19-electron intermediates in the Ligand Substitution of CpW(CO)3with a Lewis Base

Description: Odd electron species are important intermediates in organometallic chemistry, participating in a variety of catalytic and electron-transfer reactions which produce stable even-electron products. While electron deficient 17-electron (17e) radicals have been well characterized, the possible existence of short-lived 19-electron (19e) radicals has been a subject of continuing investigation. 19e radicals have been postulated as intermediates in the photochemical ligand substitution and disproportion… more

21st Century Challenges: Performance Budgeting Could Help Promote Necessary Reexamination

Description: Testimony issued by the Government Accountability Office with an abstract that begins "As part of its work to improve the management and performance of the federal government, GAO monitors progress and continuing challenges in performance budgeting and the Administration's related initiatives, such as the Program Assessment Rating Tool (PART). In light of the nation's long-term fiscal imbalance and other emerging 21st century challenges, we have also reported that performance budgeting can help… more

Activation Measurements for Thermal Neutrons, U.S. Measurements of 36Cl in Mineral Samples from Hiroshima and Nagasaki; and Measurement of 63 Ni in Copper Samples From Hiroshima by Accelerator Mass Spectrometry

Description: The present paper presents the {sup 36}Cl measurement effort in the US. A large number of {sup 36}Cl measurements have been made in both granite and concrete samples obtained from various locations and distances in Hiroshima and Nagasaki. These measurements employed accelerator mass spectrometry (AMS) to quantify the number of atoms of {sup 36}Cl per atom of total Cl in the sample. Results from these measurements are presented here and discussed in the context of the DS02 dosimetry reevaluation… more

Addition of Tropospheric Chemistry and Aerosols to the NCAR Community Climate System Model

Description: Atmospheric chemistry and aerosols have several important roles in climate change. They affect the Earth's radiative balance directly: cooling the earth by scattering sunlight (aerosols) and warming the Earth by trapping the Earth's thermal radiation (methane, ozone, nitrous oxide, and CFCs are greenhouse gases). Atmospheric chemistry and aerosols also impact many other parts of the climate system: modifying cloud properties (aerosols can be cloud condensation nuclei), fertilizing the biosphere… more

Africa, the G8, and the Blair Initiative

Description: Britain's Prime Minister Blair assumed the rotating presidency of the G8 group of nations (see text box) in January 2005, and he intends to use the July 2005 G8 summit, which he will chair, to push his Africa development initiative. Climate change will be the second focus of the G8 meeting, being called the "Gleneagles summit." The purpose of this report is to provide background on Africa, the G8, and the Gleneagles meeting. It outlines the British proposals and the U.S. reaction to them to dat… more

Air Force Assessment of the Joint Strike Fighter's Aerial Refueling Method

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "The Joint Strike Fighter (JSF) acquisition program is estimated to cost $245 billion to develop and produce three variants of stealthy fighter aircraft--a conventional takeoff and landing variant for the Air Force, an aircraft carrier variant for the Navy, and a short take-off and vertical landing variant for the Marine Corps and Air Force. A major goal of the JSF program is to reduce costs by maximizing… more

Argonne Laboratory Computing Resource Center - FY2004 Report.

Description: In the spring of 2002, Argonne National Laboratory founded the Laboratory Computing Resource Center, and in April 2003 LCRC began full operations with Argonne's first teraflops computing cluster. The LCRC's driving mission is to enable and promote computational science and engineering across the Laboratory, primarily by operating computing facilities and supporting application use and development. This report describes the scientific activities, computing facilities, and usage in the first eigh… more

Army BRAC: Implications of Current Initiatives

Description: Disregard Restriction Header and Footer - A Campaign Quality Army with Joint and Expeditionary Capabilities. The Army is undergoing its biggest restructuring effort in over fifty years to create a campaign quality force with joint and expeditionary capabilities.The Army recognizes that it is still encumbered with facilities no longer needed. These facilities drain resources that could otherwise be spent on transformation, readiness, and needed infrastructure. Base Realignment and Closure (BRAC)… more

Atomic Inference from Weak Gravitational Lensing Data

Description: We present a novel approach to reconstructing the projected mass distribution from the sparse and noisy weak gravitational lensing shear data. The reconstructions are regularized via the knowledge gained from numerical simulations of clusters, with trial mass distributions constructed from n NFW profile ellipsoidal components. The parameters of these ''atoms'' are distributed a priori as in the simulated clusters. Sampling the mass distributions from the atom parameter probability density funct… more

Atomic Scale coexistence of Periodic and quasiperiodic order in a2-fold A1-Ni-Co decagonal quasicrystal surface

Description: Decagonal quasicrystals are made of pairs of atomic planes with pentagonal symmetry periodically stacked along a 10-fold axis. We have investigated the atomic structure of the 2-fold surface of a decagonal Al-Ni-Co quasicrystal using scanning tunneling microscopy (STM). The surface consists of terraces separated by steps of heights 1.9, 4.7, 7.8, and 12.6{angstrom} containing rows of atoms parallel to the 10-fold direction with an internal periodicity of 4{angstrom}. The rows are arranged aperi… more

Attempts to Produce D2-Gas-Filled Be Shells

Description: We have attempted to fabricate some 0.5 mm diameter D{sub 2}-gas-filled Be shells by coating gas-filled PVA-coated GDP mandrels with Cu-doped Be. We find that during the coating all (or most) of the gas leaks out. This is likely due to either small cracks or holes in the coating that are formed at the earliest points and are maintained during the thickness build-up of the coating, and/or to some level of intrinsic porosity in the coating. This memo documents our efforts.
