizing the evaluative process. There were 139 responding programs (39%), 134 with data that could be aggregated. Responding programs were similar to all programs nationally in the distributions of size and university sponsorship. Overall, 76% of programs employed a night float for any period of time, and 71% currently had one, on average for 6.7 years. Mean months of float experience during residency was 2.4 months, significantly longer in programs that were not university based. Float experiences were evaluated in 89% of those programs who employed them, with ten different methods reported. University-based programs were significantly less likely to use chart review as a method of evaluation, but no other differences in methodology were significant. Float rotations are common among internal medicine residency training programs. Evaluative methods vary, but one or more are applied in the vast majority of programs.

The power demanded by a micromachining center while cutting low carbon steel under varied material removal rates was measured to model the specific energy of the machine tool. Thereafter the power demanded was studied for cutting aluminum and polycarbonate work pieces for the purpose of comparing the difference in cutting power demand relative to that of steel.

The use phase incorporated three manufacturing environments: a community shop, a job shop, and a commercial facility. The CO2-equivalent emissions were presented per machined part. While the use phase comprised the majority of the overall emissions, the manufacturing phase emissions were significant especially for the job shop, which is not as efficient as the other facilities due to its inherent need for flexibility. Since the Mori Seiki is heavier, the manufacturing phase of this machine tool had a greater impact on emissions than the Bridgeport. Transportation was small relative to the use phase, which was dominated by cutting, HVAC, and lighting. These results highlight areas for energy reductions in machine tool design as well as the importance of facility type to the manufacture of any product.
