Replacing Corn and Soybean Meal in Lactating Dairy Cow Diets with Field Peas (Pisum Sativum)
… had a quadratic response. The predicted DMI for NRC was about 2 kg greater (24.2 vs. 22.1 kg/d) than for AMTS across all diets with the actual DMI being 23 .6 kg/d. Both the NRC and AMTS had diet CP increasing from 16.5 to 17.3% as FP inclusion increased, similar to the actual CP of the diets fed …

Epistemological Authenticity in Science Classrooms
… activity that produces it, scientific inquiry. (NRC, 1996; AAAS, 1993) In support of these goals the National Science Education Standards (NRC, 1996) envisions science classrooms where students engage productively in activity that is similar to scientific inquiry. It is presumed that by engaging …

Estimate of radiation release from MIT reactor with low enriched uranium (LEU) core during maximum hypothetical accident
In accordance with a 1986 NRC ruling, the MIT Research Reactor (MITR) is planning on converting from the use of highly enriched uranium (HEU) to low enriched uranium (LEU) for fuel. A component of the conversion analysis includes calculating the maximum hypothetical accident (MHA) dose implications …
