Increasing concentrations of vitamin B 12 were fed to 144 weanling pigs (weaned 13-14 days) in two, five-week trials.­ Pigs were fed one of six diets: NC, negative control, basal diet without supplemented vitamin B 12 ; or the basal diet with the inclusion of 100% (1X, 7.­94 μg/lb), 200% (2X, 15.­87 μg/lb), 400% (4X, 1.­75 μg/lb), 800% (8X, 6.­49 μg/lb), or 1,600% (16X, 126.­98 μg/lb) of NRC re...

This paper describes a summit on Community Colleges in the Evolving STEM Education Landscape organized by a committee of the National Research Council (NRC) and the National Academy of Engineering (NAE) and held at the Carnegie Institution for Science on December 15, 2011.

Detecting communities plays a vital role in studying group level patterns of a social network and it can be helpful in developing several recommendation systems such as movie recommendation, book recommendation, friend recommendation and so on. Most of the community detection algorithms can detect disjoint communities only, but in the real time scenario, a node can be a member of more than one ...

Amajor effort to establish “scientifically-based research” (SBR) in education has been under way for some time (Feuer, Towne, & Shavelson, 2002). Key manifestations of this effort are found in the No Child Left Behind Act and the reauthorization and reorganization of the Office of Educational Research and Improvement as the Institute for Educational Science (Eisenhart & Towne, 2003).

In March of 1997, the National Research Council (NRC) of the National Academy of Sciences issued the report, "For the Record: Protecting Electronic Health Information." Concluding that the current practices at the majority of health care facilities in the United States are insufficient, the Council delineated both technical and organizational approaches to protecting electronic health informati...

Two experiments were conducted to assess effects of phase-feeding (PF) on broilers from 21 to 63 d. Experiment 1 evaluated the impact of PF on growth performance, whereas experiment 2 assessed the effects of PF on CP intake and nitrogen excretion. Diets were formulated using recommendations from NRC or linear regression equations. Two PF treatments were prepared: standard (PF) and low (PF10), i...
