New yttrium evaluated cross sections and impact on 88-Y(n,2n)87-Y radchem (open access)

New yttrium evaluated cross sections and impact on 88-Y(n,2n)87-Y radchem

We evaluate new n+{sup 89}Y radchem cross sections using recent LANSCE/GEANIE measurements and GNASH nuclear model calculations, together with previous measurements at Livermore by Dietrich et al. A quantification of margins and uncertainties (QMU) analysis leads to evaluated cross sections for the (n,2n) population of the {sup 88}Y ground state and m1, m2 isomers, together with uncertainties. Our new results agree with historic radchem database cross sections within a few percent below 15 MeV (with larger differences above 15 MeV) and they therefore provide a validation of the historic Arthur work that is used in LANL simulation codes. Since the (n,2n) cross sections to the {sup 88}Y g.s. and m1, m2 isomers impact the average {sup 88}Y(n,2n){sup 87}Y cross section at leading-order, we determine the new 14.1 MeV average {sup 88}Y(n,2n){sup 87}Y cross section (crucially important for radchem). Our new 14 MeV average {sup 88}Y(n,2n){sup 87}Y cross section is 1107 mb ({+-} 4%) which agrees with the value obtained from the historic Arthur cross section data to 0.7%.

Prescription Drugs: State Monitoring Programs May Help to Reduce Illegal Diversion (open access)

Prescription Drugs: State Monitoring Programs May Help to Reduce Illegal Diversion

Testimony issued by the General Accounting Office with an abstract that begins "The increasing diversion of prescription drugs for illegal purposes or abuse is a disturbing trend in the nation's battle against drug abuse. Diversion can include such activities as prescription forgery and "doctor shopping" by individuals who visit numerous physicians to obtain multiple prescriptions. The most frequently diverted prescription drugs are controlled substances that are prone to abuse, addiction, and dependence, such as hydrocodone (the active ingredient in Lortab and many other drugs) and oxycodone (the active ingredient in OxyContin and many other drugs). Some states use prescription drug monitoring programs to control illegal diversion of prescription drugs that are controlled substances. GAO was asked to examine (1) how state monitoring programs compare in terms of their objectives and operation and (2) the impact of state monitoring programs on illegal diversion of prescription drugs. This testimony is based on GAO's report, Prescription Drugs: State Monitoring Programs Provide Useful Tool to Reduce Diversion, GAO-02-634 (May 17, 2002). In that report, the programs in Kentucky, Utah, and Nevada were selected for more in-depth study because they were the most recently established programs at the time."

Searches for Higgs at CDF (open access)

Searches for Higgs at CDF

The Higgs boson is predicted to play a crucial role in the dynamics of electroweak symmetry breaking. The search for this yet-unseen state is an important part of the Run 2 physics program at the Tevatron. Herein is offered a brief description of the latest Run 1 Higgs results from CDF, as well as an early Run 2 result.

Seismic Response Prediction of Nupec's Field Model Tests of Npp Structures With Adjacent Building Effect. (open access)

Seismic Response Prediction of Nupec's Field Model Tests of Npp Structures With Adjacent Building Effect.

As part of a verification test program for seismic analysis computer codes for Nuclear Power Plant (NPP) structures, the Nuclear Power Engineering Corporation (NUPEC) of Japan has conducted a series of field model tests to address the dynamic cross interaction (DCI) effect on the seismic response of NPP structures built in close proximity to each other. The program provided field data to study the methodologies commonly associated with seismic analyses considering the DCI effect. As part of a collaborative program between the United States and Japan on seismic issues related to NPP applications, the U.S. Nuclear Regulatory Commission sponsored a program at Brookhaven National Laboratory (BNL) to perform independent seismic analyses which applied common analysis procedures to predict the building response to recorded earthquake events for the test models with DCI effect. In this study, two large-scale DCI test model configurations were analyzed: (1) twin reactor buildings in close proximity and (2) adjacent reactor and turbine buildings. This paper describes the NUPEC DCI test models, the BNL analysis using the SASSI 2000 program, and comparisons between the BNL analysis results and recorded field responses. To account for large variability in the soil properties, the conventional approach of computing seismic responses …

Selective oxidation of methanol and ethanol on supported ruthenium oxide clusters at low temperatures (open access)

Selective oxidation of methanol and ethanol on supported ruthenium oxide clusters at low temperatures

RuO2 domains supported on SnO2, ZrO2, TiO2, Al2O3, and SiO2 catalyze the oxidative conversion of methanol to formaldehyde, methylformate, and dimethoxymethane with unprecedented rates and high combined selectivity (>99 percent) and yield at low temperatures (300-400 K). Supports influence turnover rates and the ability of RuO2 domains to undergo redox cycles required for oxidation turnovers. Oxidative dehydrogenation turnover rates and rates of stoichiometric reduction of RuO2 in H2 increased in parallel when RuO2 domains were dispersed on more reducible supports. These support effects, the kinetic effects of CH3OH and O2 on reaction rates, and the observed kinetic isotope effects with CH3OD and CD3OD reactants are consistent with a sequence of elementary steps involving kinetically relevant H-abstraction from adsorbed methoxide species using lattice oxygen atoms and with methoxide formation in quasi-equilibrated CH3OH dissociation on nearly stoichiometric RuO2 surfaces. Anaerobic transient experiments confirmed that CH3OH oxidation to HCHO requires lattice oxygen atoms and that selectivities are not influenced by the presence of O2. Residence time effects on selectivity indicate that secondary HCHO-CH3OH acetalization reactions lead to hemiacetal or methoxymethanol intermediates that convert to dimethoxymethane in reactions with CH3OH on support acid sites or dehydrogenate to form methylformate on RuO2 and support redox …
