The hydrophobic interior cavity of a self-assembled supramolecular assembly exploits the hydrophobic effect for the encapsulation of tertiary amides. Variable temperature 1H NMR experiments reveal that the free energy barrier for rotation around the C-N amide bond is lowered by up to 3.6 kcal/mol upon encapsulation. The hydrophobic cavity of the assembly is able to stabilize the less polar transition state of the amide rotation process. Carbon-13 labeling studies showed that the {sup 13}C NMR carbonyl resonance increases with temperature for the encapsulated amides which suggests that the assembly is able to favor a twisted for of the amide.

The anode ablation rate is investigated as a function of anode diameter for a carbon nanotube arc plasma. It is found that anomalously high ablation occurs for small anode diameters. This result is explained by the formation of a positive anode sheath. The increased ablation rate due to this positive anode sheath could imply greater production rate for carbon nanotubes.

We discuss a class of gauge mediated supersymmetry breaking models with conformal invariance above the messenger mass scale (conformal gauge mediation). The spectrum of the supersymmetric particles including the gravitino is uniquely determined by the messenger mass. When the conformal fixed point is strongly interacting, it predicts a light gravitino of mass m{sub 3/2} < O(10) eV, which is attractive since such a light gravitino causes no problem in cosmology.

We report the detection of early (60-230 s) optical emission of the gamma-ray burst afterglow of GRB071010B. No significant correlation with the prompt {gamma}-ray emission was found. Our high time-resolution data combining with other measurements within 2 days after the burst indicate that GRB071010B is composed of a weak early brightening ({alpha} {approx} 0.6), probably caused by the peak frequency passing through the optical wavelengths, followed by a decay ({alpha} {approx} -0.51), attributed to continuous energy injection by patchy jets.

This report covers the recent background of the Exon-Florio provision with special regards to issues faced in the 112th Congress. The Exon-Florio provision grants the President the authority to block proposed or pending foreign acquisitions of "persons engaged in interstate commerce in the United States" that threaten to impair the national security.

This report discusses the federal minimum wage in American Samoa. Under the Fair Labor Standards Act (FLSA), the minimum wage for the islands is fixed by a commission established by the Secretary of Labor. The minimum wage for fish processing is currently $3.26 an hour. Were Congress to extend the general (federal) minimum wage to American Samoa (and raise it to $7.25 an hour, as is currently proposed), the fish processing industry might absorb the increase, change the way it processes tuna, or migrate to other low-wage countries.

Washington Safety Management Solutions, LLC developed web-based software to improve the efficiency and consistency of hazard identification and analysis, control selection and classification, and to standardize analysis reporting at Savannah River Site. In the new nuclear age, information technology provides methods to improve the efficiency of the documented safety analysis development process which includes hazard analysis activities. This software provides a web interface that interacts with a relational database to support analysis, record data, and to ensure reporting consistency. A team of subject matter experts participated in a series of meetings to review the associated processes and procedures for requirements and standard practices. Through these meetings, a set of software requirements were developed and compiled into a requirements traceability matrix from which software could be developed. The software was tested to ensure compliance with the requirements. Training was provided to the hazard analysis leads. Hazard analysis teams using the software have verified its operability. The software has been classified as NQA-1, Level D, as it supports the analysis team but does not perform the analysis. The software can be transported to other sites with alternate risk schemes. The software is being used to support the development of 14 hazard analyses. …

A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, several mining tragedies led the Congress to pass the Mine Improvement and New Emergency Response Act of 2006 (MINER Act). The law required underground coal mine operators to develop emergency response plans that contain several components designed to improve accident preparedness and response, including providing a refuge of air to miners trapped underground after an accident and wireless communications systems. The Mine Safety and Health Administration (MSHA) is responsible for approving the plans and ensuring their implementation. GAO examined (1) the effectiveness of the approval process, (2) the status of implementation of the plans, and (3) MSHA's efforts to enforce and oversee implementation. To address these questions, GAO reviewed a nonprobability sample of emergency response plans, analyzed MSHA data, and interviewed MSHA officials and members of the mining community."
